Title: Improvements in method and apparatus for continuous casting thin walled metal tubes
Inventor: AITKIN OLIVER BROWN
IPC: B22D11/00
Filed: 1966-04-26
Abstract: 1,126,793. Continuous casting-machines. ANACONDA AMERICAN BRASS CO. 26 April, 1966, No. 18190/66. Heading B3F. In the continuous casting of thin-walled tubes, e.g. not greater than 0À25 inch, a mandrel 49 is cemented into a mould 46 and molten metal in a crucible (10), (Fig. 1, not shown), is first collected in secondary reservoirs 50 and 53 before passing through channels 51, 55 and into a tubular space between the mandrel and the mould in which the tube is formed. One or both of the secondary reservoirs may be used and the channels 51, 55 may be radial or tangential to the tubular space or reservoir. For casting very thin-walled tubes a collection chamber (69), (Fig. 10, not shown), is formed by bevelling inwards the mandrel just below its head (66) and axial channels (71) may extend through the mandrel head (66) connecting the tubular space (68) with the crucible (10). The combination of the collection chamber (69) and axial channels (71) provide means for releasing gas caused during cooling and may be incorporated in mandrels used for thicker walled tubes.

Title: Improvements in or relating to receivers of electrical oscillations
IPC: H04B1/22
Filed: 1920-07-05
Abstract: 146,535. Radio Corporation of America, (Assignees of Weagant, R. A.). April 25, 1914, [Convention date]. Wireless telegraphy; thermionic detectors and relays.-For the reception of continuous waves a sufficiently high electro-motive force is first impressed on a local circuit of a receiving valve to produce a note in a telephone included in this circuit, and then a shunt to the telephone is adjusted to eliminate this note. A receiver arranged according to the invention, described as adaptable for the reception of both damped and undamped waves, comprises a valve two electrodes of which are connected by two circuits, one containing an inductance and capacity in series, and the other containing a battery and an indicating instrument. Oscillations received by the aerial 1, Fig. 1, are impressed upon the control electrode 7 of the valve, included in the anode circuit of which is the telephone 10 and the high resistance 16. The telephone is shunted by a condenser 13, whilst across the resistance 16 is connected the inductance 18 and capacity 17. The filament 11 and anode 8 are further connected as shown by an inductance 21 in series with a condenser 20. To receive damped oscillations, the potential of the battery 19 is adjusted until maximum response is heard in the telephone 10. Resistance 16, inductance 18, condensers 17, 13, 20, and the inductance 21, are then varied separately until the maximum effect of each is obtained, the usual tuning adjustments of the aerial circuit and of the inductance 5 and condenser 6 being made in conjunction. Tuning to group frequency is effected by adjustment of the condenser 17 and inductance 18. When continuous oscillations are to be received, battery 19 is adjusted until a high pitched note is heard in the telephone receiver 10. The capacity of condenser 13 is then reduced until this note almost or completely dies away. The same result may be obtained by adjustment of condenser 20, instead of 13, or by a combined adjustment of both. After eliminating the highpitched note the aerial and grid circuits are tuned to the desired continuous wave. In a modification, the inductance 5 is inductively coupled to the aerial circuit. When using the apparatus to receive continuous waves the inductance 18 may be dispensed with.
