Orthopedic support devices are provided that include a first layer of elastomeric material is attached directly atop or around a layer of a spacer material, wherein the first layer provides support and / or compression, and the second layer provides breathability and wicking and wherein characteristics of the first layer can be varied in order to vary the location, amount and / or level of compression provided by the support device.

A vacuum locking hub system is provided for a four-wheel drive vehicle that includes a cartridge-type assembly that allows the vacuum locking hub system to be inserted into the wheel as a cartridge unit for ease of assembly. The vacuum locking hub system has a compact construction allowing it to be substantially received within the wheel hub, thus reducing system mass and unit length.

A method of mass spectrometry having steps of, in a first cycle: storing sample ions in a first ion storage device, the first ion storage device having an exit aperture and a spatially separate ion transport aperture; ejecting the stored ions out of the exit aperture; transporting the ejected ions into an ion selection device which is spatially separated from the said first ion storage device; carrying out ion selection within the spatially separated ion selection device; returning at least some of the ions ejected from the first ion storage device, or their derivatives, back from the spatially separate ion selection device to the first ion storage device, following the step of ion selection; receiving the said returned ions through the ion transport aperture of the first ion storage device; and storing the received ions in the first ion storage device.

A method of forming an article from an α−β titanium including, in weight percentages, from about 2.9 to about 5.0 aluminum, from about 2.0 to about 3.0 vanadium, from about 0.4 to about 2.0 iron, from about 0.2 to about 0.3 oxygen, from about 0.005 to about 0.3 carbon, from about 0.001 to about 0.02 nitrogen, and less than about 0.5 of other elements. The method comprises cold working the α−β titanium alloy.

A capper head for general purpose usable even when the specifications of a cap including thread pitches are changed without using a fixed gear and a lifting cam determining a lifting stroke and the timing thereof. The rotational output of a servo motor (2) is transmitted to a screw mechanism (4) through a sliding engagement section (3), and a screw shaft (17) is lowered while rotating for capping. The lowering stroke of the screw shaft (17) is allowed by the sliding engagement section (3). In capping, even if the strokes of a rotating chuck (7) and an output shaft (31) are different from the lowering stroke by the screw mechanism (4), a stroke difference absorption section (5) absorbs the stroke difference therebetween since a spring (23) in combination with a spline transmitting the rotation is deflected in the axial direction.

Formulations and methods to promote biological processes to form or regenerate new hard tissues such as bones, cartilage, and / or dental tissues are disclosed. The formulation enhances biological activities of a hard tissue growth and differentiation factor characterized by specific and selective upregulation and / or extension of the retention time of the intracellular enzymes and signaling molecules that play important roles to proliferate, differentiate, maturate, and / or mineralize the hard tissue forming cells.

A high-pressure pump has at least one pump element, with a pump piston which is guided displaceably in a cylinder bore of a housing part of the high-pressure pump and is driven in a reciprocating motion and defines a pump work chamber in the cylinder bore, into which chamber fuel is aspirated via an inlet valve in the intake stroke of the pump piston. The inlet valve has a pistonlike valve member, which with a sealing face cooperates with a valve seat for controlling the communication of the pump work chamber with the fuel inlet. The valve member is disposed with a head, on which the sealing face is embodied, in the pump work chamber and protrudes out of the pump work chamber with a shaft adjoining the head. The valve seat is formed in the housing part at a transition from the cylinder bore to a bore of smaller diameter adjoining the cylinder bore. With its shaft, the valve member protrudes through the bore into a region of the housing part remote from the pump work chamber, in which region a closing spring is disposed that engages the shaft of the valve member.

Methods of retarding the setting of a cement composition comprise including one or more secondary amines substituted with a carboxyl group or salts thereof (e.g., 3-hydroxy N,N′-iminodisuccinic acid) in the cement composition. The inclusion of such materials in cement compositions may be highly beneficial. In wellbores having BHCT's of less than or equal to about 250° F., the use of the secondary amine as the set retarder ensures that the thickening time of the cement composition is sufficient to allow the cement composition to be pumped to its desired downhole location. Further, the secondary amine may be used in combination with conventional set retarders to enhance the ability of those retarders to increase the thickening time of the cement composition at higher BHCT's, e.g., from about 250° F. to about 525° F.
