Abstract: MANUALLY OPERABLE TOOL FOR INSTALLING                    BLIND ANCHOR NUTS          Abstract of the Disclosure A manually operable tool for installing blind anchor nuts by pulling an internally threaded part of the nut into a body part of the nut to expand the latter.  The tool includes a body member having a bore extending therethrough, an anvil at one end of the bore for engaging the body part of an anchor nut, the anvil surrounding an aperture aligned with the bore, and a grip by means of which an operator can hold the body member to prevent rotation thereof about the bore.  A mandrel, which may be changed without the need for external tooling, is positioned in the aperture in the anvil, the mandrel having an externally threaded portion extending outwardly of the anvil and a socket facing into the bore.  A shaft is rotatable and reciprocable in the bore of the body member which shaft is provided at one end with a key which fits into the socket on the mandrel in driving engagement therewith, the key being interchangeable without the need for external tooling.  The shaft is provided with a handle outside the body member of the tool by means of which the shaft can be both rotated and reciprocated with respect to the body member, the shaft being reciprocable between a first position in which key on the shaft engages in the socket on the mandrel thereby allowing rotation of the mandrel by means of the handle, and a second position in which the key disengages from the socket there-by allowing rotation of the handle without rotation of the mandrel.

Abstract: TORQUE RESPONSIVE SHUTOFF MECHANISM            FOR POWER TOOL              ABSTRACT OF THE DISCLOSURE     A fluid power tool having a torque responsive energy absorbing, nondisengaging drive mechanism interconnecting a motor and a driven spindle.  The mechanism includes a driven member coupled to the spindle and a driving member connected to the tool motor and yieldably biased toward the driven member.  The driven member has a plurality of spiral ball grooves disposed on the circumference thereof.  The driving member has cooperable axial recesses.  Bearing balls disposed in the recesses and grooves form a driving connection between the two members.  The ball grooves are spirally sloped such that a preselected torque between the two members results in the rotation and axial translation of the driving member rela-tive to the driven member.  The axial translation of the driving member effects the release of a valve rod which actuates a valve to shut off the motor.  The kinetic energy causing relative rotation after shutoff of the motor is stored and dissipated by springs.

Abstract: ABSTRACT OF THE DISCLOSURE:         A process of removing arsenic and/or antimony from substantially organic liquids which are formed by the carbo-nization of oil shale or during the upgrading of fossil fuels, such as the gasification, pyrolysis or hydrogenation of coal, comprising a heat treatment of said liquids under superatmospheric pressure and a subsequent removal of the solids, characterized in that the liquid which contains oil shale dust or coal dust and possibly also ash particles is subjected to a treatment under a total pressure of 30 to 160 bars and at a temperature of 250 to 450°C whereby elementary arsenic and/or antimony is caused to be deposit on the solids, and the deposited elementary arsenic and/or antimony  is subsequently  separated  from the liquid jointly with the solids. The advantage offered by the invention resides particularly in that a simple process is is provided by which arsenic and/or antimony can  be removed from substantially organic liquids formed by the carbonization of oil shale or coal or by the gasification of coal. Another advantage offered by the process according to the invention resides in that arsenic and/or antimony is removed even without an addition of extraneous hydrogen and particularly in the presence of a dehydrogenating catalyst.          Under the hydrogenating conditions used within the scope of the invention there is no loss of carbon due to a cooling of oil.

Abstract: ABSTRACT OF THE DISCLOSURE A tuning system for a television receiver includes fine tune memories and tuning information memories having reference channel nominal tuning information for each frequency band and nominal tuning information for each channel.  Accumulator means subtract the nominal tuning information for a selected channel from the nominal tuning information for an adjacent channel to derive a slope factor for the channel.  The slope factor is used to equalize an auxiliary tuning voltage source.  Control logic, including channel number counters and latches and state counters, is coupled to the accumulator means, tuning information memories and the fine tune memories.  The memories' and accumulator means' outputs are coupled to a corresponding plurality of comparators which are also coupled to counters for deriving pulse-width modu-lated (PWM) signals corresponding to tuning information in the accumulator means and memories.  The PWM signals are supplied to a tuning voltage generator where they are combined to produce the final tuning voltage for the tuner.  The final tuning voltage con-sists of the nominal tuning voltage combined with the product of the fine tune voltage and the derived slope factor.

Granted: 1982-08-24
Abstract: NOISE PROTECTION CIRCUIT FOR AM STEREO COSINE CORRECTION FACTOR                         ABSTRACT     The cosine correction factor of a receiver for com-patible AM stereo reception is controlled by the amount of high frequency energy present in the demodulated signal. Large amounts of such energy indicate a low signal to noise ratio and cosine correction under such conditions is then not desirable.  During periods of excessive high frequency energy, a filter circuit output causes a switching circuit to remove the derived cosine correction factor and cause division of the demodulated signal by a factor of one instead.

Abstract: ABSTRACT A modular wiring system is disclosed useful for lighting and power distribution in office buildings, fac-tories and the like.  The modular wiring system is distin-guished from the prior art by use of a five-face connector assembly as its principal component for the distribution and control of power to lighting fixtures and power recep-tacles.  The connector assemblies may be one of four types for providing different power configurations at the connector faces.  The five-face connector assemblies all utilize the same housing and are economical to manufacture by using specially designed bus bars to obtain the desired power configurations and to provide the terminal connections. Other components of the wiring system mate with the five-face connector assembly to provide an efficient lighting or convenience power system which may be easily field modified.

Abstract: REMOTE TRANSMISSION LUBRICATION SYSTEM               Abstract of the Disclosure A tractor transmission is provided with a clutch housing containing an oil reservoir vented to the main transmission which is vented to atmosphere.  A transfer pump is disposed in the clutch housing to pump an oil-air mixture from the reservoir to the main transmission housing.  A portion of the pumped oil-air mixture is diverted through a line of a predetermined size to lubricate the front differential.  When the oil reaches the front differential, it is diverted to the left and right final drive gear spaces separated by left and right walls from the diff-erential gears.  The oil in the final drive spaces increases in height until it passes through either the bearings supporting the differential housing or through the center of the differential pinion gears to the differential gear space.  Holes in the left and right walls provide maximum levels of oil in the final drive spaces.  When the oil spills over into the differential gear space, it lubricates the differential gears and then passes into a baffle and an overflow line which is located below the center line of the differential.  The baffles separate the oil from the air and the pressure of the air in the sealed differential forces the oil through the overflow line back to the reservoir in the clutch housing.
