Abstract: A continuous in-line method for forming an airlaid fibrous fluff web adjacent the uppermost and lowermost surfaces of a substantially planar internal reinforcing ply having substantially the same width as said fibrous web, said ply being substantially impervious to the passage of fibers from one surface thereof to the other, in a continuous fiber deposition zone is disclosed. In a preferred embodiment, a unique tissue folding board is employed to permit continuous formation of an airfelt web having a wet strength tissue reinforcing member located approximately mid-way between its uppermost and lowermost surfaces, In the apparatus for forming the web, two adjacent vacuum chambers (26,27) are preferably employed in the continuous forming zone to compensate forthe increased airflow restriction encountered when forming the uppermost fibrous web position over the reinforcing ply and the lowermost fibrous web portion. In a particularly preferred embodiment, the portion of the internal ply (20) relative to the uppermost and lowermost surfaces of the resultant pad may be adjusted by advancing or retarding the position of the folding board (1) within the fiber deposition zone (12).

IPC: H05B3/20
Filed: 1979-06-19
Abstract: In the case of a heating element for electrically heating stairs, floors, concrete elements, etc., a heating surface formed from a heating enamel (7) is used, the electrical current being transmitted via a multiplicity of alternately arranged electrodes (5, 6) on the heating enamel. The electrodes (5, 6) are accommodated in an insulating container (8, 12, 13, 18, 19, 20, 21), which can consist, for example, of a plastic tube. The essential feature is that not just two electrodes are provided on one heating element, but rather a multiplicity thereof, which are arranged alternately on a small space such that the current distribution is even and such that the heating of the heating element is also even. It is particularly simple to arrange the heating enamel (7) on the surface of the particles (15) of gravel or sand ballast (14), the heating enamel merely having to be sprayed on. Such gravel or sand ballast can easily be placed into a container, for example a plastic tube. A flat construction, with the aid of an insulating container formed from edge strips (18, 19, 20) and covering films (21), is also possible. <IMAGE>

Patent EP-0012913-A1 (EP)
Inventor: JONES JR ROBERT EDWARD
IPC: G11B5/31
Filed: 1979-12-10
Abstract: A thin film magnetic head comprises a non-magnetic substrate (10) and a pair of magentic pole pieces (P1, P2) separated by a transducing gap layer (12). When the first and second pole pieces (P1, P2) are of equal width manufacturing deposition variations will result in a tendency for second pole piece layer P2 to overhang first pole piece layer P1, a condition termed "wraparound", causing defective head operation. 
     The method disclosed avoids this problem by selecting the nominal width of the second pole piece layer (P2) to be less than the nominal width of the first pole piece layer (P1) taking into account manufacturing deposition variations to ensure that, when deposited, the second pole piece layer (P2) overlies the first pole piece layer (P1) without overhang, and by depositing the nominal widths of pole piece layers (P1, P2) with the nominal widths so selected. 
     When used for recording on a magnetic medium, the effective width of a data track recorded is slightly greater than the width of the second pole piece layer (P2) and is relatively independent of the width of the first pole piece layec (P1).
