Abstract: This invention relates to a polymer blend comprising in weight percent:A. from about 55% to about 90% of a polymer composition comprising: (i) 75% to about 100% of a homopolymer or a copolymer of polypropylene; and (ii) from about 0% to about 25% of a vinyl aromatic polymer;B. from about 0.5% to about 9% of at least one block polymer of a vinyl aromatic monomer and an aliphatic conjugated diene, a selectively hydrogenated derivative thereof, or a selectively hydrogenated derivative thereof to which has been grafted an unsaturated carboxylic reagent, wherein the block copolymer contains up to 50% by weight bound vinyl aromatic monomer;C. from about 2% to about 12% of at least one block polymer of a vinyl aromatic monomer and a conjugated diene, a partially hydrogenated derivative thereof, or a selectively hydrogenated derivative thereof to which has been grafted an unsaturated carboxylic reagent, wherein the block polymer contains greater than 60% by weight bound vinyl aromatic monomer;D. from about 0.

Abstract: Method and apparatus for controlling the exit velocity of solid/gas carbon dioxide spray cleaning systems. By increasing the pressure of liquid carbon dioxide in the supply line, typically in the range of 800-875 psi, to greater than 875 psi, preferably 2,000-5,000 psi and above, the velocity of the spray stream exiting the nozzle is increased enabling removal of contamination (oils, fingerprints, particles, graffiti, etc.) not removable with a spray stream using conventional carbon dioxide pressures. The apparatus includes the incorporation of a high-pressure pump in the liquid carbon dioxide supply line in combination with a nozzle having a first or inlet orifice smaller in diameter than the supply line and a second or exit orifice larger in diameter than the inlet orifice.

Abstract: A system and method periodically sample a fluid stream in a conduit for undergoing analysis thereof. A sampling tube having a probe is joined to the conduit for removing samples from the stream flowing therethrough. An analyzer is joined to the sampling tube for analyzing the removed samples. A solenoid valve is disposed in the tube for controlling flow of the samples to the analyzer. A dynamic pressure transducer is joined to the conduit so that a specific dynamic pressure reference frequency of the stream in the conduit may be locked-on to and used for periodically switching the solenoid valve open and closed for intermittently removing stream samples from the conduit at the reference frequency for channeling to the analyzer periodic stream samples at a sampling frequency corresponding to the reference frequency.

Abstract: A bottle uses a sleeve to stabilize it when in the inverted position. The sleeve in normally around the middle of the bottle when the bottle is upright. The bottle has a lock for the sleeve which is a thickened area of the bottle sidewall. When one wishes to invert the bottle, the lock is pushed inwardly and the sleeve is slid upward over the lock and its top edge is above the bottle top. The top edge is what provides a stable base to support the bottle when it is inverted. The sleeve is maintained in this extended position by the lock pressing against the sleeve due to the resiliency of the bottle.

Abstract: An improved golf practice device that is able to train all aspects of the golf game. It is a simple tubular structure that can hold and guide the different parts of the body to get the proper feel of putting, chipping, pitching, full swing and bunker shots. The practice aid is of lightweight construction and capable of easy disassembly for portability.
