Title: Improvements relating to the storing and mixing of materials
IPC: B01F5/24
Filed: 1930-01-23
Abstract: 347,628. Mixing-machines. THORNE, C. B., Hawkesbury, Ontario, Canada. Jan. 23, 1930, No. 2372. [Class 86.] A machine for mixing pulp for paper-making comprises a container divided by partitions into compartments to which the material is fed in turn, the bottom of the container being provided with a scraper which discharges a thin layer of material from all the compartments on to a conveyer by which the material is taken to a distributer which discharges the mixed pulp at a predetermined rate and returns the excess to the container ; electrically-operated devices are provided for effecting the distribution of the material to the compartments. The pulp is fed, by a conveyer 260, Fig. 1, to a shoot 254 mounted on an intermittentlyrotated shaft 261 by means of which the pulp is fed to each compartment until the level of the pulp raises a float 280 carrying a contact, the closing of which rotates the shoot to the next compartment. The pulp is discharged from the compartments by a centrally-pivoted arm 223 fitted with scrapers 235 which direct the pulp to an annular orifice 225 from which it is discharged by a second set of scrapers 237 to a conveyer 232. The arm 223 projects through a gap 222 in the wall of the container and is connected to a motor 238 which runs on a circular rail 242 ; a chain surrounding the container is passed over a wheel 243 driven by the motor. The conveyer 232 discharges on to a second conveyer 233 discharging in turn into the distributer 248 which, as shown in Fig. 4, comprises a cylinder having therein a vaned wheel 255 and provided with two discharge shoots leading respectively from the machine and to the shoot 254. The pulp contained in the compartments of the vaned wheel is discharged through the shoot 252 while the surplus is discharged through the shoot 253 to the shoot 254; a fixed scraper 257 is arranged above the vaned wheel. The shoot is intermittently rotated through a continuously-reciprocated pawl and ratchet, the ratchet having gaps 269, Fig. 7, at intervals round its periphery. While the pawl 265 lies in one of the gaps the ratchet remains stationary. When one of the compartments is filled, a rod 276 is depressed through a solenoid, the rod engaging the end 272 of a tooth 270 pivoted on the ratchet, to raise the tooth into the position shown whereby the next reciprocation of the pawl 265 effects a feeding movement of the ratchet which is continued till the next gap is presented to the pawl.

Specified fluoranthenes are 1 : 2 : 3 : 4 - tetrahydrofluoranthene and its 2 : 2 : 4-trimethyl homologue, and 1 : 2-dihydrofluoranthenes such as the 2 : 2 : 4-trimethyl compound.  The reaction with acrylonitrile may be performed in an inert solvent, e.g. a tertiary alcohol, ether, dioxan or benzene, and the use of a catalyst is preferred.  Specified catalysts include alkali or alkaline earth metals, e.g. sodium or calcium, or a hydroxide, amide hydride, hydrocarbon compound, e.g. potassiumphenyl, or alcoholate of such a metal, or a quaternary ammonium base.  The b -aminoethyl compounds may be prepared from the nitrile via the amide by degradation.  The primary amino group may be alkylated in the usual ways, e.g. with halides and sulphonates; cyclic nitrogen compounds, e.g. compounds having a piperidine ring, may be formed by reaction with a dicarboxylic acid or anhydride to give an imide, which is reduced.  The amines from salts, e.g. hydrochloride and phosphate; quaternary ammonium salts are formed in the usual ways.  In the examples: (1) 1 : 2 : 3 : 4-tetrahydrofluoranthene is reacted with acrylontrile in the presence of trimethylbenzyl ammonium hydroxide to give 1-(b -cyanoethyl)-1 : 2 : 3 : 4-tetrahydrofluoranthene, which is catalytically hydrogenated in the presence of ammonia to give the 1-(g -aminopropyl) compound; this may be either treated with formaldehyde and formic acid to give the 1 - (g  - dimethylaminopropyl) derivative, or treated with benzaldehyde to give the Schiff's base, quaternated with methyl iodide, and then acid hydrolysed to give the 1-(g -monomethylaminopropyl) compound; (2) 1-(g -aminopropyl)-1 : 2 : 3 : 4-tetrahydrofluoranthene, prepared in a similar manner to that in example (1), is treated with glutaric acid to give 1-(g -glutarimidopropyl) - 1 : 2 : 3 : 4 - tetrahydrofluoranthene, which is hydrogenated to 1-(g -N-piperidinopropyl) - 1 : 2 : 3 : 4 - tetrahydrofluoranthene. Specification 630,704 is referred to.  A sample has been furnished under Sect. 2 (5) of 1-(b -dimethylaminoethyl) - 1 : 2 : 3 : 4-tetrahydrofluoranthene, which was prepared by methylation of the primary amine obtained from 1 - (b -cyanoethyl) - 1 : 2 : 3 : 4-tetrahydrofluoranthene by alkaline hydrolysis to the 1-propionic acid, conversion into the carboxylic acid chloride, treatment with sodium azide to give the acid azide, and decomposition of the latter.

Abstract: 823,135. Velocity-modulated tubes. GENERAL ELECTRIC CO. Jan. 25, 1956 [Jan. 25, 1955], No. 2495/56. Class 39(1). A velocity-modulated tube consists of a buncher resonator 21, Fig. 1, a catcher resonator 24 and an intervening slow-wave structure, e.g. helix 33, in which the electron beam flow is influenced by an applied accelerating potential without the presence of a transverse magnetic field, the catcher resonator being energised solely by its electron beam. Resonators 21, 24 may incorporate resonant helices 28, 37 and may be tuned by plungers 29, 38. The helix 33 may be contained in a resonator 23 which is provided with a tuning plunger 34. Helix 33 may be resonant or non-resonant and may be replaced by an interdigital or folded waveguide structure with or without external excitation. In Fig. 7, density modulation of the electron beam is accomplished by both velocity modulation and direct radio frequency excitation of the helix. The helix 94 can be resonant in a mode which interacts with the dominant mode of the resonant cavity 92 or resonant in an independent mode. A drift tube 96, supported by a dielectric member 97, is inserted between the velocity-modulation gap 95 and the helix 94. In another embodiment, Fig. 5, a control grid 60 is inserted in the resonant cavity 66 to density modulate the beam in combination with the velocity modulation produced in the gap 72. A three-gas multicavity klystron arrangement is described in which slow-wave structures are provided between the cavity resonators. Specification 780,473 is referred to.

A semi-conductor device having a connecting rod extending from a semi-conductor element thereof is encapsulated by placing an apertured housing member over the device and resting loosely on a base-plate with the aperture in the member surrounding the connecting rod but sufficiently above the end of the rod to form a temporary socket, placing solder in the socket and heating the assembly in an oxidationinhibiting atmosphere to form a bonding seal between the cap and the rod. In the embodiment described, a silicon diode assembly 10 mounted on a base 11 has a copper anode rod 12 joined to the silicon element through a flexible member 13. An apertured copper member 14 is brazed at 15 to a nickel-iron alloy shroud 17 which is separated from an annular metal member 19 by a glass or ceramic seal 18, so that the parts 14, 17, 18 and 19 form an outer housing 16. The recess formed by the top of the rod and sidewalls of the member 14 is filled with solder pellets and after insertion of spacers 27 the device is placed in a furnace where RF heating through a coil 26 is applied in a hydrogen and nitrogen atmosphere to produce a bond between the rod 12 and the member 14. Finally, the housing is evacuated through apertures formed by removal of spacers 27 and encapsulation is completed by brazing members 11 and 19 together.
