Title: Improved method of glueing or uniting the laminae of laminated articles
IPC: B29C65/48
Filed: 1944-04-20
Abstract: Layers of wood, paper, or like material to be laminated together and simultaneously bent or shaped are assembled with intervening layers of a cold-seting synthetic resin adhesive, in a jig or clamp which holds the layers in the required shape, the whole of the exposed perimetrical edge parts of the unset adhesive layers are secured by a short exposure to radiant heat or infra-red rays, and the balance of the adhesive is then allowed to cold harden.  The jig may be removed, after curing the edge portions, and the cold-hardening of the adhesive takes place without the assistance of the jig.  The heating may be by gas-fired, radiant-heat, infra-red panels, which may be arranged to form a tunnel along which the work is conveyed. Alternatively the heating panels may be traversed past the work-piece.  The synthetic resin adhesive may be urea- or phenol-formaldehyde with a hardener or catalyst.  Specification 562,953, [Group VIII], is referred to.

Patent GB-825751-A (GB)
Title: Improvements in and relating to optical bleaching agents
Inventor: FREY RAYMOND
Filed: 1956-03-09
Abstract: The invention comprises compounds of the formula <FORM:0825751/IV (b)/1> where X is H or alkyl, Y is acylamino, monosubstituted ureido or a group <FORM:0825751/IV (b)/2> Z and Z1 are halogen, hydroxy, alkoxy, aryloxy, amino or substituted amino and S and S1 are carboxylic acid or sulphonic acid groups or salts thereof.  The compounds in which Y is acylamino or ureido are obtained from 4-amino-41-nitro-stilbene (containing the groups S, S1 by condensing with cyanuric chloride or bromide, hydrolysing one halogen atom to hydroxyl, condensing the other halogen atom with an amine X-NH-alkylene-O-X, reducing the nitro group to amino and finally reacting with an acid chloride or an isocyanate; they may also be obtained from the analogous 4-amino-41-acyl-amino-stilbene.  The compounds in which Y is triazinylamino are prepared in the same way but using a cyanuric halide for the last stage and replacing the remaining halogen atoms by the appropriate Z and Z1 groups. Alternatively, symmetrical products can be obtained by condensing 4:41-diaminostilbene (containing the groups S, S1) with two mols. of cyanuric chloride or bromide and replacing the remaining halogen atoms in either order by hydrolysis and reaction with X-NH-alkylene-O-X.  The products are obtained as sodium salts and are used as optical bleaching agents.  In examples: (1) 4:41 - diaminostilbene - 2:21 - disulphonic acid is condensed with 2 mols. of cyanuric chloride, one pair of chlorine atoms is hydrolysed to hydroxyl with sodium carbonate and the other pair reacted with two mols. of ethanolamine; (2) as in (1) using b -methoxyethylamine; (3) as in (1) using N-ethyl-ethanolamine; (4) 4-amino-41-nitrostilbene-2:21-disulphonic acid is reacted with cyanuric chloride, one chlorine atom hydrolysed and the other reacted with ethanolamine; the nitro group is then reduced to amino and reacted with phenyl isocyanate; (5) as in (4) until the last step when the amino group is reacted with cyanuric chloride, one chlorine atom hydrolysed and the other reacted with aniline; (6) as in (4) using acetyl chloride for the last step; (7) as in (1) using 4:41-diamino-stilbene - 2:21 - dicarboxylic acid; (8) as in (5) using for the final step sodium o-chlorophenate to introduce an aryloxy group.ALSO:Optical bleaching agents for fibrous materials comprise compounds of the formula <FORM:0825751/IV(c)/1> where X is H or alkyl, Y is acylamino, mono-substituted ureido or a group <FORM:0825751/IV(c)/2> Z and Z1 are halogen, hydroxy, alkoxy, aryloxy, amino or substituted amino and S and S1 are carboxylic acid or sulphonic acid groups or salts thereof.  The compounds can be applied to natural cellulose, e.g. paper, straw and cotton, nylon, regenerated cellulose and light leathers.  In an example cotton is treated with compound where X = H, S = S1 = 2-sulphonic acid, Y = triazinylamino, Z = OH, Z1 = ethanolamino.

Title: Improvements in aircraft controls
IPC: B64C13/02
Filed: 1942-06-01
Abstract: 557,464. Aircraft controls. PHILLIPS & POWIS AIRCRAFT, Ltd., and ROBERTSON, F. H. June 1 1942, No. 7430. [Class 4] An aircraft control column has a control grip movable about an axis at right angles to the column and connected by an adjustable linkage to a control sprocket on the column so that the leverage exerted by the pilot can be varied. A control column 3, movable about a transverse axis to actuate an elevator, carries an arm 12 pivoted about a longitudinal shaft 11 and supporting a control grip 13. A pin 14 on the arm 12 carries a roller 15 engaging a slot 7 in an arm 6 connected to a sprocket 4 by which the ailerons are actuated. The shaft 11 is supported on the column 3 by a screwed shaft 10 passing through spacec lugs 8, 9 between which is mounted a nut 16. By rotating a thumb ring 17 the shaft 10 can be moved axially to displace the shaft 11 from a position in which it is coaxial with the sprocket 4 to a position in which the roller 15 is at the top of the slot 7 so as to reduce the velocity ratio of the sprocket 4 relative to the angular movement of the arm 12. Any substantial rotation of the arm 12 about the axis of the shaft 10 is prevented by the pin 14.

Abstract: 397,221. Phasedifference measurements. KUBALE, J. C. and GENERAL RAILWAY SIGNAL CO., Ltd., 512, Australia House, Strand, London. March 14, 1932, No. 7582. [Class 37.] Currents or pressures of which the phase-difference is to be measured are successively applied . through a mechanical rectifier to a direct-current instrument, and the difference . in the setting of the rectifier brushes to produce maximum or zero effect. on the instrument is'observed. As shown in Fig. 1, the rectifier consists of a two-part commutator 6, driven by a synchronous motor 3, co-operating with four brushes 10, carried by a disc 12, which is mounted on a shaft 13 carrying a pointer 14 movable over a fixed dial 15 by means of which the angular setting of the brushes is indicated. Two opposite brushes 9, 11, Fig. 3, are connected to a galvanometer 23, the other two brushes 8, 10 being connected to tappings on a non-inductive potentiometer resistance consisting of a high-resistance part 18 and a low-resistance part 19. The synchronous motor 3 is driven from a supply 25, 26 of the same frequency as the currents or voltages to be tested. A part or the whole of one of the voltages to be tested is applied to the terminals 20, 21 and the shaft 13 is rotated until the instrument 13 indicates zero or maximum rectified current. The second voltage is then similarly applied and the shaft. 13 again adjusted until the instrument 23 gives the same indication. The difference between the angular settings of the rectifier brushes as indicated on the dial 15 is a measure of the phase displacement between the two voltages. For measuring the phase displacement of a current, the current is applied to the terminals 21, 22. A standard voltage for comparison of phase displacements may be obtained from an auxiliary circuit including a switch 27 and high resistance 28. Specification 382,464 is referred to.
