Patent SE-7903955-L (SE)
Inventor: MATTSSON B
IPC: B22F3/15
Filed: 1979-05-07
Abstract: For manufacturing an article of a ceramic or metallic material by sintering and simultaneous isostatic pressing of a powder of the material, the powder is enclosed in an embedding material of glass which is made impermeable to gas before the isostatic pressing is carried out with a gaseous pressure medium. The powder is introduced into the mould cavity of a mould 10 made of glass powder, the mould cavity having a shape corresponding to that of the article to be manufactured, whereafter the mould is covered with glass 14 which, together with the mould, forms an embedding material for the powder. The powder and the embedding material are then located in a vessel 15, and the embedding material is transformed into a melt having a surface limited by the walls of the vessel, below which surface the powder in the mould cavity is located, before the pressure necessary for the isostatic pressing is applied to the melt with the gaseous pressure medium. Alternatively the tube through which the mould cavity is filled may be covered with a plate of glass rather than using the covering of glass 14. <IMAGE>

Abstract: The arrangement comprises a water removal opening with associated water removal pipe 4 and a plate element 6 which is arranged at the opening, above the roof plane 1, and is larger than the opening, so that the arrangement provides a closed flow of water as the water passes under the plate element towards the opening in the vertical water removal pipe. The plate element is dimensioned such that the minimum length of its edge and the maximum distance hc of the plate from the roof plane 1 correspond to the amount of water which, according to limits set for open flow, forms an overflow height corresponding to this distance for an opening with the edge length in question. For promoting the heat transfer from the inside of the building, the vertical water removal pipe is secured at the upper end in a trough 5 which is sunk into the roof structure and which is larger than the opening, and the diameter of the upper edge of the trough is designed to correspond substantially to the minimum width of the plate element. <IMAGE>

Abstract: The invention relates to an arrangement for identifying traffic in paired cables. The different layers of traffic are distinguished by different levels and frequency ranges. The arrangement comprises a limiter which is connected to the paired cable and transmits an output signal with essentially constant amplitude and a frequency which corresponds to the strongest frequency component of the input signal. The limiter can be constructed from inverters connected to an amplifier or from an amplifier with a Schmitt trigger. The limiter is connected to a frequency indicator which indicates within which frequency range the strongest frequency component lies. The frequency indicator can consist of monostable rockers or a counter and a decoder. The decoder interprets the output signal of the counter and can be constructed from a fixed gate network or a programmable memory. The output signal of the frequency indicator is connected to an indicator which indicates the frequency range concerned, for example by means of flashing light- emitting diodes. <IMAGE>

Abstract: An overvoltage and overcurrent protection for an exchange terminaL circuit which has two input terminals (a, b) and a number of output terminals (T1-T). The input terminals are connected to a two-wire line and the output terminals are connected to equipment for the transmission of analog as well as digital signals over the line via the exchange terminal circuit. The exchange terminal circuit comprises an impedance matching network having a transformer at the primary as well as secondary sides of which there are networks that are symmetric in respect to earth. The network at the primary side comprises two primary winding halves (L1, L2) between which a capacitor (C) is series connected. The novel features of the invention is a varistor (V1) that is connected in parallel with the capacitor (C). When a surge pulse has charged the capacitor to the rated voltage of the varistor the varistor goes conductive thereby increasing the current through the primary winding until the core of the transformer is saturated. At the secondary side of the transformer there is a varistor (V2) and Zener diodes (Z5-Z8) which act to stepwise reduce the surge pulse as transformed to the secondary to a voltage which is safe for the connected equipment. <IMAGE>

Abstract: It is generally difficult to engage a flexible press roll jacket 2 on a circular end wall 3 of a press roll since the flexible jacket 2 tends to assume a shape which is other than cylindrical. This difficulty is overcome by using an auxiliary instrument 1 which has an elongate recess 13 for receiving an elongate section of an edge zone of the jacket 2. The instrument is curved so that it supports the edge section of the jacket essentially on a radius R10 which corresponds to the circular end wall periphery. The instrument has at least one grip section 17 intended to be gripped by a hand. The recess 13 is preferably designed to receive the edge section of the jacket with a light press fit, and one or more screws 21 can be arranged to clamp a section of the edge zone of the jacket securely against a radially internal wall 11 in the recess 13. The instrument can be made up of flat sheets 19, 20 of steel, and the radially outer side wall 16 of the recess 13 can consist of a plurality of flat fingers 14 evenly distributed in the circumferential direction and extending sidewards. <IMAGE>
