Heading B7C. A tyre building machine comprises at each end of the building drum a bead core carrier coaxially surrounding ply-turning and stitching mechanism 4 (see Fig. 2, not shown) independently movable axially of the drum by an electric motor coupled with a transmission including at least one screw-and-nut gear. In one embodiment (Fig. 3) the mechanisms 4 are movable axially by racked rods 33 connected via toothed gear (as shown) or lever (not shown) with racks 28 on the piston-rod if a pneumatic cylinder 27. Pressure air is supplied to the cylinder to move the piston-rod to displace mechanisms 4 towards the drum until a shoulder 25 on the rod enters and is locked in a recess in a screw 24 connected to the motor 21 via an internallythreaded worm gear 23, operation of the motor being effective to move the mechanisms 4 towards and away from the drum. In a second embodiment (Fig. 2, not shown) each mechanism 4 is mounted on hollow rods (11) each rigidly connected to a nut (19) keyed for axial movement only and screwed on a threaded rod (15) coupled to the motor (18).

Title: Process for the manufacture of 2-ª -methoxyethylpyridine
Inventor: GREENHALGH NORMAN
IPC: C07D213/30
Filed: 1961-06-05
Abstract: The invention comprises 2-b -methoxyethylpyridine-N-oxide and a process for the preparation of 2-b -methoxyethylpyridine by reduction of the N-oxide.  The reduction is preferably carried out by hydrogen in the presence of a catalyst such as Raney nickel, palladium, platinum or platinum oxide, iron and acetic acid, sodium dithionite, stannous chloride in an aqueous acid medium, phosphorus tribromide or trichloride in the presence of chloroform or ethyl acetate, triethyl-or triphenyl-phosphite, triphenylphosphine or by heating with sulphur.  The N-oxide may be generated in situ and simultaneously or thereafter reduced. The N-oxide is prepared by methylation of 2-b -hydroxyethylpyridine-N-oxide by means of a methylating agent in the presence of an acid binding agent or by methanol in the presence of an acidic or basic catalyst; from methanol and 2-vinyl pyridine-N-oxide or from methanol and a 2,3 - dihydroisoxazolo - (2,3 - a) pyridinium salt in the presence of a catalyst.

Title: Improvement in hydraulic rotary engines
IPC: F04C2/344
Filed: 1928-07-12
Abstract: 293,869. Svartz, J. July 15, 1927, [Convention date]. Fixed-abutment type; packing drums.-In an engine having a concentric rotor and casing and inwardly projecting abutments, the radially sliding vanes 10 are held positively in engagement with the cylindrical portions of the casing surface and are urged resiliently to follow the cam surfaces at the abutments. To this end a cam-shaft 15 is mounted within the rotor and is held from rotation by a yoke 20 and plungers 22 mounted in the rotor carry rollers or balls which ride upon the cam edges 16. The cams are proportioned so that the plungers abut against pins 25, Fig. 3, on the vanes when the vanes are in contact with cylindrical parts of the casing and are separated from those pins at other times, so permitting springs 26 between the plungers and the vanes to press the latter against the curved surfaces of the casing in the neighbourhood of the abutments. The vanes are lightened by radial bores 12 and the contacting surface is reduced by a longitudinal groove 13. The abutments comprise pieces 6 and resilient plates 7 which are ported for the admission and exhaust of the driving fluid.

Abstract: 597,013. Gear-cutting. BRITISH THOMSON-HOUSTON CO., Ltd., COULING, S. A. and LUDBROOK, L. C. Aug. 8, 1945, No. 20349. [Class 83 (iii)] [Also in Groups XXXV and XXXVIII] In a gear-cutting machine with a hob 4 and work-table 2 driven from a shaft 3 through gearing 15 and gearing 16, 1 respectively, selsyn units 6 and 7 are coupled to the hob and table respectively and are arranged to give voltage outputs of the same frequency and to be in phase when no error is present in the relative movements of the tool and table. The occurrence of an error develops a voltage output from the selsyns which, after passing through lines 17 and 18 to a voltage amplifier 8, is indicated on a meter 9 whose recording chart is driven from the shaft of the worm 1. The error voltage also passes to a control unit or power amplifier 10 and thence to a servo-motor 13 which, operating as described in Specification 576,117, [Group XXXVIII], rotates a pinion 11 and differential gear 12 in a direction and through such an angle as to impose the required correction on the rotation of the table 2.

Title: Improvements in forging universal joint yokes
IPC: B21K1/74
Filed: 1962-05-29
Abstract: 995,876. Making universal joints; forging; angular bending; punching; trimmings; working at specified temperatures. M. MACCHINI. May 29, 1962 [May 31, 1961], No. 20588/62. Headings B3A, B3E, B3H, B3V and B3W. A yoke member, Fig. 1, particularly for a universal joint, having a hub 25 with a shaft receiving opening 28 and oppositely disposed ears 26, 27 with aligned bearing receiving openings 46e, 47e normal to the shaft axis, is made by forging. This causes the grain to run along continuous lines 122. A bar 31, Fig. 9, of cylindrical steel stock is heated to 2200-2300‹ F., placed in a first die recess 30a, 30b of a die 29 and upset to shape 33a, 33b by an upper hammer die. The workpiece is then transferred to die recesses 34a, 34b where it is forced to the preliminary shape of two opened yokes interconnected by a bridge 38, with partially pierced holes 40a, 41a, 42a. Further hot-pressing operations are performed successively in die recesses at the " Blocker " and " Finisher " positions. Stop flanges may limit the approach of the upper die. The workpiece, whilst still hot, is transferred to a trimming and punching die 56, Fig. 11, where its periphery is trimmed by a cutting edge 84, Fig. 10, or an upper die 72; simultaneously, the holes 45c, 46c, 47c are punched through to cylindrical shape by punches 77-82 and the bridge 60 is sheared off. A hold-down block 85 slidable in the upper die 72 strips the workpieees therefrom when the upper die is raised. The workpieces, then at a temperature of 1500-1600‹ F., are transferred to a bending machine, Fig. 17, comprising a vertical slide 86 carrying a pair of wing elements 89, 90, pivoted thereto at 91, 92 and co-operating with stationary and adjustable cam surfaces 95a, 96a. The ears 26, 27 of the workpiece seat in recesses in the wings and downward pressure is applied to the workpiece hub 25 by a vertical presser 103 which may be operated hydraulically. Simultaneously the slide is moved downwardly by a screw 116 carried by the presser. This causes the wings to ride over their cam surfaces 95a, 96a and pivot inwardly whereby the ears are bent into positions 26a, 27a, parallel with each other. Spring-loaded dogs 105, 106 act as strippers to hold the workpiece in its lower position during retraction of the presser 103 and slide 86 which has a lostmotion connection 117, 118, 119, 120 with the presser.
