Patent DE-4134891-A1 (DE)
Title: Fine atomisation fuel injection nozzle - has ring gap, adjusted relative to flow rate, small gap width and long length to promote fine fuel atomisation
Inventor: EISFELD FRITZ PROF DR ING
IPC: F02M61/06
Filed: 1991-10-23
Abstract: The fuel injection nozzle has an annular gap  between the nozzle body (1) and a central needle (3) with a cross-section, which is adjusted corresp. to flow rate. Limitation of the gap width to a few  mu , together with relatively long gap length, achieves very fine fuel atomisation, due to the large transverse force in the fluid. A deflector is located on the journal of the nozzle head. The injector needle has spiral recesses above the needle seat. Radial channels are located in the baffle surfaces. USE/ADVANTAGE - Fuel injection nozzle giving very fine atomisation.
Patent DE-4134980-A1 (DE)
Inventor: GOERNER EUGEN
IPC: B60S1/46
Filed: 1991-10-23
Abstract: The invention concerns a wiper for motor-vehicle windscreens. The wiper has an arm which is attached, by means of an injection-moulded fitting, to a shaft which is driven to carry out an oscillating motion. The wiper arm has a joint element which is essentially U-shaped in cross-section, whose side walls grip the attachment fitting and which is articulated to the attachment fitting. The wiper arm preferably has an attachment-fitting cover plate which is essentially U-shaped in cross-section and whose side walls grip the attachment fitting. The wiper also has a liquid-feed line which is led along the wiper arm to supply a nozzle with windscreen-washing liquid. The aim of the invention is to enable the liquid-feed line to be mounted easily on the wiper arm in the area of the attachment fitting. This is achieved by virtue of the fact that the side of the attachment fitting has a channel along which the liquid-feed line runs and which is covered by one side wall of the joint element or cover plate.

Title: Partial decarbonisation of water esp. drinking water - by trickling water through filter and simultaneously lowering pressure to backwash filter and flowing carbon di:oxide-free inert gas through filter
Inventor: KRATZENSTEIN KLAUS DIPL ING
IPC: C02F5/02
Filed: 1992-01-16
Abstract: Partially decarbonisation of water by pptn. of calcium carbonate in the presence of crystallisation nuclei in the form of calcium carbonate-contg. material in a filter bed of granulated solid material. Water is trickled through the filter bed with simultaneous lowering of the pressure to back wash the filter bed so that 10-20% of the calcium carbonate ppted. during decarbonisation remains in the filter bed. Inert gas practically free of CO2, pref. air is used to mechanically clean the filter during decarbonisation by flowing it through the filter bed pref. in countercurrent flow to water. The vol. ratio of water to inert gas used is 1:0.5 to 1:1.5 esp. pref. about 1:1. USE/ADVANTAGE - Esp. used for purifying drinking water. The method gives energy savings of about 25-30% and crystallisation and retention of the CaCO3 on the trigonal filter material of over 90% which reduces the amt. of rinsing water required.

Title: Vehicle course matching method - using navigation system which determines actual distance covered and deviation of actual route from predetermined route
IPC: G08G1/0968
Filed: 1992-03-24
Abstract: The actual travel route is computed by the navigation system comparing the actual travel route with the predetermined travel route, and matching a running vehicle position to a vehicle position along the predetermined route. Points are determined as course alternation points (A,B,C,D) at which the direction of the movement of a vehicle, alters at least at a predetermined angle. A start point (O) is determined as the actual start of a travel route or a suitable course alteration point of the vehicle. A point is determined as an actual end at which the vehicle, from the actual start point on the actual route, has passed through a determined number of route alterations. An actual vector is determined between the actual start and the actual end. A reference vector is computed between the actual start and the end in the predetermined travel route. The actual value is compared with the reference vector, and the actual end is identified as the reference end, if the actual vector and the reference vector coincide with each other.
