Patent number: 3989228Abstract: A static mixing chamber for mixing multi-component compositions has the provision of having the mixing chamber at the outlet of the feed lines. A valve is at the outlet end of the chamber. By having the chamber near the outlet end, a large pressure drop across the chamber is insured. Moreover, the valve at the end of the chamber insures that the large pressure drop will be maintained even during start-up of dispensing. By increasing the pressure drop over the chamber, mixing therethrough has been greatly enhanced. Therefore, a smaller mixture is required for effective mixing. The result in small size makes the static mixer capable of being hand held, in the form of a dispensing gun and the valve actuator is part of the dispensing gun so that the valve can be operated by the same hand that is holding the gun.Type: GrantFiled: August 26, 1975Date of Patent: November 2, 1976Assignee: Products Research & Chemical CorporationInventors: Lester Morris, Dennis Perkins

Patent number: 3986365Abstract: There is disclosed a composition which is useful, when added to soil, in containing water, said composition containing bentonite and a particular type of water-soluble polymer, the purpose of the water-soluble polymer being to decrease the amount of bentonite necessary to form a water containing enclosure made of soil. The amount of bentonite necessary in the present invention is at least 50% and, most often, 60% less than is necessary when no water-soluble polymer is present. The water-soluble polymer is preferably polyacrylic acid, water-soluble salts of polyacrylic acid, polymethacrylic acid, water-soluble salts thereof, and acylic copolymers formed from either acrylic acid or methacrylic acid. The invention also includes a method for containing water which includes admixing an effective amount of bentonite and water-soluble polymer with soil and forming a water-containing enclosure from said mixture.Type: GrantFiled: January 19, 1976Date of Patent: October 19, 1976Assignee: American Colloid CompanyInventor: John Hughes

Patent number: 3984990Abstract: Improvements in support means for well risers wherein the risers extend through a rotary table on a floating vessel down to a subsea well. A spider supports the upper end of the riser and hydraulically operated gimbal means support the spider with respect to the table to maintain a constant load on the riser. Inertia absorbing means is associated with the gimbal means so that, when sections or buoyancy chambers or the like are added to the riser and it is lowered down to the well, or vessel movement takes place, any off-center load that is acting on the spider that is not equally distributed, the inertia absorbing means absorbs such load and equally distributes it so as to maintain a constant load on the riser.Type: GrantFiled: June 9, 1975Date of Patent: October 12, 1976Assignee: Regan Offshore International, Inc.Inventor: Howard W.

Patent number: 3981535Abstract: A safety belt system includes a continuous loop of webbing which is anchored at one end to the vehicle floor and anchored at the other end to the roof or upper part of the vehicle. A buckle is mounted on the other side of the seat from the first-mentioned floor anchor, and a connector which is positionable along the webbing includes a tongue plate which mates with the buckle. The system has been improved by the provision of the combination of including limiting means on the connector for allowing the webbing to pass only in a direction to shorten the portion between the floor anchor and the buckle over the lower torso of the user and to lengthen the portion of the webbing between the retractor and the connector over the upper torso. The retractor is more powerful than a normal retractor to pull the webbing through the limiting means. The retractor may further include a tensionless feature to relieve the force from the retractor on the webbing.Type: GrantFiled: May 27, 1975Date of Patent: September 21, 1976Assignee: American Safety Equipment CorporationInventors: Cyril Henderson, Albert R. Close

Patent number: 3976450Abstract: A gas sample flowing through the lower chamber of a diffusion cell diffuses through a membrane into the upper chamber at a rate above a determined minimum. As the sample diffuses through the membrane, substantially all of the water and any particulates are removed from the gas. A clean carrier gas flows through the upper chamber at a constant rate to dilute the diffused gas and convey it to gas analyzers. Upon acquisition, a gas sample is maintained at a temperature above its dew point until it passes from the lower chamber and the membrane is maintained at a substantially constant temperature.Type: GrantFiled: July 23, 1974Date of Patent: August 24, 1976Inventors: Roland Marcote, Steve Eisenberg, Ramesh Chand, Herman Haase

Patent number: 3976986Abstract: A battery operated emergency lamp is provided for connection to a normally "on" electrical source of power, such as a standard ac line voltage, where such source is subject to occasional power failures. A solid state switching circuit including a single transistor and one diode serves to maintain the lamp in an unenergized condition and to simultaneously generate a low charging current for a re-chargeable battery so long as the power source remains "on." In the event of a power interruption, the solid state switching circuit is immediately responsive to switch to a condition in which the lamp is energized by the battery current. In one embodiment disclosed herein, the emergency lamp takes the form of a relatively small, portable lantern or flashlight equipped with a standard utility plug for connection to a household electrical outlet.Type: GrantFiled: December 20, 1974Date of Patent: August 24, 1976Inventor: Stanley E. Zabroski

Patent number: 3970507Abstract: A tape dispenser for use in winding tape about a rotating body generally includes a frame mounted on a base with adhesive tape mounted on a reel on the frame. The tape is run from the reel to a holding means which in the preferred form is a vacuum surface which holds the tape thereon but permits it to slide along the surface. The tape is fed in a manner in which the adhesive side faces outward from the vacuum surface. The dispenser has displacement means which pivots the frame and moves it toward the rotating body until the body touches the adhesive of the tape at or near the vacuum surface. The rotation of the rotating body causes tape to be payed from the reel until a predetermined length of tape is wound around the body. Thereafter, it is cut between the body and the vacuum surface.Type: GrantFiled: October 17, 1974Date of Patent: July 20, 1976Assignee: TRW Inc.Inventors: Chester G. Dalzell, Burton D. Pace
