Title: Improvements in or relating to apparatus for the spectographic chemical analysis of materials by means of photoelectric cells
IPC: G01J3/36
Filed: 1962-01-25
Abstract: 999, 670. Photo-electric spectro-chemical analysis. REGIE NATIONALE DES USINES RENAULT. Jan. 25, 1962, [Jan. 25, 1961], No. 2933/62. Drawings to Specification. Heading G1A. The invention relates to spectrographic analysis apparatus of the type in which electrical excitation of the test sample, for example by using it to form at least one electrode of an arc, is used and selected spectral lines from the radiation produced are directed to photo-cells for evaluation. Signals derived from reference radiations or internal standards are used in the evaluation and control integrating devices for the signals from the test sample photo-cells. Apparatus of this type is described in Specifications 912, 882 and 957, 201. According to the present invention signals derived from reference radiations are fed either through a D. C. amplifier to a measuring instrument to assist in the setting up of the apparatus or to an integrating capacitor for comparison with a preset voltage during operation. In the operating sequence equality of integrated reference photo-cell signals with the reference voltage causes the operation of a relay controlling a thyratron which terminates' the integration of signals from a test sample photo-cell. Specification 862,212 also is referred to.

Title: Sonic vibrator
IPC: B06B3/00
Filed: 1974-04-19
Abstract: 1466862 Ultrasonic agitation of liquids KERRY ULTRASONICS Ltd 19 April 1974 [19 Jan 1973] 2948/73 Heading B1C [Also in Divisions H2 and H4] A sonic or ultrasonic transducer (e.g. for ultrasonic cleaning) comprises a piezoelectric disc transducer element 4 held under compression between two metallic end sections 1, 2 such that, when the transducer is operated as a halfwave resonant extension mode transducer, the vibration node (or stress antinode) is located away from the piezoelectric material and its contacting surfaces. The face area of the end section 2 which, in use, operates into the load is greater than that of the disc transducer 4. As shown the vibration mode cuts the end section 2. The tolerances on flatness and finish required at the contacting surfaces need be no better than the oscillatory amplitude at these surfaces to achieve virtually 100% mechanical coupling under all conditions. Element 4 may consist of a single piezoelectric disc of two or more discs. One or more bolts 3 apply the compressor. The sections 1, 2 may be of different or the same material.

Abstract: 1,245,907. Making metal elbows and return bends; angular bending. R. J. LATHAM. 21 Jan., 1970, No. 2969/70. Headings B3A and B3E. A method of making metal elbows and return bends comprises making two substantially straight parts 1, 2 of trough or gutter-like shape from a strip or plate of stainless steel, bending the parts lengthways into a part circular shape in a tube bending machine to form inner and outer diameter parts, placing the parts together to form a part-circular tube, welding the parts together and finishing the tube to form an elbow or a return bend. The trough like part 1 is secured to a former 3 by a clamp 7 and a back bar 4 fits into the trough of the part 1. The back bar is engaged by rollers 9 mounted in a fixed support 9a. A turntable 6 is then rotated and as the clamp 7 is fast therewith, the part 1 is bent around the former 3 and wrinkling is prevented by the bar 4, which is carried along tangentially to the former. The outside diameter part 2 is formed in substantially the same way, with the clamp (7), former (10) and back bar suitably modified to form the concavity facing radially inwardly, Fig. 3 (not shown). A 180 degree return bend is formed, which may be used as such or cut to a required size.

Title: Improvements in or relating to production of chlorides of metals
Inventor: GIBSON ALLAN ROBERT
IPC: C01G43/04
Filed: 1952-02-05
Abstract: Anhydrous chlorides of beryllium, zirconium and uranium are produced by introducing one of the above metals into molten dry zinc or lead chloride or into a molten mixture of such a chloride and an alkali metal chloride, so as to effect a displacement reaction between the added metal and the lead or zinc chloride and thereafter separating the chloride formed from the displaced metal.  According to an example a mixture of lead chloride and potassium chloride (the latter having the effect of lowering the melting point), was heated to 500 DEG C. in an electrically heated silica vessel and dry inert gas was passed into the vessel to displace air.  With vigorous stirring beryllium flake was introduced into the mixture of molten chloride whilst maintaining the operating temperature at 500 DEG C.  At the conclusion of the reaction the melt was electrolysed between graphite electrodes under a potential difference of 2 volts until the chloride layer was lead free, after which that layer was removed to a sealed container and lead recovered from the residue.ALSO:Anhydrous chlorides of beryllium, zirconium and uranium are produced by introducing one of the above metals into molten mass dry zinc or lead chloride or into a mixture of such a chloride and an alkali metal chloride so as to effect a displacement reaction between the added metal and the lead or zinc chloride and thereafter separating the chloride formed from the displaced metal.

[Class 47 (ii)] [Also in Groups VI and [XII A solution of large quantities of carbon-dioxide in water, for fire-extinguishing purposes, is obtained by discharging water under pressure, by means of a perforated pipe 5, into a mass of carbondioxide ice contained in a jacketted vessel 2 provided with a manometer 10 and safety valve 11. The water is stated to gasify and dissolve the carbon dioxide, the resulting solution being discharged by a pipe 6 with a nozzle 7. In a modification, the vessel 2 is spherical with a perforated inner wall. Extinguishing media, such as sodium, calcium, magnesium, or ammonium chloride, alum, magnesium carbonate, infusorial earth, or ashes may be added to the carbon-dioxide ice or to the water. The Specification as open to inspection under Sect. 91 states also that the gas evolved by the slow sublimation of the carbon-dioxide ice may be collected and used for aerating liquids, preserving foodstuffs, or freezing water pipes to facilitate their repair, or for attacking fires at an early stage or providing an inert atmosphere in storage spaces for combustibles. It describes a plant for obtaining gas from solid carbon dioxide,. Fig. 5 (Cancelled) comprising a vessel 2 for carbondioxide ice with a water-supply pipe 4. The solution produced is passed by a spray pipe 14 into a vessel 15, where the water separates and is removed by a siphon 16. The gas is drawn by a fan 20 into a storage space 18 for combustibles 19. In an alternative plant, Fig. 6 (Cancelled), gas sublimed from the vessel 2 is collected in receivers 21. 22. Pipes 23 from the receivers 22 are connected to branch pipes 26 with nozzles 27. Water under pressure can be supplied to one pipe 26 by a pipe 28, so that a solution of carbondioxide in water can be discharged by the corresponding nozzle 27 for such purposes as fire-extinguishing or quenching coke. The other pipe 26 is connected to a storage place 18 for combustibles. This subject-matter does not appear in the Specification as accepted.

[Also in Division H1] A voltage controlled resistor comprises a discharge tube 5, a photo-resistor 2 and a screen 8. The tube 5 has filiform anode and cathode 6, 7 and is so designed that at the lowest voltage that will support a discharge the cathode glow extends along a length G1 and thus cannot illuminate the photo-resistor 2 directly, but only by diffusion. As the voltage increases the glow spreads over more of the cathode and more light falls directly on to the photo-resistor. In modifications the cathode may be longer than the anode, Fig. 2 (not shown) or the tube may be A.C. energized with the screen extending along only the middle of the tube 5, Fig. 3 (not shown). The characteristic of the resistor may be controlled by suitable shaping of the photo-resistor Figs. 4, 5 and 6 (not shown). A plurality of photo-resistors may be illuminated by one discharge tube.
