Abstract: A liveload assembly including a stack guide, compressed belleville washers stacked inside the stack guide and a retainer to hold the compressed washers in the stack guide. A longitudinal slot in the wall of the stack guide permits visual checking of the compression provided by the liveload assembly on the gland follower of the valve or pump. The rotary or reciprocating shaft of a valve or pump is liveloaded by placing the liveload assembly over the bolt securing the gland follower to the stuffing box. A nut is threaded on the bolt until it contacts the washers and the retainer removed.

Abstract: Method and device for controlling the operations of a mammographic X-ray apparatus. In the apparatus the breast (4) to be photographed is pressed between a press plate (2) and a film cassette (5) or an equivalent depicting member. In the method the compression force (F) applied by the holder means to the breast (4) to be photographed, or a quantity that represents this force (F) indirectly, is measured. On the basis of the measurement, the velocity (V) of the compression movement of the press mechanism is regulated. The apparatus comprises a C-arm (1), at one of whose ends the X-ray tube (6) is placed and at the other end the film cassette (5). The C-arm (1) is rotatable around a shaft (8) by means of a motor (9). The device comprises a detector (3) or a series of detectors which measures the compression force and by means of which the operation of the press motor (7) for the breast holders is arranged to be controlled.

Abstract: A method and apparatus for monitoring and testing the operation and configuration of a remote receiver in a utility management system, such as a load management system or a cable television subscriber control system. The receivers are responsive to encoded command signals to perform utility control functions such as remove electrical loads from the electrical distribution system or connect a subscriber to the CATV system. The receiver retrieves status information pertaining to the receiver, and transmits the status information over a data communications link to a hand-held operator display unit. The operator display unit receives the transmitted status information, and displays the received status information to the operator on a display.

Abstract: This invention relates to molding compositions comprising mixtures of wholly aromatic polyesters and fillers. These compositions can be molded, with minimal processing difficulties, into useful articles, such as ovenware, having good mechanical properties and pleasing visual appearances.

Abstract: A wood reinforced corrugated paperboard shipping container with interlocking pallet to direct positioning of the container on the pallet and to interlock the container with the pallet. The pallet includes longitudinal runners and cross members. At least one cross member overhangs the side of a lower runner. The overhang portion of the cross member and the side of the runner together define a recess which receives an attaching strip that is connected to a lowermost portion of the wall of the container. In placing the container on the pallet, a beveled upper surface on the overhang portion of the cross member bears against the bottom surface of the attaching strip. The attaching strip thereby moves downwardly and out to move around the outside end of the overhang portion of the cross member and the back into the recess, thereby matingly interlocking the container to the pallet.

Abstract: An electrical contact element having a contact base, and with a cover-spring provided on and affixed to the contact base. The contact element forms a one-piece punched/bent component of sheet metal with a connector part formed by a crimped member, and with a tubular contact base extending forwardly therefrom. The cover-spring is designed in two pieces, each cover-spring piece having a cover-spring base part. Those base parts are affixed to the contact base opposite each other in relation to the longitudinal midaxis of the contact base.

Abstract: A motor phase insulation device having folding legs that can be easily manufactured with minimum material wasted. The legs are formed from slits in the device material.

Abstract: A method and apparatus for destroying a syringe needle, having a housing, first and second walls in opposed relationship in the housing and defining therebetween a needle burn chamber, the distance between the first and second surfaces being at least the length of the needle, the first surface defining a first opening therethrough, a needle receiving enclosure in the chamber movable between the first and second surfaces and defining a second opening therethrough which is coaxial with the first opening, a first electrical contact on the needle receiving enclosure, a second electrical contact on the second surface and being in registry with the second opening, power source connected to the first and second contacts, a waste collector disposed in the housing beneath and in communication with the burn chamber, the waste collector being removable from the housing and a mechanism that moves the needle receiving enclosure toward the first opening; so that when the needle is inserted through the first and second open

Abstract: A bearing assembly is disclosed in which a bearing having inner and outer races is seated in a manner which accommodates thermal expansion and contraction without allowing radial pressure to constrict the bearing. Two materials of differing coefficients of thermal expansion form the seat for the outer bearing race such that temperature variations cause the race to tilt around the ball of the bearing. The bearing assembly is particularly useful in rotary drive assemblies for antenna pedestals.

Abstract: An opacifying pigment with enhanced light scattering properties for use as a paper coating or filler material is produced by reacting kaolin in the presence of water with sodium hydroxide or potassium hydroxide at a temperature in excess of 60.degree. C. The kaolin is reacted with the hydroxide in a concentration to produce a molality of at least 0.1.

Abstract: A multilayer insulating glass having at least two panes of glass and a resistance heating element on a glass surface. The panes are separated by a spacer comprising two parallel hollow sections and an insulating web of unfoamed and cured polyurethane casting compound filling the interspace between the hollow sections. The web forms a hard and permanent bond with the hollow sections, creating a spacer having relatively high torsional rigidity and electrical insulation and having relatively low thermal conductivity.

Abstract: A pipe coupling includes a cylinder with an axial joint and a sealing device for sealing the fluid pathways between a leak location and the outer surface of the coupling. The sealing device includes arcuate gaskets extending along the inner surface of the cylinder and between axial gaskets which may be adhered to either side of the cylinder's axial joint. A clamping assembly closes the coupling so that an area of overlap is formed between the axial gaskets, thereby sealing the axial joint. The area of overlap is approximately equal to the thickness of the arcuate gaskets so that the sealing device exerts a uniform circumferential pressure upon the pipe without buckling or deforming the seal. The sealing gasket having arcuate gaskets extending between the axial gaskets may be provided separately. The first axial gasket may then be positoned so as to overlap the outer surface of the other axial gasket, and a coupling may be fitted over the gasket apparatus without deforming the seal provided thereby.
