Title: Implements with handles
Inventor: BRUCE ANDREW GORDON CAMERON
IPC: B62B5/06
Filed: 1990-07-30
Abstract: An implement, such as a two-bladed kayak paddle, includes an operating handle 10 having handgrips 14, 15 which, in use, are hold by the two hands respectively of the user. To facilitate manipulation of the implement, the two handgrips are asymmetrically inclined with respect to a common axis passing through the two handgrips, for example they are offset by 11 DEG  as viewed along said axis. In other cases, for example where the implement is a wheelbarrow, bicycle, stretcher or walking frame, the two handgrips are asymmetrically inclined with respect to two parallel axes passing through the handgrips respectively. In this case one handgrip may be inclined upwardly at 11 DEG , and the other inclined downwardly at 11 DEG  to the plane containing the parallel axes. Alternatively, the implement may have a shaft and a handgrip for rotating the shaft, e.g. a screwdriver, hydrant key or single-bladed paddle. <IMAGE>

Title: Transaction processing.
Inventor: HASLAM PATRICK BERNARD
IPC: G06F11/14
Filed: 1992-04-10
Abstract: A transaction processing apparatus carries out real-time transaction processing on receipt of both local data and remote data. The effect of data errors arising due to either hardware faults or human error, are virtually eliminated by operation of a re-build processor (10) which continuously monitors operation of the real-time processor (6). Accordingly, data structures may be rebuilt very quickly after a fault arises. In addition, an offline processor (8) operates in parallel with the real-time processor (6) and uses data in its associated database (9) to compare and verify processed locally received data and remotely received data. The offline processor (8) does not operate in real-time but in point-in-time at regular intervals to allow correction of errors and updating of data which is to be verified. <IMAGE>

Patent GB-2270724-A (GB)
Title: Machine tools
Inventor: CHILD ROBIN EDWARD
IPC: F16J15/16
Filed: 1992-09-19
Abstract: The bearing of a machine tool spindle is sealed by a pair of wiping seals mounted on the shaft and resiliently urged into contact with opposite faces of a stationary ring through which the shaft extends. The very small clearance between the ring and the shaft is fed with gas for example air at low pressure. When there is no gas supply and for example when the shaft is stationary the seals contact the ring and the resilience ensures good contact and prevents seepage of for example lubricant along the shaft from one side of the seals to the other. When the shaft is to be driven, low pressure gas is supplied and this pressure deflects the seals to lift them from the face of the ring so that there is no frictional engagement and either power loss or heat generation, and any liquid which does go past the seals is thrown outwardly by centrifugal force and driven by the escaping gas.

Title: Detection of data bits in a slow frequency hopping communication system
Inventor: MEDIAN REUVEN
IPC: H04B1/713
Filed: 1992-10-22
Abstract: In the detecting process, the carrier to interference (C/I) power ratio of the hop of a slow frequency hopping spread spectrum signal (112), is estimated (124) by using the data samples (120) of the hop. Subsequently, a data bit (130) is detected by using the estimated C/I power ratio (126). The detection process (128) may include utilizing maximum likelihood decoding techniques to derive a data bit (130) from decision metrics and the estimated C/I power ratio (126). The decision metrics correspond to a measurement of the distance of data samples (120) from constellation points within a constellation space representing data samples (120) previously used to generate decision metrics. The detection process (128) also may include utilizing the estimated C/I power ratio (126) in combining data samples (120) of the hop as received from two or more diversity receiver branches. <IMAGE>

Title: Self-cleaning nozzle having pin actuated by fluid flow
Inventor: CHICKEN ROBERT RICHARD
IPC: B05B15/02
Filed: 1994-06-15
Abstract: A pin which moves in and out of the aperture of a nozzle has its movement controlled by means of the fluid pressure. A typical example is a self cleaning screen washer for vehicles to prevent the ingress of dirt into the nozzle, comprising a body 1, a nozzle 2 and pin 3 which normally rests within the nozzle cavity. When water is pumped from the reservoir via tube 8, the pressure forces the piston 4 down the sleeve 9, drawing the pin out of the nozzle cavity, and allowing water to flow out of the nozzle, and on to the screen. When the water ceases to flow, the spring 6 forces the piston to return to its original position, and the pin to return to its rest position within the nozzle aperture. In this position, the pin prevents any ingress of dirt into the nozzle. A second example is where the fluid is held in a pressurised container 12, such as spray on adhesives used in the advertising industry, and has the discharge of fluid controlled by a valve 13. A third example is where the fluid is pumped from a reservoir using a manually operated pump 19 such as insecticide sprays. <IMAGE>

Title: Multiphase fluid flow measurement
Inventor: FORDHAM EDMUND JOHN
IPC: G01N21/43
Filed: 1995-07-31
Abstract: An optical fibre probe for measuring the flow rates of different components of a multiphase fluid from an oil well comprises a doubly-angled tip, there being measured the light totally internally reflected at the interface (37), which depends on the ratio of the refractive indices of the probe tip and fluid component in which it is immersed. The invention also proposes an improved method using such a tipped probe, in which, to facilitate distinguishing between the components of a multi-phase fluid such as the gas/water/oil formation fluid in an oilwell, there is employed a pair of adjacent probes, one of which is designed to distinguish between gas and liquid and the other of which is designed to distinguish between oil and "not oil" (gas/water), and there are then logically combined the outputs of the two so as to give an indication of which component the probes are in. The probe tip has a first surface 37 interfaced with the fluid and a secondary surface 38 which may carry a reflective coating 34, or may also interface with the fluid, the angles  alpha ,  beta  being such that light is reflected back up the fibre under conditions of total internal reflection. <IMAGE>
