Abstract: 1490158 Sintered discharge lamp electrode PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 21 May 1975 [12 June 1974] 21805/75 Heading C7D [Also in Divisions B3 and H1] A discharge lamp electrode comprises a head mounted on or integral with a pin, the head having been fused to form it into at least half a sphere having composition after fusing of 100 parts by weight made up of 20-80 of W, 80-20 of one of TaC, HfC, ZrC, together with 0-5 further parts of Th or U added as element, oxide, boride or carbide. The head may be made by conventional granulations of the mixed powders with e.g. acrylic binder, pressing and sintering in H 2  to form a ring or recessed disc to fit on a W pin or in the form of a short pin of the head composition. The head is then fused to form the spherical shape by making it the Jower electrode opposite W in an arc in inert atmosphere. Alternatively the head may be formed by coating a tapered W pin with a paste of any one of Ta, Hf, Zr carbides or the equivalent (1:1 atomic) elements, together with sufficient Th or U added as before and with 0-5% W based on the above carbide to ensure that, after fusing, the head absorbs W to bring it into the same range of composition as sintered heads. Convential W coils carrying emitter material will normally be fitted round the pin, omitted if Th or U is included in the head. The.W of the pin may also include thoria. The electrodes, suitable for high pressure Hg lamps with or without halogens, or for high pressure Na lamps and compact arc lamps on A.C. or D.C., stabilize the arc roots.

Title: Improvements in or relating to pressure responsive indicating instruments
IPC: G01L7/00
Filed: 1947-08-08
Abstract: 642,677. Indicating-apparatus; pressure gauges. ELECTROFLO METERS CO., Ltd. Aug. 8, 1947, No. 21823. Convention date, Dec. 16, 1939. [Classes 106 (ii) and 106 (iv)] An indicating instrument comprises a condition responsive element, a lever or yoke 86 pivotally mounted at 90 on a fixed axis and connected to the element to be rocked thereby, a flat balance spring 98 engaging a slot in an extension 92 in one end of the lever 86, a bellcrank arm 102 having one portion parallel to and adjustably connected with the spring 98 so that the effective length of. the latter can be varied, and means operated by a screw 46 to tilt the bell-crank 102 about its pivot to vary the initial loading of the spring, and thus zeroize the indicator pointer. The bell-crank 102 has one portion slotted at 104, and secured to the spring 98 by blocks 106 (not shown) and a clamp screw 107; the other portion is slotted to guide a nut 110 which is engaged by the screw 46. An extension 116 of one pivot axle 88 secured to the yoke 86 is adapted to move a pivoted point 18 through a lever 118 (not shown) and a link 120 connected to the pointer near to the pivot 16 of the latter. Counterbalance weights 122 are threaded on an extension of the pointer. The invention is described as applied to a differential pressure gauge for measuring draught, and the instrument comprises a die cast casing 10 with a top cover 26, a transparent side cover 14, and a translucent dial 22 over which an indicator 20 on the pointer 18 moves. A flange 28 and several tapped holes in the base 12 facilitate mounting the instrument. The base 12 is formed with an inwardly-projecting flange 30 supporting a flexible diaphragm 32. A cover 34 clamped by screws 36 encloses the diaphragm. Passages lead from tapped holes in the casing to both sides of the diaphragm. A stem 76 on the diaphragm is pivoted to end of a lever 82 which passes through a fluid-tight seal 84 in the cover and is secured to the yoke 86. The pivots 88 secured to the yoke are aligned in the plane of the seal 84. The sensivity of the instrument can be altered by slackening the screw 107 and sliding the blocks 106 and spring 98 towards or away from the pivot 90. To measure greater pressures, the effective area of the flexible diaphragm 32 can be limited by introducing ring supports within the pressure chamber, one on each side of the diaphragm.

Abstract: 1,008,936. Telegraphy. MARCONI CO. Ltd. March 9, 1964 [May 31, 1963], No. 21880/63. Drawings to Specification. Heading H4P. In a data transmission system an n-bit parity character follows each n-bit information character. The x-th bit of the parity character is the parity of the n-bit character less the x-th bit. Assuming that the parity number is always odd or always even it is shown that the parity character is either the same as, or the inverse of, the information character, dependent upon whether the number of bits of given polarity in the information character is even or odd. The transmitter thus comprises means for transmitting any character twice, the second transmission being inverted if necessary. The system will correct single errors at the receiver and will detect multiple errors. A receiving arrangement is described in the Specification.

Title: Method of concentrating audible signals by interference in any medium
IPC: G10K11/28
Filed: 1925-09-01
Abstract: 239,513. Blondel, A. Sept. 3, 1924, [Convention date]. Locating sounds; navigable channels and courses, systems of indicating.-Comprises a method of concentrating sound signals towards the horizon consisting in emitting sound waves of the same phase by four horns placed vertically above one another at intervals equal to half a wave length of the sound emitted; feed pipes being arranged such that each of the four paths has produced in it a resonance so that the opening in each horn may be a centre of sound oscillation while the openings of the sirens are centres of pressure. Four horns 6 from a single siren s are arranged one above the other at distances of half a wave length, the lengths of horns being adjusted so that the sound is in phase at the mouths of the horns. The four horns may be supplied by four independent pipes 5 from the same siren or the pipes may be grouped in pairs. In a modification the supply is made separately through two or four sirens of the drum type synchronized by being mechanically coupled by their shafts or electrically coupled by electric motors driving the shafts. In a further modification, the supply of the pipes is carried out separately by separate piston sirens the vibrations of which are synchronized bv establishing between the pipes at points in the same phase of vibration synchronizing pipes each having a length corresponding to a wave length. The Specification, as open to inspection under 'Sect. 91 (3) (a) comprises also the following subject-matter :-A set of sixteen vibrators or horns in a vertical plane to produce concentration of sound in a horizontal beam is shown in Fig. 10 (Cancelled). Two small horns, Fig. 6 (Cancelled), placed one behind the other in a horizontal plane may be used, the mouths being disposed a half wave length apart. The one horn, as shown, may open out from the other, the rear one being of twice the cross-sectional area; or separate horns may be used. This form utilizes the principle described in connection with directional wireless transmission in Specification 11427/03, [Class 40, Electric telegraphs &c.]. Two such groups may be superposed, the distance between the two axes being a wave length. A set of groups may be arranged as in Figs. 11, 12 or 13 (Cancelled). A large number of conical horns may be used and " the difference in phase between successive orifices - - - must be proportional to the geometric distances between the orifices. The axis of the horns may be vertical and reflectors used to direct the sound horizontally. Two sound beams produced according to the invention may be used for the demarcation of a channel or direction by being placed so that the angle between them is bisected by the direction. The sounds are emitted alternately and are of the same power but of different pitch. Periodically the two devices may also emit the same sound out of phase to produce silence along the channel to be marked. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and connected with dynamo electric machines
IPC: H02P29/00
Filed: 1928-07-28
Abstract: 318,357. English Electric Co., Ltd., Calverley, J. E., and Donnelly, W. July 28, 1928. Exciting.-In order to maintain constant the power output of an electric generator driven by a prime mover such as an internal combustion engine particularly in traction equipment where the generator supplies the vehicle motors, the generator is separately excited from a source of substantially constant potential in series with a substantially constant speed booster, the booster having a field excited to saturation by the separate source and having an opposing field varying as the generator load and causing the resultant booster field to pass through zero and reverse as the generator load increases. The generator 1 having compensating and interpole windings is provided with a field winding 2 excited from a constant potential source such as a battery 3 in series with a rheostat 8 and a booster 4 driven at constant speed by a machine 5 which may be supplied from the battery 3. The booster is excited to saturation by a winding 6 supplied from the battery and produces a voltage acting in the same direction as the battery. The booster has also an opposing winding 7 carrying the whole or a portion of the load current. On low loads the battery and the booster assist, but as the load current increases, the booster voltage drops to zero and then reverses, the booster then operating as a motor. If the prime-mover operates always at constant sped, the booster may be directly coupled thereto and the motor is dispensed with. If a definite short circuit current is required from the main generator, for example for starting purposes, the booster set may be caused to run faster by inserting a resistance in the field circuit of the machine 5 so that the excitation of the main machine is reduced since, on account of the short-circuit current in the winding 7, the booster voltage will be acting in opposition to the battery voltage. The battery 3 may be used for lighting purposes and for starting the prime mover and may be maintained charged by a separate generator driven by the prime mover.
