Patent DE-3224680-A1 (DE)
Title: Hydrostatic axial face seal
Inventor: KUPKA DIETER
IPC: F16J15/16
Filed: 1982-07-02
Abstract: In axial face seals with pairs of rings of which in each case one ring rotates with the shaft and slides with one front face against the front face of another, non-rotating ring, the rotating sliding ring of a pair of rings is rendered axially displaceable by means of a piston which can be displaced axially under the action of a pneumatic or hydraulic fluid and does not rotate with it or by means of a corresponding inflatable bellows or expanding body made of metal. In contrast to an earlier proposal of the same applicant, P 3120185.7 and P 3212939.4, a more recent proposal, according to which on the one hand, the non-rotating base ring, i.e. the radially immovable base ring, itself was designed as such a piston, or the wearing sleeve situated on the rotating stirrer shaft was designed as an axially movable piston ring, in the new design according to the invention the rotating sliding ring itself is designed as an annular piston with the ability to move axially and, simultaneously radially, whereby the static sealing of the shaft sleeve relative to the rotating stirrer shaft can be provided and the sleeve itself does not have to be moved. The subject-matter of the new invention is that a considerable simplification of the axially and radially movable body, the efficient reduction of the overall height and a very much simplified assembly of the built-in components are possible. The seal housing is furthermore fitted with an automatic lubrication, coolant and counterpressure pump which is driven by the rotating stirrer shaft and, in conjunction with corresponding safety and control valves, allows the overall supply to the axial face seal in an adjustable manner. <IMAGE>
Patent DE-3231386-A1 (DE)
Title: Engine
Inventor: DOSE GEORG
IPC: F01C1/40
Filed: 1982-08-24
Abstract: The invention relates to an engine, which can be constructed as an internal combustion engine or a steam engine inter alia, with various shapes of bodies of revolution. An outer body of revolution (=housing, engine block) concentrically surrounds the inner body of revolution, which is mounted rotatably in it and is connected to the engine shaft. The cavity between the bodies of revolution corresponds approximately to the swept volume in Otto engines but no compression takes place in it. It is in this cavity that the interacting parts operate, one sort being secured on the outer body of revolution and the other on the inner body of revolution. At least one sort is movable and can yield to the other by rotation or retraction. Variable chambers, in which the power cycle and the exhaust cycle alternate, are thus formed between the interacting parts. The motion of the interacting parts can be used to give automatic control and to feed the operating medium into the chambers. The rotary motion can be transmitted either at the shaft or by the housing. The outer body (1) of revolution, the inner body (2) of revolution, at least one pair of interacting parts (31 and 32), seals (4), bearings (5), feed lines (6), exhaust (7), compression device (8) shown schematically, ignition (9), combustion chamber (10), exhaust chamber (11). <IMAGE>

Title: Identity card fitted with a photograph of the holder
Inventor: WILLMANN GEORG
IPC: B42D25/00
Filed: 1982-09-09
Abstract: The invention relates to an identity card which is secured against forgery by replacing the photograph present on the card. For this purpose, the photograph is fitted on one part or its entire surface with regularly or irregularly arranged perforations of any desired shape. By the application of pressure and heat, ridges are formed in the perforations from the plastic films surrounding the photograph on both sides, which ridges make subsequent exchange impossible. It is expedient to provide the photograph with a bondable or weldable coating in order to improve the connection between the photograph and the layers of plastic. A further expedient measure is to construct the contour line of the photograph and the plastic film receiving the latter in an undulating shape. <IMAGE>

Title: Method and device for feedback on pushbuttons
Inventor: KREUTZ RONALD DR
IPC: H01H9/16
Filed: 1983-01-18
Abstract: The invention relates to a method and a device for electrical feedback of the initiation of a function or of a signal on a pushbutton after its operation, in contrast to the previous tactile, acoustic or visual feedback methods. This is done by means of a metallic contact (2) on the pushbutton surface, via which an electrical, physiologically detectable voltage pulse is passed to the skin surface of the user's finger (3) which is operating the pushbutton and is touching the contact. The invention also relates to a device for the feedback circuit. In consequence, it is generally possible to equip apparatuses for inputting data and texts, especially for use at high pushbutton operating frequencies, with pushbuttons having virtually no movement, for example membrane pushbuttons or piezo pushbuttons, or with pushbuttons having no movement, that is to say sensor pushbuttons, since the invention makes possible non-acoustic and non-visual feedback, in synchronism with each operation of the pushbutton, of the initiation of a function or of a signal when a pushbutton is operated. <IMAGE>

Title: Grating-like sliding shutter
Inventor: SALOMON ADAM
IPC: G03B9/40
Filed: 1983-08-13
Abstract: The invention relates to a sliding shutter for cameras. The object of this invention is to shorten the exposure time and is achieved by using a grating-like sliding shutter which consists of three juxtaposed, movable slides ABC (1, 2, 3) fitted with a number of openings. In the initial position (phase 1), the slides A and B (1 and 2) cut off the light from the negative material. The slide C (1) serves to regulate the openings. The width of the latter and the rapidity of the exposure can be controlled automatically - by applying a substance for electrical light measurement to the apertures of the slide A. During exposure (phase 2), the slide A (1) firstly moves and uncovers the openings of the slide B (2). After the exposure of these sections, the slides A and B are jointly displaced further, the remainder of the photosensitive material being exposed. After the slide A has reached its end position, it terminates its travel in common with the slide C. The slide B pushes its openings into the cover of the apertures of the slide A and likewise terminates its travel. <IMAGE>

Patent DE-3344204-A1 (DE)
Title: Multiplex method for transmitting high-quality digitised stereo sound signals
Inventor: SCHAAF CHRISTOPH DIPL ING
IPC: H04H20/81
Filed: 1983-12-07
Abstract: In order to be able to transmit high-quality digitised stereo sound signals, for example a stereo sound broadcast program, with associated additional information in each case via a DSV2 system or a higher-speed system, a multiplex signal is formed according to the invention, whose pulse frame PR is sub-divided into two half-frames HR1 and HR2. The first half-frame comprises a frame alignment word RK (12 bits), eight double code words DC (each of 30 bits), four bits of additional information Z assigned to the sound signal, and a further eight double code words DC. The second half-frame HR2 is identical to the first half-frame except for the frame alignment word RK, which is replaced here by 12 bits of additional information. The double code words DC comprise two code words C (each 15 bits), which in turn comprise one digitised sampling value A (14 bits) and one error protection bit F. A pulse frame period of 1 ms produces a total data stream of 992 kbit/s, where 20 kbit/s are allotted to additional information and 960 bit/s to the stereo sound signal. The multiplex signal can be transmitted by its own frame alignment word RK via every digital multiplex system whose useful bit rate is greater than/equal to 992 kbit/s, without being in any way dependent on the structure of the transmission system (Figure). <IMAGE>
