Title: Improvements in or relating to electric ship propulsion systems
IPC: B63H23/24
Filed: 1934-04-24
Abstract: 431,603. Systems for transmitting mechanical power. GENERAL ELECTRIC CO., Ltd., and SAUNDERS, C. W., Magnet House, Kingsway, London. April 24, 1934, No. 12357. [Class 38 (iv)] In electric ship propulsion systems in which an A.C. generator supplies power to a synchronous motor the speed of which is controlled by varying the speed at which the generator is driven, increase of generator speed is accompanied by increase of excitation of the motor or generator or both. In the arrangement shown, the main speed control wheel 1 of the prime mover is coupled to a rheostat 2 connected in series with a field winding 4 in such a way that the wheel 1 makes two revolutions for each revolution of the rheostat arm 11. During the first revolution, while the motor is started and pulled into synchronism, a cam closes switch 7 whereby winding 5 is energized and closes contacts 6, thus cutting the rheostat out of the exciting circuit. The rheostat arm 11 then moves from 14 to 15 in a clockwise direction. During the second revolution of the controller, the system attains full speed, the rheostat arm 11 moving clockwise from 15 to 14. At the beginning of this period switch 7 is opened, thereby opening contacts 6 and inserting the whole of the rheostat into the circuit. Further movement of the arm 11 gradually cuts out all the resistance. To prevent the motor from falling out of synchronism, the rheostat may be cut out by the energization of winding 5 by a stability relay 8 or by closing switch 10 by hand in response to a warning signal operated by the stability relay. Specification 352,615 is referred to.

Title: Transfer Device for Woodworking Machines
Inventor: BUCKLEY ROBERT HOWARD
IPC: B27M1/08
Filed: 1967-03-17
Abstract: 1,168,502. Conveyers for timber. THOMAS ROBINSON & SON Ltd., and R. H. BUCKLEY. 25 March, 1968 [17 March, 1967], No. 12632/67. Heading B8A. In a timber transfer device used, for example, between a longitudinally-fed moulder and a tenoning and boring machine, timber lengths 19 from the moulder (not shown) pass through a tiering device 20 and, after actuating switches 28, drop on to a driven rollerway 14, 15. The switches cause dogged chains 29 to move in a direction 34 so that a timber length, now at position 100, moves laterally out of the path of the next successive timber length, as well as longitudinally towards a fair-ending fence 25 having a gate section 38. In normal operation, each timber length, on abutting the fence 25, is carried by a multi-belt conveyer 44 to a pick-up station provided with switch-operating members 48. The pick-up station includes pick-up arms 58, 59, the arm 59 being adjustable along a shaft 51 according to the longitudinal dimensions of the timber lengths. For gripping the lengths one of a pair of grip plates 64 is movable axially by a ram 65. Upon arrival at the pick-up station a timber length actuates the associated switches 45, 48 the length is gripped and, by means of a ram 80 whose operation is initiated by a dogged-chain conveyer 49, the pick-up arms 58, 59 are rotated through 180 degrees and the timber length deposited on the conveyer 49. The pick-up arms then return, through 180 degrees to their original position. An adjustable lost motion cam 81 permits the timber length, during its transfer in the arms 58, 59, to be turned over as necessary, to ensure that any desired face thereof is uppermost. The conveyer 49 may feed a double-ended tenoning cut-off and boring machine (not shown). If there is a build up of timber lengths in front of the pick-up device, a series of switches 41, if simultaneously actuated by the lengths for a continuous period, cause the gate section 38 of the fence 25 to swing to its inoperative position and excess-lengths such as the length 50 are withdrawn by escape rollers 42, 43 to a receiver or a second transfer device. The illustrated device is supported on wheels 12 and rails 13 and may be locked in position.

IPC: G21C3/08
Filed: 1961-04-10
Abstract: 1,005,711. Nuclear fuel elements. NUCLEAR POWER PLANT CO. Ltd., and A.E.I.-JOHN THOMPSON NUCLEAR ENERGY CO. Ltd., [trading as NUCLEAR POWER GROUP]. April 10, 1962 [April 10, 1961], No. 12776/61. Heading G4C. A nuclear reactor fuel element of the type in which nuclear fuel is housed in a container has the fuel and container of bar form and the container provided with fins on at least two opposed faces, the fins being located at an angle with respect to the longitudinal axis of the element. The term " bar " is used to describe a shape having a cross-section which is generally rectangular, including elliptical, in other words a cross-section which has in effect a first pair of opposed faces and a second pair shorter in length than the first. In one form (Fig. 1a) the element comprises nuclear fuel 1 in a container 2 with fins 4 on the two broader faces only and it extends across substantially the whole of a bore 3, coolant vortices R being set up on either side of the element. Where a more pronounced gap is left between the edges of the element and the wall of the bore, vortices can be promoted along the edges of the element, especially if the edges are finned. Baffles may extend longitudinally of the element to intersect the flow channels formed between the fins and divide the bore into separate channels in each of which a coolant vortex is formed. A similar effect can be achieved by arranging the fins in " herring- bone " or " chevron " formation. The element shown in Fig. 5a has the fins 4 as arranged, a pronounced gap being left between the edges of the fins and the wall of the bore 3 to provide for freer access to the flow channels. The element is supported by protrusions 2a on the container 2 which fit into the grooves in the wall of the bore 3. The bore 3 is of " clover leaf crosssection to assist in the formation of coolant vortices R.
