Title: Method of manufacturing a plastic-coated steel mesh sports face mask
Inventor: MARTINITZ FRANZ W
IPC: A42B3/20
Filed: 1991-12-05
Granted: 1995-11-07
Abstract: A wire mesh face mask for hockey or other sports is manufactured from a steel having carbon content in the range of AISI grades C-1018 to C-1038,and preferably C-1022. The mask is made by forming a grid of generally horizontal wires overlaid by generally vertical wires, shaping the grid into a mask shape, welding the wires to each other where they intersect, heat treating and quenching the grid to increase hardness, dipping the grid to coat it with an epoxy coating. This combination of materials and processes permits the use of a thinner wire than has previously been possible in face masks.

Title: Improvements in or relating to dispensers
Inventor: POOL HAZEL
IPC: B65D83/14
Filed: 1990-05-21
Granted: 2000-02-01
Abstract: Dispensing arrangements, comprising a gas-pressurized container for a material to be dispensed with a valve actuable to open a discharge passage through the valve and through a valve and a valve actuator to an actuator discharge outlet, are well known in the art. The invention proposes a non-liquefied gas-pressurized dispensing arrangement capable of being used with relatively low initial gas pressures, and of discharging a relatively high percentage of the dispenser contents with an acceptable spray pattern. The proposed dispensing arrangement attains these advantages by arranging the cross-sectional area of the valve port (17c) to be many times greater than the cross-sectional area of the actuator outlet (22a). In one recited embodiment the actuator outlet bas a cross-sectional area in the region at 0.049 mm2 whilst the total cross-sectional area of the valve ports, the valve having four ports, is some sixteen times greater.

Title: System for transmitting and receiving video signals using interpolation of adaptive factor
Inventor: MOON HEON-HEE
IPC: H04N7/12
Filed: 1992-05-12
Granted: 2000-07-18
Abstract: A system for transmitting and receiving video signals compressed into frequency band blocks, has an adaptive modulation circuit (410 or 450) and an adaptive demodulation circuit (520, 550). The adaptive modulation circuit (410) receives the signal blocks to obtain a block adaptive factor f1 and an index signal ID1, transmits the index signal ID1 therefor to a channel, interpolates the block adaptive so as to obtain a picture element adaptive factor, and selects a final adaptive factor among the block and picture element adaptive factors according to the video signals of the peripheral signal blocks. The adaptive demodulation circuit (520) converts the index signal ID1 into the corresponding block adaptive factor f1, and interpolates the block adaptive factor to produce the picture element adaptive factor, so as to selectively provide the block or picture element factor according to the video signals of the peripheral blocks.

Title: Flow control system
Inventor: TAYLOR STEPHEN ALAN
IPC: F15C1/16
Filed: 1992-08-10
Granted: 1997-03-18
Abstract: A fluid flow control system in which a vortex valve is combined in series with a non-fluidic control valve. The non-fluidic control valve is upstream of the vortex valve and is so arranged that small changes in its state control the operation of the vortex valve, which provides the major control over the flow of the fluid.  Erosion in the non-fluidic valve due to abrasion or cavitation in the non-fluidic valve is thereby reduced.

Title: Optical connector connecting apparatus and optical connector connecting method
Inventor: ASANO YASUO
IPC: G02B6/38
Filed: 1992-11-18
Granted: 1998-01-06
Abstract: Disclosed is an optical connector connecting apparatus.  In the apparatus, a plurality of fixed optical connectors are mounted on a fixed member in a lined-up manner.  An optical connector containing member having a movable optical connector mounted thereon is supported on a support member through a small-diameter beam.  A moving plate mounted on a base supports the support member, and the movable optical connector is moved in X-axis, Y-axis and Z-axis directions so as to be connected to the fixed optical connector.  Therefore, a position deviation at the time of the connection is corrected by the flexing of the small-diameter beam so that fine-positioning is unnecessary.

Granted: 1997-03-04
Abstract: The foodstuff-displaying refrigerator unit comprises a box-like container, having an enclosure upwardly opening through a top mouth.  A door aperture is defined about a side wall of the container.  A vegetable-supporting platform is freely mounted into the enclosure for vertical movement therethrough.   A pallet is supported by a first conveyor, itself resting on the container flooring.  Inflatable balloons are provided between the pallet and the platform, for power lifting the platform.  An air compressor feeds air into the balloons, and furthermore cools the air within the container enclosure beneath the platform.  The top layer of foodstuff supported by the platform can thus be adjusted by the inflatable balloons, to remain substantially about the plane of the top mouth of refrigerator enclosure, to facilitate inspection of and  access  to  the foodstuff  independently  of  the  level  of progressive  attrition  of  foodstuff  from  successive  foodstuff withdrawal by customers.

Title: Grubber tine
Inventor: SKJ VELAND MAGNE
IPC: A01B61/04
Filed: 1993-07-15
Granted: 1995-12-12
Abstract: The invention relates to a grubber tine of a tubular cross-section which, as compared to known grubber tines, gives reduced weight and larger flexure and vibrations when moved through the soil, which gives reduced tractive power.  The grubber tine is adpated to escape obstacles within the soil in that the grubber tine is pivotally suspended on a shaft.  Boss means is/are attached to the grubber tine through friction forces between boss means and grubber tine at a preferably conical contact face, achieved in that the boss means is/are pressed into holes in the wall of the grubber tine.  In the working position, the grubber tine rests against a shaft and is kept in place by means of a safety bolt adapted to be stretched off upon the occurrence of overload.  The safety bolt may be combined with a resilient member, such that the grubber tine to a certain degree may yield upon load and then return to working position.  Alternatively, the safety bolt may completely be substituted by a biased spring allowing the grubber tine to rotate around the shaft, escaping obstacles and passing over possible obstacles, thereafter returning to working position by means of the spring force.

Abstract: A new seed-specific plant promoter is provided, capable of expressing a gene placed under control of said promoter before or during fatty acid or lipid biosynthesis in plant cells. In nature it occurs in the acyl carrier protein (ACP) gene. This opens the possibility of modifying the fatty acid synthesis in plants, which may result in changing the triacyglycerol composition of oil-containing seeds. Another option is the production of a desired protein in plants, either to improve the nutritional value of the seeds, or for the production of specific proteins that can be isolated from the fruits of plants.

Granted: 2000-02-29
Abstract: The invention relates to a water treatment system and more particularly to a fish tank and biofilter for use in a fish aquaculture. The fish tank has a double outlet system whereby solid waste particles are drawn continually into a central well by a trickle of water flowing through the well and out stand-pipe apparatus exterior of the tank. Clarified water is withdrawn from the center of the fish tank through a manifold having an outlet above the well and conducted to a spray bar of a separate biofilter apparatus. The biofilter includes a rotating spray bar distributing water over a bed of floating media pellets, the water exiting the spray bar causing momentarily and cyclically dynamic flow loading of the bed of pellets below it whereby the pellets are gently agitated. Fine particles in the clarified water to be filtered and biofilter growth particulates gently scoured from the media fall to a cone-shaped bottom of the biofilter tank and gravitate to a central well from which the solid fine wastes can be periodically flushed. The filtered water is returned to the fish tank by a filtered water manifold having an inlet above the bottom of the biofilter tank but below the floating media.
