Filed: 1992-03-18
Abstract: This invention relates to interfaces between facsimile machines and cellular telephone systems (including both cellular subscriber terminals and the fixed part of the system, such as the mobile switching center and the interworking function). The cellular radio telephone system could for example be GSM. To prevent two different facsimile machine timers (specified in the CCITT T.30 recommendation) from expiring during the communication between two such machines connected to the GSM environment, a timer reset command (e.g. a command repeat signal) is automatically sent by the interface (12 or 15) to the facsimile machine on receipt of the command from the facsimile machine, for causing the machine to repeat its command so as to allow time for receipt of a response from the other machine. Instead of sending this response only if a command is not recognized (as recommended in T.30), it is used as the default response whenever the GSM environment receives a command from a facsimile machine. If necessary this response can be used twice.

Abstract: The present invention relates to a method of making paper from bleached or alkaline treated pulp by dewatering pulp containing bleached or alkaline treated vegetable fibers from wood or non-wood species. It was found that such bleached or alkaline treated pulps contain a substantial amount of harmful pectins. By incorporating pectinase in the bleached or alkaline treated pulp such harmful pectins in the aqueous phase of the pulp are degraded and thus rendered harmless to papermaking processes.

Abstract: 1,071,571. Semi-conductor devices. RADIO CORPORATION OF AMERICA. May 19, 1964 [May 28, 1963], No. 20655/64. Heading H1K. [Also in Divisions H3 and H4] A switching circuit {see Division H3) utilizes a planar insulated-gate field-effect transistor. As shown, the body 12 may be of polycrystaliine or very lightly doped P-type silicon of 100 ohm cm. and is coated with heavily-doped N-type silicon dioxide. Part of the silicon dioxide is removed by a photo-resist and etching technique, where the gate electrode G is to be formed and around the outer edges. The body 12 is then heated in water vapour so as to grow silicon dioxide layers on the exposed silicon areas and to diffuse impurities from the silicon dioxide layer to form source and drain regions S, D. The deposited silicon dioxide is then removed over part of the source and drain regions and electrodes 16, 22, 24 are deposited by successive evaporation of chromium and gold to form the source, gate and drain electrodes. The gate electrode 22 is insulated from the body by a layer of silicon dioxide which overlies an inversion channel C of controllable conductivity connecting the source and drain regions. The device may alternatively be formed on an N-type substrate. The device exhibits linear bi-directional drain current/voltage characteristics (Fig. 3, not shown) and may be arranged so that the drain current may be cut off by a zero gate voltage or, if the device is baked in oxygen, a finite voltage will be necessary to cut off the drain current.

Filed: 1987-06-24
Abstract: The vertically ascending casting of a thin-walled metal pipe and integral end fitting from a bath of molten metal is implemented using a housing 12 and a core 14 to mold the end fitting or bell housing and a tubular draw tube 6 to mold the pipe shank. The end fitting E is first formed by forcing the metal to rise in the annular space 16 between the housing and the core, simultaneously forming the initial section of the pipe shank. Once the end fitting has solidified it is extracted upwardly, step by step, while shank sections are simultaneously withdrawn from the metal bath. These sections are also solidified step by step along a tapering front S in the bath until the desired length of pipe T has been obtained.

Abstract: In a continuous vertical ascending casting installation for iron pipes T, graphite elements 3 defining a molten metal feed chimney 28, a die and coaxial core arrangement 13, 14 and an expansion vessel 16 are mounted under a cover 2 of an electric furnace 1. In use these graphite elements are immersed in a bath of molten metal contained in the hearth area 7 of the furnace, to thus enable precise temperature regulation and control. The outer surface of the die 13 is surrounded by a water cooling jacket 18, and the level of molten iron in the hollow cavity 25 of the core 14 is varied by the expansion vessel 16, to provide even finer control of the temperature gradient within the annular casting space. The overall arrangement is thus similar to a double boiler.

Abstract: Method of manufacturing a seam connection between body flanges (5) and end wall flanges (9) of a drum (11) by means of a seaming roller (14) which folds the flanges about each other, the essential difference with respect to prior art seaming operations being that the precurl (6) of the end wall flange (5), known in itself, is guided into the lower portion of the groove (15) of the seaming roller so that during the radial movement inwardly of the seaming roller (14) the flanges (5,9) may bulge outwardly in axial direction and form a so called cat's back by means of which the flanges and accordingly end wall (2) and body (1) are centered upon each other, whilst further in circumferential direction a distance is provided between the upstanding edge (3) of the end wall (2) and the curvature (10) between body (1) and body flange (9) which distance during the seaming operation may be reduced. It moreover is possible by using a support (13) for the end wall which is smaller in diameter than the diameter of the body (1), to perform the seaming operation inwardly to a degree such that the final seam has an outer diameter which is substantially equal to the diameter of the body (1).
