Patent CA-2351906-A1 (CA)
Inventor: BRASZ BEN J
IPC: B62B1/26
Filed: 2001-06-28
Abstract: A manual wheeled hand cart designed to hang flexible bags of assorted items.  Six precise located hooks suspend overlapping bags on a wire frame grid upright back, with a single handle. The upright has two different vertical angles to position and stabilize the bags which once located remain in their original position and don't shift while being transported. The upright frame back is fixed two inches ahead of the wheels providing a zero weight balance on the handle while in transit. This condition on the handle is equal for a five or six foot tall person. The wire grid base comes in three styles, fixed base, fold up base and removable base. The wheels are attached to the wire frame base for the fixed base model. The two wheels on all three models are mounted under and inside avoiding contact with the load or any hanging objects.

Patent CA-2357085-A1 (CA)
Title: Cache update method and cache update control system employing non-blocking type cache
Inventor: YAMASHIROYA ATSUSHI
IPC: G06F12/08
Filed: 2001-09-06
Abstract: If a cache miss occurs at a time of a load request from a processor core, an issuance check block (20) issues a request of reading out data caused by the cache miss, to a main memory from an issuance control circuit (50), and then registers the information of the request in a request buffer circuit (30). A cache block (10) does not update an address array (12) at that time, and it is processed as a cache hit if a following instruction is hit to an address stored in an entry of an update schedule. The update of the address array (12) is done simultaneously with the update of a data array (11) when responsive data is received from the main memory with regard to said request. Accordingly, it is possible to provide a new cache update method, in which the feature of a cache of a non-blocking type can be sufficiently used, such as the merit of continuing a process for a following instruction even while the request of reading out the data caused by the cache miss is sent to the main memory.

Title: High volume portable concrete batching and mixing plant having compulsory mixer with overlying supported silo
Inventor: GUNTERT RONALD M JR
IPC: B28C9/04
Filed: 2001-09-19
Abstract: A first mixer trailer forms the plant frame foundation around a twelve-yard compulsory mixer. The compulsory mixer is mounted for elevation relative to plant frame foundation by hydraulic lifting columns. In system erection, a cement silo trailer is first mounted to the top of the compulsory mixer when the compulsory mixer is at ground level. Thereafter, both the mounted silo and the compulsory mixer are raised and pinned in place by the hydraulic lifting columns so that gravitational discharge of mixed concrete can occur directly from the compulsory mixer to an underlying transporting apparatus, usually a truck.

IPC: B24B49/16
Filed: 2001-12-21
Abstract: A grinding method for single-disc cylindrical grinding of elongated objects, such as cylindrical paper ma-chine rollers, in which method the ob-ject to be ground is rotated about its axis and a grinding stone is rotated and its position on the surface of the ob-ject being ground is adjusted so that the grinding point of the grinding stone is held substantially at a constant dis-tance from the center axis of the object being ground regardless of the deflec-tion of the object. In the method, the position of the grinding stone is ad-justed by means of an oscillating posi-tioning controller synchronized with the rotation of the roller and receiving feedback from a measured quantity that bears a linear correlation to the change of position of the surface being ground.
