Title: Socket end with circular vice - in thermoplastic tubes produced in two thermo-forming stages
Inventor: RIEGEL KARL-HEINZ
IPC: B29C57/02
Filed: 1980-01-17
Abstract: Tubes, made of a crystalline or partly crystalline thermoplastic material such as polyethylene or polypropylene, are fitted with a thermoformed socket and circular nick in two stages. The tube end is heated in an annular heating device uniformly to close to the crystallite melting point and is axially upset to fill out the annular space. In the second stage the upset end receives the final shape in a forming device by a second upsetting axial force. This reduces the number of crystallites and the stress in the tube ends enough to eliminate irregular radial and axial swelling.

Title: Teletype transmission of formatting information - has coded instructions, for formatting, forwarded and stored with continuous tert following
Inventor: STETTEN HANNS NORBERT VON
IPC: H04L13/18
Filed: 1980-05-14
Abstract: The equipment and method is for transmitting formatted text between terminals, primarily teletype machines, in a transmission network. The message is divided into the text layout/format instructions, which are stored in the receive terminal, and the continuous text information which is printed out according to the layout instructions held. The method avoids having redundant time in an on-line transmission by enabling the information text to be a continuous transmission and not a spaced transmission incorporating the layout information of a standard form or document. The equipment operates in half duplex mode receiving signals off line (L) through a hybrid terminating unit (W). The receive terminal has verifying circuitry (Reg1, Dec1, FF1, FF2, FF3) which responds to address codes and switches (GU1, GU2, GU3) the incoming signal either directly through to the receive side (E) of the terminal, into an intermediate store (Ksp) or into the text format instruction store (TBM). The text format store (TBM) has its own address decoder circuitry (Reg2, Dec2) on its write input. The intermediate store (Ksp) has an input from the switching circuitry (GU2) for the text which is then formatted according to the read out into the intermediate store (Ksp) from the text layout stored (TBM) information.

Title: Switch for additional brake lights on motor vehicles
Inventor: WEISENER HERBERT
IPC: H01H35/14
Filed: 1981-06-27
Abstract: A switch for automatically activating additional brake lights on motor vehicles is described, which switch only switches on and allows the additional brake lights to light up when the travel speed is dropping. A lever which is provided with an inertia body is provided, which lever is mounted so as to be easily rotated about a bearing pin and can be moved in an oscillating fashion between stops. By virtue of the inertia body on the lever, speed changes bring about a displacement of the centre of gravity as a result of which the oscillating movement of the lever is triggered. The lever is assigned a trigger switch for the additional brake lights. When speed is dropping, the inertia body at the lever continues to move, due to the power of inertia, in the direction of travel at a speed of travel which remains constant and it rotates the lever about its pivot point towards the trigger switch and closes its contacts. The trigger switch is connected in series with the existing normal brake lights so that this trigger switch is only activated together with the brake pedal.

Title: Circuit for invertors for emergency power supply systems
Inventor: PROSCH TERTIUS A
IPC: H02H7/122
Filed: 1981-07-11
Abstract: A circuit for a limited-power invertor for emergency power supply systems (standby power supply systems) is described, by means of which the power of the invertor is transformed in the event of a short-circuit on the load side in the direction of lower voltage and higher current intensity. The circuit consists of a measurement and control unit which is connected into the load circuit and opens the load circuit via a relay device in the event of a short-circuit, at the same time connects a transformer between the output terminals on the load side of the invertor and, in addition, connects a suitable transformer tap to the load circuit. This results in a multiple of the rated current flowing in the load circuit in the event of a short-circuit. After a predetermined time has elapsed, a timer switches the relay device back into its quiescent position. If the load circuit contains overdimensioned fuses, a counting element cuts off the entire invertor after a limited number of changeover operations of the relay device without any result.
