Title: A new or improved race game apparatus
IPC: A63F9/14
Filed: 1920-10-19
Abstract: 175,687. Winters, J., and Rolinson, T. W., (trading as Ingenious Sports Specialists). Oct. 19, 1920. Race games, mechanical.-In a power-driven race game apparatus hedges or other obstacles are arranged across the tracks of the horses, &c., which are mounted on wheeled carriers fixed to driving-belts moving under the control of the players, cams being provided upon guide-rails beneath the tracks to cause the horses apparently to jump over the hedges. In the form shown in Fig. 1 each horse 3 is pivotally attached to a carrier fixed upon an endless band 7 and is guided by rollers 10 running on a guide-rail 8 provided with cams 9. A notched track acting on a wheel 12 gives a galloping appearance to the horse. The band is driven by means of a clutch 14, 14<a>, Fig. 2, band 25, expanding pulley 24 and motordriven shaft 21. Each player manipulates a pair of reins 30 attached to a corresponding lever 29. The movements of the lever 29 are transmitted by a cord 31 to an irregular cam 40 which actuates a lever 41 so as to vary the expanding pulley 24 and thus vary the speed of the band 25 and the corresponding horse. In starting a game, an attendant pushes in a rod 48 and thus couples up the clutches 14, 14a of all the horses and at the same time draws up a starting-gate 57. The players manipulate the reins 30 to obtain maximum speed for their horses, which move along the tracks and are caused by the cams 9 to rise and apparently jump the hedges 2. The horses, as they arrive at the ends of the tracks, complete electric circuits and their numbers are displayed upon a board 58 in known manner. In a modification, the cord 31 actuates the lever 41 by means shown in Fig. 9 comprising arms 34, 40a and a grooved plate 40. The tracks may be oval or circular instead of straight. The horses may be mounted on telescopic standards. The jockeys may be loosely seated and electromagnets may be arranged along the tracks under the control of the attendant so as temporarily to unseat the jockeys.

Data inputs to the status triggers are derived from external sources 31,32, microinstruction flag bits 33, and a data bus 20. There are as many columns of status triggers 24 as there are modifiable bits in the address input to control store 1 and corresponding bits of the next control store address are supplied from outputs 37 of the triggers 24. Other outputs of triggers 24, individual 35, or combined 36, form system control signals. The arrangement allows one row of triggers to be set while another is read, and status signals may be supplied sequentially over input 32 for setting different registers 25-28 so that fewer input leads are required.

Title: Improvements in or relating to the preparation of cyclic 1,2-ketols having from 10 to 18 carbon atoms in the ring
IPC: C07C35/02
Filed: 1947-11-05
Abstract: Cyclic 1,2-ketols having 10 to 18 carbon atoms in the ring and free from further free keto and free hydroxy groups as well as from double bonds in the a ,b -position are made by slowly adding to a liquid alkali metal in a heated inert solvent an ester of a monohydric aliphatic alcohol ester containing not more than ten carbon atoms and of a dicarboxylic acid whose carboxyl groups are separated by a chain of 8 to 16 carbon atoms and which does not contain free keto or free hydroxyl groups or have any double bond in the a ,b -position and treating the mixture first with an alcohol and then with water, the whole process being carried out in a substantially inert atmosphere (cf. U.S.A. Specification 2,228,268).  Examples and tables describe the reaction of sodium in hot xylene in an atmosphere of dry absolute nitrogen (followed by treatment with alcohol and then with water) with (1) the dimethyl or diethyl ester of the ethylene glycol ketal of 8 - ketopentadecane - 1,15 - dicarboxylic acid to give, after hydrolysis of the ethylene glycol ketal grouping with alcoholic hydrochloric acid, cyclo - 10 - keto - heptadecanol - 1 - one-2 which is acylated with 3,5-dinitrobenzoyl chloride; (2) diethyl or dimethyl sebacate to give cyclodecanol-1-one-2, which may be converted to its oxime; (3) the diethyl ester of brassylic acid, to give cyclo-tridicanol-1-one-2, which may be converted to its oxime; (4) the diethyl or dimethyl ester of tridecamethylene-1,13-dicarboxylic to give cyclopentadecanol-1-one-2, which may be converted to its oxime; (5) diethyl or dimethyl thapsiate to give cyclohexadecanol - 1 - one - 2; (6) the diethyl ester of 1-methyl-1,13-tridecanedicarboxylic acid to 3-(or 13-) methyl-cyclopentadecanol-1-one-2.  Other starting materials listed are the dimethyl ester of hexadecane-1,16-dicarboxylic acid and esters of pentadecane-1,15-dicarboxylic acid, and 2-methyl-tridecane-1,13-dicarboxylic acid.

Title: Agitating mechanisms
Inventor: PARRY KENNETH CHARLES
IPC: B01F11/00
Filed: 1949-11-18
Abstract: 669,677. Mixing appliances. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 15, 1950 [Nov. 18, 1949], No. 29541/49. Class 86 An agitating mechanism to impart a rocking motion and a repeatedly reversed rotary motion to fluid filled vessels loaded into it comprising a frame, a carriage mounted to rock with respect to said frame, driving means to rock the carriage, vessel holders on the carriage permitting rotation of inserted vessels, a spindle rotatable in bearings in said carriage and having couplings for rotating the inserted vessels about their rotational axes, a spindle extending along the carriage rocking axis and a coupling between said spindles. As described a polygonal carriage 15 is rocked about a hollow spigot 11 by means of a motor driven crankshaft 6 acting through a pivoted arm 7, a toothed quadrant 9 and a pinion 10 carried by the spigot 11. A fixed shaft 12 extends through the spigot 11 and carries a bevel gear wheel 13 which engages a bevel gear wheel 30 on a rotatable shaft 29 in the carriage. A large gear wheel 28 carried upon the other end of the shaft 29 engages a number of gear wheels 27 which are connected to sockets 25 each of which receives one end of a pipette 26 which is to form a vessel for the substance to be mixed. The other ends of the pipettes are received by rotatable cups 22 in spring loaded slides 20. The arrangement is such that by means of the bevel gears 13, 30 the rocking motion of the carriage imparts rotary reciprocation to the shaft 29 which in turn, through the gears 28, 27 reversably rotates the sockets 25 and the pipettes inserted therein. In modifications a crank linkage may be provided between the rotatable spindle in the carriage and the rotatable sockets for the vessels. The spindle extending along the rocking axis of the carriage may also be rotatable so that an additional component of rotation may be given to the vessels.

Title: Self correcting pulse generating clock
IPC: H04L7/033
Filed: 1966-07-01
Abstract: 1,137,769. Automatic phase control systems. INTERNATIONAL BUSINESS MACHINES CORP. 1 July, 1966 [13 July, 1965], No. 29594/66. Heading H3A. At a data receiving station a generator 10 feeds a chain of bi-stable devices 1-5 to produce clock pulses which are compared in phase with input signals, error signals causing adjustment of the dividing chain to restore synchronism. If an input pulse on line 27 occurs when trigger 4 is OFF, the control trigger 23 is turned ON and subsequently an additional pulse is fed to the divider chain via gates 26 and 33. If an input pulse on line 27 occurs when trigger 4 is ON, the control trigger 19 is turned ON and a subsequent pulse through gate 25 and inverter 35 blocks gate 36 thereby blocking one drive pulse in the divider chain. The gates 16 and 20 with inputs as shown open the respective gates 18 and 22 for 15/32 of a cycle each, the remaining 2/32 of a cycle being centred on a null point.

Title: Improvements in or relating to tape recorders and reproducers
IPC: G11B15/70
Filed: 1959-08-31
Abstract: 925,770. Endless tape recorders. L. H. KEELER, R. W. SHAW, J. C. FONDA, R. CROSS, R. E. MESSMER, and J. F. DONOHUE. Aug. 31, 1959 [Aug. 29, 1958], No. 29649/59. Class 40 (2). A double-faced endless tape 9, spliced into a Mobius loop and carried in an interchangeable magazine 50, is loadable into an elevating support 17 carrying heads 100 staggered across the tape width and selectively switched into transducing relation with separate tracks on the tape. A hand-lever 80 and cam-shaft 18 sufficiently raise the support 17 clear of the upper end of a capstan 15 to permit loading of a magazine through an aperture 21 in the machine case; at the same time, a further cam 70 on the cam-shaft 18 disengages a pinch-roller 71 and tape-contacts 91, 92, which provide headswitching and auto-stopping facilities. An apertured tape-guide, Fig. 12, clears a path for the tape as the support 17 is lowered, whereupon the heads 100, urged by a spring 47, resiliently engage the tape. The tape is stored on a sloping turntable 53 which is drivingly engaged with a pin 16 in the lowered position of the support 17. In another embodiment (Figs. 18-25, not shown), the heads are fixed and a tape guide is fixed to and resiliently urged towards the heads. The two-stage beltgear driving the capstan 15 from a motor 14 and the tape/head pressure means are particularly related to the elimination of interference due to vibration when the machine is used as a long-playing entertainment/information apparatus in aircraft.

Title: Improvements in or relating to high-pressure spray guns
IPC: B05B9/01
Filed: 1966-07-01
Abstract: 1,094,498. Spray-producers. WOMA-APPARATEBAU WOLFANG MAASBERG & CO. G.m.'b.H. July 1, 1966 [Nov. 27, 1965] No. 29655/66. Heading B2F. A hydrostatic spray gun comprises a liquid inlet tube 6 leading to a pressure chamber 9, an auxiliary valve 25 of small seating diameter controlled by a trigger 2 which is loaded by a spring 34 so as to close the valve 25 against the pressure of the liquid in a chamber 10a connected to the chamber 9 by a conduit 14, and a port 27, and a tubular main valve 12 controlling the liquid flow to the nozzle 5 which main valve is normally held in the closed position by the pressure of the liquid supplied to the gun but which, on actuation of the trigger to operate the valve 25, is urged to the required open position by the liquid pressure. The valve 12 is provided with a pair of pistons 19 which operate in a bore 10, and with two radial ducts 19a, 20. Liquid in the chamber 10a acts on piston 19 to maintain the valve 12 closed since the effective area of the piston is greater than the annular area of the conical end of the valve 12. When the valve 25 is retracted, assisted by the liquid pressure in the chamber 10a and opposed by the spring 34, the chamber 10a is connected to the atmosphere via bore 13 in valve 12, bore 4a, and the nozzle 5. The pressure in the chamber 9 is thus effective on the end of the valve 12 to move it to the right. Back pressure caused by the nozzle constriction assists the movement to the right, and liquid flows through the bore 20 and acts on the other piston. When the trigger is released the spring 34 closes the valve 25, pressure builds up in the chamber 10a, and the valve 12 is moved to the left into its closed position. The nozzle 5 may be changed for one having a different diameter bore.

Patent GB-796359-A (GB)
Title: A new salt of phenoxymethyl penicillin and methods for its production
Inventor: NIELSEN ERLING JUHL
IPC: C07D499/16
Filed: 1955-10-19
Abstract: The invention comprises a crystalline calcium salt of phenoxymethyl penicillin of the formula Pen2Ca, where Pen represents the phenoxy methyl penicillin ion C6H5OCH2C9H10N2O4S, said crystals containing 4 to 5 per cent water of crystallization.  The salt is prepared by adding calcium hydroxide or a calcium salt to a solution of phenoxymethylpenicillin or a salt thereof in the presence of sufficient water to provide the water necessary for crystallization. A solution of the free acid in, e.g., butyl or amyl acetate may be treated with an aqueous solution or suspension of calcium hydroxide or with a calcium salt such as the acetate in which the acid has a lower dissociation constant than that of phenoxymethyl penicillin acid.  In the case of water-soluble salts, e.g. sodium, potassium, ammonium or amine salts of phenoxymethyl penicillin and, e.g., calcium chloride, the reaction may be carried out in aqueous solution, if desired, in the presence of a buffer.  Examples are given of the preparation of the calcium salt of phenoxymethyl penicillin from the potassium, sodium, ammonium, diisopropylammonium, tertiary butyl ammonium, isopropylammonium, N,N - dimethyl - beta - hydroxy ammonium, 3 - methoxypropyl ammonium and cyclohexylammonium salts of phenoxymethylpenicillin and from the penicillin free acid. Calcium phenoxymethyl penicillin may be used injected to form a "depot" penicillin or may be administered orally (see Group VI). Reference is made in Provisional Specification to Specification 643,514.ALSO:Medicines for parenteral or oral administration comprise a crystalline calcium salt of phenoxymethyl penicillin containing 4 to 5 per cent water of crystallization (see Group IV (b)) and having a solubility in water at 20 DEG  C. of 1.1 per cent and a pharmaceutical carrier or diluent.  The stability of injections comprising aqueous suspensions of the calcium penicillin is increased by the addition of calcium ions, e.g. as calcium chloride.  The injections may also contain (a) surface active suspending agents such as lecithin, cetyl pyridinium chloride and "Tweens" (Registered Trade Mark), and (b) viscosity improvers such as carboxymethyl cellulose, polyvinyl pyrrolidone and gelatin.  In an example, calcium phenoxymethyl penicillin is coated with an ether solution of lecithin, the solvent removed and the coated salt suspended in an aqueous solution of carboxymethyl cellulose containing phenylmercuric acetate.  Oral preparations may be in the form of pills, tablets or capsules.  In an example, a tablet is prepared from calcium phenoxymethylpenicillin, starch, kaolin, gelatin and talc. Reference is made in the Provisional Specification to Specification 643,514, [Group IV(b)].

Title: Improvements in or relating to ammonium nitrate and compositions containing it
Inventor: TAYLOR AMBROSE GEORGE
IPC: C05C1/02
Filed: 1956-10-08
Abstract: <PICT:0819673/III/1> The production of ammonium nitrate of reduced bulk density, used in the manufacture of explosive compositions, comprises feeding an aqueous solution of ammonium nitrate from a reservoir into a trough in which there is disposed a drum, rotating about a horizontal axis, and having its circumference partially submerged in the solution, which is maintained at a concentration not exceeding 80 wt. per cent with respect to ammonium nitrate and at a temperature above the saturation temperature of the solution. The surface of the drum is cooled by internal cooling means thereby resulting in the formation of a mat of crystalline ammonium nitrate on the cooled surface of the drum, the mat of crystals is removed mechanically and the crystals are separated from adherent mother liquor and dried at a temperature not exceeding 60 DEG  C.  Aqueous ammonium nitrate solution 73-75 wt. per cent concentration is gravity-fed into trough 5 from a reservoir 1 which contains a steam-coil 2 to maintain the temperature of the solution above its saturation temperature.  Drum 9 which contains an annular space 15 supplied from 16, through conduits 14 and hollowed shaft 8 with cooling fluid, e.g. water or refrigerated brine, is immersed up to 1/3 of its circumference in the solution in 5 and is rotated.  The rate of feed from 1 is controlled by 4 such that the liquid in the trough is maintained above the saturation temperature, and ammonium nitrate crystals with mother liquor collect on the surface of drum 9 to be removed by a stationary knife edge.  After centrifuging to remove excess liquor the crystals are dried in a stream of warm air at a temperature not exceeding 60 DEG  C.  The excess liquor is returned to the reservoir 1 where it is utilized in the preparation of fresh ammonium nitrate solution of the required concentration.  In order to reduce the tendency to cake, the initial aqueous solution of ammonium nitrate may be treated with a small proportion of an anti-setting, crystal habit modifying agent, e.g. a salt of pararosaniline polysulphonic acid, for example acid magenta, a salt of methylene bis-monomethyl naphthalene sulphonic acid such salt being soluble in ammonium nitrate solution, or a salt of the condensation product of one molecule of formaldehyde and two molecules of an unsubstituted naphthalene monosulphonic acid such salt also being soluble in ammonium nitrate solution. Specifications 625,077, 627,680, 665,478, 743,602 and 800,794 are referred to.
