Abstract: 1,176,087. Making tablets. ALBERTOCULVER CO. 26 May, 1967 [31 May, 1966], No. 24545/67. Headings ASB and A5E. [Also in Divisions A2, C5 and C6] Tablets are prepared by triturating, in the presence of moisture, a powder containing two separate ingredients which react together in the presence of water to produce a gas, with a volatile organic solvent in which at least one constituent of the powder is soluble, moulding the resultant mass into tablet form, and then drying the tablet. Preferred gas-forming ingredients are carbonates or bicarbonates (e.g. of Na, K or Li) with a water-soluble carboxylic acid (e.g. citric, tartaric, maleic, fumaric, succinic, adipic, itaconic or tricarballylic acid). The organic solvent may be ethanol, 2-propanol, chloroform, 1-butanol or acetone, or mixtures of these. The proportion of solvent used is generally about 3 to 40 mls. per 100 gms. of mixed powdered ingredients, and it may contain up to 10%, preferably 0.05 to 3% by weight of water. A pharmaceutical tablet of the invention, containing aspirin and monocalcium phosphate, is prepared. Example 7 describes an effervescent disinfectant tablet containing cetyl pyridinium chloride.

Abstract: 282,511. Midland Coal Products, Ltd., and Ingman, C. Oct. 5, 1926. Coking and carbonizing processes.-Low grade gas produced in a primary coal or briquette carbonizing retort is utilized to, carbonize the charges in one or more secondary retorts, the gas being burned and the combustion products used to superheat steam which is passed through the secondary retorts. Two steam superheaters may be employed, which are heated alternately by the hot combustion products. The charge in the primary retort may be heated by partial combustion of the briquette charge as described in Specification 242,783. The Provisional Specification describes also a modified process in which the steam, passed into the secondary retorts may be in part or wholly replaced by the combustion products of the gas from the primary retort.

Title: Improvements in or relating to means for controlling the frequency, the load distribution and the synchronous clock time in an electric power grid
IPC: H02J3/06
Filed: 1954-08-30
Abstract: 788,395. Automatic control systems. SIEMENS - SCHUCKERTWERKE AKT.- GES. Aug. 30, 1954 [Aug. 29, 1953], No. 25190/54. Drawings to Specification. Class 38 (4). The Specification states that in an electric power grid system it is known to control the prime movers (i) by the usual speed governors; (ii) by the integrated frequency error; (iii) by the algebraic sum of signals representing the frequency error and transferred load at the points of connection between different zones of the grid, Fig. 1 (not shown), whereby the load variation is taken up by the zone in which the change of load has occurred. The Specification proposes that in each zone additional control signals shall be used, viz :-the first and second differentials of the frequency error and the first differential of the transferred load, to assist in rapid regulation. These signals (like the frequency error and transferred load at point of connection to the grid) are arranged to be additive in zone in which a load variation has occurred, and cancel out in the other zones, Fig. 2 (not shown).

Abstract: 1,212,994. Photographic liquid development. GEVAERT-AGFA N.V. Nov.28, 1967 [June 2, 1967], No.25646/67. Heading G2A. A method of developing an imagewise exposed heat-sensitive material which becomes more or less soluble in a given solvent an exposure comprises feeding the material into an apparatus comprising an endless conveyer belt, means for driving the belt, pressure means for pressing the material into firm contact with the belt and rotatable rubbing means having a resilient and porous surface disposed so as to make rubbing contact with the exposed surface of the material whilst it is in contact with the belt and the peripheral speed of the rubbing means being higher than the speed of the belt; the material being fed on to the belt and pressed into contact therewith by the pressure means whilst the belt is in wetted condition and then developed by the rubbing means which is  wetted with the given solvent so that the more  soluble areas are removed. Excess liquid may be removed from the developed material by squeegee rollers. As shown, the exposed material is fed on to endless belt 94 via slot 91; the belt being wetted by liquid in tray 108. The material is pressed into contact with the belt by pressure rollers 98 and 99 so that most of the liquid on the belt is squeezed away leaving a thin layer to ensure good adherence of belt and material. Developing liquid is pumped by pump 112 from conduit 111 to nozzle 114 which is a metal tube which extends transversely of the apparatus so the liquid sprays on to the belt as shown by arrow 115. The rubbing roller 105 has a covering of resilient and porous foam 106 and rubs off the more soluble areas of the material. The developed material separates from the endless belt by roller 97 and passes through squeegee roller pairs 100-101 and 102-103 so that it is nearly dry when emerging through slot 92. Water or a mixture of alcohol and water may be used for development and the recording material may be of the type disclosed in Specifications 1,139,891, 1,160,221, and 1,154,902.
