Patent GB-2037498-A (GB)
Title: Electric Couplings
IPC: H01R13/523
Filed: 1979-10-16
Abstract: A separable coupling (1) is contained in a fluid-tight enclosure (2, 3) having in it, or in communication with it, a fluid reservoir 6 of variable volume. This allows the coupling, filled with insulating liquid, to withstand very large pressure changes such as occur in 'sub-sea' installations normally operating at sea-bed pressure but pumped out to near- atmospheric pressure whilst alterations or adjustments are made. In the preferred form of reservoir, a piston 8 is sealed to the entering cable 5 and the surrounding wall by resilient skirts 9, so obviating the need for a separate seal round the cable. In another embodiments (Fig. 5, not shown) the fluid reservoir (18) is outside the enclosure (2, 3). <IMAGE>
Patent GB-2034474-A (GB)
Title: Method of determining equivalent reflector sizes in an automatic ultrasonic testing system
IPC: G01N29/30
Filed: 1979-10-19
Abstract: A method of determining equivalent reflector, i.e. flaw, sizes in an automatic ultrasonic inspection system operating according to the pulse-echo technique with one or more test probes moved relative to a test-piece, corrects the depth-dependent amplitude of the echo from the test-piece rear wall for depth in such a way that, the amplitude of the echo from a reflector (9) lying perpendicular to the scanning beam and whose area is greater than or equal to the cross-sectional area of the scanning beam (8) at the depth of said reflector is independent of the depth of the reflector. From the measurement values of each test shot (8) a ratio value is obtained from the amplitude of the echo from a reflector and the depth- corrected amplitude of the echo from the rearwall; this ratio value is multiplied by the cross-sectional area of the scanning beam at the depth of the rear wall; and the product of the multiplication is utilised as a measure of the partial or whole surface area of an equivalent reflector. Both the scanning beam cross-section at the depth of the rear wall and also the partial surface area of the equivalent reflector are represented by rectangular areas instead of circular areas. <IMAGE>

Title: Track skipper apparatus for video player
IPC: G11B21/08
Filed: 1979-10-25
Abstract: In a video disc player, a carriage 16 is subject to translatory motion in correlation with radial motion of a play- back stylus 54 relative to a disc record. A stylus arm 50 carrying the stylus at one end thereof has the other end pivotally secured to the carriage. A permanent magnet 100 is mounted on the stylus arm 50 near its free end. A pair of spaced coils 102, 104 having non-magnetic cores are disposed on the carriage 16 such that the stylus arm-mounted magnet 100 is interposed therebetween. The coils are selectively energized to change the radial location of the stylus relative to the record. This enables repositioning the stylus forward or backward e.g. for special effects or for correcting incorrect track following. <IMAGE>

Title: Cup dispense assembly
IPC: G07F13/10
Filed: 1980-02-08
Abstract: A cup dispensing assembly for a vending machine which assembly comprises a cup receiving platform (21) for receiving a cup at a dispensing station in a vending machine, a cup transport means including a cup carriage (32) and associated cup support for transport of a cup to said cup receiving platform, reversing means for reversing the motion of the transport means when the cup is juxtaposed and supported by the cup receiving platform at the dispensing station, the arrangement being such that as the cup is conveyed forwardly towards the cup dispensing station convergence between the receiving platform and the cup support occurs so that the cup rides up a surface of the platform whereby continued forward movement of the cup carriage results in further convergence between the cup support and platform to produce relative movement between the cup and the cup support to an extent sufficient for disengagement of the cup from the cup support on reversal of transport means without substantial spillage of the contents thereof. <IMAGE>

Title: Ash processor
IPC: B02C17/02
Filed: 1980-02-25
Abstract: To minimise air-entrainment of light cremation-ash particles during filling of such ash into perforate drum 10 and, optionally, during pulverisation of the ash by the action of balls (not shown) when the drum 10 is rotated, air from a casing 14, around the drum 10, is aspirated through a filter 35. Urn box 26 is correspondingly aspirated by way of a duct 37. In the illustrated case, heavy particles can fall into urn 29, as also will particles from the underside of the filter 35 when the aspirator is switched off, but in a modification all of the ash, after pulverisation, is taken into the filter which is of upright cup-shaped form. <IMAGE>

Patent GB-2072145-A (GB)
Title: Liquid core sampler
IPC: G01N1/10
Filed: 1981-02-18
Abstract: This invention relates to an interface sampling device for determining the thickness of the water layer in a water-oil mixture. The device makes use of a trigger mechanism 7, 8, 9 to which the valves 35, 38 of a sample chamber 1 respond. That is, when the trigger is loaded and the device immersed in the mixture, the valves are open allowing free flow of the sample in and out of the chamber enabling the sample in the chamber to attain equilibrium with the surrounding oil/water mixture. Upon unloading the trigger 7, 8, 9, the valves 35, 38 snap shut rapidly, trapping the sample within the chamber. The device ensures that samples collected are representative and is particularly suitable for measuring thickness of a water layer in tanker bottoms. <IMAGE>
