Inventor: ENRIGHT PHILIP GRAHAM
IPC: B22D11/04
Filed: 1983-10-06
Abstract: In the casting of ingots (9) of aluminium alloys, containing a readily oxidisable component, in an openended mould (2), a space is enclosed over the molten metal surface adjacent the mould wall and is filled with an inert gas. The enclosure is maintained by a baffle (4) which dips into the molten metal surface close to the baffle. The molten metal surface between the baffle and the mould wall is preferably covered by a layer of an oxide-dissolving flux, which cleanses the mould wall at the metal meniscus/mould wall interface.

Abstract: Les véhicules de terrassement sont souvant pourvus d'un mécanisme de liaison à une extrémité, lequel est utilisé pour manipuler un outil de tavail, tel qu'un godet de chargement. La liaison comprend généralement un agencement de basculement du godet qui comporte un levier de basculement monté sur un bras de levage qui supporte le godet. Le montage entre le levier de basculement et le bras de levage est en général de nature complexe nécessitant de nombreuses surfaces portantes et des moyens de lubrification. D'autres systèmes peuvent comporter une structure nécessitant un positionnement précis entre les composants sous peine d'une défaillance due à un chargement inapproprié. Le mécanisme de liaison (10) de la présente invention consiste en un organe de montage (82) qui est fixé uniquement à l'un des leviers de basculement (56, 58). Il comprend également un limiteur de mouvement axial (84) qui est fixéà l'autre levier de basculement (56, 58). De cette manière, on obtient un dispositif de montage (62) très simple et économique. Le dispositif de montage (62) permet également aux leviers de basculement (56, 58) de tourner l'un par rapport à l'autre et porter ainsi une partie du chargement.

Abstract: A flexible all-steel shaft coupling has two coupling halves each comprising a connecting flange and which are axially and angularly movable but antitorsionally connected to each other through a yieldable stapled lamella crown connected to the connecting flanges. Each connection of the stapled lamella crown with one of flanges consists of a bolt on which rests, in clamped position between spacer rings, the stapled lamella crown on a spring collet provided with a conical press seat. Due to its conical support on the bolt, the conical spring collet is radially expanded and transmits radial pretension into bores of the stapled lamella crown. Due to the tolerance-free support of the stapled lamella crown on the bolt, and due to radial pretension in the bores of the stapled lamella crown, the shaft coupling may be easily mounted without precision machning and without tolerance on the support seats, while expansions and ovalizations of the bores, which lead to ruptures due to notch corrosion are prevented.

Abstract: A position transmitter (8) includes a d c power supply (10) having a positive terminal connected to an input line (12) and a negative terminal connected, through a system controller (14) having a variable load. to an output line (16). A voltage divider including a potentiometer (30 !  is connected across the input and output lines (12. 16). A wiper (281 of the potentiometer (30) is mechanically connected to a movable member (24) of an actuator device (22) so that a variable voltage is applied between the input and output lines (12, 16). The wiper (28) is electrically connected to a negative input of a zero adjust amplifier (50) which has an adjustable positive input. The movable member (24) is moved to its zero position which also moves the wiper (28) to a zero position. At the zero position, the zero adjust amplifier (50) is adjusted to apply a 4 mA current to the output line (16). This is done by applying the output of the zero adjust amplifier (50) through a series of amplifiers to the base of a transistor (60), which has an emitter and collector connected across the input and output lines (12, 16) for converting the voltage signal into a current signal. A span adjust amplifier (54) has a negative input connected to the output of the zero adjust amplifier (50) and has an adjustable feedback (56) from its output to its negative input. The movable member (24) is moved to its maximum position, thus also moving the wiper (28) to a maximum position. The span adjust amplifier (54) is then controlled to apply a 20 mA current signal to the output line (16). As the movable member (24) moves between its minimum and maximum position, a 4-20 mA signal which corresponds to the position of the movable member is applied to the output of the position transmitter.
