Title: Bending machine for metal rods
IPC: B21D11/12
Filed: 1971-11-01
Abstract: 1361033 Angular bending P F PEDDING- HAUS 1 Nov 1971 [30 Nov 1970] 50608/71 Heading B3E A bar 4 is bent to a predetermined angle and the reverse elastic travel of the bar compensated for by rotating a plate 1 having a pair of bending tools 2, 3 which coact in use with a fixed tool 5; counting on a counter (not shown) the impulses received when an impulse transmitter 14 is actuated by contacts mounted in positions 11-13 on a disc 9 which is rotated with the plate 1, delaying by a preselected period which is proportional to the value of the predetermined bending angle, the value of the ratio of the diameter of the bending tool 2 to the diameter of the bar 4, and a factor having a value lying between 0À004 and 0À008, the moment at which the number of impulses transmitted by the transmitter 14 corresponds to the number of impulses preset on the counter, to allow the plate to rotate through an angle greater than the predetermined angle; and finally reversing the rotation of the plate to return it to a zero position. Each contact, e.g. 15 or 16, Fig. 2, is slidably mounted in a slot 17, or 18 and is engaged by a pivoted lever 20. A disc 23, mounted concentrically with the disc 9, has brackets 25 into which the inner ends of levers 20 project and a scale 26 which is marked with a plurality of values for the ratio of the bending tool diameter to rod diameter. Thus on rotation of disc 23 in a direction 28 there is a proportional increase in the distance by which the contacts 15, 16 are advanced in their slots. If the hardness of rods being bent varies then the radial positions of the pivots of levers 20 are altered. In the embodiment in Fig. 3, each position corresponding to a predetermined bending angle has a group of contacts, e.g. 15, 15<SP>1</SP>. A greater number of impulses can be set on a counter 30 than corresponds to the nominal angle of rotation of the bending plate by a disc 33 and a gear 37, the latter comprising two frusto-conical parts 38, 39 connected by a belt 40. The position of the belt 40 can be adjusted by a fork 41 when there is a change in the ratio of tool diameter to rod diameter. The fork 41 is pivoted to accommodate changes in hardness of the rods.

Abstract: 1404993 Collapsible tubes COLGATEPALMOLIVE CO 3 Nov 1972 [22 Nov 1971] 50822/72 Heading B8D [Also in Division B5] A collapsible tube comprises a longitudinally scanned body, which is made by heat-sealing a turned-back side edge of a blank metal foil 22 lined at least along its edges with thermoplastics 23 to the other side edge, and a integral preformed thermoplastics head 13, which has an inner skirt 26 heat-sealed to the thermoplastics 23 around the body end and outer skirt 28 embracing the body end. In the embodiment illustrated, the thermoplastics extends as a layer over the entire surface of the metal foil, and the head, which may be polyethylene or polypropylene, is of the same thermoplastics material.

In another embodiment, Figs. 5-8 (not shown), the blank is provided with a peripheral border band 33-36 of thermoplastics, and the barrier insert is provided with a stop flange 44. The blank may be provided with an outer layer 24 of thermoplastics sheet for example, and may be of trapezoidal form to permit the forming of nestable tubes.

Title: Automatic locking of high-level luminairs
IPC: F21V21/38
Filed: 1973-11-01
Abstract: 1447383 Lamp supports C C BOEMER 1 Nov 1973 [6 Nov 1972] 50864/73 Heading F4R [Also in Division E2] An annular frame member 24, Fig. 1, carrying lamps (not shown) or other equipment surrounds a mast 10 and can be raised or lowered by means of ropes 22 which pass over pulleys 20, 20.1 journalled at the top of the mast. The member is provided with a plurality of inwardly-directed horizontal pins 32 each of which is adapted to engage in a corresponding vertical channel 38.1 as the member is raised towards the top of the mast. Within each channel is a protruding Z- shaped device 40, Fig. 3, and the pins first engage the sloping underfaces of the lower limbs 40.1 of the devices which impart a limited rotational displacement to the member and thereby deflect the portions of the ropes 22 disposed between the pulleys 20 and respective eye bolts 34 connected to the member. When the pins pass over the top edges 40.4 of the lower limbs the torque applied by the deflected ropes rotates the member back to its original position so that the pins can nest in angular notches 40.5 to support the member at the top of the mast. When it is necessary to lower the member it is first raised slightly thereby causing the pins to slide up the underfaces of the upper limbs 40.2 and the member to undergo a second rotational displacement. As soon as the pins have passed over the top ends 40.6 of the upper limbs the member swings back and moves the pins clear of the notches, leaving the member free to be lowered to the ground. In a modification, Fig. 4, the Z-shaped devices are replaced by brackets 42 carrying rigid fins of the form shown. The pins slide upwardly along the underfaces of the fins 46.3 and nest in the notches 48, release of the member causing the pins to move in the direction of the arrow 50.2 between the fins 46.2 and 46.4 under the action of the torque applied by the ropes as a consequence of their initial deflection. Springs or resilient buffers may be incorporated in the connections of the ropes to the frame member for shock absorbing purposes, and the member may carry inwardly biased stabilizing rollers engaging the mast.
