Title: Improvements in and relating to commutators for dynamo-electric machines
IPC: H02K13/00
Filed: 1921-10-06
Abstract: 191,157. Hatcher, E. C. Oct. 6, 1921. Commutators; brushes and brush-holders.-A commutator has two sets of segments insulated from each other, one set forming a cylindrical brush contact surface and the other a disc surface ; or the surfaces may be inclined one to the other with one or both surfaces tapered or conical. The cylindrical segments c, Figs. 1 and 3, having connectors h are mounted on a flanged sleeve a on the shaft k and the disc segments e are placed around the segments c, insulation f being interposed. The segments e are secured by an insulated ring g, upon which a spider i is pressed by means of a screw ring j. Only one set of brushes may be in co-operation with its commutator at any particular time. To effect this, either the bracket m carrying the brush gear, or the armature is axially movable; by these means the brush p may be moved out of contact, or have its pressure varied, while the pressure on the brush o remains constant. The two commutator surfaces may be separated by an air gap, or by a band or strip of insulating material on to which the brushes o pass as they become idle. Instead of having separate brushes o, p, a single brush v, Fig. 4, may be employed. The invention is particularly applicable to machines which are required to operate alternatively as motors and as generators in starting and lighting sets for motor vehicles. According to the Provisional Specification, the two commutator surfaces may form parts of the same cone or parts of different cones of the same angularity.

Title: Improvements in or relating to Apparatus for Handling Rod-Shaped Articles.
IPC: A24C5/354
Filed: 1966-06-15
Abstract: 1,191,458. Endless conveyers; packaging cigarettes &c. MOLINS MACHINE CO. Ltd., and D. W. MOLINS. 13 June, 1967 [15 June, 1966], No. 26709/66. Headings B8A and B8C. Cigarettes are fed by a constant speed pocketed belt conveyer 18 to a faster-running smooth endless band conveyer 19. Due to transfer to a pocketed belt conveyer 20 normally running at a slower speed than the conveyer 19, the cigarettes build up at the downstream end of the conveyer 19. If the build up does not extend sufficiently upstream to prevent light passing through gaps in the cigarettes abreast of a photo-cell 27, the latter is energized and thereby causes the conveyer 19 to run at a slower speed. When, due to running at the slower speed, cigarettes back up solidly level with a photo-cell 26, the conveyer is switched back to its faster speed. When the supply of cigarettes fails to such an extent that a photo-cell 28 is energized, the conveyer 20 is stopped. By these means every pocket of the conveyer 20 is always supplied with a cigarette. The cigarettes are held to the conveyer 20 while travelling round a roller 24 by the action of suction applied through ports in discs 25 on either side of the roller 24. A row of the cigarettes is picked up from the upper run of the conveyer 20 by a suction carrier 30 and deposited layer by layer in a container 29, as the latter is stepped down by a chain 48. The carrier 30 moves parallel with the conveyer 20 until the instant of transfer, and then moves at right angles towards the container 29. The carrier 30 may also have a vertical movement relative to the conveyer 20 and container 29. The movement of the carrier 30 is generated by a linkage 42, 43, and is guided by follower 32 on the carrier 30, moving in slots 33 in cam plates 34. In modifications (Figs. 1, 2 and 6, not shown), there may be a single photo-cell with the conveyer 20 having a greater variation in speed.
