Patent CA-2125206-C (CA)
Title: Vacuum valve control device and vacuum valve
Inventor: YAMABE YASUO
IPC: G05D16/06
Filed: 1994-06-06
Granted: 2000-07-25
Abstract: The vacuum valve includes: a pressure control chamber for giving a vacuum force to a valve body (changeover valve) capable of connecting a valve operating chamber with a vacuum passage; a detecting valve capable of introducing a vacuum force into the pressure control chamber; a plunger directly driven by a liquid detecting diaphragm, wherein the plunger drives the detecting valve; and an opening time adjusting valve which is opened so that the vacuum introduced into the pressure control chamber can be released, wherein the opening time is automatically controlled by the vacuum in the vacuum discharge pipe. Furthermore, when the inside of a liquid level detecting pipe section is quickly decompressed, pressure in a pressure adjusting chamber is quickly released through a gap formed between a damping diaphragm and supporting section. The pressure adjusting chamber is communicated with an upper pressurizing chamber through a communicating hole. Therefore, when the pressure adjusting chamber is quickly decompressed, the upper pressurizing chamber is also quickly decompressed.      Due to the foregoing, resilient deformation of a liquid level detecting diaphragm is quickly canceled, and the pushing action conducted by a plunger on a detecting valve is released.

Title: Self-energizing fluid treatment apparatus employing external electrodes
Inventor: IBBOTT JACK KENNETH
IPC: F15C1/04
Filed: 1994-07-05
Granted: 2001-01-30
Abstract: In a method and apparatus for treating fluid flowing through piping so as to prevent the deposition of a calcium and magnesium scale on the piping, for example, positive and negative electrodes of electrically conductive materials having different electrochemical potentials are provided on the outer peripheral surface of an electrically insulative tubular member through which the fluid flows. Because the electrodes are disposed out of physical contact with the flowing fluid, the electrodes do not pose an obstacle to the fluid flow nor are the electrodes abraded or worn by particles that may be entrained in the fluid.    Nonetheless, an electroconductive connection between the electrodes is established through the body of fluid by a capacitive effect so that the fluid is ionized.

Title: Method of and apparatus for extrusion molding
Inventor: ANDO YUKIMASA
IPC: B29C48/325
Filed: 1993-12-27
Granted: 2005-04-12
Abstract: According to the invention, a preliminary extrusion is performed to find an optimum back pressure which can provide a predetermined sectional size for respective portions of a movement pattern DA of a movable die, which pattern is determined by a shape of a product. It is assumed that the movable die is positioned at a position DA1 corresponding to a side portion of a product and a value of a back pressure BP, at which a molded material, is made an optimum back pressure BPO. An optimum back pressure for an upper portion of a product is determined in a like manner to decide a pattern of the optimum back pressure BPO. Taking into account time lag, a timing, at which an initial set pattern R1 for rotations of the screw is changed, is set a period of time T11 to T14 ahead of a timing, at which the pattern DA is changed. In a regular extrusion, an actual take-up speed is measured, and when the measured speed is different from that at the time of the preliminary extrusion, the movement pattern DA of the movable die is corrected. When the measured back pressure BP is deviated from the pattern of the optimum back pressure BPO after several cycles of extrusion molding have been executed, the pattern R1 for rotations of the screw is corrected.

Abstract: A reciprocating conveyor floor slat has an upper portion with an upper surface and at least one longitudinally extending ridge projecting upwardly from the upper surface.  The ridge has a longitudinally extending pointed top portion positioned to engage a bottom surface of an article placed on the slat. The pointed top portion is spaced above the top surface a distance sufficient to maintain the bottom surface of the article out of contact with the slat's upper surface as the article is being conveyed.  The preferred number of ridges per slat is two, with the ridges projecting upwardly from laterally opposite portions of the upper surface.  Preferably, the bottom surface of the article being conveyed remains at least about 90% out of contact with the slat.  When articles such as wooden pallets are conveyed, the pointed top portions of the ridges dig  into  the  bottom  surfaces  of  the  pallets  to  form longitudinal grooves to guide longitudinal movement of the pallets.  The low percentage of the area of the bottom surface that contacts the slats minimizes the likelihood of the bottom surface hanging up on the slats.

Abstract: La présente invention concerne un ensemble constituant un cathéter et une partie de cet ensemble. Celui-ci peut être employé pour avoir accès à un tissu cible à l'intérieur du corps, spécialement s'il est accessible par le système vasculaire. L'objet central de l'invention est l'emploi d'un élément de renforcement métallique tressé, particulièrement fait d'un ruban d'alliage d'une très grande élasticité, placé à l'intérieur du cathéter de manière que celui-ci ait une paroi exceptionnellement mince, une rigidité contrôlée, une forte résistance à la déformation et un complet rétablissement in vivo de situations de déformation. La tresse peut être à pas unique ou avoir un pas qui varie le long de l'axe du cathéter ou de la partie de cathéter. L'élément de renforcement en ruban tressé est placé, dans un cas typique, entre un élément de tubage souple extérieur et un autre intérieur, pour donner une partie de cathéter qui soit très flexible mais qui ait une résistance élevée à la déformation. Les parties de cathéter fabriquées selon la présente invention peuvent être utilisées seules ou combinées à d'autres parties fabriquées soit au moyen des idées exposées ici, soit d'autres manières. Les parties plus proximales de l'ensemble constituant le cathéter sont souvent nettement plus rigides que les parties plus distales, et ce en raison de la présence d'un tubage rigide en polymère ou métallique, ou en matériaux composites, dans la partie plus rigide.
