Abstract: Drying felts have since many years been provided with a seam (2) in order to facilitate the mounting in the paper machine and during the last three years also the press felts have been provided with such a seam. In order to prevent that the paper web is marked by the seam, the seam is covered by a wadding flap, which is a continuation of the wadding layer which is fastened to the felt. The wadding flap is worn in different ways when the felt is used in the paper machine and its firm­ness will therefore decide the limit for the effective life­time of the felt and marking in the web will occur due to the wearing of the wadding flap. In order to decrease the wear on it, so that a better felt is obtained and also a safer production of paper, the protective flap includes at least one layer (6), the fibers, the yarns or filaments of which are mainly placed in the moving direction of the felt in the machine.

Abstract: A memory system for storing and retrieving data sequences of symbols in response to a query sequence is disclosed. Each of the sequences is made up of three types of symbols, constants, delimiters, and variables. A data sequence is retrieved in response to a query sequence if the two sequence can be made identical by replacing the variables in each sequence by constants or combinations of constants and delimiters, the combinations beginning and ending with a delimiter. To reduce the time needed to search the memory for all data sequences corresponding to a given query sequence, multiple processing units are employed. In addition to carrying out rule-based searches, the memory system can efficiently retrieve all records containing a specified list of key words.

Abstract: A gas generator chemically generates a gas from a chemical reaction between two reagents (Ra,RB) contained within a common container. The reagents are normally separated by a gas generation chamber (Gb) into different regions of the container in the absence of gas generation therein. A reference pressure source (GA) of a predetermined pressure forces the two reagents into contact with each other when the pressure of gas in the gas generation chamber is less than the predetermined pressure. A valve (V) in fluid communication with the gas generation chamber (GB) is provided to withdraw the generated gas from the chamber when OPEN. As the gas flows through the valve from the chamber the gas pressure in the chamber drops permitting more mixing of the reagents. When the chamber pressure becomes equal to or higher than the predetermined pressure applied by the reference pressure source, the reagents become separated again and gas generation ceases.

Date Oct. 20, 1988.A reprographic apparatus has a copyboard for holding a document to be exposed in a flat position in an exposure plane. The copyboard includes a support plate defining the exposure plane with transparent plate arranged above the plate and being pivotally connected therewith along one side edge. A releasable hold-down mechanism locks the glass plate in an operative position in which it holds the document in pressurized contact with the support plate. A movable pressure bar extends in parallel to the pivotally connected side edge of a glass plate, the bar being connected at its ends with side plates, which are displaceably and pivotally connected to a housing of the copyboard. Such an apparatus is known for instance from the EP 0 085 862. After a document has been placed in the exposure plane between the two plates of the reprographic apparatus, a hold-down mechanism (or lock) presses the transparent plate against the document on the support plate, and air still present between the two plates can be extracted by suction in order to achieve a flat exposure position of the document. The lock is provided with an extension to overcome spring forces when unloading an original. A disadvantage of the described system is that it can only handle documents with a size smaller than that of the transparent plate as, otherwise, the hold-down mechanism would damage or destruct the document.

Abstract: A process for producing a high purity oleic acid composition utilizing enzymatic hydrolysis is disclosed. The process involves obtaining high oleic sunflower seed oil which oil contains triglycerides having fatty acid moieties of oleic acid in an amount of 60 % or more, preferably 80 % or more and further wherein the ratio of linoleic moiety to oleic moiety is less than about 0.25, preferably less than about 0.09. The oil obtained from the high oleic sunflower seed oils is subjected to enzymatic hydrolysis by contacting the oil with hydrolase enzymes and/or various combinations of hydrolase enzymes within an aqueous medium at a temperature in the range of 20-60 DEG C and a pH in the range of about 4.5 to about 10. The oil, hydrolase enzyme and water are agitated so that hydrolysis occurs at the oil water interface and the acid moieties of the triglycerides are separated away. An oleic acid layer is allowed to form and separate away from the aqueous medium and the aqueous medium is then separated away to provide a highly pure oleic acid composition.

Abstract: The armature of a building inlet consists of a protective pipe (1) made of metal which is held in the building wall and of a metallic inner pipe (6), guided in the said protective pipe, having a terminal skirt-type piston (8). Connected to the free end of the inner pipe (6) is the underground medium pipe. The skirt-type piston (8) contains in the cylinder wall a transverse bore (9) which, in the starting position (open position) coincides with a wall bore (10) in the protective pipe (1), to which the building pipe can be connected. An outwardly projecting piston rod (13) with a marking (17) for position indication emerges from the head end of the skirt-type piston (8). In the event of a pulling or pushing action on the underground supply pipe, the inflow of medium is automatically cut off by displacement of the skirt-type piston (8). The particular operating condition of the armature can be detected from inside the building by visually checking the position of the piston rod (13). In the event of a response in which the medium has not yet been shut off, it is thus possible to introduce suitable countermeasures in good time. <IMAGE>
