Title: Textile reinforced rubber hose - continuous production in all sizes - with mandrel insertion prior to wrapping
IPC: B29D23/00
Filed: 1970-06-24
Abstract: Textile reinforced rubber hose, is made in any size and in lengths of 15 to 25 m by continuous process. A rubber core tube is first extruded and the interior immediately sprayed with a wetting and lubricating liquid. After quenching with water and drying with blown air, a mandrel is inserted and the reinforcement applied. The mandrel is withdrawn and an outer rubber tube extruded on an coated with a non- tick layer. The hoses are loaded into a water tank and the ends plugged when the hoses have filled. The load in the tank is cured in an autoclave. For insertion of the mandrel, the hose is laid straight pref. in a V-groove ona table. The wetting and lubricating liquid may be a solution of potassium soap or ordinary detergent and is injected at the extrusion head. This facilitates entry of the mandrel.

Patent DE-2155458-A1 (DE)
Title: Spacing tiles along conveyor - using intermediate conveyor producing excessive spacing
Inventor: KAMPHUES HERMANN
IPC: B65G47/31
Filed: 1971-11-08
Abstract: A method of assembling tiles or other stacked materials at predetermined intervals along a band operates by modifying the intervals between the tiles as they are supplied from a conveyor belt; the tiles or other objects are first transferred from the supplying conveyor belt in such a way that their spacing on this intermediate belt is greater than the final desired spacing; the subsequent transfer of each tile from this intermediate belt to the preparation band is effected with an associated advance step motion of the preparation band corresponding to the desired spacing between successive tiles. Pref. the speed of the preparation band is equal to or less than that of the intermediate belt; the supplying conveyor belt may be temporarily arrested after it has transferred a tile to the intermediate belt. The preferred appts. comprises the feed conveyor, intermediate conveyor and preparation band; the latter pref. runs at a slower speed or equal speed to the intermediate conveyor. Detectors at the start and end of the intermediate conveyor temporarily arrest the supplying conveyor to ensure the desirec wide spacing upon the intermediate conveyor and initiate the stepping motion on the final, preparation band which ensures the closest spacing of tiles along this band.

Patent DE-2410671-A1 (DE)
Title: Piston compressor for high pressure generation - has radially compressible piston rings located in cylinder wall
IPC: F16J15/46
Filed: 1974-03-06
Abstract: A cylinder of a compressor has piston rings located in the cylinder wall. The piston ring consists of three ring segments made from Teflon. The depth of the piston ring groove is such that a ring chamber is formed around the outside of the piston ring. The ring chamber pressure is a function of the cylinder pressure and is controlled by a pressure regulator. The pressure fluid that acts in the ring chamber flows through a heat exchanger so that the piston ring temperature can be kept at an acceptable level. Since the contact pressure of the seal ring on the piston is proportional to the cylinder pressure, the seal life as well as the compressor efficiency is increased.

Title: Flash welding control - compares welding pulse duration with set value to adjust clamping jaw movement for constant input
Inventor: KUTSCHUK-YATSENKO SERGEI IWANO
IPC: B23K11/24
Filed: 1975-02-06
Abstract: In a control system for flash welding the welding pulse duration is measured during the fusion operation for every period of the reciprocating movements of the clamping jaws with the workpieces. The measured duration is compared with a desired value. In case of a deviation, the velocity of movement or the amplitude of the movement of the workpieces relative to each other is altered accordingly. This keeps the energy input for each pulse constant so that the workpieces are heated more uniformly, the quality of the weld is raised and the welding time can be reduced. The allowance for the fused part can also be reduced.
