Patent GB-1271990-A (GB)
Title: Method of measuring a dimension, such as a width
IPC: G01B11/04
Filed: 1969-04-23
Abstract: 1,271,990. Measuring strip width. CENTRE NATIONAL DE RECHERCHES METALLURGIQUES. April 23, 1969 [April 26, 1968], No.20672/69. Headings G1A and G1M. A product 1 such as hot rolled strip whose width 'W' is to be measured is observed by fixed but adjustable optical sighting devices 4, 5, which receive rays emitted from or reflected by 1 and reflect them by means of mirrors 10, 11, lenses 12, 13 and prism 14 on to the surface of a television camera 15. Thus a ray 16 corresponding to one edge 17 will be represented on 15 by a line 17<SP>1</SP>, and similarly for the edge 21 of the product there is a second line 21<SP>1</SP> so that the lighter area 19 corresponds to the visible part of the product viewed from device 5 and the darker area 20 corresponds to the support 3. The distance between the lines 17' and 21<SP>1</SP> is related to the width of the product and may be measured by timing electronic scanning between them and calculating the width by means 24. A line 18 parallel to and directly below the prism 14 will appear on the screen as two spaced apart lines 18<SP>1</SP> and 18<SP>11</SP> and these may be made to coincide with the edges of the scanner. If the product is obliquely placed relative to the devices 4, 5 then the screen 15 gives an image as in Fig. 3, so that the width 'W' may be calculated, from the known distance between scanning lines 25 and 26 and by determining the distances l, m, and n, by measuring the time taken to scan along the lines 29, 30, 31.

Convention date, Oct. 30, 1930. [Class 38 (i).] A stop joint for oil-filled cables is built up in the factory, the prepared cable ends being inserted into the sealed casing without disturbing the coupling or its insulation. The coupling comprises a pair of caps 10, Fig. 3, connected by flexible strips 12 and mounted on insulators 4 each cemented to a head 6 that closes the end of the casing 2. The joint is surrounded by a shield 14 connected by a wire 15 to one of the caps 10 and enclosed by paper insulation 16 with silk thread binding, a body of paper tape 17, and a covering of wide impregnated paper 18.

Filed: 1943-12-14
Abstract: 573,640. Tool bags. RODGER, R. Des. 14, 1943, No. 20942. [Classes 18 and 133] [Also in Groups XXV and XXXI] A tool bag 1, which locks automatically on closing the cover 3, is constructed wholly of metal and the cover 3, which is adapted when closed to secure any external pockets 7, carries an external spring-controlled member 18 or 23, connected operatively to internal retaining elements 16 and adapted after being unlocked to be depressed to impart angular movement to the elements to disengage them and permit the cover to be opened. As shown in Figs. 1 and 5. the member 18 constitutes the handle and is connected at each end to a plunger 13 connected by a stem 15 with a pivoted latch 16 adapted to engage cranked portions 9 of a fixed metal frame 8. On rotating a member 41 by means of a key (38, not shown) so as to bring V-shaped projections 42 into register with V-shaped notches 40, the handle can be depressed against the action of springs 14 to release the latches 16 and enable the bag to be opened. On closing the cover, the latches 16 automatically engage the cranked portions 9, the member 41 being then returned into the locking position by removing the key. The body may be divided by a longitudinal partition and clipped to the frame 8. In the cycle tool bag shown in Fig. 4, the frame 8 is formed with a single-cranked portion and the latch 16 is operated by the key controlled knob 23. The bag is attached to a cycle by a spring 28 secured to U-links 29, 30, bolted respectively to the frame 33, and a bracket 34 clamped to the back stays 35.

Title: A process for preparing textile fibres from rags containing artificial silk
IPC: D06M16/00
Filed: 1930-07-11
Abstract: Textile fibres are obtained from rags containing artificial silk by subjecting the rags, preferably disinfected with a dilute solution of hydrogen peroxide and sorted, to treatment in a bath containing dilute sodium carbonate, removing excess liquid by pressing, treating in a bath containing sodium acetate, pressing again, washing with water, removing the water by pressing and drying, and mechanically disintegrating to a fibrous mass.  In an example the rags are treated for 10 mins. in a 0,4 per cent sodium carbonate solution at about 45 DEG  C., pressed, treated for 10 mins. in a liquid containing equal proportions, e.g. 1 per cent, by weight of sodium hydroxide and acetic acid, pressed again, washed with water, pressed, dried to a water content of about 25 per cent, and disintegrated mechanically in the usual openers.  A treatment with a dilute solution of s water soluble oil, e.g. a 1 per cent solution of sulphonated castor oil, may precede the mechanical disintegration.  The fibres are finally prepared in known manner for carding, spinning, &c.  Coloured artificial silk materials may be treated without affecting the colours.  The Specification as open to inspection under Sect. 91 (3)(a) comprises also a treatment in some cases in a bath of dilute sodium nitrate to follow the treatment with sodium acetate.  This subject-matter does not appear in the Specification as accepted.
