IPC: B22D17/00
Filed: 1991-11-05
Abstract: Shaped metal articles are produced on a continuous basis from semisolid metal preforms. The metal preforms are sequentially heated, then transferred, without substantial deformation or heat loss to a press where they are shaped in the semisolid state into shaped articles. While in the press, a ram is employed to drive the preform into a cavity of adjacent tooling to thereby shape the article. Prior to the forming operation, the ram is first advanced until it lightly engages the preform, then is withdrawn by a spaced distance to a first position defining the beginning of a stroke. Then, the ram is advanced, rapidly, from the first position against the preform to a second position contiguous with the tooling, thereby defining the end of the stroke. The spaced distance is chosen so as to preclude substantial heat drain from the preform and/or forced entry of air into the cavity and/or splashing of the semisolid metal outside of the cavity. Just before reaching the second position, the ram may be accelerated to preclude the formation of voids in the finished article.

Title: Pumping device and containers fitted therewith
Inventor: SAITA SEIJI
IPC: F04B9/125
Filed: 1991-11-29
Abstract: A reciprocating actuator is axially connected to drive a reciprocating pump. An exhaust tube (52), open to the outside, passes through a piston (21) of the reciprocating actuator and into an inner hole (62) axially disposed in a working rod that connects an actuator piston (21) of the reciprocating actuator to the reciprocating pump. A valve mechanism (31) communicates a chamber (26) above the actuator piston (21) with the inner hole (62) during upward motion of the piston (21), whereby actuator fluid above the piston (21) is exhausted to the outside through the exhaust tube (52). The resulting axial exhausting of the actuating fluid permits inserting a large portion of the device into a drum for pumping of liquid. The invention permits use of a two-stage rod system, which is capable of obtaining high pumping pressure. The inner hole (62) is communicated with a space whose volume changes when the working rod makes a vertical movement. Different piston sizes can be used in the reciprocating actuator and the reciprocating pump, whereby higher or lower pump pressure is attainable.

Abstract: The invention relates to a process for determining the use characteristics of a prosthesis shaft (1), in particular a leg prosthesis shaft (1), during fitting of the shaft (1) using a supporting apparatus (2) for the shaft (1). The supporting apparatus (2) for the prosthesis shaft (1) can be pivoted about at least one axis, but preferably about at least two axes (5,6) which intersect one another and are in particular perpendicular to one another. After the stump of the limb, in particular the leg stump, has been introduced into the prosthesis shaft (1), the axis or the axes of intersection of the supporting apparatus is adjusted to the centre (the central area) of the natural joint of the limb stump, in particular the leg stump, or to the centre of gravity of the patient trying out the shaft (1). Thereafter the prosthesis shaft (1) is moved by means of the limb stump, and the limits of the mobility of the limb stump, in particular leg stump, introduced into the limb prosthesis shaft (1), in particular leg prosthesis shaft (1), are established by means of coordinates as actual values, and the actual values are compared with standardised desired values for the purpose of assessing the mobility restriction with regard to its acceptability. As a result of the discrepancy between the desired value and the actual value at each position of the prosthesis shaft (1), changes are made, for example in the bed of the stump, in order to reduce in this position the discrepancy between the desired value and actual value of the mobility of the limb prosthesis shaft (1), in particular the leg prosthesis shaft (1).

Patent EP-0525080-A1 (EP)
Title: Medical valve assembly.
Inventor: ROGERS BOBBY E
IPC: A61M39/26
Filed: 1991-04-09
Abstract: A medical valve assembly is described in which the valve assembly has a female luer lock portion on an inlet end of the device and a male luer lock portion on the outlet portion of the valve. A movable piston seals the inlet portion of the valve from the outlet portion when the piston is in the closed position. When a syringe is attached to the inlet portion of the valve assembly, the piston is displaced in a manner that unseals a fluid channel inlet. This connects the end of the syringe to the fluid channel which is connected, at its outlet end, to a catheter or other device, connected to a patient. Thus, medication can be introduced to, or fluids aspirated from, a patient's bloodstream, without the use of a syringe having a needle. When the syringe is removed from the inlet to the valve assembly, the piston is urged by a biasing means into its original closed position creating a seal between the inlet portion of the valve and the outlet portion of the valve. This feature maintains catheter patency. The top surface of the piston along with the area of the female luer lock connector does not have any fluid reservoir and can be easily cleaned to prevent the possibility of bacterial infection as a result of repeated uses of the valve assembly.

Abstract: La présente invention se rapporte à un procédé pour régler le cyle de moulage d'une machine de moulage par injection pourvue d'un mécanisme d'ouverture/fermeture de passage d'écoulement, permettant d'interrompre le flux de résine synthétique plastique injectée, et se propose de réduire la durée d'un cycle de moulage et de stabiliser la valeur pondérale du produit. La structure est telle que ledit mécanisme d'ouverture/fermeture de passage d'écoulement est fermé lorsque la résine synthétique remplie les empreintes des moules métalliques après injection et dégazage. Cette structure permet le déroulement simultané du processus de dégazage par dégazage résiduel côté moule métallique, et du processus de mesure pondérale pour le cycle de moulage suivant côté vis, la durée d'un cycle de moulage pouvant être réduite. La présence du mécanisme d'ouverture/fermeture de passage d'écoulement et d'un clapet de non-retour pour la vis permet d'obtenir sous forme de valeur définie la pression de résine synthétique dans le cylindre immédiatement avant l'injection et pendant le dégazage. La valeur pondérale du produit calculée permet de régler la machine de moulage par injection de manière à maintenir constant le poids du produit moulé.
