Abstract: In the apparatus, a movable platen displaceably mounted on guide pins can be locked by means of supporting devices in a locking unit likewise displaceably mounted on the guide pins. The locking unit is for its part supported by means of a hydraulic closing ram in a supporting block, in which the closing cylinder is formed and in which the guide pins are anchored. To simplify the production of the hydraulic unit comprising closing ram and closing cylinder and to improve sealing, it is proposed to design the control piston as a plunger-stepped piston and to arrange inside the plunger-stepped piston a stepped piston, the piston rod of which passes through the plunger, stepped piston surface and is firmly connected to the supporting block. By applying pressure medium to the stepped piston surface facing the locking unit and the plunger-stepped piston surface through which the piston rod of the stepped piston passes, the closing operation is effected and, by applying pressure to the stepped piston surface facing away from the locking unit, the breakaway stroke is effected. <IMAGE>

Abstract: To enable the operation of a cement manufacturing installation to be controlled by taking into account changes in essential operating parameters as soon as they appear, the quantity of the total theoretical heat (QT) required to convert the raw material to clinker is calculated by applying correcting coefficients to the quantity of a predetermined total nominal heat (QTO) corresponding to nominal values imposed by parameters (K1, K2, . . . Kn) characteristic of the raw material, of the fuel, of the clinker and of the operation of the installation, the correcting coefficients taking into account differences between the nominal values and measured values of said parameters. The quantity of the theoretical heat (QF) to be supplied to the kiln is calculated by deducting the quantity of heat (QP) supplied to the precalcination chamber from the quantity of total theoretical heat (QT). A consigned value (FF1) of flow of the fuel supplied to the kiln is calculated on the basis of the quantity of the theoretical heat (QF) to be supplied to the kiln, and the actual consigned value (FFO) of the flow control is progressively modified until it has reached the calculated consigned value (FF1) of fuel flow, the progress of variations imposed on the consigned value depending on the conditions of thermal treatment of the raw material and of its dwell time in the kiln. These steps are periodically repeated at relatively close intervals of time.

Abstract: The measuring method is used for local measurement of pressures by means of a matrix-like measuring arrangement (5) which has intersecting rows (6) and columns (4) of in each case pressure-transmitting conductors. Here, optical fibres are used as conductors, those of the rows and of the columns being arranged in such a way that pressures differing locally at their intersections produce contact surfaces of varying size. If light from at least one end is then fed into only a single row or column optical fibre and the quantity of light coupled in at the intersections is read out at all optical fibres intersecting this optical fibre, a locally resolved distribution of pressure can be obtained.

Abstract: The disclosure relates to a powder flow control valve comprising a nozzle (33) formed from a material such as high density polythene having an upper frusto-conical section (33a) which converges towards the lower end of the nozzle and terminates in a cylindrical section (33b). The nozzle is encircled by a plenum chamber (24) to which sources of vacuum and air pressure are selectively connectable through a pneumatic control system (14). When vacuum is connected to the plenum chamber, the resulting pressure drop across the wall of the porous nozzle causes powder flowing through the nozzle to consolidate in the nozzle and terminate the flow. When air pressure is applied to the plenum chamber, the resulting pressure rise across the boundary surface accelerates powder flow through the nozzle. The control means is arranged to establish air pressure in the plenum chamber to initiate opening of the valve and flow through the valve and, after a pre-determined time, to terminate the air pressure supply and allow powder to flow under gravity through the nozzle before flow is terminated when a pre-determined quantity of powder has been delivered by the nozzle by applying vacuum to the plenum chamber.

Abstract: The sliding door of showcases is normally closed by means of safety locks, but these have to be installed with a high degree of accuracy if the side wall is to have no play in the position of rest. The new device will likewise make it possible to close a showcase securely, but without having to ensure particular accuracy during installation. The sliding door 4 is held in the closing position or position of rest by permanent magnets 7 which are attached to the showcase and the magnetic field of which can be cancelled via an electrical winding by the flow of an appropriate direct current. Since the permanent magnets do not have to be installed with such accuracy, the assembly of a showcase of this type can also be carried out outside a workshop, for example a building site. Furthermore, the secure closing of sliding doors can thus be brought about, even in places where conventional closing devices would be accessible only with difficulty.

Abstract: An attempt was made to cool the machine directly with running water. This process has proved unsuitable, for technical reasons, because the water becomes highly polluted. The aim of the present invention is to obtain a cooling system of the above-mentioned type which does not suffer from the drawbacks mentioned and which can be used in installations with mass-produced cylindrical rotors in the medium machine range. A generator (2) connected upstream to a transmission (3) is arranged in a chamber (1) immersed in water. The transmission (3) is driven by a slowly rotating turbine (not shown). The wall of the chamber (4) consists of a sheet metal casing. The wall of the chamber (4) facing the direction of flow constitutes a cooling radiator (5). The invention makes it possible for the first time to produce immersible aggregates which operate economically even in the low-output range. This is primarily due to the fact that mass-produced generators can be used.

Abstract: A trapezoidal non-pneumatic tire ("TNPT") is integrally molded from a stiff, resilient elastomeric material with particular specifications, to form a unitary structure comprising outer and inner cylindrical coaxial members ("hoops"), the outer being wider than the inner. The outer hoop is supported and cushioned by a plurality of circumferentially spaced apart, planar rib members (ribs) and a planar central web member (web) which connects the hoops at their circumferential center lines. The web lies in a plane perpendicular to the rotational axis of the TNPT. The ribs extend axially along the inner and outer hoops, connecting them, and the edges of the ribs lie along the opposite faces of the web. The ribs are angled in the range from 15 DEG  to 75 DEG  to radial planes which interesect them at their radially inner ends, and the ribs on one side of the web are angled oppositely from those on the other. A rubber tread is secured to the outer surface of the outer hoop. The coaction of the structural elements of the TNPT provides a load-supporting structure which, in operation, is subjected to continuous compression and tensile forces as it travels over the ground. Deformation and buckling characteristics of the TNPT are derived from its unique trapezoidal shape which results in an interaction of the structural elements such that the outer hoop is not pulled under the wheel as much as the outer hoop would have been, had the shape of the TNPT been rectangular. The trapezoidal shape provides the TNPT with improved "handling" characteristics in hard turns without sacrificing a "ride" which is surprisingly similar to that of a conventional pneumatic tire.

Abstract: The invention relates to an electrical installation apparatus, especially a safety socket. This installation apparatus has a supporting ring with retaining webs which hold a base of insulating material. The electrical connecting contacts, the earth clip and, if applicable, mechanical retaining elements and the like, are accommodated thereon. A board having overvoltage protection elements is also allocated to the insulating material base. The effectiveness of the overvoltage protection elements is indicated by means of a signalling device. The electrical installation apparatus also includes an insulating material housing which at least partially surrounds the insulating material base. This insulating material housing, together with the parts located inside it, is accommodated in the interior of a retaining socket, especially a flush-mounted socket. While the signalling device for indicating the effectiveness has in the past always been constructed as an optical signalling device it is now proposed to use an accoustic signalling device. This may consist, for example, of accoustic signalling devices of the type known under the designation "buzzers". In order to facilitate economical production of the electrical installation apparatus, it is provided for the insulating material housing to be fixed to parts of a commercially available electrical installation apparatus, which exists in any case. This can take place, for example, in such a manner that the insulating material housing is attached to the retaining webs of the supporting ring of the installation apparatus. <IMAGE>
