Abstract: 574,827. Incandescent lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., and ALDINGTON, J. N. Feb. 11, 1944, No. 2593. [Class 39 (ii)] In a filament structure for an incandescent electric lamp comprising a number of parallel connected, electrically similar filaments 1, 2, 3, 4, between two spaced supporting members 11. 12, a common intermediate support makes substantially point contact with the filaments. The intermediate supports may consist of connected loops or of helices 5 of refractory metal wire which may be reinforced by metal rods 6 secured to the filament supports, as by a refractory insulating bead 14, or to the foot tube, and may be displaced from the plane in which the supports 11, 12 lie, e.g., as shown in Fig. 2. The filament ends may be welded directly to the supports 11, 12, or may be clamped in flattened tubes 15 welded to them. The filaments may be simple or compound helices in an inert gas or gas mixture. To compensate for convection effects the pitch of the upper filaments may be reduced.

Title: Improvements in or relating to magnetic recording media
Inventor: ANGOLD EDWARD BARNABAS
IPC: D01F6/08
Filed: 1953-01-29
Abstract: 759,486. Magnetic structures. THERMIONIC PRODUCTS, Ltd. Jan. 22, 1954 [Jan. 29, 1953], No. 2613/53. Class 38 (2). [Also in Group VIII] A method of importing a highly glazed operative surface to a magnetic recording medium in the form of a coating of magnetic particles in a binder anchored to a flexible backing, e.g. of paper, consists in heating a portion of an optically smooth surface of a continuously moving member applying the medium under pressure against the heated portion of the optically smooth surface and subsequently stripping the medium from the surface at a point displaced from the heated portion in the direction of movement of the member. As shown in Fig. 1, the magnetic recording strips are fed from spools 13, 14 between optically smooth surfaces 1a, 2a of two endless bands driven by a motor 8 and are rewound on spools 15, 16. The bands pass between heated pressure units 9, 10 having cavities for hydraulic fluid supplied under pressure from a pipe 23 and electric, gas or steam heating means. In an alternative form the endless bands are replaced by a slowly driven drum with a smooth surface, an idler roller being spring urged to press the strip against the surface of the drum. A heating pipe within the drum is connected to a supply of steam, perforations in the pipe directing the steam on to the line of engagement with the idler roller. The lower part of the drum is cooled by water within the drum. A feed roller for supplying the magnetic recording strip is positioned above the drum together with a receptacle for a softening agent. The strip adheres to the surface of the drum and rotates therewith until after passing the water cooling zone, the sheet then being stripped by a take-up roller.

Title: Ion-getter pump
IPC: H01J41/16
Filed: 1958-01-27
Abstract: 874,674. Discharge apparatus. HIGH VOLTAGE ENGINEERING CORPORATION. Jan. 27, 1958 [Jan. 26, 1957], No.. 2653/58. Class 39(1). An ion-getter pump for producing a high vacuum below 10<SP>-6</SP> mm. of mercury consisting of a casing containing an ion source and a vaporizer source for getter metals, particularly titanium, is characterized in that the ion source is created in one part of the casing and is in communication with the vaporizer source which is created in another part of the casing, there being no substantial restriction of the flow of gas between the two parts of the casing. In the arrangement shown, a layer of getter metal 5 is formed on the wall of a tube 1 by vaporization of titanium wires 4 wound on one or more hairpin-shaped wires 2 of high-melting-point metal such as tungsten. A connection 6 enables a specific potential to be given to the layer 5. The gas to be pumped which may bea rare gas, is ionized by a discharge device 3 of the Penning type. If a very high final vacuum of about 10<SP>-7</SP> mm. of. mercury or less is required, a heated cathode 8 is used. Otherwise, any other source of electrons, such as a radio-active preparation or a pointed cathode may be used. Other types of ion source may also be used. The vaporizer source may be directly or indirectly heated. A preliminary evacuation of the container 7 to a pressure of about 10<SP>-2</SP> mm. of mercury is effected by a backing, pump, and the getter metal 4 and tungsten wire 5 are outgassed by powerful heating. Thebacking pump is then removed and the discharge device switched on. In operation, the temperature of the vaporizer source may be maintained at a value below the vaporizing temperature of the getter metal except for repeated brief intervals when it is raised above that temperature. Owing to the separation of the vaporizer source and the ion source the electrodes of the latter are not contaminated by evaporated getter material.
