Title: Method of producing an ultraviolet resistant polycarbonate article
Inventor: OSTEEN MITCHELL MONROE
IPC: C08J7/06
Filed: 1965-03-26
Abstract: An article consisting essentially of a polycarbonate resin of intrinsic viscosity greater than 0.40 decilitres per gram in p-dioxane at 30 DEG C, the formation of which is described, is coated with an ultraviolet absorbing compound, e.g. benzophenones and substituted benzatriazoles, to resist degradation by ultraviolet light.  The coating is applied by dipping the article into a bath containing a dispersion of an ultraviolet absorbing compound in water at 90 DEG  to 100 DEG C.  The ultraviolet absorbing compounds may be 2,2\sv dihydroxy-4,4\sv dimetoxy-benzophenone; 2,2\sv,4,4\sv tetrahydroxy-benzophenone; 2,4 dihydroxy-benzophenone; and 2(2\sv-hydroxy 5\sv-methylphenyl) benzotriazole.  The ultraviolet absorbing compound may be suspended in the water bath in a cotton fabric bag.  Oxalic acid may be added to the dispersion if iron is present in the water.  The article may be in any shape, e.g. a luminaire refractor or lens, and may be an unfinished article such as sheet material so long as the coating is not disturbed by any further operation, e.g. cutting or mechanically shaping.  The article may contain blue tint and an ultraviolet absorber before treatment.

IPC: D05B27/10
Abstract: 132,845. Barrett, S., and Henshilwood, A. B. Sept. 14, 1918. Chain - stitching machines; feeding long lengths of fabric; spool-holders. - A chain-stitch sewing machine for stitching together the selvedges of a long length of fabric which is folded longitudinally prior to fabric finishing operations is provided with a special guiding arrangement for ensuring that the two selvedges may be kept straight and even over each other and at equal tension. The thread tension is also maintained constant. Fig. 1 shows a front elevation of the machine and Fig. 3 a plan of the guiding arrangement. The cone 8 of stitching thread is carried on a spindle 9 driven from a grooved pulley 11 moved into gear with the driving shaft of the machine by a forked lever 7 only when the sewing-machine is to be worked. The stitching thread is thus only paid out as the machine is worked. The thread tension is controlled by a delicately-shaped supporting spring 14 through one of the loops b of which the thread passes. In addition to this and instead of another similar guide 14b, where necessary another tension spring 15 is provided. The guiding arrangement comprises a slotted arm 19 extending in front of the machine. The fabric passes through slots f, g, and its position is regulated by an adjustable guide 20 which slides along the arm 19 and is fixed bv a screw 21. Another slotted arm 22 is mounted behind the arm 19 so that it can be oscillated on a bearing pin 23 by the attendant moving a handle 22a when it is required to adjust the tensions of the two selvedges. A further guiding arm 25 is mounted behind the arm 22 of a length equal to that of the slot in the arm 22. A supporting roller 26 for the fabric is provided.

Filed: 1975-04-01
Abstract: 1502375 Waterproofing cables WESTERN ELECTRIC CO INC 1 April 1975 [4 April 1974] 13368/75 Heading D1L The interstices of a stranded core of a communications cable are filled with a waterproofing compound in apparatus comprising, as shown in Fig. 3, a pressure relief chamber 31, a filling chamber 32, a second pressure relief chamber 33 and a cooling chamber (not shown) through which the cable core is advanced in sequence, the filling chamber 32 being connected by feeder pipes 117 to supply manifold 121 containing the waterproofing compound under pressure. The filling chamber 32 contains a tubular filling member 112 with orifices 114 therein so that the water proofing compound therein is directed in an upstream direction of the advance of the cable core. This flow due to the orifices 114 combined with the flow due to the advance of the cable core and the pressurisation of the waterproofing compound supply causes the compound to flow longitudinally of the cable in the direction of travel, opposite thereto and also inwardly of the longitudinal axis to displace therein within the interstices and so fill the interstices with compound. The pressure relief chambers 31 and 33 contain pressure resistant seals to the cable core to provide equalisation of pressure between the filling chamber 32 and the atmosphere and allow surplus compound to be returned via chains 107 to the supply manifold 121.

Abstract: 837,066. Fluid-pressure servomotor control systems; valves. TECNOS INTERNACIONAL COMPANIA ANOMINA. April 28, 1958, No. 13401/58. Class 135. Upon depressing or tilting the spring-loaded button 8, Fig. 1, of a water fountain, an auxiliary valve 4 is unseated releasing the water pressure in a chamber 3 above a flexible, e.g. rubber, valve closure 13 and enabling water in the inlet 10 to lift the central part of the closure 13 and place the inlet in communication with a number of outlets 11 that open into a delivery tube 12; the centre of the closure 13 lifts slowly since the water displaced thereby flows into chamber via an orifice 16. When the button 8 is released the valve 4 reseats but water continues to enter the chamber 3 by inlet 10, a groove 14 or an aperture through the closure, not shown, and orifice 16 until the pressure differential across the closure 13 is sufficient to urge the latter on to its seat 9. The orifice 16 is provided in a plate 15 which is formed with peripheral teeth 17 that abut the closure 13; the plate 15 may be spaced from the closure 13 to allow the latter to lift fully in operation. The orifice 16 is of smaller section than that controlled by the valve 4 but larger than the section of groove 14. In a modification, the auxiliary valve is comprised by a remote gate valve 28, Fig. 3, which when opened allows the closure 13 to slide upwardly so connecting the inlet 10 with the delivery tube 12 by outlets 11; a gasket prevents the closure 13 from contacting the orifice plate 15. The closure 13 embodies an aperture 25 or may be grooved as in Fig. 1. This construction is applicable to domestic faucets, and the conduit 27 leading to the valve 28 is connected to drain or the tube 12. The closure 13 seats when the valve 28 is again closed. In a final modification, the apparatus is disposed in a flush tank 37, Fig. 4, and upon emptying the latter a float 50 falls and causes rotation of a bonnet 43 on transverse stub pins and hence tilting of a bar 48 integral with the bonnet, which bar in turn tilts the stem 6 of the auxiliary valve 4 and opens the latter thus enabling the main closure 13 to bulge as in Fig. 1, or to slide upwardly in the chamber 3 and permit water in the inlet 10 to flow into the tank 37 via outlets 11 and a splash tube 38 that opens near the tank bottom to ensure silent filling of the latter. As the tank fills the float 50 is raised and finally closes the valve 4 whereupon the main closure reseats. Water flowing past the valve 4 is directed into the tank outlet pipe and assists in the flushing operation. The valve closures may be of moulded nylon.

In a variable-speed transmission for winding devices and the like, shafts 1, 2, which are interchangeably driving or driven, carry cone pulleys 3, 4 and 5, 6 between which an open link chain 7 transmits torque. The pulley flanges 4, 5 are fixed to their shafts and the flanges 3, 6 are axially displaceable. The hubs of the flanges 3, 6 have cam paths 11, 13 and 17, 19 respectively between which lie rolling bodies 12, 18. The cam paths 13, 19 are formed in sleeves 15, 21 rotatably disposed on the shafts 2, 1 and secured against axial displacement by flanges 14, 20; the sleeves 15, 21 each have toothed rims 16, 22, axial components of the torque being produced by the cams and rolling bodies 12, 18 to cause the pulleys 3, 4 and 5, 6 to grip the chain 7. Additional contact pressure, independent of the load, is produced by weights 24, 29 displaceably and fixably arranged on stationary levers 23, 28, the ends of which have cams 25, 30 acting upon pressure rolls 27, 32 arranged in pivoted double levers 26, 31 which transmit the weight, as a controlling force, to the flanges 3, 6. The sleeves 21, 15 adjust themselves with respect to the hubs of the cone pulleys according to the magnitude of the transmitted torque and thereby produce changes in the relative spacing of the pulleys. The contours of the cams 25, 30 and the adjustment and size of the weights 24, 29 can be varied so as to obtain any desired regularity of the transmission ratio for both winding and unwinding operations. Of the two weightactuated pressure devices 23-27 and 28-32, that associated with the driven shaft is normally disconnected.
