Title: Tube drawing method and apparatus
IPC: B21C1/06
Filed: 1973-04-24
Abstract: 1395475 Drawing ALUMINIUM CO OF AMERICA 24 April 1973 19366/73 Heading B3P A tube is drawn through a first of at least two drawing dies by a capstan which is driven so that the tube slips on the capstan. A tube 30 is pulled through a cone shaped tower 41 located above a non rotating supply 36 and is drawn through dies 20 or 20A, 21-26 or 21A-26A and 27 by capstans 12-19, all but the last of which are driven so as to cause slip of the tube 30 and are enclosed in an oil bath. Within the tube 30 at each die location is positioned a mandrel (37), (Fig. 2, not shown), all of which, except the one positioned at the last die 27, has an opening (39) to allow passage therethrough of lubricant. The dies may be threaded on to the tube by first inserting lubricant and the first mandrel within the end of a coil of tube supplied by a conveyer (64), (Fig. 4, not shown), and drawing the tube through a die 66 positioned in a holder 51 by a capstan 49. After a sufficient length of tube has been drawn, the die 66 is removed from the holder and the drawn tubing 49A removed from the capstan 49 and hung on a hanger 56 suspended from a rail 60. The latter is then moved to the right along a rail 52 to allow the drawn tubing to be further drawn by a capstan 48 through a second die 72 positioned in the holder 51. The process is repeated until eight coils with intermediate dies have been formed whereupon the rail 60 is moved along the rail 52 to present the coils and dies to the drawing apparatus.

Title: Installations for the separation of dust from a stream of hot gas
IPC: F28C3/06
Filed: 1963-05-17
Abstract: 1,040,604. Preheating cement raw materials. KLOCKNER-HUMBOLDT-DEUTZ A.G. May 17,1963 [May 19, 1962], No. 19690/63. Heading F4B. An installation for the separation of dust from a stream of hot gas comprises a cloth or electrostatic precipitation filter, and a conduit supplying dust carrying gas to the said filter wherein a liquid in finely divided form and a fine granular solid material are introduced into the gas stream upstream of the said filter. In the embodiment shown, hot exhaust gases leave the kiln 1 via the conduit 3 and are utilized to preheat the granular material, e.g. cement, entering the kiln from the conveyer 2. The exhaust gases then pass through a conduit 4 wherein a second granular material is supplied by a screw conveyer 15 and measuring screw 16 from a storage container 14, this material quickly reaching the exhaust gas temperature. Water is injected by an atomizer nozzle 18, and evaporates on contact with the granular material, which material is then removed from the gas stream by the cyclone 5 and returned to the storage container 14. The remaining dust in the exhaust gases is extracted by the tube filter 7, the purified gas being discharged by means of a fan 12. A similar embodiment is described (Fig. 2, not shown), wherein the granular material which undergoes treatment in the kiln is utilized as the material which ensures complete evaporation of the injected water. Using this method, the material removed from the exhaust gases may be returned, not to the container 14, but to the conduit 3 and the kiln 1, either direct (Fig. 3, not shown) or via a series of cyclones (Figs. 4 and 5, not shown).

Abstract: 422,914. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Blyth Road, Hayes, Middlesex, BROWNE, C. O., 29, Monk's Drive, West Acton, London, HARDWICK, J., 66, Drayton Gardens, West Drayton, Middlesex, and BLUMLEIN, A. D., 32, Woodville Road, Ealing, London. July 11, 1933, No. 19691. [Class 40 (iii)] In systems in which the picture signals are mixed with a sub-carrier modulated with e.g. synchronizing impulses, the sub-carrier is prevented from affecting the means for inserting direct current and low-frequency components lost in amplification. The picture signals a, Fig. 3, are interrupted at the end of each line by a signal b of constant amplitude for determining the amount of direct current to be inserted. A synchronizing impulse e, Fig. 5, consisting of a modulated sub-carrier is mixed with the picture signals, giving the resultant oscillatory train of Fig. 6. As applied to a transmitter, the oscillatory train is taken from terminals 5, 8, Fig. 1, and fed to an amplifier 7 whose bias is controlled by the rectifier 10, so compensating for the absence of components incapable of passing the condenser 6. A circuit 9 tuned to the subcarrier frequency prevents rectification of the synchronizing impulses without preventing rectification of the compensating impulses b. As applied to a receiver, a resistance-capacity coupled amplifier 18, 23, Fig. 2, has the bias on the last valve varied to compensate for the absence of components incapable of passing the condensers 16, 22 by the rectifier 37 fed from an amplifier 30, which is fed with the received signals from which the sub-carrier has been removed by the filter circuit 28, 31. This filter is terminated by the grid leak 32 and has a sharper cut-off than the filter of Fig. 1. Specification 422,906 is referred to.

Filed: 1955-07-12
Abstract: 781,816. Radio signalling. MINISTER OF NATIONAL DEFENCE OF CANADA. July 12, 1955, No. 20202/55. Class 40 (5). A V.H.F. control signal is continuously transmitted at a selected power from a first to a second station and only when the detected signal at the latter is at a readable level, transmission of an intelligence-modulated signal between the two stations, on a similar carrier frequency, is automatically effected. The system is designed to take advantage of the reflective properties of ionized meteor trails which are short-lived. In one embodiment station 1 transmits a continuous carrier from transmitter T1 which is detected by the receiver R2 of station 2 and applied to a trigger unit D2 to switch on the transmitter T2 when the receiver output exceeds a predetermined level. Transmitter T2 transmits a carrier of frequency, differing from that of transmitter T1 by up to 5 mc/s., which is received by receiver R1 and applied to the trigger unit D to switch on the modulator M1 so that the transmitter carrier is modulated by the intelligence from source S1. The demodulated intelligence from receiver R2 is stored in a recorder L2 for subsequent playback. The source S1 is also a storage device giving a signal when required. The trigger circuit D2 may also bring into operation the modulator M2 and intelligence source S2 so that the receiver R1 demodulates this intelligence which is fed to a recorder L1. In another embodiment which allows the transmission of intelligence only from station 1 to station 2 elements D2, M2, S2 are omitted at station 2 and transmitter T2 transmits a continuous unmodulated carrier, Fig. 1 (not shown). Split beam antennµ may be used for transmitting and receiving at both stations to increase the number of utilized meteor trails.
