Title: Improvements in or relating to indicator devices
IPC: G09F9/40
Filed: 1958-06-10
Abstract: 835,527. Indicators for electric signalling systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 10, 1958 [June 13, 1957; July 30, 1957], No. 18525/58. Class 40 (1). In an indicator of the kind in which signs are provided on transparencies to be displayed by igniting lamps placed behind them, a number of partial reflectors are provided which permit one sign to be seen by reflection and others by transparency. The lamps are disposed in two rows 7, 8, Fig. 1, in the upper section of block 1, two rows 9, 10 in the lower section and a row 11 in the middle of the block. Each lamp has a separate bore and co-operates with a transparency arranged in five rows, two at 14 on the upper surface of slots 12, two at 15 on the lower surface and one at 16 at the rear. The signs are numerals and are arranged as shown in Fig. 3, each pair. of columns containing all the numerals 0-9, so that by igniting one lamp in each pair of columns the required numerals can be illuminated. The partial reflectors are formed on the surfaces of prisms 21-27 and are. arranged at right angles. If a lamp in row 8 is ignited the image of the corresponding transparency (showing numerals "1" or " 8 ") is reflected by surface 18 and is visible at the viewing window. If a lamp in row 7 is ignited the image of the corresponding transparency (numerals " 0 " or " 9 ") reflected from surface 20, passes through prisms 21-25 and is visible at the viewing window. A lamp in row 11 selects a " 4 " or a " 5," the image passing through all the prisms to be visible at the viewing window. Lamps in rows 9 and 10 present their numerals in a similar way. By selecting lamps a multidigit number can be displayed as shown in Fig. 4. This is achieved by igniting lamp a in row 9, lamp d in row 11, lamp f in row 7 and lamp g in row 8. As shown in Fig. 2 the unit 13 which carries all the transparencies can slide in slot 12 a distance equal to the spacing of adjacent lamps. The numerals are so arranged in pairs, as shown in Fig. 3, that in each pair one numeral is the nine-complement of the other. When unit 13 is displaced, the complementary numeral replaces the numeral previously displayed, so that instead of indicating a number such as " 3591 " (Fig. 4) the nines-complement " 6408 " is displayed. The unit 13 is displaced to read out the nines-complement by energization of a magnet 31 connected to unit 13 by lever 33. Instead of prisms semi-reflecting films may be provided along the lines of the surfaces 17, 18, 19, 20 for the same purpose.

Abstract: 1525433 Adhesion promoting additive for coatings GILLETTE CO 18 April 1977 [6 May 1976] 18652/76 Heading B2E Substrates of alumina, quartz, tungsten, titanium or tantalum are coated with a dispersion of a polyfluorocarbon containing a bis-(chloroalkyl) vinyl phosphonate in which the alkylene groups have up to 4 C atoms, dried and sintered. The additive improves the adhesion of the fluorocarbon to the substrate.

Title: Improvements in or relating to rotary tool heads
Inventor: EMPSON KENNETH GEORGE
IPC: B23B29/034
Filed: 1958-06-11
Abstract: 844,913. Rotary tool heads. SWINDON TOOL CO. Ltd. Feb. 12, 1959 [June 11, 1958], No. 18689/58. Class 83 (3). In a rotary tool head for facing, boring &c., the tool slide is radially fed by a closed-circuit hydraulic system within the head, the rate of flow of the fluid being controlled to regulate the speed of the feed, and the extent of the feed being controlled by an adjustable stop. A bore 7 in the cylindrical body 1, Fig. 3, is connected to a bore 5 in the tool slide 3 by passages 10- 12. With a manually operated valve 14 closed, oil is introduced into bore 7 through passage 10, which is then plugged at 13, the piston 8 being thereby moved to the left to compress the spring 9. When the valve 14 is opened, the spring 9 moves the piston 8 to the right in Fig. 3, and forces the oil into the bore 5, thus moving the tool slide 3 radially outwards. The knob 15 of valve 14 is graduated to predetermine the feed rate of the slide 3. The slide is returned to its central position by a manually rotated pinion 17, Fig. 1, co-operating with a rack 18 on the slide 3. To limit the outward feed of the tool slide 3, the stroke of the piston 8 is adjusted by rotating a graduated head 26 on a sleeve 21 having slots 22 engaging lugs 23 on a nut 24, screwing on a stem 25 of the piston, this nut engaging a collar 27 on the sleeve to prevent further movement of the piston. A by-pass valve 20a between the bores 5, 7 relieves the pressure in bore 5 when the slide 3 is moved by the rack and pinion.

Title: Improved process for the chemical retting of lengths of vegetable fibres
IPC: D01C1/02
Filed: 1951-08-09
Abstract: Lengths of vegetable textile fibres, such as ramie, flax, hemp, jute, urena, ambary and asclepias, are subjected to a chemical setting process which comprises a first treatment with an aqueous solution of an alkali containing an amine salt of palmitic acid as an emulsifying agent and a subsequent treatment with an aqueous solution containing the same substances as in the first treatment and in addition an oxidizing agent.  Preferably the materials are immersed successively in two separate treating baths.  The alkali used may be caustic soda or potash and the amine palmitate may be derived from a primary, secondary, or tertiary amine or from a quaternary ammonium base, e.g. propanolamine, morpholine or tetramethyl ammonium hydroxide.  The oxidizing agent may be hydrogen peroxide or sodium peroxide, or a perborate or other per-salt.  The treatment is effected on green-scutched lengths, i.e. lengths freed from the ligneous parts of the stem. Preferably the material is washed between the two chemical treatments.  The alkali may be present in a concentration of 0.5-2 per cent. and the concentration of the amine palmitate may be 0.5-5 per cent. by weight of the solution.  Each of the two treatments may be effected at 80-100 DEG C. for 20-60 minutes.  After the second treatment the fibres may be washed in water, dried, flexed, and submitted to further treatment, e.g. a mechanical de-gumming treatment by passing them between fluted rollers.
