Title: Improvements in and relating to braiding machines
IPC: D04C3/00
Filed: 1937-06-29
Abstract: 485,059. Braiding-machines. LANNON, J. J. June 29, 1937, No. 18063. Convention date, Oct. 23, 1936. [Class 74 (i)] In a machine adapted for braiding heavy, stiff, or otherwise intractable material, e.g. metal ribbon, flat strands of parallel wires, 10-cord cotton thread, rope yarn &c., the following features arc embodied : to a spider 4 mounted on posts is bolted a cam. ring 7 the flange 9 of which is inclined to the vertical at about 8. The groove 10 operates strand guiding arms 84 pivoted at 83a to the flange 35 of the rotary inner carrier support 32. Each strand passes round a pulley situated near the pivot 83a and round another pulley at the end of the arm 84, the pulleys being set approximately at right-angles to each other. The support 32 is provided with two tracks 36, 39 for rollers such as 60 carried by inner supplies C. A vertical shaft 43 drives the support 32 through a pinion 42 gearing with an annulus 41 and also drives the supplies C, the opposite way, through a pinion 52 acting on an annulus 30. The annulus 30 carries a crown wheel 26 which gears with bevel wheels 56 on radial shafts 55 mounted on the support 32. The outer ends of the shaft 55 carry wheels 57 gearing with short racks 62 on the supplies C. The length of the racks 62 and the number of the shafts 55 are such that each rack is always in gear with at least one wheel 57. The strands from the upper and outer supplies D are passed by the arms 84 through the spaces between the racks. The supplies D are mounted sideways on the flange 35. Convex rolls 82 tend to guide the strands to a central point regardless of the positions they occupied on the spools 73. Before the supply of material in any spool or bobbin 64, 73 is exhausted a stop-motion is set in action which breaks the driving motor circuit. In the case of the supplies C, detector fingers 66 engage swinging arms 135 which engage a swinging arm 119 connected to the stop-motion. In the case of the supplies D the arm 119 is engaged by feelers 118. The take-up drive includes change gears whereby the linear velocity of take-up may be varied at will. The braiding die is so placed that the strands from the supplies C pass up to the braiding-point at an angle of 8 to the horizontal.

Title: Switching apparatus
Inventor: WAGNER HANS-DIETER
Filed: 1970-04-17
Abstract: 1280751 Starting prime movers KOMBINAT ELEKTROMASCHINENBAU VEB 17 April 1970 18501/70 Heading H2H  A circuit for the starter motor of a prime mover is provided with means whereby rerepeated operation of the starter motor is inhibited. Operation of a starter switch 1 into its first position energizes a relay 7 to close contacts d7 whereupon an ignition warning lamp 10 is illuminated. When the starter switch is moved to its second or starting position a relay 8 is closed by way of a normally closed contact d9 of a further relay d9. Contacts of 8 thereupon close thus energizing a solenoid operated switch to operate the starter motor 5, the motor current flowing through a current operated relay 6. The heavy initial motor current causes operation of the relay 6 to close various contacts d6. One of these latter contacts causes a lamp 11 to be illuminated to indicate that the starting operation is being performed, another contact d6 short circuits the contact d9 in the circuit of relay 8 and the third contact d6 causes energization of the relay 9 which is provided with a self holding contact d9. The contact d9 in the circuit of relay 8 opens but the relay remains energized by way of the closed contacts d6. As the starting operation proceeds the motor current falls off until, at a predetermined value of current, the relay 6 is insufficiently energized whereupon the contacts d6 open. The lamp 11 extinguishes to indicate the end of the starting operation since, with the relay 9 remaining energized the relay 8 becomes de-energized by virtue of the contacts d9 in its circuit remaining open. The contact d8 thus opens to de-energize the solenoid operated switch so de-energizing the motor'5. To repeat the starting operation it is first necessary to return the switch 1 to its OFF position thus de-energizing relay 7 and, by virtue of the opening of contacts d7, relay 9.

Abstract: 893,154. Anti-breakage flaps in shoots. PLOWRIGHT BROS. Ltd. May 30, 1960 [May 30, 1959], No. 18504/59. Classes 78 (1) and 78 (4). Hinging of an anti-breakage flap 5 (Fig. 1) controlling the passage of material through a shoot 1 is controlled by compression springs 8, which tend to lower the flap, and by tensionsprings 10 which over-ride the compression spring 8 to restore the flap to the closed position shown. A pneumatic or hydraulic damper 18 further controls the movement of the flap. The compression springs 8 are pre-stressed by adjusting a nut 31 (Fig. 3) and act on an arm 15 free on the hinge 16 of the flap 5 and connected to an arm 20 fast on the shaft by an adjustable abutment 25. The abutment 25 may be adjusted so that the springs 8 help to hold the flap 5 in its closed position but pass over a deadcentre position after a brief opening movement of the flap. A turnbuckle 9 (Fig. 1) permits adjustment of the initial tension in the springs 10 which are arranged in groups of three. In an alternative construction the tension-springs 10 are replaced by compression springs connected to the flap 5 at the opposite side of the hinge 16, and the pneumatic damper 18 is replaced by a pneumatic or hydraulic damper of the pivoted arm type.

Abstract: 571,228. Making electric contacts. IGRANIC ELECTRIC CO., Ltd. Nov. 11, 1943, No. 18768. Convention date, Nov. 12, 1942. [Classes 83 (ii) and 83 (iv)] [Also in Groups II, XXXVI and XXXVII] Electric contact members are moulded from powdered metal with the incorporation at one face of a piece of gauze or expanded metal to serve as reinforcement and to facilitate electric welding or brazing to a support. A lower die formed by parts 21, 22, Fig. 14, has a plate 23 above of such thickness that the powdered metal is filled into the die level with the top surface of the plate. A corresponding plate 24 is separated from the plate 23, on the upstroke of the press, by springs 26 to permit the feeding of a strip of wire gauze between the plates. On the downstroke the punch 25 shears a blank from the strip and consolidates the powder, forcing it into the meshes and wholly or partly round the wires as at 20c, Fig. 5. The contact is moulded with a,convex upper surface and may be of elongated or circular &c. form. It may be given a number of projections 28c, Figs. 7 and 8, on the reinforced side further to facilitate welding &c. by reducing the initial contact area. The dies of the press are electrically heated at x, y in known manner. The moulding pressure is about 40,000 lbs. at a temperature of 400‹ F. The reinforcement may be preformed and may be placed in the die below the powder. The powder may be, in parts by weight, precipitated silver 67, crystalline silver of 80 mesh or finer 22, and cadmium sulphide 11, as described in U.S.A. Specification 2,288,122.

As in the apparatus described in Specification 1268083, the element 20 is reciprocated radially above the disc 21 in synchronism with the rotation of the disc and is reciprocated perpendicularly to the disc to produce the stroke marks. Each stroke may represent a unit, ten or a hundred pieces and so on i. e. decadic stage and the appropriate stage is selected to obtain good resolution without waste of recording material assuming a standard rate of rotation of the disc. By recording strokes in two tracks 56, 57 the resolution of the selected stage can be improved. Using the control switch 58, Fig. 3, the piece pulses are divided by a flip-flop stage 51 with its outputs connected by AND gates 62, 63 to writing contacts 59, 60, of rotary switch 23. Instead of causing one element 20 to record alternately in the two tracks 56, 57, two separate elements could be similarly controlled. The resolution can be further improved by distributing the strokes sequentially over more than two tracks using a mechanical Maltese Cross switching device (instead of the electronic switching device) to scan writing contacts corresponding respectively to the tracks.
