Title: Improvements relating to bending machines for bending metal bars
Inventor: GOBLE HARRY
IPC: B21D7/06
Filed: 1966-11-29
Abstract: 1,200,178. Angular bending; straightening; making bumpers. H. GOBLE. 23 Nov., 1967 [29 Nov., 1966], No. 53358/66. Headings B3A and B3E. A metal bar bending machine, particularly to shape car bumpers with a straight portion 24 and curved ends 26, comprises a clamp 32 and a pair of curving dies 50, 52 mounted on a saddle 40 slidable in a slot 30 at each side of the clamp. The dies each have hardened metal inserts 54 which extend over the initial part of the curved opening. The inner die 50 is pivoted to the saddle about a pin 68 and is movable by a piston cylinder assembly 84 to separate the dies. The pin 68 is mounted on a slide (70), Fig. 5 (not shown), which is spring-biased away from the outer die 52 between guides 72. A cam follower 74 prevents the slide moving the inner die away from the outer die until it has been pivoted by a small amount about the pin 68 in a direction opposite to the direction of entry of the bar. An internal die 66 for the hollow bar is mounted on a shank 94 which extends through the longitudinal slot in the bar. The thickness of the die 66 is such that it can be removed through the slot after it has been rotated through 90 degrees. A back-up member 101 prevents distortion of the die and the member is removed from behind the die before the rotation. The curved ends of the bar which extend beyond the dies 50, 52 when the saddles are in their innermost positions are each straightened between an anvil die 130 and a wiper die 132. The die 130 is mounted on an arm 134 adjustably positioned about an axis 136 on the saddle 40. The wiper die 132 is mounted on a slide 142 movable between guides 144 adjustably positioned on a slotted table 120. The end of the slide has rollers which engage an adjustable surface 152 so that when the motor 128 rotates the nut 126 the table is moved to cause the die 132 to co-operate with the die 130 to straighten the curve. The die 130 and the surface 152 are mounted parallel to form a straight portion at each end of the bar although they may both have any similar curvature. The central part of the bar is prevented from buckling by clamps 36 which are slidable along the bar and urged apart by springs 38. When the saddles 40 are moved together by the piston cylinder assemblies 44 the clamps 36 are brought closer together. The actuation of the power cylinders and the electric motors 128 are preferably arranged to operate automatically in a preset sequence.

Title: Improvements in and relating to spring systems
Inventor: LEEUWEN GERRIT HENDRIK VAN
IPC: B60G3/00
Filed: 1969-11-13
Abstract: 1,248,322. Spring suspensions. G. H. VAN LEEUWEN. 13 Nov., 1969 [3 Dec., 1968], No. 55663/69. Heading B7D. [Also in Division F2] Two bodies, in particular a vehicle chassis 9 and a wheel, are interconnected by two levers and two springs. The first lever 1 is pivoted at 2 to the first body (chassis) and a first spring 7 acts between the chassis and this lever. The second body (wheel) is connected to a second lever 16 which is pivoted to the first lever, and a second spring 12 acts between the two levers. As shown, the pivotal interconnection between the two levers is coincident with the pivot 2 between the first lever and the chassis, but the two pivot axes need not coincide. Also, the two springs are shown on opposite sides of the pivot 2: it is, however, possible to locate the first spring at the pivot 2, e.g. by making the pivotal connection between the lever 1 and the chassis in the form of a resilient stub-shaft which acts as a torsion spring, and eliminating the coil spring 7. Resilient bump stops 20, 21 may also be provided on the levers. In use as a vehicle suspension, slight shocks imparted to the wheel stress only the spring 12; heavier shocks stress the other spring. Fig. 3 (not shown) has a combined coil spring and air bellows in place of the simple coil spring 7 of Fig. 1 and a spherical rubber spring in place of the coil spring 12. In Figs. 4 to 6 (not shown), the two pivot axes are non-coincident but parallel and each comprises a torsion rod constituting the respective springs. Fig. 7 (not shown) similarly employs torsion rods as combined springs and pivots, but their axes are mutually perpendicular. The use of shock absorbers in combination with the springs is mentioned: so also is the possibility of employing magnetic springs.

Moving prism 19 in direction 35 at right angles to direction 29 shifts the optical axis without change of path length. The prisms 11, 19 may have their hypotenuse sides 15, 21 parallel Fig. 1 alternatively Fig. 2 (not shown) prism 19 may be inverted, so that the faces 17 and 23 are coplanor, and the 30 degree apices of the prisms lie adjacent each other, a mirror (41) being provided in a plane parallel to the faces 17, 23 between the two prisms; this provides an odd number of reflections so that the apparatus can be used in a system providing image roll. Shifting of the optical axis in a second direction, and also image roll, may be obtained by providing face 17 with a roof prism; movement of prism 11  perpendicular to the plane of Fig. 1 then shifts the optical axis in that direction.

Abstract: 1445185 Data transmission; phase modulation SIEMENS AG 6 Dec 1973 [15 May 1973] 56553/73 Heading H4P A frequency differential phase modulation system is arranged so that the change in only one bit in incoming data groups changes transmitted signals by the smallest significant phase rotation, i.e. in a 4 phase system with each phase representing two successive bits, a change in one bit causes a rotation of 90 degrees. Incoming data is recorded into groups of monotonic progression, i.e. Gray code each group being assigned to monotonously increasing phase rotations. If more than two line frequecies are to be simultaneously phase modulated, outputs from the recorder may be serially passed into registers then parallelly via a buffer store to phase modulators, one for each frequency. A known recoder Z01, K3, K4 may be used which from serial parallel converter SPU receives parallel signals c, d; output signals e, f are fed back via stores K3, K4 to inputs a, b or an additional allocator Z02 may be incorporated giving lower technical outley, for phase modulator PM which is stated to be increasingly advantageous for mulitple phase modulators served by a common recorder. A 3-bit eight phase system is envisaged in the Specification. Phase modulators may be formed by half adders (see Fig. 6, not shown).

Abstract: 1402867 Stacking vehicles BRITISH STEEL CORP and LAMBERTON & CO Ltd 14 Dec 1972 [17 Dec 1971] 58749/71 Heading B8C Lengths of ferromagnetic material are stacked by loading each length cross-wise on to a conveyer at a loading station from which it is moved to an unloading station where it is transferred by a rotatable electromagnet to a support surface. As shown, ferromagnetic sections 17 are transferred by a pusher 18 from a roller table 16 on to a three-section belt conveyer 11 running over pulleys 12, 13. Electromagnets having polepieces 21 which are freely rotatable about cores (22), Fig. 1 (not shown), are located between the pulleys 13 so that as the sections approach the pulleys 13 they are carried by the polepieces 21 to a position 30 at which the polepieces are braked by discs (28) and the electromagnets are deactivated to cause the sections 17 to be deposited on a pile 31 supported by tables 51. Means for inverting alternate sections 17 comprises magnets 35 having face plates 36 and carried on arms 37 which are pivoted at 38, the arms being balanced by counterweights (39). Further plates 41 having stops 42 are pivoted to the plates 36 and rest on pins 43. The arrangement being such that a section 17 required to be inverted travels on the belts 11, is stopped by stops 42, the arms 37 are driven upwards about pivots 38 and the magnets 35 engage the plates 41 which are lifted, with the section 17, away from the belts 17. Rotary movement of the arms 37 continues until the section falls on to the belts 11, against stops 46. As the arms are returned to their original positions, the stops 46 are withdrawn. Where sections are not required to be inverted, the arms are retracted below the belts 11. The tables 51 are raised and lowered hydraulically and in the lowest position each pile is removed by trolleys 52 driven by rack and pinion gearing 54 towards stops 56 at which the pile is raised from its trolley by a ramp 57. The whole apparatus is carried on rails 61 to allow it to co-operate with storage areas along the length of the table 16. In another arrangement, Fig. 3 (not shown), inversion of selected sections is achieved by an additional conveyer (73) pivoted about the axis of pulley 12, which is effective to lift sections off the belts 11 which are then carried by the conveyer (73) and allowed to fall therefrom on to the belts 11. The electromagnets 21, 23 may be motor driven. Specification 57502/71 is referred to.
