Title: Stationary exercise support for a wheelchair
Inventor: KLEINSASSER JONATHAN
IPC: A63B71/00
Filed: 1997-01-31
Abstract: A stationary exercise support apparatus for a wheelchair comprises a frame with a pair of horizontal rollers across the frame onto which the wheelchair can be rolled to sit cradled between the rollers. Rotation of the rear wheels of the wheel chair thus drive the rollers while the wheel chair remains stationary on the frame. The wheelchair is held in place by a pair of guide wheels mounted inside the rear wheels of the wheelchair on a support plate behind the rear roller so that the wheelchair is prevented from side to side movement. The wheelchair is held against forward movement of the cradling rollers by a third roller positioned forwardly of the front roller which can be raised and lowered by a handle at one side to a lowered position in a common horizontal plane with the first two rollers in which the wheelchair can roll off the cradled position to a raised position preventing forward movement of the wheelchair.

Title: Workpiece descaling process
Inventor: SCHWEIGHOFER ANDREAS
IPC: B21B45/08
Filed: 1997-01-29
Abstract: In a process for descaling a workpiece (22), in particular rolling stock, the workpiece is moved past rotary descaling means, and at least one liquid jet which rotates around an axis of rotation that crosses the surface (23) to be descaled of the workpiece (22) is projected onto the surface (23) to be descaled.

Patent CA-2252012-A1 (CA)
Title: Improved apparatus and method of providing a mobile communication system
Inventor: DUPLESSIS PHILIPPE
IPC: H04W16/32
Filed: 1998-10-16
Abstract: The present invention provides a mobile radio telephone system (10, 15) and a method of operating it in which the beacon frequency is at least temporarily transmitted in a discontinuous manner. This allows a base transceiver station (2, 4, 6, 16, 20, 22) to make use of the gained time for either transmitting on another frequency or monitoring neighboring radio frequency sources for potential interference. In a particular embodiment of the present invention, the beacon frequency is interrupted by connecting the transmission path to the receiver path within the base transceiver station (2, 4, 6, 16, 20, 22). This may be done by single pole double throw high frequency switches. The interruption may be temporary or may applied permanently. Further, in a system in which all transmissions by the base transceiver stations (2, 4, 6, 16, 20, 22) are synchronized, mobile stations (12) are described which are adapted to measure signal strength depending upon the duty cycle of the beacon frequency.

Abstract: An acoustical barrier (10) for a vehicle having a barrier wall which includes a floor area (23) and a fire wall area (25) extending between a wheel well area (41) and a drive train area (42). The acoustical barrier (10) includes a mass layer (12) that covers at least a portion of the barrier wall.      The mass layer (12) has an inner surface (16) that faces the barrier wall with an integrally formed peripheral rib (52) projecting therefrom. A first set of elongate ribs (48) intersects and joins with a second set of elongate ribs (50).   The first and second sets of elongate ribs (48, 50) are located within the enclosed area. Each elongate rib (48, 50) includes an upper portion integrally formed with the inner surface (16) of the mass layer and a lower portion with an outer edge (54, 60) adapted to at least face the barrier wall. Each elongate rib (48) of the first set of ribs also has opposite ends integrally formed with the peripheral rib (52) to thereby strengthen the peripheral rib against bending moments due to compression forces applied to the outer surface of the mass layer. Each elongate rib (50) of the second set of ribs has opposite ends integrally formed with either adjacent ribs (48) of the first set of ribs or the peripheral rib (52) and an adjacent rib (48) of the first set of ribs to thereby further strengthen the peripheral rib (52) against bending moments. The first set of ribs projects from the inner surface of the mass layer a greater distance than the second set of ribs to provide increasing levels of impact resistance to the outer surface of the mass layer.

Title: Gas trap for drilling mud
Inventor: ZAMFES KOSTA
IPC: E21B21/06
Filed: 1999-04-30
Abstract: A gas trap is provided for liberating subterranean gases entrained in drilling muds. The trap comprises a pair of opposing truncated right circular vessels and having a concentric bottom mud inlet, a side mud outlet and a gas outlet at the top. A hollow shaft stirrer depends vertically and concentrically within the trap and has radial tubes extending from its lower end for forming a continuous bore within the shaft. The radial tube ends are bevelled on the trailing edge. Ports are formed at the top of the hollows shaft. The trap is partially immersed in mud forming a mud level in the trap and a freeboard area above containing air. When rotated, the hollow shaft spins the mud forming a turbulent low pressure area at the bevels, drawing air down the shaft from the upper ports and injecting air into the mud, all of which aids in liberating gases from the mud.

Title: Liquid level control in an acoustic droplet emitter
Inventor: ROY JOY
IPC: B41J2/015

Abstract: An acoustic droplet emitter which a liquid level control plate has a lip in intimate contact with the free surface of a liquid is constructed. The liquid level control plate also has an effective aperture diameter at the exit edge of the plate which is larger than the effective aperture diameter at the lip. This reduces the pressure sensitivity of the free surface of the liquid and allows for the free surface of the liquid to be effectively pinned at the bottom surface of liquid level control plate for wider variations in pressure than using conventional methods.
