Title: Improvements in friction brakes
IPC: B60T13/74
Filed: 1930-04-07
Abstract: 352,936. Brakes. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Warner Electric Brake Corporation; 449, Gardner Street, South Beloit, Illinois, U.S.A.) April 7, 1930, No. 10969. [Class 103 (i).] Band ; electric and magnetic.-In a friction brake in which the two ends of a brake band abut against a fixed stop, and in which the ends are forced apart so that the band engages a rotating drum and produces a selfenergizing action in the whole length of the band, an additional control applies pressure at an intermediate point so as to produce a self-energizing action in either portion of the band on opposite sides of the point of application depending on the direction of rotation. In the construction' shown the brake is applied in either direction of rotation by frictional drag between the members of an electromagnet. A ring 19, I-shaped in cross section, with a winding 21 between its two poles 22 constitutes the magnet proper and is circumferentially slidable on the cylindrical portion 24 of a fixed anchor plate 11. When energized, the ring engages the armature member 18 secured to the brake drum 8 whereupon one or other of two projecting lugs 25 on the ring engages a corresponding shoulder 26 on one end of the brake band 12. The other end of the band abuts against a fixed stop 16 and the band with its segmental friction lining 14 is thus expanded into full engagement with the drum 8 against the action of a return spring 17. The additional control comprises a shaft 27 mounted on the anchor plate 11, and carrying an arm 32 with a roller 34 which bears against the internal surface of the brake band when the shaft 27 is rotated. The roller permits the band to move freely in a circumferential direction until checked by the stop 16.

Title: Method and apparatus for the discharge of molten material from gas producers or the like
Inventor: SCHIERENBECK JULIUS
IPC: C10J3/08
Filed: 1955-04-15
Abstract: 800,812. Gas producers ; discharging molten residues. HOHLENSCHEIDUNGS-G.m.b.H. April 15, 1955, No. 10980/55. Classes 51 (1) and 51 (2). A method of controlling the continuous discharge of molten material from gas producers &c. utilizes means which creates a pressure, acting at the slag discharge opening mouth, which exceeds, and operates against, the gas pressure in the producer. In the producer shown, slag is discharged through an outlet 2, Fig. 1, into a water bath 26, and the resulting granulated material is moved to a conveyer 11, Fig. 2, by a conveyer 8 operating in a waterfilled trough 7. The bath 26 is in a pressure chamber 5 in which the pressure is kept, during producer operation, at a value higher than that of the gas in the producer. Variation in the slag level 3 or 3<SP>1</SP> is effected by varying the water head h1 in the slag disposal system. The space above the water in the chamber 5 is filled with steam, evolved, after an initial introduction of steam, through a valve-controlled opening 14 on starting up the producer, as the molten slag drops into the bath. Steam surplus to chamber pressurizing requirements is passed through a pipe 16 and spiral tube arrangements 22, 22<SP>1</SP>, 22<SP>11</SP>, to cool the hot gases leaving the producer through a duct 23. The steam, which passes from the arrangement 22<SP>11</SP> to the producer via a nozzle 25, is also used to heat the producer air supply in a duct 27<SP>1</SP>. Make-up water is fed to the chamber 5 and the slag disposal system through a valve-controlled main 17. In another producer, the slag passes from the chamber 5, Fig. 3, to a chamber 29, Fig. 5, at the top of which is an outlet for slag discharge on to the conveyer 11. The level of the outlet, which may be varied, determines the surface level of the slag in the producer. Prior to furnace operation, the chambers are heated by a gas flame introduced and withdrawn through pipes 32, 33, respectively, whilst on cessation of operation the plug is drained-off through hole 34. In applying the invention to a producer in which iron smelting is effected, the iron and slag may be discharged by means of the devices of Figs. 3, 5, and 1, 2, respectively.

Title: Improvements relating to the isomerization of hydrocarbons
IPC: C07C5/27
Filed: 1940-06-27
Abstract: 542,995. Hydrocarbons. STANDARD OIL DEVELOPMENT CO. June 27, 1940, No. 10982. Convention date, Aug. 26, 1939. [Class 2 (iii)] Normal paraffin hydrocarbons are isomerized by contacting at a temperature below 400‹F. with a Friedel-Crafts' metal halide catalyst modified with an alkali metal halide. Catalysts mentioned are the double compounds of aluminium chloride with sodium chloride or bromide and of aluminium bromide with sodium or potassium chloride. The catalysts are preferably prepared by melting the two components together in the ratio of 1.1 to 2.5 mols. of aluminium chloride or equivalent per mol. of sodium chloride or equivalent ; they may be mounted on such inert carriers as silica gel, active carbon, asbestos, clay, pumice or alumina. When exhausted, the catalysts may be re-activated by treatment with a hydrogen halide, a free halogen, or an alkyl halide. As the catalysts are also suitable for alkylation with olefines, the isomerization process may be combined with one of alkylation. Examples are given of the treatment of n-butane, either saturated with water or mixed with hydrochloric acid, using sodium aluminium chloride as catalyst ; the treatment of n-pentane is also mentioned. Specifications 524,252 and 534,456 are referred to.

Title: A process for working vapour engines
IPC: F01K25/06
Filed: 1927-04-25
Abstract: 283,037. Irinyi, A. April 25, 1927. Vapour engines.-The heavy vapours of liquid fuels which decompose at a high temperature, particularly gasoline, benzol, toluol, and light oils forming a mixture of benzol, toluol and xylol, and which have a low heat of evaporation, a high specific heat, and high molecular weight, are mixed with a relatively small quantity of steam or ethyl or methyl-alcohol to avoid decomposition of the heavy vapour. The mixture is used in an engine. When water and benzol are evaporated at 20 atmospheres, the vapour comprises 19 per cent steam and 81 per cent benzol by weight. The air, saturated with fuel and water vapour, pumped out of the condenser can be used for heating the generator, or in an internal-combustion engine. The mixed liquids can be used initially in an internal-combustion engine radiator, the engine exhaust being used for heating the evaporator.

Abstract: 551,190. Boring and facing machines. ASQUITH, Ltd., W., and JOHNSON, A. Aug. 30, 1941, No. 11097. [Class 83 (iii)] In a horizontal boring and facing machine a clutch is provided for disengaging the table carriage from the traversing gearing used for screwcutting and resetting the table with the aid of a micrometer dial adjustment for cutting the sides of threads, adjustment through one division serving to move the table through 0.001 inch or thereabouts. In the application to the machine described in Specification 546,251 and as shown in Figs. 1 and 6a, the carriage 2 movable in the column 3 carries a boring-spindle 1 and also a face plate carrying facing slide 5. The carriage is provided with the system of control dials described in the above-mentioned Specification. When the main control dial A has been set for screwcutting, drive is transmitted from the input shaft 10 through the shafts 11, 20, 21, 22, as shown by the arrows in Fig. 6a to the reversing gearing d<SP>6</SP>, d<SP>7</SP> and thence to shaft g<SP>8</SP> extending into gear box g<SP>9</SP>, Fig. 1. The hand wheel 8 is connected through gearing 8a, 8b, shaft f<SP>5</SP>, clutch h<SP>5</SP>, and gearing h<SP>12</SP>, h<SP>14</SP> to a screw h<SP>16</SP>, Fig. 6b, giving axial spindle movement. A gear f<SP>6</SP> is connectable to shaft d<SP>5</SP> for power feed. When the main dial is set for screw cutting, the gearing h<SP>12</SP>, h<SP>14</SP>, Fig. 6b, is disengaged. The shaft f<SP>5</SP> is connected to a shaft 5a geared through shaft 5c and gears 5d, h<SP>14</SP> to a rack 5k on the facing slide. The gear box g<SP>9</SP> includes, as shown in Fig. 2, shaft g<SP>12</SP>, multiple gear g<SP>14</SP>, clutch members g<SP>17</SP>, gears g<SP>19</SP>, g<SP>20</SP> and change gears g<SP>22</SP>, g<SP>24</SP>. The drive is thus conveyed as shown by the arrows to a shaft g<SP>27</SP> connected to the longitudinal shaft 7b from which table drive for screw-cutting is derived through the train shown in Fig. 4. A shaft 30a of this train carries a micrometer dial 30 and is connected by spiral gears to a stationary screw shaft 31, by which longitudinal movement is imparted to the work W, Fig. 1. A handle 35a, Fig. 1, also actuates one member of a finely toothed clutch 36b, Fig. 3 (not shown) the movement of the dial 30 through one graduation serving to rotate the clutch through the space of one tooth. The clutch is mounted on a shaft 36c connected to the shaft 7b. When it is required to impart a side feed to the tool the clutch 36b is disengaged by means of the handle 35a and the micrometer 30 turned one or more divisions to impart longitudinal table movement through the screw 31. For fine setting of the tool in a radial direction the hand wheel 8 is provided with a micrometer head 8a, Fig. 1.

Abstract: 729,426. Gas turbini plant. SOC. RATEAU, and ANXIONNAZ, R. May 11, 1951 [July 3, 1950], No. 11199/51. Class 110 (3). To increase the power output of a gas turbine plant comprising a main turbine compressor means which supplies turbine exhaust gas to a mechanically independent power turbine an auxiliary compressor mechanically independent of the main turbine compressor means is arranged to deliver compressed air to one or more compressed air inlets of the main turbine compressor means and the volume of turbine exhaust gas from the main turbine compressor means for the power turbine is increased by augmentation, by gas or by expansion through an auxiliary, turbine. In the arrangement shown, Fig. 1, the power turbine c is fed with turbine exhaust gas by a turbine compressor plant a, b. When increased power is required the auxiliary turbine compressor d, e is put into operation. Air bled from the compressor d is passed through a cooler 15 to the intake of the compressor a, and gas bled from the turbine e is mixed with the exhaust gases from the turbine b before they enter the power turbine c. To prevent choking of the low-pressure stages of the turbine c, gas may be bled from this turbine at 13 and passed back to the turbine e. More than one bleed may be provided on the turbine c, each bleed being connected to a different stage of the turbine e. In a modification, Fig. 4, air is fed to the inlet of a compressor a<SP>1</SP> by an auxiliary compressor d<SP>1</SP> driven by an auxiliary turbine e<SP>2</SP>. The volume of exhaust gas from the turbine b is increased by the addition of combustion gases from a combustion chamber 8 supplied by compressors d<SP>2</SP>, d<SP>3</SP> driven by an auxiliary turbine e<SP>1</SP>. Gas bled from the turbine, c at 20, 21 is passed to the turbine e<SP>2</SP> and mixed with the exhaust of the turbine e<SP>1</SP> respectively. To further increase the power, the heat exchanger 22 may be by-passed on both the air and gas sides. In a modification of this arrangement, the volume of exhaust gas is increased by mixing 'air from a further independent compressor driven by an auxiliary turbine fed with gas bled from the power turbine c. In another modification, with a reheating chamber between' the turbines b and c, the exhast gas from the turbine b is expanded in an auxiliary turbine driving the auxiliary compressor before use in the turbine c. Specifications 490,198 and 619,259 are referred to.

Title: Improvements in means for testing the accuracy of watches
IPC: G04D7/12
Filed: 1947-04-28
Abstract: 637,659. Testing timepieces. GREENING, H. B. April 28, 1947, No. 11328. Convention date, May 18, 1946. [Class 139] [Also in Groups XX, and XXXV] A means for testing watches comprises a microphone adapted to transform the sound waves produced by the ticks of a watch into electrical impulses, means for amplifying the electrical impulses of the microphone, a rotatable disc having circumferentially spaced markings thereon, means actuated by the amplified electrical impulses for effecting rotation of said disc, a second microphone adapted to transform the sound waves produced by the ticks of a watch into electrical impulses, means for amplifying said electrical impulses, and means actuated by said amplified impulses of the second microphone for producing regular periodic light flashes to illuminate the marked surface of said disc. The ticks of a " standard " watch are picked up by a microphone A which converts them into electrical impulses which are amplified by valves C and D before being passed to a valve E the output of which is connected to an electromagnet F which is therefore periodically energized to attract its armature H. The armature H carries a contact M which when the armature is attracted by the electromagnet F abuts a contact N to close the circuit to and cause the energisation of an electromagnet K which thereupon retracts the armature H from the electromagnet F. The armature H is therefore continuously oscillated and through a crank I rotates a disc J on a shaft O. The disc J has eight radial markings Q which can be viewed through slots in a disc Z rotated in similar manner to the disc J by an armature X controlled by the electrical impulses from a valve V connected through the valves U and T to a. microphone R which picks up the ticks of a watch to be tested. A lamp 1, Fig. 5, projects a beam of light through the uppermost slot in the disc Z on to the disc J. illuminating the uppermost mark Q. If the two watches are in agreement the illuminated mark Q appears to be stationary opposite the zero of a stationary scale 5. If, however, the watch being tested is " fast " or " slow " the illuminated mark Q will appear to move away from the origin of scale 5 in one direction or the other. If desired the slotted disc Z may be omitted and a lamp periodically energized to illuminate the disc J. In this case the impulses from the second microphone are amplified and multiplied by electronic means before passing to the illuminating lamp.

Filed: 1975-03-19
Abstract: 1463254 Riveting R F HIRSCH 19 March 1975 [25 July 1974] 11335/75 Heading B3U A blind riveting tool comprises a magazine 100 for laterally feeding rivets 3 into a housing 11, a slide member 30 for advancing a rivet 3 from the magazine 100 to a setting position, means 60, 61 for releasably locking the slide member 30 at the setting position, mandrel gripping jaws 38, 39 carried by and movable relative to the slide member 30 and a slide member 15 for pulling the jaws 38, 39 to set the rivet 3. In operation, the slide member 15 is moved into contact with the nose 12 of the housing 11 by a piston 86 and the slide member 30 is moved by a piston 76 to push a rivet 3 from the magazine 100 formed by corrugated paper to its setting position. The leading end of the slide member 30 is bifurcated to form jaws 32, 33 which grip the rivet mandrel 7 as well as gripping jaws 38, 39 mounted on spring biased rods 44, 45 movable in bores 48, 49 in abutments 46, 47 on the slide member 30. The slide member 30 is locked in its forwardmost position by pawls 60, 61 engaging the abutments 46, 47 so that when the fluid supply to the pistons 76, 86 is reversed only the outer slide member 15 is moved rearwardly causing a shoulder 16 at its front end to pull the gripping jaws 38, 39 rearwardly to set the rivet 3. During the rearward movement of the slide member 15, an arm 121, Fig. 2, is pivoted by an abutment 127 causing the magazine 100 to be advanced to align a space between a pair of magazine corrugations, Fig. 9, with the broken mandrel 7. When abutments 22, 23 on the slide member 15 unlock the pawls 60, 61, the slide member 30 is moved rearwardly causing first the jaws 38, 39 and then the jaws 32, 33 to be spread apart by magazine guide plates 111, 112 releasing the broken mandrel 7 which is deposited between the magazine corrugations. The arm 121 is pivoted again by an abutment (133) (Fig. 11, not shown) on the slide member 30 engaging a pivotable arm 130 causing the next rivet 3 in the magazine 100 to be aligned with the slide member 30 and the broken mandrel 7 to be pushed along until it reaches a discharge shoot 116.
