Abstract: Known pivoting levers have at their free end a defined actuation edge which can only be extended by additional parts. A novel lever (10) has at its free end a guide member (16) which serves as actuation edge and, in its interior, a recess (18) which serves to receive and guide an actuation arm (20), with which its actuation range can be extended. The pivotable lever is provided in particular for use in switch mechanisms for electrical switchgear which can be combined to form multi-pole switchgear. <IMAGE>

IPC: C01G1/00
Filed: 1989-05-01
Abstract: A method for producing a superconductive oxidic layer containing at least one bismuth-cupric compound on a substrate produces layers containing an effective proportion of a phase having a critical temperature above 100 K. In the method, a homogeneous solution of organometallic compounds is deposited on the substrate and the organometallic compounds are then thermally decomposed. The process is repeated, if necessary, until the predetermined layer thickness has been reached. The layer is then heated to a temperature between 700 and 950 DEG C in order to obtain the desired superconductive properties.

Abstract: A method of printing on an ink receptive coating (12) which enhances the density of images printed on non-ink receptive substrates (10) by ink-jet techniques is pro­vided. The substrates, such as transparent polyester films, are coated with a layer of an material to a thick­ness which promotes controlled latent lateral diffusion of the printed ink dots (14a-c). The lateral diffusion is microscopically observed to begin immediately after print­ing, eventually ceasing as the vehicle of the ink is suf­ficiently spread and evaporated by the lateral spreading. The optical density of the image increases as the ink diffuses, reaching a maximum density that is considerably greater than otherwise possible without such an ink-coat­ing system and avoids the undesirable surface coalescence of drops (14) which causes a puddled appearance in films not employing latent spreading. Sheets of such printed imaged media are stored in removable sheet protectors of a vapor permeable, water absorbent material such as cellu­lose acetate, such that dot spread is controlled within the teachings of the invention.

Abstract: Print enhancement circuitry (421) to enhance the printed image produced by a laser beam printer is interposed between the character generator circuits (411) and the laser drive circuits (391) to modify the laser drive signals provided by the character generator circuits (411). Bit data representing successive lines of the bit map for a desired image are stored in a first-in first-out (FIFO) buffer (101). The bit pattern sample window (109) having a central cell (bit) (111) and a selected (arbitrary) number of neighboring bits is compared to a number of matching bit patterns or templates (77-95), each of which is associated with an error element or cell. When a logic matching network (103) detects a match, a modification signal associated with a unique compensation cell (bit) (121-135) is generated. The sample window central bit (111) is then replaced (modified) with the unique compensation bit required by the matching template. In this manner, all bits in a desired bit map (90), or set of bit maps, are examined and their corresponding laser drive signals modified to compensate for the errors associated with the matched templates in a piece-wise manner.

Abstract: In a termination machine (20) for inserting wires (22) into insulation displacement slots (32) (see Fig. 8) of terminals (24) of an electrical connector (26) during each termination stroke, a connector locating member (80) moves together with a termination blade (128) to precisely position the connector (26) for termination. A wire locator (144) moves together with the termination blade (128) and moves the wire (22) into a guide slot (148) in a template (146) over the connector (26). When the blade (128), the wire (22) and the connector (26) are in precise alignment, the termination blade (128) completes the termination stroke. A feed slide (62) and pawl system (72, 78) moves the connector (26) in steps equal to the terminal centerline spacing (X) (Fig. 9) and the feed stroke is selectively adjusted to skip voids where terminals (24) are not to be terminated with wires (22).

Abstract: A detector and alarm is provided for monitoring air pressure variations in a monitored space, which variations correspond to an intrusion. An infra-sonic detector includes a micro­phone (11) or the like and a low pass filter to retain only low frequency infra-sonic signals or a bandpass filter to retain a particular range of frequencies between approximately 5 Hz and 12Hz. The instantaneous infra-sonic signals are com­pared (14) against a variable reference signal, which is a volt­age lagging or delayed variant of the instantaneous signals. In this manner the detector is self adjusting for slow vari­ations in the instantaneous signals but responds immediately to rapid variations to trigger an alarm. In one embodiment the detector only senses negative going air pressure changes to trigger an alarm in order to minimize the incidence of false alarms.

Abstract: An optical ladder has several optical sensors D1 to D6 connected in parallel between an input bus 3 and an output bus 40 via respective input couplers 11 to 16 and output couplers 121 to 126. Radiation from a source 2 is supplied to the input bus 3 from where it is coupled to each sensor D1 to D6 in turn after passage through any upstream input couplers on the input bus. A detector 5 receives radiation on the output bus 40. The output couplers 121 to 126 are connected so that radiation from the sensor D1 closest the source 2 has to pass through the output couplers 122 to 126 of the other devices D2 to D6, whereas radiation from the sensor D6 furthest from the source 2 passes directly to the detector 5 without having to pass through the other couplers 121 to 125. In this way, all the input and output couplers 11 to 16 and 121 to 126 can have identical coupling coefficients.

Abstract: The invention is both a system and method for continuously separating heavier from lighter isotopes of a particular element, such as zirconium. The system comprises a housing (3), a column assembly rotatably mounted with respect to the housing which includes a plurality of vertically oriented separation cells arranged in a circle, each of which contains a packing material, both a feed electrolyte source and a barren electrolyte source, each of which has an outlet mounted in the housing for continuously introducing either a feed electrolyte or a barren electrolyte into each of the cells as they rotate past the outlets, and upper and lower electrodes disposed over the upper and lower ends of the separation cells for inducing the electro-migration of the lighter zirconium ions toward the lower ends of each of the separation cells. A drain assembly disposed beneath the column assembly continu-ously collects isotopic enriched electrolyte from the bottom ends of the separation cells. The speed of rotation of the column assembly is coordinated with the rate of eluent flow through the cells so that the same segments of the annular tray of the drain assembly continuously collect eluent enriched in a particular type of zirconium isotope.

Abstract: Three or more conversion functions are prepared. Only a part of the conversion functions are extracted therefrom to specify provisional conversion functions. A reference solid-pixel number and imaginary solid-pixel numbers for each provisional conversion function are computed through an imaginary exposure for a quarter halftone-dot block on a scanning line. The imaginary solid-pixel numbers are computed in response to new image signals which are obtained by converting an image signal through the respective provisional conversion functions. 
     Then, each of the imaginary solid-pixel numbers is compared with the reference solid-pixel number, thereby a most-approximate conversion function, which gives a solid-pixel number most approximate to the reference solid-pixel number, is selected among the conversion functions. An exposure control signal is generated by comparing an image signal which is obtained by converting the image signal through the most-approximate conversion function with a corresponding screen threshold value.
