Abstract: One embodiment of the invention is directed to a method of creating and maintaining a calibrated bi-metallic element assembly configuration in a strip chart recorder including a housing having top and bottom portions. The method includes acts of positioning a bi-metallic element assembly on the bottom portion of the housing while the housing is in an open configuration, closing the housing, and attaching the bi-metallic element assembly to the top portion of the housing when the housing is closed. Another embodiment of the invention is directed to a strip chart recorder, including a housing comprising top and bottom portions, the top portion of the housing having a first mating feature, a bi-metallic element assembly having a second mating feature, and a strip chart positioned on the bottom portion of the housing. The first and second mating features are adapted to engage each other upon closing of the housing.

Abstract: An endoscopic system for internal inspection of an object includes an endoscope extending along a longitudinal axis between a distal end to be inserted into the object and a proximal end and an illumination assembly attached to the proximal end of the endoscope. The illumination assembly includes a solid-state light source. The endoscopic system also includes an optical system positioned distally from the solid-state light source to receive and convey light to the distal end.

Abstract: A system for printing data on a prescribed record form, which is repetitively inserted into and removed from a printing device, that includes a printing unit for printing the print data on the prescribed record form, a feed control unit for feeding the record form automatically in a prescribed printing position direction, a detection unit for detecting angular misalignment of the record form from a prescribed printing position each time the record form is inserted into the printing device, a print data computation processing unit for computing a corrected printing position from the position data of the detected angular misalignment, and a print control unit for controlling the printing unit to print the print data according to the corrected printing position.

Abstract: In a vehicle operation recorder for motor vehicles, the recording devices are permanently undetachably connected to the display devices, the diagram chart carrier is arranged in a separate compartment of the casing which is offset laterally or rearwardly in relation to the main instrument dial, and the marker pens are arranged above the diagram chart in likewise laterally offset relation to the main instrument dial and are connected to the recording devices by a rigid bridge member.

Abstract: An X-Y plotter disclosed is of the type which moves a recording paper with no perforation by drive rollers and pinch rollers. A plurality of sharp projections are arranged on the outer surface of each of the drive rollers such as to enable an exact feeding of the paper without any slippage. These projections are formed by cutting in the outer surface of each drive roller with V-grooves parallel and orthogonal to the shaft of the drive rollers.

Abstract: Improved plotting and printing apparatus has a writing surface for supporting a printing medium and which has an opening for exposing the underside of the medium. A transparent plate is mounted to the supporting surface so as to permit placement onto that surface of a printing medium such as a plural leaf form set whose area is larger than that of the plate so that one portion of the medium extends across the opening under the plate and can be printed on by a printer positioned under the surface opposite the opening, while another portion of the medium lies on the surface beyond the plate so that it can be written on from above the surface.

Abstract: A device for recording the flow rate through a flow meter over a period of time is provided for use in conjunction with a flow meter having a rotatable member, the rotational position of which is indicative of the fluid flow rate through the flow meter. The recording device comprises a housing in which a recording medium is mounted and rotatably driven at a predetermined. rate. An elongated scribe arm is pivotally secured at one end to the housing and, at its other end, has a writing instrument which engages the writing medium and produces a visible mark thereon. Similarly, an elongated actuating arm has an axle which is pivotally mounted to the housing and this axle in turn is connected to the flow meter rotatable member. The actuating arm and scribe arm are in turn connected together by a connecting arm which is pivotally connected to the actuating arm at one end and pivotally connected to the scribe arm at its other end.

Abstract: In the preferred and illustrated embodiment of a recording device, a fluid volume driven chart bracket is disclosed. The bracket is rotationally responsive to fluid flow through a pipeline or the like. A recording chart is rotated by the fluid flowing through the pipeline via a volume driven gear train and the chart bracket. An automatic chart changer clock is mounted to the bracket to periodically change the recording chart. The variables recorded by the device are weighted proportionally to the volume of fluid flowing through the pipeline.

Abstract: Recording apparatus includes a planar support for supporting a flat recording medium such as one or more circular graph sheets. At least one recording instrument, e.g., a wire pen, is arranged to be movable relative to the support to provide a recording on the recording medium when the instrument is moved into contact with the medium and the medium is driven at a given rate. A lid is provided for covering the recording medium, the lid being arranged for pivotal movement about a hinge axis between open and closed positions relative to the support. The lid also serves to move the recording instrument into contact with the recording medium when it is in the closed position, and to lift the recording instrument out of contact from the recording medium when in the open position. A movable, guide part contacts the recording instrument to lift the instrument out of contact from the recording medium when the lid is moved to the open position.

Abstract: The sheet clamp apparatus is for clamping a sheet of original paper, recording paper, photosensitive paper, master plate, or the like on a drum usually provided in facsimile apparatus, copying apparatus, or the like. The apparatus comprises a single plate-shaped clamp member positioned along a generating line of the drum and at a part of the peripheral surface of the drum. The single clamp member presses firmly both the front edge and the rear edge of a sheet against the drum. The front edge of the sheet is clamped with the drum being stopped at a predetermined position, and the rear edge of the sheet is clamped after the drum has made about one revolution from the predetermined position of the front edge where the sheet is clamped.

Abstract: A recorder segment electrode assembly is pivotably mounted to an access cover of an electrographic recorder in such a manner that the segment electrode assembly is in a first protected and inoperative position when the cover is open. When the cover is closed, the segment electrode assembly is caused to pivot to a second extended and operative position in contact with recording paper.

Abstract: Electrocardiographic apparatus wherein said apparatus is contained within a wholly insulated enclosure and the recording assembly including writing pens is provided with means for placing an insulating barrier in a position to protect the pens when replenishing the recording paper.

Abstract: A chart recording instrument having electromechanical servos which move a pen or stylus in the X-direction along a paper chart, and move the chart with respect to the pen in the Y-direction. A novel mechanism provides for ease in loading and unloading charts, and for accurate relocation of the chart, whereby a chart can be removed from the machine and then replaced accurately without disturbing any of the gain or zero control settings. Thus a curve can be recorded, the chart removed, and then put back to record another curve in the same family. These functions are controlled by a three-position lever which lifts and lowers the pen, raises and lowers pinch rollers in the Y-axis chart drive system, controls a pair of chart positioning stops, and switches appropriate positioning voltages to the servos.
