Title: Vehicle supported winch
IPC: B66D1/14
Filed: 1976-07-21
Abstract: 1506997 Controlling winches CATERPILLAR TRACTOR CO 21 July 1976 [15 Dec 1975] 30432/76 Heading B8B A vehicle mounted winch drum 12 is driven by a power take-off 22 from the vehicle, the drive from the input 22 passing through a normally disengaged input clutch 34, gearing 38, 42 associated with a normally engaged brake 44 and an output shaft 62 coupled to the drum 12 through a normally engaged disconnect clutch 64, the clutch 34 being engaged, and the brake 44 and clutch 64 being disengaged, by fluid pressure in a circuit including a pump 68 and a fluid accumulator. In a Brake-On mode, the input clutch 34 is disengaged, the brake 44 is engaged and the disconnector clutch 64 is engaged whereby the winch drum 12 is locked. In a Reel-In mode, only the input clutch 34 is pressurized for engagement, the disconnect clutch 64 and brake 44 remaining unpressurized for engagement, but a one-way sprag clutch 41 permits the brake 44 to be overridden in the reel-in direction, whereby the drum 12 winds in cable 14. In a Brake-Off mode, only the brake 44 is pressurized for disengagement. The pump 68, driven from the input transmission for the drum, changes the accumulator when necessary and continuously supplies fluid to lubricate the winch, the accumulator supplying the operating pressure fluid. The mode of operation is normally selected by a spool valve which includes a strong spring pressure which has to be overcome when the Brake-Off mode is selected, further movement of the spool once the brake 44 has been released, causes pressurization of the disconnect clutch 64 to disengage the same.

IPC: B21D15/06
Filed: 1924-12-18
Abstract: 237,797. Kossowski, W. Dec. 18, 1924. Corrugating. - In making corrugated metal tubes by applying axial pressure to a tube heated in zones, an annular wall of air is produced between the last-formed corrugation and the zone which is being heated. The tube 1 is surrounded by a two part furnace 3 provided with a series of gas jets 2 and mounted on a slide 7. An air chamber 4 is provided on the side of the furnace adjacent the last-formed corrugation b, supplied with air from the same source as the gas jets and having an exit slot 5 so as to form a wall of air between the zone a and the corrugation b and so shield this corrugation from the heating jets. By the use of a single air supply should the supply fail the gas jets are extinguished and damage to the tube is avoided. The tube is continuously rotated during heating.

Filed: 1952-12-02
Abstract: 737,801. Digital electric calculating apparatus ; statistical apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 26, 1953 [Dec. 2, 1952], No. 30517/52. Class 106 (1). [Also in Group XL (b)] Apparatus for reading information from a punched or similarly marked member, comprises means for moving the member, means for sweeping a beam of light in a direction opposite to the direction of motion of the member, and a light-sensitive device for receiving light passing through punched holes or similar lighttransmitting indications in the member whereby electrical pulses representing the information recorded on the member are generated. Digital information is recorded in a tape 1, Fig. 1, by punched holes spaced along its length, the tape being fed towards the left by a winch 4. Mirrors 12 and 14 moved by electromagnets 15 and 16, respectively, cause a beam of light from a source 10 to be scanned along the tape in a direction opposite to the movement of the tape. This gives rise to a series of signals at a photocell 9 which represent input data for a digital computor. In addition to this data, further indications on the tape which control the feeding winch 4 are picked up by another photocell 20. More than one line of holes may be punched in the tape and several items of digital information may be read by a row of photo-cells simultaneously. In another embodiment (Fig. 2, not shown), a rotating polygonal mirror drum is used to scan the light beam along the record tape, and a third photo-cell is used to pick up an initiating signal. This signal is used to gate the result of the next complete scan into the computor. In a third embodiment the light source 10, Fig. 4, is located within a transparent cylinder 32 over which the data tape is passed. A slotted drum 34, rotating in a direction opposite to the motion of the tape, provides for the scanning action, signals being picked up by photo-cells 9, 20 and 24, as before. All embodiments may be modified to deal with punched cards instead of punched tape. Specification 717,114 is referred to.

[Class 17 (i).] Sole blanks, machines for.-A machine for marking a sole to indicate to an operator where an operation should begin or'end comprises a work-support, means for positioning a work piece on the support, and a tool movable towards the workpiece to mark an ink line on the margin at opposite sides. A rotatable inking roll is moved into engagement with the tool during operation of the machine and is rotated step by step during successive operations. The inking roll is readily removable. A pulley 6 drives an eccentric 10 by a one-revolution clutch, the eccentric being linked to a lever pivoted at 20 and comprising a pair of spaced arms 16 resiliently carrying an inking blade 22. The blade is guided by slots engaging screws 26 and is backed by springs 28. Each arm 16 is linked to a lever 72 pivoted at 76 and slotted at its end to admit a reduced portion of the spindle 90 of the inking roller. A recess adjacent the slot is engaged by a boss 94 to retain the roller in position, the boss being backed by a spring 100 which is compressed when it is desired to exchange the roller. A toe-gauge 50 is carried by a slide 46 marked with graduations reading against an edge 65 and clamped by a screw 48. A pair of side pins 42 on each side of the work support 30 are adjustable towards and from each other by a head 36 turning a right-and-left-hand screw. One of the pins is formed with a flat to read against a scale 64. A guard 68 of safety glass prevents the operator's fingers from getting under the marking tool. When the rear end of the sole is to be marked, a V-shaped heel end gauge is positioned at the rear end of the slide 46. The upper surface of the table is marked with a line corresponding to the operative position of the tool 22. In operation, a sole is placed on the table, positioned in respect of this line and the toe and side gauges moved up to the work. A sole for a right shoe engaging the right-hand front pin 42 and the left-hand rear pin, that for a left shoe engages the other pair. The clutch is engaged when the tool rises slightly and the links 80 pull the inking roll into contact with the marking edge, a pawl 82 giving the roll a slight turn by engagement with a ratchet wheel 84 immediately prior to the contact. The tool then descends, marking the ball, and subsequent similar soles may be marked without moving the gauges. For marking the line at the breast, the heel gauge is first positioned. The machine described is adapted to mark the beginning and end of a cut reducing the thickness of the margin at the shank. Specification 327,677, [Class 17 (i), Boots and shoes, Apparatus for making &c.], is referred to.

Title: Improvements relating to the field windings of dynamo-electric machines
Inventor: PARTINGTON WALTER
IPC: H02K3/18
Filed: 1961-08-24
Abstract: 936,598. Coils for dynamo-electric machines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 27, 1962 [Aug. 24, 1961], No. 30565/61. Class 35. Fractional turns in a field coil for a dynamoelectric machine are obtained by adjusting both the position of tappings 3, 5 on the closed electrically conducting ring 1 and the length of insulated connection 2, 4 which overlies the ring to form part of the coil. As shown, current flowing along connection 2 divides at 3 and flows equally through each half of the ring to 5, the whole current flowing in connection 4. The resultant flux is only produced by the current flowing in the connections since the resultant flux produced by the equal and opposite currents in the ring is zero. By altering the position of the tapping points relative to each other an effective flux can be produced by the difference current flowing in the ring and in this way other fractions of turns can be obtained.

Filed: 1930-10-14
Abstract: 363,753. Thrashing-machines. GHISELLI, C. and GHISELLI, F., Sartirana, Pavia, Italy. Oct. 14, 1930, No. 30754. [Class 58.] An automatic feeding plant for thrashing machines of the kind in which an endless belt conveyer and a distributing drum are both actuated from the beater drive through an automatic centrifugal coupling has a feedlimiting device arranged near the discharge end of the conveyer and a distributing drum arranged immediately above the beater to divide said layer into bundles which are fed to the beater. The sheaves have their bands cut and are thrown on the conveyer 1 from stands 7 or over a table 26. They are carried under a limiting device comprised by a number of arms 20 swingable about a pivot 21. Short extensions projecting beyond the pivot are connected to upper springs 22 and lower chains 24. The spacing between the belt and the ends of the arms is adjustable. The belt is driven through worm gear 14 and the automatic centrifugal coupling from the beater pulley 18. The centrifugal coupling comprises a loose pulley 16, driven by a belt from the pulley 18, and a pulley 28 fixed to the shaft 15 of the worm 14. The pulley 16 carries weighted crank levers 30, 32, adjustably secured to bands 51, 52, embracing the pulley 28. The outward throw of the weighted arm due to centrifugal force causes the bands to be drawn tightly round the pulley 28 and so causes the feed conveyer to be driven. Should the rotation speed of the beater diminish the weighted arms are retracted by adjustable springs 39, 40, and the drive to the conveyer stopped thus checking the feed to the beater. The layers of ears are discharged by the conveyer 1 on to a distributing drum 58 arranged above the beater 55 and concave 56 and preferably driven at a much slower speed than the beater. The drum comprises two heads connected by concave surfaces 64 and is provided with rows of curved teeth 66 that serve to divide the ears fed into the thrashing machine into bundles.
