Title: Improvements in Spring Starters for Internal-combustion Engines.
Inventor: LINDGREN PHILIP CHARLES
IPC: F02N5/02
Filed: 1917-08-30
Abstract: 118,164. Lindgren, P. C. Aug. 30, 1917. Turning-gear. - In spring turning-gear, the starting - shaft with its driving- pinion is so mounted as to be free from the load of the exterior members and to float upon' a train of gears, of which the outermost is supported by the starter casing. In the form shown, the casing 1 is secured to the frame bar A<1> of the vehicle by a flange 1<a> having a seat for the end e of the crank-case E. The starting-shaft comprises a tubular member 7 carrying a pinion 27 and journaled in ball bearings in the planetary gear train, and a member 2, which passes through the member e without contact, and is slidable at its rear end in e, socket 3 pinned to the engine shaft. The shafts are kept in alinement. by a cone-pointed pin 4<a> within the end of the shaft 2, held by a spring 4 in engagement with a conical socket in the end of the engine shaft. The forward end of the shaft 2 is adapted for engagement with an emergency starting-handle, and carries a slidable member 11 forming a ball race for the rear end of the shaft 7, the balls 2<e> forming a one-way clutch between the two shafts. The power spring 10 is connected at one end to the casing 1 and at the other end to a drum 21 fast on the shaft 7. The reducing- train for winding the spring from the engine comprises a disk 25 journaled in bearings 51 on the casing and carrying planet pinions 29. These engage with co-axial pinions 27, 28 with a difference of one tooth, all but one of the planet pinions having two banks of teeth engaging respectively with the two pinions 27, 28. The pinion 28 is journaled in ball bearings 33 on the shaft 7. In winding the spring, the member 25 is driven by the shaft 2 through clutch teeth 11<b> on the member 11, and the gear 28 is held by a toothed segment on the end of a locking-dog 30 pivoted on an eccentric wrist 31<a> of a rock-shaft 31. When the spring is wound, the clutch member 11 is moved out of engagement with the member 25 by a sleeve 15 having threaded engagment at 15a with the shaft 7, and bearing at its rear end against the member 11. The clutch teeth are slightly undercut to resist the rearward thrust of the sleeve 15, and the rotation of the shaft 7 at first rotates the sleeve 15 and winds a spring 40 connected to the sleeve and to the casing. When the spring 40 is fully wound the sleeve 15 moves longitudinally to disengage the clutch, and the unwinding of the spring augments this movement. For starting, the dog 30 is disengaged from the gear 28 by turning the rock-shaft 31, and the power spring drives the shaft 2 through the one-way clutch 2<e>, 11 between the shafts 2, 7.

Filed: 1940-08-01
Abstract: 540,199. Metallic springs. BRITISH THOMSONHOUSTON CO., Ltd. Aug. 1, 1940, No. 12468. Convention date, Aug. 1, 1939. [Class 108 (iii)] [Also in Group XXXV] In order to prevent vibration through the distortion of the stator of a dynamo electric machine by the field of the rotor the stator is attached to the casing by beam springs, which are practically rigid longitudinally, but flexible radially and tangentially, the radial flexibility being greater than the tangential. Fig. 2 shows an arrangement with three such sets of springs 24 secured at their ends to rings 23 on the frame by bolts 25 and at their middles by bolts 26 to bars 14 which are secured to stator. In a modification the springs are arranged only at the middle of the bars, which are directly attached at their ends to the rings 23. If the rotor is of the two-pole type the frame is so constructed that its period when vibrating with four circumferential sides is substantially different from, preferably substantially less than, half the period of rotation of the rotor.

Title: Polyolefin-coated material and method of making it
IPC: B05D1/26
Filed: 1964-03-25
Abstract: 1,030,809. Polyolefin coatings. J. H. FLYNN. March 25,1964 [Nov. 20, 1963], No. 12594/64. Headings B2B and B2E. A composite material comprising a base material and a polyolefin coating is produced by brushing the surface of the base material with flame of high heat-intensity prior to coating the surface with molten polyolefin when the temperature of the surface is below the temperature of the polyolefin coating. The surface is brushed with the flame sufficiently briefly to avoid appreciable depthwise heat penetration into the material. The polyolefin coating may be bonded directly to the base material without any other bonding agent and with the polyolefin so completely attached to the material as to show not even microscopic gapping between them substantially anywhere. The base material may be nonfibrous or fibrous, e.g. steel plate, non-fibrous plastics material, board-stock, wood veneer, closely woven textile fabrics and paper. Fibrous materials may be brushed with flame of sufficient heat intensity to incinerate loose burnable fibrous matter thereon. As shown, base material w is brushed with flame F of burner 14 as the material passes to a station A where the primed face is coated with molten polyolefin P from extruder 12. The entire face, i.e. over its whole width, of the material may be brushed with the flame. Paper may be primed by brushing the entire face thereof with a flame of temperature approximately 2500F as the paper is fed continuously to the coating station at a rate of approximately 1000 ft. per minute. The polyolefin may be polyethylene or polypropylene.

Filed: 1966-03-22
Abstract: 1,135,851. Rolling. UNITED STATES STEEL CORP. 22 March, 1966 [7 April, 1965], No. 12620/66. Heading B3M. An edge rolling mill for slabs S is positioned between a pair of horizontal roll stands A, B and comprises three pairs of vertical axes rolls 41, 42, 43 arranged to roll the edges of a hot slab fed through the mill, the rolls of each pair being spaced successively closer together. The first pair and the control pair of rolls 41, 42 are mounted between chocks 35-38 on a pair of housings 14, 14a, slidable transversally to the slab feed direction by hydraulic piston cylinder assemblies 21, 21a to vary the spacing of the rolls. The central pair of rolls 42 are spaced closer together than the rolls 41 by blocks 44 between the chocks 36, 38 and the housings. The finishing rolls 43 are mounted between chocks 39, 40 on housings 15, 15a slidable by hydraulic piston cylinder assemblies 22, 22a and have a larger radius than the rolls 41, 42 forming a narrower pass. The rolls 41-43 are tapered inwardly towards their base and have a flange 45 against which the slab S is moved as a result of the taper. The adjacent housings 14, 15 and 14a, 15a are rigidly connected together by tension bars 28. The rolls 41 and the finishing rolls 43 are driven by motors 51, 56 respectively whereas the central rolls 42 are idlers. Nozzles 61 spray the rolls with water to cool them and wipers 62 prevent the spray hitting the hot slab. The slabs are restricted against vertical movement during their passage through the mill by guides (67), (84), Fig. 1 (not shown), which extend above and below the passes between the rolls 41-43. The lower guides (67) are mounted on pedestals (66) fixed to the mill frame 10 whereas the upper guides (84) are adjustably fixed on a cross-member (71) extending between a pair of parallel beams (68), (69) connecting the roll stands A, B. The mill is readily dismantled by means of four hydraulic cylinders 24, one cylinder being connected to each of the slidable housings 14, 14a, 15, 15a. The chocks 35-40 can be detached from the frame and the rolls 41-43 from the drive motor and the chocks and rolls removed by a crane hook (86), Fig. 8 (not shown).

Title: Improvements in or relating to hydro-kinetic torque converters
Inventor: GATISS ALBERT LESLIE
IPC: F16H41/30
Filed: 1957-04-18
Abstract: 859,146. Hydraulic transmission of power. BROCKHOUSE ENGINEERING Ltd. April 8, 1958 [April 18, 1957], No. 12650/57. Class 69 (2). An hydraulic torque converter comprising impeller elements 11a, 12a, turbine elements 11b, 12b and reaction elements 11c, 12c, has an automatically controlled cooling system. Liquid flows from points 25 of the torque converter working chambers via hollow shaft 17 and piston valve 30 to cooler 34 and thence to reservoir 10. Pump 14, geared to the input shaft 13, returns the liquid through lines 38, 41 to the working chambers. Piston valve 30 is spring urged to close the passage through shaft 17 ; at low torques the pressure in lines 38, 40 from pump 14 keeps the valve 30 open. At high torques, the pressure in the working chambers rises, resulting in greater flow of liquid from points 25 to the cooler; when the pressure in the working chambers falls as a result, reduction in pressure on face 47 of valve 30 causes it partially to block shaft 17 and throttle the flow through the cooler so that the torque converter is maintained full.

Abstract: 574,799. Casting-machines. ENFIELD ROLLING MILLS, Ltd., and METZGER, O.J.. Sept. 8, 1942, No. 12674. [Class 83 (i)] A billet is formed by applying a cooled body 6 through the upper surface 2 of molten aluminium alloy or other metal and then progressively displacing the body as the metal freezes relative to a non-metallic refractory tubular mould 3, fresh metal being supplied, e.g. by a passage 4. Metal is prevented from depositing on the sides of the body 6 by insulating material. A tapered cavity 20 may be provided to ensure that the deposit moves up with the body 6 and a spring-closed clamp 12, Fig. 2, may be released by raising a camlever 18 to give additional support. Air may also be projected on to the exposed part of the deposit 16 from slots 21 of a U-shaped duct 22. In a modification, the mould walls 24, Fig. 4, defining the shape of the deposit, are attached to the cooled body 6 and move therewith. Vents 28 are provided, also insulators 32, 33 and 34, to prevent metal from depositing on the stirrup 31 &c. and sleeves 26, 27 for supporting the wall 24. The movement of the cooling body 6 is preferably slightly slower than the speed of freezing. To produce a fine grain structure, the body 6 or the molten metal may be vibrated, e.g. by an electromagnetic vibrator 29. The parts 3, 24 may be made of the material known under the Registered Trade Mark " Durex." Specification 573,433 is referred to.

Title: Improvements in time-limit dash-pots
IPC: G04F1/00
Filed: 1928-05-01
Abstract: 316,639. Erskine, A., and Jackson, A. R. H. May 1, 1928. Dashpots.-In a timelag dashpot (e.g. for operating an electric circuitbreaker), the control rod connected to the mechanism to be operated or released is provided with two or more dashpot pistons, each piston being capable of axial movement relatively to the rod, and the several pistons having retarding actions of differing magnitudes, the control rod being connected to one of the pistons in such a manner that, when the rod is actuated by moderate releasing forces, it actuates and is subjected to the retarding action of such piston, but that, when the rod is actuated by a releasing force of predetermined greater magnitude, it moves relatively to such piston, and is caused positively to engage with another piston adapted to provide a correspondingly increased retarding action, whereby the time lag for the greater releasing forces is not curtailed. As shown, the control rod B is of tubular form, and the primary or normal piston C is of bell form, and is fixed to a block c<1> slidable on the rod B and carrying a plate c<2>, which is adapted to bear against a limiting stop b<1> adjustably fixed to the rod B. The secondary or maximum piston D is fixed to a stem d<1> slidable freely in the bore of the hollow rod B. An annular passage d<5> around the piston D, for the transfer of fluid, is more restricted than that c<5> around the piston C, so that the piston D has a greater retarding action. In the case of moderate releasing forces, the piston C alone is drawn up, the force being transmitted from the rod B to the piston C through a coned sleeve b<2> and flexible struts c<3>. In the case of greater releasing forces, the struts c<3> are forced outwards by the coned part of the sleeve b<2> so as to engage an inturned flange d<4> on a ring d<3> fixed to the maximum piston D, whereby the latter is coupled to the piston C and also drawn up, the upper end of the sleeve b<2> bearing against the underside of the piston C. A port d' and ball valve E facilitate the return of the piston D to its lower position.

Abstract: 429,653. Tables &c. with folding legs. HOWE, H., One, Park Avenue, New York, U.S.A. April 27, 1934, No. 12735. [Class 52 (iii)l [See also Group XXV] In tables and similar articleswith hinged legs connected for simultaneous movement, the pivot devices are such that they can slide relatively to the table frame. The Figure shows one corner of a table 1 with a leg 5 connected to the side frame 2 by a link 17 and by a pivot sliding in a guide 16 ; there is a similar fitting at an adjacent corner, and the two legs 5 are connected by a crossbar 12. The other pair of legs is similarly mounted except that the pivots do not move in slides. These pairs of legs are connected by diametral crossing links 18, which connect the pair of legs 5, at points below the links 17, and near the pivots, to the other pair of legs at points above their pivots. If, therefore, the other legs are folded down, the pivots of the legs 5 are pushed along the guides 16, and the legs fold about their connection with the links 17. A latch 25 maintains the legs 5 in an unfolded position. In a modification both pairs of legs are mounted in guides 16.

[Class 66] [Also in Group V] A collapsable tube is made by applying one or more layers of non-metallic plastic material in a fiuid state to a mandrel 5 to provide a coating 10 over the peripheral surfaces of the body, the shoulder 6 and at least a portion of the shank 7, fitting a rigid nozzle 8 on the neck and shoulder, and applying one or more further layers 12 of plastic material to cover the previous coating and the skirt 9 of the nozzle. The plastic material may be a cellulose derivative, a synthetic or natural gum or resin or a gelatinous compound and may be applied by dipping, spraying, brushing or the use of rollers. Any or all of the layers may contain a dye or pigment so that the whole, or part, of the tube is coloured. Printed matter may be impressed upon, or a label attached to, a layer prior to the application of a subsequent layer. The nozzle 8 may be held in place by a nut 11 screwed on the shank 7 and may be secured before the coating 10 has set. Alternatively, the skirt may be coated with a cement or a solvent for the plastic material or scored to form a key with the plastic material. Specifications 504,359 and 551,151 are referred to.
