Patent EP-0319788-A1 (EP)
Inventor: PIETZSCH JOACHIM DR-ING
IPC: H04B10/06
Filed: 1988-11-24
Abstract: Frequency shift keying (FSK) is advantageous for optical heterodyne reception, since no additional modulator is required in the transmitter. However, according to the present state of the art, signals subjected to frequency shift keying cannot be demodulated with homodyne receivers. In order to reduce expense in the transmitter and, where the transmission of high bit rates is involved, in the receiver also, an optical heterodyne receiver is proposed which, following on from a 90 DEG  optical-electrical hybrid (H) on the input side, contains one or two demodulators (DEM1, 2) connected in parallel on the input side, in each case comprising two branches which contain an analog multiplier (M1) and a delay component (T1) and in which the signals of the branches are combined by an adder or a subtracter (SUB1). <IMAGE>

Abstract: A strut assembly having first (10) and second (16) sections pivotally linked together. An overlying sleeve (36) is extendable to lock the sections together in the extended position and retractable to allow folding of the sections relative to one another. A member (44) is arranged at the joint between sections and biased to extend outwardly into interference with the path of extension of the sleeve (36). A link (26) linking the first and second sections cooperates with the member (44) to retract same when the strut assembly is collapsed in order that the sleeve (36) will automatically lock the sections together when the assembly is again extended.

Abstract: Sheet transporting apparatus including a pair of rollers (13, 14) forming a sheet transporting nip (12), and adapted, when in an initial position (Fig. 1a), to engage the leading edge (17) of a sheet (11) delivered thereto, and means arranged to produce an orbital motion of the rollers one about the other so as to progressively change the direction of motion of the sheet while the sheet is advancing through the nip (Figs. 1b - 1d). 
     In one preferred form of the apparatus, the nip between the rollers, in its initial position, is oriented so as to receive a sheet delivered thereto in a generally horizontal direction (Fig. 1a), and at the position in said orbital motion furthest from the initial position (Fig. 1c) is oriented so that it is advancing the sheet generally vertically downwards. In this form, the apparatus is suitably used in conjunction with a generally vertical sheet receiving tray to provide a sheet inverting stacker. 
     In another preferred form, the sheet transporting apparatus is used in conjunction with a generally horizontal sheet receiving tray to provide a sheet stacking apparatus capable of reliably stacking sheets over a wide range of sheet lengths without any adjustments being needed to the locations of the rollers or the tray.

Abstract: A photostimulable x-ray converter member is dis­closed for digital radiographic applications which comprises a composite of phosphor particles suspended in a matrix of a solid organic polymer having an optical refractive index closely matching the optical refractive index of the phosphor particles. Said composite phosphor medium further exhibits this refractive index match at the wavelength of the energy source employed to readout a latent radiographic image pre­viously stored by X radiation in the phosphor. The particular phosphor material being employed is barium fluorohalide activated with europium ion whereas the preferred thetic organic polymer is a polysulfone exhibiting sufficient mechanical strength to form a self-supporting void-free composite with the suspended phosphor having a surface area of at least one-half square foot. A method to produce said composite x-ray image converter medium is also disclosed along with a digital radiographic imaging system and method employing said x-ray image converter medium. The barium fluorohalide phosphor may be modified with Group 1A and/or 3A impurity ions to improve further the refractive index match.

Abstract: Mowing appliance with two cutter bars (2) which oscillate transversely to and fro and shear off the mowing material oppositely to one another and are equipped with a row of cutting edges (4) arranged in a zigzag form. In the mowing appliance according to the invention, these cutter bars (2) are in the form of an arc of a circle and are connected, via struts (11) extending rearwards from the middle region, to a pivot point (10) which is arranged in the rear region of the mowing appliance and which coincides approximately with the centre point of the circle arc (6) of the cutter bars (2). The oppositely directed to-and-fro pivoting of the cutter bars (2) in the form of an arc of a circle is obtained in that the struts (11) are pivoted to-and-fro so as to oscillate by a small angular amount in relation to the pivot point (10), this being effected by means of an eccentric drive (13) from a motor (15) arranged above the struts (11). This affords not only a simple constructive design of the mowing appliance, but, because of the relatively low outlay in terms of force for the cutting used here, shearing off between two cutting edges (4), it becomes expedient to use accummulator-fed electric motors, this affording desirable acoustic advantages especially in the private sector. <IMAGE>

Abstract: A hand tool for applying on a substrate a film carried on a supporting film comprises a housing which contains a feed reel and a rake-up reel for the supporting film. The two reels are placed on pintles rotatably mounted in the housing. At least one reel is associated with a rewind stop, the two pintles are interconnected by toothing with a friction clutch which acts in the direction of rotation, and the supporting film, which can be wound off the feed reel, is guided on an applicator element which projects from the housing and presses the film side of the supporting film against the substrate. The supporting film then re-enters the housing and is wound onto the take-up reel. In order to improve such a hand tool by reducing the number of components and simplifying its manufacture, the toothing (18, 19) is incorporated in the corresponding pintle (8, 9) and the friction clutch forms and integral part of the toothing (18, 19).
