Abstract: -- A B S T R A C T --Disclosed is a tamperproof package comprising a container sealed by means of a turn-off type cap wherein the container has a circumferential sealing finish with a sealing rim at the upper end of the circumferential finish and including cam surfaces with a locking shoulder there-below on the circumferential ceiling finish.  The closure cap includes a top wall with a peripheral skirt depending therefrom and having internal camming surfaces for mating engagement with the cam surfaces on the circumferential finish of the container.  One or more locking lugs or de-tents are flexibly connected to the skirt for flexing in radial planes toward and away from the axis of the con-tainer with the locking lugs or detents and adjacent edges of the skirt having interlocking tongues and sockets to retain the locking lugs or detents engaged with the locking shoulder of the container.  When the cap is turned for re-moval the cam surfaces urge the cap upwardly with the engagement of the locking detents with the shoulder provid-ing a camming action that forces the detents radially out-wardly, breaking or damaging the tongues and visually indicating the breaking of the seal.  The locking detents and all portions of the closure cap remain as a removable unit for reuse or disposal with no separable portions remaining on the container or otherwise requiring disposal.

Abstract: NOVEL ARTHROSCOPE                Abstract of the Disclosure An arthroscope is constructed within a sheath having a cross-sectional configuration generally rectilinear, but with the longer sides slightly arcuate.  The dimension of the sheath along the minor axis of its cross-section is as small as possible to accommodate the systems, e.g., lens, irrigation, instrument channel, included in the instrument.          The radius of curvature of the arcuate sides is selected to approximately match the contours of the joint bones of interest, e.g., the femoral condyles and the tibial plateaus.

Abstract: POWER PANEL SYSTEM WITH SELECTIVE MULTIPLE CIRCUITS      ABSTRACT OF THE DISCLOSURE A panel-type wall system wherein each panel has a pair of electrically connected power blocks disposed adjacent the lower corners thereof.  The opposed power blocks of adjacent panels are electrically joined to-gether by a flexible electrical connector which plugs into adjacent power blocks.  The power blocks and con-nectors define an electrical system which extends longi-tudinally throughout the series of connected panels.  The electrical system is preferably a five-wire system to provide three different available circuits at each power block.  Each power block is provided with several con-nector portions for permitting electrical power to be tapped therefrom.  Different types of power-taps can be plugged into the power blocks.  More specifically, the power-taps include a receptacle unit which can be selec-tively plugged into either or both sides of each power block, and a light-fixture plug which can also be plugged into each power block.  Each of these power-taps has a simple manually actuatable switch associated therewith so the power-tap, when plugged into the power block, can be electrically joined to any selected one of the three circuits.  The power-tap also provides a visual indica-tion as to which circuit has been selected.

Abstract: MOTOR CONTROL CIRCUIT              ABSTRACT OF THE DISCLOSURE         A motor control circuit controls the speed of a single-phase split capacitor or shaded pole electric motor, and permits operation of the motor over a wide range of speeds without stalling.  A first gated bilateral switch such as a triac is connected in series with the motor, and is fired by an integrating circuit through a second bilateral switch such as a diac.          The integrating circuit charges through the start winding of the motor and a potentiometer which adjusts the rate of charging of the integrating circuit for the minimum speed setting desired.  The motor control circuit also includes a temperature sensing bridge which becomes unbalanced as a function of increasing temperature.     A light emitting diode connected to the bridge emits light as a function of the unbalance of the bridge.          A charging circuit is provided which supplies additional charging current to the integrating circuit, and includes photosensors which vary the amount of charging current supplied to the integrating circuit as a function of the light received from the light emitting diode.  As the amount of charging current is varied, the rate of charging of the integrating circuit varies, and the diac and triac are triggered earlier in each half cycle of the AC input voltage.  Earlier triggering of the motor in each half cycle causes the motor to run at a faster speed.
