Title: Method for introducing samples into a gas chromatograph, and device for carrying out this method
Inventor: BRAZHNIKOV VADIM VASILIEVICH
IPC: G01N30/12
Filed: 1981-08-18
Abstract: The invention relates to gas chromatography, in particular to a method for introducing samples into a gas chromatograph. When samples are introduced, the substances for examination are introduced by means of a sample carrier (2) into the vapouriser (1) of a gas chromatograph, and the vapours thus forming are then transferred into a carrier gas stream. According to the invention, the vapouriser of the gas chromatograph is hermetically sealed only for the period of introduction of the sample after the vapouriser has been physically connected to the sample carrier. The transfer of the vapours of substances for examination from the vapouriser into the chromatographic column takes place via a restriction of constant cross-section downstream of the passage of the vapours of substances for examination into the chromatographic column (3). The device proposed according to the invention has a restriction (15) which is located downstream of the channel (11) for connecting the sample carrier (2) to the vapouriser (1), but upstream of the channel (19) for leading the vapours of substances for examination out of the vapouriser into the chromatographic column (3) and has a constant cross-section. The sample carrier (2) is provided with a sealing element (23) which, for the period of introduction of the sample, hermetically seals the channel (11) for connecting the sample carrier (2) to the vapouriser (1). <IMAGE>

Title: Arrangement for the distance-dependent braking of hydraulic drives with speed control
Inventor: SOMMERSCHUH STEFAN
IPC: F16D57/06
Filed: 1981-08-24
Abstract: The invention relates to an arrangement for the braking of hydraulic drives using a differential pressure valve and a controllable control throttle valve connected to this in series on the inlet or outlet side, which throttle valve is controlled by a linear cam curve. The aim of the invention is to prevent pressure peaks and natural frequency oscillations of the drive caused by these. The object is achieved of producing a brake characteristic with an approximately sinoidal curve, which can be adapted to adjustable constant speeds before braking begins in a limited range by means of an unmodified cam curve. The invention proposes that an adjustable throttle valve be connected in series to the outlet side of the control throttle valve, the outlet of the throttle valve being branched off to the spring-supported side of the pressure governor of the differential pressure valve. The brake curve over the braking distance is determined by the ratio of the area of the throttle cross-sections of the control throttle valve to the throttle valve. <IMAGE>

Title: Method of producing a semiconductor device
Inventor: CLAUSS HERMANN DR
IPC: H01L21/027
Filed: 1981-09-23
Abstract: In a method of producing a semiconductor device, one surface of a semiconductor body is coated with an insulating layer and two openings are made in this insulating layer to produce two semiconductor zones of different depth. Then the first opening is closed again, and to produce the second semiconductor zone, impurities are introduced into the semiconductor body in a preliminary process. After that, the first opening is opened again and impurities are then driven into the semiconductor body through the two openings so that, in the semiconductor body, the first semiconductor zone reaches a smaller final depth and the second semiconductor zone a greater final depth.
Patent DE-3138624-A1 (DE)
Title: Partial winding construction and interconnection in the case of foil windings
Inventor: WALDNER PAUL PROF DR ING
IPC: H01F27/28
Filed: 1981-09-29
Abstract: Windings are in general constructed from copper wires. Because of arrangement difficulties, aluminium windings are used only for large apparatuses, in particular transformers. The arrangement and insulation difficulties are circumvented in the case of the invention in that:   1) The winding is split into several partial windings, which are designed as sandwich windings. The winding material (aluminium) consists of a strip. The insulation can be realised either on the strip (foil) itself, for example by anodising, or by means of layer insulation in the form of an insulating film. 2) The winding ends are led out by means of reversals (folds) of the winding strip in the direction of the coil outlet line or of the next winding. The distance between the individual sandwich windings in this case depends on the magnitude of the voltage and on the cooling conditions. Series connection can be simplified by altering the winding direction between adjacent coils. Connection then takes place by means of a simple cross-connection.   <IMAGE>
Patent DE-3144882-A1 (DE)
Title: Mechanism, in particular for a small electric motor
Inventor: HUBER WALTER
IPC: B60S1/16
Filed: 1981-11-12
Abstract: A mechanism with a drive shaft which carries a worm with a particular root diameter and the diameter of which is larger over wide areas than the root diameter of the worm, and with a worm wheel which meshes with the worm, is to be further developed in such a way that it permits low-cost and rapid manufacture. This is achieved by virtue of the fact that the worm is shorter than the length which the tip circle of the worm wheel cuts out of the drive shaft and that, on at least one side of the worm, the drive shaft has a notch which has a reduced diameter and into which the worm wheel plunges. The shorter worm makes possible a reduction in the milling time per drive shaft. Since the notches can be produced in the course of the turning down of the drive shaft, which is necessary in any case, the reduction in milling time is reflected in lower-cost manufacture.

Title: Profile strip for the sealing surrounding of windows on motor vehicles or the like
Inventor: HERMANN DIETMAR CHEM ING
IPC: B60J10/34
Filed: 1981-12-03
Abstract: Rubber surround strips of motor vehicle windows are advantageously produced from EPDM rubber by an extrusion process on account of the high flexibility, aging resistance and weathering resistance required for this application. Since these ethylene-propylene mixtures adhere only poorly to glass, however, according to the invention the strips are formed with a simultaneously extruded thin surface layer of an extremely adhesive rubber mixture in the area of the glass groove.

Title: Mobile concrete bucket
Inventor: WECKENMANN HERMANN
IPC: E04G21/04
Filed: 1981-12-09
Abstract: The invention relates to a mobile concrete bucket (21) having a base-side discharging device possessing a plurality of mutually parallel conveyor worms (22) for discharging the concrete from the bucket. The conveyor worms (22) are arranged in a frame (15) separated from one another by intermediate webs, said frame being mounted so as to be pivotable from a starting position which closes the bucket base (21) to a selectable inclined position. By virtue of a flexible sealing of the rubber band (17) and by virtue of lateral sliding plates (29) arranged on the frame (15) and also by virtue of an edge shaping of the bucket-base opening, a sealing of the concrete bucket space in the base region is guaranteed. By virtue of the selectable inclination of the conveyor worms (22), the discharging device can be adapted to the varying consistency of the concrete to be worked and to precast concrete parts to be formed. <IMAGE>
Patent DE-3151869-A1 (DE)
Title: High-temperature blower, in particular for annealing furnaces
Inventor: HILMAR VITS
IPC: F04D29/58
Filed: 1981-12-30
Abstract: The invention relates to a high-temperature blower for use, in particular, for annealing furnaces. Due to the offset design of the connection flange of the impeller, it is possible to extend the hollow shaft and hence the distance for heat transfer without increasing the overall length of the blower as far as the front side of the impeller. By virtue of the fact that the plane of gravity of the impeller is in the vicinity of the plane of fixing, a favourable load distribution is furthermore obtained, with the result that the impeller can be provided with point support on the hollow shaft and fixing at one flange is sufficient. The transfer cross-section of heat transfer from the impeller to the hollow shaft is correspondingly small. Finally, the hollow shaft can be surrounded with a jacket which provides protection against heat, the jacket for its part being covered by a sleeve as a shield. Thus, overall, only a small amount of heat is transferred from the impeller to the hollow shaft. The thermal loading of the bearing of the hollow shaft is correspondingly low.

IPC: H01L21/8226
Filed: 1982-02-16
Abstract: The invention relates to a process for producing an integrated circuit comprising an I<2>L circuit section and high-blocking transistors. According to the invention, only one uniformly thick epitaxial layer is deposited on a substrate and it is partially removed again in those regions in which the I<2>L circuit sections are situated. On the other hand, in the surface regions provided for the high-blocking transistors, the epitaxial layer retains its original thickness. In this way, the electrical characteristics of the high-blocking transistors and of the I<2>L circuit sections can be optimised with only one epitaxial layer.

Title: Device for production of granulate from 2-phase mixtures
Inventor: SCHERMUTZKI KONRAD ING GRAD
IPC: B01J2/26
Filed: 1982-03-17
Abstract: With the invention, an apparatus is described for producing drop granulate from 2-phase mixtures; in the process of the invention, the precrystallised melt from the precrystalliser is first fed to a rotor drop shaper and thence in drop form to the cooling path. Great advantages are obtained in product quality and controllability of the production process, which is in general critical, by the separation of the precrystallisation process from the shaping process. In an apparatus according to the invention for carrying out the process, the rotor drop shaper is connected to the precrystalliser by a feed pipe in which the raw material, in a preferred embodiment, is fed by a positive feed; this also gives important advantages. In a further advantageous embodiment, temperature regulation of the production process is controlled in dependence on the drop height of the end product.

Title: Method of improving the temperature independence of a silicon semiconductor device
Inventor: BERG HERMANN DR RER NAT
IPC: H01L29/10
Filed: 1982-06-01
Abstract: Silicon semiconductor devices, such as thyristors and triacs, are operated at temperatures between about -40 DEG C and +125 DEG C. In order to prevent spurious triggerings due to interfering currents, it is known to provide emitter short circuits which act as ohmic shunt paths; their design as lateral resistors in the gate base zone has the effect that their resistance becomes much higher at elevated temperatures, with the result that the susceptibility to spurious triggering also increases at elevated temperatures. For this reason, the capacity of the emitter short circuits has to be severely overdimensioned, as a result of which the triggering behaviour and the propagation of triggering are in turn adversely affected at low temperatures. The invention provides a zone structure for which the resistivity remains approximately constant or is reduced with increasing temperature since the electrical conductivity of the zone(s) which shunt the gate function and/or interfering currents is determined by impurities having an ionisation energy  DELTA ET in silicon of  DELTA ET > 0.065 eV.

Title: Curvic coupling with electromagnetic actuation
Inventor: BANGERT GUSTAV ING GRAD
IPC: F16D27/00
Filed: 1982-07-02
Abstract: A description is given of a curvic coupling with electromagnetic actuation, comprising two coupling parts, of which one is assigned the magnet part and the other is assigned the armature disc, both the armature disc and the coupling part provided with the magnet part having a curvic toothing which can be brought out of engagement by the electromagnetic actuation. One of the two curvic toothings is part of an independent ring which is mounted on an axial guide of the associated carrier and secured there. The advantage of this embodiment consists in the fact that the air gap between the armature disc and the magnet flange can be reduced to zero during assembly by an appropriate axial displacement of the ring. The attractive force of the magnet arrangement, which can furthermore be of four-pole design, can thus be doubled for the same size of magnet, making it possible to choose a magnet with a smaller overall size.

Title: Process for manufacturing containers from thermoplastics film and device for carrying out the process
Inventor: KIEFER GUENTHER
IPC: B29C51/26
Filed: 1982-07-17
Abstract: The invention relates to a process for manufacturing containers from a section of heated thermoplastic film by differential pressure by means of circulating intermittently pivoted moulds and to a device for carrying out the process. The containers are moulded in a moulding station and punched, then transferred to a rim cooling station and after a further pivoting movement pass into the stacking station. The containers are then transferred to stacking troughs. During the pivoting, the containers are held on the mould wall by vacuum suction. In order to be able to pivot the moulds out of the mould station more quickly than was hitherto known and therefore to increase the number of cycles without a deformation of the still hot and therefore plastic container rim occurring, it is proposed that the vacuum for sucking the containers also acts directly at the container rim and that a cooling and post-shaping of the container rim take place in a rim cooling station. The drive of the rim cooling station is integrated in a simple manner into the overall drive of the device. <IMAGE>
