Abstract: A method and apparatus for producing histological sections by means of a microtome are suggested. A histological section of predefined thickness is produced with a microtome from a block comprising a tissue sample. A carrier material is applied with an application apparatus onto the block prior to before production of the histological section. To ensure that the histological sections do not roll up, and to enable improved downline processing of the histological sections as compared with a carrier material embodied in the form of an endless strip and that the carrier material is cut out prior to application to a size and/or a shape that corresponds substantially to the cross-sectional area of the block; and that the cut-out carrier material is then applied onto the block. The suggested apparatus is designed to apply the carrier material onto a histological section to be prepared by a microtome.

Immediately before a blade edge reaches the deep part of the notch, cutting movement of the cutter blade is once stopped, reversely moved to a initial piercing position, and thereafter, the cutter blade is moved towards the deep part of the notch from the other open end of the notch while being moved in a reverse direction with respect to the outer periphery of the wafer.

Abstract: A method and apparatus is provided for cutting an elastomeric laminate that may include a layer of reinforcement cords, into a desired length without cutting through the cords. The method includes the step of cutting through the gum portion of the elastomeric composite material at a desired skive angle, and then opening up the skived cut. Next, the cord reinforcement layer is cut without severing the reinforcement cords. An elastomeric composite strip cut to the desired length is produced and has cut ends. One of the cut ends has the gum portion cut at a desired skive angle adjacent an overhang portion of the reinforcement layer. The opposite end of the elastomeric composite segment also has a skived portion to mate with the skived portion of the first cut end, and a gap in the cord ply to mate with the cord overhang of the first end, resulting in a splice. An improved anvil having independently controlled vacuum zones is also provided, as well as improved cutting mechanisms.

Abstract: A method and apparatus for continuously producing pasted positive and negative electrode plates from pasted lead or lead alloy expanded, punched or cast metal mesh strip for use in lead-acid batteries without the use of paper barriers. The heating of cutting devices such as roll-mounted die-cutters to a predetermined temperature range of at least about 150° C., preferably about 160 to 300° C., and more preferably about 180 to 210° C., eliminates sticking of the paste on the pasted metal mesh strip to the cutting devices and obviates the need for the paper barriers.

Abstract: The protective tape applied to the front surface of a semiconductor wafer to protect the wafer during backgrinding must be trimmed so that excess tape, known as tape bur, does not extend beyond the perimeter of the wafer. Tape bur may interfere with backgrinding by causing improper grinding, which may lead to wafer breakage. The tape cutter that trims the protective tape to eliminate tape bur is provided with a sensor which detects whether tape bur has been trimmed from the wafer. If tape bur has not been removed from the wafer, corrective action is taken to prevent the wafer from being backgrinded.

Abstract: An electrically heated knife blade is mounted on a carriage for moving the blade across a strip of elastomeric material. The carriage is propelled by a constant force provided by a pneumatic cylinder in communication with a source of constant air pressure so that the cutting speed is automatically increased at sections of strip material which are relatively thin and the cutting speed is automatically decreased at sections of strip material which are relatively thick. Sensors for determining the position of the relatively thick sections may be connected to the source of electricity for heating the knife blade to increase the voltage while cutting the relatively thick sections and thereby provide for a substantially constant cutting speed across the strip of elastomeric material. A tire tread is bent at the location the knife blade is moved across the tread to provide matching cut ends for splicing on a tire building drum.

Abstract: A cleaning sweeper comprises an adhesive paper roll, a reel support frame, a dual-directional paper cutter, and a handle. The adhesive paper roll is wound on a reel fastened pivotally with the reel support frame. As the adhesive paper roll is moved on the surface of a carpet or floor, the dirt on the surface of the carpet or floor is attached to the adhesive paper roll, which becomes soiled gradually. The soiled paper is cut off with a paper cutter mounted pivotally in the reel support frame. The paper cutter is capable of preventing the adhesive surface of the adhesive paper roll from making contact with the surface of a floor or wall when the cleaning sweeper is not in use temporarily and is laid on the floor or hung on the wall.

Abstract: Thermoplastic elastomers useful in formulating certain pressure-sensitive hot-melt adhesives are normally very tacky and thus are hard to handle. The present invention relates to a method of eliminating problems due to this tackiness by dusting the elastomer pellets with a friable polymer resin having a ring and ball softening point of at least 95.degree. C. Selection of a polymer resin which is normally used in adhesive formulations allows one to overcome tackiness without having detrimental effects on the ultimate adhesive properties of formulations based on the elastomer.

Abstract: A clog prevention device is disclosed for use with a label printing and applying machine. The clog prevention device includes a pair of juxtaposed label guide walls which extend longitudinally up from and at both sides of the printing platen. A label receiving recess is formed in the upper surface of the printing platen between the label guide walls and that recess has a larger width than that of the label strip so that at least both side edges of the label strip may be prevented from contacting the label guide walls of the platen, whereby adhesive at the edges of the label strip does not foul the platen. Label relief grooves are also formed along both sides of the label receiving recess for the same reasons. Openings extend through the platen at the edges of the recess in the upper surface of the platen so that label chips formed when the label strip is pierced or punched during label strip feeding can move away from the label strip.

Abstract: A simple direct acting mechanism moves a circular rotatable disc cutter or two such cutters first to rollably engage a hard surface and then to traverse the surface to part the stock between a side-by-side pair of cords or wires. The cutter or cutters are blunt edged, as well as unheated and so avoid baring the cords or wires while parting the stock without the undesired effect of sharp or hot knives. The cutter or cutters are shiftable along the axis or axes to accommodate deviation of the cords with respect to the travel of the cutter. The foregoing abstract is not to be taken as limiting the invention of this application, and in order to understand the full nature and extent of the technical disclosure of this application, reference must be made to the accompanying drawing and the following detailed description.

Tape feed means are provided and include means for imparting a transverse curl to the tape so that the latter is stiffened lengthwise to prevent bunching or jamming during the hole punching operation.The surfaces of all parts of the device contacted by the adhesive side of the tape are coated with "Teflon" or other suitable material, so that the tape will not adhere thereto as it is moved thereover.

Abstract: An improved apparatus for chopping glass strands is disclosed. The improvement comprises a feed roll for attenuating the strand prior to chopping with a surface having a series of deep grooves cut at desired angles with respect to the sidewalls of the roll. These special grooves reduce binder collection on the surface of the feed roll thereby reducing the tendency of glass strand to wrap around the feed roll during attenuation.
