Abstract: A modular-design recorder consists of a "print engine," a drive assembly for moving a print medium, e.g., paper, through the print engine, and a chassis for supporting the engine and the assembly. The chassis includes two identical sets of mounting studs, one on either side, for the mounting of the drive assembly. The drive assembly consists of a motor, a gear train through which the motor rotates the roller, and a bracket for mounting the motor on the either side of the chassis in a number of different angular orientations. The motor attaches to one end of the bracket, such that it mounts facing either toward or away from the chassis. The opposite end of the bracket mates with the mounting studs on the selected side of the chassis. The print engine consists of a print head, a roller for advancing the paper past the print head and a deflector.

Abstract: An antiglare panel is formed of a series of identical inter-locked strips. Each of the strips is formed of a series of "W" shapes having two connected short legs formed at right angles to each other and two long legs extending at right angles from a respective short leg to define the "W" shape. The long legs of adjacent "W's" are formed at right angles to define a projecting right angle. The projecting right angles of one strip are positioned within the recessed right angles of an adjacent strip so that the interior surface of the short legs overlie a portion of the exterior surface of the long legs to provide contacting surfaces. Such contacting surfaces may be secured together.In a preferred embodiment, the strips are formed of tinned steel strip, and the assembled strips are heated after assembly to a temperature above the melting point of the tin coating to provide a metal bond at all contacting surfaces.

Abstract: A ribbon cartridge for use in a high speed band printer includes a body having a ribbon storage compartment where the ribbon is contained in a multiplicity of serpentine folds. The body has a ribbon inlet and an outlet end and guide arms extend from the inlet and outlet ends to guide the endless ribbon into and out of the cartridge and to define an exposed loop of the ribbon between the outermost end of the guide arms. The outlet end and outlet arm of the cartridge is formed to define a ribbon inverting device which serves to invert the ribbon 180.degree. each time the ribbon passes through the device.

Abstract: A ribbon cartridge is detachably connectable to a high speed band printer. The cartridge includes a body which has a ribbon storage compartment where the ribbon is contained in a multiplicity of serpentine folds. The body has a ribbon inlet end and outlet end, and guide arms extend from the inlet and outlet ends to guide the endless ribbon to define an exposed loop of the ribbon between the outermost ends of the guide arms. The exposed loop is positioned in the printer adjacent the paper to enable the ribbon to be impacted by appropriate printing characters. The body includes an opening which receives the ribbon drive rollers of the printer in a manner which engages the ribbon and advances it progressively. Adjacent the inlet end of the body, and in the region of the opening, the device includes a ribbon control assembly which cooperates with the rollers to assure proper threading of the ribbon between the rollers as well as to minimize any tendency for the ribbon to jam in the machine or in the cartridge.

Abstract: A cartridge which contains an inked ribbon for use in a high speed printer such as a wire matrix printer and typically driven by a capstan of the printer. The ribbon is arranged in the form of a mobius loop and the cartridge is constructed in a minimal number of components including a cartridge cover and cartridge base together forming a compartment for most of the loop, and a slotted pinch roller. The cover includes an integral pinch roller support post and part of the means for controlling the twist in the mobius loop. The base includes an integral ribbon peeler associated with the pinch roller and the other part of the control means for the loop twist. The cover and base are provided with ribbon guide means to support the ribbon only along a section thereof between the egress and ingress of the loop to the compartment, leaving a relatively long, linear portion of the ribbon unsupported by the cartridge, thus enabling use of the cartridge either in a stationary position or piggybacked to the printing head.

Abstract: A compression stressed liner for refrigeration equipment and a method of stressing the same is disclosed. The effective life span of refrigeration equipment liners can be significantly increased by compression stressing. Stressing liners in compression before or during assembly of refrigeration equipment is accomplished by bending the liners, molding the liners to form a shallow arc in one direction of its structure or shrinking the liners and then securely attaching the same. Compression stressed liners counteract localized tensile stresses that normally develop because of shrinking of the liners during use at temperatures substantially below assembly temperatures. Compression stressing of liners also reduces the size of or eliminates foramina on the exposed surfaces of the liners, normally increased in size by the tensile stresses, thus decreasing chemical penetration and attack of liners.
