Patent CA-2000580-A1 (CA)
Title: Occult blood sampling device and assay
Inventor: FAN EUGENE
IPC: B01L3/00
Filed: 1989-10-12
Abstract: ABSTRACT      The invention provides a disposable device for collecting, transporting and storing semi-solid or liquid specimens prior to analysis.  A sample of the collected specimen is removed from the device for analysis by means of a detachable transferring stick, one area of which is the sample collecting portion of the device and another area of which is an integral handle.  The device also provides for the collection of a liquid sample drained from a defined volume of a semi-solid specimen through a porous screen and collected on the detachable transferring stick.  A sample of the specimen or liquid from it may be flushed from the stick for a qualitative or quantitative determination of analyte. The device is useful in collecting fecal specimens and detecting occult blood therein by a determination of hemoglobin in the specimen itself or in a liquid sample drained therefrom.

Title: Method for on-stream low-pressure regeneration of an oligomerization catalyst from a fluid-bed reactor operating at high pressure with hydrocarbons in a non-liquid phase
Inventor: HARANDI MOHSEN N
IPC: B01J29/90
Filed: 1989-12-13
Abstract: METHOD FOR ON-STREAM LOW-PRESSURE REGENERATION OF AN OLIGOMERIZATION CATALYST FROM A FLUID-BED REACTOR OPERATING AT      HIGH PRESSURE WITH HYDROCARBONS IN A NON-LIQUID PHASE                             ABSTRACT          A process is disclosed for stripping and regenerating a zeolite catalyst at relatively low pressure compared to that of an oligomerization reactor operated with a turbulent fluid-bed at above 515 kPa (60 psig). The reactor operates either with hydrocarbons in the gas phase, or, under near-critical or super-critical conditions, when they are in the super-dense phase. The super-dense phase exists outside a critical region in the phase envelope of the hydrocarbon mixture in the reactor, under conditions at which a liquid phase may not form (hence "non-liquid").  Whether the fluid-bed reactor is operated in the C5-C10 gasoline producing mode, the C+10 distillate mode, or, the C+22 lubes mode, continuous operation of a regenerator (for deactivated catalyst withdrawn from the reactor) at relatively low pressure, preferably less than 445 kPa (50 psig), is possible. A variable pressure "lock-stripper" recovers entrained hydrocarbon product from a recirculated catalyst stream before stripped catalyst is regenerated. As an alternative, a purging lock-hopper will step down the pressure and a stripper upstream of the regenerator and can strip the catalyst before it is regenerated. Without the lock-hoppers, attrition of the catalyst would make the process uneconomical. Regenerated catalyst is pressurized with feed in a charging lock-hopper downstream of the regenerator, and flowed to the reactor. The process results in oligomerization of a "light gas" or light naphtha, or other predominantly C3-C5 olefin feed, the remainder being mainly lower alkanes. Depending upon the process conditions, the oligomerized product is either C5-C10 gasoline, or a "heavies" stream (either distillate or lubes), with a minor proportion by weight of gasoline range hydrocarbons.

Title: Method and apparatus for moulding a fluid settable material
Inventor: WILLIAMS DAVID R
IPC: B29C39/40
Filed: 1990-02-08
Abstract: ABSTRACT OF THE INVENTION            A method and apparatus for moulding a fluid settable material.  The apparatus comprises male and female mould halves defining between them a mould cavity having an inlet thereto for the introduction of a fluid settable material; between the male and female mould halves of the cavity a seal can be interposed to seal the mould cavity from the atmosphere.  At least one vacuum outlet from a mould half leads via an isolation valve to a vacuum source.  The method comprises the steps of creating a depression in the mould cavity by withdrawing air therefrom through the vacuum outlet via the isolation valve, introducing a fluid settable material into the thus evacuated mould cavity until the mould cavity is wholly filled by the settable material, closing the isolation valve between the vacuum outlet and the vacuum source, injecting a small additional quantity of fluid settable material under pressure into the mould cavity, closing the inlet through which the fluid material is introduced into the mould cavity and allowing the fluid settable material to solidify.

Abstract: A method of consumable electrode arc welding is shown wherein the leading consumable electrode wire is mounted in parallel with a trailing filler wire, the latter inserted into a molten metal bath.  Welding current is divided between the consumable electrode wire and the filler wire.  These modifications improve the wettable boundary of the molten metal bath, prevent defects in the weld, and provide a high speed, highly efficient and high quality method of welding carbon steels, alloy steels, as well as aluminum and its alloys in a fully automatic as well as a semiautomatic operation.  In an apparatus utilizing the above method, a single torch contains the consumable electrode and filler wire.  One or more insulating contact tubes containing filler wire are mounted in a gas shield in parallel with a conductive contact tube containing consumable electrode wire.  The unit is small in size and light-weight, and thus convenient for a welder to carry or hold during operation.          Appropriate selection of one of the filler wires provided allows multidirectional operation without reorienting the torch.  The unit produces a high-quality weld at rapid welding rates and is suitable for automatic and semiautomatic operation.
