Title: Improvements in or relating to the heat treatment of metals and metallic articles
IPC: C21D1/46
Filed: 1924-04-22
Abstract: 237,337. Imray, O. Y., (Bellis Heat Treating Co.). April 22, 1924. Drawings to Specification. Annealing.-In the heat treatment of metals and metallic articles, the articles are immersed in a bath composed of a fused mixture of salts, the mixture of the salts having a composition so selected that it is the eutectic mixture of the salts. The mixture is also so selected that it has a relatively high temperature of volatilization or decomposition. The articles &c. after heating to the required temperature are removed from the bath and quenched in a bath of oil, brine, or other suitable liquid. In one example the bath consists of a fused mixture of 39 per cent of sodium chloride and 61 per cent of sodium carbonate, and in the treatment of steel having a carbon content of 0.4 per cent the bath is heated to approximately 1500‹ F., the volatilization temperature of this bath being considerably over 1600‹ F. Another example of a bath consists of a fused mixture of 71 per cent of calcium chloride and 29 per cent of sodium chloride.
Patent GB-753753-A (GB)
Title: Selective switching device
IPC: H02J13/00
Filed: 1954-04-06
Abstract: 753,753. Actuation of switches. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 6, 1954 [April 9, 1953], No. 10027/54. Class 38(5) A selective switching device is responsive only to a signal of minimum duration followed at a predetermined interval by a second signal. The initial impulse energizes an electromagnet 26 which attracts a pivoted armature 25 which bears against and actuates a lever 18 and a bellcrank 16 both movable about a fixed stud 12. The lever 18 closes contacts 27 energizing a motor 15 and also brings a pinion 19 into engagement with a pinion 28 driven by the motor so that the pinion 19 rotates and drives counter-clockwise a gear wheel 21a on a cam member 21. If the impulse is of sufficient duration, say at least 3.4 secs., the lower end of a lever 23 which has been lying in a cavity on the periphery of the member 21, is cammed out of the cavity and the upper end presses against a flange 18a of the lever 18 to retain this in position. For shorter impulses, the parts return to their original position. The movement of the bell crank 16 by, the armature takes place against a return spring 17 and actuates a link 29 connected by a spring 31 to a lever 20 pivoted at 14. The lever 20 is thus actuated by the first impulse but its end 20a is brought up against the rim of a cup-shaped member 10 adjustably mounted on the member 21 by means of the holes 10b, and nothing further happens. The members 21 and 10 continue to rotate, making one revolution in a minute, and if a suitably-timed second impulse is delivered during this period to the electromagnet 26, a notch 10a in the rim of the cup 10 will be opposite the end 20a when the latter is actuated so that the end or flange 20a passes through the notch and now rides inside the cup 10. Still later on the cam portion 30b of a member 30 fixed to the member 21 comes between the flange 20a and the rim of the cup 10 so that the lever 20 moves 'still further in a clockwise direction and an arm 20b actuates contacts in a switch 40. The invention may be used for selectively sounding bells in individual classrooms of a school by means of H.F. signals superimposed on L.F. power lines which also supply the power to operate the various synchronous clocks throughout the school and the H.F. signals for regulating the clocks. In this case, a number of switching devices according to the invention are installed in the various classrooms and adjusted to respond to different intervals between signals. Specifications 674,721 and 694,110 [both in Group XVIII] are referred to.

Abstract: 1455507 Anchor bolts OLIN CORP 8 March 1974 [9 March 1973] 10565/74 Heading F2H To enable identification of the length of an anchor bolt, having an expander head 18 and an expansible sleeve 14, after it has been installed in a bore, the outer end 30 of the bolt has an axially extending recess 32 indicative of the bolt length. Preferably, in a set of such bolts, each bolt being of a different length, the diameter of the recess is in inverse relationship to the bolt length, so that the longest bolt has the smallest diameter recess. This minimizes the risk of the indication being falsified. In addition the recesses may have plastics inserts, either forced in or cast in, of different colours to aid recognition of the bolt lengths. Such inserts could be used with recesses all of the same diameter, as the sole identification. The depth of the recess is such that with the anchor bolt installed and a nut 22 tightened thereon, the inner end of the recess is slightly below the outer surface of the nut (Fig. 4, not shown). With longer bolts, one or more distance tubes (24-28) (Figs. 2, 3, not shown) are provided between the nut 22 and the expansible sleeve 14.
