Title: Improvements in and relating to incandescent electric lamp filaments and methods of manufacturing the same
IPC: H01K3/02
Filed: 1933-05-01
Abstract: 418,989. Electric incandescent lamp filaments. ERBER, B., 49, Dittesgasse, Vienna. May 1, 1933, No. 12622. Convention date, May 7, 1932. [Class 39 (ii).] A filament for an electric incandescent lamp consists of a carbon core coated with the carbide of tantalum or of one of the metals of the tantalum group, produced by providing an independently manufactured carbon filament with a coherent tightly adhering deposit of metallic tantalum which is subsequently converted into the carbide. In making the composite filament a carbon filament is heated in a tantalum halogenous atmosphere, whereby metallic tantalum is deposited on the glowing carbon, the temperature preferably being such that tantalum carbide is not formed at this stage. After the desired thickness of coating is obtained the tantalum is converted into the carbide by the addition of carbon obtained either exclusively from the core or, for the greater part, from the outside. In the former case the tantalum coated carbon core is heated in an atmosphere of rare gas or in vacuo, while in the latter the filament is heated in an atmosphere containing one or more carbon compounds. The heating may be effected either by the passage of current or in a furnace, the required temperature being of the order of 1200-1600 C. Preferably, the manufacture of the filaments is carried out before they are mounted within the bulb, to ensure a more uniform temperature during the heating, and the carbon filament forming the core can be coiled or otherwise laid in close loops during the process. Specification 394,557 is referred to.

IPC: B61H13/30
Filed: 1921-05-03
Abstract: 162,674. Chamom, L. E. May 6, 1920, [Convention date]. Force-transmitting mechanism.-To limit the braking pressure to an amount dependent upon the weight of the vehicle, the brake mechanism is arranged to lift the vehicle body in an application and to compress a spring the resistance of which is equal or proportional to the weights of the parts of the vehicle which are not lifted together with the rotational inertia of the wheels and axles if desired. The mechanism shown comprises a floating lever 11 connected by a rod x to the piston of a fluid-pressure cylinder or other actuating means, r. rnd y connected to the brake block of one wheel of a four wheeled bogie, a lever 11<1>connected at z to the brake block of the other wheel and connections between the levers 11, 11<1> including bell cranks 8 and n lever 6. The lever 6 is pivoted at 5 upon the king bolt A the socket member 2 of which is arranged to slide vertically in the guides 1, 3. A spring 13 is interposed between the head of the king bolt which carries the lever 6 and the fixed member 1. When the brakes are applied the lever 6 first turns upon the pivot 5 and when the reaction on this pivot is sufficient, the lever turns on the pivot 6<1> lifting the body and compressing the spring 13. The spring is arranged when compressed to offer a resistance equal to the weight of the bogie and its axles, increased if necessary in order to take into account the rotational inertia of the wheels and. axles. In a modified arrangement, Fig. 3, the members 6, 7, 7<1>, 8 are replaced by members with knife-edge engagement held in contact by a spring 12<1>. The invention may be applied to twoaxle vehicles.

Title: Improvements in and relating to methods of indirectly heating non-conductive materials by electromagnetic induction
IPC: H05B6/46
Filed: 1944-07-04
Abstract: In a method of heating non-conductive material by high-frequency magnetic induction (see Group XI), a thermosetting binder or polymerizable material in liquid or solid form such as phenol-formaldehyde, urea-formaldehyde, alkyd, vinyl or methacrylate resins, or cellulose acetate or nitrate, have associated with them finely-divided magnetic particles having a Curie point within the desired temperature range of heat treatment.  The magnetic particles may comprise Heusler alloy, or an alloy of nickel and chromium, copper, manganese or aluminium, examples of suitable proportions being given.  In an example, phenolic formaldehyde resin glues (available in U.S.A. as "Catabond" No. 400 or 590) were mixed with finely-divided nickel-copper alloy (20 per cent Cu and 80 per cent Ni) in the proportion of 30 per cent metal to 70 per cent glue and the mixture used in gluing wooden articles together.  The particles may also be sprinkled over or impressed into the surface of a film of the plastic, or they may be interposed between two or more such films.ALSO:In a method of heating non-conductive materials by high frequency magnetic fields (see Group XI), adhesive and plastic materials have associated with them a finely divided magnetic substance such as Hensler alloy, or an alloy of nickel and chromium, copper, manganese or aluminium.  Examples are given within the following ranges: (1) Hensler alloy; Mn. 6-26.5 per cent.; Al. 7.2-25 per cent.; Cu. 57.2-80.8 per cent. (2) Cr. 0-5 per cent.; remainder Ni. (3) Cu. 0-30 per cent.; remainder Ni. (4) Mn. 0-15 per cent., remainder Ni. (5) Al. 0-5 per cent.; remainder Ni.ALSO:In a method of heating non-conductive materials by high frequency magnetic fields to predetermined limited temperatures (see Group XI) adhesive and plastic materials have associated with them finely divided particles of iron, cobalt or alloys thereof, or Heusler alloy, or an alloy of nickel and chromium, copper, manganese or aluminium (see Group II). The non-conductive material may be a sodium or calcium silicate adhesive, or a thermosetting or thermoplastic substance (see Group IV) or an adhering mixture containing asbestos, mica or fire-clay. The metal particles may be mixed with plastics adapted to be polymerized, hardened or otherwise cured or shaped upon heating in a mould, the mould being of non-conductive material and having a high frequency work coil placed adjacent to its exterior. In each case metal particles are chosen such that they have a Curie point within the desired temperature range of heat treatment of a given material, heating ceasing when this point is reached.

Title: Improvements in and relating to Glass-blowing Machines.
Inventor: WHITE ALFRED ERNEST
IPC: C03B9/22
Filed: 1916-09-12
Abstract: 111,122. White, A. E., (Westlake European Machine Co.). Sept. 12, 1916. Blowing.-Relates to the type of automatic glass-blowing machine for making electric-lamp bulbs &c. described in Specifications 26222/11 and 26224/11 wherein a series of gathering-mechanisms 55, Fig. 2, carried on a rotating frame successively suck up metal from a furnace into blank moulds 57 and transfer the blanks thus formed to their respectively blowing-spindles, the cycle of operations of each set of moulds and co-operating parts being the same. The blank-piercing plunger 60, Fig. 10, is constructed with a tip 178 of graphite or copper, separate from the body portion to prevent overcooling of the glass. The operating-rod 99, 103 of the plunger is made in two separate sections arranged in alinement similar to the sectional plunger described in Specification 26224/11, and the sections are spring-pressed to obtain an instantaneous action of the plunger. The longitudinal air-passage in the plunger communicates with a transverse duct 182 leading into grooves on the exterior of the plunger. The blowing-spindle is slidably mounted in a yoke 63 which is rotatable in a casting 65 secured to the rotating frame of the machine. When the blank is received by the blowing-spindle from the blankmould, the blank-holder 58 is in its lower position and the pivoted jaws 59 are open, the spindle then having the opposite end up from that shown in Fig. 2. A fork 120 is then rocked away from engagement with a projection 119 on a casing 106, thus allowing springs within the blowing-spindle to close the jaws 59 and to raise the blank-holder 58 so as to grip the blank. The plunger 60 is caused by the action of an arm 134 on a tip 130 to indent the blank. The blowing-spindle is subsequently turned almost to an horizontal position and is caused to rotate about its longitudinal axis, preferably with the admission of air to the blank, the inversion of the spindle to the position shown in Fig. 2 being afterwards completed. The spindle is afterwards oscillated by worm-gearing and under the control of a brake with the blank hanging downwards, and the bulb is finished in the mould 56.
