Abstract: A lawn and bush cutting device comprises a housing (1) mounted for rotation about an axis with a drive shaft (11) fixed to the housing and drivable by a motor for rotating the housing. A wire cylinder (27) is coaxially mounted in the housing and can be held fixed with respect to the housing (1) for rotation therewith. A supply of cutting wire (F1-F2 ) is wound on the wire cylinder, or on a reel rotatably fixed to the wire cylinder. A length of the wire (F1-F2) extends out of the housing (1) to act as a cutting tool when the housing rotates. A sleeve member (33) is axially movable in the housing and has helical coupling piece (35) which are coupled to helical piece in the cylinder (27). Axial movement of the sleeve (33) thus causes relative rotation between the wire cylinder (27) and housing (1), thus paying out additional lengths of wire from the housing. A ring (23) is axially movable but rotationally fixed to the sleeve (33) and can be moved downwardly by cable operated member. The ring has recesses which engage projections of the sleeve member so that, with the ring lowered, the sleeve member is engaged and can be forced further downwardly to cause relate rotation between the wire cylinder and the housing. The ring also includes teeth which engage the cylinder for holding the cylinder rotationally fixed with the shaft when the ring is disengaged from the sleeve member, and for disengagement from the cylinder when the ring is engaged with the sleeve member.

Abstract: In order to secure a body (16) in a predetermined position a multi-­jointed arm is required, the body (16) being applied in the free end (3) of the arm, the other end (1) of the arm being firmly secured and the joints being locked with the aid of screw joints when said body (16) has been positioned as desired. This is difficult to achieve since it is difficult to adjust the screw joint accurately. Furthermore, it is difficult to make screw joints sufficiently resistant to torsional forces. These drawbacks are eliminated according to the invention by applying hydraulic pressure on at least one (35) of two cooperating surfaces (34 and 35) by means of a pressure medium.

Abstract: Procédé d'injection de carburant dans un moteur à combustion interne multi-cylindres. En fonction de signaux de référence synchrones avec le vilebrequin, des signaux d'ouverture sont produits pour les soupapes injectrices respectives de chaque cylindre, toutes les soupapes injectrices étant d'abord actionnées ensemble après mise sous tension de l'allumage et les signaux d'ouverture en vue de l'injection séquentielle de carburant étant produits après la reconnaissance de la synchronisation. Le problème à résoudre est de pouvoir, après lancement du moteur ou après mauvais fonctionnement de la synchronisation, passer rapidement à l'injection séquentielle de carburant, la quantité de carburant injectée dans les soupapes d'admission ouvertes devant être réduite au minimum. On propose à cet effet que dans une phase (a) jusqu'à la reconnaissance de la synchronisation, au moins en cas de nouvel allumage, les signaux soient amenés, notamment simultanément, aux soupapes injectrices. De plus, dans une phase (b) suivant la reconnaissance de la synchronisation, les signaux d'ouverture sont amenés simultanément aux soupapes injectrices pour les cylindres n'étant pas encore passés au mode de fonctionnement séquentiel.

Abstract: In this process for managing passenger traffic at the main stop (HAUPTHALT) of a lift group with n lift cages, sensors (SENSOR. A; SENSOR. B ... SENSOR. N) monitor entering passenger traffic and sensors (SENSOR. 1; SENSOR. 2 ... SENSOR. N) monitor exiting, building-filling passenger traffic. The higher-order algorithm (REGLER) implemented in the processor (RECHNER) determines the traffic volume and the actual departure load of the lift group from the sensor data. Depending on the traffic volume, the actual departure load and constants imported from the input/output unit (TERMINAL), the higher- order algorithm calculates the carrying capacity of the lift group according to a control algorithm. The carrying capacity of the lift group is assigned to the lower-order algorithms (REGLER. 1; REGLER. 2 ... REGLER. n) according to the number of lift cages and the nominal load of the relevant lift cage. The lower-order algorithm of the relevant lift cage calculates the optimum departure load on the basis of the assigned carrying capacity and the circulation time of the relevant lift cage. Depending on the optimum departure load and the actual departure load of the relevant lift cage, the lower-order algorithm determines, according to a control algorithm, the adjusted departure load which is to be imposed on the relevant lift cage.

Abstract: A fuel injection pumping apparatus for supplying fuel to a compression ignition engine has an annular cam ring which has internal cam lobes for imparting inward movement through cam followers respectively to pumping plungers mounted in a rotary distributor member. Stop rings are mounted alongside the cam ring to determine the maximum outward movement of the plungers. The stop rings are angularly adjustable to enable the maximum amount of fuel supplied to the engine to be varied. Two adjusting devices are provided the first being a piston (37) which is subject to a fluid pressure varying with speed. The piston is biased by a spring and sets the stop rings to allow an excess of fuel for engine starting purposes and the second is a diaphragm assembly responsive to the air pressure in the engine inlet manifold. In order to save space the piston is slidable within a housing (34) which also accommodates the diaphragm assembly and the diaphragm assembly is coupled to the stop rings by means of a push rod (54) which passes through an aperture in the piston.

Abstract: A copper chromite hydrogenation catalyst of enhanced activity is obtained by an ante-pre-reduction treatment in which a copper chromite catalyst precursor is soaked in a reducing atmosphere at temperatures below a pre-­reduction temperature (typically about 140°C) at which appreciable pre-reduction of the catalyst can be detected. This catalyst is characterised by particles of reduced copper substantially all of which have an average particle size of less than about 300 x 10⁻¹⁰m (300Å), which have an average particle size of less than about 100 x 10⁻¹⁰m (100Å), and which are substantially uniformly distributed on a chromium-containing support. Typically such catalysts exhibit a copper surface area of about 18.5 m²/g as determined by N₂O decomposition at 20°C, compared to a corresponding copper surface area of 4.5 m²/g for a catalyst which has been produced by conventional pre-reduction of the same catalyst precursor.

Abstract: A group control for an elevator system assigns immediately destination calls which were entered at a floor lying behind the car in the direction of travel of the car and for a floor which lies ahead of the car. The group control includes a call memory having a first register for storing the calls of like direction of travel entered ahead of the car, a second register for storing the calls of opposite direction of travel and a third register for storing the calls of like direction of travel entered behind the car. A control circuit is activated each time a call is entered such that a call of the same direction of travel is written, according to its position with respect to the car, into the first or third register. The allocated calls of the third register are transferred into the second register on the first change in direction of travel of the car and into the first register on the second change in direction of travel so that they can be detected by a selector addressing the call memory.
