Title: Improved oilfield tubular elevator and method for using same
Inventor: MOSING DONALD E
IPC: E21B19/06
Filed: 2000-09-28
Abstract: A U-shaped elevator (100) having no doors is provided with first and second latching mechanisms (102, 104) which when contacted by the tubular to be entrapped within the elevator (100) move from a closed position to an open position and which then return to a closed position as soon as the tubular is entrapped within the elevator (100). The latching mechanisms (102, 104) have a safety catch (120) which prevents the tubular from being inadvertently removed from the elevator (100).  The release of the safety latch mechanism (120) can only be activated by a handle (170) which is manipulated by hand by personnel working on the derrick utilizing the elevator (100).

Title: Bit stream separating and merging system, apparatus, method and computer program product
Inventor: TOMINAGA HIDEYOSHI
IPC: H04N7/50
Filed: 2001-11-23
Abstract: Herein disclosed is a multiple-output bit stream separating apparatus for inputting an original MPEG-2 bit stream to separate into a plurality of transcoded MPEG-2 bit streams and a plurality of differential bit streams, and a multiple-output bit stream merging apparatus for inputting the transcoded MPEG-2 bit stream and the differential bit streams to reconstruct the original MPEG-2 bit stream. The bit rate of the transcoded MPEG-2 bit stream and the differential bit streams thus multiple times separated are much lower than that of the original MPEG-2 bit stream. This leads to the fact that the multiple-output bit stream separating apparatus and the multiple-input bit stream merging apparatus can promptly and reliably transmit and receive an original MPEG-2 bit stream having a large bit rate by transmitting and receiving a plurality of transcoded MPEG- 2 bit streams and a plurality of differential bit streams in place of the original MPEG-2 bit stream.

Patent CA-2367255-A1 (CA)
Title: Dry foodstuff dispenser
Inventor: WALDMAN HAROLD
IPC: A47F1/03
Filed: 2002-01-08
Abstract: A dispenser for storing and dispensing dry foodstuffs includes a hopper and a free flow ball-type dispensing mechanism. The hopper chamber is configured for store shelf use having planar front and side panels. An exit orifice is formed in a lower portion of the hopper and most preferably at a lower front portion. The dispensing mechanism is positioned over the exit orifice and is selectively operable to regulate the dispensation of foodstuffs to the consumer. The dispensing mechanism is characterized by a covering housing and an internal gate mechanism. The covering housing includes a generally semi-spherical portion with an opening therethrough and an anchoring flange. The covering housing is secured over the hopper exit orifice such that foodstuffs move downwardly from the hopper chamber under gravity, through the exit orifice and into the interior of the semi-spherical portion of the covering housing. The gate member is selectively movable relative to the semi-spherical portion between a position where it substantially overlies and blocks an outlet opening in the semi-spherical portion to prevent movement of foodstuffs therethrough, and an open position wherein the gate member is moved at least in part therefrom, permitting the free flow of foodstuffs from the interior of the covering housing outwardly through the opening. A handle secured to the gate member projects outwardly through a slot formed through the covering housing where it may be grasped by a user, and wherein the slot extends in a plane which is generally perpendicular to the lateral width of the hopper to which the ball dispenser is mounted.
Patent CA-2368180-A1 (CA)
Inventor: YOUNG RAYMOND A
IPC: A01C1/08
Filed: 2000-06-23
Abstract: Living matter such as seeds are treated by exposing the living matter to a cold plasma to form a plasma reacted deposit on the surfaces of the living matter. Plasma treatment can be carried out under conditions that do not significantly affect the viability of live seeds and other appropriate livin g matter, and can be carried out to maintain the moisture level within the see ds or even reduce moisture during the treatment process. In carrying out the process, gas is provided from a gas source from which the deposit may be formed by a plasma reaction. A cold plasma is ignited in the gas and the material is exposed to the plasma for a selected period of time to form a plasma reacted deposit on the exposed surfaces. The living material may be tumbled while exposed to the plasma process to allow the deposit to be forme d uniformly on the surfaces of the living matter.
Patent CA-2370364-A1 (CA)
Title: Sunscreen composition containing sol-gel microcapsules
Inventor: SERI-LEVY ALON
IPC: A61K8/44
Filed: 2000-05-24
Abstract: The present invention generally relates to safe and stable sunscreen compositions comprising at least one sunscreen active ingredient in the form of an inert sol-gel microcapsules encapsulating ultraviolet absorbing compounds in any acceptable cosmetic vehicle. The composition according to the present invention can comprise several ultraviolet absorbers that may be encapsulated in the same sol-gel microcapsule or in different capsules. The encapsulation of the ultraviolet absorbers reduces or even prevents the contact between the sunscreen compounds and the human tissue, thus reducing various adverse effects that are associated with the use of sunscreens. The encapsulation also reduces or even prevents cross reactivity between the suscreen compounds and the packaging material and between the suscreen compounds and any other component present in the composition, thus enhancing the compositions stability. The hydophobicity/hydrophilicity character of the sol-gel microcapsules can be controlled by selecting suitable sol-gel precursors and suitable reaction conditions and can be chosen to be compatible with the cosmetic vehicle to be used in the sunscreen composition. The sunscreen compositions of the present invention can comprise any acceptable UVA and/or UVB absorbing compounds at any desired ratio to obtain a desired accumulative ultraviolet screening spectrum.

Patent CA-2383468-A1 (CA)
Inventor: JABLONKA DAVID ANDREW
IPC: C23C10/28
Filed: 2002-04-25
Abstract: A method for applying diffusion aluminide coating on a selective area of a turbine engine component and the coating produced by that method is disclosed. A  quartz infrared lamp heats only substantially the localized area of the component to be coated, rather than the complete part. Either halide activated or non-activated tape (20) is applied on the area to be coated and is held in place during coating using a high temperature dimensionally stable tape holder (30) manufactured from graphite or ceramic. The quartz infrared lamp is used to heat only the desired area to a coating temperature of about 1800° F. to about 2000° F. under an inert atmosphere for about 3 to about 8 hours to achieve the desired aluminide coating thickness. No powder masking of the machined surface area is required. Due to the localized heating, aluminum vapor generated from the tape will only deposit aluminide coating on the taped area.
