Filed: 1971-05-28
Abstract: 1310458 Tyre building apparatus GOODYEAR TIRE & RUBBER CO 28 May [1971 [6 July 1970] 18057/71 Heading B7C Tyre building apparatus comprises a number of stations A-E at which tyre components are successively applied to a plurality of drums 12 movable on conveyers 16, 50 between the stations, the tyre component applying means at each station consisting of a wheeled track 116 which is loaded with tyre stock 120 and located beneath conveyer 16, the stock from the roll 180 being fed on to an endless belt 112 on which it is cut by a mechanism 350 the cut length being then brought into adhesive engagement with a drum 12 by extending rams 315 and 335 which causes the run of belt 112 between pulleys 282 and 284 to conform to the shape of the drum by pivoting belt support 324 about pulley 280 and belt support 303 about pulley 282. After applying the length of tyre stock to a drum the belt 112 is lowered to its initial position and the drum moves on to the next station. The stock is removed from roll 180 by rewinding a liner 122 on to a roll 136 placed on a drive assembly 130 including a cradle 132 of belts 134 driven by a motor 222. The motor further drives a roller 160 around which the stock runs on to belt 112  and also a sprocket 294 used to drive the belt 112. To disengage roll 136 from the drive assembly a ram 245 engages the end 247 of arms 197 on which roll is mounted, and lifts it free of the belts 134 so that the track may then be withdrawn. The edge of the tyre stock is maintained in its correct position by actuating a ram 260 to move the track when an error is detected by a sensor 265. The cutting mechanism 350 comprises a frame 360 including an adjustable beam 362 which guides a knife carriage 370 so that knife 371 cuts the stock parallel to and between the plies thereof.

Title: Improvements in or relating to electrical resistance structures
Inventor: HOLDWAY GEORGE
IPC: H01C3/10
Filed: 1958-06-09
Abstract: 890,837. Electric resistances. FAWCETT PRESTON & CO. Ltd. June 9, 1958, No. 18336/58. Class 37. In an electrical resistor of the kind in which a length of resistive material is bent backwards and forwards between two supports, the resistive material is supported from the supporting members in the region where it bends by supports which give freedom to the resistive material to expand and contract without distorting. In the embodiment shown, a length of resistive material 1 (Fig. 1) is bent back and forth between two support rods 2 on which are mounted insulating collars 5. For attaching the resistive material to the support, a plurality of metal clips 4 are provided each in the form of a strip bent to U-shape such that it fits round the collar 5 (Fig. 2). The end portions of each clip are first bent outwards at 4a and then doubled inwards at 4b and thus form hooks which fit round the edges of the resistive material 1 to support it. When the resistive material is cool the clips fit snugly round the collars 5 as in Fig. 2, but when its length increases due to heating, the clips are pushed away from the rod 2 and take up the position shown in Fig. 4. An alternative form of the clip 4 is illustrated in Figs. 3 and 5 (not shown), in which the clips are not doubled inwards at 4b but are instead bent over at right angles. The strip of resistive material is then attached to the clip by means of a split pin which passes through holes in the clip.

Title: Improved method of and means for forming laminated cores of electrical machines
IPC: H02K15/02
Filed: 1943-12-08
Abstract: 573,421. Making dynamo-electric machines ; punching. FORD MOTOR CO., Ltd. Dec. 8, 1943, No. 18536. Convention date, Feb. 12. [Classes 83 (ii) and 83 (iv)] In making cores for electrical machines by punching holes or slots in a metal strip and then winding it up, the distances between the holes and the length thereof are progressively increased as the diameter of the wound ring increases. The end of the metal strip 23 may be secured at 28 to a former 21 which is intermittently turned through the required angle, e.g. by mechanism operated by the punch-. driving means as described in Specification 558,678. The vertically reciprocated punch head 54 has a horizontal groove G in which are mounted punch holders 61, 62 carrying respectively a rectangular punch 50, for forming a right-hand portion of a hole 53, Fig. 2, and a punch 52 mainly rectangular, but adapted to overlap the hole cut by the first punch and form the left-hand portion of the hole 53. Corresponding bolsters 56, 57 are mounted in a groove of a slide 63 which is movable horizontally by the action of the coil being wound on the former 21, the follower 33 being kept in contact therewith by a spring 32. The punches are kept in line with their bolsters by guide bars 64, 65, a spring 58 presses the holder 62 to the right, and the bolster 56 is held relative to the slide 63 by a stop 66. As the slide 63 moves to the left, it carries with it the bolsters and punches and also a slide 60 mounted to move vertically in a guide thereof and provided with a wedge portion adapted to engage between the bolsters as it is pressed down by a fixed cam 59. The bolster 57 and corresponding punch 51 are therefore moved a greater distance than the other pair so that the holes 53 produced are progressively longer as well as more widely spaced. The strip 23 may be cut finally along the line 62, Fig. 2.

Abstract: 723,461. Forging-machines. MASSEY-HARRIS CO., Ltd. July 23, 1952, No. 18595/52. In a resistance heating machine for upsetting the end of a rod against a fixed electrode head 49, Fig. 2, and in which the rod is held by a clamp 54 acting as the other electrode and which is gradually moved away from the fixed head 49, the clamp 54 and the ram 93 for upsetting the rod are actuated by double-acting hydraulic cylinders controlled by reversible valves. The fixed head 49 is mounted on screwed rod 22 which is longitudinally adjustable by collars 24, 25 in a bracket 18 attached to the bed 15 of the machine. The die mounting 39 is insulated electrically from the rod 22 by insulation 37a and is connected to a flexible lead 46 from a transformer 48. Cooling water is circulated through the mounting from flexible leads (not shown) and passages 41, 42. The clamp 54 comprises top and bottom halves 65, 59, Fig. 7, pivoted at 66 and clamped by a double-acting hydraulic cylinder 67 through links 68, 70. The clamp is supported in a slide 55 movable along the bed of the machine by a hydraulic cylinder 57 through a linkage 56. The lower half 59 of the clamp is connected to the second flexible lead 62 from the transformer 48 and bushes 75, 76 keyed within the clamp engage the work-piece and are cooled by water circulating through passages 81, 82 in the clamp body. The ram 93 is actuated by a double-acting hydraulic cylinder 88 through a slide 102, the ram being guided in bushings through a bracket 95 mounted on the machine bed. The hydraulic supply for the cylinders is obtained from a pump 113 and in operation the cylinder 67 for the clamp and the cylinder 88 for the ram 93 are simultaneously actuated by a hand lever 108 (not shown) controlling a single valve coupled to both cylinders. An adjustable flow regulator and check valve prevent actuation of the cylinder 88 until the work is clamped. The transformer is operated by a push-button and the current flow preset by a switch 111. After the required amount of upsetting the ram cylinder 88 is automatically reversed, the clamp 54 released and the current supply cut off by the engagement of an arm 105 (not shown) on the slide 102 which engages an adjustable stop on the machine bed. During the upsetting operation the cylinder 57 is actuated to move the clamp 54 away from the die 49 at variable rates by a control lever 127 (not shown).

Title: Improvements in computing devices
IPC: G06G7/163
Filed: 1962-05-16
Abstract: 1,001,893. Electric analogue calculating. BAILEY METER CO. May 16, 1962, No. 18936/62. Heading G4G. In a computing device comprising a highgain D.C. feed-back amplifier having passive impedances in the input and feedback circuits, from which amplifier an output is obtained which is a function of two variables, one represented by the value of an input signal applied to the amplifier input circuit, the other represented by the value of the passive impedance in the input circuit, the variable value impedance in the input circuit is provided by an arrangement for cyclically alternately connecting into the input circuit one half and the other half of a transformer primary winding, an A.C. impedance in the circuit of the transformer secondary winding and arrangements for varying the value of the A.C. impedance. The output voltage e 0  of an operational feedback amplifier is given by where Z f  and Z 1  are the passive input and feedback impedances and e 1  is the input voltage. Thus if Z f  is kept constant and Z 1  and e 1  varied as functions of some quantities, an output is obtained which is a function of both variable quantities. A feed-back amplifier 12 is supplied with a variable input signal e 1  through a resistance input circuit 20. In this circuit a chopper 36 vibrating at the frequency of the supply 42 maintains a D.C. path for the input signal to the amplifier either through the contact 42 and the transformer winding 28a or through the contact 34 and the winding 28b. The effect of the chopper, however, is to produce an alternating square wave signal across the primary winding 28 of the transformer 24. The second variable signal e 2  varies the D.C. bias on the transistor 46 (energized from the D.C. source 52) and thus the A.C. circuit resistance of the transistor to the alternating signal induced in the secondary winding 26 of the transformer. This is reflected into the primary winding 28, so that a variable A.C. resistance is established, proportional to the input e 2 , this resistance being the passive input impedance of the amplifier. Thus Z 1  is proportional to e 2 , and the feed-back amplifier will supply an output voltage proportional to e 1 /e 2 .

Title: Process for purifying and crystallising metals or non-metals or compounds or alloys thereof
IPC: C30B11/10
Filed: 1959-06-03
Abstract: Impurities are vaporized from a substance by <PICT:0926515/III/1> transferring molten drops of the substance in succession on to a rod or tube of the substance and progressively crystallizing the molten substance on to the rod or tube at a pressure of 10-1 to 10-7 m.m. of mercury.  Substances specified are titanium, stainless steel, and sodium chloride.  Heating may be by electric induction, ion or electron bombardment, infra red radiation, or hot gas.  Induction heating means may be cooled by water or compressed air.  The substance may be crystallized in mono- or polycrystalline form.  The drops may be transferred from one rod or tube which is progressively melted to another which is correspondingly built up, and the process may be repeated by reversing the positions of the rods or tubes. Drops may be passed between rods of dissimilar dimensions.  An inert gas may be passed through a tube to prevent blockage thereof. Instead of melting a rod, substance in the form of particles or wire may be added to a drop at the end of a rod which is maintained constant in length. Instead of adding the substance itself in the case of a compound or alloy the starting materials for the production thereof may each be added to the drop.  Transfer may be aided by applying electrical tension or mechanical vibration.  Premature transfer may be prevented by the use of an electromagnetic field. Alternatively a current of inert gas may be passed over the drops. As shown a drop 4 maintained molten by means of an induction coil 3 is transferred from a magnetically suspended rod 2 to a lower rod 2a by lowering the rod 2, and is maintained molten thereon for a brief period by means of an induction coil 3a.  Crystallization of the drop on to the rod 2a is effected by lowering the rod 2a.

Title: Improved manufacture of aldol from acetaldehyde
IPC: C07C45/72
Filed: 1920-07-07
Abstract: Aldol is prepared from acetaldehyde by first neutralizing the acetic acid content thereof and then treating with an alkaline condensing agent not dissolved in an organic solvent.  The neutralization may be effected by means of aqueous alkali, and the condensation by solid, dissolved, or suspended caustic alkali, alkaline earth oxides, hydroxides, cyanides, carbides, &c. The reaction is preferably carried out in an atmosphere of inert gas such as nitrogen, to prevent oxidation of the aldehyde to acetic acid.  The presence of water facilitates the reaction, particularly when using alkaline-earth carbides as condensing agents.  The heat of reaction is removed by cooling, and the alkaline condensing-agent is finally neutralized by adding acid.  The Specification as open to inspection under Sect. 91 (3) (a) states that, instead of neutralizing the acid present in the aldehyde, it may be first freed from acid by distillation over lime.  This subject-matter does not appear in the Specification as accepted.
