Patent GB-2250191-A (GB)
Title: Automatic umbrella
Inventor: LIU FU-TIEN
IPC: A45B25/14
Filed: 1991-05-31
Abstract: A full self-opening and partial self-closing umbrella comprises an upper rib linkage runner 5 and a lower latch runner 13 slidable on a collapsible center-post 2. A cord 12 passes over a pulley 11 fixed to the centerpost's top end, one cord end being connected to the rib linkage runner and the other cord end being connected to the latch runner. In opening the umbrella's center-post and rib linkage self-opens in response to a centerpost spring 10 when the rib linkage runner is released. In closing closure springs 15 collapse the ribs toward the centerpost and the rib linkage runner slides back down the centerpost. The centerpost is then itself collapsed against the bias of the extension spring until the rib linkage and latch runner are latched in position adjacent the handle 1. <IMAGE>

Title: Moulding a module cover for an air bag device which has undercut portions in mounting edge portions thereof
Inventor: ZUSHI TAKAYASU
IPC: B29C45/44
Filed: 1991-10-25
Abstract: A lower mold disposed inside the module cover (1) to be produced is of the split type so that it is composed of a central mold (12) and a plurality of lateral molds (13, 14) for molding of the undercut portions (16). The mating face of the central mold with each lateral mold is oblique so that its bottom is closer to the edge of the module cover than its top. Thus, the module cover produced can be detached from the lower mold by moving the lateral molds mutually inward, in the direction A. The middle mould (12) is preferably integral with a surrounding mould frame (15), and one pair of lateral moulds (13, 14) may define an undercut edge portion along one pair of opposite edges, or two pairs of lateral moulds (23, 24, 25, 26, Figs. 11-15) may define undercut edge portions along two pairs of opposite edges. Inner and outer module cover layers may be injection moulded using replaceable upper moulds (16). <IMAGE>

Title: Child feeding bottle
Inventor: SEPEHR FEREIDOUN
IPC: A61J9/04
Filed: 1991-10-31
Abstract: A child feeding bottle comprises a liquid container (4, fig 3), a teat whereby the child can suck liquid from the container and an one-way air inlet valve 2 operable automatically. The valve comprises a flexible membrane having an opening 3 which admits air into the container when the air pressure within the container becomes depressed relative to the external air pressure, as a result of the feeding action of the child. The valve may be integral with the teat or a separate component removable from teat or bottle. The valve when separate may be removed and replaced to aid cleaning and is constructed in two parts (fig 2). The membrane of the valve is concave and protruding inwardly and is substantially u-shaped in longitudinal section and may be produced in silicone or similar material. <IMAGE>

Title: Extended branch target apparatus for a microprocessor
Inventor: WEISER URI C
IPC: G06F9/38
Filed: 1991-11-20
Abstract: A pipeline instruction processor executes instructions including branch instructions, stored in an instruction memory. The instruction processor includes a branch target buffer which contains target instructions and target addresses corresponding to branch instructions. The target instruction data is indexed according to the address of the instruction which precedes the branch instruction. Also included in the branch target buffer is history data indicating whether the branch was taken. The instruction processor also includes two execution units. The present invention employs logic which allows a branch instruction and its target instruction stored in the branch target buffer to be executed concurrently in the two execution units according to the history data stored in the branch target buffer. Since the branch instructions and their target instructions are executed during the same cycle, branch instructions appear to be executed in zero cycles.   <IMAGE>

Title: Apparatus for folding garments, especially smocks
Inventor: WOLF JURGEN
IPC: D06F89/02
Filed: 1992-10-02
Abstract: An apparatus for folding garments such as smocks has a pro-creasing member 29 for forming a crease along a line prior to folding about that line. The apparatus has longitudinal folding flaps 17, 18 and transverse folding flaps 19, 20 for a successive longitudinal and transverse folding of the garments. Elongated edge portions of the garment are folded in succession over a central portion by the longitudinal folding flaps 17, 18, thus forming an elongated folding tube. This tube puts up resistance to subsequent transverse folding by the transverse folding flaps 19, 20 which can lead to a "jumping up" of the ready-folded garment. To prevent "jumping up", at least one pro-creasing member, which is preferably a pre-creasing strip 29, is assigned to at least one longitudinal folding flap 17 and/or 18, so that the garment is provided with preliminary creases during longitudinal folding. The future transverse folds are thus pro-marked in the folding tube. <IMAGE>

Title: The production of power from a carbonaceous fuel and methanol
Inventor: HORTON ANTHONY
IPC: F02C3/20
Filed: 1993-07-30
Abstract: Carbonaceous fuel is oxidised to form carbon monoxide and hydrogen, which is then catalytically shifted to produce hydrogen and carbon dioxide for combustion in the generation of power. Methanol is cracked using the heat of the shift reaction to produce more hydrogen and carbon monoxide, which optionally may be subject to a shift reaction, to provide additional fuel to meet peaks in the demand for power. The heat evolved by the shift reaction may be transferred to a methanol cracking vessel using a thermal fluid for indirect heat transfer or a methanol cracking vessel may be embedded in the shift catalyst bed. In a further alternative the methanol may be cracked over the shift catalyst bed.
