An integrated infusion management system provides for stable support of components attached to the system, even when the system is mobile. The system is optionally a mobility assist or walker for a patient who is attached to any number of medical components. A central trunk connects to a two-sided base that does not interfere with patient motion. The trunk may be angled with respect to vertical and oriented to support medical components in a configuration that is tip-resistant. The system is optionally deployable to facilitate conversion between a compact storage configuration and a stable deployed configuration. In an embodiment, additional deployable features include holding arms for holding various medical components, wheels, mobility arms and handles. Also provided is a novel wheel system with deployable wheels and methods associated with providing compact storage of any one or more of the systems presented herein.

A method for processing an outer circle of a cylindrical part based on upper plate eccentric pressurizing. A processing device for achieving the processing method comprises an upper grinding plate, a holder and a lower grinding plate. The upper grinding plate is located above the lower grinding plate, the holder is located between the upper grinding plate and the lower grinding plate, a rotating shaft of the holder and a rotating shaft of the lower grinding plate are coaxial, and a definite offset distance exists between a rotating shaft of the upper grinding plate and the rotating shaft of the holder. In the process of processing, a loading device eccentrically acts on the cylindrical part through the upper grinding plate, and the outer circle of the cylindrical part is processed through the cooperation of a plane of the upper grinding plate, a plane of the lower grinding plate and matched abrasive materials. The method for processing the outer circle of the cylindrical part is high in precision and good in consistency.

The present invention provides a split outer race for use in a rolling bearing. The split outer race is formed by bending a strip-shaped metallic plate into a substantially semicircle shape. At least one end of the split outer race in a circumferential direction has a concave-and-convex shape including a first slope portion which is inclined to an axial direction and a second slope portion inclined in a direction opposite to a direction in which the first slope portion is inclined. An edge portion formed on an inner surface of the one end in the circumferential direction has a round shape.

A linear motion guide unit is disclosed in which a joint tube connects between a turnaround and a return passage of a sleeve made of sintered resinous material to ensure smooth turnabout of rolling elements and further in which lubricant can be supplied to the rolling elements for a prolonged period, thereby refining the durability. A slider is comprised of a sleeve for a return passage held with clearance fit in a through-hole of a carriage in a way lining major area of the through-hole with only forward and aft ends of the through-hole being left naked, a spacer with a lug having a radially inside curved half for a turnaround and an inside part for a joint tube to make up for any one end of the return passage joining with the radially inside curved half, and an end cap having a radially outside half for the turnaround and an outside part for the joint tube to make up for any one end of the return passage joining with the radially outside curved half.

This invention relates to a type of steel used for saw blade for stone slotting. Account for weight the chemical composition is: C 0.45-0.60,Si 0.10- 0.60,Mn 1.30-1.80,P<=0.02,S<=0.01,V 0.05-0.20,Cr 0.15-0.30, N 0.005-0.020,Ca 0-0.0050,Al 0.005-0.040, and the rest is Fe and inevitable impurity. The process includes steps as follows: smelting, casting,; continuous casting billet use heat sending and heat packing , ensure the temperature keep above 300DEG C before it be send into plate body for heating; keep temperature for plate body heating above 1150DEG C,temperature for hot rolling above 900DEG C; cooling after rolling, then coiling, keep the coiling temperature above 700DEG C. This invention has higher hardenability then midst-carbon and low-alloy steel, especially refer to make large saw blade which diameter is above 1000mm.

A putter head includes substantially parallel plural grooves formed on a face thereof, wherein a ratio W / S of a groove width W (mm) and a space width S (mm) between the grooves is from 0.5 to 2.0.

The invention relates to an indoor grinding and forming instrument of a bituminous mixture test specimen and a forming control method thereof. The forming instrument comprises a rack, a grinding wheel, a mould and a mould drive device, and also comprises a grinding wheel drive device; the device mainly comprises a first reducing gear, a grinding wheel support, a hydraulic ram, a first guide rail and a driving chain; the mould drive device mainly comprises a mould driving support, a second guide rail, a second reducing gear, a speed reducing elevator mechanism, an elevating platform and a horizontal screw; the grinding wheel is arranged on the grinding wheel support, the grinding wheel support is connected with the first reducing gear, the mould drive support is connected with the second reducing gear through the horizontal screw, and the speed reducing elevator mechanism is fixed on the mould driving support and connected with the elevating platform. The method comprises the steps of:setting parameters, judging whether a starting position is reached or not, applying a grinding force, comparing a pressure value with a set value, grinding with the grinding wheel, judging whether one round of grinding is ended or not, and the like. The grinding and forming instrument has the advantages of high simulation degree, high automation degree and wide application range.

A portable tire and wheel lifting apparatus includes a base, a pair of lifting arms pivotally coupled in a scissor configuration, pneumatic cylinders, an air input device, and an air outlet valve. In use, a tire and wheel are smoothly rolled from the ground to the lifting arms, which are in a retracted configuration. The air input device adds air to the pneumatic cylinders, causing the lifting arms to move from the retracted to an extended configuration, thus raising the tire and wheel. The tire and wheel are turned to line up the rim with the vehicle's hub and fastened to the vehicle. The air outlet valve selectively releases air from the pneumatic cylinders, allowing the lifting arms to move from the extended to the retracted configuration. The tire and wheel lifting apparatus is small enough to fit inside the cavern defined by a spare tire and wheel for storage.
