Patent SE-7906971-L (SE)
IPC: H01R13/453
Filed: 1979-07-12
Abstract: An automatic locking outlet is provided for use as an electric mains wall socket. The socket comprises a front plate 1 and a slider 3, each of which has formed therein holes 9 for the passage of pins of a mains plug. The slider 3 is slidable from a first position, in which it covers the outlet holes (as shown), to a second position, in which the slider holes and outlet holes are aligned by pushing with the plug pins against the action of a spring 7. Two spring-loaded slidable locking pins 12 enter the holes in the slider 3 when in the first position to lock it in this position. When a plug is inserted, the pins thereof push the locking pins out of the hole to allow the slider 3 to be moved to its second position and the plug pins to enter the outlet holes. When no plug is inserted, there is no access to the outlet holes, thus improving the safety of the outlet. <IMAGE>

Abstract: A sewing machine (10) is provided with an electronic memory (29) for the storing of codes which determine the shape of seams. The seams are divided into portions, seam elements. By way of reflecting seam elements such as inversion of "left to right" of the needle's zig-zag positions or reverse of the feeding, it is possible to obtain several reflected images of the normal shape of the seam element. Moreover, by the invention a backward addressing in the memory is introduced, whereby the number of pattern variations essentially increases without the occupation of greater memory capacity. The backward addressing is enabled by a reversible address counter (24) to the memory, i.e. the counter can step forwards as well as backwards.

Abstract: The invention refers to a flow pilot valve comprised of a housing (1) with a flow duct (4) a valve seat set up in this (7) with a flow through (10) and in front of the valve seat in the direction of flow a valve body (12) for regulating the amount of flow, by which a compression spring (15) endeavours to keep these parts at a distance from each other. The spring force is adjusted so that the valve body (12) at varying pressure on the face side assumes varying positions in relation to the valve seat, so that the face area is reduced with increasing pressure and increases with reduced pressure in order to keep the flow amount approximately constant. The valve body (12) presents a cone like part (14) with an outer, part narrowing in the direction of flow (1)) and furthest from the seat (7) a cylindrical part (20) so that the round part (14) forming the flow-opening gap is successively reduced with increasing pressure, until the cylindrical part finally connects the flow (10). The given cone like part (14) is counted as having a ducted filling plate (13) with a transverse section against the direction of flow with one or more flow openings (16). The purpose of the invention is to further develop such a valve that will work especially smoothly and without vibration as well as for providing a more stabile flow. According to the invention, this is accomplished through that in the valve seat, with the exception of flow through (10) at least one side flow (11) is arranged with in relation to the main flow considerably less flow area, and through that this or these side areas and openings (16) in the plate of the vent body each causes a choking of the flow of mutually different effects, by which between the seat and vent body a chamber is formed (5), that checks and curbs the motion in the vent body and stabilizes the flow.<IMAGE>

Abstract: A fault location arrangement for a digital optical transmission system employing repeaters (2) has at each repeater an opto-electrical converter (55) and an electro-optical converter (5). The output of the opto-electrical converter (55) is fed via an AGC amplifier (57) and a regenerator (63) to a modulator (200) which comprises a two pole two way switch (40), a single pole two way switch (41) and two current sources (51,52). The two pole switch (40) is controlled by the regenerated data while the single pole switch (41) is controlled by a fault location signal (F2). The arrangement is such that fault information is transmitted by amplitude modulation of the digital signal but that the average power applied to the electro-optical converter (5) remains constant. Hence the amplitude modulation does not cause a varying dissipation in the converter (5) and hence reduces the possibility of variation of the wavelength emitted by the converter (5).

Date Oct. 25, 1984.The invention relates to a process for the washing of pulp with a maximum recovery of energy, the pulp after digestion being washed in a plurality of successive washing steps at a pressure above atmospheric in at least one of the steps and washing filtrate from a following step or fresh water being used as diluting and washing liquid in a given step. The outgoing washing filtrate from a washing step should be heat exchanged against incoming diluting and washing liquid to the subsequent step and a part of the filtrate (21) from the second step should be heat exchanged against washing filtrate (10) from the first step and then be combined with cooking liquor (23) for the digestion of the pulp. As diluting and washing liquids in the last two steps (4, 5), fresh water is used, which has also been heat exchanged against outgoing washing filtrate (54, 10) from the last and the first washing step. The gases leaving the washing steps are heat exchanged (25, 36, 47) against fresh water, which is then used as the diluting and washing liquid in the last step, the gases (11) from the first step however being heat exchanged against cooking liquor (8) for the digestion process. The condensates (13, 27) obtained from the heat exchange of the gases in each step are combined with the diluting liquid to the following step except for the steps in which fresh water is used as the diluting liquid. The resulting uncondensable gas fractions after the heat exchange are combined (59) and are finally heat exchanged once more (60) against incoming fresh water (57). The pulp (6) obtained from the digestion process is also (7) heat exchanged against the cooking liquor (8) which is led to the digestion process.
