A particulate co-processed unattrited microcrystalline cellulose:hydrocolloid composition wherein the respective components are present in a weight ratio of from about 99:1 to 70:30. The composition is useful as a spheronizing agent for producing spheroids of uniform size and sphericity and having high drug loadings. The composition is produced by drying a slurry of the microcrystalline cellulose in an aqueous solution of the hydrocolloid. The preferred hydrocolloid is methylcellulose.

A solid dosage form, such as a pharmaceutical tablet, containing a rapidly hydratable konjac glucomannan sustained release excipient such as clarified konjac, cryogenically ground konjac and plasticized konjac. The method of making the tablets by compressing excipient and pharmaceutically active ingredient as dry powders.

A water dispersible polymeric film-forming particulate composition for use in coating pharmaceuticals and foods or the like, produced by freeze-drying an aqueous solution of water-soluble cellulose acetate as the film-forming polymer, a plasticizer, and optionally a pigment, is described. The product mixes readily with water to form an aqueous dispersion which is applied in the conventional manner to solid pharmaceutical forms.

Film-forming composition: method of producing same and use for coating

A water-dispersible, particulate film-forming composition is produced by blending a mixture of particles of water-soluble cellulose acetate; pigment particles, a plasticizer for the water-soluble cellulose acetate, and a surfactant. The composition is useful as a film-forming material for coating solid pharmaceutical forms.

A coated aspirin tablet, which is capable of being disintegrated quickly in gastric fluid, containing a thin film of plasticized ethylcellulose. The ethylcellulose thin film coating represents less than about 2 wt % of the coated tablet weight and is the dried residue of an aqueous ethylcellulose dispersion that is spray-coated onto the tablet.

The preferred and illustrated embodiment of the present disclosure is directed to a stud bolt incorporating a thread preventing leakage along the thread of the tapped blind hole receiving the stud bolt wherein the thread is modified with a shallow root and a crown of increased width for at least one full turn.

Leakproof stud bolt incorporating modified thread

This disclosure is directed to a full opening check valve for use in a pipeline. The apparatus incorporates a funnel shaped body which is welded to a pipe in the pipeline. The body encloses a chamber and an axial half circle guide extends thereacross and along part of the chamber to serve as a guide for pipeline pigs passing through this device. The funnel shaped body is welded to an end plate. The end plate has a slightly recessed circular shoulder on the inside. The circular shoulder sealingly receives a valve element. The valve element is constructed of a flat plate member and is hung from above on a straight barlike member serving as a hinge. The hinge extends from the end plate at the side. This enables the hinge rod to be connected to a damper or crank mechanism for controlled rotation. The end plate welds to a second pipe. This device is conveniently connected in the pipeline by welding to the connected pipes as mentioned above and provides a full opening to enable it to pass a pipeline pig, for example, having the diameter of the pipe.

Full bore pipeline valve apparatus

A three port, two way check valve is disclosed. It is made of a standard tee and standard flanges attached thereto, typically in conformance with API standards. A flat disc is inserted in one of the openings, the disc incorporating an inernal circular valve seat and a hinged valve member which closes against the disc. A similar apparatus is installed in the center port of the tee. The flapper valve elements are connected together by a connecting rod. The connecting rod assures that when one is pulled closed that the other is pulled open. The connecting rod assures that the check valve function is obtained.
