Abstract: ABSTRACT                         GLOW PLUG      The invention is a method of making a pressure tight seal for a glow plug characterized by applying a high current to heat a groove (31) in the outer shell (3) of a glow  plug  while  simultaneously  pressing  together  the sealing elements adjacent the groove i.e.  an insulator (2), a gasket (1), the flared end (42) of a protective tube (4) and a shoulder (32) within the shell (3).  The groove (31) concentrates the heat and allows the shell to be compressed around the elements of the seal.

Abstract: ABSTRACT In a method of solvent recovery from a solvent-containing hydrocarbon phase by flash vaporization in two successive separation stages at different pressures, an improvement may be obtained by introducing an intermediate pressure separation stage having an operating pressure in the range of 1 to 4 bar, that is between the pressure range of the low pressure stage (0.1 to 1 bar) and the pressure range of the high pressure stage (4 to 10 bar).  The energy required to effect solvent recovery is reduced by conducting the vaporization in three pressure stages rather than two.

Abstract: Abstract of the Disclosure Magnetically actuated devices such as, e.g., switches and synchronizers typically comprise a magnetically semihard component having a square B-H hysteresis loop and high remanent induction.  Among known alloys having such properties are Co-Fe-V, Co-Fe-Nb, and Co-Fe-Ni-Al-Ti alloys which, however, contain undesirably large amounts of cobalt.      According to the invention, devices are equipped with a magnetically semihard, high-remanence Fe-Cr-Mo alloy which comprises Cr in a preferred amount in the range of 6-26 weight percent and Mo in a preferred amount in the range of 1-12 weight percent.  Preparation of alloys of the invention may be by a treatment of annealing, deformation, and aging.          Magnets made from alloys of the invention may be shaped, e.g., by cold drawing, rolling, bending, or flattening and may be used in devices such as, e.g., electrical contact switches, hysteresis motors, and other magnetically actuated devices.

Abstract: ABSTRACT     A method for aligning the drill stem and bit of a rock drill rig when starting the drill wherein the applied feeding power on the drilling machine of the rig has results in deflection of the direction of the drill stem by deformation of the articulated and extensible drill boom of the rig and of the pivotally supported drill support on the drill boom.  The drill rig is of the type which comprises elements for measuring boom lengths and articulation angles, servo means for controlling the lengths and angles and a control unit connected to the measuring elements and servo means for adjusting the drill stem and bit.  The various articulation angles which are required to compensate for deformation of the drill boom and drill support are determined as if the drill boom and support were in unloaded condition, using measured values of the boom lengths and articulation angles, set in the control unit in unloaded condition.  The adjusted articulation angles are corrected to the determined articulation angles when feeding power is applied.  Thus, the drill stem and bit become correctly positioned and directed in the loaded condition also.  Apparatus for carrying out the method may comprise a computing device including a mathematic model with a definition of the changes for the articulation angles.

Abstract: DUAL COUPLER FIBER OPTIC RECIRCULATING MEMORY           Abstract of the Invention A  fiber  optic  recirculating  memory  is  disclosed which  utilizes  dual  couplers  to  form  a  splice-free recirculating memory device from a length of single mode optical fiber forming a loop which acts as a delay line and a second length of single mode optical fiber which provides  an  input  end and  an  output  end  for  the device.   A single signal supplied as an input to the device  will  result  in  a  series  of  output  signals identical  to  the  input  signal,  although  at  smaller, decreasing amplitudes; the invention prevents the first output signal from being substantially larger than the rest of  the output signals, thus eliminating the need for  protective  circuitry  on  the  output  end  or  the rejection of the first output signal.   In addition to being useful as a recirculating memory device for use in a system where data is generated at a rate faster than it can be accepted by a data processor,  the invention may  be  used  as  a  tap  filter  to  pass  a  selected fundamental   frequency  and   its  harmonics,   and   to attenuate all other frequencies.

Abstract: ABSTRACT OF THE DISCLOSURE        As a car moves along a path through a wash area, it engages a pair of rotating cloth scrubbing wheels.  Each wheel depends from a carriage movable along a horizontal boom pivotally mounted at one end upon a standard located at each side of the wash area.  Each boom is pivoted upon a vertical axis and is swing-able in a horizontal plane between a first position angular to the path and a second position parallel to the path.  Each carriage is biased towards the free end of the boom whereby engagement of the car causes the boom to rotate outwardly while the wheel moves over and engages the front of the car, until the wheel engages the front corner of the car thereby operating a limit switch as a result of car movement which shifts a three-way valve to release the pressure on the carriage cylinder.  The carriage moves up the boom towards the pivoted end thereof as the boom swings into a path generally parallel to the car whereby the wheel operatively engages the side of the car to the rear corner thereof.  Upon actuation of the limit switch and valve, the carriage is moved by its energized cylinder towards the free end of the boom as the wheel cleans the rear of the car to the center thereof and as the boom is swung towards the center to the first position.
