Abstract: 500,071. Securing wood &c. panels to floors and walls. NOEL, R. E. L., and MOSAIQUES NOEL. Dec. 20, 1937, No. 35296. [Classes 20 (iv) and 107] A process for use in applying to a floor or wall surface a panel comprising a plurality of wood, marble, or other elements, consists in the application to the elements of cement in the form of pellets arranged in predetermined spaced positions. The panel thus treated is applied to, and pressed against, the floor or wall surface. A device for applying the cement pellets to the panel comprises, as shown in Figs. 3 and 4, a foraminous plate 2 having spaced apertures 3 through which the cement passes to the panel disposed beneath the plate 2 on a base 1.. The plate 2 is hinged at 6, and the base 1 is provided with two straight-edged members 4, 5 which serve to position the panel. The elements of a panel are first cemented in correct relative position to a paper sheet, and the panel so formed is then placed on the base 1 with the paper sheet lowermost. The required amount of cement is placed on the plate 2 and spread across the plate so that it is caused to pass through the apertures 3 and form the pellets. If desired, the hinged edge of the plate may be provided with a curved extension 8 which serves as a reservoir for the cement. The perforations 3 are so disposed as not to lie over joint spaces between elements. The panel may take the form of a plurality of wood strips disposed in groups at right-angles to each other The underside of these strips may, as shown in Fig. 7, be provided with longitudinal dovetail edge grooves 11, 12 and longitudinal intermediate grooves 10 about 3 mms. wide and 2 mms. deep, and spaces of the order of 0<.>2 to 0À3 mms. are provided between the strips. The pellets applied to the panel may consist of a magnesium cement comprising a relatively high content of calcined magnesia and a relatively low content of magnesium chloride, and these pellets may be of 1 to 2 mms. in thickness so that, when the panel is pressed against a floor base, little or no cement extends into the joint spaces and a number of free spaces is provided in the cement mass. The floor base may be previously treated with a milk of magnesian cement.

Title: Improvements in or relating to the recording of sound tracks on film intended for colour photography
IPC: G03C7/24
Filed: 1946-11-29
Abstract: 626,726. Photographic colour picture and sound films. HARRISON, G. B., and ILFORD, Ltd. Nov. 29, 1946, No. 35489. [Class 98 (ii)] Into a multilayer film comprising a support carrying three silver halide emulsion layers selectively sensitive to red, green, and blue light, and separated by barrier layers, and which film is developed by reversal, preferably with the colour-formers in the developing solutions, a negative sound track is recorded (by direct exposure or by printing) by blue light or by light containing red or green in addition to blue so that the sound track image is present in the blue-recording layer and one or both of the other layers, this negative sound track is developed in a non-colour forming developer and thereafter, as a step prior to, subsequent to, or intermediate between the steps of colourdeveloping picture images in the material, the sound track area of the film is exposed with green light incident on the blue-sensitive layer, to produce a positive sound track record in the green-sensitive layer, and this record is developed to colour. Exposure and development procedures are described by which this positive sound track produced in the original greensensitive layer may be formed of green, cyan, yellow or magenta dye, or of dye different from any of the picture dyes; if desired the greensensitive layer may itself contain a colourformer such as 1-(4<SP>1</SP>-phenoxy-3<SP>1</SP>-sulphophenyl)- 3-stearyl-5-pyrazolone and the sound track may be formed wholly in the dye from such colourformer or jointly from such dye and a dye from any other colour-former. In a specific example a multilayer film in which the barrier layers'are ones incorporating colloidal silver sulphide together with a very small amount of silver halide, as particularly described and claimed in Specification 595,582, the latent positive sound record in the green-sensitive layer is colourdeveloped at the same time as the picture record in the red-sensitive layer, to produce the sound track in blue-green dye. In all cases the final positive sound track is printed by green light through the negative sound track lying in the blue recording layer, and it is mentioned that the positive sound track so produced is not of the same character as one made by exposure or chemical fogging and colour development of silver halide remaining after non-colourdevelopment of a negative sound track. The sensitizing dye in the green sensitive layer must be one, such as 1,1<SP>1</SP>-diethyl-pseudocyanine iodide, which is not destroyed in development baths.

Abstract: 1,105,824. Layering fabrics. STAFFORD TOOL & DIE CO. Ltd. 18 May, 1966 [20, Aug., 1965], No. 35803/65. Heading D1S.  A semi-automatic feeding arrangement comprises means 11 to support a plurality of lengths of sheet material, a pair of power driven feed rolls 18, 19 through which the lengths are fed while being laid up into a pile 25, and means 26 associated with the rolls 18, 19 and responsive to a slackening or tautening of the tension in the pile 25 to respectively stop or start the rolls 18, 19. As shown, six rolls 12, .. 17 of textile fabric are rotatably supported on a trolley 11 either on spindles passing through the rolls or, for example rolls 13, 17, by being laid in boxes each containing small rollers. Alternatively rolls, bolts or loose lengths of fabric are accommodated in bins on the trolley. Fig. 3 (not shown). The rolls 18, 19 form the fabric into a pile and it passes through a power press 21 to a table 24 having a sliding top faced with a material sufficiently strong to withstand the pressure of a cutting tool but resilient to prevent damage to the cutting edges of the tool. In operation, fabric is passed between the rolls 18, 19 opened by a handle 20 and between the open platens 22, 23 of the press 21 after which the rolls 18, 19 are closed. The operator stands by the table 24 and pulls the pile 25 taut to raise an arm 26 which actuates a switch to drive the feed rolls 18, 19 by a motor 27. The rolls 18, 19 feed the pile towards the press 21 whilst the operator only exerts sufficient pull to hold the pile taut. When the pile has reached the end of the table 24, the operator allows the pile to sag to cause the switch 26 to drop and stop the rolls 18, 19. Forme or strip steel cutters are placed on the pile on the table 24 and the table top is pushed into the press 21 which is then closed. The press 21 is opened, the table top withdrawn and the cut fabric separated from the waste fabric. The operation is then repeated. A transverse cutter- (not shown) may be fixed to the end of the table 24 to cut the waste fabric from the pile. A tray 34 may be provided on the trolley 11 into which the sagging fabric may droop during cutting. In a modification (not shown), the trolley 11 is replaced by a smooth topped table for carrying sheets of fabric and which is mounted on castors.
