Abstract: A method and apparatus for the archival storage of tissue sections which have been cut from a sample block by a microtome blade includes a tape bearing serially-spaced areas of adhesive material, generally the same size as the surface of the tissue sample block. The tape may be delivered from a feed reel by a feed roller mechanism. Between each cut, the tape is advanced to align the adhesive area on the tape with the tissue sample. An application roller presses the adhesive against the sample, the section is cut, and a takeup roller lifts the tape and section away from the blade. The tape may then be wound onto a takeup reel for archival storage. The entire process may be automated, including the operation of a transport mechanism to move the apparatus away from the tissue sample during microscopic imaging.

Abstract: The present invention discloses a method and apparatus for cyclically accelerating the leading end of a slower moving first material web to match the faster speed of a continuous second material web. The apparatus is comprised of a set of upstream metering rolls which feed the first material web at a constant slow speed, a set of downstream applicator rolls having a constant and relatively faster rotational velocity, and an acceleration mechanism which variably and alternately reverses and allows forward movement of a leading end segment of the first material web while allowing for the constant rotational velocities of the upstream and downstream rolls. The first material web is wrapped partially around the set of upstream rolls and the leading end segment thereof is wrapped partially around one of the downstream rolls. The acceleration mechanism is juxtapositioned between the upstream rolls and the downstream rolls in the feed path of the first material web.

Abstract: This invention relates to a process for bonding a vehicle window to a vehicle flange comprising the sequential steps of:a) applying a liquid masking composition to a vehicle flange,b) painting the vehicle, and drying or curing the liquid masking composition sufficiently to form a strippable mask;c) removing the mask from the flange; andd) adhesively bonding the vehicle window to the vehicle flange. Such a masking process advantageously eliminates the need for the use of solvent-based primers normally used to prime a painted vehicle flange, and provides a mask which is more easily applied and removed from the flange than masking means which initially comprise a solid substance.

Abstract: A wafer mounting device transfers a wafer coated with an adhesive and pastes the wafer on a mount plate while maintaining the thickness of the adhesive uniform. A chuck plate is carried by a rotatable transfer arm and holds the adhesive-coated wafer by suction so that the wafer can be moved in a direction of rotation of the arm. The chuck plate is heated by a heater to substantially the same temperature as the wafer. A flexible pressing pad is disposed between the chuck plate and the transfer arm for biasing the chuck plate in a direction away from the arm, and a flexible pressure-adjusting pad is provided for biasing the chuck plate in a direction toward the arm. The pressing pad and the pressure-adjusting pad have hollow sections filled with pressurized fluid, and the pressure of the fluid within each pad is regulated to thereby control the pressing force of the chuck plate so that the wafer is placed softly on the mount plate.

Abstract: A method and apparatus for labeling documents uses an-electronic computer to generate the sequential information required to be placed on each label. This information is then transferred to a printing device which transfers this sequential information onto each individual label. Once the labels are printed in a sequential manner, they are fed into a dispenser which individually or in groups, dispenses the labels in a sequential manner. In order to eliminate any turning of the labels or the documents, the printing device prints the labels in an inverted manner such that they exit the dispenser in an upright legible manner.
