Title: Improvements in or relating to a machine tool change-speed gear
IPC: F16H61/02
Filed: 1946-06-12
Abstract: 626,468. Facilitating speed-change; friction clutches. WARNER & SWASEY CO. June 12, 1946, No. 17633. Convention date, June 14, 1945. [Class 80 (ii)] To facilitate changing mesh of sliding-wheels 23, 33, 36 in a 12-speed drive from an input shaft 13 to the work-spindle 12 of a lathe whilst the main input friction-clutch 17 is disengaged, the gear is driven slowly forwards through a planetary inching train, introduced by applying a controllable band brake 59 to a reaction ring-gear 45 meshing the smaller planets 49 of stepped planets 48, 49, on a freely-mounted carrier 46, the planets 49 also meshing a sun 43 fast on the input shaft 13, whilst the larger planets 48 mesh a second ring- gear 44 drivingly connected to a freely-mounted output pinion 52 driving the first-motion shaft 22 of the change-speed gear. A second bandbrake 57 can be applied to the planet-carrier 46 for a working reverse, whilst a third brake 58 on the output ring-gear 44 provides spindlebraking. The brake-bands are each contracted into engagement by fluid-pressure acting on a pair of opposed pistons 61. The main-clutch 17, also fluid-pressure actuated, is contained within its rotating actuating cylinder 17 and comprises a piston friction-disc 19, splined to the continuously rotating input shaft 13 and moved axially by fluid-pressure to engage a friction-disc 16 fast to a freely-mounted pinion 15, constantly meshing a wheel 21 fast on the first-motion shaft 22 of the change-speed gear. Control is by a manuallyoperated rotary distributing-valve 68, movement of which to the position C applies the brake 59 to hold the ring-gear 45 for a forward inching drive. In position R, the selector-valve applies the brake 57 alone, holding the planet-carrier 46 for a working reverse. In position B, the selectorvalve applies the brake 58 alone, bringing the gear to rest. In each of these three positions the main-clutch cylinder 17 is exhausted to release the clutch. In a further position F, the mainclutch is engaged and all the brakes released, whilst in a further position N, the pressure feed 67 from a supply-pump 64 is exhausted, giving neutral. Specification 477,439 is referred to. The Specification as open to inspection under Sect. 91 also refers to U.S.A. Specification 2,068,552. This reference does not appear in the Specification as accepted.

Abstract: 1462100 Controlling light INTERNATIONAL BUSINESS MACHINES CORP 25 April 1974 [18 June 1973] 18052/74 Heading G2F A variably birefringent assembly which together with a subsequent analyzer provides a variable spectral bandpass to incident plane polarized light comprises a stack of spaced transparent electrodes 2, 4, 6, 8 interleaved with ferro-electric layers 3, 7 exhibiting electrically controllable birefringence for example PLZT, and a transparent insulating layer 5, each of layers 2-8 being deposited in turn by sputtering or chemical vapour deposition on a glass or mica substrate 1. A further stock 9 may be mounted on the other side of substrate 1. In a modification, Fig. 6B (not shown), layer 5 is replaced with a further ferro-electric layer, i.e. electrodes are common to two ferro-electric layers. Additional ferro-electric layers may be provided, depending on the spectral range over which the assembly is required to operate. The electrodes are 500-1500 thick, and layer 5 0À2-0À5Á. The ferro-electric layers are each typically 8Á thick and are preferably formed of successive layers #1Á thick. In use selected ferro-electric layers are switched to selected ones of plurality (e.g. three) of predetermined ferro-electric states having different amounts of remanent birefringence to provide the required bandpass. The incident light may be derived from an image on a cathode ray tube and a polarizer, Fig. 10 (not shown), so that a multicolour display may be provided. In an optical storage arrangement, Figs. 11 and 12 (not shown), one of the electrodes adjacent each ferro-electric layer comprises a photo-conductive member between a conductor and the layer. The assembly is scanned by a collimated beam for writing or erasing while appropriately adjusting the polarity and level of voltages applied between the conductor and other electrodes associated with each ferro-electric layer. As particularly described there are five ferroelectric layers of PLZT, each capable of assuming three different remanent birefringent levels or zero birefringence, so that a value of from 0 to 15 may be stored at each location. A final dielectric layer acting as the analyzer is disposed at the end of the stack.
