Title: Prevention of corrosion
Inventor: CHEEK PHILIP RICHARD
IPC: C23F15/00
Filed: 1986-04-05
Abstract: Corrosion in artifacts which are subjected e.g. to the effects of sea water can be prevented or arrested by immersing the artifact in a tank of solvent based corrosion preventative liquid, the tank also having one or more ultrasonic transducers. The operation of the transducers causes the liquid to penetrate the artifact to force out corrosion causing materials and to replace these materials with the corrosion preventative liquid. <IMAGE>

IPC: G03H1/24
Filed: 1986-07-16
Abstract: A holographic display means for displaying an image holographically embodied in a hologram 12, comprises (a) a hologram support for receiving and supporting a hologram 12 in a viewing position; (b) a reference light source 16 disposed adjacent the hologram support in a predetermined position such that light 22 emanating from the source 16 when energised cannot fall directly on to a hologram 12 supported on the support; and (c) a light reflecting means 24 disposed adjacent a boundary of the support and arranged to direct light from the source 16 onto a hologram 12 supported on the support so as to be incident on the hologram at a predetermined reference angle, which angle corresponds substantially to the angle of incidence relative to the hologram of a predetermined reference light used in producing that hologram. Preferably, light is reflected not more than twice before it becomes incident on the hologram, and advantageously, it is reflected only once. Reflecting surfaces may be planar, or curved in one or more directions.

Patent GB-2195400-A (GB)
Title: Heat engine incorporating a rotary vane device
Inventor: KERSHAW HERBERT ARTHUR
IPC: F04C23/00
Filed: 1986-09-29
Abstract: The rotary vane device functions simultaneously as a compressor and an expander. Fuel and air mixture compressed in the left-hand side 1 of the rotary device is ignited at 5 and the expanding gases are utilised in the right-hand side to drive the rotor 2. The gases are exhausted at 6 and pass via an optional venturi (Fig. 4) to a turbocharger 7 supplying scavenging and charging air through a port 8 into the device. Fuel is supplied by a pump 9 via an atomiser 10. An alternator 11 energises the ignitor 5. The inner wall of housing 1a contacted by the tips of vanes 3 is formed by a freely-rotatable ring (15, Fig. 5) mounted in a roller bearing (16). The pump 9 has an eccentrically-mounted rotary cylinder (19, Figs. 1 and 2) contacted by a stationary vane (23) separating the inlet and outlet (20, 22). In another embodiment (Fig. 6), the rotary device supplies compressed air to an external combustor (35) which supplies the working gases to drive the rotary device. The combustor may include a flash steam boiler (37) which instead supplies working steam to drive the rotary device, and the combustion gases are used instead to heat the boiler and are then supplied to an auxiliary turbine (38) or an auxiliary rotary vane expander (40). The combustor and boiler (35,37) may be replaced by a coal-burning steam boiler, the air compressed in the rotary device being carried round and mixed with the supplied working steam. <IMAGE>

Title: Device for detecting a component of an ambient gas
Inventor: STETTER JOSEPH ROBERT
IPC: G01N27/28
Filed: 1986-12-04
Abstract: A device for detecting a component of an ambient gas comprises conversion means (62,64) for chemically changing said component to a derivative product having a characteristic electrochemical activity, said conversion means having a means (64) for generating a signal when said component is present in a concentration above about 0.1 - 1.0%, but essentially unresponsive at concentrations below about 0.1%, and sensing means (74) responsive to the electrochemical activity of said product for concentrations of said component below about 0.1% for providing a signal indicative of the product and thereby the component. The conversion means may comprise a hot wire sensor having an oxidation catalytic surface of a noble metal and temperature controlled by controller (65) or it may be a metal oxide semiconductor sensor. Sensor means (74) may be an electrochemical sensor responsive to oxidised gases of organic compounds. If the conversion means (62,64) senses and indicates at (66) the presence of the component at concentrations above 0.1 - 1% then valve (70) directs the flow of derivative product away from sensor (74). When there is no signal from the conversion means the gas flow is to sensor (74). <IMAGE>

Abstract: A vehicle antilock braking system comprises a master cylinder (20) and a brake actuator (11) connected to the master cylinder (20) via a brake pressure modulator (23) which comprises a displacement piston (30) and a cut-off valve (38) controlled by movement of the displacement piston (30). The displacement piston (30) defines a first working chamber (34) connected to a fluid pressure source (44) and a second working chamber (33) selectively connected to the fluid pressure source (44) or to drain (54) via a solenoid changeover valve (48), the first working chamber (34) being connected to the second working chamber (33) via the solenoid changeover valve (48). A non-return valve (56) prevents flow from the second working chamber (33) to the first working chamber (34). The displacement piston (30) is arranged such that when the first and second chambers (34, 33) are connected to the fluid pressure source (44) a force will be applied to the piston (30) moving it to displace fluid to the brake actuator (11) and to open the cut-off valve (38), and when the second chamber (33) is connected to drain (54), pressure in the first chamber (34) will move the displacement piston (30) closing the cut-off valve (38) and permitting displacement of fluid from the brake actuator (11). <IMAGE>

Title: Compact control and display panels
Inventor: INOUE RYUZI
IPC: G06F3/0482
Filed: 1989-04-25
Abstract: Control panels for apparatus such as photocopiers, printers and facsimile equipment are made particularly compact by arranging for only a selection of the possible functions to be displayed or available for keyboard control at any one time. The choice of functions which are displayed/available is dependent upon the combinations of optional devices connected to the apparatus, eg type of document feeder, type of paper tray, attachment of finisher or sorter (Figs 2 and 30), and upon mode selection keys 308, 309, 310. Functions may be displayed in columns on screen 301 and are selected by action of cascade keys 319-1 to 319-5 associated with each column. Since it is not necessary for all functions/controls to be available simultaneously, the control and display panel can be made simpler with less clutter.
