Title: Measuring apparatus for measuring the thickness of a strand and control apparatus
IPC: B65H63/06
Filed: 1964-01-10
Abstract: 1,024,127. Pneumatic testing. MONSANTO CO. Jan. 10, 1964 [Jan. 17, 1963], No. 1236/64. Headings G1M and GIN. Apparatus for measuring the thickness of a strand-like material comprises a block 24 having a first surface, a removable covering having a second surface mating with the first surface, a groove 22 formed either in the first or second surfaces providing a passageway for slidably receiving the strand, a fluid duct communicating with said passageway between the ends of the passageway, and means for fielding the strand to be measured through the passageway so as to partially block the passageway, whereby variations in the thickness of the strand vary the effective size of the passageway. The strand 20 is continuously drawn through the groove 22 in the block 24, the groove 22 being connected through five passages 116 to a passage 25 of a pneumatic bridge 30. The pneumatic bridge 30 consists of pipes 35, 37 and 42 controlled by valves 34, 36, 38, air from a pressurized source 40 being drawn through paths 35, 37 to the atmosphere at 30 or through the groove 22 respectively. A balance sensing tube 42 is situated between passages 35, 37 and encloses a pair of heated thermocouple junctions 50, 52 separated by an unconnected baffle plate 56 supporting the cold junction 54. Junctions 50, 52 are connected through conductors 66, 68 to a control device 32. The baffle plate 56 is orientated at an angle of 45 degrees to the axis of tube 42 so that air flowing through the tube will cause one of the heated junctions to be cooled more than the other. In use, the bridge 30 is balanced using a standard strand 20. During subsequent testing, as the strand is fed through the groove 22, variations in the width of the strand result in varying air currents flowing through the tube 42, causing unbalance of the hot and cold junctions. The resultant signal is then fed to the control device 32. The device measuring apparatus may be incorporated with a spin-draw system (see Fig. 8, not shown).

Filed: 1958-01-16
Abstract: 821,799. Regulating. NORDBERG MANUFACTURING CO. Jan. 16, 1958, No. 1568/58. Class 7(6) In an engine having an exhaust driven supercharger 43, Fig. 2, the time of opening of the exhaust valve 7 is advanced as the engine load decreases and simultaneously the fuel supply is controlled so that the fuel quantity at lower loads is greater than the normal quantity would be in the absence of variation of the valve timing. The exhaust valve 7, Figs. 1 and 2, abuts against a plunger 10 actuated by hydraulic fluid from a pressure main 120 under the control of a shuttle valve 16 which is actuated by hydraulic fluid from a pump 21. The valve 16 is raised on the pump delivery stroke to permit hydraulic fluid to flow through pipe 15 to open valve '7 and returns when the pump stroke ends to exhaust fluid through pipe 18 and permit valve 7 to close. The beginning and end of the delivery stroke of pump 21 are controlled by helical control edges on the plunger 260, which is rotated through a control rack 240 by a governor 35 so that the beginning and ending of the pump delivery stroke, and hence the opening and closing of the exhaust valve 7, are advanced as engine load decreases, whereby the exhaust gases are maintained at an adequate pressure at reduced loads to maintain operation of the supercharger. The control rack 240 of the hydrauic fluid pump 21 is also connected to the control rack 36 of the fuel injection pump 37 which is controlled so that the normal fuel supply curve XYZ, Fig. 6 is altered to XYZ<SP>1</SP>, giving a greater fuel supply than normal at lower loads.

Abstract: 823,499. Laminating glass sheets. PITTSBURGH PLATE GLASS CO. Jan. 20, 1958 [Feb. 14, 1957], No. 1839/58. Class 140. In a process of making laminated assemblies of pairs of curved glass sheets for windshields &c. in which the pairs of sheets are bent simultaneously in a mould at softening temperatures and subsequently separated for the insertion of a layer of plastic such as polyvinyl butyral and then reassembled for laminating under pressure and heat, accurate registration of the sheets after reassembly is secured by applying to the inner surface of one of the sheets before moulding a pair of spaced spots of a composition which stains both sheets at the moulding temperature. As shown the spots 14 are applied close to one edge of that part 10 of the assembly which is only slightly curved and close to the wings 12 which are more sharply curved; in the finished laminate they are covered by the frame. The spots are about 0.002 inch in thickness and may comprise coloured enamel, glass frit, or paper soaked in salts such as lithium salts which produce etched markings. Preferably, however, they comprise compositions made by grinding silver chloride and copper sulphate (in proportions within the range 2: 1 and 6: 1), yellow ochre, a dispersion liquid such as alcohol and a thickener such as pine oil. Such a composition may be applied as drops or, with the addition of polyvinyl butyral, may be sprayed on to transfer paper, small moistened discs of which are applied to the glass and the paper backing remover. Alternatively a similar composition having an added wax may be applied through a metal stencil screen electrically heated to the melting point of the wax.
