Title: Rolling screw drive system - has nut acting as ring-gear with planetary grooved rollers engaging screw thread
Inventor: OETJEN JUERGEN
IPC: F16H25/22
Filed: 1991-05-15
Abstract: Inside its bore the nut (5) has parallel ring grooves arranged in two axially spaced sections.

Patent DE-4143158-A1 (DE)
Inventor: RIENHARDT HANS PETER
IPC: B60S1/16
Filed: 1991-12-28
Abstract: Windscreen wiper mechanisms, especially for motor vehicles, have a wiper spindle (8) carrying the wiper arm with the wiper blade at its free end. The wiping angle must be limited so that the blade travels through a predetermined wiping angle. This means that the wiper spindle (8) must reverse its direction after passing through the wiping angle. Precise limitation is obtained with the aid of a stop (10) which alternately meets stop surfaces secured to the drive housing. The stop (10) is preferably a radial projection of an annular component (11) which may be fixed or rotatably fitted on the wiper spindle (8). In the former case it is driven by the wiper spindle and in the second by a drive pinion. Shortly before reaching the reversal point it comes against either an elastic buffer or a stop surface (16, 17) of a trannsmission member (13) which in turn co-operates with a buffer (19) and thus causes damped braking at the reversal positions.
Patent DE-4203625-A1 (DE)
Title: Gripper for removing hot dishes or plates from oven - has jaws to grip rim of dish or plate and spring fitted to handles to hold jaws open
Inventor: RUTKOWSKI HANS

Title: Fibre bonding - uses pectin and compression to form sheet of flax jute or hemp
IPC: D06M15/705
Filed: 1992-12-16
Abstract: A process to stiffen or bring a web of natural fibres into a cohesive sheet. The fibrous material is handled in a manner that pectin in a solvent bridges the gaps, the solvent is removed with the intention of hardening and binding the fibres. Pref. the solvent used is water or steam, which may have a cleaning agent added. Following impregnation and drying, which may be in some form of oven, the sheet of material is compressed. A calender is employed for this, alternatively, pressed in a mangle before drying. As a result the textile product is given a definite form. This may then be applied in other directions, as a base in the same manner as a bonded fabric. The process is particularly suitable for a flax, hemp and jute. These fibres contain some pectin before retting. Other processes may be applied, either prior to subsequently, such as needling, laminating, foam covering, laminating or adding other resinous substances. ADVANTAGE - The pectin is a natural prod. which is environmentally friendly, and there are no difficult manufacturing procedures. There are several practical applications.

Title: Speaker verification system using nearest neighbour distance - accepts or rejects identification of speaker claiming to be registered speaker on basis of relationship between distance and given threshold
Inventor: HIGGINS ALAN LAWRENCE
IPC: G07C9/00
Filed: 1993-03-29
Abstract: The system includes a processor for processing spoken text into speech blocks. A register registers a speaker into the system.

Another device determines a verification value from the distance data and, from that, determines whether the speaker is the registered speaker he claims to be. A device in the distance determining device determines the euclidian distance of the nearest neighbour between speech blocks which belong to the spoken test word and blocks which belong to the registered words. ADVANTAGE - Has low error rate and minimises verification processing time and/or reduces necessary computing power.
