Abstract: Abstract An assembly supporting a plug-on switch unit on a mounting pan pivotally supported within a unit enclosure of an electrical control center and movable between a first position in which the plug-on jaws of the switch unit are connected to respective bus bars within the motor control center and a second position in which the plug-on jaws are spaced away from the bus bars.  The assembly includes a handle operator movable between a first position indicating that the switch unit is in an "OFF" condition and a second position indicating that the switch unit is in an "ON" condition.  Interlock features are provided to prevent movement of the mounting pan from its first position to its second position unless the handle operator is in its first position and also to prevent removal of the unit enclosure from the motor control center unless the mounting pan is in its second position.

Title: Mechanical shift, pneumatic assist pilot valve for diaphragm pump
Inventor: GARDNER RICHARD K
IPC: F01L25/06
Filed: 1988-08-16
Granted: 1991-02-26
Abstract: ABSTRACT OF THE DISCLOSURE     Briefly, the present invention comprises a combined mechanical shifting mechanism and pneumatic pilot valve construction to control the cycling of a double diaphragm pump.          The mechanical cycling or shifting mechanism is positioned between pressure chambers of the diaphragm pump in the pump housing and extends axially into one or the other pressure chamber. The shifting mechanism moves axially in response to engagement by one of the pump diaphragms. Upon engagement by a diaphragm, the mechanical shift opens fluid pressure passageways to a pneumatic pilot valve which controls fluid flow to the respective pressure chambers associated with the diaphragm pump.          A positive pilot signal is thus supplied through the entire stroke or cycle of the diaphragm pump. The mechanical shifting mechanism is not connected directly to a diaphragm or to the connecting rod which connects the diaphragms.

Abstract: A method of preparing a labelled specific binding partner, such as a biological probe in the form of an antibody or oligonucleotide probe, using a protected label the corresponding unprotected label being susceptible to inactivation, such as by hydrolysis to yield a non-chemiluminescent form of the label.          The specific binding partner is linked to the label, and an adduct of the label is prepared using a protective adduct former which produces a protected label which is less susceptible to inactivation.  Particularly preferred labels are the acridiniums and acridans, most preferably the former having the general structure:       wherein the phenyl rings are optionally additionally substituted, R1 is preferably an alkyl, and R5 is an optionally substituted hydrocarbon, most preferably a phenyl moiety which is either linked to the specific binding partner, or capable of being linked thereto.  Formation of the protected label is preferably an equilibrium reaction which is readily reversible, such as by dilution or oxidation of the protective adduct former.  Labels useful in such a method are also disclosed.

Abstract: There are described novel dispersible cimetidine tablets containing 30 to 90 % by weight of one of the polymorphous modifications of cimetidine A, B or C, 5 to 55 % by weight of one or more disintegrationg agents, 0.05 to 5.0 % by weight of a surfactant, such as sodium lauryl sulphate together with other common adjuvants.   The process for the manufacture of dispersible cimetidine tablets is effected on the basis of known methods by granulating the ingredients and by compressing the granu-late to tablets.   Dispersible tablets disintegrate when brought in contact with water at room tempera-ture within less than 1 minute to yield a fine dispersion, which facilitates the oral ap-plication. Therefore such tablets are particularly suitable for certain groups of patients, especiallly for the aged and children. Dispersible tablets containing cimetidine excell by their improved rate of dissolution and good bioavailability.

Abstract: The wide, thin, revolvable, flexible, metallic casting belts are made to incorporate differential patterns of residual internal longitudinal tensile and compressive stresses.  The two marginal areas are residually longitudinally stretched more than the main middle area straddled by these margins.  This main middle area is used as a moving mold and is expected to contact molten metal.         Thus, the treated belts have two marginal areas in a state of mild longitudinal compression straddling the main middle area in a state of mild residual longitudinal tension.  During casting, when hot metal comes into contact with the main middle area of such treated belt, the main middle area expands.  Because of the built-in differential compensating stresses, the stresses throughout such belt during casting advantageously become balanced or equalized across the whole belt width.  This equalized stress condition during casting assures that the critical moving belt mold area will be flatter than experienced with belts not having differential stress treatment.  Thus, cast metal product typically will be improved in flatness, surface finish, section uniformity, soundness and metallurgy.  Two methods are described for longitudinally stretching marginal areas relative to the middle area:  (A) Use a work roller effectively of larger diameter toward its end than its middle for stretching both margins relative to the main middle area; (B) Use conventional cylindrical work rollers and heat (for expanding and slacking) the middle area during roller-stretching while leaving cold margins for residually stretching both margins relative to the main middle area.
