Title: Tubular Core Assembly for Winding Paper and Other Sheet Material Having Mechanically Interlocked End Members
Inventor: RENCK LAWRENCE E
IPC: B65H75/18
Filed: 1994-04-14
Abstract: A tubular core assembly for winding or unwinding of sheet material, such as newsprint or Rotogravure Print, is provided wherein the opposed ends of an elongate cylindrical core are provided with inside diameter-reducing annular end members.  The inside diameter-reducing annular end members are mechanically interlocked with a central core body which is preferably formed by multiple wraps of a paperboard material.  Mechanical interlocking is accomplished by a plurality of axial grooves in the bodywall of the central core body member and a plurality of axially extending tongue members on the annular end members which are received in the grooves of the central core body member in interlocking relationship therewith. Because of the mechanical interlocking relationship between the inside diameter-reducing annular end members and the central core body member, the inside diameter-reducing annular end members are secured to the central core body member in positive circumferential and axial locking relationship.

Title: High-Speed Small Digital Multiplier
Inventor: SUZUKI MAKOTO
IPC: G06F7/38
Filed: 1994-05-31
Abstract: A digital multiplier absolutizes a multiplicand value and a multiplier value for decreasing component bits thereof, and multiplies the absolutized multiplicand value by the absolutized multiplier value for producing a product without a sign bit.  The sign bits are produced from the multiplicand value and  the  multiplier  value  independent  from  the multiplication, and the sign bits are added to the data code indicative of the product.   As a result,  the component circuits for producing partial products are decreased, and the multiplication speed is increased.

Patent CA-2145885-A1 (CA)
Title: Method and apparatus for non-snoop window reduction
Inventor: FRY WALTER G
IPC: G06F12/08
Filed: 1993-09-30
Abstract: A method and apparatus which reduces the non-snoop window of a cache controller during certain operations to increase host bus efficiency. The cache controller requires a bus grant signal to perform cycles and cannot snoop cycles after the bus grant signal has been provided until the cycle completes. Cache interface logic monitors the cache controller for cycles that require eith-er the expansion bus or the local I/O bus. When such a cycle is detected, the apparatus begins the cycle and does not assert the bus grant signal to the cache controller. The cache controller thus believes that the cycle has not yet begun and is thus able to per-form other operations, such as snooping other host bus cycles. During this time, the cycle executes. When the read data is re-turned or when the write data reaches its destination, the interface logic provides the bus grant cycle to the cache controller at an appropriate time. By delaying the bus grant signal in this manner, the non-snoop window is reduced.

Patent CA-2165933-A1 (CA)
Inventor: BOOTH ROBERT E JR
IPC: A61B17/02
Filed: 1995-12-21
Abstract: The instrumentation set of this invention assists the surgeon in selecting the proper implant components, in determining the amount of distal bone to resect, and in aligning instrumentation designed to resect the bone. The instrumentation set provides numerous systems for verifying to the surgeon that he has correctly aligned the instruments prior to removing any bone. The set includes a rotational alignment guide, which aids the surgeon in establishing the appropriate rotational alignment for the knee as determined by reference to standard femoral landmarks such as the posterior condyles and epicondyles. The rotational alignment guide includes a slot for guiding a saw blade for removal of the posterior condyles of the femur. The set further includes a tensor designed to tense the knee joint in flexion and extension. The tensor is activated by a torque wrench so that a measured amount of tension force can be applied to the joint. The tensor is configured,to slidably carry sizing rods, which contact the femur and include a plurality of markings, which relate to the size of the femur as well as the spacing between the femur and tibia. This information is used by the surgeon to select the proper size of femoral and tibial articulate surface components. The sizing rods are connected to the tensor when the tibial is in flexion and in extension, which will indicate to the surgeon any variation required in the amount of bone to be resected.
