Abstract: ABSTRACT         A fastener clip and joint structure incorporating same especially adapted for use with thin or narrow furni-ture parts, panels, or the like to reduce splitting or fracture of the parts when joined and/or stressed. The clip is formed from a one-piece metal plate, preferably of annealed spring steel for flexibility, having a raised, central, slotted portion and a pair of end flanges for securing the clip to one joint member.  One end flange extends outwardly away from the central portion while the other extends under the central portion.  A stud on an opposite joint member is slid along an inclined slot in the central portion to draw the joint members together.  In one embodiment, an enlarged opening in the slot allows access through the slot to the end flange beneath the slot for fastening the flange to the joint member.

Abstract: ABSTRACT OF THE DISCLOSURE         An amorphous iron-based alloy which comprises not more than 25 atom% of Si and 2.5 to 25 atom% of B          (providing that the sum of Si and B falls in the range of 15 to 35 atom%), 1.5 to 20 atom% of Cr, 0.2 to 10 atom% of either or both of P and C, and the balance to make up 100 atom% substantially of Fe excels in fatigue property. An amorphous iron-based alloy which contains not more than 30 atom% of at least one element selected from the group consisting of Co, Ni, Ta, Nb, Mo, W, V, Mn, Ti, A?, Cu and Zr in addition to the components making up the aforementioned alloy excels in amorphous texture of forming ability and fatigue property.  Since these alloys are also excellent in tensile strength at fracture, thermal resistance, corrosionproofness, and electromagnetic property, they prove highly useful as electromagnetic materials and as reinforcements in various industrial materials.

Abstract: ABSTRACT          This invention relates to infrared transparency films and films for thermal imaging processes, and in particular, to a coating material for such films.          Infrared imaging involves the use of a focused infrared lamp to heat an infrared absorbing image, i.e., the "original", which is in contact with a substrate, e.g. a transparency film, having thermally sensitive imaging chemicals.  Upon absorbing the focused infrared light, the infrared absorbing image heats the thermally sensitive imaging chemicals on the substrate, causing a chemical reaction, resulting in a copy of the original image on the substrate.          When projection transparencies are prepared from originals which are plain paper copies prepared from electrophotographic imaging processes, localized heating of the original results in partial remelting of the toner powder thereon, causing the original to adhere to the transparency.  When the original is separated from the transparency, toner powder from the original is transferred to the transparency film, resulting in partial destruction of the original and irregular black spots on the transparency.         This invention provides a coating for infrared transparency films and thermal imaging films comprising a copolymer formed from (a) at least one fluorocarbon monomer and (b) at least one monomer which imparts hardness to the copolymer.  The coating serves to prevent the transfer of toner powder from an original to the transparency film.

Abstract: MICROTOME HAVING A FORWARD-FEED CONTROL SYSTEM FOR THE       SPECIMEN ARM AND/OR THE KNIFE                 ABSTRACT OF THE DISCLOSURE     A microtome, especially an ultramicrotome, is disclosed in which a forward-feed system for the specimen arm and/or knife of the microtome comprises a stepping motor which is controlled by a pulse generator and which shifts the specimen arm, and the knife, relative to each other by an appropriate amount of forward feed in accordance with a forward-feed value which is set at one of a plurality of preselector switches.  In order to facilitate quick switching over from one forward-feed amplitude to another, permitting the selection of forward-feed amplitudes which differ by an order of magnitude, for example, if semi-thin sections are to be produced during a run of ultra-thin sections, the forward-feed amplitudes set by the preselector switches can be switched, according to choice, to the pulse generator for the stepping motor by means of a changeover switch.  This arrangement enables the operator to alter the forward-feed amplitude by one manual action without disturbing the ongoing operation.

Abstract: RCA 78,822 ABSTRACT           A protection circuit (44,45) is coupled between a low voltage signal processing semiconductor device (40) subject to damage by high voltage transients, and a signal output terminal (21) at which high voltage transients can appear.  The protection circuit comprises a first transistor (44) arranged as an emitter follower for normally conducting signals from the semiconductor device (40) to the output terminal (21), and a second transistor (45) of opposite conductivity type.  The base and emitter electrodes of the first transistor (44) are directly connected to the base and emitter electrodes of the second transistor (45), respectively, such that the second transistor (45) is normally non-conductive.  Transient currents associated with negative high voltage transients at the output terminal (21) are diverted to a point of operating potential (+Vcc) via the first transistor (44). The second transistor (45) is rendered conductive in response to positive high voltage transients at -the output terminal (21) for diverting associated transient currents to a point of second operating potential (ground).

Abstract: ABSTRACT OF THE DISCLOSURE           An installation for the production of chemical substances is sub-divided into control regions which are controlled in a decentralized manner and in which a closed divisional function is carried out independently in each case.  The working condition of a control region is determined by operating types which may be initially given and by a limited number of discrete operating values.  The process parameters determining the control region condition are allocated to each operating value in one formulation. These parameters are adjusted by means of suitable devices. In the event of deviations of a parameter, the other formulation parameters are not adapted, but the procedure is interrupted if the permissible parameter limits are exceeded.  Increases in the operating values are only permissible from a quasi-stationary working condition which is characterized by a normal signal formed from the process measurement values.  In several control regions, the necessary flexibility is secured by a flow decoupling by means of buffers.  Similar control regions are combined into groups, and different groups are combined into main groups. Groups and main groups are controlled together and are decoupled from one another by strategic buffers.            Le A 21 764-US/CA

Abstract: ABSTRACT OF THE DISCLOSURE         A weighing system is disclosed which operates in conjunction with a scale that has a trigger mechanism for terminating the flow of material into the scale's bucket.  This system automatically periodically revises a tare signal stored in a latch circuit for combination with a weight signal to produce a net weight signal.  The tare signal provides a measure of the residue stuck in the scale bucket.  In an additional embodiment of the invention, a programmable controller is used as the means for periodically resetting the tare signal and is used to evaluate the final weight data produced by the scale in order to form a computer setpoint signal to adjust the triggering of the flow termination so that the final weights will most closely approximate the desired predetermined weight.
