Filed: 1982-12-23
Abstract: Control means are provided for use in a pressure fluid line 11, 12, comprising a valve arrangeable in the pressure fluid line, the valve being such that if there is a reduction in pressure on the downstream side of the valve such as to indicate a burst or substantial leak, the valve acts to stop or restrict flow through the valve. When the valve is positioned in a high pressure line valve spindle 19 is raised so that a substantial quantity of fluid can flow past the sealing face 20. If however there is a sudden drop in pressure on the downstream side of the valve the spring 28 returns the valve spindle to the position shown and flow can only take place through the restriction element 30. <IMAGE>
Patent GB-2115487-A (GB)
Title: Double wall compressor casing
Inventor: BURGE JOSEPH CLAYTON
IPC: F02C7/24
Filed: 1983-01-06
Abstract: In a gas turbine engine, the casing 25 is provided with a nonstructural inner wall removably attached to a thin, structural outer casing. The inner wall isolates the thin stator outer casing during transient turbine operations of throttle burst (heavy throttle) and throttle chop (reduced throttle). During throttle burst and chop, the nonstructural inner wall delays rapid heating and cooling of the relatively thin-walled outer casing, and reduces radial clearance d between the stator casing and blade tips due to uneven thermal expansion and contraction. To fine tune the actual clearances d between stator and blade tips and prevent the casing outer wall from overheating, thermal insulation material 27, 29, 31 is used between the nonstructural inner wall and outer casing. <IMAGE>

Patent GB-2136071-A (GB)
Title: Rotary conduit joint
Inventor: ORAM JOHN ANDERSON
IPC: F16L27/08
Filed: 1983-02-18
Abstract: A rotary joint comprises two tubular rotary parts 1 and 2 and a stop in the form of a sleeve 9 of an internal diameter such as to enable it to receive the ends of the parts 1 and 2. The parts 1 and 2 are rotatable relative to each other and to the sleeve 9 about the axis of the sleeve. The ends of the parts 1 and 2 are shaped to form axially- extending stop lugs 4 and 5 and the sleeve 9 carries an inwardly-extending abutment or lug 10. When the ends of the parts 1 and 2 are located in the sleeve 9 the stop lugs 4 and 5 can move past one another but rotation of the parts 1 and 2 relative to the sleeve 9 causes the stop lugs 4 and 5 to engage the lug 10. Consequently, the parts 1 and 2 can be rotated through a full 360 DEG  in either direction relative to one another but continuous rotation in either direction is not possible. A spring pin 8 is located in the ends of the tubular parts 1 and 2 to exert a frictional force to resist rotation and enable the joint to support a load. The joint's properties make it particularly well suited to use in conduits for electrical cables. <IMAGE>

Title: Television receiver
Inventor: HUMPHRIES BRYAN JASON
IPC: H04N5/44
Filed: 1984-09-14
Abstract: In a television receiver the received video signal is processed to increase the displayed number of lines, e.g. by spot-wobble or line frequency doubling, so that each received pixel (1, 2, 3) produces two corresponding pixels to be displayed (4 to 10). The luminance values of two spatially adjacent pixels from different fields (e.g. 10 and 7), or the average luminance value of a group of pixels from one line and the luminance value of a spatially adjacent pixel from a different field are compared. The result of this comparison controls the degree of interpolation between one of the compared pixels (10) and the corresponding pixel in the previous line of the same field (5). If the compared pixels have the same luminance value then no interpolation occurs. <IMAGE>
