Inventor: PAUER JERICHO P
IPC: A47F3/00
Filed: 1992-02-03
Abstract: A hutch (10) of a preferred form is shown including a top (14) and bottom (16) initially held in a spaced relation by their sandwiching between collars (35) and nuts (36, 37) fixed on and threaded on, respectively, the ends of vertical rods (32) extending through apertures (34) formed in the top (14) and bottom (16).  The upper and lower edges of first and second glass ends (18) and first and second, glass, front sides (22) are slideably captured in groves (28, 30) formed in the top (14) and the bottom (16).  Bolts (38) threaded in the top (14) abut with the upper edges of the ends (18) and sides (22) to compressively capture the ends (18) and sides (22) between the grooves (28, 30) and to tension the vertical rods (32).  A back (20) including a mirrored face (26) is secured to the top (14) and bottom (16) to provide diagonal support of the frame.  Glass shelves (40) are supported by independent shelf supports (42) adjustably and slideably positioned on the vertical tension rods (32).  The tension rods (32) and shelf supports (42) include a highly reflective chrome plating to create the visual effect of the top (14) floating in a spaced, parallel relation above the bottom (16).

Abstract: ABSTRACT OF THE DISCLOSURE           An ergonometric chestpiece (12) for a stethoscope (10) adapted to receive auscultatory sounds from a body and adapted to be coupled to an earpiece (18 and 20) for a user.  The chestpiece (12) is adapted to be grasped by a thumb and at least one finger of the user.  The chestpiece (12) has a bottom surface (36) which is generally planar and is adapted to be placed near the body for receiving the auscultatory sounds.  The chestpiece (12) has an upper portion opposite the bottom surface (36).  The upper portion has a raised center portion (26) defining left and right gripping surfaces (28 and 30) which form recesses defined by the left and right gripping surfaces (28 and 30) and by a surface generally parallel to but opposite the bottom surface (36).  The left and right gripping surfaces (28 and 30) are adapted to receive the thumb and the finger of the user.  Left and right gripping surfaces (28 and 30) along with the surface generally parallel to but opposite the bottom surface (36) form a physical stop for the thumb and the finger from contacting to body when the thumb and finger grasp the raised center of the upper portion.  The gripping surfaces (28 and 30) may be defined by left and right walls disposed generally normal to the bottom surface (36).  The left and right walls may be concave. The ergonometric chestpiece (12) may be generally circular and the left and right walls may be cylindrically concave around axes generally orthogonal to the bottom surface (36).  The top surface of the raised center portion (26) may be sloped with respect to the bottom surface (36), the top surface being closer to the bottom surface (36) at the front of the chestpiece (12) than at the rear of the chestpiece (12).

Title: Printer ribbon drive system
Inventor: BARRUS GORDON B
IPC: B41J33/52
Filed: 1992-09-23
Abstract: This disclosure sets forth a dot matrix printer having an improved ribbon drive.  The ribbon drive is provided by two respective stepper motors.  When one stepper motor is in a take-up mode, the second is in a feed mode.  The process is reversed proximate the end of the tape as it is unwound.  A re-generative mode for the feed motor is provided and a resistance bank varies amounts of drag on the ribbon as it is fed from the feed motor spool.  Both motors when in the take-up mode are driven by full H bridge drivers and amplifiers controlled by a micro controller through an address and decode input and output latch.  In order to provide for a uniform velocity of the print ribbon the angular velocity of the take up motor is controlled by counting the zero crossings of the feed motor, and then loading it into the micro controller to compare it with a look-up table for purposes of providing a proper speed to the take-up motor and the proper peak drag through the resistance bank to the feed motor.  All functions are controlled by the micro controller and firmware logic provided thereto.

Title: Filter units
Inventor: HUGGETT DAVID J
IPC: B01D36/00
Filed: 1992-09-25
Abstract: ABSTRACT OF THE DISCLOSURE     A filter unit  comprises  a  housing  containing  a  filter element.  The housing includes an inlet for fluid and an inlet passage which passes fluid to the filter element.     An outlet passage conveys filtered fluid from the element to an outlet to the housing.  The inlet passage includes a valve  which  can  close  the  inlet  passage.   When  this happens, a by-pass valve opens and connects the inlet to the   housing   direct   to   the   housing   outlet.    An anti-backflow valve is provided in the outlet passage to prevent fluid passing back down the outlet passage to the filter element.  The filter element can then be changed.          A re-pressurization valve is provided to pass fluid to the element while the inlet passage is still closed and a vent port   vents   air   from   the   element  during   this re-pressurization.    Once  re-pressurization  is  complete, the vent port and the re-pressurization valve are closed and the inlet valve opened so that filtration recommences.

IPC: H01H1/58
Filed: 1993-04-08
Abstract: A screw retainer is fabricated from a thin sheet of spring steel and is comprised of three sections: a screw support section, a leg support section and a leg section. The screw support section contains a through-hole for receiving a support screw. The leg support section is bounded by the screw-support section and the leg section. The leg section is angulated with respect to the leg support section and has a degree of spring action that allows it to be compressed so as to allow it and the leg support section to be inserted between the respective lower portions of integrally-formed upstanding support arms of a support base. Once the screw retainer is completely inserted between the respective lower portions of the integrally-formed upstanding support arms, the leg section springs back to its normal position thereby preventing the screw retainer from becoming dislodged from its position.

Title: Process and apparatus for controlling lateral deviations in a moving web
Inventor: BRAU JURGEN
IPC: D06H3/04
Filed: 1993-10-19
Abstract: ABSTRACT      The invention relates to a process and apparatus for controlling lateral deviations of a moving web from its correct position.  The process involves determining the actual position of the web and creating a positioning signal for a mechanism that controls the web's position, depending on the deviation of the actual position from the correct position. This is achieved with the help of an image/signal converter scanning at least a lengthwise portion of the web as it passes by the converter.  A recognizable feature present in or on the web serves as a guidance criterion contained in the lengthwise portion is scanned at regular intervals and for each scan the image signals are stored and the actual position of the web is determined by analysis of the signals.  For each scan the entire content of the image of the scanning field of the web covered by the image/signal converter is translated into image signals of only one single row of image dots extending crosswise to the web's direction of motion over the entire width of the scanning field.  These image signals are stored. Before the control process begins, the image signals representing the guidance criterion are stored by themselves as fixed reference signals.  During the control process the row of image dots with the image signals stored from each scan are regularly stepped against the row of image dots with the stored reference signals and for each stepping increment a similarity function is calculated from the signals of the two rows of image dots stepped against each other, the value of which function for each stepping increment is a measure for the degree of congruence of the two series of signals.  The respective actual position of the guidance criterion is determined from the stepping with the function value that provides the best congruence.
