Title: Improvements relating to electromagnetic recording apparatus
Inventor: DALTON JOHN WILLIAM
IPC: G11B5/55
Filed: 1950-03-13
Abstract: 679,938. Magnetic recording apparatus. BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION. March 13, 1951. [March 13, 1950] No. 6280/50. Class 40 (ii). [Also in Group XIX] Magnetic recording heads 23, 24, Fig. 5, each comprising a loop of magnetic material 26 with a gap 28 and a coil 27 are supported on a recording drum 1 and at one point on a rod 31 which is mounted in a bracket comprising arms 32, 33 pivotally supported on bolts 35, 36 on axis A,B passing through the gaps 28. The angular position of the brackets about the axis A,B is adjusted by a wing nut 37 and bolt 38 working in a slot 39, to ensure that the area of contact between each head and the drum is divided in half by the gap 28. The magnetic material 26 is tapered towards the gap 28 to give a high fluxdensity across the gap. Erasing heads 45, 46 are mounted in corresponding supports and a rod 51 engages the frameworks supporting both sets of heads to ensure that the heads are properly aligned. The drum may be in two halves 2, 3, Fig. 1, each half having three pairs of recording heads spaced around the periphery of the drum. The drum is moved axially to make successive sets of recordings, by energizing a solenoid (Fig. 2, not shown). This causes a rod to rise and a pivoted pawl on the rod rotates a cam 72 having a series of steps against which a cam follower 69 fixed to an extension 60 of the drum shaft 4 engages. The follower is held in engagement with a step on the cam by a spring 71. Thus, when the cam rotates the extension 60 and the drum are moved axially. When a series of recordings has been completed, the drum is returned to its initial position by pulling the rod 60 to the right and the cam 72 is returned to initial position by a spring. A stop is provided to limit the positions to which the cam moves.

Title: Improvements relating to tobacco-cutting machines
IPC: A24B7/02
Filed: 1950-03-23
Abstract: 678,959. Slicing tobacco. LEGG, Ltd., R., and SCHREIBER, P. Q. R. March 27, 1951 [March 23, 1950], No. 7338/50. Class28(ii). [Also in Groups I and XXIX] In a tobacco cutting machine a hand operated valve 18 controls the flow of compressed air to  start and stop the cutting movement of the holder 3 of a knife 1 and also operates a device in the holder to grip and release the knife to facilitate replacement by a sharpened knife. In Fig. 1 the machine is stationary, compressed air having passed out of the clutch 6 of the reciprocating crankshaft 5, and out of the brake cylinder 14 of the flywheel brake 10 and also out of another clutch 16 in the step-by-step drive to the usual conveyers. Compressed air also passes from between the pistons 2, allowing them to be forced together by admitted compressed air to release the knife from its holder as in Specification 678,960. Starting.-Handle 26 is pushed to the right whereby compressed air on the outer faces of pistons 2 exhausts by pipe 24 through air release port 28 of main valve 18. At the same time, compressed air from main supply 20 passes by pipe 30 to the space between the pistons 2 which as in Specification 678,960 grips the knife. Compressed air also passes slowly through valve 36 into clutch 6, forcing back its spring pressed piston to engage the clutch so that the crankshaft 5 is rotated to reciprocate the knife 1. The clutch 16 is similarly engaged slowly to start the step-by-step feed conveyers and the brake 10 is similarly disengaged from the flywheel 9. To stop the machine the handle 26 is pulled to the left when the brake is applied at once and the clutches 6 and 16 are opened at once. The knife is released slowly, only after the crankshaft &c. is stopped, by a delay action valve 3b shown in Fig. 3 in which a ball valve 38 is prevented from completely closing its conical seat 40 by means of a collar on the stem 46 engaging a stop-flange 44 to hold the ball 38 up a little. The valve 36 similarly allows the clutches 6 and 16 to engage slowly and only after the knife 1 has been fully clamped in its holder. If a foreign body is seen in the tobacco in the feed conveyers a subsidiary hand operated control valve allows the conveyer clutch 16 to be disengaged. For cleaning or inspection of the machine when stationary to allow the machine to be turned over by hand, the brake 10 can be disengaged. In this operation air from another hand opened auxiliary valve 50 displaces a piston 52, 54 so cutting off the exhaust of air from pipe 32 to the brake cylinder 14. When 50 is hard closed the piston 52 returns and air is exhausted from 14 allowing the brake 10 to be re-applied by the spring 12. Pressure may be applied to consolidate the tobacco between the conveyers as described in Specification 678,961, [Group I], and diagrammatically shown on Fig. 1 in which a double action piston in a cylinder 53 is connected by a hand operated valve 55 to a large air reservoir 56.
