Abstract: 1378415 Web bursting apparatus BURROUGHS CORP 11 Dec 1972 [22 Dec 1971] 57052/72 Heading B4B] Apparatus for separating at pre-weakened zones items, e.g. printed forms, from a continuous web of such items comprises means 52, 54, Fig. 1, for tensioning the web in the area of the pre-weakened zone and means 76 associated with the tensioning means and displaceable relative thereto so as to cause the web to exceed its elastic limit thereby bursting the web at the pre-weakened zone. The tensioning means includes upper and lower pressure members 52, 54 formed from resilient plastics material the upper member being secured to a rail 56 fixed between side frames 68 of the apparatus. The lower member 54 is formed with a cut-out 74, Fig. 5, thereby providing two leg portions which are attached respectively to rail members 58a, and 58b, the latter rails are connected to each other by spacers 78 thereby providing a gap for a penetrator member 76. The lower member is movable in the side frames 68, Fig. 3, by means of cams 112 thereby enabling the member 54 to be pressed into contact with the upper member 52; each resilient member is provided with deformable web portions 52c, 54c respectively. In operation, the web 28 is fed by a pin-feed device 14 between both members 52, 54 until the leading end is gripped by delivery rollers 40, 42, the feed being stopped when a line of weakness is between the members 52, 54. A motor 106 is then energized so as to rotate the cams 112 thereby raising the member 54 so that it grips the web; due to the shape of the members, the web is stretched in the area between the members. At this point in the cycle, the penetrator is raised by a cam 114 thereby deforming the web portions 52c, 54c, Fig. 7 (not shown), until the web bursts at the line of weakness. The penetrator and resilient member are then lowered and the severed item (28), Fig. 8 (not shown), carried away by the delivery rollers 40, 42. In the modification shown in Fig. 11, the stretching of the web is effected by means of a member 130 having a clamping foot portion 128 and a pivoted foot member 134; the latter foot members are adapted to co-operate respectively, with a resilient block, e.g. of rubber or plastics material and a resiliently covered roller 146. A penetrator 140 effects the final bursting. In further modifications the stretching is effected by two pairs of resiliently-covered rollers 154a, 154b and 156a, 156b, Fig. 10 (not shown), rotating at different speeds and associated with a penetrator (164) which may be actuated by a rack-andpinion device, Fig. 11, (not shown); the two sets of rollers may be arranged to rotate momentarily in the reverse direction.

Title: Photoelectric guard system for machines
IPC: F16P3/14
Filed: 1971-12-13
Abstract: 1342144 Photo-electric-machine guard system CINCINNATI Inc 13 Dee 1971 [12 May 1971] 57776/71 Heading F2J [Also in Division G1] In a photo-electric guard system using the interruption of a light beam to stop a machine, the light source is modulated by modulating its current supply and the signal arising from the detection of the modulated light is compared with the modulation of the source current to effect shut down. Alternate lights of a series 14a-14g, Fig. 1, forming a protective light curtain are energized in antiphase by a square wave generator, and after shaping, the pulses from detectors 20a-20g positioned to recieve the respective modulated light beams, are applied to a comparator 26 to which the modulation from the supply current is also applied. The comparator comprises a NAND gate and produces an output pulse for each cycle of each phase if all signals-are present. The output pulses from the comparator are measured for separation and duration, for stopping the machine, and guard system muting arrangements may be incorporated to be operative for example during the up movement of a ram, together with a suitably positioned GUARD-OFF indicator. The switchoff may be actuated by overrun apparatus. False operation by metal deformity for example at the bottom of the downward stroke of a press, may also be avoided by synchronized muting. The arrangement is made fail-safe and includes limit-switch monitoring.

Abstract: 1,201,810. 810. Automatic control of current. ROBERT BOSCH G.m.b.H. Dec.21, 1967 [Dec.21, 1966], No.58208/67. Heading G3R. [Also in Division H2] A control system for a d.c. motor 10, 11, e.g. for traction comprises a semi-conductor switch (thyristor 13) for regulating the current, a control circuit 37 responsive to a reference value set on a controller 42, and a bridging contactor 19, 22 shunting the switch and controlled by a voltage dependent semi-conductor (transistor) circuit 67 connected through an integrating circuit to the output of the control circuit 37. The reference value at 42 is opposed by the voltage across a resistor 18 in series with the motor, smoothed by capacitor 64, so that the circuit 37 controls the duty ratio of thyristor 13 to keep the motor current constant, at leat during acceleration. When, as the motor nears full speed, the duty ratio approaches 100% the voltage from the integrating circuit (in 67) is sufficient to switch on the transistor circuit 67, thereby energizing 19 and closing contacts 22. Thus the motor is fully energized, but the circuit 37 continues to be activated and if, due to an increased load, the duty cycle drops, the bridging contactor is deenergized and current control re-established. The bridging contact is, however, held closed if the controller 42 is advanced to the full speed position, and also if a second integrating circuit detects very rapid switching by the circuit 37, which occurs if the motor is stalled. Rapid changes by the controller 42 in the increase current direction are delayed by RC circuit 53, 63, which is short circuited for the decrease direction by a diode 62. Motor current during "off" periods is carried by a freewheeling diode 33. The main thyristor 13 is switched off by a capacitor 26 switched by a commutating thyristor 25, 13 and 25 being triggered alternately by respective blocking oscillators 35, 36 controlled by the circuit 37. The triggering circuits 35, 36 and the control circuits 37, 67 are fully described Figs. 6 and 7 (not shown). The thyristor 13 may alternatively be a "gate controlled switch". A resistor 59 is inserted in the current feedback path when 22 is closed to compensate for the current change due to loss of voltage drops though 13.

In one embodiment, Fig. 2, the stencil blank comprises a layer 2 of polyethylene sandwiched between sheets 3, 4 of kraft paper, and the adhesive layer 5; a cover sheet 6 with release coating 7 protects the adhesive. The design pieces 8 are formed by cuts 9 extending only through layers 2 to 5. Thus, the cover sheet 6 is peeled away together with pieces 8 from the stencil just before it is adhered to a substrate; paint is then applied, and the stencil removed after the paint has dried, any adhesive being removed by washing. Alternatively, the pieces 8 can be retained on the wall and the rest of the stencil removed prior to painting; subsequently pieces 8 can be removed to leave a design on the substrate.
