Abstract: Abstract of the Disclosure An oscillator circuit is provided for obtaining a low distortion signal for bias and erase.  The circuit is made up primarily of two sections.  One of the sections is a frequency determining LC tank.  Low distortion oscillation is produced with a low Q tank, and supply current is low relative to the tank current.  The other is an AC coupled negative resistance element having a capacitive voltage divider.  The LC tank is made up of a first inductor, and a second inductor which is the erase winding.  The tank also has a series combination of first and second capacitors.  The negative resistance element is formed by a differential pair of first and second transistors.  This pair of transistors is DC biased to a reference voltage through a first resistor, with a capacitor providing decoupling.  A second resistor provides a load for the reference voltage.  The base of the second transistor is biased by a third resis-tor.  The DC current through the first and second transistors is adjusted by a fourth resistor, while fifth and sixth resistors make the current through the fourth resistor split nearly evenly through the transistors.

Abstract: SIMPLIFIED APPARATUS FOR AND METHOD OF TIGHTENING FASTENERS                       By:  Angelo Tambini &      Paul W. Wallace ABSTRACT OF THE DISCLOSURE         The invention disclosed herein relates to a tighten-ing system for tightening an assembly including a threaded fas-tener including a wrench for applying torque and imparting ro-tation to the fastener.  Associated with the wrench is a con-trol system including measuring means for developing a first signal representative of the angular displacement of the fas-tener.  A second signal representative of a constant incremen-tal time is introduced along with the first signal to gradient calculating means which develops a signal representative of the slope or gradient of an angular speed vs. angular displacement curve which could be plotted for the particular assembly being tightened.  When the gradient signal falls to a predetermined percentage of a maximum previously stored gradient signal, at the yield point of the assembly or some similarly significant point characterized by a significant change in slope on the an-gular speed vs. angular displacement curve, a control signal is generated stopping the tightening of the assembly.

Abstract: ABSTRACT         A child safe closure of the kind which is secured to a container by interengagement of locking-lugs within locking recesses is provided with a sealing member which provides a moisture tight seal with an internal wall of the container.  The sealing member has a sealing bead which is inserted deeply within the container opening to a location adjacent or below the lower ends of integrally formed locking lugs or recesses on the con-tainer to avoid any depressions made in the interior wall of the container during cooling of thicker cross sectional portions of the container wall.  A tapered lead-in surface on the container guides and centers the sealing bead as it travels downwardly toward its sealing position.  Preferably, the sealing member is in the form of a separable, flexible sealing fitment retained within the closure cap and formed with an annular flange connected through an annular transverse V-shaped web to a circular planar crown.  An annular wall depends from the annular flange and has the peripheral sealing bead thereon.  The crown of the fitment is compressed against the top wall of the closure cap to bias the locking lugs into locking relation with the recesses on the container.

Abstract: MULTILAYERED SLANT-ANGLE THIN FILM           ENERGY DETECTOR     ABSTRACT OF THE DISCLOSURE         A detector of thermal energy is composed of an insulating substrate such as glass or sapphire coated with a thin film deposit of a slant-angle deposited metal preferably a transition element such as Ti, V, Cr, Co, Ni, Ta, W, U, Os, Ir, Pt and Mb exhibiting  a transverse thermo-electric effect in response to a thermal energy gradient normal to the plane of the deposit.  A layer of an electrical insulating material which is thermally conductive is deposited upon the thin film deposit, using materials such as SiO2, SiO, perylene, etc.  Another thin film deposit of a slant-angle film is deposited on top of the insulating material.          A stack of alternate slant-angle thermoelectric elements and electrical insulating layers is formed to a depth at which the thermal gradient in the lowest slant-angle deposit is marginally advantageous.  An input light, laser or other heat producing beam is applied to the upper layer of the stack. Alternatively, heat can also be apolied to the lower surface through a transparent substrate producing interfacial heating.  Heat leaks into other film layers producing a substantial thermal gradient and hence, a thermoelectric transverse voltage in each of the metal films.  The layers are interconnected electrically.
