摘要:
Composite mixture materials made of recycled plastic, glass and rubber, and optionally, sand, gravel, coal combustion by-product and metal, and containing no petroleum distillates (unless a fire retardant or recycled asphalt pavement is used) are disclosed. Methods of using the composite mixture materials include making expansion joints in pavement, filling manhole cover recesses, filling potholes in pavement, making new pavements, and making panels, walls, blocks, impact protection walls, and other such structures. Methods of making the composite mixture materials include heating the components of the material in an inert gas environmentally friendly manner. Compressive pressure is applied to composite mixture materials used in making expansion joints, manhole cover recess fillers, and in filling potholes to build in an elastic strain to overcome both a composite material shrinkage on cooling solidification of the material and the thermal contraction of pavements, and in making the composite material for any other of the uses disclosed.

An apparatus for improving sheet feeding in a direction of movement to a process station, including: a contact surface having ribs spaced along contact surface in the direction of movement, apertures being defined in the space between each rib; a blower; and an air plenum for supplying a vacuum generated by the blower to the contact surface so that when an leading edge of the sheet passes by the contact surface the vacuum pulls the leading edge of the sheet towards contact surface.

A collapsible generally cylindrical storage vessel having a flattened ramp end portion which accommodates driving upon by a vehicle or the like to pressurize the vessel and dispense fluid, as required. The ramp end is internally reinforced with a bridging insert which inhibits blowout upon pressurization.

A tibial sizing apparatus includes a tibial sizing plate. The tibial sizing plate includes a substantially planar surface and defines a peripherally positioned pin slot extending obliquely relative to the substantially planar surface. An alternative tibial sizing apparatus includes a tibial sizing plate and an angulated handle coupled to the tibial sizing plate. An alternative tibial sizing apparatus includes a tibial sizing plate and a catch member coupled to a peripheral portion of the tibial sizing plate. The catch member is movable between a first position in which the catch member extends generally inferiorly from the tibial sizing plate and a second position in which the catch member retracts generally superiorly into the tibial sizing plate. A method for fixing a tibial sizing plate to a proximal tibia includes anteriorly pinning the tibial sizing plate to the proximal tibia.

An orthopaedic instrument and a method for its use in sizing a glenoid implant anchor site and for pressurizing bone cement in the anchor site. The instrument has a shaft with a handle on one end thereof and a pressure plate on the other end thereof. An implant site probe, corresponding in shape to the glenoid implant anchor, extends outwardly from a bone facing surface of the pressure plate. A seal against the bone facing surface surrounds the implant site probe. Forcing the implant site probe into the implant site filled with bone cement forces bone cement into the cancellous bone surrounding the implant site.

A method for Inserting and fixing a mounting insert into a lightweight sandwich panel. The panel comprises a core layer and two cover layers that are applied to opposing main surfaces of the panel. A recess extends into the depth of the core layer of the panel. The mounting insert is inserted into the recess and is adhesively bonded therein. The bottom of the recess extends to a depth of the core layer material that extends further than the longitudinal extension of the recessing section to be inserted. When adhesively bonding the mounting insert, an air gap remains between an end face of the recessing section and the bottom of the recess. No adhesive is placed into the air gap. The air gap ensures a decoupling so that any applied tensile forces are no longer transferred to the cover layer opposite and the undesired formation of dents is avoided.

Some embodiments of the invention relate to a method of packaging multiple dice into a semiconducting device. The method includes placing a first capsule that includes a first die onto a front side of a tape substrate, placing a second capsule that includes a second die onto the front side of the tape substrate, filling a recess in a surface of the first capsule with an adhesive and folding the tape substrate to attach the first capsule to the second capsule using the adhesive. The method may further include placing a third capsule that includes a third die onto the front side of the tape substrate such that folding the tape substrate includes positioning the third capsule against a back side of the tape substrate opposite to the second capsule.
