Title: Compressed-air capsule projector
IPC: F41B11/51
Filed: 1975-09-16
Abstract: 1471015 Pneumatic gun R P SCHERER Ltd 16 Sept 1975 [16 Sept 1974] 40297/74 Heading F3C A compressed air gun has a cocking lever 8, Fig. 1 and 2, for stressing energy-storing means, a trigger 9 for releasing the stored energy thereby to generate compressed air for ejecting a capsule 38 from a barrel 5 of the gun, a magazine 3 for capsules, a loading member 7 operated by the cocking lever for feeding a capsule into the barrel and interlocking means for preventing the operating of the trigger and/or opening of the magazine during operation of the cocking lever. The cocking lever 8 is fast with a shaft 13 which is rotatable about an axis 11. The energy-storing means is a compression spring 44 which, when the cocking lever 8 is pivoted, is compressed via push rods 12 and a yoke 41 which presses against a shoulder 42 of a sleeve 43, the latter housing the spring 44 and being located in a cylinder 6. The interlocking means comprises a cam 15, Fig. 3, which is fast with the shaft 13 and has a slot 16 therein which receives a pin 49 of a lever 50 pivoted at 51. During the first 16� degrees of pivoting of the cocking lever 8 in the clockwise direction, end portion 17 of the cam slot 16 moves the pin 49, pivoting the lever 50 clockwise so that a fork 52 on the lever advances a slide 53 and prevents movement of the trigger. The same action causes a hook 54 of the lever 50 to engage in a cam 55 fixed to the magazine cover 4 so that the latter cannot be opened. These actions are completed before a cam 20, Fig. 2, begins to retract the plunger 7. To fill the magazine 3, the plunger 7 must be manually retracted, a magazine cover 4 being pivoted to its open position whereupon a cam lobe 58, Fig. 3, on the cam 55 will engage an arm 59 of latch 56 so as to disengage the latter. Normally, retraction is prevented by the latch 56 which is pivoted at 51 and is spring- loaded into engagement with a notch in slider 28. An arm 57 on the lever 50 retracts the latch 56 during the initial movement of the cocking lever, so that the latter can then retract the plunger. The capsules are packed in a protective tube which is inserted into the magazine with the capsules and is then withdrawn, leaving the capsules in the magazine. The protective tube pushes magazine platform 39, Fig. 2, into engagement with a spring-loaded latch 60 engaging a transverse bar 61 attached to the platform. The protective tube is removed. The latch 60 is automatically released when the cocking lever 8 is operated. A rachet mechanism (not shown) may be provided to prevent return movement of the cocking lever until it has completed its cocking movement about the axis 11, Fig. 1, to compress the spring 44, Fig. 2. When the trigger 9 is pulled a detent ring 46 is released from a detent 47 and the sleeve 43 is allowed to move. The energy stored in the spring 44 compresses air in the cylinder 6, this air being passed into the gun barrel 5, via a passage 48, expels the capsule 38.

Abstract: 1,188,327. Extension die-heads. NATIONAL-STANDARD CO. 4 Sept., 1967 [14 Oct., 1966], No. 40362/67. Heading B5A. A replaceable die plate 9 of an extruder, particularly intended for the production of tyre tread stock, is removable from its position abutting die-head plates 12, 13 when a frame 17 supporting clamping plate 23 is swung from the position shown in Fig. 4 to that shown in Fig. 1. A latch 40, Fig. 4, is pivotally mounted on shaft 42 between lever members 43 and 44, Fig. 1, keyed to a crank shaft 50. When frame 17 is in the Fig. 4 position, shaft 50 is manually rotated to bring hooked end 54 of latch 40 into engagement with an adjustable eccentrically mounted pin 34. Clamping plate 23, pivoted on a shaft 25, pressingly engages die plate 9 by means of surfaces 60, 62 when latch 40 is closed and the parts may be locked due to the overcentre relationship between shafts 42 and 50. A lever 30 mounted on clamping plate 23 engages a spring-biased plunger 32 and allows predetermined positioning and yielding movement of the clamping plate.

The lifting member comprises a cylindrical guide 33 with a cylinder 35 movable therein. The cylinder has mounted at the upper end thereof three bearing plates 43, 45, 50 to support a rotatable shaft 44, the lower end of which is in engagement with a piston-rod 38 of a pneumatic ram 36 mounted on the guide 33 whereby the cylinder 35 and the shaft 44 may be raised and lowered. The extremities of the vertical movement of the cylinder 35 are controlled by an arm 55 mounted on the cylinder and engaging end stops 57, 59. The chamber 46 formed between a pair of bearing plates 43, 45 houses a vane (60), Fig. 4 (not shown), secured to the shaft 44 to divide the chamber into compartments (64), (65) each supplied with air from a respective conduit (66), (67) to cause the shaft 44 and hence the transfer arm 14 to rotate in the desired direction. The chamber 48 formed between bearing plates 45, 50 is filled with a viscous fluid to damp the rotary motion of the transfer arm. The extremities of the rotary motion of the transfer arm are controlled by a projection (69), Fig. 5 (not shown) mounted on a sleeve 53 secured to the shaft 44 and end stops 70. The transfer arm 14 is slidingly mounted within a guide 80 fixed to the lifting member 11. A pneumatic cylinder 82 is also fixed to the lifting member 11, but is housed within the transfer arm 14 and itself houses a piston 83 and piston-rod 84 secured to the arm 14. Conduits 86, 87 supply air to opposed sides of the piston 83 to move the arm 14 in the desired direction. The guide 80 in conjunction with end stops 90, 91 limit the movement of the arm 14. Secured to one end of the arm 14 is a bearing 106 for a shaft 105 with a vane 125 secured thereto for rotation within a chamber (124), Fig. 9 (not shown), Air is supplied on opposite sides of the vane to effect rotation of the shaft 105 in the desired direction about a horizontal axis.

IPC: A01D34/535
Filed: 1965-09-28
Abstract: A mounting arrangement for flails on a forage harvester comprises a hollow, apertured, rotor shaft which receives holders each comprising a pair of J-shaped members arranged back to back with their arcuate end-flanges passing through the apertures and engaging the inner surface of shaft, the outer ends of the J-shaped members extending radially outwardly of the shaft and pivotally carrying the flails at their outer ends, intermediate portions of the J-shaped members being interconnected by a nut and bolt which can be tightened to force the members towards one another and to cause the end-flanges to bite against the inner surface of the shaft and to co-operate with abutments on the members which correspondingly grip the outer surface of the shaft. The apertures are circular and of a larger diameter than the end-flanges so that the latter can be passed through the apertures.  The abutments are formed by notches in the straight portions of the J-shaped members of slightly greater width than the wallthickness of the shaft so that the latter can be accommodated within the notch in the vicinity of each aperture. Washers are mounted between the J-shaped members where the bolt passes through them.  The outer ends of the members carry pivot-pins on which flails or knives freely swivel.

Title: Constant Speed Compensated Electronic Control Circuit
IPC: H02P7/288
Filed: 1966-09-19
Abstract: 1,164,171. Control of D.C. motors. SYBRON CORP. 19 Sept., 1966 [27 Sept., 1965], No. 41808/66. Heading H2J. An operating parameter (speed) of a D.C. motor M, e.g. driving dental apparatus, is regulated by amplifying a portion of a D.C. source selected by control means (potentiometer 68), which is biased in accordance with a second parameter (load current) so as to keep the speed substantially constant. The supply comprises A.C. rectified at 42, smoothed by capacitor 52 and voltage controlled by Zener diode 54, and is applied to the motor via reversing switches 128 and parallel connected power transistors 88, 90, which are controlled by the voltage on the foot operated slider of a potentiometer 68 amplified by a transistor 24. The voltage on potentiometer 68 is regulated by conduction of another transistor 26; at light loads this is fully conducting, but conduction is reduced by bias from a further transistor 28 as the load, detected by resistor 74, increases, thereby adjusting the control voltage so that power to the motor is increased, to maintain the speed. The load compensating circuit is inhibited during initial acceleration by capacitors 30, 130, and further capacitors 32, 64 filter ripple feedback from the motor. A switch 34 coupled to the foot pedal opens the motor circuit directly for " stop ", to prevent run-on from energy stored in capacitor 52.
