Patent number: 4243858Abstract: A snap disc operator pressure switch is disclosed in which a thin flexible diaphragm is positioned adjacent to the disc to isolate the pressure chamber from the disc chamber and to transmit the pressure forces directly to the surface of the disc. The disc is positioned in a disc seat and is held therein by the diaphragm. The calibration of the disc is not adversely affected because it is not necessary to provide a seal directly with the disc. The disc seat member is shaped to support the disc against overpressure and to provide a guide for the switch bumper. When higher operating pressures are required, two discs are positioned in the disc seat at face-to-face adjacency and the device operates at a pressure substantially equal to the sum of the calibration pressures of the discs. In another embodiment, the movable arm of the switch is biased closed and is moved to an open position by a spring-biased operator.Type: GrantFiled: January 19, 1979Date of Patent: January 6, 1981Assignee: Therm-O-Disc IncorporatedInventor: Donald E.

Patent number: 4235378Abstract: A water play toy shaped in the form of an animal or cartoon character in which the body is provided with an outlet section which has a plurality of flexible hollow tubes attached to water outlets spaced around the outlet section. A source of water under pressure is coupled to a conduit passing through the body and communicates with the outlet section for distributing water to the hollow tubes. When the water pressure is turned on, a plurality of individual jets of water are emitted by the individual tubes. Because the tubes are flexible they writhe and twist in a random motion pattern due to the action and reaction forces of the water acting on the tubes. In one embodiment a first enclosed chamber compresses the outlet section. A second enclosed chamber is built into the upper interior portion of the first chamber which communicates with a small pinhole-type outlet to provide a misting or fogging aspect to the overall water pattern emitted by the water play toy.Type: GrantFiled: July 16, 1979Date of Patent: November 25, 1980Assignee: Wham-O Mfg.

Patent number: 4233800Abstract: An improved envelope opener comprising first, second and third shear stations for shearing three edges of an envelope in sequence one edge at a time. Each shear station sequentially aligns the envelope by contacting the edge to be sheared, shears the contacted edge, and then releases the envelope. Each shear station includes a self-sharpening and self-aligning anvil assembly comprising a pivotable anvil which is spring-urged to an adjustable home position. The home position of the anvil is adjusted by means of a rotatable eccentric stop. During a shearing operation, the anvil is pivoted away from and then back towards the home position. An overly thick envelope will keep the anvil pivoted away from the home position to avoid a jam condition at the shear station. A peel back station downstream of the last shear station peels back the top panel of the envelope to expose the contents thereof.Type: GrantFiled: December 20, 1978Date of Patent: November 18, 1980Assignee: Amer-O-Matic CorporationInventors: William J.

Patent number: 4234777Abstract: A welding machine includes a programming device to move a welding head relative to horizontal main X and Y axes, and to rotate the head about a vertical C axis. A sensor is connected to rotate with the welding head on a rotator. A sine cosine resolver is mounted on the rotator so that its shaft is geared to the rotator gear. Deviations from the programmed path which may occur in the weld groove are sensed by the sensor, which in turn causes the resolver output to drive a slide mechanism which defines deviation axes X.sub.d and Y.sub.d and which causes the weld head to move from its programmed path to the desired corrected path, when needed. The resolver includes a deviation correction control rotor winding and a second rotor winding, the latter selectively impressing signals on the X.sub.d and/or Y.sub.d slide mechanism drive to cause the welding head to effectively change speed independent of the program or of the existence of any deviation.Type: GrantFiled: August 15, 1979Date of Patent: November 18, 1980Assignee: C-R-O, Inc.Inventor: Fredrick J. Balfanz
