Abstract: ABSTRACT OF THE DISCLOSURE         A clock extractor is disclosed in which an input data signal is sampled and held in accordance with a sampling frequency, the input data signal thus processed is subjected to equalization and amplification, a dif-ference in voltage (namely, height) is detected between those portions of a waveform obtained after the equaliza-tion and amplification which appear before and after a time when the waveform has a maximum voltage amplitude, a phase of that portion of the waveform which has the maximum voltage amplitude, is determined by making the above-mentioned difference equal to zero, and a clock signal synchronized with the portion having the maximum voltage amplitude is extracted and reproduced from the input data signal.

Abstract: ABSTRACT OF THE DISCLOSURE      A valve system includes features to control flow of fuel between a pair of fuel tanks during a transfer opera-tion so as to prevent flow of return fuel from a carburetor back to a previously filled tank.  The valve system includes a pair of valve bodies each having two mechanically operated sealing elements therein.  One of the valve bodies has larger inlet and outlet ports to control the supply of fuel from the source tank of the system to a vehicle carburetor. The other of the valve bodies has smaller ports to control the flow of excess fuel flow to the selected source tank of the pair of tanks during engine operation.  Each of the valve bodies includes a push rod operatively connected to a single motor drive yoke element.  Each sealing element is spring biased and has an insert directed therethrough constituting a seal carrier slidably supported on the push rod.

Abstract: SOLDERING APPARATUS FOR  PRINTED CIRCUIT BOARD   Abstract of the Disclosure An improved soldering apparatus for printed circuit boards includes a first solder tank and a second solder tank provided adjacent each other for storing molten solder.  A first nozzle and a second nozzle independent of each other are disposed in the first and second tanks, respectively, and serve to spout molten solder.  A printed circuit board is passed sequentially and at an upward incline through solder waves from the first and second nozzles.  The arrangement is characterized in that the second nozzle is disposed at a level above that of the first nozzle, the level of the molten solder in the second tank also being disposed higher than that in the first tank.  The arrangement provides improved soldering and enables ready adjustment of the optimum spouting heights.

Abstract: INVERTER WITH IMPROVED  POWER FACTOR CONTROL        Abstract of Disclosure There is provided an improvement in a power inverter for converting D.C. voltage into an alternating voltage by alternat-ing gating D.C. current across a load.  This type of inverter employs a gating circuit for providing gating signals in two sets of switches at a frequency which controls the power factor of the voltage and current applied to the load, means for detect-ing the power factor, means for comparing the detected power factor with a reference signal indicative of a desired operating power factor and means for adjusting the frequency in accordance with the comparison whereby the power factor tends to be at the desired power factor level.  The improvement in this type of in-verter is the provision of means for changing the reference signal during the operation of the inverter in accordance with a control signal so that the desired power factor can be changed during start up of the inverter.

Abstract: SEAT AND CONTROL LEVER INTERLOCK           ABSTRACT OF THE DISCLOSURE A seat and hydraulic control lever interlock for lift trucks in which access to a battery compartment is in part enabled by pivoting the operator seat forwardly over the steering wheel, which pivotal movement causes interlocking lever means between the seat pivot and hydraulic control levers to actuate to an armed position.  Forward pivotal movement of the control levers to an inoperative position to clear the battery compartment allows the lever means to move to a position in which the control levers are held in such inoperative position until the seat is pivoted rearwardly over the battery compartment.

Abstract: Abstract of the Disclosure The disclosure describes a traction device for mounting on a tire without having to remove the hub cap of a tire wheel on which the tire is mounted.  The device comprises a plurality of radially extending arms which are pivotally connected at their inner ends to a common connector and a hook formed at the other end of each arm, the hook being shaped to embrace the tread surface and at least part of the side-walls of the tire.  The hook has means thereon to define a friction plate.  The device is so constructed that when it is mounted on a tire, the common connector and the inner ends of the radial arms are spacedly and outwardly centrally aligned with respect to the hub cap of the tire wheel for easier mounting.  Finally, the arms are tightened together so as to prevent slipping of the hooks over the tread surface when the tire rotates.
