Patent DE-4021671-A1 (DE)
Title: Device for rolling e.g. tyre tread strips - consists of thin rings locked in position by end clamping plates, round thin shaft to form eccentric profiles
Inventor: WALL KLAUS VON DER
IPC: B29D30/28
Filed: 1990-07-07
Abstract: Equipment forms materials into desired contours and, in particular, has a means of rolling rubber articles. The layout has a number of (pref.) identical rings (1) which can be locked together round the centre shaft (2) by means of two outer clamping plates (3). The rings (1) are pref. metal, with o.d. 200-300 mm and thickness a few mm only. It is essential that the i.d. of the rings (1) is considerably greater than the o.d. of the shaft (2). To form the required profile the rings can thus be held eccentrically about the shaft to a degree of up to 50 mm. The end clamping plates (3) can be fixed to the shaft by threads (4) but other means of locking them can be used. ADVANTAGE - The layout guides the contoured articles in a simple manner. It is partic. intended for use with raw tyre tread strips and similar in tyre winding.
Patent DE-4027127-A1 (DE)
Title: Studying oxygen@-ionising processes -  in which oxygen@ partial pressure is measured in lay of aq. medium less than 1 mm thick between oxygen@ sensor and oxygen@-consuming object
Inventor: LEISNER HARALD DR RER NAT
IPC: G01N33/18
Filed: 1990-08-28
Abstract: In studying oxygen-consuming processes, the redn. in oxygen partial pressure produced by an oxygen-consuming object in an aq. medium is measured against time. The partial pressure measurement is made in a layer less than 1 mm thick between the oxygen-consuming object and the oxygen sensor. USE/ADVANTAGE - Used in the continuous measurement of the absolute oxygen partial pressure in an aqueous medium in which oxygen-binding processes or oxygen-requiring enzymatic or chemical reactions are in progress, or which contain oxygen-consuming cells, tissues or parts of organs or organisms. The vol. of the aq. medium used is dramatically reduced, and therefore larger variations in the partial pressure with time are produced and the measurements are more accurate and require less time and are less susceptible to interference or interruption.

Title: Spinner stoppage correction - involves feeding core yarn into false twister to prevent risk of yarn length comprising only staple fibres
Inventor: BUISSON MICHEL
IPC: D01H15/00
Filed: 1990-12-01
Abstract: To correct a fault at a spinning assembly, where there is a drawing unit and a following pneumatic false twister with a core yarn feed to the delivery rollers of the drawing unit, the core yarn is initially passed into the pneumatic false twister on a stoppage at the drawing unit and the core yarn feed. When it is caught and held by the false twister, the drawing unit operation is resumed together with the feed of drawn sliver to the false twister. The core yarn is pref. laid in the pair of delivery rollers of the drawing unit, before the drawing function is resumed. On a stoppage, the drawing unit is opened, and the core yarn is laid round the pressure roller of the delivery roller pair to correct the stoppage. ADVANTAGE - The method avoids the risk that a section of the spun yarn is composed only of staple fibres without a core yarn in the centre.

Title: Automatically controlled cooling system - is for wide speed range IC engine and has valve behind engine block to regulate coolant circulation
Inventor: INGELHEIM PETER
IPC: F01P7/16
Filed: 1991-05-29
Abstract: The pump (1), is pref. a radial rotary pump. It circulates a liq. coolant through an IC engine. A thermostatically regulated flow control valve (10) is located behind the engine block (9) and alters the sectional area of the coolant pipe leaving the engine. A pressure limiting valve (22) or directional valve (30) opens a bypass (21, 31) to divert part of the pump output away from the components to be cooled. These are thus subject only to partial flow and the flow speed changes. USE/ADVANTAGE - More efficient cooling control of relevant components of IC engine avoids overcooling at high rpm.

Inventor: BARTELS ROBERT-JAN DR ING
IPC: F16N27/00
Filed: 1991-07-30
Abstract: The invention relates to a lubricating device for the tool shank end of a fluid-driven impact hammer, by means of which lubricating grease can be applied to the guide supporting the tool shank end at one location or at several successive locations via lubricating passages leading into the guide and connected to a lubricating-grease feed.

Abstract: A process is disclosed for removing hydrocarbons, cooling lubricants and/or oils from the surface of fine, in particularly anorganic chemical particles. The particles are submerged in an aqueous or water-containing cleaning solution, dispersed by high-speed agitation according to the stator-rotor principle and by simultaneous exposure to an outer or inner ultrasonic field.
