Title: Improvements in or relating to mechanical forging processes and apparatus therefor
IPC: B21J9/08
Filed: 1934-11-01
Abstract: 448,426. Forging machines. BENEDETTO, G., and OMES, Ltd., Beverley Works, Willow Avenue, Barnes, London. Nov. 1, 1934, No. 31395. [Class 83 (iv)] In electrically upsetting tubes the work is supported between electrodes so that a part is heated, end pressure is applied thereto, the increase of thickness is directed radially by a part of the electrodes surrounding or entering within the tube, and the unsupported span of metal between the electrodes at the start of the operation is not substantially greater than four times the wall thickness of the tube. As shown in Figs. 1 and 5, a hydraulic cylinder 16, has a ram 17, operating .on a cross head 18 moving on slide bars 14, 15. A handwheel 25, ratchet and screws 19, 20 provide adjustable stops for forward movement of the cross head. A member 26 bolted between the slide bars, carries a vice comprising two jaws 27, 28 radially adjustable and two jaws 29, 30 mounted on the rams of hydraulic cylinders 33, 34 disposed radially to the axis of the tube 35. The jaws are preferably water cooled, are replaceable, and are made of bronze or other good conducting metal. An anvil 47 is adjustable longitudinally and water cooled. A head 60 on an extension 59 from the ram abuts on the work, a cross piece 58 supporting the extension. Cross members 61, 62 carry jaws 63, 64 for supporting the work, rotation of a cam forcing spring pressed jaws against the work. With very long work pieces, the extension 59 is dispensed with and with short work pieces a longer extension is required. A longitudinally adjustable stop 81 engages the cross head 18 to limit the retraction of the ram under the action of cords 83, 84 attached to a counterweight 87. In operation, with the work in position, a handle 95 is moved to close the vice jaws 29, 30 and apply pressure to the cylinder 19. Oil pressure actuates a cylinder in a switch, box closes a circuit of supply mains and current flows from the vice jaws through work to the anvil. As soon as forging heat is reached the work is pushed through the vice jaws towards the anvil until a bracket 88 engages a knockout stop 96. Thereby a latch is retracted against spring action and the handle 95 will spring up and release hydraulic pressure. Thereby the vice jaws are freed from the work, the ram is drawn back by its counterweight and electric current is cut off. In a modification the vice described in Specification 368,325 is employed. Specification 422,721, [Group XL], also is referred to.

Abstract: 1354164 Steroido-oxazolines GRUPPO LEPETIT SpA 7 July 1971 [9 July 1970] 31898/71 Heading C2U Novel steroids of the formula wherein X is H or halogen; Y is O or H(OH); or X and Y together represent a further bond between the 9- and 11-carbon atoms; R is H or acyl; and R<SP>1</SP> is C 1-5  alkyl, are prepared by heating a steroid of the formula (wherein Ac is the acyl radical of a C 2-6  alkanoic acid) with a weak base in the presence of a polar aprotic solvent to form a steroid of the formula hydrogenating this to remove the #<SP>15</SP>-double bond, cyclizing the α-epimer or the α- and #- epimeric mixture of the thus-obtained 16-acylaminopregnane and then converting the [16α, 17α-d]-fused oxazoline-steroid produced to the required product by known methods of introducing #<SP>1</SP>- and #<SP>4</SP>-double bonds, a 3-keto group and the required moieties X, Y and R. An 11- keto group may be reduced to an 11#-hydroxy group, the 20-keto group being protected and subsequently released, and the 11#-ol formed may be dehydrated to a 9(11)-ene. If the 20- keto group is protected by semicarbazone formation, hydrolysis by treatment with hydrochloric acid results not only in release of the 20- keto group but also in dehydration to the 9(11)- ene. Also, in reduction to the 11#-ol if a strongly basic aqueous solution of sodium borohydride is used hydrolysis of the 3#-acyloxy group also takes place. A 21-acetoxy group may be introduced by 21-iodination followed by exchange between the iodine atom and an acetate ion. The resulting product may be oxidized to a 3- ketone into which #<SP>1</SP>- and #<SP>4</SP>-double bonds may be introduced by bromination and dehydrobromination. A #<SP>1,4,9(11)</SP>-triene may be converted into a 9α-halo-11#-ol by treatment with NBA to give a 9α-bromo-11#-ol and, when required, dehydrohalogenation of this to give a 9#, 11#-epoxide and reaction of this with HF to give a 9α-fluoro-11#-ol. 16# - chloroamino - 3#,17α - di-alkanoyloxy-5α- pregnane-11,20-diones are prepared by reducing 3#,17α - di - alkanoyloxy - 16# - azido - 5α- pregnane-11,20-diones (prepared by acylation of the diols) to the corresponding 16#-amino compounds and then chlorinating these. 5α-pregnane 16#-azido-3#,17α-diol-11,20-dione is prepared by reacting 5α - pregnane - 16α,17α - epoxy - 3# - ol- 11,20-dione (in turn prepared by epoxidation of the corresponding 16-ene) with sodium azide.

A plain fabric with a ribbed edge is knitted on a straight bar machine and to change from rib to plain knitting all the loops are arranged on the frame needles whereafter transfer points perform a number of successive narrowing operations to form double stitches on spaced needles. Thus the plain fabric is no wider than the rib fabric. The point bars 22, 22a transfer loops from a group of needles one space inwards to form double stitches, then are shogged several needle spaces so that they may engage a different number of needles at the following narrowing operation. The operation is repeated until the required number of double stitches has been formed. The bars may commence the cycle at each end (or the centre) of the bed and after, each transfer are shogged inwards (or outwards) and successively take an increasing (or decreasing) number of loops. The main cam shaft is provided with a cam 54, engaged by an axially movable follower 51, operative to rack the transfer bars single or multiple spacings during the doubling operations.

Void [Abridged as open to inspection under Sect. 91 of the Acts, May 8, 1935]. [Class 99 (ii)] Pressing mechanism for the tubular bodies of paper &c. bottles &c. is constructed in such a way that the pressing operation is not commenced until the pressing tool 3 has completed its axial movement into the mould 1. When the ram 2, carrying the tool 3, has almost completed its axial movement, a stop 11 bears against the mould 1 to prevent further movement of the rod 7 by reason of the connection 8. During the short remaining stroke of the ram the rubber cone 4 is compressed between the nuts 5, 6 to press the paper &c. body against the mould. A further rubber 12 may be fitted which effects pressure in widening the neck of the bottle &c. by contact with a controlled tool 15. If desired, the stop 11 may be dispensed with, the tool 15, by contact with the rod 7, effecting, simultaneously, the outward movement of both rubbers 4, 12.
