Patent CA-2105150-A1 (CA)
Title: Toy figure with spreading legs
Inventor: HESSE KURT
IPC: A63H3/46
Filed: 1993-08-30
Abstract: Abstract of the Disclosure:          A toy figure has a body of a downwardly open body shell.          Arms are attached to the body shell. A support member is inserted from below into and attached to the body shell. The support member carries legs. The legs are allowed to assume a spread-apart position by spreading the legs outwardly from a defined basic position. An inward biasing force is provided which restores the legs toward the defined basic position. The legs are thus automatically returned from the spread-apart position to the defined basic position.

Title: Methods of perforating a well using coiled tubing
Inventor: GEORGE KEVIN R
IPC: E21B23/04
Filed: 1994-10-06
Abstract: Abstract Of The Disclosure Methods of perforating a well using coiled tubing conveyed perforating guns are disclosed.   A perforating tool  string includes a coiled tubing string, a perforating gun, a releasable gun hanger, and a pressure responsive release connecting the coiled tubing string to the perforating gun.  The perforating tool string is lowered into place within the well and then the gun hanger is actuated by reciprocating motion of the coiled tubing string without rotating the coiled tubing string, thereby setting the gun hanger in the casing.  Fluid pressure is then increased in the coiled tubing string to actuate the pressure responsive release to release the coiled tubing string from the perforating  gun.    The  coiled  tubing  string  and  pressure responsive connector may then be retrieved from the well prior to  firing  the  perforating  gun.    The  perforating  gun  is subsequently fired by a pressure responsive firing head to perforate  the  well  casing,  and  the  perforating  gun  then automatically drops to the bottom of the well casing.

Abstract: A heating chamber for maintaining processed foods warm for extended periods while not sacrificing food quality or causing a secular change in the chamber's  insulating member.   The heating chamber has side walls formed by outer and inner walls made of relatively high heat conducting material, an insulating member  interposed  between  these  walls,  insulating  paper interposed between the insulating member and one side of the inner walls, insulating shield panels mounted on the opposite side of the inner walls,  each of the shield panels being a laminate of a second insulating member made of material such as styrene or urethane and a third insulating member made of material  such  as  polyethylene,  heater  guard  frames  each presenting a flattened U-shaped cross-section, and a ceramic panel heater mounted on the inner side of each heater guard frame, wherein each of the heater guard frames is mounted on the chamber's inner wall such that each encloses a shield panel while maintaining an air gap between the shield panel and its associated ceramic panel heater.  Heat emitted from the ceramic panel heater is transferred through the air gap,  the shield panel, the inner wall of the chamber, the insulating paper and to the insulating member so that a thermal affection on this insulating member may be effectively alleviated. The ceramic panel in each heater guard frame is divided, if desired, into a plurality of sections which are in a column, thereby allowing the temperature within the heating chamber to be maintained uniform.

Title: Anti-theft device
Inventor: FOSTER HAL
IPC: B60R25/06
Filed: 1995-04-05
Abstract: To reduce theft of manual transmission vehicles such as highway tractors, a device prevents movement of the gear shift lever. A mounting plate is attached to a vehicle floor and has a vertical bar welded to the plate and a hollow bar welded at an angle to the vertical bar. A sleeve engages a gear shift lever and a solid bar is attached to the sleeve. The solid bar is inserted into the hollow bar and both have holes which align to form a continuous hole when the two are inter-engaged with the lever in neutral position. A lock is inserted into the continuous hole, fastening the two bars together and immobilizing the gear shift. This reduces theft particularly by allowing the vehicle to be left unattended while the engine is running during a warm up period with the transmission in neutral.

Abstract: The amount of elemental sulfur or other sulfur contaminant picked-up by refined hydrocarbon product such as gasoline, diesel, jet fuel, kerosene or fuel additive such as ether, which is pipelined in a pipeline used to transport sour hydrocarbon fluids, is reduced by controlling the level of dissolved oxygen in the refinery hydrocarbon product to which is to be pipelined, said dissolved oxygen level being held to a level of about 30 wppm and less, preferably about 20 wppm and less.  The dissolved oxygen level in the refined hydrocarbon product is controlled by reducing the amount fair injection employed in mercaptan or disulfide reduction production increases or by the use of oxygen scavengers prior to the introduction of the refined hydrocarbon product into the pipeline, or by limiting the exposure of the product to air in oxygen during transport or storage.

Patent CA-2159511-A1 (CA)
Inventor: OGAWA TARO
IPC: F24F11/00
Filed: 1995-02-07
Abstract: An object of the present invention is to provide a simple, economical and safe driving device which is automatically activated by detecting solar light and an automatic ventilation system utilizing the aforementioned driving device. The electric motor (21) is connected to the 1-circuit 2-contact type relay switch (22), which is connected to the 1-circuit 2-contact type limit switch (23) and the 1-circuit 1-contact type light sensor switch (24). The limit switch (23) is connected between the relay switch (22) and the power supply and the manual main switch (25) between the light sensor switch (24) and the power supply. Normally when the main switch (25) is "on" and solar light exceeds the threshold of 35,000 lux, the light sensor detects it and the contact of the switch (24) changes from "a" to "b" to be activated. Electricity is then supplied to the relay switch (22) and the contact of the relay switch (22) also change "a" to "b" to be activated. If the contact of the limit switch (23) it at "b", electricity is supplied to the electric motor (21) to activate it. The electric motor is interlinked with the vent cover via the power transmission and the vent cover gradually begins to open. A specific time after the electric motor (21) is activated and the limit switch (23) comes in contact with the power transmission, then the limit switch's (23) contact changes from "b" to "a" to turn itself off. Thus the electric motor stops and the vent cover interlocked with the electric motor can stay open without operations of the manual switch. The main switch (25) normally stays in the "on" state, however, it can serve as a safety switch to forcibly shut down the system in the event of long-term shut down and maintenance.
