Title: Hydraulic pulse dampener employing stiff diaphragm and nesting member
Inventor: GRAHAM STEPHEN HOWARD
IPC: F16L55/053
Filed: 1984-04-24
Abstract: A hydraulic pulse dampener (10) employs a stiff diaphragm (11) which is placed in contact with the pressurized liquid upstream of e.g. a high pressure liquid chromatograph. The diaphragm (11) is positioned adjacent a receiving member (12) and when flexed due to absolute increases in pressure or to pressure pulses in the liquid, the diaphragm (11) is capable of nesting in the receiving member (12). As pressure increases, the diaphragm (11) gradually deforms and nests in the shaped recess. The material, contour and thickness of the diaphragm are all selected so that the deformation occurs for pressures from near zero to about 1000 psi. The shape of the nesting member may have a central flat portion which contacts the diaphragm (11) first so that nesting spreads from the center outwardly; thereby producing an increasing resistance to pressure rises as absolute pressure increases. The diaphragm dampener may be used in combination with another conventional pulse dampener (29), Fig. 5, or multiple diaphragm dampeners each having different characteristics may be used. <IMAGE>

Title: One transistor-one capacitor DRAM
Inventor: KOYANAGI MITSUMASA
IPC: H01L27/108
Filed: 1984-09-28
Abstract: A DRAM has a plurality of memory cells each formed of a series connection consisting of a capacitor C and a MISFET Q. A first electrode (7) of the storage capacitor (C) is formed on a semiconductor substrate (1) and is electrically connected with one semiconductor region 6 of the MISFET (Q). A semiconductor region (4) which has a conductivity type identical to that of the semiconductor substrate (1) and an impurity concentration higher than that of the semiconductor substrate is used as a second electrode of the storage capacitor (C). Charges to serve as information are stored in the storage capacitor by principally utilizing the charges of an accumulation layer and the space charges of a depletion layer in the region 4. The depletion layer is narrower or removed, and an inversion layer is prevented from developing. The degree of influence of unnecessary minority carriers attributed to  alpha -particles or the injection thereof from a peripheral circuit is reduced, and adjacent memory cells are electrically isolated by the semiconductor region. The capacitor can be formed in a groove in the substrate and it may have further metal plates overlying the electrode 7. A field oxide 2 may be omitted. <IMAGE>

Title: Stabilizing means for ladders
Inventor: SIMPSON IAN
IPC: E06C7/42
Filed: 1984-11-10
Abstract: The invention consists of a stabilizer for ladders, the device is fitted to the base of a ladder, effectively increasing the base area and thereby greatly increasing the safety factor in ladder use. The important feature of the device is the two self locking brackets, each having two hook parts which lock onto the ladder side rails using a revolving motion. The brackets are welded to two box section leg parts which extend forward and are mutually inclined outwards at the forward ends to prevent the ladder slipping or tilting. Due to the self locking brackets the stabilizer can be fitted or removed quickly. The forward ends of the leg parts are connected pivotally by a rod which is flexible and allow one leg to be relatively higher on the ladder side rail to allow for uneven ground. The rod also enables the stabilizer to be folded. <IMAGE>

Title: Toxic waste liquor disposal
Inventor: BURTON WILLIAM ROBERT
IPC: G21F9/24
Filed: 1984-12-13
Abstract: Toxic waste liquors, especially radio active liquors, are disposed in a sub-zone 23 by feeding down a bore hole 20 a first liquid, then a buffer liquid (e.g. water), then the toxic liquors. Pressure variations are applied to the sub-zone to mix the first liquid and liquors to form gels or solids which inhibit further mixing and form a barrier between the sub-zone and the natural waters in the environment of the sub- zone. In another example the location of the sub-zone is selected so that the environment reacts with the liquors to produce a barrier around the zone. Blind bore holes 26, 27 are used to monitor the sub- zone profile. Materials may be added to the liquor to enhance barrier formation. <IMAGE>

Title: Restructured meat products and methods of making the same
Inventor: GAGLIARDI EUGENE DIEGO
IPC: A23L13/00
Filed: 1985-04-04
Abstract: Restructured meat products are prepared from meat parts which are preferably fresh and without the addition of salt, phosphates and/or enzymes before or during the restructuring process. The meat parts are sliced, preferably across the meat grain, into slices which are about 1 to 3mm thick and have a major surface area about as large as the meat parts will permit, generally averaging greater than about 10cm<2>, and the slices are then kneaded together in a mass, which causes the natural juices to exude from the meat surfaces and stick them together by entanglement of the slices. The resultant mass of meat slices is then formed into a restructured meat product.
Patent GB-2158673-A (GB)
Title: Picture transmission system
Inventor: YUASA HIROYOSHI
IPC: G06T9/00
Filed: 1985-04-18
Abstract: A picture transmission system of the present invention is adapted to code picture data by a variable sampling rate coding system to transmit the same. Picture data are stored in a frame memory (16) of a transmission area so that differential values between the same and predictors from a predictive circuit (43) are obtained by a subtracter (41) and compression-coded by a variable sampling rate compression circuit (42) to be transmitted. The compression-coded differential values are expansion-decoded by a variable sampling rate expansion circuit (40) so that original differential values are supplied to an adder (45). The adder (45) adds up the differential values with predictors, to produce predictors for subsequent sampling points. In a receiving area, transmitted codes are expansion-decoded by a variable sampling rate expansion circuit (51), so that the decoded values are added up with predictors from a predictive circuit (53) by an adder (52) to output the original picture data. Preposition prediction and variable sampling rate decoding are thus combined to enable, in the receiving area, automatic correction of compression/expansion errors caused in the transmission area.
