Abstract: ABSTRACT OF THE DISCLOSURE            Casting side dam apparatus for use in a twin-belt continuous casting machine of the type wherein two spaced-apart side dams each revolve in a loop traveling  along a casting zone from the input end to the output end of the casting zone and between a pair of revolving spaced-apart casting belts.  The side dams return from the output end to the input end of the casting zone along a return path located away from the casting zone.  The side dams each comprise a multiplicity of slotted dam blocks strung on a flexible metal band.  The dam blocks are each formed of a beryllium-copper alloy also comprising cobalt, the beryllium being present in the alloy in excess of a trace but not more than 0.7% of the alloy, and the cobalt in amount greater than the beryllium but not more than 2.7% of the alloy.  The total of beryllium plus cobalt plus copper is 99.5% minimum.  The alloy is characterized in the solution heat treated and precipitated condition by hardness in excess of the recom-mended minimum of 90 Rockwell B and conductivity in excess of the recommended minimum of 35% IACS.  The dam blocks are resistant to intergranular cracking and chipping over a prolonged discontinuous, cumulative period of exposure, equiv-alent to in excess of 20,000 tons of copper cast, to thermal cycling between temperatures ranging between about 800°F. and about 300°F.  The dam blocks also are characterized by re-taining their hardness in excess of 90 Rockwell B and conductivity in excess of 35% IACS over a prolonged period of such thermal cycling between the upper and lower tempera-tures set forth immediately above.

Abstract: Abstract of the Disclosure A double heterostructure laser having a pair of opposite-conductivity-type, wide bandgap cladding layers separated by a narrower bandgap active region is characterized in that the active region includes a low-loss wavesuide layer and contiguous therewith a narrower bandgap active layer in the form of a narrow strip which extends along the longitudinal (resonator) axis of the laser. Suitable lateral current confinement means, such as reversed biased p-n junctions, are provided to constrain pumping current to flow in a narrow channel through the active layer.  Lasers of this type exhibit relatively high pulsed power outputs (e.g., 400 mW), linear L-I characteristics, stable fundamental transverse mode and single longitudinal mode oscillation.  In another embodiment the surfaces of the waveguide layer adjacent the active layer are provided with distributed feedback gratings.  Also described are techniques for shaping the active layer without the introduction of debilitating defects therein, as well as procedures for LPE growth on Al-containing Group III-V compound layers which are exposed to processing in the ambient.

Abstract: Abstract This invention relates to a thermal window construction which comprises a fixed frame member and a movable frame or operating sash member.  The window is characterized in that the operating sash member includes an outwardly facing glazing surface to which a pane sub-assembly comprising two or more glass lites are connected, the bond between the pane sub-assembly and operating sash being provided by a bead or quantity of silicone interposed between an inwardly directed surface of the sub-assembly and the glazing surface through a laterally open channel, whereby complete filling of the said space may be assured.  The overlapping areas of glass and metal bonded by the silicone rubber material are coordinated with the glass expanse and weight in such manner that the stress applied to the bonded areas will not exceed about 20 p.s.i.  The fixed frame member includes a flange member which outwardly laps the outermost face of the sub-assembly, a deformable gasket or the like being disposed between these parts, to define a weather-tight seal with said outer face.  The assembly includes, in addition, a resilient seal member extending between a thermally isolated portion of the outer frame assembly and engaging and outwardly lapping portions of the movable frame or sash assembly and also an insulating barrier member carried by the movable frame whereby, in the closed position, all portions of the movable frame are isolated from the exterior.

Abstract: ABSTRACT OF THE DISCLOSURE            The specification describes a releasable clip which comprises a band for encircling an article such as a hosepipe to be secured. The band carries at its respective ends complementary interlockable coupling elements for connecting the ends of the band and drawing them together to contract the clip around the encircled article. The coupling element on one end of the band consists of a tongue provided on its upper and lower surfaces with barbed serrations and on the other end of the band the coupling element is a pair of jaws having inwardly facing barbed serrations; each jaw extends in a generally longitudinal direction from the point where it is joined to the band to a tip thereof and a jaw mouth is provided between the tips of the jaws through which the tongue is insertable in the said longitudinal direction tip first into the jaws. The serr-ations on the tongue, when the tongue is present between the jaws, interlock  with the serrations of the jaws and thereby hold  the tongue to prevent withdrawal movement thereof in the said longitudinal direction. The serrations on the tongue and jaws however, allow the tongue and jaws to move relative to each other laterally, to disengage the tongue from the jaws and so release the clip. The releasable clip is moulded in one piece of a plastics material.

Abstract: A CAPACITIVE DAC TO FILTER INTERFACE CIRCUIT    ABSTRACT      An operational amplifier capable of selectively per-forming a variety of circuit functions is provided. A single operational amplifier utilizes switched capacitors for sampling and holding an input signal, for establishing a low frequency pole, for applying the sample to an output capacitance to charge the capacitance and for comparing the input signal with a reference. The multi-function cir-cuit provides a large savings in circuit area and permits versatility of circuit applications. One embodiment of the invention is to utilize a companding DAC having a capaci-tor array which may be used as the output capacitance of the operational amplifier circuit. The DAC provided utilizes an R ladder DAC coupled directly to a C DAC and has a switching structure that is simpler than comparable prior art circuits. The DAC is asynchronous and has pro-grammable A- and Mu-225 law PCM conversion capability.          Coupled directly to the C DAC is an operational amplifier receive filter circuit which utilizes the C DAC as an input capacitor thereby eliminating the need for a buffer amplifier and allowing the DAC to be used for both analog to digital and digital to analog conversion.
