IPC: G08C25/00
Filed: 1979-05-23
Abstract: Ein faseroptisches Meßgerät zum Messen physikalischer Größen, wie Lage, Beschleunigung, Druck, Dehnung, Temperatur, Kraft, hat eine Lichtquelle und einen vor der Meßgröße beaufschlagten Geber, der das ausgesandte Licht in Abhängigkeit vom Augenblickswert der physikalischen Größe beeinflußt. Ferner sind Detektoren zur Umwandlung des vom Geber beeinflußten Lichtes in elektrische Signale vorhanden. Das vom Geber beeinflußte Licht wird in mindestens zwei Komponenten aufgeteilt, die Meßkomponente und mindestens eine Kompensationskomponente. Das Meßgerät enthält elektronische Glieder zur Gewinnung eines Meßwertes aus der Meßkomponente und einer Steuergröße aus der Kompensationskomponente. Mit der letztgenannten Steuergröße wird entweder die Lichtquelle oder die Detektorelektronik gesteuert zwecks Stabilisierung der Optoelektronik und Faseroptik des Meßgerätes.

Abstract: A method of reproducing a mixed content original (e.g. one comprising half-tone and printed matter) comprises operating a recording device according to a selected one of a plurality of different algorithms. The algorithm used is selected according to the rate of change of reflectance or transmittivity of the zone being reproduced. In the example two reference values are established to define three ranges and the instantaneous value of the rate of change is compared therewith to determine in which of the three ranges it lies. For one range the currently operating algorithm is maintained, for a second range one algorithm is used and for the third range a second algorithm is used. 
     The Figure shows facsimile apparatus comprising a threshold switch 7 which determines which range contains the instaneous value of the rate of change. The switch 7 provides an output to the threshold devices, 15, 17 which determine the mode of operation of the recording device (printer) 19.
Patent EP-0010774-A1 (EP)
Inventor: BIELLI PAOLO
IPC: H01Q/
Filed: 1979-11-05
Abstract: The method for tracking an object emitting a circularly or linearly-polarized electromagnetic wave utilizes only the TE21 mode signals, extracted by means of two pairs of slots (A, A'; B, B') located on planes at π/4 in the antenna feed. The signals of a slot pair are substracted one from the other and the resulting signals are made proportional to the antenna displacement from nominal object direction. This is obtained by making an angle ϕ, that determines the angular position of the plane passing through a pair, equal to half an angle a, that determines the angular position of the polarization plane. The system that carries out the method is also described.

Abstract: An image represented as an array of digitally valued picture elements is selectively reduced or expanded in size by addition or subtraction of rows and lines of picture elements at positions which are the closest approximation to the newly scaled base, the picture elements corresponding to grey scale values. Reproducing a given image is scanned by photodetector elements (18). The added lines are duplicative of the next adjacent line. Subsequent lines of picture elements are shifted to close the gaps. A dot generator array (such as ink jet array, cathode ray tube, electrostatic or thermal recording system) responsive to the digital values of the picture elements generates the image in scanning fashion across a copy sheet at a modified scale factor in a single or in successive scans, which may occur at the same location or after transmission of the digitally valued pictured data to a different location.

Abstract: A sleeving method wherein a metal sleeve (16) is inserted into a tube (10) so as to bridge a defective region of the tube (10). The sleeve (16) has teeth (40) on the outside thereof which tightly contact the inside surface of the defective tube (10) and create a labyrinth-type seal. The sleeve (16) is then internally pressurized in the area where the teeth (40) are located. This expansion of the sleeve (16) causes the teeth (40) to engage the tube (10). The other end of the sleeve (16) can then be either similarly attached to the tube (10) or welded to the tube (10). Next, the remainder of the sleeve (16) is expanded which causes the sleeve (16) to shrink in length which results in the teeth slightly penetrating the inside surface of the tube thereby creating a leak tight seal therebetween.

Abstract: A wheel alignment apparatus and method are provided for use in aligning the front wheels of a vehicle. The wheel alignment apparatus includes a dynamic wheel aligner (10) which determines the dynamic toe angle and dynamic camber angle of a wheel using the axial displacement of rolls (12, 14) upon which each front wheel is rotatable. The wheel alignment apparatus stores these dynamically determined values and stops the rotation of the rolls (12, 14). After predetermined time delays, an alignment operator makes adjustments to the toe and camber angles of the weel so that these angles are within a desired range. The changes in the toe angle and camber angle during alignment are determined by the apparatus and combined with the dynamically determined toe and camber angles. As a result, the alignment operator continuously has a visual indication of the toe and camber angles during alignment. The wheel alignment apparatus also removes unwanted changes in the toe angle which occur during the predetermined time delays so that the visual indication accurately reflects the dynamic toe angle.

Abstract: By removing the key from the dashboard, it is possible simultaneously to lock the engine bonnet, where the device is situated, and to disconnect all the elements of the motor vehicle. The extraction of the key causes the closing of a microswitch (19) permitting an instantaneous drawing-off of current in order to start up a small self-braking motor (10), the shaft (28) of which supports a system of three cams (29, 30, 31), one of which closes the microswitch (19) which has permitted the starting-up, and closes a pivot locking the bonnet. In order to deactivate the device, the key is reintroduced, thus starting up again the motor (10) which, with the second cam (30), closes another microswitch (20) unlocking the closing pivot. The third cam (31) actuates a lever (32) closing and opening the pivot. When this lever (32) closes, it actuates a pusher which deactivates the current. <IMAGE>
