Patent GB-676212-A (GB)
Title: Improvements in or relating to methods and apparatus for growing crystals
Inventor: WARNER ARTHUR JAMES
IPC: C30B7/00
Filed: 1949-02-14
Abstract: <PICT:0676212/III/1> In a process for growing single crystals by circulating nutrient solution between a dissolving tank 1 and a growing tank 13 maintained at constant, different temperatures, solute is added substantially continuously to the tank 1 from hopper 51 and the rate of addition is automatically controlled to maintain the concentration in the tank substantially constant.  The temperature in the dissolving tank is maintained at least 1 DEG C above that at which the solution would be saturated.  As described pump 12 draws solution from tank 1 through filter 8 and viscosity meter 10 and delivers it to the bottom of container 13. Increases and decreases in viscosity (and hence concentration) are used, (see Group XXXV), to decrease or increase the rate of addition of solute from the hopper 51.  The containers 1, 13 are heated by electrical jackets 2, 14 and the temperatures are thermostatically controlled. Connecting pipes 11, 17 are also heated.  Seed crystals 23 are carried by a spider 22 in container 13, the spider being rotated first one way and then the other by suitable means.  Instead of viscosity any other parameter, e.g. density, dependent upon concentration may be used to control the addition of solute. Alternatively the rate of addition of solute may be preset in accordance with the rate of crystal growth as determined over the entire growing period by experiment.  The crystallization of ethylene diamine tartrate is referred to using a solution which would be saturated at 45 DEG C with a temperature of 50 DEG C in the dissolving tank and of 42.5 DEG C in the growing tank.

Abstract: 1,071,278. Electrophysical measurement. SOUTH AFRICAN INVENTIONS DEVELOPMENT CORPORATION. Feb. 1, 1966 [Feb.12, 1965], No.4362/66. Heading G1N. [Also in Division H2] Apparatus for warming blood wherein the blood is warmed by an induction heating device comprises means whereby the change of impedance of the blood due to its rise in temperature is effective to terminate the heating when the blood has reached the desired temperature. Blood 6 contained in a flask 5 is placed in a receptacle 46 wherein is situated an induction heating coil 2, the presence of the flask 5 in the receptacle 6 causing the closing of a switch in the power supply to the apparatus, which supply may be rectified alternating current. The heating coil 2 forms one arm of a bridge circuit, other arms of which comprise resistors 8-12 the resistor 10 being variable to set the desired final blood temperature. The heating coil 2 is fed by way of an oscillator including a thermionic valve or semi-conductor device 1 and variable capacitors 3, 4. As the blood 6 warms its resistance decreases thus increasing the load on the oscillator which unbalances the bridge circuit until, when the blood has reached the set temperature, the unbalance is sufficient to energize a relay coil 14 across the bridge diagonal whereby to terminate the heating, an indicator 13 registering the temperature of the blood. A short circuited turn 47 spaced from the heating coil 2 is provided around the neck of the flask 5 so as to provide a sharp definition of the magnetic field produced by the coil 2 and prevent over heating of the blood at the surface of the flask. Various safety devices and indicating lamps are provided and the preferred operating frequency of the oscillator is between 30-35 megacycles per second.

Filed: 1954-02-15
Abstract: 747,285. Feeding webs. POWERS CHEMCO, Inc. Feb. 15, 1954 [May 14, 1953], No. 4417/54. Class 100 (1). A web feed mechanism includes a hollow perforated roller over which web material is passed, means for maintaining the web material in contact with the hollow perforated roller by suction applied through the apertures, and means for reducing or substantially eliminating suction through those apertures not covered by the material. As shown, a hollow, cylindrical feed roller 10, Fig. 1, has a shell 11 provided with apertures 12 arranged in groups, such that a web 40 passing around the roller 10 is caused to adhere to the roller 10 by suction. The apertures are preferably arranged in groups of four apertures, in which case each group communicates with a chamber 16, Fig. 4, formed by recessed strips 14 attached to the inner surface of the shell. Each chamber 16 has a passage 18 leading to the interior of the roller which communicates with a source of suction. The passage 18 is closed by a reed 20, such as a metallic leaf spring, when the corresponding apertures 12 are uncovered by reason of the large initial flow of air through the passage 18. A bleed hole 22 in the reed 20 permits a very restricted flow of air into the roller, causing the reed 20 to spring away from the passage 18 when the corresponding aperture 12 becomes covered by the web. Alternatively, the bleed hole 22 may be replaced by grooves in the seating surface of the reed 20 or the strip 14 to provide bleed passageways.
