Patent DE-4112473-A1 (DE)
Title: Domestic gas ball stopcock with elastomer, e.g. PTFE, seals - comprising seal-carrying rings making sec. seal by sealant inflating above 100 deg.C stable to 650 deg.C to prevent leakage in case of fire
Inventor: LAYER WOLFGANG
IPC: F16K17/38
Filed: 1991-04-17
Abstract: In a ball stopcock seal, elements (22) consist of high-temp. resistant carrying rings (41, 42) with elastomer (SIC) inserts (47), pref. of PTFE, seating on the ball (14). An annular groove on the back side of rings (41, 42) is filled with a sealing material (49) which inflates at a temp. above 100 deg.C and is temp. resistant up to 650 deg.C. USE/ADVANTAGE - Domestic stopcock for gas supply. Retains the usual good sealing and easy movement at normal temps.; in the event of fire, the sealing material inflates (49) before the PTFE softens at about 250 deg.C, forcing the heat resistant rings (41, 42) into direct contact with the ball to maintain the seal. This avoids gas leakage, which could cause a gas/air mixt. leading to a space-explosion.

Title: Plastic moulding press with several injection pistons - in which each is connected via an adaptor to compensating pistons which moves up at cycle end to attain full pressure
Inventor: PLOCHER WERNER
IPC: B29C45/02
Filed: 1992-08-21
Abstract: A plastic moulding press has several injecting pistons coupled via an adaptor to a common drive. The rear end of each piston rests against a compensating piston and moves between fixed stops in the adaptor. During injection the injection pistons remain against the rear stops for the majority of the cycle and full injection pressure is attained at the end of the cycle by moving the compensating pistons forward in the fixed adaptor to force the injection pistons against the forward stops. Pref. a pressure sensor is positioned between the injection and compensating pistons and is connected to a data and control unit which controls cycle pressures. A further pressure sensor is mounted in the surface of the injecting piston. Each compensating piston is operated by a hydraulic circuit with a spindle drive piston driven by a stepper motor. In an alternative version the compensating piston is pushed against a stop by a coil spring when the piston is unloaded. When the injection pressure reaches a max. value the compensating piston draws back against the spring force until reaching a stop. USE/ADVANTAGE - For prodn. of plastic components, esp. semiconductor switching housings. Ensures complete filling of cavities and enables a pressure limit to be attained at the end of the cycle.

Patent DE-4237547-A1 (DE)
Title: Telefax or colour television image coding system
Inventor: DIRR JOSEF DIPL ING
IPC: H04N7/24
Filed: 1992-11-06
Abstract: The coding system shortens the transmission time for black and white digital or numeric longitudinal coding, by using the same codewords for both black and white and for different numbers or characters, with the input sequence of black and white used as the discrimination criteria. When several successive white lines are coded, the transmission time is reduced further by providing the coded number of white lines before or after the white line codeword.During gray coding the gray stages or binary codewords are sub-divided, with deliberate redundancy where characters occur successively, with subsequent transmission in the same manner as the white lines. The transmission time is reduced for colour image transmission by code multiplexing, with the PAM coded information DC biased. The sum alternating current thus varies in phase by up to 90 degrees.

Title: Injection-moulding machine
Inventor: HEHL KARL
IPC: B29C45/66
Filed: 1993-03-20
Abstract: An injection-moulding machine has a machine foot (10), a fixed and a movable platen (12) and also a supporting plate (13), which bears a closing mechanism (S) and is movably connected to the fixed platen (11) via at least one force-transfer element, which substantially absorbs the forces occurring when the mould is closed. The fact that the force-transfer element is designed as a separate deforming element (bow 14), deformable by the stresses, and that the supporting plate (13) is mounted on the machine foot (10) movably in the closing direction achieves the effect that the deformations occurring during the closing operation are largely directed away without influence on the machine foot, without adversely affecting the mould parallelism (Fig. 1). <IMAGE>
