Abstract: A punctured, substantially deflated pneumatic automotive tire is internally sealed using a specially designed sealant canister containing CO.sub.2 gas propellant and a tire sealant mixture. The canister sealant comprises approximately 97% by weight of an acrylic latex material which is present with the propellant under a pre-use internal pressure of about 55-65 psig. An outlet cone portion of the canister is removably connectable to the tire inflation valve, and the internal volume and pre-use pressure of the canister are related to the internal volume and normal full inflation pressure of the tire in a manner such that the canister is operative to deliver essentially its entire contents into the tire, yet only partially inflates the substantially deflated tire past its initial pressure.

Abstract: A attachment that can be attached to the opening of a container to pressurize the same with a gas. The attachment has a housing which holds a removable cartridge that contains either pressurized nitrogen or CO.sub.2. Extending from the attachment is a button that is connected to a valve which controls the flow of gas into the container. The button and valve are coupled to a spring which functions as a regulator that controls the gas pressure within the container. When the button is depressed, the valve is opened and the gas is allowed to flow into the container. The spring maintains the valve in the open position until the gas pressure overcomes the spring force and closes the valve. Varying the movement of the button varies the spring force and the gas pressure within the container.

Abstract: A dual dispenser dispenses both soap and fragrance for washrooms. The dispenser has a mounting plate for mounting on a surface in the washroom and has a lower support for a box containing a flexible bag of soap with the bag having a flexible tube extending out of the box.

Abstract: The disclosure relates to formation of polycrystalline silicon by the fluid bed process wherein seed crystals of silicon are entered into the reactor from the bottom thereof and by means of a pressurized feed, the product being removed from the reactor through a tube entering the reactor at its bottommost portion. The removed product passes through a closed line by gravity into a closed vessel, the vessel being movable to a crystal puller apparatus without handling or exposure. The closed line is also tapped, as desired, to remove product on-line for test during operation so that the system can be immediately shut down when improper product is detected without excessive loss of pure polycrystalline silicon. The polycrystalline silicon is fed from the transfer vessel to a melt from which crystals are to be pulled via an intermediate reservoir. The silicon is transferred from the vessel to the reservoir under pressure to prevent contamination thereof.
