Abstract: An electrohydraulic rotary brake comprises an inner core, at least one energizing winding, a cylindrical amagnetic insert and an annular part outside the core and the insert. A cylindrical bore is excentric with respect to the cylindrical peripheral surface of the insert, recesses being provided with magnetizable sliding vanes and a brake fluid. On a rotary shaft, are mounted lateral flanges in fluid-tight manner, the inner core being fast to the rotary shaft and to the insert, all three being arranged so as to constitute a rotor for the brake. The annular part outside the core and the insert constitutes an annular stator to which the lateral flanges are fixed and with the bore excentric with respect to the peripheral surface of the insert constituting the outer part of the rotor. The recesses are formed in the cylindrical amagnetic insert and extend radially therein on both sides so that the vanes are movable between a position of complete freedom of the rotor with respect to the annular stator, in which they are positioned close to the rotor core, and a braking position in which they are positioned close to said annular stator, so that, under the effect of a variation in a pre-determined sense of the current passing through the energizing winding, the vanes can be attracted towards said stator and thus define peripheral chambers of different volumes which, by the forced passage of respective volumes of fluid from one chamber to the other, cause between the vanes and the stator a severe throttling and thus the braking torque of the rotor.

Abstract: The present invention concerns the manufacture of objects made of plaster, essentially in the form of boards and, specifically, the pouring onto a moving conveyor of a mixture of plaster and water into a reservoir with an open bottom installed on top of said conveyor. It proposes to integrate the upstream rear wall of the reservoir within a surface of greater dimensions than the rear wall, and displacing said continuously, with the purpose of presenting a different portion of the surface as the upstream rear wall. The invention allows continuous cleaning of the upstream rear wall without disturbing the pouring process.

Abstract: A traversing unit comprises a shaft 42 rotatably mounted in plain bearings 46 and 47 in a housing 41. The housing 41 houses three rings 43, 44 and 45 in contact with the shaft 42 and respectively rotationally supported in ball races 51, 52 and 53 through balls 54, 55 and 56. The rings 43 to 45 may be loaded via a mounted plate 69 comprising bearing-66 to 68 which receive corresponding pins 58, 60 and 62 integrally formed with respective races 51 to 53. This plate 69 is located axially of the shaft 42 by dowels 72 and 73 which are free to move at right angles to the shaft 42. Excess loads caused by reversal torques on the housing 41 when the direction of traverse of the rings is reversed during operation of the unit with the shaft 42 rotating and the rings 43 to 45 loaded are reduced and transferred to bearings 46 and 47 permitting higher loads to be used on the rings43 to 45 and maintenance problems to be reduced as compared with known traversing units.

Abstract: The invention relates to a method of erecting a building in which panels are formed by pouring a filling substance in chute spaces against erected networks. According to a known method of that kind prior to casting the concrete the networks are fastened to a scaffolding frame, which is removed after the concrete has cured. Releasably securing the networks to the scaffolding frame is an operation requiring craftsmanship. The invention has for its object to provide a simple method. For this purpose, in the method embodying the invention, the panels are formed by chute spaces which are formed by filling with a filling substance structural elements consisting of frameworks and networks carried by said frameworks.

Abstract: Esters of  beta , gamma -unsaturated carboxylic acids are prepared by (i) carbonylating a conjugated diene with carbon monoxide in the presence of an alcohol, a halogenated hydracid and a palladium catalyst; (ii) distilling the carbonylation reaction product in the presence of an ammonium, phosphonium or arsonium quaternary onium chloride or bromide having a melting point below the temperature at which the carbonylation reaction is carried out, and at a temperature and pressure such that said reaction product separates into a gaseous phase and a homogeneous liquid phase; (iii) recovering said gaseous phase comprising the ester of the  beta , gamma -unsaturated carboxylic acid corresponding to the reactant diene and alcohol, any unreacted diene and alcohol, and any volatile reaction products of low molecular weight; (iv) recovering said homogeneous liquid phase comprising a mixture of the quaternary onium chloride or bromide and the palladium catalyst, and any non-volatile reaction products of high molecular weight; and (v) recycling, advantageously after removing any reaction products of high molecular weight, the homogeneous liquid phase comprising said mixture of quaternary onium chloride or bromide and the palladium catalyst, into the carbonylation reaction medium.

Abstract: A smoke detector is disclosed containing a radiation source and a radiation receiver arranged externally of a direct radiation region of the radiation source. In the presence of smoke or other combustion particles in the radiation region the radiation receiver is impinged by scattered radiation. The smoke detector contains optical elements which can be altered by external mechanical actuation, by means of which it is possible to alter in a predetermined manner an output signal of the radiation receiver. In this regard it is possible to either mechanically alter the solid angle which is so-to-speak viewed by the radiation receiver or the solid angle irradiated by the radiation source. The constriction of the active solid angle is preferably accomplished by a diaphragm or membrane displaceable along the radiation direction. Displacement of the diagram is preferably achieved in that, this diaphragm engages by means of dogs or detents in a cam groove, such as a helical-shaped groove of a cam disk, and by rotating the cam disk there can be achieved a defined displacement of the diaphragm.
