Title: Temp.-stabilised oscillator circuit with controlled heating element - detects change of impedance at output of VCO associated with temp.-sensitive measurement oscillator
Inventor: ZWACK EDUARD DIPL ING
IPC: H03L1/02
Filed: 1993-01-29
Abstract: A voltage-controlled oscillator circuit (VCOS) delivering a clock signal (ts) incorporates a temp.-measuring oscillator (MO) whose output is evaluated by an impedance processor (WAE) in the oscillator output connection (AV).

Title: Suspension flow throttling - uses a hollow zone with different cross=section parts for flow resistance to be varied between them
Inventor: BEGEMANN ULRICH
IPC: F15D1/00
Filed: 1993-02-25
Abstract: A fluid flow is passed through a hollow zone which has at least two different cross sections in relation to the flow direction. The flow resistance is adjusted at a throttling section by altering the contour of the transit between one cross-section and the second, different, cross section in the hollow zone. The transfer in the flow path between the two sections is varied in steps, where each section has a constant but different cross-section. At least one rounded section is fitted to the cross-section change-over, at the narrower section, with an adjustable radius in relation to the sharpness of the edge to give a variable flow resistance according to the magnitude of the rounded  edges. USE/ADVANTAGE - The technique gives variable throttle action in a fluid flow in a closed channel, esp. in the suspension flow feed to a papermaking machine and esp. at the stock inlet. The system gives a high effect action with small changes in geometry to reduce the risk of clogging and tangling the fibres.

Title: Lorry with trailer axle which can be moved in the longitudinal direction
Inventor: WIELSCHER BENNO
IPC: B60G5/00
Filed: 1993-08-27
Abstract: In order to improve the ease of handling a trailer whose load surface can be inclined by changing the distance of the axle from the towing vehicle, it is proposed to cause the axle 7 which is attached to a chassis 6 to move backwards by means of a drive element 10, with the aid of which drive element 10 the chassis 6 can be moved backwards into its normal position without moving the towing vehicle. In order to lock the chassis 6 in the normal position a kingpin 14 is used which interacts with a fifth wheel 13. Lateral movements of the chassis 6 on the chassis carriers 2 and vice versa, can be avoided by means of a conical recess 15 at the rear end of the chassis 6, into which recess 15 a conical bolt 16 which is arranged on the chassis engages. <IMAGE>

Title: Device for the disposal of toxic, solid and/or liquid materials, in particular of projectiles which are filled with chemical agents
Inventor: VOLLHARDT FROHMUT DIPL ING
IPC: F23G5/20
Filed: 1993-10-04
Abstract: The invention relates to a device for burning toxic, solid and/or liquid materials, in particular projectiles which are filled with chemical agents. Since the ammunition which is to be burnt may accidently not have been rendered safe in advance, the combustion system must withstand the pressure of at least 40 bar. According to the invention, the combustion is carried out in a unit which is mounted such that it can rotate and consists of a rotating tube furnace 3, a secondary combustion chamber 6 and a waste-heat boiler 9. The said unit is designed to be appropriately pressure-resistant and the rotating tube furnace 3 as well as the secondary combustion chamber 6 are clad in a fire-resistant manner. The operating pressure is produced via a compressor 20, which is connected upstream of the combustion system, and is reduced by an expander 18 which is connected downstream of the entire installation.   <IMAGE>

Title: Mould-filling process for thermoplastic materials, in particular for mixed recoverable plastics materials
Inventor: BECK ERICH
IPC: B29C45/17
Filed: 1993-10-26
Abstract: The production of thick-walled parts from recoverable plastics materials by the intrusion process still essentially suffers from the disadvantages of inadequate surface quality and very long cooling time. To reduce the cooling time of thick-walled parts of thermoplastic materials, liquid or gaseous cooling media are injected into the core of the moulded parts. The injection of the thermoplastic moulding compound, performed at low pressure, results in a good surface finish by being passed along the mould wall.
