Title: Apparatus for applying colour in an image reproduction machine
Inventor: IKUTA KUNIO
IPC: H04N1/46
Filed: 1981-03-31
Abstract: An apparatus for applying colour in an image reproduction machine is described in which a pick-up head scans the original image and thus produces an image signal. This is fed to a colour discriminator which discriminates the colour tone of the image signal and delivers a discrimination signal to a control device for the half-tone point area ratio. The control device delivers a signal which corresponds to a particular half-tone point area ratio of the half-tone point to be recorded. This is done for each colour. An illumination control device to which this signal is fed varies the brightness in accordance with the half-tone point area ratio depending on the output signal of the first-named control device. An illumination head scans a recording film and records on it a reproduction image synchronously with the pick-up head in accordance with the half-tone point area ratio. This apparatus can be operated accurately and rapidly without special skill.

Title: Method for linearising the characteristic of a valve, and a valve for carrying out the method
Inventor: KRAUSS RUDOLF
IPC: F02M51/06
Filed: 1981-11-28
Abstract: A method for linearising the characteristic of a valve, and a valve for carrying out the method are proposed. The valve comprises a valve housing (50) with a nozzle support (51) on which a nozzle body (37) is mounted. A valve part (35), which can be operated electromagnetically and is guided in the valve housing (50), interacts with a valve seat (36) constructed in the nozzle body (37). Fluid is supplied under pressure to the valve (1), via a fuel supply line (17), which fluid can flow out under pressure, as a function of the opening duration of the valve, when the valve part (35) is lifted off the valve seat (36), via swirl ducts (36) and a preparation hole (40). In order to linearise the characteristic of the valve (1), preferably in the case of small controlled flow rates, an elastic damping element (54) is arranged close to the valve seat (36), which damping element damps pressure fluctuations when the valve is opened, in an axially fixed manner, and hence results in a linearisation of the characteristic. <IMAGE>

Title: Ignition system for an internal-combustion engine
Inventor: EUGEN KIELBAS
IPC: F02P3/04
Filed: 1981-12-12
Abstract: An ignition system is proposed, which is used for igniting the compressed fuel-air mixture in a cylinder of an internal-combustion engine. In this ignition system, the primary winding (5) of an ignition coil (6) is connected in series with an electronic interruptor (7). Current is passed via the primary winding (5) as soon as a threshold switch (15) is in a switched-on state. The threshold switch (15) can be controlled by an upstream AC generator (27). From the AC voltage signal (Uc) of the AC generator (27), the curve section (Ue) preceding the peak value (Ud) is used to switch on the threshold switch (15), and the curve section (Uf) following the peak value (Ud) is used to switch off the threshold switch. The switching-on value (Ua) and the switching-off value (Ub) are preset to the same polarity with respect to the zero value (0) of the AC voltage signal (Uc), to be precise with the object that, when the ignition system is switched on but the internal-combustion engine is not in use, the interruptor (7) cannot pass current via the primary winding (5). According to the invention, when the internal-combustion engine is taken into use, a resistance branch (31) is temporarily caused to influence the threshold switch (15) in the sense that at least the switching-off value (Ub) of the threshold switch (15) changes in comparison with the presetting of its polarity with respect to the zero value (0) of the AC voltage signal (Uc) in order to ensure that, when the internal-combustion engine is taken into use, the ignition point corresponds at least virtually in time with the top dead centre position of the piston. <IMAGE>

Title: Apparatus for cleaning animals, especially pigs
Inventor: WESSJOHANN HUBERT
IPC: A01K13/00
Filed: 1981-12-19
Abstract: The invention relates to an apparatus for cleaning animals, especially pigs, having water nozzles arranged at the side of a cleaning box. In the cleaning boxes known hitherto, much water has been consumed by a large number of water nozzles, and only a relatively poor cleaning effect has been achieved owing to the fixed installation of the water nozzles. The object of the invention is to provide an apparatus for cleaning animals, especially pigs, which makes it possible to achieve a good cleaning effect with low water consumption. This object has been achieved, according to the invention, in that the water nozzles are arranged to be pivotable about a horizontal axis. Animals can thus be cleaned in a simple manner, a good cleaning action being achieved as a result of the pivotability of the water nozzles, since the water jets do not impact on the animals only from a single direction. In addition, the range of action of the water nozzles is increased, so that water nozzles can be saved.

Inventor: PHILLIPS ROGER
IPC: C08J7/06
Filed: 1982-04-02
Abstract: Flexible polymer packaging films having thin films of inorganic coatings deposited thereon to reduce the vapor permeability of the article. Inorganic thin film coatings comprising a composite of two materials are disclosed to confer both substantial transparency and retortability on the overall packaging film structure. The two material film composite involves either sequentially deposited films with the first thin film layer serving as an adhesion layer and the second thin film layer serving as a barrier layer. Alternatively, the two materials may be co-deposited to form a single thin film layer which provides sufficient adhesion to confer retortability on the overall film structure and also functions as relatively impermeable gas and vapor barrier for reducing the vapor transmission rate through the product. Various coated single film articles and dual film laminated articles are disclosed.

Title: Differential heat engine
Inventor: KNOTT FRANZ JOSEF
IPC: F03G7/04
Filed: 1982-11-03
Abstract: The special feature of this stroke piston engine is that the superpressure or reduced pressure in the cylinder chambers is generated via the heating or cooling, respectively, of the gases via the cylinder walls. Since no combustion is involved, the temperature changes take place more slowly and, correspondingly, the design features of the engine are also characteristic:   a) series arrangement of cylinders (pistons), no valves, slots, connecting rods and crankshaft, so that a closed working process and one-stroke process are possible. b) Relatively small temperature differences between the cylinders, and slow expansion or impansion of the gases in the cylinders, require high-pressure loading, holding top dead centre, sealing top dead centre and piston pressure equalisers. Thus, for example, the engineering problems of the engine mainly concern, because of the high-pressure loading and holding of top dead centre, the sealing and take-off of the mechanical energy, while the advantages are predominantly to be found in the usability of heat energy at relatively low temperature or temperature difference, and absence of exhaust gas. The internal conversion of the stroke motions into electrical pulses with simultaneous parallel arrangement of a plurality of units to give a battery made it possible to generate current by combustion of low-grade fuels as well as from waste heat and solar energy. o

Patent DE-3307852-A1 (DE)
Title: Flexible valve timing for four-stroke engines to achieve timing appropriate to the engine speed. Timing appropriate to the engine speed is understood to mean that the inlet and exhaust timing and the overlap of the inlet and exhaust timing is ideal as regards optimum charging and combustion space scavenging for all engine speed ranges
Inventor: HUBER MARTIN
IPC: F01L13/00
Filed: 1983-03-05
Abstract: The invention concerns the adjustment of the valve timing of a four-stroke engine as a function of the engine speed. In plan view, the bucket tappets have a trapezoidal facing, i.e. widen in one direction. As the speed of the engine increases, a centrifugal device pulls the cam shaft further and further towards the widening facing of the bucket tappet. As a result, the cams press the bucket tappet downwards for an increasingly long time and guarantee optimum charging and scavenging of residual gas for all engine speeds.
