Abstract: A first kit includes a manually operable hydraulic pump, a hose and a fitting for transferring the pressure in the pump to the hose. A second tool kit for bearings of relatively small size includes a fitting for coupling to the hose in the first kit and a C-shaped clamp having a pair of legs movable toward each other in accordance with increases in pump pressure. A third kit includes a receiver die and a driver die movable with the clamp legs to remove a bearing from a housing, an anvil die and a driver die for installing a bearing in a housing and a die set for swaging a prepared lip in a bearing race into a prepared chamfer in a housing. A fourth tool kit for bearings of relatively large size includes a fitting for coupling to the hose in the first kit and an in-line press having a pair of legs movable toward each other in accordance with increases in pump pressure.

Abstract: A one way clutch is rotatable with a member (e.g. helical spring) and a sleeve while the spring is being constrained by the manual winding of a cable on the sleeve. The sleeve is constructed to wind the cable uniformly on the sleeve. During the constraint imposition, the clutch drives a shaft and a disc. One disc surface abuts bearing liners affixed to a casing. The other disc surface is separated from the spring. Calibrated numbers are printed on the casing periphery. A dial externally supported by, the casing is rotatable relative to the casing to any of the calibrated numbers to adjust the friction force between the liners and the disc when the disc is rotated. The casing is vented at its opposite ends. When the spring is being constrained or the constraint is being released, air flows through the vents and through the space between the successive turns in the spring and past the disc to cool the disc.

Abstract: An endoscope for insertion into a patient's inner body cavity has a shell with lumens for (1) illuminating a lens and (2) passing light from an imaging (or objective) lens, each lens being disposed on the distal face of the shell. The shell also has a lumen, preferably off-round, for receiving a resilient disposable core. The resilient core has passageways for introducing a pressurized fluid (e.g. air or water) to selective ones of the lenses to clean the lenses. The core may also have another passageway for removing material from the patient's inner body cavity for analysis. This passageway may communicate with two (2) conduits for removing specimens from the body cavity (1) as by a vacuum or (2) as by an instrument. The second conduit may be closed except when the instrument is to be inserted into a patient's inner body cavity. The core may be drawn through the shell lumen to position the core in the lumen.

Abstract: One end of a hollow cylindrical tube is attached to a tubing positionable in a patient's body. A radial flange on the tube supports a collar in abutting relationship to one flange surface. Lugs extend integrally from the collar through the flange for disposition against the opposite flange surface. The collar extends radially past the tube's inner periphery and has slots at its inner periphery. Stops integral with the inner periphery of the collar are annularly displaced relative to the slots. Ramps on the collar lead to the stops. A piston in the tube along part of its length has, at the end within the tube, a sleeve in sealed relationship with the tube is inner periphery. Splines have grooves at spaced positions along their axial lengths at the radially outer ends of the splines. A handle at the piston axial end has an aperture to receive a user's finger for manual adjustment of the piston axially relative to the tube.

Abstract: An inverter receives an energizing voltage with a particular magnitude (e.g. 1.5 V) at a first terminal and produces the voltage at a second terminal. The received and produced voltages are differentially introduced to a stage which produces a single-ended bias voltage (e.g. 3 V) related to the second terminal voltage. The bias voltage is servoed to regulate the second terminal voltage (e.g. 1.5 V) and the bias voltage (e.g. 3 V) regardless of energizing voltage variations. In response to the bias voltage and a variable input voltage, a pass transistor in a buffer produces a first control voltage different from the bias voltage by the pass transistor threshold voltage for input voltages greater than a value equal to the bias voltage less the pass transistor threshold, and corresponding to the input voltage for input voltages less than the bias voltage less the pass transistor threshold.

Abstract: A manifold is disposed within a pair of abutting pre-load mold plates in a pre-load relationship. Fluid flowing through the manifold is heated by a first heater. The fluid is then divided into a plurality of passages in the manifold. Pairs of passages have a back-to-back in-line relationship. A cylinder between each pair of the in-line passages holds a pair of pistons in the in-line relationship. Each piston in the pair has piston units in an interdigitated relationship with piston units on the other piston in the pair. Each pair of pistons is movable by pressurized fluid (e.g. air) between first and second positions. In the first position, each piston provides for the fluid (e.g. resin melt) flow through one of the passages to a pair of runners in the manifold. In the second position, each piston prevents the resin melt flow through the passages. A first heater heats the resin melt flowing through the passages. A second heater heats the resin melt flowing through the runners.

Abstract: A bridging member extending across a cavity in a semiconductor substrate (e.g. single crystal silicon) has successive layers--a masking layer, an electrically conductive layer (e.g. polysilicon) and an insulating layer (e.g. SiO.sub.2). A first electrical contact (e.g. gold coated with ruthenium) extends on the insulating layer in a direction perpendicular to the extension of the bridging member across the cavity. A pair of bumps (e.g. gold) are on the insulating layer each between the contact and one of the cavity ends. Initially the bridging member and then the contact and the bumps are formed on the substrate and then the cavity is etched in the substrate through holes in the bridging member. A pair of second electrical contacts (e.g. gold coated with ruthenium) are on the surface of an insulating substrate (e.g. pyrex glass) adjacent the semiconductor substrate. The two substrates are bonded after the contacts are cleaned.

Abstract: A master tape moves between first supply and take-up reels over a pinch roller. A slave tape moves between second supply and take-up reels over a capstan. First and second guides are respectively constructed and positioned to regulate the movement of the master and slave tapes to aligned positions on the pinch roller and the capstan. A heater between the pinch roller and the second guide heats essentially only a thermomagnetic layer on the slave tape to at least the Curie temperature. The heater is adjustably positioned to facilitate the movement of the slave tape to the aligned position on the capstan. Brake shoes respectively between the first guide and the first supply reel, and between the second guide and the second supply reel, control master and slave tape tensions and damp any variations in tensions. The pinch roller is movable to a first position, locked in position relative to the capstan, to abut the capstan and facilitate the transfer of magnetic information from the master tape to the slave tape.

Abstract: A peripheral portion in a hub is hollow, flat and defined by a pair of spaced and parallel surfaces. An annular periphery in this portion holds a tape in a wound configuration. An additional portion integral with the inner periphery of the peripheral portion has undulations each disposed radially. The undulations extend progressively in an annular direction. Preferably the undulations are in the form of corrugations each having oppositely disposed segments. Preferably each corrugation segment has the same angle as the other segment in such corrugation, this angle preferably being approximately 47.degree.. Preferably the additional portion has first and second surfaces shaped to define the corrugations. Preferably the first surface of the additional portion is alternately substantially flush with one flat surface of the peripheral portion and then is spaced outwardly in a first axial direction from the other flat surface of the peripheral portion.

Abstract: A nozzle body has a runner, a passage and an orifice, all communicating with one another to provide for fluid flow into and through the body. The fluid is heated during its flow through the nozzle body by an electrical heater on such body and by a heat conductive plug (e.g. copper) extending through the nozzle. A cap made from a heat insulating material (e.g. titanium) and disposed in a tight fit on the nozzle body has a gate well for receiving the fluid in the orifice and for injecting such fluid into a mold. The cap is constructed so that fluid cannot leak into the area around the cap when heated fluid flows through the gate well. The cap is also constructed so that the article formed in the mold from the fluid injected into the article will shear to provide a smooth peripheral surface when the article is ejected from the mold after solidifying.

Abstract: A thin transparent epitaxial layer of a magnetizable material (e.g. gallium ferrite) is deposited on a substrate of a dielectric transparent material (e.g. gadolinium gallium garnet). A mask made from an oxidizable material (e.g. silicon) deposited on the epitaxial layer covers pixels defining rows and columns and exposes the other areas on the epitaxial layer. The epitaxial layer is then annealed at a suitable temperature (e.g. 500.degree. C.) for a suitable time (e.g. 10 minutes) to oxidize the silicon and reduce the Fe atoms in the pixel areas beneath the mask to Fe.sup.++ ions. This causes the pixel areas beneath the mask to be more easily magnetizable than the other areas in the epitaxial layer. The mask is then removed and a first insulating layer is deposited on the epitaxial layer. A first plurality of windings is then deposited on the first insulated layer in insulating relationship to one another.

Abstract: Athletic and other footwear has an upper and also an insole, a midsole and an outsole in successive layers. The midsole may be made from a flexible material (e.g. polyurethane or EUA) and may be shaped to conform to the shapes of the insole and the outsole. A cavity in the midsole at a forefoot position extends from the top surface to a position near the bottom surface of the midsole. The cavity may extend downwardly and rearwardly at an angle of approximately 10.degree.-45.degree., preferably approximately 15.degree. to the horizontal. The cavity may be undercut to provide a recess at the bottom of the cavity. A spring disposed in the cavity may have a slightly concave configuration in the cavity. The spring may have a flat configuration at the opposite ends of the spring in the longitudinal direction. The spring may be made from a fabric material woven with a warp and a fill and impregnated with a resin material.
