Title: Personal trainer
Inventor: SMITH FRED T
IPC: A63B21/018
Filed: 1994-09-09
Abstract: A pair of pivotable arms in a clamp in a personal trainer may be spring biased to a closed position as on a door frame. A lock retaining the clamp in the closed position includes a member manually actuatable to release the clamp from the door frame. A clasp on the clamp holds a first belt in a wrapped and frictional relationship.  In one embodiment, the second end of the first belt is retained by a resistance unit which is disposed on a handle adapted to be manually gripped by the user. The resistance unit has bars which receive the belt in a frictional and tensioning relationship to retain the belt. Collars on the handle retain a harness shaped to envelop the user's face. The harness may be moved or rotated relative to the handle to exercise muscles in selective portions (e.g. neck or back) of the user's body. In another embodiment, a second belt engaged by the resistance unit extends beyond the resistance unit. At its extending end, the second belt is looped upon itself to define a stirrup for receiving the user's foot. When the foot is disposed in the stirrup, variousexercises may be performed by gripping the handle, tensioning the second belt on the handle and alternately raising and lowering the handle. Tensioning the second belt on the handle provides resistance in the resistance unit as the handle is moved upwardly and downwardly on the belt, the resistance magnitude being dependent upon the tension magnitude.

The second sealing portion is disposed across the container opening when the safety seal is placed into the opening, and provides an aperture for sealing engagement with the dip tube. The safety seal is resistant to the effects of vibration or other factors that would cause a backing-off or negative rotation of the cap portion of the sprayer mechanism with respect to the neck portion of the container to which it is secured.
Patent CA-2174585-A1 (CA)
Title: Isocyanate compositions and cellulose products impregnated with the compositions
Inventor: PARK DAVID W
IPC: C08K5/10
Filed: 1996-04-19
Abstract: The invention is directed to a composition of matter useful as a paper impregnant, to the method of its use, and to the products produced by the method. Poly (diphenylmethane diisocyanate) or PMDI has been used in the past as a paper impregnant with or without propylene carbonate as a diluent. These products have generally required pressing under high pressures and at elevated temperatures. It has now been found that triacetin and/or triethyl citrate in usages up to about 20% of PMDI give superior performance in impregnated products. The modified PMDI will cure at essentially ambient conditions in times as short as 1-2 days to insoluble polyureas with low residual amounts of isocyanates and reaction byproducts such as 4,4'- diaminodiphenylmethane. The treated papers can be used in applications of which skins for sandwich panels and high strength corrugated board would be exemplary.
