Title: Rotary hydraulic coupling
IPC: F16H39/16
Filed: 1957-01-28
Abstract: 834,459. Rotary hydraulic couplings. HAAR, F., COHEN, A. L., and COHEN, L. H. S. Jan. 28, 1957, No. 2945/57. Class 69 (2). An hydraulic power transmission mechanism has a housing 21, in which the input and output shafts 75, 106 are rotatably mounted. A core member 46 is fixed in the housing. Inner and outer sleeves 84, 85, rigid with the input shaft 75, are rotatable about the core 46 and have two rows 87, 88 of seven cylindrical openings each, in which act ball pistons 89. The pistons 89 are acted on by cam members 90, 91 of non-circular inner surface which are adjustable relative to one another by means of pinion 94, so that the two rows of pistons 89 are either acting together or in direct opposition, or in any intermediate arrangement, giving an infinitely variable flow of fluid, ranging from nil to the maximum. Sleeves 115, 114 surround the output end of the core 46 and are rigid with the output shaft 106. Two rows of seven pistons 118 each move in radial cylindrical openings 116, 117 in the sleeves 114, 115 and act on a cam 104 with inner surface of substantially square section, causing it to rotate. There are two positions of the cam 104 which give rotation of the output shaft in both directions. Fluid is conveyed from the input to the output end by means of a passageway 65 in the core 46. In the walls of the core 46 at the input end there are radial openings 66 opposite each other, which convey fluid from the inner side of the ingoing pistons to the passageway 65, and two grooves 69 which convey fluid to the outgoing pistons 89. At the output end four passageways 68 and grooves 67 convey fluid to the outgoing pistons and four transfer grooves 70 convey fluid away from the ingoing pistons. Fluid pumped out of the output end via grooves 70 is conveyed back to the input end by passageways 61. A ball 64 which is kept tight over an opening 63 in the core 46 by a spring 59, can be moved to relieve excessive pressure in the passageway 65;

Class 29 [Also in Group XXVII] The Figure shows diagrammatically a hot gas engine A and a refrigerating apparatus B driven by the hot gas engine and operating on the reversed hot gas engine cycle. Means are provided to connect momentarily at a desired moment in the cycle either the working space of the hot gas engine or the working space of the refrigerating apparatus to a common space 8 from which the same working medium is obtained for both the engine and the apparatus. The coupling means (not shown) between the engine and the refrigerating apparatus may be located in the space 8. Also a starting mechanism may be located in the space. A working medium other than air may be used but when air is used as the working medium the space 8 may communicate with the atmosphere by way of a filter. The port for replenishment of working medium of a hot gas engine or refrigerating engine may be arranged in a manner such that replenishment can be effected at any desired moment in the cycle for example at the moment when the pressure of the working medium is at a maximum, a minimum or an intermediate value, the range being sufficiently wide to permit a suitable choice to meet the requirements of economical operation of both the engine and the refrigerating apparatus. A large number of component parts may be used both for the hot gas engine and the refrigerating apparatus.

Abstract: 852,291. Stapling tow. HIRAKO, R. Jan. 29, 1957 [Feb. 20, 1956], No. 3177/57. Class 120(3). A tow 3 is divided by drafting into randomlyarranged fibres of substantially equal length by passing the filaments with their ends arranged at random from slow back feeding rollers 1 to faster front rollers 2, treating the filaments at a point 5, near the back rollers to weaken them and treating the filaments at 6 between this point and the front rollers to restore their strength, whereby as the end of each filament is presented to the front rollers, a tension is applied to the filament causing it to break at the point in its length at which it is then weak. The point 5 may be in front or behind the rollers 1, and the treatment thereat may be with steam, hot air, volatile liquid or high-frequency heating, and the treatment at 6 may consist of drying on a hot-plate.

Abstract: 740,881. Cathode-ray tube circuits. MULLARD RADIO VALVE CO., Ltd. Feb. 8, 1952 [Feb. 9, 1951], No. 3270/51. Class 40 (7). In a cathode-ray tube display system in which the electron beam is focused by a permanent magnet, when the system is switched off the beam persists due to the charge held by the E.H.T. smoothing capacitor and is focused onto a stationary point on the screen thereby dama,ging the phosphor, and according to the present invention this is prevented by providing a storage network in the grid-cathode circuit of the tube so that when the system is switched off the beam is intensified and discharges the E.H.T. capacitor before the beam comes to rest due to the collapse of the sweep potentials. As shown the anode of the video stage is directly coupled to the cathode of the tube 3 and the grid 2 is connected via a stopper resistor 4 to the slider 1 of a brilliance-control potentiometer connected across the H.T. supply of the video stage, the storage network being constituted by resistor 5 and capacitor 6. The same principle is applicable when the control grid of the tube is modulated.

Title: Improvements in the treatment of natural and artificial silk
IPC: D06M11/71
Filed: 1933-02-06
Abstract: Natural silk or fibres of artificial silk consisting of or containing regenerated cellulose or cellulose esters or ethers are weighted by treatment with colloidal solutions of mixed basic chlorides of weighting metals which are prepared by adding to aqueous solutions of the chlorides of weighting metals, one or more carbonates or hydroxides of weighting metals whose chlorides are soluble and phosphates are insoluble followed by the usual treatment with phosphate or other solutions to precipitate the weighting metals.  In a modification, instead of using carbonates or hydroxides of weighting metals, solutions of compounds in which the weighting metal is present in the acid radicle, e.g. sodiumzincate, aluminate, plumbate or stannate may be employed. In an example, zinc carbonate is added to a solution of tin chloride, degummed silk or viscose is treated with the resulting colloidal solution of basic zinc-tin chloride, and the weighting finally effected by treatment with an alkali metal phosphate e.g., disodium phosphate.  The use of hydroxides or carbonates of magnesium, aluminium, tin, lithium, barium, calcium, strontium, cadmium, copper, iron, chromium, uranium lead, bismuth, zirconium, titanium and the rare earth metals is referred to.  The rare earth metals cerium, lanthanum, didymium, thorium, scandium, yttrium, praseodymium, neodymium, samarium, terbium, europium, gadolinium ore ytterbium are mentioned.  For the final weighting step, in place of alkali phosphate, sodium silicate, tungstate and molybdate may be used, and in place of tin chloride, the chlorides of iron, chromium, manganese zirconium and titanium are suitable.
