IPC: C09J7/02
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a tacky tape or sheet capable of extremely readily and precisely performing the so-called trimming operations to remove a tacky agent layer in an unnecessary part and form only the tacky agent layer of a required shape. SOLUTION: The top surface of a temporary substrate having mold releasability is coated with a curable type tacky agent convertible into a nontacky state by ultraviolet irradiation in the form of dots to form a tacky agent layer. A masking material prepared by forming a pattern capable of hiding a required tacky agent layer and transmitting ultraviolet rays therethrough only in an unnecessary tacky agent layer part is then laminated onto the tacky agent layer. The masking material is then exposed to the ultraviolet rays from the upper side to convert the unnecessary tacky agent layer part into a nontacky state to peel the masking material from the tacky agent layer.  A sheet of mold release paper having smaller mold releasability than that of the temporary substrate is subsequently laminated onto the tacky agent layer peeled from the masking material and only the required tacky agent layer is transferred onto the mold release paper.

Title: Gas range
Inventor: HANSU ZONMAA
IPC: F24C3/08
Filed: 1981-10-23
Abstract: A cooking station for gas ranges whose burner works with super-stoichiometric combustion air premixing. The burner head arranged in a burner tray is connected with a mixing pipe via a ceramic insulating ring. Between the burner head bottom and the burner head lid with the flat topside, we have two perforated flame opening rings which are arranged concentrically with respect to the burner axis, which are resistant to heat and which are resistant to oxidizing and reducing atmospheres. The perforation of the inner flame-opening ring is so dimensioned that the flames cannot backfire. Below the burner tray there is arranged a reflector. The cooking station can be covered with a glass ceramics plate. The invention achieves stable flame performance, perfect combustion, and waste gas poor in harmful substances at nominal load and at small adjustment heat load within a vast utilization field of gases with differing Wobbe indexes as well as a start-up cooking efficiency improvement compared to known burners.
