Abstract: 1. A soldering tool with temperature regulation wherein the heating element (1) of the soldering tool is fed with a.c. current via an electronic switch device (6) which is switched on and off via a control circuit (4) in dependence on the output signal of a first temperature sensor (2) arranged on the heating element (1) and which has protection devices for protection against a thermal and/or electrical overload of the workpieces to be soldered, wherein the control circuit (4) includes a comparator (8) for comparing the output signal of the temperature sensor (2) with a desired value signal (11) and wherein a second temperature sensor (3) is arranged in the spatial vicinity of the first temperature sensor (2), characterized in that, the output signal of the second temperature sensor (3) is passed together with a second desired value signal (12) representing a limiting temperature to the inputs of a comparator (9) of a second control circuit (5) the output of which is connected to a further switch device (7) inserted in the energizing circuit of a relay (10) which, in the made operating condition, permits the energization of the heating element.

Abstract: pneumatic force multiplying device for use in an hydraulic brake system of a motor vehicle. The device comprises a housing defined by a front shell (2) and a rear shell (3). a valve body (4) slidably supported by the rear shell and incorporating therein a valve mechanism (10), a flexible diaphragm (9) connected to the circumference of the valve body and extending in the radial direction toward the outer circumference of the housing to divide the interior of the housing into a front chamber (A) and a rear chamber (B), and a piston plate (7) mounted around the valve body and extending contiguous to the diaphragm. A problem with a known device is that the front and rear shells deflect appart under the influence of the multiplying force. 
     In order to overcome this problem the pneumatic force multiplying device of the invention is provided with a rigid connecting rod (17) which extends through both chambers and the opposite ends of the connecting rod are rigidly secured to the two shell portions.

Abstract: Procede de preparation d'un film isolant pour surface semi-conductrice, dans lequel un substrat de silicium est soumis a une nitruration directe pour preparer un film de nitrure de silicium. Le substrat de silicium est premierement soumis a un traitement de nitruration a chaud pour produire un film relativement epais de nitrure de silicium. Le substrat de silicium est alors soumis a un traitement de nitruration dans de l'ammoniaque ou dans une atmosphere de gaz contenant de l'ammoniac gazeux, afin de produire un film dense et relativement epais de nitrure de silicium. Le film resultant de nitrure de silicium est utile en tant que film isolant pour des dispositifs semi-conducteurs et aussi en tant que masque pour la diffusion d'impuretes ou l'oxydation selective dans la fabrication de dispositifs semi-conducteurs.

Abstract: Pour le refroidissement d'elements semi-conducteurs de puissance, tels que des redresseurs de courant, au moyen d'un circuit de fluide de refroidissement et d'un echangeur de chaleur ventile de maniere forcee, l'eau et l'huile sont generalement utilises comme fluide de refroidissement primaire. Ces fluides presentent toutefois des inconvenients, en particulier une faible capacite d'isolation avec, pour l'eau, une souillure pratiquement non evitable et une reduction du pouvoir isolant sur les conducteurs en dehors des fluides de refroidissement par suite d'accumulation de poussiere dans les points de fuite de l'huile. D'autres fluides, qui sont en eux-memes plus appropries, necessiteraient un agrandissement non economique de l'echangeur. Afin d'eviter ces inconvenients, on utilise un circuit de fluide de refroidissement secondaire avec un evaporateur (6) par lequel on fait passer le circuit primaire qui passe par l'echangeur ventile de maniere forcee (3). Ainsi une partie de la chaleur est dissipee par l'echangeur et le reste par l'evaporateur et le circuit secondaire, ce qui evite un agrandissement de l'echangeur lors de l'utilisation d'un fluide de refroidissement primaire particulierement approprie tel qu'un liquide du type inerte. De maniere appropriee, le condensateur (11) du circuit secondaire est relie a l'echangeur (3).

Abstract: An impending kickback condition in the operation of a power tool or machine tool system is sensed and used to control or eliminate the kickback. The ability to sense an impending kickback condition can be used in all categories of power driven tools. The change in force applied to the power driven tool or other implement is monitored with a microcomputer by measuring the rate of change of current. If the current is increasing, the microcomputer compares the rate of change of current with a threshold value which may be either preset or.computed by the microcomputer. If this threshold value is exceeded, an outputcontrol signal is generated by the microcomputer which inhibits the coupling of power to the tool or other implement and/or applies a brake to stop the tool or implement. In orderfor power to once again be coupled to the tool or implement, the start switch must be opened and then reclosed or some other signal provided by the operator or another predetermined condition must be fulfilled.

Abstract: In a method for the production of thermally insulated composite sections a free space (4) formed between at least two metal sections (1,2), held spaced apart, and sealed at the bottom is filled from its open side with an insulating material (10) which at first is in liquid form and then hardens. In order to produce such sections, particularly also those of large size, with the least possible expense for labor and material, and at the same time to achieve the most favorable heat insulation values in the insulating region, solid insulating material layers (12,13) positively and frictionally joining together the metal sections (1,2), and insulating layers (14) hardening with a porous structure are introduced in succession into the free space (4), each layer only partly filling the free space. The introduction of the solid insulating material layers (12,13) and of the insulating layers (14) is expediently effected with the aid of a plurality of inlet nozzles (16, 17, 18) whose actions are chronologically staggered and which are disposed one behind the other in the working direction (19) of the filling operation, and for the porous insulating layers (14) the same material can be used as for the solid insulating material layers (12,13), a blowing agent which provides the porous insulating layers (14) with their porous structure being contained in the material in the case of the porous insulating layers (14).

Abstract: The photolysis of water is accomplished in a light illuminated aqueous system using a photosensitizer, such as a manganese porphyrin, in conjunction with an electron acceptor, such as methyl viologen. In the photolysis process, oxygen is produced in an active form whereby it is scavenged from the reactant solution by a trapping agent to yield an organic oxide product. Hydrogen may also be produced from the photolysed water in a compatible reaction with the electron acceptor, and the photosensitizer and the viologen electron acceptor be recycled in the process.

Abstract: In an AC circuit a unipolar transient surge suppressor is shunted across a sensitive load, and a plurality of steering or rectifier diodes are so arranged in the circuit that, by their switching action, all transient energy that appears on the sinusoidal wave or waves of other shape of the AC circuit is guided to the unipolar transient surge suppressor such that the polarity of the voltage is applied in the proper direction. Thus transient surges occuring on either the positive or negative half-wave are properly directed through and dissipated by the unipolar suppressor.

Abstract: Improvements in conventional ring spinning processes of the type wherein a strand of staple fibers if drafted, twisted and collected on a ring spinning frame are obtained by the added step of subjecting the strand to the twisting action of a pneumatic false twister between the drafting and collecting steps. The added step improves performance and/or permits the process to be operated at higher front roll delivery speeds for any given spindle speed without sacrificing performance. The higher delivery speeds results in improvements in the productivity of the process and the apparent value of staple yarn produced thereby.
