Patent GB-2215815-A (GB)
Title: Fluid control valve
Inventor: WOOD ANTONY JOHN
IPC: F16K11/07
Filed: 1988-03-26
Abstract: A fluid control valve has a spool 10 mounted within a cylindrical sleeve 12, and a plurality of ports distributed along the longitudinal axis of the spool, there being a constituent sleeve portion 12A, 12B both between each adjacent pair of ports, and in which each valve port is formed. There is an adjacent pair of ports, such as a service port 22b and a return port 24b, arranged such that when the service port is shut off by a spool land 23 there is a spool chamber 29 extending from the land to the return port, at the same fluid pressure as in the return port, and there is relatively high fluid pressure in the shut off service port. O-ring seals 16 are provided between the sleeve and the valve body 15 and different fluid pressures, at different points along the sleeve, compress the seals. In order to reduce the tendency of the sleeve to flex, the sleeve portion extending between the return and service ports is provided with a reduced thickness part 30 contiguous with the service port, and an O-ring may be provided between the reduced thickness sleeve part and the valve body; and/or an O-ring extends in a plane including the control edge of the spool land when closing the service port. <IMAGE>

Title: Chronoscopes
Inventor: CHILDS MICHAEL ANTHONY
IPC: G01P3/68
Filed: 1988-11-15
Abstract: A chronoscope has two transmitter detector pairs 10, 12 spaced apart by a known distance to permit the determination of the velocity of a projectile fired sequentially through the spaced beams 11 of radiation from the two transmitters 10 and falling on the associated detectors 12 by timing the interval between the detected falls in received radiation. The chronoscope has a self-checking function obtained by a precision second timer 17, 18 providing outputs at a pre-set interval to reduce the radiation transmitted initially by the first transmitter and then by the second transmitter. The detected time interval between the falls in received radiations is then compared with the pre-set time interval output by the second timer. <IMAGE>

Title: Manufacturing an insulating panel
Inventor: MCCARTHY EOIN T
IPC: E04C2/292
Filed: 1989-01-27
Abstract: An insulated panel 1 comprising a profiled external skin 2, an internal backing tray 3 and an insulating core 4 is manufactured by laying the external skin 2 down and making overlapping indicating marks 15, 16. A trailing edge of the external skin 20 of a preceding panel in a line is lifted and placed down on the leading edge of the panel 1 and a joint made by an adhesive tape 25. Liquid foam reactants are applied to the skin 2 through nozzles 35 and is then covered by a backing tray 3 (Figure 4 - not shown). The skin 2 and tray 3 with liquid reactants is then passed through an oven where the foam reactants expand to fill the space between the skin 2 and tray 3 with a foam core 4. At a first cutting station a cross cut saw 50 partially cuts through the backing tray 3 and foam core 4 at the joint between the external skins 1, 20 and the cutting is completed by a manually operated second saw 60 (Figure 11 - not shown). Clean overlap between the panel 1 prevents ingress of water at overlapping joints in use. <IMAGE>

Title: Converting field rate of telecine signal
Inventor: CLAYTON JOHN CHRISTOPHER
IPC: H04N7/01
Filed: 1990-03-13
Abstract: A video signal so derived from cine film recorded at a lower frame rate that each video field is produced from an individual cine frame (e.g. an NTSC 525/60 field signal from a film recorded at 24 frames/sec, each five field block divided 3:2 to a pair of cine frames) undergoes standards conversion including a change in field rate such as to maintain the individual cine frame to video field relation. As shown the NTSC signal is converted to an intermediate 625/48 PAL standard with a modified sub-carrier frequency (2 fields for each cine frame) which is buffered, e.g. on a modified tape recorder, and then read out at 50 fields/sec (on a normal recorder). Alternatively the NTSC signal is buffered and read out at 62.5 fields/sec, 2 fields/cine frame are selected (525/50 signal) and the selected signal converted to PAL format. PAL signals from film replayed at 25 frames/sec may be converted to NTSC. Detection of groups of fields relating to one cine frame and distinguishing cine from non-cine material are described. Non-cine material may undergo a motion adaptive 4 line 4 field interpolation; cine material interpolation occurs only between fields from the same cine frame. <IMAGE>
