Title: Axle and wheel or wheel hub assemblies for miniature gauge model railway rolling stock
IPC: A63H19/22
Filed: 1945-11-09
Abstract: 604,610. Bearings. PRITCHARD, S. C. Nov. 9, 1945, No. 29890. [Class 12 (i)] [Also in Group XV] A bearing for a wheel hub assembly for miniature gauge model railway rolling stock comprises a fixed axle member adapted to engage with the framework of the rolling stock, a pair of wheel hubs mounted upon the fixed axle member and separated by an intermediate spacing axle member and a group of bearing balls positioned adjacent each end of the wheel assembly, each group engaging a surface of the wheel assembly and a surface of the fixed axle member. A pair of wheels 10, Fig. 1, are assembled on a tubular spacing axle member 11 through which extends a fixed axle member 12. The rod 12 extends sufficiently to form annular bearing surfaces about which are arranged bearing balls 13 within recesses 14 formed in the outer surface of the wheel. Sleeve-like members 15 may hold the balls in the recesses, and in this case, Fig. 1, are themselves fixed to the ends of the fixed axle member 12, being held within boxes or brackets 17 which are part of the external framework. The bearing balls may be held by plates fixed or screwed to the wheels, in which case the sleeve members may be dispensed with, Fig. 2. The intermediate spacing axle member may be formed with cup-like flanges at its ends, Figs. 3 and 4, or it may be integral with the wheels, Figs. 2 and 8. The fixed axle member may be replaced by stub axles attached to the framework, Figs. 7 and 8, or the stub axles may be formed with cup-like ends, the balls being retained between the cup and the spacing member, Fig. 9. Alternatively, the fixed axle member may be a hollow tube 52, Fig. 10, formed with cup-like ends 53, the bearing balls 54 resting between the cups and the hub portions 55 formed on the wheels 50. The member 52 is attached rigidly to the arms 58 of the bracket 57. Modifications are described in which the balls run directly on the axle rod, the fixed axle member becomes hollow cups on the depending arms of the bracket, and cupshaped members are attached to the wheels to retain the bearing balls.

Title: Improvements in or relating to very short wave aerial systems
IPC: H01Q19/17
Filed: 1957-09-26
Abstract: 814,355. Aerials. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Sept. 26, 1957 [Oct. 1, 1956]. No. 30219/57. Class 40 (7). An aerial system for horizontally polarized energy designed to have a radiation polar diagram which, in the vertical plane, approximates to a cosecant squared curve, consists of a parabolic reflector 5 fed by a plurality of radio horns 1 to 4, means being provided in the mouths of the horns to narrow their individual polar diagrams to give the required resultant radiation pattern. As shown, the horns are placed closely adjacent to each other in the focal plane of the reflector; all being directed to illuminate the same zone. They are fed to illuminate the reflector in phase. If, as is known, the horns are used without modification to feed the reflector, the width of their primary patterns is such that their individual secondary patterns are too sharp and do not overlap adequately, thus giving marked low intensity regions in the resulting composite pattern. In the preferred embodiment of the invention, each horn has a metallic rod conductor 7 placed centrally across its mouth parallel to the electric vector and is provided with a dielectric member shaped as a segment of a cylinder with its flat face in, and covering, the horn mouth. These elements narrow the primary patterns of the horns and the individual secondary patterns are correspondingly broadened to give a smoother composite cosecsquared pattern.

Abstract: 297,409. Blum, H. L. Sept. 21, 1927, [Convention date]- Liquid meters.-In a liquid meter comprising a group of cylinders the ports to which are controlled by an annular valve which is rotated eccentrically in a circular orbit, and is operated by the movement of a swash plate actuated by the pistons, the cylinder ports are elongated in the direction of the circumference of the valve, a seal is provided for the swash plate adjustment, and an ejector tube is provided for draining the meter. The cylinders 6, Figs. 1 and 6 are formed in a block 7 depending into the lower part 2 of a. casing, the upper part 1 of which encloses the valve and counting- mechanism, and is formed with an entrance 4 and exit 5 separated by a partition 56. The ports 9, of elongated form, are controlled by an annular valve 10 consisting of upper and lower members 78. 79, sliding between flat surfaces 80, 81 and resiliently pressed apart by a spring 88<1>, which is mounted in a bush 91 on the lower part 78 and engages the lower edge of the upper part 79; the joint between them is rendered liquidtight by a leather ring 92. The lower member 78 is provided with lugs 90 for centering the upper part, and is carried on a crank-pin 42 which also operates the counting-mechanism 54, and is mounted on an arm 40 on a central shaft 36; the crank-arm 40 is fitted with a counter-weight 41.

The swash plate 15 rides on a track plate 23 supported on rods 30 passing through slots in the swash plate, rotational movement of the latter being prevented by means of a slidably-mounted forked head 68 engaging a squared part 67 of one of the rods; this movement may also be prevented by passing the rods 30 through bushed holes in the swash plate. The swash plate is connected to the piston rods 12 by means of ball joints 13. The pistons consist of leather discs 57, Fig. 3, with a flange 58. and a pair of strengthening metal members 59, 60. The lower part of the casing is drained by a pipe 95.

Title: Improvements in or relating to the production of sugar
IPC: C13B10/00
Filed: 1964-08-04
Abstract: <PICT:1031443/C6-C7/1> In extracting sugar from crushed sugar-containing plants, sufficient water is added to yield a mixture whose pH differs from 7, this mixture is passed through a substantially closed vessel and exposed therein to ultrasonic pulses generated by electric spark discharges in the mixture, which is simultaneously sterilized by the ozone produced. The ultrasonic pulses are regulated by varying the rate of flow of the mixture through the vessel or the intensity and/or frequency of the spark discharges. The mixture is fed, by a travelling belt 1, into a funnel 2 and conveyed, by a worm 8, into the upper end of a cylindrical vertical tube 6, through which the mixture passes and is discharged, by a worm 8a, into a vessel 12, kept at atmospheric pressure.  The tube 6 is kept filled with the mixture, as by rotating the worm 8a at the same speed as, or slightly slower than, the worm 8.  The tube 6 may be made of hard, resilient, synthetic plastics or resinous material, or of thin sheet steel lined with such material, and is preferably surrounded by a cushion  f air 5, contained in an air-tight cylindrical jacket 4, secured to the tube by conical parts 3 and 7.  Two electrodes 9 and 9a, e.g. of iron, are dispersed centrally in the tube 6, and their power leads pass, through pressure-tight, insulating bushes 10, to apparatus 11, which is provided with means for adjusting the inductance and capacity to regulate the frequency and intensity of the spark discharges and the ultrasonic pulses.  The treated mixture, received in the vessel 12, may be filtered conventionally to yield raw juice, which may be purified conventionally and then chilled to freeze-out sugar crystals.

Filed: 1958-09-24
Abstract: 898,902. Electro-luminescence. RADIO CORPORATION OF AMERICA. Sept. 24, 1958 [Sept. 30, 1957], No. 30547/58. Class 39(1). [Also in Group XL(b)] In an arrangement for reducing the delay time of conductivity of a photoconductive material on removal of impinging radiant energy, the polarity of the operating voltage is reversed immediately following the removal of the radiant energy. A light amplifying panel 30 includes an electro-luminescent layer 34 and a ridged photoconductive layer 38. Operating voltages are supplied via changeover switch 16 and rectifiers 40, 46 from a transformer 44 and the arrangement is such that alternate ridges of the photoconductive layer are supplied during one half cycle of the voltage supply and the remaining ridges during the other half cycle. When the photoconductive side of the panel is subjected to radiation the electroluminescent panel emits an amplified version of the incident image. On removing the incident radiation the delay time of the output image is reduced by reversing the polarity of the supply voltage by operation of switch 16. Uniformity of erasure is ensured by flooding the panel with light from source 23 immediately prior to the polarity reversal. Fig. 3 (not shown) illustrates the application of the invention to a light storage panel and Fig. 4 (not shown) illustrates an arrangement in which the rate of delay can be selected.
