Title: Improvements in golf practice device
IPC: A63B69/00
Filed: 1944-10-19
Abstract: 585,634. Golf-practising devices. CLARKE, S. G. Oct. 19, 1944, No. 20279. Convention date. Oct. 21, 1943. [Class 132 (ii)] A golf-practising device has means for projecting a ball over a miniature course, the means being actuated through a gear train by striking another ball connected to the gear train, and the direction of projection being varied by the direction of the stroke: Mounted on a vertical pivot on a standard 7, beneath a platform 3, is a bracket member 9 having a web 8 supporting the gear train, one end of which is connected by an arm 5 carrying a ball 6 to a clutch member 18, the other end having a radial arm 24 moving in a slot 27 in a trough-shaped member 25 which carries a golf ball and is also supported by the web 8. The player stands on the platform 3 and strikes the ball 6, causing the arm 24 to rotate comparatively slowly and strike the galf ball. The rotation of the arm 24 can be stopped by pressing an end portion 31 of a member 30 pivoted under the platform and normally held clear of the arm by a spring 32. The pivot on the stand 7, the centre of the ball 6, and the longitudinal centre line of the course are in alignment, so that the bracket 9 will swing on the pivot if the strike is not a true one. The course slopes up towards a green 29 so that the ball will roll back to the starting point and will be guided into the trough 25 by guides 33 and 34.

In a linear assembly of such cases there is only one cover panel 40, Fig. 1, outer edges of the end walls 34, 35 having recesses (48), (49), Figs. 3, 6, receiving ridges (44), (45) on the panel 31 of the next case 30, the last case recesses receiving ridges (46), (47) on the cover panel 40. The assembly is held together by retaining members 56 extending through aligned grooves 55, Fig. 2, defined between flanges 53, 54 on walls 34, 35 and on panel 40. In a tape player, the assembly is indexed to bring a required cartridge adjacent an operative position by a drive engaging teeth 39 on walls 35, or engaging teeth on one of said retaining members (70), Figs. 12, 13 (not shown), and then the selected cartridge is moved up or down to said operative position, ledges 38 on fingers 37 normally supporting the cartridges. The assembly may have a top cover (75), Fig. 9 (not shown), with indicia (76) which are electronically scanned during indexing. Similar cases, but each having a respective cover panel (40a), Figs. 14-16 (not shown), may form a circular assembly in which the cases are supported by upper and lower discs (85), (88) by pins (83), on arms (82) extending outwards from each end wall (35a), engaging in holes (84) in disc (85), and drive ribs (86) on end walls (35a) engaging in peripheral notches (87) of disc (88). A tape player may have two units each with a ten cartridge storage assembly and a push button control logic arranged so that continuous loop tapes are played back from the two units alternatingly, each unit performing a cartridge indexing operation in its non-playing periods.

[Class 37] In a multi-range A.C. and D.C. measuring instrument as claimed in the parent Specification, the major proportion of the available current on the lowest D.C. range is passed through the movement, the values and arrangement of the components being chosen, still in accordance with the principles of the universal shunt, so that the resultant ampere-turns values in the transformer cancel out, or substantially cancel out. Fig. 2 is an effective circuit diagram in which the switches have been omitted and the combined transformer and resistance sections of the shunt c are shown as a pure resistance. The D.C. connections of the movement are shown in full lines and the A.C. connections in broken lines. A current Io to be measured is fed between a terminal A and a tapping h, a series resistance m being short-circuited for all ranges from Io upwards. The same current is fed to the movement a on A.C. and D.C. for all ranges, a shunt o being provided to shunt away from the movement a on D.C. readings the same proportion of current as is lost in the rectifier on A.C. The series resistance m may have a value rk =rc - Ro - Rk, where rc is the resistance of the shunt o, Ro is the resistance of the portion Ah of the shunt c and Rk is the resistance of the remaining portion h n of this shunt. Specification 423,199 also is referred to.

Abstract: 905,048. Refrigerating. GARRETT CORPORATION. June 10, 1960 [June 22, 1959], No. 20595/60. Class 29. An air cooling device includes a vortex tube 1 (Fig. 1) having an inlet 2, a hot tube 3, a cold outlet 4 for cooled air, means for bringing water into heat-exchange relationship with the outside of the hot tube 3 to cool it and means 5 for bleeding air from the hot end of the hot tube and bringing it into contact with the water to effect cooling by evaporation. In operation bleed air passes through openings 5 into a chamber 12 beneath a porous partition 7 which causes the air to pass up through a water column 8 in the form of very small bubbles which cool the water by evaporation. Air and vaporized water escape through spray baffles 11. In a modification, shown in Fig. 2, a small portion of the bleed air passes through openings 27 and lifts water in an annulus chamber 22 to feed cooling water downwardly over a series of baffles 29, 31 through which the major portion of the bleed air passes upwardly. In a further modification the main portion of the air is caused to flow through a passage which bypasses the pool.

The capacitive element 3 is mounted on a frame 11, 12, 13 and the assembly positioned in an apertured box like frame 5, Fig. 1 (not shown) the sensor assembly being held together by a rivet 15 passing through an insulative tube 14 extending through holes 25 in the side members 11, 12 centre member 13 and the element 3, the end of the rivet 15 having enlarged ends 16, 19. The electrode 21 is of smaller area than the coterminous core 20 and electrode 22 to prevent the electrodes shorting. The electrode 21 is also at a sufficient distance from the transverse edge of the core 20 so that when the assembly is clamped together its entire surface is exposed to the environment being tested. Electrode 21 is provided with a downwardly extending conductive tab 27 which when the sensor element is assembled in the frame is pressure contacted with contact 30, 31 on the middle plate 13 to provide an electrical connection. Similarly electrode 22 is provided with a blob 28 of conductive material which is contacted with contact 32, 34 on side plate 12. In an alternative arrangement Figs. 6-9, (not shown) electrode 21 is on the outer surface of the sensor 3 after it has been bent into the shape of a U, reinforcing strips of dielectric material being positioned along the longitudinally extending edges of inner electrode 22 to prevent curling at the edges. The electrodes' outer surfaces may be hydrolysed, Fig. 10 (not shown) to increase the rate of response. To prevent cracking an additional layer of dielectric material may be applied over the smaller electrode 21 which layer is coterminous with the core 20, the connection tag 27 in this case extending through the dielectric, Fig. 11, (not shown). The sensor may be connected in a Wien bridge circuit, Fig. 12 (not shown) A.C. circuit or a charge time circuit. Methods of making the sensor 3 are described.

The aqueous acid solutions may be those obtained by filtering culture media of fungal strains. The pH may be adjusted by addition of an acid or base. The activated carbon may be admixed with a filter material. After the adsorption step, the carbon may be washed with water to remove water-soluble impurities. Aqueous or alcoholic ammonia provides a suitable base solution.  The eluate may be extracted with a water-immiscible organic solvent, prior to evaporation, to remove any indole alkaloids in the solution.  The examples describe the separation of lysergic, 9,10-dihydro-lysergic, 6-methyl-D 8,9-ergolene-8-carboxylic and lumilysergic acids from aqueous solutions thereof.
