Title: Method and arrangement for information transmission via the low-voltage electrical power distribution network, and its use
Inventor: JAQUET CLAUDE-ERIC
IPC: H04M19/04
Filed: 1984-02-08
Abstract: In order to transmit the telephone bell information via the low-voltage 220V electrical power distribution network, a fixed-frequency signal is generated with the aid of an emitter (3) when the telephone bell is activated, which signal is applied to the power distribution network through a plug (5). One or more receivers (7, 11) connected up to the same phase of the mains, emit a sound when they detect the emitted frequency. This device thus makes it possible to obtain a movable and cheap receiver which can be connected up to any mains socket of a house and is capable of restoring the telephone bell information. <IMAGE>

Abstract: A tensioning device has a worm gear mounted in a hollow section enabling the longitudinal displacement of a lift member with respect to a hollow section. The hollow section base and the lift member in each case carry a joint bolt, which cooperates with joint heads fixed to the adjustment means. The worm gear permits a very sensitive and exact setting of the spacing between the two joint bolts, which remains unchanged over a long period. In addition, the tensioning device is particularly suitable for orthopedic purposes, due to its small constructional volume.

Abstract: A self-emulsifiable resin powder can be dispersed in water without utilizing additional surfactants or expending large amounts of mechanical energy. Such self-emulsifiable resin powders offer numerous distinct advantages over conventional latices. One of the most important benefits that is realized by utilizing self-emulsifiable resin powders is that they can be shipped dry which is the equivalent to shipping a latex with a 100 percent solids content. In other words, such self-emulsifiable resin powders eliminate the necessity for shipping water in latices. The self-emulsifiable resin powders disclosed herein also have the advantage of having low carboxyl contents and of being dispersible into aqueous systems which contain virtually no surfactants. These self-emulsifiable resins contain a relatively small proportion of repeat units which are derived from both acrylic acid and methacrylic acid. The self-emulsifiable resin powder compositions disclosed herein also contain a small amount of a metal salt of an alkyl sulfonate or a metal salt of an alkyl sulfate.

Abstract: The aim is to produce a dental drill with a shaft which can be rotated about an axis and which has, at a front shaft part, a first drill element with cutting edges arranged at a radial distance from the axis, and which, during preparation of the tooth, prevents an excessively deep milling and can be guided accurately and, particularly in the case of a channel preparation, ensures that no excessively deep channels can be made in the tooth. For this purpose, it is proposed that there be arranged, on a side of the first drill element lying opposite the shaft, a bearing surface which is free of cutting edges and is rotationally symmetrical to the axis, and whose greatest radial extent is smaller than that of the drill element. <IMAGE>

Abstract: This invention is concerned with materials for nonlinear optical devices for the conversion of optical energy at one frequency to optical energy at another frequency. 
     Laser techniques have been developed so that it is possible to obtain a limited number of fundamental frequencies of coherent laser light by utilizing solid, gas, and liquid media. However, in many applications, laser light having frequencies not among the fundamental frequencies obtainable is required, and in some cases laser light exhibiting a continuous spectrum over a certain range of frequencies is required. 
     Inorganic materials have been used extensively for nonlinear optical applications. However, they are only of limited use because of their bandwidth limitations. 
     The possibility of using organic materials in nonlinear optical devices has generated much interest recently because a large number of organic materials are available for investigation and because they do not have the bandwidth limitations of inorganic materials. 
     This invention provides devices comprising a laser source of coherent light radiation at a fixed fundamental frequency, a crystalline N,Nʹ-substituted barbituric acid that crystallizes in a non-centrosymmetric configuration, means for directing the output radiation of the laser onto the N,Nʹ-substituted barbituric acid, and output means for utilizing the second harmonic frequency.

Abstract: The invention relates to an arrangement for advancing a continuous strip of mutually integrated nails to the nail driving section (5) of a nail driving apparatus provided with a safety-catch device (24) and a nail strip magazine, and to hold the nail strip in the nail driving section. Single nails are stripped from the nail strip in the nail driving section by means of percussion and driven, in con­junction therewith, into the workpiece to be nailed. The magazine (6) incorporates a nail strip accommodating strip guide path (7) which adjoins the nail driving section (5) and in which the nail strip is held biassed towards a nail driving location in the nail driving section (5) by strip feed means (17, 18) located adjacent the strip guide path and engaging the nail strip located therein. The nail driving location is constructed in a manner to prevent a lone, unattached nail from twisting or turning therein. For the purpose of positioning the foremost nail in the nail strip in an exact position in the nail driving loca­tion (this foremost nail being the next in line for sepa­ration/driving into the workpiece) there is provided a rotatable nail positioning element (35) which is journal­led for rotation and sideways movement in the nail driving section (5) and which is capable of being brought into engagement with the nail strip. The safety-catch device (24) is movable relative to the nail driving section and is held in a forward safety position by means of a coil spring. The safety device presents a latching surface (31) in the region of the positioning element (35), and arran­ged between the latching surface and the nail positioning element is a movable latching element (38). As the safety-­catch device (24) is retracted (to its nail firing mode)   the latching surface (31) is urged against the spherical latching element (38), which in turn moves the nail posi­tioning element (35) into position-fixing latching engage­ment with the nail strip, in a region thereof immediately behind the foremost nail located in the nail driving loca­tion.
