A printing apparatus is provided which includes a print mechanism configured to print in a plurality of color modes, and a controller configured to select an active color mode switching option from among a plurality of color mode switching options, and instruct the print mechanism to switch between the color modes according to the active color mode switching option. Each of the color mode switching options defines a manner in which the printing apparatus and method will switch between the plurality of color modes when printing a document.
摘要:
A printing device receives information that identifies a resource locator, determines from the resource locator the resource and a location of the resource in a resource system, accesses the resource, and prints the resource. The printing device receives the information from a wireless or direct-connect input device, or the printing device receives an image of the information from a scanning device.

An overvoltage protector for protecting equipment, especially telephone equipment, against high voltage surges such as are caused by lightning in the vicinity of the equipment or the cables to which it is connected, comprises one or more overvoltage protectors (42,58) mounted upon one face of an insulating support (18). A generally planar contact member (62) mounted upon the support member has a ground contact member (90) to make contact with a ground electrode (114) in the equipment to be protected and with each overvoltage protector. A spacer (60) of fusible plastics material extending between the contact member (62) and an interconnection (26) to one terminal (42A) of the protector melts when a sustained fault occurs. As the spacer melts, it permits an electrical connection between the contact member and the line to which the overvoltage protector is connected, effectively short-circuiting the line to ground. Overcurrent protection may be provided by means of a resistor (116) disposed in series with the line and located close to the plastics spacer so as to heat the spacer when an overcurrent occurs. In one case, the spacer comprises a film interposed directly between a pair of contacts which serve to short-circuit the protector. In another case, the spacer comprises a limb with relatively thin lateral projections which melt and shear. In both cases, the spacer preferably comprises high density, high molecular weight polyethylene.

This invention is directed to composite coating for maintaining low moisture levels at the surface of solid substrates. One embodiment of the invention comprises a coating having a desiccant layer between layers of the same or different elastomeric polymers. Another embodiment comprises a layer of elastomeric polymer covered with a layer of an elastomeric polymer/desiccant mixture. The composite coating may be applied to integrated circuits to prevent corrosion thereof.

Apparatus (20) for successively supplying substantially equal portions of a flowable comminuted product such as sausage from a source thereof to a delivery zone is disclosed wherein dual product portioning chambers (80, 88, 82, 90) are provided which function such that as meat to be portioned is directed into a first chamber which increases in volume to a predetermined extent, portioned meat is delivered from the other chamber as it decreases in volume to the same predetermined extent. Means (114) is provided externally of the chambers for substantially equalizing the increase and decrease of the effective product-receiving volume of each of the chambers.
摘要:
An improved, slide plate-type patty forming apparatus (20) is provided which preferably includes a reciprocating slide plate (60) with a removable, multiple piston and cavity head (78) adapted to move between a retracted meat-filling position wherein respective patty forming cavities (90) are filled with meat to an extended patty-discharging position wherein formed meat patties (264) are ejected. Each of the patty forming pistons (96) is equipped with a porous bottom plate (104) formed of sintered metal or ceramic, an appropriate compressed air passageways (120, 122, 106) are provided for delivery of air through the bottom plate (104) for cleanly ejecting the formed patty (264). Adjusting mechanism (26) for altering the thickness of formed patties (264) includes a plurality of adjusting units (166) each equipped with a vertically shiftable, piston-engaging foot (176); movement of the feet (176) in unison is effected by means of handwheel (164) and connecting gear train (162, 200, 194, 192, 174). Individual variance of respective patty forming stations can also be accomplished by gear disengagement and manual adjustment.
摘要:
A solid-state surge protection device comprises a semiconductor chip sandwiched between two electrodes. A resilient sealing member or layer comprised of a thermoplastic or thermosetting resin extends around the periphery of the device, adhering to both electrodes, so as to seal the interface region between the chip and each electrode. The resin is a flexible, dielectric material which is not disrupted by heat generated under surge conditions in the device, is environmentally inert, and preferably remains compliant under exteremely cold conditions. The electrodes of the device can move together into electric-conductive contact in the event of chip destruction, or can move back into contact with the chip if separated therefrom by an arc.

An apparatus for the application of coating material onto elongated food products wherein the applicator nozzle and nozzle opening portion of the apparatus correspond to the side surfaces of the elongated food product. The food product to be coated is passed before nozzles discharging impelled coating material from a coating material supply source that meters desired amounts of coating material to the blower device.
摘要:
An overvoltage protection device, especially for telephone equipment and the like, comprises two protectors connected directly in parallel. One protector, for example a back-to-back semiconductor diode, has a breakdown voltage below which it is a high impedance. Between the breakdown voltage and a failure voltage it has a lower impedance. Above the failure voltage it has negligible impedance. The other protector, for example a gas tube, has a range of operating voltages which extends from below the breakdown voltage of the diode, to a voltage between the breakdown voltage and the failure voltage of the diode. In operation the two protectors interact, the diode operating, for example, on faster surges and, in so doing, slowing the surge front so as to increase the likelihood that the gas tube will fire.
