Title: Valve-type closure for containers
IPC: B67D1/08
Filed: 1981-04-21
Abstract: In order to reduce the risk of inadvertent removal from an internally-pressurised cask or keg of a valve-type closure through which the contents are discharged, the valve body (15, 16) has rotationally- mounted on it an axially-trapped sleeve (23) which is threaded into the usual fixed socket (11) on the cask or keg. As the sleeve is screwed in, a peg (24) on the body enters a channel (25) in the socket to guide the body axially into the socket. On attempted removal of the sleeve (23) without a special tool to restrain rotation of the body in the unscrewing direction, the body tends to rotate in the unscrewing direction and the peg (24) enters a blind-ended passage (27) so preventing removal of the closure. However, the body moves axially sufficiently to open a gas-relief passage (29) from the cask or keg to atmosphere. <IMAGE>

Title: Cargo refrigeration
IPC: B65D88/74
Filed: 1982-03-16
Abstract: A refrigerated cargo container having a refrigeration unit of variable capacity and an adjustable null band of temperatures over which the unit is inoperative is controlled by the lower temperature sensed by two temperature sensors positioned in the airflow to and from the cargo space. The physical construction of the container is described in some detail. The refrigeration unit has a compressor 1 feeding refrigerant via a line 18 to a condenser 2 and thence (via a receiver 4 and line 21) to an expansion valve 13 and evaporator 3. The temperature sensors 22, 23 in the air outlet from and inlet to the refrigerated space are connected such that the lower L of the two temperature signals therefrom is compared with a reference value S, the resultant error signal E being used to control a throttling valve 12. As the sensed temperature falls so that E drops below a first preset temperature T11, a bypass valve 11 is closed and the variable valve 12 is used to restrict refrigerant flow, but not below a minimum flow value. If E drops further, below a lower preset temperature T8, a valve 8 is opened to divert some compressed vapour directly to the evaporator, via line 20. A selector 41 sets a null temperature band in which the compressor does not run, while a comparator 64 and delay 45 prevent rapid switching ON and OFF of the compressor. Comparators 65, 66 energise heater 54, 55 in stages if the temperature continues to drop despite the compressor being off. <IMAGE>

Title: Fluid-responsive apparatus
IPC: G01F1/76
Filed: 1982-05-07
Abstract: Apparatus for measuring mass flow or density of fluid has a turbine (3) mounted resiliently by torque rods (42 and 43) within the fluid-flow line (1). The turbine (3) has radial vanes (32) to define passages (33) parallel to the flow of fluid. A torque driver (4) causes oscillatory rotation of the turbine so as to give fluid in the passages (33) a component of displacement at right angles to the passages. The turbine (3) is driven simultaneously at two frequencies, displacement being sensed by a pick- off (5). The first frequency f90 is adjusted so that a 90 DEG phase difference is produced between the drive signal and the turbine displacement-the density of fluid being derived from this frequency. The second frequency fD is a fixed fraction F of the first frequency, the phase difference between the second frequency and turbine displacement being used to derive an indication of mass flow. <IMAGE>

Title: Fault location arrangement for digital optical transmission system
Inventor: GIACOMETTI ALBERTO MARIA
IPC: H04B10/00
Filed: 1982-12-23
Abstract: A fault location arrangement for a digital optical transmission system employing repeaters (2) has at each repeater an opto-electrical converter (55) and an electro-optical converter (5). The output of the opto-electrical converter (55) is fed via an AGC amplifier (57) and a regenerator (63) to a modulator (200) which comprises a two pole two way switch (40), a single pole two way switch (41) and two current sources (51,52). The two pole switch (40) is controlled by the regenerated data while the single pole switch (41) is controlled by a fault location signal (F2). The arrangement is such that fault information is transmitted by amplitude modulation of the digital signal but that the average power applied to the electro-optical converter (5) remains constant. Hence the amplitude modulation does not cause a varying dissipation in the converter (5) and hence reduces the possibility of variation of the wavelength emitted by the converter (5).

Patent GB-850229-A (GB)
Abstract: 850,229. Valves. RADIATION Ltd. Aug. 26, 1957 [Sept. 10, 1956], No. 27576/56. Class 135. A gas valve is actuated by a lever moved by a heat-sensitive device slowly deformable by a heating means separate from a pilot burner but brought into operation by bringing the pilot burner into operation. On operating a pilot burner tap and igniting the pilot burner, the tap also actuates a switch whereby an electric heater r, clamped to a tapering triangular section bar n secured by flanges p to the housing a, is energized so that the bar is heated and bends and through the pin o, slowly opens the main gas valve e carried on a lever f pivoted on a leafspring g adjustably carried on bolt k. The valve e fully opens after from 5-10 seconds, the main burner being ignited by the pilot burner before it is fully open thus preventing any explosion. A thermostatic switch controls the heater and the valve e, the pilot burner remaining alight. In a modification the bar n is heated by burners supplied through a thermostatic valve and a gas tap and ignited by a pilot burner, the bar actuating the valve e via an adjustable screw, sealing diaphragm and lever. The valve is applied particularly to air and water heaters.
