Abstract: 1,153,323. Generators operating by electromagnetic interaction with fluids. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 11 Aug., 1967 [12 May, 1966], No. 21068/66. Heading H2A. An MHD generator has electrodes formed of a plurality of insulated segments 1, 2, 3, each connected to a common conductor CD through a capacitance 4, 6, 8 shunted by a resistance 5, 7, 9 having values which are chosen so that in operation any arc 12 which is formed is quenched or transferred to an adjacent segment. The arc 12 is formed in the boundary layer 10 between the electrode surface and ionized plasma stream 11 and causes capacitor 6 to be charged so that the arc is either extinguished or transferred to an adjacent segment and the capacitor is discharged through resistor 7. The circuit elements may be lumped and formed by the inherent characteristics of the electrode material. In specific embodiments the electrodes may comprise spaced sheet metal plates mounted on a thin ceramic layer which is deposited on a water-cooled metal substrate, Fig. 3 (not shown). Alternatively, a thick ceramic coating is provided on the metal substrate and the segmentation provided by deep grooves, Fig. 4 (not shown). In a further example, a series of watercooled metallic blocks are used, insulated from each other by properly chosen ceramic material with the blocks that are connected to the common conductor recessed from the working surface of the electrode, Fig. 5 (not shown).

Abstract: 619.218. Knitting-machines. CORAH & SONS, Ltd., N., and BREWIN, A. Aug. 21, 1945, No. 21301. [Class 74(ii)] A stop motion or thread regulating device for a knitting-machine or other textile machine comprises two movable bridging contacts located within a compartmented casing and adapted to swing into two volumes of conducting liquid under the influence of a thread detector projecting through the casing, when the yarn breaks, becomes slack, or is excessively tensioned. As shown, a casing 1, Figs. 1 and 2, is divided into two compartments 1a, 1b, containing globules of mercury 3a, 3b in contact with terminals 4a, 4b extending through the casing to a terminal and a back plate 9 respectively. Holes 6 in the outer side walls of the casing form bearings for spindle portions 7 of a dropper 11, the lower arms 8a, 8b of which depend into the compartments 1a, 1b respectively. On breakage or slackening of the thread T, which passes between the dropper 11 and a comb 13, the dropper falls and the arms 8a, 8b swing into contact with the mercury to complete the circuit and stop the machine. Stoppage may also be brought about, when the thread is tensioned excessively, by supporting the comb at 15 for pivotal movement against the action of a spring 16, the accompanying downward movement of the dropper 11 .causing the arms 8a, 8b to contact the mercury. The closing of the switch is arranged to energize a relay coil 20, Fig. 3, not shown, and release a latch which effects stoppage or other change, such as displacement of the stitch cam, and simultaneously moves a trigger to operate a circuit breaking switch.

Abstract: 732,814. Cracking gaseous mixtures; oil gas. HASCHE, R. L. July 31, 1953 [Oct. 2, 1952], No. 21306/53. Class 55 (2). [Also in Group XIII] . A gas interchangeable with town gas is produced in a regenerative furnace comprising two regenerative masses 3, 4, each in a separate chamber, and a connecting chamber 6 containing a burner 11. The contiguous ends of the masses 3, 4 are heated to 1000‹ F. by burner 11. A gaseous mixture of air and hydrocarbon is then passed through pipe 9 to mass 3, the amount of air being controlled to provide by combustion of a portion of the starting hydrocarbon sufficient heat for the endothermic alteration of the remainder of the starting hydrocarbon. The gaseous mixture is heated in passing through mass 3 and partial combustion and endothermic alterations take place in chamber 6, the hot gases from which pass through and heat up mass 4, and are thereby cooled. At the same time mass 3 is becoming cooler and eventually it becomes necessary to reverse the flow through the masses so that mass 4 is giving up heat and mass 3 is receiving heat. Alternatively, an intermittent process may be operated, in which the furnace is brought to operating temperature and is heated up at intervals, during which time the production of gas is stopped. Specifications 697,108, [Group XIII], 699,318, 705,393, and 716,814 are referred to.

Abstract: 1317683 Measuring porosity electrically ALUMINIUM SUISSE SA 19 April 1971 [17 Feb 1970] 21931/71 Heading G1N The porosity of a dielectric layer (e.g. a corrosive protective layer) on a metallic surface e.g. container 8 is determined by covering the layer with an electrolyte containing an electrophoretic varnish and applying an e.m.f. between electrode 2 and the metallic surface 8 to cause electro-deposition of a non-conducting component of the varnish on those parts of the surface 8 adjacent to pores in the dielectric layer. Since the quantity of current consumed is directly proportional to the quantity of material deposited which is, for a given thickness of deposit, proportional to the surface area of the pores, a measure of the quantity of electricity used gives an indication of the porosity of the dielectric layer. Time switch 3 enables the voltage from stabilized source 1 to be applied for 10 secs. and the current consumed during this period measured by means of shunt 4 and integrator 5 including a display device 6. Instead of the metallic surface being a container or flexible or rigid can or tube it may be a planar surface. The varnish may be colored to show the position of the pores.
