Patent number: 5231999Abstract: A comb for separating strands of hair to implement and facilitate highlighting, streaking or frosting is described. The comb comprises first and second rows of teeth which project angularly from a handle portion. The teeth in the first row are spaced to initially part and separate strands of hair during combing. The teeth in the second row are adjacent to the first row or teeth but in staggered relation thereto. The teeth in the second row are also shorter in length than the first row of teeth and tapered to provide a secondary partition and separation of strands confined between adjacent teeth of the first row. Each tooth in the second row is also formed with a hook that projects toward an adjacent tooth for engaging and separating alternate strands of hair from a grouping.Type: GrantFiled: January 24, 1992Date of Patent: August 3, 1993Inventor: Rudolph J. Schroettner

Patent number: 5016925Abstract: A pipe coupling is described comprising a pair of flanged collars, each collar having a sleeve that fits within one end of a pipe and an integral radial flange that extends radially outward of the pipe section circumference. An annular ring gasket is formed or disposed around each sleeve and the gasket is lodged between the inside surface of the pipe and the sleeve. The end of each pipe section which receives the sleeve is then crimped to form indentations in the exterior surface of the pipe, said indentations compressing the gaskets and forming a watertight seal between the sleeves and the end of each pipe section.Type: GrantFiled: April 27, 1987Date of Patent: May 21, 1991Inventor: Paul K.

Patent number: 4933770Abstract: Disclosed is an audio-to-radio and radio-to-audio signal converter and method for interfacing a facsimile machine with a radio transmitter-receiver having a microphone input, an audio output and a push-to-talk relay. The converter provides a first circuit for inputting the output signal of a facsimile machine to the microphone input of a radio transmitter-receiver; a second circuit controlled by the output signal of the facsimile machine for operating the push-to-talk relay of the radio transmitter-receiver; and a third circuit connected to the audio output of the transmitter-receiver for amplifying the audio output signal, and inputting the resultant signal to the facsimile machine. A fourth circuit provides a null feedback that keeps the stronger audio signals from being amplified which may trigger the push-to-talk relay.Type: GrantFiled: February 12, 1988Date of Patent: June 12, 1990Inventor: George H. DeSpain

Means is also provided for introducing air into both the bladder and the air chamber.Type: GrantFiled: March 28, 1988Date of Patent: January 24, 1989Inventor: Ralph H. Lewis
-
Patent number: 4791800Abstract: A roll forming process is described wherein longitudinal areas of curvature are formed in strip material between longitudinal areas of narrower width, the areas of curvature being bowed downwardly from the center toward the longitudinal flat areas. As the strip material is fed progressively through roll forming stations, the longitudinal areas of curvature are formed into areas of lesser curvature and finally flattened to provide strip material having relative flat areas separated by substantially rectangular ribs. The process is one in which areas of curvature are provided to initially gather strip material for use in forming the sides of one or more ribs with little or no thinning of the strip material.Type: GrantFiled: October 26, 1987Date of Patent: December 20, 1988Assignee: Pacific Roller Die Co., Inc.Inventor: Robert D. Alexander

Patent number: 4764346Abstract: A disposable rebreathing canister is disclosed for administering oxygen and anesthesia to patients. The canister essentially comprises a housing for a scrubber, including a manifold plate and a rigid container, and a flexible liner disposed within the rigid container. The liner forms an imperforate barrier between the interior of the rigid container and the manifold plate. A scrubber disposed between the manifold plate and liner chemically reacts with gases conducted to it through one of a pair of coaxial passages formed in the manifold plate. Reacted gases are then moved through a tortuous passage either back to the other one of the coaxial passages or removed through an exhaust port.The interior of the rigid container connects with a source of pressure that allows the flexible liner to be collapsed, thus forcing treated gases, fresh oxygen and anesthesia into the lungs of the patient.Type: GrantFiled: December 9, 1986Date of Patent: August 16, 1988Assignee: Pioneer Medical Systems, Inc.Inventors: Ralph H. Lewis, Barnum B. Lambert

Patent number: 4763830Abstract: A method is described for manufacturing helically formed pipe from strip material. One side of the strip material is formed to provide a first side flange that projects substantially 90.degree. relative to the plane of the strip. The opposite side of the strip is formed with a channel that includes a second side flange that also projects substantially 90.degree. relative to the plane of the strip but in the opposite direction from the first side flange. The strip material is then helically coiled while the first and second side flanges are moved into abutting contact. Pressure is then applied radially of the pipe axis, forcing the contacting edges of the flanges together while the flanges are welded, thus forming a rib with a helical weld seam located at or near the line of neutral forces in the rib.Type: GrantFiled: December 22, 1986Date of Patent: August 16, 1988Assignee: Pacific Roller Die Co., Inc.Inventor: Paul K. Davis

Patent number: 4756217Abstract: A travelling pipe cut-off is described having a pair of knife-edged rollers mounted on a carriage that also supports a cut-off torch. At least one roller is engaged with the smooth surface of the pipe at all times during cut-off, each such roller advancing the carriage while the pipe is being advanced. The two rollers are spaced apart such that, as the bulge of a pipe seam approaches one of the rollers, that roller is moved out of engagement with the pipe, but the other roller remains in engagement. The carriage and cut-off mechanism is, therefore, advanced only by that roller which is engaged with a smooth surface of the pipe.Type: GrantFiled: February 9, 1987Date of Patent: July 12, 1988Assignee: Pacific Roller Die Co., Inc.Inventor: Dennis G. Holmes
