Abstract: Abstract of the disclosure A multistage type amplifier circuit comprises a plurality of FETs cascade-connected to each other through interstage capacitors.  The first amplifier stage of an FET is additionally provided with a feedback circuit coupled between respective gates of the first-stage FET and the next stage FET.  The next amplifier stage of an FET is also provided with a similar feedback circuit coupled between respective drains of the first and next stage FETs successively connected.  Thus, this makes it possible to reduce the required number of de block capacitors to less than one-half, resulting in a small area occupation of capacitors when IC is realized.          Further, the amplifier circuit is configured so that each amplifier stage is not provided with a dc block capacitor in the negative feedback circuit, leading to a significant improvement in frequency characteristics of the amplifier circuit in a low frequency range.

Abstract: Abstract A disposable plastic adaptor connects a medicine vial to a needleless injector.  It includes a hollow, generally cylindrical body member having a top end and a bottom end, with a wall dividing said hollow body into a generally cylindrical top end cavity and bottom end cavity.  The bottom end cavity is adapted to slide over the top end of a medicine vial and the cavity wall includes a plurality of detents which prevent removal of the adaptor from the vial.  The top end cavity is adapted to be twist connected to the end of a needleless injector.  A fluid connector member is mounted within the body member and it comprises a sharp tipped probe extending axially downwardly within the bottom end cavity and an axial projection with a con-cave end face extending axially upwardly within the top end cavity.  An axial bore extends through the fluid con-nector member to flow connect the concave end face and the probe tip.  This probe, preferably in the form of a hollow needle, is adapted to penetrate the top of a medicine vial and the concave end face is adapted to provide a fluid tight seal with a convex end face of a cylindrical medi-cine syringe within the needleless injector.

Abstract: ABSTRACT OF THE DISCLOSURE         This application relates to a guide device or tool to facilitate the replacement of the upper rear seal in an internal combustion engine.  The seal is mounted on a semicircular rigid seal retainer with an outer flange, and the guide device provides for their reinstallation with the flange being received in a curved groove in the block without requiring the removal of the crankshaft from the engine block.  The guide device is bolted to the block using one of the empty bolt holes normally used to hold the lower rear main bearing  in place.  The device has a steel body with an arc shaped edge which extends around a portion of the crankshaft and a number of spaced pins which project from one side of the body adjacent the arc shaped edge.  The spaced pins are located so their inner sides form a segment of a circle which is equal in diameter to the outer flange of the seal retainer and in alignment with the groove in the block.  In order to install the upper seal and retainer, one end is manually slid as far as possible into the groove, with the outer flange bearing against the spaced pins.  The other end of the seal retainer is then tapped with a hammer and the spaced pins act to translate the force around the semicircular retainer to overcome the frictional forces from the crankshaft and groove to allow the seal and retainer to be driven into place.

Abstract: DOCUMENT PROCESSING SYSTEM END EQUIPMENT          ABSTRACT A document processing system including a digital image capture system, character recognition circuitry, document encoding systems, endorsers, audit trail printers and an in-line microfilm record system enable documents to be read, endorsed, encoded, digitally imaged, filmed and sorted in a single continuous pass through the document processor by way of a modular transport system.       The encoding of the continuously moving documents is accomplished by a plurality of fixed dies, electronically controlled hammers, and an ink bearing ribbon interposed between the documents and the fixed dies, the ribbon being momentarily transported at the same velocity as the documents.       Scanning and digitizing of the documents is effected by continuously transporting the documents across the focal plane of a stationary scanner     where the documents are repetitively scanned in a single axis, two scanners being employed to permit scanning and digitization of both sides of a particular document in a single pass through the transport mechanism.  Circuitry is included in the scanner which permits the presence or absence of a document to be detected and allows dynamic adjustment of threshold  levels, thereby accomodating documents which utilize shaded backgrounds.       The system includes apparatus for visually displaying an image which corresponds to a plurality of stored digital values, the apparatus including an image memory and circuitry enabling the display to be partitioned into discrete portions of variable sizes, each portion of which may be utilized either to display a selected portion of the image within the image memory or to display a plurality of alphanumeric characters.  Additionally, circuitry is provided which allows image rotation, mirror imaging and discrete video attribute selection within each portion of the display.     Video data compression apparatus and method are employed for use in minimizing the amount of data necessary to store and recall a black and white video image.  An image initially obtained by vertically scanning a selected document is represented by a series of consecutive vertical scans identifying particular sections or cells of the image as black or white.          A plurality of consecutive scans are then temporarily stored and analyzed horizontally, analysis circuitry being utilized to identify certain consecutive black or white sections of the image, repetitions of previous sections of the image or repetitions of certain selectable patterns within the image.          The coded output of the analysis circuitry is then stored and utilized to reconstruct the image.

Abstract: THERMAL PRINTER                    Abstract of the Disclosure A thermal printer (10) has a thermal transfer medium (28) fed past a thermal printhead (21) at a substan-tially constant velocity by a feed roll (82) engaging the thermal transfer medium just prior to the printhead to maintain a portion of the thermal transfer medium between the printhead and the feed roll relatively stiff.  The feed roll is mounted on a cartridge (30) having the thermal transfer medium supplied therefrom.  A drag brake (70) is disposed in the feed path of the thermal transfer medium prior to the feed roll to cause a substantially constant premetering tension to be applied to the thermal transfer medium irrespective of the coefficient of friction between the drag brake and the thermal transfer medium.  A carrier (14), which supports the printhead and a feed roll driver (90), is driven separately from the feed roll driver so that various ratios between the velocities of the thermal transfer medium and the carrier are obtained to produce various print qualities.  One print quality occurs in a draft mode, which is a relatively high speed, in which there is substantial conservation of the thermal transfer medium.  The peel angle of the thermal transfer medium from a recording medium (12) on which printing occurs is maintained at a relatively low angle to increase the contact time between the thermal transfer medium and the recording medium.

Abstract: The supporting insert for window-panes (15) of multiple insulating glazings for windows, doors or the like has a particular cross-section enabling a better bending, sealing and filling with a desiccating material. Said cross-section comprises on the outer side of the glazing a hollow profile (2) connected to the inner wall (6) and which is narrower than a forked profile (3) on the inner side. These arrangements enable a superposition of a plurality of profiles with a reduced package volume and a faster filling with a desiccant material. Furthermore, the sealing of the window-panes (15) is improved since the profile area (2) which is narrower in bending conditions is not in contact with the window-panes (15).
