Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for encoding and decoding of standard television signals are provided for enabling reception thereof in an intelligible manner only by authorized subscribers.  The scrambling of the audio signals is effected by conversion of analog audio signals to coded digital audio signals.  A plurality of unique pulse coded control signals consisting of 32-bit binary pulse trains are transmitted separately to identify individual authorized subscribers and to provide information needed to unscramble the scrambled video and audio signals.  When there is a comparision between one of the pulse-coded control signals and a unique address code stored at a particular subscriber's receiver, unscrambling of the video and audio signals occurs in the same sequence as used for scrambling so as to provide restored video and audio signals without degradation in picture and sound qualities.  The present invention provides a receiver means capable of receiving such a television signal.  The receiver means includes:  encryption codes signal detector means; aural detector means; inverse encryption means; and analog conversion means connected to the inverse encryption means to return the audio signal to the original analog format whereby program audio may be processed and presented in a conventional manner.

Abstract: ABSTRACT     A surgical cast cutter or other power tool comprises a main tool section and a complementary hose section releasably secured to the tool section rearwardly thereof.          The sections have respective cooperating rib means formed therein which slidably engage each other (in a direction transverse to the longitudinal axis of the tool section) as the sections are brought together; and the sections are retained by a releasable latching means. A low-voltage electric motor in the tool section drives a transmission which oscillates a cutter mounted forwardly of the tool section.  A debris conduit in the tool section communicates with an opening formed in the hose section when the sections are joined together.  The hose section carries a flexible vacuum hose communicating with the opening therein, thereby facilitating removal of dust particles generated during operation of the cutter to remove a plaster cast.  A low-voltage cable is carried by the vacuum hose and is connected to electrical contacts carried by the hose section.  These contacts engage corresponding electrical contacts carried by the tool section, when the sections are brought together, for energization of the motor through a switch carried by one of the sections.  The sections have respective side housing edges which are inclined with respect to the respective cooperating rib means; these side housing edges are brought into substantial abutting engagement when the sections are fully joined.  The opening in the hose section, as well as the rearward opening of the debris conduit, are also inclined with respect to the respective cooperating rib means to assure good sealing engagement therebetween when the sections are fully joined.

Abstract: SKATING DOLL WITH LEGS HAVING ANGLED PIVOT AXIS        ABSTRACT         A skating doll includes a torso upon which are pivotally mounted a pair of legs.  A leg swings, with respect to the torso, from a rearward, outward position to a forward inward position so that the other leg is urged forwardly by the momentum.  Each leg moves out of synchronism with the other and the head is powered for side to side movement so that the weight is on the forwardly moving leg.  The legs include outwardly turned feet supported atop skates oriented to move in a forward direction in response to the inwardly and forwardly directed force applied to the other leg.  As a result the doll moves forward in a rolling, sliding, side to side, swaying motion which realistically simulates the movement of a roller or ice skater.

Abstract: METHOD AND APPARATUS FOR           SEPARATING PARTICULATE MATERIALS            Abstract Particles having different properties (e.g. part-iculate fly ash and carbon) are separated by driving the particles by means of a vibratory feeder (12) forwards along a horizontal electrode plate (1) above which is mounted a second electrode (2) having at least one plate (4) mounted at an acute angle (?) to the horizontal.         Preferably, two plates (4) each extend sideways from a central block (3) of dielectric material. An alternating electric field is generated between the electrodes (1, 2) by a high voltage AC power source (14).  The potential across each plate (4) varies (in particular, decreases)  in the lateral direction, the variation being continuous or stepwise.  The field lines (16) from each plate (4) CURVES to the side and impart centrifugal forces to part-icles charged by friction or conductive induction; which forces separate lighter, more heavily charged particles from the others.  The separated particles are collected in bins (13) arranged around the lower electrode (1).

Abstract: METHODS FOR THE TREATMENT AND PROPHYLAXIS OF DIAPER RASH AND DIAPER DERMATITIS                 ABSTRACT            Methods for the treatment and prevention of diaper rash and diaper dermatitis caused by the prolonged contact of human skin with body waste are disclosed. The methods of the present invention employ the topical application of a minimum inhibitory concentration of a pharmaceutically-acceptable lipase-inhibiting agent to the area in need of such treatment, or the area where prevention is desired. The lipase-inhibiting agent is preferably a water-soluble metallic salt, such as ZnCl2, and is preferably applied in combination with a barrier-like vehicle. The effective-ness of these methods is surprising in light of the present confu-sion and controversy surrounding the actual causes of diaper rash, and the heretofore unrecognized role of lipase as a factor in the cause of diaper rash and diaper dermatitis.

Abstract: DISSOLUTION OF METALS UTILIZING PYRROLIDONE           ABSTRACT           Improved metal dissolution rates are obtained when using a solution containing sulfuric acid, hydrogen peroxide and a cata-lytic amount of pyrrolidone such as 2-pyrrolidone or N-methyl-2-pyrrolidone.           The present invention relates to the dissolution of metals in an aqueous bath containing sulfuric acid and hydrogen peroxide, and in particular to a novel bath composition capable of effecting the dissolution at high rates.  In one specific aspect the invention is concerned with etching of copper in the production of printed circuit boards.                 BACKGROUND OF THE INVENTION           As is well known in the art, in the manufacture of printed electronic circuits a laminate of copper and etch resistant material, usually plastic, is used.  A common method of obtaining the circuits is to mask the desired pattern on the copper surface of the laminate with a protective resist material, which is imper-vious to the action of an etch solution.  In a subsequent etching step, the unprotected areas of the copper are etched away, while the masked areas remain intact and provide the desired circuiting supported by the plastic.  The resist material can be a plastic material, an ink or a solder.           In the last few years, the industry has more and more turned to hydrogen peroxide-sulfuric acid systems for etching the electronic circuit boards, due to the low cost of the etching solu-tions and to the relative ease with which copper values can be recovered from the spent etch solutions.

Abstract: D.C. BIASSING OF MESFETS OPERATED AT HIGH FREQUENCIES     Abstract of the Disclosure Current in the drain-source path of a microwave high-power GaAs MESFET is controlled by a regulating circuit including an integrating differential amplifier whose output controls the gate of the MESFET.  One input of the differential amplifier is supplied with a fraction of the supply voltage, and the other is supplied with a voltage dependent upon the current to be controlled.  During switch-on and switch-off of the supply voltage, the risk of Gunn effect oscillation of the MESFET is avoided by a switching circuit which controls the differential amplifier to maintain substantially zero drain-source current when the supply voltage is below a predetermined level less than its nominal level.
