Patent number: 4487365Abstract: A process for supplying insulating materials wherein fibrous insulating material moves in a confined turbulent air stream into which an adhesive is injected. Air under pressure is also injected so that portions of the air are entrapped within the fibrous insulating material. The injection of the adhesive and the air increases the pressure of the confined moving air stream so that the fibrous insulating material expands and fluffs when released to the atmosphere.Type: GrantFiled: May 19, 1981Date of Patent: December 11, 1984Inventor: Henry V. Sperber

The sensor is a capacitor which extends at least over the entire range of the variable liquid level in the measuring vessel and whose dielectric is the liquid situated in the measuring vessel. A capacitance meter is provided for measuring the capacitance of the capacitor.Type: GrantFiled: July 30, 1982Date of Patent: November 20, 1984Assignee: Jagenberg AGInventor: Gerhard Buschmann

Patent number: 4462511Abstract: A funnel shaped conveyor receives containers of powdered materials and is coupled to the containers. A screen support member within the funnel receives granules from the container and supports the same above a spray nozzle. The nozzle directs a spray of liquid, such as water, against the underside of the support screen and wets the granules resting thereon, dissolving the same and causing the solution to pass through the screen. The nozzle further sprays the sides of the funnel in order to remove any caking material and reduce clogging. A discharge port provides the resulting solution to a receptacle, such as a washing machine. The apparatus includes a dual safety feature, which assures that an operator will not be exposed to any caustic solutions during a change of containers. Rotatable mounting brackets permit gravity fed operation in a first position, and permit container replacement in a second position in which a sensing switch disables the nozzle.Type: GrantFiled: September 21, 1983Date of Patent: July 31, 1984Assignee: Viking Injector CompanyInventors: Frederick J.

Patent number: 4446990Abstract: A device for spraying a noxious powder includes a housing for a CO.sub.2 cartridge, and a moveable barrel which carries a firing pin by which the cartridge can be punctured to explosively release the gas. The barrel has a nozzle at its outer end, and contains the noxious powder in a chamber defined between the barrel and the firing pin. When the barrel is released from an outwardly extended position it is thrust by a spring against the rupturable end of the cartridge, thereby releasing the gas which in turn propels the active agent through the nozzle and toward the assailant at whom it is aimed. Generally, a powdered tear gas will be employed in the device.Type: GrantFiled: April 3, 1982Date of Patent: May 8, 1984Assignee: David J. StevensonInventors: David J. Stevenson, Robert E. Domian
