IPC: F15B7/10
Filed: 1936-06-09
Abstract: 468,989. Hydraulic transmission of power. AUTOMOTIVE PRODUCTS CO., Ltd., and CLENCH, E. C. S. June 9, 1936, No. 16144. [Class 69 (ii)] A double-acting twopipe line remote-control system has a selector valve arranged to connect a common pressure creating device with any one of a plurality of double - acting slave units and to connect the other or others of the units with a reservoir to permit breathing and compensate for temperature changes. The selector valve is constituted by a flat valve body 10 formed with parallel bores 11-15 each containing a piston valve such as 16. This valve has a reduced middle portion 18 and is connected by a pin 21 with a control handle 22. The valve body has through passages 30, 31 with branch pieces 42, 43, at each cylinder to unions 44, 45 which are coupled by pipe lines 46, 47 with a slave unit 48. The bores 44, 45 are connected by cross-channels 49, 50 with the space 35 adjacent the reduced bore 18 when the valve is in the " off " position. The space 35 is connected by pipe line 36 with a make-up tank 37, whilst the bores 30, 31 are coupled by pipe lines 32, 33 with the main pressure creating element 34. The space 35 is connected by a slanting channel 39 to the end chamber 38 so as to provide a balanced pressure on the valve. When a valve control handle 22 is moved, the particular slave unit is coupled up, the remainder being as in Fig. 1, positioned to connect the remainder with the tank 37. Each control handle 22 is provided with a knife-edged extension 52 in line with the joining ends of a series of rods 51 which are under an end spring pressure 57. When any one control handle 22 is moved into the operative position, the knife edge 52 forces its way between adjacent members 51, sliding the remainder into such a position that they block and prevent movement of any other of the control levers. Each control handle is further provided with a contact member 70, which, when in the operative position, completes an indicating circuit to the operator. In a modification, an arrangement is provided whereby in addition the whole of the slave units may be operated simultaneously. When there are two slave units, 81, 82, each has a control valve 83, 84 of the kind already described. In addition, from the main power unit 34 there are two sets of lines 98, 99 and 102, 103, the latter passing to a master control member 85, the pipe lines and the valves providing that when the valve 85 is in the " on " position both slave units are operated, whereas when it is in the " off " position either of the controls 83, 84 can be used to put a respective slave unit into operation. Specifications 443,871 and 468,976 are referred to.

Patent GB-161798-A (GB)
Abstract: 161,798. Crabb, L. S. March 4, 1920. Stencil switches; actuating; handles.-A switch to prevent unauthorized starting of internal-combustion engines is closed as the result of a sequence of movements of the operating handle known only to the owner, and comprises a front disc, having a rearwardly directed eccentric pin, and a coaxial rear disc or discs with a number of angularly-spaced holes, one of which contains a plunger-pin to operate a spring contact-member located behind the discs. Means are provided for angularly and axially displacing and indicating the position of the front disc. In the construction shown, the handle q which is provided with a pointer s is mounted in front of a dial r on the dash-board of a car and serves to rotate the front disc b, mounted together with the switch n, n in a casing a alongside the magneto through a universally-jointed adjustable shaft o. To close the switch the pointer s is first set to the known index figure; this movement carries the eccentric pin f past a number of holes in the first rear disc c mounted coaxially with the disc b until it is brought opposite a hole which contains a long spring-pressed and guided plunger e, whereupon the axial handle knob t is pushed in through one step. This forces the pin f into the hole and the handle q is again rotated to the second code member, moving the disc b, and the first rear disc c with it, until the plunger l is opposite a similar plunger l<1> in one of a series of holes in the second coaxially marked rear disc d. The press knob is again pushed in, thereby pressing the plunger in the first rear disc into the hole containing a plunger in the second rear disc and locking the two discs together, so that, when the handle q is again rotated to the third code member, the two plungers are brought opposite the spring contact arm, and, by further pressing the knob the switch is moved to the closed position. The non-effective holes in the first rear disc may contain spring-pressed plungers of inadequate length to cause operation of the switch but adequate to counterfeit the feel of correct engagement, and those of the second disc may contain springs only, to give the same effect. The knob t is allowed slight angular movement on the operating shaft so that, when the switch is closed, it may be locked by turning a pin t<1> behind a slot in the front plate of the handle q.

Title: Improvements in or relating to artificial filaments, yarns, and like materials
IPC: D01F2/28
Filed: 1935-06-11
Abstract: Artificial filaments, yarns, and like materials of cellulose acetate or other cellulose organic ester or ether are obtained by extruding and setting compositions containing an addition of an oxidized non-drying or semi-drying oil.  Oils having low viscosity and low surface tension are preferred, and the oxidation is preferably carried out so as to avoid polymerization.  High pressures with low temperatures or vice versa may be employed. The oils which may be of animal or vegetable origin may be oxidized at 100-200 DEG  C. in oxygen at a pressure of 45--60 lbs. per square inch above atmospheric pressure.  The oil may be circulated and repeatedly injected through an atomizer.  Whale oil may be present as a catalyst.  Oxidized olive, peanut, cottonseed, castor, coconut, and corn oil are specified.  For cellulose acetate solutions, acetone, or mixtures of acetone and water or alcohol, may be used as solvent.  The solutions may contain pigments, fillers, lakes, dyes, glycerol, or glycol, or the formed articles may be treated with these substances preferably together with swelling agents.  Yarns containing the oxidized oils may be further lubricated by application of a mixture of oxidized oil, water, and glycol or glycol derivative.  In an example, cellulose acetate is dissolved in acetone and to the solution, oxidized olive oil of low viscosity and considerable water tolerance, measured by the ability to absorb a mixture of diethylene glycol and water is added.  The solution is spun into an evaporative atmosphere. The filaments are pliable and yarns made therefrom may readily be knitted.  The Specification as open to inspection under Sect. 91 describes also the application of the process to the manufacture of films, foils and like articles.  This subject-matter does not appear in the Specification as accepted.ALSO:An oxidized animal or vegetable non-drying or semi-drying oil is added to compositions having a basis of cellulose esters or ethers, whereby the lubricating and other qualities of the filaments, yarns formed by extrusion are improved. Oils of low viscosity and low surface tension are preferred, and the oxidation is preferably carried out so as to avoid polymerization. Relatively high pressure with low temperature or vice versa may be employed.  The oils may be oxidized at 100--200 DEG  C. in oxygen at a pressure of 45--60 lbs. per square inch above atmospheric.  The oil may be circulated and repeatedly injected through an atomizer. Whale oil may be present as catalyst.  Oxidized olive, peanut, cottonseed, castor, coconut, and corn oil are specified.  For cellulose acetate solutions, acetone, or mixtures of acetone with alcohol or water, may be used as solvent.  Yarns containing the oxidized oils may be further lubricated by application of a mixture of oxidized oil, water, and glycol, or glycol derivative. In an example, a solution of cellulose acetate in acetone contains an addition of 2--5 per cent of oxidized olive oil.

Title: Improvements in or relating to the measurement of circular dichroism
Inventor: WILKINSON KENNETH REDFERN
IPC: G01N21/19
Filed: 1965-04-21
Abstract: 1,142,501. Photo-electric measurement of circular dichroism. PYE Ltd. April 19, 1966 [April 21, 1965], No. 16894/65. Heading G1A. [Also in Division G2] The circular dichroism of a material is measured by deriving from a common non-polarized beam of radiation two orthogonally plane polarized beams, converting the beams respectively to oppositely circularly polarized beams passing the circularly polarized beams through the material and comparing the intensities of the beams emerging from the material. Light from a monochromator 1 is split by a Wollaston or Rochon prism 5 into orthogonally plane polarized beams 6 and 7. A circular polarizer 8 which may be of the Soleil compensator type converts these beams to left and right circularly polarized beams 10,11 which pass a chopper 12 to fall alternately on a sample 14. Any difference in absorption of the beams 10, 11 shows as a pulsating signal in the output of photo-multiplier 15. The output is synchronously rectified to give a D. C. signal the polarity of which indicates which beam is absorbed most and the magnitude of which indicates the difference in absorption. If circular polarizer 8 is not achromatic it may be coupled to the monochromator 1 for automatic adjustment.
