Patent GB-584658-A (GB)
Title: Improved transparent sheets
Filed: 1945-01-19
Abstract: Transparent polystyrene sheets are produced by heating a composition comprising styrene in admixture with from 1-10 per cent by weight of the styrene of a compound having two methacrylyl groups per molecule and from 0.01 to 1 per cent of a peroxy compound in a cell formed of two sheets of a material inert to said composition, said sheets being held in spaced relationship by flexible gaskets and having their edges sealed by means of a flexible material, and thereafter placing the cell in an inert liquid bath at a temperature below the final temperature reached by the composition during said heating, but not more than 20 DEG  C. below said temperature.  It is preferred to use between 2 and 6 per cent of the compound containing two methacrylyl groups and the preferred compound is methacrylic anhydride although methylene-, ethylene- and ethylidenedimethacrylates are also specified. Benzoyl peroxide (0.05 to 0.5 per cent) is the preferred catalyst; others specified are dialkyl peroxides such as diethyl peroxide and diacyl peroxides such as acetyl and lauroyl peroxide. When glass is used as the inert material in the cell wall, the adhesion of the polystyrene to the glass is reduced by use of small quantities of a styrene soluble dispersant such as the sodium salt of sulphonated octyl ester of succinic acid.  In an example, the composition comprises styrene, methacrylic anhydride, benzoyl peroxide and the sodium salt of sulphonated octyl ester of succinic acid, the cell walls are of glass clamped together by G-clamps, the flexible material is polyvinyl alcohol, and the inert liquid is water.  The sheets may be used as glass substitutes in instrument panels, as shatter-proof windows in airplane enclosures and for the production of lenses.

Patent GB-574659-A (GB)
Title: Improvements relating to the production of micro-porous material
IPC: H01M50/414
Filed: 1944-02-02
Abstract: In the manufacture of microporous rubber for battery separators and the like by the incorporation and subsequent removal of fine particles, a rubber solvent which acts as a plasticiser is added to the dough to facilitate manipulation, particularly extrusion, the solvent being removed prior to vulcanization and washing out of the fine particles.  Suitable solvents are xylene, coal tar naphtha, higher ketones such as cyclohexanone.  Starch is a suitable pore-producing agent.  According to an example, 23 lbs. of natural rubber are mixed with 100 lbs. of maize starch, 6.3 lbs. of sulphur, 0.4 lbs. of diphenylguanidine, and 0.5 lb. of zinc oxide.  The mix is transferred to an internal mixer, and 30 lbs. of methyl cyclohexanone is added at 60 DEG  C.  The dough is extruded on to a belt conveyer which transfers it to a drying tunnel heated to 80 degrees to remove solvent.  The sheet is vulcanized as such, or cut up and interleaved with paper.  After vulcanization, the material is treated for 1 hour with 1 per cent sodium hydroxide solution and for 30 minutes in boiling wash water.  It is finally treated with a wetting-out agent. Reclaim or synthetic rubber may replace the natural rubber, wholly or in part.  Carbon, sawdust, lignin may be included in the mix. Specification 530,721 is referred to.

Title: Improvements relating to autographic recorders for compression tests on soils
IPC: G01N33/24
Filed: 1963-01-16
Abstract: 1,000,089. Testing soil. E. W. PARKER. Jan.16, 1964 [Jan.16,1963], No. 1940/63. Heading G1S. An autographic recorder for conducting triaxial compression tests on soil includes bellows adapted to provide a displacement movement commensurate with a load applied to a soil sample 1 in a test cell, the bellows displacement being transmitted to stress/strain recording mechanism. The soil sample 1 contained in a rubber membrane 3, immersed in water, is compressed by a screw-jack 6 against a movable plunger 7 to move a pivoted block 16 and interconnected bellows 17,18. Stress applied to the soil causes through bellows 17,18, a plunger 23 to rise and rotate the spindle 12 of a chart 11 through ratchet means 24, 25. Simultaneously, a pointer 13 is moved across the chart 11. Water expressed from the sample may flow away through a tube 30 into a pot 31 containing mercury, and its volume may be determined by measuring the overflow of mercury along a further tube 32. Electrical contacts closed by the mercury cause movement of the pea 39 across chart 12.
Patent GB-413704-A (GB)
Title: Improvements in and relating to systems of electric motor control
IPC: H02P5/50
Filed: 1933-01-20
Abstract: 413,704. Maintaining proportional speeds of motors. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London, POOL, W. J., Barby Lane, Hillmorton, and FOX, K. M., Southfield Road, both in Rugby. Jan. 20, 1933, No. 1945. [Class 38 (iii).] In a system wherein a number of motors are automatically controlled as to speed in dependence on the speed of a master motor, the speed regulating devices of each controlled motor are limited as to their rate of operation, during the starting of the controlled motor, by a master control device which becomes ineffective when the controlled motor reaches normal speed. The invention is described in relation to a system according to Specification 205,215, [Class 38 (iii)], wherein a shaft 6 moves to adjust the bushes of one A.C. commutator motor in accordance with speed variations of the motor which are detected by the movement of an electromagnetic field in a member 2 driven by the motor 1, the field being excited by a three phase generator driven by the master motor. The movements of the spindle 6 are conveyed through a countershaft 7 and chain to a spindle 10 of the brush shifting device A sleeve 19 loose on the countershaft 7 is coupled by worm gearing to a pilot motor 17, which is controlled by reversing contactors and a hunting switch 23 forming part of a master control system adapted to start all the mc tors and to run them at " creep " and " full " speeds. A slot in the worm gear 19 is engaged by a pin 20 driven by the countershaft 7 so that during starting the rate of movement of the brush shifting device is limited according to the speed of the pilot motor, but when normal speed is reached the sleeve 16 over-runs the countershaft 7 and the hunting switch then operates upon the pilot motor circuit to prevent the ends of the slot from engaging the pin 20. To ensure the production of adequate starting torque in the motor 1 when the master controller is set for the "creep" speed, in which the pilot motor and speed regulating devices are not normally energized, a centrifugal switch 12 driven by the motor 1 remains closed at low speeds and co-operates with an interlock contact operated by the brush shifting gear and time delay means to energize the pilot motor and speed regulating means to shift the brushes and so increase the starting torque. The pilot motor is caused to return the brush gear to normal starting position when the controlled motor is stopped and when the centrifugal switch 12 opens under " creep " conditions. The control arrangements are fully described in the Specification.

Title: Improvements in or relating to Percussion Fuzes for Projectiles.
IPC: F42C15/22
Filed: 1917-02-10
Abstract: 126,684. Rudge - Whitworth, Ltd., Pugh, J. V., and Pountney, F. Feb. 10, 1917. Projectile fuses.-Relates to percussion fuses of the kind in which the movement of a centrifugal locking-bolt out of engagement with an inertia pellet is retarded during the period of acceleration of the projectile, and consists in providing a frictional or like obstruction in the path of the bolt, the contour and arrangement of the parts being such as to result in an intermittent or escapement motion. In the fuse shown in Figs. 1 and 2, a centrifugal bolt g, which normally locks an inertia pellet c<4>, has lateral teeth g<8> adapted to coact with teeth v<6> at the sides of a slot in a rotatably-mounted washer v<3>. This washer is normally locked by an inertia detent p', but on discharge of the projectile, it is free to oscillate as the bolt g moves radially outwards. The escapement action as the teeth g<8> slide over the teeth v<6> effects the required retardation of the bolt. In a modification, the bolt has a series of alternatelyspaced teeth, coacting with a pivoted anchor escapement member. The arrangement may be such that the inertia pellet itself receives an intermittent rotational movement. Specification 126,387 is referred to.

Filed: 1976-01-16
Abstract: 1529223 Testing visco-elastic materials RUBBER & PLASTICS RESEARCH ASSOCIATION 16 Jan 1976 [17 Jan 1975] 2057/75 Headings G1N and G1S To test a visco-elastic material such as an unvulcanized rubber, a sample of the material is subjected to a predetermined pre-compression and subsequently to an additional test compression, and the load relaxation in the sample is monitored. As shown the sample is compressed in a chamber 18 between two plates 20, 38 which may be heated by coils 24, 44. Pre-compression and additional test compression are applied by pneumatic or hydraulic rams 70, 72 and 26, 28 respectively, the load in the sample being monitored by a pressure transducer 42. Solenoid valves 98, 100 for the rams are actuated by timers 94 under control of a logic system 102 which also allows pulses from an oscillator 88 to be passed by a gate 86 to counter 90 between the time A when the transducer 42 senses a sample load and a time B at which this sample load has been reduced by a predetermined fraction. This latter time B is determined by a comparator 84 which compares the output of the transducer 42 with a signal representing a predetermined fraction of the transducer output at time A. The number of pulses counted by counter 90 is thus representative of the load relaxation rate of the material.

Title: Improvements in distilling or roasting plant and apparatus more particularly intended for the medium and low temperature distillation of carbonaceous materials
IPC: C10B1/10
Filed: 1921-01-14
Abstract: 178,537. Nielsen, H. Jan. 14, 1921. Rotary furnaces.-In medium or low temperature carbonization a retort consisting of two or more concentric tubular members is used, in which the carbonaceous material travels through zones of gradually increasing temperatures in direct contact with and in the reverse direction to the heating-medium, which gives up its sensible heat but is not itself burnt. The carbonaceous material is fed from hopper a to the outer tube d, its direction being reversed by fixed shovels f<1>, f<2> and propelled thereby into the inner tube f, which may be conical. The whole retort is rotated by rollers q, the material thus being made to pass continuously from end to end by gravity if the tubes are inclined, or if they are horizontal by means of baffle-plates forming continuous longitudinal or screw-like channels, or alternatively by means of a helix fixed to the interior surface of the outer tubular member d or the exterior surface of the internal tubular member f. The latter may also be provided with a helix on the inside surface, or with shelves g to carry the carbonaceous material up to the crown of the tube, ensuring a better contact with the heating-medium. The inner tube f may be lined with fire-brick where the temperature is highest, that is, at the end adjacent to the inlet pipe i through which the heating-medium, preferably producer gas, enters. The carbonized material is collected in an annular chamber j and removed through the doors k. The mixture of heating and evolved gases may be withdrawn, from various points along the length of the retort, through off-take pipes l, and conducted by means of the pipes m and the rotating gas-collecting pipe n, to a dust-chamber o'.
