Title: Improvements in or relating to a manipulator
IPC: B21J13/10
Filed: 1950-06-08
Abstract: 671,869. Load-handling trucks. BROSIUS, CO., Inc., E. E. June 8, 1950. [Dec. 3, 1949] No. 14315/50. Class 78 (iii). [Also in Groups XII and XXII] A manipulator for handling forgings or for charging work into or withdrawing it from furnaces or other treating chambers, comprises a frame and a peel, and is characterised in that the peel is mounted so that it may be moved transversely across the frame. The main body of the manipulator has two front wheels 2 mounted on a shaft 4, which is preferably fixed, and a single driven rear wheel 3 mounted in a bracket 6 carried bv a rotatable vertical shaft. Behind the shaft 4, another shaft 14 also extends between the frame side members 10. On each of these shafts is a longitudinally movable sleeve 17 extending between bushings 15 and carrying members 18 which form the main members of a peel carrier which may thus slide along the shafts 4 and 14 transversely of the manipulator under the control of a pneumatically operated piston. Bellows 47 protect the ends of the shafts from dirt and grit. Within its carrier the peel may be mounted in known manner so as to be capable of rotation by a hydraulic motor 33 through-a coupler and gearing 35 and of movement in a vertical plane under the control of cylinders 27 and 30. The jaws are opened and closed in known manner by a piston in a cylinder 37 carried by the peel.

Title: A process for imparting improved tear resistance and abrasion resistance to cellulosic textile materials
Inventor: CHIPALKATTI VASANT BHIMRAO
IPC: D06M13/11
Filed: 1965-04-06
Abstract: Yarns and fabrics containing natural or artificial cellulose fibres alone or in admixture with non-cellulosic fibres are treated with an ester of a dihalo-propanol having an acyl group with a chain length of not less than 8 carbon atoms in the presence of aqueous alkali/alkaline agent, e.g. potassium or sodium hydroxide and sodium aluminate or zincate, until 0.8-3.63% by weight of the ester is fixed on the fibres, so that they are simultaneously given improved abrasion resistance and tear resistance.  The material treated, e.g. cotton fabric, may be dipped into a solution or aqueous emulsion of the ester, e.g. lauroyl ester of 1:3-dichloro-propanol-2, stearoyl ester of 1:3-dibromo-propanol-2, myristoyl ester of 1:2-dichloro-propanol-3, palmitoyl ester of 1-bromo-3-chloro-propanol-2 or stearoyl ester of 1:3-dichloro-propanol-2 or a mixture thereof and then treated with the aqueous alkali/alkaline agent which may be used in a concentration of 10 - 40% by weight with or without removal of the organic solvent/water, wrapped in an inert and substantially vapour impermeable material, e.g. a polyethylene sheet, and kept with or without pressure for a period of up to 24 hours to complete the reaction.

Title: Improvements in feed devices for clutches for hydraulically operated change speed gears
IPC: F16D25/10
Filed: 1938-05-16
Abstract: 496,466. Variable - speed gearing. KEGRESSE, A. May 16, 1938, No. 14593. Convention date, April 16. [Class 80 (ii)] A centrifugally-actuated control valve for a group of hydraulically operated clutches of a change-speed gear of the kind described in Specifications 466,543, 482,632, and 489,317, comprises a double-acting valve member 5, 6 radially arranged on the rotating clutch housing 2, the inner end of which controls the supply of pressure fluid through passages 49, 50 from a pump 44 and the outer end the exhaust of the pressure fluid through an outlet 71. At a certain minimum engine speed the valve 5, 6 moves out under the action of centrifugal force against a spring 11 to pass the pressure fluid to a chamber 53 behind the diaphragm 16 of the first speed clutch 17, 18 and to close the exhaust outlet 71. The first-speed clutch is thereby engaged. The passage of the pressure fluid from the pressure chamber of the firstspeed clutch is controlled by valves 12 of different spring-loadings for the second and third speed clutches 17, 23 and 33, 32 respectively, which valves operate as the engine speed and pressure of the fluid rises to bring in second and third speeds successively. The driven gears 36, 26 and 21 are in free-wheel connection with the driven shaft 22 so that on the higher speeds the lower speed gears over-run. As the engine speed falls the third and second speed clutches are successively released by the fall in pressure of the fluid, the valves 12 opening to exhaust, and finally the valve 5, 6 is moved inwardly to open the exhaust outlet 71 to release the first-speed clutch. If the vehicle is stopped suddenly by application of the brakes the valve 5, 6 may open to exhaust first to release all the clutches simultaneously.

Abstract: 272,216. Weichel, O. June 2, 1926, [Convention date]. Cupola furnaces.-In a cupola furnace having two or more rings of tuyere nozzles each with a damper for controlling the passage of the blast, the dampers for nozzles located on or near the same vertical line are mounted on a common operating-spindle. As shown in Fig. 2 the spindle c is journaled vertically in the upper and lower walls of the blast casing b, and carries two doors d', d<2> for controlling the blast supply through the tuyeres a', a<2>. The upper door is fixed to the spindle, while the lower one is mounted on a sleeve c<1>, which can be clamped in any desired position on the spindle by a set-screw c<2>. When two tuyeres are not on the same vertical line the spindle is positioned between them, and the doors are so mounted that when one tuyere is open the other is closed, and vice versa. In all cases the spindle is so positioned that it does not obstruct the observation opening f. In a modification the controlling-device takes the form of a part cylindrical valve d<1>, Fig. 4, and in this case the spindle c may be mounted either in the casing b as in Fig. 2, or in a vertical pipe b<2>, from which branches b<3> lead to the tuyeres. At the lower end of each spindle is a hand wheel e, and at the upper end is a pulley e<1> for a rope drive, which may be common to all the controlling-devices for the furnace. The drive may be hand or motor actuated, and the spindles will be rotated or oscillated according to the type of valve used. By proper setting of the valves upon their spindles the blast may be caused to travel round the furnace, the various tuyeres being brought into operation in succession.

Title: New hydroquinone compounds and process for their manufacture
IPC: C07D203/14
Filed: 1956-05-14
Abstract: The invention comprises compounds of the formula <FORM:0825760/IV (b)/1> wherein R1 and R2 are alkoxy or alkylmercapto groups, the alkyl groups of which contain 1-4 carbon atoms, and salts of these compounds.  The compounds are made by treating the corresponding quinone with a reducing agent, for example sodium dithionite in alkaline solution or hydrogen in the presence of a nickel catalyst. The reduction is suitably carried out in the absence of oxygen, for example in an atmosphere of hydrogen or nitrogen.  If desired, the starting materials may be formed in the course of the reaction.  For example, quinones wherein R1 and R2 are exchangeable substituents such as halogen atoms, can be treated with an excess of a lower alkyl mercaptan, preferably in the presence of an alkali-metal.  In examples: (1) 3:6 - diethoxy - 2:5 - bis - ethyleneimino - p - benzoquinone is hydrogenated in the presence of Raney nickel to give 3:6-diethoxy-2:5-bis-ethyleneimino hydroquinone; (2) 3:6-dichloro-2:5 - bis - ethyleneimino - p - benzoquinone is treated with methyl mercaptan in the presence of metallic sodium and the reaction mixture is treated with sodium dithioxide in alkaline solution to complete reduction to 3:6-bis-methyl-mercapto - 2:5 - bis - ethyleneimino - hydroquinone; (3) 3:6 - dichloro - 2:5 - bis - ethyleneimino - p - benzoquinone is treated with an excess of methyl mercaptan in the presence of sodium to give the product of (2); (4) 3:6-dichloro-2:5-bis-ethyleneimino-p-benzoquinone is treated with an excess of ethyl mercaptan in the presence of sodium to give 3:6-bis-ethylmercapto - 2:5 - bis - ethyleneimino - hydroquinone; (5) 3:6-diethoxy-2:5-bis-ethyleneimino-p-benzoquinone is reduced with sodium dithionite to 3:6-diethoxy-2:5-bis-ethyleneimino-hydroquinone; and (6) the product of (1) is converted into its disodium salt.
