Title: Power supply for loudspeaking telephone - has delay circuit blocking receiving amplifier when loudspeaker amplifier is on
Inventor: FORDAN GUENTER
IPC: H04M1/60
Filed: 1979-08-30
Abstract: The power supply is for a loudspeaking telephone station, where the speech circuit contains a receiving and a transmitting amplifier. The two amplifiers are regulated by a control circuit. The supply voltage is derived from a double Graetz bridge with a bridge rectifier with common branches for the two bridges. There is a delay circuit (V) which blocks the receiving amplifier (EV) when the loudspeaking amplifier is switched on. The receiving amplifier is blocked until a second capacitor (C2) has been charged.

Title: Bolted shaft fixing for hub sleeve - uses radial compression of clamp ring with external taper also providing location
Inventor: WINCKELHAUS WERNER
IPC: F16D1/095
Filed: 1979-10-20
Abstract: The hub sleeve (1) is secured on a shaft (2) by radial compression. A clamp ring (3) whose outside diameter has two opposite tapers (8,9) locates two flange rings (6,7) on its tapers. Tie bolts (11), equally spaced on the flange rings, are used to pull the two flange rings together. The internal tapers on the flange rings thus produce a radially compressive force on the clamp ring tapers as they are forced up the tapered ring sections.

Title: Signal transmission path monitor - has pilot signals transmitters at several points along transmission path, whose signal have different frequencies
Inventor: STACH MANFRED ING GRAD
IPC: H04B3/46
Filed: 1980-05-13
Abstract: The monitoring device has pilot signal transmitters for feeding their signals into the transmission path. At the end of the latter each pilot signal is received by a monitor, checking its amplitude. At several points of the transmission part (LV1-LVn) are incorporated pilot signal transmitters (PS1-PSn). Their signals have different frequencies. The path end monitor (PE,PM) displays the amplitudes of the received pilot signal. Pref. the monitor has an image screen for displaying the amplitudes as rod diagram. The transmission path may contain several power amplifiers, each connected to a pilot signal transmitter. Since the carrier frequency technique it is a common practice to transmit pilot signals together with operational signals, the monitoring system provides a simple arrangement for checking the transmission path and/or for detecting a defective section.

Title: Modular multiple pole load separating switch - has blocks forming switching chambers closed one side to contain ionised gases
IPC: H01H33/02
Filed: 1980-10-14
Abstract: The multiple pole electrical load disconnecting switch built up in sections on the modular principle, has a flat block (4) housing the components for each pole, forming a switching chamber (30). This is open one side and closed by a partition at the other side to prevent the escape of ionised gases. Down one edge of the closed side is a groove into which fits a rib (36) projecting from the edge of the open side. Screws which lock the housing sections together, pass through tunnel shaped channels (26,27,28) at right angles to the junction plane. Two channels (27,28) terminate in flanged rims at the end towards the open side, to fit into corresponding openings on the closed side. The moving operating arm is connected by spherical contact surfaces to a fixed connection (s) projecting outwards, using embossed parts on the arms of this moving member.

Title: Signal line fault monitoring circuit - monitors voltages across resistors coupling auxiliary voltage source to each line
Inventor: BEYER KLAUS-JUERGEN ING GRAD
IPC: G08C25/00
Filed: 1980-11-04
Abstract: The signal line monitoring circuit uses an auxiliary voltage source of opposite polarity to the voltage supply and coupled to each of the signal lines via an identical protection resistance. These have a relatively small ohmic value in comparison to the resistance connected in parallel with the switching contacts incorporated in the signal lines. The voltage drop across each protection resistance is monitored to verify the state of the lines. The voltage across each protection resistance is fed to an assigned threshold switch followed by an electronic switch coupled via a resistor to one terminal of a further voltage source and via a third electronic switch to the other terminal of this voltage source. A comparator provides a fault signal in response to the voltages at the junction between each first electronic switch and the associated resistor.

Title: Annularly hinged casing for pressure vessel - surrounds closely for protection against bursting
Inventor: HANDEL HUBERT
IPC: B01J3/00
Filed: 1980-11-12
Abstract: A protective casing for a pressure vessel, esp. a cylindrical container with domed ends, closely surrounds the vessel with contacts only at limited sreas, and is formed with one or more axial hinge-like joists extending the full length of the casing. These joints connect to sections of a cylindrical main body whose domed top and base are each in one piece. If the internal pressure vessel bursts, the casing provides protection against shock-wave and flying fragments. The pressure vessel in normal use is still readily accessible for inspection and testing.

Title: Method and apparatus for utilising electrical energy produced outside peak consumption times
Inventor: ECKERLIN PETER DIPL CHEM DR RE
IPC: F24D11/02
Filed: 1981-09-12
Abstract: The electrical energy produced outside peak consumption times is utilised for combined and continuous generation of cold and heat, water, ammonia and an aqueous solution of ammonia being used as working fluids (working media) and the cold removed to a cooling brine being generated, outside the peak consumption times, by  evaporating the ammonia from the solution at low pressure, dehydrating the ammonia vapour and liquefying it with the aid of electrically operated compressors (Ka, Kb), using the heat generated in the process partly for driving off the remaining proportion of the ammonia from the depleted solution and partly removing it as waste heat or alternatively rejecting it to process water (service water) and thus utilising it further, the water and the liquid ammonia being stored for the peak-consumption time, during which the cooling brine has the heat extracted from it by evaporation of the ammonia at from 1 to 2 bar, the ammonia vapour is brought into contact with water in which it dissolves,  the heat liberated in the process is supplied to hot process water, and the resulting aqueous solution is stored until it is processed outside the peak-consumption time. <IMAGE>

Title: Hand-operated bell, in particular for a bicycle
Inventor: GUIDOLIN VALENTINO
IPC: B62J3/00
Filed: 1982-01-09
Abstract: The invention relates to a hand-operated bell, in particular for a bicycle. Known bells have a manual lever and a drive segment which is usually integral with the latter and whose toothing interacts with a gear wheel and which, via the latter, sets in rotation the clapper arranged in the centre of the lower part. The number of moving parts to be mounted and the rest of the drive construction result in a relatively large degree of technical expenditure. This can be reduced according to the invention if the drive segment is fixed to the lower part and if the clapper is rotatably mounted on a part connected to the manual lever. The transmission of force between the drive segment and a rotary pin assigned to the clapper can, inter alia, also be constructed in such a way that the clapper can have the shape of a single-arm rocker whose drive direction changes repeatedly during a swivel movement in the same direction. Furthermore, a greater impact strength of the clapper can also be achieved.
