Abstract: The present invention is directed to a method of maintaining a cover on the razor head of a wet shave razor. Such a cover is used to prevent damage to the cutting edge of the razor and to prevent accidental contact with the cutting edge when the razor is not in use. The present invention is also directed to a razor unit having a cover which is semi-permanently affixed to the razor head via a protective seal. The cover is affixed to the razor head during manufacture in a position such that it covers the cutting edges of the blades. Preferably, the cover is affixed through the use of an adhesive strip or strips which are attached to the cover and the razor head. The user must manually remove or break the adhesive strip in order to remove the cover to expose the cutting edge and begin shaving.

Abstract: A method of cutting, slicing or perforating photographic imaging elements using certain cutting tools is disclosed. The cutting tool material includes zirconia and yttria at a molar ratio of yttria to zirconia from about 0.5:99.5 to about 5:95. The cutting tool is essentially a tetragonal crystal phase grain for the interior in a surface of cubic crystal phase grain or monoclinic crystal phase grain. This provides a hard, tough outer surface with a tough core. The cutting tool material can also be a composite of zirconia-alumina with or without surface modification.

Abstract: A wafer to be diced to form chips is placed on the sticky side of a thin elastic film in the form of a Swiss Cross which is secured to the side members of a compressed but expandable square frame, the frame being placed in a scribing and dicing machine in its released state so that the frame and thus the film can expand during the dicing operation, further expansion being accomplished after dicing of the wafer by heating the film while in an expansion fixture to insure removal of the chips from the film without damaging adjacent chips. The sticky material on the film may be rendered less sticky after formation of the chips by exposure to ultraviolet energy or the like.

The dispenser includes a base for supporting a roll of the plastic film wrap, a puller for engaging an end of the plastic film wrap and removing a selected length of the plastic film wrap, and a cutter movable across the width of the plastic film wrap for cutting said selected length of the plastic film wrap from the roll.

Abstract: Point needles in a collecting cylinder are driven in a two stage extension process to initially needle or pierce the leading edge of a product web being cut. Once the cut has been made, the needle tips are moved further radially outwardly from the cylinder to secure the cut edge. As the signatures are transferred to a folding cylinder, the needle points are retracted along a single stage retraction curve which is different from the path traveled during the two stage extension process.

Abstract: A roll type stock feed apparatus having one feed roll rotatably mounted on a stationary frame structure, and a second feed roll mounted on a movable roll carrier and yieldably urged into a stock engaging condition. An electro-responsive servomotor is drivingly connected to at least one of the feed rolls for driving the feed rolls through a preselected feed cycle. An elongated ram position sensor is slidably mounted on the stationary frame structure for lengthwise reciprocation along an upright path and is yieldably urged upwardly relative to the frame structure to a preset raised position on the frame structure. A cam on the ram position sensor member engages a cam follower on the movable roll carrier and is operative in response to movement of the sensor member downwardly from the preset raised position to move the roll carrier and the second stock feed roll to a stock release condition.

Abstract: A razor blade assembly has a body member containing blade means which may be resiliently mounted and biased outwardly from the body member. A wrap-around clip is provided at both sides of the body member, the clip having its ends terminating at the bottom surface of the body member. Means are provided for inhibiting movement of the clip ends relative to the bottom surface upon impact loading of the razor blade assembly.

Abstract: An apparatus and method is provided for simultaneously perforating and cutting a lithe sheet material having multiple layers containing at least an upper and lower layer, comprising a knife die having a cutting edge, wherein the cutting edge is contained in the same plane, and an anvil die located opposite the knife die, wherein the surface of the anvil die contains a pattern of cavities which corresponds to the locations where primarily only the upper layer of the material is cut completely through and protrusions of the anvil primarily correspond to the locations where the entire thickness of the material is cut along the same line as the cut through the upper layer.

Abstract: A cryostatic microtome with an automatic approach of the preparation automatically stops the feed movement between the microtome knife and a frozen preparation towards each other upon a mechanical contact between the knife and the preparation. An electrical voltage of a few volts is applied between the microtome knife and the preparation. A small current which appears, due to the intrinsic conductivity of the preparation, upon mechanical contact between the preparation and the microtome knife, and a smaller voltage drop at the preparation resulting therefrom, is current amplified by means of a preamplifier connected as an impedance converter and subsequently measured. The feed movement between the preparation and the microtome knife is automatically stopped when the voltage at the amplifier output falls below a predefined threshold voltage.

Abstract: An improved saw assembly (30) includes a rotatable arbor (74) on which two or more saw blades (75) are mounted. The driving interface (96, 98) between the saw blades and the arbor permits the axis of rotation of the saw blades to be collinear with the arbor axis (90) or skewed a few degrees (94) in either direction. A saw blade positioning assembly (72) includes pairs of guide arms (84) which engage the sides (88) of the saw blades to position each saw blade at the proper location along the arbor and at the proper skew angle. The guide arms are moved in unison so that the axial position and the skew angle of each of the saw blades can be changed in unison before and during sawing operations.

Abstract: A method for cutting the leader of the web in a paper or board machine in the dryer section of the machine by a jet of pressurized water. The web is placed against the drying wire when it is being cut, and the jet is directed at the web from the free side of the web. The water jet pressure used is from about 40 bar to about 400 bar, preferably from about 100 bar to about 350 bar, which is produced by an ordinary pressure washer.
