Abstract: Abstract of the Disclosure A drive unit comprised of a pair of axially aligned electrical motors, each motor having a stator, a rotor within the stator and a shaft coupled to the rotor for rotation therewith. The shaft of one motor is tubular to rotatably re-ceive the shaft of the other motor. A ring gear is rigid to the tubular shaft, and a sun gear within the ring gear is rigid to the other shaft.           Planetary gear means couples the ring and the sun gears together, the planetary gear means having arm structure for coupling the same to the shaft of a fluid compressor to be driven, the compressor forming part of a heat pump.           Three speeds are obtainable by operating one or both motors. Relatively high speed is obtained by operating both motors, an intermediate speed is obtained by operating the motor coupled to the ring gear, and a relatively low speed is obtained by operating the motor coupled to the sun gear. Sprags are used on the two shafts to prevent their idling backwards when only one motor is operating.

Abstract: ABSTRACT      A mechanical hand has a rigid enclosure for housing the hand of a user, and at least one pair of gripping elements are provided on the rigid hand enclosure.   One of these gripping elements is pivotally attached to the enclosure so as to be capable of movement towards and away from the other gripping element.   Movement of the movable gripping element, at least towards the other gripping element, is provided by an hydraulic actuator arrangement that includes fluid pressure control means responsive to a manually movable member housed within the rigid hand enclosure.   The arrangement is such that a force applied to the manually movable member by the hand of a user effects rapid movement of the pivotal gripping element until an object is being held between the pair of gripping elements, at which time the force applied to the manually movable member is translated into a force that is applied through the pivotal gripping element to exert a firm grip on the object.     The hand is particular suitable for use with a deep diving suit.

Granted: 1981-08-25
Abstract: ABSTRACT           A drive circuit for a brushless motor which includes rotor position sensors for generating varying signals correspond-ing to the rotary position.    Amplifier stages are coupled to the position sensors, the amplifier stages being responsive to the position signals  produce drive currents which are supplied to the stator windings.  In one embodiment, each amplifier stage includes a voltage amplifier having a linear gain charac-teristic for amplifying the position signal applied thereto, a current amplifier connected in cascade with the voltage amplifier and responsive to the amplified position signal to produce a drive current.  A feedback circuit is interconnected between the output of the current amplifier and the input to the voltage amplifier.  The feedback circuit includes a low pass filter circuit to prevent harmonics of the drive current fre-quency from being transmitted to the stator winding, thereby preventing notching in the drive current.  In another embodiment, the drive circuit also includes a speed sensor, a converter coupled to the speed sensor for converting the frequency of the generated signal to a voltage. A circuit applies the converted voltage to the position sensors so as to modify the position signals in accordance with the sensed motor speed.  A circuit supplies an offset voltage to the last-mentioned circuit such that if the speed of the motor exceeds a predetermined amount, the offset voltage exceeds the converted voltage whereby the result-ant voltage which is applied to the position sensors causes a modification in the drive currents supplied to the stator wind-ings, to produce an opposite torque in the motor.  In this embodi-ment, excess motor speeds are rapidly corrected.

Abstract: Abstract of the Disclosure A method of making a tufted pile fabric includes the step of simultaneously throwing a loop of each of first and second pile yarns which are threaded through a needle having a pair of vertically spaced eyes with the first yarn threaded only through the lower eye and the second yarn threaded through both eyes.  The reciprocatory movement of the needle is controlled such that the upper eye of the needle does not pass through or enter the backing fabric.  The pile yarns extend through the lower eye in the same direction.  In other words, the yarn runs leave the lower eye at the same side of the needle.  The run of pile yarn between the eyes is disposed within a yarn guide groove.  Because the feed of pile yarn to the lower eye is via the upper eye, there is less frictional force between the yarn and the backing fabric.  Also because of the yarn guide groove there is less frictional force between the yarn and the backing fabric.

Abstract: SYNCHRONISER ARRANGEMENTS FOR STEPPED-RATIO TRANSMISSIONS                 Abstract of the Disclosure A synchroniser arrangement for bringing first and second rotary members of a stepped-ratio transmission (for example, a gearbox mainshaft and a constant-mesh gear that is rotatably mounted on the mainshaft) into rotary synchronism.          A primary synchroniser element (for example, a synchro ring) is drivable by the first rotary member and is axially movable into frictional engagement with an intermediate element (for example, a primary synchronising cone) to thereby develop at the inter-mediate element, by the cooperation of respective friction surfaces, a synchronising drag torque component which by the action of a pair of cooperating ramp surfaces-possibly with interposed friction-reducing rollers-produces axial movement of the intermediate element to provide a clamping action at a pair of opposed radially extending annular friction-clutch surfaces of a secondary synchroniser element that is of higher torque-inducing capacity than the primary element, to provide an additional synchronising drag torque component which performs the major contribution in bringing the first and second rotary members of the stepped-ratio transmission into rotary synchronism.

Abstract: DEVICE IN SPRAY BOOTHS FOR E.G. SPRAY-PAINTING.     ABSTRACT OF THE INVENTION      The invention relates to spray booths intended for spraying or painting of articles and designed to be passed by a stream of atmospheric air admitted through inlet ducts and exhausted through outlet ducts and therebetween forced through a water curtain formed inside the spray booth for separating off paint particles remaining in turbulent movement in the air after ejection from a spray gun operat-ing in the interior of said spray booth. To improve economy in the operation of the spray booth it is desirable to bring about heat exchange between the exhaust air and the incoming atmospheric air. However, due to excessive cooling of the exhaust air with its high moisture content and low temperature after passage through the water curtain by the heat exchange with the admitted atmospheric air of low temperature especially during the cooled season there is a great risk of ice precipitation in, and clogging of, the air passegeways in the exchanger. This risk is eliminated according to the invention, by coordination of the operation of the spray gun with periodical interruption of the action of the water curtain.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for discriminating the thermal effect of phase transformation of metals and alloys in the process of their cooling, by measuring the temperature of a metal or alloy being cooled, the time elapsed from the beginning of the temperature measuring cycle and the duration of a temperature arrest occuring in the process of the metal or alloy cooling.          The measured duration of the temperature arrest is compared with a threshold of the temperature arrest duration for making a decision ascertaining the occurrence of the thermal effect of phase transformation if the measured duration of the tem-perature arrest exceeds the threshold of duration of the tem-perature arrest.  The method further includes measuring an increment of temperature of a metal or alloy being cooled re-lative to the maximum temperature recorded during the tempera-ture measuring cycle, calculating a threshold of duration of the temperature arrest as a function of temperature of the metal or alloy being cooled, and measuring increments of these tem-peratures relative to the maximum temperature recorded during the temperature measuring cycle.  The time elapsed from the beginning of the temperature measuring cycle is metered with the threshold value of the temperature arrest duration cal-culated for the moment of occurrence of temperature arrest, being used for the comparison.
