Title: Improvements in lock-nuts
IPC: F16B39/284
Filed: 1925-01-23
Abstract: 235,104. Thompson, H. Jan. 23, 1925. Locking nuts.-A self-locking nut is formed by making a radial and a transverse cut C in an integral threaded collar A, pressing the part D so formed towards the axis of the nut and subsequently heating and tempering. The transverse cut in the collar A is made parallel to the threads of the bolt and the inner edge of the resilient member D is rounded at B. The nut is used in the ordinary way and is locked by the transverse pressure of the member D on the bolt. Specifications 1942/85, 19069/10, 28264/12, and 154,409 are referred to.

Title: Improvements in brush-making machines
IPC: A46D1/10
Filed: 1922-01-24
Abstract: 195,481. Silander, A. E. Jan. 24, 1922. Brush-making machines.- In a brush - making machine comprising a vibratory hopper 1, Fig. 1, fitted with sieves 2 and with vertical partitions forming channels 4 to receive and deliver bristles to slots in a template 5 supported on a reciprocating table 9, a plate 10 is arranged to pack the bristles into the template as it is moved away from the hopper, and a comb 11 sweeps off superfluous bristles on the return movement of the template. The hopper may be provided with two vanes 6 adapted to oscillate as the hopper is vibrated and thereby set up air currents which' facilitate delivery of the bristles. Air under pressure may also be introduced through the top of the hopper. In the construction shown in Fig. 3. the sieves comprise a series of straight rows of parallel wires 13, beneath which is a series of roof-shaped rows adapted to guide transversely-disposed bristles to openings 16 in the sides of the hopper from whence they are discharged into a tray 17. The vertical partitions forming the channels 4 leading to the template 5 are also arranged to form roof-shaped bristle-guides. To facilitate feeding the bristles into the. template 5, the latter may be shaken by means of an oscillating hammer 18 or by knocking the carriage 9 against a buffer 19.

Title: Improvements in or relating to Carburettors for Explosion Engines.
Inventor: FEROLDI ENRICO
IPC: F02D9/00
Filed: 1918-02-06
Abstract: 118,590. Feroldi, E. Aug. 21, 1917, [Convention date]. Spray carburettors.-Additional air is admitted after the throttle has been fully opened either by a spring-loaded valve actuated directly by the throttle when of the butterfly type or, in the case of a rotary-plug type of throttle, by elongating the inlet and outlet orifices thereof so as to register with additional air passages. The air valve 3, Fig. 1, is loaded by a spring 8, and enclosed in a casing 6 with inlet apertures 7, and has a spindle 4 which is actuated by a wing of the throttle 10 after it has passed its open position. In a modification, the valve, in the form of a rotatable disk, is mounted on the throttle-valve spindle and carries rollers which engage with cams on the wall of the induction pipe to throw the valve off its seat. With a rotary-plug type of valve 15, as shown in Fig. 4, the inlet and outlet orifices are elongated to register with air inlets 14 after the valve is fully open. In a modification, only the outlet orifice is elongated, the inlet orifice then serving to throttle the mixture passage 1. Where a secondary carburetting-chamber is employed, communication may be established between the outside and such chamber so as to obviate the effect of the depression of the engine therein.

As shown girders 1, 2 run the length of the installation, the former being positioned to support the cellar arch 7 and the latter being mounted in the back wall 5 of the ashpit space. At intervals the girders 1, 2 are connected by transverse members 6, which support the grate frames 13 and foundation rings 17 for the lining and walls of the crucible holes, and also serve to transmit the thrust of the arch 7 to the back wall 5.
Patent GB-196678-A (GB)
Title: Improvements in vacuum tubes
IPC: H01J25/52
Filed: 1922-01-25
Abstract: 196,678. Robinson, E. Y. Jan. 25, 1962. Thermionic oscillation generators, amplifiers, and detectors.-The space current of a thermionic valve is controlled by a magnetic field produced by a coil disposed within its anode or an extension thereof. In the arrangement shown in Fig. 1 for producing oscillations in a circuit 14, a tungsten control coil 3, setting up the magnetic field, is located inside a filament-cathode 1 and an anode 2. The field is confined to the inter-electrode space by reflection from the anode and from metal shields 6, 7. A polarizing field may be produced by a winding 12 energized by a battery 13. To ensure that the current in the control coil is in phase with the current in the output circuit, the coil may be connected in the output circuit or, preferably in series with the secondary winding 16 of a transformer, the primary 15 of which is connected in circuit with the anode, an oscillatory circuit 14 and a battery 17 or other source. The control coil should have a large resistance as compared with its inductance, or the inductance may be compensated by a capacity 18, in which case the coupling between the windings 15, 16 should be tight. Alternatively the coil may be energized independently by an oscillation generator. In the arrangement shown in Fig. 3<A>, a helical cathode 35 acts as the control coil and is energized by high frequency current produced by a triode 34, the controlling current serving also for heating the cathode, which is connected in series with an inductance 36 and a condenser 37. The anode 38 is connected through a winding 39 of an aerial' transformer and a source of power 41 with the cathode. An auxiliary winding 42 is energized by a battery 43. The control current may be produced by back coupling as described with reference to Fig. 1. At starting the cathode may be heated temporarily from an independent source. Specifications 167,561, 189,125 and 189,135 are referred to.

Abstract: Silica-metal oxide or silica-metal oxide-magnesia cracking or dehydrogenation catalysts are prepared by impregnating an acidic silica hydrosol with a salt of a metal, excluding aluminium, capable of forming the hydrous oxide upon addition of magnesia, adding a water slurry of magnesia, either sufficient to neutralize the free acid when a silica hydrogel-metal oxide catalyst, e.g. containing 10-15 per cent metal oxide, is produced, or excess when a silica hydrogel-metal oxide-magnesia catalyst, e.g. containing 25-38 per cent magnesia and 0.5-5 per cent metal oxide is produced, and recovering the catalyst.  Suitable metal salts are sulphates, chlorides, or nitrates of manganese, zirconium, beryllium, zinc, titanium, cadmium, chromium, copper, and iron.  As described sulphuric acid and sodium silicate are mixed with metal salt and the mixture sprayed, together with magnesia slurry, e.g. 2 parts water to 1 part calcined magnesia, into a liquid, e.g. oil, bath.  The microspherical gel particles, fall through the oil to a water bath, pass to a washer wherein they are water-washed at 125-200 DEG  F., thence to a drier at 200-230 DEG  F., and finally to an activator, wherein they may be activated at 1100-1400 DEG  F.; the gel particles may be dried and activated in combination at 1100-1400 DEG  F.
