Patent GB-329707-A (GB)
Abstract: 329,707. Ward, T. E. Feb. 26, 1929. Totalizators.-In a ball type of totalizator, the balls are released one (or two) at a time by means of a star wheel controlled by an electromagnetically operated escapement lever. In the form shown in Fig. 1 the column of balls E in a tube D rests on a tooth of a star-wheel A supported on a bracket C and projecting into the tube through a slot D<1>. Co-operating with the star-wheel is a bifurcated lever G connected by a rod I with the core of an electromagnet K and having pallet surfaces G<5>, G<6>, Q<7> to stop and release the wheel one tooth at a time. In a modification, Fig. 4, the star-wheel is compound, one part being six-toothed as in Fig. 1 and projecting into the tube and the other part, for cooperating with the escapement lever. having only three teeth. At each to-and-fro oscillation of the lever therefore the star-wheel permits two balls to fall. The star-wheel in Fig. 1 could be duplicated to allow a ball from each of two side-byside tubes to be released at one operation.

Abstract: 189,805. Beuret, L. E. Dec. 3, 1921, [Convention date]. Motor-cycles and the like; motors, mounting; fuel containers. - The engine is arranged above the rear wheel with its axis vertical. The crank shaft is connected by a chain to two pulleys arranged so as to engage on either side of a road wheel rim or a separate rim secured to the wheel. The engine is arranged as shown in elevation and plan in Figs. 1 and 2 with a flywheel of relatively large diameter so as to Increase stability. A chain passes over two chain pulleys 16, 17, also shown in Fig. 3, driving the road wheel and also over a chain pulley 27 driving the magneto. The shafts of the chain pulleys 16, 17 carry friction pulleys and are mounted on levers 22, 23 pivoted to the engine casing. A spring 24 presses the friction pulleys into engagement with a wheel or driving rim 25 and they are disengaged by a cable 26. With this driving arrangement, the ignition is automatically advanced and retarded as the friction driving pulleys are engaged and disengaged. An extension of the crank casing of the engine forms the fuel tank having a, filling opening 30. Several pairs of pulleys of different diameter may be used in turn to vary the speed ratio.

Abstract: 1,197,751. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 18 July, 1967 [29 July, 1966], No. 33023/67. Heading H1K.  A semi-conductor body 48 containing an integrated circuit is positioned in an aperture in an insulating support 42 so that contact pads on the body 48 engage the ends 46a of conductive strips 46 on the support 42, which ends 46a overlap the aperture. The outer ends 46b, which extend to or almost to the periphery of the support 42, are at least as far apart as the inner ends 46a and, in the embodiment shown, comprise lands to which are attached terminal pins 50 extending through the support 42 to enable the assembly to be plugged into a socket. Plastics encapsulant 52 encloses the assembly. In another embodiment tapering conductive strips (86), Fig. 8 (not shown), extend radially from a semi-conductor body (88) situated in a circular aperture (84) in the insulating support (82), and terminate at the four outer edges of the support (82). A heatconducting metal plate (90) is bonded to the lower faces of the support (82) and the body (88), electrically connected to or insulated from the body (88) dependent upon the nature of the bonding agent. Two such. supports may be bonded together to provide contact to electrodes (122a, 122b), Fig. 11 (not shown), on both surfaces of a semi-conductor body (120). A vacuum tool (152) may be used in this case to manipulate the body (120) between the two sets of conductive strips. A similar body may alternatively be situated in an aperture in a single insulating support (160), Fig. 13 (not shown), provided with conductive strips on both its surfaces. The strips (164) on one surface are identical with those of Fig. 8 (not shown), and are bonded directly to the electrodes on the semi-conductor body (120), but the strips (166) on the other surface stop short of the edge of the aperture and are connected to the corresponding electrodes (122b) by whisker leads (168). In certain embodiments the potting material is moulded about the assembly, while in others it is applied as a paste. In the remaining embodiments (Figs. 2 or 6, not shown), the outer ends of the conductive strips are spaced apart by the same distance as the inner ends, the inner ends of the strips overlapping a circular aperture in the insulating support and being regularly spaced around the aperture, while the outer ends all extend to a common edge of the support, which edge is free from the potting material to allow the assembly to be plugged into a printed circuit board connector.

Filed: 1932-11-23
Abstract: 393,495. Valve circuits. TELEFUNKEN GES. FœR DRAHTLOSE TELEGRAPHIE, 12, Hallesches Ufer, Berlin. Nov. 23, 1932, No. 33171. Convention date, Nov. 23, 1931. [Classes 39 (i) and 40 (v).] Relates to circuits comprising indirectly-heated valves of the type in which there is a discharge space between the cathode and heater, and in which grid biasing voltage is obtained from a resistance W in the anode-cathode circuit of the valve. According to the invention, the biasing resistance is so chosen that the voltage drop across it is large enough completely to saturate the electron discharge path between heater, and cathode, thus eliminating hum. The required grid bias is then obtained by a variable tapping on the resistance W, as shown.

Abstract: 432,939. Photographic projection printing-apparatus. DEBRIE, A. L. V., 111, Rue St. Maur, Paris. Nov. 19, 1934, Nos. 33236, 33237, and 33238. Convention dates, Nov. 17, 1933, March 6, 1934, and Nov. 3, 1934. [Class 98 (i)] In a machine for printing a number of positive kinematographic films from a single negative film, the source of light is arranged along the axis of a cylindrical drum over which the negative is passed, and the drum is slotted so that light passes out in radial direction on to the optical devices which direct it on to the positive film. As shown in Fig. 1, the negative film 1 passes from the feed reel 2 to the take-up reel 3 over the drum 5 which is slotted at 9, 9<1>. Light from a lamp 7, whose filament 6 lies on the axis of the drum 5, passes through the slots, and an image of the negative is formed on the positive films 13, 131 by the objectives 11, 11<1>. Alternatively to slotting the drum 5, screens 14 with slots may be mounted in front of the positive films. In a modification, a device comprising three prisms is arranged between the objective and the positive, and the corresponding beams are rendered parallel to one another, thereby enabling the positives to be mounted on coaxial drums. By these means, and by the use of two separate negative drums, separate sound and picture records can be simultaneously produced on the positive films. In the form shown in Fig. 7 the axis of the negative film drum 25 is perpendicular to the axis 38 of the positive film drums 37, and Wollaston prisms W are adapted to rotate the image in its plane through an angle of 90‹. Each prism is disposed between objectives 31A, 31B so placed that a parallel light beam is passed through the prism. Mirror or total reflexion prisms 40, 40<1> &c. are employed to bring the beams into parallel directions, and also serve to neutralize the image inversion due to the objectives.

Abstract: 673,719. Magnetic compositions. ALADDIN INDUSTRIES, Inc. Dec. 29, 1949 [Jan. 3, 1949], No. 33266/49. Class 38 (ii). A magnetic core suitable for use in the 76.5-108 Mc/sec. frequency range is made by combining cobalt and nickel ferrites which have been formed separately by heating cobalt and nickel oxides with iron oxide in about the molecular proportions of 1 of Co 2 O 3  or Ni 2 O 3  to 2 of Fe 2 O 3 . The ferrites produced by heating at 2000-2500 F. are powdered and mixed in equal proportions or with an excess of one up to 25 per cent with zinc ferrite similarly formed or with separate equal proportions of nickel oxide and iron oxide, and also with fairly small amounts of magnesium zirconate and vanadium oxide with further iron oxide to combine with the latter. The mixture is moulded with a resinous binder such as the reaction products of phenol-aldehydes, ureaaldehydes, vinyl polymers and copolymers, polyacrylates and polystyrene, heated to a compact body at 1800-2550 F. when the binder is burnt away, and cooled at about 100 F. per hour. Up to 25 per cent of the magnesium zirconate may be replaced by lead titanate. The core has good Q and low thermal drift. Specification 673,720 is referred to.
