Abstract: 1,273,169. Coated products. CONSO ENG. CO. 4 Dec., 1969 [16 Dec., 1968], No. 59328/ 69. Heading B2E. [Also in Division B5] A thermo-adhesive carpet-seaming tape comprises a thin and limp substrate having high tensile strength and dimensional stability at least in a transverse direction and a plurality of spaced apart rows of solidified flexible thermoplastic adhesive adhered to one face of the substrate, the cross-sectional areas of the rows being sufficiently great in-relation to the spacings therebetween so that on heating the rows will flow together into a continuous layer. The substrate is of woven, knitted, openmesh, or felted textile fabric of rayon, nylon or glass fibre or may comprise a strip of crinkled or creped paper having weft-yarns of rayon or glass fibre stitched thereto by warp-wise chains of knitted stitches of cotton. When an open-mesh or knitted fabric is used, it is secured to an underlying adhesive-barrier strip. The adhesive may be "Thermogrip" (Trade Mark) or polyethylene-based and is applied to the substrate in spaced-apart tracks or ribs (e.g. by extrusion) or in the form of beads.

Abstract: 1,270,380. Cheese manufacture. MKT-TEHTAAT OY. 16 Dec., 1970, No. 59684/70. Heading A2B. An apparatus for manufacturing Cheddar type cheese, comprises a ripening tank having a movable perforated base which, in use, moves from the upstream to the downstream end of the tank, a mincing device for mincing the ripened cheese, a press plate located above the tank, a cutter for cutting a cheese mattress resting on the movable base, and a conveyor extending from the downstream to the upstream end of the tank for feeding the minced cheese back into the tank for final pressing of the cheese. The conveyor may be located either between the mincing device and salting device or between the salting device and upstream end of the tank. A suitable apparatus is shown in Fig. 1 wherein curd and whey are fed to a tank 1 which tank may have perforated walls and has as a base a perforated endless wire screen 8. The wall 5 is vertically movable to permit transfer of curd pieces from the tank. In operation, the curd after a preliminary pressing by the plate 11 is transferred as pieces 27, by movement of the screen 8 and cutter 33, on to the conveyor 14, the pieces then passing between rolls 16 and 18 which rolls are provided with cutters 17 and 19. The pieces are thus pressed and cut into strips and are subjected to further cutting by the vertically movable cutter 20. The resultant pieces are transferred via conveyors 15, 22, 23 and 24 to salting device 25 and then back to the tank. When the tank is sufficiently full of minced or salted cheese, a final pressing step is carried out.

Filed: 1978-10-18
Abstract: An ore sintering process where a mixture of ores is spread on a continuous movable grate as a continuous layer of uniform thickness, the layer is ignited on the surface and combustion is made to progress downwards towards the grate by drawing or forcing air through the layer, the rate of travel of the grate being varied to suit the progress of combustion. Continuous sampling is preformed of the products of combustion in the form of gases which have passed through the bed being sintered, and the ensuing samples are subjected to rapid quantitative analysis especially to ascertain the carbon monoxide and dioxide, oxygen and nitrogen contents. The results of the analyses are processed and compared with values previously determined as optimal and on the basis of this comparison control is exercised on the progress of combustion and sintering of the layer by regulating the rate of travel of the grate.
