Abstract: A device that is a handheld circular heating element for use in the construction industry is described. Specifically the device is useful for applying heat uniformly to a two-piece membrane for separation of the outer layer to allow the inner layer to be exposed. The device includes a handle, an electrical supply, an on/off switch and a heating element. The device uses electricity to heat the heat-emitting burner of the heating element, which is then placed next to the membrane. As the membrane is warmed, the two layers of the membrane are able to be separated, which exposes the inner membrane.

Abstract: A system and method of installation for installing a rolled sheet material on a vertical or near-vertical surface are described. Specifically the system and method of installation are useful in the construction industry where heavy rolls of sheet materials must be precisely installed on walls and other vertical surfaces that can be several stories high. The system includes a rolled material spool holder with mounting hardware to allow mounting of the spool holder to a piece of construction equipment along with a spool director, which is also mounted to the piece of movable construction equipment, such as a scissor lift. The method of installation involves positioning the scissor lift along the wall in the desired start location and the desired starting height.

Abstract: A sitz bath helps patients suffering from hemorrhoids and other conditions to void their bowels. A flushing sitz bath utilizes an attached liquid filling tube, integrated water distribution channel and valve, a swing check valve, and a content-emptying flapper valve. This device helps to increase the efficiency of filling the sitz bath basin with the preferred liquid, as well as increasing the ease and cleanliness of the subsequent emptying of the basin contents by minimizing bodily strain and mess.

Abstract: An improved method is described for reducing the nitrogen oxide content of an effluent gas stream wherein the temperature of the gas varies. The improvement comprises alternately, depending upon the temperature of the gas, contacting the gas with(A) formaldehyde when the gas is at an elevated temperature which is sufficient to promote the reaction of formaldehyde with the nitrogen oxide in the gas and to reduce the nitrogen oxide content in the gas to a desired level, or(B) formaldehyde-derived free radicals capable of reacting with nitrogen oxide when the temperature of the gas is lower than the temperature in (A) and the reaction with formaldehyde does not reduce the nitrogen oxide content to the desired level, whereby the nitrogen oxide content of the gas is reduced to the desired level. The free radicals may be generated by reacting formaldehyde with nitrogen or nitrogen oxide in the presence of a catalyst. Preferred catalysts comprise zirconium, cerium, phosphorus, vanadium, or mixtures thereof.
