Abstract: 867,809. Valves; hydraulic apparatus. CARLS, W. Nov. 6, 1957 [Nov. 6, 1956], No. 34648/57. Classes 69 (2) and 135. A valve for controlling a fluid motor comprises a housing having a bore 12, a port 14 intersecting the bore at two spaced areas 18, 20 and another port 16 intersecting the bore between the spaced areas, a first sleeve 50 sealing with the body and having a sliding fit with a valve spool 34 sliding in the bore, the sleeve connecting the ports in one position of the valve spool, e.g. via openings 120, 58, a second sleeve 70 slidable on the spool relative to the housing and being biased e.g. by spring 72 to permit unidirectional flow from one of the ports to the other regardless of the position of the spool valve. The valve may be incorporated in one or both lines leading to a piston and cylinder motor, the spool being actuated through lever 28 by a cam on the piston rod. As the piston moves from one end to the other to its cylinder, fluid is exhausted from the cylinder from 16 to 14 and as the piston rod cam depresses the spool valve the flow is gradually restricted whereby the speed of the piston is reduced. To move the piston in the opposite direction fluid flows from 14 to 16 via the check valve 70. An adjustable by-pass is provided at 80, 82. Pressure below the spool valve is relieved through a spool passage 122, 124.

Patent GB-383764-A (GB)
Title: Manufacture of condensation products
IPC: C08F8/28
Filed: 1931-12-15
Abstract: Condensation products are manufactured by causing a cyclic ketone (i.e. a ketone having a C = O group as a member of a hydroaromatic ring) to react with a polyvinyl alcohol (obtainable by saponifying polyvinyl acetate) in the presence of a condensation catalyst of acid reaction.  Instead of a polyvinyl alcohol a polyvinyl ester may be employed provided that the conditions of working are such that the corresponding polyvinyl alcohols are intermediately formed.  As catalysts may be employed acids, e.g. sulphuric acid, hydrochloric acid, phosphoric acid, monochloracetic acid, dichloracetic acid, borofluoroacetic acid (obtained as a solution in acetic acid by introducing boron trifluoride into glacial acetic acid), oxalic acid, formic acid, lactic acid or an aromatic sulphonic acid, also zinc chloride or aluminium chloride.  The acids or acid reacting substances are preferably diluted to a hydrogen ion concentration lower than that corresponding to about pH = 5.  The reaction may be performed at 0-100 DEG  C.  In examples: (1) polyvinyl alcohol is heated with 2-methylcyclohexanone in solution in alcohol and benzene in the presence of sulphuric acid; (2) polyvinyl acetate is heated with cyclohexanone in alcoholic solution in the presence of sulphuric or hydrochloric acid; the product may be employed in the manufacture of lacquers and moulding compositions; (3) polyvinyl alcohol is heated with cyclohexanone in aqueous solution in the presence of sulphuric or hydrochloric acid; an aqueous solution of the product may be employed as an auxiliary agent in the textile industry; (4) polyvinyl butyrate (obtainable by reacting acetylene with butyric acid in the presence of boron fluoride and mercuric oxide, and polymerizing the vinyl butyrate so produced in known manner) is heated with p-chlorocyclohexanone in alcoholic solution in the presence of sulphuric acid; the product can be used in the manufacture of lacquers and moulding compositions; (5) polyvinyl alcohol obtained by partial saponification of polyvinyl acetate until about half the acetyl groups remain is heated with a -oxotetrahydronaphthalene in alcoholic solution in the presence of sulphuric or borofluoroacetic acid; the product is suitable for the manufacture of artificial materials; (6) polyvinyl alcohol is condensed with cyclohexanone in solution in 60 per cent sulphuric acid at 0 DEG  C.; the product can be used in the manufacture of moulding compositions.  Other ketones specified as starting materials are 3-methylcyclohexanone and 4-ethylcyclohexanone.

Title: Improvements relating to optical systems
Inventor: ASKEW JOSEPH HORDON
IPC: G03B17/14
Filed: 1962-09-12
Abstract: 989,904. Automatic speed control. EVERSHED & VIGNOLES Ltd. Sept. 4, 1963 [Sept. 12, 1962], No. 34844/62. Heading G3R. [Also in Division H2] In an electric servomotor operated focussing system for a zoom lens the control signal is modified by a square law potentiometer positioned by the zoom control so that the sensitivity of the focussing system is constant throughout the range of the zoom control. A focussing control signal is derived from a hand driven A.C. or D.C. tachogenerator T1 across which is the square law potentiometer 5, the output of which comprises a desired speed signal which is balanced against an actual speed signal from a second tachogenerator T2. Thus, the servomotor M runs at a speed and for a time corresponding to the movement of T1 and the focussing mechanism, driven by shaft 8, takes up a required position. The slider 14 of potentiometer 5 is driven by the zoom control so that a given movement of T1 has a greater effect at low focal lengths than at high ones, which corresponds to the optical characteristics of the lens. The square law is not continued to the end of the potentiometer track to ensure that the minimum signal is great enough to overcome friction. The feedback tachogenerator T2 may be replaced by a potentiometer whose output is differentiated to give a speed signal.

Abstract: 834,122. Batteries. CORSON Inc., G. & W. H. Nov. 14, 1956 [Nov. 14, 1955], No. 34895/56. Drawings to Specification. Class 53. A current-generating cell for low temperature operation but also suitable for use at high atmospheric temperatures has an electrolyte comprising liquid ammonia with a material dissolved therein to render it conductive and to ensure that at least the anolyte portion comprises ammonium ions. The solute may be an ammonium salt or ammonium hydroxide, the salt being added as such or formed in situ by the addition of an acid; similarly, the ammonium hydroxide being added as such or formed in situ by the addition of water. Preferred salts are ammonium thiocyanate and ammonium perchlorate but the Specification lists many others. In addition to the above-mentioned solutes, the electrolyte may comprise salts of any metals sufficiently soluble in liquid ammonia, particularly those of the metals above iron in the electrochemical series and those of the alkali and alkaline earth metals. Of the many metals listed lithium is stated to be particularly advantageous. The anolyte and catholyte portions of the electrolyte may be identical or they may contain different salts and be separated by a porous or permeable diaphragm thereby permitting the employment of the invention claimed in Specification 794,970. In another arrangement the electrolyte as a whole or the anolyte or catholyte portion is confined in a capsule which is ruptured when the cell is required for use. Triaxial diagrams comprising Figs. 1, 2 of the drawings indicate suitable proportions of the electrolyte constituents. For significant current capacity there must be at least 1 mol. per cent of solute and 0.1 mol. per cent of ammonium ions in the anolyte. The anode may be of any metal above iron in the electrochemical series and particularly of the alkali and alkaline earth metals, one particular anode described being in the form of a paste or liquid containing lithium which may float on the electrolyte. Alloys of lithium may also be used. The depolarizing cathode may comprise a highly porous conductor of carbon or metal; alternatively a chemical depolarizer such as manganese dioxide may be used but many other examples are given. The cathode conductor employed in conjunction with the depolarizer may be of carbon, platinum, boron, zirconium or tantalum. The Specification describes in detail seven particular constructions of the cell. Specification 642,034 is referred to.
