Patent GB-2243047-A (GB)
Title: A digital composite video encoder
Inventor: WEDDERBURN-BISSHOP THOMAS
IPC: H04N9/65
Filed: 1991-04-04
Abstract: Input digital luma and chroma video signals encoded in accordance with CCIR Recs. 601/656 are encoded into a composite analogue output signal of desired format, e.g. PAL or NTSC. A phase calculator 27 determines the subcarrier phase at each position along each line, and this phase value together with the chrominance values are used to address lookup tables 26. The outputs of the lookup tables are applied to DACs 29 and combined and filtered 30. The resultant is further combined with the output of a DAC 22 receiving the luminance signal and with information from a sync. pulse input 44 in a combining and filtering circuit 31. The lockup tables 26 are reprogrammable and other parts of the encoder suitably controllable to allow a variety of composite output formats to be generated. As most of the circuitry operates in the digital domain, the need for setting-up adjustments and the problems of component ageing are minimised. <IMAGE>

Abstract: Air is supplied to a clean room by an inlet housing (duct) 2 including a fan unit 3 and an outlet housing 4 connected to the inlet housing 2. The inlet housing 2 comprises an inlet framework (15 fig 3) and panels 16 sealed to the framework to prevent ingress of air or particles of dust through the joint between the framework elements and the panels 16. Longitudinal and transverse inlet frame members (21, 22, 23, 24) and intermediate inlet frame members (47) have sidewardly extending inner flanges 45, (46) against which inlet panels 16 are drawn. Longitudinal and transverse outlet frame members (52, 53, 54, 55) and intermediate outlet frame members (65) have sidewardly extending outer flanges (61, 69) against which outlet panels 16 are pushed for sealing engagement to prevent egress of conditioned air downstream of the fan 3.

Title: Sound responsive light blinking device
Inventor: HATA SHUJI
IPC: H05B37/02
Filed: 1992-04-27
Abstract: There is described a light blinking device which is capable of accurately and precisely blinking illuminants in response to music. The device includes a plurality of channels, each having a buffer amplifier 10, a phase lock loop circuit 11 having a lock state detecting circuit (11d), (Fig 2) which generates a digital output signal, a time constant circuit 12, an output circuit 13 and a decorative illuminant 14 which is turned on by an output from the output circuit 13. A common input terminal In receives an audio frequency signal, eg. from a microphone incorporated into the device. The free-running frequencies and capture ranges of the PLL circuits 11 of each of the channels are arbitrarily set to within the audio frequency range so that the free-running frequencies and the capture ranges do not substantially overlap one another. The time constant circuits 12 operate to integrate the output signals from the lock state detecting circuits in the PLL circuits 11 so as to obtain a stable signal which operates the output circuits 13 to turn on the respective illuminants 14. Additional external illuminants, and motors for operating movable displays, may be connected in parallel with the illuminants 14. <IMAGE>

Title: Liquid level sensor
Inventor: PARDY RONALD PETER
IPC: G01F23/24
Filed: 1992-06-29
Abstract: A liquid level sensor e.g. for a vehicle fuel tank has two side by side plates 20, 22 insulated from each other by a spacer 24 and which extend vertically into the liquid. Both plates have conducting surfaces and one plate has laterally extending teeth 26. The teeth are constructed, for example from bi-metallic material, so that when they cool to below a certain temperature, they bend (Figure 5) and contact is made between the two plates (to complete an electrical circuit) at a point dependent on the liquid level. The position at which contact is made can determine the current which flows in an electrical circuit so that an indication of fuel level can be obtained. As shown the plate 20 carries a resistive track 28, but the placing of resistor elements on the teeth 26 is alternatively envisaged. <IMAGE>

Title: A sealant
Inventor: SMITH HENRY ROY
IPC: F16J15/12
Filed: 1995-01-05
Abstract: A sealant comprises a matrix of flexible material embedded in which are frangible elements inert to the matrix material. The matrix material may be selected from acrylonitrile copolymers, polyvinyl alcohols, polyurethanes, silicones and acrylonitrile-butiedene-styrene terpolymer. The frangible elements may be hollow spheres with a diameter of between 20 and 200 microns and a density of 0.1 to 2.4 g/cc. Particles of other materials having relatively high thermal conductivity may be included in the matrix material. A gasket sealing arrangement provides the sealant as a coating for an electrically conductive gasket in the form of an aluminium sheet with protrusions extending away from each major surface thereof, the arrangement being that on application of pressure the protrusions extend through the matrix material to electrically contact the surfaces between which the arrangement is placed. A method of locating a conductive sealing gasket between an antenna base and an airframe is described.

Title: Valve timing control system
Inventor: ADACHI MICHIO
IPC: F01L1/34
Filed: 1995-02-06
Abstract: In a valve timing control system, the relative phase of the camshaft 5A, 5B with respect to the crankshaft 2 is controlled to a target value. The effects of variations in the angular speed of the cam resulting from its interaction with the valves as it rotates are removed prior to the phase control being effected. The effect of this variation can either be removed electrically by deriving a phase compensation factor dependent upon the position of each of the cam rotation sensors (51A, 51B, 52A, 52B in figure 4) prior to effecting the phase control or it can be removed mechanically by locating the cam rotation sensors so that they are not subject to the effects of the angular speed variation of the cam. <IMAGE>
