Abstract: The invention is for a system and method of ultrasonically perforating a continuously moving strip of material in a matrix pattern. The system comprises a knurled rotating drum having sharp, perforating projections over which the strip to be perforated is caused to pass. A sonic horn positioned over the strip forces the strip into perforating contact with the drum, rapidly.

Abstract: A device for continuously introducing a gas into a liquid, in connection with a flotation operation, a deinking unit or the like. The liquid issues from an endless annular gap (6) which does not have any internal obstacles whatever such as boundary walls or the like and, after absorbing the gas, flows into a radial diffuser (14) from which the liquid, enriched with gas bubbles, issues into the treatment container of the apparatus. Therefore, for a treatment tank of circular cross-section, a single gasification device which is disposed centrally in the vicinity of the bottom is sufficient. An optional swirl flow may be produced by suitable deflection in the region of the diffuser or in the chamber for the liquid, which is disposed upstream in the annular gap.

Abstract: The invention pertains to an electrophoretic technique for fabricating a progressively graded concentration of dye in a hydrophilic polymeric matrix or gel. A charged dye or dye precursor is caused to migrate under the influence of an electrical potential through the gel matrix. An area is formed in the hydrogel matrix which is progressively graded in optical density as a function of the distance from the point of application to the hydrogel matrix. The insertion of the dye through the hydrogel matrix of a contact lens it may be used to form a contact lens with an optically graded central spot.

The laminate is most useful in fabricating envelopes or packages for electronic components featuring EMI and RFI shielding an electrostatic dissipation. The laminate comprises outer layers of an electrostatic free plastic and a middle layer of conductive fibers in a low density mat of between 0.2 and 0.5 ounces per square yard.

Abstract: A V belt to be used for a dry type transmission. It comprises two endless load carriers and a plurality of blocks in engagement with said load carriers relatively immovable in lengthwise direction of the belt. Said load carrier has elastomers and tensile members embedded in said elastomers. Said block is made of plastics or hard rubber and has slant side surfaces to fit substantially to the groove surface of a pulley on which the V belt is wound and a slot which extends from said slant side surface toward the central part of the block and in which the load carrier is fitted.

This device has a first moving table to move in the axial direction of the mandrel, a second moving table to move on the first moving table in the radial direction of the mandrel, a cutter support carrying a first cutter adjustable in position in the radial direction of the mandrel and/or a second cutter adjustable in the axial direction of the mandrel, and a control unit with a device for detecting the position of each moving table, a device for receiving output signals from the detecting device and comparing the position with position data set beforehand and a driving circuit to move each moving table according to output signals from the comparing device.

Abstract: The invention features a single film construction with two distinctly different surface characteristics for the purpose of an electronic package composite. The non-abrading outside conductive layer integrally bonded to an anti-static interior layer forms a faraday cage package characterized by surface resistivities of less than 10.sup.3 ohms per square on the outside and less than 10.sup.12 ohms per square on the inside.

Abstract: A sofa bed recliner, particularly adapted for use with a futon as a mattress and seat cushion is adapted to move from a seat to a recliner to a bed without need to rearrange the futon. The back frame does not extend backward when moved. The sofa bed recliner is adapted to function as a full double bed with the seat frame and back frame supported and interlocked. An arm is adapted for the interengagement of the seat frame and back frame to facilitate the returning of the sofa bed recliner to its seat position.

Abstract: A modular fabric indoor air conditioner cover set prevents cooling of a room from outside air in a room air conditioner and the loss of heat through the air conditioner. The cover has an opening the periphery of which can grasp the periphery of the indoor portion of an air conditioner. The indoor air conditioner cover is modular in periphery and includes a releasable fold adapted to expand the depth of the cover, thus the cover set with a plastic sheet sealed to the indoor face of the air conditioner provided an effective set for fitting a large variety of different air conditioners and for protecting against unwanted cold.

Abstract: Pin tractors which are used in various printers, typewriters, etc. for use as output devices for electronic computers, especially for personal computers. This pin tractor has a synthetic resin frame around which a belt carrying pins is wound revolvably and a presser member made of synthetic resin supported revolvably by said frame. Blank paper having feed perforations at its both edges is held between said frame and said presser member. Pins of said belt carrying pins are engaged with feed perforations of blank paper for feeding blank paper. Said presser member has pawl parts and said frame has concaves to correspond to said pawl parts. Said pawl parts are fitted in said concaves to keep said presser member opened in the specific degree.

Abstract: An umbrella having substantially the appearance of a conventional umbrella extends to open in the form of a baseball hat with the brim extending. The hat includes baseball team insignia. The closing of the umbrella infolds the brim on a linkage interconnected with the usual umbrella closing mechanism. The closed umbrella with a cover and a bat handle is a set which makes the umbrella have the appearance of a baseball bat.

Abstract: A flooring to be used for vehicles, vessels, etc. The flooring comprises a lowermost rubber layer which makes direct contact with a floor board of a vehicle, a surface layer which constitutes a surface layer portion of the flooring and an intermediate layer interposed between the lowermost layer and the surface layer. The lowermost rubber layer contains a hydrate which discharges water of crystallization at the temperature of 150.degree.-300.degree. C. and accordingly prevents rise of surface temperature by discharging water of crystallization in case of fire in a vehicle and the intermediate layer checks heat conduction from the lowermost layer and thus rise of surface temperature of flooring can be controlled for many hours.

F.

Abstract: The present invention is a method and apparatus for cooling a frozen comestible plasticizer apparatus with a heat exchanger pan over a freezer, protecting the freezer from extraneous matter filling in, while providing a cool circulatable environment to cool the auger and cup of the apparatus to help avoid bacterial growth and minimize the need for cleaning of the apparatus.

Abstract: A contact lens is featured for use by light sensitive wearers. The lens comprises a centrally shaded portion whose shade is optically graded from a relatively darker center to a relatively light or transparent periphery. The diameter of the shade is greater than a fully contracted pupil, as when the eye is exposed to bright sunlight, but less than a fully dilated pupil, as when the eye is exposed to very dim light.

Abstract: The invention features an exercising harness wherein the arms and legs are moved in unison providing a rhythmic exercising routine to be achieved. The harness comprises right and left hand grips, each having an inelastic leg strap attached thereto. An elastic cord is connected between the hand grips and allows a tension to develop between the movement of the limbs on either side with respect to the other side. In a typical routine, first the right arm and leg are raised, while the left arm and leg are held steady. The procedure is reversed, causing an alternating raising and lowering of limbs on each side. This provides a highly rhythmic exercise.
