Title: Improved means applicable for use in practising billiards and similar ball games
IPC: A63D15/00
Filed: 1928-11-20
Abstract: 325,521. McCrea, H. M. Nov. 20, 1928. .4ddition to 303,218. Billiards and croquet practising appliances.- A modification of the parent Specification for practising billiards, croquet and similar ball games comprises a sector or quadrant shaped disc part a having markings of angular degrees thereon and having at the centre of the arc means for holding a pair of arms d and b. The arm d is adapted for angular movement over the face of the quadrant and the arm b may likewise be adapted for such angular movement or may be fixed in relation to the quadrant as shown. An indication arm f is rigidly attached to the disc a at an angle of 90‹ with the straight edge of the disc, or is rotatably hinged to the joint of the arm d and b. The arms are adapted to be held in their adjusted angular position by clips orother tightening means, and may be provided with hinged, pivoted or telescopic extensions. In the device, for example, to play a half-ball pot shot, the devices is placed so that the ball P to be potted occupies a position exactly in the angle formed by the arm b and the indicator arm f, while the arm d is moved angularly as for a half-ball shot so as to point to the selected pocket P<1>. The arm b now indicates the line of aim for the striker's ball s and the device may be removed from the table and the stroke made.

Title: Concrete structures with metal linings
Inventor: HUGGETT LEONARD GEORGE
IPC: C04B41/69
Filed: 1963-08-28
Abstract: Concrete structures are provided with a corrosion resistant metal lining in the form of foil or thin sheets, which is secured to the internal surface of the structure by means of adhesive, the direction of overlap of the sheets being such that the material in the structure will drop off the metal into the interior of the structure rather than into gaps between the metal and the concrete.  The metal may be aluminium (e.g. 0.010-0.015 inch thick), aluminium alloy or stainless steel, and may be attached by a rubber resin adhesive.  An electric contact may be provided between adjacent sheets by soldering or welding. Examples of concrete structures are towers, prilling towers, reaction chambers, and containers.

Abstract: Ethylene and other ethylenic hydrocarbons are oxidized to ethylene oxide and other oxides in the presence of a silver catalyst, e.g. as described in Specifications 663,257 and 728,821, [both in Group III], which has been activated or reactivated by treatment with an aqueous alkaline solution of a hydrate or salt of the following:-hydrazine, an alkyl or aryl hydrazine, hydroxylamine, or an alkyl or arylhydroxylamine (see Group III).  In examples, a mixture of air and ethylene is passed at 250 DEG  C. over a silver-calcium catalyst which has been intentionally poisoned with a gas containing a halogen, a hydrogen halide, hydrogen sulphide, or sulphur dioxide and then reactivated with alkaline solutions of hydrazine sulphate, phenylhydrazine sulphate, and hydroxylamine sulphate.ALSO:A silver catalyst for the oxidation of ethylenic hydrocarbons is activated or reactivated by treatment with an aqueous alkaline solution of a hydrate or salt of the following:- hydrazine, an alkyl or aryl substituted hydrazine, hydroxylamine, or an alkyl or aryl substituted hydroxylamine Suitable compounds are the hydrate nitrate, formate, oxalate, or sulphate of hydrazine or of its methyl, ethyl, benzyl, phenyl, tolyl, or p-tolyl derivatives, or the hydrates or salts of hydroxylamine or of its methyl, ethyl, propyl, benzyl, phenyl, or p-tolyl derivatives.  The preferred concentration of the treating solution is 0..1-0.2M and the excess of alkali (e.g. sodium hydroxide) 0.02-0.1M.  Treatment may be for 30 minutes to 1 hour at about 50 DEG C., after which the catalyst is washed and dried. Before treatment, the catalyst may be intentionally poisoned by contact with a gas containing a halogen, a hydrogen halide, hydrogen sulphide, or sulphur dioxide.  The silver catalysts may be as described in Specifications 663,257 and 728,821 and may consist of alloys of silver with one or more of the metals calcium, magnesium, barium, and strontium, some of which metal has been removed by treatment with water or dilute acid.

As shown, a motor 7 of the slidable vane type is located in of the conduits 3, 4 between the servomotur 2 and a relay 1 of the pivoted jet type. The movement of the motor 7 is transmitted through gears 9, 10, 11 to a rack 12 pivotally connected to a restoring lever 20. A spring 21 connects the lever 20 to the jet pipe 1. The rack is centralised by a spring 15 which acts selectively on the rack through two levers 13a, 13b, the rotation of which is limited in one direction by stops 17, 18. After a regulation operation, the spring 15 acts slowly through the rack 12 and lever 20 to relieve the spring 21 of stress and so effect isodromic control the pressure difference caused by rotation of the motor 7 being equalised through the conduit 5. The rotary motor may alternatively comprise a series of radially arranged pistons and cylinders.

Abstract: A process for the preparation of polyene compounds, namely polyene compounds containing a 3,7-dimethylocta-1,3,5,7-tetraenylene radical, by reacting suitable triarylphosphonium salts with suitable aldehydes, consists in carrying out the reaction in a two-phase aqueous/organic solvent system, the organic phase being composed of an optionally chlorinated hydrocarbon which is not miscible with water and the volumetric ratio between organic phase and water being between 10:1 and 1:20. This allows extremely low reaction temperatures to be avoided without accepting low yields.

Title: Improvements in or relating to pulse circuit arrangements including bistable stages
IPC: H03K5/15
Filed: 1964-08-27
Abstract: 1,070,856. Associative stores. SIEMENS & HALSKE A.G. Aug. 27, 1964 [Aug. 27, 1963], No. 35081/64. Heading G4C. [Also in Division H3] A circuit arrangement is adapted to produce output pulses successively on selectably marked leads in response to input clock pulses. The arrangement is applicable to reading-out associative memories. First embodiment, Fig. 1. Each (except the first) of a series of bi-stable triggers K 0 -K 3  has an associated switch comprising a transistor TS1-TS3, the transistors normally being conductive but being turned-off in those stages which it is desired to mark. In operation, assuming stages 2 and 3 are thus marked, the triggers K 1 -K 3  are initially set to " 0 " and the trigger K 0  to "1," the output potential from side A of trigger K 0  passing via conducting transistor TS1 to energize a gate G2 which is primed by the marking potential applied to stage 2, thereby setting up trigger K 2  which is then Switched to " 1 " by the first clock pulse, this pulse resetting trigger K 0  to " 0." The output from trigger K 2  now sets up the trigger K 3  of the next marked stage. The second clock pulse resets trigger K 2  to " 0 " and switches trigger K 3  to " 1." Second embodiment, Fig. 2 (not shown). Each stage comprises a bi-stable magnetic core (K 0 -K 3 ), and associated transistors (Ts0-Ts3) connected by control windings (W 3 ) and feedback windings (W 4 ) to the associated cores. Switch transistors (Ts11- Ts13) are normally conducting but are switched off in stages where an output pulse is required. In operation, assuming stages 2 and 3 only are marked, an initial reset pulse on a lead (R) sets cores (K 1 -K 3 ) to " 0 " and the first core (K 0 ) to " 1." The first clock pulse on lead (T) switches the first core (K 0 ) to " 0," the associated transistor (Ts0) conducting during the switching period to produce a pulse which passes via a conducting transistor (Ts11) in the unmarked stage 1 to switch core (K 2 ) in the marked stage 2 by means of a winding (W 5 ). The next clock pulse resets this core (K 2 ) to " 0 " thereby producing a pulse in an output winding (not shown), and setting to " 1 " the next core (K 3 ) of the marked stage 3.
