IPC: C21B7/18
Filed: 1917-12-08
Abstract: 117,024. Wurth, P. Dec. 8, 1917. Overhead travellers and transporters.-In a charging-apparatus for furnaces of the kind in which a skip e is first lifted to the level of the furnace top by winding mechanism mounted on a car a and is then travelled horizontally until over the furnace mouth, the weight of the skip during its vertical movement is balanced by coupling the winding mechanism to a counterweight. As shown diagrammatically in Fig. 3 in connexion with a pair of blast furnaces, the apparatus comprises two cars a, b, the winding mechanism of which can be coupled by a clutch so that the weight of an ascending skip e for one furnace is balanced by that of the descending skip f of the other. The rails for the cars a, b, may either be in line, or at an angle to one another. When used for a single furnace the winding mechanism on the car is coupled to the winding drum of a counterweight.

Patent GB-735118-A (GB)
Title: Improvements in and relating to the production of acetylenic hydroxy compounds
Inventor: WHITFIELD GORDON HOWARD
Filed: 1952-07-21
Abstract: Acetylenic hydroxy compounds are obtained by reacting acetylene with a ketone which contains the grouping -CH2.CO.CH2- and is liquid under reaction conditions, in the presence of a quaternary ammonium hydroxide anion exchange resin at a temperature in the range of 40 DEG  to 120 DEG  C. and at an elevated acetylene pressure within the range 1 atmosphere to 30 atmospheres gauge.  Suitable exchange resins are those in which each nitrogen atom is attached to three alkyl groups and to a methylene group, the methylene group being attached to a monocyclic aromatic group which is a constituent part of a cross-linked organic polymer.  A particularly suitable exchange resin is one in which the nitrogen atom is attached to three methyl groups and a methylene group, the methylene group being attached to the phenyl group of a poly-styrene resin. Commercially available exchange resins are "Amberlite Ira 400 (OH)" and "Amberlite Ira 410 (OH)" (Registered Trade Marks). The acetylene employed may be diluted with an inert gas, e.g. nitrogen.  Examples disclose the preparation of (1) 2-methylbut-3-yne-2-ol and 2,5 - dimethylhex - 3 - yne - 2,5 - diol from acetone; (2) 3-methylpent-4-yne-3-ol from methyl ethyl ketone; and (3) 1-ethynyl cyclohexanol and di-(1-hydroxy cyclohexyl) acetylene from cyclohexanone; the 2-methylbut-3-yne-2-ol obtained in (1) may be recycled with unreacted acetone to the reaction vessel, to give an increased yield of 2,5-dimethylhex-3-yne-2,5-diol.

In the embodiment shown, unwinding of the cable drives combined pumps and motors 2, 3 via a shaft 1 to transfer hydraulic fluid from a tank 4 to the accumulator 10 via non-return valves 9. To rewind the cable, a valve 11 is opened to cause the pressurized fluid in the accumulator 10 to be forced into lines 6, 7, 12 so that 2 and 3 now act as motors to turn shaft 1 and rewind the cable. A restriction 13 in line 12 gives rise to a pressure drop therealong thus facilitating the inflow of fluid from tank 4 via a line 14 and a non-return valve 15. The hydraulic system may be replaced by a pneumatic system (air compressors and pneumatic motors, no tank 4). The pumps may be separate from the motors, and may be of greater capacity; and there may be more pumps than motors.
