Abstract: A novel two part punch stripper (10) for use with punches (12) carried by a punch press (16).  The novel two part urethane punch stripper of this invention includes generally cylindrical concentric tubular upper and lower parts (50 and 52).  The lower part (2) is formed of a urethane of a conventional hardness for a punch stripper, the hardness being in the range of 80A to 100A (Shore). The tubular upper part (50) is formed of a urethane substantially harder than the lower part of the stripper, for example, in the range of 75D (Shore).  The combined length of the upper and lower parts is greater than the length of the portion of the punch which extends below the punch retainer assembly (14) so that a proper preload can be achieved.  The upper part and lower parts are bonded to each other by a suitable adhesive.  Alternatively, they may be bonded to each other by sequentially casting in a common mold.

Patent CA-2142486-A1 (CA)
Title: Ventless drain trap
Inventor: CINKANT ANTHONY A
IPC: E03C1/29
Filed: 1995-02-14
Abstract: In a sanitary drain system in a house or other building, there exists a number of fittings called P-traps. There is one at each fixture. (ie. sink, tub, etc.).      A P-traps purpose is to hold back a small portion of water to block the drain system at the fixture.  This blockage stops sewer gases and odours from returning back through the fixture into the house or building.      In order for the P-trap to function properly it requires an air vent to be connected to the drain system about 12 inches downstream from the P-trap, the air vent serves to equalize the atmospheric pressure changes that occur within the system when water is flowing through it (ie. emptying a sink). Without the air vent the small portion of water (the trap is supposed to retain) is drawn out by a syphoning effect caused by the velocity of the flowing water when for example emptying a sink. This allows sewer gases to return through the dry trap and out through the sink.      As an alternative to the P-trap this invention directs the water into a retaining chamber which is larger than the drain pipe system downstream from the chamber.      This chamber being larger causes the velocity of the water to decrease as it flows through it, this allows gravity to capture the water in the chamber and results in air bubbles passing through the water to relieve the syphoning effect, and a portion of water remains in the chamber to create the trap. Hence this invention does not require an air vent.

Abstract: A beer crossflow-microfiltration process is disclosed. In order to avoid fouling of the filter module membrane by the ingredients of the non-clarified beer to be filtered out and that form a covering layer on the membrane, filtration is interrupted from time to time. During a following short pause, the covering layer on the membrane is chemically dissolved with lye, and the covering layer is removed by backflushing the membrane with water. In order to improve filtration, the transmembrane differential pressure (p) is controlled during the filtration phase according to a substantially periodical time function and the flow velocity (v) of the beer through the membrane is substantially continuously increased.
