Patent DE-3474597-D1 (DE)
Title: Frequency comparing circuit
Inventor: YAMAGUCHI AKIRA C O PATENT DIV
IPC: G10L19/02
Filed: 1984-11-14
Granted: 1988-11-17
Abstract: According to a frequency comparing circuit of the present invention, there is provided a negative switched capacitor circuit (10) having negative equivalent resistance, the value of which is determined according to the reference frequency and the frequency to be compared, and a positive switched capacitor circuit (20) having positive equivalent resistance, the value of which is determined according to the reference frequency. A constant DC voltage (V) is supplied in parallel to one terminal of the two switched capacitor circuits. The respective terminals of the switched capacitor circuits are commonly connected in order to produce the composite current of both output currents of the two switched capacitor circuits. The composite current is integrated by an integrator (30). Further, there is provided a Schmitt-type oscillating circuit (83). The oscillating frequency signal from the Schmitt-type oscillating circuit is supplied to the negative switched capacitor circuit. The higher level threshold voltage (VH) of the Schmitt-type oscillating circuit is determined according to the composite current of both output currents of the two switched capacitor circuits, thereby adjusting the frequency of the oscillating signal of the Schmitt-type oscillating circuit. The oscillating signal is supplied to the positive switched capacitor circuit. The lower level threshold voltage (VL) of the Schmitt-type oscillating circuit is determined according to the composite current of both output currents of the two switched capacitor circuits. Therefore, the frequency of the oscillating signal of the Schmitt-type oscillating circuit is adjusted.

Title: A rotary atomizer for coating workpieces with a fine layer of liquid material, and a method for operating the said atomizer
Inventor: SMYTHE KENNETH ROBERT
IPC: B05B3/10
Filed: 1984-08-01
Granted: 1989-03-23
Abstract: A rotary atomizer (10) for coating workpieces with a fine layer of liquid material fed at very low flow rates includes a bell-type rotatable atomizing device (12) for dispensing the liquid from an edge (17) in an atomized condition under the effect of centripetal forces. The liquid fed into a tube (21) having an outlet (20) within the bell (12) appears as discontinuous drops (40) at the outlet (20). Air is also fed into the bell (12) via a tube (25) having an outlet (26) disposed adjacent the liquid outlet (20) such that the air jet (41) breaks up the drops (40) and forms a spray (42) directed at the internal wall of the bell (12). The spray (42) coalesces into a continuous film of liquid as it travels on the internal wall of the bell (12) to the discharge edge (17).

Title: Pressure sensor with a resistor
Inventor: DOBLER KLAUS DR ING
IPC: F02B3/06
Filed: 1984-09-08
Granted: 1989-09-07
Abstract: To provide an unyielding support surface for a film-type, typically thick-film resistor (10) made of pressure-responsive resistance material, an unyielding pressure-tight mass of insulating material, for example a melt of glass, ceramic, or suitable plastic, is introduced into a wall portion of a wall element (11) in which a fluid pressure medium, such as high-pressure fluid for injection to a Diesel engine, is retained. The insulating mass is, preferably, formed as a plug element, for example retained within a metal screw which, simultaneously, can form a venting screw for the fuel injection system. One or two electrical conductors (12, 13) pass through the plug element, which if a metal screw, surrounds the insulating mass, the resistance element can extend over the edge of the metal which, then, can form a ground or return connection. The surface of the plug element is either flush with the surface of the wall or, for example, forms a laterally relieved slot extending parallel to the axis of the plug, which slot may be filled with a protective pressure-transmitting compound and covering the electrical resistance element there located, so that the end surface of the screw and pressure-transmitting filler will be flush with the wall (11) confining the pressure medium.

Title: High concentration encapsulation by interfacial polycondensation
Inventor: BEESTMAN GEORGE BERNARD
IPC: B01J13/02
Filed: 1985-06-11
Granted: 1988-09-22
Abstract: This invention relates to a process for encapsulation, and particularly to the production of small or minute capsules constituted by a skin or thin wall of polymeric material e.g., polyurea, polyamide, polysulfonamide, polyester, polycarbonate, or polyurethane, which involves first providing an aqueous solution (continuous phase liquid) containing an emulsifier which is a water soluble, alkylated polyvinyl pyrrolidone polymer which will form a stable oil-in-water emulsion under the process conditions described herein. A discontinuous (immiscible or organic) phase liquid containing a water-immiscible material which is the material to be encapsulated, plus a first shell wall component; is dispersed in the aqueous liquid to form an oil-in-water emulsion. The second shell wall component is added to the oil-in-water emulsion whereupon the first shell wall component reacts with the second shell wall component to form a solid polycondensate shell wall about the material to be encapsulated. The capsules formed may be directly used as in the form of an aqueous suspension.

Abstract: A feed gas is passed to a pressure swing adsorption system, each bed of which undergoes a processing cycle that includes (1) pressurization (2) copurge at upper adsorption pressure, (3) countercurrent depressurization, including, in some embodiments, evacuation to a lower subatmospheric desorption pressure. By recycling effluent gas released upon copurge and countercurrent depressurization for use in the pressurization or the copurge step, the more readily adsorbable component of the feed gas is advantageously recovered at high purity and at high recovery levels. Enriched less readily adsorbable component is also recoverable as coproduct effluent at relatively high recovery levels. The process can be advantageously employed for the separation and recovery of product nitrogen from air.
