Title: Improvements in photo-sensitive surfaces
IPC: G03C1/64
Filed: 1926-05-17
Abstract: 280,252. Martinez, M. May 17, 1926. Colour photography; plates, films, and papers; sensitive coatings, preparing.-Sensitive layers which print out respectively in red, blue, and yellow, comprise (1) for red, a derivative of urea such as alloxan, alloxanic acid, alloxantine or .murexide, either alone or combined with each other or with metallic salts such as alkaline &c. oxalates, silver, ferric or mercury salts; (2) for blue, a mixture having as its basis ferric salts in conjunction with a cyanide such as mercuric or potassium cyanide, and potassium ferricyanide; and (3) for yellow, silver lactate in conjunction with metallic oxalates and ferric salts, and preferably also with an excess of lactic acid. Detailed formulae are given in the Specification for preparing solutions of the sensitizers, which may be coated on cellulose &c. supports, for example on cellophane. The layers require no treatment after printing, other than washing in water, except in the case of the red sensitive layer, which may require a fixing agent such as chloride of mercury or of tin, or silver nitrate. The agent may be applied either in the sensitizing bath, or in the form of a coating separately applied to the support, or in a bath for treating the layer after exposure. Emulsions may be prepared by employing as the vehicle gelatin, albumen, gum, or soluble starches such as arrowroot. Three-colour compound sensitive material may be produced, each layer or sector of which is sensitized with one of the above-mentioned sensitizers. S'pecification 280,053 is referred to.
Patent GB-875461-A (GB)
Title: Lubrication systems of gas turbine engines
Inventor: MCDOWALL CHARLES JAMES
IPC: F01D25/20
Filed: 1960-04-08
Abstract: 875,461. Gas turbine plant. GENERAL MOTORS CORPORATION. April 8, 1960, No. 12542/60. Addition to 862,989. Class 110 (3). [Also in Group XXXIV] In a gas turbine 10 comprising an axial flow compressor 12 and circumferentially spaced combustion cans 36 joined to a fuel nozzle 40, supplying an axial flow turbine 16 at 44, the high- and low-pressure bearings 58, 60, 62 and 56 are each supplied with the same amount of lubricant regardless of the change in environmental pressures, by maintaining the pressure differential between the lubricant supply and discharge, the same for each bearing. The compressor from bearing 56 is surrounded by air at substantially atmospheric pressure, and the compressor rear bearing 58, mid frame bearing 60, and turbine front bearing 62 environment pressures are substantially higher. A pump 80 draws oil from a tank 70 and delivers it to the bearing 56 via valves 88, 136 and conduit 64 and to bearings 58, 60, 62, through conduits 71, 72. Oil from the bearings is collected at 66 and 74, and delivered back to the tank by pumps 69, 79. The valve 88 has a part-spherical head 120 at one end of a rod 110, and a piston 118 at the other end. One side of the piston is connected to the oil discharge from the bearing 56 by a conduit 134, and the other side is connected to the discharge from the bearings 58, 60, 62 by a conduit 78. In operation, the relief valve seat 162 is adjusted so that the valve head 152 lifts at say 65 p.s.i., thus maintaining this pressure differential between the oil supply in conduit 64, and discharge in conduit 134, which is at atmospheric pressure. Initially the pressure in chambers 184, 186 and 90 of the valve 88 is atmospheric. The pump 80 delivers oil through conduit 86, lifts the valve head 120 and delivers oil to the bearing 56. The pressure in conduit 64 rises until a pressure of 65 p.s.i. is reached, whereupon the valve head 152 lifts and the surplus oil passes back to the pump inlet and the tank via conduit 138. The pressure in chamber 90 is now 65 p.s.i., and head 120 is seated, thus increasing the oil pressure in conduit 71. When the turbine is started the environmental pressure around the bearings 58, 60, 62 increases, and therefore the discharge in the conduit 78 increases, and consequently the pressure on the top of the piston 118 increases. Since the effective area of piston 118 is the same as the valve seat 122, the pressure in line 71 feeding the bearings 58, 60, 62 will always be equal to the pressure in chamber 186 less that in chamber 184 plus the differential pressure required, in this case 65 p.s.i. Therefore the pressure in line 71 is always equal to the difference in the ambient pressures in the high- and low-pressure bearings plus the differential pressure in the low-pressure bearing determined by the valve 136.

Title: Infra red, heat and ultra short wireless wave signalling apparatus
IPC: G01S3/783
Filed: 1931-05-04
Abstract: 384,325. Signalling by infra-red, heat, and short wireless wave radiation. HAWKER, T. M., Casa Sylva, La Baule les Pins, Loire-InfÚrieure, France. May 4. 1931, No. 13082. [Class 40 (v).] For signalling between ships, or aeroplanes, or between either of these and land stations in which use is made of infra-red, heat, or ultra-short wireless waves, the receiver is adapted to traverse the horizon, and comprises two detecting elements controlling the direction of traverse, so that when a signal is detected, the receiver is automatically traversed and maintained facing the transmitter until signals cease, when the receiver continues to traverse the horizon. The two detecting elements 4, 5 and reflector 3 are mounted on a base 1 rotating about an axis 2 under the control of a reversible motor 20. Radiation reflected from the mirror 3 falls on one or other of the detectors 4, 5 located on each side of the focus, and the currents generated are amplified at 6 and control relays 8 which energize one of the solenoids 9, 10, to actuate the switch 12, 13 and control the direction of the current in the motor circuit. When the detectors 4, 5 are equally influenced the switch 12 is held out of contact with the motor circuit, and the motor stops. Contacts are arranged so that at the limit of the traverse the appropriate solenoid 9, 10 is energized to reverse the motor. Each detector may have a separate reflector, and for ships, several such receivers may be used each traversing a segment of the horizon and each mounted on gimbals or minnions to counteract the motion of the ship. A loud-speaker 7 may be used to give an audible reproduction of the signals received.

Title: Improvements relating to devices for feeding a continuous web or band of material
IPC: D06C3/00
Filed: 1948-05-13
Abstract: 644,523. Feeding webs. FERRANTI, Ltd., and FRANCE, J. H. May 13, 1948, No. 13100. [Class 100 (i)] A web-feeding device comprises a feed member for conveying the web over an arcuate path, and a drive member having pins outwardly projecting from its periphery, at least a part of which follows a second smaller-radius arcuate path located on the concave side of the first arcuate path, the part of the envelope of the points of the pins lying on the convex side of a part of the first arcuate path (so that the pins pierce the web) in a region where the two paths are in proximity, the drive member being moved at a speed such that it drives the web at approximately the same speed as that of the feed member periphery. In one form the periphery of a felt-, rubber-, or as shown bristlesurfaced feed-wheel 1 provides a quadrantal path 4-5, whereby the downwardly moving cloth &c. 3 is delivered on to a horizontal stenter 7 whose pins 6 extend through the cloth into the bristles; a smaller wheel 10 is arranged so that its rim 14 approaches the path 4-5 while a single row of radial or backwardlycanted pins 13 extends therebeyond to pierce the cloth 3, the wheel 10 being so geared to the wheel 1 that the point on the periphery of the latter at which any pin 13 is withdrawn at 16 is the same as that at which the same pin had previously emerged at 15; the peripheral speed of the wheel 1 may be the same as that of the stenter 7 or faster to provide an over-feed, the pin withdrawal point 16 being close to the points of the pins 6 to reduce the length of uncontrolled cloth 3 to a minimum. The axis of the wheel 10 may be adjustable relative to that of the wheel 1, angularly to vary the distance between the point 16 and the pins 6, and radially to maintain the maximum pin protrusion at 20 constant despite wear of the bristles on the wheel 1. The pins 13 may be arranged to project through a circumferential slot in the wheel 1, or the wheel 10 may be close to one side of the wheel 1 or between two wheels 1; wheels 1 and 10 may be arranged on both sides of the cloth 3, the pins 13 acting on the selvedge. A card clothing &c. surfaced roller may be provided to ensure that the pins 13 pierce the cloth 3 instead of forcing it off its path 4-5, and where the points 4 and 15 are adjacent or coincident, a guide roller receiving the cloth from a direction other than vertical may be used for this purpose. In another form the feed and drive members may comprise endless belts or chains driven at points remote from the web.

Abstract: 132,435. Bellescize, H. J. J. M. de R. April 29, 1918, [Convention date]. Addition to 132,434. Wireless telegraphy.-Comprises a modification of the invention described in the parent Specification in which complete symmetry is obtained in the receiving- circuits in order to minimize disturbances due to earth currents &c. which reduce syntony and render inaccurate the determination of direction by radio-goniometric methods. In one form of the invention shown in the parent Specification, the oscillation circuit LC is coupled to the detector circuit L<1>C<1> by two coils a, b arranged symmetrically with respect to the con-' denser C and wound so that the induction effects between aL<1> and bL<1> will assist each other when produced by currents flowing round the loop LC. According to the present invention, disturbances due to electrostatic coupling between the coils aL<1> and bL<1> are avoided by connecting a point on the circuit CL to earth or to the Faraday's cage that protects the receiving system. As shown in Fig. 3, the circuit CL is connected to earth or the cage through condensers C'.

Title: Improvements in or relating to electric motors of the submersible type
IPC: H02K5/132
Filed: 1945-05-28
Abstract: 623,369. Cooling dynamo-electric machines. HAYWARD, TYLER & CO., Ltd., HOWARD, G: P. E., and IVANOFF, V. May 28, 1945, No. 13304. [Class 35] A submersible pump motor has means independent of the external pump, for circulating cooling water through a central hole in the shaft, out of radial holes in the shaft, through parts of the machine to be cooled and back to the central hole. As shown, the water enters the shaft at its lower end at which is fixed a Mitchell thrust bearing 43, 44, whose position is adjusted by means of a screw 47 and a tommy bar 48. The rotation of the shaft causes water to leave by the lateral holes 63 in a wide part of the shaft below the rotor 1. This water flows partly down through a spiral slot 69 in the bearing bush 24 and down within the conical bearing housing 17, through the thrust bearing and back into the shaft bore 62, and partly down outside the housing, through slots 66 in a securing ring 40, through holes 67 in the housing securing flange, to passages 33 in the skid-ring at the lower end of the assembly, where it is filtered and returns to the thrust bearing through holes 68. Other water flows past the radial holes 63 and emerges from similar holes 64 on the other side of the rotor. Part of this water flows between the rotor sleeve 59 and the stator to join the water emerging from the radial holes 63, whilst the rest of it enters the perforated winding sheath 56 and passes partly down the winding slots and through perforations in lower winding sheath 57 to join the stream outside the bearing housing 17, and partly up through holes 70, 71 in the flanges of the motor casing 10 and the top bearing housing 16 respectively to conduits 72 in the wall of the pump casing to cool the pump bearing. The bush of this bearing has passages for the flow of the water, but the bearing surface is kept dry by a carbon packing washer compressed by a circular spring clip. After leaving the passages in this bearing, the water flows down round the shaft coupling 58 partly into the shaft bore 62 by short radial holes 65 and partly through a baffle 91 and a spiral groove 76 in the upper bearing bush 20 to join the flow from holes 64. In the pump body, a porous plug (e.g. of sintered bronze) is held on a seating by spring pressure and thus allows water to escape due to thermal expansion by lifting the spring, replacement water passing through the porous element on cooling down. An insulating layer 82, 83, 84, 85, 86 separates the pump body from the motor. Specifications 623,363 and 623,364, [Group XXVI], are referred to.
