    Abstract: The system allows one to answer his telephone and talk to the caller by means of a remote transceiver which is carried by the person when he is away from his telephone. A base station unit develops and transmits to the transceiver a ringing signal to alert the person that his telephone is ringing. The transceiver is operated to transmit an answering signal which has both a frequency-coded component and a speech-modulated component to answer the telephone. Amplitude comparison and timing circuits are used, together with a frequency analyzer to prevent unwanted answering of the telephone. Means are provided for terminating the call in response to either hanging up the calling telephone, receipt of a dial tone, or receipt of a warning signal on the telephone after hang-up. Also, means are provided for automatic hang-up after a period of time in which no coded signal from the remote transceiver or voice signals from the caller are received. Remote dialing means are provided in which the answering circuitry is used in the initiation of calls from the remote transceiver, as well as in the answering of incoming calls.

    Abstract: A method is disclosed for quench-depositing by plasma spraying onto the substrate an adherent thin coating of a titanium carbide tool steel containing by weight about 10% to 80% of primary grains of TiC and the balance essentially about 90% to 20% of a steel matrix, such that the resulting coating is one characterized metallographically by the presence of martensite. The metal substrate may be aluminum. Preferably, the titanium carbide grains should be rounded to assure a low friction surface.

    Abstract: Greatly increased thermal fatigue cracking resistance of high temperature resistant base metals such as cobalt and nickel and their alloys used to fabricate jet engine components and like parts is realized by diffusion coating the base metal with chromium, silicon and aluminum in particular proportions to diffuse into the base metal to a uniform depth and distribution between and across intergranular boundaries in the base metal, enabling slowed initiation of thermal fatigue cracking in the diffusion coating as well as reduced corrosion in the base metal.

    CPC classification number: G01B5/205

    Abstract: The invention contemplates a gage for vane-class measurement, in which the vane is oriented in space, and in which class is determined by a single angular measurement. The angular measurement is taken about a longitudinal axis which may be considered to be substantially the trailing-edge gage line, and said measurement is made between (a) a radial strobe through substantially the mid-point of the airfoil gage line (along the convex surface of the blade of the vane) and (b) a radial strobe parallel to the orientation of one of the abutment edges of a buttress forming part of the vane. Various structural features enable simple and rapid one-handed manipulation of each successive vane into gaging position, so that the angular (classindicating) measurement is fully repeatable for a given vane, and so that small and minor local anomalies in surface fidelity are substantially eliminated, i.e., they are not effective in degrading the reliability of the measurement.
