Title: Socket-like electrical connection
Inventor: HASS JUERGEN
IPC: H01R13/18
Filed: 1988-05-05
Abstract: The connection comprises an integral body part (2) which has a U-shaped cross-section and consists of a metal which can be hammered, by means of which a crimped ferrule (26) is integrally formed. The body part (2) is accommodated in an integral, box-like spring part (32) which consists, for example, of stainless steel. A contact spring (60) extends from the rear end of an upper wall (34) of the spring part (32) to the front beyond the front end (10) of the body part (2) and has a curved contact region (65) in the vicinity of this front end (10). A flat-plug-like connection (T) which can be connected to the socket-like connection is inserted through an opening (42) in the spring part (32) in such a manner that it is gripped between the contact region (65) and a flat mating contact surface (18) of an indentation (16) which is formed in a base wall (4) of the body part (2). The connection is suitable for use when subject to severe temperature fluctuations. <IMAGE>

Title: Impact-tough and stiff polyamide alloys
Inventor: DALLA TORRE HANS DR PHIL
IPC: C08K5/1515
Filed: 1988-07-14
Abstract: The invention relates to moulding compositions of thermoplastically processible polyamide alloys having high impact toughness, stiffness and dimensional stability, which contain one or more elastomeric polymers and one or more epoxy compounds with more than one epoxide group. These moulding compositions are characterised in that the elastomeric polymer is an  alpha -olefin copolymer which has subsequently been grafted with not more than 1% by weight of one or more  alpha , beta -unsaturated dicarboxylic acids and then contains not more than 2 mol% of carboxyl groups. The moulding compositions of the invention show, compared with existing compositions, as well as high impact toughness, stiffness and dimensional stability a particularly low creep and shrinkage tendency, despite the fact that less modifier is required than in the case of comparable impact-toughened polyamides.

Patent DE-3830216-A1 (DE)
Title: Process and apparatus for the production of an optical waveguide preform
Inventor: BAUCH HARTMUT
IPC: C03B37/018
Filed: 1988-09-06
Abstract: In the production of coated glass tubes by the known PICVD process, the coating rate in the gas flow direction drops due to the pressure gradient along the coating zone. By diluting the mixture of reaction gases flowing into the coating zone with a dilution gas, the axial pressure drop in the flow direction of the gases is just compensated. This allows the coating rate to be kept constant over the entire coating zone and the economics of the process to be improved. Production of an optical waveguide preform. <IMAGE>
Patent DE-3835582-A1 (DE)
Title: Drilling device having a means for extracting the drilling dust
Inventor: FISCHER ARTUR PROF DR
IPC: B23Q11/00
Filed: 1988-10-19
Abstract: Drilling devices are known, which use an extracting bell to extract the drilling dust produced during the drilling operation. In the case of known drilling devices, however, the extraction is often possible only to a limited extent at the start of the drilling operation. There is proposed a drilling device having an extracting bell which is displaceable axially along the drill and can extract the drilling dust produced, as soon as the drill point touches the workpiece. The extracting bell consists essentially of a tubular section which is sealed off from the drilling shank on one side.

Patent DE-3907755-A1 (DE)
Title: Connecting part for profile rails for receiving suspended ceiling elements
Inventor: KAUFMANN JACOB UWE
IPC: E04B9/14
Filed: 1989-03-10
Abstract: A connecting part for profile rails for receiving suspended ceiling elements exhibits a junction part and arms, branching off horizontally from said junction part, for receiving in each case one end of the profile rail. In this arrangement, each arm is designed to be adapted to the profile of the profile rail such that the profile rail can be plugged vertically under the arm from beneath and can be rested by means of a lock bolt which can be pushed in horizontally. Consequently, it is made possible to mount or demount even a single profile rail in a suspended ceiling structure without other ceiling parts being influenced thereby. In order to align a plurality of profile rails relative to one another in a common connecting part, use is made of the side walls of a covering element which can be plugged into the junction part, provision further being made, on the underside of each arm, of a centring pin which ensures that, upon pushing in the lock bolt, the profile rail is pressed fixedly against the connecting part and is also drawn towards the side walls of said covering part and aligned therewith. The connecting part and the associated plug-on parts may exhibit a common through-passage channel, with the aid of which additional structural elements, e.g. lights or wall elements, can be fastened on the connecting part.

Inventor: SCHULZE WOLFGANG
IPC: G01R31/30
Filed: 1989-04-01
Abstract: Method and device for testing the time response of digital circuits.   The intention is to measure the delay time occurring between the application of stimulus data at the input and their appearance at the output of a sample, using simple means. Measurement is carried out in a plurality of test sequences which follow one another and contain a specific number of test steps, and the output data of the sample (1) are sampled using a programmed waiting time which increases incrementally with the test sequence. For the measurement, use is made of a computer (5) which contains the test program and determines the measurement run, with the aid of pin-electronics consisting of a waiting-time unit (4), an output unit (2) and an input unit (3). The method can be used for inspecting the dynamic response of digitial components. <IMAGE>

Title: Distributor for reactors and reaction columns - includes distribution floor having separate distribution systems for liq. and gaseous reagents
Inventor: KUBERSKY HANS-PETER DR
IPC: B01J8/02
Filed: 1989-11-28
Abstract: A floor design for the distribution of liq. and gas reagents in a vertical tube reactor or packed column incorporates separate distribution systems for the liq. and for the gaseous reagents. The liq. reagent distribution is by means of openings drilled in the floor plate, and the gas distribution is by means of overflows which project above the normal depth of the liq. on the floor and formed by further openings drilled in the floor and provided with collars. These collars may be in the form of pipe stubs. The floor openings are uniformly distributed over the surface of the floor. The edges of the openings for the liq. reagents are drawn downwards, and deflector plates are fitted below all of the openings. The overflows have a diameter and spatial arrangement which do not interfere with the flow of the liquid reagents. USE/ADVANTAGE - This invention presents a new method of simultaneous distribution of liq. and gaseous reagents over the upper surface of the reaction bed or packing material in a vertical tube fixed bed reactor or a vertical packed column reactor. Even distribution of the reagents over the surface of the fixed bed or packing material is achieved, and the performance of the reactor is therefore greatly improved.
