Title: Improvements relating to apparatus for the regulation of the voltage across a load circuit supplied with direct current
IPC: H03K5/24
Filed: 1953-03-31
Abstract: 743,079. Automatic voltage and current control systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., WALKER, A. H. B., MARTIN, R. G., and KING, K. G. Dec. 30, 1953 [March 31, 1953], No. 8843/53. Class 38 (4). In an automatically controlled D.C. supply system in which the output voltage of a metal rectifier is maintained constant by a controlled saturable reactor until an upper load current limit is reached at which value the current is maintained constant, the change-over is effected by connecting the voltage control signal to the reactor via a first metal rectifier shunted by second and third metal rectifiers in series, and connecting the current control signal via a fourth metal rectifier connected to the midpoint of the second and third rectifiers. The voltage supplied to the D.C. load 10 by main rectifier 46 from A.C. mains 4, 5 is controlled by the saturable reactor 42 in accordance with a control signal applied to the valve 28 as disclosed in Specification 677,673. This signal consists of either part of the load voltage tapped off a potentiometer 13, or a voltage proportional to load current derived from current transformer 18 and rectifier 19. The voltage control signal is applied to the grid of valve 28 via metal rectifiers 25, 26, 27. The current control signal is applied via rectifiers 17, 26, so that when the load current exceeds a predetermined value rectifiers 17, 26 conduct, whilst rectifiers 25, 27 are blocked, and the system regulates for constant load current. Below this value, rectifiers 25, 26, 27 conduct and the system regulates for constant voltage. When two or more regulated rectifier units operate in parallel, hunting is probable under constant current conditions, and to minimize this, a tapped resistor is inserted between point 23 and the rectifier 17, the tapping being connected via a condenser to a bus-bar common to each unit, Fig. 4 (not shown).

Title: Light-filtering systems
IPC: G03B27/73
Filed: 1964-03-03
Abstract: 1,059,148. Filtering systems for lenses; light guides. WARSZAWSKIE ZAKLADY FOTOOPTYCZNE. March 3, 1964 [March 14, 1963], No.8918/64. Headings G2A, G2C and G2J. A lens system has a diaphragm stop located between two filters, each filter having a central colourless section and two differently coloured end sections, each coloured section being one of the three subtractive primaries. Fig. 1 shows the principle. The lens system comprises two lens elements s, between which is an apertured stop 7. On each side of stop 7 is a colour filter, slidable in the direction of the arrows. Each filter is in three sections: a colourless central section (e.g. 4a), and coloured end sections (4b, 4c), the colours being any two of the three subtractive primaries. The coloured sections 5b, 5c of the other filter are such that the filters have one colour in common. Fig. 2 (not shown), illustrates the arrangement as used in an enlarger or colour printer, making a copy of a negative (N) on a positive (P). If the three primary colours are A, B, and C, then by suitable positioning of the filters, any of A, B, C, alone, or any of the combinations A + B, B + C, or A + C may be selected. Fig. 4 (not shown), is a practical realization of the scheme of Fig. 1, having two lower lenses (1, 2) and a compound upper lens (3). The two filters (4) (5) are slidably mounted, with the stop 7 between them, and can be moved by a rack-and-gear arrangement operated by knobs (18) at either side of the apparatus, the knobs carrying scales (19). The scales are illuminated by a forked light guide (26), Figs. (not shown), 7 and 8, made of a plastics material of high transparency. This has a bevelled end (27) disposed in the path of light coming through the lens system, and the light is conveyed through the two limbs of the fork, each of which has a further bevelled end (28), to illuminate the scales (19). After the scales have been set, the light guide is swung out of the way to allow unobstructed use of the lens system.

Title: Improvements in the manufacture of ethylbenzene
IPC: C07C2/68
Filed: 1944-05-10
Abstract: Ethylbenzene is prepared by adding to benzene 2-5 per cent of its weight of anhydrous aluminium chloride and bringing ethylene into contact with the benzene at a temperature of 140-220 DEG  C. under a pressure sufficient to keep the benzene in the liquid phase.  In an example, benzene, dried by fractionation and aluminium chloride are introduced into a stainless steel autoclave and heated with stirring. Ethylene is then introduced, beneath the liquid surface, under pressure and the pressure maintained until about half the theoretical amount has reacted.  The mixture is then cooled when two layers form. The upper layer is removed and fractionally distilled, giving ethylbenzene, unreacted benzene and a small residue of higher ethylated benzenes.  The latter is added to the lower layer which contains the remaining higher ethylated benzenes and aluminium chloride.  Further benzene and aluminium chloride are then added to the autoclave and the process repeated.  An industrial gas containing ethylene, ethane, methane and air is employed in a further example as a starting material.  In the Provisional Specification it is stated that a little hydrogen chloride may be introduced with the ethylene, and that the reaction mixture may be removed to another vessel for separation into layers.  Specification 303,505, [Class 91], is referred to.

Abstract: 757,550. Liquid fuel burner. MAYER, W. March 26, 1954 [March 26, 1953], No. 8965/54. Class 75(1). A heating stove has a turbine driven by exhaust gases connected to a pump for supplying oil under pressure to a burner and has a combustion chamber arranged between the turbine and an air supply compressor producing a slight pressure in the combustion chamber whereby operation of the stove is automatically maintained. The hot gases from a combustion chamber c rotate a turbine wheel f mounted on a shaft d to drive a pump c which supplies fuel to burner nozzles h through preheating tubes g. A compressor rotor w driven by a turbine wheel mounted on a tube surrounding the shaft d compresses the incoming combustion air supplied to the chamber e. The pump c is mounted in the oil storage chamber b. The apparatus is started by rotating a crank k and gearing j to feed fuel to the burners g until the hot gases take over the drive, the crank h then being disconnected. In a modification, Fig. 4 (not shown), the incoming air is heated in a pre-heater by the exhaust gases and the oil storage tank is arranged at the side of, to be heated by, the combustion chamber.

Title: A system of access from a plurality of data-processing apparatus to an appliance
IPC: G06F13/16
Filed: 1970-02-26
Abstract: 1,249,617. Telephone metering systems. INTERNATIONAL STANDARD ELECTRIC CORP. 26 Feb., 1970 [28 Feb., 1969], No. 9270/70. Heading H4K. A number of processors transfer call charge data, one processor at a time, to a single slowspeed bulk tape store, an application for transfer being accepted so long as no other transfer is in process, transfer being effected character by character the tape store calling for a processor program interrupt each time it is ready to record another character. Each of eight processors, of which only processor 1 is shown in Figs 2a, 2b, has a corresponding bistable in an array 4, and has a pair of interrogation gates, such as 18, 30, in an array 3. If the magnetic or punched paper tape store 9 is idle no bistable in the array 4 is set and all the interrogation gates in the array 3 are open. The first processor to request data transfer does so by signalling on a lead 2 such as shown for processor 1. Since interrogation gate 18 is open lead 5 is active to set the processor's bistable in array 4 and lead 7 is active to instruct the processor that the tape store is idle. With a bistable set in array 4 all. but the corresponding ones of gates in a lock-out array 6 are blocked and this blocks all but the corresponding interrogation gates in array 3. To confirm its sole command of the tape store the processor signals over lead 8 to ensure that interrogation gate 30 is open and to receive notice back over lead 7. If two processors seized the arrangement simultaneously two bistables in array 4 would be set and neither would receive confirmation over gates 30 as all gates would be locked-out by array 6. Both processors would retire and reapply with, in all probability different delays. Once confirmed in sole command a processor sends the first character and takes up other program tasks. When the tape store is ready for another character it signals on lead 11 and over a gate 40, in an array 12 and held open by the processor's bistable in array 4, the processor receives a request for a program interrupt. The processor validates the request by a signal on lead 10 returned over gate 45 in array 12 and sends the next character. After sending the last character a clearing signal is applied to lead 15 to reset the processor's bistable in array 4 and unblock the interrogation gates.
