Abstract: 653,691. Cementation. CINCINNATI MILLING MACHINE CO. June 9, 1948, No. 15546. Convention date, June 20, 1947. [Class 72] In a method of case hardening metals the surface to he hardened is smothered in a neutral heating flame and a gas having affinity for at least one of the elements of the surface is supplied and heating is continued to allow the reaction to take place. As shown, applied to the case hardening of a gear wheel, burners 33<SP>1</SP> supplied with oxygen and acetylene in the proportion to produced complete combustion, smother the wheel 13 with a neutral heating flame and, when the temperature has risen to nitriding temperature, a nitriding gas, e.g. ammonia, is supplied to the heating zone from tubes 83, 84, 85 and 86. A thermopile 88 focussed on the wheel stops the heating and causes the ejection of the work into a quenching bath when the desired temperature has been attained. The workpiece is removed from the quenching bath by a conveyer 168. If a carbon case is required the oxy-acetylene flame is adjusted to a carbon-rich condition and, if desired, a nitrogen containing gas may be added to give a combined carbon-nitrogen case. The gas valves, ignition of the gas, extinguishing of the flames and the ejection of the work are under the control of an electrical system, details of which are included.

Title: Improvements relating to track circuit signalling systems for railways and the like
IPC: B61L23/16
Filed: 1942-11-05
Abstract: 561,914. Railway signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and COLEY, J. P. Nov. 5, 1942, No. 15604. [Class 105] In a track-circuit signalling system of the kind in which the rail sections are supplied with code impulses having a frequency determined by traffic conditions in advance, and using master code impulses to feed the track relay at the entrance alternating with feed-back impulses operating an approach-locking or other relay at the exit end, energy is supplied only at the entrance end of the section in parallel with the track relay, the rails at the exit end being connected together alternately through a rectifier and through the winding of the approachlocking or other relay. As shown, energy is supplied from terminals BX, NX of an A.C. source through a transformer T having its secondary winding 5 connected across the rails 1, 2 through a suitable resistance or impedance 6 and in parallel with the track relay CFR which controls signal Sl-at. the section entrance. At the exit end the rails are connected together by contacts 17, 18 of a code-transmitting relay CTP through front contacts 19, 20 and rectifier R1 or through back contacts 23, 24 and a fullwave rectifier R2, the output of which energizes the feed-back relay RCFR. These connections are made alternately with a frequency determined by traffic conditions in advance. As described, a coding device CT operates its contacts 9, 10 with frequencies of 180 and 75 per minute respectively and the frequency supplied to relay CTP depends on the position of contact 16 connected to a source of current, contact 16 being the armature of a relay, not shown, the energized or de-energized condition of which depends on the condition of signal S2 for the section'in advance controlled from the cabin. With the track section unoccupied, the master code impulses supplied each time rectifier R1 is in circuit operate contact 8 of relay CFR with corresponding frequency and cause decoding deviee DA selectively to operate one or other of relays HR, DR controlling signal S1. The intervening back-feed impulses operate contact 29 of relay RCFR, alternately energizing relays FSR, BSR, the circuit of the latter including 'contact 32 of the former. Both these relays are of slow release type and remain picked up so long as back feed code current is supplied. Contacts of relay BSR control approach locking or other circuits. When the track section is occupied relays CFR, RCFR, FSR, BSR are de-energized.
