Title: Improvements in or relating to Overload Clutches
Inventor: SCOTT THOMAS VINCENT
IPC: F16D43/22
Filed: 1967-01-14
Abstract: 1,151,632. Overload release clutches. MORGAN FAIREST Ltd. 8 Jan., 1968 [14 Jan., 1967], No. 2091/67. Heading F2C. An overload-release positive clutch permitting a high starting torque but centrifugally adjusting to provide overload release at a lower running torque between a pulley 2, or sprocket, belt, or chain, driven from an electric motor (not shown), and a driven hub 3 in a bottle labelling machine, comprises a two-armed lever 12, 22, pivoted at 11 on the pulley 2, the lever arm 12 having a greater turning moment about the pivot 11 than the lever arm 22 and being accommodated in a gap 9, between the face of the pulley 2 and a spaced flange 8 of the driven hub 3, and carrying a projecting pin 13 on which is journalled a roller 14 which, during drive, engages a notch 10 in the periphery of the driven hub flange 8, the roller 14 being urged into the notch 10 by an adjustably spring loaded rod 16 connected to the outer end of the lever arm 12 such that overload release of the roller is ineffective on machine starting to permit high torque transmission but as the normal running speed is attained the lever arm 12 centrifugally overcomes the combined effect of the lower centrifugal loading of the lever arm 22 and the spring-loaded rod 16 to partially disengage the roller (as shown dotted at 14X) in which position overload release of the roller at a lower torque than that required on starting, is readily effected, the roller pin 13 carrying an extension 23 which, when the roller moves radially outwards on overload release, engages a micro-switch 24 to switch off the electric driving motor.

Abstract: 1,152,882. Perforating film and sheet material; laminates. G. ASHWORTH. 16 Jan., 1967, No. 2193/67. Headings B5A, B5B and B5N. [Also. in Divisions C1 and D1] Thermoplastic sheet material, including woven fabrics, and films, is perforated by the action of fluid jets having a temperature at or above the softening point of the material and a supply pressure of at least 100 p.s.i. The thermoplastic material may be, for example, P.V.C., a polyolefine, a polyester, a polyamide. or an A.B.S. copolymer and may exist, as a single layer or a layer backed by e.g. a fabric or a paper layer. In one embodiment (see Fig. 1, not shown) shee material is passed over a heated roller and then over a cooled roller, jets of fluid from intermittently fed perforated stationary tubes being directed on to the sheet as it passes between the rollers. In a second embodiment (see Fig. 2, not shown) the jets are produced by a series of continuously fed perforated tubes mounted about the periphery of a rotating drum, the jet being directed against the sheet through a cover member having an elongated slot. In a third embodiment a continuously fed longitudinally perforated tube, inside which one of the rotating vanes which periodically cover and close the perforations, is used. The fluid may be a gas such as air, a vapour such as steam, a liquid such as a low viscosity oil or water, or a mixture of these.

Title: Improvements in or relating to inserted blade cutters
IPC: B23C5/24
Filed: 1941-02-18
Abstract: 547,230. Milling-cutters. MILLER, F. P., and DORNHOFFER, E. G. Feb. 18, 1941, No. 2203. [Class 83 (iii)] A rotary or other type of inserted blade cutter has the blades locked by wedges, Fig. 7, which are slotted at 28 to permit the lateral insertion of operating screws 30 so that the wedge is moved positively in both directions of movement. The cutting body 18 Fig. 2, has radial blade receiving slots 19 the bottom of which are preferably inclined as shown so that both radial and axial adjustment of the blades 22 may be effected by backing-up screws 23 which also serve to prevent axial blade movement. The blades are of rectangular section and are locked by wedges 24 engaging in corresponding sockets 25. The wedges are substantially cylindrical with inclined bearing faces 26 and the slots 28 are rounded at the inner end and serve to guide the head 31 of the operating screw. The top of the wedge is bored out at 34 so that a wrench 33, Fig. 3, may be inserted to tighten the screw into a threaded hole in the cutter body thus forcing the wedge towards and clamping the blade. In a modification Figs. 12 and 13 the blades 221 have stepped leading surfaces which are provided with serrations 35 which increase in depth upwards from the bottom of the blade. The wedge, Fig. 13, has serrations of complementary form. In this form positive axial locking of the blades is obtained. In another modification the blades have serrations on the leading face which decrease in depth upwardly from the bottom of the cutter to engage corresponding serrations on the wedge. In this form the trailing face of the blade, Fig. 16, has horizontal serrations engaging corresponding serrations in the body. In a further modification the wedges may be provided with constant depth serrations, such wedges being adapted for use with either of the blades shown in Figs. 12 and 16.

Title: Improvements in or relating to cinematographic apparatus having a device for the automatic hooking of a film on a receiving spool
IPC: G03B1/56
Filed: 1961-01-19
Abstract: 968,690. Film threading. PAILLARD S. A. Jan. 19, 1961 [Jan. 19, 1960], No. 2244/61. Heading G2E. Film is latched in the slotted hub of a take-up spool in kinematographic apparatus by means of two guide elements extending between the spool flanges one of which can engage the slot in the hub and so hold the spool to allow entry into the slot of the leading end of the film which upon striking the interior wall of the hub causes movement of the second element, this movement controlling the withdrawal of both elements from the hub slot. As shown in Fig. 1 loop-forming members 7, 8, shown in the closed (film-threading) position, are spring-urged outwards (by means not shown) for free running of the film F during normal operation, but are held as shown by means of toothed sectors 9, rigid with numbers 7, 8, engaging, one directly and one via gear 10a, a gear 10 manually rotatable by crank 11 to close the members 7, 8, the gear 10 being constrained against return rotation under the spring-urging of members 7, 8 by a pin 34 (Fig. 3). The latter extends through the plate 27 and is carried on the same member as a pin 31 which can be depressed by means of a cam 30, to cause withdrawal of pin 34 and allow members 7, 8 to open. When a movable member 19 is held in the position shown by arm 36 rigid with loop-forming member 8, a pin 14 is disposed at the upper end of slot 20 (Fig. 2) thereby allowing spring 17, bearing against a pin 18, to pivot a guide element 12 clockwise against the tension of a steel strip 16 and cause hook 15 to enter a slot in the hub of spool 2. The film F is driven by feed sprockets 3 and 4 into the slot guided also by an element 13 pivoted on a pin 22 (Fig. 3). Buckling of the film on its contact with the hub interior moves element 13 causing rotation of cam 30 to act on pin 31 and allow guides 7, 8 to open as described above. The anti-clockwise pivoting movement of guide 8 causes arm 36 to push member 19 upwards thereby pivoting guide elements 12 and 13 out of the region between the spool flanges by means of projections 21 and 25 cooperating respectively, with pins 21, 24 at either end of member 19. Specification 918, 387 is referred to.

Title: Identifying faulty address decoders belonging to functional units
IPC: G06F11/16
Filed: 1978-01-19
Abstract: A central control unit is connected via a common bus system to a number of function units, each of which being furnished with redundant address decoders in order to ensure reliable selection of the function units. If, in response to an address which is sent out by the control unit, a signal is emitted by only one of the two address decoders of a function unit, a recording is made in a memory device corresponding to that decoder to indicate an erroneous condition in one of the address decoders of the addressed function unit. If, on the other hand, signals are emitted by both address decoders a check signal is returned to the control unit, the absence of the check signal indicating that either one of the decoders belonging to the addressed function unit is faulty. Error recordings are read out from the respective memory device by subsequent addressing of the units, the read out from the memory device belonging to the one address decoder being effected by the signal emitted by the other decoder and vice versa.
