Abstract: Apparatus for determining displacement of an object comprises a light source (1) for propagating polychromatic light along a path to a detector (7). Radiation modulation means such as a filter (5) is provided in predetermined fixed location with respect to the source (1) and the path of the light is adjusted in response to a displacement of the object such as to vary the distributed spectral content of the light reaching the detector (7). The detector comprises first and second photoresponsive elements (10, 11), of differing responsivity with respect to wavelength, and a microprocessor (14) receiving signals from the photoresponsive elements. The microprocessor calculates the colour of the light incident on the detector (7) as represented by two or more parameters on the chromaticity (CIE) diagram, and interprets the colour of the light incident on the detector (7) in terms of the displacement of the object.

Abstract: The invention relates to a method of manufacturing a curved automobile glass pane. The glass sheet heated in a continuous roller conveyor furnace to bending temperature, is picked up by a traveling suction device and transported to a curving station adjoining the furnace. In the curving station the glass sheet is deposited onto a curving device which is comprised of a curving-form frame and a curving form which form occupies the interior space of the frame. The suction device is withdrawn, and a hot gas stream is applied from above, which stream impinges on the glass sheet, whereby said sheet is forced against the curving device comprised of the curving-form frame and interior curving form. Then the glass sheet is lifted from the interior curving from by means of the curving-form frame which frame now serves as a support ring, and sheet is transported to the neighboring cooling station.

Abstract: Mounted in the spindle head (13) are bevel gears (18, 19) which are arranged in mirror image to the pivoting axis (14), at 45 DEG  to the spindle axis (15) and a drive shaft (12), for the spindle head (13) and are in constant mutual engagement. The bevel gear (18) is coupled to the spindle (16) via a shaft (20) and bevel gears (21, 22). Depending on the pivoted position of the spindle head, an axially displaceable coupling part (12a) of the drive shaft (12) can alternatively be coupled to the bevel gear (18) or the bevel gear (19). To pivot the spindle head (13) from the vertical position shown into a mirror-image horizontal position pivoted through 180 DEG , the coupling part (12a) is axially disengaged, the spindle head is pivoted and the coupling part (12a) is then engaged again. This results in a simple compact construction which enables the precision requirements to be easily met. <IMAGE>

Abstract: The device has an external comminuting element ring (1) constructed as a stator, in the form of a cylinder, on the outer surface (3) of which slots (5) aligned approximately perpendicularly with respect to the central axis (M) are arranged, whilst the inner comminuting element (2) constructed as a rotor has two vanes (18) whose end faces are constructed as knife blades. In order to increase the performance of the device without requiring a relatively large rotor speed, an outer ring (5) with slots (6) is attached around the stator (1) by means of screws in such a way that it can be moved up and down and possibly also in a rotating manner, by which means principally the width of the slots can be adjusted or narrowed. As a result, a higher output speed of the liquid and thus a higher degree of efficiency is obtained with the same rotor performance. <IMAGE>

Abstract: Procédé et appareil de reformatage de signaux de télévision couleur MAC dans le but de réduire la largeur de bande. Les composantes de chrominance et de luminance sont disposés en série sur une base ligne par ligne, la composante de chrominance n'étant pas comprimée ou l'étant de manière minime. Le rapport d'aspect est réduit du rapport d'aspect standard au moyen d'une porte (5) qui tronque les bords et envoie les signaux MAC dans les mémoires (10, 11) à des fins d'expansion temporelles ultérieures. Etant donnée qu'un tube d'image de télévision normal effectue un surbalayage, les bords de l'image ne sont jamais affichés et n'ont pas besoin d'être transmises ou enregistrés. Le signal reformaté peut-être rendu compatible avec un signal composite standard par une simple expansion (22) et modulation de la chrominance qui est ajoutée à la luminance (25) le signal compatible possède un temps vidéo actif plus court et un rapport d'aspect plus petit.

Abstract: If in the case of a load (R₁) powered by a battery (6) the detection means (10) detect a battery voltage below a first threshold value (V₁) defined by an adjustable voltage source (20), first time-measurement means (40, 50) measure the time interval during which the load (R₁) is powered by the battery (6), at a voltage below this threshold value (V₁). If subsequently the load (R₁) is switched off and not connected to the mains voltage  via  a power-supply circuit (1), the battery (6) is discharged by a discharger (30). Second time-measurement means (40, 60) measure the time interval during which the discharger (30) is operative until the detection means (10) detect a battery voltage below a second threshold value (V₂), which is defined by a voltage source (25) and at which the battery (6) may be regarded as fully discharged drained. After comparison of the sum of the time intervals measured by the first and the second time-measurement means with the reference value, correction means (70) correct the first threshold value (V₁) in such a way that during a next discharge the time measured is better in agreement with the reference value.

Abstract: There is described a memory device that contains a static RAM-memory. This is provided with data input and date output registers, an address register, and a control register for storing various control signals. The RAM has three principal modes:
     a. in a normal mode, all registers are accessible externally so that the memory may fulfill its standard function,   b. in a scan-state, all the cited register constitute a synchronous shift register that may be serially written with a test pattern and serially read with a result pattern; in this way the memory may be subjected to a test according to the scan test principle,   c. in a self test state the communication with the outer world is shut off, the address register counts through successive addresses, the memory is cycled through read-modify or read-modify-read operations, and the data read is conversed to a signature pattern for subsequent scan-­out.   
     In this way a quasi stand-alone test facility is realized. Various additonal features may be implemented.
