Patent GB-705483-A (GB)
Title: Improvements in electrical information storage means
Inventor: WILLIAMS FREDERIC CALLAND
IPC: H01J31/60
Filed: 1949-06-07
Abstract: 705,483. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 19, 1950 [June 7, 1949], No. 15188/49. Class 106 (1). [Also in Group XL(c)] An information storage device of the type in which an electric charge-retaining surface within the envelope of a cathode-ray tube is scanned by the electron beam to set up on the surface charges representing the information to be stored, comprises means for sweeping the beam along a line over the surface, means for intensifying the beam in order to produce on the surface a first state of charge representative of one item of information, and means for deflecting the beam in a direction inclined to the direction of sweeping whilst it is intensified in order to produce on the surface a second state of charge representative of another item of information. Specifications 645,691, 657,591, 682,156 and 705,474 are referred to. The X scan waveform, Fig. 2 (e), contains steps of constant voltage causing the beam to pause for the duration of each dash pulse ; a waveform, Fig. 2 (f), superimposed on the Y scan waveform causes a deflection in the Y direction during this period. Thus, when a digit "0" is recorded (Fig. 2 (a)) during a "dot" pulse, Fig. 2 (c), there is only a slight movement in the Y direction, but when a digit "1" is recorded (Fig. 2 (b)) during a "dash" pulse, Fig. 2 (d), the beam is deflected in the Y direction by the maximum amount; this may be at right angles or at an acute angle to the X scan direction. The transient signals generated in the pick-up electrode when the traces, Fig. 2 (a) and Fig. 2 (b), are subsequently scanned by the electron beam, shown in Figs. 2 (g) and 2 (h) respectively are applied at a terminal 33 of a gate circuit, Fig. 3, strobe pulses, Fig. 2 (i) being applied via a diode D11. When a positive (digit "I") signal arrives at the terminal 33 a negative pulse is developed at the anode of the normally non-conducting valve VII, causing the grid of a cathode-follower V12 to be driven negative and held there until the termination of a negative-going "dash" pulse at the anode of a diode D15. Thus an input "dot" pulse at the grid of a valve VI 3 is extended to form a " dash pulse signal which is transmitted via cathode-follower V14 to the CRT grid.

IPC: F02K7/06
Filed: 1939-05-22
Abstract: 522,935. Generating combustion products under pressure; propelling ships. WEISZ, H., and LICHTENSTEIN, E. May 22, 1939, No. 15189. [Class 51 (i)] [Also in Group XXXIII] Combustion products are generated under pressure for power purposes, such as the propulsion of ships &c. by admitting to a combustion chamber 1 compressed air or oxygen and hydrogen or other fuel through pipes having non- return valves and inlet-nozzles which are closed in timed, relation with a spark ignition. The combustion chamber 1 is water jacketed and provided with 'a spring loaded exhaust valve 4. Pipes 9, 9a admit air or oxygen and gaseous fuel through nozzles 10, 10a and spring loaded non- return valves 11', 11a. The nozzles 10 10a are opened and closed by spring pressed levers 12, 12a having armatures 14, 14a opposite the ends of the core of an electromagnet 15. As the contact arm 21 of a rotary distributor 20 rotates it first makes contact with the segment 22 to close the circuit through the electromagnet and open the nozzles 10, 10a to admit gases to the combustion chamber and then makes contact with the segment 23 to energize the sparking plug 24, the nozzles 10, 10a and'valves 11, 11a being previously closed. As shown in Fig. 2, the exhaust gases from the chamber 1 may be led to a tube 8<SP>1</SP> arranged at the bottom of a ship 26 for propulsion purposes. The tube 8<SP>1</SP> may be provided with a non-return valve 27. In submarine vessels a non-return valve may also be arranged in front of the valve 4.

Filed: 1916-10-25
Abstract: 126,016. Coote, R. A., and Hartley, A. C. Oct. 25, 1916. Machine guns; fire between aircraft propeller blades, controlling.-Relates to interrupter devices of the kind which operate to fire the gun and automatically cease to do so when an object, such as an aircraft propeller blade, is in the line of fire. According to the invention, the interrupter gear not only operates through intermediary members to fire the gun, but also acts positively to set the intermediary members to interrupt the firing of the gun. The invention is shown applied to the usual trigger-bar f of a Vickers gun. The interrupter motor a connected with the propeller-shaft of an aircraft engine, has its plunger b positively connected by a lever d to the trigger-bar f through a slot c<1> in the plunger and a fork d' engaging a projection on the trigger-bar. The plunger b of the interrupter motor is periodically advanced and an inflammable fuse head r' on the bomb is propeller-shaft, and firing is permitted or effected when the trigger-bar is drawn to the rear, and prevented when the bar is advanced. Fig. 3 shows a modification in which the interrupter gear comprises a piston b bearing against a spring- controlled shaft g having a bent rod n which takes the place of the trigger-bar of the former construction. Reference has been directed by the Comptroller to Specifications 23790/14, 127,320, and 129,299.

Title: Improvements in and relating to the treatment of textile and other fibrous materialsto protect them from attack by or render them unsuitable as a habitation for insects
IPC: A01N25/04
Filed: 1948-06-07
Abstract: Textile and other fibrous materials are protected from attack by insects or rendered unsuitable as a habitation for them by treatment with an aqueous dispersion containing an insecticide of the general <FORM:0650403/VI/1> formula (where X represents chlorine or bromine and R represents a benzine ring unclearly substituted in the para position by a halogen, alkyl or alkoxy group), as the disperse phase, which latter is positively charged by the presence of casein or blood albumen associated with sufficient of an organic acid to bring the pH of the dispersion below the iso-electric point of the casein or blood albumen respectively.  The insecticide is first dissolved in a solvent, e.g. benzene, xylene, methyl cyclohexanone, or ethyl acetate, and the solution rendered polar by the addition of a fatty acid having more than 12 carbon atoms in its molecule, e.g. oleic acid.  It is then dispersed in an aqueous solution of casein or blood albumen which has been prepared by dissolving the protein in an alkaline solution and then adding an organis acid to bring the pH finally to 3.5 to 4.5.  The dispersion may be applied to the textiles by spraying or padding, the excess squeezed out, and the materials dried.  In examples, wool in the form of piece, hank or cheese, after an acid dyeing process, cellulosic or vegetable fibres in yarn or piece form, or garments of wool or cotton or mixtures thereof are treated with the insecticide dispersions diluted with cold water. Exhaustion of the bath may be speeded by the addition of Glauber's salt in the case of wool, or by heating the both in that of cellulosic fibres.  Specifications 590,826 and 603,428, [both in Group VIII], are referred to.
Patent GB-1593361-A (GB)
Title: Control system for regulating large capacity rotating machinery
IPC: F04D27/00
Filed: 1978-04-18
Abstract: The control system of the invention regulates a centrifugal compressor having inlet guide vanes adjustable as one means for varying the compressor capacity.  A variable speed motor is connected to drive the compressor, and provides another means for regulating the compressor capacity.  The control system regulates the motor speed alone over one portion of the load variation curve, and regulates the motor speed jointly with the inlet guide vane opening over another portion of the load variation curve, to achieve the most energy-efficient operating condition while avoiding the surge condition.  This optimum control path is realized by utilizing a signal which is a measure of the compressor head value.  Compressor surge or instability is avoided by deriving a critical Mach number (speed indication) for any given operating condition, as a function of the compressor head and vane position, and preventing the motor speed from going below that Mach number under the specific operating conditions. The control system of the invention is useful both with existing equipment, by way of retrofit, and with newly manufactured and installed equipment.
