Title: Low stretch sectional abrasive belts and their method of manu facture
IPC: B24D11/02
Filed: 1972-06-06
Abstract: 1357292 Abrasive belts NORTON CO 6 June 1972 [7 June 1971] 26399/72 Heading B3D [Also in Divisions C4 and D1] The base for an abrasive belt comprises a woven fabric 11 having a fabric cover of at least 98%, i.e. an air space of less than 2% has on one face a dry, tack-free heat hardenable resin 15 that penetrates at least half way through the thickness of the fabric. Preferably the woven fabric is first treated with a non-slip agent, then the resin 15, followed by a maker adhesive coating 12, abrasive particles 13 and a final size coating 14. The fabric may be of cotton, polyamide, polyester polynosic rayon or blends thereof. In the example a cotton sateen has a 4/1 weave, 104 warps/inch of yarn number 17 and 60 wefts/inch of yarn number 6À5. A non-slip agent (a hydrogenated resin, a protein/ terpene blend, a gum resin or an ethoxylated fatty acid ester) is applied from an aqueous bath and the fabric calendered and dried. Following backsizing the twill side was coated with an aqueous solution of two phenol-formaldehyde resins 15 curable at 225‹ and 300‹ F. respectively which is then forced at least halfway but not more than 75% through the fabric by passage of the fabric so that the non-coated side contacts a series of steam-heated cans. Alternative resins 15 are epoxy, polyester and urea formaldehyde resins. The maker adhesive coating 12 is phenolformaldehyde. The exemplified abrasive is silicon carbide; alternatives are alumina garnet, flint, diamond and fused zirconiaalumina. Finally a size 14 of phenol-formaldehyde is applied. Sections are cut from the product at an angle of 73 degrees 30 minutes to its longitudinal axis. The resulting parallelograms are lap or butt joined along along their long sides to form an endless abrasive belt of greater width than could be conveniently produced in one piece The weft yarns are preferably stronger than the warp since the running direction of the belt is closer to the weft direction The closely woven cloth plus impregnant results in no more than 4% elongation of the belt at 100 lbs/in width tensile stress.

Title: Process of and materials for colour photography
IPC: G03C1/815
Filed: 1937-05-10
Abstract: 501,002. Colour photography; photographic developing processes. KODAK, Ltd. May 10, 1937, No. 26471/38. Convention date May 9, 1936. Divided out of 500,826. [Class 98 (ii)] A process of producing colour developed reversed silver halide images in a three-layer photographic element, of the type in which the upper layer is not specially colour sensitized and the other layers are respectively sensitized to the red and green regions of the spectrum and in which the colour sensitizer in the middle layer is resistant to the action of photographic developing baths and mild silver-oxidizing baths and /or there is a yellow filter colouring matter in the upper layer or between the upper layer and the middle layer which is not destroyed by photographic developing baths or which is not destroyed by photographic developing baths and silver-oxidizing baths, is characterized in that the reduced silver is removed from all the layers before exposure of the residual silver halide image of the middle layer but after exposure and colour development of the residual silver halide image in the lower layer or in the lower layer and the upper layer. Suitable sensitizers for the middle layer are: (a) for red, 2 : 21 dimethyl-8-ethyl-3 : 4 : 31 4<1>-dibenzthiacarbocyanine iodide ; (b) for yellow-green, 2 : 1<1>- diethyl-3 : 4-benzthia-2<1>-cyanine iodide. If a very sharp blue image is desired the middle layer can be sensitized to the extreme orange red as well as the genuine red with 4: 4<1>-dichloro-2 : 2<1> : 8-triethylthiacarbocyanine chloride. Several examples of the process are described, in one of which development of the residual silver halide of the upper layer is effected by alkaline-solutions of the leucoforms of various yellow vat dyes preferably with exclusion of atmospheric oxygen to prevent fog as described in Specification 498,876, and in, another of which the middle layer is exposed from both sides to white, blue, or ultra-violet light or to soft X-rays and developed purple. In order to avoid the effect of local under-exposure in the lower layers all the layers are first saturated with developing agent in high concentration and are then treated with weak alkali to effect development. Alternatively a concentrated developing solution is allowed to diffuse into all the layers at as low a temperature as it is possible to employ without alteration in composition of the solution and the development process started or accelerated by warming the layers to room temperature or above. Specifications 427,517,427,520,454,498,454,499, 464,622, 500,717, and 500,793 also are referred to.

Title: Improvements in and relating to controllers for electric motors
IPC: H02P7/34
Filed: 1919-10-30
Abstract: 158,334. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 30, 1919. Master control systems.-The main motor controller is caused to copy the movements of the master controller bv means of a pair of hunting contacts. The invention is particularly designed for motors required to run at a number of definite speeds, and is described in application to such motors provided with a Ward-Leonard method of control diagrammatically indicated in Fig. 2. According to this scheme, a working motor M is connected to a generator G having three steps of series resistance r, r<1>, r<2> and parallel resistances r<3>, r<4> for the field GF, and the motor field MF is further regulated by four steps of resistance R, R<1>, R<2>, R<3>. Electromagnetic contactors acting to short-circuit the resistances are connected to fingers of a drum controller C, Fig. 1, which has eight running positions giving eight definite speeds of the working motor. It is set to any selected position by turning a master controller MC to a corresponding position, whereby a segment 20 or 21, according as the controller is turned forwards or backwards, engages a hunting contact 19 mechanically connected to the drum controller C. A pilot motor PM, on receiving current either from the segment 20 or 21, starts and drives the controller C to follow the master controller, the movement ceasing when 19 passes off the segment 20 or 21, i.e. when the selected position has been reached. In order to cause the generator field to build up quickly, a contactor winding 13, adapted to short-circuit the resistances r, r<1>, r<2> simultaneously, is connected to the line through the hunting contact 19, so that the field is subject to an increased current during the time that the drum controller is passing through the intermediate steps to the selected position.
