Title: Improvements in or relating to the manufacture of belting
Inventor: WARREN FREDRICK WILLIAM
IPC: D06M15/244
Filed: 1954-04-10
Abstract: 787,177. Fireproof coated fabrics; laminates. DUNLOP RUBBER CO., Ltd. March 30, 1955 [April 10, 1954], No. 10608/54. Drawings to Specification. Class 140. [Also in Groups IX and XXIV] Belting fabric contains fibres or filaments of cotton, rayon, nylon or polyester and others of a flexible fire-resistant polymer or copolymer of vinyl or vinylidene chloride, so that when one or more layers of the fabric are coated with fireresistant material and subjected to heat and pressure, the fire-resistant fibres or filaments impregnate the other material of the fabric. The fire-resistant and other material may be mixed in the fabric by employing separate yarns of the two materials in the warp and/or weft, by plying such yarns together, or by spinning yarns from a blend; examples described have a " Saran " (Registered Trade Mark) monofil in each constituent ply of cabled yarn. The weave may be single ply or multiply, or consist of layers of weft threads bound together by warp threads that interlace alike. Specification 781,170 is referred to.

Title: Improvements in Clasps.
Inventor: DEHN FRANK BERNHARD
IPC: A41F11/02
Filed: 1916-07-27
Abstract: 105,177. Dehn, F. B., (Plamondon, G.). July 27, 1916. Stocking-suspender grips; clips, pivoted-jaw.- In stocking-suspender clasps of the type comprising a shouldered backed-plate having a togglejointed securing member pivoted to it, the upper arm 14 of the toggle member is adapted to be turned on its pivot to effect the partial opening of the clasp by swinging the suspending loop 18, a spring 37 cut from the backplate 12 then throwing up the toggle member and completing the opening of the clasp. The backplate 12 and arm 14 are pivoted on the inturned ends 22 of the loop 18 by means of sleeve parts 24, 25 respectively, the parts 25 being provided with shoulders 25<a>, Fig. 10, which the side arms 23 of the loop 18 engage, a limited independent movement of the loop being permitted. The spring 37 operates on a lug 33 on the arm 14, the spring bearing on the flat face 35 or 36 of the lug, according as the clasp is in the closed or open position. The wire loop 15 of the toggle member is pivoted in a sleeve 40 formed on the arm 14; the spring side arms 15<b> of the loop being in compression, the loop normally tends to turn on its pivot, owing to the engagement of the side arms with cam-surfaces 41 on the ends of the sleeve, and assume the position shown in Fig. 2, with its concave side towards the base-plate 12. A piece of tape 29 having its end 30 doubled upon itself is placed round the hooded extremity 28 of the plate 12 with which the wire loop 15 engages, a piece of string 29<a> is placed in the fold of the tape, and the hook 28 is then compressed upon the tape. In a modification, the shoulders 25<a> are dispensed with, a projection on one of the inturned ends 22 of the loop co-operating with the arm 14 of the toggle.

Abstract: 526,025. Turning. CONE AUTOMATIC MACHINE CO., Inc. Feb. 3, 1939, No. 10722/40. Convention date, Feb. 4, 1938. Divided out of 528,694. [Class 83 (iii)] In an automatic multiple-spindle workturret lathe, the turret 6 carrying work-spindles 5 carries a Geneva plate 10 co-acting with roller 8 mounted on an arm 7 rotating with the cam shaft 4. The slots 9 of the Geneva plate are inclined to radii thereof, as shown in Fig. 1, so that the roller 8 leaves them in a tangential direction when indexing is complete and. thus stops rotation of the turret before disengagement takes place. Shock is thereby reduced and no indexing bolt is necessary, the locking bolt 15, actuated by a spring 16 and a cam, merely serving to secure the turret against rotation.

Title: Improvements in or relating to the detection and measurement of movement
Inventor: EGELSTAFF PETER ALFRED
IPC: H01S3/08
Filed: 1967-11-10
Abstract: 1,242,063. Detecting particles photoelectrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 7, 1968 [Nov. 10, 1967 and March 5, 1968], Nos. 51371/67 and 10757/68. Heading G1A. [Also in Divisions H3-5] Specification describes method of measuring or detecting the movement 11 of a particle in or relative to a fluid, comprising directing a beam of laser light b at the particle and observing the change in frequency, due to the Doppler effect, of said light scattered or reflected by the particle. As shown the particles comprise milk added to the flowing water to increase its scattering. The laser beam b, passing from laser 12 via beam-splitter 13, reflector 16 and focusing lens 18 is focused on the particles and the scattered light detected, in direction limited by stop 20, by photo-tube 19. A second "reference" beam a passes via neutral density filter 14 behind the water tube 10 and is also detected by the photo-tube 19. The photo-tube has a non-linear characteristic, whereby mixing of the two incident beams takes place and the Doppler beat appears at the output thereof. An absorber 21 absorbs the non scattered part of beam b. The laser beam may be directed along a runway to detect turbulence caused by aircraft, the photodetectors being at the side of the runway, whereby the Doppler beat is produced by self beating within the scattered light using the homodyne effect, or at the far end of the runway whereby beating at the photo-tube takes place as in the illustrated embodiment. The laser beam may be directed along a river, to detect its velocity, the scattered and reference beam being detected by telescopes. The laser beam may be directed at a moving steel strip to detect Doppler shift in the reflected light.

Abstract: 577,371. Shear-blades, punches and dies. HAUT, F. June 5, 1944, No. 10815. [Class 83 (iv)] A press tool, particularly for punching out laminations of high grade sheet metal, has the cutting edges of the punch and die built up of elements of tungsten or tungsten compound inserted in separate pieces into the punch and die body. The invention is described with reference to a punch-and die for stamping out U-shaped blanks. The die comprises a base 1 to which are bolted elements comprising tungsten or tungsten carbide blocks 5 brazed to backing pieces 8. By using standardised sizes of straight and arcuate elements, various forms of dies and punches could be assembled for stamping out various shapes. If a limited space does not allow this method of attaching the cutting elements, the tungsten elements may be brazed directly to the base or body of the punch or die.

The organic phase may also contain an amine anion extractant or where R<11>1, R<11>2 and R<11>3 represent substituted or unsubstituted alkyl, aryl or aralkyl groups. Preferred extractants of the three types are (dibutyl) - butylphosphonate, di - (2 - ethylhexyl)- phosphoric acid and tributyl phosphate respectively. Amines may also be present. Other suitable extractants, and solvents and amines are listed. The Re may be recovered from the organic phase by stripping with water or the Mo and Re may be stripped from the organic phase with NH4OH and the Re may be selectively recovered from the eluate with a quaternary ammonium extractant. The Re values may be selectively extracted by contact with a compound of Formula I before extraction with the solvent containing compounds of Formulµ I and II. The initial aqueous solution is preferably obtained by leaching molybdenite with HNO3. In comparative examples (1,2) DBBP is used alone to extract Re and (5,6) Mo is subsequently extracted with a mixture of DEHPA, TBP and amine.

Title: Improvements in or relating to methods of producing aqueous solutions of carbamide resin pre-condensate
IPC: C08K5/18
Filed: 1953-04-28
Abstract: A plasticizer is suspended in a viscous aqueous solution of a urea- and/or thioureaaldehyde condensate to which aniline, an alkyl aniline, e.g. toluidine, or an alkoxy aniline, e.g. anisidine, has been added.  The suspensions are stable and useful as adhesives, or-mixed with a filler, e.g. cork scrap-as fillers between the inner and outer soles of shoes.  The preferred concentration of plasticizer is 5-25 per cent of the weight of dry resin and 2-6 per cent of amine based on the resin gives optimum stabilization.  In the example, aniline and tricresyl phosphate are added to an aqueous ureaformaldehyde condensate having a viscosity of 1200 centipoises and the mixture is vigorously stirred.  Mixed with cork scrap and citric acid solution as hardener it forms a pliable filling composition for the space between the inner and outer soles of a shoe.
