Title: Data sensing device for an accounting machine
IPC: G06K7/04
Filed: 1962-09-27
Abstract: 949,445. Statistical apparatus. NATIONAL CASH REGISTER CO. Sept. 27, 1962 [Nov. 30, 1961], No. 36685/62. Heading G4M A programme tape for an accounting machine is sensed by a member which is pivotally connected to a support, the support being biased to a first position if a perforation is sensed, and being driven to and retained at a second position if no perforation is sensed. The tape is driven in synchronism with the columnar movement of the travelling carriage of the accounting machine and is perforated at selected positions to control the operations performed by the machine. One or more spring contacts 56 sense particular positions of the tape e.g. controlling the multiplying function, and when a perforation is sensed by them solenoid 129, Fig. 8 is energized to reset the support members and perform a sensing operation on another portion of the tape. Arm 100 is rotated anticlockwise and lever 127 moves reset link 114 forward so that its cam projections 120 move reset plate 115 to the left, this in turn moves slides 117 to the left so that all sensing arms 105, Fig. 2 drop back to the first position. A similar reset action is performed for sensing arms 108 by means of a linkage 125 and sliders 117a. Further movement of arm 100 causes stop 155 to release lever 127 from camming surface 156, reset link 114 springing back and sliders 117, 117a returning to abut against the ends of arms 105,108. Arm 100 then moves a slide 89 to the left, through link 99, and inclined slots in the slide 89 cause shafts 106, 109 bearing arms 105, 108 to be raised. Assuming sensing finger 110 to sense a perforation, the end 132 of arm 105 is biased downwards by a spring contact 135 to retain it in its original position while the other end pivots about the finger 110. Arm 105 returns to the horizontal when slide 89 returns to the right at the end of the sensing operation. Assuming finger 111 not to sense a perforation, end 133a of arm 108 is urged downwards as shaft 109 rises, and overcomes the bias of spring contact 135a which is thereupon moved to its upper position as shown. Slide 117a is urged to the left by a spring 122a and a shoulder on the slide latches under end 133a to retain it in the second position when shaft 109 is lowered. Thus spring 135 or 135a engages one or other of contacts 149, 141 or 149a, 141a according to whether perforation is sensed or not, and this condition is retained until the resetting operation occurs before the next sensing operation. Specifications 886,123 and 949,444 are referred to.

Title: Improvements in or relating to fluid-control valves
IPC: F16K31/56
Filed: 1959-11-02
Abstract: 891,555. Valves. GERDTS, W. F., and GERDTS, H. R., [trading as GERDTS, KOMM.-GES., G. F.]. Nov. 2, 1959 [Nov. 3, 1958], No. 37050/59. Class 135. A valve lever 18, Fig. 2, is pivoted upon stub shafts 17 by a stirrup 23 and actuated by a handle 19 through another stirrup 24 having an aperture 25, Fig. 1, through which passes the lever ; the latter, which is disposed in an outlet pipe 15 with the interposition of a spring sealing bellows 16, has its outer end abutting an adjustable toggle spring 21. Upon turning the handle 19 anti-clockwise, and after a certain lost-motion, the upper edge of the aperture 25 abuts the lever 18 and turns it in the same direction, overcoming the spring 21, which, after passing through the centre point assists the force exerted through the handle 19. The main end of the lever is thereby raised and lifts a pin 13, Fig. 3, to unseat a ball valve 11 so equalizing pressure across a main closure 6 loaded by a spring 7 ; further movement of the handle 19 unseats the closure 6 and connects a container 3 with the pipe 15 and the handle is brought into a position where it is retained by detents, not shown. The aperture 25 is so dimensioned that upon a sudden fall of pressure in the pipe 15 the main closure 6 is closed by the resulting pressure differential thereacross, the spring 21 passing through its centre point and holding the lever 18 in the valve closed position. In a modification, the compression spring 21 is replaced by a tension spring connected to the lever through a bell-crank lever mounted on the latter.

Abstract: 1,042,060. Opening containers. J. LYONS & CO. Ltd. Sept. 16, 1964 [Sept. 20. 1963], No. 37080/63. Heading B8D. A can, placed on a loading platform 2, operates a switch 21 to drive a pneumatic piston 10, thereby positioning the can below a piercer 5 which is automatically actuated to pierce both the top and bottom of the can. As the piston 10 advances, it engages a cam to actuate a main control valve. The valve causes clamping pistons (one shown at 14) to advance and hold the can on either side. Simultaneously, a piston device 3 drives the piercer 5 through the can and automatically withdraws the piercer. The liquid contents fall through a mesh screen into a trough 6. Emptied cans are pushed further along a guideway 1 until they fall into a discharge guide 12. A member 20 prevents the can from rising as the piercer withdraws.

Abstract: 896,921. Cartons and wrappers. MEAD CORPORATION. Nov. 13, 1959 [Nov. 18, 1958], No. 38649/59. Class 18. Abutting, terminal edges 12<SP>1</SP> 18<SP>1</SP> of a carton or wrapper are secured together by a shouldered tab 20 engaging a tapered slot 24<SP>1</SP>. The slot is tapered to provide at its largest width a slot through which the tab 20 is passed, and at its narrowest width a portion which engages the neck of the tab 20 and so secures the tab. The natural tendency for the carton or wrapper to regain its flat state, as well as the pressure of the contents, ensure that the tab engages the narrowest portion of the slot. The cutting of the lot simultaneously provides a tab 24 which is upstanding when the carton or wrapper is folded. When applied to a carton having corner gussets 32, the invention may be used to pack frozen foods. Flaps 36 are provided to prevent pilfering. If the corner gussets are cut obliquely as at 32<SP>1</SP> (Fig 5), blanks can be cut from a web with a minimum of waste. In an alternative form of carton, Fig. 10, a display window 128 is provided and perforated tear lines 130 extend across an adjacent panel 104 from the window. In this form, a flap 100 has cutouts 1101, 116<SP>1</SP> which form tabs 110, 116 on an adjacent blank thereby avoiding waste of material. The tab 116 of this form and a tab 26 on the previously described form act as registering tabs.
