  • Patent number: 4593227
    Abstract: A cathode ray tube (CRT) mount which eliminates the need for mounting ears and provides for improved alignment of the CRT in the mount by providing a bezel having an opening therethrough for viewing the face of the CRT and a rear support member having an opening therethrough for receiving the rear portion of the CRT with resilient material being positioned on the bezel and the rear support in all areas that contact the CRT. Fasteners are used to urge the bezel and rear support member together to firmly mount the CRT. Means are provided for accurately aligning the rear support member to the bezel.

  • Patent number: 4537266
    Abstract: A portable and compactible scale includes a flexible, compactible bladder providing an interior chamber in which a non-compressible fluid (e.g., hydraulic liquid) is retained. The bladder includes a top wall adapted to support the load to be weighed and spaced-apart support members extend downward from the top wall and terminate short of the bottom wall under no-load conditions. A plurality of spaced-apart, flexible, substantially non-stretchable tendon means optionally can be provided within the chamber to bridge the opposed top and bottom walls of the bladder and thereby impede outward bulging of the top wall during a weighing operation without inhibiting compressive deflection of the bladder.

  • Patent number: 4437461
    Abstract: A valve respirator device for use both on human and on animal patients. The device comprises a housing having an inport, an outport and an exhaust port. The outport is connected to the patient's respiratory system, the inport is connected to a source of air and the exhaust port is open to the surrounding atmosphere. To that end, in alternating succession, first the inport and then the exhaust port is in fluid communication with the outport. A slotted, rotatable valve cylinder is utilized as a means for providing alternating fluid communication first between the inport and the outport and then between the outport and the exhaust port. The device further comprises a metering plate which is interposed in the path of fluid communication between the outport and the other two respective ports. In that regard, the metering plate includes several apertures which regulate the volume and other flow characteristics of air passing between these respective ports.

  • Patent number: 4374239
    Abstract: Described herein is a process for preparing polyarylates which comprises reacting a diester derivative of a dihydric phenol with an aromatic dicarboxylic acid in the presence of from about 10 to about 60 weight percent of at least one particular halogenated and/or etherated substituted aromatic or heteroaromatic compound, at a temperature of from about 260.degree. to about 350.degree. C.

  • Patent number: 4314051
    Abstract: Described herein is a process for preparing crystalline polyarylates which comprises (a) forming a crystalline polyarylate prepolymer having a reduced viscosity of from 0.05 to about 0.4 dl/g by reacting at least one diester derivative of a dihydric phenol with at least one aromatic dicarboxylic acid in the presence of a solvent, at a temperature of from about 250.degree. to about 300.degree. C., and (b) heating the prepolymer so formed below its melting point to form a crystalline polyarylate having a reduced viscosity of from about 0.45 to about 1.2 dl/g.

  • Patent number: 4294957
    Abstract: Described herein is a process for preparing polyarylates of improved color which comprises reacting a diester derivative of a dihydric phenol with an aromatic dicarboxylic acid in the presence of from about 10 to about 60 weight percent of at least one cycloaliphatic, substituted aromatic or heteroaromatic compound, which compounds contain at least one benzylic and/or tertiary hydrogen atom, at a temperature of from about 260.degree. to about 350.degree. C. Optionally, the process may be carried out in the presence of a magnesium, manganese, or zinc catalyst.
