Title: Producing sheet glass
IPC: C03B15/04
Filed: 1969-12-23
Abstract: 1,270,160. Drawing sheet glass. LIBBEY OWENS FORD CO. 23 Dec., 1969 [23 Dec., 1968], No. 62538/69. Heading C1M. In the production of sheet glass 17 by drawing upwardly from a bath 16 of molten glass through a forming zone 22 and deflecting the sheet about a bending member 25 into a substantially horizontal plane while separated from the member 25 by a fluid film through a slot 29, the sheet 17 is maintained at a substantially uniform temperature for deflection over member 25 by transferring heat from the newly drawn sheet to coolers 21 with a heat-absorbing surface 33, heat being conducted away from the surface 33 at a rate sufficient to maintain the surface at a temperature below that of the glass sheet and within the range 300‹ to 1000‹ F. In addition to the coolers 21, which are divided into compartments 39 through which cooling water is flowed, the sheet 17 may be protected by one or more insulating panels 34, 47, which may be positioned along a rod, as 35, as required and may be partially or completely rolled up on to rod 35. A pan of triangular shape, as shown in Fig. 2, or a single panel with triangular ends (Fig. 3, not shown) may be used, so as to blend their heat conserving effect inwardly from the edges of the sheet. They are preferably of quartz cloth or like flexible material but stainless steel or light-weight ceramic may be used. The coolers 21 preferably have the surface 33 formed by a layer of asbestos cloth painted with a black, high-temperature, paint. A conventional cooler 46 may be positioned below the roll member 25 to absorb heat therefrom. Heaters may be provided in chamber 22 if required and may be directed against the panels 34, 47 which are then of heat-reflecting material or the panels may incorporate electrical resistance heaters.

Abstract: 782,085. Optical sound reproducing apparatus. TELEFUNKEN GES. Nov. 18, 1955 [Nov. 19, 1954], No. 33057/55. Class 40 (2). A signal generator adapted to transmit a combination of frequencies selected from a relatively large number of different frequencies, comprises a record carrier having a plurality of optical tracks, each corresponding to a different frequency, a plurality of photo-electric pick-up devices, one for each track, means for producing constant relative motion between record carrier and pick-up devices, and means for selectively rendering a desired combination of signal frequencies effective without switching the signal circuits. In the embodiment described, the optical tracks are carried on a disc or discs 5 rotated by a motor 3, and the individual tracks are rendered effective by closing switches 8a to 8h, inclusive, in circuit with lamps 6a to 6h, respectively, which energize a common photo-electric cell unit 7 whose output is coupled to an external circuit 10 and amplifier 11. Adjustable diaphragms in the light paths or rheostats in the lamp circuits enable amplitude adjustments to be made to individual frequencies.

Title: Nuclear Fuel Pins
IPC: G21C3/28
Filed: 1979-03-15
Abstract: A nuclear fuel pin for a fast breeder nuclear reactor has a central fissile region 3 containing fissile material in the form of vibro- compacted microspheres and axial breeder regions 4 above and below the central region 3 containing fertile material in the form of pellets 10, 10a. The microspheres are of two sizes with the smaller microspheres packed into the interstices between the larger microspheres. To prevent intermixing of the material of the fissile and fertile regions a barrier layer 6 is located between the fissile region 3 and each breeder region. Each layer 6 comprises microspheres of fertile or fissile material having a diameter intermediate the diameter of the larger and smaller microspheres of the fissile region 3. The larger microspheres contain a mixed oxide of u and U while the smaller microspheres contain U oxide. The breeder pellets 10, 10a are of such a diameter that the annular gap between them and the wall of the fuel pin is insufficient to allow passage of the intermediate diameter microspheres. <IMAGE>

Title: Gas dryer/dehumidifier
IPC: F24F3/14
Filed: 1980-05-16
Abstract: An apparatus for dehumidification of gas consists of a moisture adsorbing medium (15) arranged in relative thin layers separated by electrical heating elements (43) for heating the adsorbing medium during regeneration thereof. The heating elements comprise a sheet material preferably having a printed circuit thereon. The adsorbing medium is arranged in one or more separate chambers (12) defined in a common housing (10) having an inlet (13) for gas to be dehumidified and an outlet (14) for dehumidified gas. In operation gas to be dehumidified flows from the gas inlet (13) through the majority of the chambers (12) and the adsorbing medium (15) contained therein. A small fraction of dehumidified gas is directed from the outlet (14) through the adsorbing medium in the remaining chamber or chambers towards the gas inlet (13), and the adsorbing medium in this chamber or these chambers is at the same time heated by the heating elements (43) in order to regenerate the adsorbing medium. At predetermined time intervals the chamber or chambers in which the regeneration takes place, are changed by means of a rotary valve (20). <IMAGE>

Title: Sealing device made of metal for a highvacuum closure
IPC: F16K1/34
Filed: 1980-11-24
Abstract: A sealing device for a high-vacuum closure, such as used in a high-vacuum valve, where the surfaces effecting the seal are formed of metal. In forming the seal, a sealing member extends between and into contact with a pair of laterally spaced sealing surfaces. The surfaces on the sealing member which contact the sealing surfaces are rounded and have a radius of curvature equal to half the dimension of the sealing member between the sealing surfaces when it first contacts the surfaces during the closing step. The sealing surfaces can be frustoconical or spherical. When the device is closed, sealing force presses the sealing member between the sealing surfaces so that a relative rolling action takes place. Only elastic deformation occurs when the seal is effected.
