Title: Drilling rig monitoring system
IPC: E21B45/00
Filed: 1980-08-26
Abstract: In a drilling rig, parameters of interest (e.g. rate of penetration and drill bit location, number of stands, monkey board position) are calculated and displayed by a unified electronic system. A weight transducer measures the load of the drill string on the rig. A movement sensor provides information on movement of the hook. An internal clock provides time signals. The relevant parameters are calculated, using a microprocessor, from at least the first two of these three factors.

Title: Yarn defect indicator
IPC: D04B35/10
Filed: 1981-01-07
Abstract: A knitting machine has a yarn defect indicator mounted within the yarn feed system between the yarn supply and the needle-operating yarn feed carriage. A slotted, hinged member 11 hinged at one end 36, 37 to a support member 10 and slotted by one or more slots 46 at its opposite end, has a central projection 14 which is positioned over a bell 13. The yarn in use is caused to run through one or other of the said slots. A knot, slub or other thickening fault in said yarn, restricted by the width of the said slot and being tensioned towards the knitting machine needle bed by the knitting process, lifts the said hinged member 11 to an angle governed by two stop blocks 38, 39 at which point said fault slips clear of the slot, allowing the said hinged member 11 to fall back to its original position and in so doing, the central projection 14 strikes the bell 13. A stop motion switch may also be actuated. <IMAGE>

Patent GB-2075201-A (GB)
Title: Electronic proximity switch
IPC: H03K17/95
Filed: 1981-05-01
Abstract: An electronic proximity switch comprises an oscillator O feeding a demodulator D, which feeds a trigger circuit T which in turn feeds output circuitry R and a hysteresis switch H which completes a feedback loop to the oscillator. A piece of metal moving away from the oscillator 0 causes it to start oscillating, and the oscillation is fed via D, T, and H to increase the loop gain so that the piece of metal must be moved by a significant distance towards the oscillator to damp it sufficiently to stop it oscillating. In addition, there is a feedback from the demodulator D to the oscillator O, which has an inherent high loop gain which is reduced by this feedback when the oscillation amplitude reaches a level somewhat below the switching point of the trigger circuit T. This increases the response speed of the circuit when a piece of metal is removed from the oscillator. <IMAGE>

Title: Analysis apparatus
Inventor: BOWMAN GEORGE EDWARD
IPC: G01N21/55
Filed: 1982-04-07
Abstract: To indicate the amount of a constituent in a substance, for example moisture in hay, a pair of light-emitting diodes 1 and 2 have their emissions reflected from the substance analysed. The diodes emit radiation in narrow bands selected so that there is differential reflection depending on the proportion of the constituent. the supply currents to the diodes are switched in alternate sequence and their relative magnitudes adjusted to give minimum output at the switching frequency. For determining the proportion of moisture in hay suitable wavelengths are 1450 nm and 1300 nm. The diodes may be InGaAsP/InP diodes with the proportions of the constituents adjusted to give emission at the required wavelengths. Detector 14 rectifies the A.C. present due to the inequality of the magnitudes of the radiation reflected at the two wavelengths. Additional diodes and means for switching supply currents to selected pairs may be provided. <IMAGE>

Title: A fighting sport game machine
Inventor: YOSHIDA TAKAO
IPC: A63F9/24
Filed: 1982-09-29
Abstract: An electronic fighting sport game apparatus includes stamina data memory sections which store initial and current stamina data of fighters or boxers. A stamina data arithmetic section reads out the current stamina data of the attacked boxer from the stamina data memory section when one of the boxers delivers a clean punch. The readout stamina data is decreased by a predetermined amount. The decreased stamina data is stored again in the stamina data memory section. The action or movement of the boxers is performed in accordance with stamina data. The winner or loser is judged by determining whether the final stamina data of a boxer is larger or smaller than that of his opponent.
