Abstract: The switch according to the invention has a contact pair whose contact ends touch one another in a sprung manner in the switched-on position. The contacts of a contact pair are jointly carried over into their respective switching positions, via cam projections, so that the switching paths of each contact end can be designed to be relatively small, without prejudice to maintenance of the required safety distances in the switched-off position. Between the contact ends, a spacer can be inserted which allows further circuits to be connected. <IMAGE>

Abstract: An illumination aperture (6) for receiving radio waves in a radio wave introducing member (2) is blocked by a covering member (17), and thus dust is prevented from coming into the illumination aperture externally by the covering member. The covering member is so thick as will coincide with the trough in a transmission loss curve of radio wave of the synthetic resin used as a forming material for the covering member. Accordingly, a mechanical strength of the covering member is high. Then, an expected attentuation of the radio wave going toward the illumination aperture through the covering member is very little.

Abstract: A method is disclosed for computer implementation of products wherein a designer examines the products desired by an institution planner and identifies functions ("components") collectively common thereto. The designer proceeds to define component processes collectively common to such component and categorizes code for this purpose in groupings selectable (executable) by the planner upon system installation and subsequently changeable as desired. The component process selections of the planner are recorded and the system is thereby defined in its aspect which is accessible to the planner. The designer works from such definitions of all components and component processes obtained from discussion with system planners prior to installations to define component subprocesses collectively common to the component processes and identifies combinations of component subprocesses in various sequences to realize component processes. The code of each component subprocess is stored individually in "modules" for access by a computer to realize such combinations and reuse of such modules in this activity is effective to provide for uniformity in the practice of subcomponent processes from product to product. The designer code for the component subprocess is inaccessible to the planner from a selection viewpoint and is viewed thusly as planner non-executable.

Abstract: In the case of an automatic test device for the correct position of labels of technical articles, preferably magnetic tape cassettes, a light beam coming from a narrow gap (9), which is impinged with infrared light via a light guide (10), is directed at at least two points on the label edges (12) and the remitted light is passed via a parallel gap (11) via the light guide to a detector device and to an assessment logic, which has the article passed or rejected. In the case of a different design, a transmitted-light barrier activates four reflected-light barriers, which are arranged in the region of a narrow side of the label and check the latter for correct position. A set of further reflected-light barriers, in mirror-image arrangement, are located on the other side of the cassette. On reaching a second transmitted-light barrier, the region of the other narrow side of the label is scanned. <IMAGE>

Abstract: The present invention provides a cleavable immunoconjugate whose linker contains a labile bond that is cleavable under a variety of mild conditions, including weakly acidic. Since the agent may be bonded directly to the linker, cleavage can result in release of native agent. The invention also provides methods for producing a cleavable immunoconjugate. Preferred agents include drugs, toxins, biological response modifiers, radiodiagnostic compounds, radiotherapeutic compounds, and derivatives thereof. The antibody employed in the invention may be an intact molecule, a fragment thereof, or a functional equivalent thereof. In a preferred embodiment, the specific antibody is a monoclonal antibody directed towards a tumor-associated antigen in man. The invention further provides a method for delivering to the cytoplasm of a target cell an agent free of its antibody carrier. A diagnostically or therapeutically effective dose of a cleavable immunoconjugate is administered to a mammal such as man. 
     Another aspect of the invention provides a method for isolating a compound containing an available nucleophilic group, such as a free sulfhydryl, amino, or hydroxyl group. The compound binds covalently to a solid phase which has been derivatized with the linker described above and is released in native form by a variety of mild conditions. 
     An additional aspect of the invention provides a method for introducing into a compound a free sulfhydryl, amine, or hydroxyl group by use of a reagent structurally related to the linker described above. Preferred uses of the method are to add a free amino or a free sulfhydryl group to a protein, such as an antibody. This method has broad   application in the field of compound modification, especially protein modification.

Abstract: An apparatus that generates a cyclic waveform of op­tional multiples of clock frequency in a digital signal processing. The apparatus accumulates a data string having a predetermined average value and a constant with an ac­cumulating circuit which overflows when the data exceeds a dynamic range, thereby to provide cyclic waveform data proportional to the sum of the average value and the con­stant. Accumulation of the sum of the average value and the constant provides a cyclic waveform of optional multiples of the clock frequency by changing the average value of the data string even if the constant is integer.

Abstract: The invention relates to a method for representing accentuated letters on the monitor of teletyping and text stations. It is the object to achieve this representation in an operator-friendly manner with as few key actuations as possible, in which connection the representation should be effected in one process on the monitor. The object is achieved by the fact that two existing control keys, which are only effective in conjunction with another key which is operated at the same time, are used for forming a code for the accentuated letters so that these letters provided with the accent can be represented in one process on the monitor. Whether an accent is to be represented depends on whether the associated letter is a vowel or a consonant. The method can be applied in teletype and text stations and in personal computers.

Abstract: The elimination of impurities, for example monomeric substances of low molecular weight, solvents or the like, from polymer plastics is performed by mixing in extraction gas in a first extruder (1), in a super-critical state. The mixture is transferred into a second extruder (18), where, in a first separating zone (26), it is freed by a counterflow process of the major portion of the extraction gas carrying the impurities, through a draw-off orifice (25). In a downstream vacuum zone (31), a residual separation takes place. The high pressure in the first extruder is maintained by a counter- pressure valve (17) in the connecting line (16) between first extruder and second extruder. By the separation of contaminated extraction gas and plastic melt in a closed space, namely the second extruder (18), an orderly discharge of extraction gas on the one hand and plastic melt on the other hand is possible.
