Abstract: 1,166,575. Couplings. FORD MOTOR CO. Ltd. 14 March, 1968 [22 March, 1967], No. 12376/68. Heading H2E. [Also in Division C7] In a circuit for electrodeposition of paint or other organic material on to the surface of conductive substrates, connection between the electrode 11, which constitutes the substrate, Fig. 1, and the supply lead terminal 13 is made via a detachable connector-conductor unit 17. A clamping means 19 holds the electrode 11, terminal 13, and connector-conductor unit 17 together. This unit 17 comprises a conductorpad 33, Fig. 2, and a bolt 37-2, with a resilient member 35 encompassing the vertical walls of the pad. The member 35 has a channel 35-1 in its lower surface, inside a flexible peripheral lip 35-2, the whole structure forming a "suctioncap", which effectively prevents the access of electrolyte to the conducting pad, which would otherwise become coated with organic material. The member 35 is of silicone rubber or other material which can withstand the heat of the subsequent baking necessary to polymerize the organic coating. Ready detachment of the electrode is facilitated by the nut and bolt arrangement of the clamping means 19, or, in another embodiment (Fig. 3, not shown) by release of a spring grip. The clamping means may be insulating or conducting if it does not form part of the circuit (as in Fig. 1) but otherwise must be conducting (e.g. as in Fig. 3).

Title: Improvements in electrical inductive apparatus of the eddy current type
IPC: H02K49/04
Filed: 1941-09-27
Abstract: 582,409. Eddy-current brakes. WINTHER, M. P. Sept. 27, 1941, No. 12549. Convention date, March 19. [Class 103 (i)] [Also in Groups XIX and XXXV] In eddy-current apparatus such as an electromagnetic brake, one relatively movable member is a spider to the periphery of which are secured flux-concentrating bars, spaced apart and extending axially, and the other member comprises C-shaped members embracing the ends of the bars and energized by peripherally wound coils producing a toric flux passing through the bars. The periphery of the spider 15 carries grooves 19 in which the bars 21 are fitted and stabilized by welded end spacers 23. The stationary member comprises two C-shaped portions 25, 27 which closely embrace the ends of the bars and are energized by coils 49, 51 so as to produce a "toric" flux which passes nearly perpendicularly across the gaps thus formed. As the spider rotates the bars cause the flux to traverse the stationary surfaces 41, 43 and 53 and induce in them eddy currents to give the required braking torque. The dissipated energy is carried away by water which flows in series through channels 58, 37 and 58, 39. In a modification the flux concentration is increased by tapering the bars where they aproach the inductor surfaces, preferably reducing their cross-section at the point by 30 per cent.

The cells may be arranged in a tube wound into a solenoid about a magnetic core, or alternatively may be arranged in the form of shells surrounding a magnetic core.
Patent GB-115016-A (GB)
Title: Improvements relating to Electro-pneumatic Braking Systems.
Inventor: TURNER WALTER VICTOR
IPC: B60T13/68
Filed: 1917-09-05
Abstract: 115,016. Turner, W. V. April 17, 1917, [Convention date]. Fluid pressure. - Relates to electro-pneumatically controlled brake mechanism such as described in Specification 2455/12, and consists in connecting the pistonchamber of the quickaction valve to the trainpipe in electrically-controlled emergency applications so that this valve is kept open as long as the electrical emergency valve is energized and pressure exists in the train-pipe. Undesired release of the brakes in case the driver's valve is in position to feed the train-pipe during an electrically - controlled emergency application as by a " deadman " device is thus prevented. The valve mechanism shown includes a triple valve 2 adapted to effect the usual connexions of the train-pipe at 8 to the auxiliary reservoir at 12 and of this reservoir to the brake cylinder at 19; an emergency valve 3 for effecting the opening of the quick-action valve 30 in pneumatically controlled emergency applications, and electrically-controlled release servies and emergency valves 32, 34, 36. The piston chamber 20 of the emergency valve 3 is connected to the train-pipe by passage 7 and the valve chamber 22 and chamber 24 of this valve are charged through the groove 42. The chamber 43 is also charged from the train-pipe through the chamber 22 and passages 44, 45. The valve mechanism 3 affects the opening of the quickaction valve 30 in pneumatic emergency applications by connecting the chamber 43 through passages 45, 29 to the piston-chamber 28 of the valve 30. This valve re-closes when the pressure in chamber 43 has leaked down through the port 50 in the piston. The electric emergency valve 36 is adapted to connect the passage 46 leading from the train-pipe passage 7 to the passage 47 leading to the piston-chamber 28 of the valve 30, which is thus opened by train-pipe pressure when the valve 36 is energized and remains open as long as the valve is energized and there is pressure in the train-pipe. The valve 30 closes when the valve 36 is de-energized by equalization of pressure through the port 50 in the piston. The passage 47 communicates with the chamber 48 of a piston 38 controlling a switch in the emergency magnet circuit, interruption of which is thus presented when an application has been initiated.

Title: Improvements in printing telegraph transmitters
Inventor: TEDHAM LESLIE THOMAS
IPC: H04L17/02
Filed: 1959-04-15
Abstract: 874,880. Printing-telegraph transmitters. CREED & CO. Ltd. April 8, 1960 [April 15 1959], No. 12745/59. Class 40(3) Printing telegraph transmitting apparatus comprising a tongue operated to mark and space contacts by a movable member controlled by an interposer positioned according to the nature of the elements of a signal code combination includes means to operate the movable member to move the tongue from the space contact to the mark contact earlier than when the tongue is moved from the mark contact to the space contact so that the durations of the transmtted space and mark elements are equal and the usual spacing bias in current-no current transmission is eliminated. Link members 1 selectively moved in a vertical direction following operation of a key of a keyboard have upper portions 10 which correspondingly obstruct or do not obstruct the arms 2 of pivoted rockers 5 having arms 4 which sequentially engage flats 9 on a cam barrel 8 mounted on a shaft 7 released by the depression of a key. The leftward movement of the arm 5 of any rocker 3 engages a bar 11 spanning all the rockers and carried by a frame 12 having an extension 13 provided with a pin 14 on which is mounted the interposer 15 formed with an upward extension 16 and a downward extension 17. The transmitting tongue 36 is operated by two arrow-shaped members, as shown at 21, mounted in a carrier 19 pivoted at 20 and having limited angular movement defined by a fixed projection 23 and a slot 25 in an arm of the carrier 19. The projection 17 in its two extreme positions is above projections on independent strikers 26, 27 controlling respectively "spaceto-mark" and "mark-to-space" transitions. The strikers 26, 27 are connected to separate associated arms 29, 30 mounted on a shaft 28 and biased by a spring 33 into engagement with two identical seven-lobed cams 31 also mounted on the shaft 7. The arm 29 is shorter than the arm 30, and with the rocker 15 in its right-hand (full line) position, the striker 26 is free to move upwardly, and take with it its contact-operating member 21, earlier than when the interposer 15 is in its left-hand (dotted line) position in which the striker 27, with its contact-operating member, moves upwardly by the engagement of the longer arm 30 with a recessed portion 32 of its associated lobed cams 31. Both strikers 26, 27 will attempt to move upwardly when the ends of the arms 29, 30 register with the depressed part 32 of the two cams 31, but one of the strikers will be blocked since it has its end projection immediately below the projection 17 of the interposer 15 which is rotated slightly on its pin 14 until its vertical movement is arrested by engagement of its upward extension 16 with a leaf spring 34.

Patent GB-727857-A (GB)
Title: Improved preparation of titanium monoxide
IPC: C01G23/04
Filed: 1953-05-07
Abstract: Titanium monoxide is produced by heating (a) a mixture of titanium dioxide and carbon, or (b) a mixture of titanium dioxide and titanium carbide, or (c) titanium carbide, to a temperature of at least 1,000 DEG  C., preferably 1,800-2,100 DEG  C. in an atmosphere of (a) water vapour, or (b) carbon monoxide, or (c) a mixture of said gases.  The term "titanium dioxide" includes titanium dioxide-containing materials such as ilmenite.  The initial ingredients may be ground to minus 325 mesh (Tyler standard) and briquetted.  The product should be cooled in a non-oxidizing atmosphere.  An induction furnace may be used, but an arc furnace is preferred.  This may be of the pot type, having a water-cooled shell and a cover through which the electrode passes leaving a narrow annular opening.  The electrode may have a central bore through which gas is passed into the reaction mixture. The reactants are protected from oxidation by the carbon monoxide and/or hydrogen which are formed and burn as they emerge from the annular opening.  The water vapour and carbon dioxide (which must be free from nitrogen and oxygen) are added at a rate slightly in excess of that stoichiometrically necessary (equations are given), and in the case of water a large excess may be added if a corresponding quantity of carbon is used.  If carbon monoxide alone is used, or in other cases where removal of residual carbon is difficult, said removal may be effected with water vapour. Examples using various starting materials are given.
