Abstract: Fasteners (1) are to be screwed in and/or driven in using a device, a profile part (3) which has webs (5) projecting in the direction of the fastener head (2) being arranged under the fastener head (2). To achieve exact alignment of the projecting web (5) while the fastener (1) is being screwed in or driven in, a slot (8), which is aligned axially parallel to the screwing or driving spindle (7), is open in the screwing-in or driving-in direction and into which the web (5) of the profile part (3) can be inserted or pushed, is provided, spaced apart, beside a receiving part (4), which performs the screwing and/or driving movement, receives the fastener head (2) and is connected to a drive unit (6). The profile part (3) is thereby held in exact alignment while the fastener is being screwed in and/or driven in. <IMAGE>

Abstract: The door closer is provided at its interior with seal means (3-3') and with other means, which are such that owing to these means, when the door closer moving element is in its opened door-locking position, the pressure chambers (G1-G3) between which oil should be allowed to flow, are thoroughly isolated from each other. Connected between these chambers is at least one unlocking valve (4) which normally is in closed condition, while when a door is being pushed into its closed position, and an over-pressure is formed in chamber (G1), whose volume decreases during the door-closing stroke of the door closer, the said valve is affected by the said pressure peak and is set in open condition, thus allowing the door closer moving element to be returned into rest position. During the door-closing stroke of the said moving element, the unlocking valve is isolated from the pressure chamber (G1) whose volume is decreasing, and is automatically reset, and the door closer moving element will complete its door-closing stroke under the control of conventional, adjustable valve means (V) provided in the same. The setting of the unlocking valve (4) can be removed any time a door closer should be used without the locking of a door in opened position being required.

Abstract: 5 n7 A casing assembly for electronic equipment comprises a printed board on which an exothermic electronic component is mounted, a casing for covering the printed board, and a base for attaching the casing to a wall body or a rail. The base is made of high heat conductive material and has a planar structure which results in a large contact area between it and the wall body or the rail. A high heat conductive plate-like cushioning member made of electrically insulative material is interposed between the printed board and the base in contact with them. The heat generated in the electronic component is released through the printed board and lead wires and through the cushioning member and the base to the wall body or the rail. Preferably, where the casing is to be attached to the rail, a guide latch member and a pressure latch member are attached to the base. Where an auxiliary printed board is to be provided in addition to the printed board, the base, printed board, auxiliary frame and auxiliary printed board are piled up in that order and covered with the casing. Where a programmer is to be attached to the casing, provisions are made for accommodating two, horizontal and vertical attaching directions. Where the functions of a basic module supported by the casing are insufficient, extended modules are connected.

Abstract: A paging signalling system communicates messages via a synchronous signal. The synchronous signal is divided into a plurality of frames (100) in which selective groups of pagers decode. A signal (102) within the frame (100) causes groups of pagers to decode in various frame (104, 106), wherein several groups of pagers may be combined into a signal frame to decode messages (110). Embodiments of the invention include first type of a plurality of groups of pagers, each group having a common maximum frame rate, a second type of a single group of pagers having a unique maximum frame rate, and a third type of a single group of pagers having no maximum frame rate. The three types of groups may decode the synchronous signal.

The switch also has centering devices that extend parallel to each other, without offset, from a first end of a base plate to a second end of the base plate. The centering devices secure a plurality of light wave guides each extending through the coupling plane when each of the wave guides forms a single component. The method includes the steps of coupling the first end of the base plate to a stationary part of the switch and coupling a second end of the base plate to a drivable part of the switch while the switch is in the given switching position. The method also includes the steps of cutting the light wave guides with a laser in the coupling plane and cutting the base plate in the region of the coupling plane.

Abstract: Procédé et éjecteur amélioré destinés à produire des particules explosives ultrafines. Lesdites particules explosives, lorsqu'elles sont incorporées à un agent liant, ont la capacité de se propager en feuilles minces et elles ont une sensibilité très faible aux impacts et une sensibilité très élevée à la propagation. Un courant d'une solution de l'explosif dissous dans un solvant est soigneusement mélangé à un courant d'un non-solvant inerte de manière à obtenir un flux non laminaire des courants en appliquant une pression contre le flux du courant de non-solvant afin, par là-même, de faire diverger le courant lorsqu'il entre en contact avec la solution explosive, et en agitant violemment le courant combiné pour précipiter rapidement les particules explosives de la solution sous forme de particules ultrafines, généralement sphériques. Les deux courants sont injectés coaxialement à travers les orifices continus concentriques d'une tuyère dans une chambre de mélange. De préférence, le courant de non-solvant est injecté centralement par rapport au courant de solution explosive. Ledit courant de solution explosive est injecté en aval du courant de solution non-solvante et entoure ce dernier sur une distance assez importante, avant d'être éjecté dans la chambre de mélange.
