摘要： A system for determining cutting-tool wear which utilizes a sensor for producing an output signal representing the cutting profile of the tool and a data processing system using microprocessor control which is responsive to the sensor for storing information concerning such cutting profile when the tool is initially installed and for comparing updated cutting profile information with the stored initial cutting profile information to provide output information concerning the wear characteristics of the tool. The wear information can be displayed, either visually or audibly, or can be supplied to an external data processor, such as the overall machine tool processor, for use therein. The system includes means for correcting errors which arise because of sensor and tool bit characteristics.

Once in position a hood is pivotal to cover the hair and has a nozzle array associated therewith. This nozzle array includes individual nozzles for dispensing a shampoo, creme rinse, or rinse water. The machine can be operated manually to apply shampoo, creme rinse or a water rinse, or can be operated automatically in a pre-programmed manner. The machine is provided with control circuitry including a binary counter and associated decoder logic, temperature regulation circuitry and temperature sensors. The shampoo and creme rinse are contained in individual containers at least one of which is provided with a mixing chamber for mixing the incoming hot and cold water prior to dispensing through the nozzle array.

摘要： A system and method for surveying, with accuracies better than one foot per thousand feet of depth, very deep boreholes having the attendant small diameters, high temperatures and high pressures with very high accuracy. A downhole probe is used having a small diameter, less than about four inches. Three linear type accelerometers and at least two gyros to provide three sensitive axes are fixedly mounted at points spaced along the axis of an elongated, rigid, thermally conductive support member to form an instrument cluster. Signals from these instruments are then processed and transmitted serially over a conductor of a conventional wireline to the surface unit where a surface computer continuously computes and records the current position of the instrument.

摘要： An inertial borehole survey system is disclosed. The survey system of the present invention includes a probe suitable for insertion into a borehole. The probe includes a plurality of temperature sensitive inertial measuring instruments which are utilized to survey the borehole during the descent or ascent of the probe. Accuracy of these instruments is maintained by enclosing the instruments in a thermal insulating package and by providing a mass of isothermal heat absorbing material which exhibits a phase change at a temperature well above most ambient temperatures. In a preferred embodiment of the present invention, a heat absorbing material is utilized which exhibits a phase change at a temperature of 116.degree. F. The probe also includes a longitudinal air passage which permits ambient temperature air to be utilized to cool the isothermal heat absorbing material by passing air through the length of the probe. Currently the instrument cluster is mounted on a member formed of a single billet of metal to form a thermally conductive, small diameter, stiff structure which permits the inertial measurement instruments to be spaced longitudinally in a cluster in order to minimize the diameter to approximately the largest diameter of any single instrument and yet which permits heat generated by the instruments to be absorbed by the heat absorbing material.

摘要： A fault-tolerant clock system for providng digital timing signals (system clock signals) is provided by a plurality of clock sources. Each clock source receives as inputs the generated clock signals from all the other clock sources and contains receiver circuitry to derive a system clock signal from said clock sources which is the consensus clock signals of the other sources. Each clock source generates and distributes to the other clock sources a clock signal which is phase locked to the derived system clock from its clock receiver. In a system of (2r+2) clock sources (r+2) of them will remain phase locked to each other despite up to r clock source failures. Any clock receiver responsive to any (2r+1) of the clock sources can therefore derive a correct system clock despite up to r clock source failures.

摘要： Circuitry for providing electrical isolation between an input signal source and other circuitry which utilizes such input signal. The isolation circuitry uses an optical coupling means comprising a light-emitting diode circuit and a photo-responsive element, the input signal being supplied by a bridge circuit which provides a unidirectional voltage from the input signal which is then applied to a normalizing, or limiting, circuit which converts the unidirectional voltage to a substantially constant value which is supplied to the light-emitting diode circuit. The circuit is responsive to an input signal which can be an AC signal or a DC signal of either polarity, such circuit having a high degree of noise survivability even in the presence of transient noise signals such as "showering arcs" having extremely high amplitudes.
