Filed: 1994-03-31
Abstract: The sleeve-like valve body (40) consisting of elastomeric material is arranged in the valve space (14) enclosed by the housing (10). The sleeve-like valve body (40) is fastened on the housing (10) by means of its fastening end (44) and its flow channel (42) is connected in terms of flow to the inlet opening (24). By means of its central section (50) which spans the ventilation opening (38), the valve body (40) rests against the ventilation valve seat (56) formed on the housing (10). The central section (50) is adjoined by a bead (52), which is adjoined, on the other side, by the end section (54), which rests against the valve seat element (60) under pre-stressing. With water flowing in the flow direction (S) and with the same pressure at the inlet and outlet sides, the valve body (40) resting on the ventilation valve (56) prevents water from flowing out through the ventilation opening (38). With a subatmospheric pressure on the feed side, the central section (50) is raised from the ventilation seat (56) in order to ventilate the outlet opening (28). <IMAGE>

Inventor: DAVIS LEO W
IPC: F16F9/46
Filed: 1991-12-06
Abstract: A vehicular suspension system incorporates, at each wheel (14), a liquid spring (12) which internally utilizes a compressible liquid to generate spring and damping forces that yieldingly resist vertical wheel deflection relative to the vehicle frame. The liquid spring includes a dual piston assembly (36) which divides a main cylinder into bounce (38) and rebound (40) chambers. A rotary metering valve (80) is interposed between the bounce (38) and rebound (40) chambers for controlling the flow of compressible liquid from one chamber to the other during bounce and rebound. The dual piston assembly includes a tubular piston (48) having a modulation chamber (52) coupled in flow communication with the bounce chamber (38). The spring and damping characteristics of each liquid spring are computer adjusted during vehicle operation by modulating the bounce chamber pressure in response to sensed variations in various liquid spring and vehicle operating parameters.

Patent CA-2136165-A1 (CA)
Inventor: STRAUBINGER WERNER
IPC: F24F3/16
Filed: 1994-11-18
Abstract: In a process and installation for removing solvent vapor from exhaust air sucked from a working space, the air is fed to at least two parallel activated carbon adsorbers. Each adsorber can be switched to and fro between a charging mode in which it adsorbs solvent vapors from the exhaust air flowing through the adsorber, and a regeneration mode in which it is separated from the flow of exhaust air and flushed with water vapor and desorbed. To save energy and to reduce environmental pollution, at the end of the regeneration period each adsorber has a drying phase in which exhaust air from the working space flows through the adsorber, the air thereafter being fed to an adsorber which is operating in the charging mode. In the periods in which an adsorber is operating in the charging mode, it firstly has an initial phase followed by a main phase wherein air flows from adsorbers which are in the main phase are returned directly into the working space while the air flow from an adsorber which is in the initial phase is kept separate from the first-mentioned air flows.

Title: Monolithically integrated, tunable resonant circuit and circuit arrangement formed therefrom
Inventor: SCHMIDT LOTHAR
IPC: H03H11/46
Filed: 1994-06-28
Abstract: A circuitry arrangement for a resonant circuit that may be completely monolithically integrated and electrically tuned has a differential amplifier stage with two transistors T1, T1' fed by a constant current source I0 that are differentially loaded at their collectors by a voltage-dependent capacity and inductively loaded in relation to the circuit mass by a pair of emitter followers T2, T2' with electrically adjustable impedances that act upon the base. In order to implement the electrically adjustable impedances, transistors with associated resistances are provided (for example a pair of emitter followers T3, T3 with base pre-resistances R1, R1') which may be adjusted by control currents (for example I1, I1'). The voltage-dependent capacity is implemented by transistors T4, T4' whose short-circuited emitters and collectors are connected so that the circuit node thus obtained is applied to the circuit mass through a voltage source U1. This circuit arrangement may also be used in a controllable oscillator by interconnecting two resonant circuits in a loop. The output signal of the first resonant circuit is used to control the second resonant circuit and the output signal of the second resonant circuit is inverted and used to control the first resonant circuit. In this way, two signals may be tapped at the outputs of both resonant circuits. The frequency of said signals may be varied by a control voltage and their frequency-independent phase difference equals .pi./2. A particularly advantageous implementation of such an oscilla-tor is obtained by decoupling the output signals of both resonant circuits through two identical output driver stages.
