Abstract: A filtering apparatus (10) for cleaning plastics melts on a high-pressure press comprises a housing (11) with a throughflow bore (12) and a plate (13) which can rotate in the housing (11) and has a plurality of openings (14), in each of which screening plates (15) are arranged. The throughflow bore (12) forms part of the flow channel of a high-pressure press. One opening (14) always lies outside the area of the throughflow bore (12), but still completely inside the housing (11). Arranged on the side lying behind the plate (13), seen in the direction of flow of the plastics melt, there is inside the housing (11) a purging channel (16), which can be released or shut off, according to choice, by means of a shut-off device (shut-off bolt 17). This purging channel (16) opens out into a preferably slit-like purging nozzle (18), which lies in the area run through by the opening (14) lying constantly outside the throughflow bore (12). On the side of the plate (13) opposite the purging nozzle (18), the housing (11) is provided with an outlet channel (19). 
<??>If the purging channel (16) is released, a counterpressure purging, and consequently cleaning, of the screening plate (15) takes place, so that the intervals between times when it becomes necessary to change clogged screening plates (15) can be considerably increased.

Abstract: An image processing system, comprising: a camera for taking a picture image of an object and producing a corresponding picture image signal; a binary discrimination circuit for converting the picture image signal into a binary signal; a memory unit for storing the binary signal; and feature extracting circuit for extracting a geometric feature of the picture image by processing the binary signal. Preferably, the feature extracting circuit comprises: an edge detection circuit having a hardware structure; and an arithmetic processing unit for computing, through a software process, geometric features from a graphic image included in the picture image of the object according to data on edge addresses. Thus, the processing speed is increased and the size and cost of the system is reduced by carrying out edge detection and address data collection requiring a large amount of processing work by means of a dedicated hardware circuit and carrying out arithmetic and other processes by means of software. Further, since the software of its arithmetic unit can be easily modified, the versatility of the processing work can be improved, and the range of application of the system can be broadened.

Abstract: A picture signal (Y) is applied to a segmentation device (2) where it is subjected to a segmentation algorithm to identify regions of similar intensity. The resulting region signal is applied to a modal filter (9) in which region edges are straightened and then to an adaptive contour smoothing circuit (10) in which contour sections identified as representing false edges are filtered. The filtered signal is subtracted from the original luminance signal in a subtractor (12) to produce a luminance texture signal which is encoded by a texture encoder (17). The region signal is encoded in a region encoder (24) together with flags indicating which of the contours in the region signal represent false edges.

Abstract: A process and an apparatus for producing a substantially oxygen-free gas from air are disclosed. The process involves reducing the oxygen content of air in a first step (e.g. in apparatus 10) to 0.5% or more by volume by a non-cryogenic physical separation technique, e.g. by means of the use of a molecular sieve or a diffusion membrane designed to separate oxygen from nitrogen. In a second steps (e.g. in chamber 12) the oxygen remaining in the resulting oxygen-reduced gas is substantially eliminated by contacting the oxygen-reduced gas with an oxidizable material that reacts readily with the oxygen (under suitable conditions) without introducing oxidizing materials or pollutants into the gas. The preferred oxidizable material is a porous bed (21) of carbon particles heated to a temperature of 700-900°C or methane as a gaseous fuel. These materials introduce carbon monoxide and (in the case of methane) water vapour into the substantially oxygen-free gas. Carbon monoxide is an acceptable non-oxidizable gas for many purposes and, if necessary, the water vapour can be removed by condensation. The process can produce an inexpensive gas mixture containing less than about 0.1% by volume of oxygen which is suitable for many industrial purposes, e.g. as the heat transfer medium for a contained arc plasma torch (41) used for heating materials (44) containing aluminum or aluminum alloys.

Certain of the oxazolidinones of the formula II are novel and are provided as a further feature of the invention. The invention also provides a novel process for the production of the pharmaceutically-useful 5-amino-4-hydroxyvaleric acid derivatives of formula VI.

Abstract: This invention implements a cache access system that shortens the address generation machine cycle of a digital computer, while simultaneously avoiding the synonym problem of logical addressing. The invention is based on the concept of predicting what the real address used in the cache memory will be, independent of the generation of the logical address. The prediction involves recalling the last real address used to access the cache memory for a particular instruction, and then using that real address to access the cache memory. Incorrect guesses are corrected and kept to a minimum through monitoring the history of instructions and real addresses called for in the computer. This allows the cache memory to retrieve the information faster than waiting for the virtual address to be generated and then translating the virtual address into a real address. The address generation machine cycle is faster because the delays associated with the adder of the virtual address generation means and the translation buffer are bypassed.
