Title: Radial piston motor or pump
Inventor: HALLUNDBAEK JORGEN
IPC: F04B1/04
Filed: 1991-12-09
Abstract: ABSTRACT A motor or pump assembly comprises a cylinder block with a plurality of radially positioned cylinders, a piston arranged slidably reciprocable in each of the cylinders, a cam ring cooperating with the pistons and being rotatably journalled on the cylinder block, and a distributor valve arranged centrally in the cylinder block to control a flow of fluid to and from the cylinders in operation.   To obtain a relatively large diameter on the rollers and thereby less wear on both the cam ring and the rollers while reducing the outside diameter of the assembly, the rollers are journalled without axial lateral guide at the top end of the pistons, the pistons being guided by the sides in a groove provided in the cam ring.   The material of the pistons is moreover removed from both sides as far as the roller so that the piston with a central portion can follow the roller into the groove, whose depth thereby partly overlaps the travel of the piston.

Title: Process for the continuous production of high modulus articles from high molecular weight plastics
Inventor: WOODHAMS RAYMOND T
IPC: B29C48/95
Filed: 1991-10-08
Abstract: A process for producing a high modulus article includes forcing a high molecular weight plastic material, such as plyethylene, through a passage (30) of which the cross-sectional area diminishes in the forward direction of plastic flow, thus producing an extrudate (42). The plastic material is extruded while it is close to or at its melt temperature, and it is lubricated to obtain substancially plug flow through the passage. The speed at which the plastic material flows through the passage is adjusted so that the elongational velocity gradient at any longitudinal position within the passage does not exceed about 2.6 sec.-1, thus minimizing the degree of molecular orientation in the extrudate. The extrudate can be deformed by drawing while it is maintained at or close to its melt temperature, thus producing an oriented, deformed extrudate. The same is then quickly cooled to preserve the orientation. A suitable plastic material is high molecular weight polyethylene with an average molecular weight lying between about 500,000 and about 1,500,000.

Title: Location system
Inventor: BERNARD HERMANUS A
IPC: E21D9/00
Filed: 1993-08-06
Abstract: ABSTRACT            A location system for tracking miners underground includes a number of identification stations connected to a central control station. Miners are issued with portable identification modules which are fitted to their caplamps and which are powered by their battery packs. The identification modules transmit unique identification signals at intervals, which are picked up by the identification stations. The identification modules change the intervals between successive transmissions continually, and the identification stations can read overlapping transmissions, so that the reliability of detection is good. Miners who are issued with a caplamp first pass an identification card through a reader, which reads a unique personal identification code from the card. This code is correlated with the identification code of the identification module in the caplamp at the central control station. The invention includes a portable location device for tracking lost miners, which is a direction finding receiver adapted to receive and display the identification code transmitted by the identification module of a lost miner. The identification codes of members of a search party are stored in the device, so that they are ignored in use.
