Abstract: Disclosed is a negative-electrification toner for use in electrophotography. The toner comprises a resin, essentially consisting of a solid silicon varnish, and a colorant so that the resultant latent image can be easily erased or eliminated by the use of a rubber eraser. The novel toner, essentially consisting of a solid silicon varnish, has a low softening point and, as a result, the latent image produced can be easily erased.

Abstract: The electro-optical method described herein provides adjustable voltage dependent optical properties of a solid whereby the characteristics, i.e., the optical response to applied voltage, are separately adjustable for different laser frequencies. The solid has photo-absorbing centers capable of displaying persistent spectral hole burning; the spectral holes are capable of exhibiting electric-field induced filling. The main fields of application for this method are in integrated optics, image processing, and optical data storage.

Abstract: PEG-modified protein molecules characterized by reduced immunogenicity are prepared by covalent modification of the protein with PEG employing an active ester intermediate. Antibodies so modified exhibit decreased binding capacity for Fc cell surface receptors, are non-toxic and retain full antigen binding activity, and are consequently useful in a variety of immunologically-based diagnostic and therapeutic procedures.

Abstract: The invention relates to a method of removing binder materials from a shaped preform (green body) in the preparation procedure for the manufacture of ceramics from particulate materials. The new method comprises exposing the green body to a supercritical fluid to dissolve the binder materials in the supercritical fluid without deforming the shape of the article. In the method, the binder materials can be removed without swelling of the article because the green body is not exposed to a rapid temperature increase and the binder does not volatilize in the body. In addition, the binder material can be removed in a drastically shorter period of time from the entire body.

Abstract: The invention relates to a process and device for the wet treatment of textile material in hank form. The material travels in a circulating passage through an intensive treatment drawframe with subsequent folding-down, further conveying, and finally renewed feeding to the intensive treatment drawframe by a hank winding device. Circulating conveying of the treatment bath through the intensive treatment drawframe occurs while the textile material is passed through the horizontally arranged intensive treatment drawframe essentially at the same speed as the treatment bath. Such material is also under the action of the tensile force of a second hank winding device, which works at essentially the same conveying speed as the hank winding device upstream from the intensive treatment drawframe.

The outboard engine bracing system comprises an outboard extension formed integral with the boat hull and being located above the actual transom of the hull and extending rearwardly beyond the transom. A plurality of brackets are interposed between the transom and the outboard extension, being formed integral with the transom and the outboard extension. The outboard engine bracing system is adapted to have mounted thereon a conventional outboard motor.

Abstract: A holder for dispensing stretch film from a roll comprises a cylindrical body and an arbor rotatably supported on the body. A flexible grip having internal ribs covers the body and the arbor, so that one can, by applying finger pressure to the grip, brake rotation of the arbor and thus control film tension.

Abstract: Several embodiments of drip emitters are disclosed. These embodiments comprise (1) a molded plastic, body with an upwardly opening housing, and (2) a molded plastic plug including an enlarged head, a depending shank, and a helical thread defined about the perimeter of the shank. The body is executed in a relatively soft plastic, while the plug is executed in a harder plastic. The shank of the plug is press-fitted into the housing, and the threads on the shank of the plug cut into the softer plastic of the housing. By advancing or retracting the plug, the length of the helical flow path is altered and the rate of discharge of droplets from the emitter is changed to account for changes in line pressure, accumulation of debris in the emitter, and other operational parameters.

Abstract: The invention relates to a process for refining foodstuffs, and to plant for the implementation of such a process. The basic process is one in which foodstuff is fed into a depressurized environment and refined therein, whereupon the refined end-product, and any waste matter separated during the process, are both drawn off. Plant for the purpose substantially comprises an environment in which a vacuum is created and maintained, such as will house conventional types of machinery which refine the foodstuff, separate any waste matter, and collect the end-product which is then drawn off by a pump. Such a process and plant serve in particular for extracting juice and puree from fruit, vegetable, and market garden produce in general, as well as for reducing meat of all kinds to a paste.
