Title: Improvements in and relating to the production of hollow metal bodies
IPC: B21C45/00
Filed: 1930-09-15
Abstract: 362,539. Making hollow bars. POLLAK, J. E., 20, Holborn, London. Sept. 15, 1930, No. 27553. [Class 83 (iv).] Cores.-In making hollow metal bars or pipes, such as borers, stay-bolts, hollow shafts, by forging or rolling a hollow blank on a metal core and then removing the core, a steel alloy core is used having no transition point or a transition point below that of the steel of the blank and the composite bar after reduction is cooled from a temperature above the transition point of the bar to a temperature below that point, but above the transition point of the core, if any, and the core is withdrawn when the temperature falls between these limits. The expansion of the bar during transformation from gamma to alpha steel separates the blank from the core which can thus be easily removed without applying tension. A suitable core is formed of a steel alloy containing nickel, chromium, manganese or silicon, or a combination thereof. The temperature required for finishing the rolling may be above the transformation point of the bar, or the composite blank may be subsequently heated to that temperature, preferably electrically. The cooling from this temperature may be effected in water, oil or air. Before the blank is heated for the reduction process, the ends of the core and blank may be partly or entirely connected by welding &c. so as to vary the supply of air in order to obtain a film of oxide between the surfaces during heating, to act as a lubricant and facilitate subsequent removal of the core. The parts for this purpose are previously cleaned by pickling.

Abstract: 1463126 Silicone resins GENERAL ELECTRIC CO 21 June 1974 [20 Sept 1973] 27756/74 Heading C3T A process for producing a silicone resin comprises (a) contacting an organotrihalosilane and/ or a diorganodihalosilane where the or each organo group is a monovalent hydrocarbon or halohydrocarbon radical or a cyanoalkyl radical with water and an alcohol of the formula R<SP>1</SP>OH where R<SP>1</SP> is a C 1 -C 3  alkyl radical, generally at room temperature, such that there is formed an alkoxylated organohalosiloxane containing 5-50% wt. alkoxy groups; (b) adding an alcohol of the formula R<SP>1</SP>OH and removing acid from the alkoxylated organohalosiloxane, generally by distillation under vacuum, to an acid concentration in the hydrolysis medium of 500-4000 p.p.m.; (c) adjusting the acidity of the alkoxylated organohalosiloxane to an acid concentration in the hydrolysis medium of 1- 300 p.p.m., generally by adding a base such as KOH or NaOH or by repeating step (b) or both, (d) adding water and optionally an alcohol of the formula R<SP>1</SP>OH to hydrolyse the alkoxylated organosiloxane, and (e) adjusting the resulting hydrolysate to the desired solids content. The alkoxylated organohalosilane from step (a) is generally distilled at the reflux temperature to decrease the hydrogen halide content to at least 1% wt. before step (b) is carried out. The silicone resin produced generally has the following properties: an R/Si ratio of 1 : 1 to 1À9 : 1; a ratio of trito difunctional units of 1À0 : 0 to 1 : 6; an OH content of 1À5-8% wt. and an alkoxy content of 0À2-4À0% wt. Step (e) may be carried out by heating the hydrolysate to 60-100‹ C. to remove all water and as much alcohol as necessary; or a solvent selected from toluene, xylene, benzene, cyclohexane, octane, heptane, butyl acetate, mineral spirits and naphtha solvents may be added to the hydrolysate and water and the alcohol azeotroped out at 80-130‹ C. to obtain a solution of the resin in one of the above solvents. The OH content of the resin may be reduced to 0À1-1À5% wt. by adjusting the hydrolysate to a solids concentration of 85- 90% wt. by distillation, adding a catalyst selected from manganese octoate, cobalt octoate, iron octoate or zinc octoate and bodying by heating to reflux at 150-170‹ C. for 2-20 hours. In the examples resins are produced as above using a mixture of methyltrichlorosilane and phenyltrichlorosilane alone and together with dimethyldichlorosilane and diphenyldichlorosilane as organohalosilane and methanol as alcohol.

Abstract: 905,756. Coin-freed apparatus. GENOSSENSCHAFT HAMMER. Aug. 12, 1960 [Aug. 15, 1959], No. 28081/60. Class 27. A coin-operated machine of the kind comprising separate conduits 12, Fig. 2, for the reception of coins of different values and abutments 19, Fig. 7, arranged in the respective conduits so that inserted coins are located in the path of locking pawls 22 which, upon actuation of the machine, are displaced and moved by the coins out of locking position is provided on its wall 4 with means for receiving an interchangeable front plate 1 which is provided with one or more coin slots 2 for registration with the particular conduit or conduits corresponding to the price of the transaction for which the machine is to be set and with means adapted upon installation of the plate on the wall 4 to raise out of locking position the pawls 22 of the conduits for which there is no coin slot in the plate. Selection of the appropriate front plate is made from a number of plates having the coin slots 2 in different positions for co-operation with different conduits and therefore relating to different transactions. The machine is described as having three conduits 12 serving respectively for the insertion of 10, 20 and 50 franc coins depending upon which front plate 1 is in position. This front plate is retained on the wall 4 by a latch 10, and, as shown in Fig. 2, is provided with one or more suitably placed pins 3 for coaction with cables 14, 15 when fitted on the wall. A coin inserted in a conduit is stopped by an abutment 19 in the form of a pin and, upon operation of the pusher 21 of the machine against the action of a spring 20, so deflects the corresponding pawl 22 (all of which are pivoted on a shaft 63 on the pusher) that the pusher is released to carry out its full operating cycle. The pawls 22 of the conduits for which there is no entry slot in the plate 1 are, as described above, released upon installation of the plate by the action of the pins 3 through the cables 14, 15. During its operative travel, the pusher 21 acts through linkage 36, 38 to withdraw the abutments 19 from the conduits and so allow the coins to drop into a cash box. Inserted coins may be recovered before actuating the machine by depressing a push-button 43 to cause linkage to retract the abutments and operate a flap to divert the coins to a return shoot. In case the machine should be required to carry out transactions involving the insertion of two coins of equal value in the same conduit, the conduit is fitted with two superposed abutments 19 separated by a distance equal to the diameter of a coin, and for such transactions the front plate 1 is provided with a pin 3, coacting with a cable 14<SP>1</SP>, 15<SP>1</SP> to withdraw the upper abutment so that the first coin inserted drops down on to the lower abutment and itself serves as a release abutment for the second coin. The pins 3 on the plates may control the pawls 22 through electromagnets or they may serve as members controlling photo-electric cells for operating the pawls.
