Title: Yaw control of aircraft and missiles
Inventor: HEYDARI FARIBORZE
IPC: B64C21/00
Filed: 1989-05-26
Abstract: A yaw control system for an aircraft or a missile intended to be flown at considerable angles of incidence, the system comprising means for drawing air into the aircraft body through one or more pairs of orifices located close to the nose of the aircraft, the orifices of the or each pair being located above the line of vortex shedding and symmetrically about the windward generator. By drawing air into such orifices, the generation and sequential shedding of vortices of alternating senses is inhibited to a degree dependent on the amount of air being drawn in, and the consequent control of the yaw forces induced by such vortex shedding provides a means of steering or stabilising the flight of the aircraft or missile. Respective holes 10 on opposite sides of nose 8 are connected by tubes 13, 14 to valve 15, 16 which control the application of suction to the respective holes 10. <IMAGE>

Title: Digital video effects generator
Inventor: WOODHAM DAVID J
IPC: H04N5/272
Filed: 1992-04-13
Abstract: A digital video effects generator includes a circuit (44) for increasing the effective sampling frequency of the digital video component signals prior to their spatial transformation and linear interpolation, thereby reducing losses due to the (sin x)/x frequency response of the sampled video signal. The generator provides for spatially-mapping video motion data (42, 66) representing the degree of video data motion between temporally adjacent video frames, and for motion adaptive interpolation. Pre-transform keying (38) allows two video signal transformations to be keyed simultaneously; and selectively transforming (60, 62, 64) portions of input video signals allows selective keying of non-spatially transformed video into selected regions of the video image. The generator also allows for selectively linking keyframes within separate effects and providing smooth parametric transitions therebetween, thereby allowing several separate effects to be combined into a single effect with smooth parametric transitions between the linked keyframes, and for maintaining "pinned" image corners during parametric transitions between keyframes. <IMAGE>

Title: Cooling superheated vapour refrigerant
Inventor: HYDE ROBERT EDWARD
IPC: F24F3/153
Filed: 1992-05-29
Abstract: Liquid pressure amplification with superheat suppression is used in an air-conditioning or refrigeration system which includes a compressor (12), a condenser (14), an expansion valve (16), and an evaporator (18), interconnected by conduits in a closed refrigerant loop. A first conduit (13) couples an outlet of the compressor to an inlet to the condenser. A centrifugal pump (32) is coupled to the condenser (or receiver) outlet for boosting the pressure of the condensed liquid refrigerant by a substantially constant increment. A second conduit (15) transmits a first portion of the condensed liquid refrigerant from outlet of the pump through the expansion valve into the evaporator to effect cooling. A third conduit (34) transmits a second portion of the condensed liquid refrigerant from the pump outlet into the condenser inlet, which cools the superheated vapor refrigerant entering the condenser, reducing head pressure. <IMAGE>
