Title: Improvements in or relating to methods of printing from photographic sound, or soundand picture negatives
IPC: G03C5/14
Filed: 1931-10-02
Abstract: 389,161. Sound-films. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin.. Oct. 2, 1931, No. 27470. Convention date, Oct. 29, 1930. [Class 40 (ii).] To obtain correct contrast in printing from. photographic sound or sound picture negatives,. the negative picture is coloured, e.g. by toning or dye-toning, and is printed upon positive material of suitable colour sensitivity by means of printing light of appropriate colour. The process may be employed to obtain uniform correction throughout a film or for correcting- variations in contrast in a given film strip. A red-coloured negative may be printed with. light from a mercury vapour lamp to obtain a strong contrast effect. White light may be used with suitable colour filters or colour wedges ; these may be combined with grey discs or wedges so that on changing the colour of the printing light at different portions of the film, the time of exposure is maintained uniform. Changes in colour of printing-light from white to reddish-yellow may be obtained by the use of an incandescent lamp through adjustment of the voltage. In an example, a film bearing latent sound and picture records is so developed that the correct degree of contrast is obtained in the picture record which is then printed with light of constant intensity ; the negative sound record is coloured red and isprinted on to ordinary, blue-sensitive positive material with light ranging, e.g. from green to yellow and which is varied to compensate for the variation of gamma in the negative and so as to yield a positive of uniform, predetermined gamma.

Patent GB-479965-A (GB)
Title: Improved process for removing the size from sized textile fabrics
IPC: D06L1/14
Filed: 1936-10-13
Abstract: In a process for removing size from sized textile fabrics, a bath is used containing a small amount of persulphate, e.g. 0,2--2 grams/litre.  In addition to the persulphate, percarbonates, perphosphates, perborates, or peroxides may be added to the bath. The process may be used for fabrics of vegetable, animal or artificial materials, and the bath may be acid, alkaline or neutral. Baths containing persulphate and 2--10 grams/litre caustic alkali are particularly useful for cotton fabric, at temperatures up to boiling point if desired.  At temperatures above 80 DEG  C. lower concentration of alkali, e.g. 1 gram NaOH or 2,3 grams of soda/litre may be used.  For coloured, striped or bordered materials, small quantities of hydrogen peroxide should be added to the bath.  Used boiling or bleaching baths may be employed for the treatment, persulphate and alkali if necessary being added in the required amount.  The baths used for desizing may also in some cases be used immediately after for the boiling or scalding treatment.  The persulphate containing bath may also act simultaneously as a bucking, bleaching or other bath. Weakly alkaline, neutral or acid baths are particularly suitable for fabrics containing animal fibres or for coloured, striped or bordered materials, or for nappy materials, e.g. velvet or flannel.  Weakly alkaline persulphate baths may contain NaOH in small quantities and/or carbonates, tertiary phosphates, pyrophosphates, metaphosphates or borates having weakly alkaline reaction.  Such baths and baths containing only persulphate initially may become neutral or acid during treatment.  The treatment may be carried out by steeping the goods in vats or circulation apparatus, kettles, jigs, or on the reel or clapot. The goods, especially singed or closely woven goods should be wetted before desizing with hot water, or hot baths containing wetting agents.  Or wetting agents may be added to the desizing bath.  In an example, cotton piece goods are treated in an impregnating machine with a bath containing per 1000 litres of bath, 10 litres of NaOH (40 DEG  B<\>ae.) and 2 kgs. sodium persulphate at 80--90 DEG  C.  The goods pass through the bath at about 100 metres/minute.  After resting some hours, they pass through a washer into a kettle.  Subsequent bucking yields a product free from stains.  In a second example, coloured, striped or bordered materials of American cotton are treated with a bath containing caustic soda, potassium persulphate and hydrogen peroxide, and are subsequently bleached with an oxygen bath.  Other examples are given in the Specification.

Title: Improvements in scraper blade devices, especially for centrifugal strainer separators
IPC: B04B11/08
Filed: 1956-09-12
Abstract: 797,410. Centrifugal strainer separators. OFFICINE MECCANICHE E. FONDERIE A. BOSCO SOC. PER AZIONI. Sept. 12, 1956 [Oct. 19, 1955], No. 27858/66. Class 46. A scraper device for a centrifugal strainer separator comprises a blade or scraper extending throughout the inner contour of the basket to scrape simultaneously the whole height of the centrifuged material, the blade having a single manually or power controlled rocking movement, in a vertical plane parallel to the axis of the separator, which brings it in sequence to operative positions inside the basket, these positions being determined by the feeding of the blade into the centrifuged material. An arm 24 carries a scraper blade 21 having a length equal to the depth of the strainer basket 7 and shaped to direct the loosened centrifuged material towards the bottom 5 of the basket, the arm being secured to a lug 25 rockable about a pivot 20 mounted on supports 17 secured to a casing 9 around the basket 7. A lid 13, in two interlinked parts, closes the casing when centrifuging is in process. Ears 28 secure the lug 25 through a pivot 33 with the rod 35 of a piston 36 working in a pneumatic cylinder 37, the outer chamber of the cylinder being always open to compressed air in a reservoir 40. When the compressed air is admitted through a cock 41 to the underside of the piston, the piston rises and turns the scraper 21 from the position I to the operative position II provided the pressure air has displaced a stop 50 secured to a spring pressed piston in a cylinder 19 out of the path of the ears 28. The pressure air may also actuate a switch on the driving motor to ensure that the motor is running at a slow speed when the blade enters the basket. The casing covers 13 and similar covers at the bottom of the casing may also be safeguarded in the same way. Near the end of the approach to the operative position, a piston rod 30 forming part of a damping device 29 engages the casing 9 to ease the movement of the blade and a roller 26 on the blade shaft 24 engages the rim of the casing to prevent the blade from contracting the basket. The damper 29 may be incorporated in actuating cylinder by making the piston rod thereof hollow.

Patent GB-1001689-A (GB)
Title: Process for the production of a rabies vaccine
IPC: A61K39/205
Filed: 1963-07-15
Abstract: Vaccines of live rabies virus are produced by culturing chick-or chick eggadapted rabies virus in a growth medium containing chick embryo cells and subsequently harvesting the virus, at least the last propagation step being carried out while the chick embryo cells are maintained in a synthetic protein-free maintenance medium, e.g. Medium 199, Healy's synthetic medium No. 858 or Eagle's basal medium. It is essential that the rabies virus employed in the last propagation step should be subjected to one or more dilution passages in a chick embryo culture in a synthetic protein free maintenance medium.  Trypsinized chick embryo cells were cultured in a growth medium, e.g. solution of lactalbumin hydrolysate in Earle's basic salt solution fortified with animal serum and containing antibiotics at 35 DEG C. for 1 to 2 days.  The growth medium was decanted from the cell sheets which were washed with a synthetic maintenance medium, e.g.  Medium 199, and inoculated with the Flury strain of rabies virus which had been subjected to 138 successive passages by intracerebral inoculation in chicks followed by 64 passages in embryonated eggs. Medium 199 was added and the cells were cultured seven days at 35 DEG C.  The culture medium was frozen and thawed to release intracellular virus and the resulting mixture was centrifuged to separate cell debris.  The supernatant liquid was used to inoculate fresh tubes of culture tissue and the whole process repeated for 14 passages.  Ten limiting-dilution purification passages were then made using physiological saline solution.  To harvest the virus, the liquid is separated from the tissue culture. The residue is treated with a conventional virus vaccine stabilizer e.g. casein hydrolysate, an amino acid sugar mixture or a buffered sugar solution, frozen and thawed to rupture the tissue cells and release the virus.  The stabilizer liquid is decanted, pooled with the prior harvest of maintenance medium and centrifuged to remove cell debris and produce the vaccine. Temperature at propagation is 34 to 37 DEG C. and duration 4 to 14 days preferably 7 to 9 days.
