Title: Improvements in condensation of metallic vapours
IPC: C22B19/18
Filed: 1935-02-11
Abstract: 451,774. Condensing metal vapours. ST. JOSEPH LEAD CO., 250, Park Avenue, New York, U.S.A. Feb. 11, 1935, No. 4364. Convention date, March 8, 1934. [Class 82 (i)] The vapours of volatile metals such as zinc, mercury, cadmium, magnesium, or tin are condensed by being drawn under vacuum through a bath of the liquid or molten metal which is agitated by the passage therethrough of the vapours, which are retarded by a series of baffles on the upper wall of an inclined condensing chamber. In the case, for example, of zinc, a bath of the molten metal in a chamber 1 is supplied with zinc vapour from a duct 2, and is subjected to a vacuum of 6 to 20 inches of mercury by a pump 4, so that the passage of the vapour agitates the molten metal, baffles 5 and 6 being provided to increase the agitation. The uncondensed gases such as CO are drawn off through chamber 3, washed in sprays 9, and collected in a gas holder 11. The temperature of the molten metal is maintained constant by pipes 12 in connection with a cooler 13, circulating pump 16 and furnace 14.

Title: Method of and apparatus for electron multiplication
Inventor: VINCENT CHARLES HOLMES
IPC: H01J43/04
Filed: 1956-02-11
Abstract: 820,736. Discharge apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Feb. 4, 1957 [Feb. 11, 1956], No. 4366/56. Class 39(1). A method of electron multiplication in which an output current, variable at all times with a variable input current, is obtained, comprises causing an electron stream to pass in succession through a series of electrodes in a gas, using the Townsend electron avalanche process in the gas at the stages between the electrodes, and attenuating at the interposed electrodes the effects which may cause feedback between any two stages. In the electron multiplier shown a cathode 10 and an anode or collector plate 14 are located at the ends of an assembly of apertured electrodes 11 mounted on conductive rings 12, e.g. of brass, spaced by insulating rings 13, e.g. of ceramic. A thin window 11A permits high energy particles or incident light to impact the cathode. Alternatively electrons may be emitted from the cathode by a nuclear reaction therein, or may be released by ionization of the gas, or may be introduced into the input region by any other means. The anode 14 has an inlet 15 for the gas filling, which may be air at a pressure of from 1/10 to ¢ mm. of mercury. An outlet may be provided to permit the gas to circulate, or the inlet may be sealed after filling. The rings 12 are adapted for connection to a potential divider. A grid may be placed between the anode 14 and the last electrode 11 and held at a fixed potential, and the time constant of the anode circuit may be made small by connecting a condenser in series with a restrictive load to enable very short pulses to be amplified. The apertures in the electrodes 11 may be formed by punching holes or by a photoengraving process. The holes are staggered in position in successive electrodes and may be confined to a central circular area of the electrodes. An axial magnetic field may be applied. In an alternative arrangement, Fig. 3 (not shown), the apertured electrodes are in the form of wire grids and the electrode assembly is enclosed in a vacuum tight envelope of insulating material, the cathode being connected to a negative voltage and a lead from the grid next adjacent the anode being connected to earth through a resistor. The rings 13 are made of resistive or semi-conductive material to provide uniform potential drops between the grids. The anode is insulated from the adjacent grid and has a lead for the output current.

Abstract: 1299673 I. C. engine valve gear FIAT SpA 29 Jan 1970 [13 Feb 1969] 4369/70 Heading F1B [Also in Division F2] In a valve operating mechanism including a rocker 17 operated from a rotary shaft 12 and having a cam surface 18 formed of a section 20 concentric with the rocker axis and a valve lift section 21, the cam surface acts on a rocking member 23 and the valve lift opening period and timing are conjointly adjustable. In the embodiment shown, the rocker 17 is operated by an eccentric 13 on the shaft 12 through a connecting rod 15 and the shaft 24 of the member 23 is angularly adjustable about the rocker shaft 19 by lubricating oil under pressure supplied to a cylinder 27 in a member 26 supporting the shaft 24. The cylinder 27 contains a piston 28 reacting against a fixed surface 30 in the engine cylinder head 11'. A valve 34 in the oil supply line 32a to the cylinder 27 is controlled by a centrifugal governor 37, which also controls the valve inlet pressure, and a capsule 38 which is subject to the engine intake manifold vacuum. The radius of curvature of the valve stem operating surface 25 of the member 23 may be on the axis of the shaft 19 when the valve is closed or displaced therefrom to provide for variation in clearanel in the mechanism with adjustment of valve lift. In this embodiment separate shafts 12 are provided for the inlet and exhaust valves, Fig.1 (not shown). In a further embodiment, Figs.5 and 6 (not shown), a rotary shaft 12 in the engine cylinder block 1 operates overhead inlet and exhaust valves through respective eccentrics 13, connecting rods 15 and rockers 17. The shafts 24 of the members 23 are mounted in respective arms (47) pivoted at one end on the respective rocker shaft 19 and having at the other ends nose portions (48) which contact respective downwardly sloping top faces (54, 55) on a piston (50) of an hydraulic actuator (51). In another embodiment, Fig.8 (not shown), the eccentrics 13 are coupled to the rockers 17 by respective pairs of connecting rods (15,62). The pairs of rods are connected by respective bellcrank levers (58) mounted on a shaft (59) coupled by an arm (64) to one of the rocker shafts 19. The bell-crank lever shaft (59) is adjustable by a piston hydraulic actuator. In a final embodiment, Fig.9 (not shown), the inclined in-line inlet and exhaust valves are actuated from a respective eccentric 13 connecting rod 15, rocker 17 and a member 23 having one end contacting the valve stem and the other end co-operating with the cam surface 18. 'The rocker shaft 19 is mounted in an arm (69), pivotally mounted on a shaft (70), for angular adjustment by an hydraulic piston actuator. The end of the member 23 co-operating with the cam surface 18 has an arcuate surface (66) with its axis of curvature on the axis of the shaft (70) of the arm (69) mounting the rocker shaft 19 when the valve is closed.

A vehicle with an earthing device 40 controlled by the vacuum in the engine induction manifold is provided with a warning light controlled by an electric switch responsive to the position of the earthing device to show when the accelerator is released. In Fig. 3 the device 40 is actuated by piston 53 in vacuum cylinder 41 connected by pipe 42 to the induction manifold adjacent the edge of throttle butterfly valve 44 so that when the engine is running normally the manifold vacuum holds the piston 53 against end wall 60 and the device raised and the switch open. When the accelerator is released the pressure rises above valve 44 permitting the device 40 to fall thereby closing the switch to illuminate the light, which is preferably at the top or bottom of the vehicle's rear window and in circuit with the ignition switch. In an alternative arrangement (Figs. 1, 2, not shown) the piston may be spring loaded and the cylinder connected to the manifold below the butterfly valve.

Abstract: 285,389. I. G. Farbenindustrie Akt.- Ges. Feb. 14, 1927, [Convention date]. 2-Thionaphthene-3-indole-indigoid dyes are obtained by condensing 6-amino-oxythionaphthene with a 5 : 7-dihalogenisatin and then introducing two chlorine atoms into the 5 : 7-positions on the thionaphthene side by means of sulphuryl chloride, or by condensing 5: 7-dichlor-6-aminooxythionaphthene with a 5 :7-dihalogenisatin. According to examples, (1) , 6-amino-oxythionaphthene is condensed with 5 : 7-dibromisatin in acetic acid containing a little hydrochloric acid, or with 5: 7-dichlorisatin in alcohol in presence of sodium carbonate, and the product chlorinated with sulphuryl chloride in mono- or di-chlorbenzene : (2) 5 : 7-dichlor-6-amino-oxythionaphthene is condensed with 5 : 7-dibromisatin. The products dye cotton from the vat in brown shades of greater purity and fastness to kier-boiling than those given by the brown dyestuffs of Specification 28170/09. 5 : 7-Dichlor-6-amino-oxythionaphthene is obtained by chlorinating 4-nitro-1-aminobenzene, acetylating and reducing the resulting 4-nitro- 2 : 6-dichlor-1-aminobenzene to obtain 4-amino- 2 6-dichlor-1-acetylaminobenzene, and subjecting the latter to the action of sulphur chloride according to Specifications 17417/14 and 18292/14.
