Title: Crystal growing
IPC: B01D9/02
Filed: 1972-04-06
Abstract: 1385234 Computerized crystal growth WESTERN ELECTRIC CO INC 6 April 1972 [7 April 1971] 15932/72 Heading B1G A synthetic crystal is grown from a seed crystal supported in an upper zone of an elongated vessel and a crystal growing nutrient solution provided in the lower zone of the vessel by applying heat to the upper and lower zones to establish a convective flow of dissolved nutrient over the seed crystal with a temperature gradient existing between the upper and lower zones and controlling the temperatures in the zones thereby controlling the rate of flow of the nutrient solution over the seed crystal. The temperature control conditions are obtained from an empirical formula which has been reduced to a finite number of steps and such steps as an algorithm are fed into a computer which automatically controls the temperatures in the two zones. Figure 1 shows a crystal growing apparatus 100, comprising a cylindrical autoclave 101 supported on fire brick 102 and set in a concrete pad 103. The autoclave is divided by perforated baffle 104 into two zones. In the lower zone the nutrient to be dissolved e.g. quartz is contained in a wire basket 106 whilst in the upper zone a wire rack 108 supports a plurality of seed crystals 109. In operation the interior of the autoclave contains aqueous media e.g. a solution of sodium hydroxide and one or more dopants e.g. lithium nitrate. Heating is provided by heater bands 112 and 113, and current supplied to these heaters can be individually adjusted by the magnetic amplifiers &c shown in Figure 15 and controlled by digital computer 142 which comprises a central processing unit 151, coupled to a memory storage device 152 and control circuit 153. The apparatus also includes a pressure sensing device 114 positioned in the autoclave via an aperture in threaded seal 111, to permit pressure monitoring during the crystal growing process. The temperature in the heater bands is monitored by thermocouples 116, 117, 118 and 119. The entire autoclave is enclosed in a thermal insulating jacket 122. In operation the temperature difference between the upper and lower zones is about 70F, and the pressure in the autoclave approximately 25,000 pounds per square inch. The apparatus is preferably used for the growth of quartz crystals but may be used for emerald, corundum (Al 2 O 3 ), berlinite (AlPO 4 ), calcite (CaCO 3 ), zincite (ZnO), tourmaline, magnetite, fluorite, scheelite, garnets and zircons.

Abstract: 515,478. Oven stoves. SMITH, J. L. May 28, 1938, No. 15966. [Class 51 (ii)] [Also in Group XI] An oven heated by gaseous or liquid fuel, electricity, steam, or hot water, is provided with a storage space 14, defined in the form shown by partitions 9, 9a, through which space air is blown by a fan 8, the air, when and after leaving the space 14 and before returning to the fan, flowing over a heating member in the oven. In the form shown, this heating member comprises finned or deeply corrugated walls 3, 5a which also bound flues 2, 5 for hot gases from a burner 4. The flue 5 ends in a chimney outlet 6 and an opening leading to the air-circulating space outside the partitions 9, 9a. This air-circulating space also has an outlet passage 11. A damper 7 can be operated to allow hot gases to enter the air-circulating space and at the same time to close partially or completely the flue 6, and is linked to a damper 12 in the flue 11, so that as one flue is closed the other is opened. The flue for the hot gases may be arranged within the air-circulating space above the partition 9, so that the air passes all around it.

Valve means (piston 24) urged against the action of a spring by the suction in the induction pipe downstream of the throttle valve 3 restricts, in response to an increase in suction, downstream of the auxiliary starting carburetter distributing valve 15 the passage through which the fuel or mixture supplied by the auxiliary starting carburetter is fed, this passage being located upstream of the junction with the air passage. As shown the passage includes two channels 29, 30 and the piston closes the channel 29 when the suction increases as a result of the engine having been started. The distributing valve which may be operated manually or automatically as by a heat sensitive device comprises a radial groove 31 communicating with a central recess 32 which recess communicates through a small hole 33 with, a groove 34. An air inlet orfice 35 opens into the groove 34. Conduit 11 opens into the face 18 through several for instance two holes one of these holes being in direct communication with the conduit 11 whereas the other hole 20 communicates with the conduit 11 through a channel 21 of small cross-section. As the engine is warming up the valve 15 is rotated either into an intermediate position Fig. 4 or to an inoperative position. In the intermediate position a lower proportion of fuel is supplied since the groove 31 is opposite the orifice 20 which communicates with the conduit 11 only through the small passage 21. The upper end of a channel 37 may be located either on the outside of the carburetter or on the portion of conduit 12 upstream of the piston. Conduit 10 communicates with the well 8 through one or several holes. The air inlet 13 preferably communicates with the air intake 14 downstream of an air filter. Specification 708,526 is referred to.

Patent GB-1048805-A (GB)
Title: Clothes washer machine
IPC: D06F34/08
Filed: 1965-04-15
Abstract: A horizontal drum washing machine has a tub-drum unit mounted on a platform supported on rubber block shock-absorbers and has an electric vibration-responsive switch which when operated by excessive vibrations of the drum reduces the speed of the motor. Vertical and lateral vibrations are checked by resilient mountings between the cabinet and the baseplate of the washing unit Fig. 8 (not shown) and angular vibrations are absorbed by shear stresses in the pads, 98, 100 (Figs. 6 and 7, not shown).  A timer motor rotates a series of cams to produce a cam switch operation for the washing sequence. During high-speed rotation for spin drying if the drum is unbalanced the switch is operated which intermittently de-energizes the drive motor and so reduces the drum speed to redistribute the clothes.

Title: Improvements in the manufacture of halogenated olefinic hydrocarbons
IPC: C07C17/158
Filed: 1943-10-08
Abstract: Olefinic halohydrocarbons containing 2 to 4 carbon atoms and at least one hydrogen atom are reacted with oxygen and chlorine, hydrochloric acid, bromine or hydrobromic acid in the presence of an oxydation catalyst at a temperature of 200-600 DEG  C. for chlorine and bromine and 250-600 DEG  C. for hydrogen chloride and hydrogen bromide to produce an olefinic halohydrocarbon of higher halogen content.  In the examples (1-3), vinyl chloride, unsymmetrical dichloroethylene and symmetrical dichloroethylene respectively are mixed with hydrogen chloride and air and passed over a heated catalyst consisting of copper oxide supported on firebrick.  In example (4), vinyl chloride is introduced into the end of a heated reaction tube packed with firebrick impregnated with cuprous chloride.  Chlorine and air are introduced in five increments, through inlet tubes along the reaction tube.  The products are recovered in all cases by refrigeration, followed by fractional distillation.  Other methods such as compression and cooling, or scrubbing with scrubbing liquids, may also be used for recovery.  The reaction will proceed with practically any oxydation catalyst, such as metals, or metal compounds like oxides or salts, e.g. oxides or compounds of copper, iron or bismuth, metallic copper, zinc oxide, barium oxide, alumina, various rare earth oxides, magnesium oxide, manganese oxide, silver oxide, titanium dioxide, lead oxides, cobalt oxides, nickel oxides, magnesium sulphate and molybdenum dioxide.
