Title: Improvements in pneumatic tyre
IPC: B60C9/00
Filed: 1960-02-26
Abstract: 870,479. Pneumatictyres. UNITED STATES RUBBER CO. Feb. 26, 1960 [April 24, 1959], No. 6777/60. Class 144 (2). In a pneumatic tyre having a breaker assembly comprising plies 18, of parallel metal wires, overlying the crown region of the carcase 10, the breaker assembly is itself overlaid with a layer 23 of rubber stock reinforced with a random dispersion of metal wire fragments, which may be steel of 0.006 inch diameter in lengths of from to 2 inches, the layer 23 extending beyond the edges of the breaker assembly into the shoulder regions 14 of the tyre. As shown, the carcase 10 comprises a plurality of textile parallel cord plies crosslaid with a cord angle in the range 38 to 41 degrees, and the breaker assembly comprises two cross-laid plies of parallel steel wires having a cord angle of 35 to 38 degrees. A rubber cushioning strip 22 having thickened side edges insulates the breaker assembly from the carcase and a further strip 24 of rubber tread stock separates the breaker assembly from the wire-reinforced layer 23. The layer 23 tapers towards each side edge, and as shown in Fig. 4, may have tongues 23a at each side which extend beneath the breaker assembly and taper towards the tread centre. The layer 23 may extend into the radially inner portion of the sidewall.

Abstract: 927,955. Welding by pressure. TELEGRAPH CONDENSER CO. Ltd., and J. W. PURSE. Jan. 29, 1962 [Feb. 24, 1961], No. 6819/61. Class 83 (4). [Also in Group XXXVI] In a welded joint between a wire and a metal foil the welding exists solely between one or more raised areas on the wire and the area of the foil in contact with the raised areas. A wire 3, Fig. 1, is deformed between an anvil 1 and a recessed block 4 to provide a flattened end 6 having bumps 7 thereon. The wire is then placed in a grooved electrode 9, Fig. 2, and a metal foil 10 is welded to the bumps by an electrode 11, short duration alternating current or condenser discharge being employed. A series of upper electrodes may be used or a single electrode may weld the spots in turn.

Title: Improvements in or relating to type bar mechanism for typewriters with segment shiftdevice
IPC: B41J7/02
Filed: 1949-03-14
Abstract: 676,969. Typewriters &c. TRIUMPH WERKE, NURNBERG AKT.-GES. March 14, 1949 [Oct. 1, 1948], No. 6873/49. Class 100 (iv). In a type-lever mechanism designed for uniform key-stroke in both lower and upper case printing positions the key-lever 14 actuates, through a connecting rod 13, an intermediate bellcrank lever 12 mounted on a supporting bracket 15 horizontally displaceable along a guide pin 20 by a cam member 23 supported on an arm 6 controlling the movement of the type segment 4 from a shift key 27 through a connection bar 28. The shift-key 27, shown in the depressed position, Fig. 2, draws the bar 28 downwardly and pivots the arm 6, which is the lower of a pair of parallel arms 5, 6 carrying the type segment 4 for vertical case-shift movement. Type-levers 3 are pivotally carried on a spindle 2 and are operated by a link 10 extending from a pivot 9 and connected at 11 to the bell-crank lever 12 operated by the connecting rod 13 attached to a key-lever 14. When the case-shift key 27 is operated the rod 13 is moved to the right by a distance " a " through a vertical plane v to compensate for the different position of the pivot 9 in the caseshift position. This rightward movement is effected by the action of the cam member 23, Fig. 3, adjustably attached to the arm 6, which when moved for case-shift engages a roller 25 attached to a bracket 17 carried by the supporting bracket 15. The bracket 17, which is guided by rollers 18, 19 on the pin 20, is thus moved rightwardly along the guide pin 20 against the tension of a spring 26, Fig. 2, which returns the bracket 15 after the key 27 is released, into engagement with an adjustable stop 30.

Title: Improvements relating to Flax Pulling Machines.
IPC: A01D45/06
Filed: 1917-05-16
Abstract: 116,522. Fibre Corporation and Michot, G. May 16, 1917. Flax-pulling machines.-Relates to flax-pulling machines of the type in which rotary drums are employed, provided with pulling-combs which are alternately protruded from the drum to engage the flax and retracted into the drum to release the pulled flax. Fig. 4 shows the framing of the drum with the means for operating the pulling combs. The drum, which may be circular or polygonal, is shown in the figure as square, and consists of metal plates secured to skeleton frames a<3> at the ends. The frames a<3> are mounted on a fixed cranked axle b. The combs, which consist of tapered teeth i<3>, are pivotally attached to brackets i<2> on the ends of connecting-rods i mounted on the cranked portion b<2> of the fixed axle b. The combs work through slotted bars h pivotally mounted in the frames a'. The rotation of the drum causes the combs to be alternately protruded and retracted as shown in Fig. 4. As shown in Fig. 1, the drum may consist of sections a, a<1> set at an angle to each other so that the pulling shall be progressive. When the drum is made in two or more sections, a circular plate a<2> is fixed between each section to act as a divider on the unpulled crop. The cranked axle b is secured to an inverted U-shaped frame b<1> supported on the main axle c at each side of one of the main carrying-wheels e. The drum is driven by gearing g, g<1> from a counter shaft f<2> mounted in the frame b'. The shaft f<2> is driven by gearing including a clutch from a countershaft f which is itself driven by gearing from the main axle c. The frame b<1> can be tilted on the axle c to adjust the working height of the drums from the ground by means of an adjustable stay k attached to the frame b<1> and to the pole d<1> to which the horses are harnessed and which is pivoted on the main axle c. The pulled flax, when it leaves the drums a, a<1>, is delivered upon endless conveyers indicated at l, l<1> in Fig. 1. These conveyers deliver the flax upon a transverse conveyer, (not shown), at the end of which is a counterweighted cradle from which the crop may be intermittingly deposited on the ground or removed by hand or passed to a binding mechanism. The conveyers are all mounted on wheeled frames attached to the machine, and are driven by belt gearing from the axles of the wheels.

Patent GB-471908-A (GB)
Title: Process for the manufacture of trans-androsterone and its derivatives
IPC: C07J1/00
Filed: 1936-03-11
Abstract: Dehydro-androsterone is converted into transandrosterone by the action of mild hydrogenating agents such as hydrogen in the presence of platinum black at room temperature or nacent hydrogen at a low temperature.  Careful regulation of the reaction conditions particularly the temperature and pressure enables the hydrogenation of the nuclear double bond to take place without simultaneous reduction of the keto group.  Instead of dehydro-androsterone itself, derivatives may be used, in which the hydroxyl group is replaced by an o-acyl group or an ether group such as o-alkyl or o-aryl.  There is thus obtained corresponding derivatives of trans-androsterone. The dehydro-androsterone used for the process of this invention may be prepared as described in Specification 449,379.  In examples: (1) Dehydroandrosterone is catalytically hydrogenated in glacial acetic acid solution in the presence of platinum black at room temperature. The hydrogenation is interrupted after 1 mol. of hydrogen has been absorbed, and the product poured into water and extracted with ether. The transandrosterone is recrystallized from alcohol; (2) Dehydroandrosterone acetate is hydrogenated under the conditions of example (1) to give trans-androsterone acetate.  Specification 346,130, [Group VI], also is referred to.  The Specification as open to inspection under Sect. 91 comprises also the hydrogenation of halogen derivatives of dehydroandrosterone to the corresponding halogen derivatives of trans-androsterone.  This subject-matter does not appear in the Specification as accepted.
