Abstract: The present invention is directed to a smoking pipe having an elastic body that defines an air passage. Preferably the elastic body is formed of a heat resistant silicone. The elastic body included a bowl receiving portion and a stem which define an air passage. The bowl receiving portion also including a groove formed at the proximate to the first end of the air passage and an elastic lip formed adjacent to the groove. The bowl may be removably positioned within the bowl receiving portion with the flange seated in the groove and the elastic lip holding the flange compressively within the groove. The bowl may be formed of stainless steel, brass, titanium, glass or ceramic.

Abstract: A hookah bowl, hookah utilized the hookah bowl, and process for using a hookah is disclosed. The hookah bowl includes two principal members, a bowl shell and an adjustable bowl burner that alters its position within the bowl shell. The bowl burner may adjust its position longitudinally, radially, or both.

Abstract: Secondary smoke is harmful to passive smokers. A filter sleeve (1) comprises a sleeve (10) with a downstream portion (11) adapted for receiving inhale smoke into an inhalation flow path (13), an upstream portion (12) adapted for inhalation of said inhale smoke and for receiving exhale smoke into an exhalation flow path (14), filter means (15) provided along said exhalation flow path (14), and means (16) for checking reverse flow of ambient air through said exhalation flow path (14). A filter sheath (3) is adapted for overlaying a significant expanse of the sidestream smoke emission areas of a rod of smokable material (7), said filter sheath (3) is sufficiently porous and significantly unimpaired by combustion.

Abstract: A cigarette holder completely encloses the lit end of a cigarette providing purification for both sidestream smoke and mainstream smoke. It has two concentric tubes with the lit cigarette placed in the inner tube and purifying agent placed in the volume between the inner tube and the outer tube. A chimney effect is produced wherein air flows through an air port past the lit cigarette to keep it burning. The sidestream smoke passes through the purifying agent and is discharged into the environment. The filter tip of the lit cigarette extends through a mouthpiece and the smoker exhales smoke through openings in the same mouthpiece. The mainstream smoke passes through the same purifying agent, in a direction opposite to the flow of the sidestream smoke, and is then discharged into the environment.

Abstract: An exhaust gas scrubbing device has a first chamber having an exhaust gas inlet. A second chamber has an exhaust gas outlet. A partition separates the first and the second chamber. A liquid is contained in the first and second chambers. A conveying device extends through the partition and is immersed in the liquid within the second chamber. The first and second chambers communicate via the conveying device. The exhaust gas, introduced into the first chamber through the gas inlet, is guided through the conveying device and through the liquid contained in the second chamber to the gas outlet and is scrubbed by passing through the liquid.

Abstract: A mild, alkaline permanent wave reducing composition and method of permanently waving or reshaping human hair that provides a strong, long lasting curl like an alkaline permanent wave composition but leaves the hair soft like an acid permanent wave composition and leaves essentially no post-perm odor. The composition contains about 2.0% to about 6.5% by weight of a cysteine reducing agent compound selected from the group consisting of cysteine, a cysteine salt, and mixtures thereof; about 4.5% to about 8.0% of a thioglycolate; and sufficient additional alkali, if necessary, to bring the pH of the composition within the rang of about 7.5 to about 9.5.

Abstract: A tobacco pipe is provided having a bowl, stem and filter. The filter is inserted into the bowl. The filter is substantially cylindrical in shape having a perforated foil cap located on top of the filter. Associated with the filter is a pull wire so that the filter can be retrieved by the user. The filter removes condensed liquids containing tar and nicotine and also filters the smoke.

Abstract: Jewelry smoking devices are described which are in the form of ornamental pipe members suitable for being worn as items of jewelry. Each smoking device has a tobacco receiving portion for receiving smoking tobacco for the purpose of burning the same, and conduit means for carrying smoke from the tobacco receiving portion to a mouthpiece. The devices are in the general forms of pipe rings, pipe bracelets, and the like, and are decorative as well as being functional pipes which can be smoked as normal pipes are or while worn as items of jewelry.

Abstract: An anti-pollution combustion device has a bowl in the interior of which is located, above the connection between the bowl and stem, a perforated metal disc so that the tobacco rests on the same. The outside of the bowl is formed with circumferentially extending cooling ribs. The inside of the bowl is lined with a material which prevents the wood of the bowl from charring. In the smoke passage of the stem is incorporated a filter which can be changed when it is saturated with contaminants. Near the rear end of the stem there is provided a trap with a reservoir in which liquid is trapped and accumulated so that from time to time it can be discharged from the reservoir. The rear end of the stem is provided with a mouthpiece having an annular member projecting transversely of the elongation of the stem and large enough to securely retain the mouthpiece between the teeth of a user, even if the user should have false teeth.
