Patent CA-1174110-A (CA)
Inventor: NAGEL GERHARD
IPC: B41K3/60
Filed: 1981-09-04

Abstract: ABSTRACT The invention relates to a device for accommodating an ink rol-ler having a circular cylindrical ink carrier body and end discs disposed at the end faces thereof.  The diameter of these end discs is larger than that of the ink carrier body.  Such ink rollers are used in printing mechanisms to ink the print types before carrying out the actual printing operation. To facilitate the handling of such ink rollers, especially when replacing a used ink roller with a new ink roller, and to avoid soiling the fingers or clothing of the operator, the device contains two U-shaped shells (2, 3) connected together, their width at their open ends being equal to the width of the ink roller to be accommodated.  The depth of these shells (2, 3) is equal to the diameter of the end discs of the ink roller to be accommodated and the shells (2, 3) have at both sides regions (16, 17, 18, 19) which act as clamps for the end discs, whereby the width of the one shell (2) is con-stant over its entire depth, while the depth of the other shell (3) in-creases from the open end in the direction towards the closed end.  The de-vice makes it possible to take a used ink roller out of the printing mech-anism and to insert a new one without having to touch the ink roller with the fingers.  The used ink roller remains in the device in a relatively pro-tected position.

Each of the switching blocks includes a multiplicity of line terminators each adapted to be connected to a data terminal.  In each switching block there are provided  (1) a central processing system for establishing   communication links associated with a respective call, (2)  a communications controller for controlling local data exchange between pairs of line terminators connected thereto across real channels, (3) a virtual channel controller for controlling remote data exchange across virtual channels to different switching blocks and (4)  interface units arranged between the virtual channel controller and a respective one of the interconnecting lines.  The virtual channel controller may be understood as a main transfer control unit not only for switching data and control information from any one of the control devices connected thereto and the others, but also for processing control information for redirecting received data.

Abstract: Abstract:     A process and apparatus using airborne equipment for monitoring the current level in a pipeline includes flying an aircraft bearing at least one AC magnetometer above an underground pipeline.  The magnetic field created by a DC current impressed on the pipeline is detected and extraneous signals other than those created by the magnetic field of the pipeline are filter out.  The linear position of the magnetometer with respect to the pipeline is detected as the aircraft is flown and a discernible record of the magnitude of the magnetic field in relation to the linear position of the magnetometer with respect to the pipline is produced.  The technique is cheaper and more reliable than those previously proposed for the purpose.

Abstract: ABSTRACT OF THE DISCLOSURE Methods and compositions for assaying for coenzymes having N-substituted 1,4-dihydropyridyl as the active portion of the prosthetic group.  The conversion of NAD to NADH is widely measured both for determining NAD-NADH (including the analogs thereof) dependent enzymes and enzymes that can be coupled to NAD-NADH dependent enzymes, and for determining ligands or receptors in competitive protein binding assays. Antibodies specific for NADH in the presence of NAD are employed, providing enhanced fluorescence over the normal fluorescence of unbound NADH.  By determining the rate of formation of NADH or the concentration of NADH, the analyte or enzyme of interest can be determined.

Abstract: UNITED STATES PATENT APPLICATION               BY:    CARL E. ECKMAN               FOR:   PROCESS FOR FORMING COAL-OIL  MIXTURES UNDER SELECTED CON-DITIONS OF TEMPERATURE AND SHEAR                 ABSTRACT OF THE DISCLOSURE          An  improved  technique  is  provided  for  forming  coal into a stabilized coal-oil mixture.  Coal, in a fine mesh size, is admixed with oil, a monomeric compound, a reaction initiator and a reaction catalyst at elevated temperatures and under  a condition of low shear.  The coal mixture is thereafter immedi-ately subjected to a condition of high shear at the maintained elevated  temperature.   The  mixture  is  then  admixed  with  a gelling agent to form a stable coal-oil mixture.  According to the technique, coal of significantly greater water content than heretofore thought acceptable,  is formed to a stable coal-oil mixture  in  a  ready  manner.   In  addition,  the  amount  of monomeric compound  heretofore  thought  needed  to  form  the desired stable mixture  is  substantially reduced,  resulting  in improved process efficiency.

Abstract: ABSTRACT OF THE DISCLOSURE     A method of and a protection relay for protecting electrical equipment.  The method includes dividing a prede-termined dividend value by a signal corresponding to the load current in the equipment to provide a quotient signal, and then linearly integrating the quotient signal.  When the integrated signal reaches a predetermined value, the equipment is tripped.  This provides an overload vs tripping time charac-teristic which is substantially linear.  The method further provides for sensing  whether the equipment is operating in a start up mode or in a normal running mode, and then automatically to select a less sensitive overload vs tripping time charac-teristic when the equipment operates in the start up mode and automatically to switch to a more sensitive characteristic when the equipment reverts to its normal running mode.

Abstract: Method of Producing Metallic Nickel Abstract A method of producing metallic nickel from a nickel--bearing ode material comprises producing a plasma jet by passing a reducing gas through the zone of electric discharge, heating this material by the plasma jet to the nickel melting temperature. In the course of heating nickel oxides are reduced to metal, and iron and cobalt oxides contained in the nickel-bearing oxide material are partially reduced with the resultant formation of a melt of metallic nickel. The reduction of' nickel oxides to metal is effected in the presence of reducing gas fed in an amount ranging from about 1.2 to 1.75 times that of the reducing gas required in accordance with stoichiometry. In addition, the method includes desulphurization of the resultant melt of metallic nickel and its subsequent refinement by removing therefrom the gases dissolved in the melt and incompletely reduced iron and cobalt oxides.

Abstract: SHAFT SEAL ASSEMBLY          ABSTRACT OF THE DISCLOSURE      An annular seal assembly disposed between a shaft surface and a surrounding housing, for example, a seal assembly for an aft-stern tube seal of a sea-going vessel, comprises a nonrotating annular seal element having a circumferentially segmented construction, the segments having overlapping ends.  An inflatable annular member, concentrically disposed between the housing and the seal element, sealingly supports the seal element on the shaft surface at the same time providing some freedom for radial vibration movements to accommodate shaft-eccentricities and radial vibrating movements of the shaft.  The seal assembly includes means to admit a controlled pressurized fluid into the inflatable member.  The pressurized fluid may be the outboard sea water or any water or air under pressure. The pressurized fluid is so controlled as to maintain a narrow clearance between the shaft surface and the segmented seal element for a lubricant, regardless of seal wear and variation in the pressure head of the fluid.  The segmented seal construction offers better performance over conventional nonsegmented types.
