Title: Method for welding a cover plate to a component part combined from strips of any shape
IPC: B23K15/00
Filed: 1959-09-30
Abstract: 870,537. Control of welding by radiation. ZEISS-STIFTUNG, CARL, [trading as ZEISS, C. [Firm of] ]. Sept. 30, 1959 [Oct. 2, 1958], No. 33245/59. Class 40(3) [Also in Groups XXII and XXXV] In apparatus for welding a cover-plate to an assembly of strips, the strips are located by means of radiation to which the cover-plate is at least partly transparent. The rigidly connected X-ray source 18 and receiver 25 are traversed from right to left by motor 22 to scan the assembly of strips 13 and cover-plate 12. Attenuation of X-rays due to a strip gives a pulse which triggers a pulse generator 28 to initiate an electron beam 4 for welding. Motor 22 supplies a signal dependent upon the scanner position to coils 9 to keep the point of impact of the beam a fixed distance from the X-ray beam and a signal dependent upon its speed to control a delay 27 such as a magnetic tape or memory tube. In modifications the scanner may be stationary and the workpiece traversed. In this form, the electron beam, reduced in intensity may excite secondary X-rays on impact with the workpiece, eliminating the need for an X-ray tube. The receiver may be of a two cell type giving a directive signal to control a servo system keeping it moving along a strip. The X-ray source may be replaced by a radioactive coating on at least part of the strip assembly.

Title: Improvements in felt-proofing and shrinkproofing wool and textiles containing wool
Inventor: MERTENS HEINRICH
IPC: D06M13/364
Filed: 1960-09-28
Abstract: Wool and wool-containing textiles are felt-proofed and shrink-proofed by impregnating them with a dispersion or solution of one or more polymers having molecular weights of at least 10,000 containing acid amide, urea or urethane groups, squeezing, possibly drying and then treating them with dichlorcyanuric acid and/or trichlorcyanuric acid as oxidising agents in aqueous solution or suspension.  The polymers may be of natural origin or synthetically produced, e.g. polyamides such as copolyamides or polyamides derived from caprolactam, capryliclactam and hexamethylene diamine adipate, polypeptides, proteins, polyurethanes such as polyurethanes formed from polymethylolbutane-dioldiisocyanate condensates, polyureas, polyacrylamides, such as copolymers of acrylamide and methacrylamide, polysulphonic acid amides, polyvinyl pyrrolidone, and ureaformaldehyde reaction products.  The wool may be subjected to a mild alkaline pretreatment, e.g. with an N/10 soda solution (liquor ratio 20 : 1 to 30 : 1) at 45 DEG C. for 1-2 hours. and then impregnated with the solution of dispersion of the polymer, squeezed and if desired dried.  The wool may then be formalised moist or dry, e.g. using an aqueous liquor (liquor ratio 15 : 1 to 25 : 1) buffered to a pH of 5-7 containing 2% by weight of formaldehyde at 60 DEG -70 DEG C. for 1 1/2 -2 hours, and washed and is then treated with the aqueous solution or suspension of the oxidising agent which may be acid, neutral, or alkaline at room temperature or increased temperature, e.g. 20 DEG -40 DEG C.  The treatment bath may contain dichlorcyanuric acid and/or trichlorcyanuric acid in an amount corresponding to 2-5% of active chlorine with reference to the weight of goods being treated and may also contain other oxidising agents, e.g. potassium permanganate, monopersulphuric acid and dipersulphuric acid and their salts, peracetic acid and perbenzoic acid, inorganic salts, e.g. calcium chloride, borax, magnesium sulphate and zinc sulphate, and/or organic salts, e.g. the alkali and alkaline earth metal salts of acetic acid and ethylene diamino tetracetic acid, and wetting agents.  The wool may subsequently be subjected to a reductive or oxidative dechlorination bath, with, for example, an alkali metal bisulphite or dithionite, a salt of a hydroxy alkane sulphinic acid or a reaction product of such an acid with ammonia or hydrogen peroxide.  Specification 891,217 is referred to.

Abstract: 416,909. Converting ; automatic regulation. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitõts-Ges. ; 2, Friedrich Karl-Ufer, Berlin.) Nov. 28, 1932, No. 33665. Addition to 386,976. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 27, 1933]. [Classes 38 (ii) and 38 (iv).] An arrangement for controlling electric current comprises two groups of grid-controlled discharge vessels. In Fig. 1 the discharge vessel 1<1> of one group is controlled by a grid voltage composed of a variable direct current voltage 3 applied across a resistance 4, a constant D.C. potential 5<1> and an alternating current voltage 2<1> of constant amplitude and phase. The discharge vessel 1<11> is controlled by the D.C. voltage 3 and a constant D.C. potential 5<11> and A.C. potential 2<11>. The D.C. voltages 3, 5<1>, 5<11> may be given such a value that no current flows in the discharge vessels 1<1>, 1<11>. Upon lowering the variable D.C. voltage 3, the control grids of 1<1> and 1<11> are made more negative and more positive respectively and the latter may then pass current. Similarly, raising of the voltage 3 prevents current flowing in discharge vessel 1<11> and permits current to flow in discharge vessel 11. In Fig. 2 the value, direction and duration of the current in a consumer 10 is controlled through the two groups of discharge vessels 8<1>,8<11> and 9<1>, 9<11>. The discharge vessels 81, 8<11> are directly controlled by the variable D.C. voltage 3 as in Fig. 1. The discharge vessels 91, 9<11> are controlled by the aid of auxiliary discharge vessels 11<1>, 11<11> controlled in the same manner as vessels 8<1>, 8<11> but with reversed sign. The sudden flow of current in 111, 11<11> applies an A.C. voltage of peaked wave form through the transformers 131, 13<11> to the grids of the discharge vessels 9<1>, 9<11>. The current in the consumer 10 could for example be applied for the automatic regulation of a direct current generator from which the direct current voltage 3 is derived.

In a monochrome cathode ray circuit, preferably using an oscilloscope, having a port deflection acceleration grid 3, Fig. 1, adjacent to the fluorescent screen 4 and negative with respect thereto; a grid 5 at a lower potential than the grid 3 is provided between grid 3 and the screen, the spacing between the two grids being less than the spacing of grid 5 from the target, the arrangement being such that secondaries emitted by the grids cannot reach the screen. Secondaries emitted by grid 3 will return to grid 3 due to the lower potential of grid 5 (Vs=1000, V 3 =1500, V 4 =11500) which secondaries emitted by 5 go to closely adjacent grid 3 rather than to the preferably more distant screen (d 3-5  L3 mm. d 5-4 =10-20 mm.). If the grid wires of the two grids are parallel to but transversely offset from one another a moire or watered silk effect is produced on the screen. To avoid this the grid wires of the two grids are inclined at 45 degrees, Fig. 3 (not shown). Alternatively the grids 3, 5 may be formed as coatings on opposite sides of a perforated insulating plate. Port accelerating grid 3 is connected to wall coating 2 and the screen has a film of aluminium, to which the potential of 11500 volts is applied.

Abstract: 430,802. Removing ice from aircraft. UNITED AIR LINES, Inc., 221, North La Salle Street, Chicago, U.S.A.-(Assignees of Hiscock, T.) Nov. 27, 1934, No. 34062. Convention date, Nov. 28, 1933. [Class 4] Ice is removed from a structure, such as an aeroplane wing, by reciprocating a flexible covering over the leading edge of the structure. As shown, a flexible covering 16 is reciprocated over the leading edge of an aeroplane wing by means of a reversible electric motor 18 driving, through a worm and worm-wheel, drums around which pass cords 24 secured to the edges of the covering. The motor is automatically reversed by the engagement of one or other of pins 34, 36 on a pinion 32 driven from a pinion 30 and which engage with a contact lever 38 of a toggle reversing switch. The covering is made of, e.g. textile or woven wire cloth, the outer surface being made water repellant by the application of lacquer and a low freezing point lubricant such as talc powder, graphite or castor oil is introduced between the covering and the wing surface. The edges of the covering are strengthened by sticks 26 and the covering 16 may form the only wing covering.
