Title: Blocked slot clutch plate lining
Inventor: GUITAR GREGORY J
IPC: F16D13/74
Filed: 1997-12-08
Abstract: An automatic transmission clutch plate provides reduced drag in a wet clutch environment by employing independent offset slots through a friction lining applied to an annular clutch plate. The slots extend through the friction lining from at least one inner or outer peripheral edge of the ring to a terminating point between the radially inner and outer edges. In addition, slots through the friction lining extending from the radially inner edge are offset from the grooves extending through the lining from the radially outer edge. Preferably, the friction lining is formed by segments, and slots can be conveniently formed through the lining between radial edges spaced apart from each other on adjacent arcuate lining segments. In addition, the arcuate segments preferably include overlapping ends to form the offset slots.

Title: A method and system of accounting for transaction costs and currency exchange in a hybrid mail system
Inventor: LEVITSKY PAUL A
IPC: G07B17/00
Filed: 1997-12-22
Abstract: The invention is a method of accounting for a transaction cost and currency exchange relative to customer accounts in a hybrid mail system. The method begins by establishing a data center, a first remote data entry point, and a second remote data entry point which has mailpiece production means. The first remote data entry point, the second remote data entry point, and/or the data center may be co-located. A set of parameters which define a mailpiece, a unit cost where known for each parameter, a destination for the mailpiece, and a choice of debiting or crediting a customer account are determined at the first remote data entry point. The parameters and known costs point are transmitted to the data center and to the second remote data entry point. The mailpiece is produced at the second remote data entry point and a unit cost for each of the mailpiece production and delivery elements is calculated at the second remote data entry point and transmitted to the data center. A total unit cost of the transaction is calculated at the data center and then converted to a transaction cost by multiplying the total unit cost by a currency conversion factor. The transaction cost is then entered into customer account database, a transaction database, and transmitted to the first remote data entry point; additionally, a billing statement is generated by the data center in respect of the transaction and a similar statement can be generated by the first remote data entry point for the benefit of the transaction initiator.

Title: Braided composite prosthesis
Inventor: THOMPSON PAUL J
IPC: A61F2/90
Filed: 1996-08-12
Abstract: A prosthesis for transluminal implantation consists of a flexible tubular interbraided structure (18, 92, 100, 114) of metal or polymeric monofilaments (32, 94, 102, 112), and polymeric multifilament yarns (42, 108). The prosthesis can be elastically deformed to reduce its diameter through axial elongation. The monofilaments and multifilament yarns are arranged in axially spaced-apart helices, concentric on a common central axis of the prosthesis.  The monofilaments are selectively shaped before their interbraiding with the multifilament yarns, either by an age-hardening or other heat-setting stage, or a cold-working stage that controllably plastically deforms the strands. The shaped structural strands cooperate to impart to the prosthesis its nominal shape and resilience. The textile strands cooperate to provide a sheeting (40, 96, 104) that occupies interstices between adjacent structural strands, to reduce permeability and thereby enhance the utility of the prosthesis as a vascular graft. An alternative embodiment prosthesis includes elastically and plastically deformable structural strands, selectively plastically deformed by cold-working then interbraided to form the prosthesis.

IPC: H04B7/15
Filed: 1997-04-03
Abstract: In a time division mutiple access (TDMA) satellite radiotelephone communications system, a radiotelephone communicates random access channel radiotelephone communications signals to a satellite over a dedicated random access channel uplink carrier frequency band. In response, a time division mutiple access channel on a time division multiplexed uplink carrier frequency band different from the dedicated random access channel uplink carrier frequency band is assigned. The radiotelephone communicates time division multiplexed radiotelephone communications signals to the satellite over the allocated time division multiple access channel. Random access channel radiotelephone communications signals may be communicated to the satellite from a first radiotelephone over a first dedicated random access channel uplink carrier frequency band or from a second radiotelephone over a second dedicated random access channel uplink carrier frequency band different from said first dedicated random access channel uplink carrier frequency band. For a system in which the satellite communicates radiotelephone communications signals to radiotelephones located in a first coverage area and communicates radiotelephone communications signals to radiotelephones located in a second coverage area, random access channel radiotelephone communications signals may be communicated over a first dedicated random access uplink carrier frequency band if the radiotelephone is located in the first coverage area or communicating random access radiotelephone communications signals over a second dedicated random access channel uplimk carrier frequency band different from the first dedicated random access uplink carrier band if the radiotelephone is located in the second coverage area.

Filed: 1996-08-21
Abstract: A multi-purpose folding tool including a pair of folding scissors, in which a scissors blade is movable about a pivot shaft, between a stowed position and a deployed position in which a stop prevents the blade from moving further with respect to the handle because of pressure on the handle in the direction needed to close the scissors blades in a cutting stroke.  A rocker is moved by a spring in the tool handle and which in turn urges a movable scissors blade toward an open position. In one embodiment two handles are folded about respective scissors blades to house the blades, and four springs hold the handles together with the folded scissors stowed within the handles.  when the blades are deployed one of the springs holds each blade in position with respect to the handle while the other spring urges the blades toward an open position, through action of a rocker.  When the scissors and other tools are folded into their stowed positions in the handle of the multi-purpose tool of the invention the tool has a smooth outside configuration allowing the tool to be carried in a pocket without causing undue wear.
