Abstract: 1379593 Photo-electric flaw detectors AGFA-GEVAERT 10 May 1972 [21 May 1971] 16348/71 Heading G1A [Also in Division H4] Apparatus for investigating defects in a moving sheet consists of a plurality of photosensitive devices which receive radiation after reflection from or passage through the sheet, each device being coupled to an amplifier filter unit which has automatic gain control to help an average output at a predetermined level and is arranged to provide an output when the amplified input signal from the device is greater than the average output. As shown in Fig. 2, each part of the width of the moving sheet 14 has on one side a light source 13 and on the other side, to receive the transmitted radiation, a plurality of phototransistors 20 each connected through an amplifier 21 shown in Fig. 3, to a summation amplifier 22, analogue to digital convertor 18 and a data logger 23 which feeds a recorder 24. The quiescent state of amplifier 21 may be checked and adjusted by means of selector switch 50 and voltmeter 51. Amplifier 21 consists of an operational amplifier 31 connected in series with filters formed by capacitors 30, 33 38 and resistors 32, 37 and a detector circuit consisting of diodes 34, 35 which will only conduct signals greater than a pre-set level. The gain of the amplifier 31 is charged by altering the feedback impedance presented by field effect transistor 47. The output signals from amplifier 31 pass through diode 40 and are compared at the input of amplifier 43 with the voltage from an adjustable source 45 to alter the conduction of transistor 47. An RC circuit 41, 42 ensures that transient signals do not pass to the comparator.

Class 64(1) [Also in Group XI] The lower end of the combustion chamber 1 of an instantaneous gasfired water-heater of the balanced flue-type is provided with sealing means, such as a narrow skirt 13 containing asbestos string packing, to seal that end of the chamber to the upper part of a box 12 containing the burners. Furthermore, this burner box is sealed to combustion-air inlet-ducting 11 which passes down behind the combustion chamber 1 in spaced relationship thereto. The duct 11 is of rectangular section and is supported by brackets 30 if the heater is mounted in a cupboard, or a casing may be clipped over the appliance The hot gases pass up through the combustion chamber 1 and through a heatexchanger 2 to an outlet flue 10. The gas flow is controlled in a section 3 beneath which is mounted a section 4 for controlling the water flow from an inlet pipe 5 to a pipe 6 coiled on the combustion chamber up to the heat-exchanger 2. Inlet and outlet sections 32 and 33, of a terminal unit secured to the outside of the wall on which the heater is mounted, pass through apertures, with serrated edges to reduce thermal conduction, in a wall plate 31 and connect to the inlet duct 11 and flue 10. Where the wall is a cavity wall, apertures in the plate 31 may permit cooling air to circulate around the sections 32, 33. The air and combustion-gas flow-circuit is sealed from the room atmosphere by a panel 15 screwed to the front of the burner box 12 and carrying a detachable plate 17 having a glass observation window and a knob 20. Rotation of the knob stores and releases energy in a spring to rotate a wheel on a flint and produce sparks for lighting the gas burners (see Group XI). Electric ignition may be employed. The Provisional Specification describes also ignition by means of the pilot burner and a flash tube on a pivoted finger plate covering an aperture in the burner box. Reference is also made to the casing comprising a back plate and to the inletducting being in one piece.

Title: Improvements in or relating to the treatment of cinematograph films
IPC: G03D15/00
Filed: 1937-06-14
Abstract: 486,360. Renovating kinematograph films. STOCK, F. J. J. June 14, 1937, No. 16610. Convention date, June 19, 1936. [Class 98 (ii)] The marginal perforated region of developed and fixed films, more especially those of non- inflammable or slowly-inflammable material, are treated separately to incorporate softening agents therein in a manner known per se. The films may be treated over their full width, in a manner known per se, prior to or after the marginal treatment, with softening agents which swell the film to restore it to its condition when raw. A solution of substances of greater strength when solid than the film material, and equivalent physically and chemically to the film material, may be applied to the film in its swollen state to form a protective layer homogeneously united with the film surface. As softening agents may be used camphor dissolved in acetone acetic ether for celluloid films ; and for acetate films, triphenylphosphate, phthalic acid ester or phosphoric acid ester, dissolved in acetone, acetic ether or methylene chloride. For applying the liquids, the film may be led successively over three rollers which dip into baths of the liquids, and are provided with reduced peripheral portions so that the first applies softening liquid to the perforated region, the second applies the same liquid to the remaining region or to the whole width, and the third applies the protective coating. A solution suitable for the combined swelling, coating, and impregnating of a celluloid film may consist of a nitrous cellulose ester of low viscosity such as pyroxylin, shellac, and camphor, dissolved in alcohol and acetic ether. The processes described in Specifications 230,154 and 243,752, [both in Class 98 (ii)], are referred to ; and also a process for applying to a film a polyglycol and then a quick-drying cellulose ester composition ; and a process for applying to a film a coating solution containing collodion, sulphuric ether, methylated spirit, and either formic acid, glacial acetic acid, or acetic ether.

Title: Improvements in glands for shafts rotatable at high peripheral speeds
IPC: F16J15/40
Filed: 1947-06-23
Abstract: 916,150. Stuffing-box substitutes. GENERAL ELECTRIC CO. Ltd., and LE ROSSIGNOL, R. June 22, 1948 [June 23, 1947], No. 16515/47. Class 122 (5). A gland for a shaft member rotatable at a high peripheral speed comprises two like surfaces of revolution (one being that of the shaft member) arranged with a small clearance between them, one of the surfaces being provided with helical or spiral grooves extending from a central region to connect with the two sides of the gland between which substantial sealing is required, the central region being sealed from the outside ends of the gland excepting through the grooves and the clearance between the surfaces; the senses of the helices or spirals and the arrangement being such that when the shaft member is rotated in the appropriate direction at a suitable speed a vacuum is produced in the central region. In Fig. 1 a shaft member 10 coupled to the main shaft 15 by a bellows device 16 runs within a cylindrical outer gland member 11 in which are formed two helical grooves 12, 13 of opposite hand extending from a central region where a ring 14 separates the two grooves. When the shaft member 10 rotates it operates like a Holweck pump, gas in-the region of ring 14 being pumped outwards along the grooves 12, 13 respectively to the space to the left of members 10 and 11 and through a threaded hole 21 in the wall 20 across which the seal is desired. When the pressure to the right of wall 20 is atmospheric, a rough vacuum may be produced by an auxiliary pump connected with the hole 21. To provide a seal when the shaft is not rotating a rubbing gland 23 of metal or graphite may be pressed against the right-hand ends of members 10 and 11 and is preferably actuated automatically when the speed of the shaft drops below a predetermined value. A cup-leather gland 22 prevents oil flowing from the journal bearing and through the ball bearing to the low pressure space. In another arrangement, Fig. 2, the cylindrical member 10 is replaced by two discs 26, 27 which run in passages formed in ports connected to the wall 20 and provided with spiral grooves 28, 29, 30 and 31. A close clearance ring is provided at 32. The directions of the spirals and of rotation are such that gas in the space 33 is pumped outwards along groove 29 and inwards along groove 28 to emerge at 36 on the left of wall 20; similarly gas in space 34 is pumped along grooves 30, 31 to the hole 21.

Abstract: 546,455. Thermal switches. SHEPHERD. G. R. (Westinghouse Electric International Co.). Nov. 15, 1940, No. 16538. [Class 38 (v)] [Also in Groups XIII and XL] In a glow discharge bimetallic switch which may be used for initiating a discharge between the electrodes of a discharge lamp, ,and in which a glow discharge between two electrodes of which one at least is bimetallic and provided with electron emissive material causes the electrodes to move together into engagement, the second electrode has a surface area considerably less than that of the bimetallic electrode so as to increase the effective resistance of the glow discharge which will start when the electrodes again separate. This will increase the voltage 'kick' disc to the inductance in main circuit and which starts the discharge lamp working. The pressure of the gaseous medium in the envelope of the switch is also kept below 30 mm. of mercury to increase the resistance of any arc between the electrodes. Fig. 4 shows one form of switch, 20 being the bimetal electrode which carries a contact 22 and a strip of electron emitting magnesium and 19 being the other smaller electrode. Fig. 5 shows a modification in which the bimetal strip has a backing of magnesium and is provided with holes 25 where the most intense discharge and heating occurs. In other modifications, the bimetal strip is corrugated and backed by a straight magnesium strip.

[Also in Division D1] In the production of a fleece from a card 1 having cross-laying means 2, the uniformity of the fleece is measured by a sensing device 32 and balanced against a preset nominal weight for the fleece whereby the drive of the card and the drive of the delivery table are controlled in such a way that the velocity of the delivery table, in relation to the velocity of the laying table is adjusted in accordance with an even number of layers in the fleece. The variations in thickness and weight in the fleece are transmitted by the device 32 to a measuring installation 56 and balanced against a set weight indicated by a potentiometer 53; the deviations are shown on a recorder 57 which is provided with manually operated push buttons 51 or with automatic switches so that electrical impulses are transmitted to a servomotor 36 to effect a change in velocity of the delivery table 22 and thereby either increase or decrease the weight of the fleece per unit area. The crossing angle 2 α of the fleece as it is deposited on the delivery table is proportional to the ratio of the velocities of the delivery table and the laying table. The number of layers in the finished fleece is limited in a downward direction by a maximum crossing angle. The velocities of the laying and delivery tables are measured and the relevant quotient measured in a device indicating the crossing angle, the device having a displaceable limit switch which actuates a step switch which regulates the servomotor 36 to reduce the velocity of the delivery table by an amount which produces an increase of two layers in the fleece. The laying width of the fleece may be varied automatically or by manual control. If two or more cards are coupled together with crosslaying means, uniformity measuring devices 78, 79 are provided for each cross-laying means, Fig. 5 (not shown).

Title: Improvements in or relating to supercharging systems for aircraft cabins
IPC: B64D13/04
Filed: 1941-12-30
Abstract: 554,417. Fluid-pressure servomotor-control systems. BENDIX AVIATION CORPORATION. Dec. 30, 1941, No. 16805. Convention date, Dec. 31, 1940. [Class 135] [Also in Groups X and  XXXIII]  An air supercharging system for a pressure cabin in an aircraft is provided with means for maintaining a constant pressure and a constant rate of change of air within the cabin, a valve in an air exhaust member in the air inlet conduit being responsive to changes in the rate of flow of cabin air. It comprises two regulators, one 57 maintaining a constant pressure in the output of the supercharger 14 and the other 21 controlling the rate of air flow into and out of the cabin 10. Air is scooped into a flared inlet 13 of pipe 11 from which leads a byepass 17 controlled by a valve 19, and a pipe 20 from a venturi 16 to regulator 21. An exhaust pipe 12 from the cabin is provided with a throttle valve controlled by regulator 21, and with a valve 26 mounted on an aneroid member 25. Pipes 30 and 58 connect the cabin with regulators 21 and 57 respectively. Flexible " Sylphon " (Registered Trade Mark) chambers 59, 64 are separated by a partition 63 connected by a pivot 67 and arm 66 with a piston valve 69, 70 which co-operates wi'h ports 72, 73. These ports open into a servomotor cylinder 74 in which moves a piston 79 connected by a rod 80 and members 81, 82 with valve 19. Valve members 69, 70 normally close ports 72, 73, but, if the pressure in the cabin falls, Sylphon 64 contracts and the valve moves to the position shown allowing oil under pressure from pipe 76 to pass through port 72 and move piston 79 to the right, so that, by the connections shown, the valve 19 is closed, allowing more air to flow into the cabin. Regulator 21 acts in a similar fashion. As the rate of flow into the cabin increases due, for example, to punctures in the wall, the pressure at throat 16 decreases, the " Sylphon " device 31 moves to the left carrying valve rod 39, oil passes from pipe 50 through port 44 and moves piston 47 in servomotor cylinder 46 to the right, closing outlet valve 23. If the cabin is badly punctured, valve 23 is fully closed and regulator 57 closes valve 19 completety. Safety valves 84, 85 open, either when the internal pressure in, or the external pressure on, the cabin exceeds the predetermined amount.

A shaft 1 turnably supported in a bracket 2 has a splined arm 3 for connection to a controlled member, surface or valve and has extending therethrough a tubular body 5 containing a lock shaft 7 supported at the respective ends thereof by a fitting 6 and a nut 8 engaging a transversely extending spring support bar 9. A compensating spring 10 surrounding the shaft 7 is compressed between the bar 9 and a locking crosshead 11 provided with a hub 12 slidable on the shaft; the crosshead extends outwardly from the hub to outer spring-guide tubes 15, 15<SP>1</SP> connected to the bar 9 and surrounded by compression springs 17, 17<SP>1</SP> and the crosshead is connected by links 18, 18<SP>1</SP> to sectors 20, 20<SP>1</SP> turnably supported on the shaft hub 4 and having anchored thereto control lines 23, 23<SP>1</SP>. Attached to the sector 20 is a surge lock body 25 containing a rotor 28 which, together with a thrust ring 31, has depressions 29 for the reception of balls 30, the outer surface of the ring 31 having serrations 33 for engagement with opposing serrations 33<SP>1</SP> on the body 25. The ring 31 is urged toward the rotor 28 by a spring 32 surrounding the rotor hub 26 which carries a pinion 34 that meshes with a gear segment 35 fixed to the sector 20<SP>1</SP>. During normal compensating action of the regulator should the cables contract or expand the springs 10, 17 and 17<SP>1</SP> expand and contract to permit such action and the sectors 20, 20<SP>1</SP> turn in opposite directions with respect to one another causing movement of the pinion 34 along the rack 35 which causes the rotor 28 to rotate within the body 25 and the spring 32 holds the ring 31 against the balls 30 to retain the latter in the depressions 29. Should the tension on one cable be increased while the tension on the other cable is slackened a greater force is applied to one of the springs 17, 17<SP>1</SP> and the crosshead turns slightly upon the shaft 7 causing the hub 12 to bind on the shaft to prevent further deflection of the springs so that the regulator is locked and acts as an ordinary sheave. Breakage of a cable causes excessive angular acceleration between the sectors 20, 20<SP>1</SP> and turning of the gear segment 35 drives the pinion 34 to rotate the rotor 28 when the balls 30 ride out of the depressions 29 to force outwardly the ring 31 whereby the serrations 33 thereon lock against the serrations 33<SP>1</SP> on the body 25 thereby immediately stopping relative turning of the two sectors and converting the regulator to a rigid member.
