Title: Mobile radio dynamic channel allocation
Inventor: TAKAHASHI HIDEAKI
IPC: H04W72/10
Filed: 1996-09-13
Abstract: Channel allocation is effected depending on radio channel priority degrees P which are initialized to values in a memory (step 1001). A priority degree modification frequency count value x is initialized to zero (1002). When a communication request is present (1003), the channel with the highest priority is selected for consideration (1004). If that channel is idle it is allocated (1007), but if it is not idle the next highest priority channel is considered. The priority degree P of a selected channel is increased or decreased according to whether the channel is idle or not idle respectively (1006, 1008), the amount of increase or decrease * capital Greek delta *P(x) being a function of the value x in the modification frequency counter, the amount increasing as x decreases (Fig.5). When a channel has been allocated, or when all channels have been considered, the counter is incremented (1012) and it is determined (1013) if count value x has exceeded an upper limit x 0. In the prior art (Fig.4), the counter was reset to zero when the limit value was exceeded, resulting in loss of past history of channel priority degrees. In the present invention, further communication requests are processed without resetting the counter to zero. When the upper limit is exceeded, the counter may be reset to a value x 1 intermediate zero and limit x 0. Alternatively, (Figs.9-11), a master channel allocation procedure may first be followed similar to the above steps until an upper limit for the master priority degree modification frequency has been exceeded. A slave channel allocation procedure is then followed which is similar to the master procedure but operates with slave priority degrees P' (initially set at the master values) and with a slave modification frequency counter value y . When the slave count value exceeds an upper limit, a test is made to determine if the system is stable. If stable, the slave procedure is continued after reset of count y to zero, whereas instability results in reversion to the master procedure. The system is considered stable if the slave priority degree P' is approximately equal to the master priority degree P.

Title: Drilling structure with enhanced hydraulic flow characteristics
Inventor: TRUJILLO WILLIAM R
IPC: E21B10/38
Filed: 1997-04-03
Abstract: This invention discloses a drilling structure having body defining at least one primary channel 30 and at least one secondary channel 32 therein to initiate and maintain recirculation of an amount of drilling fluid back through the secondary channel 32 to maintain positive, independent flow of drilling fluid through each primary channel of the drilling structure. The recirculation of drilling fluid is encouraged by providing a recirculation passageway 32 in fluid communication with the primary channel 30 defined by a portion 34 of the body of the drilling structure that separates positively flowing drilling mud from drilling mud that is being recirculated. The recirculation action of the fluid in the recirculating loop may be fed and brought about by entrainment of the fluid with jetted fluid from an adjacent nozzle. The portion of the body may form a partition 34, such as a wall extending at least partially between the sides of the primary channel, a fin positioned within the primary channel that generally radially extends from the centre line of the drilling structure, or an internal channel or feeder that extracts fluid from the annulus at a point of low velocity and reintroduces it at a point of higher velocity proximate the bit face, usually near a nozzle. In addition, portions of the drilling structure are streamlined to further encourage positive, stable flow of fluid and formation cuttings generated from an associated cutting structure.

Title: A composite filter screen
Inventor: MORRIS RONALD GEORGE
IPC: B01D39/20
Filed: 1997-05-06
Abstract: A composite filter screen suitable for use in a vibratory screening apparatus comprises first fine mesh (screening) layer 1 laminated to second coarse mesh (backing) layer 2 so that the first mesh layer is held in a state of tension by the inherent rigidity of the second mesh layer. The screen is prepared by applying heated platen 5 to first mesh layer 1, which is held in tension in the directions indicated by the arrows in Fig. 2, second mesh layer 2 and plastic layer 3 which are stacked upon each other on metal surface 4. This pressure is applied to the stack for a fixed period of time and then platen 5 is raised. This causes plastic layer 3 to melt and flow into mesh layers 1 and 2. Thus, upon cooling, mesh layer 1 will bonded to mesh layer 2 with the required degree of tension. A composite filter screen (6) prepared using this method can be incorporated into a vibratory screening apparatus using the constructions of Figs 3 and 4 (not shown). The mesh layers are preferably formed from woven wires, particularly metal wires such as stainless steel and they may be coated in plastic.

Title: Vehicle drive force controller
Inventor: TOUKURA NOBUSUKE
IPC: B60W30/18
Filed: 1997-11-19
Abstract: A vehicle drive force controller comprises a navigation device for determining whether or not the vehicle is travelling in a mountainous region. The navigation device comprises a global positioning system for determining vehicle position, combined with a memory in which is stored altitude data for an area surrounding the vehicle position. A microprocessor determines the slope of the road on which the vehicle is travelling from the altitude data, and then a vehicle drive force characteristic suitable for a mountainous region is selected if the slope is equal to or greater than a predetermined value. A different drive force characteristic is selected if the slope is less than a predetermined value. The drive force characteristic may be the throttle gain of an electronic throttle or the speed change pattern of an automatic transmission. The microprocessor can be programmed so that the throttle opening is larger when the vehicle is travelling in a mountainous region, or so that a lower gear is selected when the vehicle is in a mountainous region.
