Title: Multiple nozzle injection moulding machine - has unheated needle valves guided to obviate need for tight tolerances
Inventor: CZESCHNER BRUNO DIPL ING
IPC: B29C45/28
Filed: 1976-03-27
Abstract: Machine comprises a multiple mould and a corresp. multiple injection nozzle unit. In front of each screw inlet to each mould cavity there is a chamber, open to the outside but closed by the hollow nozzle tube applied to the face of the mould to form a seal. A needle valve axially applied under spring force passes through the nozzle tube and the open-ended chamber to close the sprue inlet to the mould. When the injection pressure is sufficiently high, this needle valve is forced backwards against the spring force by the action of the material pressing on its conical forward end, thus causing the valve to open and injection into the mould to take place. Each needle valve penetrates sufficiently far through the sprue inlet to terminate flush with the inner wall of the mould cavity at the sprue side. The hollow nozzle tube surrounding the needle is axially slidable in the nozzle unit. The arrangement enables the principle of a single injection nozzle to be applied without great difficulty to a multiple injection nozzle system. No excessively tight tolerances are required and differential thermal expansion between the mould and the injection nozzle unit does not give rise to problems.

Patent DE-2650153-A1 (DE)
Title: Insulation and sealant for flat or slightly sloping roofs - by fitting insulation panels to form drain channels and applying several layers of polyurethane foam
Inventor: GREGUSCH OTTO
IPC: E04D11/02
Filed: 1976-10-30
Abstract: Flat or slightly sloping roofs are insulated and sealed by mounting pre-fabricated insulating panels (so-called base profiles) on top of the roof structure so that the spacings between them define drain channels. The resulting surface is then sprayed with a thin layer of polyurethane foam. This is followed by one or more applications (depending on the desired thickness of layer(s)) of further polyurethane foam to achieve the intended insulation and sealing. Reliable gapless insulation/seal is achieved even for flat roofs, which are notoriously prone to dedratations by atmospheric precipitation and other weather hazards. The channels ensure quick runoff of rain water or melting snow and ice. The process is relatively inexpensive.
Patent DE-2655379-A1 (DE)
Title: Power steering system requiring smaller steering wheel movements - has combined valve and pump with flow causing pressure difference across throttle to control steering cylinder supply in secondary circuit
Inventor: MUELLER WILLI
IPC: B62D5/093
Filed: 1976-12-07
Abstract: The steering column drives a pump (12) and simultaneously operates a valve (6, 7) both of which are combined in a single unit. The valve opening is proportional to the torque applied to the steering wheel. When the steering wheel is turned, flow of fluid in the primary circuit (17, 18) causes a pressure difference across one of the throttles (41). This pressure difference controls the flow in the secondary circuit, through which a motor-driven pump (22) operates the steering cylinder (30). This system permits a steering ratio requiring smaller steering wheel movements to be used.

Patent DE-2719805-A1 (DE)
Inventor: GOELZ GUENTER DIPL ING
IPC: H02M7/12
Filed: 1977-04-28
Abstract: The object exists for a filter arrangement for a pulse-controlled converter with an impressed current on the DC side and in parallel with whose AC-side input a capacitor is connected of greatly reducing or completely preventing the load, which contains harmonics, on the supplying AC network and resonance effects associated therewith, by a suitable wiring up of the pulse-controlled converter input. This object is achieved by means of a series-path inductance (LF) on the AC side, which inductance is dimensioned in such a manner that, together with the capacitance of the capacitor (C), it defines a resonant frequency which is between the fundamental of the AC current and the pulse repetition frequency of the converter (P). <IMAGE>
Patent DE-2723800-A1 (DE)
Title: DC voltage converter using transistors - has short circuit protection derived from auxiliary winding on output transformer
Inventor: UHLE MATHIAS DR ING
IPC: H02H7/12
Filed: 1977-05-26
Abstract: Protection for a voltage converter using semiconductor elements (T1-T4) is achieved by adding an auxiliary winding (W4) to the output transformer, and using the rectified output voltage of this winding as the voltage source for the semiconductor switching element (T1-T4). The rectified voltage is smoothed in a large capacitor (Cs) and connected to the input power supply through a resistor of high ohmic value (Rs1). If a short circuit occurs across the output the transformer flux collapses. The auxiliary winding voltage therefore drops and the supply to the switching elements will fall to a point where it is impossible for the control oscillator to turn them on.
