Title: Improvements in or relating to variable speed power transmission
IPC: F16H61/662
Filed: 1929-09-02
Abstract: 344,062. Variable speed gearing. HAYES, F. A., Middletown, New Jersey, U.S.A. Sept. 2, 1929, No. 38605/30. Convention date, May 7, 1929. Divided on 343,988. [Class 80 (ii).] In variable-speed gearing with torus discs engaged by precessing rollers, the rollers are supported in rockers pivoted to rock in a plane parallel to the discs. In Fig. 1, which shows a portion of the twin gear arrangement described in Specification 343,988, discs 10, 15 are engaged by precessing rollers 19 between them. Trunnion blocks 33, Fig. 4, rock on trunnions 32 in the rockers 28, and in turn carry the trunnion ends 24 of the carriers or yokes 22 of the gear rollers 19. The rockers 28 are in two parts connected by bosses 30, Fig. 5, so as to straddle the arms of a spider 25 to which they are connected by pivots 27 parallel to central shaft 12. The rockers 28 are operated to move the rollers to initiate precession by arms 34 engaging a central control ring 35. The geometry of the set is seen in Fig. 13. With the proportions shown, as the rockers 28 rock on pivots 27, the rollers 19 are moved in the line n, n, that is along the axis of rocking of the rollers 19 and carriers 22. This linear movement is combined with a turning movement about a perpendicular axis or diameter of each roller through the points of contact of the roller with the two discs. By suitably placing the trunnion blocks 33 with respect to the pivots 27, the turning movement of the rollers can be made to predominate over the linear movement. The two movements are always present more or less in combination. Specifications 344,061 and 344,066 also are referred to.

Abstract: 1304122 Automatic control systems H W ANGELERY 19 Aug 1971 [31 Aug 1970] 39034/71 Heading G3R [Also in Division H5] A control system for an electrode boiler (see Division H3-5) includes means for controlling the distances between pairs of electrodes 20 and the insertion of insulating shutters therebetween. A thermistor senses the water temperature and supplies an input signal to apparatus demand limiter 34 across terminals 77, 78. A further input is from the current supplied to the electrodes 20, inducing a current in the windings of a current transformer 80 which is applied to a rectifier 82. The rectifier output is taken from an adjustable voltage divider 84 and added in reverse series to the signal from the thermistor. The output from terminals 86, 88, stabilizes before the power demand becomes undesirably high. The boiler heats water or oil or makes steam, and a steam pressure sensor may replace the thermistor in the latter case. The output from terminals 86, 88 is supplied to a plant demand limiter, which limits the output of limiter 34 in accordance with the power demands of other equipment before the output of limiter 34 is supplied to the electro-motive unit controlling the movable electrodes and shutters.

Filed: 1961-11-03
Abstract: 978,439. Semi-conductor devices. MERCK & CO. Inc. Nov. 3, 1961 [Nov. 10, 1960], No. 39505/61. Heading H1K. A semi-conductor device comprises a silicon carbide layer lying between and ohmically fused to a graphite substrate and a silicon film. In one example, a pure graphite substrate is heated to 1500‹ C. for 5 minutes in a non- oxidizing atmosphere to remove surface contaminants, and a solution containing phosphorus pentoxide is applied to its surface. A layer of silicon 0.01 inch thick is then applied either from a solid source, or by vapour phase decomposition such as deposition on to the heated graphite substrate from a vapour mixture of trichlorosilane and hydrogen. The graphite substrate and silicon layer is then heated in an argon atmosphere to melt the silicon so that a doped silicon carbide layer forms between the graphite with a good ohmic contact to the silicon. B 2 O 3 may be used in place of P 2 O 5 .In an alternative arrangement, the doping is carried out during the melting and recrystallizing step by providing an ambient atmosphere of for example, PCl 3 or BCl 3 . Reference is made to the use of other deposits such as aluminium, gallium, indium, arsenic and antimony and their halides and oxides. A rectifier (Fig. 4) may be produced by providing a P-type region in an N-type silicon layer 13 on a graphite base 11 produced as described above, the graphite substrate then providing the base contact to which a lead wire 25 may be connected by silver paste or a screw-in contact. In a further arrangement, a P-type layer is provided on top of the silicon layer by diffusion from gaseous boron trichloride and connection is made to this layer by soldering a lead to a nickel-plated spot; the arrangement provides a photo-voltaic cell.

Each support means 22, 23 has rails (37), Fig. 6 (not shown), 38 along which rollers 40 on the carriers can move, so that as winding of a roll, e.g. R1, Fig. 1 against a winding roller 5 proceeds, the carriers are pushed back along the rails. The two support means 22, 23 are adjustably mounted on a platform 14 by pinions 50, 51, Fig. 3, which engage racks 20, 21 on the platform. By manual operation of handles 52, 67, the positions of the support means can be adjusted axially of the web roll core for capture and later ejection thereof. When winding is completed, pneumatic cylinders 13, Figs. 1 and 2, are operated to pivot the platform and associated support means, carriers and shoots about point 9 to an unloading position. The roll R1 is urged against the winding roller 5, during winding, by two pneumatic cylinders, e.g. 75, Fig. 3 via linkages 70, 78, 72, one cylinder acting on each chuck so that the nip pressure across the roll can be varied. The cylinders are leaked as winding proceeds, to adjust the nip pressure, and when winding is completed, the cylinders pull the roll R1 away from the winding roller, the carriers actuate a microswitch 42, and unloading commences. Additional, pneumatically operated, nip rollers (105), Fig. 7 (not shown), may be provided. The chucks are of the expansible type. The apparatus may be duplicated to wind two or more rolls R1, R2, R3 against the same winding roller, e.g. for winding slit webs.

Inventor: DOUGLAS ERIC CHARLES
IPC: F42B3/18
Filed: 1957-12-19
Abstract: 906,181. Ammunition fuzes. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 2, 1958 [Dec. 19, 1957], No. 39580/57. Class 9 (1). An electric igniter or detonator, which may be used in proximity fuzes, comprises an electrically-conductive cylinder containing an igniting or detonating charge surrounding a conductor-rod 2, which projects from one end of the igniter and contacts a spring-finger 4 integral with a clip 3 surrounding the cylinder 1. The clip 3 and finger 4 form a short-circuit between the cylinder 1 and rod 2. The igniter is placed in a recess 6 formed in a housing 5, which is made in two parts of insulating material secured together by a rivet 18. A flash passage 7 leads from the recess 6. When the igniter and its housing is assembled with a contact maker comprising an insulating element 8 with a recess 9 in one face, the conductor 2 enters a socket 13 in an axial bore of a cylindrical boss 10 projecting into the recess 9. Socket member 13 is connected to a terminal 14 and the boss 10 is surrounded by a conducting sleeve 11 from which extends a lug 12 forming a second terminal, the terminals 12, 14 being connected to the free ends of electric leads, which are normally shortcircuited until the fuze is armed. As the rod 2 enters the socket 13, the finger 4 is pushed out of contact with the rod by the boss 10, thus breaking the short-circuit, and ultimately presses against the sleeve 11 to establish electrical connection between the terminal 12 and the clip 3. Housing 5 and the contact-maker may be spaced apart in the projectile and only move together when acted on by acceleration forces.

Title: Electrochromic display device
IPC: G09G3/16
Filed: 1975-09-30
Abstract: 1473772 Controlling light INTERNATIONAL BUSINESS MACHINES CORP 30 Sept 1975 39872/75 Heading G2F [Also in Division G5] In a display device comprising a transfer electrode El, a dump electrode E2 and a plurality of display electrode E3 immersed in a liquid electrolyte, a potential difference is first applied between electrodes E1 and E2 such as to deposit coloured material on E1, and subsequently a potential difference is applied between E1 and at least one electrode E3 so as effectively to transfer the coloured material to the selected electrode(s) E3. In Fig. 2, dot electrodes E3 are arranged in rows and columns, each column having a respective electrode E1 and E2 and the electrolyte being separated from that in adjacent columns by partitions 14 or by being contained in channels in a substrate. If the coloured material is such as to deposit at a cathode, it is initially deposited on selected electrode E1 by earthing the conductor 15 (FET 18, input T2) and by turning on selected FETs 19 to render corresponding electrode E2 positive. FETs 19 are controlled by a like array of bi-stables 23 forming an input/output register 24, AND gate 22 and control input Cl applied simultaneously with input T2. Subsequently an input T1 renders conductor 15 positive and, in the previously selected columns only, the coloured material is effectively transferred to the electrodes E3 of a selected row by activating the corresponding row input R2 (row conductor to earth). By repeating the process the array is scanned row sequentially. Non-linear resistances Z, e.g. oppositely poled diodes connected in parallel, are preferably provided between each electrode E1 and E3 and its row conductor. Erasure of the display is by turning on FETs 21 (input C2) and successively energizing terminals R1, or by short-circuiting the electrodes E3 to the dump electrode E2. The former erasure method may be used when the display requires refreshing to overcome dissipation of the coloured material by diffusion effects. The current between an electrode E2 and a coloured electrode E3 causes a current sense amplifier 27 to set the respective bi-stable 23 for a subsequent re-writing step. Partial or complete erasure of the display due to electrical read-out thereof may be counteracted similarly by applying sequential positive and negative current pulses across electrodes E2 and E3, the nett current being zero. During the positive pulse, terminal 29 is energized and the current between a written electrode and the electrode E2 produces an output from the amplifier 27, so that the following negative pulse restores the electrode E3 to its original written state. The device may also be constructed as a seven segment display.
