Title: Television reception arrrangement
IPC: H04N7/04
Filed: 1933-12-22
Abstract: 435,682. Valve circuits for wireless reception. RADIOAKT.-GES., D. S. LOEWE, 10, Wiesenweg, Steglitz, and SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, both in Berlin. Dec. 22, 1933, No. 36066. Convention date, Dec. 24, 1932. [Classes 39 (i) and 40 (v)] The anode circuits of an intermediate-frequency amplifier, which is designed to amplify the intermediate - frequency and the side bands comprising television signals, include coils 10, 18 with damping 11, 17 which is increased to prevent the coil oscillating at its natural frequencies. The receiver shown is for a short-wave, for example 7 metres, modulated by the picture signals directly and by sound and synchronizing signals through intermediate carriers. The sound carrier is a 1,000 m. wave, the synchronizing carrier a 1,500 m. wave and the intermediate heterodyne frequency a 500 m. wave. The aerial 1 is tuned to the short wave and made incapable of detuning by enclosing it, or by a high circuit capacity and a low aerial coupling capacity. The aerial is coupled loosely to the local oscillator circuit 2, for example through a transformer. The intermediate-frequency amplifiers 8, 33 are semi-aperiodically coupled by the coils 10, 18 shunted by the resistances 11, 17 to pass the necessary band width. The sound 22 and synchronizing circuits 28 are loosely coupled inductively to the anode circuits 20, 27 of the second detector 34. A frequency correcting circuit 54 is connected between the second detector and a low-frequency amplifier 41, 42. Alternatively the intermediate-frequency amplifiers have band-pass coupling which passes a band greater than that desired and the extreme frequencies at least as well as the middle frequencies. In this case the correcting-circuit is unnecessary. The high frequency is withheld from the second intermediate-frequency amplifier 33 by a choke 9 and from the heating and anode-potential sources. The anode potential of the oscillator 7 is smoothed to less than 1 per cent ripple. Volume control is effected after the second rectifier. Similar two-stage valves are used in each part of the receiver. The coupling elements between the two sets of electrodes are in the vacuum, and the anode lead of the first set and the grid lead of the second set are brought out of the envelope for connection to one another in the base or to coupling condensers.

Filed: 1955-12-16
Abstract: In a method of producing a Böhnite (a-Al2O3.H2O) layer on etched Al foil, the etched foil is treated in at least one bath of distilled H2O at a temperature below 75 DEG C. and the layer, of thickness 0.02-0.1 micron, is then formed in at least one further bath of distilled H2O having a temperature exceeding 75 DEG C. and a pH value below 7 and finally dried by heating at slowly increasing temperature until its H2O content has decreased to 20 per cent or less.  The temperature of the second bath may be 85 DEG C. and its pH is preferably between 5 and 6.  The pH is adjusted by adding to the H2O chloride-free acid buffers such as CH3COOH together with CH3COONA. The drying may begin at 80 DEG -120 DEG C. and should not finish at a temperature above 250 DEG C. The foil may subsequently be provided with a dielectric film by anodic oxidation and used as an electrode in an electrolytic capacitor.

Abstract: 782,583. Stapling fibres. FELTON, W. Nov. 25, 1955 [Dec. 17, 1954], No. 36537/54. Class 120(3) Filament-stapling apparatus comprises a rotatable shaft 1 mounting discs 2 which are notched to accommodate pairs of radially disposed blades 3 slits or slots 4 in which receive and hold successive parts of the length of continuous filament 5, means for assisting the entrance of the filaments into the slits, and means for severing each filament at points between those where it engages the slits e.g. between adjacent blades of each pair. In commencing the operation of the apparatus shown, a filament is inserted into each slit of one blade 3 so that when the shaft is rotated the filaments will be wound on the structure and be brought into register with the slits (which may be flared) of successive blades 3. The engagement of the filaments may be ensured by discs 7 arranged to rotate and enter and leave the slits of successive blades as the shaft 1 rotates and thereby press the filaments into position; alternatively an oscillating device may. be used, and, in such device shown in chain-dotted lines, a member 15, which is mounted on a lever 16 pivoted at 17 and rocked by a rod 18 controlled by an eccentric 19, has slots 20, into which the blades 3 can enter, and fingers 21 which press the filaments into the slits 4. The severing. means, of the type described in Specification 771,624 comprise a carrier 8 detachably mounting safety-razor blades 9 having cutting edges 12 and sliding in a guide member 10 itself reciprocating on a guide 11 so that, by means of a crank or cam, elliptical or circular motion may be imparted to the edges 12 to cut filaments held between blades '3 of each pair and then withdraw therefrom. The filaments may be clamped temporarily in the slots as by additional slitted blades slidable in relation to the blades 3. The shaft 1 and/or the blades 3 in the discs 2 may be axially movable. If the cut filaments provide tuft lengths for a mechanism, such as a loom, for producing tufted fabric e.g. a carpet or rug, hooked needles 14 may remove each severed piece from the blades 3 and draw its ends through a "fabric" 13. e.g. knitted or woven tissue or a sheet of rubber or paper.

Title: Improved process for purifying titanium tetrachloride
IPC: C01G23/02
Filed: 1960-10-31
Abstract: In the purification of crude vanadium-containing titanium tetrachloride by treatment with known reducing agents to form insoluble compounds containing the vandium, the sludge remaining after the bulk of the purified TiCl4 has been separated is maintained under conditions such that substantially none of the reduced vanadium compound is oxidized until the TiCl4 content of the sludge has been recovered.  The required conditions may be provided by an atmosphere of inert gas, e.g. argon or helium.  Reducing agents referred to are Cu, TiCl3, H2, H2S, carbonaceous organic compounds, and various mineral, animal and vegetable oils.  The reducing agent is preferably added to liquid crude TiCl4 and the mixture is agitated and heated at a temperature up to the boiling point of TiCl4.  The insoluble vanadium compound formed may be separated, e.g. by filtrated, but preferably by distilling off the treated TiCl4 to leave a sludge containing some residual TiCl4, preferably 5-25% by weight thereof. The sludge is then transferred to a boiler and heated under the conditions referred to above to recover its TiCl4 content, preferably at a temperature in the range 136 DEG  - 200 DEG C.  The TiCl4 recovered from the sludge may be mixed with further crude TiCl4 for purification treatment.  In Example 1, TiCl4 containing 0,7% vanadium as a percentage of titanium, in the form of VOCl3, was treated with 0,18% of H2S for 30 minutes at 120 DEG C.  A sludge containing 20% TiCl4 was obtained after driving off the major portion of TiCl4.  The sludge was then heated to 180 DEG C. until a dry, baked residue was obtained, an atmosphere of helium being maintained throughout the heating.  The purified TiCl4 contained 0,01% vanadium, and the TiCl4 recovered from the sludge contained less than 0,02% vanadium.  In Example 2, 0,1% of fish oil was used as the reducing agent under similar conditions, with comparable results.

Abstract: 635,697. Weft replenishing mechanism; shuttles. POLLARD (1923), Ltd., W., and LORD, A. Dec. 19, 1946, No. 37377. Drawings to Specification. [Class 142 (iii)] - In a loom having a rotary shuttle box, the cells of which are brought into action successively by a weft feeler entering a slot in the working shuttle and penetrating a slot in the pirn when the weft is depleted, the shuttle housed in the last cell of the box has means which locate the pirn with its slot out of line with the slot in the shuttle. The weft feeler thus does not operate, consequently the weft runs off completely, whereupon the weft fork stops the loom.
