Title: Latex Foam Rubber Process
Inventor: APPS ANDREW JOHN
IPC: B29C67/24
Filed: 1966-10-01
Abstract: 1,157,657. Foaming latex. DUNLOP CO. Ltd. 2 Oct., 1967 [1 Oct., 1966], No. 43976/66. Heading B5A. [Also in Division C3] Articles of latex foam are made by feeding a vulcanizable rubber latex foam composition containing a delayed action gelling agent and a gel controlling agent into a mould having a sealing gasket permeable to air but impermeable to the composition, closing the mould, reducing pressure in the mould until it is filled by the composition, gelling, releasing the vacuum and vulcanizing the composition. The rubber cornposition preferably contains one or more natural or synthetic rubbers, the snythetic rubber preferably being a butadiene-styrene copolymer or polyisoprene. The gelling agent is preferably sodium silicofluoride and the gel controlling agent one of potassium chloride, disodium hydrogen orthophosphate, potassium hydroxide and non-ionic surface active agents. In the preferred method as described, the latex composition containing conventional additives such as sulphur, fillers, accelerators, antioxidants and foaming agents is stored for about a day at 15-30‹ C. and is then whisked to at least 1À5 times its original volume. The delayed action gelling agent and optionally a second gelling agent such as diphenylguanidine are then added. The foam is charged into a mould, the mould being at a temperature of 4-20‹ C., the mould is sealed with wadded paper which is permeable to air but not to the foam and the pressure inside the mould is reduced to less than 120 mm.Hg. The temperature is raised to 35-65‹ C. for 5-10 minutes to allow the foam to gel and is then raised to 90-120‹ C., the vacuum is released and this temperature is maintained for 15-30 minutes to vulcanize the foam. During the last five minutes of the vulcanization the mould is sealed to prevent the material from drying out. The mould is then cooled to 35-65‹ C., retained at this temperature for at least one minute and is then cooled to room temperature and the article removed. To aid removal of the finished article the mould may be coated with a 4% aqueous solution of polyethylene glycol or the rubber composition may contain an aqueous solution comprising hydrogen peroxide and a sodium alkyl sulphate and/or a condensate of ethylene oxide with a fatty alcohol.

Title: Method and apparatus for measuring surface characteristics of  metals and metalloids
IPC: G01N27/20
Filed: 1971-09-22
Abstract: 1355231 Measuring surface properties of metals and metalloids M ENSANIAN 22 Sept 1971 [8 Oct 1970] 44257/71 Chemical and physical irregularities in the surface of a metal or metalloid are detected by measuring the magnitude and polarity of the voltage generated by a cell comprising a test electrode, a self sustaining body of electrolyte and a small area of said surface. The electrolyte may be carried by saturated absorbent discs or gelatine pellets. As shown in Fig. 3, a non- conductive tape 43 carries absorbent discs (45) saturated with electrolyte and is wound on, one disc at a time, from a supply spool 42 to a takeup spool 48. A trigger and ratchet (not shown) or a spring motor (not shown) may be used to advance the tape. In Fig. 14, the electrolyte is held in tyres on wheel electrodes which roll over the surface being tested. The wheels may have radial protrusions Fig. 13, (not shown). Alternatively Fig. 10, (not shown) the electrolyte carrier may be the entire wheel, the electrode serving as the axle. The tyres Fig. 14 or wheels Fig. 10, (not shown) may be made of felt or woven fabric, paper, wood, natural or synthetic sponge, or porous ceramics saturated with electrolyte, or gelatine or other gelling agent (long list given) mixed with electrolyte. Chemical details of electrodes and electrolytes. The test electrode, or a removable working tip, may be made of the same metal or metalloid as the surface under test, or may be made of a chemically resistive metal, e. g. Pt, Au, Pd, Ta, or graphite. The electrolyte is preferably a soluble salt of the metal being tested, e. g. iron sulphate or aluminium sulphate, but may be a soluble salt of another metal higher in the electro-motive series, e.g. Kcl may be used with Fe or Al electrodes to test iron or aluminium surfaces respectively. Also Li, Na, Ca salts may be used. The concentration of the electrolyte is not critical and may be in the range from 0À000M to 1M. When testing alloy surfaces, e. g. copper-tin (bronze), readings may be taken using a Cu electrode and a Cu salt electrolyte and Sn electrode and Sn salt electrolyte and compared. Both readings may be taken simultaneously, using the apparatus of Fig. 14, alternate wheels being characterized by different metals. Applications. Impurities and corrosion may be detected. Heat treatments or welds may be evaluated. The test surface may be hot, cold, polished or unpolished, and may be that of a casting or a wire or may be a vacuum deposited or plated coating. Sheets and springs may be tested before, during and after bending and tensioning respectively.

A device for sensing the feed of superposed sheets comprises gauge means positioned adjacent a reference member, and supported on a rotatable frame mounted on a base member whereby means are provided to adjust the spacing between the gauge means and the reference member; and a limit switch which is operated whenever the gauge means is disturbed by a superposed sheet to divert the superposed sheet from the normal feed path. Sheet-forming means (Fig. 4).-The apparatus is particularly suited to a xerographic copier (Fig. 1, not shown), in which sheets from a pile are fed to conveyer belts 414 entrained about a drive roller 417 and an idler roller (420) which is provided with a larger diameter index portion 422 along a part of its length. Sheets are fed through the gap between the index portion 422 and a sensor shoe 510, and are maintained on the belts by vacuum means, the belts 414 and vacuum shoe 408 having co-operating apertures connected to a vacuum source. Sheet-diverting means.-When superposed sheets are detected (see below), the sensor shoe 510 actuates limit switch LS-9 (Fig. 6) which, in turn, de-actuates solenoid SOL-3 and rotates shaft 427 against a spring (429) (Fig. 3, not shown) thus rotating reject fingers 426 through the spaces between belts 414 and breaking the vacuum, to allow the superposed sheets to drop into a receiver tray. Sheet-sensing means (Fig. 6).-The sensor shoe 510 is fixed to a shaft 513 which rotates in bifurcated portions of a frame member 520 which is itself rotatable on shaft 521 mounted in the base 530 of the sensing means; the frame 520 is biased into contact with an adjusting cam 540 which is mounted on shaft 541 also mounted in the base 530. An eccentric 550 is rotatably supported on shaft 551 mounted in the frame 520, rotation being supplied by worm-gear 553 and spur-gear 522; a lever 542 also serves to rotate the cam 540 relative to the eccentric 550 to alter the spacing between the sensor shoe 510 and index portion 422. If a superposed sheet is fed sensor shoe 510 is rotated anticlockwise (as seen in Fig. 6) by the sheet and arm 512 actuates limit switch LS-9, thus operating the reject fingers 426 through solenoid SOL-3.
