Abstract: The machine for the more effective utilisation of heat uses a working substance which is a mixture of two pure substances with different boiling points. The machine has two columns (Cd,Cg) operating at different pressures. In the first column a quantity of heat (Qo) is supplied to the base of the column. This heat causes one of the components of the working substance to evaporate and flow to the upper part of the second similar column (Cg) which operates in a reverse manner. Quantities of heat are transferred between the two columns at different heights above the base of each column.

Abstract: Bei einem Verfahren zum opto-elektronischen Prüfen eines Flächenmusters an einem Objekt, insbesondere einer Leiterplatte, wird eine Mikroprüfung vorgenommen, indem zeilenweise aufgenommene Bildelemente Bildpunkt für Bildpunkt einer Folge von Bildoperationen zu einer Abmessungs-/Abstandsprüfung unterzogen und das jeweilige Ergebnis mit dem entsprechenden aufgenommenen Bildpunkt verglichen wird. Gleichzeitig wird eine Makroprüfung vorgenommen, indem die aufgenommenen Bildpunkte in Bildfeldern zusammengfaßt und jeweils auf eine einzige charakteristische Bildinformation reduziert werden, worauf wieder ein Vergleich, in diesem Fall jedoch mit der entsprechenden Bildinformation eines Referenzbildes, erfolgt. So lassen sich in Echtzeit Flächenmuster; beispielsweise Leiterplatten, sowohl auf kleine, visuell kaum sichtbare Fehler als auch auf Makrofehler hin schnell und vollautomatisch überprüfen.

Abstract: A connector for monomode optical fibres comprises two connectable housings in each of which is secured the end of an optical fibre which is substantially coaxially aligned with at least two light displacement means which produce a light beam with a predetermined form from lighttransmitted along the optical fibre. The light beams from the two housings are complementary so that a light beam from either housing is focussed on to the end of the optical fibre in the other housing when the two housings are connected. 
     The light displacement means may be convex or concave lenses, selfoc lenses, prisms or combinations of these. The light beam from each housing is preferably parallel but one can be divergent and the other covergent. They may also both be divergent with an additional lens between the housings.

Abstract: A linear capacitive encoder is utilized for detecting and encoding the position of a movable member such as a print bar (5) in a dot matrix impact printer. An eight-phase signal is capacitively coupled to one plate of a linear capacitor (A5-A8) mounted on the movable print bar. When the print bar moves the phase of the coupled signal changes with respect to the phase of the signal on the other plate of the capacitor, producing an analog signal representing incremental movements of the print bar. The analog signal is amplified and filtered (41, 42) and then converted to a TTL signal representing the position of the print bar. Present position of the print bar is compared to previous positions of the print bar to derive signals representing the present direction of movement, direction change and incremental movements of .0254 mm. Built-in error or hysteresis is added to the direction and direction change signals to prevent false direction changes due to noise. The .0254 mm signal and the direction change signal input a microprocessor which generates print position command signals at a selected dot density based on data stored in an output table which takes into account print hammer flight time and compensates for the sinusoidal motion of the print bar. An absolute reference point is established by the processor at each direction change of the print bar motion.

Abstract: A simplified object positioning system for use with automatic product assembly equipment for precisely positioning objects to a particular location within a predetermined area once the object has been moved to within a minimum distance from the particular location. The system includes a support surface coupled to a drive source that is capable of moving the support surface in any direction along a given plane and/or about an axis perpendicular to the given plane in response to drive source positioning signals. The system also includes a module for sensing object position which comprises a generally planar set of photosensitive elements electrically divided into a plurality of groups and positioned to sense a portion of the light from a light source that backlights the object to be positioned located on the movable table. The light sensing elements overlie the space between a silhouette or shadow of the backlighted object and a slightly enlarged negative object image for the purpose of sensing spacing-size related light passing through this space, at a plurality of different locations, so that electrical signals representative of the spacing size at these locations can be generated and subsequently employed to cause the drive source to adjust the negative image to object silhouette spacing to a predetermined size and thereby precisely position the object to the particular location within the predetermined area enclosed by the slightly enlarged negative object image.

Abstract: @ A vertical type screening machine for granular material comprises a housing. A rotary drum assembly is rotatably mounted within the housing and comprises a drum having a substantially vertical rotary axis and a helical blade helically wound around a circumferential surface of the drum. A cylindrical screen member disposed between the drum assembly and the housing cooperates with a peripheral wall of the housing to define therebetween a first chamber and cooperates with the circumferential surface of the drum to define therebetween a second chamber. The granular material to be screened is introduced into the top of the'second chamber. Upon the rotation of the drum assembly, the granular material introduced into the top of the second chamber is moved toward the bottom of the second chamber by the helical blade and due to gravity. During the movement of the granular material toward the bottom of the second chamber upon the rotation of the rotary drum assembly, the granular material is subjected to a centrifugal force by the helical blade so as to be moved radially outwardly toward the screen member so that granular material having a relatively small size contained in the introduced granular material is introduced into the first chamber through the screen member. The remaining granular material within the second chamber is discharged from the bottom of the second chamber.

Abstract: In a vibration type force detector devised so as to detect the magnitude of a force by measuring the vibration frequency of a vibration element vibrating in a magnetic field with the force loaded, the exciter employed for exciting the vibration element to make the same continue non-decaying vibration with an exciting current fed back from the voltage developed on the vibration element is improved so as to output an exciting current proportional only to the electromagnetic force generated by the vibration of the vibration element without being affected by the voltage drop made by the exciting current on the vibration element. The voltage drop component in the voltage developed on the vibration element is cancelled with an offset voltage prepared by dividing the output voltage of the exciter. Thus the exciter can amplify only the e.m.f component, if the offset voltage is adjusted to be equal to the voltage drop on the vibration element. Therefore, the vibration element can be excited effectively irrespective of its resistance and/or mechanical Q-value.
