Title: Improvements in or relating to bending machines
IPC: B21D7/02
Filed: 1960-02-26
Abstract: 943,917. Angular bending. HILMOR Ltd., and E. J. HAMPSON. Feb. 24, 1961 [Feb. 26, 1960], No. 6809/60. Heading B3E. A bending machine of the kind including a bending head arranged to carry out bending movements, a member movable in dependence upon movement of the bending head and a switch arranged to be operated to stop bending movement on inter-engagement of a first abutment and any one of a number of second abutments carried by an abutment carrier, and means to move the abutment carrier stepwise after each bending movement to bring each of the second abutments in turn into line with the first abutment, the first abutment and the abutment carrier being moved towards one another by movement of the movable member resulting from a bending movement of the bending head, is characterized by the provision of spring means to return the abutment carrier to an initial position after a selected number of bending movements have been made. In operation, the number of successive bending movements to be made is selected by inserting a pin 51 on a disc 39 into an appropriate one of a series of bores 49, equally spaced on a circle in a ratchet wheel 42. The first bending movement is then commenced, e.g. the rotation of a bending former around which a tube is bent. The bending head rotates, through chain and sprocket means, threaded shafts 12 and 14. A nut 31 on the shaft 12 is thus moved axially until a stop 34 on an arm 32 thereon abuts an appropriate stop 29 on a carrier 27 on a shaft 28, 23 and moves the carrier and shaft until a cross-piece 25 on the shaft end operates a switch 19 to stop the bending operation. During this movement a nut 66 threaded on the shaft 14 moves axially to allow a spring 65 to move a pawl 63 and connecting rod 64 to the right so that the pawl passes under the lowermost tooth of the ratchet wheel 42, thereafter relative movement occurs between the rod 64 and nut 66. On operation of an appropriate switch the bending head returns to its initial position, the nut 31 moving back until a stop 33 on the arm 32 operates a switch 19A to stop the machine drive and the nut 66 moves back so that the pawl 63 rotates the ratchet wheel 42 one step and thus, through disc 39, shaft 37 and bevel gears 36, 35, turns the carrier 27 one step. A main pawl 44 holds the ratchet wheel 42 in position against the action of a spiral spring 41 on the shaft 37. The cycle of bending movements is repeated until a fixed pin 50 on the ratchet wheel 42 engages a member 48, Fig. 5 (riot shown), to lift the main pawl 44 from engagement with the ratchet wheel 42 and allow the spring 41 to return the wheel 42, disc 39 and carrier 27 to their original positions, the pin 51 moving the member 48 to allow the pawl 44 to stop the ratchet wheel 42. Specification 943,918 is referred to.

IPC: B32B7/02
Filed: 1976-02-23
Abstract: 1519551 Foamed polyolefin sheet material FURUKAWA ELECTRIC CO Ltd 23 Feb 1976 [26 Feb 1975] 07080/76 Heading B5N A foamed polyolefin sheet material is produced by heating under atmospheric pressure a layer of polyolefin supported by a support member, the layer containing a thermally decomposable foaming agent and, if the polyolefin is not already cross-linked, a cross-linking agent therefor, to decompose the foaming agent and activate the cross-linking agent (if any), there being provided between the lower surface of the layer and the support member a film of a non- cross-linked thermoplastic resin free from crosslinking agent, the film being attached to the lower surface of the layer and preventing contact between the layer and the support member during the heating. The polyolefin base layer may be produced by mixing the foaming agent with a polyolefin, forming the mixture into a sheet, e.g. extrusion, and irradiating with ionizing radiation to effect cross-linking, or by mixing the foaming agent and cross-linking agent with the polyolefin and forming the mixture into a sheet. The polyolefin may be of ethylene, propylene or butene which may be copolymerized with vinyl acetate or acrylic acid. The polyolefin may contain rubber or other plastics material or a flame retardant, e.g. antimony oxide or chlorinated paraffin. The foaming agent may be p,p<SP>1</SP>oxybis(benzene sulphonyl hydrazide, azodicarbonamide, dinitroso pentaethylene tetramine or p-toluene-sulphonyl semicarbazide, and the cross-linking agent may be dicumyl peroxide, 1,10-decane-bis-sulphonazide, m-phenylene diazide, vinyltriethoxysilane, vinyl trimethoxysilane, dibutylatin dilaurate and dibutyl tin diacetate which may be used together with triallyl cyanurate or triallyl isocyanurate. The thermoplastic film which may have a thickness of 0À05-1 mm., may be of low or high density polyethylene or polypropylene. The film-fitted sheet may be conveyed on a wire net conveyer, e.g. of stainless steel, through a furnace to effect foaming. A film may be applied to both surfaces of the sheet. The film fitted surface of a foamed sheet may be bonded to the heated surface of an iron plate, the other surface of which is covered with an embossed sheet of vinyl chloride resin.

Filed: 1975-02-20
Abstract: 1500161 Servo-assisted steering gear ROBERT BOSCH GmbH 20 Feb 1975 [21 Feb 1974] 7126/75 Addition to 1469185 Heading B7H In a servo-assisted steering gear for a motor vehicle including a toothed rack 6 engaged with a pinion 5 disposed on a steering shaft 1, a servo 12 is arranged to assist movements of the rack for steering, and a control valve 17 for actuating the servomotor is operable to deactivate the servomotor in response to displacement of the rack into either one of its axial end positions. As shown in Fig. 1, a pinion 5 is rotated anticlockwise by steering shaft 1 including a Cardan joint 3, and the pinion 5 initially rides along teeth 7 to the left thus pivoting lever 22 which displaces rod 20 for actuating valve 17. Thus the appropriate chamber, i.e. 13 of the servomotor 17 is pressurized to move the rack 6 to the right until in the fully displaced position, the tooth end 9 acts as a stop to prevent pinion 5 riding further along the rack. Chamber 13, however, is still pressurized so that rod 10 and rack 6 together with pinion 5 move toward the right thus pivoting lever 22 into the initial neutral position. Thus the toothed rack ceases to be displaced to the right. Displacement and arresting'of the rack towards the left is effected in a similar, reverse, manner. In a modification, Fig. 4, the lever 22 has an extension 28 which co-operates with stops 25, 26 mounted on a side face of the rack. The pinion 5 may be guided in a movable bearing arranged parallel to the rack 6.

Abstract: 493,683. Wireless transmitting-apparatus. LORENZ AKT.-GES., C. March 11, 1938, No. 7647. Convention date, March 11, 1937. [Class 40 (v)] Direction transmitters, as used for marking-out a navigational course, are keyed at predetermined frequencies and with given signal-to-gapratios, as indicated at a, and b in Fig. 1, by electromagnetic relays which are suitably inter-connected and timed. As shown in Fig. 3, the relays I, II, timed respectively by resistances W1, W2, control the consecutive keying at 21 of the beam aerial E, whilst a third relay III, switched in at S, allows a change from one keying frequency to another. When the starting switch A is closed, the relay I is first energized over the resistance W1 and contacts 3, 2. It closes contact 1 to energize relay II over resistance W2, thus opening contact 2 and de-energizing relay I, which, after a certain interval, opens contact 1 in the circuit of relay II. The latter releases, after a certain period, to close contact 2. The relay I is then energized and the cycle is repeated. If the relay III is included, the keying frequency is reduced.

Title: Improvements in or relating to Collars for Personal Wear.
Inventor: HEUSEN JOHN MANNING VAN
IPC: A41B5/00
Filed: 1918-05-10
Abstract: 116,090. Heusen, J. M. van, (Assignee of Morgan, J. L.). May 22, 1917, [Convention date]. Fashioned fabrics, looms specially designed for. -Double collars of multi-ply fabric are made by weaving, under the same tension, the outer and inner folds in such a way that the outer fold is longer than the inner one, whereby the collar takes a permanent curvilinear set when folded. The intermediate edge fold portion is also woven under the same tension, but with less warp threads, so that is weakened. The fabric for making the collars is woven by taking the warp and binder threads from rolls 1, over guide-rolls 2, through spacing-frames 3, around guide-rolls 4, through thread-supporting loops of the heald frame 6, and through a reed 7 carried by a beam 8. The completed fabric is carried over a skew guide-rod 10, and between tapered tension rolls 11, 12, to the take-up roll 13. The rolls 11, 12 produce the required uniform tension on the threads, whereby the greatest length of thread is on one edge, the length gradually diminishing towards the other edge. Fig. 5 shows a cross-section of the fabric, wherein the weft threads 17 of the three-ply fabric are connected by binder threads 21, 22, and the warp threads 20 of the intermediate layer are omitted at the centre so as to form the weakened edge fold portion 23. The weakened edge may also be produced by omitting warp threads from one of the outer layers, or from one of the outer layers and also from the intermediate layer. The collar is stamped out of the fabric, bound, and finished in the usual way. Specifications 110,942, [Class 142 (iv), Woven fabrics &c.], and 116,092 are referred to.
