Title: Improvements in or relating to self-locking nails
IPC: F16B15/04
Filed: 1945-12-17
Abstract: 605,164. Nails. ELASTIC STOP NUT CORPORATION OF AMERICA. Dec. 17, 1945, Nos. 34102 and 34103. Convention dates, Dec. 15, 1944 and Feb. 16, 1945. [Class 89 (ii)] Self-clinching nails have two adjacent shanks of unequal length connected by sections forming a distortable head of loop-like form and towards the point are provided with interengaging formations that on flattening of the head, resulting from driving home, cause one of the shanks to move laterally away from the axis of the nail. As made from a sheet metal blank, notches 14, 16 and 18, Fig. 1, define bending lines, whereby sections 36a, 36b form the head, the line 32 being displaced laterally from the centre of the notches 18, and that the notches remain on the longer shank portion 34, Fig. 3, and cause the two shank parts to interlock on flattening of the head. A slot 20, preferably of chevron form, produces a projection 22 that interlocks with a stamped formation 26 in the other shank part and causes the end of the part 38, Fig. 5, to bend away from the axis when the shanks have relative movement due to the flattening of the head. The shanks are preferably stamped to form interfitting channel sections. The amount of clinching movement may also be varied by punching the slot 20 at different distances from the end of the shank. In a modified form, clinching is due to a hole 68, Fig. 7, engaged by triangular projections stamped from the edge of the part 52, barbs 70 being advantageously provided on the end of the displacement section of the shanks. Between the triangular projections and the head the sides of the outer channel member guide and retain the upper portion of the inner member. The Specification as open to inspection under Sect. 91 describes the provision of an additional hole between the slot 20 and the end of the shank to enable the displaced end of the shank to crumple when outward movement is difficult, due to the nail being driven into hard material. This subject-matter does not appear in the Specification as accepted.

Filed: 1945-12-20
Abstract: 605,487. Range-finders. KODAK, Ltd. Dec. 20, 1945, No. 34566. Convention date, March 13, 1943. [Class 97 (i)] A coincidence or stereoscopic rangefinder has an auxiliary view-finder optical system, part or all of which is movable into the beam from one of the range-finder view points to produce a reduced image of wider field of view in a comparison plane of the finder to permit the latter to be readily directed on to the object to be ranged. The optical system may be an inverted Galilean telescope diminishing the image from the window, or may include a reflector directing light from an auxiliary objective into the range-finder system. The coincidence finder, shown in Fig. 3, comprises an end reflector 51 and semi-transparent reflector 52, light from which forms images in the plane 55 of an eye-piece by means of objective 53. The Galilean system comprises a negative lens 71 against a beam-accepting window in the case, and a pivoted member 74 carrying a mirror 73 and positive lens 72. The member 74 is rotated into the position shown by lever 80 and spring 77, when the lenses 71, 72 form a reduced image in the plane 53, the image formed from the mirror 51 being still visible. On releasing the lever 80, the member 74 is rotated by a spring 83 out of the beam from the mirror 51. Alternatively, the lenses 71, 72 may be coaxially placed in a holder laterally slidable out of the beam. The mirror 51 is movable to effect coincidence by means of a cam 90 connected to a disc 62 having a spiral coincidence line 63 as described in Specifications 605,485 and 605,486. In the stereoscopic finder, shown in Fig. 10, images are produced in comparison planes 112 by objectives 111. An auxiliary objective 120 of shorter focal length and wider field of view than the objectives 111, forms an image in the adjacent comparison plane by means of mirrors 42, 43, rotated into position by hand-lever 45 and rotated into their inoperative positions by a spring 46. A similar system may be applied to a coincidence finder having two objectives.

Title: Improvements relating to the treatment of cellulosic fabrics
Inventor: HIBBERT GILBERT STANLEY
IPC: D06M13/12
Filed: 1958-10-30
Abstract: In the reaction of cellulosic fabrics with aldehydes the catalysts used comprise mixtures of hydrochloric acid with calcium, magnesium or lithium chloride, of sulphuric acid with sodium chloride and of trichloracetic acid with calcium chloride. Specifications 462,005, 500,184 and 504,916 are referred to.ALSO:The wet crease recovery of fabrics made from cotton, linen or viscose rayon or mixtures thereof, alone or in admixture with non-cellulosic fibres, such as cellulose acetate or "Terylene" (Registered Trade Mark), is improved by treating them with an aqueous solution of an aldehyde in the presence of a catalyst consisting of (1) an acid having a dissociation constant in water at 25 DEG C. of not less than 10-2 and (2) a salt which does not interact chemically with the acid to produce the separation of a gaseous or solid phase and does not have a buffering action in the presence of the acid leading to an increase in pH value and a reduction in the activity of the solution, the concentration of the salt being such that the swelling of the cellulosic material is not appreciably reduced below its swelling in pure water; the fabrics are allowed to lie in the wet condition for a sufficient time to enable the reaction of the cellulose with the aldehyde to take place to the desired extent, whereafter they are washed in water or dilute alkaline solutions to remove excess reactants and dried.  Specified aldehydes are formaldehyde, glyoxal, alphahydroxyadipaldehyde and pyruvic aldehyde.  The acid may be hydrochloric, sulphuric, phosphoric or trichloracetic acid and the salt may be lithium sodium, calcium, magnesium or zinc chloride, sodium bisulphate or sodium or calcium nitrate.  The fabric may be impregnated with the solution, stretched on a frame or tightly wound round a cylindrical roller and left in wet condition at 0 DEG C.-100 DEG C., e.g. at 18 DEG C.-22 DEG C., for 24-48 hours.  The fabric may subsequently be dyed, printed or treated with synthetic thermo-setting resins, e.g. dimethylolurea resins, to improve their dry crease recovery, and mechanically finished, e.g. by embossing, glazing or compressive shrinking.  The Provisional Specifications refer to the use of catalysts comprising as acid, naphthalene sulphonic acid and, as salt, aluminium chloride. Specifications 462,005, 500,184 and 504,916 are referred to.

Abstract: 477,659. Microphones. KOLB, O. K. (Beer, P. F.) Dec. 24, 1936, No. 35373. [Class 40 (iv)] [Also in Group XL] A microphone of electrostatic or eddycurrent type is associated with a valve which acts as a generator of high-frequency oscillations by virtue of its grid-anode capacity. In Fig. 1, the electrostatic microphone M comprises a diaphragm O vibrating opposite a plate K, the condenser thus formed being connected in series with the grid coil L1. The anode circuit is tuned by the coil L2 to a frequency slightly higher than that of the grid coil, and the oscillation amplitude is varied by the microphone. The modulated oscillation is rectified in the valve E and the rectified signal is fed from a transformer T in the anode circuit, the high frequency being byepassed by a condenser C2. The microphone may be connected across the grid coil, Fig. 2 (not shown), or across the anode coil, Fig. 3 (not shown). In Fig. 4 the microphone diaphragm O which may be of aluminium vibrates opposite a closely adjacent flat spiral coil L1 which forms the grid coil. - The coil may be mounted on a plate of insulating material, e.g. powdered iron bonded by a synthetic resin. The tuning and damping of the grid circuit are affected by the varying eddy currents produced in the diaphragm. In Fig. 5, the eddy-current effect is combined with an electrostatic effect, the condenser formed by the diaphragm O and the fixed plate K being connected in series with a condenser C3 between the anode and cathode of the valve E. The valve E, microphone O grid coil L1, adjustable anode coil L2, and output transformer T, may be arranged in a spherical casing B, leads being brought in though an earthed metal tube R. The coils L1, L2 may have cores of powdered iron, and the coil L2 may be tuned by a screw-adjusted iron disc J.
