Title: Spigot and socket pipe joints
IPC: F16L21/025
Filed: 1977-04-01
Abstract: The sealing of pipe plug-connections, in particular for pipe elements consisting of inorganic material, is made more difficult because such pipe elements have relatively large manufacturing tolerances, most of them are not precisely round and, due to their high weight, load a sealing ring non-uniformly. The sealing ring therefore has a virtually V-shaped cross-sectional profile, the two legs of this profile being designed as ring lips (1, 2), of which one (1) is provided for resting on the inner wall (9) of an outer pipe end (10), while the other (2) projects inwards in a virtually radial direction. On insertion of an inner pipe end (14), the ring lips (1, 2) of the sealing ring, manufactured from flexible material, pivot about the connecting region, designed as a seal foot (3), of the two ring lips, and the sealing ring rests, with the free ends of its two ring lips, on the outer surface (15) of the inner pipe and, with the seal foot, on the inner surface of the outer pipe. In this manner, effective sealing of the pipe plug-in connection can be achieved with respect to both internal pressure and external pressure. <IMAGE>

Title: Improvements in installations including remote control transmissions, for the selective protection of electric networks
IPC: H02H3/30
Filed: 1946-05-14
Abstract: 631,729. Protective systems. UNION D'ELECTRICITE. May 14, 1946, No. 14580. Convention date, May 18, 1945. [Class 38(v)] [Also in Group XXXIX] Phase shift compensation is provided in a selective protective system employing carrier currents such as those described in Specifications 631,725 and 631,726, which is controlled by a comparator BC receiving voltages UA, UB in phase with currents IA, I<SP>B</SP> at two points in the line. One of the voltages is transmitted over the power lines as a doubly modulated carrier from a transmitter E, modulated by audio-frequency oscillators 0, : 3  working at three separate frequencies between 1000 and 2000 c.p.s., each of which is itself modulated at power frequency by the current transformers. The de-modulated signal from the first detector DHF is separated by three audiofrequency filters F 1  : 3  each of which is followed by a power frequency detector DBF and amplfier Am. During transmission de-phasing occurs firstly at the audiofrequency filters which have a time constant of 3 or 4 milliseconds, corresponding to a lag of 54‹-72‹ cycles, and secondly at the filters in the amplifier which are necessary to smooth out parasitic disturbances due to switching on in other parts of the line, resulting in a total lag of about 126‹. To compensate for this a de-phasing unit Dp, of inductances and condensers is connected either between the amplifier and comparator ,(as shown) to bring the total phase shift to 180‹, and the leads to the comparator are reversed, or between the transformer TA and the comparator to produce an equivalent lag 126‹ so that both voltages arrive at the comparator in phase Fig. 4, (not shown). The latter connection is stated to be preferable as both input circuits have the same time constant, whereas in the former connection giving 180‹ phase shift a time lag of about 10 milliseconds between the voltages arriving at the comparator will occur in a case of reversal of current at both ends of the section due to a fault in adjacent line section, Fig. 3, (not shown). This may cause incorrect operation with a high speed comparator .
Patent GB-417075-A (GB)
Title: Improvements in or relating to the purification of sugar factory and refinery juices
IPC: C13B20/02
Filed: 1933-05-19
Abstract: Sugar factory or refinery juices are purified by adding lime or equivalent alkali, and if necessary sulphur dioxide or an electrolytic equivalent in amounts sufficient to bring the juices to the optimum isoelectric point in the alkaline range of the colloidal impurities to be flocculated, adding a small amount of lime or equivalent alkali so that the soluble alkalinity of the juices is an optimum for the subsequent removal of the flocculated impurities, heating the juices to the flocculating temperature and, after separating the flocculated impurities, treating the juices with carbon dioxide or sulphur dioxide in order to reduce the alkalinity to factory requirements, defecation by further addition of lime being dispensed with.  After the juice has been brought to the optimum isoelectric point, which is defined as that at which the conditions of pH and alkalinity are such as to render the total amount of colloidal impurities flocculated a maximum, test of the soluble alkalinity may be made to determine the amount of lime or equivalent alkali required for the next step.  Details of the tests employed, quantities of lime required, definitions of the expressions "sulphur dioxide or electrolytically equivalent substance," "lime or equivalent alkali," and "factory requirements" are included.  The optimum isoelectric point lies between pH values of 10,6 and 12,0, and the flocculating temperatures in general lie between 80 and 95 DEG  C. for beet sugar juice.  Dilute sulphuric acid and phosphorus pentoxide are included among the electrolytic equivalents of sulphur dioxide. The sulphur dioxide may be added in liquid form or as a gas under relatively high pressure.  The carbon dioxide employed may be obtained from boiler flues.  The scums obtained by clarification of the juices with sulphur dioxide, carbon dioxide, phosphoric acid or other acid are added to other juices from which the impurities have not been removed.  The removal of the flocculated colloids may be effected either by filtration, centrifuging, or decantation. Examples are given.  Specifications 351,160 and 394,498 are referred to.
