Abstract: ABSTRACT OF THE DISCLOSURE     Ignition control signals for a multipulse controlled rectifier are combined in a sequence which is fed through a first time delay stage to a phase control circuit having a voltage-controlled oscillator which generates a phase-locked, gated, highly accurate square-wave oscillation as a trigger pulse series.  The ignition control signals and the trigger pulse series of the vol-tage-controlled oscillator are conjunctively coupled in blocking gates and then amplified to form firing (ignition) pulses.  A second time delay stage is pro-vided for safety, in the event of dynamic control processes, and follows the first time delay stage.  The output signals of the second time delay stage are linked to the ignition control signals in additional blocking gates and are subsequently amplified.  Should the phase control circuit be unable to follow the changes of the ignition control signals in the event of dynamic changes in the control processes, the ignition pulse formed after the response delay of the second time delay stage is utilized.

Abstract: ABSTRACT      The manufacturing  of  at least one photothermal converter  ele-ment  according to the invention consists  essentially of  implanting a multiplicity of substantially uniformly distributed parallely pro-jecting transparent fibers  (4)  onto a baseplate element  (1) provid-ed with an absorbing coating  (2)  of a normally solid material capa-ble of being temporarily converted to a plastic state, thanks to the use of an array of guiding means  (5, 6, 7) arranged above the base-plate element. The implantation proper of the desired fiber struc-ture is then performed by advancing a series of bundles  (10) of fi-bers  (4)  through the array of guiding means,  to the desired level above  the  baseplate  element,  and  by clipping the  advanced bundles to the desired length above the guiding means  (5, 6, 7), so as to cause the  falling with limited transverse spreading of the clipped fibers onto the coating of the baseplate element. This coating be-ing concurrently converted to its plastic state, the clipped fibers are then caused to adhere to the plastic coating, which is then so-lidified so as  to firmly secure the adhering fibers. The array of guiding means  (5, 6, 7)  is finally withdrawn from the firmly secur-ed  fiber  structure.  The  baseplate  element  thus provided with such a firmly secured fiber structure thereby constitutes a photothermal converter element.     Fig. 1

Abstract: SPECIFICATION     Title of the Invention SYNTHESIS OF UREA            Abstract of the Disclosure The specification describes a process for synthe-sizing urea.  The process comprises reacting ammonia and carbon dioxide in a molar ratio of 3:1 - 5:1 and at a pressure of 150 - 250 Kg/cm2G, subjecting the resultant reaction mixture to a stripping step using gaseous carbon dioxide at a pressure substantially equal to the urea synthesis pressure and a temperature of 195 - 210°C to remove unreacted ammonia and unreacted carbon dioxide contained in the reaction mixture so that the content of unreacted ammonia is lowered to 10 - 15% by weight.  This invention ensures a high conversion ratio from carbon dioxide to urea, considerably little formation of biuret during the stripping step, and reduced consumption of high pressure steam.

Abstract: ABSTRACT     To  reduce  the  number  of  different  software  packages required for document controlled  systems  of  the  type  used  in automated  fueling systems, automated bank teller systems, and the like, a "format" character is encoded in a preestablished location on  the  card used to activate the system.  Typically, the system activation cards include an  identity  section  having  a  maximum number  of  characters  in it which may be utilized to perform the identity function. Different  system  users,  however,  frequently divide  this  identity section into different formats of groups of characters separated by "space" characters.   Insertion  of  space characters  into  the  encoded  identification  field on the card, however, uses valuable space which otherwise may be  required  for the  full  identification  functions in the system. By employing a separate format identity character, a wide variety of formats  may be  possible  while  using  all  of the characters possible in the identity field  for  their  chosen  function.    The  system  then processes the  data  in  response  to  the  format  character  in accordance with the decoding  of  that  character  to  insert  the necessary "space" characters into the message process prior to its application to a suitable utilization circuit  or  device.    When this  function  is  implemented  into  software, a single software program  may  be  universally  used  with  a   large   number   of applications  of the system instead of the previous requirement of a different software package for  each  different  message  format required by different customers or users.

The body includes two laterally spaced  bores,  counterbored  from  one  end,  which counterbores bear enlarged peripheral recesses inter-mediate of their ends,  Cylindrical plungers sized to the counterbores and having a radially enlarged collar intermediate of their ends, in excess of the diameter of  the  counterbore  but  less  than  the  peripheral recess, are slidably mounted therein with the collar positioned in the radial recess.  A coil spring sized to  the peripheral  recess is compressed between the collar and one end of the radial recess to spring bias the plunger away from the bore.  An O-ring seal whose outside diameter is approximately equal to that of the radial recess is positioned on the plunger to the side of the collar opposite that of the coil spring.  The end of the plunger facing the bore carries a reduced diameter  portion  acting  as  a  male  contact  which slidably fits into a small diameter axial hole within the  facing end of a  female contact having a base portion  sealably  carried  within  the  bore  of  the receptacle body.   A plug bears male contact prongs which project into female contacts formed within the end of the plunger opposite the compression spring. The plug locks to the cuff when the plug male contact prongs mate with the female contacts of the plungers, and the plungers are forciably displaced against the bias of the springs to engage their male contact ends with the axial holes within the fixed female contacts to complete a two part electrical connection through the plug and between the electric motor driving a scrubber mechanism of a vacuum cleaner vacuum pick up head and an electrical source at the opposite end of the hose.

Abstract: ABSTRACT OF THE DISCLOSURE          An arrangement is disclosed for cutting and guiding the marginal strip separated in connection with the lead-in opera-tion of a paper web from this web.  The arrangement consists of jet tubes connected to a compressed air supply, of nozzle aper-tures provided on said jet tubes and of plates guiding the running of the marginal strip. The nozzle  apertures or slit of the first jet tubes are directed to blow air jets parallel to the first guide plate.  The nozzle apertures of the second jet tube are dis-posed to blow air jets parallel to the second guide plate.  The planes of the guide plates are set at a given angle with reference to each other so that the orientation of the first guide plate is consistent with the direction in which the severed end of the mar-ginal strip is conducted onward, and the orientation of the second guide plate is consistent with the direction in which the marginal strip is conducted into the pulper.  The guide plates operate with the aid of the air jets provided in conjunction with them as guid-ing and air transport surfaces so that as the air jets pull the marginal strip in different directions in the area of the guide plates, the marginal strip will break by tearing at a point between the guide plates or at the nozzle apertures.  The new end obtained after cutting off the marginal strip is conducted onward under guidance by the first guide plate.
