The adhesive bonding strength of a pressure sensitive adhesive on a laminate is selectively modified by applying a discontinuous layer of a non-adhesive material to the pressure sensitive adhesive. Preferably, the laminate is a preformed, label stock, including a label or substrate having a pressure sensitive adhesive on one surface thereof and a release sheet overlying the adhesive. The label is first delaminated from the release sheet to expose the oppositely facing surface of the label and the release sheet. A discontinuous layer of the non-adhesive material is then printed on either the release sheet or the adhesive. The release sheet is relaminated back onto the label to form a modified laminate with new adhesive properties. When the label is then separated from the release layer, the non-adhesive material adheres to the pressure sensitive adhesive to reduce the exposed surface area of the adhesive.

A linerless label product, method of making, apparatus and method for dispensing the product wherein a convolutely wound web roll has one face coated with pressure sensitive adhesive while the other face is coated with a release material, the adhesive is interrupted in longitudinally spaced areas to provide transversely extending bands free of pressure sensitive adhesive with the web areas between bands being labels embodying alpha shapes, numeric shapes, graphics, thermally activated material and/or self-contained material; the preparation method including providing signal-stimulating means for each band and the apparatus and method of dispensing employs sensing of the signal-stimulating means to transversely sever the web in the bands.

A system which detects gas leaks near devices which use “natural gas” or other flammable gases such as methane, ethane, propane or butane and implements multiple automatic responses to the detection of such leaks including emitting audible alarms, contacting utility and emergency service providers, and shutting off the flow of the flammable gases is disclosed. Optional to the system allowing the system to report on the approximate location of the leak and/or the approximate danger level caused by the leak by reporting on the gas/air ratios in the area are also disclosed. A method for implementing the method of the invention is also disclosed.

An apparatus according to which a subterranean formation in which a wellbore extends is hydraulically fractured, the apparatus comprising first and second manifolds, the first manifold including first and second flow lines adapted to be in fluid communication with first and second pumps, respectively, the first pump being adapted to pressurize fluid received from the first flow line, and the second pump being adapted to pressurize fluid received from the second flow line, and the second manifold including a third flow line adapted to convey pressurized fluid from the first and second pumps to the wellbore to hydraulically fracture the subterranean formation in which the wellbore extends. The apparatus is adapted to be connected to another apparatus used to hydraulically fracture the subterranean formation in which the wellbore extends by moving one, or both, of the first and second flow lines relative to the third flow line.
