Patent CA-2304357-A1 (CA)
Title: Dispenser of rolled-up sheet materials
Inventor: HARMATHY TIBOR ZOLTAN
IPC: B65H35/10
Filed: 2000-04-10
Abstract: Device that enables a person to separate from a roll any length of flexible sheet material, typically toilet paper or paper kitchen towel. The moving parts of the device consist of a rotor, to which the roll is firmly attached, and an L-shaped braking arm that has a limited freedom of movement around a peg that can be added to any conventional roll-holding device. The free end of the roll is slid through a slit in one leg of the L. Directing the pull on the roll's free end up or down, the arm will bend slightly upward or downward. When bent upward, a smooth section of an opening in the other leg of the L becomes engaged with a section of the rotor consisting of a sprocket or gear (Variant A), or with a cylindrical surface of the rotor (Variant B), and thus the rotor/roll assembly is allowed to turn unimpeded under the effect of pull on the end of the roll. When bent downward, the sprocket or gear of the rotor becomes engaged with a protrusion in the same opening of the arm (Variant A), or the said cylindrical surface of the rotor becomes engaged with a braking surface in the same opening (Variant B), and thereby the rotor/roll assembly will stop turning. Increasing the pull, a piece of the roll outside slit will tear off.

Title: Tensioning unit
Inventor: FISCHER CHARLES
IPC: B65B13/22
Filed: 2000-05-02
Abstract: A tensioning unit 10 for a strapping machine serves for the tensioning and sealing of a band 18 guided around an item which is to be strapped. It has a tensioning head 20 and a housing 22 accommodating the same. The tensioning head 20 comprises a tensioning device 24 and a clamping and sealing subassembly 26.      Toward the end of a respective tensioning operation, it can be displaced relative to the housing 22 in a band-running direction B, which is counter to the tensioning direction S. Also provided in the housing 22 is a band guide 40 which is arranged downstream of the clamping and sealing member 26, as seen in the band-running direction B, and is subdivided into a front and a rear band-guide part 40' and 40", respectively. In this case, only the front band-guide part 40' can be displaced, together with the tensioning head 20, relative to the housing 22, whereas the rear band-guide part 40" can be moved away generally transversely to the band-running direction B by the front band-guide part 40', which is moved in the band-running direction B, preferably counter to a spring force.

Title: Latching solenoid valve
Inventor: WITT KEVIN
IPC: E03C1/05
Filed: 1998-10-26
Abstract: A pilot valve is operated by solenoid formed by a coil (52) wound around a non-magnetic spool that has a bore (56). A rare earth permanent magnet (62) is inside the bore adjacent one end and abuts a flux concentrator (58) farther inside the bore. A plunger (68) is slidably located within the bore biased away from the flux concentrator by a spring (70) and projects out another end of the bore. An enclosure of magnetic material completes a magnetic flux path around the solenoid and has an aperture through which the plunger projects. The pilot valve includes a cage (86) of rigid non-magnetic material which abuts the enclosure and has a recess which supports the plunger out of contact with the housing.      The plunger selectively opens and closes a pilot tube (92) through the cage to operate a diaphragm (100) that responds by engaging a primary valve seat to control the flow of fluid through a valve body.
Patent CA-2309566-A1 (CA)
Title: Clutch arm centering device
Inventor: DIMOPOULOS WILLIAM
IPC: F15B13/044
Filed: 2000-05-25
Abstract: A clutch arm centering device is disclosed. The device is mounted on a clutch using to operate piston valves on a crane or other heavy machine. The piston valves may be operated using a valve arm which has two operative positions and a neutral position between the two operative positions. A clutch arm of the clutch is linked to valve arm to allow the valve arm to be manipulated by a remote control coupled to the clutch. As parts of the linkage between the clutch arm and the valve arm wear, the centering device biases the clutch arm to a central position which corresponds to the neutral position of the valve arm, thereby avoiding problems of understroking and overstroking which arise in the prior art. One embodiment of the centering device employs a linear spring to ensure that the clutch arm does not sag due to gravity when the linkage wears. A second embodiment employs a helical spring which actively biases the clutch arm to its central position from two opposing directions. The second embodiment is suitable for use with a clutch mounted in any orientation.
