Title: Hinged loading ramp for the bottom landings of cage winding installations
Inventor: SCHNEIDER PAUL
IPC: B66B17/18
Filed: 1984-03-01
Abstract: A hinged loading ramp 1 for the bottom landings of cage winding installations is given a substantially simplified design without impairing its operating reliability. It is mounted, in such a way that it can be swung about a fixed, horizontal pivot 2, on the haulage road 5 as a connecting track between the latter and the supporting floors of the hoisting cage placed in front of the haulage road 5. Via a compressed-air drive 13, the hinged loading ramp 1 can be adjusted between a steeply sloping raised position outside the cageway and a horizontal lowered position or a lowered position at a gentle slope in the opposite direction reaching into the cageway, in which case it can be locked in the raised position and in addition has an elastically yielding supporting connection relative to the compressed-air drive 13. The compressed-air drive consists of at least one bellows cylinder 13 sitting near the hinge pivot 2 between a fixed abutment 15 and the hinged loading ramp 1. The bellows cylinder 13 is connected to the source of compressed air via a shut-off valve which is acted upon in the opening direction by the operating pressure of the compressed air but in the closing direction is under the action of an energy accumulator and which, in the event of pressure failure, is automatically activated in the closing direction and shuts off the bellows cylinder 13 to prevent escape of compressed air. <IMAGE>

Title: Process for producing table-tennis balls
Inventor: MELCHIOR KLAUS DR RER NAT
IPC: B29C65/00
Filed: 1984-10-18
Abstract: Various production processes for table-tennis balls are specified to compensate for the disturbances of the isotropic moment of inertia of table-tennis balls, which occur during processes of shaping sheet-like elements and during the joining of a plurality of sheet-like elements, and to obtain uniform stiffness and therefore constant resilience. In addition to a thermal process for homogenising the wall thickness within the sheet-like elements, suitable processes for seam-shaping and also compensating processes are specified with which, by applying additional appropriate correction masses, an isotropic moment of inertia of the table-tennis ball results.
Patent DE-3445918-A1 (DE)
Title: Method and device for controlling catalytic reactions
Inventor: REINERMANN KARL-HEINZ
IPC: C08F4/48
Filed: 1984-12-17
Abstract: In catalytic reactions, interfering substances may be present in the reaction batch, which react more rapidly with the catalyst than the catalyst is able to initiate the catalytic reaction. The method according to the invention reduces the amount of catalyst required to achieve the desired properties of the reaction product. The interfering substances are deactivated directly in the reaction batch by means of the catalyst and the amount of catalyst required for the catalytic reaction is added to the reaction batch immediately afterwards. 
<??>In order to recognise the state, at which the interfering substances in the reaction batch have just completely been deactivated, use is made of the heat of reaction associated with the catalytic reaction. Said heat of reaction is measured with extremely sensitive electrical appliances which are designed for continuous use under operational conditions. 
<??>This method makes it possible to adjust the desired properties of the reaction product in a specific and reliable manner. The method is illustrated, by way of example, for anionic polymerisation.

Title: Valve pre-amplifier
Inventor: LANGE LOTHAR
IPC: H03F3/181
Filed: 1985-03-29
Abstract: A pre-amplifier for audio frequencies is proposed, with a valve-fitted equaliser pre-stage (10), a valve-fitted linear stage (11) and a common power supply unit (48-50) for both amplifier stages. The output of the equaliser pre-stage (10) and a plurality of inputs (14-18) can be connected as required via a multiple switch (31) to the linear stage (11). By means of a switching device which has a switching element (42) in the valve-heating circuit of the equaliser pre-stage (10), the equaliser pre-stage (10) can be connected and disconnected independently of the switching condition of the linear stage (11). Since the valves (19, 26) in the equaliser pre-stage (10) are activated in this way only when required, their effective operating life is increased. <IMAGE>
