Abstract: 485,460. Cutting sheet materials &c. into lengths. S. & S. CORRUGATED PAPER MACHINERY CO., Inc. Oct. 16, 1936, No. 28200. Convention date, Oct. 21, 1935. [Class 31 (i)] [Also in Group XXII] In a machine for cutting paper, corrugated board, sheet metal, wire, &c. into lengths, in which the material is fed at constant speed to a continuously rotating cutter which is driven at a variable speed through each cycle, means is provided for varying the period of the cycle to alter the length cut off while maintaining the speed of the cutter at the instant of cutting constant and equal to that of the material. In the construction shown in Fig. 1, the mainshaft drives the feed rolls 1, 3 through sprocketgearing 6, 5, 4, and the cutter rolls 37, 42 through a Reeves drive 8, 8<1>, 9 and sprocketgearing 45, 44, 43<1>. The belt 8<1> is moved to vary the speed of the cutters during each cycle by a sliding fork 10 controlled by a cam 28 on the cutter shaft 29 acting through a roller 27 on an arm 24, shaft 23, arm 22, turnbuckle 17, arm 14, shaft 13, toothed sector 12 and rack 11. The arm 24 is adjustable along the cam 28 by a manually operable screw 34 to vary the period of a cycle. The cam 28 is of constant radius along the line of the cutter 38 to maintain the speed at the instant of cutting constant. In a modification, the cam controls a variable speed hydraulic pump-motor unit which varies the speed of the cutters. To assist the acceleration and deceleration of the cutters, the cutter shaft 152, Fig. 12, carries an eccentric 178 which during deceleration of the cutters rocks a lever 180 to compress a spring 185 to store energy which is released during subsequent acceleration of the cutters. In the construction shown in Fig. 6, the main shaft 85 drives the feed rolls 93, 94 through gearing 86, 87 and sprocket-gearing 89, 90, 91, and the cutter rolls 120, 123 through sprocket-gearing 100, a gear 102 and one of a number of eccentric gears 103 of the same form as the cam 28, Fig. 1. The gear 102 is carried by a spring-pressed arm 98 mounted on a sleeve 97 keyed to and slidable along the shaft 85. A lug 115 co-operates with a slotted bar 117 to allow movement of the arm 98 along the shaft 85 by means of a member 108 only when the gear 102 meshes with the portions of the gears 103 which are all of the same radius. The member 108 is held in adjusted position by a pivoted latch 113. In a modification, the gears 103 are replaced by a cam as in Fig. 1 and the gear 102 by a belt running over pulleys on a pivoted arm similar to 98.

A visual display arrangement for a p.p.i. radar system comprises a rotating transparent disc 1, Fig. 1, coated with a film 2 of magnetooptic Faraday effect material e.g. manganese bismuth, and a radial line array of electromagnetic probes 6, the tips of the respective magnetic cores of which are in close proximity to the film 2. In operation the magnetic probes are each connected individually in turn to the radar receiver 7 by means of electronic switching devices 8 and the visual p.p.i. display is produced by evenly illuminating the disc with a source of plane polarized light, the transmitted or reflected light, Figs. 2(a) and 2(b) (not shown), being viewed via an analyser. To improve the response of the Faraday material it may be bombarded with an electron beam to raise its temperature above its Curie point. To give the disc the appearance of being stationary to an observer a rotating mirror assembly is associated with the rotating disc, Fig. 3 (not shown). The magnetic information may be partially or completely erased between radar scans i.e. disc revolutions. Instead of magneto-optic material, electro-optic Kerr effect material may be coated on the disc and subjected to an electric field.

Title: Improvements in razors
IPC: B26B21/32
Filed: 1929-09-20
Abstract: 327,372. Segal, H. R. Sept. 20. 1929. Razors, safety. In a safety razor of the clamped blade type, the blade is detachable from the razor without the necessity for detaching the razor parts. For this purpose, the blade has a central opening adequate for the passage of the clamping plate 7 when in the extended position, Fig. 1. The opening also renders the blade transversely flexible. The razor comprises a plate 7 pivotally mounted on a rod 12 which is slidable in a barrel 16 associated with a guard 5. The rod is threaded at its lower end to engage a nut 19 which has a bushing 18 so as to be rotatable relative to the barrel but frictionally held in engagement with it. The rod 12 carires a spring pressed pin 15, the reduced end portion 21 of which engages a sleeve 20, the intermediate por. tion being constrained, upon axial movement of the sleeve, to follow a path determined by a slot 17 in the barrel 16. The guard carries the usual aligning-studs 9 which may engage recesses or holes 8 in the plate. After using the razor, the blade is removed by sliding the sleeve 20 towards the guard until the pins 9 are free, the movement of the plate is vertical, the slot F7 being longitudinal. The slot is thereafter curved along a tangential path so that rotary movement is imparted to the plate. The plate is weighted at one end and finally takes up the position shown in Fig. 1, when the blade may be passed over it. In the reverse operation, for closing, the plate is deflected from the guard by a cam-like member 23 thereon, and the blade is finally tensioned by the nut 19. The razor may if desired be dismantled by withdrawing the nut 19 and by pressing the pin 15 into an inoperative position, when the rod 12 may be pulled completely from the razor.
