Patent GB-2074336-A (GB)
Title: Colourimeter Using 16 mm Colour Film Strip as Standard
IPC: G01J3/52
Filed: 1979-08-17
Abstract: The basic principle of any colour comparator (colourimeter) is to determine quantitative amounts by optical or visual comparison with a known sample or standard. This standard may be in form of a solution, glass filter or wedge, and when suitably illuminated the unknown sample can be compared or matched. If the quantitative value of standard is known a value of the unknown sample can be found. In this comparator a 16 mm colour film strip is used as a standard containing up to 10 colour densities which are equivalent to the specified amounts of dissolved or ionised substances in a volume. These colour densities on the film act as comparison filters and are therefore most suitable in comparators or similar instruments where an optical or visual comparison is preferred. <IMAGE>

Title: Video disc player having record handling mechanism
IPC: G11B17/032
Filed: 1980-03-12
Abstract: A record jacket or caddy (24), suitable for use with a video disc player, includes a sleeve and a record-retaining spine (28) removably located therein. Disposed on the spine are latch member (50, 52) for releasably locking the spine to the sleeve via recesses (66, 68). Latch defeat fingers (104, 106), disposed in the player, are wedged between the respective spine latch members and interior portions of the sleeve when a caddy is inserted to its furthest position in the player, so that the spine latch members (50, 52) are deflected inwardly in a manner freeing the spine from the sleeve. The player is further equipped with spine gripper members (116, 118) which engage projections (71, 73) for locking the spine (28) to the player, whereby subsequent sleeve withdrawal removes the spine and the accompanying record from the sleeve for retention in the player. The fingers (104, 106) are then deflected outwardly by springs (124, 126). To retrieve the retained record, an empty sleeve is inserted into the player, which causes a further outward deflection of the latch defeat fingers, which deflection in turn, results in inward displacement of the spine gripper members to release the spine from the player, whereby the spine and the associated record are removed from the player during subsequent caddy withdrawal. <IMAGE>

Title: Apparatus and method for sampling a liquid
IPC: G01N1/14
Filed: 1981-05-06
Abstract: An apparatus for sampling liquids flowing in open channels includes a cylinder 20, into which liquid is drawn by the action of a large piston 21. When the piston is drawn to the top of the cylinder, liquid enters at the bottom of the cylinder by way of an inlet 3 leading to a sample tube 2, the lower end of which is immersed in the channel. A small retaining tank 8 is located at the base of the cylinder so that, when the piston is reversed and the liquid expelled from the cylinder, a small portion is retained in this tank. The tank leads to a sample valve 11 which releases the contents of the tank into a collecting vessel 14 at the end of each sampling cycle. The apparatus includes a vent valve 24 to introduce pressurised air into the cylinder to purge liquid from the sampler. This apparatus is well suited for the application of pneumatic components to provide the control and the working power. <IMAGE>

Patent GB-2094636-A (GB)
Title: A cryosurgical probe
IPC: F25B9/02
Filed: 1982-03-04
Abstract: A cryosurgical probe having a tip portion E designed to control iceball formation and thus the freezing efficiency of the probe. The probe operates by the Joule-Thompson effect of gas cooling when expanded through a restriction J. In known probes, after cooling in this way, the gas is immediately vented to exhaust so reducing the dwell time of the gas in the tip. The probe disclosed is designed such that the cooled gas after passing through the restriction travels along a terminating passage 61 in heat exchange relationship with the wall of the tip before being vented to exhaust. The length of the terminating passage formed in the tip increases the dwell time there thus enabling better control of iceball formation. Moreover the length of the terminating passage is made adjustable, so that the iceball shape formed at the tip, between the restriction and the extremity of the tip, can be varied. <IMAGE>
Patent GB-2097283-A (GB)
Title: Filter arrangements for the exhausts of IC engines
IPC: F01N13/04
Filed: 1982-04-02
Abstract: A filter arrangement for the exhaust gas of an i.c. engine, for example a Diesel engine, comprises a pair of filter units (16, 17) through one of which the exhaust gas flow passes and through the other of which the engine inlet air flow passes at a given time, and ganged valves (18, 19) which periodically switch the exhaust gas flow from one filter unit to the other, and simultaneously switch the inlet air flow from the said other to the said one filter unit to flow through the latter in the opposite direction to the preceding exhaust gas flow so as to back-flush that filter unit, dislodging deposited solid particulate matter and transporting the dislodged matter into the engine air intake. The operation of valve means may be effected automatically in response to the increase in gas pressure difference across the filter element being traversed by the exhaust gas flow. In another arrangement, instead of two filter units a single rotary filter unit (101 or 120) of drum or disc type is provided, each sectional portion of whose element is traversed first by the exhaust gas flow in one direction and thereafter by the inlet air flow in the opposite direction to dislodge previously-deposited matter. <IMAGE>
Patent GB-2128821-A (GB)
Title: A multi-phase pulse position control
Inventor: DEASE IAN JOHN
IPC: H02P27/02
Filed: 1982-08-20
Abstract: A control for a three phase supply, e.g. for a motor driving a yarn take arrangement, uses a d.c. signal representing yarn tension to control the supply by varying the position in the cycle in each phase at which a triac fires to switch on the supply. The first firing pulse in one phase, generated by comparing the d.c. signal with a ramp signal, is used as a reference; and a slow count-up counter 2 accumulates 1/6 MHz pulses, derived from a 1 MHz clock oscillator 14b, during a power cycle. A fast countdown counter 5-7 repeatedly counts, at 1 MHz, the accumulated pulses, to determine the positions of the other five firing pulses required for a three phase supply. This system provides balanced firing without the need for setting-up procedures and without long term drift. <IMAGE>
