Title: Improvements in and relating to means for measuring, indicating and recording fluid pressures
IPC: G01L7/00
Filed: 1931-07-09
Abstract: 380,627. Elastic diaphragm pressure gauges. JEFFCOTT, H. H., Storth Holme, Ashley Park Road, Waltonon- Thames. July 9, 1931, No. 28778. Divided application. [Class 106 (ii).] Comprises an elastic diaphragm connected to a part or parts of a magnetic circuit or circuits containing a variable gap or gaps, the circuit or circuits being arranged as a transformer or transformers fixed relatively one to the other and connected to electrical instruments. The diaphragm 1 is of steel and fixed to a brass cylinder 9 screwed into the cylinder wall or even into the piston of an engine. Attached to the diaphragm is a piece 4 of iron or high permeability metal making up with parts 5, 6 of like metal and the gap 3 the magnetic circuit. A coil 7 carries the magnetizing current and the movement of the diaphragm under the pressure changes in the cylinder causes changes in the flux through the secondary coil 8 which is connected to the measuring instrument. In a modification the part 4 is not hollow and the parts 4, 5 around the gap or gaps 3 are differently shaped. The apparatus is calibrated by the application of known pressures. The records may be made on a time or stroke base by a suitable operation of the record drum. By suitably interposing in the electrical circuit a sliding contact in which a brush 10 is moved to and fro by a connection from the piston along the copper bar 11 which carries slots 12 of suitable widths filled with insulating material, records of the current at a series of points throughout the stroke may be obtained. A rotating commutator could be similarly used.

IPC: B65B13/02
Filed: 1938-10-04
Abstract: 519,813. Strapping-machines. SIGNODE, Ltd. (Signode Steel Strapping Co.). Oct. 4, 1938, No. 28794. [Class 45] A tensioning tool for a flexible binder comprises a gripper movable to an open position to receive and to release the binder, and to a closed position to anchor an end of the binder, and tensioning-mechanism for pulling on the other end of the binder and operable relatively to open the gripper. The tensioning device, which may be similar to that described in U.S.A. Specification 1,912,045, comprises a slotted windlass 12, Fig. 5, upon a shaft 16, Fig. 4, adapted to be rotated by the oscillation of a handle 13 having a spring- pressed pawl 14 acting upon a ratchet 15. A pawl 17 . prevents retrogression while the handle is being moved clockwise. Each pawl is associated with a pivoted control lever 18, 19 with camshaped projections 21, 22 arranged so that, when the handle 13 is moved to an extreme position as shown in Fig. 5, the projections co-act to withdraw both pawls to release the windlass for free rotation. The gripping device for the other end of the band is similar to that described in Specification 409,168 and comprises a wedge-shaped block 25 housed in a mounting block 26 on an eccentric 28. The eccentric shaft 29 is operated by a lever 30 biassed in an anticlockwise direction by a spring 35 surrounding a plunger rod 36 passing through a pivoted guide 38. In use, one end of the band is placed in the slotted windlass and the other beneath the gripping block 25. The handle 13 is oscillated until the desired tension is reached, and is then pressed down into the position shown in Fig. 5 after a joint has been made. The parts 21, 22 co-act to release the windlass, and a lug 47, projecting from the handle, engages a surface 46 on an extension 45 of the lever 30, rotates the eccentric 28 in a clockwise direction and lifts the gripping block 25 into an open position. The lug passes into a recess 48, which has a latching effect to detachably hold the parts in the position shown, in which position the whole device may be disengaged from the band. The lever 30 may be rotated further by means of its extension 45 so that the pivot 37 passes a dead centre and the gripper is thus retained open independently of the handle 13.

Abstract: 320,519. Coulter, W., and Wood, H. F. Oct. 8, 1928. Moulding hollowware; moulds; pressing- dics.-Tea-pots &c. are formed from clay dust in halves and the halves are brought together and united by pressure dies. As shown, clay dust is pressed within a lower mould by an upper die g fitting within a shouldered portion of the mould. A lower ejecting plunger j is so dimensioned as to determine, when raised, the proper quantity of dust. The parts are shaped to form one half of the body h, rim h<1>, pout and handle. A transverse hemicylindrical die i is advanced by mechanism actuated by the upper die, against the action of a spring i<1>, to form the base. The die g is fitted with a spring-backed panel i' to ensure proper register of the dies. Left and right-hand die parts are employed and the two halves, after pressing, are brought together between press moulds k, Fig. 7, after moistening the edges with slip. Plungers l, m, engaging the rim h<1> and base h' respectively, sustain the article against pressure by the moulds which are formed with knife edges to ensure a clean junction. The upper mould may be furnished with a spring-loaded panel k<1> to deliver the article on to the lower mould. A slip reservoir may surround the lower mould. The pressing of each half pot may be effected upon a rotary table.

Title: Electromagnetic contactor
Inventor: SCHROEDER CHARLES SCHOERN
IPC: H01H50/64
Filed: 1954-10-07
Abstract: 759,986. Electromagnetic switches. YALE & TOWNE MANUFACTURING CO. Oct. 7, 1954, No. 28896/54. Class 38(5) An armature 11 pivoted on an edge 15 on a bracket 13 and biased to the open position by a spring 20 acting between a lug 19 on a horizontal arm 18 of the bracket and an arm 16 of the armature extending through a bracket slot 17, carries a knife edge member 27 having edge parts 28, 29 co-operating with grooves 30, 31 in a contact arm 10, a centre part 32 of the member 27 extending through a slot 33 in the arm. A stud 34 on the armature extends freely through an opening 35 in the arm 10 and is surrounded by a spring 36 acting between the upper surface of the arm and a washer 37 on the end of the stud. When the contactor coil 12 is energized a contact 24 attached to the arm 10 engages a fixed contact 21, the spring 36 yielding upon contact engagement to permit further movement of the armature, Fig. 2, this further movement producing a wiping of the contact surfaces. The widely spaced bearing surfaces 30, 31 of the contact arm and the pressure of the spring 36 prevent a " cocking " movement of the arm when the contacts engage to accommodate any misalignment between the contact surfaces. Consequently, the contacts are caused to wear until they make good surface engagement, the wear then becoming very slow.

Title: Improvements in multiple-contact switches and relays
IPC: H01H50/56
Filed: 1946-09-27
Abstract: 617,372. Electromagnetic relays. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Sept. 27, 1946, No. 28909. Convention date, April 21, 1943. [Class 38 (v)] A multiple-spring contact relay having two side-by-side banks of contacts, has a ladder-like actuating-member having a central metal rod 3 secured in an insulating part 4 of a cross-arm 5. Distance pieces 18 and a number of insulating transverse arms 12 are placed on the rod 3. Movable contact springs, as 13, 14, bear on the arms 12 and on frangible projections 10, 11 of the arm 5, a complete assembly being shown in Fig. 2. The projections 6, 7 on the arm 5 engage in recesses 8, 9 in the armature of the relay. Rocking movement of the actuating- member, as indicated by arrows.P, is prevented by fixing the top cross-arm to the top contact springs. The apertures in the transverse arms may have projections 33, 34 so as to support the arm on the rod 3 in spaced relation at 35, 36 with the arm along the axis of the latter, thereby increasing the leakage path.

Title: Improvements in or relating to bobbin or spool winding machines
IPC: B65H54/04
Filed: 1930-09-27
Abstract: 357,786. Winding wire, rope, thread, &c. LARMUTH & BULMER, Ltd., Todleben Iron Works, Unwin Street, Salford, Manchester, and HUGHES, T. C., 2, Oxnam Crescent, Newcastle-on-Tyne. Sept. 27, 1930, No. 28958. [Class 120 (ii).] The traverse mechanism of a machine for winding wire, thread, cord, rope, &c. on bobbins or spools comprises a shaft 6 on which are a loose driven gear 7 and a fast gear 10, Fig. 1, both in mesh with a pinion 13, Fig. 3, which rotates about its own axis, or revolves about the shaft axis, the rotation of the pinion 13 being prevented or permitted automatically or at will to cause the shaft 6 to rotate in one or the other direction whilst the loose gear 7 is driven constantly in the same direction. A belt drive with fast and loose pulleys 37, 38 rotates the bobbin 1 through a slot and projection coupling 32, and, through change speed wheels 40, 41, 42, a gear 9 compounded with the bevel gear 7. A disc 11 between the bevels 7, 10 carries the bevel pinion 13 on a radial stud 14 in a gap 12 in its periphery, a block 16 with a locking tooth 18 meshing with the pinion 13 being mounted on a ring 15 which is secured to the disc 11 by screws 20 through slots 21 which allow limited relative circumferential movement between the ring and the disc, a spring 24 tending to maintain engagement of the tooth 18 thus locking the bevel 13 and rotating the bevel 10 with the bevel 7 and moving the traverse carriage 4 which has a nut 8 engaging a thread 5 on the shaft 6. At the ends of the traverse, stops 43, 44 adjustable on a rod 31 are engaged causing an abutment on a tumbler lever to be brought into and out of engagement with stops 25 on the ring 15. The abutment arrests the ring 15 and therefore also the disc 11 with the tooth 18 out of engagement with the pinion 13, thus causing the shaft 6 to be rotated in the reverse direction, and the traverse carriage to be reversed. The rod 31 may be retained in the end positions by a spring plunger &c. The material being wound passes over pulleys 46, 47, 48, Fig. 1, the pulley 47 being weighted by a sliding block 51 carrying a roller 52 which on excessive tension moves a lever 53 fulcrumed at 54 and connected by a link 55 &c. to the belt-fork 39 which may also be operated by a hand-lever 56.

Title: Production of a coloured pile surfaced products
IPC: D04H11/00
Filed: 1971-06-21
Abstract: 1399095 Pigmenting and tack-spinning; pile fabrics IMPERIAL CHEMICAL INDUSTRIES Ltd 14 June 1972 [21 June 1971 9 Aug 1971] 28958/71 and 37294/71 Headings D1B and D1K A pile-surfaced product in which the pile is formed by a tack-spinning process is pigmented by applying pigment to a component of the laminate to be subjected to tack spinning before the pile is formed. The pigment may be applied to a web component of the laminate in such a way that it is carried into the pile during pile formation and/or it may be applied to the polymeric component of the laminate which subsequently comprises the pile. The pigment may be distributed evenly or its distribution may be discontinuous. When it is the web that is pigmented the pigment may be applied to the web immediately before the web contacts the polymeric material, and this may be effected on the same apparatus as that in which pile formation occurs just before the pile forming step. The pigment applied to the web may 'be soluble in the polymeric material, or any component, including solvent, of the polymer composition, employed in pile formation. Where the pigment is insoluble in the polymer component and is carried into the fibres from the web by flow currents in a mechanical fashion the only requirement is that the pigment should be particulate so that it may be so carried and that it be sufficiently loosely adhered to the web that it may be dislodged from it and carried into the pile under the pile driving conditions employed. It may be desirable to apply pigment to the web in the presence of a bonding agent which may enhance its adhesion to the web but which, under the pile driving conditions employed, releases the pigment into the polymeric pile-forming material. A preferred method of applying pigment to the laminate is by a transfer printing process, optionally while the polymeric material is in contact with the temporary anchorage surface used to form the pile in the tack-spinning process. Dyestuffs particularly suitable for this application are volatilisable disperse dyes. In examples polyethylene pile is coloured with 2-hydroxy-5- methyl-4'-acetylaminoazobenzene; 1, 4-diamino-2-methoxy-anthraquinone; 1-hydroxy-4-(ptoluidino)-anthraquinone; carbon black; and other unspecified colourants. Five figures illustrate in diagrammatic sectional elevation different types of apparatus suitable for effecting the process using disperse dyes. British Specifications 1334672; 1378638; 1378639 and 1378640 are referred to.

Title: Improvements in and relating to the generation of ion beams
IPC: H01J49/14
Filed: 1967-06-23
Abstract: 1,141,447. Ion sources. BALZERS PATENTUND BETEILIGUNGS. A.G. 23 June, 1967 [1 June, 1967], No. 28996/67. Heading H1D. A method of generating ions by bombarding a solid body with a beam of charged particles, preferably electrons, is characterized in that the incident beam is of such intensity as to penetrate into the body and form therein a channel filled with plasma from which the ions are extracted by an electric field. The ions may be extracted from the side of the body impinged on by the incident beam, or from the opposite side if the body is thin enough for the plasma channel to extend through it. The method may result in a high yield ratio of output ions to input electrons and may provide the ion source for particle accelerators, isotope separators or for coating materials with extremely pure thin layers.

Title: Improvements in toys and race games
IPC: A63F9/14
Filed: 1955-10-13
Abstract: 828,157. Travelling toys for race games. BASCOMBE, H. J. Jan. 11, 1957 [Oct. 13, 1955; Feb. 15, 1956], Nos. 29124/55 and 4686/56. Classes 132(2) and 132(3) A toy of the kind which moves down an inclined surface in a step-by-step rocking movement comprises an inverted box-like member 11 which forms a rocker member and which has suspended in it a pendulum leg 17 arranged so that when it swings to either of its end positions against walls 13, the foot 19 passes above the arcuate underfaoe 12 of the rocker member. A representation of a horse and rider is detachably mounted on a pair of posts 47 provided on the top of the rocker member, and the rider may be detachable from the horse. In forming a race game, a plurality of the toys may be employed with a track consisting of a number of sections joined end to end and supported on two frames 26. A starting device 29 comprises a frame 32 pivoted to vertical extensions 30 of the end support frame 26 and is operated by a solenoid 37 energizable by batteries through a switch 40. In using the device, Fig. 5, each figure is rested on the forward bar 34 of the pivoted frame 32, operation cf the solenoid causing the bar to be raised and allowing the toys to rock forwardly to commence their step-by-step movement down separate channels 25. Such movement results from the leg 17 swinging forwardly as the toy rocks forwardly, the foot 19 projecting below the underface 12 and contacting the inclined track surface to cause the toy to take a step forward. The leg then swings rearwardly and its foot moves level with the underface 12 allowing the toy to continue its forward rocking motion for a small distance before commencing a rearward rocking movement. This rearward movement continues to such an extent as to allow the leg to swing forwardly and vertically, ready for the next step when the toy rocks forwardly. To indicate in what order the toys finish, indicator lamps 43 are operated by switches 44, the contacts of each switch being closed by pressure of a toy as it reaches the end of the track. The rocking characteristics of each toy may be varied by using different rider members or by providing a pendulous member which may comprise an arm or a pair of arms or the head of the rider. The pendulous member may have adjustable balance means. A spring for engaging the track and extending below the underface 12 may be provided at one or both ends of the rocker member to assist the rocking movement of the toy.

Abstract: 427,636. Husking &c. cereals &c. HELLER, J., 140, Wõhringerstrasse, Vienna. Oct. 21, 1933, No. 29239. Convention date, Oct. 26, 1932. [Class 58] In a machine for polishing and husking cereals and legumes of the type provided with an adjustable grinding or polishing member and with a number of husking channels, through which the kernels pass and separated by air channels, the channels being formed by U-shaped bars or their equivalent the bars are adjustable towards or from the grinding surface and each husking channel has a pressure member consisting of a number of independent resilient sections. In the form shown U-shaped bars 8 are carried on discs 5, 6, mounted on a shaft 2 which rotates in bearings in a conical casing. Grains are fed into the casing from a hopper 10 and pass through a cap 3 into the channels of the bars 8 down which they pass while being abraded by a grinding surface 1. The distance between the bars and the grinding surface may be adjusted by moving the bars along the axis of the shaft. One side wall of each channel bar is longer than the other to direct the grain into the channel. The grains are pressed against the surface 1 by a number of U-shaped springs 9 arranged in each channel one arm of each spring being secured to the bottom of the channel. The operating face of the springs may be waved. The bars are separated by air passages through which air is drawn by connections to a suction channel 12. The conical casing may taper in the same way as or in the opposite way to the direction of movement of the grains. In modifications the grinding member and the bar drum rotate in opposite directions and the bars may in addition to their axial adjustment be arranged to be radially adjustable in concentric grooves. The pressure members 9 are carried by an outer frame and extend into channels between the bars the grinding member being arranged as a conical drum inside the bar drum; the frame carrying the pressure members is adjustable by a screw shaft and hand wheel; valves control the suction ; the drums may be vertical instead of horizontal. In a further modification the grains are fed into the centre of a space between an horizontal grinding disc and substantially radially extending bars thereabove, pressure members consisting of a number of resiliently mounted blocks being arranged in the channel between each pair of bars. The bars can be turned end for end or upside down when wear takes place. Specification 299,312, [Class 58], is referred to.
