Title: Improvements in or relating to electric arc atomic hydrogen heating torches
IPC: B23K28/02
Filed: 1934-06-22
Abstract: 439,644. Arc heating torches. GUEST, A. L., Epperstone, Fairy Road, Wrexham, Denbighshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. June 22, 1934, No. 18543. [Class 39 (iii)] An external magnetic field is arranged to pass through the arc loop in an atomic hydrogen torch in the same sense as the magnetic field due to the arc loop itself. In Fig. 1 a single electromagnet 5 is arranged at right angles to the plane of the electrodes 1, 2. In Fig. 2 two pairs 13, 14 and 15, 16 of electromagnets are used, the planes of the two pairs being inclined in different directions to the planes of the electrodes 11, 12. The two pairs' are alternately energized by means of a cormnutator 18 to cause oscillation of the arc. In a modification the commutator 18 is replaced by two rectifiers of the dry plate or discharge tube type connected to the two pairs in opposite senses. In a further modification the circuit containing the rectifiers and electromagnets contain also resistances and reactances and are arranged in parallel with the arc and its limiting reactance. With parallel electrodes, as the tips are consumed, the arc loop moves away from the magnetic field with a consequent increase in are voltage which is utilized to adjust automatically the electrodes. The current for the electromagnet may be derived from a current transformer in series with the arc or in series with a reactance across the supply circuit.

Abstract: 359,947. Synchronous movements. HARRIES, J. H. O., Shirley, Old Road, Frinton-on-Sea. June 18, 1930, No. 18569. [Class 40 (iii).] To keep television scanning mechanism 2 in synchronism with a synchronizing current in an inherently sparkless manner, a continuously variable resistance 20 produces, in a local circuit 10, continuous variations of periodic character synchronously with the movement of the scanning mechanism, and changes in the phase of the variations relative to the synchronizing currents supplied to the local circuit produce variations in the resultant current, which are used to bring the scanning mechanism into synchronism. The arm 18 contacting with the resistance 20 is carried on the shaft 4 driving the scanning-disc. The resultant current in the local circuit controls an electromagnetic brake 5, 6. To frame the television image the resistance 20 is rotated relatively to the contact arm, Fig. 2 (not shown). According to modifications : the variable resistance is in the grid circuit of a pair of thermionic valves, the synchronizing current is applied to the anodes, and the anode current is used to produce the synchronizing effect, Fig. 3 (not shown) ; the synchronizing effect is produced by altering the capacity of a circuit in the output, and tuned to the frequency of an alternator coupled to the scanning apparatus, Fig. 4 (not shown). Specification 357,535 is referred to.

Title: A new or improved method of determining levels or directions normal to an axis and improvements in or connected with surveying instruments, levels and the like
Filed: 1919-07-28
Abstract: 154,958. Barr & Stroud, and French, J. W. July 28, 1919. Sighting - levels. - Comprises an improved method of determining levels or directions normal to an axis, in which the observations from the axis may be made at right-angles thereto in opposite directions simultaneously, together with provision whereby the two lines of sight maintained in axial alinement mav be rotated about the axis and used successively for making comparative observations in the same direction. The instruments are constructed so that an erect image of an object is obtained without the use of an erecting eyepiece and so that the tacheometric angle is reckoned from the vertical axis. Reflectors consisting of prisms are mounted in conjunction with a telescope system so that the optical axis passes throughout the line of intersection of the reflecting surfaces. A prism A with a silvered reflecting surface is arranged with a right-angle prism on its hypotenusal face, reflection of rays entering from the left being reflected from the surface 5 through an aperture 2 in the silvered surface and rays from the right reflected from the silvered surface. The system may be inverted and a horizontal line of sight provided by fitting a reflecting prism at the eyepiece end or the arrangement shown in Fig. 4 provided in order to raise the level of the eyepiece. In modification of the prism system AB the prism B may be a small prism just covering the window 2 or a narrow prism at one side of the prism A, but reflecting the light in the same manner. When arranged as a surveying level, Fig. 10, the instrument comprises a base D supported on levelling screws E, carrying a frame G capable of free rotation round a vertical axis, when the screw is released. The telescope K is mounted in the frame G about the horizontal axis L. Spirit levels N, P are fitted to the frame and telescope respectively. The verticality of the telescope being roughly adjusted by the level N, the line of sight is directed on to the staff and the reading on the cross-wire noted. The telescope is then rotated through 180 degrees and a second reading taken, and the telescope swung on the axis L to the mean of these readings, when the line of sight will be level.

Abstract: 1,114,857. Welding by fusion. K. H. STEIGERWALD. 4 May, 1965 [6 May, 1964], No. 18663/65. Heading B3R. In electron beam or like, e.g. light or laser, welding filler metal in the form of wire, strip, powder or liquid is fed to the seam and is heated adjacent the weld zone by an arc, a second beam, or the same beam as heats the weld zone. In the latter case, the beam is deflected from the weld zone to the filler material or the weld zone and the filler material are heated by different portions of the beam. The filler wire may be transversely oscillated. The filler material is welded to a higher temperature than the weld zone to assist in the transfer of molten metal. An electric field may be set up more positively to transfer the molten metal. The work and the filler material are fed continuously. In one modification, the filler is fed in horizontally and the work is lowered vertically to effect a vertical weld with gravity assisted metal transfer. The method may be used for cladding, for V-groove welding or for parallel-sided gap welding using one or more passes. The filler wire or strip is fed at an acute angle or perpendicularly into the gap and may be fed centrally or into contact with one of the workpieces. When a single beam is used deflected from the weld zone to the filler material, the relative heat inputs may be controlled by intensity duration or focusing. A continuous or pulsed beam may be used. The beam may be oscillated from side-to-side of the gap, and at each end of its oscillation it impinges in part on the filler wire and in part on the work.

Title: Improvements in and relating to the production of phenol formaldehyde condensation products
IPC: C08G8/28
Filed: 1922-07-07
Abstract: In the production of phenol-formaldehyde condensation products, the initial condensation, carried out with a portion only of the total formaldehyde necessary for the complete reaction, is conducted under reduced pressure in the presence of coaltar or mineral oils or both, with or without emulsifying agents such as aromatic sulphonic acids of high molecular weight, sulphonated castor oil or alkali metal salts of the oxyacids obtained by the oxidation of drying oils.  The barium, calcium, or strontium derivatives of phenols may be present as catalysts.  In examples phenol is condensed with formaldehyde in presence of neutral coal-tar oil and barium phenolate, the varnish-like product separated from the watery layer, evaporated, and the remainder of the necessary formaldehyde added, the resin being hardened if desired in moulds or mixed with alcohol for use as a varnish. The initial condensation may be carried out without a catalyst, the latter being introduced prior to the evaporation. Another example shows the condensation of cresylic acid and formaldehyde in presence of coal-tar oil and calcium cresolate as described above, sulphonated castor oil or the potassium salts of the oxyacids obtained by the oxidation of drying oils being added at the commencement of the evaporation.
