Patent GB-2040183-A (GB)
Title: Sample tube
IPC: G01N1/10
Filed: 1979-01-09
Abstract: A sample tube for obtaining a column of liquid of predetermined height in laboratory applications comprises a simple and effective construction, with a local restriction in internal diameter a predetermined distance from an inlet end and a movable valve member such as a lead shot disposed in the tube between the restriction and the opposite end, for co-operating with the restriction to retain a column of liquid at the level of the valve member and restriction by surface tension effects. In operation, liquid is drawn into the tube by suction to a level substantially above restriction, then the suction is removed and the liquid is allowed to drain out of the end, passing the lead shot owing to an imperfect seal between the lead shot and the restriction. When the liquid reaches the level of the lead shot and restriction, it is retained at this level by surface tension effects interacting with the lead shot and restriction.

Title: Valve Block Assembly
IPC: F16K27/02
Filed: 1979-06-01
Abstract: A valve block 1 with at least one built-in valve is described. The valve 6 is inserted in an opening 2 in the block having orifices to connecting bores 4, 5 and is sealed in the block by packings 14, 15.

Title: Mineral-mining cutter drum
IPC: E21C25/10
Filed: 1979-10-25
Abstract: A cutting drum for a mining machine comprises a drum body (6) and one or more helical vanes (10, 12, 14) extending around the drum body.

Title: Video Disc Stylus Position Sensor System
IPC: G11B19/14
Filed: 1980-12-17
Abstract: To provide control signals allowing compensation of stylus tracking in eccentric grooves of a video disc 10, a stylus 11 carries an electrode 13 disposed between first and second electrodes 14, 15 fixedly mounted on a motor driven carriage 8 to which stylus 11 is compliantly mounted. The capacitances of the variable capacitors thus formed vary with the displacement of electrode 13, and hence of stylus 11, relative to carriage 8. In Figure 1, complementary a.c. signals V1, V2 are applied to electrodes 14, 15 so that the algebraic sum of these signals capacitively coupled to electrode 13 is indicative of the position of the stylus. The output signal V3 from electrode 13, via processing circuit 29, controls a motor 31 to move carriage 8 so as to restore electrode 13, and thus the stylus 11, to a null position. In Figure 8 (not shown), an a.c. signal which has been amplitude modulated by voltage variable impedances is applied to the first and second electrodes whereby the time average of the signal summed at the stylus related electrode is indicative of the stylus position. <IMAGE>
