Abstract: In accordance with the present invention, an adjustable chimney cover is provided which can be adjusted in length and width to accommodate any size chimney. The chimney cover is comprised of a plurality of subassemblies, each of which comprises two side panels and a middle panel. The first ends of the side panels are movably mounted within a guide structure formed in the middle panel to allow the side panels to slide in first and second directions within the guide structure. The overall length of the subassemblies can be adjusted by sliding the panels in the first or second directions. Once the length of the subassemblies has been fixed, the side panels are locked in place. The subassemblies are then placed in an overlapping relationship and adjacent side panels are attached at their second ends. The second ends of the side panels are then attached to a chimney. In order to adjust the width of the chimney cover, additional side panels are used and/or the amount of overlap between the subassemblies is adjusted. Preferably, the second ends of adjacent side panels are attached by weaving a strap through slots formed in the second ends of the side panels and connecting the ends of the strap to a fastener which can adjusted to tighten the strap about the chimney.

Title: Method for applying a removable printed marking to a container
Inventor: STEENBERGEN JOHANNES FEMMINUS
IPC: B41F17/14
Filed: 1997-02-27
Abstract: For the application of a removable printing to a container, such as a plastic crate, a layer of ink, which forms the printing and is provided on one side with a bonding agent for bonding the layer of ink to the container, is transferred to the container from a carrier film to which the layer of ink has been applied to the side not provided with bonding agent. The bonding agent has such properties that in normal conditions of use of the container the layer of ink adheres firmly to the container and in predetermined conditions which differ from the conditions of use the bonding agent and the layer of ink are easy to remove from the container. This produces a container with a high-quality printing, which printing is easy to replace with another printing.

Patent CA-2250924-A1 (CA)
Title: Software pipelining a hyperblock loop
Inventor: CHANG POHUA
IPC: G06F9/45
Filed: 1997-03-13
Abstract: An iterative software pipelining method promotes instructions of a program loop to previous loop iterations and then reschedules the instructions until either 1) the resultant schedule is optimal (i.e. the initiation interval is equal to the minimum initiation interval) or 2) the resultant schedule is not an improvement over the previous schedule generated. The method is applicable to a sequence of instructions within a program loop having a single control flow entry and one or more control flow exit points. First, a minimum initiation interval of the program loop is computed (310). Second, instruction level parallelism transformations are applied on the program loop (335).  Third, a single iteration schedule is determined for the program loop (340).  Fourth, selected instructions are percolated to a prior iteration of the program loop to generate a new instruction order for the program loop (370).  Each of steps two through four is performed as long as a previous length of the program loop exceeds a single iteration schedule length (350) and the single iteration schedule length exceeds the minimum initiation interval (355).

Title: Tool holder
Inventor: MCGRATH RANDY C
IPC: B66F11/04
Filed: 1999-01-21
Abstract: Improvements in the field of tool holders are disclosed which address several shortcomings of the currently available products for use in attachment to a surface such as a truck bucket. For example, the addition of spacing legs of sufficient length to the rear surface of a tool holder allows for the angling of the open end of the tool holder towards the operator. A tool holder with pockets attached to it allows for the storage and retrieval of other items in addition to the main tool held by the tool holder. Finally, a tool holder with attachment rings disposed thereon allows for the attachment of a safety line or other item via a clip directly to the tool holder rather than elsewhere.

Patent CA-2262299-A1 (CA)
Inventor: SMITH WADE W
IPC: G01K17/06
Filed: 1999-02-18
Abstract: A system is disclosed for monitoring the use of water supplied by a pipe to a device that discharges water during use. A meter generates information indicating that water is flowing through the pipe with a measured BTU content and a control receives the information and determines that either the water is flowing through the pipe or that water has stopped flowing through the pipe. An event counter counts events defined by the flow of water through the pipe followed by the stoppage of water flow in the pipe for at least a predetermined duration of time, and a volume counter counts volumetric flow (gallons of flow, for example) and energy content (therms of energy, for example). Where the meter can be interfered with by attaching a magnet to the meter a tamper signal is also generated. With this data, misoperation of the devices can be indicated.

Title: Method for transferring credit from one gaming machine to another
Inventor: ACRES JOHN F
IPC: A63F/
Filed: 1999-04-27
Abstract: A method for transferring credits between gaming devices connected by a network to a host computer comprising. A player account accessible by the host computer is created. The player can access the account by inserting a card into a card reader at one of the gaming devices. A credit is applied by the player to the gaming device, typically by inserting bills into a bill acceptor. The credit and any awards resulting from gaming-device play are stored on a credit meter associated with the gaming device. Access to the account is terminated when the player withdraws the card from the card reader. A player initiates a request to redeem the balance stored on the credit meter by depressing a cash-out button.  The balance on the credit meter is transferred to the player account if the cash-out button is pressed before the card is withdrawn, and is paid to the player via the gaming machine if the button is pressed after the card is withdrawn.

Inventor: COOK GORDON JAMES
IPC: B07B/
Filed: 1998-02-25
Abstract: A method of constructing a frame for a filtering screen from a polymer material is described in which a wire frame reinforcement is wholly encapsulated during the frame moulding process so that two parallel spaced apart wires extend through each of the intersecting orthogonal ribs which define the open area of the frame across which the wirecloths are stretched. The surfaces of the frame in which the wirecloths are embedded are formed with ridges and the crests of the latter extend to different heights. The crests are softened by heating during the manufacturing process and the wirecloths stretched over the frame are forced into the softened crests after which the assembly is allowed to cool and cure. The frame is re-usable by stripping wirecloths from the top of the frame and fitting fresh wirecloths over the plastics material and heating the regions which are to encapsulate the fresh wirecloth.
