The unwelded chain 26 is, in one embodiment, Fig. 1, fed up a channel section guide 16 towards the welding position and the welded chain is fed down a similar guide 17, the chain links in the guides being held at 45 degrees to the vertical. With a saddle 1 in a lowered position the chain under tension produced merely by the weight thereof or by wheels 24, 25, is fed so that a link 27 to be welded is positioned over the saddle 1 and then levers 19 are caused to turn the links on each side of the link 27 into a horizontal plane. The saddle 1 is raised by a linkage mechanism to bring the link into a dotted line position 27<SP>1</SP> where upsetting tools 2, 3 and electrodes 4, 5 are applied to the chain link and effect its welding. After welding the saddle is lowered and the electrodes and upsetting tools are removed and the chain is advanced by one link and the process repeated. In a modification, Fig. 5, the link turning levers 19 are omitted but the guides 16, 17 are extended so that the links 31, 32 on each side of the link 27 to be welded bear on surfaces 38<SP>1</SP>, 38 on the ends of the guides which are in a horizontal plane. The chain is under tension and with the two links 31, 32 in a horizontal plane the link 27 is positioned vertically. Additional aligning means comprising triangular projections 33, 33<SP>1</SP> are provided at the guide ends to guide the links.

Title: Improvements in processes for producing chlorine dioxide
IPC: C01B11/02
Filed: 1944-05-05
Abstract: 577,054. Chlorine dioxide. MOOCH DOMSJO AKTIEBOLAG. May 5, 1944, No. 8532. Convention date, June 2, 1943. [Class 1 (ii)] Chlorine dioxide is produced by reacting a gaseous reducing agent with a metal chlorate in an aqueous solution previously acidified by a strong acid (except halogenic acids) so that the acidity of the solution is at least 2-normal. Sufficient strong acid, e.g., 14.5 N sulphuric acid, is added to an aqueous solution of a metal chlorate, at least a 3-molar solution, so that the concentration of free acid is equivalent to at least a 2N but preferably 7 to 8 N solution. Sulphur dioxide, not in excess of 10 per cent. but preferably 5 per cent. by volume, is mixed with an inert gas such as nitrogen or air, and an even flow of the final divided mixture introduced at room temperature, into the acid chlorate solution which is subjected to vigorous stirring. Chlorine dioxide, almost free from chlorine, is evolved during the greater part of the process. The process may be carried out at 10-40‹C., but preferably from 20-25‹C. The residual acid solution may be re-used by evaporating, adding fresh acid if desired. separating the acid sodium sulphate which crystallises on cooling, and adjusting the concentration to the desired value, or the used acid solution may be utilised for acidifying the chlorate solution with or without addition of fresh acid. An example is given. U.S.A. Specification 2,089,913 is referred to.

Title: Apparatus for use in the evaluation of the critical flicker fusion frequency of a person
IPC: A61B5/18
Filed: 1972-02-25
Abstract: 1377563 Flicker fusion apparatus BIVIATOR SA 25 Feb 1972 [5 March 1971] 8772/72 Heading ASK  Apparatus for use in the measurement of the flicker fusion threshold of a person comprises a light source 27 energised by an adjustable-frequency electronic-pulse generator to produce a flickering illumination, and a background or adaptation light source, preferably in the form of a ring of incandescent lamps 26, surrounding the source 27 and energised to produce a subjectively non-flickering illumination, the sources 26, 27 being disposed to display on a plane circular screen 24 the flickering illumination surrounded by the non-flickering illumination without overlap and without a visible boundary zone therebetween. The source 27 may be a fast-response spiral-shaped gas discharge tube and is separated from source 26 in a cylindrical casing 21 by a partition 25 extending from an opal-glass screen 24. The intensity of the two sources is adjustable, the source 27 being energised from a pulse generator (1) via o logic circuit (3) and an amplifier (5), Figures 1, 2 (not shown). The generator (1) gives output pulses at a repetition rate in the range of 100H, to 10KH, and the logic circuit produces an output pulse for every 100 pulses from generator (1) and has means for adjusting the ratio M:N between the pulse-duration and inter-pulse interval of its rectangular output pulses, M and N being integers, the sum of which is 100. Pulses from generator (1) pass to cascaded decode counters (11), (12), Fig. 2, having binary outputs connected to binary-to-digital converters (13), (14) respectively. Converter (13) has outputs 0 and 1 to 9 representing units in repeated cycles of counting 100 pulses from generator (1) and converter (14) has outputs 00 and 10, 20..90 representing tens of these pulses. The outputs 0 and 00 pass via an AND gate (19) to set a flip-flop (20) having its output connected to the amplifier (5). One each of the outputs of converters (13), (14), selected by switches (15), (16) respectively, pass to an "AND" gate (18) which is operative to reset flip-flop (20). The required ratio M:N is chosen by adjusting switches (15), (16). The flicker frequency of source 27 is varied by adjusting the frequency of generator (I) by a control which may have a releasable locking mechanism which, when engaged, allows the control to be adjusted only to decrease the flicker frequency.

Abstract: 580,502. Wireless receivers. STANDARD TELEPHONES & CABLES, Ltd.; and WILLIAMS, H. P. May 11, 1944, No. 9035. [Class 40 (v)] In an aircraft receiver for a combined approach path and glide path system in which a modulated carrier of one frequency provides the azimuth indication and another modulated carrier of a different frequency provides the glide path indication, the two radiations are received on a single antenna and applied to a common frequency changer with a single oscillator to provide two corresponding intermediate frequencies. The intermediate frequencies are applied to a common I.F. amplifier adapted to pass two narrow bands corresponding to the two intermediate frequencies which are chosen so that the higher does not coincide with a harmonic of the lower. The I.F. amplifier comprises two valves V1 and V2, the anode of V1 being coupled to V2 through two transformers T1 and T2, the primaries of the two transformers and the secondaries being connected in series. Tuned circuits corresponding to each of the intermediate frequencies are provided by shunting the windings of the transformers with condensers. The I.F. outputs from V2 are applied to two separate detectors similarly through two tuned transformers T3 and T4. The local oscillator preferably provides a frequency between those of the carriers. Specification 556,079 is referred to.

Title: Improvements in the production of low boiling point oils and other products by the destructive hydrogenation of coals, oils and the like
IPC: C10G1/06
Filed: 1928-03-26
Abstract: 287,855. I. G. Farbenindustrie Akt.- Ges. March. 26, 1927, [Convention date]. Hydrogenation, destructive. -In the destructive hydro.. genation of coal, oils &c. the temperature of the reaction is regulated partly directly by means of substances, e.g. the hydrogenating gas, introduced into the reaction chamber and partly indirectly by means of substances part or all of which take part in the reaction or result therefrom. The indirect transfer may be effected by forming a hot jacket by these substances between the reaction chamber and the wall which bears the pressure. In one method of working the preheated hydrogenating gas is passed into a chamber surrounding the contact chamber and isolated from the outer shell of the reaction apparatus and is subsequently led into the reaction chamber through an electric heating device screened from the reaction chamber. The products of the reaction enter a second chamber arranged concentrically with the reaction chamber or pass through pipes situated in the chamber through which the hydrogenating gas is first passed. In another method only part of the hydrogenating gas is passed into the reaction chamber the remainder being circulated in contact with the reaction products. Preheated hydrogen is admitted through a pipe B in the pressure bearing wall E of a reaction chamber A and flows upwardly through the annular space formed by a spiral partition D and a partition N. Specifications 198,063, 266,311, 279,120; and 282,658, [Class 1 (i), Chemical processes &c.], are referred to.
