Abstract: 1487129 Conveying wire EVG ENTWICKLUNGS-U VERWERTUNGS-GmbH 19 Dec 1975 [20 Dec 1974] 52170/75 Heading B8A Wire 1 is fed longitudinally between pairs of guide rollers 2, 2<SP>1</SP>, by the action of grippers 7, 7<SP>1</SP>, carried at apices of polygonal driven rotors 5, 6. The grippers are mounted on a carrier 6 which itself is mounted on an eccentric shaft portion 15. As this is rotated by a motor 10 and gearing 12, 13,thegripper carrier 6 is rotated relative to the eccentric portion 15 by planet gearing 16, 17. The combination of the two rotations produces a straight line movement of the grippers during their gripping action. The grippers come into use alternately and with an overlap in time so that there is a continuous feeding action on the wire. In Fig. 3 the grippers are actuated hydraulically, pressure oil being supplied via a flexible conduit 30 and a circumferential port 35 so as to act on an interior bore of each gripper. The circumferential port is shaped so as to cut off the pressure liquid except for the part of rotation of the rotor in which the grippers are intended to operate. In other modifications (Figs. 4-7, not shown) the grippers are actuated mechanically by cam action.

Title: Current driver circuit
IPC: A21C5/06
Filed: 1965-12-13
Abstract: 1,097,919. Pulse circuits; circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 13, 1965 [Dec. 17, 1964], No. 52763/65. Headings H3B and H3T. A line is terminated at each end by an impedance which is effectively a short circuit so that an input current pulse will build up by successive reflection, the impedance at the output end being such that it increases stepwise when the current exceeds a given value. Thus, in Fig. 2, the current supplied when transistor 20 is made conductive builds up step-wise by reflection until it exceeds the current supplied by 30 to a diode 24 which effectively short circuited the line, whereupon the diode cutsoff, leaving the line terminated in its characteristic impedance 22. In Fig. 3, the line is the drive wire 58 of a core matrix. To set the cores, write timing pulses are applied to switching units 44 and 46 and to the current generator 62. Current builds up by reflection at each end until it is sufficient to cut off the diode 60. It is explained that the cores are thus switched more quickly than with the previous arrangement. Reading is effected by similarly pulsing units 48, 50 and 64. Diodes 52 are inserted for isolating purposes. Coincident half current-pulse technique may alternatively be used.

Title: Alarm clock
IPC: G04C23/06
Filed: 1973-11-14
Abstract: 1455857 Alarm clocks GENERAL ELECTRIC CO 14 Nov 1973 [27 Aug 1973] 52947/73 Heading G3T  In a clock having an alarm vibrator 114, Fig. 4, which is normally restrained by a lever 110 but which may be released to sound the alarm, the lever has a pair of arms 170, 172 by means of which it is pivotally mounted on the edge of a frame plate 35 and a cam groove 180 which is engaged by one end of an axially slidable rod 112 so that the lever is held in position between the plate and the rod, and the rod couples the lever to the alarm release mechanism. The latter comprises a manually set cam 108 and a cam gear 94 which is rotated twice per day by the clock train and moves axially when the cam parts become aligned, shortly before the alarm time, under the force of a spring 148 acting between the plate 35 and a collar 146 on the rod. The full movement of the rod is, however, prevented by engagement of a further collar 202 on the rod with an arm 208 of a repeat/drowse lever 200 until a lug 92 on a wheel 76 which is rotated once every ten minutes engages a further arm 210 of the lever 200 to rotate the latter against the bias of a spring (214), Fig. 3 (not shown), whereupon the arm 208 moves off the side of the collar 202 and the vibrator is freed. Depression of a drowse button (222), Fig. 1 (not shown) causes lever 136 which couples the cam gear 94 to the rod 112 to pivot about its mounting apertures 154, 156 thus moving the rod 112 to the right until the arm 208 comes back behind the collar 202. The vibrator is then held silent until the lug 92 again displaces the lever 200. The alarm can be permanently silenced by a lever 400 having a cam 402 to move the lever 136 and rod 112 to the right. An automatic shut-off lever 300, pivotally mounted in a groove'306 in a frame post 72, has one arm with a slotted end to embrace the rod 112 and engage the left side of collar 146 and a second arm 302 for engagement by a lug 304 on a gear 40. The latter is rotated once per minute by motor output pinion 42 so that the lug causes the lever 300 to pivot about the groove 306 and displace the rod to the right to silence the alarm. The rod is again held in this position by the collar 202 and lever 200 until subsequent release by the lug 92. The clock is a digital clock with three display drums 22, 26, 30, Fig. 5, the gear 40 also having a finger 38 to advance the units of minutes drum 2, and the wheel 76 driving the tens of minutes drum 26.

Title: Improvements in flying two-drum shears for cutting rolled stock
IPC: B21F11/00
Filed: 1965-12-15
Abstract: 1,087,069. Shearing. SCHLOEMANN A.G. Dec. 15, 1965 [Jan. 9, 1965], No. 53314/65. Heading B3W. In a roller cutter flying shear one of the cutter drums 7 has a blade 3 fixed therein and the other drum 8 has a blade 4 which is integral with a piston 4a which slides in a cylinder 10 formed in the drum. The space above the piston is filled with a liquid in which pressure waves are produced by the discharge of a capacitor 16 between two electrodes 17 and 18. The piston is biased by a spring 11 to move the blade 4 to its retracted position. Operation.-Both drums rotate continuously in the directions indicated by the arrows, the work which is fed by rollers 2 and subsequently passes on to a roller table 6, and the speed of the drums is adjusted to bring the cutters into line when the desired length of material has passed through the shear. A high-tension switch 14 is closed to connect the capacitor 16 to the electrodes 17 and 18 via slip-rings 8a and 8b and the cutter 4 is thus projected towards the stock at a high speed. In a modification, Fig. 2 (not shown), the drums do not rotate continuously but are stationary before the cut and at the instant of cutting are rocked through an angle # by means of a fluid cylinder (22) connected to the drum 8, which drives the drum 7 by toothed segments (25 and 26). In a second modification which may be used when thick material is to be cut, there is no drive to the drums, the lower blade 3 being fixed and the upper blade 4 being pushed away by the cut surface of the following material. The pressure waves may also be produced by pneumaticmechanical methods, by the explosion of a gaseous or liquid substance or by magnetic methods.

Abstract: 1,150,458. Laminated pigmented unitary films. E. I. DU PONT DE NEMOURS & CO. 5 Dec., 1966 [6 Dec., 1965], No. 54332/66. Heading B5B. An integral biaxially oriented film of organic thermoplastic polymeric material has at least two strata characterized in that each of the contiguous strata contains an opacifying coloration pigment differing from or the same as that contained by the other stratum, in the same or in a different concentration. Each stratum contains 0À5 to 60% by weight, based on the polymeric material in the stratum, of the opacifying coloration pigment. The film is also characterized in that at least one of the variables, the thermoplastic material, the opacifying coloration pigment and the pigment concentration is different. One of the film strata may be more opaque than the other or others. The pigment may be titanium dioxide or carbon black. The organic thermoplastic material may be polyvinyl fluoride. The colour of one stratum may differ from that of the adjacent stratum. There may be no distinct interface between adjacent strata of the film. An integral biaxially oriented film of organic thermoplastic polymeric material having a plurality of strata wherein at least one stratum contains opacifying coloration pigment may be made by simultaneously melt extruding two or more pigmented melts corresponding to the strata of the film to be formed through contiguous slot dies to form separate flat films which are contacted while they are still hot plastic and adhesive and bonding these together to form a composite stratified film. The film is then quenched and elongated and widened to orient it biaxially. The unitary film may be made by heating and mixing two or more mixtures comprising polyvinyl fluoride, a latent solvent for polyvinyl fluoride and the same or different opacifying coloration pigments in the same or different amounts to form homogeneous single phase liquid compositions, simultaneously extruding two or more films from the compositions, contacting the films to form an integral film; quenching the integral film and stretching it in two mutually perpendicular directions while simultaneously evolving latent solvent therefrom followed by drying the film to remove substantially all of the remaining latent solvent.
