IPC: G01M3/38
Filed: 1952-03-01
Abstract: 733,348. Detecting leaks in vessels. INFRA RED DEVELOPMENT CO., Ltd. March 2, 1953 [March 1, 1952], No. 5445/52. Class 106 (2). [Also in Group XL (b) ] Vessels are tested for gas tightness by setting up between the inside of the vessel to be tested and the inside of a test chamber enclosing the vessel or enclosed by it, a difference in pressure of a gas having a high specific absorbtion in the infra-red spectrum and, after an interval, connecting the space in which the gas was originally at the lesser pressure with an analyzer in which the presence and amount of the gas is ascertained by its specific absorption of infra-red radiation. In Fig. 1 a collapsible chamber 1 houses a container 4 to be tested. The container 4 is filled with nitrous oxide to a pressure of, say, 5 lb. per square inch above atmospheric pressure and, after an interval, the chamber 1 is connected to an analyser 3 through a valve 2 and the volume of the collapsible chamber 1 is reduced in a manner transferring a definite fraction of its gas content to the analyser 3. The dial 6 may be graduated as desired. The analyser 3 may have two chambers traversed by intermittent infra-red beams, the gas to be tested having access to one compartment whilst the other compartment contains a standard gas, the infra-red beams being absorbed in detector chambers .containing gas of the kind. to be detected, in this case nitrous oxide; the detector chambers are separated from each other by a diaphragm which yields to the difference of pressures resulting from absorption, the movement of the diaphragm serving to vary the capacity of an electric condenser in an electronic circuit. In a modification, Fig. 2, the containers 4 are housed in rigid chambers 7 that are evacuated by temporary connection through a valve 8 to an exhaust pump. After an interval, to allow for any leakage, the chamber 7 is connected to the analyser 3 and the latter through a cock 9 to an exhaust pump so that a part of any gas that has leaked from the container 4 is drawn into the analyser 3.

Title: Bar system in schlieren-optical systems
IPC: H01J29/56
Filed: 1959-02-18
Abstract: 863,925. Light-modulating devices. GRETENER A.G., E. Feb. 18, 1959 [Feb. 25, 1958; July 24, 1958], No. 5677/59. Class 40(3) [Also in Group XX] In a Schlieren optical reproducing system using spaced bars such that light from a source impinging on surfaces of the bars is normally reflected from a controlled surface on to the bar surfaces but is deflected to pass to a varying extent through the spaces between the bars in response to variations of the controlled surface corresponding to the light variations of the picture image to be produced, the reflecting faces of the bars are disposed in different planes in such manner that when viewed from the light source, the gaps or distances between the faces appear to be less than the distances across or dimensions of the faces, whereas when viewed from the controlled surface, the gaps between the faces appear to be approximately of the same width as the faces. Preferably the gaps, when viewed from the light source are arranged to be extremely small so that the bar reflecting surfaces appear to be almost continuous. Light from a source 10 backed by a concave mirror 12 is focused by lenses 14, 22 on to the bar system and light reflected by the surfaces of the bars 16 is normally reflected back from the surface of a controllable deformable layer 19 to the sufaces of the bars 16. The surface of the layer 19 mounted on the concave mirror 20 is scanned by a cathode beam 32 from a gun 28 so that variations of the beam 32 produce corresponding deformations of the surface of layer 19 and deflections of a light beam to pass through the gaps 40 to a lens system 32 and via a mirror 34 to a viewing screen 36. The envelope 26 for the cathode-ray scanning device is sealed by a glass plate 38 disposed to minimize light loss by internal reflection. As shown in Fig. 3 the surfaces 52 of the bars 50 are non-coplanar or staggered, and when viewed in the direction of the arrows appear as an almost continuous surface, as indicated in Fig. 4 (not shown). Viewed from the deformable surface, the gaps 40 appear to have a width equal to that of the reflecting surfaces 52. The bars 50 are formed with rearward bevels 62. In a modification of Fig. 1, Fig. 2 (not shown), using a plane deformable member having its surface scanned by a cathode-ray beam, two bar systems are employed, the bars of one of which being disposed to reflect light under normal conditions from the constant source to the bars of the second system, through the gaps of which light is diverted when the surface of the deformable member is scanned by the cathode beam of varying intensity. An arrangement with two bar systems may be associated with a modulation layer on a concave reflector, as described in Specification 808,841. Specification 678,307 also is referred to.

Reeling - machines; doffing-arrangements; thread-holding and threads e v e r i n g arrangements; driving- arrangements; stop-apparatus, non- automatic; tension - arrangements; stop-motions.-Skeins of thread, wool &c. k, Fig. 14, comprising a number of simple loops or turns maintained in position by paper sleeves k, one end k<2> being free so that a length may be cut off without disturbing the remainder, are wound on holders f, Figs. 2 and 15, the turns being accommodated in a fork f<4> and upon a finger f<9> which latter is turned to release the wound skein, the thread being traversed by guides f<5> on a bar f<6> actuated by a cam f<7>. The sleeves k are placed on the skein by hand before the latter is withdrawn from the machine. The winding and doffing portions of the machine are driven respectively by the side elements of a differential, one side being held when the other is free, the mid-element of the differential being driven through pinions m<3>, m<4>, Fig. 6, from a countershaft m<1> itself driven through a friction-clutch m<2>. The skein-holders are driven through ball friction-clutches g<5> - - g<9>, Fig. 13, which slip when the winding is unduly obstructed, and are geared to wind a predetermined number of turns before being automatically stopped by the measuring-disc l<4>. During winding the lever m<6> is held by the stop m<8>. On completion of winding the bar m' is automatically moved to hold the winding-side and permit the doffing-side to function. The clutch m<2> is first automatically released by a cam n<5> to stop the machine. The tickets or bands k are then applied and the handle n<3> depressed to reengage the clutch m<2>. The thread is then cut by a blade h<4>, Fig. 17, and the supply end held by retaining members h<1>, h<3>, Fig. 15, in readiness for the next skein. The holding and cutting devices are actuated by a tappet h<5> on a bar h<6> driven by a cam h<7>, Fig. 2, while the tappet f<12> releases the bar f<9> to permit withdrawal of the skein. After banding the skeins are gripped by pincers k<3>, k<4>, Fig. 5, on spindles k<33>, k<44>, withdrawn automatically through the action of links k<11> controlled by a cam, and deposited on a conveyer l. The thread passes through a tensiondevice i comprising two spring-pressed discs i<1> normally separated by a wedge i<2> , Fig. 5, the latter being removed prior to cutting so that the thread is held more firmly.

Abstract: 1,158,572. Glass manufacture. NIPPON GLASS CO. Ltd. 4 March, 1966 [4 March, 1965], No. 5760/66. Heading C1M. A process for producing glass from batch consisting essentially of silica, sodium carbonate and limestone comprises pulverizing the batch materials, mixing the pulverized materials together, pelletizing the mixture, drying the pellets, adding cullet thereto and charging the mixture of pellets and cullet into a melting furnace to melt the same and wherein the pulverized material is less than 40 mesh (defined), at least 65% by weight of which is less than 100 mesh and the silica is less than 40 mesh at least 60% by weight of which is less than 100 mesh. A suitable glass batch was, in parts by weight, Silica 100, Soda Ash 30, Limestone 30, Glaubers Salt 1. After mixing and pelletizing, the pellets were dried for 30 minutes at 600‹ C. and then electrically melted. Melting times varied from 75 minutes at 1250‹ C. to 15 minutes at 1400‹ C. to get a melt free from all silica residues. Another example gave a batch in which caustic soda replaced some of the soda ash, and was in parts by weight : Silica 100, Soda Ash 24, Caustic Soda 7.5, Limestone 30, Glaubers Salt 1, Potassium Bicarbonate 0.03, Cobalt oxide 0.005, Carbon 0.08. They were dried at 550‹ C. after pelletizing and melted as before. This latter glass was blue. Several tables show the proportions of grain sizes for different examples.

Abstract: 411,984. Claw clutches. AUBIN, E., Elmstead, West Wittering, near Chichester, Sussex, and CLAREMONT, A. W., Vernon House, Sicilian Avenue, Bloomsbury Square, London.-(Representatives of ROYCE, Sir F. H.) Feb. 25, 1933, No. 5830. [Class 80 (ii).] In order to obviate the tendency of a claw clutch to disengage due to axial thrusts resulting from misalignment or from twisting of the splined shaft under torque, the movable member d<2> of the clutch is secured on a flange f<1> of an inner sleeve f<2>, at a part substantially removed from the plane of clutch engagement and in such a way as to permit a slight universal movement of the member d<2>, by means of short splines e, f and split rings h mounted in grooves in the member d<2>, and the sleeve f<2> is in splined engagement with its associated driven or driving shaft a, the splines g, g<1> in the sleeve being separated by an annular gap and the position of these splines and the nature of the sleeve being such that the load on the splines g, g<1> is equalized. Where, as shown, the member d<2> forms a double clutch sleeve, the splines g, g<1> are arranged on opposite sides of and equidistant from the flange f<1>, the sleeve f<2> being throughout its length of not greater torsional stiffness than the shaft a and being of less torsional stiffness at that end nearer to the point at which the shaft transmits or receives the drive. Where, however, the member d<2> forms a single clutch sleeve, the splines g<1> may be directly beneath the splines f, the splines g being nearer to the clutch claws, in which case the sleeve f<2> is throughout of the same stiffness as the shaft. Projections on the member d<2> co-operate with a flange j<1> in the sleeve f<2> to assist in supporting the member d' when in the disengaged position.

Abstract: 1,176,424. High frequency inductors; circuit assemblies. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. 8 Feb., 1967 [24 Feb., 1966], No. 6106/67. Headings H1R, HIT and H1W. A high frequency variometer includes at least one inner conductor 9 constituting part of an arcuate or spiral winding housed in an outer box conductor 17 to which it is connected at one end by a fixed connection which includes a resistor of value approximately equal to, or equal to one half of, the characteristic impedance of the screened, asymmetrical conductor device constituted by the two conductors, and a movable short-circuiting contact device 10a, 10b movable along the length of the inner conductor and arranged to connect a variable point thereon to the outer conductor. As shown, the anode of a valve 3 of a telecommunication transmitter is connected through a blocking capacitor 8 and strip conductor 25 to the input end of the inner conductor 9, rotation of arm 21 permitting variation of the electrical length of the conductor 9 in the circuit by movement of the rollers 10a, 10b which short-circuit the conductor 9 to a counter conductor (not shown) of similar geometry which is connected to the outer conductor 17 over its entire length. To suppress resonance effects in the out-of-circuit portion of conductor 9 either the resistor 16 may be chosen approximately equal to the characteristic impedance of the device, and be connected to conductor 9 through a # filter 20 passing upper harmonics of frequencies in the higher part of the operating frequency range, or-if the electrical length of the out-of-circuit portion of the conductor 9 never substantially exceeds #/4 for the highest operating frequency - by dispensing with the filter and choosing resistor 16 to have a value of about half the characteristic impedance. Both the conductor 9 and the counter conductor can be in the form of tubes through which coolant is circulated, and the capacitance of the filter 20 can be in the form of a water path in an insulating tube.
