Patent DE-4027720-A1 (DE)
Inventor: HERTEL REINHARD
IPC: A47B9/20
Filed: 1990-08-31
Abstract: The invention concerns a leg assembly, preferably for a table, with telescopically extending legs. The invention also concerns a process for fabricating part of a leg. The aim of the invention is to improve this kind of leg assembly, in particular with regard to ease of fabrication and assembly and reliability in use. The invention achieves this aim by calling for a telescopic inside element in the leg to be designed, in the zone which passes through the shim of a locking device, so that it is sufficiently open on one side for the shim to be extensively exposed on this side and hence able to operate directly in conjunction with the locking device. Two or four legs with a common locking device preferably form a functional unit.

Title: Converting sinusoidal sensor signals of position measurement system - using offset scale division sensing with synchronised switches in alternate groups
Inventor: SCHLEICHER SIEGFRIED DR ING
IPC: G01D5/244
Filed: 1990-09-29
Abstract: The method converting sinusoidal position sensor signals into a phase modulated position signal involves acquiring several sensor signals using offset scale division sensing.  The signals are processed into discrete partial signals which are tapped according to a carrier frequency and summed to form a product signal. In each of a number of modulation paths the partial signals are grouped and processed according to mean value using tapping switches operated synchronously across the  paths. One partial signal group is switched through for an increasing signal and the other for a decreasing signal.  Onee switched group is inverted and added to the other. ADVANTAGE - Shape of converted signal remains undistorted despite reduced tapping switch switching frequency.
Patent DE-4031884-A1 (DE)
Title: Rapid continuous or batch datik dyeing -  in hot aq. dyebath at constant temp. with light agitation, without heat-up or levelling using simple appts.
Inventor: DORNIG DIETER DR
IPC: D06P5/12
Filed: 1990-10-08
Abstract: Process uses the diffusion properties of an aq. dyebath with sort-time technology, omitting the heat-up and levelling phase and conditions promoting levelness. The dyebath has a constant temp. between 40 and 120 (pref. 95) deg. C, is agitated lightly, is kept at pH 2-4, contains Glauber's salt of NaCl, contains no levelling agent and dispersant and/or contains dyestuffs having different, very pronounced migration in the dyebath. The goods are given a 5-60, (pref. 10-30)s dwell in the dyebath. USE/ADVANTAGE - The process is for producing a single or multicoloured patterned (batik) effect on commerically available substrates with conventional dyestuffs and is suitable for dyeing flexible materials, esp. textiles. The use of relatively high temps. gives fast dyeing in a short time. The process eliminates the need for costly appts. with high pumping power and temp.-time control, since only slight agitation of the dyebath, to prevent sedimentation, is desired.

Title: Combustion engine operation with individual cylinder fuel injection - introducing temporary inhibition of supply to cylinder showing excessive antiknock ignition retardation or preignition ionisation
Inventor: EMONTS JOHANNES
IPC: F02D41/36
Filed: 1990-11-29

Title: Mfg. and polisher through joining textile yarns - involves placing yarn layer on holding tape and sewing layer from outside against tape
Inventor: WEICHSEL LOTHAR
IPC: A47L13/16
Filed: 1991-04-30
Abstract: In the mfr. of a hand polisher, textile yarns are joined to each other. A yarn layer is placed in a laid-out holding tape across the tape course and sewn from the outside against the holding tape lying underneath it. The holding tape is turned over and folded so that the tape sections come to lie on top of each other. The overlying ends of the tape are sewn together and a stepped rolling up of the tape follows, starting at the joined ends. Every time the sewing thread joining the end reaches the vicinity of the still-flat top side of the layer, this thread is again pushed through the holding tape and tautened until the rolling process is completed and the thread is fastened. ADVANTAGE - The polisher is easily gripped by a hand and has a flexible core on one hand while the textile yarns are joined centrally and undetachably on the other.

Patent DE-4120318-A1 (DE)
Title: Low gas burner head - has central core extending into burner cover and gas connection throttling gas feed
Inventor: HEINZEL BENNO
IPC: F23D14/06
Filed: 1991-06-20
Abstract: The pointed central core extending into the burner cover reduces the throughput of gas by approximately twelve times, producing an amplified gas pressure between the burner cover and itself. The gas, which flows by the ring-shaped narrow point with increased speed and flows into the burner head, simultaneously brings with it the necessary quantity of fresh air and supplies the increased number of holes in the burner (2). As the inflow chamber in the burner head is very narrow, a blowing pressure appertains to the majority of the nozzles which are thus adequately provided with gas (5). USE/ADVANTAGE - A gas burner head to which a low amt. of gas is fed but at high pressure.

Title: Speed control system for hump shunting - uses times required by rakes of trucks to reach relevant sidings
Inventor: SOREMBA VOLKER DIPL ING
IPC: B61J3/02
Filed: 1991-11-29
Abstract: The system determines the maximum permissible speed with which rakes of rail trucks are pushed over a shunting hump. The times required for release and delivery into the sidings are either computed, or previously recorded in a calibrating operation, after which they are extracted from storage units as required. From the separation points between the rakes a minimum distance from the foremost detachment point is determined. From the times required for release and delivery to the relevant sidings the minimum times for these operations are also determined. The speed is computed from the quotients of the distance between its separation point and that of the preceding rake and of the minimum travel time difference between its delivery time and the release time of the preceding rake. USE/ADVANTAGE - Speed control during hump shunting of railway wagons determines speed without need for subsequent re-checking.
Patent DE-4143094-A1 (DE)
Title: Electronic fuel injection for IC engine - uses flywheel sensor to ascertain crankshaft speed and angle, camshaft providing fuel pressure to operate injectors
Inventor: DYBERG JONAS
IPC: F02D41/34
Filed: 1991-12-27
Abstract: The fuel injectors are supplied with fuel by pump (18) driven by the pulley belt (12). The fuel pressure is not enough to operate the valve at the injector nozzle. The extra pressure required to operate the injector is derived from the cams on the camshaft (32) and the sequencing of the injectors comes from an electronic control box (10), whose outputs operate electromagnetic valves. The input to the control box is a signal supplied by an inductive sensor mounted by the flywheel. The sensor sends a stream of pulses to the control box which indicate rotational speed and crankshaft angle and for a 6-cylinder engine, there are three angles at which one or other of a pair of injectors can be operated. The mark-space ratio of the sensor output is different for these three angular positions, so that the absolute crankshaft position is known by the control box at any time. USE/ADVANTAGE - Electronic fuel injection for vehicles. Uses flywheel to give necessary crankshaft speed and position; obviates the need for camshaft sensor.

USE/ADVANTAGE - For treatment of sludges contg. oils and other lipophiles. The efficiency of the procedure is improved, so that the oils etc. are separated to the maximum possible extent but are not released to the atmosphere.
