Abstract: ABSTRACT OF THE DISCLOSURE According to the invention, on the basis of a logic signal of frequency F a multiplier processes a signal of frequency 4F sampling a A/N converter, which supplies at its outputs the digital values and a bit representing the sign of sin ? and cos ?. These values, processed by a circuit, are restored by two registers, which supply the absolute values of A sin ? and A cos ?. These values are compared in a comparator and as a function of the ratio ?sin ?? / ?cos ?? an inverting PROM and a multiplier calculate either ?tg ?? or ?cotg  ?¦ . The phase angle ? is extracted by a PROM knowing ?tg ?¦  or¦cotg ?¦ and the sine and cosine signs.

Abstract: METHOD AND APPARATUS FOR ANASTOMOSING SMALL BLOOD VESSELS         ABSTRACT OF THE DISCLOSURE        To effect a simple anastomosis of a pair of severed blood vessel portions in a manner which insures patency of the anastomozed blood vessel, a member, preferably in the form of a ring, has means for tethering the blood vessel portions thereto under radial stress with the intima of the blood vessel portions apposed.  During surgery, the ring is disposed around an end of one of the severed blood vessel portions, and the blood vessel portions are tethered to the ring at at least three spaced apart locations stressing the blood vessel portions radially outward in several directions to evert the intima and hold the intima of the two portions against each other.        To hold blood vessel portions in close proximity during anastomosis, a pneumatic clamping device is provided which grips the blood vessel portions with a precise force according to the fluid pressure supplied thereto.  Precise control of gripping force assures a firm grip that is not excessive and does not damage the blood vessel portions.  Preferably a portion of the clamping device is integrally formed with the ring and is frangible therefrom permitting the clamping device and ring to be prepackaged in a sterile container with the ring prepositioned relative to the clamping device and separated upon completion of the anastomosis.

Abstract: Abstract Of The Disclosure A lockset for use on any one of various door panels of different thickness and hinged on a door frame includes a latchbolt adapted to project into a holder on the door frame and to retract therefrom.  Inner and outer knobs are rotat-ably mounted on opposite sides of the door panel to rotate about a common axis and relative to inner and outer escutcheons held against the panel of whatever thickness.  Inner and outer spindles are engaged by the knobs and turn in the escutcheons.          The spindles rotate a rectangular tube interengaged with the latchbolt for all axial positions of the knobs to provide retraction thereof.  A push button in the inner knob, when latched in a depressed position, secures the outer knob against rotation by a nonrotatable engagement with the inner escutcheon.  Rotation of the inner knob releases the push button from the depressed position and frees the outer knob for rotation.  An aperture in the outer knob allows insertion of an emergency tool to release the push button from the depressed position.

Abstract: Elevator Motoring and Regenerating Dynamic Gain Compensation Abstract A polyphase induction motor propels an elevator car.  The motor is powered by a multiphase inverter which receives power from a battery. The inverter is controlled in such a way as to control the fre-quency and amplitude of the power supplied to the motor in order to control the motor's speed, acceler-ation, and slip.  That inverter control is accomplished by sensing the motor's speed and in response providing predetermined slip and torque signals.  The slip can be controlled over a range which can provide negative slip, by which power is regenerated into the battery, which is thereby charged, and positive slip for motor-ing torque.  A charger also charges the battery.  The motor and its controls are thereby ostensibly isolated from the power system that supplies power to the charger, the battery handling the peak power require ments.  Thus, little noise is injected into the power system.  Speed loop gain is adjusted depending upon whether the motor is motoring or regenerating.  This motor control system is thus efficient to operate, economical to build and very quiet.

Abstract: Abstract of the disclosure:     The crease displacement and the achievable dilu-tion factor in the conventional continuous pretreatment or aftertreatment operations of fabric ropes with liquid means in rope washers are not adequate, and consequently the water consumption necessary for satisfactory results is too high.  To date the existing problems can only be solved with squeeze rollers which, however, have an ad-verse effect on the goods.       According to the invention the textile rope is now introduced into a treatment store of a liquid-opera-ted jet apparatus, is subjected to the action of the treatment liquor, is then carried along by a steam- or more generally gas-operated jet arrangement and conveyed into an interim store, where dewatering takes place.          From the interim store the goods, with satisfactory di-lution factor, are then passed to the next isothermal or non isothermal treatment stage of the same or a very si-milar structure.
