Title: Improvements in and relating to the bonding of metals with rubber
IPC: C08J5/12
Filed: 1932-12-14
Abstract: Articles made of ferrous metals are first coated with a metal or alloy electropositive to copper, e.g. zinc, lead, tin, aluminium, cadmium or lead-zinc alloys, then coated with copper or a copper alloy such as a brass or bronze by chemical deposition, and then coated with rubber by vulcanizing a rubber coating in contact with the copper surface.  The coating of metal electropositive to copper may be applied by any suitable method such as hot dipping, electroplating, spraying, or cementation, the metal is then cleaned, e.g. in hot sodium carbonate solution, and then dipped in the copper-coating bath.  The following examples of copper-coating baths are given:-(1) a solution of cuprous cyanide, sodium cyanide, sodium carbonate, and sodium thiosulphate; (2) a solution of copper sulphate and ammonium oxalate; (3) an acid solution containing copper sulphate and sulphuric acid particularly suitable for coating an article which has been coated with lead; (4) a solution of copper sulphate, potassium tartrate, and ammonia for articles which have been coated with cadmium.  Salts of other metals such as silver, cobalt, tin, zinc &c. may be added to the copper baths to give alloy coatings. The process is particularly applicable to the preparation of wire for use as beads for pneumatic tyres.ALSO:Articles made of ferrous metals are first coated with a metal or alloy electropositive to copper, e.g. zinc, lead, tin, aluminium, cadmium, or lead-zinc alloys, then coated with copper or a copper alloy such as a brass or bronze by chemical deposition, and then coated with rubber by vulcanizing a rubber coating in contact with the copper surface.

Title: Process for producing acrylic composite fibres having woolly crimp  characteristics
IPC: D01F8/08
Filed: 1971-07-29
Abstract: 1309038 Composite acrylic filaments AMERICAN CYANAMID CO 29 July 1971 [26 Aug 1970] 35802/71 Heading B5B Side-by-side type bicomponent filaments are wet-spun from two polymers each containing at least 88 wt. per cent acrylonitrile, one having an "irreversible swelling index" at least 0À05 higher than, and a Young's Modulus at least equal to that of the other. The wet-gel filaments are washed, stretched and relaxed at 60-130‹ C. in water or steam while maintaining at least 40% water content, and are thereafter dehydrated, collapsed and finally stretched 1À02 to 1À20 x at 90-135‹ C., and crimped, whereby the said one polymer forms the inside component of the crimps. The second stretch is conducted at the temperature at which the filaments exhibit maximum shrinking force. The first stretch may be partially combined with the washing. Between stretchings the filaments may be heated tensionless at 80-130‹ C. in steam or water. The "irreversible swelling index" is W G /W D  where W G  and W D  are the respective filament weights after wet heat-stretching and after drying. The required 0À05 differential in this factor may be obtained by the following alternatives: (a) providing an acrylonitrile content differential between the polymers of at least 2%; (b) by providing a strong acid group content of up to 30 meq./kg. higher in the high shrinking component than in the other component; (c) by providing up to 10% more hydrophilic groups in the higher shrinking component than the other component; (d) by using spinning solutions of different concentrations (e.g. 0À3-5À0% difference) ; or (e) by using a polymer of lower M.W. for the high shrinking component. In examples, 97/3 and 92/8 acrylonitrile/methyl acrylate copolymers are used as high and low shrinking components respectively, each containing 50 meq./kg. of sulphonate (as Na methallylsulphonate) and are spun from 11% and 13% solutions in NaCNS into 10% aqueous NaCNS at 0‹ C.

Abstract: 966,095. Manifolding stationery; fastening sheets together. STANDARD REGISTER CO. Oct. 24, 1960, No. 36472/60. Headings B6A and B6P. A manifolding form assembly comprising record webs 1, 2, 3, and interleaved carbon webs 4, 5, is provided with feed perforations in its marginal edges and is characterized in that some of the feed perforations of an underlying web are formed by an incomplete circular cut, to form tongues 12, 13, which are struck through the perforations of an overlying web by the pin of a pin-feed device, to detachably hold the webs in register during feeding of the assembly. Some or all of the feed perforations of any or all of the underlying webs are formed with tongues, such as 12, 13. In addition, some or all of the feed perforations of the topmost web 1 may also be formed with tongues. The hinging portions of the tongues constitute 1/ 4  to 1/9 of the circumference of the feed perforations. The diameter of the feed perforations in the carbon webs is larger than that of the feed perforations in the record webs. Alternatively, the feed perforations in the lowermost web 3 are 0.002 to 0.003 inch larger in diameter than those in the overlying webs 1, 4, 2 and 5, to facilitate engagement of the tongues, which are formed in the lowermost web only, in the overlying perforations. The assembly is provided with transverse lines of weakening and is folded in zig-zag fashion to form a pack. The length of the carbon webs in the pack may be slightly shorter than that of the record webs. The width of the carbon webs may be such that they stop short of the marginal edges of the record webs containing the feed perforations.

Title: Improvements in or relating to apparatus for indicating the surface finish on the face of gear teeth
IPC: G01B5/28
Filed: 1956-11-30
Abstract: 817,797. Measuring surface roughness electrically. BRITISH PETROLEUM CO. Ltd., and BARCLAY, 1. DUFF-. Nov. 30. 1956, No. 36677/56. Class 40 (1). [Also in Group XIX] Apparatus for indicating the finish of a curved surface of a gear tooth comprises a roughness tester having an electrical pick-up stylus, a pivoted arm 2 holding the stylus by a clamp 18 in contact with a tooth surface and mechanism for traversing the stylus over the tooth surface, comprising a movable support 19 holding the gear against axial movement relative to the support 19 but allowing it to rotate and means (not shown) for imparting a part-rotational motion to the gear when the support 19 moves axially, the gear being held in the support with its axis at an angle to the line of movement of the support equal to the root angle. The pivoted arm 2 on pillar 1 can be clamped in position by screws 4, 5 and raised or lowered by a fine adjusting screw 3. This arm 2 carries a slider 6 which can be adjusted radially along the arm by a screw and nut 8, 7, the nut being spring loaded in order to protect the stylus during adjustment. A lever 12 pivots on a pin 11 and may be positioned by thumb screws 13, 14. A second lever 16 is hinged to lever 12 by a pivot pin 15 and can be adjusted by screw 17. This lever 16 carries the pick-up clamping unit 18. The support table 19 is mounted on three balls 20, each running in a separate Veeblock 21 secured to the base, and forming a three-point support for the table. The table carries two inverted Vee-blocks (not shown) and a hardened steel pad 24 to rest on the balls 20. An eccentric 29 driven by a hand wheel 30 operates through a multiplying lever 25 to impart oscillating movement to the table 19. Ball races 35, 36 on brackets 33, 34 support the pinion shaft at the required angle and spring= loaded races 37, 38 ensure that the pinion shaft seats firmly on the lower races during measurement. A clamp 42 held to the shaft by pads 43, 44 carries at its lower end a ball race (not shown) located in a helical slot in a guide plate 46. Thus as the table is oscillated, this clamp imparts a semi-rotary motion to the pinion. A plunger 49 in a housing 47 is used to locate the pinion for measurement on different teeth. In operation, the table is set at the mid-point of its travel and the plunger 49 inserted in the tooth gap diametrically opposite the tooth to be tested. A roughness tester, preferably of the type in which a crystal element generates a voltage which is a function of the motion of the stylus, is attached to the clamp 18 and brought into light contact with the tooth surface by adjustment of the various controls on arm 2. Hand wheel 30 is rotated and the longitudinal motion coupled with the semi-rotary motion moves the pinion so that the roughness tester indicates any surface irregularities.
