Abstract: 263,194. Scheidhauer & Giessing Akt.-Ges. Dec. 19, 1925, [Convention date]. Refractory substances containing kaolin; rendering non-plastic materials plastic. - In the manufacture of refractory, acid-proof, and other ceramically bonded articles from non-plastLc materials such as grog, fused alumina, corundum, sillimanite, carbides, zirconium compounds, chromium oxide, magnesia, silica, &c. these materials are mixed with an alkaline kaolin slip in such proportions that a non-castable mass results. This is moulded by beating, stamping, or pressing into articles which are then dried and burnt or in some cases used without burning for furnace linings, &c. A portion of the non-plastic material may be added during the preparation of the kaolin slip. When the slip is to be used in small proportions it may be diluted for admixture with the other materials, the excess of water being subsequently removed before moulding. Instead of kaolin a colloidal slip prepared by adding an electrolyte to pure alumina or aluminium hydroxide may be used. Specifications 253,947 and 262,383 are referred to.

Abstract: 877,430. Washing-machines. HOOVER Ltd. Oct. 17, 1957. No. 32523/57. Class 138 (2). [Also in Group XXXVII] An automatic combined washing-machine and spin-drier includes a combined washing and centrifuging basket mounted to rotate within a stationary container, a scavenging pump serving to pump liquid out of the container, means for driving the basket and pump, and timing means for timing a complete washing and drying cycle including at least one emptying period and at least one spin-drying period, in which level responsive means operate when the level falls below a predetermined high level during any emptying period, and then automatically render the timing means ineffective. As shown, main supply 180 reaches bus-bars 181 and 182 by way of cam-controlled contacts 171 and 172, the pump 145 for emptying the machine being controlled by pump motor 146. Supply to secondary bus-bar 184 can be interrupted by contacts 183 which are opened when the door of the machine is opened and stop main motor 70. The agitating impeller 31 is controlled by solenoid 116 and contacts 173. The timer motor 170 can be connected to busbar 182 either by way of " closed when empty " level responsive switch 1.51 or by way of contacts 171 and " closed when full " contacts 186 of level responsive switch 152 and thus the timing of the cycle of operations is always interrupted when the machine is filling or emptying. Also, if the level of liquid in the machine rises during a spin-drying phase, contacts 151 open and de-energize motor 170 and spin-drying control solenoid 106 so that both the timer and the spin-drying stop until the machine is emptied. The hot and cold water supply are controlled by solenoids 138 and 139 which can only be energized when " closed when not full contacts 187 of level responsive switch 152 are in the closed position shown. A " hot-automatic-cold " switch is provided with contacts 191 to 196 arranged so that, in the " auto " position, only the hot water valve is opened during the initial filling period and during a subsequent filling period both valves are opened, in the " hot " position only the hot valve is opened and in the " cold " position only the cold valve is opened during any filling period. The machine is the same as is described in Specification 877,429. Specifications 612,737 and 624,191 also are referred to.

Abstract: 537,518. Velocity-modulated tubes. STANDARD TELEPHONES & CABLES, Ltd., and FREMLIN, J. H. Dec. 22, 1939, No. 32814. [Class 39 (i)] [Also in Groups XXXV and XXXVI] A resonator of the hollow type for use with electrondischarge devices, employing velocity modulation, such as that described in Specification 537,490, is corrected for changes in capacity produced by changes in temperature. Fig. 1 shows such a resonator A in which an electron beam is velocity modulated in the space between the pairs of plates E and D and returns energy to the resonator in the space between the plates C and D. To correct the capacity for changes of temperature the plates C are made of material of low coefficient of expansion and are carried by fins L projecting from the body of the radiator and attached to the plate C at their outer ends. In a modification two other resonators are provided, made of material of low co-efficient of expansion and having periods slightly above and below that of the resonator A. When the period of the resonator A becomes equal to that of one of the auxiliary resonators through changes in temperature the oscillations produced in that resonator are rectified, amplified and employed to correct the capacity of the resonator A. This may be done by moving the plates C, either by means of bimetallic strips heated by the current, by magnetic coils, or by piezo-electric crystals.
