Title: Improvements in or relating to derricks, cranes and the like lifting apparatus
IPC: B66C23/60
Filed: 1934-12-10
Abstract: 428,029. Jib-cranes. BLOW, E., Oberon Wharf, Queen Street, Hull. Dec. 10, 1934, No. 35385. [Class 78 (iv)] A crane, derrick, or like lifting- apparatus is arranged to be slued automatically by the operation of hoisting the load. Fig. 1 shows a winding- rope passing round pulleys 14, 16 on the jib and post respectively, to a winding-drum 17. The slueing rope 19 passes from a sliding sleeve 20 on the hoisting-rope round the pulley 18 to a ground-anchor spaced laterally from the post. On raising the load, the stop 22 on the hoisting-rope engages and carries the sleeve 20 with it, thus shortening the length of the slueing-rope between the anchor and the pulley 18 and slueing the jib towards the anchor. In some cases a second rope shown in dotted lines may be passed round a pulley a furnished with a rope-grip and mounted at the foot of the post, thence passing to a hanging weight b on the post. The weight then takes up the slack as the jib is slued, but the rope-grip becomes effective to prevent movement in the reverse direction, thus maintaining the jib in the slued position. Fig. 3 shows a modification of the above arrangement for slueing to either side at will. Two pulleys 23 with rope-grips are mounted at opposite ends of a bar 24. By fixing either slueing rope 19 by hand-operation of the corresponding rope-grip, that rope becomes effective to cause slueing, while the other rope moves freely over its pulley and is kept taut by the weight 29. A spring may be incorporated in the slueing-rope to take up the shock occurring on the initial tension.

Title: Improvements in or relating to methods of making heat treated white cast iron and the improved iron produced thereby
Filed: 1932-12-16
Abstract: In a method of heat treating white cast iron, a retarding agent such as manganese is added to a white iron melt of normal composition, and the cast iron produced is heated to a temperature above the critical temperature for a sufficient length of time to decompose the cementite into iron and temper carbon, is then cooled to a temperature below the critical temperature and then reheated to a temperature below the critical temperature so as to permit the retarding agent to effect a retarded reaction of decomposition or readjustment of the pearlitic cementite to produce a spheroidized structure in the iron.  As applied to a white cast iron containing 1,29-0,7 per cent of silicon, and 0,6-1,5 of manganese, and the difference between the manganese content and twice the sulphur content is between 0,4 and 1,25, the iron is heated to 1700 DEG  F. for 18-36 hours, cooled and heated again to 1150-1375 DEG F.  The heatings may be carried out in a non-oxidizing atmosphere.  In place of or in addition to the manganese, other retarding agents such as chromium, vanadium or molybdenum, in small quantities up to ,25 per cent, may be used.

Title: Improvements in or relating to induction motors
IPC: H02K16/02
Filed: 1959-10-22
Abstract: 921,652. Electric motors. M. B. HUTSON. Oct. 22, 1959 [Oct. 22, 1958], No. 35822/69. Class 35. [Also in Group XXIV] A squirrel - cage induction motor comprises a stator 38, a driving rotor mounted to drive a drive shaft 16, 17 and comprising first and second rotor sections 20, 21, and a further rotor 31 of magnetic material mounted in axial alignment with the driving rotor, the further rotor being rotatable relatively to the drive-shaft at least at low speeds of the driving rotor and the motor characteristics being variable by mutual relative axial displacement of the stator and driving rotor. As shown, the stator is axially movable by being secured to a travelling nut 42 moved by a hand wheel 44 via gearing 45 and a feed-screw 43. The rotor first section 20 nas a low resistance winding formed between end and intermediate rings 23, 24, and the second section 21, of half the axial length of 20, has a high resistance winding formed between intermediate and end rings 24, 26 via conductors 29 and individual resistances 28 situated remotely from the rotor in the chamber of a cooling pump 27. The rotor 31, which normally is free-running on a plastic or oil-impregnated bearing-ring 35, is coupled to the shaft 16 as the latter approaches its full speed by the centrifugal force on a pin 46 normally retracted by a tension-spring 47, whereby fan blades 37 carried by the rotor provide supplementary cooling. The output of the motor may be varied gradually from zero when the stator covers rotor 31, through a high starting torque high slip condition when covering rotor section 21, to a constant torque at low slip when covering rotor section 20. The closed housing, which may be explosion proof, is formed by a frame 10 and end bells 11, 12 provided with radiating ribs 48, 49 cooled by an outside, shaft-driven fan 50 which draws in air through cowling openings 52 and discharges it at 53. The resistances are enclosed by hollow supporting fins 56 which rotate with the shaft 17 and circulate gas or liquid coolant from a conduit 15, through the pump 27, to a discharge conduit 25. The hollow portion 17 of the drive-shaft is secured to the solid portion 16 by spider arms 18 and circular end-plates 19. A hoist lifting hook may be driven by two such motors connected to run in opposite directions and with full voltage applied to the stators, forward and reverse running being controlled by simultaneous shifting of the stators.

Title: Improvements relating to pressure regulators for fluid pressure apparatus
IPC: G05D16/10
Filed: 1931-12-31
Abstract: 394,694. Brakes ; air compressors. TOMLINSON, A. V., 65, Victoria Street, London.-(Compagnie des Freins Westing- house ; 23, Rue d'Athenes, Paris.) Dec. 31, 1931, No. 36117. [Class 103 (i).] In order that an ample supply of compressed air may be available in the main reservoir of a fluidpressure brake system for supplying the brake pipe in releasing the brakes, two pressure regulators for controlling the power circuit of the electrically driven compressor by which the reservoir is charged, are provided one regulator adapted to establish a pressure in the reservoir higher than the normal being rendered operative when the driver's brake valve is in positions such as lap, service, or emergency corresponding to an application of the brakes and the other which establishes the normal pressure being rendered operative in other positions of the driver's valve such as release or running. As shown in Fig. 1, two regulators 5, 6 responsive respectively to normal and higher pressures in the main reservoir 1 and each operating a switch 3, 4 in the compressor power circuit are connected to a valve device 7 operated by.a piston 11 constantly subject on its upper face to the pressure in the reservoirs and on its under face to the pressure in a chamber 10 connected by a pipe 14 to the driver's valve, in brake application positions of which it is connected to the main reservoir so that the valve is held in the position shown, by the spring 15. The regulator 5 is in this case connected to the atmosphere at port 17 and is thus inoperative. In release positions of the driver's valve, however, the pipe 14 is connected to the brake pipe so that the piston 11 is moved downwards to connect the regulator 5 to the reservoir thus rendering it operative. In a modification the higher pressure regulator 6 instead of being permanently connected to the reservoir 1 is connected by the valve to atmosphere when the regulator 5 is connected to the reservoir. In further modifications, the two regulators control a common switch.

Title: Vehicle propulsion system
IPC: A63G25/00
Filed: 1955-12-16
Abstract: 804,499. Amusement apparatus. CHEREAU. A. Dec. 16, 1955, No. 36128/55. Class 132(1) A vehicle propulsion system comprises a track made up of a plurality of surface elements in the form of separate plastic slabs which are small with respect to the area of the track and separable from each other, each having a web or core incorporating electric conductors for generating an alternating magnetic field and inductive means carried by the vehicle and magnetically coupled with said field to produce an electric voltage which energizes an electric motor on the vehicle to drive the vehicle. Slabs 2 are laid on wooden planking or the like and consist of a core or web of magnetic material overlaid with small elements e.g. of iron silicon alloy, so as to form a network of shallow grooves 13 between the elements to receive insulated conductors. These elements 2 are substantially flexible or resilient and are made of plastic sheet material which may incorporate a magnetic filler material. The conductors may be incorporated in the elements during moulding. The conductors are so arranged that, when the ends are connected to an alternating current supply, a magnetic field is created extending substantially parallel to the upper face of the track. Fig. 3 shows part of a continuous composite conductor having a series of loops 4, 5 6 and 4a, 5a, 6a and linear parts 10, the area of the cross section of the conductors forming parts 10 being twice that of the conductors forming the sides of the loops. Each loop fits into the squares or the like formed by the intersecting grooves 13 and the conductors are wound on the slabs 2 as shown in Fig. 2, the dotted lines indicating the parts 10 underneath the elements and each groove containing the adjacent sides of two successive series of loops. The vehicle carries a four legged rectangular core whose lower horizontal leg is as low as possible and may engage the surface. The secondary winding 17 is wound e.g. on the uppermost leg of core 18 and the induced voltage is used to drive a motor 20.

Title: A combination of central buffer coupling and draw gear on a rail vehicle
IPC: B61G7/10
Filed: 1958-11-11
Abstract: 866,585. Railway vehicle draw gear. FISCHER A.G., GEORG. Nov. 11, 1958 [Nov. 21, 1957], No. 36219/58. Class 103(5). A central buffer coupling 1 having a spring buffer housing 2 provided with brackets 3, rests on a roller 4 rotatably mounted on a shaft 5A slidably supported by compression springs 6 from arms 8 mounted on the carriage structure 14. A housing 9 having an annular flange 9A is mounted on a bearing 10, and a vertical shaft 18D having a ball joint 17 extends between bushes 18C disposed in plates 18A and 18B forming part of the carriage structure. A bolt 15 passes up through the shaft 18D and is provided at its top with a centring plate 13 secured against rotation and having on its underside knife edges 12 co-operating with notches 11 formed in the top of the housing 9. The bolt 15 is biased downwardly by an adjustable spring 16 fixed thereto. In order to turn the coupling and the mounting 9, the knife edges 12 must move up the sides of the notches 11 against the force of the spring 16 which exerts a restoring and centring movement on the complete mounting. The weight of the coupling and mounting is balanced by the springs 6, 16, and slight turning movement is possible about the longitudinal axis causing the roller 4 to incline. In a modification the underside of the centring plate and the upper side of the co-operating surface of the mounting 9 are provided not with knife edges and notches but with arcuate tracks which are deepest in the middle and shallow towards their ends. In each of these pairs of tracks a ball is confined which is forced to the middle by the compression spring to centre the coupling.

[Also in Division G5] A cyclic controller comprises a band A which may be of magnetic tape having longitudinal perforations, which when coinciding with a window in a guide B allow an arm E to move and actuate a micro-switch. To ensure synchronization between the controller and, say, a machine it is controlling a second micro-switch M2 is provided, which is arranged to close a contact 14, and a switch J operated by the machine is thrown to position 16 at the end of each cycle, hence providing a complete circuit which initiates the next cycle. If the tape is late, the micro-switch M2 will be in position 10 until the tape moves into synchronism, during which period the machine will be stopped. During the running of the cycle, switches M1, M2 may send a series of impulses through switch J in position 12 to the machine. The magnetic tape may also carry magnetic signals which are picked up by corresponding reading heads. The tape may be of the endless type.

Abstract: 522,705. Setting projectile fuzes. STONE, A. A., and MOLINS MACHINE CO., Ltd. Dec. 13, 1938, No. 36348. [Class 9 (i)] Apparatus for setting time fuzes of the kind having a fixed and a rotary ring, comprises two carriers having axes coincident with the axis of the projectile and having elements adapted to engage within notches in the rings, means to rotates both carriers in the same direction and at the same rate for an angular distance greater than 360 degrees, means to prevent engagement of the second locating element with the fixed ring during the first 360 degrees and means responsive to such engagement thereafter to interrupt the driving means. The locating means comprises spring-pressed pawls 16, 17 carried on discs 5, 6 mounted for rotation within a fixed cylindrical casing 1 part of which forms an internal gear 2. A ring 3 also mounted within the casing 1 is formed with an internal gear 4. Pinions 8 and 7 carried by the discs 5, 6 respectively mesh with the gears 2, 4 and also with sun gears 9, 10 driven from a shaft 13 through gears 11, 12 so that the discs rotate together. A cam 24 also driven from the shaft 13 acts on one end of a pivoted lever 21 to control the axial position of the sun gear 10. During the first complete revolution of the discs, the sun gear 10 is in a position such that a groove therein engages an abutment 18 on the pawl 17 preventing the pawl from engaging the notch in the fixed ring. The pawl 16 however engages the notch in the movable ring. After the first revolution, the sun gear 10 is withdrawn, the pawl 17 engages the fixed ring and the rotation of the shaft 13 is halted, clutch teeth 15 moving apart under the strain. Before a second setting operation, the shaft 13 must be turned back to the original position, a stop being provided for this purpose. The angular relation between the pawls 16, 17 may be adjusted by rotating the disc 6 through a graduated handwheel 27, worm 270, worm wheel 28 and spur gear 29 which rotates the ring 3.

A lighting fitting comprises a lamp 1, a moulded transparent block 2 which surrounds the lamp and is formed with annular prisms on its outer surface, and a reflector 6 which receives upwardly directed light from the lamp and re-directs it downwardly so that it does not fall on the prisms. The prisms are of two kinds and are so arranged that the two large upper prisms 4, 5 operate by total internal reflection whilst the small lower prisms 3 operate by refraction only, the lower faces of the large prisms being shaped so that the light leaving the prism 4 is divergent and the light leaving the prism 5 is convergent and thereby clears the edge of the prism 4. The reflector 6 has a section composed of a plurality of circular arcs, the arcs nearer to the axis of symmetry and to the outer rim of the fitting being of smaller radius than the intermediate arcs. The reflector is supported by rods 14 secured to a rim 9 on the mast 10, and the spaces between the rods are filled by transparent sectors 18 which rest in slots 12 in the rim and are held at the top by a member 21 movable upwardly against the bias of springs 23 to release the sectors. The block 2 is supported on the member 21 by arms 25. The inner surface of the block may be provided with vertically extending prisms (Fig. 5, not shown) so that the polar curve of light intensity takes on an elongated shape suitable for street lighting. Cooling air enters the fitting through holes 11 and leaves through the gap between the top of the sectors and the reflector.

An aperture beam mask, in particular a shadow mask assembly 20, 22 in a colour cathode-ray tube, is mounted in a tube adjacent the screen by cantilever springs 25, 26, 27 secured to the mask and to studs 30 31, 32 on the envelope, and at least one spring, e.g. 27, is connected to the mask at such a distance from the radial axis of symmetry 44 that thermal expansion of the mask along the side transverse to axis 44 is compensated by thermal expansion of the mask parallel to axis 44 and of the spring which is at a predetermined angle to the mask, which expansions produce a resultant shift of the mask transverse to axis 44, see Figs. 5, 6 (not shown), so that there is no net change in the position of axis 44. As shown, all three cantilever springs are mounted in such a relationship with their respective axes of symmetry so that upon thermal expansion of the mask alignment of the centre of the screen is maintained and radially uniform misalignment of the mask and phosphor pattern on the screen only results, which misalignment may be satisfactorily compensated.
