Abstract: APPARATUS FOR CONVERTING AN A.C. INPUT SIGNAL    TO A RECTIFIED AND SMOOTHED D.C. SIGNAL     Abstract of the Disclosure Offset voltages of a precision rectifier circuit, buffer amplifiers, and an input comparator of a log converter are compensated for by charging a coupling capacitor to the combined total offset voltage of the apparatus.  The charging is effected by causing the comparator to operate as a unity gain inverting amplifier during part of the operating cycle of the log converter when the comparator output signal is not used, so that the log converter operation is not adversely affected.  During such charging the input of the precision rectifier circuit, to which the a.c. input signal is normally applied, is grounded.  Throughout the charging and associated switching operations a capacitor of a smoothing filter connected following the precision rectifier circuit is disconnected from ground to isolate the smoothing filter output from ground and to prevent switching transients from affecting the charge of this capacitor.     - i -

Abstract: Case 2737 FREQUENCY DETERMINING APPARATUS                ABSTRACT OF THE DISCLOSURE A frequency determining apparatus for receiving an input signal of unknown frequency and providing an output signal representing the frequency where the output signal is updated at substantially regular intervals regardless of the frequency of the input signal.  A frequency divider or prescaler divides the input signal by a factor n to give an adjusted signal. A gated counter counts stable clock pulses for a time period related to the period of the adjusted signal to give a count inversely related to the frequency of the adjusted signal.  A calculator corrects the count for the factor n and derives an output signal representing the frequency of the input signal.  The calculator also determines if the count has increased above an upper limit or decreased below a lower limit, and if so it changes the factor n accordingly to maintain the count and correspondingly the adjusted signal within a predetermined range.  The count is updated in accordance with the period of the adjusted signal which is main-tained within predetermined limits and consequently is updated at substantially regular intervals even though the frequency of the input signal changes greatly.

Abstract: ABSTRACT OF THE DISCLOSURE            A process is disclosed for sintering ferrous based powder parts.  The parts are heated to a sintering temperature at or above 1120°C (2048°F) for a period of at least 20 minutes in the presence of a flowing nitrogen atmosphere containing an admixture of about 5 to about 8% by volume endothermic generator gas which desirably controls decarburization of dissolved carbon promoting increased part strength.  Additional control of the dissolved carbon content in the sintered part can be preferably enhanced by the addi-tion of .4-.6% methane to the flowing nitrogen atmosphere. To avoid sooting of the parts due to the cracking of added hydrocarbons during heatup to sintering temperature with flowing atmosphere, the parts are preheated at a temperature between volatilization of the added hydrocarbon and 1250°F for a period of time to volatilize the added hydrocarbons in the powder parts prior to ascending to full sintering tempera-ture.

Abstract: Abstract of the Disclosure A joint sealing structure including an annular seal ring having a sealing portion provided with a sealing lip having a dynamic seal engagement with a joint member sealing surface at all times.  The sealing portion is carried on a connecting portion of the seal ring which, in turn, is provided with a base portion mounted in the counterbore of the seal space.  The stiffener is connected by a connecting portion to a base press fitted in the counterbore surface.  The base defines an inturned flange providing a bearing for a Belleville spring.  The Belleville spring is provided with a radial inner portion engaging projecting portions of the stiffener for biasing the sealing portion and lip thereof axially toward the sealing surface.  The diaphragm is a one-piece element including the stiffener, connecting and base portions and stiffener portion is molded integrally into the sealing portion of the seal ring.  The stiffener may be provided with a plurality of distributed openings for providing a positive mechanical bond of the molded sealing portion to the stiffener.  The Belleville spring may be arranged to pass over center in the range of axial movement between the joint members so as to provide an effectively flat spring rate and thereby provide a stabilized sealing force of the lip against the sealing surface.

Abstract: Abstract of the Disclosure Water-based hydraulic fluids and metalworking lubricants are disclosed which are thickened with a polyether polyol having a molecular weight of about 1000 to about 25,000 modified with an alpha-olefin epoxide having about 12 to about 18 carbon atoms.  Unexpectedly, synergistic thickening results from a combination of said polyether polyol with the com-ponents of the water-based hydraulic fluid or metalworking lubricant.  The particularly effective components of the hydraulic fluid or metalworking lubricant are the phosphate ester and water-soluble amine corrosion inhibitor components. The hydraulic fluid and metalworking fluids of the invention also contain a water-soluble polyoxyethylated ester of an aliphatic acid and a monohydric or polyhydric aliphatic alcohol, either one or both said acid and said alcohol being polyoxyethylated, a sulfurized molybdenum or antimony compound and a metal deactivator as well as other adjuvants conven-tional in this art.

Abstract: Hydraulic Servo Steering System Abstract A hydraulic servo steering system for vehicles has a steering valve for directing fluid to steering cylinders in response to pilot fluid directed to one end of the steering valve from a hand metering unit.  A servo cylinder directs a volume of fluid to the other end of the steering valve sufficient for returning the steering valve to its centered position in response to turning of the vehicle.  A pair of pilot operated check valves positioned in the lines between the servo cylinder and the steering valve are opened in response to fluid pressure being established in the lines by a means.  Should one of the lines rupture, the resultant drop in fluid pressure in the lines causes the check valves to close thereby isolating the steering valve from the ruptured lines.  Thereafter the steering valve can be operated in a "jerk steer" manner for emergency steering of the vehicle.

A filter is interposed in a space between the top of the hopper and the top of the stand, and is adapted to permit the passage of gas while filtering out abrasive particles entrained in the gas.  In order to assure that the opening is covered either by a glass sheet or other means when the apparatus is in operation, a safety means is provided so that the gaseous stream is directed through the hopper only when The opening is covered.
