Filed: 1972-10-18
Abstract: 1395733 Laminated interlinings for garments KUFNER TEXTILWERKE KG 18 Oct 1972 [28 Oct 1971] 47950/72 Addition to 1335430 Heading B5N Stiffening interlinings for garments are produced by cutting or stamping the interlining or a portion thereof from a web of material having different degrees of stiffness in differing areas by virtue of it comprising two or more layers of material adhesively bonded together but only partially overlying each other, at least one of the layers of material having areas of differing characteristics and/or the or at least one of the adhesive layers having areas of differing characteristics whereby the sheet material has areas of differing stiffness. Where the layers are of woven material the varying consistency of one layer may be achieved by varying the density of the weave or quality of the yarn. Differing characteristics of the adhesive, which may be a polyacrylate, polymethacrylate or polyurethane, may be obtained by varying the pattern of the adhesive, the amount of adhesive or the elasticity of the adhesive. Where the layers are of woven material, an edge portion of a layer may be free from weft or warp threads. In Fig. 1, a heat sealable adhesive 2 is applied in the form of spots to the lower side of layer 1 to permit the lining material to be adhered to a garment, and layer 3 is adhered to layer 1 by a close network of spots of adhesive 4 and a more widely spaced pattern of spots 5 of adhesive. The layers may be of woven material, a fleece or foamed material. In an alternative construction the two layers are bonded together by means of a uniformly distributed network of spots but the upper layer, which is of woven material, is divided into two portions, one of which has a looser weave than the other.

Title: Improvements relating to heating filaments for indirectly-heated cathodes for electron tubes
IPC: H01J9/08
Filed: 1962-12-19
Abstract: 976,012. Cathode heaters. PHILIP'S ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 19, 1962 [Dec. 22, 1961], No. 47952/62. Heading H5H. A dark-coloured insulating layer is formed on a cathode heater by first coating the heating filament with a layer of pure aluminium oxide, and then soaking the coated filament in a solution of at least one alkali metal, i.e. Na, K, Li, Rb, Cs or the NH 4  group behaving as a metal, and one metal melting above 1500‹ C. e.g. W, Mo, Re, Ta or Cr, or compounds thereof, before heating in a reducing atmosphere. Apart from being a better heat radiator, an insulating layer so formed has an increased insulation resistance over a pure aluminium oxide layer. In particular, a tungsten filament may be wound on a molybdenum core, then coated with pure aluminium oxide which is sintered before dissolving out the core, and afterwards dipped in an aqueous solution of lithium molybdate and finally heated in hydrogen at 1600‹ C. Alternatively, the aluminium oxide layer is not pre-sintered, the coated filament and core being both dipped in an aqueous solution of lithium tungstenate and heated in hydrogen, before dissolving out the core. Specific examples are given.

Abstract: 968,486. Feeding sheets. MABEG MASCHINENBAU G.m.b.H. Dec. 27, 1962 [Dec. 27, 1961], No. 48612/62. Heading B6B. Apparatus for controlling the feed of sheets up to front aligning stops 8, 8<SP>1</SP> comprises main conveyer belts 2, and an auxiliary conveyer which travels at a slower rate than the main conveyer, and is disposed between the stops and the main conveyer. As shown, sheets 23 which overlap are fed over a table 1 by the belts 2 and driven pressure rollers 11, and are then fed into abutment with the stops 8, 8<SP>1</SP> at a slower rate by a pair of perforated belts 5 which co-operate with a suction box 4 having a separate suction chamber for each belt 5. Each suction chamber is connected to a pipe 14 having a rotary valve 13, 15 which is operable by a toothed segment 16 engaging a toothed armature 17 of a solenoid 18. Each solenoid circuit includes a current source 32 and a switch 10 or 101 which is controlled by one of two feelers 9, 9<SP>1</SP> arranged to be pivoted by the front edge of each sheet as it approaches the stops 8, 8<SP>1</SP>. If the sheet is correctly aligned as it reaches the belts 5, both belts grip and feed the sheet forwardly, and the feelers 9, 9<SP>1</SP> will be engaged simultaneously to cause the solenoids 18 to close the pipes 14 and cut off suction at the belts. If, however, the sheet is misaligned and one corner thereof engages the feeler 9, for example, the suction at the corresponding belt 5 will be cut off, whereas that at the other belt 5 will remain. Thus, the sheet will be skewed and straightened until both feelers 9, 9<SP>1</SP> are engaged, whereupon suction is cut off at both belts 5. In a modification (Fig. 3, not shown), the suction belts 5 are replaced by a rotating suction drum having two spaced suction chambers each controlled by a solenoid-operated rotary valve as described above.

Abstract: 1,186,453. Protective arrangements. M-O VALVE CO. Ltd., J. GOWAR, and K. G. COOK. 17 Oct., 1968 [3 Nov., 1967], No. 50182/67. Heading H2K. [Also in Division H1] A load 31 is protected from drawing excess current by a device 30 comprising anode 2, cathode 4, grid 3 and baffle 5 which normally permits the passage of an anode/cathode discharge but which obstructs the discharge when a magnetic field produced by coil 27 is present. Anode 2 is connected in series with load 31, a pulse generator 32 and with the power supply. Since grid 3 is normally held negative with respect to the anode the discharge in device 30 may only be started by applying a positive pulse across transformer 43. A pulse is produced from pulse generator 32 when the load current exceeds a predetermined value; this pulse fires a thyratron 35 causing capacitor 39 to discharge through coil 27 which produces a pulse of magnetic field, e.g. having a duration of 60 microseconds and a peak value of 1 kilogauss, sufficient to extinguish the discharge in device 30. The discharge remains extinguished until a positive pulse is once again applied to grid 3.

Title: An instrumentation for the automatic, simultaneous ultramicro determination of the c-h-n contents of organic compounds
IPC: G01N7/08
Filed: 1963-12-20
Abstract: 1,010,330. Analysing materials using catharometers. TECHNICON INSTRUMENTS CORPORATION. Dec. 20, 1963 [Dec. 28, 1962], No. 50297/63. Heading G1N. Apparatus for determining the C, H and N content of a substance by combustion and subsequent detection of the combustion products using a catharometer has the catharometer wires connected in a bridge circuit whose output feeds an integrator, and selectively operable means are provided at the bridge output for producing a first relationship between the flow of water vapour through the catharometer and the integrator input, and a second relationship between the flow of carbon dioxide and nitrogen through the catharometer and the integrator input. Helium carrier gas with a small proportion of oxygen is passed through a water absorption cell 18 to combustion tube 21 and part of the stream passes to a water column 32 for stabilising the gas pressure. A sample is placed in carrier 25a and is moved by magnetic member 25b into the part of tube 21 heated by oven 128. Combustion gases are carried by the carrier gas through a reduction tube 40, filled with copper, and a water absorbtion tube 44 containing silica gel. The remaining gases pass through the first cell 49 of catharometer 61 to a metal coil 50, sufficiently long to ensure complete combustion, and then through tube 53 packed with magnesium perchlorate and sodium asbestos to absorb water and carbon dioxide. The nitrogen which remains passes to the second catharometer cell 59. When the carbon dioxide and nitrogen measurements are complete silica gel tube 44 is heated by heaters 45 to expel the absorbed water which is then detected by the catharometer. The catharometer bridge feeds integrator 75 which includes a switch 53. In a first position, S 3a , switch S3 connects a resistor 124 and two zener diodes 126 in parallel with resistor 122 in the circuit of the generator of the integrator, during the determination of  CO 2  and nitrogen. In the second position, S 3b1 , S 3b2 , the switch activates the silica gel heater 45 and rearranges the connections in the generator circuit for the water determination. The integrator motor may activate a digital counter or digital printer. Operation of the apparatus may be manual, semi-automatic with the counter readings being printed, or fully automatic with the derivation of a signal indicative of the weight of the sample and the percentages of C, H and N being printed. The catharometer is mounted in a thermostatic chamber 62 heated by lamp 67 in conjunction with fan 69, and controlled by temperature responsive switch 65.

Title: Apparatus for Measuring Absorbance Differences
IPC: G01N21/27
Filed: 1966-11-10
Abstract: 1,168,815. Photo-electric absorption measurement. INSTRUMENTATION SPECIALITIES CO. Nov. 10, 1966 [Aug.2, 1966], No.50425/66. Heading G1A. Photo-electric apparatus for measuring the difference in absorbance (absorption co-efficient) between liquids contained in two test chambers 12, 12<SP>1</SP> comprises a pair of photo-electric detectors 13, 13<SP>1</SP> receiving light from a source 10, 11 transmitted through the test chambers, the detectors being connected in series and in such a way that the apparatus responds substantially logarithmically to the detected light intensities. Direct measurement of the absorbance difference is therefore possible since absorbance is logarithmically related to the transmitted light-intensity through a chamber. The measuring voltmeter is biased to operate in the linear part of the curve of voltage response against absorbance, Fig. 3 (not shown). If the photo-resistive type of detectors used, whose conductivity varies as the square root of the incident light-intensity, the detectors 13, 13<SP>1</SP> are connected in a bridge circuit in association with fixed resistors 17, 18, Fig. 1, so that the circuit responds logarithmically. The voltage across the bridge then gives an indication of the difference in absorption co-efficient detected between the two test chambers, one of which may act as a reference. In a modified circuit, Fig.4 (not shown), the voltmeter is connected across one of the detectors (13<SP>1</SP>) and the fixed resistors are omitted, the photo-resistors (13) modifying the response of the other (13<SP>1</SP>) to a logarithmic one. Semiconductor detectors, of the p-n junction type, may be used, Fig. 5 (not shown), being connected in opposition and responding logarithmically without the need for associated fixed series resistors. However, temperature compensation, unnecessary with the Fig. 1 circuit, is then required. The optical apparatus includes a source comprising a mercury vapour lamp 10 exciting a cerium-activated lanthanium fluoride phosphor coated on a transparent tube 11. Either ultraviolet light from the tube 11 at 280 mÁ or from the lamp 10 at 254 mÁ is directed to test chambers 12, 12<SP>1</SP>. Movable slide members 28, 28<SP>1</SP> with apertures 32, 32<SP>1</SP> and mirrors 33, 33<SP>1</SP>, 34, 34<SP>1</SP> provide for this choice. Movable slide members 36, 40 one having an aperture 37 and the other carrying absorption standards, are provided to enable calibration of the apparatus. Fluorescent filters 14, 14<SP>1</SP> are associated with the detectors 13, 13<SP>1</SP> to convert ultraviolet radiation, within the bandwidth of 245-290 mÁ into visible light to which the detectors can respond. Source construction In Figs.8, 9 (not shown), an elliptical cylinder reflector is used to focus light from the lamp 10 into the tube 11. A tungsten or hydrogen discharge lamp associated with suitable mono-chromator and filters may be used instead of a mercury lamp.
