Abstract: The invention relates to the long term stabilization of proteinaceous food products both for human and for animal consumption, having a moisture content exceeding 50% and preserved against microbiological spoilage by a pH value of 4.5 or below. The long term stabilization of such products is enhanced by the presence of viable homofermentative acid producing organisms, notably lactic bacteria, together with available fermentable carbohydrate. In the preferred process the pH value of a proteinaceous product is reduced to a value in the range 5.0 to 4.0 and fermentation of the bacteria is then brought about, whereby the pH value of the product attains a final value not exceeding 4.5, if necessary with a lowering of pH value by the action of the bacteria. In preferred embodiments of the process a food grade acid is added to reduce the pH of the product to the range 4.5 to 4.0 and the final pH value of the product lies in the range 4.3 to 3.8.

Abstract: A two-stage sludge process for the purification of sewage. The process is less sensitive than those of the prior art but, nevertheless, succeeds in reducing the aeration time. The sewage is supplied to a higher loaded first activation stage, the sewage treated therein undergoes an intermediate settlement accompanied by the removal of sludge in the form of return sludge and surplus sludge, the intermediately settled sewage is fed to a lower loaded activation stage compared with the first activation stage and following final settling the material therefrom is drained off in pure form, wherein all the sewage is fed to a first aerated activation stage which is operated as a maximum load stage with a space load BR of approximately 10 kg BOD5/m3/day and a sludge load BTS of at least 2 kg BOD5/kg of dry substance/day, by intermediate settling of the sewage sludge mixture removed from the first stage a strict separation of the biocenoses of the two activation stages is ensured, whereby sufficient surplus sludge is removed from the intermediate settling stage that the age of the sludge is kept low, the intermediately settled sewage being fed to a second aerated activation stage which is operated as a low load stage.

Abstract: A drivable member has an opening therethrough and is positioned within a charging port of a chamber. The drivable member has suspended therefrom an inner cover. The drivable member is axially movable with respect to the charging port between a raised position, whereat the inner cover is moved into a sealing position against an inner surface of the charging port, and a lowered position, whereat the inner cover is moved away from the inner surface. An intermediate seal is formed between the exterior of the charging port and an exterior portion of the drivable member, and the intermediate seal is maintained during all positions of movement of the drivable member. An outer cover is selectively movable into sealing engagement with an upper portion of the drivable member to form an outer seal. The outer cover may be removed and replaced by a material supply container which also forms an outer seal with the upper portion of the drivable member. Thereafter, the drivable member may be moved to the lowered position thereof to open the inner seal, and material be charged from the container through the opening and the charging port into the interior of the chamber.

Abstract: PURPOSE:To make it possible to practice economy from conventionally-two kinds of circuit to one kind of circuit, by extracting a low-frequency compoent by removing a carrier from an input signal by using a matching filter for a split-phase signal with a phase synchronous circuit. CONSTITUTION:A carrier-frequency signal applied to terminal A is integrated from the start to the end of one cycle of the carrier by matching filter 5 which regards one cycle of the carrier as a split-phase (SP) signal of one bit. At the end of the cycle, the integral value is sampled and outputted. This output has the unneeded high- frequency component removed by LPF6 and is decoded by matching filter 7 for a SP signal. Matching filters 5 and 7 mentioned above may use integral discharge type one or be composed of an A/D converter and an up-down counter. Consequently, needed two kinds of circuits can be reduced to one, so that the constitution can be simplified.

Abstract: Bristles (10), bent over at the centre, of each bristle tuft are gripped, in the bent-over region, in an elongate sleeve (11), said sleeves (11) being pushed into retaining profiles (12a). The retaining profiles (12a) each exhibit, corresponding to the outer shape of the sleeves (11), a hollow cross-section which is rounded out widely to the side in the bent-over region and is constricted to form a narrow neck part (14) in the region of the outlet cross-section. In the region of the neck part (14) of the retaining profiles (12a), the sleeve ends (13) run approximately parallel to one another and extend beyond the neck part (14) in the region of the free bristle ends. This results in a simplification in the production of the sleeve (11) and an altogether prolonged service life of the circular brush. <IMAGE>

Abstract: An identification card having an IC module for the processing of electrical signals. The IC module (9) and the leads (6) and contact surfaces (5,20) necessary for the operation of the module are attached to a separate carrier (7,17) and embedded in the identification card in such a way that the IC module is located in an area (4) of the card having the maximally permitted thickness, whereas the contact surfaces are arranged outside this area. The placement of the IC module in the elevated card area (e.g. the impressing area) allows for a thicker encapsulation of the module and correspondingly better protection against mechanical stress. On the other hand, the area of the carrier element with the contact surfaces is arranged outside the elevated area of the card, for example in the magnetic stripe area (2). As the carrier element can be designed so as to be very thin in the area of the contact surfaces, its incorporation in the area of the magnetic stripe (3) of the card presents no problems of production whatsoever. This unproblematic incorporation of the thinly designed contact surface or lead area, which is arranged on the carrier element separated from the IC module, finally allows for a very variable design of the contact surfaces, as far as their dimensions and their position on the identification card are concerned.
