Title: Combination of a calculating machine for all four rules with a card perforating machine
IPC: G06C11/08
Filed: 1928-12-27
Abstract: 310,362. Rheinische Metallwaarenund Maschinenfabrik S÷mmerda Akt.-Ges. April 24, 1928, [Convention date]. Addition to 301,312. Multiplying-apparatus; statistical-apparatus.- The number of key-controlling magnets in the calculating-machine connected with a card-perforating and reading apparatus as described in the parent Specification, is reduced by providing the multiplier keys only, with the controlling magnets. Thus as shown in the Figure the staggered magnets 5 of the multiplier keys 4 serving also as machine release keys are connected with the brushes and by setting up on the multiplicand keys a constant factor such as a price, a series of multiplications may be performed by feeding the perforated cards in succession under the brushes.

Abstract: 1,094,622. Measuring speed electrically. S. SMITH & SONS (ENGLAND) Ltd. Sept. 6, 1965 [Sept.23, 1964; May 4, 1965], Nos. 38826/64 and 18786/65. Heading G1N. The speed of a motor vehicle is measured by driving an A. C. tachometer generator 10 from the vehicle gear-box and applying its output between base and emitter of a transistor TR1 so that at a point during each cycle the transistor will conduct and pass a current pulse from the vehicles battery connected at 11, 12 through the primary of a saturable transformer W1, W2. The output pulses, which are of substantially constant amplitude, and of frequency dependent upon the speed of the tachometer generator are applied through transistor TR2 to a meter 13 which gives an integrated reading. A bias winding W3 on the saturable transformer compensates for changes in pulse width due to changes in battery voltage. This winding may be omitted, Fig. 1 (not shown). In a modification, Fig. 3 (not shown) the compensating bias is effected by shunting transistor TB1 with a resistor to provide a standing current in winding W1, diode is connected between winding W2 and the base of transistor TR2 which is of n.p.n. type, and a temperature sensitive resistor is connected in series with the meter to compensate for changes in meter resistance with temperature.

Title: Method and apparatus for video inspection of articles of manufacture
IPC: G01N21/90
Filed: 1975-10-01
Abstract: 1520768 Video inspection of articles BALL CORP 1 Oct 1975 [1 Nov 1974] 40166/75 Heading G1A Apparatus for video inspection of articles comprises a source 21 to illuminate an article 13 and a video camera 25 for scanning it and producing for each scan line a video signal indicative of spatial rate of change of sample optical transmission characteristics; and, to produce a signal in response to a scanned defect, means, including means 39, 41 for suppressing the video signal during a predetermined segment of each scan line and also means for discriminating between defects and desired changes. A conveyer transports glass bottles 13 between semi-diffused light source 21 and camera 25. A converging lens in front of the source increases the uniformity of illumination of the bottles. A mask may be used to pass only the peripheral portion of the beam. The light may be polarized. Photo-cell 63 with LED 61 generates a signal on arrival of a bottle to momentarily activate source 21. Horizontal and vertical synch pulses from camera 25 are applied to timing circuits 39 and 41 generating blanking pulses so as to mask the picture electronically to a rectangle or circular shape of adjustable size. Delay circuit 43 filters out signals representing slow changes. Circuit 45 gives a weighted running average of the signal during one line. Provided that the defect lasts more than a predetermined time, this is compared with the output of circuit 43 to give a pulse, to the duration of which the charge on capacitor (204), Fig. 7 (not shown) is proportional. If this charge exceeds a reference a defect pulse is generated. Edge video clipper circuit 49 sends a negative spiked pulse for each dark spot to edge remover circuit 47, which suppresses the first and last of these pulses, and to logic circuit 57 which, provided there is an output from photo-cell 63, causing a pulse from bottle detector circuit 59, produces a reject signal to reject driver 65 actuating solenoid 67 of a reject gate. Circuit 59 includes a classifying circuit which provides a reject signal when a predetermined number of defects occur in a selected number of scan lines. Details of the components and working of the individual circuits making up the arrangement of Fig. 3 are given.

Abstract: 1444374 Form, fill and seal apparatus BRITISH CELLOPHANE Ltd 23 Aug 1974 [24 Aug 1973] 40324/73 Heading B8C [Also in Division B5] Apparatus for simultaneously heat sealing and intermittently drawing-on a heat sealable sheet material from a supply source, comprises a pair of heat seal jaws 7, a mechanism for cyclically closing the jaws 7 upon the sheet material, moving the closed jaws in a direction away from the supply source so as to draw a predetermined length of the sheet material from the supply source at the same time as heat sealing the sheet material, opening the jaws and returning the jaws to their original position, and two pads 20 (or 22, 22<SP>1</SP>), one associated with each jaw 7, adjacent to and movable with the jaws and capable of applying a grip to the sheet material at a position prior to its entering between the jaws 7 during the period the jaws are in the closed position. In a form, fill and seal packaging apparatus, Fig. 1, a web of sheet material 2, e.g. heat-seal coated cellulose film or heat-sealable polypropylene film, is shaped into a tube 4, by a former 1 and longitudinally heat sealed by a reciprocable bar 5 pressed against a filling tube 9 during rest periods in the intermittent downward movement of the sheet 2. A transverse seal 12 is effected by the jaws 7 which descend in closed position through a predetermined bag-length distance and simultaneously, a charge of merchandise 8 is introduced through the tube 9. At the bottom of the movement, a knive 11 in one jaw 7 cuts centrally through the seal 12. Preferably, the metal jaws 7 are serrated to provide a crimp seal. In one embodiment, Fig. 2, rubber strip pads 20 are mounted on members 16 slidable by rods 17 on brackets 15 on the jaws 7 and urged outwardly by springs 18. Nuts 19 are adjustable to ensure the outer edge of each pad 20 projects beyond the jaw face. During the draw-down movement of the jaws 7, the pads 20 provide a substantial portion of the traction applied to the tube 6. In another embodiment, Fig. 5, offset pads 22, 22<SP>1</SP> are provided on guide members 21 fixed to the jaws 7 so that, in the closed position of jaws 7, the tube 6 follows a sinuous path. In a further embodiment, Fig. 6, similar to that of Fig. 2, the pads 20<SP>1</SP> and the members 16 are shorter than the jaws 7. The pads 20<SP>1</SP> comprise an electric current conducting silicon rubber secured to the earthed members 16 by electric current conducting cement to discharge any electrostatic charges if the tube 6 is made of, for example, polypropylene. The member 16 of the right-hand jaw 7 is mounted on an arm 23 pivoted at 24 and urged to the full-line position by a spring 25. In operation, an air cylinder 27 holds this pad 20<SP>1</SP> against the other pad 20<SP>1</SP>. On malfunction of the apparatus, air is withdrawn from the cylinder 27 to separate the pads 20<SP>1</SP> and prevent static electricity being induced in the tube 6. In a modification (not shown) both pads are mounted in a manner similar to the right hand pad of Fig. 6.
