Title: Improved polyurethane foam products and process of preparation thereof
IPC: C08J9/00
Filed: 1956-09-20
Abstract: A process for preparing soft, resilient, low density polyurethane foam from an essentially hydroxyl-terminated polyester, a polyisocyanate and water comprises incorporating finely divided mica into the reaction mixture.  5 to 50 parts, preferably 15 to 30 parts, of mica to each 100 parts by weight of polyester may be used.  It may be natural or synthetic and preferably has an average particle size of less than about 200 microns.  The polyesters are preferably linear, although they may be derived from mixtures containing up to about 5 mol. per cent of trimethylol propane or 3.5 mol. per cent of pentaerythrital, based on the dicarboxylic acid.  The molecular weight of the ester may be from about 500 to 5000, and preferably is between 1200 and 1800.  Specified polyisocyanates are tolylene, ethylbenzene, isopropyl benzene, diethyl benzene and m-phenylene diisocyanates and p,p1-diisocyanato-diphenyl methane.  As accelerators there may be added to the reaction mixture potassium hydroxide, organic bases such as tertiary amines and a soap such as potassium ricinoleate.  In examples, tolylene diisocyanate is stirred into a heated mixture of hydroxyl terminated polyethylene adipate and mica, followed by water and aqueous potassium ricinoleate.  The foamed product obtained is rinsed with water and heated at 100 DEG C. The properties are given of foams prepared using mica in different amounts, particle size and type.  A polyester from diethylene glycol and adipic acid can be employed similarly.

Abstract: 868,099. Pipe stoppers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Sept. 7, 1959 [Sept 10, 1958], No. 29051/58. Class 99(1). In securing a plate 7 within the bore 1 of a pipe at least one abutting shoulder 4 and at least one retaining shoulder 5 are provided in the surface of the bore, each shoulder 5 having a surface which is inclined to the face 11 of the plate 7 when the plate is inserted within the bore 1 so that the face 8 of the plate abuts against the shoulder 4. A flexible compressible locking member, such as an open coiled steel spring 9, is adapted to extend around the surface of the bore and to engage with each of the inclined surfaces 5 and with the face 11 of the plate, the angles of inclination of the surfaces 5 being such that, as the spring 9 expands in length, it tends to force the face 8 against the shoulder 4 so as to secure the plate 7 within the bore. As shown, the shoulders 4, 5 constitute the sides of a groove 3 extending continuously around the bore 1. The side 5 of the groove 3 may extend radially and the inclined surface may be formed at the outer edge of the face 11 of the plate 7.

IPC: F21V5/00
Filed: 1960-08-23
Abstract: 987,243. Light controlling panels. HOLOPHANE Ltd. July 26, 1961 [Aug. 23, 1960], No. 29149/60. Heading F4R. In a panel having a prismatic or similar formation for controlling the light, the formation is protected by a film of plastics material sealed round the edges of the panel. If the panel is to be light transmitting, a translucent film is used. The invention may be applied to plane or curved panels. The panel 11 has an edge flange 12 to which the film 14 is sealed and may have integral or attached pillars or ribs to afford support for the film at intermediate points. The flange 12 may be higher or lower than the tops of the prisms 13 or may be omitted, the film then resting on the tops of the prisms. In a curved panel some of the prisms on the convex side may be of increased height so that the film bears on these. The space between the panel and the film may be partially evacuated and a small water absorbing element 16 may be included to avoid condensation during sealing. Where the panel is of plastics material, the film may be secured in place by welding or heat sealing. The film may be tinted or may be rendered diffusing by imparting a diffusing pattern or by incorporating particles in the film.

Title: Improvements in image reproduction
IPC: G03G13/16
Filed: 1963-07-24
Abstract: 1,033,523. Printing apparatus. RANK XEROX Ltd. July 24, 1963 [July 24, 1962], No. 29306/63. Heading B6C. Reproductions of an image are formed by presenting a tacky support base surface bearing a resist image into contact against a backing containing a releasable surface film and then separating the base from the backing whereby the film is released to the base in the surface areas devoid of the resist image. In the apparatus shown for reproducing an image formed by xerography the developed image arising from the xerographic process is transferred from the drum 57, Fig. 7, to a web 30 which has an adhesive surface contacting the drum and which may be a polyester film "Mylar" backed tape. The web 30 now containing the image adhesively transferred from the drum, is caused to be applied against a web 31 drawn for a supply roller 90. This web 31 may be a polyester film having a releasable surface film of an evaporated metal coating of antimony, aluminium or silver. Binders and/or pigments may also be incorporated in the releasable film. The latter may be a conductive material such as to effect utilization of the resulting reproduction in the printed circuit art. The webs 30 and 31 are then separated the web 30 thereafter comprising one form of image as a negative projection transparency which advances from guide roller 82 to roller 95. Beyond the latter roller the web may optionally move past a projection system 97 prior to reeling on a take-up roller 84 driven through a slip-clutch 86 by a motor 85. Web 31 comprises an opposite complementary image and may, if desired, form a positive image projection transparency which advances over guide roller 91 to roller 96. It may move past a projection system 102 before winding on a take-up roller 92 also driven by the motor 85 through slip-clutch 86. Fig. 8 shows an apparatus automatically processing flat xerographic plates containing a powder image. In this apparatus a developed plate 11 is manually inserted into the bite of feed rollers 119 and 120 into pressure engagement against the adhesive surface of a web 30. After transfer of the image on to the web 30 the latter is passed into contact with a web 31, pressure contact being applied by the guide rollers 126 and 150. The two webs are thereafter separately guided to respective feed roller pins 154, 155 and 156, 157 effecting thereby separation from one another. Complementary images are formed on the respective webs. It is envisaged that the image may be formed on the plate or drum to be presented to the web 30 by printing methods other than xerography. For example, the web 30 or the releasable film on the web 31 may be directly imaged by stencilling or by photography or by other forms of electrography and electrophotography.

Title: Improvements in and connected with tin plate branning or grease removing machines
IPC: C23G5/00
Filed: 1921-11-05
Abstract: 191,526. Davies, S., and Lewis, J. Nov. 5, 1921. Cleaning.-Tin plates are conducted through a branning-machine by an inclined endless belt which carries the cleaning-material and brings it into intimate contact with the surfaces of the plates. Curved guiding means cause the upper run of the belt to take the form of two adjacent troughs, reversing-means being arranged at the crest between the two troughs for causing that side of the plate which was lowermost during its travel through the first trough to become uppermost during its travel through the second trough. The motion of the upper run of the belt continuously raises the cleaning-material, which then falls on the plate passing through the trough. The belt 11 is driven from a drum 2 and passes over an adjustable drum 5, by means of which its tension is regulated. The troughs are formed by a supporting roller 9 and two pairs of idle flanged discs 18 which bear against the preferably thickened edges 11<a> of the belt. The passage of the plate with the belt is ensured by rollers 28, 29, 30, 31 which bear against the belt, and may be provided with spaced rubber rings on their peripheries. The plates, as the leave the first trough, are carried up between fixed grids 38. 39, the lower edges of the plates being carried on by the belts, and the plates being thereby reversed as they pass into the second trough. The plates may be fed to the machine by an endless conveyer driven from the lower drum 5, and a cover 42 may enclose the machine to prevent spreading of dust. The discs 18 may be replaced by curved stationary guides fixed to or formed on the inner sides of the side frames 17 of the machine.
