The carrier strips and associated roller pins can be removed as a unit, thereby simplifying replacement as required by damage or wear.

Abstract: A filter material forming a filter layer consisting substantially exclusively of celluloses and cellulose derivatives. In addition to cellulose acetate fibers, the filter layer contains, in the form of additives, microcrystalline cellulose and microfine cellulose, or else microcrystalline cellulose only. The amount of microcrystalline cellulose can be as high as 70% of the weight of the filter layer and that of microfine cellulose up to 50% of the weight of the filter layer. Cellulose acetate fibers can be excluded if in their place, microcrystalline cellulose having particle sizes less than 10 .mu.m. are used. The manufacturing method provides for cellulose acetate fibers to be first mixed in a wet state with microfine cellulose and microcrystalline cellulose, after which differently prepared celluloses are admixed. The mash formed by mixing is formed into a fleece by means of a known felting method, and the fleece is subsequently dried.

Abstract: An electronic controller having a joystick member, the controller utilizing one or more electrical output circuits characterized by parameters which vary in accordance with the displacement of the joystick member from a "neutral" position in X-axis and Y-axis directions, to control positions on opposite sides of the "neutral" position. The joystick member has a light-reflecting area which traverses a predetermined field of travel as the member is moved between its various positions. A light emitter-sensor circuit including a light source and a light sensor is disposed in the field of travel of the light-reflecting-area of the joystick member. The emitter-sensor circuit generates an electrical signal from a reflected beam of light which is emitted from the light source and is reflected from the reflecting area of the joystick member and onto the light sensor, only when the joystick member is at, or very close to its "neutral" position.

There is a manually-adjustable control including a circuit responsive to pulsed energy, bridging the pick-up coil for bleeding off portions of induced pulses from the coil, thereby to enable a selective control of resultant output from the coil to be had.

Abstract: A container for siftable products such as powders, solid particulates, spices, condiments and the like, comprises a bottle having a threaded neck, a screw cap for the bottle, and a sifter member disposed in the cap. The cap and sifter member are yieldably held together to constitute an assemblage which is applied to the bottle after the latter has been filled. The applying of the cap to the bottle forces the sifter to be transferred to and firmly secured on the bottle neck by cooperable configurations thereon, which provide a more aggressive grip or securement than the hold of the cap on the sifter. In consequence, whenever thereafter the cap is removed from the bottle, the sifter will remain operatively secured to the bottle to carry out its function.

Abstract: A container constituted of injection-molded plastic components, the components having the property of enabling discrete particles thereof to be securely joined to each other under the action of heat and pressure. The injection-molded components form a pair of continuous mating edges adapted to constitute a common continuous joint in the container. The edges initially have configurations enabling them to be mutually abutted, and the edges after being so abutted having been subjected to heat and pressure of a magnitude sufficient to cause them to meet and merge into each other to form the continuous joint.

Abstract: A closure cap construction for a container including a cap body adapted to be mounted on the container and having a discharge orifice, and a sealing cap for selectively closing off the discharge orifice thereof.

The cap body and sealing cap have cooperable engageable sealing surfaces providing a complete peripheral seal therebetween when the sealing cap is disposed in its closing position on the cap body. The arrangement is such that the snap-action hinge is disposed completely exteriorly of the sealing surfaces so as to not impair the integrity of the seal provided thereby.

Abstract: An electronic mouse simulator for a computer having a dedicated mouse port connector receptacle, the simulator having a multi-conductor cable and connector adapted to plug directly into the dedicated mouse port connector receptacle. The simulator includes a touchscreen device and a converter having an EPROM and program firmware therefor. The touchscreen device is preferably positioned in front of or displaced laterally, above, below, or to the side of the screen of the display monitor used with the computer. The converter accepts signals from the touchscreen device and transforms them into a mouse-compatible format or mouse-compatible protocol that can be used to directly communicate through the dedicated mouse port of the computer. No modification of the computer is required; nor is special software needed, since the signals transferred at the mouse port duplicate those which would normally be transferred with a conventional mouse.

In one embodiment, there is enabled an absolute mode of cursor control via the touchscreen device, with the sole electrical connection between the computer and the interface being via the computer's dedicated mouse port connector receptacle.

Abstract: A permanently hydrophilic membrane on an aromatic polysulphone basis and a method for its production. Due to their chemical and thermal resistivity and also because they are unobjectionable with respect to their contacting foodstuffs, membranes on an aromatic polysulphone basis represent a preferred filtration material. But since they are hydrophobic, they would have to be hydrophilated before they are used. Known hydrophilation methods were insufficient to maintain the hydrophilic properties of the membranes, especially after repeated sterilization. The new method aims at making the membranes permanently hydrophilic under sterilization conditions. In an aftertreatment step, the membranes on an aromatic polysulphone basis are conducted, before or after drying, through an impregnating bath of polyvinylpyrrolidone, a copolymer of vinylpyrrolidone and one or more hydrophobic monomers and peroxodisulphate, then heated to 70 to 150.degree. C. and cooled down again.

Abstract: A method to produce nonlinear optical microcomponents is described which makes it possible to employ material combinations not yet used to date. By means of X-ray depth lithography not only waveguide structures, but also microcell structures are produced, into which subsequently material of nonlinear optical properties is placed. By means of X-ray depth lithography and micromolding techniques a mold insert with a waveguide structure is produced as a positive mold, and the waveguide structure is impressed into a polymer base material by means of the mold insert. Then the impressed waveguide structure is filled with optically linear material, and after the filling operation at least one microcell structure is produced, at least in the areas of the optically linear material, into which microcell structure optically nonlinear material is placed. The microcell structure may also be impressed by means of another mold insert.

Abstract: A method to produce nonlinear optical microcomponents is described which employs hitherto not yet used material combinations. Not only waveguide structures are produced by means of X-ray depth lithography, but also microcell structures, into which materials having nonlinear optical properties are introduced. The microstructure is produced as a positive mold part, from which there is subsequently generated, by means of electroforming, a mold insert, a negative of which is made using a polymer material. After the molding operation the microstructure is applied to a substrate, and nonlinear optical material, covered by a cover plate if needed or desired, is introduced into the microcell structure.
