Title: Improvements in or relating to books containing classified matter in tabular form
IPC: B42F21/00
Filed: 1948-01-20
Abstract: 654,405. Books, etc.; indexing. CORDONE, M. Jan. 20, 1948, No. 1725. Convention date, Jan. 20, 1947. [Class 16] A book containing classified matter in tabular form such as a dictionary, numerical tables or catalogue comprises a plurality of mutually superimposed individual prebound sections each constituted by a plurality of superimposed sheets folded centrally and nested one within the other, the leaves of each section having reference bearing tabs extending in terraced form substantially from top to bottom of the leaves in that section, so that the sections form a thumb index extending continuously from top to bottom of the successive sections. The superimposed leaves of each section with the exception of the last leaf are cut away as shown in Fig. 2 to provide terraced tabs 21 .. 36, extending substantially from top to bottom of that section. Each tab bears a reference or references corresponding to an item of classified matter at one end of a column on the leaf bearing the tab. The location of each section may be indicated by means of tags such as S and T when the book is made up of sections of equal width superimposed in neutral registration as shown in Fig. 2. Alternatively, the book may be constituted by sections of increasing widths echeloned as shown in Fig. 5, in a direction transverse to that in which the classified matter arranged in columns on the pages is scanned in which case the cover 70 is provided with a wedgeshaped member 71. In a modification, Fig. 6 (not shown) sections of constant width are echeloned longitudinally of the pages the tabs being provided along a transverse edge of the book ; in this case wedge members are provided on the inside of both covers of the book one at the top and one at the bottom thereof. In a further modification, Fig. 7 (not shown) the book comprises main and secondary parts each having its sections echeloned as shown in Fig. 5 to provide an index. The main part is carried by a wedge-like part while the supplementary part is carried by a hinge strip such that when the book is closed the terraced tabs interfit. In all constructions the index may appear along the left-hand edge of the book instead of the right-hand edge to facilitate manipulation of the book with the left-hand. The references on the tabs comprise one or more letters or numerals each of which by reason of its formation and/or position on a tab establishes the position in which that letter or numeral occurs in the classified item to which that letter or numeral refers. Additional references may be applied adjacent to individual items on the leaves.
Patent GB-182829-A (GB)
Title: Manufacture of starch
IPC: C08B30/04
Filed: 1921-01-11
Abstract: Starch is obtained from wheat flour by the action of a single proteolytic enzyme such as pepsin or trypsin which is without action on starch or its cellulose envelope but which converts the insoluble nitrogenous constituents of the flour into soluble substances which can be removed by water.  In an example a mixture of pepsin, water, and hydrochloric acid is heated to 40 DEG -50 DEG  C., the flour being then added and the heating continued till the density of the liquor remains constant.  The amount of pepsis employed is 0.04 per cent of the weight of flour.  When the reaction is complete the liquor is separated from the starch in a centrifuge, the starch being intermittently washed with water till free from acid.  If trypsin is employed it is dissolved in a solution of sodium carbonate or bicarbonate.  The starch is removed from the centrifuge and dried. Any gluten remaining in the starch may be removed by a solution of sodium hydroxide.  The nitrogenous liquor obtained as a by-product can be used as a fertilizer or as a base for food-stuffs.

Abstract: 1,196,841. Welding by fusion. H. M. WENZLAFF. 15 Jan., 1968 [4 Feb., 1967], No. 2072/68. Heading B3R. In a machine for welding reinforcing members S to a plate P, each reinforcing member is fed in turn to a welding station along a path transverse to the direction of feed of the plate P, is aligned and clamped to the plate P and is welded. The plate P is fed step-by-step along a roller bed by grippers on carriages, the grippers being transversely adjustable to align the plate P. A reinforcing member S lowered into a roller guide channel by a crane is pushed by a device 3 to slide on to the plate P. The member S is gripped between two sets of hydraulically actuated clamps 21, one set being moved to engage an adjustable stop 26 and the other set than pressing the member S against the accurately aligned first set. The aligned member S is gripped by vertically acting hydraulic clamps 19 mounted on a bridge 18 extending across the plate P. The aligning clamps 21 which are mounted on a frame 22 slidable vertically in rollers 23 on the bridge 18, are released and the frame 22 is raised . The plate P at the welding station is supported on a transverse bar resting on an adjustable wedge arrangement so that by variation of the height of the bar the plate P is pre-stressed to compensate for the stresses set up by welding. A pair of welding heads 49 are mounted on a carriage 41 having rollers 43, 44 engaging the bridge 18. Each welding head carries a work engaging roller 51 and is suspended from a mounting having a vertical guide pin sliding in a roller guide 56 and a piston forming part of a single acting pneumatic ram 52. During welding low pressure in the ram 52 takes most of the weight of the welding head off the roller 51 and, when welding is completed high pressure in the ram 52 raises the welding head. The welding heads are adjustable transversely by pneumatic rams 58 on the carriage 41. The wheels 43 of the carriage 41 are connectable by clutches to either of motors 46, 46 one of which provides a slow but variable welding drive and the other of which provides a fast non-welding traverse.
