Title: Improvements relating to locomotive brake equipment
IPC: B60T15/04
Filed: 1941-11-14
Abstract: 563,615. Fluid - pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Nov. 14, 1941, No. 14664. Convention date, Feb. 28, 1941. [Class 103 (i)] A driver's brake valve for automatic compressed air systems has release and running positions in both of which the brake pipe supply is effected by a feed valve but the supply passage in the running position is relatively restricted to ensure brake application in the event of breakage of the train-pipe. Further, the action of the feed - valve is rendered dependent upon the rate of flow so as to prevent overcharging of the train-pipes. The driver's valve comprises a chamber 18 to which is connected by the pipe 8 the control chamber 56 of the feed valve 3. The brake pipe equalizing discharge valve 11 and reservoir 10 are connected by passage 14 to the seat of the rotary valve member 21 and in the release and running positions by the cavity 25 and port 24 in the rotary valve to the chamber 18. The rotary valve has two right-angle passages 38, 39 which in the release position both register with an arc-shaped passage 32 in the valve seat and with a wide passage 36 in the casing but in the running position shown in Fig. 6 only the passage 39 which has a relatively small port 41 so registers. The passages 32, 36 are connected respectively to the brake pipe 1 and the supply pipe 7 from the feed valve 3. A small port 42 connects the passage 39 and the chamber 18. The feed valve comprises a piston 45 operating a slide-valve 48 in a chamber 47 which is connected to the main reservoir 44 and by a restricted passage 60 and an air-strainer 59 to the chamber 46 above the piston. A diaphragm 54 which is subject above to the pressure of the spring 55 which determines the normal brake pipe pressure and below to the pressure in chambers 56 and 18 is arranged to operate a valve 57 which controls communication between chambers 56, 46. With the driver's valve in the release position, Fig. 1, for charging, the chambers 56, 18 are connected to the brake pipe 1 through port 42 so that the valve 57 is opened by spring 55 reducing the pressure in chamber 46 so that the piston 45 and valve 48 are moved upwards by the main reservoir pressure acting against a spring 61 as shown in. which the valve ports 51 fully register with passages 52 and air from the reservoir flows freely by pipe 7 and passages 38, 39 to the brake pipe 1. The relation of the passage 42 to the passage 39 is such that a suction effect is created bv the flow from the pipe 7 to the brake pipe 1 which tends to delay the rise of pressure in the chambers 18, 56 to an extent dependent upon the rate of flow to the pipe 1: As the pressure in this pipe and in the chambers 18, 56 rises the valve 57 gradually closes causing the piston 45 to be gradually lowered by the spring 61 and gradual shutting off of the supply passages 52. The driver's valve is then moved to the running position in which supply to the brake pipe is restricted to the capacity of the port 41.

Title: Improvements relating to electric rotary converters
IPC: H02K47/08
Filed: 1926-06-21
Abstract: 276,603. Townend, R., Juhlin, G. A., and Metropolitan-Vickers Electrical Co., Ltd. June 21, 1926. Rotary converters; commutating poles and windings.-In a rotary converter subjected to inverted operation, the commutating poles are provided with auxiliary windings so arranged that their excitation per ampere of main current in the machine changes when the action of the machine changes from normal to inverted conversion. Fig. 1 shows a converter in which this is effected by an auxiliary commutating winding 24 which, in normal operation, opposes and with inverted working assists the main commutating winding 15. The converter is shunt-excited at 20 and series-excited by a coil 21 in series with the oommutating coils 24 and energized by an exciter 23. the field coils 26 of which are connected by a change-over switch 27 across a series resistance 16 in the main lead 17 of the converter. When the converter changes to inverted working, the switch 27 is thrown over, by a reverse-power relay or other means, so that the commutating coils 24, 25, which normally oppose, aid each other magnetically, notwithstanding the reversed current in the main leads, and a greater commutating field is produced than that which obtains in normal working. As an alternative to reversing the current in the coil 26 bv a switch 27. this coil may be wound in two opposing parts and switchgear provided so that one part is used for normal and the other for inverted conversion, or so that one which overpowers the other is shortcircuited for normal running and operative for inverted working. In the arrangement shown in Fig. 4, applied to two converters 11, 11<a> in series, with their shunt coils omitted, the normal commutating-pole windings 15 are connected across the continuous-current terminals 17, 19 in series with the series coils 26<c>, 26<d> of the exciter 23 which supplies the series coils 21, 21<a> of the converters. Each converter also has an additional oommutating-pole winding 24, 24a connected across the exciter in parallel with its shunt coil 32 and having a short-circuiting switch 34. The coil 26d, which opposes and is stronger than the coil 26<c>, is short-circuited by a contact 30 during normal operation of the converters and the contact 34 is open. When the converters work inverted, the, contact 30 is opened, for example by a reverse power relay, so that the winding 26<d> prevails and maintains the same exciter polarity, and simultaneously the contact 34 is closed, thereby adding the commutating effect of the coils 24, 24a to that of the coils 15, 15<a>. A resistance 31 or a lead of sufficiently high resistance is connected in series with the coil 26d and diverters mav be used across the coils 26<c>, 26<d> as shown in dotted lines. The auxiliary commutating coils 24, 24a may alternatively be connected in series with the coil 26<d> and the resistance 31 so that they are short-circuited by the contactor 30 during normal operation of the machines and are energized when the operation becomes inverted.

In a device comprising a luminescent diode mounted on and optically coupled to a photodiode by a layer of a chalcogenide glass which plastically adheres to the surface of the photodiode at the designed operating temperatures. the photodiode comprises a body of one conductivity type with a region of the opposite type extending over part of one surface, a protective layer covering the boundary of the region and the remainder of the face of the body the region being surrounded by a high conductivity guard ring of the same conductivity type as the body, the guard ring being contacted by an associated metal layer on the surface of the protective layer. The guard ring, which is situated at the edge of the depletion layer, prevents the formation of an inversion layer in the surface of the body below the protective layer which otherwise results from the ionization of the chalcogenide glass. As shown, Fig. 3, the planar photodiode 2 comprises a body of N-type silicon having a diffused P-type region in its upper face surrounded by an N+ type guard ring produced by diffusion of phosphorus. The surface of the P-type body and the junctions are protected by an oxide layer 4 and the guard ring is contacted by an aluminium layer 5. A GaAs light emitting diode 1 is mounted parallel to the photodiode 2 by means of a layer 3 of a low melting point chalcogenide glass through which the light passes. The light emitting diode may be produced by alloying tin-zinc alloy to an N-type GaAs wafer. The assembly is mounted on a gilded header 6 filled with insulating glass 7. The chalcogenide glass may comprise 15% As, 85% Se or 28% As, 40% S, 32% I. In use the luminescent diode 1 is forward biased and the photodiode 2 is reverse biased. The body of the photodiode may be of P-type silicon in which case the guard ring is a P+ type region produced by diffusing-in boron.

IPC: B05B7/06
Filed: 1960-10-20
Abstract: A method of electrostatic spray painting an article by means of a paint atomizing and charging device comprises atomizing the paint into a spray and depositing the spray upon the article with the aid of an electrostatic field, the method including the steps of maintaining the article at substantially earth potential, establishing a high voltage electrostatic deposition field between the article and a charging electrode on said device at high potential, the charging electrode being effectively shaped, at that part nearest the article, as a point, thereby to produce in the immediate vicinity of the electrode a zone of high ionization, directing into said zone the discharge from the adjacent discharge orifice of an orifice type mechanical atomizer, whereby finely atomized paint particles produced in or directed into said zone are charged and thereupon move under the influence of the field between said charging electrode and the article, procuring that substantially all the paint in the discharge traverses said zone whilst maintaining the region between said zone and the article free of any element which would significantly diminish the intensity of ionization or the deposition effect of said field in said zone, and charging said spray to a charge of at least 3/4 microcoulomb per gram. The spray pattern may be altered by means of jets of air issuing from apertures adjacent to the orifice of the atomizer.  Apparatus for carrying out the method of the invention is identical with that described in Specification 1,017,859.  Coating foil.  To determine the ratio of charge to mass of the particles, a paint comprising an alkyd resin and titanium dioxide is sprayed by the method of the invention on to aluminium foil, and the current carried by the spray is compared with the increase in weight of the foil.
