Abstract: MALFUNCTION DETECTION SYSTEM FOR A MICROPROCESSOR BASED PROGRAMMABLE CONTROLLER                Abstract of the Disclosure Hardware is employed at the I/O interface racks of a programmable controller to detect fault conditions.          An I/O fault line is connected in daisy chain fashion between the I/O interface racks and the controller processor, and when a fault is indicated at any of the I/O interface racks it is communicated to the controller processor.  The indicated I/O fault freezes, or holds, the microprocessor in the controller processor, and if the I/O fault persists for a pre-selected time interval, all operating devices connected to the programmable controller are decontrolled.          Means are also provided in the controller processor for detecting malfunction conditions and when such a condition is detected, the operating devices connected to the programmable controller are decontrolled.

Abstract: METHOD FOR MAKING A SIDE TERMINAL WELD AND PRODUCT PRODUCED BY THAT METHOD                Abstract of the Disclosure An integral and homogeneous connection between a terminal and a battery lug is accomplished without the re-quirement of specially shaped projections on either of the surfaces of the terminal or lug.  Insulation is disposed between the lug and terminal and a portion of the overlap-ping area of the lug is pressed through an opening in the insulation means to make contact over a relatively small area with the terminal.  Welding jaws are used to press the lug and terminal together and a current is provided by the welding jaws to heat up the area of contact so that the lead begins to melt in the opening.  Since the lug and terminal are continuously squeezed together by the welding jaws, more cold lead is introduced into the opening until the entire opening is filled with molten lead from the lug and terminal.

Abstract: Abstract of the Disclosure Radiation-curable compositions consisting essentially of a triorganosiloxane-endblocked polydiorgano-siloxane fluid bearing a small percentage of mercaptoalkyl radicals and a curing agent comprising a 1,1'-oxy-bis-(1-methyl-1-silacyclopentene) are disclosed.  When applied to a substrate and exposed to energetic radiation, these compositions rapidly cure to provide a coating on the substrate that releases aggressive adhesives.  Advantageously, the coating, when cured with ultraviolet light in air, is essentially free of the obnoxious odor which characterizes the analogous compositions of the art which are cured with only polymethylvinylsiloxane as a curing agent. These compositions are useful as radiation-curable paint additives, coil coatings, textile treatments, inks and the like.

Abstract: ABSTRACT OF THE DISCLOSURE         Beverage containers are commonly made with a ring at the top of the can for pulling a knock-out from the can top to provide a discharge opening through which a person can conveniently drink the contents of the can, or pour them into a glass or cup.  The can top gathers dust and other contamin-ants that are a health hazard. This invention locates the dis-charge outlet at the bottom of the can and in a recessed com-partment, and prevents contamination by closing off access to the can bottom by a shelf or other surface on which the can rests, so that the can itself acts as a shield to protect the discharge outlet area from contaminants.

Abstract: Non-throttling Manually Reciprocated Plunger Pump for Consumer-Type Liquid Dispensing Containers Abstract of the Disclosure There is disposed a non-throttling, anti-leak, manually reciprocated, plunger pump for attachment to a consumer-type liquid dispensing container to provide drip-free dispensing of liquid therefrom.  The pump has a hollow-stemmed skirted plunger which is reciprocable in a pump chamber to draw liquid through an inlet into the chamber from a container, and to discharge it from the chamber to atmosphere through the hollow stem of the plunger.  A check valve is positioned in the chamber inlet to allow liquid to enter but prevent its return flow.  A differential force-actuated control element is nested in the plunger, for reciprocation therewith but having capability for axial movement independently thereof.  The control element includes valve means for blocking discharge through the plunger stem and the valve is normally biased to blocking position.  In addition the control element cooperates with a fitment or body insert at the inlet end of the pump chamber to provide telescopingly cooperating cylinder and piston members which are engaged throughout full reciprocal travel of the plunger and control valve.  The fitment includes separate passages for venting the cylinder/piston combination to the interior of the container through an aperture in the wall of the pump housing, and fox communicating the pump chamber with the fluid inlet and dip tube of the pump housing.  The arrangement facilitates quick priming, and good maintenance of prime once established, of the pump.

Abstract: ABSTRACT OF THE DISCLOSURE                  An improved high-voltage, single-shot circuit-protector device, having fuse-like characteristics, and having a chemical operating mechanism, is provided to protect, at low-cost transmission-line circuits.  The device contemplates the use of a single-pressure puffer-interrupter having a driving piston attached to the movable contact structure and operated by chemical operator having an explosive element.  Also, the aforesaid device is self-contained and self-operable, utilizing a current-transformer, which triggers a self-contained static control circuit, the latter effecting the "firing" of the explosive element of the chemical operator to thereby generate gas pressure very quickly, and thus effect opening operation of the contact-operating piston and the attached movable contact structure.             For repetitive use, a manual reset lever is provided, being capable of manual hook-stick operation, and the chemical operator element is replaceable, being also capable of manual hook-stick replacement by service personnel.

Abstract: P.F.-593 ABSTRACT OF THE DISCLOSURE A nonwoven hospital sponge material has been provided comprising a layered fabric having an inner core of a substan-tially hydrophilic material disposed adjacent at least one outer or surface layer or between a pair of outer layers of a substantially hydrophobic material, said sponge material being bonded by passing the material through rolls engraved in a pattern of lands and grooves in such a way that a repeating pattern of three degrees of compression are imposed therein high compression, intermediate compression and, little or no compression.  A nonwoven fabric bonded in this manner becomes more absorbent, loftier, has good surface integrity and does not adhere to the wound surface, when the nonwoven sponge material is then compacted subsequent to the bonding step.          This thusly constructed, rather lightweight nonwoven material, produces a relatively inexpensive and disposable hospital sponge and dressing material having all of the desirable features of the more expensive woven materials commonly used today.

Granted: 1982-02-02
Abstract: ABSTRACT OF THE DISCLOSURE            A process for the preparation of 2-mercaptobenzothiazole is disclosed.  In a first embodiment the process comprises heating a reaction mixture comprising nitrobenzene and hydrogen sulfide in a molar ratio of from about 1:3 to about 1:6, respectively, to a temperature from about 100 to about 170°C, for a time sufficient to substantially reduce the nitrobenzene.  Subsequently, the resultant product mixture is reacted with from about 1 to about 3 mol equivalents of carbon disulfide, based on the weight of the originally present nitrobenzene, at a temperature from about 200 to about 300°C for a time sufficient to convert at least a portion of the reactants into 2-mercaptobenzothiazole.  Preferably, the water of reaction formed by reacting the nitrobenzene and hydrogen sulfide is removed prior to reacting the resultant product mixture with carbon disulfide.  In an alternative embodiment, the process comprises reacting a mixture comprising nitrobenzene, hydrogen sulfide, and carbon disulfide in a molar ratio of about 1:3 to 6:1 to 3, at gradually increasing incremental temperatures which are above about 100°C and below about 170°C until the nitrobenzene is substantially reduced.  Subsequently, the temperature is increased to at least about 200°C for a period of time sufficient to convert at least a portion of the reactants into 2-mercaptobenzothiazole.
