Title: Information writing system for electrostatic storage tubes
IPC: H01J31/60
Filed: 1954-05-21
Abstract: 762,313. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MA. CHINES CORPORATION. May 21, 1954 [May 26, 1953], No. 14983/54. Class 106 (1). In a method of or system for writing information in a cathode-ray tube store having a beam control grid, a dielectric target and a backing- plate capacitatively coupled with the target, r.f. modulating voltages having a predetermined phase relationship are applied to the backing plate and to the grid. The storage system described comprises a cathode-ray tube similar to that described in Specification 762,314 in which binary digits are represented by charges on elemental areas of a dielectric target 3 capacitatively coupled to a backing- plate 6, the beam being directed to particular areas by deflection plates 5. The target assembly may be constructed as described in Specification 762,294, [Group XL (a)]. Writing.-A " 1 " is written on a selected target area by applying a negative pulse over lead 10, Figs. 1 and 2, and cutting off a normally conducting double triode 12 which controls an oscillator circuit including double triode 25. The latter then oscillates and produces a high frequency voltage (15 Mc/s.) across primary 15 of a transformer 16, the resultant voltage induced in secondary 35 being applied in opposed polarity to backing-plate 6 (see Fig. 1) and a barrier grid 8. The high-frequency voltage across 15 is applied also via conductor 57, condenser 58, the right half of cathode follower double triode 50, and delay line 53 to the C.R.T. control grid 4 (see Fig. 1), the delay being such that the grid 4 is positive when the backing plate 6 is negative, thus producing a positive change on the target area. Reading and regeneration.-This is effected by applying a positive pulse over lead 60, Figs. 1 and 2, via the left half of cathode follower 50 and the delay line 53 to the grid 4, thus switching on the beam. If a " 1 " or positive charge is stored on the selected target area, a negative pulse will be obtained from backing-plate 6. This pulse is applied via lead 36, recording winding 35 and lead 40 to an amplifier A (see Fig. 1) which produces an amplified negative pulse on output lead 100; this output may be used to control the tubes 12 and 25 in a regeneration cycle such as is described in Specification 762,314. The amplifier (Fig. 3, not shown), comprising three pentode stages and double triode input and output stages, is shielded and designed to have less than unity gain at the r.f. frequency obtained from oscillator 25, the high-frequency voltage on lead 40 being of small amplitude (see Fig. 1) since the latter is connected to the midpoint of winding 35.

Abstract: 644,721. Spray carburetters. ALLDAY, G. J. June 4, 1948, No 15193. [Class 7 (iii)] The supply of light or heavy fuel from float chambers 27, 26 to a nozzle 21 is controlled by a two-way spring-loaded valve 16 operated by an electro magnet 10 controlled by a switch actuated by a device 12 responsive to engine temperature. The valve 16 has valve faces 28, 29 co-operating with seats 30, 31. The device 12 is situated in the engine cooling system or an exhaust heated vaporizer, and energizes the electromagnet 10 when the engine is cold to move the valve 16 to the left, closing the heavy fuel port 23 and opening the light fuel port 22.

Title: Electroluminescent image converter
IPC: H05B33/22
Filed: 1956-05-18
Abstract: 794,232. Semi-conductor devices. STANDARD TELEPHONES & CABLES, Ltd. May 18, 1956 [May 20, 1955], No. 15567/56. Class 37. [Also in Group XL (a)] The radiation sensitive layer of an electroluminescent image converter comprises a substance with a high variation of the dielectric constant with temperature, preferably those in which the dielectric constant changes abruptly with temperature. The alkaline earth titanates, particularly of barium and strontium, and mixtures thereof, or mixtures with a metallic oxide, e.g. lead oxide, are suitable for the intensifying of infra-red images. The device may comprise a mica disc 1 carrying a transparent conductive layer 2; an electroluminescent layer 3, the radiation sensitive layer 4 and a conductive layer 5 permeable to the rays. Layers 3 and 4 may be combined in a single layer containing a mixture of the two substances (Fig. 2, not shown), and this layer may be of individual broken particles instead of uniform (Fig. 3, not shown), so as to cut down heat conduction across the cell. The layers may be spaced to reduce heat conduction. Soot, spongy platinum or glass powder may be added to increase radiation absorption and a separate heat or infra-red source may be included to preheat to the jumppoint of the dielectric constants of the materials. Preheating may be obtained by passing electric current through the conductive layers. There may be no support layer if the remaining layers have sufficient mechanical stability. The cell is mounted in a radiation protected evacuated container.

Title: Improvements in feed-water regulators for boilers or the like
IPC: F22D5/10
Filed: 1929-05-21
Abstract: 326,100. Cockburns, Ltd., and Mac- Nicoll, D. May 21, 1929. Valves controlled by pilot or relay valves.-A feed-water regulator for steam generators of the kind in which the feed valve is actuated by fluid pressure acting on a differential piston under the control of a float-actuated balanced auxiliary valve has at least one face of the piston acted upon continuously by a fluid having a constant pressure,. which may be higher or lower than the boiler pressure. In the form shown in Fig. 1, the auxiliary valve is formed as a shoulder on a tubular spindle 55 connected to a counter-balanced lever 51 provided with an adjustable fulcrum 52. The lever 51 is pivoted at 50 to a float 49 adapted to work in a chamber 48 connected to the boiler by upper and lower pipes 81, 83. The spindle 55 passes loosely through a cover 58 into a bore in the differential piston 59, whose its shoulder co-operates with a seat on the piston, relative movement being limited by wings 75 on the spindle working between shoulders in the bore. The annular space below the smaller piston is connected to a region of low pressure through passage 74 and port 73. The second fluid is admitted through a port 78 and acts on the lower face of the larger piston. Boiler pressure passes through the spindle 55 to balance the auxiliary valve and through the leakage space between the spindle and cover to depress the piston when the auxiliary valve is closed. The lower end of the piston is coupled by an articulated spindle 62 to the feed valve 61. In a modification, the valve is isolated from the boiler and the valve is actuated by the second pressure under the control of the auxiliary valve, which either controls the supply or the exhaust of the fluid to or from the larger surface of the larger piston, the constant pressure either acting on the annular surface of the larger piston or on the smaller piston. Specification 294,330 is referred to.

Title: Improvements in and relating to fuel admission systems of compression-ignition internal-combustion engines
IPC: F02B9/00
Filed: 1945-06-20
Abstract: 590,107. Supplying liquid fuel. PHILIPPOVIC, J. W. June 20, 1945, No. 15774. [Class 7 (iii)] In a compression-ignition engine having a small ante-chamber 12 communicating with the cylinder by a convergent-divergent passage 10, liquid fuel is admitted cyclically to an annular pocket 25, Fig. 3, bounded by sharp-edged orifices 20, 21, at the throat of the passage. Two hollow plugs 17, 18, fitting in a boss 15 in the cylinder head and having uniformly tapering passages curving inwards at their inner ends 20, 21, form the passage 10, and the chamber 12 is formed in a plug 28 of ceramic material. A fuel admission ring 24 forms the annular pocket 25 between the orifices 20, 21, to which fuel is admitted from an annular chamber 27 through radial grooves 26. Liquid fuel from a float chamber 40 flows to the chamber 27 past a needle valve 39, connected to the engine control, and a non-return valve 32, maintained closed by spring 35. A poppet valve 37 carried on the stem of the valve 32 closes if the pressure-drop across it exceeds a predetermined value. ' The plugs 17, 18, and 28 and the ring 24 are locked in the boss 15 by a screw plug 29. In operation, the pocket 25 is full of fuel at the beginning of the compression stroke and turbulence produced at the orifice 20 in the air forced through the passage 10 scours fuel from the lower part of pocket 25. After ignition in the chamber 12, turbulence produced in the reverse flow at the orifice 21 scours the remaining fuel from pocket 25, combustion of which occurs in the cylinder. The pocket 25 is refilled with fuel for the next cycle when the pressure in the throat drops to a value which allows the valve 32 to open. The orifice 21 may be omitted.
