Abstract:
A treadmill exercising apparatus comprising a generally planar frame equipped with a planar slider bed and head and tail rollers journalled respectively at the head and tail ends of the frame, over which an endless nylon belt is trained, with the slider bed having a top, slider, surfacing, formed by plastic sheeting, across which the upper run of the belt rides, and the head and tail rollers being formed from a rigid metallic material and provided with a belt centering crown, which in the case of the head roller is formed by an elastomeric material. The frame at its head end is equipped with a cross member in which are threadedly mounted in spaced apart relation a pair of threaded screw members that support the head end of the frame for adjustment of the slope of the treadmill. The tail end of the frame has a pair of pivotally connected supporting feet, and the feet of the frame tail end and the screw members are proportioned to horizontally dispose the slider bed and associated endless belt in the retracted position of the screw members, with the screw members being journalled to rotate about upright axes that are inclined at an acute angle off perpendicular relationship relative to the slider bed plane for sloping the treadmill as desired.
Abstract:
A beverage carbonator device comprising an outer main container for holding the beverage as it is being, and after it is, carbonated, which is open at its upper end and has a beverage dispensing off-on control valve or spigot at its lower end, and a carbonation generating and pressure regulating assembly arranged for mounting within the container in sealed application to the container open end. The assembly includes a lower carbonating gas generating tank that is to receive and contain the carbonating gas generating substances, which tank is removably connected in sealed relation to an orificed floor of a carbonating gas receiver that is closed at its upper end by a flexible diaphragm, with the receiver in turn being secured to a cover that is part of the assembly and that is sealingly applied to the container upper end. The diaphragm is exposed to a vented breathing chamber it defines with the cover, and the diaphragm is spring biased inwardly of the receiver and carries a link that is operatively connected to a control valve for the receiver floor orifice for controlling the pressure of the carbonating gas in the container that is supplied thereto from a gas emitting conduit connected to the receiver for that purpose, to maintain the carbonating gas in the container at a substantially uniform predetermined level.
Abstract:
A process of making printed circuit boards in which the individual substrates involved are hot set formed from a suitable thermosetting resin and filler composition, with the cure being limited to the resin B stage. The side surfacing of the individual substrates that is to bear the metallic electrically conductive circuiting is catalyzed and then electrolessly plated with copper or the like electrically conductive metallic material to a thickness in the range of from about 50 to about 100 millionths of an inch, and thereafter the thusly plated substrates are hot set to fully cure same and perfect the bond between the substrate and its plating. Each substrate then has a masking and non-conductive resist applied to its plated side (that is to bear the circuit), in a pattern that defines the printed circuit configuration and exposes the underlining electroless plating in the configuration of the circuit for electroplating, after which the substrate is electroplated with copper or the like in the circuit defining voids of the resist thereafter, the resist is stripped from the substrate, and the electroless plating thereby exposed is removed by etching.
Abstract:
A motorized treadmill exercising device comprising a generally planar frame equipped with a planar slider bed and head and tail rollers journalled respectively at the head and tail ends of the frame, over which an endless plastic belt is trained. The treadmill at its head end is equipped with a cross member that pivotally mounts a motor assembly including an electric drive motor and shaft driven by same that is keyed to a variable speed pulley aligned with an ordinary fixed speed pulley keyed to the treadmill belt head roller, and between which a drive pulley belt of the V type is tensioned by the biasing action of the variable speed pulley that subjects the motor assembly to uniform spring biasing action about the pivotal mounting of the motor assembly for tensioning the pulley belt into drive transmitting relation with the respective pulleys, and with the treadmill apparatus including hand hold railing on either side of same between which the treadmill user exercises, with one of the hand rails having mounted on same and connected with the treadmill drive motor assembly for pivoting same, a control mechanism that is adapted for hand actuation by the treadmill user when using the treadmill, for changing of the tensioning of the pulley belt, and the adjustment of the variable speed pulley, for convenient infinitely variable speed changing of this treadmill belt between its maximum and minimum speeds provided by the treadmill apparatus involved and protection of the drive equipment against damage.
Abstract:
A treadmill exercising apparatus comprising a generally planar frame equipped with an inclinable, planar slider bed, a driving head roller, and an idler tail roller, both journalled in the slider bed and respectively at the head and tail ends of the frame, over which an endless belt, formed by a low long term creep or stretch resistant synthetic resin extruded film, oriented of polyester or nylon, is trained, with the slider bed having a top slider surfacing formed from one of the same materials or from Masonite hardboard sheeting, across which the upper run of the belt rides, with the head and tail rollers each being formed from a rigid metallic material and provided with a belt centering crown, which, at least in the case of the driving head roller, is provided with an elastomeric coating or covering that defines the crown surfacing, whereby the coefficient of dynamic friction of the belt riding on the treadmill slider bed is no more than about 0.22, while the coefficient of static friction between the crown surfacing of the treadmill driving roller and the belt is no less than about 0.4, with the belt also being adjustably tension against the rollers to be in slip free tight relation thereto under a tension that is a nominal fraction of the tensile strength of the belt, thereby providing maximized driving efficiency with minimum energy requirements that permit the use of an electric drive motor for walking exercise use of the treadmill that may be less than one horsepower.
Abstract:
A treadmill exercising apparatus comprising a generally planar frame equipped with a planar slider bed and head and tail rollers journalled respectively at the head and tail ends of the frame. The rollers are provided with elastomeric material crowns, over which rollers an endless nylon belt is trained. The frame at its head end is equipped with a cross member in which are threadedly mounted in spaced apart relation a pair of threaded screw members that adjustably support the head end of the frame, with each of said screw members being journalled in its own foot for rotational movement with respect thereto, and with the threaded screw members being coupled together adjacent their upper ends for simultaneous manual operation in the same direction in forward and reverse directions. The screw members shift from an angled position to a substantially vertical position, in firm supporting relation to the treadmill frame, when operated to shift the treadmill frame from horizontal position to the maximum grade effect position. An electric drive motor assembly pivotally mounted on the cross member is spring biased to tension the drive belt stretching between step up and step down pulleys on the head roller and drive motor. A handle on the assembly is used to overcome the spring bias to free the belt for movement between pulleys to change the drive ratio.
Abstract:
A label assembly arrangement with label end finger hold capability for the individual labels, in which the label assembly comprises a carrier sheet and a plurality of pressure sensitive adhesive backed labels that are shaped to be expeditiously separated from the carrier sheet and centered on the desired substrate surface by finger gripping of the label end portions, which in accordance with the invention have the adhesive side of same masked at either end of the label to protect the adhesive during handling. The masking is effected by masking sections delineated and severed from the carrier sheet and removed therefrom when the individual labels are peeled from their carrier sheet.
