Title: Improvements in and relating to welding rods
IPC: B23K35/30
Filed: 1935-07-04
Abstract: A welding rod comprises a ferrous metal core containing niobium with a flux coating containing 1-50 per cent of silicon in order to avoid loss of niobium during welding.  Such a rod is used in welding chromium-nickel and chromium steels such as those described respectively in British Specification 414,211 and U.S.A. Specification 1,954,344.  Silicon, ferro-silicon or other silicon alloy may be mixed with slag forming materials such as metallic oxides, silicates, fluorides, borates and/or carbonates and/or a binder such as dextrine, a soluble silicate or silicon ester.  One example of a welding rod for arc-welding may contain 18,39 per cent of Cr, 8,95 per cent of Ni, 0,72 per cent of Nb, 0,17 per cent of Si, and 0,06 per cent C, provided with a coating containing 30 parts of felspar, 10 of lime, 5 of chrome ore, 2 1/4 of dextrine and 2 1/2 of Si, or 75 of Ca-Mg silicate, 10 clay, 10 of rutile, and 5 of 75 per cent ferro-silicon.  Other examples of rods contain 0,01-0,3 per cent C, 0,1-3 per cent Nb, up to 1 per cent each of Si and Mn, together with either 3-30 per cent Cr and up to 5 per cent Ni, or 12-30 per cent Cr. and 5-30 per cent Ni.  The Nb may be up to 5 per cent and not less than 4 times and preferably 8-10 times carbon content.  Up to 4 per cent tantalum may be used.  The flux may in addition be applied to the work as well as to the rod.  The Specification as open to inspection under Sect. 91, also states that "any material which is a strong reducing agent for columbian oxides under welding conditions such as aluminium for example, may be substituted for all or part of the silicon." This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the transmutation of chemical elements
IPC: G21G1/02
Filed: 1934-06-28
Abstract: 630,726. Producing neutrons. SZILARD, L. June 28, 1934, Nos. 19157 and 19721. [Class 39 (i)] A neutron chain reaction generates power and produces radio-active isotopes. The reaction takes place in a mass 3, Fig. 1, comprising indium and beryllium, bromine or uranium. Fast deuterons from a canalray tube 1 bombard a deuterium target 28 to produce initiating neutrons which react with In<115> to produce In<112> and " tetra neutrons " of mass about 4.014. These tetra neutrons react with the Be, Br or U to produce double the number of simple neutrons, thereby providing a chain reaction. Emerging neutrons transmute a layer 9 to produce radio-active substances. Alternatively, Fig. 3, the initiating neutrons may be produced by passing cathode-rays through a sheet 402 of Pb or U to generate hard X-rays which react with beryllium in the mass 3 (or an inner mass 407) to yield neutrons. The critical thickness of the layer 3 for a self-sustaining chain reaction is stated to be of the order of 50 cms. Tetra neutrons are stated to be produced when neutrons of 100,000 e.v. to 8 m.e.v. energy react with the In<115>. Power is obtained by heat exchange from water or mercury passing through cooling tubes 107, 110, 111. Other methods of obtaining the initiating neutrons are described in Specification 440,023.

Abstract: 980, 373. Nuclear power plant. ESSO RESEARCH & ENGINEERING CO. May 17, 1963 [July 16, 1962], No.19810/63. Drawings to Specification. Heading G6C. In a nuclear reactor power plant, benzene is circulated through the reactor as a moderatecoolant. The benzene is supplied to the reactor as a liquid at a pressure above the critical valve and is heated to above the critical temperature inside the core. In one embodiment; the benzene vapour passes directly into a turbine while in an alternative form it circulates through a heat exchanger where it generates steam for a turbine. The thermodynamic characteristics of benzene are such that in the turbine, expansion causes superheating and thus prevents condensation.

[Class 39 (i)] [Also in Group XXXVII] The method of starting a discharge lamp consisting in including in series with it a choke which also acts as an electromagnet to operate a switch which breaks a heating-circuit for the electrodes including the choke is applied to lamps in which the electrodes are connected in series so as to be both heated for starting by the current, this necessitates enclosing the switch in an envelope which does not contain air, it may be exhausted or contain oil or a'neutral gas. The invention is especially applicable to lamps of 1 metre and over in length. The switch may comprise a loose bar forming the armature of the choke magnet and bridging two mercury contacts or the armature may be carried on a leaf spring which carries or operates the contact. Fig. 5 shows an arrangement of the latter sort with provision for slight delay in the separation of the contacts. The armature 17 is mounted on a leaf spring 40 carrying a hook 19 arranged to engage a wire 22 after the armature has moved a certain distance.

Title: Improvements relating to ball point pens
IPC: B43K7/08
Filed: 1954-07-02
Abstract: 772,744. Reservoir pens. HENRIKSEN, E. J. J. July 2, 1954 [July 6, 1953], No. 19500/54. Class 146(3). In a ball-point pen having in the ink reservoir a sliding seal which rests on and follows the end of the ink column as the ink is consumed, the seal consists of two or more layers of different compositions which may be of liquid, semi-liquid or pasty material, the layer adjacent the ink being substantially immiscible both with the ink and with the adjoining layer, and the outermost layer being such that it is unable to flow out of the reservoir. As shown, the ink column 5 is of length B, the seal of effective length E and consisting of two layers 7, 7a, and the reservoir 4 comprises a tube of transparent material formed with a flange 11 intermediate its ends. Two opaque barrel portions 12, 13 are secured e.g. by screwthreads, over the reservoir to abut the flange 11, and the writing tip 2 is fitted within one end of the reservoir 4. The lower seal layer 7 may consist of a solution of gum-tragacanth or gelatine in water, and the upper layer 7a may consist of a mineral oil base grease which protects the gelatine &c. from drying out. The layer 7 could be a thin layer of more expensive material such as silicone grease : it could also be a mineral oil base grease or paraffin oil thickened with metallic soap such as aluminium stearate. The transparent flange 11 is arranged a small distance above the end of the ink column 5 of a completely charged reservoir, and the length E of the seal is made equal to the length B of the column 5, which is the length above the rear end of the tip 2, so that the upper end 8 of the seal will be visible through the flange 11 when the ink is nearly exhausted. The layer 7a could be of a conspicuous colour. In a modification, a transparent barrel constitutes the reservoir, and a mark on the barrel is placed just above the end of the ink column to indicate that the ink is nearly exhausted when the top end of the seal reaches that mark. To avoid air bubbles when inserting the seal into the reservoir, the seal may be formed in rod or tablet form and hard-frozen. It is then inserted, and will melt and expand to contact the wall of the reservoir when it reaches normal temperature. Specification 669,973 is referred to.
