Title: Photo-oxidation sterilization
IPC: A61K35/14
Filed: 1974-04-02
Abstract: 1432095 Photo-oxidation sterilization BAYLOR COLLEGE OF MEDICINE 2 April 1974 [16 April 1973 26 Dec 1973] 14537/74 Heading C1C [Also in Divisions A5 and C5] A photo-oxidation process for sterilizing liquid contaminated with organisms comprises: sensitizing the organisms by adjusting the pH of the liquid to basic, intimately mixing from 0À1 to 100% by wt. of a photo-reactive dye with the liquid, exposing the water-dye mixture to a light of wavelength and intensity sufficient to excite the dye thereby inactivating the organisms. The process is suitable for treating liquid wastes, e.g. sewage, water, oil contaminated with water, oil-water mixtures or a biological. The dye may be removed after exposure to light. A photo-oxidation treating system is also claimed. This comprises a conduit, means for introducing influent and injecting a base into the conduit, means for mixing base and influent, means for injecting a dye into the conduit and into the influent, mixer means for mixing the influent and the dye to form a water-dye mixture, a chamber downstream of the mixer means and connected to the conduit, a photooxidizing light in the chamber having a wavelength and intensity sufficient to excite the dye, a discharge conduit extending from the chamber whereby the water-dye mixture flows through the chamber and into exposure with the photooxidizing light, and is discharged from the chamber. In Example 1 raw sewage was treated with a cation resin exchanger (not charged) to remove divalent cations, treated with methylene blue (1% by wt. at pH 10À5 and 37 C. for ¢ hour). It was then exposed to a photo-oxidizing light for 30 sees. The treated product did not contain any detectable microbiological flora. In Example 2 sewage containing added viruses was treated so that these were removed.

Title: Improvements in or relating to thermostatic electric switches
IPC: H01H89/04
Filed: 1934-05-15
Abstract: 438,372. Thermal switches. BRITISH THERMOSTAT CO., Ltd., Windmill Road, Sunbury, Middlesex, and PAYNE, M., 50, Hook Road, Surbiton, Surrey. May 15, 1934, No. 14691. [Class 38 (v)] A thermal switch with additional manual operation comprises a coiled bimetallic strip 1 connected at its inner end to a pillar rotatably mounted on the base 3 and having connected to it a lever 15 the slotted end of which is engaged by an eccentric pin 14 on a knob 12 which can be rotated to vary the temperature setting of the switch. The free end of the bimetallic strip carries a contact arm 5 having spring - mounted contacts 6, 7 adapted to engage respectively fixed contacts 8 and 9. Horseshoe magnets 10 co-operate with armatures 11 to give a snap action. The operation can be modified by manual means which comprise a knob 19 rotatably mounted on the base and which has a lower octagonal part co-operating with a spring 23, and has two pins 21 adapted to engage the free end of the arm 5. In the position shown the pins 21 do not engage the arm 5 which is entirely under thermal control. If the knob is rotated through 45‹ it is held in position by the spring 23 engaging one of the flats 22 and one of the pins 21 lies in the path of the arm 5 preventing it from engaging the corresponding fixed contact while leaving the other contact under thermal control. Rotation of the knob through nearly 90‹ forces the arm 5 into engagement with one of the fixed contacts and is held by the pressure of the spring 23 tending to rotate the knob farther. Thus either of the circuits can be operated manually or either can be rendered ineffective.

Abstract: 423,004. Converting. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. May 16, 1934, No. 14803. Convention date, May 22, 1933. [Class 38 (ii)] In an inverter arrangement employing discharge devices having auxiliary anodes for maintaining the arc the supply to the auxiliary anodes is displaced in phase with respect to A.C. output by means of chokes in the auxiliary anode circuits, which are interlinked in such a way that no resultant D.C. magnetization is set up. Since the main current in each half cycle falls to a value which is insufficient to maintain the cathodic spot, the phase of the A.C. supplied to the auxiliary anodes is displaced so that the peak of the auxiliary anode current occurs when the main current is low, thus preventing the cathodic spot from going out. The auxiliary anodes 3<1>, 3<11>, are fed from a secondary winding on the main transformer through interlinked chokes 71, 7<11> which shift the phase of the current approximately 90‹. In addition, the core of the chokes is designed to saturate so as to give a peaked wave-form to the current.

The normally-open contacts RCO of a relay RC (which may be used to control a variable) are cycled on and off at a predetermined rate by means of a transistor T3 which varies the relay coil current between its energizing and drop-off values according to the charge and discharge of a capacitor C2 produced by the opening and closing of further relay contacts RC1 operable simultaneously with the contacts RCO. Such opening and closing of the contacts RC1 alternately cuts off and makes conductive a transistor T2 whose base is additionally supplied with an A. C. signal voltage derived from a bridge B, transistor T1 and capacitor C1, so that the "on" and "off" times of the relay contacts are varied in accordance with the magnitude and sense of the signal, the circuit parameters being chosen so that the signal is ineffective when the emitter voltage of transistor T2 is changing positively. The contacts RCO may control an electric furnace whose temperature is sensed by a resistance thermometer or thermistor connected in the bridge B. The contacts RC1 may be replaced by an electronic switching means deriving control signals from the voltage across the relay coil RC. The various time constants of the circuit and the impedance of the transformer winding W2 are chosen so that members T3, RC operate with a snap-action.
