Title: Debossing and perforating a polymeric web
Inventor: CURRO JOHN JOSEPH
IPC: B29C51/22
Filed: 1986-05-30
Abstract: @ A continuous, multi-phase process for debossing and perforating a substantially continuous web of substantially planar polymeric film to coincide with the image of one or more forming structures, each having a patterned forming surface with a multiplicity of holes and an opposed surface. Each forming structure is open from the holes in the forming surface to its opposed surface. The web of film has an indefinite length, a first surface, a second surface and a thickness. The thickness comprises the distance between the first surface and the second surface. The process comprises at least two sequential.forming phases, one of which involves three-dimensional conformance of the web to the macroscopic profile of the forming structure and another of which involves aperturing of the web to coincide with fine-scale apertures in either the same or a separate forming structure. The order in which the phases are carried out will depend upon the properties desired in the resultant macroscopically expanded, three-dimensional, apertured polymeric web. Because the process is carried out in sequential phases, previously incompatible characteristics which could not be provided by prior art single-phase forming processes can now be achieved.

Title: Process for the production of laminated material or laminated workpieces by vapour deposit of at least one metal material on a metal substrate
Inventor: HODES ERICH
IPC: C23C14/00
Filed: 1987-01-23
Abstract: The invention relates to a process for the production of laminated materials in strip form or as strip portions or plates for the manufacture of friction or sliding elements, in particular friction bearings, friction bearing bushes or thrust discs for internal combustion engines, wherein a metal bearing material layer as a friction layer and possibly an intermediate layer or bonding layer is characterised by chemically reactive vapour depositing on the surface of the metal backing member, from one or more melting crucibles, inter alia by means of an electron beam, in a residual gas atmosphere, having a pressure of 10<-2>-10<-3>mbar and including at least one constituent which chemically reacts with at least one of the constituents of the material to be vapour deposited, wherein the material is dispersion- hardened simultaneously with the vapour deposit operation to form at least one chemical compound which is harder than the material to be vapour deposited. The residual gas atmosphere may be oxygen, wet oxygen, water vapour, nitrogen or air. The material to be vapour deposited suitable for forming oxides and nitrides thereof may be aluminium, cadmium, tin, zinc, nickel or copper. The process according to the invention enjoys particular significance in regard to the vapour deposit of dispersion alloys in order in that way to form dispersion-hardened layers of dispersion alloy, for example aluminium-lead dispersion alloy or lead-tin-bronze dispersion alloy.

Title: Incontinence pad
Inventor: ROBINSON RICHARD D B
IPC: A61F13/15
Filed: 1987-09-14
Abstract: An incontinence pad comprises an absorbent core (1) of e.g. fluffed wood pulp within a tissue cover. In contact with each longitudinal side edge (2) of the core is a tow (3) of hydroneutral fibres extending along substantially the entire length of the core. The tows (3) may conveniently be surface bonded tows of polypropylene/polyethylene bicomponent fibres. A liquid impervious layer (4) covers the underside of the pad and extends up the side of the tows (3). During slow rate urine discharge the urine is absorbed directly by the core (1). If a high rate of urine discharge occurs the tows (3) conduct non-absorbed urine away from the point of application to be absorbed along the full length of the core. <IMAGE>

Title: A method of forming a defect mixed oxide
Inventor: DOBSON PETER JAMES
IPC: C23C14/54
Filed: 1987-10-16
Abstract: A method of forming a defect mixed oxide, eg of the general formula LaAbBc07-x where L is a lanthanide, scandium or yttrium, A is strontium, barium or calcium, B is copper, a:b:c is 1:2:3 and 0<x<1 (where x indicates the degree of oxygen deficiency) is described, and illustrated in Fig. 1, in which sources (5a, 5b, 5c, 5d) of gaseous material, for example sources of atomic beams comprising the elements for forming the defect mixed oxide, 5a being a source of oxygen and 5b-5d providing gaseous material of the respective elements to be incorporated in the defect mixed oxide, are directed at a substrate (3) and switched on and off in a predetermined sequence so as to build up layer by layer on the substrate (3) a unit cell of the defect mixed oxide. The sources, may be electron beam evaporators or heated knudsen cells. Alternatively molecular, atomic or ionic beams can be used or gaseous sources of the metals required such as alkyls and hydrides. In one embodiment the switching on and off of the sources in a predetermined sequence builds up layer by layer a unit cell of laz-xBax CuO4 where 0</=x</=1. The substrate may be strontium titanate, barium titanate or silicon. In one solution where the first source, comprises oxygen; the second source is a source of a lanthanide, Sc or Y; the third source is a source of Sr, Ba, Ca, and the fourth source is a source of Cu the fourth and third source are alternately switched on with the first source switched on form alternate first and second layers on the substrate consisting, respectively of copper and oxygen atoms and of atoms of Ba, Ca, Sr and oxygen atoms and then, after a predetermined number of first layers have been formed, shutting of the first source and actuating the second source instead of the third source to form a third layer consisting of atoms of a lanthanide, Sc, Y and, after formation of the third layer, alternatively actuating the fourth and third sources with the first source actuated so as to form further alternate first and second layers to thereby complete a unit cell. In another embodiment using a first source comprising oxygen, a second source comprising lanthanum, a third source comprising a barium and a fourth source comprising copper are used, and with the first source switched on, the fourth source is switched on to produce a layer of copper and oxygen atoms, after which the fourth source is switched off and the second and third sources are switched on to produce a predetermined number of layers each consisting of oxygen, barium and lanthanum atoms, and then the second and third sources are switched off and fourth source switched on to produce a further layer of copper and oxygen atoms. Reflection high energy electron diffraction may be used to provide a signal indicating completion of a layer and this may include control means for controlling switching on and off of the sources. The substrate may be irradiated during formation of one or more of the layers to facilitate formation of the layers(s). <IMAGE>

Patent GB-2206732-A (GB)
Title: Solar cells
Inventor: HOKUYO SHIGERU
IPC: H01L31/0693
Filed: 1988-06-10
Abstract: In the fabrication processes of a solar cell, a first p-n junction having the function of supplying electric power to the exterior of the solar cell is formed in the vicinity of the light receiving surface, while a second p-n junction is provided in a position separated from the light receiving surface. The two p-n junctions are interconnected in anti-parallel, so that, when a reverse voltage is applied to the first p-n junction, the second p-n junction is forward biased to permit current flow therein, thereby preventing the solar cell from breaking down. Since the first and second p-n junctions are integrated with each other, the cost of fabricating the solar cell is decreased and the reliability thereof is improved.

Title: Ring diaphragm pump
Inventor: VON DER HEYDE RICHARD
IPC: F04C5/00
Filed: 1989-05-05
Abstract: In a ring diaphragm pump 1 at least one weakening is provided in the region of a gripping or holding piece 12 to increase the elastic yieldingness of the latter and thereby reduce its resistance to the piston movement. This weakening may be made by a reduction in cross section or by inwardly and/or outwardly shaped areas. The piece 12 may be approximately Z-shaped or S-shaped with two recesses 16, 17 disposed on opposite sides. A sealing ring bead (15, Fig 2) projecting inwardly approximately in the centre area of the ring diaphragm 4 may have one or more inwardly shaped areas to form a space for the displacement of material and also to increase the radial, elastic yieldingness. The ring bead (15) may be somewhat larger radially than the depth which a ring groove (20) in the rolling piston has for engagement, so that on the one hand there is good sealing pressure, but on the other hand only a slight compressive load.
