An insert fastened to a panel is secured to the panel by forming on one end of the insert and by bonding with an adhesive on the other end. The working end of the anvil presses against the insert during forming and the flowing compressed air blows excess adhesive from the contacted surface of the insert.Type: GrantFiled: September 6, 1979Date of Patent: December 30, 1980Assignee: The Boeing CompanyInventor: Elvin G.

Patent number: 4081382Abstract: An apparatus for separating particulate solids from liquids includes a blower which is mounted for rotation between two upright walls. A sieve surrounds the rotor with a spacing therefrom and a solid-liquid mixture to be separated is introduced onto a portion of the sieve. The flow of gaseous medium advanced by the blower is directed onto the sieve by an elongated curved guide element having one end close to the portion of the sieve, another end close to the blower in the region of the first-mentioned end, and a curved portion extending from the one to the other end around the blower opposite to the direction of rotation of the blower at a decreasing distance from the latter. The guide element bounds with the sieve a passage the flow-through cross section of which decreases in the direction of advancement of the gaseous medium which thus partly propagates along the passage and partly escapes therefrom through the sieve and thus entrains and expels the liquid from the mixture through the sieve.Type: GrantFiled: April 28, 1977Date of Patent: March 28, 1978Assignee: Maschinenfabrik Buckau R.

Patent number: 4003226Abstract: An air blast dust removal machine has a jet of air projected from at least one slot-like nozzle inclined at an obtuse angle towards an oncoming sheet material which is held to a moving permeable conveyor belt. The sheet material is held to the conveyor belt by at least one suction device desposed on the opposite side of the conveyor belt as the sheet material passes adjacent the jet of air. A second conveyor belt holds the sheet material from its top side by a suction device; and an obtusely projected jet of air blasts dust from the bottom side of the sheet material.Type: GrantFiled: April 7, 1976Date of Patent: January 18, 1977Assignee: USM CorporationInventor: Eric Holdsworth

Patent number: 4003101Abstract: A film support member having a rectangular aperture is provided in contact with the surface of a film to be dried. A compressed air supply device is provided to supply air along the surface of the film from one edge of the reactangular aperture of the film support member. The edge of the aperture is tapered at an angle of 45.degree. or less to guide the air from the air supply device along the surface of the film to have the air uniformly distributed over the film.Type: GrantFiled: January 27, 1976Date of Patent: January 18, 1977Assignee: Fuji Photo Film Co., Ltd.Inventor: Eiichi Saito
