Title: Plug-in air hybrid vehicle
Inventor: MA THOMAS TSOI HEI
IPC: B60K6/12
Filed: 2008-02-27
Abstract: An air hybrid vehicle is powered by a downsized internal combustion engine (16 see fig 1) equipped with a rotary air charger (10 see fig 1) which may be a supercharger and/or a turbocharger for pressure charging the engine while having selectable means for loading and unloading the air charger. At times when there is access to a high pressure compressed air source (100 see fig 1), the compressed air source is connected to an air accumulator (110 see fig 1) in the vehicle for delivering into the accumulator a charge of high pressure compressed air which is stored in the air accumulator, and at times when there is no access to a high pressure compressed air source and the vehicle is driven on load by the engine (16) the air supply to the engine (16) is selectable by one of at least three routes: a) naturally aspirated when boost is not required and the rotary air charger (10) is unloaded, b) pressurised air is delivered from the air accumulator (110) to the engine (16) when boost is required while the rotary air charger is unloaded, and c) pressurised air is delivered from the rotary air charger(10) to the engine (16) when boost is required and the rotary air charger is loaded. The vehicle achieves fuel saving and high performance by not having to drive the rotary air charger when the engine (16) is supplied with pressurised air according to route b) pre-charged in the air accumulator (110). Mains electricity is used to power the high pressure compressed air source (100) so that the vehicle benefits from energy displacement by indirectly using mains electricity instead of on-board fuel to power the boosting of the engine (16).

Title: Device, system and method of point to multipoint communication
Inventor: OVADIA YAKIR
IPC: H04W28/16
Filed: 2008-05-23
Abstract: In some wireless communication systems, for example, Code Division Multiple Access (CDMA) systems and Wideband CDMA (WCDMA) systems, multiple wireless communication stations may share an access medium. For example, time and/or frequency resources may be shared among multiple devices, e.g., utilizing Orthogonal Frequency-Division Multiplexing (OFDM). A central point of the wireless communication system, for example, an access point or a servicing station associated with multiple mobile stations, may allocate communication channel resources to the mobile stations, e.g., by transmitting control information. Unfortunately, overhead may be incurred due to exchanging and/or handling of control information.

Title: Tidal power device uses long pipeline to accelerate water and air flow
Inventor: NEWTON ALAN
IPC: F03B13/26
Filed: 2009-06-03
Abstract: A tidal power system consists of a long pipeline 1 made up of a series of pipes (2, figure 2) arranged parallel to the tide line and shore line and connected at their ends with 180 degree bends (3, figure 2). The pipeline 1 extends from low tide to high tide positions, so that the water fills and empties the pipe as the tide changes. An airflow is therefore produced which powers a multi blade wind turbine 9, and the water flow drives turbine 10. The pipeline is connected to the air turbine 9 via a diffuser 7 which may draw in additional air (see figure 6). The increased length of the pipeline 1 increases air and water velocity compared with a similar pipe which runs straight between low and high tide positions.

[Class 94 (i)] [See also Group VI] In an arrangement for spreading the tobacco showered to a moving tobacco - receiving surface 3, in a tobacco - packing or cigarette - making machine, the shower is subdivided into widths extending lengthwise of the moving surface and the tobacco of each subdivision is given a horizontal movement or a horizontal component of movement and also a lateral movement transverse to the direction of movement of the moving surface. The position at which the horizontal movement is given to the tobacco is at a sufficient height above the moving surface to spread the tobacco of each subdivision lengthwise of the surface to a width 7, greater than the original width 8 of the subdivision so that, due to the lateral movement, the heavier tobacco particles 10 of one subdivision are mixed with the lighter particles 9 of the adjacent subdivision as indicated in plan in Fig. 4. In the arrangement shown, tobacco is showered from a distributer roller 1 by a picker roller 2 on to a moving surface 3, which may be an endless moving band or a web of cigarette paper to be formed into a continuous rod. The shower is subdivided by inclined plates or vanes 5, the lower ends of which are bent forwardly to give the subdivided portions of tobacco a horizontal component of movement and are also set askew to the direction of movement of the surface 3 as indicated in Fig. 3. The plates or vanes 5 may be of semicircular or trough-like section. The surface 3 may move in a direction opposite to that indicated by the arrow B, Fig. 1, so that the tobacco is given a component of movement in a direction opposite to the direction of movement of the surface 3.
