Patent CA-2225287-A1 (CA)
Inventor: ZHUANG HELEN
IPC: B29C45/16
Filed: 1997-12-18
Abstract: Valve gated injection molding apparatus having three position valve member actuating mechanism for multi-layer molding. A first melt passage extends to the gate through an annular channel in a heated nozzle, while a second melt passage extends around an elongated valve member in a central melt channel. A rack member engaging the rear end of the valve member is driven by a pinion member connected to a front piston in a front cylinder. A rear piston in a shorter rear cylinder aligned with the front cylinder has a stem extending forwardly into the front cylinder. First, air pressure applied behind the rear piston retracts the valve member from a first closed position to a second partially open position wherein melt flows only through the annular channel. Then, air pressure applied behind the front piston retracts the valve member to a third fully open position wherein melt flows simultaneously through both melt channels to provide the three layers. When the cavity is nearly full, air pressure is released behind and applied in front of the front piston to return the valve member to the second position until the cavity is full. Air pressure is then released behind the third piston to advance the valve member to the first closed position in which its front end is seated in the gate for ejection.

Abstract: THE MULTI SHED        INTRODUCTION:   1A: In a shed or shelter it is known that most of them are used for one purpose. This shed can have multiple uses. The shed does not require the use of mechanical devices to hold it together. The shed will have a number of different covers to close it in. The shed requires a light weight hammer or a block of wood to assemble. A hammer is needed to drive the hold down parts into the ground. Hold down parts will be six tent pegs that hook onto rope or wire around the perimeter of shed. The shed is held together by ropes or plastic covered wire which fits into grooves that are cut in the outer edge of the frame. The frame is made from a recycled plastic material that is very ridgid, strong and light weight.      This invention relates to a shelter for multiple use. It is common in shelters of this type to require nails, screws, or bolts to hold it together. This shelter does not require any of these fasteners. 2A: This shelter requires the use of rope made from natural material or plastic material or metal wire covered in plastic.      We have found that it is time consuming and difficult to assemble most sheds when they have so many fasteners required for assembly. This shed requires very little time to assemble, as it does not have all these extra parts.

Inventor: KISMAN KENNETH E
IPC: E21B43/38
Filed: 1998-01-30
Abstract: Apparatus and method are provided for producing fluid from a wellbore extending into a hot subterranean hydrocarbon-bearing formation containing water at greater than 100 °C. The wellbore is divided into three co-extensive passageways; an annulus, and first and second conduits. The annulus is formed within the wellbore between a block at its bottom above the completion intervals and an outlet at the wellhead. The first conduit extends from the formation, through the bottom of the annulus and to an outlet at an elevation intermediate up the annulus. The first conduit is insulated between the bottom of the annulus and its outlet. A second conduit extends between the bottom of the annulus and an outlet at the wellhead. In operation, by producing fluid from the annulus and the second conduit outlets at the wellhead, formation fluid is induced to rise up the first conduit.  While the fluid rises, contained water flashes providing steam-enhanced lift. The now-cooled fluid flows out of the first conduit's outlet and into the annulus, separating into substantially gas-phase and liquid phase fluids which flow up and down the annulus respectively.  The gas phase fluid is produced from the top of the annulus.  Liquid-phase fluid pools in the bottom of the annulus may be artificially lifted through the second conduit using gas-lift or pumps for production at the wellhead outlet.

Title: Method of determining or detecting donor organ damage following xenotransplantation based on donor organ-derived analytes
Inventor: DOYLE JOHN MARTIN
IPC: G01N33/53
Filed: 1995-12-08
Abstract: A method of determining or detecting the presence of a donor organ-derived analyte in a biological fluid indicative of donor organ damage following xenotransplantation and, thereby, enabling identification of xenograft organ damage in a recipient comprises capturing said analyte by an antibody which is: a) specific for the donor organ-derived analyte; or b) capable of cross-reacting with said donor organ-derived analyte and directly or indirectly determining the donor organ-derived analyte. This method enables one to distinguish between host-derived and donor-derived analytes and, thereby, to obtain an indication of xenotransplant status and possibly rejection, so that corrective therapy can be undertaken as appropriate as soon as such a donor organ-derived analyte is identified. The method applies to in vivo and ex vivo xenotransplantation.

Abstract: In this method and with this device for the regulation of a drive, apart from an existing drive regulation (1) provided with subordinate rotational speed and torque regulation, a superimposed rapid rotational speed regulation (2) is provided for holding of the load after opening of the holding brake. In addition, computation of the load in a lift cage (5) is possible by means of a processing unit (3) with the aid of a target torque value (TMSOLL) and an actual rotational speed value (vist) Thereby, the drive can be so regulated with little material effort that jerk-free starting is made possible. Furthermore, appreciable cost savings result, since no additional hardware, such as load-measuring devices at the lift cage (5), is needed. Beyond that, the lift cage construction is simplified and expensive rebuilding of the cages during modernisation of lift installations becomes superfluous.

Title: Circuit for synchronizing picture and method therefor
Inventor: KIM SEONG-BONG
IPC: H04N21/44
Filed: 1998-08-04
Abstract: A picture decoding synchronizing circuit and a picture decoding synchronizing method are provided. When the decoding synchronization is controlled in units of a picture, in a variable length decoder using the transferred PTS and DTS information, the value obtained by adding the previous DTS to an offset is determined to be the DTS value of the current picture, if errors are generated in the transferred PTS and DTS, considering the errors of the transferred bit stream. If no errors are generated in the PTS or DTS, then the transferred PTS and DTS are determined to be the DTS value of the current picture. By controlling the picture decoding using the determined DTS value, the bit buffer does not underflow or overflow and the decoded data is displayed naturally on a screen.
