Abstract: A shampooing apparatus or device that is a portable, lightweight, and easily operated for providing automatic shampooing and/or conditioning. The apparatus comprises a body having a dispensing head and adapted to contain at least one but preferably two capsules one of which may contain a shampoo concentrate and the other a conditioner. The body receives these capsules and also receives liquid under pressure from a source of the liquid. In the two capsule version there are separate output ports that couple to a common entry port into a cylindrical cavity of the dispensing head. The dispensing head is of pulsating type including a rotor. In an alternate embodiment in place of the capsules are provided externally disposed containers for the conditioner and shampoo.

Abstract: An improved method for processing the effluent of a hydrocarbon conversion zone. The invention is particularly useful in a catalytic reforming reaction, wherein practice of the invention results in an increased recovery of butane and propane. The effluent is separated into vapor and liquid components, which are then recontacted at a higher pressure. Several recontacting steps may be employed. Liquid product is then subjected to fractionation. Overhead vapor from the fractionation zone is recycled back to a recontacting step in order to recover a portion of the hydrocarbons contained therein, instead of routing the vapor to the plant fuel gas system.

Abstract: Polyurethane reaction injection molded products are prepared which have flexural modulus factors (-20.degree. F./158.degree. F.) below 3.4 and often below 2. They are prepared by employing three different polyols or mixtures of polyols, each polyol having a specified reactivity relationship and are employed within specified solubility parameter relationships. These products also have at least two thermal transition temperatures.
