In swinging out, the end G<15> of the block G<5> engages a block or buffer G<17> on the breast beam &c. whereby the block is operated to open the jaws of the gripper and free the weft. The guides F are pivoted and spring-controlled so that they and the rod R can be moved by the going part at the beat up. At this time the rod R has no traversing movement as its stud is in one of two races T<1> communicating with the cam groove T by means of pivoted gates. The rod R may be provided with grippers at each end so as to serve for two adjacent looms, or two rods may be used. Several wefts may be used. The gearing employed comprises partly toothed pinions whereby a dwell may be given to the top and bottom shafts.

Abstract: 1,029,351. Automatic exchange systems. SIEMENS & HALSKE A.G. April 23, 1964 [April 26, 1963], No. 16788/64. Heading H4K. A PABX has some subscribers with impulse transmitters and others with code senders, both sets of subscribers having access to the same relay sets which distinguish between the types of substation gaining access. The substations are connected to the relay sets over a line finderfinal selector, the code sending substations being multipled to each relay set over one bank of the finder-selector so as to operate a code-sending relay in the relay set. The code sending relay is energized by discharge of a capacitor, connected up on seizure of the relay set, and connects up a decoder which governs an impulse generator repeating each code received as impulses to line. The impulse sending substations produce no switching in the relay set when this is seized, the relay set standing normally in a condition to repeat the received impulses to line. The impulse sending stations have an earth key actuation of which during a connection with the public exchange enables the substation to transfer the connection to another substation designated by dialling. The code sending substations obtain this facility by means of a particular code. The relay sets over which such transfer paths are set up may be of a kind to handle calls from both types of substation or may be of different sorts depending on the type of substation.

Abstract: 846,383. Filing papers. ZIPPEL, G. A. May 31, 1956, No. 16919/56. Addition to 751,152. Class 146(1). A folder or like document holder is capable of engaging one or more thin edge portions of a rail and of supporting documents in a plane perpendicular to the rail, a recess in an edge of the holder receiving the thin edge portions of the rail, the recess being of such a shape that when the folder is in full engagement with the rail the edges of the recess touch the thin edge portions at two separate points and the folder cannot be disengaged solely by linear movement in its own plane but can be disengaged by rotation through a small angle in its own plane followed by linear movement. As shown in Fig. 1, the rail 14 is of inverted T-shape in cross-section, the flanges of the T fitting into recesses in the upper edges of side walls 19, 20 of a folder having its closed end 18 downwards. The recesses are strengthened by plates 21 and form two noses 12, 13 on each side wall which engage over the flanges of the rail. To unhook the folder it is first moved slightly to the left from the Fig. 1, position to disengage the nose 12 from the rail, then rotated through a small angle in an anti-clockwise direction, Fig. 2, and finally moved to the right to disengage the nose 13 from the rail. In modifications the recesses and rail have different shapes. In Fig. 9 a T-shaped projection 60 in each recess is engaged in a slotted tubular rail 59. In Fig. 12 the recesses are of the same shape as those of Fig. 1 but are formed in those edges of the side walls which are adjacent to the folded edge of the folder. The recesses engage a T-shaped rail 114 mounted in a drawer and the folder rests at its other end on a further rail 117 also mounted in the drawer.

Title: An improved silica gel for use in building materials
IPC: C04B12/04
Filed: 1944-09-06
Abstract: A thixotropic stabilized dispersion of hydrated silica gel for incorporation with mortar, cement, or concrete, is prepared by precipitating the gel from an aqueous solution of an alkali metal, e.g., sodium silicate by an acid or acid-forming substance, subjecting the product to vigorous agitation to form discrete gel particles, e.g., not larger than 5mm., and stabilizing it by the addition of a surface active or emulsifying agent.  The precipitating agent may be, for example, sulphuric, hydrochloric, acetic, tartaric or oxalic acid, potassium bisulphate or bitartarate, sodium bicarbonate, carbon dioxide or sulphur dioxide.  The reactants should be in weak solutions when strong mineral acids are used, e.g., less than 30 per cent. and preferably between 5 and 10 per cent. for the acid and less than 18 per cent. and preferably between 6 and 10 per cent. for the silicate (calculated as silica), or stronger solutions may be used in other cases, e.g., 30 or 36 per cent. solutions of silcates with solid acidic substances.  The silicate is preferably added to the mineral acids, when these are used.  Stabilizing agents may be esters or ethers containing free alcoholic hydroxyl groups, e.g., partly hydrolysed fatty glycerides such as glyceryl monostearate, sulphonated higher alcohols or esters, e.g., sulphonated lauryl alcohol, or cation active surface agents, and they may be used to give amounts of 1 or 2 per cent. in the product. After precipitation, the gel particles may be sieved, washed and resuspended in water before stabilization and further comminuted by passing through a sieve of, e.g., 1 1/2 mm. mesh or homogeniser nozzle after stabilization.  The product has a gel to aqueous phase ratio of about 9 to 1.  Amounts up to 25 per cent. of calcium or magnesium chloride in the form of a 50 per cent. solution may be incorporated with the dispersion.ALSO:A thixotropic stabilised hydrated silica dispersion comprising a suspension of discrete gel particles in an aqueous medium to which a stabilising agent is added (see Group III), and which may contain up to 25 per cent. by weight of calcium or magnesium chloride, may be incorporated with building and constructional materials such as mortar, cement, and concrete mixtures such as those based on Portland, high-alumina, blast-furnace, and pozzolanic cements.
