Abstract: Hip-joint prosthesis with an essentially cylindrical first shaft part, which is situated in the vicinity of the end near the joint and which has, inclined obliquely in the direction of this end, a lateral extension for the ball of the joint. In its area adjoining the shaft, the extension has a substantially greater dimension in the direction of the shaft than it does tangentially thereto. A second shaft part can be attached to that part bearing the extension, which second shaft part projects over the first-mentioned part in the direction away from the joint end. The second part can be pushed essentially completely over that part bearing the extension and can be fixed at the end of the shaft part near the joint. The extension extends through a slot in the second shaft part in such a way that the extension attachment is situated essentially in the slot.

Abstract: An overcurrent detector realized by using a microcomputer. The apparatus is provided with an overcurrent determining means (5) which calculates the temperature rise e(n) = K1P(n) + K2θ(n-1) relying upon a current (In) that flows into the load, under the conditions of the load having electric resistance (r), ambient temperature at which the load is used, an allowable temperature rise {θ(max)) of the load, a first coefficient (K1) and a second coefficient (K2). The overcurrent determining means (5) further compares said temperature rise (θ(n)) with a difference between the allowable temperature rise (θ(max)) of the load and the ambient temperature at which the load is used, and determines the difference in current to be an overcurrent when the former exceeds the latter.

Abstract: Des rotors (3) et une cage (4) se déplacent sur une surface routière en fonction de la rotation d'une roue (7), et, tant qu'il existe un mouvement relatif entre la roue (7) et la surface routière (5), un élément analogue à une chaîne est animé d'un mouvement de rotation. Tandis que le véhicule se déplace normalement, la roue tourne sur une lame placée de manière fixe sur la surface de la route; et, même lorsque la roue patine, elle entraîne la lame vers l'arrière en glissant, faisant ainsi tourner l'élément analogue à une chaîne. Lorsque la roue et la lame patinent sur la surface de la route lorsque la roue est freinée, ladite surface fait tourner l'élément analogue à une chaîne. En conséquence, les lames s'abaissent séquentiellement en toute circonstance pour s'appliquer sur la surface routière en bon ordre et s'immobiliser, et la roue tourne sur les lames en passant dessus. L'accrochage de la lame s'effectue donc de manière fiable. Même lorsque les lames sont de faible dimension, il n'est pas nécessaire de leur appliquer un effort excessivement important, et cela permet de réduire les dimensions du moyen de fixation des lames.

In this process polyepoxides and compounds containing one or more, preferably 2, hydroxyl groups per molecule are reacted at elevated temperatures in the presence of catalysts to furnish epoxide-containing intermediates. A solvent or a mixture of solvents is then added with external cooling ahd the solution is boiled under reflux, if necessary in vacuo, until the temperature of the solution drops to 95 DEG  C. to 20 DEG  C. Amines are then added onto the epoxide groups which are still present in a free state in the epoxy resin and a dispersion is prepared by adding a water/acid mixture after adding the crosslinking agent or the dispersion is first prepared and the crosslinking agent is added subsequently.

Abstract: A center entry valve gated injection molding system having a heated nozzle (14) secured in front of a heated manifold (18) with at least a pair of valve member biasing mechanisms (94) extending radially outward from a reciprocating elongated valve member. The melt passage (88) splits into two branches (92) which extend through a manifold (18) outwardly around a rear portion (56) of the valve member (10). The two branches (92) of the melt passage (88) and the two biasing mechanisms (94) are alternatively evenly angularly spaced around the valve member (10) which considerably reduces the space required. The valve member has an enlarged forward end (62) which opens forwardly into the cavity and is closed in a retracted position in which it seats in the matching mouth (50) of a gate (48) in a nose portion (32) of the nozzle (14). Each biasing mechanism (94) includes a compression spring (96) which engages a lever member (100) to continuously urge the valve member (10) rearwardly. When injection pressure is applied it overcome the force of the springs (96) and moves the valve member (10) forwardly to the open position. When the cavity is filled, the combination of the back pressure of the melt and the force of the springs (96) with a mechanical advantage from the lever members (100) withdraws the valve member (10) to the closed position. In an alternate embodiment, only a single biasing mechanism (94) is utilized.

Abstract: A process for forming an MOS transistor with self-­aligned contact holes comprises first forming a conductive layer of material over the substrate followed by formation of a capping layer of oxide over the conductive layer. The conductive layer and capping oxide layer are then patterned to form the gate electrode of a transistor with source/drain regions defined on either side thereof. A conformal layer of oxide is then disposed over the substrate and anisotropically etched to remove the oxide layer from the horizontal surfaces leaving a sidewall oxide layer on all substantially vertical surfaces. Thereafter, a second layer of conductive material is deposited over the substrate and patterned to form contacts.

Abstract: A method of insolubilizing noxious heavy metals contained in the fly ash collected from a waste gas discharged from a garbage incinerator. In order to make insolubilize the heavy metals, a chelating agent and water are added to the ash, and these materials are kneaded together to obtain a kneaded mass. This mass has a high alkalinity due to an alkaline substance added to the waste gas for the purpose of removing hydrogen chloride therefrom. The quantity of the water to be added to the ash is regulated so as to lower the pH value of the kneaded mass to 12 or below, whereby the reaction between the heavy metals and the chelating agent in the kneaded mass is promoted. Thus, the heavy metals are converted into water-insoluble chelate compounds owing to this reaction.
