Title: Improvements in inner tubes for wheel tyres and method of manufacture
Filed: 1941-05-28
Abstract: 546,741. Rubber compositions making air tubes for wheel tyres. UNITED STATES RUBBER CO. May 28, 1941, No. 6846. Convention date, Aug. 3, 1940. [Classes 70 and 87 (ii)] [Also in Group XXXIV] A self-sealing air tube 40, Fig. 7, is provided in the tread portion with a cellular layer 24 integrally bonded with the tube wall and retaining in the cells a plastic sealing composition, with an inner layer 34 of rubber bonded with the cell walls and a further inner layer 35 of tacky rubber composition. The cellular layer is formed by placing a sheet of plastic vulcanizable rubber composition on a mould 22, Fig. 3, having upstanding round pins 21, and covering the sheet with a steel plate which is subjected to pressure to force the material into the mould cavities. The mould and material are then placed in a refrigerating chamber and chilled to about minus 20‹ C., when the solidified cellular layer or, grille may be peeled away from the mould. After it has assumed normal temperature the grille is placed on a layer of fabric 28, Fig. 5, and a layer of the plastic sealing composition is placed over it and softened by the pressure and heat of a metal plate so as to fill the cells. The composite grille is covered with the layer 34 of vulcanizable rubber and the layer 35 of rubber of the same composition as the plastic filling, and then placed against the inside surface of the rim part of an air tube cut open circumferentially and mounted on an inflated rotatable mandrel 45, Fig. 6. The buffed parts 41, 42 of the tube are coated with rubber cement and when dry are pressed down on to the cellular strip with the cut edges abutting, and a rubber strip 49 is cemented to the outside of the joint. The tube is then removed from the mandrel, inflated and placed in a mould and vulcanized. The cellular laver thus becomes bonded to the tube and the layer 34 in part vulcanized to the cell walls, while the plastic filling and the tacky layer 35 are unaffected. The plastic filling and the tacky layer may consist' of a composition of rubber, resin oil, and hydroquinone, and the layer 34 may consist of rubber, hydroquinone, an accelerator (triethyl trimethylene triamine), zinc oxide, zinc laurate and resin oil.

Title: Improvements in or relating to apparatus for testing the magnetic properties of materials
IPC: G01R33/14
Filed: 1944-04-17
Abstract: 575,856. Magnetic measurements. ELLIOTT BROS. (LONDON), LTD., and HAWKES, H. D. April 17, 1944, No. 7065. [Class 37] The in-phase and quadrature components of the magnetizing current applied to a sample of magnetic material are separately measured over a range of flux densities. The sample to be tested is in the form of a closed magnetic circuit such as a ring 1 wound with two windings 2, 3. The winding 2 is arranged to be connected to an A.C. supply 4 in series with either a winding 5 of a mixing transformer or with a resistance 6 of equal value. A phase-shifting apparatus 7 is also connected to the supply 4 and to three potential dividers 8, 9, 10 connected either in series, as shown, or in parallel. Windings 11, 13 on the mixing transformer are connected to the potential dividers 8, 9 respectively through a condenser or inductance 12 and a resistance 14. The potential divider 10 is connected to the winding 3 on the sample 1 through a resistance 15. A winding 16 on the mixing transformer is adapted to be connected to a detector 17, which is arranged to be alternatively connected across the resistance 15. An instrument 18 measures the current in the potential dividers 8, 9, 10. The winding 2 is connected to the A.C. supply 4 through the resistance 6 and causes an E.M.F. to be generated in the winding 3. The detector 17 is connected across the resistance 15 and the phase-shifting apparatus 7 and the potential divider 10 are adjusted until a null reading is obtained, indicating that the E.M.F. in the winding 3 is balanced by the E.M.F. across the potential divider 10, which may be calibrated in volts for a particular current through'it. Tne flux density in the sample 1 may then be determined from the voltage generated in the winding 3 and the dimensions of the sample. The winding 2 is then disconnected from the resistance 6 and connected to the winding 5, the detector 17 being connected to the winding 16, the setting of the phase-shifting apparatus 7 being left undisturbed. The potential dividers 8, 9 are adjusted until zero reading is obtained on the detector 17, indicating that the flux produced by the winding 5 in the magnetic circuit of the mixing transformer is balanced by that due to the windings 11, 13. At this balanced condition the winding 5 is non- reactive and the phase relation between the supply voltage and the current in the winding 2 is unaffected. The currents in the windings 11, 13 are proportional to the components of the exciting current in the winding 2. The potential dividers 8, 9 may be calibrated to read these currents directly with a known current passing through the circuit 18, 8, 9, 10..

Abstract: 766,448. Holders for thermionic valves; sliding contacts. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 25, 1955 [March 12, 1954], No. 7355/54. Class 38 (1). In a coaxial line structure comprising concentric tubular members 18, 19 carrying rings of resilient contact fingers 7 for engaging the contact rings 6 of a valve 1, the valve is supported on a tubular member 4 movable inside member 19. An annular piston- 8 with helical contact springs on its inner and outer peripheries is movable longitudinally between members 4, 19 for tuning the circuit, the piston being driven by threaded-rods 20 moved up and down by nuts incorporated in gears 25 rotated by a handle 9 through gears 10, 24 (or a chain). This mechanism is also used for withdrawing or inserting the valve by the provision of spring-loaded plungers and catches 11, 12 fixed respectively to the piston 8 and supporting plinth 22. With plunger 11 withdrawn and plunger 12 engaging a hole in member 4, members 4, 19 are held in fixed relationship so that rotation of handle 9 only varies the tuning. With plunger 11 engaging a hole in member 4 and plunger 12 withdrawn, suitable rotation of handle 9 draws member 4 (and the valve) downwards until an abutment 13 raises the valve from its seat whereupon it may be removed through a door in member 19. The valve is reinserted by a reversal of this procedure.
