Title: Reversible hydro-mechanical transmission for vehicle - has hydromotor output combined with mechanical gear train via differential and couplings
Inventor: SCHEUERPFLUG HANS
IPC: F16H47/04
Filed: 1978-07-04
Abstract: The hydro-mechanical transmission comprises a first, mechanical, transmission gear train, a second, hydraulic reversible train and a differential with its first member coupled to a shaft. The second member is coupled to the hydraulic motor and the third with the output shaft. Purely hydraulic or hydro-mechanical transmission is selected through a coupling.

Title: Stretched swimming pool type roofing sheet - includes elastic cross struts fixed to form support arch
Inventor: STEPHAN HANS-ALBRECHT
IPC: E04H4/10
Filed: 1978-11-11
Abstract: A length of foil sheet is fitted with parallel transverse support struts for stretching it when spread out, in the provision for roofing over a surface, esp. a swimming pool. The struts are elastic, and are fixable in a stretched position forming a supporting arch for the length of foil, at least across its length. They may be housed in an elongated pocket in the foil, while a much wider pocket at the side serves to accommodate a heat-insulating layer. This enables the length of sheeting to be stretched in an arch shape above the area being covered.

Patent DE-2925912-A1 (DE)
Title: Open=end spinning machine - having exhaust channel in rotor cover connecting rotor with surrounding vacuum chamber
Inventor: STAHLECKER FRITZ
IPC: D01H4/08
Filed: 1979-06-27
Abstract: The spinning rotor of an open-end spinning machine is mounted inside a housing within which a low pressure is maintained by means of a suction line from an exhaust fan. The removable lid of the housing, which also covers the open side of the rotor, has a channel connecting the inside of the rotor to the surrounding low-pressure space, to produce the fibre-transport air-stream into the rotor. With this arrangement, the air stream is not dependent on the form and fit of rotor and cover, and not sensitive to small deviations in the fit. The machine is easily adapted to accommodate different sizes of rotor. Maintenance is not hindered, since the suction line is not connected directly to the housing lid.

Title: Fibre-reinforced plastics moulding esp. of complex shape - produced with melting male half-mould to improve bonding of stiff fibres
Inventor: JONES WILLIAM RAYMOND
IPC: B29C70/44
Filed: 1980-03-14
Abstract: A method of making a composite, fibre-reinforced plastics particle uses a plunger or male half-mould and concave or female half-mould. The plunger is of material of low melting point and is coated with a layer of impermeable elastic material, onto this a layer of fibres is placed or wound, with either pre-impregnation or subsequent application of plastics. This assembly is then placed in the concave mould and the temp. is raised to melt the plunger, pressure being maintained upon the fibre- reinforced plastics material by the expansion of the plunger. The temp. is maintained until the plastics has at least pre-hardened. The plunger is of low melting point material as above and is coated with impermeable elastic material, then with absorbent fabric, followed by a performated separating layer, onto this separating layer the fibre-reinforced plastics cpd. is placed or wound as before and the whole assembly introduced into the concave mould and heated as above. In particular for the prodn. of complicated three-dimensional composite mouldings with fibre reinforcement. The use of a plunger half-mould which can melt away enables comparatively stiff fibre reinforcement to be used, without risk of parts of the fibres not being properly anchored or embedded in the plastics.

Title: Changeover of subscriber line to common service channel - by subscriber dialling own number as connection selection code
Inventor: VOIGT WOLFGANG
IPC: H04M3/51
Filed: 1980-04-11
Abstract: The application is to automatic telephone systems in which a subscriber can choose to be connected to a common service channel, typically for providing an automatic answering service. The device is an extension of an already known system providing this service. An electronic control unit (B) is added to the subscriber terminal equipment. It contains a receiver (E) for dialled numbers which are then evaluated (AW) against a stored number (SP). The store typically contains the subscriber number, and the electronic unit output (2,4) is arranged to connect the subscriber instrument (TAL) input to the answering service channel (SAS) if the subscriber dials his own number. In the reverse direction, a similar process applies. To restore calls to the subscriber extension he again dials his own number and the electronic unit (B) orders the reconnection.
