Title: Central hubs for flexible magnetic data discs formed of magnetically soft polyacetal compositions
Inventor: HUGHES PATRICK M
IPC: G11B23/03
Filed: 1992-03-24
Granted: 2002-02-12
Abstract: Flexible sheet-like magnetic discs (so-called "floppy discs") are provided with a central hub formed of a magnetically soft polyacetal composition. The polyacetal composition necessarily includes a polyacetal resin and elemental iron particles homogeneously dispersed throughout the polyacetal resin in an amount sufficient to impart the desired soft magnetic properties to the inherently nonmagnetic polyacetal bane resin. The polyacetal compositions of this invention are infection-moldable so that central hubs for flexible magnetic discs can be rapidly and economically produced.

Title: Jejunocath and surgical pad
Inventor: BOMMARITO ALEXANDER A
IPC: A61M25/04
Filed: 1992-04-21
Granted: 1995-01-03
Abstract: ABSTRACT           The present invention provides a Jejunocath comprising a novel removable surgical fixed pad adapted to be fastened to the bowel wall and to the anterior abdominal wall, thereby holding the catheter in place and preventing leaking from the bowel into the peritoneal cavity.  The invention also provides a unique adapter that inhibits catheter blockage of undissolved medications and feeding formulas, provides for ease of removal of trapped undissolved matter in the adapter and for high adhesion in the connection between the adapter and catheter, thereby preventing leaks and unintended removal of a universal "Y" port from the catheter.

Title: Enthalpy control for co2 refrigeration system
Inventor: MARTIN PATRICK S
IPC: F25D29/00
Filed: 1991-08-08
Granted: 2002-04-02
Abstract: A method and appara-tus to refrigerate air in a com-partment wherein liquid CO2 is delivered through a first primary heat exchanger (201) such that sufficient heat is ab-sorbed to evaporate the liquid carbon dioxide to form pres-surized vapor. The pressur-ized vapor is heated in a gas fired heater (207) to prevent solidification of the pressur-ized carbon dioxide when it is depressurized to provide is-entropic expansion of the va-por through pneumatically driven fan motors (294, 295) into a secondary hoot ex-changer (250). Orifices (294b, 295b) in inlets to the fan mo-tors and solenoid valves (222, 224) in flow lines to the fan motors keep the vapor pres-surized while the heater sup-plies sufficient heat to pre-vent solidification when the CO2 vapor expands through the motors. CO2 vapor is routed from the second heat exchanger to chill surfaces in a dehumidifier to condense moisture from a stream of air before it flows to the heat exchangers.

Abstract: A roll which has a metallic core and an elastomeric envelope is obtained by assembling the envelope from a stack of discs each of which surrounds the core.  In order to impart to the envelope a desired elasticity, the discs contain a fibrous material and a plastic substance and are pressed against each other in the longitudinal direction of the core.  The plastic substance is hardenable within an interval exceeding 48 hours.  The pressing step is started with a delay following the step of placing the discs around the core such that the hardening begins prior to compressing and is terminated within an interval not less than 48 hours following the start of the pressing step.

Abstract: A rack for electronic equipment based on modules of predetermined size comprises a pair of vertical structural members (3) positioned to receive and support card-frames (22) of predetermined dimensions in a vertical array between them and to support cables (32) to be connected to electronic equipment to be mounted in one or more of the said card-frames. The structural members (3) are shaped to define vertically extending cabling spaces (4) which are open and free of fixed obstructions over at least a major part (or major parts) of the height of the cabling spaces (a) outwardly to respective sides of the module over at least a major part of its depth; and (b) towards the front of the module adjacent to its side.      The openings to the sides of the module allow two such racks to be mounted in a conventional side-to-side position, Without mounting side panels or partitions between them, so that the adjoining cabling spaces of the two racks come together to create a common cabling space of double width; in the case of a rack to ETSI dimensions this means a common cabling space wide enough to get a hand in, and in every case it means that cables can if required be positioned along the module boundary.      The opening to the front of the module allows cables to be inserted (and removed, if required) from the front of the apparatus, whether or not card-frames and equipment are in place or in service.

Abstract: A system that allows a calling party to quickly select a call coverage system to be utilized if a call is unanswered. The calling party can preselect the call coverage before the call is placed, and the called telephone terminal automatically transfers the call to the selected call coverage service if the called party does not answer. Alternatively, the called telephone terminal transmits back the available call coverage options if the incoming call is not answered. In response, the calling telephone terminal displays the available call coverage options to the caller, and the caller selects the call coverage option desired. The calling telephone terminal then transmits the selected call coverage option to the called telephone terminal which transfers the call to the selected call coverage service. Also, when the caller wants only to leave a message on a particular call coverage system and not talk to thecalled party, the caller preselects the call coverage option and requests to only leave a message for the calling telephone terminal (call coverage only). Upon receiving a message defining call coverage only, the called telephone terminal immediately transfers the call to the selected call coverage system.

Title: Weed or vegetation removing tool
Inventor: LU YUAN-HAI
IPC: A01B1/16
Filed: 1994-01-21
Granted: 1997-11-18
Abstract: A weed or vegetation removing device somewhat resembling a walking stick is provided and enables weeds to be removed manually from a standing position without having to be handled. It includes a fork that has at least two mutually inclined co-acting tines, an operating handle, a set of lazy tongs and a rigid spacing member. The latter extends between the handle and the set of lazy tongs, the latter including a first pair of mutually pivoted links, the lower one of which has mounted thereon at least one of the tines, and a second pair of mutually pivoted links, the lower one of which has mounted thereon at least one of the other of the tines.  An actuating member associated with the handle end of the rigid spacing member is adapted to actuate remote release means which temporarily disengage locking means disposed on the lower link.  The tines are adapted, in response to a reactive ground-imparted force to be locked in substantially parallel alignment until released in response to actuation of the actuating member, thus causing a weed to be seized and retained between the tines during the resulting mutual inclination of the tines as the tool is lifted from ground level by the handle.

Abstract: An intra-luminal expander assembly for use with a catheter comprises an expandable tubular expander element having openings, for example slots, formed in it, and first and second fixation portions located at or towards its ends. The expander element is disposed around a core element which comprises a shape memory alloy which has been treated so that, when the temperature of the alloy is increased above its A S temperature, it displays a shape memory effect and the length of the core element decreases. The expander element is attached to the core element through the first fixation portion and oriented so that, as the core element decreases when its temperature increases, the first fixation portion is caused to move relative to the second fixation portion in a direction towards the second fixation portion, and the second fixation portion being restrained against movement with the first fixation portion so that the length of the expander element decreases and its transverse dimension increases.
