Abstract: 1,131,087. Track and train apparatus. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. 3 March, 1967 [22 March, 1966], No. 10148/67. Heading B7N. In a signalling arrangement of the type described in Specification 989,038 in which two trackside tuned coils are arranged in line transverse to the track and co-operate simultaneously with train carried pick-up apparatus, gate means are provided to feed the two resultant signals in series to the decoding apparatus on the train. The signals are picked up by units CD and CG and the CD signal is passed via normally open gate PD to the tuned amplifiers A1-A3. In dependence on the signal frequency one of the amplifiers is energized and passes a signal via a memory device and a pair of cascade gates in unit S to one of the inputs SD of decoding matrix M. The cascade gates also supply an output to block all the other inputs SD to the matrix and an output to a memory MS which changes its state whereby gate PD is now blocked and gate PG is opened. The second signal from pick up CG is now applied to the amplifiers and an input is applied on one of the second set of inputs SG to the matrix M which supplies an output control signal. When the train has passed over the coils a pilot signal f is again generated which via delay T switches the memory MS back to its initial state.

Title: Improvements in and relating to electrolytic devices
IPC: H01G9/00
Filed: 1951-05-01
Abstract: 763,189. Capacitors. BRENNAN, J. B. May 1, 1951, No. 10204/51. Class 37. An electrolytic device comprises a, porous flexible cathode and anode, the anode contacting a spacer along its length, and having a greater area exposed to the electrolyte than the cathode. The Figure shows the electrode arrangement in a condenser, having three anodes 2, 3 and 4 associated with a single cathode 1. The cathode consists of a thin base material 1a, such as paper, on which particles of a film-forming material such as aluminium are deposited on one side. The anodes are similar in structure to the cathode but the spray deposit is applied to both sides of the base material. Spacer 5 of paper or fibre separates the anodes and cathode. The cathode has a less effective area in contact with the electrolyte than have the anodes, since these have thicker layers of the porous material than the cathode. The portions 6 of the cathode intermediate the anodes may be impregnated with a lacquer or resin so that they are non-reactive electrolytically and serve only as a connecting member between the active sections of the cathode. Reference is made to Specifications 433,481, 744,231, [Group XXIX], and 763,188.

Title: Improvements relating to reflectors
IPC: F21V7/04
Filed: 1934-04-04
Abstract: 417,310. Reflectors. CURTIS LIGHTING-EUROPE SOC. ANON., 151, Longue Rue de l'Escaut, Hemixem, and BREIL, C., 24, Avenue Helene, Antwerp, both in Belgium. April 4, 1934, No. 10259. Convention date, Sept. 15, 1933. [Class 75 (ii).] A reflector for giving an asymmetrical light distribution suitable for illuminating a street or other elongated surface comprises in transverse section a number of parts of different curvature, the sections of the respective parts in all such transverse planes being geometrically similar. Fig. 4 shows one of four symmetrical quadrants of the section of a reflector adapted to be arranged on the axis of the surface and to project two diametrically opposite beams. Rays emitted by the source over an angle of 45‹ are projected by a part ab of circular, parabolic, or like curvature into a more concentrated beam aa1-bb1 of 10‹ spread in the general direction of the axis DD1 of the surface. Rays emitted over an angle of 20‹ are projected by a part cd into a concentrated beam cc1-dd1 of 10‹ spread in a direction more oblique to the axis DD1 than the beam aa1-bb1. Rays emitted over angles of 15‹ and 10‹ are projected by parts bc, de into a more diffused beam of 70‹ spread to illuminate parts of the surface near to the reflector. Either or both of the parts bc, de may be smooth or corrugated. Fig. 6 shows a section of a reflector adapted to be arranged to one side of the axis of the surface and to project two beams inclined to the axis. The parts ab, ab1 together intercept rays emitted over a total angle of 90‹ and project beams aa1-bb1, aa<1>1-b<1>b<1>1 which together have a spread of 20‹ in the general direction DO. The parts aobo, aoblo project similar beams in the general direction D1O, which is at 160‹ to the direction DO. The parts cd, codo each receive rays emitted over an angle of 15‹ and reflect them into beams of 10‹ spread to illuminate parts of the surface on the remote side of the axis. The part bkbo is spherical with its centre of curvature coinciding with the light source so as to reflect incident rays both on to the parts ab1, cd, codo, aob<1>o, to augment the rays falling directly on these parts. One or more of the parts b1c, b<1>oco, ddo, bkbo may be corrugated. In both forms the sections can be inscribed within circles of radius Ob so that such reflectors may be mounted in casings of circular transverse section and of substantially the same dimensions as those used for reflectors of the same power giving symmetrical illumination.

Abstract: 1,236,676. Determination of carbon dioxide in liquid samples. TECHNICON INSTRUMENTS CORP. 26 Feb., 1969 [27 Feb., 1968], No. 10306/69. Heading B1X. In an apparatus for the quantative analysis of a gaseous constituent e.g. CO 2 , a first stream of sample and acid segments spaced apart by intermediate segments of CO 2 -free air is drawn via pump tubes 18, 22 and 24 by peristaltic type pump 20 through mixer 40 where sample and acid segments are uniformly mixed and CO 2  liberated is entrained in the liquid segments, into a donar stream 42 which flows over one face of a gas permeable, liquid impermeable membrane 50. A second stream of CO 2 -sensitive colour reagent segments spaced apart by CO 2 -free air segments is drawn via pump tubes 28 and 26 by peristaltic pump 20 into line 54 and so into stream 82 which flows over the second face of membrane 50. Carbon dioxide gas entrained in the first stream iquid segments then diffuses through the membrane 50 into the second colour reagent stream segments and in doing so alters both the pH and optical density of this liquid. The latter may be measured by means of colorimeter 62, stream 82 being drawn through the colorimeter by means of pump line 30 connected to peristaltic pump 20. Pinch bars 20a and 20b serve to introduce the segments of CO 2 - free air into the two liquid streams respectively being operated by periodical release of air from lines 24 and 26. The colour reagent may be a dilute solution of cresol red buffered to pH 9.2 with tris-methane and ammonium hydroxide.

Title: Improvements in steam turbines working with high degrees of superheat
IPC: F01K7/22
Filed: 1923-04-16
Abstract: 196,913. Akt.-Ges. Brown, Boveri, et Cie. April 26, 1922, [Convention date]. Drawings to Specification. Working-fluid supply.-In a steam turbine working with a high degree of superheat (steam temperature, above 375‹ C.) that part of the turbine which works with highly superheated steam (above 325‹ C.) has only rotors running normally at small peripheral speed (below 160 metres per second). This peripheral speed is based upon the strength of the rotor material at the temperature determined by the utilised heat drop. The first unit wih the small rotors may be an independent turbine driving its own dynamo, or it may be coupled through gearing to the main turbine, or it may be mounted on the same shaft as the main turbine. The Specification, as open to inspection under Sect. 91 (3 (a), gives 350‹ and 300‹ C. respectively as the two temperature limits referred to above. This subject-matter does not appear in the Specification as accepted.

Abstract: 454,596. Singeing carcasses. GJERSTRUP, T. F. L., 4, Kalvebod Brygge, Copenhagen. April 5, 1935, No. 10621. [Classes 51 (i) and 51 (ii)] In an oil-fired pig-singeing furnace comprising two horizontally movable sections 1, 2 which are relatively displaced by mechanism 5, 6, 7 to provide for introduction and removal of the carcass, a single fixed burner 8 is provided below the furnace. The burner delivers into an upwardly expanding flame-spreading ring constructed of or lined with refractory material and formed in two sections 9, 10 secured to the respective furnace sections 1, 2. The burner 8 and ring 9, 10 are eccentrically mounted with respect to the axis of the furnace and the carcass is so positioned that its back portion, which requires more heating, is adjacent that side of the furnace nearest the burner. The latter is supplied with oil and steam through pipes 11, 12 fitted with filters 13, 14, the oil pipe 11 being also provided with a valve 15, the operating arm of which is pivoted to a rod 17 having a notch 18 engaging a rod 19 secured to the furnace section 2. This arrangement effects a reduction in the oil supply when the furnace is opened and, by making the notch 18 much wider than the rod 19, it is ensured that this reduction, and similarly the restoration to full supply on closing the furnace, are not effected until the sections 1, 2 have moved some distance away from and towards each other.
