Title: Garment-shaping device
Inventor: WEBB JEFFREY NORMAN
IPC: A41B9/04
Filed: 1995-09-01
Abstract: A garment-shaping device, particularly for use with close-fitting ladieswear, comprises a shaped panel-like member 10 which preferably tapers slightly from its upper end to its lower end 14 and has a rearwardly-angled upper end region or limb (16, Figs. 1 and 2). The member 10 may be used with or incorporated in a lady's garment (22, Fig. 4) to spread the garment material at the frontal crotch region. This not only improves the appearance of a close-fitting garment but also to minimises any discomfort due to the tendency of a garment to crease and enter the frontal crotch region of the wearer. The member 10 is usually enclosed in a replaceable pad 19, and the member may also be formed with openings 18 for ventilation and, when incorporated in a swimsuit (22), for drainage. In another embodiment (Fig. 5) a replaceable pool (15) has wings (120) for folding over an L-shaped substantially-rigid member (112). <IMAGE>

Title: Device for indicating incorrect insertion of terminals in connector
Inventor: NOLLA MAGRINA FRANCISCO
IPC: H01R13/422
Filed: 1995-11-27
Abstract: A connector 27 is inserted into the device, and teminals 26 with attached conductors or cables 25 are inserted into the connector.

Title: Energy-absorbing shaft structure for a vehicle steering column
Inventor: MORIYAMA SEIICHI
IPC: B62D1/20
Filed: 1996-03-14
Abstract: The shaft structure comprises a shaft 26 which extends completely through a first tube 27a, so that the first tube 27a surrounds a reduced cross-sectional part 39a of the shaft 26, and partly through a second tube 25. The shaft 26 and tubes 25, 27a rotate together. On impact, the shaft 26 moves axially through the tubes and a pressing part 45 of the shaft 26 contacts the adjacent end of shaft 27a to force the tubes together. A position is reached, shown in fig.3, in which the reduced part 39a is aligned with the adjacent ends of the tubes 25, 27a before the other end of shaft 25 reaches the cross-pin 34 of the universal joint. The reduced part 39a thus distorts before the pin is impacted, so responds to a smaller, smoother force and manufacture of the pin 34 is simplified.

Title: Additives and method for controlling clathrate hydrates in fluid systems
Inventor: SLOAN JR EARLE DENDY
IPC: C10L3/00
Filed: 1995-05-10
Abstract: Discussed is a process for preventing clathrate hydrate masses from detrimentally impeding the possible flow of a fluid susceptible to clathrate hydrate formation. The process is particularly useful in the natural gas and petroleum production, transportation and processing industry where gas hydrate formation can cause serious problems. Additives preferably contain one or more five member, six member and/or seven member cyclic chemical groupings. Additives include polymers having lactam rings. Additives can also contain polyelectrolytes that are believed to improve conformance of polymer additives through steric hinderance and/or charge repulsion. Also, polymers having an amide on which a C 1 -C 4 group is attached to the nitrogen and/or the carbonyl carbon of the amide may be used alone, or in combination with ring-containing polymers for enhanced effectiveness. Polymers having at least some repeating units representative of polymerizing at least one of an oxazoline, an N-substituted acrylamide and an N-vinyl alkyl amide are preferred.

Abstract: To make a semiconductor memory device such as a DRAM comprising a substrate 10, a transfer transistor formed on the substrate, and a charge storage capacitor coupled to one of the source/drain regions 16a, 16b, 18a, 18b of the transistor, the capacitor having a charge storage electrode comprising a trunk-like conductive layer 26a,26b of T- or U-section and one or more branch-like conductive layers 40a,40b of inverted L-section, a stack layer 30a,32a,30b,32b, is formed above a conductive layer 26 itself sandwiched between two insulating layers 20,28, the conductive layer extending through a hole 24a,24b in one of the insulating layers to contact the source/drain region of the transfer transistor. Insulating sidewalls 34a,34b are then formed on the stack layer, and a further insulating layer 36 is deposited, after which etching is carried out to form holes which expose portions of the conductive layer 26 adjacent the sides of the stack layer. A further conductive layer is then deposited which covers the remaining areas of the insulating layer 28 and which fills the holes etched therein. The stack layer and the underlying regions of the insulating layer are then removed to form provide a charge storage electrode of the shape shown in Fig 2G. A dielectric layer and further electrode are added to complete the capacitor. In a modification, the upper parts of the branch-like layers 40a,40b extend towards rather than away from each other

Title: Treatment of chocolate
Inventor: SMITH ANTHONY GREGORY
IPC: B05B7/06
Filed: 1997-05-29
Abstract: A method for modifying the flow pattern of a stream of chocolate to assist in the coating, covering or enrobing of food items, comprises an atomisation nozzle in which a liquid stream of chocolate is supplied via the pipe 10 and is discharged through the orifice 12 to flow towards a curved surface 16a. A control fluid which is normally air is supplied through a plurality of nozzles 22 and exits from each of the individual nozzle orifices 24. The control fluid both impinges upon the liquid stream as it passes along the axis A and attaches to the Coanda surface 16a in order to produce the right combination of impingement and shear flow atomisation. Pressurisation of the liquid stream internally aids further with the atomisation, this being achieved by supplying a gas flow through the pipe 18, this gas flow discharging co-axially with the liquid stream at the exit 18a.

Title: Chute
Inventor: HARRISON MARK ANTHONY
IPC: B65G11/18
Filed: 1998-04-15
Abstract: A chute (1) which as an inner sheet or lining (24). The lining is flexible and thereby absorbs some of the impact from items hitting the chute. The sheet may be spaced from the chute, which further aids impact absorbency. The increased impact absorbency of the chute significantly reduces the number of items which bounce completely out of the chute - a significant cost if known manufacturing processes. This chute is particularly suitable for components manufactured using, for injection moulding techniques. A chassis (7) is used to support the chute, and has a base (8) and three adjustable legs (9,10,11 Fig 3), which allow the angle of inclination and the height of the chute to be adjusted. The liner is preferably of plastic such as PVC.
