[Also in Divisions F2, G2 and G3] Automatic analysis apparatus comprises a loop conveyor having at least one row of openings to receive open-topped containers 24, means for indexing the conveyor, means for dispensing samples to be tested into the containers at a dispensing station, means for dispensing reagents into the containers at a reagent dispensing station, means for heating the containers containing sample and reagent at a reaction station, means for testing the contents of the containers at an analysing station, means for cleaning the containers after the testing, and automatic control means for actuating the conveyor indexing means, the sample and reagent dispensing means, the testing means, the cleaning means and the drying means and controlling the sequence of operation. The conveyor with the means for heating, cleaning and drying the tubes is the subject of Specification 1,240,305. Operation of the conveyor &c by piston-cylinder device (156) (Fig. 34, not shown) with an air supply controlled by master timer (272) continues until the last of the programmed tests is completed, when to end the cycle an end wash timer is actuated and this continues to index the conveyor for a predetermined number of cycles to ensure cleaning of all the tubes 24. The sample dispensing assembly (Fig. 7) comprises a pick-up needle (62) (Fig. 8, not shown) carried by car 64 movable along arm 66 which itself is rotatable about one end to move needle (62) to a position over a sample container 46 on turntable 32, which may be mounted over a cooling jacket 50, then back over a row of tubes 24 on the conveyor, car 64 travelling along arm 66 to dispense aliqnots of sample into each container in the row. The samples in each longitudinal row of tubes on the conveyor may be subjected to the same test. The sample pick-up and dispensing device is the subject of Specification 1,240,304. The reagent dispensing assembly (Fig. 35), which is the subject of Specification 1,240,306, comprises piston-cylinder device 280,278 and one-way valves 282, 284. Reagent is withdrawn from container 38 through valve 282 into the cylinder and forced out of the cylinder through valve 284 under air-pressure. The reagent dispensing lines for a row of tubes 24 on the conveyor pass through holes in a bar 334 mounted transversely over the conveyor. At the analysing station the contents of a row of tubes 24 are simultaneously aspirated into a row of cuvettes for optical measurement. The operations to be carried out on each sample are preselected by pressing buttons on a control panel (Figs. 1, 62, 64 not shown). The control means is the subject of Specification 1,240,308.

Title: System for controlling radiation intensity of welding arc
IPC: B23K9/073
Filed: 1964-12-24
Abstract: 1,030,559. Automatic control systems for welding. WELDING RESEARCH Inc. Dec. 24, 1964 [Dec. 27, 1963], No. 52406/64. Heading G3R. The position of a non-consumable welding electrode relative to a work-piece is automatically controlled so that the radiation intensity of the arc is maintained constant. A radiation detector responsive to ultraviolet or infra-red radiation produces a voltage for comparison with a reference voltage, the resulting error signal being applied over integral and proportional amplifiers to driving means for positioning the electrode in dependence upon variations in radiation intensity. The arc is first ignited by the application of high frequency oscillations, and the positioning control system initially is responsive to voltage variations across the arc; at a predetermined time after starting relays operate to switch the system over to control by radiation intensity. The control voltage for the system is derived from a transistor circuit connected to the radiation sensing means which may include a photo-diode associated with a bundle of glass-fibres which transmit the radiation from the arc to the diode.

Abstract: 1459995 Treating enamel coatings BRITISH GAS CORP 15 Feb 1974 [20 Nov 1972] 53567/72 Heading C1M A method of treating vitreous enamel, in the form of a coating on a substrate, comprises decomposing a compound comprising at least one metal ion, the metal ion being such that when incorporated into the enamel surface it improves the microhardness of the surface (measured by the Vickers method) by at least 10%, the compound being decomposed to the corresponding metal oxide in or on the enamel surface to increase the surface strength and hardness. The metal ion may be Sn, Cu, Ni, Al, Co, Ce, V, Mn, Zr, Ti or Zn, and the compound preferably decomposes at 200-800‹ C. In one embodiment metal halide vapour (e.g. a halide or Cu, Al or Sn) is introduced into a furnace in which it decomposes to the oxide, which is deposited on the enamel. Alternatively, the enamelled article may be immersed in a solution or dispersion of an organo-metallic compound, removed and drained, and heated to decompose the organometallic. Also, a pre-heated enamelled article (e.g. at 400-800‹ C.) may be sprayed with a solution or dispersion of the organo-metallic, the compound pyrolysing to form the oxide on contacting the surface. Also, an enamelled article may be sprayed with organo-metallic and the surface then subjected to oxidation. The organometallic compound may be diisopropyl triethanolamine titanate, or an alkyl titanate, vanadate, zirconate, stanate, zincate or aluminate. The vitreous enamel preferably is one which has been fired at 700-850‹ C., or a titania-opacified white enamel. The invention may be used in providing an improved enamel coating on gas ovens or cookers. A wax coating (e.g. polyethylene wax, silicone wax or carnuba wax) may be provided over the enamel.

[Also in Division F1] An aerosol fluid dispenser comprises a release valve and a measuring chamber 2a which is adjustable in volume to enable the volume of fluid discharged at each operation to be predetermined. The chamber 2a is formed in a housing 2 which is slidable on a gasket member 7 clamped to an aerosol container 1 by means of a cap 6. The housing 2 may be raised or lowered by means of a lever, cam or screw device in order to vary the capacity of a reservoir 2c in communication with the chamber 2a. A valve (4, Fig. 1) is slidably mounted in the chamber and is arranged normally to allow the reservoir 2c and measuring chamber to fill with fluid. Upon depression of the valve 4 a hole (11) therein is moved within the chamber 2a thereby allowing the fluid to be dispensed. In a modification the dispenser may be a separate unit adapted to be fitted to the valve of a normal aerosol container. In the embodiment shown in Fig. 4, the housing 2 is formed with a number of reservoirs each having a different capacity and each communicating with the chamber 2a through a port 25, all the reservoirs normally being filled. To discharge a selected reservoir the valve 4 is rotated to bring hole 11 into alignment with an outlet port 26 in the selected reservoir and then by depressing the valve the fluid is dispensed.
