Abstract: 1,214,281. Laminated fabrics. G.E. CUSICK. 2 Dec., 1969 [4 Jan., 1969], No. 661/69. Heading B5N. An outer facing fabric is bonded to a backing fabric which is made from a thermoplastic naterial or has a thermoplastic or thermosetting material applied thereto by placing the outer facing fabric on a porous working surface of a hollow container, placing the backing fabric on the outer facing fabric so that the thermoplastic or thermosetting material is in contact with the outer facing fabric, covering the backing fabric and the facing fabric with a flexible, substantially non-porous sheet, developing a vacuum in the container under the porous working surface to apply suction to the non-porous cover sheet so that the backing fabric and facing fabric are pressed together and applying heat to the backing fabric and facing fabric to activate the thermoplastic or thermosetting materials to effect bonding. The flexible cover sheet which may be transparent may be of polyethylene terephthalate, silicone rubber coated glass cloth, silicone rubber foam or P.T.F.E. coated fabric. The outer facing fabric may be a woven, non-woven, knitted, braided or lace fabric made from wool, mohair, alpaca, cotton, silk, acrylic, modacrylic, polyester, viscose rayon, cellulose acetate or triacetate, nylon, spandex, polyethylene, polypropylene or glass fibres. The backing fabric may be a woven, non-woven or knitted fabric of cotton, viscose rayon, wool, silk, hair, acrylic, modacrylic, polyester, cellulose acetate or triacetate, nylon, spandex, polyethylene, polypropylene or glass fibres and may be coated with granules of polyethylene, polyvinyl acetate, polyamides, cellulose acetate, polypropylene, acrylic, polyester or polyurethane materials which may contain plasticizers and which may be applied through screens or from a vibrating container and heated and pressed to ensure good adhesion. Alternatively the backing fabric may be printed with globules of adhesive, e.g. vinyl chloride plastisol, in a discontinuous, intermittently-spaced predetermined pattern. Heating may be effected by conduction, convection or radiation using hot air, dielectric heating or laser beams through the platen. Steam may be applied to the materials before or after pressing. The porous working surface of the container may be of perforated metal, sintered metal, woven metal or metal sheet drilled with holes. Electrical heating means may be placed on top of this surface and covered by a cladding comprising cotton padding and a cloth cover.

Patent FR-2260944-A1 (FR)
Title: Automatic feeder for aquarium - has container tube, plastic discs and leaves, and weight
IPC: A01K61/85
Filed: 1974-02-19
Abstract: The feeder consists of a tube (4) containing food tablets (7) which is attached to a float (2). A boss (3) inside the tube prevents the tablets, which slide down the tube, from falling out at the lower open end. A plastic tablet (4) at the top of the tube is attached by a string (5) passing through a hole in the tablets to a weight (6) hanging in the water below the tube. The tube is fixed on the float in such a way that the bottom food tablet is in contact with the water and dissolves slowly, releasing particles of food which sink through the water where they are taken by fish. As one tablet dissolves, so the next one slides down the tube to take its place, and so on. The tablets are separated by a small plastic leaf, so that the water can only reach the last tablet.

Title: Triiodoresorcinol prepn in higher yields - by iodinating resorcinol with iodine chloride in dil hydrochloric acid
Inventor: GRINEV ALEXEI NIKOLAEVICH
IPC: C07C37/62
Filed: 1974-06-19
Abstract: (I) is prepd. by reacting resorcinol with iodine chloride in a medium consisting of dil. HCl, at 060 degrees C when the resorcinol is directly iodinated. 2,4,6-Triiodoresorcinol is useful as a prepn. for treating mycoses, viral diseases of the eye, skin, mucosa and acute respiratory diseases. In the known methods for prepn. of (I) e.g. by iodinating resorcinol with iodine in the presence of KI the yield is very low, not more than 50%. The method can be used on an industrial scale, and since the process is carried out in an aqueous medium there is no side reaction.

Title: Grain or powder silo - has walls formed by bent panels with joining flanges
Inventor: LAMPSON SERGE
IPC: B65D90/02
Filed: 1974-07-30
Abstract: The silo wall is made up of panels each made of several sheets of metal (3) joined together. Each sheet has, seen in cross-section, a concave profile with a base (4), a side part (5) and a side part (6) both sloping outwards. One of the edges extending lengthwise from the sloping side (6) has a part (7) bent outwards and sloping in the same way as the opposite edge (8) of sheet (3). The panel is formed by juxtaposing the sheets (3) so that the bent back part (7) covers part (8) of the opposite edge of the next sheet. The undulating profile of each panel gives rigidity to the silo. The sheets can be bolted or welded together at points spaced out (9) on the two edges (7, 8).

Title: Gas fired water heater accessory - has condenser coil through which cold water flows to recover moisture from fumes
IPC: F24H8/00
Filed: 1974-11-08
Abstract: The accessory allows a thermal efficiency of approximately 95% to be reached, and consists of a condenser coil (1) through which cold water flows, a trough (3), a drainpipe system (4), and a cowl (2). The condenser coil can be mounted around and outside the fume discharge port, so that the drops of water do not return to teh combustion chamber. The cowl can be pyramic-shaped, with fins (8) on the outside reheating the dried fumes emerging from the condenser. The trough can be slightly wider than the fins, so that it collects all condensate and discharges it by the drainpipe system for use as distilled water. Its axis is slightly inclined to prevent any water collecting in it.

Title: Optical wave attenuator - comprising a lead lanthanum zirconate titanate wafer with attached electrodes, in a Kerr polarising cell
Inventor: HERRIAU JEAN-PIERRE
IPC: G02F1/05
Filed: 1975-05-07
Abstract: The attenuator comprises two polarisers between which is located a lead lanthanum zirconate titanate wafer with attached electrodes so that an electric field can be applied perpendicular to the transmission direction of the attenuator and at 45 degrees to the polarisation direction of one of the polarisers. The novelty is that it includes appts. for measuring the value of flux transmitted by the attenuator, which provides a signal controlling the voltage applied to the electrodes so that the luminous flux transmitted remain constant. The device provides protection for the human eye or photo-sensitive appts. against excessive luminous flux without altering the images perceived. The wafer pref. has the formula (Pb0.91 La0.09)(Zr0.65 Ti0.35)O3.
