Title: Improvements in or relating to hydraulic actuating mechanisms
Inventor: NORTHERN DENNIS GEORGE
IPC: E02F9/12
Filed: 1959-06-20
Abstract: 876,273. Hydraulic apparatus. POWER JACKS Ltd. June 21, 1960 [June 20, 1959], No. 21248/59. Class 69 (2). An hydraulic actuating mechanism comprises a pair of double-acting rams 10, 11 coupled by a flexible cable 12 so as to rotate a drum 13, one end of each ram being connected through a control valve 17 to a source 21 of hydraulic pressure, and the other ends of the rams being hydraulically coupled in a closed circuit. When the control valve is moved to connect the hydraulic pressure to the ram 10 to move the piston 10a to the right, the other ram 11 then being connected to a reservoir 20, the movement of the piston displaces fluid through a pipe 14 into the cylinder of the vane 11 to move its piston 11a to the left, thus maintaining the cable 12 taut. The pistons may be formed with one-way valves 10d, 11d which open when their respective pistons are in their extreme right-hand positions to permit make-up fluid to pass into the circuit between the pistons. In an alternative arrangement, fluid may be supplied through a one-way valve in a pipe connected directly to the source and to the pipe 14 between the rams. Springs in the rams may assist in maintaining the tension in the cable and the pistons may have dummy rods on their left-hand sides so as to have opposite faces of equal area. The control valve is provided with a neutral position in which the rams are locked, and a further valve may be incorporated in the pipe 14 to assist the locking action.

If the hair is to be recovered, at least half the alkali metal in the product should be provided by hydroxide; vice-versa if the hair is to be destroyed.  The compounds may be used in a lime system using a slurry containing 6% lime - in this case the hydroxide: P4S10 ratio should be above 12 to 20:1, or the sulphide: P4S10 ratio above 8 to 14:1.  Alternatively a non-lime system may be used, containing 0.5-50% alkali metal or ammonium hydroxide, amines, urea, or ammonia, 0.1-10% CaCl2, Ca(NO3)2, alkali metal carbonates, Zn hydrosulphite, or Ba or Sr chloride, nitrate or sulphate as "sharpening agents", and 0.5-50% alkali metal halides, e.g. NaCl, nitrates, or sulphates as buffering agents; the alkalinity may also be provided by using higher alkali metal hydroxide: P4S10 ratios e.g. 55 to 60:1.  In either case, alkali metal sulphides or sulphydrates, or sulphur may be added as sharpening agents, and the additives may be dry blended with the alkali-metal-P-S compound or added to the solution.  The amount of alkali-metal-P-S compound used may be 0.1-10%, and the unhairing solution preferably has a pH of at least 12, e.g. 12.2-12.8.  (All % are by wt. of the hides).  The hides may first be soaked in water containing up to 2% alkali metal sulphides, tetrasulphides or sulphydrates.  The alkali metal in the P-S compounds may be Na, K, Li, Rb or Cs.ALSO:Alkali metal-phosphorus-sulphur compounds are prepared by reacting a phosphorus sulphide with an aqueous solution or melt of an alkali metal hydroxide or sulphide, using more than 12 moles of hydroxide or 8 moles of sulphide per mole of P sulphide expressed as P4S10.  A mixture of alkali metal hydroxide and sulphide may be used, replacing 2 moles of hydroxide with one of sulphide, or vice versa.  The alkali metal may be Na, K, Li, Rb, or Cs.  The solution of alkali metal compound may be at least 10%, preferably 70% for hydroxide and 60-65% for sulphide; with dilute solutions, water is evaporated during or after reaction to give a solid product.  The P sulphide may be P4S10 to P4S24, and is preferably added to the alkali metal compound to maintain alkalinity.  The products are used for unhairing hides; other active materials e.g. sulphur, and alkali metal sulphydrates, may be mixed with the reactants.
