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 a 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.

A solid-state surge protection device comprises two electrodes between which is sandwiched a semiconductor chip. A resilient, annular, sealing member comprised of a thermoplastic resin extends around the periphery of the device and is adhered to both electrodes. The resin is a flexible, dielectric material which is not disrupted by heat generated under surge conditons in the device, and which is environmentally inert. The electrodes can be soldered to opposite surfaces of the chip.

A greatly improved aseptic processing apparatus and method for pumpable foods is provided which gives accurate, uniform aseptic cooking conditions (e.g, time, temperature and pressure) while at the same time preserving the integrity of particulates in the food product. In preferred forms, the apparatus includes a reciprocating piston food pump which generates a continuous product stream at a substantially constant nominal pressure. This stream is fed to a heat exchanger in order to elevate the temperature of the product, whereupon the stream passes through a holding tube to complete the aseptic cooking process. A metering device such as a rotary pump is located downstream of the holding tube for creating a substantially constant flow rate of product from the apparatus. Use of a downstream metering device in conjunction with an upstream constant pressure pump permits attainment of even, relatively high system pressures which in turn facilitates accurate temperature control and eliminates localized internal steam flashing which can deleteriously affect product quality. By virtue of the present apparatus and method, aseptic processing of low acid heterogeneous food products such as stews and chilies can be safely accomplished on a commercial scale.

The cable reel handling apparatus is mountable on a truck and operable to separately lift and move a pair of reels from ground supported positions rearwardly of the truck to transfer positions substantially centered relative to the truck rear wheel and axle assembly and between side compartment units that project above the truck bed and extend longitudinally over the length of the bed. A carriage structure is movable on tracks located above the side compartment units between a forward reel transport position and a rearward reel loading position in which the first reel to be transported is directly transferred by vertically movable lift arms mounted at the rear end of a vehicle to an axle supported position on the carriage structure for movement therewith to the forward reel transport position.

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.

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.

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.
