Abstract: REMOVAL OF TOXIC AND ODOROUS ORGANICS FROM WASTE WATER BY SATURATED ACTIVATED CARBON            ABSTRACT OF THE INVENTION         An adsorption process for the selective removal of naphthalenic hydrocarbons in the waste water from a petrochemical operation which comprises contacting the effluent waste water for relatively short periods with activated carbon which has become saturated with respect to non-naphthalenic organics.  Contact of the waste water streams with the saturated carbon is continued until the breakthrough of naphthalenic compounds in the waste water exceeds a predetermined concentration, such as 2ppm.  It has been found that efficient removal of naphthalenic com-pounds can be effected by contacting the waste water for relatively short contact times, for example 10 minutes, notwithstanding the fact that the activated carbon has previously become saturated with respect to non-naphtha-lenic compounds.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention is a package for radiation triggered semiconductor devices and a method for directing radiation to the radiation receiving region of a semiconductor device mounted in such a package.  The package is of the type which has a side wall formed of an electrically insulating material surrounding a central cavity, and top and bottom walls formed of conductive material.  The package is hermetically sealable and constructed to withstand externally applied compression.  The means and method for radiation triggering of a semiconductor device in the package include optical conduit means extending through and hermetically sealed to the insulat-ing side wall of the enclosure.  Radiation is caused to enter the package along a first optical path in said optical conduit means.  A prism or other similar means in the cavity redirects the radiation from the first optical path toward a predetermined region in the cavity to trigger a radiation triggered semiconductor device mounted in the package.

Abstract: TITLE                  PLASTIC VALVE ASSEMBLY                 ABSTRACT OF THE DISCLOSURE      A molded polyethylene valve body having a conduit portion and an annular portion extending upwardly from the conduit portion.  A passageway extends through the conduit portion for the conveyance of fluid.  A valve seat is formed in the conduit portion by a metal sleeve that is molded in the valve body to prevent separation of the sleeve from the valve body during sustained pressures.  O-rings positioned in grooves around the metal sleeve are compressed by the plastic material during the molding process to effect a seal between the sleeve and the plas-tic valve body.  An annular rubber sleeve insert is vulcanized onto the inner diameter portion of the metal sleeve.  A plastic valve disc is centrally positioned in the conduit portion within the periphery of the rubber sleeve insert and is arranged to sealingly engage the rubber sleeve insert when the valve is moved to the closed position.  A metal stem extends through the annular portion of the valve body and is connected to the valve disc.  The upper end of the metal valve stem is molded into an actuator.  The actuator is sealingly connected to the annular portion of the valve body so as to maintain the actuator on the valve body in the event that the pressure seal between the valve disc and the valve body is destroyed.

Abstract: Abstract A three-transducer SAW filter is disclosed that in-cludes a central input transducer requiring only one-half of the interdigital fingers normally required by prior art three-transducer SAW filters.  As a result, two input trans-ducers may now be provided in the space normally occupied by one prior art input transducer.  The only requirement is that each input transducer have an axis of symmetry about which surface waves are propogated symmetrically.  Since each input transducer may have a different frequency re-sponge, a dual-passband SAW filter may now be provided in the space normally occupied by a single prior art SAW fil-ter.  Furthermore, a multi-passband SAW filter may be pro-vided by arranging pairs of input transducers between three or more output transducers which are electrically coupled in parallel.  In addition, the input and output connections of a multi-passband SAW filter may be interchanged such that an input signal, applied to the parallel connected output transducers is frequency sorted by the passbands of each of the input transducers.

Abstract: ABSTRACT OF THE DISCLOSURE         A thrust producing shoe sole and heel having fluid-proff cavities respectively located in the heel portion and in the sole portion which underlies the metatar-sal ball area of a foot for which the sole and heel is sized, the two cavities being connected by a restricted passageway.  The material underlying the two cavities at the bottom of the sole and heel is resilient and wear-resis-tant.  Fluid, either gas or liquid, is contained within the cavities and passageway in such pressure and amount as to cause bulges below the normal bottoms of the sole and heel, whereby at rest a foot on the sole and heel is cushioned confortably on the fluid in the bulges, and in walking fluid under bulge producing pressure alternates through the passageway between the two cavities, producing shock absorp-tion and an alternate lifting effect by the bulges which provides forward thrust both in the heel portion and the metatarsal ball area that facilitates walking.

Abstract: ABSTRACT A radio transmitter for use in a mobile communication system is disclosed.  To maintain the radio signal intensity at the base station within prescribed limits it is necessary to control the transmitter power output to compensate for varying distances between the mobile unit and the base station. Typically, the conventional control circuit comprises a power amplifier, a directional coupler coupled to the power amplifier, a detector detecting the forward power of the coupler, a generator generating a difference voltage between the output voltage of the detector and a reference voltage and a power regulator to regulate the output power of the power amplifier in response to the difference voltage.  The transmitter power is changed by varying the reference voltage in response to control signals.  A disadvantage of the conventional system is that it has a narrow range in which the output power is controllable.  According to the invention disclosed, additional circuitry is provided for varying electrically the coupling coefficient of the directional coupler, thereby extending the con-trollable range of the transmitter output power.

Abstract: COMPARATOR CIRCUIT AND METHOD          Abstract of the Disclosure A magnitude comparator circuit is provided for determining the largest binary number, out of a plurality of binary numbers received bit-serially, in parallel.  A latch is used to store the results of the comparison and is initialized to an all logic 0 state.  The latch has a unique one-bit location corresponding to each number being compared, and a logic O stored in the latch indicates that the number corresponding thereto is still in contention (i.e remains a candidate) for being the largest, and a logic 1 indicates it has been eliminated from contention. As the numbers are received bit by bit (most significant bits first) the bits are applied to gating circuits, one for each number, which invert the bits and store the inverted result in the latch.  The exceptions to this are twofold; a) when a number has already been eliminated from contention, as indicated by a logic 1 stored in the latch corresponding to that number, it remains a logic 1; and b) when the remaining candidates all have a binary 0 in an equal significant bit location no choice is of course possible and the aforestated inversion does not take place and the contents of the latch are simply recycled.                             -i-
