Abstract: ABSTRACT          An input multi-level amplitude signal of 2M levels is supplied via a DC level controller to an AD converter for conversion into an N-bit (N being an integer greater than M) digital signal, and M high-order wits of the digital signal are provided as decided outputs.  It is decided by a decision means whether a deviation of the DC level of the multi-level amplitude signal at the input side of the AD converter is in excess of a predetermined value.  when the deviation of the DC level is decided less than the predetermined value, the outputs of bits less significant than the Mth bit in the digital signal are integrated for input as a DC level control signal into the DC level controller, correcting the deviation of the DC level.  When it is decided by the decision means that the deviation of the DC level is greater than the predetermined value r at least one of the M high-order bit outputs in the output digital signal is integrated for input as a DC level control signal into the DC level controller, correcting the deviation of the DC level.

Abstract: Abstract of the Disclosure A gas-blast switch,   preferably suitable for switching high voltages,  has two arc contacts which can be moved relatively to each other along an axis.    Also included are a heating volume and a compression volume concentrically formed around the axis.    Quenching gas  is compressed  in the com-pression volume by means of a compression slider. As soon as the gas pressure is sufficiently high, a part of the quenching gas flows via a back-pressure valve into the heating volume and there assists in blasting  an  arc  drawn  between  the  arc  contacts during  a  switching-off process.     The  assist  is needed a primarily  when  only  small currents  are involved  in  which  case  only  comparatively  low quenching gas pressure is developed in the heating volume.   The switing-off capacity of the gas-blast switch is increased with simultaneous reduction in the needed  actuating energy.   This is achieved in that the arc contact of a moving contact member has a discharge duct  which extends in axial direction from a free end facing a fixed contact member to another end which opens into the expansion volume. Between the compression volume and expansion volume a device  is provided for controlling the pressure and for refilling the quenching gas located in the compression volume.

Abstract: ABSTRACT OF THE DISCLOSURE    Disclosed is a furnace having a furnace chamber formed  with a work inlet and a work outlet,  and a work mount turntable rota-tably  provided within the furnace chamber,  the furnace  further comprising work carry-in means for carrying a work while mounting the  work thereon into the furnace chamber through work inlet  to transfer  the  work onto given one of work mount portions on  the turntable,  and work carry-out means for carrying a work  mounted on  one  of  the  the work mounts out of the  work  outlet  while mounting the work thereon.   Each of the work mounts,  the   work carry-in means,  and the work carry-out means is constituted by a plurality  of strip members disposed at regular intervals.    The respective  strip members of each of the work carry-in means  and the work carry-out means are arranged to move up and down passing through the gaps formed between the adjacent strip members of the work  mounts.  Thus,  a work can be mounted onto one of the  work mounts by causing the work carry-in means with the work  mounted thereon  to move down from a position higher than the work  mount to  a position lower than the same.   On the contrary,  the  work carry-out  means  can  lift a work mounted on one  of  the  mount portions  when the work carry-out means comes up from a  position lower than the work mount to a position higher than the same.

Abstract: Spike for use in connection with an implantable pace lead and for monitoring the pace conductor after implantation. The pace lead comprises a hollow, oblong lead containing coiled wire, which forms continuous windings. The spike comprises a stiffened elastic spiral, which at its leading end carries an axially symmetrical spherical tip. At the rear end the tip may advantageously be formed with an axially cylindrical recess, in the bottom of which the leading end of the spiral is fastened.  When introducing the spike into the lead of an implanted pace lead for monitoring purposes, the tip, by virtue of its shape, is prevented from becoming caught in the channels between the windings of the coiled wire, since it moves around the bends, which may be formed in the lead during insertion into a blood vessel. Insertion is thereby facilitated. <IMAGE>
