Abstract: 1424402 Diesters of substituted methane phosphonic acids CIBA-GEIGY AG 28 March 1973 [4 April 1972] 14936/73 Heading C2P [Also in Division C3] Novel compounds of the general formula wherein Z is a divalent hydrocarbon radical which is necessary to complete a 5- or 6- membered ring and R 1  and R 2  are alkyl or alkenyl groups which can be substituted or together represent a C 2 -C 5  alkylene group are obtained by converting a compound of formula in which X is a radical which can be converted into the 1,2-epoxyethyl group into a compound in which X is a 1,2-epoxyethyl group. X in compound II may be a 2-halo-1-hydroxyethyl group in which case the conversion to the epoxyethyl group is carried out in the presence of an agent which splits off hydrogen halide, e.g. a strong alkali. The radical X in compound II may also be an ethenyl radical which may be converted to the epoxyethyl radical by means of a peroxy compound, e.g. by reaction with H 2 O 2  or a per-acid, e.g. peracetic, perbenzoic or monoperphthalic acid. The compounds II may be obtained by reacting a compound of the general formula with an epihalohydrin in the presence of a catalyst such as a tertiary amine or a quaternary ammonium salt or base, e.g. a quaternary ammonium hydroxide, and the product then converted directly to the product I in the presence of an agent which splits off hydrogen halide. The products (I) are useful as flameretardant agents for plastics materials, e.g. epoxy resins or polyurethanes.

Title: Improvements in or relating to apparatus for maintaining a predetermined level of molten metal in a continuous casting mould
IPC: G01F23/24
Filed: 1963-04-17
Abstract: 966,834. Automatic level control. GEB. BOHLER & CO. A.G. April 17, 1963 [April 19, 1962],No. 15010/63. Drawings to Specification. Heading G3R. The rate of feed of molten metal into the mould of a continuous casting mould is automatically controlled to maintain a predetermined level by controlling the rate of feed in dependence on the presence or absence of an electric spark discharge across the gap between the metal surface in the mould and a fixed electrode which is supplied from a source current-limited to make the arrangement shock-proof. As described high voltage is applied from a transformer the secondary of which is connected between the metal and an electrode so positioned above the metal that sparking just occurs when the level is correct. A series resistor limits current to a humanly safe value. Increase or decrease of the current with rise or fall in the level automatically produces correction of the rate of feed of molten metal. Specification 812,053 is referred to.

Title: Application of films
IPC: H01J9/04

Abstract: 1,006,422. Coating with preformed sheets. SYLVANIA ELECTRIC PRODUCTS Inc. April 19, 1962 [April 19, 1961], No. 15320/62. Heading B6G. A film including a soluble binder is applied to an object having a relatively cool surface by subjecting both film and object while in contact to a relatively hot vapour containing a solvent for the binder until the film has attached itself to the object. The process is particularly applicable to the application of electron emissive materials to a cathode base. The emissive film may comprise the alkaline earth carbonates and a binder such as ethyl cellulose, and suitable solvents are ethyl acetate and "Pentacetate," a mixture of isomeric amyl acetates. As shown, the solvent is charged to a vaporizing tank 10, the vapours being led via conduit 16 to a chamber 30 having a drainage bottom 32 leading to a solvent recovery tank (not shown). Both the vaporizing tank and the chamber are provided with thermostatically controlled heating circuits. A small opening 46 in the bottom of the chamber permits the introduction of a cathode base and an emissive film or a base to which a film has been imperfectly applied. An indexible conveyer 50 moves beneath the opening 46, the conveyer having recesses 52 to accommodate the ends of the cathode and a cross-bar 54 within each recess to prevent the cathode falling through. A transfer fork 60 having tines 62 and 64 which straddle the bar 54 rises through the aperture 52, engages the lower end of the cathode and carries the cathode into the chamber through the opening 46. The process is applicable to the proper wrapping of a film which is in part attached to a cathode, or to the attaching of a film when the film and cathode are in contact but unattached. Further, the film and cathode base may be subjected to vapour treatment before being brought into contact. Specification 1,006,426 is referred to.

Class 64(3) A heat exchanger comprises a plurality of hollow elements each consisting of two spaced corrugated plates interconnected at their ends, the corrugations of each element being bridged both inside and outside the element thereby providing a plurality of flow paths within and externally of the element for the respective heat exchanging fluids. In the preferred arrangement a plurality of elements are arranged in the form of an annulus, combustion air being passed through the elements and receiving heat from hot gases flowing over the elements. Figs. 1 and 3 show a pair of elements each comprising a corrugated plate 11 and a corrugated plate 12 the ends of which plates converge towards each other as shown. The radially outer mating ends of the element plates 11, 12 engage the flanges 13 of a channel member 14 and the spaces between the flanges 13 and the plates 11, 12 due to the corrugations are sealed as by welding or brazing at 15. At the radially inner ends of the element plates 11, 12 the corrugations intermesh along an edge 16 and are joined by welding or brazing. Fluid passages within each element are formed by plates 19, 20 which bridge the corrugations in the manner shown and are joined by transverse plates 21, 22 so that an air inlet header and an air outlet for the element, interconnected by the passages defined by corrugations and the plates 19, 20 are formed. Adjacent elements are secured together thereby forming passages 29 (see Fig. 3) for the heating gas flowing over the elements. The corruagtions in any one element may be parallel (as shown) or oblique with respect to an adjacent element. The element plates may be formed by bending a single plate. The flow paths externally of the elements may be defined by flat plates engaging the crests of the corrugations on the outer side of each plate.
