Title: Improvements relating to electric glow discharge cells
IPC: H01J17/04
Filed: 1955-07-08
Abstract: 772,333. High-frequency discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. July 8. 1955 [July 15, 1954], No. 19869/55. Class 39(1). A sheet of mica is placed in a T.R. bell to act as a reservoir for water vapour. During operation the mica is bombarded by ionized particles and liberates water vapour to compensate for excess due to oxidation of the walls of the cell. The cell shown comprises an envelope 2, which may be of copper, resonant windows 3 and 4, and resonant circuits 5 and 6 each comprising a pair of cones 7, 8 or 9, 10 and a pair of vertical fins 11 or 12. Cone 9 is open at its apex and surrounds an auxiliary electrode 13. A sheet of mica 14 of length slightly greater than the height of the envelope 2 is retained by its own elasticity in position adjacent the window 3. The cell may be mounted in the duplex structure of a radar aerial between a waveguide 15 and a waveguide 16 connected to the receiver. Energy in the waveguide 15 produces an ionic discharge across the window 3 and the mica 14 is bombarded by ionized particles. In an alternative embodiment a mica sheet of length slightly greater than the width of the envelope 2 extends across the cell near the window 3 between the vertical walls of the envelope.

Abstract: 1,072,592. Binding coils. BOTALAM (a Ltd. Co.). May 11, 1965 [May 11, 1964], No. 19886/65. Heading B8C. Coils are bound by a machine which includes means 32 for transferring coils from a conveyer 1 to the binding position, and further means for returning the coils after binding to the conveyer. In the embodiment described the coils are removed from the conveyer by a hook 36 carried by arms 35, 32 which are luffed by rams 37, 33 and which can slue about a bearing 29 to deliver each coil to a roller 15. The coils are returned to the conveyer by a similar mechanism symmetrically disposed (Fig. 2, not shown). The roller 15 is mounted on a luffing arm 17 so that it can lower the coil to a position where a binding is applied by jaws 6, 7. The roller 15 is rotated between bindings by a motor 21. The conveyer 1 may operate at a higher rate than the binding machine, the coils missed by the binding machine being dealt with by further similar machines. The coils may be conveyed in a plane at right angles to that of Fig. 1. The machine may be controlled automatically.

Filed: 1936-07-20
Abstract: 471,626. Sewing-machines. ROBERT, R. C. July 20, 1936, No. 20098. [Class 112] The body of the rotatable element of a vertical axis rotary hook is of truncated conical form with a large open base and a cavity for seating the bobbin. The spindle 1 of the hook is rotated by bevel gears 3, 6. The conical body 4 of the hook is secured to the spindle by a screw 5. The truncated conical body 4 forms a flat bottomed cavity 8 with a seating 8<1> for the bobbin support 13. The body is cut as at 9, Fig. 9, to balance the opening 10 forming the hook 10. A leaf spring 12<11> guides the needle thread to the hook. The surfaces are of tempered steel and can operate at high speeds without being oiled. A leaf spring 19 is secured to the curved arm 18<1> on the crown 17 of the bobbin support 13, to regulate the tension of the bobbin thread. A cushion 19<111> on this spring prevents the needle thread loop from becoming entangled with the bobbin thread. The bobbin 25 is held in the carrier 13 by an articulated tongue 26.
Patent GB-628072-A (GB)
Title: Methods of making organo-siloxanes
IPC: C08G77/06
Filed: 1947-07-25
Abstract: A mixed organo-siloxane is prepared by hydrolysing a mixture of compounds of the formul  C6H5.CH3.Si.X2, (CH3)2.Si.X2 and C6H5.Si.X3, where X is a readily hydrolysable group such as a halogen atom, or alkoxy group.  Hydrolysis may be effected by the dropwise addition of water, preferably dissolved in from 2 to 4 volumes of a common solvent such as alcohol, dioxane, acetic acid or acetone, followed usually by subsequent heating to complete dehydration.  Where the mixture contains both a chloride and esters, the former may be converted to an ester by the slow addition of dry alcohol thereto, or to the mixture diluted with dioxane.  The hydrolysis products, after removal of solvent and excess water, are water-immiscible liquids soluble in benzene and toluene and may be thermoplastic, thermosetting or thermally stable.  In an example, ethyl alcohol was added to a solution of C6H5.CH3.Si.(OC2H5)2, (CH3)2.Si.(OC2H5)2 and C6H5.Si.Cl3 in the molecular proportions of 1 : 1 : 3 and water added in slight excess.  After boiling off solvents the viscous oil gave a hard film after heating at 190 DEG  C. for 48 hours.

Title: Measuring devices for bores and ducts
IPC: G01B7/28
Filed: 1974-05-08
Abstract: 1495754 Measuring pipe bores UNDERGROUND LOCATION SERVICES Ltd 23 April 1975 [8 May 1974] 20303/74 Headings G1M and G1N A measuring device for a bore or duct comprises a fluid-filled rubber envelope 11, pressure transducers 16-19 for sensing pressure variations within the envelope and a rubber cup 12 for forming a piston, in, for example, a pipeline along which the device is driven by fluid pressure. Dents in the pipe wall cause variations in pressure in the envelope which unbalance a bridge, Fig. 2, formed by transducers 16, 17 and a second pair 18, 19 sensing pressure in the pipe. The bridge output is fed via a differential amplifier 24 and Schmitt circuit 25 to a monostable multi-vibrator 26 which triggers only on fast rise-times of the input waveform. The output of multi-vibrator 26 triggers the printer 30 to print the output of counter 29 and via a second multi-vibrator 31 resets the counter 29. The counter 29 counts the number of revolutions of a wheel 21 the mounting 22 of which includes a sensor 27 responsive to a magnet, cam, or light reflector on the wheel. The counter may include an arithmetic unit for converting the number of pulses into metres. Instead of using a printer 30, the outputs of multi-vibrator 26 and pulse shaper 28 may be continuously recorded. A further wheel 21 may be mounted on the housing 10 to engage the opposite side of the pipeline bore. The outputs of the two sensors are connected to a logic circuit which provides an additional pulse if, due to wheel slip, two successive pulses are received from the same sensor. In a second embodiment, Fig. 4 (not shown) the rubber envelope is a tubular toroid (53) which is inflated to a slightly smaller diameter than the  associated rubber cups (44, 49 and 51) so that it is not subject to abrasion.
