Abstract: 416,836. Boning fishes. HENNING, W., 6, Goethe Strasse, Wesermunde, Germany. May 8, 1934, No. 13880. [Class 28 (ii).] Fishes are boned by passing a tool into the body of the fish along and around the backbone, breaking the bone at the tail root, and withdrawing the tool with the bony skeleton. The operation is preferably performed on whole fishes, i.e., not decapitated, in which case it is necessary to sever the backbone where the tool engages it, and if necessary, the gullet may be widened by cutting. The tool consists of a forcep-like device and may be adapted for machine use. The members 2, 4 and 21, 41 are pivoted together at 1 and the parts 4, 4<1> carry forwardly extending substantially parallel prongs 6, 6<1>, 6<2> and 7, 7<1>, 72 which surround the backbone a, the side bones passing between the prongs. The inside edges of the prongs are serrated at 8, Fig. 3, and, when the tail root has been broken, the handles 2, 2<1> are grasped against the action of the spring 3 and the backbone is firmly gripped for the withdrawing motion. The extent of separation of the sets of prongs is determined by a screw 5.

Title: Improvements relating to the desulphurisation and hydrogenation of aromatic hydrocarbons
Inventor: WINSOR JOHN
IPC: C10G45/06
Filed: 1965-10-04
Abstract: 1,141,809. Desulphurization and hydrogenation of aromatic compounds. BRITISH PETROLEUM CO. Ltd. 29 Sept., 1966 [4 Oct., 1965], No. 41940/65. Heading C5E. Aromatic hydrocarbon feedstocks containing 1-50 p.p.m. wt. sulphur are desulphurized without appreciable hydrogenation by passing the feedstock in the liquid or vapour phase over supported nickel at an elevated temperature and pressure in the presence of hydrogen such that the sulphur combines with the nickel but no substantial amount of H 2 S is formed, the equilibrium H 2  partial pressure being greater than the minimum necessary to prevent catalyst deactivation but less than that at which 10 mole per cent hydrogenation of the aromatic hydrocarbons occurs. The preferred feedstock is benzene containing not more than 10 p.p.m. wt. S. The nickel may be supported on the refractory oxides of Group II to V elements or on kieselguhr, pumice or, preferably, sepiolite. The desulphurized feedstock may then be hydrogenated in two stages, both using supported Ni catalysts in which not less than 90% wt. and not more than 99% wt. of the feedstock is hydrogenated in the first stage, the hydrogenation being completed in the second stage; the first stage is cooled by liquid recycle (e.g. cyclohexane) and the second stage is uncooled. Each stage may be carried out in mixed phase and the reactor outlet temperature of the second stage should be less than that of the first stage. The hydrogen used in the process of the invention may be commercially pure or may be mixed gas such as steam reformer tail gas or catalytic reformer off gas preferably containing at least 50 mole per cent H 2 . A H 2  partial pressure of 0.5 p.s.i. and 400 F. limits hydrogenation of the aromatic hydrocarbon during the desulphurization to 5 mole per cent.

Radio-frequency heating apparatus includes an oscillator employing a cavity resonator 2 the walls of which include end plates 6, 15, a triode oscillator valve 1 having a glass envelope, a high internal anode-grid capacitance and an anode cap 7a, the valve being mounted so that the distance between plate 6 and the grid and cathode terminals is less than that between the anode cap and either of plates 6, 15 and the anode cap is connected to plate 15 via an inductor 14 of inductance higher than that of a coupling between the grid or cathode terminal and plate 6 and the inductor inductance is at least one third of the total inductance in the circuit extending between the anode cap and the grid or cathode terminal by way of inductor 14, plate 15, the side walls of the cavity resonator and plate 6, the anode also being connected directly 17, 18 through an aperture in the cavity to a heating electrode 21 or to a plate capacitatively coupled with a heating electrode. A V.H.F. dielectric heating oven which is not critically tuned or sensitive to tuning can thus be fed with high efficiency. In one embodiment the grid pin is connected to a plate 4 which with dielectric layer 5 and plate 6 constitutes a capacitance. Feedback is produced by capacitance between anode 7 and plates 8, 9 which are connected to the filament pins of the valve. The filament supply is introduced by screened H.F. chokes (10, 11, Fig. 3) and filters (26, 27); the grid pin is connected through a screened choke (50) and a grid leak resistor (51) to one of the filament supply connections. The positive H.T. connection is made to the earthed shell of the cavity and the negative H.T. connection is taken to the filament supply line. The valve is forced air cooled. Inductor 14 is preferably cylindrical and coaxial with a cylindrical cavity resonator, but the latter may be square. The inductor may incorporate a longitudinal gap in its circumference to enable its diameter, and hence inductance, to be varied. The cavity is made in two parts which seat on one another through their flanges 39, 40 which are enclosed by a clamping ring 40a. The anode is connected to a spring pad 12 which presses against the base 13 of inductor 14. The output to electrode 21 is taken via spring fingers 38. The oscillator may have two valves in parallel (Fig. 5). In another embodiment a single output line extends from the anode cap to a plate (60, Fig. 6) which forms one side of a variable air spaced capacitor the other plate of which is a heating electrode (61); feedback is by a tuned grid circuit.
