Abstract: 768,626. Oil gas. UNITED GAS IMPROVEMENT CO. April 25, 1955 [April 30, 1954], No. 11856/55. Class 55 (2). A cyclic process for producing an oil gas of high calorific value comprises, in one part of the cycle, passing through lines 10 and 11, or 19, a vaporized normally liquid petroleum hydrocarbon and steam into a hot zone 1 containing a catalyst 5 having a temperature gradient not greater than about 100‹ F. and consisting of nickel-containing refractory bodies having a mass between about 95-1000 lb. per 100 sq. ft. of surface and a nickel concentration, In the outer <SP>1</SP>/ 32  inch of surface,- of between 1.4 and 4 lb. per 100 sq. ft. of surface, at a rate to give a value between 2 and 6 for the ratio: then, before the temperature in the catalyst zone falls appreciably more than 100‹ F:, discontinuing the flow of hydrocarbon and steam and reheating the catalyst zone and regenerating the catalyst by burning off the carbon and sulphur deposited. During reheating of the catalyst fluid fuel and air are admitted through lines 7 and 8 to a combustion chamber 4 and the hot gases are passed through the zone 1 to leave through the stack valve 9. Carbon and sulphur are burnt off by admission of air, preferably before the reheating of the catalyst begins, and subsequently after reheating the catalyst is reduced back to the metal by admission of a reducing gas, e.g. producer gas, or the reduction may be effected in the initial stages of the gas-making period. Steam for the process when admitted at 19 is superheated by the chequerwork 17 and is employed at a rate between 0.8 and 3 lb. per pound of carbon in the petroleum hydrocarbon reactant. Air may also be admitted during the gas-making period and the temperature in the hot zone may be between 1400-1700‹ F. The temperature swing during the cycle is not more than 100‹ F. and the complete cycle lasts between 1.5-3 minutes, the gas-making period taking up 35-55 per cent of the cycle. The concentration of nickel in the catalyst is preferably between 2 and 3 lb. per 100 sq. ft. of surface and the ratio is preferably between 3 and 5. Specification 740,634 is referred to.

Title: Improvements in or relating to apparatus for indicating or selecting radio programmes and controlling radio receivers
IPC: G04C23/00
Filed: 1952-05-15
Abstract: 719,157. Distributing music &c. HOEPP, K. May 15, 1952, No. 12330/52. Class 40 (4). [Also in Group XL(c)] In an arrangement for indicating or selecting programmes from different transmitting stations, the time position of an impulse, sent by a control station, relative to a synchronizing impulse is used to indicate the type of programme, e.g. dance music or variety, and in the case of a station equipped with automatic'selection equipment to achieve the reception of a station transmitting the required type of programme. The programmes available are monitored sequentially in loudspeaker I, Fig. 1, and operation of the press button appropriate to the type of programme received from each, closes a corresponding pair of contacts Q. The contacts are scanned by distributor arm 19 and pulses indicative of closed contacts are transmitted in time-positions relative to the time of passing synchronizing contact 18. The simple indication receiver, Fig. 3, has a dial 26 marked in sectors according to type of programme, each sector being marked with all the available stations, and a rotating arm carrying a lamp 25 is rotated synchronously with arm 19 at the transmitter. Synchronizing position 24a is marked and incoming pulses light the lamp 25 to indicate the type of programme on each station. A combined 'indicator and selecting apparatus, Fig. 4, includes an electromagnet 31 at the end of the rotating arm to operate switch contacts' 32 in response to a received pulse. The number of contacts corresponds to the number of stations and the dial together with the synchronous motor can be turned by knob 35 so that the sector corresponding to the desired type of programme can be brought into correspondence with the switches 32. The closing of one switch 32 connects one of the condensers 33 across inductance 34 and prevents the closing of further contacts. Push button 36 releases the closed contacts and permits the setting of the contacts corresponding to the next station transmitting the desired type of programme. A fully automatic push-button selection apparatus is described with reference to Fig. 5 (not shown). Reference is also made to the use of the longer synchronizing impulses for controlling a clock.

Filed: 1972-03-16
Abstract: 1339105 Cathode-ray tube circuits INTERNATIONAL STANDARD ELECTRIC CORP 16 March 1972 [19 March 1971] 12348/72 Heading H4T In a cathode-ray tube raster distortion (pincushion) correction circuit the line frequency deflection waveform is modulated by a combined signal comprising a first component having a parabolic waveform and derived from the frame deflection signal and a second component comprising a D.C. voltage the magnitude of which is a function of the beam current of the cathode-ray tube. As shown (Fig. 2) the working winding of a transductor Td is connected across a portion of the primary winding W1 of the line output transformer and the control winding ST supplied with a parabolic waveform frame frequency signal via terminal 42 and transistor TR1 and with the D.C. voltage developed across resistor 26 in the EHT circuit 20 via conductor 24 and transistor TR2. The line deflection coils are thus supplied from generator 11 over conductor 13 with a deflection waveform that compensates for pincushion distortion arising from the geometry of the display tube and additionally compensates for "corner astigmatism" which is a function of the variation in EHT voltage caused by the varying loading of the line output circuit by the operation of the pincushion correction circuit.

An exit means (e.g. a slit) in tube 30 allows filtered liquid (flowing outwardly through the filter assembly) to pass from the tube 30 into an (e.g. pocket shaped) baffle means 90 which allows escape of liquid (e.g. through holes 100) below a normal fluid level. Aeration of liquid is thereby avoided. A by pass valve 104 may be fitted which opens under increased pressure drop to pass liquid directly from the inlet fitting 24 to the interior of tube 30. The assembly 20 may comprise two pairs of two axially abutting filter elements.

Filed: 1975-03-26
Abstract: 1496954 Valves BENNES MARREL 26 March 1975 [4 April 1974] 12550/75 Heading F2V In a distributor for supplying hydraulic pressure to one or more mine roof supports, a barrel 10 is rotatable about the axis 27 to connect a pressure supply inlet duct 5, 122 to one or more working lines 7, and an operating handle 41 is pivoted about pin 42 to open valve 32 to supply pressure to the line(s) 7 and to close valve 40 to cut-off communication of line(s) 7 with exhaust via annular chamber 19, space 14 and duct 8. The inlet duct 122 upstream of the valve 32 is always pressurized and the pressure acts on a piston 45 to bias the lever to cause the end 35 of a piston 34 to abut the ball 32. The diameter of the piston 34 is greater than that of the piston 45 so that if the handle is released when the valve 32 is open the pressure on the piston 34 will automatically move the lever, close valve 32 and open valve 40. The inlet duct 122 downstream of the valve 32 divides into two passages 24, 25 which open at a lower face 13 of the barrel at respective tubular shoes 28, that bear on the surface 12 of the body, into which four pairs of lines 7 open. The body is provided with twelve spaced notches 51 into which a catch 53 can pivot if the shoes are correctly positioned in line with a line 7 or completely closed by the surface 12. Either or both lines 7 of a pair can thus be pressurized. Since the space 14 is open to exhaust the lines 7 not aligned with a shoe 28 are depressurized.
