Title: An improved device for use in bending metal bars
IPC: B21D11/12
Filed: 1954-01-29
Abstract: 751,971. Bending-jigs. BAARSEN, A. VAN. Jan. 29, 1954, No. 2719/54. Class 83 (4). [Also in Group XXIII] A device for use in bending metal bars comprises a longitudinally extending clamping bench in which a number of separate bending- jigs are clampingly secured at adjustable distances from one another, each bending- jig comprising a casing and a pair of bending-pegs projecting upwardly from said casing. Each bending-jig comprises a pair of pegs 1, 11 on the end of a block 2 longitudinally slidable in a cylindrical casing comprising an inner sleeve 6 and an outer sleeve 8 welded to end plates 10, 11, the plate 11 projecting as a flange beyond the sleeve 8. The block 2 has rack teeth 3 which mesh with a sector 4 extending through a slot in the casing and rocked by a handle 16. The outer sleeve 8 of the casing is held in a resilient frame comprising two clamping blocks 13 connected by spring strips 15 so that the jig may be rotated in the frame to adjust the pegs 1, 1<SP>1</SP> when there is no pressure on the blocks 13. A number of jigs are placed a suitable distance apart between beams 14 of a clamping bench with the flanges of the plates 11 resting on the beams and the angle of the base line between the pegs 1, 1<SP>1</SP> of each jig with the longitudinal axis of the clamping bench adjusted according to the thickness of bar to be bent. The tools are then clamped in position between the beams 14 by bolts 18. A bar, or bars, 19 is placed between the pegs and its end is bent, by suitable means, around a peg of the end jig to form the first bend. The pegs of this jig are then lowered by the handle 16 and the bar bent about a peg of the next jig and so on.

Title: Improvements in or relating to animal racing apparatus
IPC: A63K1/02
Filed: 1927-02-01
Abstract: 271,775. Heintz, G., W., '(Assignee of Thurn, W. A.). Nov. 29, 1926, [Convention date]. Dog-racing apparatus of the kind in which an artificial lure is carried round a track on a car, is provided with an opening in the housing enclosing the car through which the lure is removed at the conclusion of a race, an electrically operated device being employed to close the opening. The car C carries an arm D with the lure E, the arm being mounted on a vertical shaft having a spring 10<a>. A lug 11 on the inner end of the arm is held by a pawl 7 until an arm 9 on the lower end of the shaft 8 carrying the pawl engages a tripping device 15 in the track. The lug 11 being released from the, pawl 7, the arm D is withdrawn inside the housing B. A door F is raised by an electromagnet 13 for the passage of the lure E. The tripping device 15 is set by an electromagnet 16 controlled by a switch H, itself actuated by the passage of the car. On the start of a race, a roller 8<a> on the shaft 8 engages a lever 17 that rotates a disc 18 by means of a pawl 20, causing segmental contacts 19 to close the circuits of the electromagnets 13, 16, after which a spring 22 returns the lever to its original position. When the car has completed a lap of the circuit, the arm 9 engages the trip 15, allowing the lure E to move through the door F, shock being absorbed by the device 12, and the roller 8<a> moves the switch H to open position. The car then returns to its starting position, and the arm D is again extended by its engagement with a member 28 secured to the roof of the housing. A mask 20<a> prevents the pawl 20 from rotating the switch when the arm 17 returns to normal position after being struck by the roller 8<a> during this return movement.

Title: Treatment of metal surfaces to inhibit tarnishing or corrosion thereof
Inventor: HOWARD DONALD KEAREY
IPC: C23F11/08
Filed: 1964-01-24
Abstract: A process of treating a surface of Cu or of a Cu alloy to inhibit tarnishing or corrosion thereof comprises contacting the surface with a mixture (e.g. a solution or dispersion) of a water-soluble ferricyanide with at least one benzotriazole compound.  The term benzotriazole compound includes benzotriazole itself and Cu-protecting derivatives thereof such as 5-alkylbenzotriazole or a 5-acylaminobenzotriazole.  Examples of such compounds are given in Specifications 1,065,995 and 1,069,392.  The ferricyanide may be ammonium or alkali metal ferricyanide or a mixture of two or more thereof.  Before contacting with the mixture, the Cu may be contacted with a solution of chromate or dichromate or mixture of two or more thereof or with a solution of soap as described in Specification 1,065,997.  Contact with the mixture containing a benzotriazole compound may be for 0.5 to 30 minutes at a temperature from 10 DEG C. to the boiling point of the mixture.  In the Example, Cu foil is cleaned in acid solution, washed, immersed for 2 minutes in an aqueous solution containing 0.1% by weight of benzotriazole and 0.05% by weight of potassium ferricyanide at 65 DEG C., washed, dried and then tested for tarnish resistance with H2S.

Title: Method and device for winding up threads particularly of synthetic materials
IPC: D01H1/06
Filed: 1963-01-25
Abstract: 980,488. Winding yarns spinning apparatus. E. BLASCHKE. Jan. 25, 1963 [Jan. 25, 1962], No. 3149/63. Headings D1D and D1J. [Also in Division G3]  Thread 9 is wound on to a rotating bobbin 1 by means of a bow shaped member or flyer 4, which rotates in the reverse direction to that of the bobbin and which straddles the bobbin and conducts the thread thereto through a passage 5. The linear speed of feeding the thread 9 is then equal to the sum of the rotational speeds of the bobbin 1 and bow 4 multiplied by the cumference of the package 2. A compressed air nozzle 10 is employed to blow the thread into the guide passage 5 and the nozzle 10 is swivelable so that when winding has to be interrupted, e.g. for bobbin changing, the nozzle may be turned as indicated to blow the thread into a funnel 14 and suitable collecting means so that the feed of thread is not interrupted. The speed of rotation of the bobbin may be controlled as the package grows, through electronic control means 13 operating in conjunction with a tension sensing device 12 to give the required tension or to match the desired feed rate of the thread. The bobbin may be reciprocated vertically by hydraulic means 11, the stroke being variable to form a package of the required shape. Rotation of the bow imparts a measure of twist to the thread which is stated to be advantageous in the case of threads of synthetic material. Since the winding of the thread is effected both by rotation of the bow 4 and by rotation of the bobbin 1 high winding speeds can be attained without running the bobbin at speeds which would result in badly formed packages owing to the effects. of centrifugal forces on the threads. The invention is stated to be of particular value in the high speed winding of synthetic thread which has been stretched after the spinning process and which may be fed at speeds up to 6000 metres/min.

Abstract: 212,053. Starkey, T. R. Feb. 2, 1923. Retorts and methods of working.-In the low or medium temperature distillation of shale, bituminous coal, &c., the material is passed through a series of chambers heated externally by double walled partitions through which hot gas flows counter to the direction of the passage of the material through the chambers, and steam, oil vapour or other gas is passed through hollow rabbles into the chambers, the distillation products being withdrawn from any or all of the chambers. A retort is divided into a number of chambers 14 by horizontal double walled partitions 15, 16 enclosing between them heating spaces 17 traversed by hot gases passing from an inlet 34 to an outlet 35.
