Title: Die-casting method and apparatus
IPC: B22D17/10
Filed: 1979-02-14
Abstract: A die-casting method and apparatus adapted to be used for production of, for example, housing members of compressors, pumps or the like, wherein a molten metal injected into a forging die cavity (30) may be applied with pressure through a location other than an injection port. This invention has for its object to improve the sliding property of a plunger (36) for applying the forging pressure. The pressure plunger (36) is slidably fitted in a pressure sleeve (35) which has an enlarged portion (35a), said pressure plunger (36) being also provided with a reduced portion (36d), so that the pressure plunger (36) may be smoothly moved with the solidified metal layer being kept in the minute gap formed between the pressure sleeve (35) and the pressure plunger (36). Thus, the flash of the solidified metal layer is prevented from clogging in a portion between the pressure sleeve (35) and the pressure plunger (36), so that the sliding movement of the pressure plunger (36) is kept normal. <IMAGE>

Patent GB-2091797-A (GB)
Title: Permutation lock
IPC: E05B37/02
Filed: 1980-12-03
Abstract: This discs 37 of a permutation lock are mounted on a cylindrical core 3 having a longitudinal slot 6 along part of its length. The discs each have an axial through slot (46) at its inner, circumference extending from one side to the other, and there is an elongate bar 7 having a spring strip 8 attached at its rear to bias it outwardly into the slots (46). The arrangement is such that, when the disc slots (46) are not aligned with said longitudinal slot 6, the bar 7 lies in said longitudinal slot 6 and is prevented from longitudinal movement by a stop 11 at one end of said longitudinal slot, so as to prevent release of the lock. When the disc slots are aligned within the slot 6, the bar rises to lie at least partly within the disc slots and so clears the stop 11 and is thereby free to move longitudinally to release the lock. <IMAGE>

Title: Transmitting fluid pressure from one fluid to another for use in a sub-sea well head
IPC: E21B33/035
Filed: 1981-02-19
Abstract: A fluids isolating pressure transmitter wherein a bellows unit (14) is guided for longitudinal expansion and contraction within a cylindrical bore (12). The bellows unit (14) is sealingly closed except for entry of a first fluid under pressure through a fluid connector (20) closing one end of the bore, while a fluid connector (24) closes the other end of the bore except for entry of a second fluid under pressure which is contained within the bore to oppose the pressure of the first fluid, which is fully isolated from the second fluid within the bellows unit. The transmitter is especially suited to use at a well head, in particular a sub-sea well head, for transmitting the crude oil pressure to an hydraulic operating fluid, being capable of production as a sealed welded unit avoiding reliance on elastomeric seals either for isolation of the two fluids or their separation from the external environment. <IMAGE>

Title: Determining linear measurement
IPC: G01B7/02
Filed: 1981-05-12
Abstract: A method of determining linear measurement is based on the procedure of passing a current pulse from a generator (42) along a conductor (20) within a tubular member (10) and timing the return of the resulting sound wave along the tube (10) arising from the intensification of the magnetic field of the pulse by a magnet (1, 2 or 3) adjacent the tube (10). The method consists of providing two magnets (1, 2) a fixed distance (D) apart adjacent the tube (10) and positioning one or more further magnets (3) adjacent the tube (10) whose distance (M) from one of the fixed magnets (1 or 2) is to be determined and which is arrived at by ascertaining the corresponding time intervals (T1, T2) from timing the sound wave returns due to the magnets (1, 2 and 3).

Title: Ground signal rejection metal detector with transmit-receive coil
Inventor: HIRSCHI RICHARD EDWARD
IPC: G01V3/10
Filed: 1981-09-03
Abstract: A circuit capable of detecting small metal objects, such as coins, buried in soil containing magnetic minerals, and of rejecting the ground signal produced by such soil, includes a free running oscillator operated Class A and connected to a single sensor coil 14 which both transmits and receives signals. Temperature compensation for preventing coil impedance changes with temperature variations, to provide a more stable oscillator, is achieved by arranging that an eddy current voltage is induced in the coil having a resistive component equal to the resistance voltage drop across the coil. The circuit includes a single control 18 for adjusting the oscillator transistor 10 for Class A oscillation with near unity gain, whereby the negative peaks of its emitter voltage 15 substantially equal the positive peaks of its collector voltage 17. Thus the D.C. level of the oscillator output voltage 15 changes with its amplitude to detect the presence of a buried metal object. This change in D.C. output level is sensed by an indicator means to produce a modulated audio signal which indicates when a metal object is detected. <IMAGE>

Patent GB-2089233-A (GB)
Title: Spray booth apparatus
IPC: B05B15/12
Filed: 1981-11-02
Abstract: An improved water-wash spray booth of the type in which exhaust air lifts liquid from a reservoir 23 via air liquid separators 28 to a trough 17 and such lifted liquid flows from the trough 17 over a floodsheet 15 back to the reservoir. An open top chamber 38 is positioned immediately below the liquid surface within the reservoir and is connected at its bottom to a conduit 40 which discharges into the reservoir at a location spaced from the chamber 38. A flow of liquid from the trough 17 above the floodsheet 15 via a pipe 42, 43 induces a turbulent flow of liquid from the surface of the reservoir downwardly through the chamber 38 and out the conduit 40 for breaking up paint particles into smaller particles, which collect as a mat at the bottom of reservoir 22. As shown, fan 35 draws air through the system to entrain liquid which is separated from the air firstly at 28, then at 30, then at 32. More than one nozzle 43 may be used, and pipe 40 may have a venturi construction. <IMAGE>

Title: Tamper indicating closure
Inventor: GACH PETER PAUL
IPC: B65D41/28
Filed: 1982-07-05
Abstract: A tamper indicating closure includes an outer cap (20) carrying an inner liner (30) which relies on relative movement of the outer cap and the inner liner during opening movement to indicate tampering (e.g. by "opened" on liner appearing in aperture 60 in the cap) with the container after it has been sealed for the first time, the relative movement being ensured by a friction surface (34) which coacts with the inner surface (35) of an opening in the container to resist rotation of the liner and maintain it in a sealed condition while the outer cap is being rotated in an opening direction. Once opened, the outer cap (20) and the inner liner (30) are maintained in a position for movement as a unit in both the opening and closing direction of the closure. On initial application to the container drive elements (50) in the cap engage surfaces (46) on the liner and "sealed" appears in aperture (60) and on first opening of the container the drive elements pass over ramps 66 into the spaces between surfaces (48) and (68) and "opened" appears in the aperture (60) and the drive elements are thereafter retained in those spaces. <IMAGE>
