Title: Device suitable for containing a bag holding plant growing medium
Inventor: KIRKHAM PAUL
IPC: A01G9/02
Filed: 1991-01-24
Abstract: A device 20 suitable for containing a bag 30 holding plant growing medium comprises a housing of rigid material. The housing comprises a flat base portion with walls 25b upstanding therefrom and a top portion 21, with an aperture which extends along the top portion 21 from one side towards the other, wherein the cross-sectional area of the aperture is substantially smaller than the cross-sectional area of the top portion 21 as defined by walls 25b. The aperture is defined by a lip 31 which projects towards the base portion and extends into the plant growing medium, such that when the plant is watered, water must flow into the medium. The device 20 therefore provides for plants grown in the bags to be more efficiently watered, and plant supports may be readily attached to the device 20. <IMAGE>

Title: Moulding a magnetic recording head, tape guide cylinder
Inventor: MATSUWAKA TETSUNORI
IPC: B29C45/14
Filed: 1991-07-26
Abstract: An aluminum alloy ring (i2) (the outside diameter D1) which is an element of a rotary head cylinder, is inserted in a cavity (the inside diameter D2 > D1) of a fixed metal mold (10). with a clearance gap (D2 - D1). Then, the cavity of the fixed metal mold is closed by a movable metal mold (11), and the inner space of the aluminum alloy ring is filled with molten synthetic resin of die casting aluminum material (15). The filling material e.g. resin. is pressurized so that the aluminum alloy ring elastically expands until the outer diameter thereof D1 becomes exactly or almost equal to D2. After that, the filling synthetic resin material is cooled. Thus, the aluminum alloy ring (12) and the synthetic resin material are integrated, resulting in a rotary head cylinder molding. <IMAGE>

Title: Minutely roughening substrate surface by etching
Inventor: ITOH TOSHIAKI
IPC: C04B41/00
Filed: 1992-08-28
Abstract: A method of minutely roughening a surface of a substrate such as glass, ceramic, metal or resin for the purpose of enhancing the adhesion of a coating film to the substrate surface or preventing the sticking of certain articles to the substrate surface such as with glass plates for electrophotographic copying machines or as with a magnetic disc for a computer, is provided. An easily vaporizable material such as a fat or wax is used as a masking material, and the substrate surface is scattered with numerous microscopic droplets of the masking material by exposing the substrate surface to vapor of the masking material and simultaneously to vapor of another material, e.g. water or an alcohol, which is immiscible with the masking material and serves the purpose of preventing agglomeration of droplets of the masking material on the substrate surface. The substrate is subsequently etched with an etching fluid and the masking material is removed.

IPC: A61F5/44
Filed: 1993-01-06
Abstract: The present invention relates to an absorbent article for one-time use only, such as a disposable diaper, incontinence guard, sanitary napkin, panty's protector or the like. The inventive article is characterized in that it includes at least one hose-like fold (20, 20', 21, 21') which extends in the transverse and/or longitudinal direction of the article. Mounted in the fold (20, 20', 21, 21') are mutually spaced elastic elements (32, 32', 33, 33') which are fastened to respective end-parts (27, 27', 28, 28') of the fold on respective sides of fold lines (24, 25) which depart from the upper casing layer (1) of the article, although these elastic elements (32, 32', 33, 33') are freely moveable in the intermediate part (29, 29') of the fold. The end-parts (27, 27', 28, 28') of the fold are joined to the upper casing layer (1) in a flat, permanently down-pressed state, whereas the intermediate fold part (29, 29') is forcibly lifted vertically by the action of the elastic elements (32, 32', 33, 33') as the article is fitted to the wearer and consequently curved, so as to form leakage barriers along the side-edges and/or the end-edges (4-7) of the article.

Title: Wind-resistant roofing elements
Inventor: CHILDRESS PAUL VINCENT
IPC: E04D1/16
Filed: 1993-05-19
Abstract: Roofing elements 2, particularly suitable for use on flat roof constructions, are provided with co-operating means on each of at least one pair of opposite side edges 12, 14 for cooperation with at least two adjacent elements on each of the side edges. When assembled, movement of any one element involves movement of at least one co-operating element on each of the opposite sides edges. Such bidirectional co-operation results in an interlocked roof construction wherein the uplifting of individual roofing elements by the action of the wind or other forces is substantially eliminated. Uplift pressure caused by wind passing over the roof surface can be further reduced by providing communicating air-flow passages between co-operating elements. Typically the elements overlie a water proof membrane on a flat roof, and the protruding lugs of a tile fit into recesses 20, 22 of adjacent tiles; the lugs may be at one end as shown, central, or at both ends of a tile. The tile may have grooves and/or insulating material underneath. <IMAGE>
