Patent CA-2272726-A1 (CA)
Inventor: CHOSHI YUKIHISA
IPC: B22D17/30
Filed: 1999-05-25
Abstract: An automatic molten metal supply and injection device which can prevent mixing of air into molten metal while being supplied, which can reduce the possibility of explosion and the development of pores, and which makes it possible to supply molten metal irrespective of whether the molds are opened or closed. The device includes a body for guiding molten metal, a sleeve having a suction port and a discharge port for opening and closing communication between a molten metal passage of the body and the suction port, a first piston axially movably mounted in the sleeve for sucking molten metal in the sleeve in a predetermined amount through the suction port and extruding the thus sucked molten metal through the discharge port, and a second piston axially movably mounted in the first piston for opening and closing the discharge port and for pressurizing molten metal being discharged through the discharge port. The first and second pistons are movable independently of each other.      Thus, it is possible to prevent mixing of air into molten metal being supplied into the molds.
Patent CA-2272779-A1 (CA)
Inventor: STAHL KERMIT E
IPC: E04D1/26
Filed: 1999-05-28
Abstract: This invention is directed to a multi-layer laminated shingle, wherein each shingle layer comprises granule and bituminous coated web, with the layers laminated together and with the butt zone of the base layer disposed against a bottom surface of the tab zone of the secondary layer and with the tab zone of the base layer disposed against the bottom surface of the butt zone of the secondary layer. The shingle lends itself to having tabs spaced by voids. Because the tabs in the base layer are inverted, the base layer's butt zone is visible through voids in the tabs of the secondary layer.      The method of making the shingle lends itself to complementally cutting out the tabs of two side-by-side shingles from a given line. Enhanced nailing area is provided, and stacking of shingles for packaging is facilitated.

Title: Scored u-shaped packaging members
Inventor: LOESCHEN MICHAEL D
IPC: B65D81/113
Filed: 1999-06-25
Abstract: A packaging member comprises a base member and a pair of side members hingedly attached to opposite sides of the base member such that the side members can be alternatively and selectively disposed in two different positions with respect to the base member. In particular, the side members can be dispos- ed perpendicular to the base member, or alternatively the side members can be disposed at predetermined angled positions with respect to the base member. When disposed perpendicularly to the base member, the packaging member has a substantially U- shaped configuration enabling the packaging member to serve as an edge protector, whereas when the side members are disposed at their angled positions with respect to the.base member, the packaging member has a substantially trapezoidal configuration enabling stacking or nesting of the packaging member along with other similar packaging members so as to optimize storage, shipping, and handling or transportation costs.

Title: Total release actuator for an aerosol can
Inventor: DEMAREST SCOTT W
IPC: B65D83/16
Filed: 1998-05-11
Abstract: A total release actuator for use with an aerosol can having a chime (18), a dome (16), and a valve (24) having a valve stem (26).      The actuator has an actuator body (28) with a lower margin defining a skirt rim (32) that attaches to the aerosol can and a central well (36) having a generally horizontal well floor that has a trigger port extending therethrough. The actuator has a trigger (48) that is hingedly attached to the actuator body, preferably at its front end (56) to the front end of the trigger port. The trigger swings downwardly when it is depressed. The trigger extends across the valve stem and includes a downwardly open stem socket (58) that receives the valve stem. The stem socket communicates with a discharge nozzle (60). The trigger, when moved downwardly, activates the valve, releasing the contents of the can through the discharge nozzle via the stem socket. A latch (62) is attached to preferably each side of the trigger port, extending laterally under the trigger. The latch is elastically deformable, allowing the trigger to pass as it is depressed downwardly and then springing back over the trigger to retain it in the depressed, valve-activating position, allowing can contents to discharge. By this means, a user can release the entire contents of the aerosol can without the user's having to continue to depress the trigger. A method is described of discharging the contents of an aerosol can by use of such an actuator.

Title: A process for the simplified biological rehabilitation of land polluted with long-term contamination based on mineral oil
Inventor: LAUER URSULA
IPC: B09C1/10
Filed: 1998-08-29
Abstract: The invention relates to a simplified method for biologically cleaning almost any-sized area of soil which is contaminated with mineral oil-based hydrocarbons (MHC), and especially the leftover pollutants associated with mineral oil-based hydrocarbons. According to said method, the contaminated soil is treated with concentrated nutrients to stimulate and help the growth of MHC-consuming micro-organisms so that they can be cultivated and reproduce more quickly. The inventive method is characterised in that it is particularly easy to carry out and in that after a) advance dampening/watering if necessary, b1) the soil being cleaned is broken up to a considerable depth in at least one process, b2) the concentrated nutrients are added in the form of an aqueously dilute emulsion and/or dispersion, said concentrates being sprayed essentially evenly, also in at least one process, and c) the soil is then thoroughly re-watered. Steps b1) and b2) can be carried out once or repeatedly. The following sequences are preferable: (b1)(b2); (b2)(b1);  (b1)(b2)(b1) or (b2)(b1)(b2).
