Title: Improved apparatus for the heat treatment of metal wire, strip and the like
IPC: C21D9/62
Filed: 1942-05-01
Abstract: 560,599. Heat treating wire &c. ARNOLD, C. (Wood, W. H., and Trautman, O. C.). May 1, 1942, No. 5920. [Class 72] Relates to apparatus for heat treatment of metal wire, strip, or the like in which the advancing wire &c. is heated by an electric current, the electric connections with the wire &c. being made by means of molten metal baths. The second metal bath D, Fig. 1, through which the wire 41, Fig. 2A, heated by the electric current passes and in which the quenching operation is commenced, -is provided over part of its surface, through which the wire leaves the molten metal, with a bath of quenching oil 37, which extends beyond the molten metal bath and through which the advancing wire passes in order to effect a second stage in the quenching operation. The advancing wire is maintained below the surface of the molten metal by sinkers 52 which are so insulated that no current passes between the sinker and the wire, so as to avoid surface scratching and pitting. A condenser F, Fig. 1, is connected to the two molten metal baths in parallel with the advancing wire to prevent arcing between the wire and the'surfaces of the baths. The wire has a thin coat of oil applied thereto before entering the first molten metal bath. The second molten metal or quenching bath has a false bottom 9, above and below which the molten metal is circulated. The-false bottom slopes upwardly at the end where the heated wire enters, the speed of the circulating metal at that part, and therefore the speed at which it leaves the heated wire, being thereby increased. The metal leaving the incoming wire passes to the intake 16 of a circulating pump which delivers it through a port 19 from which it passes back under the false bottom to the other end of the bath. Electric heating appliances 25 are arranged immediately under the false bottom of the bath, and an air passage 3 connected with a blower 63<1> is arranged below the bath, one or other of these appliances being put into or out of operation by a thermostat inserted in the molten metal. A transverse dam 48 limits the extent to which the secondary quench oil overlies the surface of the molten metal. If desired, a high flash-point oil may overlie the molten metal on the other side of the dam, i.e. the side' on which the heated metal enters the bath. The apparatus may be employed to secure martensitic hardening in steel wire. The wire is quenched from an austenitic temperature, e.g. above 1580‹ F., to approximately 425‹ F. in a molten metal bath consisting of lead-tin alloy, Wood's metal, or other alloy liquid at 425‹ F., the wire then being subjected to a secondary oil quench from the overlying oil bath.

Filed: 1966-02-10
Abstract: 1,092,585. Radio navigation. DECCA Ltd. Oct. 6, 1966 [Feb. 10, 1966], No. 5933/66. Heading H4D. The invention is concerned with phase comparison hyperbolic navigation systems, e.g. of the " Decca " (Registered Trade Mark) Navigator type and has for an object the overcoming of skyway phase errors over a local area of interest. A monitoring station 20 is positioned at the area of interest, e.g. a helicopter landing stage, and receives the signals from the three phase synchronized transmitters 10, 11, 12. The phase differences between pairs of the signals are determined and translated into corresponding shaft rotations by means 22. The shaft rotations are communicated to respective comparators 29, 30, 31 and the correct phase differences, known from the known positions of the transmitters and monitor are also fed to the comparators 29, 30, 31 in the form of rotations of knobs 26, 27, 28. The outputs of the comparators represent said phase errors and are digitized at 32 before being transmitted to the mobile station 40 by means of a U.H.F. or V.H.F. radio link. At the mobile station, which must be near said area for said errors to be appropriate, the position defining phase differences in the received transmitted signals are converted to respective rotations of shafts 43 which are further converted to digital signals in means 44. The received digital error signals from the monitor are used to correct the position defining signals in means 45, and the corrected signal used to actuate a chart display 47 via a computer 46. Alternately three digital or dial indicators may be used, with the error signals correcting the datum thereof.
