Title: Method for cracking liquid hydrocarbons
Inventor: ISHIBASHI WATARU
IPC: B01J19/08
Filed: 1965-05-31
Abstract: <PICT:1103661/C4-C5/1> Large quantities of acetylene and smaller quantities of lower olefins are produced by cracking a liquid hydrocarbon in the liquid phase by means of spark discharge which is created by dispersing carbon powder in the hydrocarbon and immersing therein two electrodes to which a pulsating current is applied, spark discharge taking place due to random contact between the carbon particles.  The process may take place at relatively low temperatures, e.g. 20-60 DEG  C.  In Fig. 2, a cracking vessel 8 is provided with carbon electrodes 11 and 12 connected to a pulsating current source 20.  Liquid hydrocarbon, e.g. a heavy oil containing dispersed carbon powder, enters from line 13 via perforated plate 10, and the current causes fluidization of the carbon particles. Cracked gases are evolved and leave vessel 8 by line 17.  An overflow 16 is provided for the excess liquid hydrocarbon which passes through filter 15 and is returned by pump 14 to the bottom of vessel 8. Make-up liquid hydrocarbon is provided via inlet 21 to filter 15, and since the cracking process itself produces carbon no additional carbon need be added once the reaction has started.  If too much carbon accumulates it may be removed by a carbon-eliminator (not shown) within filter 15.

Abstract: 188,434. Cambridge & Paul Instrument Co., Ltd., Orchard, J. L., and Stallan, W. J. Sept. 2, 1921. Indicating.-A sensitive adjustment for galvanometers and other physical instruments, electric resistances, &c., is provided by the rotation of a wire flexed at one end which exerts a pressure upon a second movable member and produces movement thereof. The device is shown as applied to the controlling- spring of a moving-coil electric instrument. A bridge-piece B is supported across the magnet poles A, A and carries a roundedged disc C adapted to rotate in a bearing D. The disc carries an arm E to which is attached one end of the hair spring which controls the moving coil and its index linger. A vertical rotatable member F is journaled in the bridge-piece B, to which it is held in frictional contact by a spring- washer G, and is disposed so that its axis produced intersects the plane or the disc C. A resilient wire H is rigidly attached at its upper end to the upper portion of the member F, the lower portion of which is bored to allow of flexure of the lower end J of the wire where it exerts pressure upon the edge of the disc. Rotation of the member F produces a corresponding rotation of the disc, and the degree of sensibility can be varied by varying the relative diameters of the disc and flexed wire. In a modification, the disc C is replaced by a sliding member.

Title: Improvements in the manufacture of cloth or garments
IPC: D06M11/05
Filed: 1944-11-24
Abstract: A fabric, which is made from a yarn formed by spinning a mixture of wool and fur fibres, is treated with hot water or a hot aqueous liquid and thereafter the fabric while still hot is contacted with cold water and rinsed.  Preferably the hot aqueous liquid is a solution of soap, e.g of a mixture of alkali soap and oil soap.  A detergent such as a sulphated or sulphonated glyceride may be present.  The washing treatment may be carried out at 120 DEG -130 DEG  F. for about 20 minutes.  After removal of water and soil, fresh water may be added together with soda ash and washing may be continued at 115 DEG -120 DEG  F.  A further quantity of water at the same temperature together with mineral oil and a germicide may be added.  The liquid is drained off, and while the fabric is still hot, it is rinsed in cold water.  The water is extracted until the fabric is damp and the fabric is then dried in a heated tumbler.  The fur fibres may be of mink, racoon, beaver, muscrat, or vicuna.  The mixed wool and fur yarn may contain 20-40 per cent of fur.  Long or short wool fibres may be used. Knitted or woven fabrics may be treated.  If desired the process may be carried out on garments such as sweaters. Ammonia, or cresols may be used as the germicidal substance.  The treatment removes harshness of feel and gives a soft handle.  Rinsing the hot fabric in cold water causes the wool fibres to contract and bind the fur fibres firmly.  The scouring treatment removes grease, fats, and odours.  The treatment brings the fur fibres to the surface of the yarn and causes them to close the pores in the fabric.  This effect is enhanced by the tumbling operation.

Abstract: 836,580. Elastic-fluid turbines. PLESSEY CO. Ltd. Aug. 15, 1956 [Aug. 16, 1955], No. 23551/55. Class 110 (3). [Also in Group XXIX] In a starter turbine for operation by air or gas and adapted to develop maximum power at a relatively low fraction of the uncoupling speed, the mass flow is reduced progressively over a major portion of the starting cycle by means of a speed-responsive device. An engine starter turbine a is prevented from overspeeding by the use of pivotally mounted nozzle blades e which are turned towards the tangential direction by a toothed control ring f which is turned, through a pinion g and a lever h, by a piston i. The supply of motive fluid, such as compressed air, from the turbine inlet d to the piston i is controlled by a valve j operated by a centrifugal governor k. Alternatively, overspeeding may be prevented by varying the number of nozzles in use or varying the degree of masking of a fixed number of nozzles, or by varying a restriction upstream of the nozzles.

Title: Improvements in or relating to sine-cosine magslip resolver arrangements
Inventor: STARKS-FIELD ALFRED BENJAMIN
IPC: G01S7/12
Filed: 1955-08-17
Abstract: 800,781. Cathode-ray tube circuits; sawtooth generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. May 22, 1956 [Aug. 17, 1955], No. 23693/55. Classes 40 (6) and 40(7). Relates to a magslip resolver circuit for resolving an input timebase into sine and cosine components for application to the X and Y deflection members of a radar P.P.I. cathoderay tube display in which the input waveform is applied to the input coil 3 of the resolver through an amplifier 12, a feedback voltage produced by a winding 4 tightly coupled to the input winding 3 being applied to the input of amplifier 12 to linearize the waveform. According to the present invention the linearity is further improved by generating a further feedback voltage proportional to the difference between first and second voltages proportional respectively to the rate of change of the magnetising force in the resolver and the rate of change of the flux density in the resolver. The invention is described as applied to an arrangement in which the input coil is a stator coil, the sine and cosine outputs being derived from crossed rotor coils 1 and 2. As shown, the first voltage is produced by connecting a resistor 13 in series with the input coil 3 and applying the voltage across said resistor to the grid of a valve 15 through a differentiating circuit comprising capacitor 14 and the input impedance of valve 15. The second voltage is applied to the grid of a valve 16 and is derived from an adjustable tapping on a resistor 17<1> connected across the feedback coil 4. Valves 15 and 16 are connected as a differential amplifier and the difference output from the anode of valve 15 is applied through a cathode follower 17 and adjustable resistor 18 to the grid of the amplifier 12; a further output from the cathode follower 17 is applied as negative feedback to the input of valve 15. The linearity of the timebase waveform can be controlled by adjustment of resistor 18 and the tapping on resistor 17<1>. Any undesired quadrature field in the resolver is cancelled by a correction circuit comprising a high-gain amplifier 9 feeding a main quadrature stator winding 5 and fed from a feedback quadrature stator winding 6. This circuit operates in a similar manner to amplifier 12 but differs therefrom in that its input terminal is earthed.

Abstract: 1311107 Gas chromatography, adsorptive separation of gases COMMISSARIAT A L'ENERGIE ATOMIQUE 18 May 1970 [22 May 1969] 23886/70 Headings B1L and BIX A continuous adsorptive separation of gases involves the use of at least four packed columns arranged in a circulatory loop, each column performing successively, as a result of a cyclic changeover, the function of a stripping column 27, an enriching column 28, a column 29 which collects a top gas enriched in one of the most strongly adsorbed components, and a column 30 for retaining the tail gas which is enriched in one of the least strongly adsorbed components. As shown valved lines 40, 51, 48, 45, 55, 59, 65 and 69 are open as a gas mixture is fed in via line 48 to enriching column 28. A fraction of the gas leaving this column is extracted through line 65 and passed via line 69, whilst the other fraction, which in the case of a deuterium-tritium separation is enriched in tritium is extracted through line 45. Simultaneously gas retained by column 30, which is a mixture depleted in tritium, is extracted via line 55 and fed back via line 59 whence the tritium depleted fraction is taken off via line 51 whilst the remainder passes on to column 27. Desorption of the columns may be carried out by pumping and/or heating by means of a jacket or by using an external heater through which an initial desorbed fraction is recirculated to desorb the remainder. The desorption results in a pressure rise which facilitates gas flow. Similarly column 29 is cooled whilst absorbing by passing the gas extracted through line 65 through an external cooler and recirculating. This results in a pressure drop which facilitates gas flow from column 28. The columns may be packed with an inert granular material which retains palladium metal for the dissolution of hydrogen, or with silica gel, activated charcoal or alumina or a molecular sieve, e.g. type 13X. The adsorbent may be deposited with an exchange inducing catalyst, e.g. nickel, platinum or palladium. The apparatus is particularly applicable to the separation of isotopes of, e.g. hydrogen, oxygen, boron, carbon, uranium or the rare gases or in the exchanges involved in the production of heavy water.

Abstract: 719,084. Bichromated resists. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Oct. 14, 1952 [Oct. 15, 1951], No. 23947/51. Class 98(2) An electro-plating stencil resist is prepared from a bichromated glue mixture on a metallic support by exposing it, through a negative pattern, to light of selected wavelengths not readily absorbed by the bichromated glue (e.g. wave-lengths greater than 400 millimicroms), and removal of the unexposed portions by controlled washing alternately with, water and then with a liquid capable of abstracting water, such as an aliphatic alcohol (e.g, ethanol) or a simple ketone. Light of the correct wavelengths may be obtained by passing the light from a mercury vapour lamp through a filter which absorbs light of wavelengths shorter than 400 millimicons. A suitable filter is a 1 per cent solution of sodium nitrite, about 1 cm thick. The bichromated glue mixture preferably contains less than 3 per cent by weight of bichromate, and it is preferred to harden the stencil after controlled washing, with formaldehyde and ethyl alcohol, followed by soaking in bichromate solution, washing again with ethyl alcohol and baking in the usual way. The stencil is then used for electroplating.
