A clamp secures disks to a hub through means of a push-on retaining ring which is engaged with a grip ring received in an annular groove extending around the hub. The grip ring is split and expansible to enable it to be engaged with, or removed from, the groove. Spaced detent grooves are formed in the external surface of the grip ring to provide different positions at which the retaining ring may be engaged with the grip ring to alter the degree of compression imparted to the disks by the retaining ring. The retaining ring may be pushed fully past the grip ring to release the clamp. An installation and release fixture is provided to selectively move the retaining ring over the grip ring.
摘要:
Membrane separation of monosaccharides from an aqueous solution containing higher saccharides and saccharifying enzyme is considerably improved when the separation is performed under conditions where the polarization modulus for the enzyme is between 10 and 1,000, especially when the latter is between 50 and 500. A process utilizing this constraint affords a considerable savings in enzyme residence time and enzyme usage, and permits glucose of at least 94% purity to be prepared using membranes with a molecular weight cutoff as high as 70,000 with partial saccharification of thinned starch to give glucose levels in the range of 65-90%.

Polynuclear aromatic compounds are irreversibly adsorbed by coconut charcoal and are separated from desired constituents by treatment in a coconut charcoal column. This invention is particularly valuable in providing a method suitable for large scale use for removing dioxins and other undesirable polynuclear aromatic hydrocarbons which are found as impurities in small but highly toxic amounts in industrial compounds and herbicides such as 2,4,5-T, 2,4-D and derivatives thereof.

A cap, jacket, shirt, or sweatshirt displaying the logos of two rival adjacent a field, court, mat or rink depicting the sport in which the teams vie. These logos may be readily ripped-off, being attached by hook-and-loop fabric, or the like, to enable the following week's rivalry to be displayed on the same item of apparel. The wearer's preference is displayed on that item of apparel by means of a team name/logo/exhortational message displayed elsewhere on the item than in the display region and by a red ‘DIS’ cord stretched across the team the wearer wishes to lose in a manner reminiscent of the international NOT! display.
摘要:
A cooler having a foot operated lid. The cooler includes a body, a lid, and a mechanism for opening the lid. The mechanism includes a pedal, the application of force to which causes the lid to move relative to the body. A cooler may also have a plurality of sides and a dry erase board mounted onto at least one of the sides. A cooler may also have a compartment inside at least one of the sides that is accessible by opening a door. A cooler may also include a bin or panel on at least one of the sides that is rotatably attached to at least one of the sides. The opening of the bin or panel allows access to the interior of the cooler without opening the lid.

A system-on-a-chip and method for securely transferring data can include a trusted master; a first trusted slave; an untrusted component; and a common bus coupling the trusted master, the first trusted slave, and the untrusted component, In response to an initiation by a host, the trusted master provides a first access request to request a first data transfer with the first trusted slave, and wherein the trusted master does not perform the first data transfer until authentication of the first trusted slave.
摘要:
An oven assembly for a crystal resonator and oscillator utilizes a thermally symmetrical design to provide a high thermal gain. The oven assembly includes an encasement that forms a hermetically sealed oven chamber that is substantially cylindrical. Concentric with the oven chamber is an annular oven mass that functions as a heat reservoir for the crystal resonator that is contained within the oven mass. The cylindrical oven chamber and the concentric annular oven mass provide two levels of circular symmetry that help achieve a thermally isotropic oscillator environment. Wide-area uniform heat transfer promotes high thermal gain and minimizes thermal gradients. Another factor is the geometry and circuitry for temperature monitoring. Temperature sensors are equidistantly spaced from each other and are equidistant from the center of the oven chamber. Signals from the various thermistors are averaged to provide a more accurate temperature determination for regulating the heaters.

An improved atomic beam tube assembly is disclosed in which the operating parameters for the atomic beam tube are contained in a programmable read-only membery located in the end of the cable used for connecting the atomic beam tube assembly to the support electronics. This arrangement eliminates the selected resistors normally used with such beam tube assemblies.
