Filed: 1992-05-25
Abstract: PCT No. PCT/GB90/01746 Sec. 371 Date Apr. 16, 1992 Sec. 102(e) Date Apr. 16, 1992 PCT Filed Nov. 13, 1990 PCT Pub. No. WO91/08398 PCT Pub. Date Jun. 13, 1991.A load indicating fastener such as a bolt (10) or stud, has a shank (12) which is subject to tensile loading in use. The shank (12) has an axially extending bore (22) which receives a first gauge pin (30) anchored at its inner end (32) to the shank (12) and protruding outwards beyond an end face (16) of the fastener. An indicating member (40) is rotatable on the protruding portion of the gauge pin (30) between the end face (16) of the fastener and the head (34) of the pin (30), so that the indicating member (40) is free to rotate when the shank (12) of the fastener is unstressed but when the shank (12) is subject to a predetermined tensile loading is held against rotation by contact with the end face (16) of the fastener. A second gauge pin (42) is received within an axially extending bore (36) in the first gauge pin (30) and is anchored at is inner end and protrudes outwards beyond the outer end of the first gauge pin (30). A second indicating member (50) is rotatable on the protruding part of the second gauge pin (42), between the head (46) of the pin (42) and the first indicating member (40). The second indicating member (50) is free to rotate when the shank (12) of the fastener is unstressed or subject to the first predetermined loading, but when the shank (12) is subject to a second predetermined tensile loading greater than the first predetermined loading, the second indicating member (50) is held against rotation by contact with the first indicating member (40). The first indicating member (40) provides an indication when the fastener has been tightened to a desired loading. The second indicating member (50) provides an indication when the fastener has been overloaded.

Title: Filter and installation means for dry material filter for electric vacuum cleaner
Inventor: BERFIELD ROBERT C
IPC: A47L9/10
Filed: 1989-12-18
Granted: 2002-04-16
Abstract: For installing a dry material paper filter on the filter cage of an electric vacuum cleaner, a disk of porous paper filtering material or of cloth type fabric is laid over the panel enclosing the bottom of the filter cage and a ring is pressed up over the paper or cloth filter and over the panel. As the ring is drawn up over the filter cage, it folds and presses the paper or cloth filter around the filter cage. At the top of the filter cage, the ring secures the filter to the cage. An additional filtering sleeve may be disposed around the filter cage before the filter is installed over the cage and over the sleeve with the attachment ring. The sleeve may be of foam or other wet material filtering material. The filter installed with the ring is of dry filtering material, like paper or cloth. A marking or disk at the center of the fil-ter helps a user place the filter over the filter cage before the ring is used to fold the filter into place.

Title: Tumble method of rinsing fabric in a horizontal axis washer
Inventor: EULER JOHN W
IPC: D06F35/00
Filed: 1992-12-23
Granted: 1999-11-02
Abstract: The present invention contemplates a rinse process which can be used with any wash cycle, but which has particular utility following a wash cycle have a highly concentrated detergent solution.      The method of rinsing fabric provided by the present invention is useful in a washer having a wash chamber rotatable about a horizontal axis. The steps undertaken in the method begin with loading fabric to be washed into the wash chamber of the washer. The fabric is then washed in a detergent solution while rotating the wash chamber about its horizontal axis for a first period of time. Next the detergent solution is drained from the wash chamber. The fabric is then rinsed by adding water to the wash chamber while spinning the wash chamber at a speed to effect less than a one gravity centrifugal force on the fabric such that the fabric will tumble within the wash chamber as it spins. Finally, the wash chamber is drained of the rinse water.

Granted: 1995-11-21
Abstract: An exhaust pipe assembly is provided for achieving a quick light-off of a catalytic converter.  Exhaust pipe assembly comprises circuitously bent inner and outer pipes disposed in generally concentric relationship to one another.  The inner pipe is formed from a very thin metal to provide a low thermal mass and a correspondingly low heat dissipation therefrom.  The outer pipe is thicker to provide structural support,  and defines an air insulation barrier around the inner pipe to further reduce heat dissipation.  The inner pipe is corrugated at selected locations that will correspond to bends  in the circuitous exhaust pipe assembly.  The thin-walled locally corrugated inner pipe is then inserted into the outer pipe, and the assembly is bent into the required configuration.   The corrugations support the inner and outer pipe relative to one another during the bending process and during use.   The bent pipe assembly then is connected to the catalytic converter for subsequent mounting to vehicle engine.
