Patent DE-3830828-A1 (DE)
Title: Shock absorber for the damping of sequences of movements
Inventor: KUEHLE WALTER DIPL ING
IPC: F16F9/46
Filed: 1988-09-10
Abstract: A shock absorber is equipped with one throttle valve each for basic and auxiliary damping for separate adjustment of the damping force in a tensile and compressive direction. In the device according to the invention, the adjustable parts of the two throttle valves are designed in the form of valve slides (54, 55) and directly incorporated in a piston (8) of the shock absorber. This results in an especially simple design of the shock absorber. The device serves for the damping of relative movements of two masses, especially in sprung wheel suspension systems of vehicles. <IMAGE>

Title: Process for the parallel generation of silicon tetrafluoride and sulphur hexafluoride
Inventor: DOETZER RICHARD DIPL CHEM DR
IPC: C01G43/06
Filed: 1988-12-07
Abstract: A process is provided for the parallel generation of silicon tetrafluoride and sulphur hexafluoride, in which elemental silicon is reacted with sulphur vapour at temperatures above 600@C to give silicon sulphide, this is purified by sublimation, finely milled and reacted at temperatures between 300 and about 550@C with depleted uranium hexafluoride, converted into the gas phase, in accordance with the equation  SiS2 + 8 UF6 @ SiF4 + 2 SF6 + 8 UF4 The heterogeneous reactions, which are preferably to be carried out in a fluidised-bed furnace, give highly pure products because of the high purity of the starting material. An additional advantage arises from the fact that in the novel process using depleted uranium hexafluoride and waste silicon from semiconductor manufacture, two hitherto unutilised "waste materials" readily available in large amounts can be utilised (valorised).

IPC: C03B37/029
Filed: 1990-03-05
Abstract: Equipment for scaling a heated cylinder against reactive gas entry in a furnace includes an elastic sealing ring which is fused by screwing a removable flange onto a fixed flange of the furnace and which prevents mixing of protective gas in the region of the furnace with reactive gases outside the furnace. The novelty is that (a) the sealing ring (2) consists of felt, pref. graphite or ceramic felt; (b) pressurised protective gas is passed through most of the furnace; and (c) the protective gas flows out through the furnace flange (6) via passages (10) of cross-section and/or number corresp. to the gas throughput. The felt ring (2) is pressed against a flange (6), fixed to the furnace lid (4), by a removable flange (3), the fixed flange having radial passageways (10) which determine the gas flow through the furnace. The protective gas is pref. a noble gas (mixt.), but particle-free air may be used. USE/ADVANTAGE - The equipment is useful for sealing tubes being heated in a furnace, esp. a collapsed preform tube being drawn to glass fibre in a drawing furnace. It provides complete prevention of reactive gas (e.g. air) entry into the space between the tube and the furnace.
