An example describes the hydrolysis of vinasse at 85 DEG  C., using 15 per cent by weight of solid NaOH based on the weight of vinasse.  Specifications 648,784 and 651,643 are referred to.
Patent GB-1141539-A (GB)
Title: Ribbon or tape and a method of making the same
IPC: D04H3/14
Filed: 1966-06-03
Abstract: 1,141,539. Tape; looms; woven fabrics. J-J. WALTER. 3 June, 1966 [9 June, 1965], No. 24737/66. Headings DIE, D1K, D1R and D1T. A ribbon or tape comprises a sheet of parallel warp threads rovings or cords 1 interconnected on at least one surface by a weft thread roving or cord 2 which extends sinuously from one edge of the sheet to the other and which is firmly connected to the sheet by an adhesive. Each weft comprises a heat-resistant core, e.g. polyester, covered with a thermofusible substance, e.g. polyvinyl chloride which forms the adhesive. The warps can be made of glass fibre. The ribbon is made by supplying a sheet of the parallel warps to a ribbon loom and laying the weft in a sinuously extending relationship on at least one of the two surfaces of the sheet and over the whole width thereof by use of a shuttle. The weft is secured to the warps by the application of heat, e.g. at rollers 11, 12. Preferably only two warp threads 6, 7 at each selvedge of the sheet extend through heddles and are subjected to a shedding motion whilst the material between the selvedges remains constantly parallel and in the same plane. The weft is then bound at the selvedges by the two warps, the shedding of which changes after each passage of the shuttle.

Title: Improvements in or relating to apparatus for removing the outside covering from electric wires and cables
IPC: H02G1/12
Filed: 1948-09-22
Abstract: 641,067. Stripping cables. GENERAL ELECTRIC CO., Ltd., and VICKERS, A. J. Sept. 22, 1948, No. 24808. [Class 36] An apparatus for removing the outer covering from an electric cable comprises a plurality of cutting blades 10, the edges 14 of which are arranged to surround the cable and which can be displaced by relative movement of the cable in one direction to permit the end of the cable to pass between the cutting edges, and which return to a cutting position when the cable is withdrawn. Four segmental knives 10 are mounted on a plate 4, each knife being held against the plate 4 with the cutting edges 14 away from the plate by a spring 11. The cable 9 is threaded through the device from the left-hand side, which tends to push the knives 10 away from the plate 4, thus increasing the diameter of the aperture formed by the edges 14 so that the cable can pass freely therethrough until the end reaches an adjustable stop 24. The other end of the cable is placed in a circumferential groove 21 in wheel 18 and is locked in position by lever 22. The handle 20 is then pulled over, causing the end of the cable to be drawn back through the stripping device. This causes the cutting edges 14 to bite into the cable cover making a circumferential cut and as the cable is further withdrawn the cover is stripped off.
Patent GB-425310-A (GB)
Title: Improvements relating to the photographic recording and reproduction of sound
IPC: G11B7/00
Filed: 1933-09-07
Abstract: 425,310. Optical sound recording and reproducing apparatus. SOUND IMPROVEMENTS, Ltd., 113, St. Vincent Street, Glasgow, and ATTKINS, A. S., Challow, Cross Path, Radlett, Hertfordshire. Sept. 7, 1933, No. 24846. [Class 40 (ii)] A method of photographically making a record of sound wherein the shape of the wave form is recorded without amplitude distortion by the variable-width method or of reproducing from such a record is characterized in that the intensity of the recording or reproducing beam of light is varied in accordance with the amplitude of an envelope of the wave form of the sound by means of a device automatically responsive to variations in the intensity of the alternating current which represents the sound being recorded or reproduced. Fig. 1 shows a system for preparing a photographic sound record of the " simple hump" type on a film 28 in which a light source 2 illuminates a slit 4 through a condenser 6, an image of the slit being formed on the mirror of an oscillograph 10 adapted to vibrate about a vertical axis by the current-carrying loop 12. The light from the slit 4 is reflected from the mirror 10 and is focused by a lens 14 on to a grey wedge 16 which is mounted so that its vertical height can be adjusted at will and the density of which increases gradually from its upper to its lower edge. The wedge is mounted on an arm 18 pivoted at 20 and connected by a link 26 to the middle point of the conductor 22 of a hot-wire movement and having its ends firmly attached to terminals 24. A portion of the alternating current representing the sound is passed through the conductor 22, the position of the wedge 16 being dependent on the strength of this current while the separate alternations of the current will be damped out partly by the inertia of the wedge 16 and arm 18 and partly by the capacity for heat of the conductor 22. The image of the slit 4 formed on the wedge is projected on to the film 28 by a lens 30. A modified system employing a triangular aperture in place of the slit 4 is described, Fig. 5, (not shown), for producing a " double hump " record. Fig. 7 shows a reproducing system designed to eliminate background noise in variable width sound records in which a grey wedge 16 supported by a hot-wire movement as described above is mounted in the path of the reproducing beam of light 27. At a point in the travel of the film in advance of the reproducing point a source of light 31 is arranged to illuminate a slit 33 and an image of this slit is formed by a lens 35 on the film. The light which is passed through the film falls on a photo-electric cell 29, the current through which after amplification at 39 is passed through the conductor 22. If desired, an electromagnetic device may be substituted for the hot-wire movement.
