Title: Non-return device
Inventor: O'HARA JUDITH
IPC: E03C1/298
Filed: 1994-12-22
Abstract: A non-return device 1 comprises flexible, impervious wall members 7, 9 of complementary shapes disposed face to face in surface contact so that there is no through passage between them in their normal state and resiliently urged into the said normal state, and means 13 holding the said walls spaced from one another at an end of the device to define an inlet 11 for ingress of fluid to the interface of the said members 7, 9, whereby inflowing fluid will force the said members 7, 9 apart to permit flow between them from the inlet 11 and to the other end of the device 1. Flow in the opposite direction is prevented by the close surface contact between the members. Thus, in their normal state, the mutually contacting wall members 7, 9 prevent flow between them towards the inlet, but fluids entering the inlet can force the wall members apart and flow between them. The device can form an odour trap for domestic plumbing. <IMAGE>

Title: Multi-line game machine
Inventor: KOJIMA KOUYA
IPC: A63F7/02
Filed: 1997-08-07
Abstract: A gaming machine has a display on which an array of patterns a-i may be displayed. Paylines are defined to include series of displays that form not only straight lines 2 such as the rows or columns and diagonals but also combinations of displays including one display from each column that do not define a straight line 1. This definition of paylines allows a potentially winning payline to be generated incremental as a pattern is generated on each additional display one-by-one as the game progresses. Thus, a first payline, for example the centre row, can be generated. Next, a bet can be accepted and a pattern generated on a single additional display. The new display will form at least one new payline. Adding another display will form even more paylines so that the number of paylines added with each additional display increases as the number of bets are made.
Patent GB-2330390-A (GB)
Title: Blind rivet
Inventor: DENHAM KEITH
IPC: B21J15/04
Filed: 1997-10-10
Abstract: A blind rivet comprises a tubular shell 11 and an inner concentric stem 12, which has an enlarged head 13 protruding out of the shell 11 on the blind side of the rivet. When tension (F1, Fig 1B) is applied to the stem 12 on the open side of the rivet, a nosepiece 24 of the tool takes up the reaction force (F2) against the end face 23 of the shell 11, and a portion 20 of the shell 11 deforms outwardly to form a bulb (31) between a groove 19 in the shell 11 and the head 13. This eventually forms a blind head (32, Fig 1C) or folded flange. On continued application of the tension (F1), the sheets 26,27 being joined are pulled together, and the open side head is either provided by forming another folded flange (37, Fig 2D), or rolling the upper part of the shell 11 outwards to form a head (58, Fig 4C).
