Patent GB-178417-A (GB)
Abstract: 178,417. National Cash Register Co., (Assignees of Pein E. J. von). April 13, 1921, [Convention date]. Cash registers with item-printing mechanism. -In a key-set and operated machine provided with independent operating means for effecting the printing, such as is described in Specifications 10213/93 and 142,436, the item-printing operating means is automatically released for action when an item key has been fully depressed. In the embodiment described, the operating means comprises a motor the circuit of which is closed by the release of a spring-controlled bar upon the completion of the downward stroke of the item key or keys. The main shaft, rotated from the key coupler, is locked during the printing operation at the end of which the shaft is released to complete its rotation and enable the keys to resume their normal position. The main shaft 56, Figs. 14 and 17, is driven in the usual manner from the key-coupler 32, Fig. 10, and when it has made a half-rotation, a cam-groove 132 has forced a co-operating lever 134 pivoted at 135 into the position shown in Fig. 17 and thus allowed a lever 138 pivoted at 139 to rock so as to remove a pawl 149 from blocking a spring-controlled slide-bar 156. This bar therefore moves to the right and disengages an arm 129 from a clutch and switch device 162 (described in Specification 17534/08), and the motor is consequently thrown into circuit and drives the shaft 120 operating the printing-mechanism which may be that described in Specification 194,703. Meanwhile the rocking of the lever 138 moves, through an arm 146, Fig. 10, a bell-crank lever 35 so as to position its vertical arm under the key-coupled to prevent it from descending. At the end of the rotation of shaft 120 a cam-projection 173, Fig. 17, rocks a lever 175 coaxial with and attached to the lever 134 and thereby returns the latter to its normal position. The lever 138 therefore resumes its function of locking the slide-bar 156, which has then returned to normal position under the action of a cam 170. The bell-crank lever 35 has also been rocked to release the coupler so that the registering parts may all complete their movements. The lever 175 is held in either of its operative positions by a detent arm 183 and has an extending arm 189 which serves to prevent motion of the printing-shaft 120 when the levers 134, 175 are in the position shown in Fig. 14, that is during the first half-rotation of the main shaft 56. An interlock between the shafts 56, 120 is also provided by means of a lever 192, the ends of which co-operate with notched discs on the shafts. The Specification as open to inspection under Sect. 91 (3) (a) also comprises the subject-matter of Specification 194,703. Moreover, a crank to be used in place of the motor may be axially shifted into gear with the main printing shaft 120 and a spring-controlled arm bearing against a cam on this shaft may be provided to equalize the rotary effort. This subject-matter does not appear in the Specification as accepted.

Abstract: 577,954. Coating compositions; resins. SOHN, H. Dec. 16, 1942, No. 17879. Convention date, Dec. 19, 1941. [Class 95] Coating compositions are prepared by melting colophony with sulphur, dissolving the molten mass in a hydrocarbon, and boiling the resultant material with aluminium oxide, alumnium hydroxide, or a salt containing aluminium. By treatment with suphur, the melting point of the colophony is raised, and its viscosity in petroleum solution is greatly increased. Specified hydrocarbon solvents are petroleum, white spirit, naphtha, and the coal-tar fraction boiling at 230-270‹C. Specified aluminium salts are aluminium chloride, calcium aluminate, and an aluminium hydrocarbonate obtained by precipitating a soluble aluminium salt with sodium carbonate, separting in a moist state, and dehydrating in vacuo. The content of free resin acids may be reduced by adding an alkaline earth oxide, hydroxide or carbonate, and boiling. The coating compositions obtained have good spreading qualities, are compatible with pigments, and give durable and elastic films.

Abstract: 655,129. Reinforced concrete. FREYSSINET, E. July 2, 1948, No. 17888. Convention date, March 16, 1948. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 5, 1949.] [Class 20(iv] [Also in Group XXI] According to the Specification as open to inspection under Sect. 91, the floor 2 of a dam consists of vaults 26, Figs. 11, 12 (both Cancelled), resting on concrete beds and spaced from vaults 20 forming the water-retaining wall 3 by cast-in-situ concrete 4, the vaults 26, 30 and the concrete 4 being pre-stressed by reinforcements 27, 29 and by lighter reinforcements 46 at right angles thereto. Further reinforcements binds the concrete in the direction at right angles to the reinforcements 27, 29, 46. An upstream extension of the floor 2 comprises concrete slabs having tensional reinforcements parallel to the plane of the slab, in two directions at right angles, and a convoluted reinforcement to bind the concrete in the third direction. Jointing between the slabs is effected by laying spaced slabs 11, 11<SP>1</SP>, Fig. 10 (Cancelled), on an under slab 13, and applying in situ concrete 12 to embed the exposed ends of the tensioned reinforcements. The floor 2 and spillway 33 are strained against the ground by tensioned reinforcements in concrete piles 6, 45. These are made by sinking a bore, filling the lower end with concrete 7a which is allowed to set around the reinforcement 7, preventing the rest of the reinforcement from adhering to the rest of the concrete, and applying tension to the reinforcement at its upper end. The passages 25 between the concrete beds 23 are used for tensioning and draining. This subject-matter does not appear in the Specification as accepted.

Title: A new or improved process of treating starch giving a product for use in brewing and in confectionery and allied manufactures
IPC: C12C7/04
Filed: 1923-07-11
Abstract: To produce a mixture of maltose and amylopectin derivatives for use in brewing, confectionery, &c., starch-paste, which may be first liquefied by the action of malt-grist, is treated with an extract of ungerminated grain such as barley, and subsequently or simultaneously with an extract of germinated grain until it ceases to give a colour reaction with iodine.  In some cases the treatment with extract of ungerminated grain is continued until upwards of 60 per cent of the starch present has been saccharified and the treatment with extract of germinated grain omitted.  Dry grists from germinated or ungerminated grain may be substituted for the extracts.  For the extract of germinated grain may be substitued an extract of animal pancreas or other animal or vegetable extract containing similar enzymes, which convert the amylopectin derivatives into isomaltose.
