Title: Improved manufacture of pneumatic tyres
IPC: B60C5/14
Filed: 1931-03-27
Abstract: 368,544. Wheel tyres. GOODYEAR TIRE & RUBBER CO., 1144, East Market Street, Akron, Ohio, U.S.A. March 27, 1931, No. 9409. Convention date, May 31, 1930. [Class 144 (ii).] A method of making pneumatic tyres comprises shaping rubberized fabric material into tyre form, lining the inner surface of the shaped tyre form with vulcanizable material and lapping the material about the bead portions of the tyre, inserting a sleeve of vulcanizable material axially into the central opening of the tyre, and securing the end portions of the sleeve to the lapped portions of the lining. As shown in Fig. 2, a tyre carcass 17 is formed by applying a strip 12 of rubber compound to a drum 11 and superposing a ply 13, the end portions of which are folded inwardly along lines 14, and a tread 18. The carcass is then slid from the drum and after its edge portions are shirred upon the bead elements 19, Fig. 2, it is shaped as shown, for example, by means of an air bag. Annular strips 20 of rubber compound then have their ends stitched on the edges 22 of the strip 12 and the bead portions 23 of the carcass respectively. A cylindrical sleeve 24 of uncured or partially cured rubber compound, having a valve stem secured therein, is stitched on the portions 23a of the strips 20 and a curing hub 27, with removable flanges 28, inserted therethrough, the whole being placed in a mould and the rubber vulcanized. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which a opartially vulcanized inner tube is inserted within the carcass 17 and after the curing hub 27 has been positioned as in Fig. 2, the carcass and inner tube are vulcanized together. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in web-feeding mechanisms
Inventor: JOHNSON REGINALD FRANK
IPC: B65B41/16
Filed: 1960-03-17
Abstract: 961,294. Feeding webs. ROSE BROS. (GAINSBOROUGH) Ltd. June 15, 1961 [March 17, 1960], No. 9425/60. Heading B6B. A feed roller 14 is driven through differential gearing by a driving shaft 26, the differential  gearing being adjustable, by movement of a tension member 17, in response to variations in length of a web loop, to adjust the speed of the roller 14. The feed roller 14 is freely mounted on a shaft 23 and carries a sun gear 28 in mesh with planet gears 29 mounted in a yoke 31 secured to the shaft 23. The gears 29 engage a ring gear 32 having external ratchet teeth 33 for engagement with a pawl 34 and a spring-loaded looking pawl 36 which holds the gear 32 when not being driven by the pawl 34. The pawl 34 is pivotally mounted on an arm 37 connected by a link 38 to one of a pair of arms 18 carrying the roller 17. A shield 39, Fig. 1 (not shown) normally prevents engagement of the pawl 34 with teeth 33. The roller 14 cooperating with a roller 13 normally feeds a slightly insufficient length of web 11 to intermittently driven rollers 22, such that the loop around roller 17 decreases, thereby causing pawl 34 to move beyond the end of the shield 39. The pawl 34 then rotates the ring gear 32 to increase the speed of roller 14. Alternatively, a solenoid energized by a switch operated by arms 18 may actuate the arm 37.

Patent GB-828360-A (GB)
Title: Improvements in yarn control means for textile machines
Inventor: HELD JOSEPH
IPC: D04B27/00
Filed: 1957-03-22
Abstract: 828,360. Variable-speed gear. TEXTILE MACHINE WORKS. March 22, 1957, No. 9522/57. Class 80 (2). [Also in Groups VIII and IX] The speed of rotation of the warp beam of a textile machine is automatically controlled through variable-speed driving-means so that the linear speed of the warp remains substantially constant. To this end the warp passes over and rotates a roller which through a chain- and sprocket 215 drive rotates a shaft 191, Fig. 17, carrying a bevel gear 195 forming part of a differential 189. The gear 206 forming the opposed bevel gear of the differential is integral with a worm gear 207 and is rotatable about the shaft 191. Initially the speed of the gear 206 is set in relation to the desired linear speed of the warp through the worm drive deriving its motion via variable-speed driving means from the main shaft of the machine. This latter variable-speed driving means which is of the same construction as that for controlling the speed of rotation of the beam is adjusted by hand to obtain the required setting and speed of gear 206. Consequently, therefore, any variation between the speeds of the gear 206 and gear 195 due to the warp driven roller varying its speed of rotation, causes the intermediate bevel gears 201 of the differential, which are coupled by a yoke 190 to a hub portion 187, to revolve and turn a sprocket-wheel 186 secured to portion 187. The sprocket 186, through a chain drive, rotates a shaft 161, Fig. 10, having a threaded portion 160 carrying a nut which engages a fork 156 of a lever 152. Movement of the shaft 161 causes the lever 152 to pivot a partspherical member 92 which is freely rotatable and resiliently urged into engagement with two friction discs 87, 120 for transmitting the drive from one to the other. The disc 120 is rotated at a constant speed by gearing driven from the main shaft of the machine and which gearing also serves to drive the corresponding disc of the variable-speed drive for the gear 206 serving as the normally constant speed gear of the differential. The pivoting of the member 92 therefore varies the ratio of the drive between the two discs 120 and 87 and accordingly the speed of rotation of the beam is varied, the beam being coupled through worm gearing to the shaft carrying the disc 87. To disengage the drive between the discs of both variable-speed driving means a shaft 262 is turned by hand so that toggle joints formed between arms 261 secured to shaft 262 and other arms 257 mounted on the pins supporting the part-spherical members, raise the part-spherical members out of engagement with the discs. The shaft 161 has a handwheel 167 which may be drawn outwardly against a spring to disengage the drive from the differential so that the shaft 161 may then be turned by hand to readjust the setting of the variable-speed driving member 92 after, for example, a new beam has been installed on the machine.

Title: Process for converting optically active aminodiols into racemic aminodiols
Filed: 1956-03-27
Abstract: In a modification of the process of the parent Specification for converting the D-erythro or L-threo form of 1-p-nitrophenyl-2-amino-1 : 3-propanediol to the DL-threo form, the p-nitro-a -acylaminoacrylophenone obtained as an intermediate in one form of the process is converted by an addition reaction with a lower (1-4C) aliphatic alcohol to a DL-p-nitro-a -acylamino-b -alkoxypropiophenone, which is reduced to a mixture of DL-threo- and -erythro-1-p-nitrophenyl - 2 - acylamino - 3 - alkoxypropan - 1 - ols, these are separated and the erythro compound epimerized into a further amount of the threo isomer, and the said racemic threo-1-p-nitrophenyl - 2 - acylamino - 3 - alkoxypropan-1-ol is converted in known manner into DL-threo - 1 - p - nitrophenyl - 2 - amino - 1 : 3-propanediol.  The addition reaction is advantageously effected in the presence of a preferably warm alkaline catalyst (e.g. an alkali metal hydroxide or alcoholate, an alkali metal salt of a weak acid, or a tertiary amine), and the reduction by means of an alkali metal borohydride or an aluminium alcoholate in the presence of excess of the alcohol.  Separation of the threo and erythro forms of the reduction product may be accomplished by fractional crystallization, e.g. from water, a lower aliphatic alcohol or a mixture thereof.  The epimerization of the erythro compound may be effected by treatment with a dehydrating agent, optionally in the presence of an inert diluent, at 0-25 DEG  C., followed by treatment with cold dilute alkali to form the DL-threo-1-p-nitrophenyl - 2 - acylamino - 3 - alkoxypropan - 1 - ol, or, according to a further modification, with warm water to give a salt of DL-threo-1-p-nitrophenyl - 2 - amino - 3 - alkoxypropan - 1 - ol, from which the base is liberated with alkali and may be converted to DL-threo-1-p-nitrophenyl - 2 - amino - 1 : 3 - propanediol by prolonged heating with mineral acids.  In an example, the acylamino group is acetylamino, methanol is used in the addition reaction in the presence of sodium acetate, sodium borohydride as reducing agent, water as the solvent for the fractional crystallization and SOCl2 as the dehydrating agent in the epimerization step.  The acylamino group is formulated general as RCONH- where R is an alkyl, haloalkyl, aryl or aralkyl group or hydrogen.
