Title: Improvements in or relating to Tube-Drawing Machines
IPC: B21C1/24
Filed: 1968-07-15
Abstract: 1,180,535. Drawing. MANNESMANN-MEER A.G. 15 July, 1968 [2 Oct., 1967], No. 33639/68. Heading B3P. [Also in Division F2] In a tube-drawing machine having a plurality of plug rods 1 mounted on a rotatable drum 2, the axial position of each rod 1 carrying a tube to be drawn is finely adjustable when in the operative position by a screw-threaded means 8 rotatable by a motor 7, the two being coupled when the rod 1 is extended towards the die 17 by the engagement of an externally-toothed hub 13 and an internally-splined collar 12 respectively rotatable with the screw-threaded means 8 and the motor 7. A tube to be drawn is passed over a plug rod 1 in the upper loading position and the drum 2 rotated through 180 degrees to the lower operative position whereby a lug 5 engages in a groove in a carriage 6. The plug rod 1 is moved to the operative position towards the die 17 by reciprocating the carriage 6 by means of an hydraulic piston and cylinder 4. The external teeth of the hub 13 are caused to be engaged between the teeth of the collar 12 so that the motor 7 may rotate the hub 13, which rotates spur gears 9 controlling an adjusting nut 8 which axially adjusts the plug rod 1. If the hub and collar teeth abut when the rod 1 is moved to the operative position, a spring 14 is compressed and causes the teeth of the hub 13 and collar 12 to engage between each other as soon as the motor 7 is started. The coupling is automatically disengaged when the plug rod 1 is retracted.

Title: Improvements in and relating to the preparation of vitamin b
IPC: C07H23/00
Filed: 1956-11-07
Abstract: Vitamin B12 active substances are obtained in a process which comprises adsorbing an aqueous acidic solution containing Vitamin B12 active substances and impurities on a cationexchange resin, said resin containing carboxyl groups bonded to polymeric aromatic radicals, and having an average wet particle size of less than 60 mesh, washing the Vitamin B12 active substances adsorbed on said resin first with an aqueous acidic solution, then with a watermiscible oxygen-containing organic solvent and subsequently again with an aqueous acid solution, and thereafter eluting the Vitamin B12 active substances from the washed adsorbate.  As Vitamin B12 substances there may be used cyanocobalamin, hydroxycobalamin, Vitamin B12C, Vitamin B12D, and concentrates of Vitamin B12 substances derived from liver and fermentation products.  The process is suitable for batch or column operation. The aqueous acidic solution employed in the first and third washings preferably has a pH below 2.5 which is adjusted by means of a strong mineral acid such as formic or trichloracetic acids. For the second wash a water-miscible, oxygen-containing organic solvent having less than 5 carbon atoms is employed, e.g. ethanol, methanol, propanol, isopropanol, butanol, t-butyl alcohol and acetone.  Alternatively the Vitamin B12 active substances are eluted from the cationexchange resin with an aqueous solution of a water-miscible oxygen-containing organic solvent, e.g. dioxane containing a non-oxidizing mineral acid at a concentration of between 0.05 and 0.15 N.  Prior to treatment the Vitamin-B12 substances may be first converted to cyanocobalamin by treatment with alkali metal cyanide.  Examples describe the preparation of Vitamin B12 substances from Milorganite, liver extract, and other Vitamin B12 compositions.

Title: Improvements in or relating to steering gear for ships and like craft
IPC: G05D1/02
Filed: 1936-12-11
Abstract: 474,118. Automatic control systems. GENERAL ELECTRIC CO., Ltd. Dec. 11, 1936, No. 34079. Convention date, Dec. 24, 1935. [Class 38 (iv)] [Also in Groups XXXIII and XXXVIII] Steering-gear for ships including a photoelectrically controlled motor which drives a course indicator and also a course recorder wherein there is also provided a clutch mechanism whereby the indicator motor may be associated with hand steering gear or with mechanism responding to the movements of the motor for automatic steering. There is provided a photo-electric installation carrying the card 8 of a compass which on movements of the ship in azimuth or on deliberate movement of the arm 11 results in one of the contacts 16-17 becoming established and the corresponding relay circuits 15-19 being energized and thus producing motion of a motor 20. The motor 20 drives a shaft 24 which actuates the indicator 28 and also by further gears 25 and shaft 26 actuates the controller 11. With hand steering the clutch 7 is moved to disconnect the shaft 6 from the shaft of the motor and when the hand steering wheel is moved and the ship moves off its course the motor 20 under the influence of the member 11 produces corresponding movement of an indicator 28 and may also operate through electric connections a second indicator 31 and the course recorder 32. A motor 33 has a clutch connection 34 with the shaft 35 but when a reversing switch 36 is engaged to set the motor in motion the magnetic clutch is disengaged and the chain connection 21 to the motor 20 is freed. The motor 33 then acts to turn the carrier and establishes a new course and the indicators are re-set. Alternatively the hand wheel 40 may be engaged with the shaft 24 and used to establish a new course and in these cases the hand steering wheel is used to bring the ship round. For automatic steering the clutch 7 is engaged and the motor 20 drives the steering shaft 6 until the deviation of the ship is corrected and the control 11 is back to neutral. When a separate steering motor 42 is used, the chain connection 50 is engaged with the shaft 6 by a coupling 41 and a second chain connection 43 drives a follow-up gear therefor. This follow-up mechanism includes a circular track 44 with contacts 51 co-operating with a roller contact 45 driven by a repeater motor 46 driven from the circuit 30 which is controlled by the photo-electric cell installation 11. The track 44 may be turned by a hand wheel 52 to establish a new course. The dial 27 may have compass indications and it and the indicator are relatively adjustable for correcting initial errors.
