Inventor: SCHUELE OTTO
IPC: B25G3/10
Filed: 1995-02-17
Abstract: A threaded connector is disclosed for attaching a handle to a tool head, such as a rake or a broom. The threaded connector may include a central cap or plug and a plurality of opposed wings extending radially outwardly therefrom. The wings are in the form of hollow partial cylinders and are hingeably attached to the cap. The cap is positioned on the end of the handle and the wings are folded downwardly and inwardly to engage the handle. Each wing includes partial thread segments that register to form a full thread when the wings are folded together. The full thread has a shallow taper such that tightening of the connector within a mating socket in a tool head causes the connector to bind or wedge itself into the socket. To provide additional resistance to loosening a locking ring has longitudinal mortices which key into aligned rabbets in the connector and in the socket.

Title: Daisywheel convector plate for batch coil annealing furnace
Inventor: HEMSATH KLAUS H
IPC: C21D9/67
Filed: 1995-06-29
Abstract: An improved convector plate is provided for a batch coil annealing furnace.  The plate includes a top annular plate, an identical bottom annular plate and an annular diverter plate in between.  A plurality of slotted openings are provided in the top and bottom plates which extend radially outwardly from a first imaginary circle spaced from the inner peripheral edge of the top and bottom plates to an imaginary second circle spaced  inwardly  from  the  top  and  bottom  plate's  outer peripheral  edge.

Patent CA-2162745-A1 (CA)
Title: Perforated rolled paper or nonwoven products with variable bonded length and method of manufacturing
Inventor: JONES RICHARD EVAN
IPC: B65H18/28
Filed: 1995-11-14
Abstract: Improved detaching of perforated roll products of paper or nonwovens is achieved by selectively reducing strength of the sheet along the perforation line at the edges of the sheet. This is achieved by lowering the bonded length (the sum total of the distance between perforations) at the edges of the sheet relative to that within the central portion of the sheets. Greater bonded lengths in the middle of the sheet enable the sheet to pass through converting operations with minimal breaks, while having lower bonded lengths at the outer edges allows the user more easily to start a tear in the sheet at the perforation and to reduce the number of "ears" left on the roll as a result of detaching.

Patent CA-2171059-A1 (CA)
Inventor: REICHLER ALLEN S
IPC: B01L3/00
Filed: 1996-03-05
Abstract: An apparatus for containing a liquid biological sample and for performing a biological process thereon comprises a sample area for receiving the sample, at least one reaction area in fluid communication with the sample area, a pneumaticarea in pneumatic communication with the reaction area and the sample area, and a pneumatic port in the pneumatic area for connection of the apparatus to a pneumatic aspiration/dispensing means. The pneumatic aspiration/dispensing means provides for controlled flow of the liquid biological sample between the sample area and the reaction area. To reduce evaporative loss of the sample fromthe apparatus, a sample tower is provided in fluid communication with the sample area. A similar tower may be provided at the pneumatic port to reduce evaporative loss through the pneumatic area. A restricted orifice between the sample tower and the sample area holds the liquid sample in place during removal of the sample from the apparatus, counteracting the tendency of the liquid bolus to flow back toward the reaction area due to capillary forces. Alsodisclosed is a novel sealing arrangement which provides an effective pneumatic seal between the pneumatic port and a pneumatic aspiration/dispensing means without requiring the apparatus to include a separate "O" ring or other type of discrete sealing device.

Abstract: A multi-lumen enteral feeding and medicating device having a gastric tube adapted to be introduced into the interior of a patient's stomach through a stoma.  The gastric tube has a balloon to engage and seal against the interior wall of the stomach around the stoma and a locking ring to engage the skin of the patient surrounding the exterior opening of the stoma. A jejunal tube is slidably engaged in the gastric tube for relative longitudinal sliding displacement so that the distal end of the jejunal tube may be threaded through the stomach into the jejunum for introduction of a fluent material through ports adjacent the distal end of the jejunal lumen.  A fluid lumen is provided in the gastric tube for applying positive and negative pressure to the interior of the balloon to extend and retract the same and an inlet attachment is provided for accessing the gastric lumen for introducing fluent material into the stomach through the gastric lumen. The jejunal tube passes through the gastric lumen and out through the inlet attachment.  A sealing plug is provided to seal the inlet to the gastric lumen at the point where the jejunal tube exits the gastric lumen. The sealing plug operates to anchor the jejunal tube within the gastric lumen at the desired location which positions the distal end of the jejunal tube within the jejunum.
