Abstract: COMPRESSED GAS FILTER ASSEMBLY     Abstract of the Disclosure Assembly for filtering compressed gas having dual desiccant-containing filter units each equipped with pneumatically opened and closed inlet and outlet check valves and a pneumatically opened draim valve so connected to each other and a control valve for alterna-tely receiving and exhausting actuating gas as to cause the inlet and outlet valves to close before opening and open after closing of the drain valve.  Normally, one unit filters while the other is being regenerated in timed cycles under control of the control valve for maintaining an uninterrupted output of filtered gas, but a regulator valve in the actuating gas supply to the control valve prevents the units from cycling and forces both to filter when the pressure upstream or downstream of the assembly is below a predetermined level.           Piping between regenerating valving connected to a filtered gas outlet of each unit and combining a check valve for passing gas freely from and a restricted ori-fice for restricting flow to the unit and applying the restricted flow directly to the desiccant, enables each unit during filtering to supply filtered gas under sub-stantially constant pressure for reverse-flow regenerat-ing and cooling of the desiccant in the other unit. For preventing freezing during cold weather, each unit has its drain valve positioned above the level of its contaminant-collecting sump and the intervening drain pipe both wrapped with a thermostatically controlled heating coil and foam-insulated within protective sheathing from ambient air.

Abstract: ABSTRACT OF THE DISCLOSURE      This disclosure pertains to a vehicular safety device utilizing a fog sensing apparatus for detecting the presence of for immediately preceding the foremost portions of the vehicle. When fog is detected, the braking system of the vehicle is gradually but forcibly brought into play reducing the speed of the vehicle to a preset maximum determined by a governor operated by the engine.  A control wait is concurrently activated which causes the rearmost lamps of the vehicle intermittently to energize, and automatically altering the mode of operation of the headlamps of the vehicle for a time period equal to the continual sensing of fog.

The fountain assembly has a closed, vented reservoir, a fountain means which directs water from the reservoir in an upward stream for drinking pur-poses and provides a barrier to prevent gravitational backflow of water from the fountain means to the reservoir, a weir which provides a large capacity overflow for the reservoir and main-tains a substantially constant water head above the fountain means when an uneven excess flow of water is received by the reservoir, a bowl for receiving water discharged from the fountain means, and a hydrant with a hand operated valve to fill water containers.  All internal surfaces of the fountain assembly are sloped for complete drainage, and a drain assembly extends from the fountain assembly to an anchor point on the well foundation.  Where water purification is required, puri-fication circuit means direct raw water from the base to puri-fication equipment and direct purified water from the puri-fication equipment to the fountain assembly.

Abstract: 986.012 Title:      COMPOSITION AND METHOD FOR PREPARING FOAMS             OF SOLID LIQUESCENT MATERIALS USING SELECTED SOLID PARTICULATE SUBSTANCES     Inventor:   John A. Heinen ABSTRACT OF THE DISCLOSURE     Rigid forms are produced from normally solid but liquescent materials by incorporating certain selected solid particulate substances in solid liquescent material either alone or in combination with conventional blowing agents.  The solid particulate substance is one which acts as a carrier for an entity which will function as a blowing agent when the material is in the liquid state but which will not be released from the solid particulate substance under normal storage conditions.  The solid particulate substance does not undergo physical or chemical change itself to produce a foaming action.  Properties of the foam or cellular structure produced by incorporating solid particulate substances may be varied, by utilizing various particulates, sizes, quantities and procedures, above and beyond those achieved, to impart additional characteristics such as structural strength, surface texture, color, insulative properties, skid resistance and the like.  The composition and method according to the invention have particularly advantageous application in the production of sulfur foams and cellular aggregates produced by adding fluid coke or anthracite coal as the solid particulate substance to molten powdered elemental sulfur.

Abstract: TRANSACTION EXECUTION SYSTEM WITH SECURE ENCRYPTION KEY STORAGE AND COMMUNICATIONS                                  Abstract A transaction execution system having a multiple account data base and a plurality of transaction terminals in communication with the host.  The terminals each include a keyboard, a display, document handling subsystems, a hardware control subsystem, a communication subsystem and a programmable control subsystem supervising the other subsystems.  A user initiates a transaction request by in-serting a card, which may have been issued by any of a plurality of cooperating card issuers or banks, into one of the terminals. The issuer identification number is read from the card, and used to search a table of card format and encryption key data.  If the corresponding format and key data is located in the table, the terminal requests entry of a preassigned personal ID number through the keyboard.  Verification data located on the card by format data from the table is encrypted in response to the key data from the table for comparison with the keyboard entered ID number.  If the corresponding format and key data is not located in the table, the card data is sent to the host, which accesses a master table with the issuer identification number, and communicates back to the terminal the corresponding format and key data located in the master table.  Once the terminal has checked for correspondence between encrypted verification data and the ID number, in response to format and key data from its own table or communicated from the host, addi-tional transaction data is obtained via the keyboard.  Upon command from the host, the host supplied format and key data is purged by the terminal at completion of the transaction, or else retained for future reference.

The bimetal strip has a tripping portion which executes a tripping motion as the bimetal strip undergoes deformation under the effect of heat generated by an excess current flowing through the bimetal strip.          The bimetal strip is formed of two electrically serially connected, oppositely wound bimetal helices each having an outer end constituting the opposite ends of the bimetal strip.  The bimetal strip is affixed to the housing at both of its opposite ends.  Further, the bimetal helices each have an inner end connected to one another by a coupling part.  The coupling part constitutes the tripping portion of the bimetal strip.

The usual oil channel to the conductor ducts through the joint dielectric itself is avoided, as this occasionally represents a point of electrical weakness.

Abstract: 10.1.1979                                   PHN 9156 ABSTRACT:     The invention relates to a shaving apparatus comprising a drivable cutting unit with cutters, each cutter being equipped with a lead cutter which leads in the direction of driving and which is movable relative to the cutter. The lead cutters serve to slightly pull the hairs, so that a better shaving result can be obtained. The distance over which the hairs can be moved is limited by the shape and dim?n sions of the cutter and the lead cutter and by the pro-perties of the hairs and the skin. It is the object of the invention to eliminate this restriction and this leads to a construction in accordance with which each cutter, in addition to the said first lead cutter, is equipped with a second lead cutter which leads relative to the first lead cutter and which second lead cutter is movable relative to the first lead cutter.
