Title: Method of producing a picture postcard
IPC: B42D15/02
Filed: 1982-06-15
Abstract: To produce a picture postcard, in front of whose picture side there is arranged a flat structure which consists of at least two plastic films, which are arranged approximately parallel to one another, are liquid-tight and are connected to one another at their edges in a liquid-tight manner, and is at least partially filled with liquid, a method is used in which a first plastic film having greater dimensions compared to the finished product is placed on a welding electrode shaped to correspond to the welding seams of the finished product. The depression forming due to the sagging of the first film is filled with liquid, then a further film, which likewise has greater dimensions compared to the finished product and has on its side facing away from the first film a self-adhesive layer covered with a protective paper, is placed on the first film. The films are then welded to one another in such a way that separation of the film material takes place along the welding seams and the protective paper is finally removed from the self-adhesive layer and the picture postcard is pressed with its picture side onto the self-adhesive layer.
Patent DE-3222973-A1 (DE)
Title: Circuit arrangement for displaying binary signals by means of antiparallel-connected pairs of light-emitting diodes
Inventor: GLOOR DANIEL DIPL ING
IPC: G09G3/00
Filed: 1982-06-19
Abstract: The circuit arrangement consists of several functional units (Fe1, Fe2, ...) having one or two binary inputs each (1 and 1a, 1b, respectively) and two outputs (Aa, Ab), between which one antiparallel pair of light-emitting diodes each (La, Lb) can be placed, which increases the number of activated light-emitting diodes with the number of connections remaining the same, which is of significance, in particular, in implementing the circuit arrangement as an integrated circuit. The outputs are series-connected and a power source (St) is placed into this series circuit. The current direction is periodically reversed under control by an oscillator (Osz). Each functional unit (Fe) conducts or blocks the current between its outputs (Aa, Ab) as a function of the constellation of binary signals at its inputs (Ia, Ib, ...) and of the current direction. Thus, each of the two light-emitting diodes (La, Lb) placed in antiparallel between its outputs can be periodically, that is to say whenever the current flows in the direction of conduction, either bypassed or connected and caused to light up independently of the other one. If the oscillator frequency is sufficiently high, the human eye perceives the periodic lighting-up of a connected light-emitting diode as a uniform glow. <IMAGE>

Title: Orientation device for the purpose of the yarn-related and/or pressure-related straight severance of a drawn web-shaped product, especially a textile web
IPC: D06H1/00
Filed: 1982-07-07
Abstract: In order, in an orientation device for the purpose of the yarn-related and/or pressure-related straight severance of a drawn web-shaped product, reliably to prevent the formation of creases or waves in the region of the severing device (9), a plurality of straightening tappets (28) are vertically arranged opposite a gap (29) in a straightening plate (11) behind the severing device (9) in the draw-off direction of the web-shaped product (10) and transversely relative to the longitudinal direction of the product. The straightening tappets (28) draw off the product (10) over the straightening plate (11), thereby forming a fold in the gap (29), for the purpose of orientation, until a marking yarn (16) is positioned opposite sensing members (17). These generate control signals, in order to press engagement elements (18) against the product (10), with the result that the product is stopped. In this case, the product (10) is orientated and the severing device (9) can execute a yarn-related straight severing cut. <IMAGE>

Patent DE-3229486-A1 (DE)
Title: Static grooved-tube mixer
Inventor: CUKROWICZ FRANZ
IPC: B01F5/06
Filed: 1982-08-07
Abstract: The static continuous grooved-tube liquid mixer, in which nothing apart from the liquid moves, is intended to mix any desired number of liquid components with one another continuously, while running through. It consists of a number, corresponding to its capacity, of tubes slipped above one another, which receive the flow one after the other and are provided on their inside and outside with specially shaped grooves which extend spirally in such a way that the grooves of one tube cross the grooves of the next tube, as shown in the drawing. In each of the strung-up crossing points, particles of different liquids always meet one another, the crossflow of the liquids causing vigorous frictional eddies to be formed, which effect intensive mixing. In addition to the number of the crossing points, the shape of the grooves, matching the liquids to be mixed, and the selected flow velocity of the liquids are decisive for the achievable fineness of the mixing. The mixer which is easy to handle can be used in oil-mixing establishments, chemical works and wherever relatively large quantities of liquids have to be mixed continuously.

Patent DE-3239177-A1 (DE)
Title: Fire resisting door
IPC: E06B5/16
Filed: 1982-10-22
Abstract: In fire resisting doors, shutterdoors or the like, a problem arises in that, when there is a fire on one side of the door, the door body warps, producing a gap between the door body and the door case, or the door frame, through which hot air, poisonous fumes or the like can escape from the room on fire. The invention solves this problem by equipping the fire resisting door (1), which consists of door body (3) and door case or door frame (2), at least in the area of one door edge, with an additional closing device (4) which responds to the heat of a fire. The closing device (4) contains, as trigger means, a material which changes its state under the effect of heat by expanding, melting, shrinking or by releasing energy, either actively or passively, in another way. In the embodiment in Fig. 1, a bolt (5) is seated on an intumescent cushion (6) of such an expanding material, and, in the event of fire, the bolt is pushed out of the door body (3) and into a recess (11), thus positively locking door body and door case while at the same time sealing the gap between them. This means that the door body (3) is no longer capable of warping on account of the prior response of the intumescent cushion (6). The closing device (4) may bring about a positive or frictional locking, it being possible for the bolt even to be formed of the thermally unstable material itself. <IMAGE>

Patent DE-3246958-A1 (DE)
Title: Rotary-reciprocating piston engine
Inventor: EVERT ALFRED PROF DIPL KFM
IPC: F02B75/28
Filed: 1982-12-18
Abstract: Two pistons acting in either direction form the four working chambers of a four-stroke reciprocating piston engine. The pistons are rigidly connected to one another in their longitudinal axis. The inertial forces of the reciprocating movements are directly converted into compression work in the respectively opposing cylinder chamber. A transmission element is also rigidly connected to the piston axis. This element comprises a disc with corrugated lateral surfaces, which is held between guide rollers. The reciprocating movements of the pistons are thereby converted into rotation. The power of the engine is delivered by way of a gear rim and gear. This transmission element can thus also be used in engines on the principle of the >>Stelzer two-stroke<< for directly obtaining rotational movement for drive purposes. Due to the reciprocating and simultaneous rotary movement of the pistons an automatic control of the intake and exhaust is obtained with precise exhaust and refill in the four-stroke process. The engine has no valves or valve timing, only a rotary axis with a single transmission element, only rotary or reciprocating movements with no undesirable inertial forces. It comprises a minimum of components with outstanding power-to-weight ratio, and a shallow, elongated construction.

Patent DE-3308109-A1 (DE)
Title: Pneumatic rotary actuator
Inventor: WARTHMANN PETER
IPC: F15B15/08
Filed: 1983-03-08
Abstract: The actuator can be used as the actuating element for ballcocks, air flaps and locking systems of plant doors and for all rotary movements customary in the construction of apparatus and machines up to 360 DEG . The actuator is connected coaxially to the devices to be actuated. The torque aimed at and the required angle of rotation can be selected via the thread pitch. The telescoping of the threaded actuating spindle, Item 2, and of the profiled shaft, Item 3, makes it possible to keep the rotary actuator small and compact in construction. A spring return allows closing or opening without compressed air. With the aid of a control shaft which is connected to the profiled shaft, Item 3, and leads out of the pressure space, the actuation condition can be interrogated via 2 limit switches. <IMAGE>

Title: Circuit arrangement for the parallel supply of an AC or three-phase current load network
Inventor: BRAUN RUEDIGER DIPL ING
IPC: H02J3/50
Filed: 1983-03-25
Abstract: In order to supply a load network 11 by means of an actuating element (for example an invertor 2 which is supplied from a solar generator 1) the magnitudes (/Un/, /Uw/) of the output voltage vector Uw and of the load-voltage vector U-n, and the angular difference or the frequency difference between the two vectors are formed by means of suitable measuring devices. An additional magnitude desired value Uz<*> and an additional phase desired value  phi z<*> are in each case formed from input desired values for the real current /Iw/sin phi  and the reactive component /Iw/cos  phi  as well as set parameters R and X for the resistance and the impedance of the coupling circuit, using the relationships /I/<*> = (/Iw/sin  phi )<*> + R/X.(/Iw/cos  phi )<*> and ( phi <*> = (/Iw/ phi cos  phi )<*> - R/X.(/Iw/sin phi )<*>. The additional magnitude desired value is supplied together with the load-voltage magnitude as the desired value and the output-voltage magnitude as the actual value to a magnitude controller which is connected upstream of the amplitude-control input of the actuating element. If the actuating element also has a phase-control input in addition to a frequency-control input, the additional phase-control desired value is supplied to the phase-control input, and the output of a frequency regulator to which the frequency difference between the load voltage and the output voltage is applied is supplied to the frequency-control input. If only a single input is present for controlling the frequency and phase, a phase regulator is connected upstream of this input, to which the additional magnitude desired value I<*> [lacuna] as the desired value and the angle difference [lacuna] as the actual value ...

Title: Extendable and removable roof component for motor vehicles
Inventor: BAUHOF KARL
IPC: B60J7/057
Filed: 1983-07-11
Abstract: In an extendable and removable roof component for motor vehicles, whose cover which closes off one section in the skin of the roof of the vehicle is detachably supported on the vehicle roof at the front end via disengageable swivel joints and at the rear via an extension mechanism, and in which the extension mechanism consists on the one hand of an extension arm which is adjustably mounted on the vehicle roof and can be driven by means of a pinion via a hand crank or a rotary joint and consists on the other hand of a link, which is open at one end, on the cover, it is proposed in order to reduce the number of individual components of the extension mechanism whilst simultaneously increasing the protection against break-ins and avoiding the cover being removed by unauthorised persons, for example by children travelling along in the vehicle, that the extension arm should be formed by means of an arcuate carrier which is provided with a toothing and is held so as to be slidable over a part of its length in a housing which is formed from two half-shells and attached to the vehicle roof, and the arcuate carrier is assigned a releasable locking device which bounds its adjustability in the closing direction of the cover.

Title: Coupling device for motor vehicles, as a transmitting and/or receiving antenna in the VHF/UHF band (preferably for the 4m band for the authorities and organisations having safety functions
Inventor: KOETTER KLAUS
IPC: H01Q1/12
Filed: 1983-09-26
Abstract: The invention relates to an RF coupling device which energises the complete motor vehicle from the interior as an antenna, without costly matching circuits or active components. As a result of fitting the coupling elements (see drawing) in a geometrically defined manner, the complete motor vehicle is excited as an antenna in the sense of a monopole or dipole group, consisting of the motor vehicle roof as the electrical reference and the struts between the motor vehicle roof and chassis. The impedance of the base point of the coupling device and the level of power coupling are governed taking into account the contraction factor of the radiating elements in accordance with the director/reflector properties of the respective bodywork. The advantages which can be achieved using the invention are, in particular, that conspicuous antenna devices on camouflaged motor vehicles are obviated and the coupling device can be integrated into normal motor vehicle accessory parts while maintaining the internal safety. <IMAGE>

Title: Method and device for testing optronic weapon systems
IPC: F42C13/02
Filed: 1983-09-28
Abstract: A method and a device for testing optronic weapon systems are to be designed for being able to reproducibly also take into consideration in the test process the effects of different dynamic situations in the beam path (20) in optronic amplitude or triangulation-type proximity fuses (3), which situations correspond to different transmission conditions and different approach speeds of the fuse (3) to a target object reflecting radiation energy. For this purpose, the receiver (5) is excited by means of a test device (10) from a stable radiation source (11), which is preferably the fuse transmitter (4) itself, via an interposed attenuation section (14); the attenuation values (22) becoming successively effective being read out of a memory (24) at variable address incrementing rate. The digitally stored attenuation values (22) correspond to signal variations (1, 2), which can be determined in a steady-state manner, in the receiver circuit (7) for different energy transmission situations in the beam path (20) between transmitter (4) and receiver (5) of the optronic proximity fuse (3). However, such signal variations (1, 2) can also be obtained by means of telemetry measures when firing trial munitions and entered into the memory (23) as sequences of attenuation values (22) to be read out, after digitisation. <IMAGE>
