Title: Shaft packing
Inventor: ANDERBERG GORAN
IPC: F16J15/40
Filed: 1991-03-13
Abstract: The present invention consists of a shaft packing with an inner seal (4) and an outer seal (2) which are biased by means of springs (5) and an intermediate ring (1). The spring package and the major part of the shaft packing are positioned on the outside of a wall (20) of a container or the like, on the inside of which container an aggressive medium may be found. On the inside of the wall and in contact with the medium there are only a counter ring (4'), the inner seal (4), the in-termediate ring (1), and a mounting (14). All these parts have smooth surfaces without grooves, notches or the like in order to avoid that the possibly aggressive medium accumulates on the shaft packing. The shaft (19) is journalled in the wall (20) by the mounting (14), and the contact surfaces (22) between the mounting (14) and the wall (20) have circular cross-sections. The mounting (14) is prevented from ro-tating by means of a washer (17) secured to the wall (20) and lowered into a groove (21) on the outer surface of the mounting (14). A flush-ing space as defined between a sleeve (8) fixed on the shaft, the inner sleeve (4'), the inner seal (4), the intermediate ring (1), the outer seal (2) and the outer sleeve (2') for lubrication of the inner and outer seals (2, 4) and their sliding surfaces. The flushing is also intended to re-move particles possibly detached by the rotation of the shaft.

Inventor: LINDAUER JEROME I
IPC: A45D40/00
Filed: 1992-08-31
Abstract: Described is a dispensing unit of a volatilizable substance capable of visible determiation of its extent of use.  The unit has a variably located centroid initially positioned proximate the geometric center point of the unit with the centroid moving downward when the unit is in use.  As the volatilizable substance evaporates, a weight eccentrically located in the same place as the volatilizable substance angularly rotates about the "z" axis leaving its upper position and finally coming to rest at a lower position when the volatilizable material is used up.  At least the final position is rendered visibly detectable by means of a simple sighting mechanism.     Also described are multi-layer, multi-functional volatilizable substance delivery articles.  The articles are constructed in order to deliver, in sequentially-timed fashion, to the environment surrounding the article (e.g., atmosphere, or body of water) different fish feed attractants, repellents, combinations thereof, perfumes having different aroma profiles, insect repellents which repel different insects...during the day time hours and during the night time hours, air freshener-insect repellent combinations, perfume-air freshener combinations and the like.  The article can be constructed where one of the layers is a gel layer and the matrix layer adjacent thereto is composed of perfume-containing particles which emit a fragrance in a sustained release fashion.     Also described is a stick shave formulation and article employing said formulation.  The stick shave formulation contains a triethanolamine stearate soap formed in situ with from 1-10% of a nonionic wetting agent; from 1-15% of a silicone copolymer; from 0.1-1% of a polyoxyethylene polymer slip agent; from 1-30% of a synthetic detergent; from 2-10% of a whitening agent; and 5-20% of emollient moisturizers and hair lubricants.
