Abstract: - A B S T R A C T --Apparatus and method for removing material from the surface of fruits and vegetables (produce) and separating the removed material from the resultant mixture utilizes the rotation of an upwardly directed cage formed of elongated rotating spindles having a material removing surface thereon, the cage rotary speed being sufficient, at the interior radius thereof, to maintain the produce in continuous centri-fugal force contact against the spindle material removing surface, but generally insufficient to prevent downward movement or migration of the produce within the cage under the force of gravity.  Produce to be treated is urged into engagement with the spindles and the rotating cage causes the produce to accelerate substantially to said rotary speed, whereby the produce travels with the cage in contact with the rotating material removing spindle surfaces.  The produce moves downwardly through the cage under the force of gravity, but is restrained from moving downwardly as fast as conditions would otherwise dictate by resisting surface contact against the lower portions of the produce, thereby increasing cage residence time.  The resisting surface is displaced downwardly during cage rotation so as to control the descent of the produce downwardly through the cage during treatment.  The removed material is continuously separated from the produce by centrifugal force which may be aided by air suction.

Abstract: ABSTRACT OF THE DISCLOSURE           A process for the preparation of penicillanic acid 1,1-dioxide and esters thereof readily hydrolyzable in vivo.          Said process involves oxidation of a 6,6-dihalo derivative of penicillanic acid, or an ester thereof readily hydrolyzable in vivo, to the corresponding 6,6-dihalo derivative of penicillanic acid 1,1-dioxide of ester thereof, followed by dehalogenation (e.g. by hydrogenolysis).  The 6,6-dihalo derivatives of penicillanic acid 1,1-dioxides, and esters thereof readily hydrolyzable in vivo, are novel intermediates.          Penicillanic acid 1,1-dioxide, and esters thereof readily hydrolyzable in vivo, are known compounds which are useful as beta-lactamase inhibitors and for enhancing the effectiveness of certain beta-lactam antibiotics (e.g. the penicillins) in the treatment of bacterial infections in mammals, particularly humans.

Abstract: CONTROL OF MOTOR DRIVE CIRCUIT BY SIGNALS PROPORTIONAL TO FLUX                   ABSTRACT OF THE DISCLOSURE         An apparatus and method for providing signals indicative of the magnitude and angular position of the DC motor flux of an AC induction motor is disclosed.  The AC induction motor provides controllable rotation and torque in accordance with a drive current of variable magnitude and frequency.  A first signal is provided proportional to the rate of change of the flux of the motor.  A second signal is supplied proportional to the magnitude of the drive current.  A flux signal is generated proportional to the integral of the first signal when the frequency of the output signal is above a preselected value and which is proportional to the second signal when the frequency of the output signal is below the preselected value.  A representative value for the preselected frequency value is 3 Hertz in a 60 Hertz drive system.  The flux signal is effective to control the generation of the drive current.  An embodi-ment of the present invention is shown for the case where the motor is stopped at a predetermined position in accordance with a predetermined conduction state of the inverting supplying the drive current.  Additional embodiments are shown for the general cases where the motor can be stopped at any position and where two flux axes or three flux axes are sensed.  The present invention is particularly applicable for use in an AC induction motor drive system.

Abstract: A B S T R A C T      Hitherto, paper webs for absorbent paper products have been creped either when wet which gives the web bulk but results in a stiff and uncomfortable hand, or when dry, which creates a softer web but one lacking in bulk and absorbency.  The process of the invention includes the steps of creping the web when wet, subsequently drying the web and then re-creping the previously wet creped web, in a dry state.  This produces a web which is both bulky and soft.

Abstract: PARALLEL OPERATION OF TELEPHONE EQUIPMENT ON A DIGITAL LOOP Abstract of the Disclosure Disclosed is a digital station apparatus, such as a digital telephone set, capable of being operated in parallel on a subscriber's digital loop (e.g. in an extension mode) without the need to route all the PCM signals to commom equipment.  Only one of the parallel sets is active at a time, all the others are passive.  In the passive state the telephone set receives only, and does not transmit.  It monitors its own signal magnitude relative to the signal magnitude produced by the active "extension" on the same digital loop.  When its own signal magnitude has satisfied a comparison criterion, then that passive set becomes active and both transmits and receives, while all other sets on the loop are passive.

Abstract: ABSTRACT OF THE DISCLOSURE A process and apparatus are disclosed for continuously manufacturing metallic anodes from molten metal.  The process comprises continuously casting the molten metal in an inclined moulding cavity formed by two movable belts and by two movable side dams so as to produce a metallic strip, and by cutting the hot strip, when it has left the moulding cavity, with at least one plasma torch along a profile such that anodes with a low waste coefficient and without deformation are obtained (figure 1).  This process allows the production of anodes made of very impure copper whereas conventional processes are limited to the production of anodes of relatively pure copper.           This divisional application is particularly directed to a flat anode with a low waste coefficient.  The two faces of the anode have substantially the same smoothness.

Abstract: UK ABSTRACT      A self-loading firearm for firing rubber bullets and the like has an actuating mechanism comprising a toggle linkage which is straightened on operation of the trigger against its spring bias.   Initial straightening of the toggle linkage moves the breech block forward to locate a round of ammunition in a short socket at the chamber end of the barrel.  As the toggle linkage moves over centre it locks the breech block forward and displaces a sear to release the firing pin.  The round is fired with its case virtually unsupported.  On release of the trigger the toggle mechanism is bent so withdrawing the breech block and the spent round which is automatically ejected.  The firing pin is simultane-ously re-cocked.  Rotary and vertical stacking rechargeable magazines are described, from which a fresh round is automatic ally fed to the breech on ejection of a spent round.
