Abstract: A control system for controlling the velocity of a member in a printing system which utilizes a signal representative of the time variation in intensity produced by the Doppler shift between radiation reflected from the moving member and a reference signal to generate a control signal for correcting the velocity of the moving member. The control signal is applied to a servo mechanism to modify the velocity of the moving member in the appropriate manner.

Abstract: A thermal transfer printer for printing on the face of a plastic card such as a credit card. The apparatus employs a spring loaded support and capstan roller for bending the card to conform to the surface of a printer roller and for forcing thermal elements of a print head into pressure applying contact with a thermal transfer foil sheet and the surface of the card at a printing station. The printing is applied by selectively heating individual thermal elements to transfer thermally transferable printing material from the carrier sheet to the surface of the card. The apparatus also employs a structure for stripping the thermal transfer foil from the surface of the card.

Abstract: Apparatus for monitoring the progress of operations on mechanical components, such as the fitting of railcar wheels to axles, includes a tachometer monitoring motion of the press ram and generating pulses indicative of increments of forward and rearward movement of a press ram, a chart recorder having a pen whose position indicates the pressure applied to the ram, and a stepper motor driving the chart of the recorder, the stepper motor being supplied with stepping pulses proportional to the net forward motion of the ram as calculated from the outputs of the tachometer. Provision is made for predetermined numbers of forward stepping pulses to be supplied to the motor during rearward movement of the ram so as to separate from the chart the traces generated during successive movements of the ram.

Abstract: A piezoelectric bimorph scanner is disclosed which has a flexural beam attached to the free end of a cantilever mounted piezoelectric bimorph crystal. A mirror is bonded to the flexural beam a predetermined distance from the bimorph crystal. An AC voltage of predetermined frequency is applied to the bimorph crystal causing the flexural beam to oscillate with a node at the center of the mirror. The mirror rotates about the node rather than swinging in an arc, enabling the scanner to deflect a collimated light beam over a larger deflection angle than heretofore possible without additional light beam control apparatus. In an alternate embodiment, a laser diode may be mounted on the flexural beam instead of the mirror, further reducing costs and components.

Abstract: A mechanical seismic instrument for recording relative horizontal displacements between the base and foundation of base-isolated buildings or other large structures during earthquakes. A rigid tripod-like arm is connected to the base of the structure; on the other end of the arm is a marking stylus. A record plate is connected to the foundation. When base and foundation move relative to one another, the stylus scribes a record trace on the record plate. Arm and record plate are mounted respectively on mounting plates which are connected and covered by a flexible enclosure. Timing marks on the record trace may be made by striking devices which tap against the shank of the stylus.

Abstract: The present invention provides a process for applying a thermoplastic image forming composition as a series of discrete droplets from a non-contact ink jet printing apparatus to form separate drops on a substrate moving relative to the apparatus, characterized in that the molten composition is thermally stable at the temperature of application and is applied at a temperature in excess of 100.degree. C.The invention can be used to apply the molten composition to a variety of substrates using on-demand or continuous non-contact ink jet application techniques. However, the invention is of especial use in the application of thermoplastic inks to non-porous substrates using an on-demand ink jet printer.

Abstract: A head (13) comprises a closed container (15) carrying internal (139) and external electrodes and a nozzle (18) and is mounted removably on a carriage (14) on which it is held by a permanent magnet (43) in such a way that the head bears with the external electrode against a metal sheet (32). The magnet is of an annular shape and is carried by the carriage. It attracts a metal plate (39) in the bottom of the container, which carries a pin (41) for centering the head on the carriage and is utilized to make connection to the internal electrode (139). A protuberance adjacent the nozzle (18) presses against the metal sheet (32) which in turn presses the paper (11) against a platen (10). The protuberance establishes the jet-to-paper spacing.

Abstract: A single beam direct read during write and write protect system for use in an optical data storage system. The optical data storage system includes a reflective-type optical disk, a laser for producing a beam of radiation to write data onto the optical disk during write operations, and a radiation detector for producing write detect signals representative of radiation detected from the optical disk during the write operations. A slope detector produces verification signals indicative of the accuracy of the write operations as a function of a slope of the peaks of the write detect signals. A digital counter is enabled by the verification signals, and produces a write error signal when a predetermined number of inaccurate write operations are detected.
