Title: Improvements in or relating to power-assisted hydraulic master cylinders
IPC: B60T13/565
Filed: 1950-08-11
Abstract: 678,248. Hydraulic vehicle brakes. BENDIX AVIATION CORPORATION. Aug. 11, 1950 [Aug. 17, 1949], No. 20045/50. Class 103 (i). A power-assisted hydraulic master cylinder, of the type described in Specification 344,671, particularly for vehicle brakes, is designed for operation by a treadle and comprises improvements as regards the control value member, the liquid sealing and compensating arrangements, which provide a more compact unit. As shown in Fig. 2, the treadle has connected thereto a shaft 36 having a pivotal coupling with a slide valve member 84. The member 84 is slidable within the tubular portion 48 of the pressuretransmitting member 46 which moves with the piston 26 of the power cylinder 12. An annular land 92 on the member 84 divides two chambers 88 and 90 formed between the member and the tube 48. The chamber 88 communicates through ports 94 and 58 with the vacuum source of the power cylinder. The chamber 90 communicates through ports 96, the interior of the member 84 and ports 100 with the atmosphere. Thus the position of the land 92 relative to ports 106 leading into the power cylinder chamber 42 determines the pressure in this chamber, the power cylinder shown being of the " atmosphere suspended " type. The valve member 84 abuts against one end of a plunger member 82, the other end of which is hard against a diaphragm member 122 secured within the enlarged head 120 of the hydraulic cylinder plunger. The displacement of liquid by plunger 46 can thus be assisted by the movement of valve members 84, 82 against spring 146 so as to press out the diaphragm 122, the operator being able to " feel " the pressure generated in the hydraulic cylinder 24. A " wave " washer 112, Fig. 4, located between flange 56 of member 48 and flange 114 of member 84 provides a resistance that prevents the " hunting " by the valve member usually caused by a tendency to over-shoot its correct position. The valve member 134 between the reservoir 130 and the hydraulic cylinder 24 is of the type opened to allow a make-up of liquid by tilting by the rear face of the plunger head in its retracted position. It also opens automatically to allow make-up of liquid in the event of a vacuum being created in the cylinder 24. The check valve 158 is of the type, such as that described in Specification 305,994, [Class 103 (i)], which maintains a residual pressure in the pipe-lines leading to the brake cylinders.

Abstract: 1,204,234. Logic circuits for sorting articles. ARBEITSSTELLE FUR MOLEKULARELEKTRONIK. 26 April, 1968, No. 20067/68. Heading G4H. An article is sorted into one of a number of classes in accordance with a good/bad evaluation of each of a plurality of characteristics of the article, each evaluation being supplied as a single binary signal on terminal X2 and being compared with a series of reference signals on terminals X<SP>1</SP> 1 -X<SP>10</SP> 1  indicating whether a good or bad evaluation is required for the corresponding classification. As described the articles are to be sorted with ten classes. For each class there is a companion circuit I-X, a bi-stable F 1 -F 10  and an AND gate T 1 -T 10 . The comparison circuits each comprise a pair of AND gates and an OR gate connected so that if the two inputs are the same the output is "0" and if different, " 1 ". If the evaluation signal on terminal X2 agrees with the reference signal a "0" is produced and the corresponding bistable remains unset. If the signals differ the corresponding bi-stable is set. The evaluation signals relating to a succession of tests are applied to terminal X2 and, by the end of a test cycle, only one of the bi-stables remains unset indicating the class to which the article belongs. At the end of the test cycle gates T 1 -T 10  open to allow the set bi-stables to operate the associated sorting relays. Only one of the relays G 1 -G 10  remains unoperated. If any characteristic of the article is not to be used in the classification a bi-stable is provided which when set closes a gate to prevent the corresponding input signal reaching the comparator.

Title: Improved direct-viewing storage tube
Inventor: SMITH HENRY MILLARD
IPC: H01J31/18
Filed: 1955-07-12
Abstract: 780,391. Storage tubes. HUGHES AIRCRAFT CO. July 12, 1955, No. 20169/55. Class 39(1). A direct viewing storage tube has a positiveion repelling grid between the flooding electron source and the collector grid. The storage assembly comprises a metal ring 130 supporting an electroformed nickel screen 132 having a coating 134 of dielectric material e.g. talc, on one side, applied by spraying whilst air is forced through the interstices. On the other side is sprayed a thin layer of metal 136. The collector electrode 138 held in a bent-over annular electrode 140 is disposed in contact with the dielectric coating 134, the meshes of the screen 142 being at an angle to the meshes of the screen 132 to minimize the moire effect. The ion grid 22 extends across the storage assembly and is a stocking knit tungsten screen held tautly across a metal ring 150 which is welded to an annular electrode 154, the whole assembly being supported on insulating rods 156, 158. The ion repeller grid has a potential positive to the collector electrode and eliminates ions formed by the flood gun electrons on the residual gases of the tube. It behaves also as a shield eliminating potential variations within the tube and may function as an auxiliary collector grid during erasure. In operation a scanning gun lays down a charge pattern, the elemental areas being charged by the beam of a flood gun to an upper or lower value of charge which influences the passage of flood electrons to the viewing screen. The charge is erased by raising the potential of the collector grid. Specification 758,677 is referred to.

Abstract: 803,234. Gasefying solid carbonaceous fuels. GAS COUNCIL, WEST MIDLANDS GAS BOARD, DENT, F. J., and STUART, R. T. Nov. 5, 1954 [July 28, 1953], No. 20957/53. Class 55 (1). In a process for gasefying particulate solid fuels by entraining them in a stream of air or oxygen, and steam and operated at such a temperature that liquid slag is produced, the gases formed are cooled by injecting into them particulate carbonaceous material in a proportion sufficient to cool the gases, the carbonaceous material is separated from the gases, cooled by partially reacting it with steam and/or carbon dioxide in a separate vessel and reintroduced into the hot gases. As shown in the drawing, particulate fuel, steam and oxygen are injected by lines 1, 2 and 3 respectively into an elongated zone 4 in the lower part of which the fuel is gasefied, liquid slag being withdrawn at 5. Carbonaceous material is added to the gases at 9 and is separated from the cooled gases in cyclone 11, the gases leave by outlet 12 and the separated material passes to a fluidized zone 6 in which it is cooled by reaction with steam and/or carbon dioxide admitted at 8. Gas produced in zone 6 plus excess steam and/or carbon dioxide are used as gasefying agents in the gasefication in zone 4. Fresh carbonaceous material is added to zone 6 by pipe 16 and excess material may be added to supply some preheated carbonaceous material for gasefication in the lower part of zone 4. Heat exchange between the hot gases from zone 4 and the steam and/or carbon dioxide for zone 6 or the air for zone 4 when air is used may be arranged. The gasefication may be effected at pressures up to 20 atmospheres and the gases are cooled from about 1300‹ C. at the point where the cooling carbonaceous material is introduced to about 800-850‹ C. in leaving the system.
