Title: Protected remote alarm system
Inventor: LEE JOHN GWYN WILLIAM
IPC: G08B13/22
Filed: 1959-10-15
Abstract: 959,664. Intruder alarm systems. DE HAVILLAND AIRCRAFT CO. Ltd. Oct. 13, 1960 [Oct. 15, 1959], No. 34922/59. Heading G4N. An alarm system operated by interruption of an electric circuit of by the variation of capacitance in an associated circuit caused by the presence of an intruder comprises a normally operated relay 14 contained in the device to be protected 10, which keeps closed a switch 16 in a transmission circuit 20, 22 between the device 10 and an alarm unit 12. The transmission circuit includes two pulse generators 28, 30 (with a mark-space ratio of one to one) connected in series but with a time delay network comprising unit 26, capacitor .18 and resistor 24 positioned between them. Consequently pulses from generator 28 are delayed sufficiently to cause generator 30 to produce pulses which lie within the "space" period of pulses from generator 28 and thus an essentially D. C. current for maintaining relay 32 is produced. If the capacity of the transmission circuit is altered, the delay of pulses from generator 28 will be changed and relay 32 will fail or if the circuit of relay 14 is opened, the alarm will again be given.

Title: Improvements relating to internal combustion engine cylinders and valves
IPC: F01L3/06
Filed: 1927-12-28
Abstract: 307,996. Bailey, R. W., and Metropolitan-Vickers Electrical Co., Ltd. Dec. 28, 1927. Cylinders receiving liquid fuel.-In a cylinder having a combustion chamber which is circular in transverse section, the axis AA of an air inlet valve 1 is inclined to the radial plane BB; the valve seating 3 is formed in a recess 4 and screened on one side and thus the air is whirled in the direction of the arrows b, c. The inclination of the valve is preferably such that the dimension a is half the diameter of the valve head. The face of the valve when open may be flush with the edge of the recess 4, or the recess may be set back and formed so as to cause the air flowing past it to be deflected in the direction of the arrows c. Two or more valves may be thus arranged symmetrically or not in the combustion chamber and they may slope, as shown in Fig. 5, towards the cylinder head which is preferably conical and has a large central exhaust valve 7; pockets 5 are formed in the piston to clear the valves. The liquid-fuel valve 8 is arranged to deliver fuel as shown in Fig. 1. The invention is specially applicable to an engine for producing combustion products for use in a separate prime mover as described in Specifications 232,278, 244,215, and 245,541, [all in Class 7 (ii), Internal-combustion engines, Arrangement &c. of].

Title: Improvements in the driving mechanism of electrically driven paper machines and the like
IPC: H02P5/74
Filed: 1927-12-28
Abstract: 308,380. Harland Engineering Co., Ltd., and Warburton, F. G. Dec. 28, 1927. Driving arrangements.-In the driving of the drying cylinders of a paper machine, the freedom of the felts to shrink or stretch at different parts of their travel is ensured while the corresponding points of the upper and lower felts are driven at approximately the same speed. This is effected by driving each dryer or group of dryers by means of a separate motor and by coupling up corresponding motors. The interlocking may be effected mechanically and/or electrically. The corresponding upper and lower dryers may be geared together by gear wheels of equal size or they may be coupled up as described in Specification 22897/14, [Class 38 (iii), Electric motor control systems &c.]. This arrangement is shown in Fig. 2, where the motor 17 driving the lower dryer 14 is coupled through gearing and speed regulating mechanism 24 to the motor driving the dryer 10. The motors driving two dryers may be coupled electrically by providing the motors with interconnected slip rings in known manner. As shown in Fig. 4, the motor driven dryers 28, 29 may be coupled up by auxiliary induction motors 31, 32, fed from supply mains and connected in known manner so that their speed due to their periodicity is in each case zero but always equal within the limit of their own torque capacity if such induction motors are rotated mechanically by some other source of power.

Filed: 1931-12-19
Abstract: 373,946. Combined brake and engine control. OTTO, W., Kitzeberg, near Kiel, Germany. Dec. 19, 1931, No. 35213. Convention date, Dec. 22, 1930. [Class 103 (i).] Comprises brake-and-throttle controlling- means in which a member 20 carried by the brake pedal 19 has at one end a spring-controlled tripping pawl 21 adapted to act on the accelerator pedal 22, the pivotal axes of the pedals being so arranged that when the brake pedal is depressed the accelerator pedal is operated to open the throttle but when the brake pedal reaches a certain position the pawl 21 disengages from the accelerator pedal and cannot re-engage it until the brake pedal has returned to its initial or " off " position. In the construction shown the brake pedal is pivoted at 24 and the accelerator pedal moves in a horizontal line ; thus the tip of the pawl 21 moves in the circular arc shown and disengages from the accelerator pedal when the latter reaches the position shown in broken lines in Fig. 1, this position corresponding to full throttle. The pawl 21 is depressed by a spring 35 and may be raised, to disengage from the accelerator pedal, by means of a sliding plate 10, chain 14, and bell crank 15 engaging a pin 31 on the pawl 21. Thus to operate the brake without operating the accelerator the driver first moves his foot laterally on the brake pedal and slides the plate 10 thus lifting the pawl 21.

Title: Solid porous water-repellency-imparting preparations and process for their manufacture
IPC: D06M13/188
Filed: 1959-10-19
Abstract: A solid water-repellency-imparting preparation having a porous structure is made from a blend of wax (e.g. paraffin or slack wax) and an organic water-repellant material which is soluble in an organic solvent.  The blend of wax and organic water-repellent material may be rendered porous by introducing an inert gas into the melted blend at a temperature above the solidification point thereof and cooling the foamed product thus obtained until it is solid.  The inert gas, e.g. air, carbon dioxide or nitrogen, may be introduced into the melt with the aid of frits or alternatively an inert-gas-yielding substance may be added to the melt.  Thus solid carbon dioxide or a nitrogen-yielding organic or inorganic substance (e.g. benzenesulphohydrazide or azohexahydrobenzonitrile) soluble in organic solvents may be added to the melt.  A small proportion of organic solvent, e.g. 1-10% by weight of benzene or an aliphatic or chlorinated aliphatic hydrocarbon, may be incorporated in the melt. The preferred organic water-repellent material is an alcoholate of a polyvalent metal, e.g. aluminium, zirconium or titanium.  These compounds may be used in a form in which one or more of the valencies of the metal are satisfied by monobasic organic acidic substances such as carboxylic acids (e.g. fatty acids or aromatic monocarboxylic acids) or their anhydrides, monosulphinic acids, monosulphonic acids, phosphonic acids or organic monosulphuric acid- or phosphoric acid-esters.  The alcoholates may also be branched by metaloxygen linkages (i.e. one or more valencies of the metal may be satisfied by an oxygen atom connected to a further polyvalent metal atom and the remaining valencies of this second metal atom may be satisfied in the same ways as those of the first metal atom).  These modified alcoholates may be stabilized to a considerable extent by keto-enol compounds (e.g. acetoacetic ester) to prevent premature decomposition by moisture. Other organic water-repellent materials mentioned are neutral salts of polyvalent metals with lower and higher carboxylic acids, basic hydroxyl-containing salts, carboxylic acid anhydrides, e.g. stearic acid methylolamide, N,N1-ethylene ureas, copolymers of maleic acid or its esters with high molecular weight vinyl ethers, derivatives of polymethylol amino- or polyazirino-triazines (i.e. triazines which contain ethylene imine groups) containing high molecular weight aliphatic groups and high molecular weight organic isocyanates.  Specifications 767,585, 777,466, 780,967, 783,605 and 790,624 are referred to.

Abstract: 1,123,557. Welding by fusion. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 16 Oct., 1967 [9 Aug., 1966], No. 35612/66. Heading B3R. [Also in Division G6] A method of manufacturing a nuclear reactor fuel element comprises supporting at least one curved plate of clad fuel on a mandrel and joining adjacent edges of the plate(s) together by an electron beam welding technique applied in a manner so that a tube with at least one longitudinal seam is formed from the plate(s). The plates are, for example, of U-Al alloy clad with Al and each formed by rolling or pressing a flat plate into a 120 degrees arc. They are clamped between a cylindrical clamp 2 in three arcuate parts 2a and a mandrel 3 of three parts 3a and an expanding device 4 for radially expanding the parts 3a. Longitudinal spaces (5) (Fig. 2, not shown), provide access for an electron beam welding gun when the workpiece is traversed beneath the focused beam position. The body 1 supporting the clamp 2 comprises four plates 6 interconnected by longitudinal ribs 7. The plates 6 are annular and the intermediate ones 6a are divided into three spaced arcuate parts. The clamp parts 2a are carried within the annular plates by cap screws 8. The expanding device 4 comprises a tube 9 to which end fittings 10, 11 are welded, the former slidably carrying a mandrel expander 14 having an annular tapered groove 15 formed in one end face. The end fitting 11 has a similar annular groove 18 and the grooves 15, 18 are used to support the ends of the mandrel parts 3a. These are tapered complementary to the grooves. Movement of the expander 14 towards the end fitting 11 is effected by a nut 13 on the screwthreaded shank 12 of the end fitting 10. The mandrel parts 3a are braced mid-way along their length during clamping of the curved fuel plates by an expanding brace 21 comprising a taper plug 22 secured to the tube 9 and having a slidable complementary tapered socket 23 slit from each end to define resilient fingers. Movement of the socket 23 along and up the taper plug 22 causes it to expand resiliently to brace the mandrel parts. This movement is effected by a transverse pin 24 carried by a head 25 and slidable within slots 26 in the tube 9 and taper plug 22 ; the head 25 is attached to a tube 27 having a screwed end fitting 28 engaged by a screw 29 captive in the end fitting 10. The end fitting 11 has three pins 30 which coincide with the longitudinal spaces (5) and are set to serve as targets for focusing the electron beam.

Abstract: A process for producing or refining boron by a distillation process which comprises reacting material bearing boron, at an elevated temperature and preferably under reduced pressure, with a halide brought to the vapour phase previous to the reaction, thereby to form a lower halide of boron, and recovering boron from the resulting vapour by cooling or absorption.  The halide vapour used may be unsaturated under the conditions of its reaction with the boron bearing material and the temperature of reaction may be higher than the temperature of evaporation of the halide under the conditions prevailing in the apparatus used.  This reaction may be carried out in the presence of vapour or gas inert to the boron. A low boiling or subliming halide or other halogen-containing substance may be employed.  The boron-bearing material should preferably be brought into reaction in a dispersed condition, i.e. in the form of powder or drops of high specific area.  The boron and halide may be condensed in different zones in which case at least two halide condensers may be employed and used alternately as condenser and evaporator, the same amount of halide being used without discontinuing the reaction. Alternatively the temperature of the boron condensing zone may be kept above the condensing temperature of the halide which then remains in the vapour phase. Specification 582,579, [Group II], is referred to.ALSO:A process for producing or purifying a non-volatile metal other than aluminium by a distillation process comprises reacting material bearing the said metal at elevated temperatures, and preferably under reduced pressure, with a reacting halide brought to the vapour phase previous to the reaction, thereby to form the lower halide of the metal, and recovering the metal from the resulting vapour by cooling or absorption.
