  • Patent number: 4160891
    Abstract: A furnace for the inductive heating of metallic workpieces with an induction coil body encompassing a furnace space through which workpieces on receivers are transported. The receivers are a pair of hollow tubes extending in parallel through the furnace space for receiving workpieces, the tubes being reciprocally moved backwards and forwards. A pair of rods having cam surfaces thereon extend through the space below the tubes so that rotation of the rods lifts the workpieces off the tubes during backwards movement.

  • Patent number: 4157567
    Abstract: The carrier is modulated over a definite frequency deviation range and is demodulated in an FM detector whose output voltage is used in an evaluation circuit to produce a switching pulse representing the dropout. The FM detector is constituted by a demodulator providing a digital output signal having a first value "1" within the deviation range and a second value "0" outside the deviation range. An evaluation circuit is connected to the demodulator and produces the switching pulse responsive to only the second value "O". The demodulator includes an retriggerable monoflop and an edge-triggered D flip-flop, and the FM carrier is supplied to the control input of the retriggerable monoflop and to a first control input of the edge-triggered D flip-flop. One output of the monoflop is connected to a second control input of the D flip-flop and the switching pulse is provided at one of the outputs of the D flip-flop.

  • Patent number: 4147569
    Abstract: A process for heating at least two metal pipes wherein each pipe is individually preheated in response to sensors detecting its initial temperature and wall thickness. The pipe then passes through a continuous heater which applies an equal amount of energy to each portion of the pipe, after which each pipe emerges having a predetermined temperature independent of both its initial temperature and the wall thickness.

  • Patent number: 4133145
    Abstract: A process is provided for producing a grinding agent carrier comprised of a carrier body and a layer of grinding agent on the surface of the carrier body. The grinding agent layer is initially produced on a planar substrate by sedimentation from a suspension comprised of a suspension medium and grinding agent, and the grinding agent layer is then transferred from the substrate and bonded to the carrier body. The substrate is maintained in a horizontal position and the sedimentation is effected on the horizontal substrate from a liquid column of the suspension wherein the liquid column has a height in millimeters which is at most around 0.4 times the square root of the width in millimeters of the liquid column.

  • Patent number: 4116799
    Abstract: A machine for simultaneously electrochemical processing a plurality of workpieces in which a workpiece receiver is mounted on spring loaded rails between a clamping unit and a base for horizontal movement between loading and operating positions. A working electrode extends through a bore in the clamping unit to create a working gap with a workpiece which is electrically connected via a spring loaded contact member to a source of eroding current. The clamping unit can be moved up and down to make and break electrical contact and to clamp and release the workpieces. Electrolyte is supplied to and removed from the working gap.

  • Patent number: 4101940
    Abstract: A composite input video signal, having blanking intervals and including line sync pulses increasing the amplitude of the input signal, is applied to the circuit, is amplitude filtered, and is split into a BA-signal, which is fed to an adding stage, and line sync pulses which are fed to a monostable multivibrator which converts the line sync pulses into output pulses having an amplitude within the amplitude range of the filtered video signal, and these output pulses are also supplied to the adding stage. The output of the adding stage is applied to the input of a storage controlled by a timing pulse sequence from a timing pulse generator. The output pulses of the monostable multivibrator are supplied to a phase comparator having an input connected to the output of the storage through a gating device. The phase comparator supplies a variable to the timing pulse generator to control its frequency.

  • Patent number: 4086462
    Abstract: A system for induction heating of workpieces which are transported touching or in close proximity through a succession of inductor coils along the workpiece axes. A grounded feeder supplies workpieces to the transporting structure and a grounded further processing machine receives the workpieces after heating. To eliminate sparking and corrosion problems, the AC currents fed to the coils are adjusted, for example by feeding currents in phase opposition to different coils, so that the potential along the direction of the workpieces from the first to last coil is substantially zero.

  • Patent number: 4085939
    Abstract: In order to effect repeated reworking of a body, whose tip, during use, engages a record carrier track to guide a playback or recording member along the track, the reworking involving subjecting the body to successive reworking operations after successive periods of use, the tip of the body being worn down to a certain extent during each period of use and material being removed from the tip to restore its original shape during each reworking operation, the useful life of the body is effectively increased by adjusting the maximum removal depth occurring during each successive reworking operation as a function of the depth to which the tip is worn during the corresponding preceding period of use.

  • Patent number: 4079222
    Abstract: A continuous heating induction furnace in which workpieces are mounted on a receiver for step-wise movement from a furnace inlet to outlet through a longitudinally extending chamber. A pair of lifter rods extend through bores at the chamber floor to engage the workpieces at each of a plurality of stops or stations and are in turn rigidly connected to a bar element extending below the chamber. The receiver reciprocates along the longitudinal direction while the lifter rods elevate the workpieces during backward receiver movement. The receiver is formed as a pair of tubes which engage bearings mounted at separated locations along the chamber so that the length of the chamber is not limited by the sag characteristics of the receiver.

  • Patent number: 4030296
    Abstract: A device for rotating a turbine, particularly during starting, comprises a positive displacement-type main oil pump which has a main pump suction which is connected to the discharge of a high pressure oil pump which also has a connection to supply oil to the bearings. An auxiliary oil pump is mechanically coupled to the high pressure pump and it is also hydraulically connected in series to the high pressure pump. When the pressure builds up between the high pressure pump and the main pump, the main pump may be driven as a motor by the high pressure pump to effect a turning of the turbine.
