Title: Method and apparatus for overlapping sheets in a sheet feeder and providing the overlapped sheets to a printing press
Inventor: SPELLER MICHAEL
IPC: B65H29/66
Filed: 2003-03-20
Granted: 2010-11-30
Abstract: The present invention is directed to a sheet feeding apparatus and method. In particular this invention comprises a sheet feeding apparatus having a first conveyance member (36), a second conveyance member (44), and a sheet bending member (26). The first conveyance member (36) conveys a sheet from a source of sheets at the first speed. The second conveyance member (44) is positioned near the first conveyance member, and conveys the sheets away from the first conveyance member at a second speed that is less than the first speed of the first conveyance member. The sheet bending member (26) is positioned to engage the sheet as the sheet moves from the first conveyance member to the second conveyance member. The sheet bending member engages the sheet to produce a gap between the tail end of the sheet and the second conveyance member. The lead edge of the next adjacent sheet from the first conveyance member is then fed into the gap. The apparatus also comprises a conveyance member for conveying a stream of overlapping sheets to the printing press. The conveyance member can have at least two portions pivotally connected to one another with at least one of the portions pivotally connected to the source of the stream of overlapping sheets. The conveyance member is constructed so that the portions can retract from the printing press in respect of pivotal connections.

Granted: 2011-10-11
Abstract: A dual-chamber type prefilled syringe comprises a cylindrical body within which a front plug member, a middle plug member and an end plug member are hermetically fitted to form a first chamber and a second chamber. The cylindrical body has an inner surface formed with a bypass. When the middle plug member moves to a position where the bypass is formed, the first chamber is communicated with the second chamber for the first time via the bypass. In this beginning state of liquid transfer (S), an inner volume (VS) of the cylindrical body between a leading end of the cylindrical body and a rear end of the front plug member is set to be at least 60% of a volume (VC) of a second component. When liquid component within the second chamber flows into the first chamber, it is possible to prevent part of the liquid component from passing through the first chamber to reach a portion for attaching an injection needle at a leading end of the cylindrical body.

Granted: 2010-06-29
Abstract: Disclosed are a method and a bar blade (10) for milling spiral bevel gears and hypoid gears. One end (14) of a shaft (12) of said bar blade (10) has a blade profile that is formed by the cross-section of at least one cutting area (24), at least two free areas (17, 19), and at least one top area (21). In order to create a tooth space, the blade profile is provided with a first cutting edge (16) for a first flank, a second cutting edge (18) for a second flank that faces the first flank, and a top cutting edge for the bottom of a tooth space.  The first and the second cutting edge (16, 18) are embodied as principal cutting edges for completely cutting the first or second flank. The top cutting edge (20) is configured for completely cutting the bottom of the tooth space such that the tooth space comprising the complete final geometry is created in one milling process by means of one and the same bar blade (10).  Due to the fact that the bar blade (10) performs the function of an external blade and an internal blade, the number of the cutting edges actively involved in creating a tooth space can be doubled while using the same milling head.

Granted: 2014-05-13
Abstract: A system is set forth that comprises a processor, such as a single processor or symmetric multiprocessor, and one or more memory storage units. The system also includes software code that is stored in the memory storage units. The software code is executable by the processor and comprises code for generating a plurality of adaptive partitions that are each associated with one or more software threads. Each of the adaptive partitions has a corresponding processor budget. The code also is executable to generate at least one sending thread and at least one receiving thread. The receiving thread responds to communications from the sending thread to execute one or more tasks corresponding to the communications. A scheduling system also forms at least part part of the code that is executable by the processor. In operation, the scheduling system selectively allocates the processor to each sending and receiving thread based, at least in part, on the processor budget of the adaptive partition associated with the respective thread. In this type of sending/receiving environment, the scheduling system bills the processor budget of the adaptive partition associated with the sending thread for processor allocation used by the receiving thread to respond to communications sent by the sending thread.

Title: Twisting wire actuator
Inventor: SHOHAM MOSHE
IPC: H01B/
Filed: 2004-10-24
Granted: 2014-10-14
Abstract: A twisted wire actuator, whereby the shortening of the length of a wire or a bundle of wires (20,21,22), as it is twisted, is used to control the motion of an actuated element, achieving sub-micron motion resolution. The control can be performed robotically. The high resolution can be achieved without the use of gears, sliders, or high precision lead screws, thus enabling a simplified actuation system and eliminating sources of friction. The use of wires (20,21,22) operating in opposing directions and having oppositely directed rotations significantly reduces the non-linearity effect inherent in twisted wire actuation, resulting in a system having a good level of motion linearity as a function of control input impulse. The use of multiple twisted wires (20,21,22) attached to the actuated element at different angles, enables the implementation of robotic systems with multiple degrees of freedom.  Several experimental actuators verify these results.
