Filed: 1929-08-27
Abstract: 328,890. I. G. Farbenindustrie Akt.-Ges. Oct. 3, 1928, [Convention date]. Tubes; rods and bars. - A metal strip e.g. of magnesium or its alloys is fed in between dies a, b, the top die having a repeated stamping action, and the pass section of the dies varying gradually from flat strip to the finished shape at A-A; Fig. 2 showing the gradual shaping of the metal in successive small steps. To make closed tube &c. sections, e.g. Fig. 5, or partially closed sections, dies a, b, Fig. 6 partly form the section and then a pair of side dies i oscillating about pivots l force the metal around the mandrel k, step by step, as it issues from the first dies. In Fig. 7 a Z- section is formed with a split mandrel k<1>, k<2> both parts of which are fixed to the base m. In Fig. 8 the section - coming from the dies is curved by an adjustabte block c or the dies themselves may be shaped to curve the section. In Fig. 10, stepped profile rings are made from flat strips, the upper die a - stamping the strip against the die b<2> as strip is fed in to profile it gradually, and the strip is then curved by the action of the same top die a against the 2-part rotatable drumlike die b' around which the strip coils itself to form a complete ring. The drum die b' is then split apart to allow the ring to be taken off.

Abstract: 425,905. Glazing fruit. BRAMIGK & CO., Ltd., 15, Creechurch Lane, London. Sept. 20, 1933, No. 25984. [Class 28 (i)] In the glazing of fruits, the fruits previously treated with sugar, e.g. by the process described in Specification 397,196, are placed in a concentrated sugar solution in a steamjacketed pan, the fruit being held in a basket e and the temperature of the solution being maintained for a suitable period. The basket e is then removed to a jacketed glazing-pan g containing a concentrated glazing solution. Steam is added to the jacket by the pipe i, to heat the solution prior to the introduction of the fruit. The steam supply is then cut off, and cold water is admitted to the jacket, at h<1>, a jacket drain for the cold water or condensed steam being provided. Wipers k are oscillated to throw the solution against the walls of the pan on which it is cooled, the grained or granulated sugar thus formed tending to fall to the bottom of the pan g. The agitators 9, however, keep the grained sugar circulating around and between the fruits. The agitators 9 are carried on a rotary shaft 10 driven through bevel gearing 11 from the motor shaft u. A worm on the shaft u drives a worm-wheel w on a shaft x which carries a crank disc y having a roller z engaging in a slot 2 in an arm 3 extending from a quadrant 4 pivoted at 4<1>. The quadrant 4 meshes with a pinion 5 secured to a bevel quadrant 7 meshing with bevel teeth on a disc q having upstanding arms m which carry the wipers k. The arms m are embraced by a ring n, being secured thereto by screws n<1> which are shaped at their ends to receive balls o which bear on a ring p on the pan g.

Abstract: 1,236,693. Feeding sheets. HITACHI Ltd. 21 May, 1969 [24 May, 1968], No. 26040/69. Heading B8R. Sheets 23 piled on edge are separated in turn by a perforated suction belt 17 when permitted by a retaining finger 29 and fed between the belt 17 and a reversely moving belt 36 which rectifies double feed, and thence to a further belt 39, passing photoelectric detectors 41-44. When a sheet reaches the detector 41, the finger 29 moves to stop separation of the next sheet, the finger allowing separation when the sheet has passed the detector. For continuous sheet feed, when a sheet reaches the detector 43, then if a preceding sheet is still present at the detector 44, a clutch is opened to stop the belt 17 until the preceding sheet has cleared the detector 44, when the clutch is re-opened. For on-demand feed, every sheet is stopped when it reaches the detector 43 until the clutch is closed by an external feed signal. To avoid prevention of feeding of a sheet when said sheet is stopped with its leading edge past the detector 41 when the preceding sheet at the detector 43 stops the belt 17, so that when the belt re-starts the finger 29 is still in its stop position, the detector 42 is provided, which releases the finger as soon as the preceding sheet has cleared the detector 42.

Abstract: 278,388. British Thomson-Houston Co., Ltd., (Assignees of Langmuir, I.). Oct. 2, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Thermionic valve circuits.-In apparatus for measuring small intervals of time, particularly applicable to the determination of depths and distances by means of reflected waves of sound, a rotating pointer 29 carries a neon tube which is caused to flash when the impulses from a transmitting device 1 are received by a microphone 4 or the like. The pointer 29 is rotated at a constant speed by a motor, and, when in the vertical position, is adapted by means of a contact 35 and a slip ring 36 to close relay 3 so as to energize the transmitting device 1. The impulses are reflected from the ocean bed 37 to the receiver 4, and are applied through a transformer 11<1> to the grid circuit of an amplifier 5, which is coupled by a transformer 16 to a vapour electric tube 6. The change in grid potential renders the tube 6 conductive, and so allows a condenser 25 to discharge The condenser is energized from a sources 7 and the resulting discharge current, acting through a transformer 24 and slip rings 32, 33, '' flashes " the neon lamp on the pointer 29. The distance which the pointer 29 has rotated from its vertical position when the flash appears determines the depth of the water, this depth being indicated on a scale 28. To measure the time an impulse takes to travel from the device 4 to a given point, a, second receiving device located at that point is connected to a transformer 16<1> through an amplifier similar to 5. An impulse emitted from a transmitter close to the device 4 is immediately received thereby, and after a certain interval is received by the second receiver, the time interval being indicated by the successive flashes of the neon tube, as the pointer 29 travels over the scale 28.

Abstract: 1294796 Making wirework WEHRLEWERK AG 19 April 1971 [21 Feb 1970 (2) 26 March 1970] 26139/71 Heading B3A An apparatus for producing a cylindrical cage with a ball-shaped end comprises an axially displaceable disc 3 that pulls longitudinally extending wires 8 in cylindrical array through a non-axially displaceable disc 2, a wire 14 that is wound helically around the cylindrical array of wires 8, a welding device 30 that unites wire 14 with the wires 8, and means 10, 12; 13 for adjusting the radial setting of the wires passing through the non-axially displaceable disc 2. The discs 2, 3 rotate to permit the wire 14 to be wound helically about the assembly of wires 8. The disc 3 is carried by a pedestal L that moves in the direction P to draw the wires 8 out of magazines 11 and through radially adjustable guides 10 carried by the disc 2. When a cam surface 28, carried by the pedestal L, acts on a roller 27 the resulting upward movement of the roller 27 acts through a linkage assembly to move a disc 13 from the setting shown in solid lines to the setting shown in broken lines. This movement of the disc 13 causes arms 12 thereon to push the guides 10 radially outward to provide the cage with the aforesaid ballshaped end. The inclination of the magazines 11 is adjustable.  Fig. 3 (not shown) illustrates how movement of the roller 27 by the cam surface 28 also moves the welding means radially to allow for the increased diameter of the cage at this stage. Fig. 2 (not shown) shows how the welding device arranged for resistance welding consists of two coaxial welding rollers of which only the front roller (40) is shown). The rear roller contacts the bar 8 to be welded and the front roller (40) effects the actual welding between the wire 14 and the bar 8. The rollers are connected to a transformer (42) and dip into water containers (46) supplied with cooling water via conduits (47).

Abstract: 649,553. Friction clutches and couplings. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Oct. 12, 1948, No. 26561. Convention date, Oct. 31, 1947. '[Class 80(ii)] [Also in Group XXXIV] A clutch or a coupling has two closely spaced movable elements of magnetic material between which magnetic particles, preferably in a fluid, are maintained and, when a magnetic field is applied, locking of the said two elements is effected. Fig. 1 shows a driving shaft 1 having a disc 3 secured to it, and a driven shaft 2 having fixed to it a cup 4 containing a fluid, e.g. oil in which iron dust is placed. When a coil 6 is energized from a source such as a battery 7 magnetic flux flows as indicated by the arrows and a magnetic locking of the elements 3, 4 is effected through the medium of the iron dust contained there between. The locking torque can be made variable by the use of a variable resistance 9. If either of the shafts 1, -2 is held stationary the device can be used as a brake on the application of the magnetic field. In a modification, the two elements 3, 4 of the device are replaced by two cylindrical magnetic bodies with the exciting coil mounted concentrically within the inner element. This coil can be eliminated by making the inner element of permanently magnetizable material strongly polarized at spaced areas around its periphery but in this form the torque cannot be varied unless a still further modification is made consisting in making the two elements of the device conical and means provided to alter the air gap between them by moving axially the inner element Fig. 4 (not shown). In a further modification, the device is made particularly useful as a brake by employing a number of discs fixed to each of the two elements of the device and by providing a circulating cooling system to dissipate the heat. In another modification. the exciting coil is held stationary and positioned concentrically outside the outer of the two elements. When used for A.C. the two elements are laminated and the A.C. exciting coil is mounted either on the inner or on the outer element.

Abstract: 444,486. Knitting. JONES, T. H., The Aspens, Breck Hill Road, Woodthorpe, Notting- hamshire. Sept. 18, 1934, No. 26779. [Class 74 (ii)] An anti-ladder fabric has one or more thread loops, each of which is spread over at least two needle wales, and, in at least one of the wales, extends through a needleloop of the same course, and itself continues on to form a needle loop. In the production of the fabric on a circular latch-needle machine, a needle 24 is raised so that its stitch 40F, is distended by a projection 25 on the needle. A shorter adjacent needle 24<1>, actuated by a separate cam race, is projected through the distended loop, but not high enough to clear the loop 40F below its latch. The needle 241 then descends, drawing through its own loop 40G, a loop 40fg from the loop 40F. Both needles are then raised to feeding position, and draw new loops. In the resultant fabric the loop 40F is passed through the loop 40G, and, continued on to form a loop 40fg. In the next course the loop 41G is drawn through this loop 40fg.instead of through the loop 40G, and is itself spread sideways, passed through the loop 41H and continued on to form a loop 41gh of a succeeding course. In any one course the loops may be spread, say from each odd needle over the next even needle and in the next course embodying spread loops, they may be spread from odd to even needles in the same or opposite direction, or from even to odd needles. Plain courses may be interposed between courses incorporating spread stitches so that spread loops alternate with ordinary loops along each course and wale. The spread stitches may be grouped to form patterned areas. Any suitable known instruments may be used to spread the loops. The Provisional Specification describes the production of the fabric on a cotton type bearded needle machine, using points for spreading the loops.
