Title: Electrical primary element whose hermetically sealed housing has a weak point
Inventor: BECKER WOLFGANG
IPC: H01M2/02
Filed: 1987-07-03
Abstract: A weak point (4) which is incorporated by stamping in the housing wall of an electrical primary element and has a web-shaped profile runs along that edge of either the cup part or the cover which in each case forms the transition from the casing part (2) of the housing to one of its ends (1). However, such a weak point does not extend over the entire circumferential length of the housing edge, but is preferably interrupted at two mutually opposite points, with an unchanged wall thickness, corresponding to the contours (5) and (6). These points connect the wall material of the adjacent weak points to the intact housing wall and thus result in the weak points only tearing open and cutting at a bursting pressure which can be defined by the remaining wall thickness, but not being blown off. <IMAGE>

Patent DE-3735011-A1 (DE)
Title: Circuit arrangement for temperature compensation
Inventor: DENNERLEIN LUDWIG
IPC: H03L1/02
Filed: 1987-10-16
Abstract: For the temperature compensation of an oscillator, it is known to store a correction value associated with the respective temperature in a read-only memory. This value is used for controlling the frequency of a voltage-controlled oscillator (VCO). Due to ageing-related frequency deviations of the oscillator, the stored correction values will deviate from the correction values actually required in the course of time. The proposed circuit arrangement is intended to ensure the temperature stability of an oscillator over a long period of time. For this purpose, a non-volatile random-access memory and a control circuit is provided which is connected to a reference element. Whenever it is necessary to form a new correction value, this value is entered instead of the old correction value in the correction value table. Main oscillators for mobile radio stations.

Title: Antenna arrangement
Inventor: MOENICH GERHARD PROF DR
IPC: H01Q1/27
Filed: 1987-11-14
Abstract: A structural shape having two symmetrical antenna sub-surfaces which are insulated from a metallic base surface by a dielectric substrate and are conductively connected to the base surface along a part of their edge is specified for an extremely flat antenna which is arranged, for example, on the fuselage of aircraft. The received voltage which is picked off at the centre point of the arrangement between the two sub-surfaces is connected in a low-impedance manner to that side of a transformer which has only one turn or a few turns, said transformer having a high transformation ratio and its primary being connected to the input of a receiver. A crossed-over arrangement of two sub-surface pairs produces a Watson-Watt-compatible direction-finding antenna.

Title: Machine tool
Inventor: REICHENBACHER WINFRIED DIPL IN
IPC: B23Q1/01
Filed: 1988-05-31
Abstract: Hitherto known machine tools have portal beams which project on both sides above the machine table, as a result of which, on the one hand, additional safety measures are required and, on the other hand, loading is possible only via the front ends of the machine table. In contrast, the novel machine tool is also intended to be accessible from the longitudinal side, otherwise the advantages of the portal type of construction are to be retained. For this purpose, the portal beam (15) projects only on one side (at 71) of the machine tool (1) beyond the machine table (6), whereas it ends on the other side (at 72) approximately at the level of the machine-table limit and is supported by the column (11) correspondingly drawn to the inside. The novel machine tool is especially suitable for short machining operations, the workpieces being mounted and removed simultaneously during the machining operation. <IMAGE>

Patent DE-3826521-A1 (DE)
Title: Device for wetting pack construction materials
IPC: B28C5/02
Filed: 1988-08-04
Abstract: To wet construction materials used in underground mining, in particular to construct roadside packs, a wetting device is used which consists of a pipe length which can be inserted into the supply line. A nozzle beam fitted with a multiplicity of water nozzles is arranged concentrically to the pipe length. The nozzle beam is held essentially by the water feed line passing through the pipe wall of the pipe length. Several water nozzles producing mist zones are arranged in this nozzle beam and in fact are sunk in such a way that they themselves are not exposed to the wear. Thus wetting of the flow of pack construction material from the centre to the pipe wall is possible, as a result of which complete wetting is guaranteed, which is optimised further owing to the fact that a water nozzle discharging in the delivery direction is arranged at the rear end. <IMAGE>

IPC: B62B7/10
Filed: 1988-11-17
Abstract: A clamping pivot joint for holding two members 12, 28 e.g. of a push chair at a selective orientation relative to one another comprises a first coupling element 30 keyed on a bolt 38 and having detent formations 44 arranged to engage with complementary formations 46 on a second coupling element 34 which is journaled on the bolt 38.

Filed: 1989-03-01
Abstract: A process with improved economic efficiency for the catalytic and/or thermal post-combustion of process waste air containing organic compounds in variable concentration by passing the process waste air through a post-combustion zone is characterised in that, above a minimum value of the flow volume through the post-combustion zone, this flow volume is controlled so that the temperature increase of the process waste air in the post-combustion zone remains below a preset maximum value and below 1300 K, and in that the feed air to the post- combustion zone is preheated in such a manner that the post-combustion zone waste air has a temperature within a predetermined range.

IPC: F25J3/02
Filed: 1989-06-15
Abstract: Removal of N2 from natural gas contg. CO2 and N2 in variable concn. occurs by low temp. rectification in several sepn.  stages, in which the CO2-contg. natural gas together with a part of CH4 and opt. higher hydrocarbons as the liq. fraction are removed in a first stage and the gaseous fraction liberated by CO2 is decomposed by further step-wise rectification into N2-and CH4-prod. fractions and the obtd. prod. stream.m preheated and finally evapd. The novelty is that: (a) the liq. CO2-enriched hydrocarbon fraction (I) is partially evapd. in indirect heat exchange with the produced gaseous N2-enriched hydrocarbon fraction (II); (b) a gaseous methane-prod. and a liq. CO2-contg.  hydrocarbon prod. (III) are obtd. by partially evaporating (I); and (c) (III) is compressed before preheating and evaporating by indirect heat exchange with cooling natural gas to raised pressure. USE/ADVANTAGE - Removal of N2 at higher CO2 contents is possible than was before. The presence of C2+ components in natural gas is no longer necessary.
