Title: Shaft end joining equipment - has axial holders formed on clamping mechanism
IPC: F16D1/05
Filed: 1979-07-24
Abstract: The equipment joins aligned shaft or pipe ends,having a clamping mechanism with a first cone ring whose cylindrical peripheral face bears against the pipe or shaft, and a second cone ring working with the first and whose cone face is at the same angle. Axial clamping screws move the rings in relation to each other, the cylindrical face of the first one being pressed against the shaft etc. Holders at intervals round the periphery and coupled together in the axial direction engage in peripheral grooves in the shaft ends.

Title: Regeneration of Rochow contact mass - by roasting with gas contg. oxygen before reuse in alkyl-halo-silane synthesis
Inventor: MAAS JOACHIM DIPL CHEM DR
IPC: C07F7/16
Filed: 1979-08-17
Abstract: Regeneration of spent contact masses from the Rochow synthesis of alkylhalosilanes is effected by roasting with an O2-contg. gas. The process esp. applies to carbon-contaminated contact masses from the synthesis of methylchlorosilanes by contact of MeCl with opt. promoted Si/Cu particles. The regenerated masses convert MeCl with high selectivity for dimethyldichlorosilane (DDS). Regeneration is pref. effected in a fluidised bed at 200-400 deg.C using a gas with a lower O2 partial pressure than air (esp. a mixt. of O2 and N2). In a prefd. process, regeneration is effected in situ in the Rochow reactor. The regenerated mass can opt. be doped with fresh Cu and promoter (e.g. Zn, ZnO, Cd, CdCl2 or Al) before being re-used in the Rochow process.

Inventor: ENGA BERNARD EDVARD
IPC: B01D53/94
Filed: 1979-12-13
Abstract: Energy is recovered from a flowing gas stream by injecting a fuel continuously into it to give a stoichiometric proportion of fuel to available O2. The resulting mixture is then fed into a heat exchanger. This exchanger has elements formed from plates welded or otherwise fixed to its surface. The surfaces of these plates are covered with a catalytic metal pref. Pt, Rh, Ru, Pd and/or Ir (alloy) laid on a substrate of refractory inorganic material such as alumina. A catalytic oxidn. of at least part of the fuel occurs and the heat released is removed by the exchanger. A gaseous or liquid fuel can be used. The catalyst can also contain a second metal such as Ti, Va, Cr, Mn, Fe, Co, Ni, Cu, Zu or rare earth metal. The system has the additional advantage that polluting impurities can be removed by the process.

Title: Magnetometer with digital display - uses pulse integration and has premagnetising and induction coils on single core
Inventor: LUEHR HERMANN DR
IPC: G01R33/04
Filed: 1980-11-22
Abstract: The magnetometer uses a probe with a magnetisable core and two coils, one producing a premagnetising field which is periodically driven into core saturation and the other producing the induction voltage via the core induction. Part of the induction voltage is integrated to produce a digital value of the measurement field strength or field gradients which can be easily displayed, recorded and processed remotely free from transmission path disturbances and non-linearities. The inducting voltage is integrated over known intervals. Variations in the induction voltage at the integrator caused by a field acting along the probe axis produce an integrator output proportional the field being measured. The digital circuitry enables economical measurement value indication.
