Abstract: An insulating unit is disclosed having a pair of glass sheets about an edge assembly to provide a compartment between the sheets. The edge assembly has a U-shaped spacer made of metal, metal coated plastic, gas and moisture impervious polymer, or gas and moisture impervious film coated polymer. The outer legs of the spacer and the glass provide a long diffusion path to limit the diffusion of argon gas out of the compartment. The edge assembly has materials selected and sized to provide edge assembly having an RES-value of at least 75. Also disclosed is a spacer for use in insulating units including a plastic core having a gas impervious film e.g. a metal film or a halogenated polymer film. Also taught herein are techniques for making the unit and spacer. The unit has a long diffusion path to increase the time period in which insulating glass e.g. Argon gas may be retained in the compartment. The increased RES-value provides a unit that has a low thermal conducting edge. In this manner heat loss through the marginal edge of the unit is reduced.

Title: Down pressure spring adjustment
Inventor: LOWE TERRY LEE
IPC: A01B71/02
Filed: 1995-10-27
Granted: 1997-08-12
Abstract: A series of notches are provided in the upright plates on one end of a parallel bar linkage connecting a cultivator rig or planter assembly to a tool bar.  Coil springs are tensioned between the opposite end of the linkage and a rod and trunnion assembly that fits into the series of notches.  The coil springs maintain the rod and trunnion in a selected set of notches.  A handle on the rod allows the operator to walk the rod and trunnion assembly up and down the series of notches to select a different set of notches and thereby incrementally adjust the down pressure to a known value or setting.  When the tool bar is raised to a transport position and the linkage pivots downwardly to a lowermost position, the spring is stretched only slightly so that down pressure adjustments can be made easily using only the handle on the rod.

Title: Instrumentation for use in orthopaedic surgery
Inventor: STALCUP GREGORY C
IPC: A61B17/15
Filed: 1995-12-21
Granted: 2008-04-29
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.
