Abstract: 426,667. Tin-openers. GRODETZKY, R., POLAK, B., GRODETZKY, R., and SCHLEISSNER, P., (trading as GRODETZKY & POLAK, [Firm of]), 31, Skretova, Prague. Dec. 2, 1933, No. 33957. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 24, 1934.] [Class 66] A tin-opener, of the type in which a supporting shield 4 provided with a pivoted cutter 5 is guided along the rim of the tin by the rolling of a toothed wheel 3 mounted on the shield, is characterized by a clamping jaw 6 arranged behind the cutter in regard to the direction of movement of the shield, which jaw, pressing against the rim of the tin as shown in dotted lines, holds the cutter on the tin. As shown, the cutter is integral with the jaw. The hole in the shield through which passes the rivet 9, which constitutes a hinge for the jaw, is provided with a recess 13 projecting beyond its circular shape, into which recess the material of the head of the rivet has been forced. The jaw is thus held fixed in a certain position when the cutter is out of use. There is a little vertical play at the hinge. To place the opener on the tin the shield is placed loosely over the rim and against an abutment 11, as shown. Pressure is then applied in the direction of the arrow 10 on the jaw, the material of the rivet occupying the recess is forced out of it, and the jaw moves to the dotted line position, clamping the shield on the tin. To cut the tin the wheel 3 is rotated by means of a handle 2, the shield moves in the direction of the arrow A, and the jaw pivots, riding down a ramp 8 and abutting a stop 7, the cutter 5 being thus plunged into the tin and positioned in the lee of the rim. In a modification, there is no vertical play at the hinge 9. In another modification the cutter 5 and jaw 6 are separate and have a common pivot on the shield, the jaw being provided with a lug which, when the jaw turns, takes the cutter with it. The appliance may be used to cut the side wall of the tin.

Abstract: 175,796. Jagger, P. B. Dec. 3, 1920. Untwisting ropes.-Relates to machines for untwisting and reeling the strands of a rope or the separate wires or group of wires of a strand. As applied to the form of machine set out in Specification 133,438, spools 3 for receiving the strands or wires are mounted on spindles 4 in carriers 5 connected to a revolving drum 6. Each spool receives an intermittent partial rotation from a ratchet-wheel 7 and pawl 8, which is connected to a link device 9 slidable in the carrier 5 and having a projecting spindle 11. Once in each revolution of the drum 6, each spindle 11 contacts with a cam 1, pivoted to a plate 2 and adjustable by a screw 13, and partly rotates the corresponding spool. After contact with the cam, the spindle 11 is returned to its normal position by a spring. A rack-and-pinion drive may be substituted for the pawl-and-ratchet wheel, and provision may be made for holding a link away from the cam. One cam suffices for a number of spools mounted in the same orbit. Any cam can be adjusted so as to vary the rotation of its spool or spools independently of the others. The strands or wires are received in confining-devices 17 driven by conducting-devices 18, and are distributed by devices 16 to the spools 3. The rope to be untwisted is taken from a roll 25 through a hollow shaft 27 and between gripping-rolls 20 which are driven by means, similar to those for rotating the spools 3, from adjustable cams 21<a>, the shaft 27 being rotated. After leaving the gripping-rolls each strand passes to its respective confining-device 17 and spool 3.

Abstract: 652,631. Feeding webs. SAPAL SOC. ANON. DES PLIEUSES AUTOMATIQUES. Dec. 29 1947, No. 34394. Convention date, March 22, 1946. [Class 100 (i)] A device for the step-by-step advance and periodical transverse cutting of a strip 5 of wrapping material in a wrapping machine is characterised by mechanism serving after each cutting operation and prior to the next advance movement automatically and positively to retract the leading part of the strip, this mechanism including means operable in timed relation to the advance movements for pressing the strip and a surface of a retracting member together, actuating means for effecting displacement of the surface of the retracting member, and means for adjusting the extent of this displacement. The strip 5 is drawn forwards by a pair of grippers 3, 4 carried by a carriage 2 which is moved to and fro in a guide 1 by means of a link 8, a lever 7 and a cam (not shown), mounted on a shaft 6. The jaws 3, 4 are biassed to closed position and may be separated by means of a lever 9 which cooperates with a mobile control member 10. The cutting is effected by cutters 11. The mechanism for retracting the strip comprises a friction roller 17 driven by a toothed sector 20 which rocks about an axle 21, and a second friction roller 22 borne by an arm 23 integral with a shaft 24. By means not shown, the shaft 24 is given an angular rocking motion so that the strip 5 is pressed between rollers 17, 22 when roller 17 is being rotated anti-clockwise, but so that roller 22 is lifted clear of the strip when roller 17 is rotated clockwise. Sector 20 is rocked by means of links 30 and 26 connected to a bell-crank lever 25 rocked by a cam (not shown), on the shaft 6. The extent of the rocking motion of the sector 20 and hence the distance through which the strip 5 is retracted is adjustable by means of a slide 27 in a link motion 28, the slope of the latter being altered by turning a screwed rod 31. The grippers 3, 4 may also carry with the strip 5 one from a pile of labels 12 carried by a support 19, the lowermost label being separated from the pile by pneumatic means (not shown), and a separating member 13.

Title: Improvements in and relating to the continuous casting of metal
IPC: B22D11/10
Filed: 1960-10-12
Abstract: 897,074. Continuous casting - machines. SCHLOEMANN A.G. Oct. 12, 1960 [Oct. 13, 1959], No. 34901/60. Class 83 (1). In a continuous casting process molten metal is fed to the chill mould from a closed container by gas pressure, the fall of pressure due to lowering of the metal in the container being compensated for by measuring the issuing casting continuously or at short intervals and raising the pressure of the gas in the container in dependence upon the issued length. The machine comprises a mould 14 which is oscillatable in, and rotatable with, a sleeve 17 mounted for rotation in bearings 18, 19. The casting is withdrawn by rollers 24a, 24b and rotates with, and at the same speed as, the mould. The actuation of a limit switch 46 by the issuing casting not only initiates the operation of a saw 47 to cut-off a length of casting, but also energizes a magnet coil 52 which advances a ratchet wheel 64 by one tooth to relieve the spring loading the ball 62 in a pressure-reducing valve 56. The equilibrium of the ball is thereby upset and pressure gas flows through the valve from the chamber 70 to the molten metal container 1 to compensate for loss of pressure therein due to the lowering of the metal level. 75 is an excess pressure relief valve. The pressure in the chamber 70 is maintained substantially constant by means of a diaphragm 80, whose movement with variation of pressure operates contacts in an electrical circuit controlling a cut-off valve 90 between the chamber 70 and a high-pressure container 78.
