Filed: 1939-10-02
Abstract: 537,815. Esters ; insecticides. ROHM & HAAS CO. Oct. 2, 1939, No. 27025. Convention date, Nov. 8, 1938. [Class 2 (iii)] [Also in Group VI] Esters of unsubstituted glycols or polyalkylene glycols, in which one hydroxyl group is esterified with a monocarboxylic acid containing at least four carbon atoms and the other is replaced by a thiocyano radicle, are made by heating the monocarboxylic acid ester of a halohydrin with a thiocyanate. The monocarboxylic ester of the halohydrin may be prepared by esterifying the glycol (1 mol.) with the acid (1 mol.) and treating the product with phosphorus trichloride, by reacting a halide of the acid with an alkylene oxide or halohydrin, by reacting the sodium salt of the acid with an alkylene dihalide, or by esterifying the acid with a halohydrin. The replacement of the halogen atom by a thiocyano group may be effected by heating with excess of an anhydrous inorganic thiocyanate in the presence or absence of an anhydrous solvent, e.g. methyl isobutyl ketone, copper or sodium .iodide being used as a catalyst if desired. The monocarboxylic acids may be aliphatic, aromatic, arylaliphatic, cycloaliphatic or heterocyclic, the following being specified : butyric, isobutyric, crotonic, α-ethylbutyric, capric, caprylic, lauric, α-ethyl-hexoic, myristic, naphthenic, benzoic, benzyloxybenzoic, salicylic, clupanodonic, chlorobenzoic. phenylacetic, abietic, campholic, naphthylacetic, tetrahydronaphthylacetic, fluorobenzoic, oleic, linoleic, eloidic, ricinoleic, octyloxyacetic, caprylphenoxyacetic, cyclohexyloxyacetic, m-nitrobenzoic, benzoylbenzoic, acetoacetic, undecylenic, stearic, eleostearic, palmitic, and commercial fatty acid mixtures, e.g. coco-nut oil fatty acids, mixtures obtained by oxidation of petroleum, and tall oils. As glycols, ethylene, propylene and butylene glycols, 1 : 10-decanediol, and diethylene ; triethylene and dibutylene glycols are specified. In examples products are obtained from (1) ethylene chlorhydrin, sodium thiocyanate and (a) furoic acid, (b) benzoic acid, (c) lauric acid, (d) technical coco-nut oil acid, (e) a commercial mixture of fatty acids obtained by oxidation of petroleum, and (f) naphthenic acid, (2) sodium isobutyrate is heated with #: #<SP>1</SP>-dichlorodiethyl ether, and the product heated with sodium thiocyanate, and (3) the sodium salt of coco-nut oil acid is heated with #: #<SP>1</SP>-dichlorodiethyl ether, and the product heated with sodium thiocyanate. The products are useful as insecticides ; they may be dissolved in kerosene to produce insect sprays, or mixed with talc to produce insecti- .cidal dusting powders. They may also be dissolved in a light oil and emulsified in water to produce agricultural sprays. They may be used in admixture with other toxic materials, such as other organic thiocyanates, rotenone, derris extract, pyrethrum, nitro-substituted phenylbenzyl ethers, or nitro-substituted diphenyl ethers.

Filed: 1959-08-10
Abstract: A process for maintaining at a predetermined temperature a reaction zone wherein an olefin is catalytically polymerized exothermally to a solid polymer in the presence of an inert liquid medium, comprises maintaining said medium under such pressure in the reaction zone that the medium will not boil at the predetermined temperature, feeding a portion of said medium and polymer from the reaction zone to a flashing zone of lower pressure whereby some of said medium vaporizes thereby cooling the residue, withdrawing a minor proportion of the residue for the separation of the polymer therefrom, and returning the major portion of said residue to the reaction zone so as to cool the medium therein.  The vapours from the flashing zone may be cooled and the portion condensing returned to the reaction zone.  The non-condensing portion may also be recycled to the reactor, preferably after venting a minor part thereof to the atmosphere. The olefin may be ethylene.

A cluster-type fuel element comprises a plurality of parallel fuel rods each consisting of fuel material enclosed in a can provided with radially directed straight fins extending axially along the full length of the rod, the fins being arranged to form pairs each consisting of two fins, one on each of two adjacent fuel rods and located in the same plane, and removable key members axially slidable in co-operating keyways provided on the radially outer portions of the fins of each of the pairs for connecting the adjacent fuel rods. The key members may take any one of a number of different forms, and may join the fins either externally or internally. One of the former type comprises a thin metallic strip folded in the shape of an " S," flanges which are formed at the extremities of the " S " engaging in longitudina1 grooves along the lateral faces of the fins. At intervals along the fins the directions in which the arms of the 8-shaped strip extend are reversed.

The base member may be T-shaped, as in Fig. 1 and Figs. 2 and 3 (not shown), or may comprise block (1a), Figs. 7, 8 (not shown), soldered to base-plate (1b). Filtering tuning.-A nominal {in the range 100-1000 Hz} operating frequency is defined by choosing a suitable thickness of leaf springs 11, 13, each resonator being tuned to the lowest frequency in the desired pass-band by grinding off leaf spring material adjacent the resonator supports using milling cutter or grinding disc 58 while base member 1 is rigidly supported, each resonator being excited for tuning by its own transducer. The band pass is then determined by controlling the mass, and mass distribution, of the base member, especially and mass distribution, of the base member, those parts most removed from the centre x of oscillation. In the embodiment of Figs. 7, 8 (not shown) thickness (d) of member (1b) defines the band pass, facility being provided for removal, or addition of, removable parts from, or to, the base-plate. The band pass characteristic is displayed in Fig. 5 (not shown), the actual shape being defined by input and output impedances (R), Fig. 4 (not shown), displayed in an equivalent circuit. Filter use.-The filter is used either to extract low frequency signals from high frequency noise, or in a multiplex remote control system in which a mains voltage carrying line also carries control signals. Exemplary materials of construction are given.

Filed: 1957-08-31
Abstract: Apparatus for applying cement to successive workpieces comprises feeding means A which, in a first condition of the apparatus, operate on a rod of thermoplastic cement to urge it into a heating unit B where it is melted, supply means C urging molten cement past open valve means and through an orifice 44 whence it may be applied to a workpiece; in a second condition of the apparatus, the feeding means is unable to urge the rod of cement towards the heating unit, the supply means continues to urge cement towards the orifice, and the valve means is closed, thus preventing molten cement from passing through the orifice. As shown, the rod of cement is urged by toothed feed-wheels 12, 14 towards the heating unit B, the wheel 14 being driven continuously through a slipping clutch, and the wheel 12 being mounted on one arm 18 of a bell-crank lever 20 and <FORM:0896418/III/1> urged towards the wheel 14 by a spring 24.  The cement rod is urged through the guide 10 into the electrically heated unit B, which comprises a disc 4 which is rotated continuously in a cavity providing a tapering passage 26, whence molten cement passes to a gear pump 6 and thence through passages 8 and 40 to the orifice 44 of the electrically heated nozzle unit D.  The orifice 44 may be closed by movement of an arm 54 actuating on a valve rod 48, which is, however, normally held in the open position by a spring 52.  A linkage is provided whereby the feed wheel 12 is disengaged from the rod of cement simultaneously with the closing of the orifice 44, comprising arms 54 and 62, connected by a rod 56, a link 64 connecting the arm 62 to the arm 18 of the bell-crank 20, and an adjustable screw 60 acting on the valve rod 48.
