Title: Sheet cutting apparatus
IPC: B26D1/20
Filed: 1971-04-19
Abstract: 1343068 Cutting sheet RICOH KK 19 April 1971 [30 April 1970] 25974/71 Heading B4B Apparatus for cutting sheet material S comprises a disc-shaped cutter 2 on a shaft 3 supported by an endless belt 4, and means for driving the belt 4 so that the cutter 2 is drawn across the sheet feed path to cut the sheet S in co-operation with a bar 1. To initiate cutting, a stop 25 is released from engagement with a projection 10a of a belt supporting pulley 10, Fig. 4, a supporting shaft 13 then rotating under the action of a spiral spring 16 to drive the belt 4, so that the cutter 2, spring urged against the bar 1, is drawn across the sheet S. As the shaft 13 rotates, a member 21 attached thereto rotates in a direction a, Fig. 5A, until it strikes a blade 20b of a member 20, rotatable on a boss 19a of a gear-wheel 19, a blade 20a of the member 20 thus rotating out of contact with a projection 27a mounted on a pin 28 on the gear-wheel 19. The projection 27a thus rises from engagement with a switch actuator 29a, and an electric motor is actuated by the switch 29 to drive the gear-wheel 19 through a further wheel 24. The shaft 13 and members 20, 21 continue rotation under the action of the spring 16 until the blade 20a of the member 20 contacts a stop 26 on the gear-wheel 19, the members 13, 19, 20, 21 and 26 thus rotating in unison. At the end of the cutting stroke, rotation of the shaft 13 and member 21 is halted by re-engagement of the stop 25 and projection 10a. Rotation of the gear-wheel 19 and the attached spring casing 17 continues, thus winding up the spring 16 for the next cutting operation, until the member 21 is engaged by the blade 20b, thus preventing further movement of the stop 26 in engagement with the blade 20a. Simultaneously, the blade 20a, projection 27a, and actuator 29a re-engage, the drive to the gear-wheel 19 being cut off in readiness for a further cutting stroke. Provision of a locking panel 30 or (113), Figs. 8-9 (not shown), e.g. of synthetic material, prevents rotation of the gear-wheel 19 relative to the shaft 13 under the action of the spring 16. Control.-The stop 25 may be mounted on a lever (31), Fig. 6 (not shown), pivotable by means of an electromagnet (35) acting against a spring (33), a rotary cam (38) actuating the electromagnet (35) in a required sequence. Further, Fig. 7 (not shown), a switch actuated by movement of the cutter 2 may be incorporated in the control circuit.
Patent GB-260028-A (GB)
IPC: B21J13/08
Abstract: 260,028. Salerni, P. M. July 16, 1925. Cutlery and like blades.-A hammer for forging steel for razor blades &c. is formed with a series of projections spaced apart in the direction of movement between the work and the hammer, and the work is moved relatively to the hammer so as to receive spaced blows on various areas followed by blows on adjoining or overlapping areas so as to produce a knotting, effect on the metal. Preferably the blows are delivered in three orders, the first spaced apart, the second covering the spaces between the first blows, and the third overlapping the other two. The strip A is drawn from a furnace B and moved stepwise between the hammer C and anvil D by feed wheels E, the face of the hammer C and preferably of the anvil D also being formed with projections C', D'. The spaces C<2>, D<2> between the first and second projections are twice the width of the projections and the next spaces C<3> D<3> are one and a half times the width of the projections. After each blow of the hammer they strip is fed forward a distance twice the width of the projections, with the result that series of blows are delivered to the strip in the three orders set out above. The same result may be obtained by varying the widths of the projections and spacing them equally or by making the spaces equal and the widths of the projections equal and varying the amount of the feed between the blows. Fig. 6 shows a self-setting anvil for equalizing the blows on the two sides of the strip, the curved bottom part D<2> of the anvil D resting on the curved face of the bed D<3> and being located by means of curved slots D<4> and pins D<5>.

Abstract: 1,022,354. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 6, 1963 [July 16, 1962], No. 27303/62. Heading G6C. In a boiling water reactor the water passes through fuel channels to produce steam which gives up heat to a heat-exchanger within the pressure vessel, and the condensate returns down the outsides of the fuel channels, being heated by conduction through the walls of the channels so that it reaches the inlets of the fuel channels near saturation temperature. In Fig. 2 water rises through fuel channels 6A by forced and natural convection to the tops of the channels where part of the water forms steam which rises to chamber 11A. The steam flow passes around upper baffles 10A and over a heat-exchanger 2A; the condensate in compartment 13A together with water unconverted to steam at the tops of the fuel channels passes to a pump 17, a valve (not shown) being provided to regulate the relative flows of sub-cooled condensate and recirculation water. From the pump the water passes to a chamber 4A and then down the outsides of the fuel channels to the fuel channel inlets, the water being heated, principally by conduction through the channel walls, to reach the inlets at near saturation temperature. In a modification, Fig. 1 (not shown), separate pumps are used to deliver water to chamber 4A from compartment13A and from the bottom of chamber 11A and the relative flows are adjusted by speed control of the pumps, which may be manual or automatic in accordance with a temperature measurement at the inlet to channels 6A. In a further modification, Fig. 3 (not shown), there is no water flow from the bottom of chamber 11A. Fig. 4 shows an arrangement similar to that of Fig. 3 with the additional feature that a heat-exchanger 19 is provided inside the skirt 5C; baffles 20 are arranged so that water passing downwards from chamber 4C passes alternately around the  fuel channels 6C and around the heat-exchanger 19. The heat-exchanger 19 can form the economizer section of the heat-exchanger 2C.
