Title: Drawbench arm mechanism
IPC: B21C1/32
Filed: 1947-07-10
Abstract: 632,603. Drawing. AETNA-STANDARD ENGINEERING CO. July 10, 1947, No. 18279. Convention date, Jan. 13, 1941. [Class 83 (iv)] A draw bench in which the work is drawn through the die by means of a carriage and is subsequently delivered laterally over a series of discharge arms, includes means for supporting the arms for movement in a substantially horizontal plane and individual fluid-pressureactuated means controlled by the carriage for moving the arms successively from retracted to discharge position. Each arm 14 is carried on a shaft 17 which may be rotated through a pinion 24 on the shaft and a rack 28 which is carried by a member 27 having pistons 29 and 30 at either end. The cylinder 31 for piston 29 is permanently connected to a source of hydraulic pressure fluid through a valve 45 and the cylinder 32 for the larger piston 30 is connected to the source of hydraulic pressure or to exhaust through a valve 46 by means of a control valve. After the drawing and discharge of the work-piece, all cylinders 32 are connected to the hydraulic pressure supply, the members 27 move to the left and the arms 14 are retracted simultaneously, being locked in position by the spring-loaded pawls 66. Before commencing the drawing stroke the control valve is operated to connect all the cylinders 32 to exhaust and the pawls 66 are then tripped in succession by a dog 71 on the carriage framework as the carriage 5 passes the respective arm 14. The hydraulic pressure on each piston 29 then causes the rack 28 and pinion 24 to swing each arm in succession into the discharge position. Each arm and its associated mechanism is supported by a bracket 18 pivotally supported on a rod 20, so that the weight of the drawn tube or bar when resting on the arm 14 moves the arm into contact with the top of the draw-bench. The stroke of the rack-supporting member 27 is cushioned by springs 35 and 36 and by the adjustable exhaust orifices 64 of the valves 45, 46.

Patent GB-671036-A (GB)
Title: The preparation of salts of vitamin b
IPC: A61K31/51
Filed: 1948-07-08
Abstract: The interconversion of salts of Vitamin B1 is effected by the use of ion exchange resins.  The process comprises reacting an aqueous solution containing a salt of Vitamin B1 with an ion exchange resin, said resin containing the same anion as the salt which it is desired to produce, whereby an anion exchange takes place between the said salt of Vitamin B1 and the anion of the synthetic resin to produce the desired salt of Vitamin B1.  The process is applicable to the anion exchange of any salts but is chiefly used to convert thiamin bromide hydrobromide into thiamin chloride hydrochloride, the nitric acid salt of thiamin nitrate or the acetic acid salt of thiamin acetate.  The resins used contain basic groups such as amino groups, and are usually of the phenol formaldehyde type which are characterized by the presence of aminoalkylene aminomethyl substituents on the phenyl nuclei. The resinanion component is prepared by passing a solution containing the desired anion through a bed of the resin in a column and then washing with water.  The reaction between the resin or the anion is best carried out using the corresponding acid.  To prepare resin-exchangers containing anions of weak acids or oxidizing acids such as nitric acid to which the resin is unstable, the resin-chloride is first formed and then reacted with a solution containing a salt of the desired anion.  After the resin-anion component has been prepared the salt of Vitamin B1 which is to be converted is passed through the column preferably in concentration of 20-25 per cent.  In technical operation it is preferred to take a large first cut of Vitamin B1 salt solution as free from starting anions as possible, recover the desired pure salt from this thoughput, wash the column with water, and the effluent which contains a mixture of starting and final salts of Vitamin B1 is used as a starting solution for the next run of the column.  Six examples are given using Amberlite IR-4b resin made as described in example 4 of U.S.A.  Specification 2,402,384, and sold by the Resin Products Chemical Company.

Title: A method of liquefying gaseous chlorine
IPC: C01B7/01
Filed: 1962-05-14
Abstract: 934,394. Liquefaction of chlorine gas. KONINKLIJKE NEDERLANDSCHE ZOUTINDUSTRIE N.V. May 14, 1962 [May 19, 1961], No. 18493/62. Class 8(2). In liquefying chlorine gas by step-wise condensation at 13, 16, Fig. 1, the second condenser 16 is cooled by evaporation of liquid chlorine produced in the process and at a pressure below that prevailing in the liquefying path of the condenser and in quantity such that only a portion of the coolant is vaporized; the mixture of gaseous and liquid chlorine being recycled through a duct 21 to the process e.g., a washing vessel 3 to which feed chlorine gas is admitted through a duct 1. Cold chlorine gas leaving vessel 3 is compressed at 7, 12 and the heat of compression is removed by passage through condenser 13 which is cooled by water or a refrigerant. In a modification the second condenser 30, Fig. 2, is cooled by evaporation of liquid chlorine withdrawn from the first condenser 25 and expanded at a valve 31 and is assisted by liquid chlorine withdrawn through a duct 32 from the cold end of condenser 13 and expanded at a valve 34. A portion of the uncondensed chlorine gas leaving condenser 25 is passed through an injector 38 and serves to withdraw a mixture of gaseous and liquid chlorine from condenser 30 and return it to a washing vessel 37 to which feed chlorine gas is admitted through a duct 23. Specification 353,704 is referred to.

Title: Improvements in means for gripping rods
IPC: B21C1/30
Filed: 1960-05-25
Abstract: 884,925. Rod grippers. ANNEGARN, J. M. J. May 25, 1960 [Aug. 7, 1959], No. 18509/60. Classes 83 (3) and 83 (4). Means for gripping rods to be drawn comprises a split clamp 11 bored to take the rod and enclosed by a resilient sheath 14 of a material such as high density polyethylene. A rigid sleeve 10 which surrounds the sheathed cylinder has end plugs 15 and also forms the pistonrod 7 of a double-acting hydraulic piston and cylinder assembly, which comprises a piston 6, a cylinder 9 and seals 8. A series of the clamp members 11 are arranged inside one piston-rod and two complete assemblies are arranged in tandem (Fig. 1). A system of valves feeds pressure fluid between the sleeve 10 and the sheath 9 and when a predetermined pressure is reached the fluid is passed behind the piston 6 and the rod 4 is drawn through the die 3. Each piston as it nears the end of its working stroke reverses the position of the valve controlling the second cylinder which commences its working stroke, and the first piston then reverses its own control valve and returns to the beginning of its working stroke at high speed.

Title: Improvements in and relating to multiple change-speed gear wheel hubs
IPC: B62M11/14
Filed: 1962-05-14
Abstract: 963,769. Change speed gear; ratchet clutches. FICHTEL & SACHS A.G. May 14, 1962 [May 17, 1961], No. 18521/62. Headings F2C and F2D. A back-pedalling shifted hub gear comprises a planetary gear train having two optional outputs to the hub sleeve, in which shift is produced by relative axial movement of two toothed systems coupled to gear elements rotating at different speeds during backpedalling, one output being uncoupled by movement of the shift tooth system. A sprocket 1 mounted on an input member 2 drives the planet carrier 4 of a planetary train having a sun 7 rigid with the axle 8 and a ring gear 9 formed with a two-depth ratchet tooth system 10, 11 (Fig. 5). The two-depth tooth system co-operates with a single tooth system 12 on an axially slidable ring 13 having pawl 14 and ratchet 15 connection with an entraining ring 16 in lost-motion connection with the hub shell 18. During backward rotation of the input member 2, the ring 13 is driven through a clamp spring ratchet ring 24, engaging a V- groove in the member 2, the speed differing from that of the ring gear 9 so that the teeth 12 ride out of the deeper 10 of two-depth teeth to the shallower 11, moving the ring 13 against a spring 35 and bringing the output pawls 14 into contact with a sloping face of the member 16 to disengage the drive from the ring gear; the drive then being direct from the input member 2, through the planet carrier 9, braking cone 57 and second ratchet clutch 30 to the hub shell. The lost-motion connection between the ring 15 and hub shell provides for backpedalling shift before braking. In modifications, the brake may be replaced by a shift movement limiting stop and the clamp spring ratchet by a jamming roller clutch. The axial movement of the ratchet shift tooth may produce axial dog disengagement instead of movement of one ratchet clutch.
