摘要:
A power line puller control package facilitates the installation of conductor or high tension power lines by directing the conductor or high tension line removal from at least one supply reel at a substantially stable rate, while adjusting the speed of the drum to the amount of the rope or cable on the at least one holding drum, to facilitate manufacturing, installation or use of the high tension power line at a substantially constant speed and tension.

摘要:
The present invention is an apparatus for multiple-pitch carrier tape feeding, including a carrier tape reel support, a slidable tape window and cover tape peel edge for exposing a component at a pick location adjacent a peel edge, and a carrier tape drive mechanism for advancing the carrier tape through the tape guide. The feeder also includes a pitch selection cam having a plurality of positions, each corresponding to one of a plurality of carrier tape pitch sizes, wherein movement of said selection cam is directly translated into movement of the tape guide. A sensor is employed for detecting the position of the selection cam, and a control unit, responsive to the sensor, controls the carrier tape drive, thereby advancing the carrier tape a predetermined distance according to the selected pitch size.
摘要:
Porous bodies are produced which are suitable for use as supports for catalysts, including living cells, such as bacteria and which are upset resistant to acids and bases. The bodies have a significantly large average pore diameter of about 0.5 to 100 microns, (i.e. 5,000 to 1,000,000 .ANG.) and a total pore volume of about 0.1 to 1.5 cc/g with the large pores contributing a pore volume of from about 0.1 to 1.0 cc/g. The bodies are made by preparing a mixture of ultimate particles containing a zeolite and one or more optional ingredients such as inorganic binders, extrusion or forming aids, burnout agents, or a forming liquid, such as water. In a preferred embodiment, the ultimate particles are formed by spray drying.

摘要:
Apparatus for deriving signals indicating a condition of tissue within an area by launching spaced supersonic pulses into a body under examination and detecting the power of supersonic waves scattered from locations along a plurality of known paths. Gain control elements are provided for compensating for changes in amplitude of the scattered supersonic waves resulting from their passage through blood or tissue, the increased attenuation with frequency of the spectrum of the launched pulses and the focussing of the launched pulses. Compensation for ring-down and the attenuation of the chest wall is also provided.
摘要:
An incubator assembly useful in a clinical analyzer having at least two incubators, each having a rotationally driven rotor assembly having a plurality of slide element holding stations, which incubators are stacked one above the other to define a substantially vertical arrangement. In a preferred embodiment, in which the incubators are of varying size, the smaller rotor assembly is horizontally offset so that the outside diameter of each rotor assembly is coincident in one location, preferably an input station, so that slide elements can be loaded into and removed more conveniently from either rotor assembly.
摘要:
An incubator and its cover are provided for an analyzer, and especially a mechanism for raising and lowering the cover. Such a mechanism includes a connector between the cover and incubator that allows the cover to be raised to a superimposed position, but not rotated. A pivot pin is mounted directly between the connector and the cover so that the cover can be pivoted relative to the connector to complete exposure of the incubator for access. A latch is provided on the connector for automatically latching the cover in the raised position as soon as the cover is pivoted in the plane at least part way from the superimposed position.

The bodies are made by preparing a mixture of ultimate particles of bound clay, one or more optional ingredients such as inorganic binders, extrusion or forming aids, burnout agents, or a forming liquid, such as water. In a preferred embodiment, the ultimate particles are formed by spray drying.

摘要:
When a zeolite additive composition of a medium-pore zeolite with a Constraint Index from about 1 to about 12 and a silica to alumina mole ratio greater than about 12 is added to a conventional cracking catalyst dispersed in an inorganic matrix, the octane will be improved, but there will be a yield loss in the amount of gasoline produced. An improvement in that catalyst system is obtained by partially exchanging the medium-pore zeolite additive with cations from one or more elements of Group IA, Group IIA or Group IIIA excluding rare earths of the Periodic Table. The octane number of the gasoline-range product of an FCC process is still improved while the amount of the gasoline yield loss typically observed for such octane-enhancing additives is reduced.
摘要:
An analyzer incubator is provided in which evaporation caps have feet extending through a support on which the caps and covered test elements rest. A preferably fixed mechanism is provided underneath the support to raise and cover both sides of each cap simultaneously to avoid any significant sideways thrust on the cap or on a test element underneath. The cap preferably has downwardly depending feet positioned to cooperate with this mechanism, through the support.
