Patent GB-2283736-A (GB)
Title: Valved closure for venting container
Inventor: BOUHANNA CLAUDE
IPC: B65D51/16
Filed: 1994-11-10
Abstract: A closure for sealing a vessel having a neck 5 comprises a closure cap with an aperture 22 and a flexible disc shaped valve member 25 secured to the cap. The member 25 tightly seals against the neck in a closed position of the cap (figure 2) and at least a portion of the member can be displaced inwardly when the cap is in a partially opened position to allow inflow of air to the vessel interior if negative pressure occurs within the vessel. If on the other hand excess pressure occurs within the vessel, then in the partially open position of the cap venting can occur, e.g. by means of a passage 20 between the screw threads of the cap and neck or through an uncovered side opening 90 in the cap. The member 25 may include a flap (95, figure 8), in which case only the flap 95 is displaced to allow inflow of air. The cap may connect with the vessel by means of screw threads or a bayonet connection or a two-position connecting means. The vessel may contain dangerous liquids such as acids. <IMAGE>

IPC: B01F5/02
Filed: 1995-07-31
Abstract: In a crossflow gas-liquid contact tower, liquid moves horizontally across a plurality of vertically spaced trays, and downwardly from tray-to-tray while gas flows up through openings (16) in the trays to create a liquid-vapor mixture in an active bubble area. Each tray is formed of panels (7, 9) with mutually overlapping margin portions (7M, 9M). Overlapping vapor openings (16M, 17M) are formed in the overlapping margin portions (7M, 9M) in order to provide the tray with a greater open area and with a more uniform aperture distribution. Preferably, each opening includes an aperture (16, 16M) in the plane of the tray, and a deflector (18) overlies the aperture to define lateral vapor outlet slots. The aperture is wider at its upstream end than at its downstream end; and, the deflector (18) has upstream and downstream portions (18u, 18d) which extend across the ends of the aperture. <IMAGE>

Title: Limited run branch prediction
Inventor: ISAMAN DAVID L
IPC: G06F9/38
Filed: 1995-11-20
Abstract: A branch prediction technique which increase the likelihood of correctly predicting the direction of a conditional branch instruction is presented. The technique is based on the observation that many branches have run lengths that are constant or slowly-varying, i.e. several consecutive runs of 1's are of the same length. The technique uses the history stored for each branch, which history is enhanced by two small counters (102, 113), an up counter (102) and a down counter (113). These counters (102, 113) operate in conjunction with a state machine branch predictor (101) of the prior art for very accurate predictions.
