Title: Improvements in or relating to the insolubilising treatment of films, filaments, fibres and like shaped articles made from protein solutions
IPC: D01F4/00
Filed: 1946-01-07
Abstract: Filaments, fibres, films and similar shaped articles, made from colloidal solutions of denatured vegetable globulins or casein in aqueous media by coagulation in alkali metal sulphate solutions acidified with sulphuric acid, are rendered more resistant to attack by boiling water or hot dilute acids by treating for a relatively long time the shaped, coagulated, but still water-soluble or dilute salt-soluble articles with an aqueous solution which is free from trivalent metal ions but contains 3 to 4 mols. per litre of sodium or ammonium sulphate, formaldehyde in excess over the up-take of the articles, and has a pH value less than 0.5, attained by the inclusion of sulphuric acid of concentration not less than 200 grams per litre, but preferably less than 320 grams per litre.  The treatment is continued until the articles become resistant to treatment for 90 minutes at 97 DEG  C. in a testing bath containing 0.1 per cent sulphuric acid and 0.25 per cent sodium sulphate.  The treatment may be effected at 30-40 DEG  C. and may extend over a period of 12-24 hours.  The treated articles are resistant to the swelling and destructive effects of hot acid dye baths such as are used for dyeing wool. The articles may be obtained from solutions of peanut or soya bean globulins in alkaline or saline solutions or from their solutions in aqueous urea.  Filaments may be stretched during production, and washed with saturated sodium sulphate while under tension sufficient to prevent shrinking.  They may then be cut to staple fibre length, and bundles of fibres may be subjected to the insolubilizing treatment.

Abstract: 504,211. Photo-electric photographic exposure meters. ZEISS IKON AKT.-GES. Jan. 11, 1938, No. 915. Convention date, Jan. 13, 1937. [Class 40 (iii)] [Also in Group XX] A photographic camera comprises a photo. electric exposure meter in which the measuring instrument indicating the. photo-electric current is operatively connected with a mirror adapted to deflect a light beam in accordance with the deflections of the measuring instrument, and which includes means for bringing said light beam to a definite direction or for adjusting an indicator in accordance with the direction of said light beam, said means being operatively coupled with an exposure adjustment member of the camera so that said member is adjusted upon operation of said means. In the form shown, a moving coil galvanometer fitted with mirror 4 is electrically connected to the exposure meter 9 and with a variable resistance the adjusting member of which is coupled with the time adjustment member. The mirror 5 is rotatable and is mechanically coupled with the diaphragm-adjustment member of the camera. Light proceeding from the object to be photographed is used as an indicating beam, enters by the window 1 and is finally thrown on to-the scale 6 to be observed. In operation, the time adjustment member is set which adjusts the resistance, and the mirror 5 is moved to bring the light pointer to a predetermined position on the scale 6. This automatically sets the stop opening. Instead of the time adjustment member being connected with the mirror 5 it may be connected to an auxiliary indicator to be brought into a definite position with relation to the light beam on the scale 6. The auxiliary pointer may be a second light beam thrown on to the screen from a separate mirror that is connected to an adjustment member, the two beams being brought to coincidence. Concave mirrors may be used to form a spot on the screen.

Title: Method of applying a coating to heat sensitive materials
Inventor: HYDE JAMES L
IPC: F26B3/30
Filed: 1991-03-14
Abstract: A method and means for drying a thin aqueous-based coating on heat sensitive materials without boiling and without distortion or damage to the heat sensitive material or delicate surface thereof. Solvent-based adhesives are used in the production of articles of manufacture because of the ability to assemble the separate pieces immediately after the spray adhesive is applied. However, certain solvent-based adhesives attack the surface of the item to be covered, and in the case of videodiscs, the solvent in the adhesive may well contaminate the plastic surfaces or even the aluminum reflective layer of a laser disc. According to the present invention, a water based coating applied to a sensitive material is subjected to alternate sources of radiant heat energy and relatively cool air. The time of exposure to each source and the amounts of heating and cooling of the respective sources are maintained at levels sufficient to significantly decrease the time needed to dry the coating while limiting the temperature increase of the material to a level insufficient to deform or distort the material or surfaces thereof.
