Title: Improvements in or relating to one-way clutch assemblies particularly for engine starters
IPC: F16D41/00
Filed: 1955-03-17
Abstract: 765,951. Turning-gear. UNITED AIRCRAFT CORPORATION. March 17, 1955 [March 24, 1954], No. 7801/55. Class 7 (5). [Also in Group XXIV] In a engine starter drive having a positive one-way clutch 74, 92 engaged without substantial rotational movement for connecting a ring gear 64, driven by a gas turbine 26 through double reduction gear 42, 44, 48, 64, with a shaft 18 of the engine to be started, the positive clutch comprises a facially ratchettoothed driven member 92, fast with the engine shaft 18, and a complementary driving member 74, connected externally by a left-handed helical spline 72 to the ring gear 64 and internally by a right-handed helical spline 76 to an inner shaft 82 having a forward-drive one-way roller clutch connection 108 with the clutch output member 92. On initial rotation, clockwise from left, clockwise torque, applied to the inner shaft 82 by the ring gear 64 through the double splines 72, 76, is resisted by reaction of the one-way clutch 108 on the stationary engine shaft 18, causing the driving clutch member 74 to screw axially to the right on its internal right-hand spline 76, into toothed engagement with the output clutch member 92 without rotation, which latter follows through the outer left-handed spline 72 on complete engagement. The clutch teeth 78 are sawtoothed with trailing flank angles matched to the angle of the right-hand helix 76. If initial toothed engagement is only partial, engagement is completed by the outer left-hand spline 72, with overrun in the roller clutch 108. If initial engagement is prevented by butting of the top lands of the clutch teeth, the inner shaft 82 is screwed axially to the left against springs 84, 106 with accompanying clockwise rotation of the driving clutch member 74, permitting engagement of the clutch teeth to begin and continue as before. The output member 92 has an oil-slinger ring 98, and the starter construction is generally as also described in Specification 740,845.

Title: Well pumping apparatus
IPC: F04B47/02
Filed: 1968-02-19
Abstract: 1,222,422. Hydraulic reciprocating motors and pumps. HAWK OIL FIELD EQUIPMENT CORP. Feb.19, 1968, No.7916/68. Heading F1A. An oil well pump is actuated by a hydraulic double-acting motor 22, Fig.1 pivoted at 23 on base 15 and acting to oscillate a walking beam 11 connected to the pump by polish rod 18. The motor is supplied by an I.C. engine or electric motor driven pump 32 drawing from a reservoir 28 via a filter 31 and delivering to a reversing control valve 35 via check valve 66 and pressure gauge 67. Reversing valve 35 has a spool 83, Fig.2, which is shifted by beam 11 acting through a block 72 sliding on a rod 71 between adjustable stops 76, 77. Rod 71 is connected by toggle springs 81, 82 and a pivoted weight assembly 91 to 98 to a lever 85 pivoted on a block 86 and connected to spool 83. Buffers 101, 102 limit the swinging movement of lever 85 and prevent rebound. Valve 35 has a neutral position, as shown, in which the connections to the motor cylinder are closed and the supply pump connected to the reservoir. A handle 106 is used to move the valve to its neutral position in which it may be held by a latch 107. Stops 76, 77 are axially adjustable to vary the stroke. During the downstroke of hydraulic motor piston 37, liquid exhausting from beneath the piston passes through a valve 42 which closes if the exhaust pressure rises above a predetermined level, e.g. due to breakage of the sucker rod string. Valve 42, Fig.5, has an adjustably spring-loaded dome 48 with apertures 51 through which exhausting liquid passes. When the exhaust pressure overcomes spring 55, dome 48 is lifted to seat on surface 59, stopping the exhaust flow, a pressure relief valve 61 bleeding off the excess pressure allowing the beam to fall slowly. A pressure-actuated switch 65 acts to cut-off supply pump motor 33. A manual by-pass valve 45<SP>1</SP> is provided in supply line 34 and a pressure relief valve 38 is provided in the connection to the upper end of motor cylinder 22. The cylinder and piston rod pivots 23 and 26 may be positioned at various points along the base 15 and beam 11. In the Fig.9  embodiment, (not shown), the upper and lower ends of the motor cylinder are connected to accumulators. Valves in the connections between the reversing valve and the cylinder ends provide an adjustable throttling of the supply flow through the connections and free flow of exhaust. A manual stop valve is provided in the connection to the lower end of the cylinder for stopping movement of the piston. A pressure responsive valve, Fig.10 (not shown), is provided in the exhaust outlet from the reversing valve to stop the motor when the exhaust pressure rises above a predetermined level, e.g. due to sucker rod breakage, pressure relief valves being provided. The walking beam support constitutes a hydraulic reservoir. The counter balance weights of the walking beam may be suspended from a second horsehead, Fig.9, (not shown), or may be mounted on a beam pivoted to the walking beam support, beneath and parallel to the walking beam, Fig. 7 (not shown).

Patent GB-357121-A (GB)
Title: Manufacture of artificial threads and other products from cellulose compounds
IPC: C08B13/02
Filed: 1930-03-15
Abstract: The process of the parent Specification is modified by using as the agent which is to act on a cellulose compound containing one or more CSS -groups, for example viscose, an inorganic ester of a monohydric alcohol, or a halogen derivative of an ether of a monohydric alcohol, or an ester, other than a halogen ester, of a di- or polyhydric alcohol, or a cyclic ether of a di- or polyhydric alcohol.  Instead of adding these substances as such to the viscose, substances which by reaction give these substances may be added.  As plasticizing agent, sulphuric acid of not less than about 30 per cent or an equivalent of another strong mineral acid may be used.  The mineral acid may be mixed with other mineral acid such as hydrochloric, nitric, or phosphoric acid, or with a salt such as sodium sulphate, sulphite, bisulphite, or nitrite, ammonium sulphate or bisulphate, zinc or magnesium sulphate or with boric acid, glycerine, glucose, alcohol, an aldehyde, a salt of aniline or pyridine, acetic acid, formic acid, lactic acid, or oxalic acid.  Before entering the plasticizing bath, the cellulose compound may be treated with a coagulating agent such as ammonium sulphate, or dilute sulphuric acid containing inorganic salts.  Any coagulating bath known in the viscose art may be used.  In the preparation of the viscose any kind of cellulose material which has been proposed as starting material for the manufacture of viscose or other cellulose esters or ethers may be used.  For example, there may be used cotton, or wood pulp which has been treated with acids or alkalis, or regenerated cellulose may be used.  In an example, diethyl sulphate is added with stirring to viscose and the solution is allowed to age for four days. It is then spun through a platinum nozzle into strong sulphuric acid solution.  The thread is given an extended air path and then wound on a bobbin.  Between the spinning bath and the bobbin the thread is given additional stretch by passing it between glass rods placed angularly to one another.  The spinning may be conducted at a high speed and additional stretching may be dispensed with.  Instead of diethyl sulphate, dimethyl sulphate, ethyl iodide, methyl iodide, benzyl chloride, 1,2-dichlorether, glycerophosphoric acid, glycolsulphuric acid, monoacetin, diacetin, ethylene oxide, glycide, or glycerine carbonic acid ester may be employed.  In the manufacture of the viscose, the cellulose may be directly mixed with the proportion of caustic soda required in the final viscose. In another example, cotton material is impregnated or coated on a padding, backfilling, or spreading machine with a solution of the product of viscose and one of the reagents enumerated above.  To the solution, talc, china clay, mica, or lampblack may be added. The material is then passed, if desired under tension, through a plasticizing liquid, and is then washed and dried.  One of the Provisional Specifications refers also to the addition of halogen derivatives of aldehydes and ketones to viscose.

Filed: 1960-03-10
Abstract: 951,057. Cold-cathode tubes. OHMART CORPORATION. March 10, 1960, No. 8489/60. Drawings to Specification. Heading H1D. [Also in Divisions Gl and G3] In an electric cell comprising two electrochemically dissimilar electrodes in an envelope containing an ionizable gas so that ionizing radiation impinging on the cell produces a current output from the cell when it is connected to an external circuit, the cell is operated at an ion-utilization efficiency of less than 85%, preferably above 10%, in order to reduce the cell noise to a tolerable level. The ion-utilization efficiency is selected by applying an external potential to the cell while the cell is exposed to ionizing radiation and varying the potential until the current output of the cell is a maximum, removing the external potential and observing the maximum current output of the cell, and adjusting one or more cell parameters until the cell output has fallen to a percentage of the maximum corresponding to the desired percentage efficiency. The parameters adjusted are electrode spacing, gas pressure, gas composition and electrode electrochemical dissimilarity. The source is a radioactive substance, an X-ray tube or an ultra-violet lamp.
