Patent GB-830789-A (GB)
Title: Improvements relating to the catalytic reforming of petroleum hydrocarbons
IPC: B01J23/04
Filed: 1956-12-07
Abstract: A catalyst for upgrading catalytic reformates (see Group IV (b)) comprises chromium oxide on alumina and a minor proportion compared with the chromium oxide of lanthanum or a lanthanon or a mixture of lanthanons which may be in combined form, and optionally an alkali metal preferably potassium or compound thereof.  The mixture of lanthanons referred to is a commercially available mixture containing (expressed as oxides) 24% lanthanum, 47% cerium, 19% neodymium, 6% praseodymium, 3% samarium and 1% gadolinium and ytterbium.  A preferred composition contains 5-25% chromium oxide, 0.1-5% lanthanum or lanthanons, calculated as oxide, and 0.1-5% alkali metal, calculated as oxide.  The catalysts are prepared conventionally by impregnation of alumina.  A catalytic reformate or portion thereof treated with the above catalyst at 450-580 DEG  C. and not more than 50 p.s.i.g. in the absence of added hydrogen is used as a component of motor fuels. If a part only, e.g. a lower boiling fraction or a raffinate from a solvent extraction process removing aromatics, is treated, the product may be blended with the untreated portion.  The proportions of blending may be adjusted to give adequate volatility and the octane number maintained by addition of T.E.L. It may also be blended with heavy cat. cracked gasoline or alkylate.  Specification 820,403 is referred to.ALSO:Catalytic reformates are further upgraded by contacting at least a portion at 450-580 DEG  C. and not more than 50 p.s.i.g. with a catalyst consisting essentially of chromium oxide on alumina with a minor proportion with respect to the chromium oxide of lanthanum, a lanthanon or a mixture of lanthanons (see Group III), there being no added hydrogen, extraneous or recycle.  The pressure may be subatmospheric but about atmospheric is preferred.  Space velocities of 0.1-1 vol./vol./hr. can be used. The feedstock is preferably a platinum reformate.  A lower-boiling fraction only may be treated a substantial proportion of which should boil below 100 DEG  C. or the reformate may be solvent extracted to remove aromatics and only the raffinate treated, the treated fraction may then be recombined with the untreated fraction.  The feed may also contain material boiling below the initial boilingpoint of the feed to the platinum reforming process, thereby increasing the volatility of the product; this may also be done by adjusting the proportions when blending treated and untreated portions of the reformate or the end boiling point of the lower-boiling fraction may be such as to exclude toluene-forming components.  The catalyst may contain 5-25% chromium oxide, 0.1-5% of lanthanum or lanthanom (as oxide) and preferably also contains 0.1-5% of an alkali metal (as oxide); it may be used in a fluidized moving or fixed bed. Specification 820,403 is referred to.

Title: Improvements in or relating to printing telegraphs
IPC: H04L17/00
Filed: 1928-12-19
Abstract: 326,805. Okamoto, Y. Dec. 19, 1928. Relay type-lever actions. - In a printing telegraph each key of the transmitter keyboard controls the emission of a combination of impulses and non-impulses which operates a corresponding type-lever at the receiver. The starting-break in the signalling- current releases a spring-pressed stop lever 60 from a stopping cam 62 and thus produces a synchronized single revolution of a type-lever operating cam 106, Fig. 4, and a multiple tripping member 53 having trippers 56 corresponding to the contacts of the transmitting commutator. An impulse causes a solenoid 50 to lift the tripping member so that the corresponding tripper engages a lever, which moves, through levers 76, 87 and an operating cam 80, the corresponding segmental selector bar 90 to one of its two positions. In the absence of an impulse the selector bar is moved to its other position. A pull lever 95 enters the set of notches 94 in the selector bars aligned as above, and a latch 98 on the pull lever is engaged by a lifting-plate operated from the cam 106 to print the appropriate character.

Patent GB-799750-A (GB)
Title: Method for making cellular materials
IPC: C08J9/06
Filed: 1956-12-10
Abstract: Cellular vinyl chloride resins are made by expanding a plastisol by reacting therein water and a borohydride of sodium, potassium, rubidium or caesium (whereby hydrogen is liberated), and heating the expanded plastisol to gel and fuse it.  The plastisol is a dispersion of a homopolymer of vinyl chloride, a copolymer of vinyl chloride (e.g. with vinylidene chloride, vinyl acetate or ethyl maleate) or a mixture of homopolymer and copolymer (e.g. a mixture of polyvinyl chloride and a vinyl chloride/vinylidene chloride copolymer), dispersed in a liquid plasticizer (e.g. dioctyl phthalate, diisoctyl phthalate, isooctyl isodecyl phthalate, octyl butyl phthalate, butyl decyl phthalate, didecyl phthalate, dioctyl adipate, tricresyl phosphate, trioctyl phosphate or acetyl tributyl citrate) and if desired additives such as stabilizers, fillers or colourants. Reaction between the borohydride and water is effected by lowering the pH and/or by heating.  The borohydride may be added to the plastisol as such or in the form of an aqueous solution or dispersed in a plasticizer. Alternatively, separate plastisol components may be formed one containing the borohydride and the other the water and the two plastisols mixed in a mould.

Abstract: 307,741. Dunham Co., Ltd., C. A., (Assignees of Dunham, C. A.). March 12, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Heating buildings. -In a steam-heating system for buildings, the steam in the radiators is maintained at sub-atmospheric pressures by an exhauster, the quantity of steam supplied is controlled by a thermostat or otherwise, and a valve for discharging condensate is operated by a capsule containing a liquid adapted to exert pressures in excess of the vapour pressure of steam at the same temperature by a substantially constant amount. A boiler 10 supplies steam through pipes 13, 16 to a radiator 15 which discharges through valve 39 and pipes 17, 14 to the boiler. A drip pipe 19 is connected from the steam pipe 13 to a point between check valve 18 and the boiler. The pipe 14 is provided with an air eliminator 20. A vacuum pump 24 is connected by suction pipe 25 to the piping 22 above the level of the horizontal return pipe 14<1>. The pump is controlled by a device 27 connected by pipes 28, 29 to the low and high pressure sides of the system, so as to maintain a sufficient pressure difference to ensure the removal of water of condensation and air. The quantity of steam supplied may be controlled by a reducing valve on the pipe 13, or by means of a thermostat 32 controlling the furnace dampers 11, 12. The radiator inlet valve 36 is associated with an apertured plate to restrict the inflow of steam when the heating is started, but the aperture is sufficiently large to have no influence in normal operation. The steam trap 39 comprises a flexible capsule 42 carrying a valve 44 controlling the outlet pipe 17. The capsule contains a volatile liquid having a vapour pressure exceeding by a constant amount over a range of temperature, the vapour pressure of steam.

Filed: 1969-07-29
Abstract: 1277104 Cleaning brushes JOHNSON FAST PRINT MACHINE CORP 29 July 1969 38099/69 Heading A4F A method of washing and thereafter quickly drying a rotatably mounted brush comprises directing jets of washing liquid against the periphery of the brush at constant high-pressure simultaneously to rotate the brush at high speed and to wash it, and cutting off the supply of washing liquid abruptly without first substantially reducing its pressure, thereby leaving the brush rotating at high speed to dry. Apparatus for performing the method comprises a hydraulic piston 22 arranged to be reciprocated in a cylinder 10 to drive, via coupled piston-rods 23, 43, a piston 42 in a cylinder 12 having a single inlet and outlet port 52. In one direction of movement of the piston 42 washing liquid is drawn from a reservoir 54 into the cylinder 12, and in the opposite direction of piston movement washing liquid is discharged via the opening 52 and nozzles 68 on a header 56 on to the periphery, of a brush 72. mounted for rotation in a base 76. When the piston 42 reaches the end of its forward stroke the discharge ceases abruptly and the brush 72 continues to rotate to dry. The length of the piston stroke is variable by adjustment of a switch 50 relatively to an actuator 46 carried by the coupling 44 between the piston-rods 23, 43. The actuator 46 opens the switch 50 on striking it thereby closing solenoid valves 30, 40 and opening solenoid valves 32, 38 to reverse the movement of the piston 22.

Filed: 1957-12-11
Abstract: 910,781. Automatic phase control systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 11, 1958 [Dec. 11, 1957], No. 38461/57. Drawings to Specification. Class 40 (5). [Also in Group XL (b)] The phase of the line and frame synchronizing pulse generators at remote television camera stations is synchronized with a master oscillator at a central station, to facilitate switching over, by phase comparison of sync signals from the remote stations with oscillations derived from the master oscillator and the transmission from the central to the remote stations, in a speech communication channel, e.g. a telephone line, of control signals correcting phase errors if any at the remote line and frame generators. The control signals may be a frequency-modulated voice frequency carrier and an on-off amplitude modulated carrier of frequency, e.g. 300 c/s., both transmitted by ordinary telephone line to the remote station for respective control (1) of the line frequency by controlling through a reactance valve the remote slave oscillator deriving the line frequency by frequency division, and (2) of the frame frequency by varying the division ratio of a frequency divider operated by the slave oscillator. A plurality of remote stations may be controlled from the central station and remote stations may be synchronized in sequence in a similar way from a preceding remote station. Automatic switching of a remote station to crystal or local mains frequency control on failure of the central control may be arranged. The remote station frequency discriminator may be a counter type as described in Specification 596,459. According to the Provisional Specification the synchronizing control signal transmitted to the remote station may be a pulse frequency, pulse width or pulse time modulated signal. Moreover the frequency discriminator may be replaced by a phase discriminator comparing the phase of the control signal with a subharmonic of the slave oscillator within the telephone band. The line control signal alternatively may be produced by oppositely amplitude modulating two tones of frequency e.g. 3400 c/s. and 3200 c/s., or of equal frequency but different phases, and using the difference or ratio of the amplitudes at the remote station to counteract changes in loop gain control.
