Abstract: The invention relates to an optoelectronic rangefinder having two linear video scanners (1, 2) onto which there are projected in each case sections of mutually corresponding rows of two images derived from an object (GE). That positional displacement of the scanner signals of one video scanner with respect to those of the other video scanner in which a maximum correlation of the scanner signals occurs represents a measure of the range of the object (GE). The aim is to eliminate measuring errors which arise in the event of too uniform an illumination of the individual scanner elements. This is achieved according to the invention by providing a light source (LE) which is connected to the rangefinder and whose light beam illuminates at least one part of the object, this part being situated inside the angular ranges ( alpha 1,  alpha 2) of two optical devices via which the images projected onto the video scanners (1, 2) are obtained. The field of application includes rangefinders for photographic and electronic cameras. (Fig. 1). <IMAGE>

Abstract: Diapositives are mounted in a strip formed by a pair of flexible sheet members each having at least two picture openings therein in side-by-side relationship and the sheet members are fastened to each other in face-to-face relationship mutually offset by a single picture opening. The frame is interposed between the sheet members and a diapositive is moveably positioned within an opening in the frame. The thickness of the frame is greater than that of the diapositive so that a diapositive is freely moveable within a frame opening and has play between the sheet members. An apparatus for projecting the strip mounted diapositives is provided with a pair of cassettes one of which contains a strip in which the diapositives are mounted and the second cassette contains a strip without any diapositives. The ends of the strips are automatically connected to each other for successively introducing the diapositives into the apparatus.

Abstract: A pull-push switch has one or two stationary contacts (25,26) and one U-shaped elastic movable contact (23) with two legs (23,24) which, when not deformed, are adapted to resiliently make into contact with the stationary contacts. A cam (31) is securely mounted on an operating shaft which can be axially shifted between the pulled and pushed positions. The cam has a small-diameter cylindrical portion (29) contiguous with a tapered intermediate portion (28) which in turn is contiguous also with a large-diameter cylindrical portion (30). The legs of the elastic movable contact are so positioned that they are normally maintained in contact with the peripheral surface of the cam as it is shifted in unison with the operating shaft so that when the shaft is pushed or pulled, the legs of the elastic movable contact rest on the small-diameter cylindrical portion of the cam and subsequently make contact with the stationary contacts, whereby the switch is closed. When the operating shaft (1) is pulled or pushed,the legs of the elastic movable contact ride on the large-diameter cylindrical portion of the cam so that they are forced to bend outward or moved away from each other and from the stationary contacts and consequently the switch is opened.

Abstract: An infrared random access imager system is disclosed which includes a scanning mechanism, a random access imager detector matrix (22), and a video signal processor. The scanning mechanism scans the infrared energy emanating from a scene in the field-of-view. The random access imager detector matrix (22) stores charges as charge packets representative of the infrared energy impinging thereon and the video signal processor processes the charge packets into video signals. Each random access imager detector matrix element comprises a modified charge injection device, which has two electrodes (24, 42) per unit cell, and horizontal (30, 32, 34) and vertical (42, 44, 46) metal-lead address lines, to which is added a third electrode (36). The third electrode (36) is a transfer gate which transfers the charge of the detector element into a read line (42) and keeps the charge from one detector spilling into the detector well of and adjoining until cell. Thus, charge carriers are created by photoabsorption and collected in the detector well (storage well). Upon activation of a charge transfer electrode (36, 38, 40) the charge passes over the dc transfer gate (36, 38, 40) (word line) and down a read line (42, 44, 46) (bit line) to an output charge collector means (48, 50, 52) for processing by the signal processor.

Abstract: The invention relates to equipment of the "camping chair" type and aims to afford maximum comfort in use, transportation or storage, taking up a minimum of space. It comprises a seat (1) and a back (2) consisting of pieces of fabric mounted on sprung winders (31, 32). The strength in terms of width is provided by two parallelograms (41-44) (and (51, 54), their locking in an open position being provided by braces (7) using contact with the ground in order to operate. The compensating springs (61, 62) balance the force of the winders (31, 32). The parallelogram and spring assembly retracts into the legs of the chair in the first phase of folding. In a second stage, it is necessary to tilt the back forwards. This firstly causes the rear legs to fold by means of a gear articulation (90), and then causes the front legs to fold by means of the linkage (9, 10, 11). The grips (12) are used for folding and for transportation. <IMAGE>

The basket (14) is removed by decomposition or melting and extraction or evaporation or incorporation in one or both of the powdered alloys.

Un premier et un second transistors a emetteur commun (Q1, Q2) sont amenes a fonctionner a des densites de courant emetteur differentes au point de declenchement, necessitant ainsi l'application d'une (Alpha)VBE a une premiere resistance (R2) branchee entre les bases du premier et du second transistor afin de provoquer la commutation de la sortie du circuit. Le courant a coefficient de temperature positif qui traverse la premiere resistance pour engendrer (Alpha)VBE est ajoute a la base du second transistor a un courant d'un coefficient de temperature negatif circulant dans la deuxieme resistance (R3). Ceci permet de creer le courant d'entree requis possedant une intensite et un coefficient de temperature controlables. Le courant d'entree peut etre fourni par l'intermediaire d'une resistance supplementaire (R4) a la base du second transistor pour creer un point de declenchement de tension d'entree ayant une grandeur et un coefficient de temperature controlables.
