Patent DE-2716328-A1 (DE)
Title: Two stage valve unit for boiler feed water control - has operating sequence opening first and second valves and feed water pressure control
Inventor: HETZ HEINZ K
IPC: F16K1/36
Filed: 1977-04-09
Abstract: The time sequence valve arrangement (12) has inlet (16) and outlet (18) apertures with first (20) and second valves (22) controlling the flow of feed water from the inlet to the outlet. The first valve (20) has a surface section which remains in connection with the inlet in such a way that the feed water pressure on the inlet side of the valve arrangement closes the first valve (20). The second valve has a section which is in sliding engagement with the first valve, and this section has a surface in contact (12) with the inlet in such a way that the feed water pressure on the valve arrangement inlet side only acts on this sectional surface, producing a pressure which opens the second valve. No feed water pressure opposes this pressure force trying to close the second valve. An operating yoke (10) is connected to both valves, initially opening the second and finally the first valve (20) and which produces a force keeping the second valve in its closed position.

Title: Telephone junction box for portable appts. connection - has stationary contacts opened by plug via stirrup shaped bridge whose shanks have end springs
Inventor: ACKERMANN HANS GERT
IPC: H01R13/703
Filed: 1977-07-16
Abstract: The telephone junction box has stationary rest contacts for disconnecting of subsequent junction boxes, which are opened via stirrup-shaped bridge by plug pins. The bridge shanks press against the sprung contact strips of the rest contacts. At least one of the shanks (8, 9) of the bridge (7) carries on its free front side a spring (11). If the junction box is of eight-pole design it has two rest contacts and both shanks of the bridge are fitted with compression springs. The front sides of the shanks may have blind holes (10) for insertion of the compression springs. In such instance the last turn of the compression spring is of larger diameter and thus clamps the spring in the hole.

Title: Automatic dead reckoning navigator and steering aid - uses magnetometer and A=D converter circuit connected to speed-distance recorder
Inventor: KRAMER GUENTER DIPL PHYS
IPC: G01C21/12
Filed: 1977-12-09
Abstract: The dead-reckoning navigator is designed to provide dead-reckoning information for any curved track automatically. A twin-axis magnetometer (2) is suspended in a gimbal (1) and produces two analogue signals (1, q) which are proportional to the projections of the Earth's magnetic field on the vehicle's longitudinal or transverse axis. Pulses from a speed/distance recorder (3) are fed with those from the magnetometer to a dual-slope type A/D converter (5). Three counters sum the separate components (6). The variation in the magnetic field is corrected for (4) and a reference signal produced. The magnetometer is fitted with adjusters to compensate for inherent and induced stray fields. An auxiliary unit gives the vehicle speed and course deviation.

Title: Injection-moulding warp-resistant plastics lettering stencil - by charging cpd. to mould from opposite sides to allow thorough venting
Inventor: FISCHER ERNST
IPC: B29C45/34
Filed: 1978-01-05
Abstract: In mfr. of a plastics stencil or template for lettering and similar indicia, the injection-moulding technique is used. In order to minimise risk of dimensional instability of the finished stencil (esp. warping) caused by stresses arising from uneven compaction of the moulding cpd. during the injection step, such injection is effected at least once from the direction of one of the longitudinal edges of the intended stencil into a mould cavity. At the same time, moulding cpd. is also injected from the other edge, the injecting sites being sufficiently apart that the air displaced by the injected cpd. can escape along each opposite edge.
