[Class 39 (i)] A discharge device, having a liquid cathode, is provided with a nozzle system, which is arranged between the cathode and the condensation space, and consists of inserts separated from one another and widening in the direction of the condensation space, the anode arms being arranged laterally of the nozzle. The nozzle comprises conical inserts 4 .. 7 to which the vapour is guided by an insulating insert 3. One or more of the inserts may form anodes for maintaining the arc. To maintain constant the pumping action of the nozzle, means may be provided to maintain constant the vapour stream, or variations of the pressure may be checked by metal sheets 10 which are provided with staggered apertures and are arranged apart a distance which is equal to or less than the mean free path; the apertures should be large enough to prevent extinction of the discharge by the space-charge layers on the sheets. A positive potential may be applied to the sheets at the moment of ignition or during the period when current is being transmitted. A potential gradient may be obtained by connecting the sheets together through resistances and the positive potential is connected to the sheet which is most remote from the cathode ; the resistance may consist of a helical or spiral wire arranged within the vessel and arranged around the sheets. Alternatively alternate sheets may be connected to positive and negative potentials to prevent the passage into the anode arm of positive or negative ions. Electrodes 13-16, which are connected to a capacitative potential divider, may be arranged to absorb ions. Ions moving along the axis are collected by ,an anode 17 provided with a pear-shaped cavity so that an internal fieldless space is formed in which any secondary electrons, generated by ion impact, are not accelerated. The anode 17 may be used for starting. To maintain constant the vapour stream, the maintaining arc is regulated in accordance with the load, e.g. the anode 7 is connected through a battery 19 and a resistance in the load circuit to'the cathode, or a supplementary voltage may be supplied inductively to tho circuit of the anode 7. Alternatively, the cathode spot may be thermally insulated by the quartz insert 3. The condensation chamber 8 is cooled by gas circulated through a screen 21, and the anode arm may be heated by radiation. The cathode may consist of an alloy of mercury or of alkali or alkaline earth metal. A separate ignition device may be provided if no gas filling is provided.

Title: Colloidal alumina monohydrate
IPC: A23L29/294
Filed: 1964-06-11
Abstract: Colloidal size particles of a -alumina monohydrate of boeharite structure and which contain only trace amounts of inorganic impurities are obtained by hydrolysis, with water of an aluminium alcoholate followed by contacting the resultant alumina with at least one weight per cent based on the alumina of an acid (e.g. acetic) for 1 minute to 8 hours.  The alumina may be separated from at least a portion of the alcohol resulting from hydrolysis before acid contacting.  The alcoholate may be prepared by oxidation of an aluminium alkyl having a C2 to C10 alkyl group.  The aluminium alcoholate may be hydrolysed in the presence of water and an organic solvent of low solubility in water (e.g. butanol); in this way an aqueous phase containing alumina may be separated from the alcohol hydrolysis product. Heating at 150-300 DEG  for 1 minute to 8 hours may be applied at this stage and mechanical agitation (e.g. stirring or ball-milling) may be applied.  The aluminia obtained by hydrolysis of the alcoholate may be dried to an alumina content of at least 50 weight per cent before acid treatment.  The particles of a -alumina monohydrate may be recovered by spray drying.  The particles may be in fibrous form when stirring is applied at the acidification stage and in the form of platelets when ball-milling is used.

Abstract: 1355871 Regulating fluid-pressure WESTFALIA SEPARATOR A G 19 April 1971 [21 March 1970] 24275/71 Heading G3H A valve-like flow controller which is suitable for use in dairy separators and which acts to maintain a constant pressure, comprises a fixed open-ended cylinder 3 having a plurality of ports 2 in its lateral wall, and a cylindrical sleeve 4 which slides over the cylinder to so vary the degree of opening of the ports 2. The sleeve is formed integrally with, but is spaced from a body 5 which in turn is secured to a compound structure 6 upon which a spring 7 acts. In use, with no flow through the controller the spring 7 so positions the sleeve 4 that the latter practically closes ports 2. Upon a flow being initiated through the controller inlet 13, the degree of opening of the ports 2 is determined by the fluidpressure force which acts within the space 10 on the body 5 and which is opposed by the force of spring 7. The spring tension is adjustable. Should the controller attain a fully open position an alarm signal is triggered by the engagement of structure 6 with an electrical contact 21. In a modification, Fig. 2, (not shown) the spring is replaced by a closed volume of compressed air.

Abstract: 307,274. Jaeger, G. Aug. 28, 1928. Rotary mixers; discharging by tilting.-In a device of the kind described in Specification 262,982 for operating a signal after a predetermined number of rotations the drum of a concrete mixer of the rotary, tilting drum type, means are provided for preventing the tilting of the drum to discharge it till the prescribed rotations have been effected. The apparatus comprises a rod 32, Fig. 1, which is moved longitudinally by the raising of the charging skip and causes a cam 37 thereon to raise a sliding block 28 which carries one end of a worm shaft 24 rotated from the drum. The shaft 24 is thus brought into gear with a worm 19 provided with an adjustable arm 21 which is swung round by the rotation of the worm till it makes electric contact with a pin 23, thus sounding an alarm. The adjustment of the arm 21 on the worm wheel varies the number of rotations of the mixing drum which are effected before the alarm is sounded. The arm 21 also releases a catch 22 holding the block 28 in its upper position; with the release of the catch the block falls and disengages the shaft 24. On the worm shaft 19<a> a member 63, Fig. 3, is mounted fitted with an internal cam in which rides a roller 64 mounted on a pivoted, spring- influenced arm 56. On the worm shaft 24 being thrown out of gear the shaft 19<a> is rotated counter-clockwise by a spring 44 to its initial position. when the roller 64 enters a recess 63<a> and allows the arm 56 to move out of the track of a pin on the sector by which the tilting of the drum is effected, tilting being prevented during the mixing operation by the engagement of the pin with the end of the arm 56.
