Abstract: Abstract The object of the description is a phase-locked loop circuit comprising e.g. in the form of an integrated circuit (IC) in se-quential connection a digital phase comparator, to the input of which are supplied a reference frequency (fref), a loop filter and a voltage-controlled oscillator, from which a feedback branch is fed to the second input of the phase comparator.  The voltage (.PHI.V; .PHI.R) of the pulses obtained from the digital phase comparator is disposed so as to be adjustable, thus enabling to modify the li-miting frequency and rate of the loop.  The adjustment of the vol-tage of the pulses can be carried out e.g. by adjusting the supply voltage of the phase comparator or by means of an exterior diode or transistor cutter (Q2, Q3).  The circuit is usable e.g. in ra-dioelephone applications, in which a rapid loop is connected du-ing channel switch.

Abstract: Abstract of the Disclosure An adjustable infeed ramp supports the input end of a main frame at a height to tilt the main frame to correspond to the inclination of a log in process.  Pulled into the machine by a winch line, the leading end of the log is gripped by vertical feed rolls on a pair of side squeeze arms, a horizontal feed roll on a top squeeze arm and then by a horizontal top feed roll of hourglass shape just ahead of a vertical transverse shear blade.  In a first operation the shear blade cuts less than entirely through the log and then moves away from the input end of the main frame, sliding the log, assisted by the feed rolls, farther into the machine.  This movement pushes the leading end of the log through an adjustable splitter head assembly capable of splitting the leading end portion into two, three or six pieces, as desired.  A second operation of the shear blade cuts off the leading end of the log and the shear blade returns back along the main frame to its starting position to repeat the cycle on another section of the log.

Abstract: ABSTRACT OF THE DISCLOSURE      A sealing structure for providing a relatively leak-proof seal between the junction of two gaskets which are disposed at an angle relative to one another is disclosed.  A first gasket is interposed between two pieces of a first component of a vehicle engine or other device.          When the two pieces are assembled together, the first component defines a surface adapted to mate with a corresponding surface formed on a second component of the device.  An edge of the first gasket extends beyond the mating surface of the first component.  The edge of the first gasket includes a plurality of outwardly extending projections formed integrally therewith.  A second gasket is interposed between the mating surfaces of the first and second components.  The second gasket includes a plurality of recesses formed in a face thereof, each of which corresponds to one of the projections formed in the first gasket.  When the first and second components are assembled together, the projections formed on the edge of the first gasket extend into and engage the recesses formed in the face of the second gasket.  The cooperation of the first and second gaskets prevents the formation of a flat surface abutment therebetween so as to provide a relatively leak-proof seal.

Abstract: ABSTRACT     A method and apparatus for electroslag surfacing of metal plate which utilizes a plate feeder assembly to which the  plate  is  presented  and  which  includes  an  elongate, horizontally  disposed  feeder  table  having  an  approach-end section and a runout-end section.   The plate,  with  a major surface uppermost,  is  conveyed along the feeder table in a feeding  direction  from  said  approach-end  section  to  said runout-end  section,  and  is  subjected  to  an  electroslag operation  at  a  surfacing  installation  located  intermediate those  sections  to  provide  a  cladding  metal  layer  on that surface.  At the surfacing installation, there is a flux mould arrangement  under  an  electrode  holder  and  feeder  assembly having  depending  electrodes  vertically  in  line  with  the interior of the mould arrangement.  The plate is passed under the mould  arrangement  and the  electrode  holder  and  feeder assembly is vertically adjusted to bring a lower end of the electrode means into contact with the upper  surface and  to establish current  flow.   On establishing current  flow,  the electrodes then are raised to establish an  arc between the electrodes and the uppermost surface, with charging of flux to mould  arrangement  establishing  a  molten  slag  pool  which overlies that surface to submerge and extinguish the arc. Alloy powder material to said mould arrangement at the interface between the slag pool and the uppermost surface and melted in said mould arrangement to clad the uppermost surface as the metal plate is conveyed under the mould arrangement.
