Title: Parking lock with secondary brake
Inventor: ALBRIGHT LARRY E
IPC: B60T11/04
Filed: 1998-05-12
Abstract: A parking lock for a vehicle such as a skid steer loader is designed to provide a positive lock of drive elements when certain conditions are present on the loader, such as the absence of an operator on an operator seat or the movement of an operator restraint to  its non restraining position.   The  lock member comprises a disc on a final drive axle,  that has a member that engages lugs on the disc to provide the locking function, and a friction brake manually operable to engage the discs to reduce the speed of rotation of the discs.   The discs having lugs thereon formed in relation to the forces urging lock member toward the discs, such that the lock member will ride on the outer periphery of the disc until the speed has been reduced to a selected amount generally by operation of the brake.

Patent CA-2240273-A1 (CA)
Inventor: MORTON ROSS
IPC: E06B7/26
Filed: 1998-06-10
Abstract: A method of preventing water leaking from a window frame from damaging a building includes installing flashing under the window without removing the window. The method includes cutting a passage sloping upwardly from the outside surface of the wall just below the window. A flashing member is inserted into the passage, along the entire length of the window. The interior edge of the flashing extends beyond the interior surface of the window frame. Water leaking from the frame is directed outwardly by the flashing. The interior edge of the flashing preferably has a lip which .may be used to fasten the flashing to the interior surface of the window frame. This secures the flashing member in the passage. The method is much less expensive than the alternative of removing and replacing windows which have leaking frames.

Patent CA-2266646-A1 (CA)
Inventor: GALLAGHER TERENCE J
IPC: B44C1/17
Filed: 1997-09-17
Abstract: A technique and machine for transferring discrete areas of material, such as hot stamping foil (F), from a carrier onto positions spaced apart along a substrate (5), such as paper. The carrier is dispensed at a rate that is much less than the speed of movement of the substrate. During transfer, a segment of the carrier is moved at the same speed as the substrate while, in between such material transfers, the speed of the carrier is sharply reduced and even reversed in direction in order to maintain the average speed of this carrier segment equal to the reduced speed at which the carrier is being dispensed. This is accomplished by a shuttle mechanism (18) that is moved by its own motor, under control of a microprocessor-based motor control system, in synchronism with the speed of the substrate and transfer operations. This significantly improves the utilization of the material on the carrier, with an improved flexibility to adapt to various substrate speeds and ease of implementation in machinery.
