Title: Apparatus for studying the deviations of voltage in electrical networks
Inventor: GAUSSENS PIERRE PAUL DANIEL
IPC: G01R1/30
Filed: 1960-03-25
Abstract: 898,511. Electric selective signalling systems. ELECTRICITE DE FRANCE. March 25, 1960, No. 10683/60. Class 40 (1). [Also in Group XXXVI] In a system for monitoring the deviations of a supply voltage V from its nominal value Vo means are provided for periodically sampling the supply voltage V and for producing a quantitised difference D = V - Vo, and means are provided for summing successive values of D obtained by repeated samplings-to give an approximation to the average or mean deviation of the supply voltage V from its nominal value- and also to sum successive values of D<SP>2</SP>-to give an approximation to the mean square deviation. The summation of D<SP>2</SP> is effected in two stages performed concurrently: first the integral part q of D<SP>2</SP>/M, where M is a scale factor so chosen that the maximum value of D<SP>2</SP>/M does not exceed 50 say, is summed and secondly the difference E = D<SP>2</SP>- Mq is summed, and then the sum of M times the first sum plus the second sum gives the precise value of #D<SP>2</SP>, that is M#q + #E = #D<SP>2</SP>. (Since q is the integral part of D<SP>2</SP>/M, #q is an approximation to #D<SP>2</SP>/M. Also E = D<SP>2</SP>  -  Mq is M times the fractional part of D<SP>2</SP>/M.) As described the supply voltage is applied to a voltmeter 1, Fig. 1,so arranged that when the supply voltage V equals the nominal voltage Vo the meter pointer assumes a central position. If the supply voltage deviates from its nominal value the pointer moves to the left or right. The meter also includes an arcuate array of contacts 3 and when it is desired to sample the supply voltage the pointer is depressed down on to these contacts to thereby mark one of the contacts to indicate the deviation D = V - Vo of the supply voltage from its nominal value. The contacts of the voltmeter are connected to three banks 4, 5, 6 of a rotary switch, the connections being such that if say contact r of the voltmeter is marked by the pointer then the wiper of bank 4 will have r contacts still to pass over when it reaches the marked contact, the wiper of bank 5 will have [r<SP>2</SP>/M] still to pass over, and the wiper of bank 6 will have r<SP>2</SP> - M [r<SP>2</SP>/M] contacts still to pass over. These switch banks control relays 7, 8, 9, which allow pulses to pass to counters 11<SP>1</SP>, 11<SP>11</SP>, 12 and 13 from an interrupter 10. Thus, at each sampling of the supply voltage the voltmeter pointer is depressed, the rotary switch makes one revolution and the required numbers are entered into the counters. Counters 11<SP>1</SP> and 11<SP>11</SP> count positive and negative deviations separately. A circuit (Fig. 2, not shown) is described for sampling the individual phases of a multi-phase supply system.

Title: Improvements relating to vertical retorts for the carbonisation of coal and the like
IPC: C10B1/04
Filed: 1954-04-14
Abstract: 768,694. Discharging vertical retorts. WEST'S GAS IMPROVEMENT CO., Ltd., WEST, SIR F. J., and WEST, E. June 22, 1955 [April 14, 1954.],No. 10962/54. Class 51 (2). In a vertical retort in which a carrier gas, e.g. water gas, and steam are admitted into the coke chamber and the retort is closed by interconnected inner and outer doors as disclosed in Specification 710,526, the inner and outer doors are interlocked with the carrier gas and steam control valves so that, before the doors can be opened, the carrier gas valve is closed and the steam valve opened, and that the doors are closed before the carrier gas valve can be opened and the steam supply cut off. The inner door a is carried by a pivoted shaft c having a crank arm d at each end, and the outer, sealing door f has hangers h pivotally attached to link arms i which rotate about a shaft and which carry the ends of a shaft k to which attached links m themselves pivotally attached to the said crank arms d. The shaft j has attached to one end a cam plate o which is formed with a two-part slot in which one arcuate part p is coaxial with the shaft j and the other arcuate part q is coaxial with a fixed pivot r about which an operating lever s turns. In the position shown, the lever s is holding the carrier gas valve 16 open through a link 12 and a crank arm 15, and the steam valve 14 closed through a link 13. The lever s carries a roller t engaging the cam slot and a hand wheel u on the shaft j operates the doors. In operation, the lever s is depressed closing the carrier gas valve 16, opening the steam valve 14, and moving the roller t to the junction of the cam slot parts p and q. A pivoted catch v is withdrawn from a bracket on the hanger h and the handwheel turned in a clockwise direction to lower the sealing door f through the link arm i and to lower the inner door a by turning the crank arm d through the links m. The lever s is locked by the positioning of the roller t at the end of the cam slot part p. Anticlockwise movement of the handwheel u closes the doors while the roller t moves along the cam slot part p and then lifting the lever s opens the carrier gas valve 16, closes the steam valve 14, and moves the roller t along the cam slot 9, the handwheel being locked by the catch v against clockwise movement. The carrier gas and the steam have a cooling effect on the coke in the lower part of the retort. Specification 745,319 also is referred to.

Title: Process and apparatus for the production of hydrocarbons of low boiling point from carbonaceous materials
IPC: C10G1/00
Filed: 1930-04-08
Abstract: The gaseous mass obtained in the production of low-boiling hydrocarbons from the carbonization of solid or liquid carbonaceous materials is hydrogenated as one stage of a number of treatments of the gaseous mass.  The mass is first purified from solid impurities and deleterious substances such as sulphurous, arsenical and other compounds, and reduced over finely divided metals, before undergoing hydrogenation.  In the latter treatment the gases, at a temperature of 180-250 DEG  C., pass through tubes filled with wire coils of metals or alloys such as iron, nickel, cobalt, vanadium.  The metals or alloys are treated to develop their catalytic action by means of the process described in Specification 350,451.

IPC: G11C8/00
Filed: 1957-04-05
Abstract: 864,119. Digital data storage-apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Feb. 26, 1958 [April 5, 1957], No. 11180/57. Class 106 (1). According to the Specification the remnant polarization of a slab of ferro-electric material can be significantly changed by.subjecting the material simultaneously to an electric field and a mechanical stress, whereas either the electric field or the mechanical stress by itself cause only an insignificant change in polarization. Two embodiments for storing binary data using the principle are described. In the first, Fig. 2, a ferro-electric slab 1 has a mechanical stress wave produced in it by a potential applied to an electrode pair 2, 3 (using the piezo-electric effect). This wave travels along the slab, being absorbed at the ends by two pads 4, and stresses in succession five notional storage cells T1, T2 ... T5, between an electrode pair 2, 5. Thus, in accordance with the above principle, data is entered into a selected cell by applying a potential across the electrode pair 2, 5 at the time when the stress wave reaches the selected cell(s). Further data can be stored in further cells in a similar manner between electrode pairs 2, 6 and 2, 7, and it is suggested that a " one " be entered in every cell between, for example, the 2, 7 electrode pair, so that during read out, which is non-destructive and which is effected merely by sending a stress wave through the slab, the pulses read from the electrode pair 2, 7 can be used as clock pulses. In the second embodiment, Fig. 3, the electric fields applied to selected cells at selected times are produced by two sets of electrodes 13a to 13d and 14a to 14c on a half select basis, and the mechanical stress wave is produced by a coil 11 co-operating with some magneto-strictive material 10.

IPC: G02B5/20
Filed: 1956-04-13
Abstract: 816,298. Ornamenting. RANK CINTEL Ltd. April 12, 1957 [April 13, 1956], No. 11323/56. Class 93 [Also in Group XX] A method of manufacturing a multielement light screen comprises superimposing two sheets of similar material, but differing in optical properties, subjecting the sheets to the action of a piercing press consisting of a punch and die so dimensioned that an element removed from the sheet which the punch first encounters is transferred to the aperture formed in the sheet remote from the punch and treating the sheet with a volatile solvent for the material so as to yield a composite sheet. The operation may be repeated to produce a composite sheet having three or more sets of areas of differing optical properties. The areas may be transparent to different colours and arranged contiguous to each other or may be transparent to one or more different colours dispensed in a predetermined pattern over an opaque screen; or the areas may differ in other optical properties such as density or direction of polarization. In an illustrated embodiment, Fig. 1 shows a punch 1 and cooperating die 2 between which are placed two sheets 3, 4 of similar but differently coloured translucent material; Fig. 2 shows the result of the piercing operation wherein punch 1 has moved downwards to remove a section 5 of material from sheet 3 and drive it into the hole in sheet 4 left by the simultaneous removal of section 6 which is thrust into the cavity of die 2; and Fig. 5 shows a three colour filter comprising a sheet 4 of green material having areas 5 of red material and areas 7 of blue material inserted in it by the method of the invention. The composite sheet formed as in Fig. 2 is treated with a volatile solvent which will penetrate the interstices between sheet 4 and element 5 and weld the two together before evaporation. Screens luminescing in different colours in response to incident radiation or electron bombardment may be produced by coating upon or incorporating in the surface or body of each of the sheets from which a composite screen is to be formed, an appropriate phosphor. The sheets themselves may then be coloured as necessary.

Abstract: 1,157,064. Hydraulic brake systems. HYDROEASE CORP. 8 March, 1968 No. 11428/68. Heading F2F. A reservoir 26, master cylinder 34 and a pressure booster cylinder 46 are all incorporated within a single cast metal housing 20 with the reservoir above the master cylinder and the booster cylinder below the master cylinder. In the arrangement shown in Fig. 2, when the brake pedal is actuated, brake fluid flows from the master cylinder 34 through channel 134 to the pressure booster cylinder 46. Initially, ball valve 110 is open to allow the brake fluid to flow through the interiors of pistons 70 and 88 and port 136 to the brake system. When the pressure of the brake fluid has increased to a level sufficient to overcome spring 120, both pistons are displaced to the right (as shown) and ball valve 110 then closes whereupon, due to the different effective areas of the different ends of the piston, the pressure in the right hand end of cylinder 46 is increased. Outer piston 70 then retracts providing additional pressure amplification. A bleed valve 140 is provided for the booster cylinder. For dual circuit brake systems, a single cast metal housing may contain two master cylinders having respective reservoirs and one (e.g. for the front brakes) or both master cylinders may be connected to a booster cylinder.
