Title: Electromagnetically operable fuel injection valve for combustion engine - provides uniformly distributed flow through axial space whose width increases from periphery towards axis of valve
Inventor: HOLZGREFE VOLKER DIPL ING
IPC: F02M61/18
Filed: 1991-12-19
Abstract: The injection space (58) is bounded by a downstream end face (48) of a valve closure element (27) and a plate (46) perforated with spraying nozzles (49).

Title: Electric machine with rectangular teeth in magnetic circuit - reduces reluctance in path of magnetic flux between stator and rotor by interdigitation of pole pieces
Inventor: BACKHAUSS ROLF
IPC: H02K1/06
Filed: 1992-04-29

Patent DE-4214237-A1 (DE)
Title: Bobbin winder to take a running yarn - has opposing recirculating guide belts with yarn transfer from one direction to the other at each stroke end
Inventor: DEDEKEN RALF DR ING
IPC: B65H54/28
Filed: 1992-05-05
Abstract: The bobbin winder has a reciprocating yarn guide system where two parallel paths for the guides has a system to transfer the yarn at the end of the stroke from the yarn guide on one path to the guide on the other path which travels in the opposite direction. Reciprocating yarn guides are fitted to each path, tightly packed together, moved by a recirculating drive. Pref., the recirculating drive is a belt, where the yarn guides are fixed to the outer surface so that each belt level is part of a continuous belt and both are powered by a common drive, or they have separate drives. The yarn guides ride on a fixed sliding rail, with a keyed bond between the guides and the recirculating drive belts, with a separate sliding rail for each belt. The recirculating drive acts at just one point on the sliding rail and the recirculation of the guides is through the keyed link between neighbouring guides. The yarn guides can be formed by projecting combs from chain links, so that the links form an uninterrupted line of yarn guides on the outer side as a constant row of yarn guides. ADVANTAGE - The mechanism ensures that the yarn tension is constant, and that the yarn is safely caught on each direction change, even when working with high reciprocating speeds, so that the yarn is carried correctly along the bobbin length for even winding.

Abstract: The device with mirrors for reflecting an optical beam for treatment of surfaces (in particular, for hardening metals) is characterised by a rotary polygonal disc (30) with each two of its adjacent corners (33) bracketing two flanks (34) directed inwards. The angle (w) between these flanks varies from 80 deg. to 100 deg.

The angle between the adjacent mirror facets (34,34) is approximately a ringht angle. The disc (30) is provided with twelve pairs of mirror facets. The ratio of the outside dia. of the disc to the diameter of the facet intersections varies from approximately 1.3 to 1.5. The ratio of the flank length to the outside diameter of the disc is about 1:2. The incident beam is line-focussed onto the disc (i.e. with its large dimension in the direction of the axis of rotation and its small direction in the direction of the circumference of the disc). USE/ADVANTAGE - For surface treatment, for image nad signal processing, and in measurement technology. It results in a higher focal spot velocity, and enables larger powers to be transmitted.

Title: Contraceptive applicator which tests for leaks - provides airtight reception chamber with cylindrical wall adjustable in length, closed at one end and with receptor ring at other
Inventor: PANHOLZER FRIEDRICH DR
IPC: A61F6/00
Filed: 1992-12-09
Abstract: The plastics receptor ring (1) has a retaining rim (2) at its outer circumference. This ring is airtightly joined to the chamber wall (3) of airtight flexible material forming a cylinder when expanded. The end of the latter opposite the receptor ring is airtightly sealed by a chamber lid (4).

Rigid support inserts, e.g. a coiled spring (6), reinforce the chamber hose. The spring connects to both the ring and lid to force them apart. The lid and its frame form a container for the chamber wall, ring and contraceptive. When the container is opened and the applicator expands under the force of the tensioned spring a low pressure is created in the reception chamber formed by the chamber wall and lid so that the contraceptive expands. ADVANTAGE - It is of a simple construction and provides for easy application.

Title: Secure transmission of digital data over disturbance channels - immediately retransmitting digital data on recognition of insufficient signal strength estimated by receiver
Inventor: DIPPOLD MICHAEL DR
IPC: H04L1/20
Filed: 1992-12-10
Abstract: The method involves using a transmitter, installed e.g. in a vehicle, having a baseband section incorporating a buffer (111) for incoming data from an encoder (110), controlled by a redundancy decision unit (122) operating on an estimate (121) of a signal received (120) over the channel. A signature sequence (bk) is generated (113) for multiplication (114) by the readout from the buffer before modulation (112) at intermediate frequency. In the receiver, accumulated signal energy is estimated and a decision control interrupts the signature sequence and triggers an integrate-and-dump unit using clock recovery. USE/ADVANTAGE - Direct Spread Spectrum transmission. No acknowledgement channel is necessary. Throughput increased by transmission of only instantaneously required redundancy, and buffer memories need not accommodate more than one data packet.

Abstract: The invention relates to a method and to a low-shaft furnace for the disposal of filter dusts, filter sludges and filter ashes. In order to be able to obtain the charge quantity of such filter materials in the slags of the low-shaft furnaces and to recover a maximum quantity of valuable materials from the slag, it is proposed that the material for disposal is charged onto or into the slag bath, that simultaneously additives are introduced into the slag via an immersion lance and that, during the charging of the additives, the parameters determining the electric resistance, namely the height of the slag bath and the depth of immersion of the electrodes, are adjusted in a special way. For this purpose, the electrodes (21-26) have a defined diameter (D), and at least one delivery pipe (31-33) of a disposal feeder device (30) is provided in the upper part of the furnace vessel (12) underneath the cover (13). Parallel to the electrodes (21-26), a lance (41,47-49) is fixed to a support arm (43), which lance is connected to a burdening ring (42) and communicates via a sliding seal (14) with the furnace cover (13).

Title: Handbrake or parking brake which is secured against theft
Inventor: PICKERT HANS
IPC: B60R25/00
Filed: 1993-05-07
Abstract: The handbrake or parking brake which is secured against theft may be installed in all vehicles, agricultural machines, construction machines or other products having parking brakes.
