Title: Circuit for cold cathode tube display
Inventor: JACKSON THOMAS MEIRION
IPC: G09F9/313
Filed: 1959-04-09
Abstract: 912,385. Monogrammic signs. STANDARD TELEPHONES & CABLES Ltd. April 8, 1960 [April 9, 1959], No. 11968/59. Class 118. In a monogrammic sign comprising a number of cold cathode tubes, or anode-cathode elements in a single tube, arranged in a coordinate array and primed cyclically, a number of rectifiers connected to the cathodes (or anodes) are connected to a common input point and a series of pulses representative of the character to be displayed are fed into this point, the circuit being such that only a primed tube is affected by a character pulse and thereby caused to glow. The individual cathode elements 13 are arranged in rows 1-5 and are connected through 500 K# resistors 15-19 to terminals 20-24, while the rows of anodes 6-12 are connected to terminals 32-38. Specification 905,353 describes an appropriate form of tube construction. Rectifiers 25-29 join the cathodes 1-5 through a 5K# resistor to a common input terminal 31. A " slow scanning " pulse of 100V. is applied to terminal 32 while the cathodes, normally biased at 50V., receive in turn " fast scanning " pulses of - 100V. When all the cathodes have received the - 100V. pulse, the +100V. pulse is transferred from terminal 32 to terminal 33 and the cathode pulsing is repeated. The cycle is repeated at each anode. When the elements of an anode-cathode cross-over are at + 100V, - 100V. respectively, a current of about 0.1 mA flows across the cross-over, i.e. it is primed. If now a series of predetermined - 100V. character pulses are applied to input terminal 31, the current through a primed cross-over increases to 10 mA and a glowdischarge occurs, all the other cross-overs remaining non-conducting. The priming cycle and the character pulses are repeated fast enough to give an overall impression of the display pattern required.

Title: Improvements in or relating to fluid pressure brake mechanism for motor road and other vehicles
IPC: B60T13/12
Filed: 1926-05-11
Abstract: 275,718. Cross, D. H. May 11, 1926. Fluid-pressure; hand, foot, and personal actuation.-In a fluid-pressure brake mechanism for motor and other vehicles the brake operating piston 3 works within a sleeve valve 2 in a cylinder, movement of the sleeve valve preventing free circulation of fluid so that it acts on the piston to apply the brakes. Movement of the foot-pedal is arranged to apply the brakes in the event of failure of the mechanism. Oil normally circulates through a duct 17 formed in the cylinder head into the sleeve valve and through an aperture 5 in the sleeve valve into a longitudinal duct 6 in the cylinder and returns to the oil pump by a pipe 7. On movement of the sleeve valve by a pedal 31, an adjustable link 29 and a rod 9, the aperture 5 is closed by the piston 3, which is thereupon forced along the sleeve by the consequent fluid pressure generated. The cylinder head is provided with an extension 16 which protrudes into the sleeve valve to such an extent that the open end of the valve is always closed by this extension. The extension carries a relief valve 18 provided with an adjustable spring and communicating with a duct 21 which is open to the duct 6 when the sleeve valve is moved outwardly. A groove 27 allows leakage of oil past the sleeve valve to permit full return of the sleeve valve. The apertures in the end of the cylinder through which pass the piston-rod 8 and the rod 9 are packed by a felt washer 11 over which is secured a plate. An aperture 14 is provided in the closed end of the sleeve valve to relieve back pressure on the piston. The foot lever 31 is formed on a sleeve 32 mounted on a rod 33 on which is also mounted a sleeve 35 formed with a lever 37 connected to the brakes and a lever 36 contacted bv a roller on the end of the piston-rod 8. The sleeves are formed with dogs 34, 38 adapted to cooperate after the foot lever has moved a certain distance and allow the brakes to be directly operated. The sleeve valve may be operated by a lever on the dashboard which may be locked in position and an indicator for the brake pressures may be provided.

Title: Improvements in or relating to the manufacture of foamed polyurethanes
Inventor: WOOD JOHN FRANCIS
IPC: C08J9/02
Filed: 1963-03-27
Abstract: Foamed polyurethane materials may be produced by the reaction of an organic polyisocyanate with an organic polyhydroxy compound and not more than 2.5% of water based on the weight of polyhydroxy compound, heat from an external source being applied to the reaction mixture, thereby raising the maximum temperature attained within the foamed polyurethane to not less than 120 DEG  C. In an example, a foamed polyurethane material is made by mixing a glycol/propylene oxide condensate with a mixture of tolylene 2 : 4- and 2 : 6-diisocyanates, water, triethylenediamine, N,N-dimethylphenylethylamine and a siloxane-oxyalkylene block copolymer and heating to 80 DEG  C. by microwaves.  The blend is then poured into a mould and further heated by infra-red radiation to a temperature of 140 DEG  C.  Suitable polyhydroxy compounds are polyesters, polyesteramides, polyethers and non-polymeric oxyalkylation products of active hydrogen containing compounds. Catalysts, blowing agents, fillers, flame-retardants and colouring matters may also be added.

Title: Method and apparatus for pumping fluids
IPC: F04B19/12
Filed: 1972-03-16
Abstract: 1427723 Rotary sprengel pumps MICRO-D Ltd 15 June 1973 [16 March 1972] 12252/72 Heading F1C A method of pumping fluids comprises continually forming U-tube manometers to replace U-tube manometers being continually destroyed to maintain in existence a series of inter-connected U-tube manometers opposing a head of fluid. The pump shown comprises a helically coiled tube 5 supported on a cylinder 1 carried by a hollow shaft 2 which is rotated by a handle 11. For approximately half of each revolution, the open end of the coil 5 dips into a body of water, while for the remainder of each revolution, the open end is above the water level. Consequently, the lower part of each turn of the coil contains water while the upper part contains air, whereby the air is pumped along the coil by a succession of U-tube manometers of water. The discharge end of the coil is connected at 7 to a radial pipe 8 leading to the hollow shaft 2, whence the water and air are discharged via a rotary seal 9 to a stationary pipe 10 or directly to a rotating pipe. The coil may be self-supporting or may comprise several layers or be of helical or beehive form, or may be replaced by a conduit following the form of a coil but integral with the supporting structure. Changes in radial distance from the axis of rotation are compensated for by changes in the cross-sectional area of the tube, whereby the volume per degree of air remains substantially constant. The cross-sectional area may be reduced over a region at approximately one-third of the overall length from the intake end. The pump may comprise several stages, some of the liquid being removed in a separation chamber between stages to compensate for the reduction of volume of the gas during compression. Fluid discharged by the pump or removed between stages may be used to drive a hydraulic or air motor or a turbine which assists in driving the pump. The intake to the coil need not be at atmospheric pressure. Both intake and discharge may take place at annular or circular chambers situated at either end of the coil. The tube or other conduit may be a flexible coil running over two or more rollers rather than revolving about a single axis.
