Title: Banner towing device
Inventor: HEMMING NICHOLAS FRANCIS
IPC: G09F17/00
Filed: 1982-07-20
Abstract: This invention relates to a towing device for an aircraft towable banner. The towing device 10 comprises a lead pole 11, which extends over the height of the device and which trails spaced nylon braid strips 12. The strips 12 each carry a retaining clip 14 at their free ends for engaging the banner. The lead pole has a circular strip 18 at its load end for carrying weighting washers, which serve to hold the lead pole 11 normally upright during flight. A rudder 20 is attached to the lead pole 11 adjacent the weights and it can be rotably adjusted about the lead pole axis to determine the orientation relative to the vertical of the lead pole and hence the trailing banner in flight. <IMAGE>

Title: Apparatus and method for modifying the dynamic interaction between a fluid and a object
Inventor: ROEBUCK IAN
IPC: B63B1/36
Filed: 1983-01-19
Abstract: The drag and surface noise effects experienced by a body moving through a fluid are reduced by providing over at least part of the body a flexible surface membrane (50) and means for establishing a transverse displacement wave pattern in the membrane whereby stable longitudinally rolling vortices may be entrained in the wave pattern. The wave pattern is produced by the action of pistons 52 when, with zero longitudinal velocity of the surface, the phase velocity of the transverse wave is made approximately half of the fluid flow velocity. Similar wave motion can be produced by actuating the leading and trailing edges of the surface membrane or by producing transverse waves in a second fluid adjacent the surface and remotely from the fluid flow. Alternatively the wave pattern and vortices may be made stationary relative to the body by moving the surface membrane in the opposite sense to the fluid flow over and under a series of alternative rollers and wheels. <IMAGE>

IPC: G11C7/24
Filed: 1983-03-24
Abstract: A memory system comprises a main memory 2 and means, such as a selectable buffer 31, for preventing illicit reading of the memory 2.

Title: Device for removing electrolyte from electrochemical cell exhaust gases
Inventor: JOHNSON CARL KENNETH
IPC: H01M8/04
Filed: 1983-08-15
Abstract: Phosphoric acid electrolyte in the exhaust gas of a fuel cell (10) is removed in a device comprising a heat exchanger (34) which reduces the temperature of the gas to below the acid condensation point, followed by an accumulator (36) including a plurality of vertically oriented, spaced apart, open porosity plates (52) which pick up the acid as the gas stream flows between the plates.

Title: Fluid valve position sensor
Inventor: OLIVER MICHAEL RODERICK
IPC: G01B11/14
Filed: 1984-06-09
Abstract: A fluid valve comprising a valve member 20 movable relatively to a valve seat 10 through a range of positions between a valve fully open position and a valve closed position by pressure of the fluid applied to the valve. A light conducting path is defined through the valve from a light input end 52 to an output end 60. Light is transmitted along the light conducting path and a non-electrically operable device 42,66 is provided to vary the proportion of the light delivered to the input end which is transmitted to the output end. The amount of light transmitted is varied in accordance with the position of the valve member so that the amount of light delivered to the output end is a function of the position of the valve member relative to the seat. In other embodiments, light transmission is varied by varying the length of an optical path separating the ends of two fibre-optic cables. <IMAGE>

Patent GB-2153128-A (GB)
Title: Token handling device
Inventor: EGLISE DAVID
IPC: G06K7/00
Filed: 1984-10-04
Abstract: A token handling device transmits, using an electromagnetic carrier, data, clock pulses and power to a token. The token transmits data by varying the degree of absorption of the carrier in synchronism with the clock pulses. These data transmissions are detected by a receiver in the token handling device, the sensitivity of which is adjusted each time a token is received. The token could be used in transactions in place of coins, or alternatively could be used for identification purposes in other areas. Data stored by the token could be used to change the way in which the token handling device operates. The token handling device may for example form a vending machine, and the token could be used to alter the pricing of goods vended thereby. The token handling device may be combined with a coin validator, in which case there is preferably a common path from an entrance slot for carrying both the tokens and the coins to appropriate testing apparatus. <IMAGE>

Title: Dispensing closure
Inventor: DROBISH JAMES LEE
IPC: B05C11/00
Filed: 1984-10-26
Abstract: An externally mounted integral, self-sealing check valve dispensing closure for use in a fluid product dispenser is of a resilient plastics or elastomer having a durometer between 10 Shore A and 95 Shore A and has a wall thickness of 0.25 to 1.3 mm. The closure converges along an inflexed non-planar surface 20, 220 to a normally closed discharge slit which may be curved (Fig 1) or branched (Fig 9). The edge of the inflexed non-planar surface mates with at least one other, oppositely disposed surface to form the discharge slit, with these mating surfaces having substantially flat lands of contact along the slit. The inflexed non-planar surface forms an acute angle at the slit with any line drawn through the slit parallel to the central axis of the closure and is adapted to resiliently deflect outwardly in response to the application of product pressure from within, thereby opening the closure and permitting product flow therethrough. <IMAGE>

Title: Gas valves
Inventor: VIZOR REGINALD DENNIS
IPC: F24C3/12
Filed: 1985-12-18
Abstract: A control valve assembly for a gas cooker having a lid to close down onto the burners when out of use, has a valve 28, 24, 22, closable by the lowered lid to prevent gas flow from inlet 10 to outlet 12 leading to the taps through main throat 16 and bleed passage 40, so as to terminate the burner flames when the lid is down, and a valve 30 to prevent the gas flow being re-established when the lid is lifted if any of the appliance taps have been left on. Valve 30 is held open by mains gas pressure, and closed by spring 36 if pressure on the outlet side acting on enlarged area 32, 34 falls towards ambient atmospheric pressure, for example because a tap is left on. When the tap is closed, bleed via passage 40 builds up pressure on area 32, 34 so that together with pressure within throat 16 the valve 30 is re-opened. <IMAGE>

Title: Heating method for burner
Inventor: MULCAHY KEVIN LAURENCE COOPER
IPC: F27D99/00
Filed: 1986-04-18
Abstract: A billet 52 is heated in a furnace 50 by hot gases from a burner 10 fired by natural gas fed via a valve 64. Primary air is fed via a valve 62 from a fan which also feeds supplementary air. The gas and primary air are in stoichiometric proportions. Supplementary air mixes with the heated flow from the combustion chamber to give a cooled flow of 750 DEG C or less. The rates of flow of the gas and primary air are controlled by the valves 60, 62 and by a controller 66 so as to reduce to zero the difference between a temperature in the furnace sensed at 68 and a desired temperature set in the control system 66. In modifications (i) the supplementary air flow rate is controlled by the controller in addition to, or instead of, the gas and primary air (ii) the gas or primary air or each is individually controllable. <IMAGE>
