An electric gun is provided for the sanitary extruding of comestibles, such as cookie dough, or the like, having an easily disassembled mechanism. Those portions of the gun which are in contact with the food are removable from the drive mechanism to permit sanitary cleaning as well as ease of filling. Reversibility of portions of the mechanism makes reassembly of the gun uncomplicated.

A coatings application apparatus pumps liquid paint through a flexible conduit within a rotary variable displacement peristaltic pump to a conventional applicator head. Through constant speed rotating lobes peristaltic action squeezes coating liquid within the conduit through the paint applicator control handle and applicator.The control handle permits changes in the paint flow rate. Upon constriction of the conduit within the control handle, flow rate is reduced, back pressure develops with resulting tube distortion. Distortion levered forces act upon a pre-set loaded pump spring. Variation in pump displacement results. The liquid flow rate within the supply conduit is inversely proportional to the back pressure so developed. If fluid flow is completely arrested by full supply tube constriction, back pressure becomes a maximum and pump displacement becomes zero. The pump continues to operate, however, at constant R.P.M., requiring no high starting torque.The pump unit employes two reverter train speed reduction systems in tandem. A conventional planetary or epicyclic gear system provides a first reduction in R.P.M. The pump rotor element itself, as a secondary reduction unit, allows economy in selection of a high speed, low power, motor drive for the peristaltic pump.

A liquid mixing valve having a single handle for mixing hot and cold water which incorporates a pair of resilient, tube-like squeeze elements for water passage. A pair of cams, controlled by the handle through a linkage arrangement, restrict the cross-sectional area of the squeeze elements thereby regulating the hot and cold water flow rates.

Adhesive joining system for joining a plurality of superimposed material layers. An elongated needle-like member is reciprocally and rotatably driven along and about its longitudinal axis so that each reciprocation causes the needle to pass through and be withdrawn from the superimposed layers. After the needle has passed through the layers, at least the outer tip is coated with an adhesive material. The adhesive material itself may be in solid, liquid or powdered form and be either heated or unheated. After coating, withdrawal of the needle from the material layers causes the adhesive on the needle to be deposited on the material through a wiping action caused by the pressure of the material exerted against the needle. Rotation of the needle-like member gathers loose fibers from the material layers and wraps them together in the adhesive to form a reinforced joint. Upon full retraction of the needle-like member from piercing contact with the material layers, the pierced area of the layers closes to fill the cavity with adhesive and squeeze it out into the surrounding material to further strenghten the joint. After each reciprocation, the layers may be conveniently advanced in order that a joined or bonded area may be formed along a desired path.

A cabinet has an upper portion which encloses a ram member movable vertically by a motor driven scissor-type actuator from an upper retracted position to a lower extended compacting position within a container positioned within the lower portion of the cabinet. The container is molded of a plastics material and is supported by a two-wheeled cart including pivotal arms which extend around an intermediate portion of the container and are locked together for restraining the container during compacting. When the container is tilted by the cart into a compacting position under the ram member, the container actuates a sealing frame which lowers and engages the upper rim of the container for confining within the upper portion of the cabinet any odors released by the material being compacted within the container.

An apparatus is provided for popping corn by heated air which is circulated in a cylindrical popping chamber having a vertical axis to provide a fluidized bed of swirling and circulating corn to be popped. As the corn is popped, it is lifted upwardly by the moving air and volume of popped corn to form a column of floating corn above the popping chamber and the popped corn is discharged through the open top of the chamber.
摘要:
A portable paint spraying device for generating a paint spray by centrifugally impelling liquid paint from the edge of a vertically oriented spinning disc. The disc is driven by an electric motor which also drives a conveyor screw used to lift the paint upwardly from a reservoir or container through a vertically oriented pump tube and into a spray chamber in the sprayer housing. The pump tube has a horizontal portion at the upper end thereof terminating in a delivery orifice through which the liquid paint is discharged into a centrally located recess or well in the front face of the disc. The disc has a relatively large flat annular region surrounding the central well which is in turn surrounded by an outer peripheral angled flange or lip having a feathered edge. The spray dispersion pattern is defined by a vertically oriented spray discharge slot in the pump housing, a movable shutter between the spray discharge slot and disc, and a series of baffles within the spray chamber which also assist in returning excess liquid to the paint reservoir. The amount of paint exiting from the paint sprayer may be controlled by controlling the amount of overlap between the movable shutter and spray discharge slot; also by diverting a portion of the paint which is lifted by the conveyor screw back to the reservoir instead of delivering same onto the sprayer disc.

A beverage carbonator constructed as a pitcher shaped pressure vessel which functions as a carbonation chamber and which has a water canister and a gas generation chamber removably positioned inside the carbonation chamber. Carbon dioxide is produced by releasing internally stored water from the water canister into a carbon dioxide generating chemical in the gas generation chamber and then the carbon dioxide passes into the carbonation chamber where it is dissolved into a liquid beverage.
