Patent number: 4215868Abstract: This invention relates to a gasket apparatus for providing a fluid tight seal between a pipe and a porthole in the wall of a manhole riser. The apparatus includes an elongated sleeve of elastomeric material, the sleeve having at one end an outwardly turned, reflexly curved annular flange. The body portion extends axially beyond the flange. A rigid reinforcing ring coaxially engages the inner surface of the flange, forming said flange to a predetermined outside diameter. This apparatus is inserted into the porthole in coaxial sealing relationship therewith. The flange is radially compressed between the ring and the wall of the porthole thereby providing a seal. The end of the pipe is received by the sleeve which is clamped at the distal end thereof onto the pipe to provide a further seal.The method of forming the seal includes inserting a solid, substantially rigid ring into the end portion of an elastomeric elongated sleeve which thereby determines the outer diameter of the sleeve radially opposite the ring.Type: GrantFiled: August 23, 1978Date of Patent: August 5, 1980Assignee: Press Seal Gasket CorporationInventors: Harry W.

Patent number: 4181695Abstract: A method is disclosed to embed a perforated body in a cake of soap and to align that body perforation with a transverse hole in the soap so that a support post can easily penetrate the body hole to support the soap by the embedded body.The flat sheet like body is inserted edgewise into bar soap through a slot in the soap created during the soap extrusion. The problem of aligning the hole in the body with the hole in the soap during the high speed production of cake soap is overcome by first placing the body in the soap at the desired location within a distance of one half the diameter of the hole in the body. The final exact location of the body hole is achieved by a pointed punch creating a hole in the soap by the point on the punch picking up the body hole and shifting the body as needed by a corresponding sized portion of the punch entering the body hole.Type: GrantFiled: January 9, 1978Date of Patent: January 1, 1980Inventor: Glenn E. Rickert

Patent number: 4174913Abstract: An animal guard for use in a field pipe has a generally circular baffle member formed of relatively thin sheet material mounted for pivotable movement in the direction of effluent flow at a perimetral point inwardly of the pipe at an axial predetermined distance from the open end of the pipe. A stop bar is secured inwardly of the pipe at a distance greater than said predetermined distance so that it is on the opposite axial side of the member. The bar extends from the inner surface of the pipe in a direction inclined in the direction of effluent flow and has a length to restrict pivoting of the member in a second arcuate direction oppositely of the first direction to prevent animal entry past the member while the member is free to pivot in the first direction toward the open pipe end to provide substantially free-flow of debris carrying effluents in the pipe toward the open end, while preventing the entrance of animals into the pipe.Type: GrantFiled: November 17, 1977Date of Patent: November 20, 1979Assignee: Myrtle M.

Patent number: 4173814Abstract: A pad, especially an athletic pad, and particularly a pad for use in contact sports to protect the wearer, in which a film of plastic material is deposited on a support and then a body of the same material with a blowing agent therein is placed on the film and the pad member is then cured (gelled and fused) with simultaneous blowing of the added body of material. The pad member is formed so that different regions thereof are different in thickness to provide for increased protection in the thicker regions while flexibility is maintained in the thinner regions of the pad member. The addition of at least one elastic strap element to the pad for retaining it in position on the body completes the construction of the pad member.Type: GrantFiled: July 7, 1977Date of Patent: November 13, 1979Inventor: James H.
