Patent EP-0354796-A1 (EP)
Inventor: BRADLEY JOHN
IPC: A01B29/04
Filed: 1989-08-10
Abstract: An earth working apparatus has a flexible helical coil (12) mounted on a frame (11) for rotation about its longitudinal axis. In operation the coil rotates about a substantially horizontal axis by the effect of contact of the earth with the coil as it is dragged across the ground, for example by a tractor. A means for cleaning the coil (12) comprises a plurality of cleaning and camming bodies (22, 22a, 27, 27a) supported on a shaft (18) which extends substantially parallel to the longitudinal axis of the coil and is mounted on the frame (11) to be reciprocable generally towards and away from said coil. The cleaning and camming bodies (22, 22a, 27, 27a) protrude into, and engage, the coil and are arranged to produce a camming action between said bodies and the coil to move the shaft (18) away from the coil (12) against the action of biassing means (24). The reciprocation of the shaft enables the cleaning and camming bodies (22, 22a, 27, 27a) which protrude into the coil for cleaning, to be moved out of any potential jamming position.

Date May 3, 1990.An adjustable mold for casting stairways of concrete enables the total length of a stairway and also the dimension of the separate steps to be adjusted. The mold includes a longitudinal horizontal frame supporting two identical parallel articulated arm systems positioned scissor-like and being linked together at intersection points of arms of the system along a longitudinal center axis thereof. At oppositely located and linked outer ends of the arms are provided pivotable supports for a number of step units, each of which includes an upstep and an instep. An inner edge of each instep substantially by its own weight rest against the upstep of an adjacent step unit. The total length of the articulated arm link system may be adjusted, thereby simultaneously adjusting the distance between adjacent step units. Also, the angular position of the step units relative to the support frame can be adjusted.

Abstract: The wrist-watch comprises a middle part (18) and a bottom plate (20) made in a single piece in order to form a middle plate (10). The middle plate is entirely covered with a protection layer (60) of substantially constant small thickness. In order to protect the parts (26) of the middle part which are exposed to external stresses (shocks, etc.), the middle plate is carried by two side members (1) fixed on either side of the middle part. These side members are produced so that they have greater resistance to the said external stresses than the middle plate. In particular, the side members (1) are coated with a protection layer (61) which is thicker than the layer (60) coating the middle plate.

Abstract: A compound disc brake comprises a pair of pressure plates (7,11) with a ball and ramp camming mechanism, one of the plates comprises a driven plate (7) keyed to a rotating axle shaft (5) to be braked, and the other plate comprises a servo plate (11) carried from the driven plate by the camming mechanism. The servo plate (11) has a torque-transmitting means in the form of a separate annular disc (20) keyed to the outer peripheral edge of the servo plate. The torque-transmitting means (20) transmits torque applied to that region by primary braking means (23; 50) to the central region of the servo plate. Retardation of the servo plate by the primary braking means causes the pressure plates to separate axially and move into engagement with relatively stationary braking surfaces (2,3) in the brake housing 1 whereafter servo braking occurs. The brake includes a mechanically operable parking brake which acts on the torque-transmitting means (20) and comprises an annular ring (40;50) concentric with the shaft (5) and having camming means to produce axial movement when it is moved angularly by an arm (43;55) extending through a circumferential slot (44). The annular ring of the parking brake may comprise a hydraulic annular piston (50) which is also used for normal service braking, or may be a separate ring (40).

Abstract: Procédé permettant de produire du spiroorthocarbonate bis-méthylène (BMSOC) où l'on met en contact du chlorure de méthyallyle avec du gaz chloré pour former un mélange de 1,1-dichlorométhyle éthylène et d'autres hydrocarbures chlorurés qui ne sont pas séparés ni ne doivent l'être. On traite ensuite simplement ledit mélange avec un acétate de métal alcalin, tel que l'acétate de sodium, pour obtenir un second mélange facilement séparable par distillation fractionnée. On peut ainsi récupérer le 1,1-diacétoxyméthyle éthylène voulu en grande quantité, que l'on convertit ensuite par transestérification en spiroorthocarbonate bisméthylène (BMSOC) à plus de 90 %. Le BMSOC est un composant utile pour les revêtements, les complexes et autres formules d'adhésif, qui présentent la propriété unique de a) vulcaniser par initiation radiale libre et b) se dilater pendant la vulcanisation. On peut utiliser le BMSOC comme composant pour les composites dentaires, par exemple les matières de remplissage, en raison de sa plus grande étanchéité aux bords, par exemple à la jonction émail/composite, et comme composant dans les ciments d'os. Il se prête également au remplissage de vides dans les revêtements électriques isolants en raison de sa faible propension à la décharge diélectrique et/ou en effet corona.

Abstract: A power source circuit consisting of a combination of a constant-voltage circuit (1) and a voltage raising/lowering circuit (2) which produces a plurality of output voltages by raising or lowering the output of the constant-voltage circuit. When a change in the power source voltage or the presence or absence of a heavy load is detected that information is supplied as a control mode signal to both the circuit (1) and circuit (2). For instance, when the power source voltage is reduced or when a heavy load is driven, the output voltage of the circuit (1) is lowered and instead the rate of change in the output voltage of the circuit (2) is adjusted so that the output voltage may eventually become the same as in steady state.
