Title: Lock for a camper,caravan or motor home door
Inventor: CAPPELLARI DINO
IPC: E05C3/24
Filed: 1992-08-04
Abstract: A lock for a camper, caravan or motor home door has a wall-mountable portion attachable to a wall adjacent to a door and comprising a pin (T); and a door-mountable portion attachable to the door and comprising biassing means and first and second pivotable elements (R1, R2), the first element (R1) having a first recess (I3) and a cavity (G) for receiving the pin (T) and the second element (R2) having a projection (D) arranged, upon the pin (T) entering the cavity (G) and pivoting the first element in a forward direction, to enter the first recess (13) under the biassing action of the biassing means to prevent pivoting of the first element (R1) in the reverse direction and release of the pin. The second element (R2) is pivotable to release the projection (D) from the first recess (13) thereby to enable the biassing means to pivot the first element in the reverse direction to release the pin. <IMAGE>

Patent GB-2267410-A (GB)
Title: Variable length coding.
Inventor: JUNG JE-CHANG
IPC: H04N19/196
Filed: 1993-05-28
Abstract: A block of data is runlength coded into a symbol having a variable number of run bits. Initially, the number of run bits is set at the number of bits required to represent the length of the block. However, since the block is of finite size, the maximum potential runlength decreases each time a runlength code is generated. Therefore, the number of bits used for the runlength code is successively reduced as the maximum potential runlength decreases. This coding regime may be used adaptively as an alternative to Huffman coding based on the characteristics of the input data block. <IMAGE>
Patent GB-2282708-A (GB)
Title: Electrical motor-generator
Inventor: ASPDEN HAROLD
IPC: H02K21/20
Filed: 1993-09-30
Abstract: An electrodynamic motor-generator has a salient pole permanent magnet rotor interacting with salient stator poles to form a machine operating on the magnetic reluctance principle. The intrinsic ferromagnetic power of the magnets provides the drive torque by bringing the poles into register whilst current pulses demagnetize the stator poles as the poles separate. In as much as less power is needed for stator demagnetization than is fed into the reluctance drive by the thermodynamic system powering the ferromagnetic state, the machine operates regeneratively by virtue of stator winding interconnection with unequal number of rotor and stator poles. A rotor construction is disclosed (Fig 6, 7). The current pulse may be such as to cause replusion of the rotor poles. <IMAGE>
Patent GB-2272425-A (GB)
Title: Generating slug flow
Inventor: MILLER JOHN STUART SAWYER
IPC: G01F1/74
Filed: 1993-10-28
Abstract: A multi-phase mixture of gas and liquid is passed into a cyclone separator 2 from which separated liquid is passed into a siphon chamber 6 where it enters the inlet to a siphon tube 7 while separated gas is passed into a line 4 and passes via line 10 to the outlet of the siphon tube 7 through a flap valve 11. Any gas from the siphon chamber 6 is also passed to the line 10 via line 8. As the siphon tube 7 fills with liquid separated gas flows via lines 4, 8 and 10 to the outlet of the siphon tube 7 where it can pass through a flow meter 12 such that the flow rate of the gas phase can be measured. When liquid reaches the top of the siphon tube 7 the siphon operates generating a slug or batch of liquid which flows through flow meter 12. The flap valve 11 is closed by the flow of liquid preventing the flow of gas into the outlet of the siphon tube. The gas now passes into the siphon chamber via line 8 such that the vacuum in the siphon chamber is relieved as the siphon operates. When the liquid in the siphon tube 7 is exhausted the siphon action ceases and a mainly gas flow is once again generated through the flow meter 12 as the siphon tube 7 refills. <IMAGE>

Patent GB-2273514-A (GB)
Title: Remote actuation of drill-string equipment
Inventor: AMAUDRIC DU CHAFFAUT BENOIT
IPC: E21B7/08
Filed: 1993-12-06
Abstract: A device for remotely actuating a piece of equipment, e.g. directional drilling equipment, by varying the flow conditions of a fluid in a pipe, has coupling means between the device and the equipment to be actuated and regulating means 2, 3 adapted to vary the geometric characteristics of the passage through which the fluid is channelled as a result of the hydro-dynamic effect of the flow of the liquid in the pipe. An increase in the flow rate through the device when the needle 3 is in choke 2 (Fig 2) causes the equipment (not shown) to be actuated but a corresponding increase in flow rate when the needle 3 is retracted from choke 2 (Fig 2A) does not lead to actuation of the equipment. The needle 3 is retracted by a piston 4 which moves in response to the fluid flow and causes fluid to flow from chamber 9 to chamber 10 via passages 12, 13 and regulator 14 to produce a time delay in the shifting of piston 4. Thus holding the fluid flow rate at a minimum value Qf for sufficient time Tf for piston 4 to retract needle 3 will allow further increases in the flow rate (eg during normal drilling operations) without actuating the equipment, whereas a rapid increase from zero flow rate will not allow time for piston 4 to retract needle 3 and will thus actuate the equipment. <IMAGE>

Title: Standoff compensation for nuclear logging-while-drilling systems
Inventor: SCHULTZ WARD E
IPC: E21B47/12
Filed: 1995-03-29
Abstract: A standoff compensation system for use in a logging-while-drilling system comprises a nuclear count sensor for formation parameters, e.g. density and/or porosity; a standoff distance sensor (48A) and a downhole processor (64) for determining a weighting factor for the density and/or porosity measurements based upon the measured standoff distance. The weighting factor can either be calculated by the downhole processor according to a predetermined weighting function, or can be retrieved from a precalculated look-up table in ROM. The processor then multiplies the weighting factor by the count data from the sensor to determine a weighted count value. The weighted count values are accumulated during an averaging period and normalized, so that a single normalized count value can be generated and either stored in downhole memory, used immediately, or transmitted by telemetry to the surface. Standoff is determined by an ultrasonic transducer whose signals are fed to a spike filter which rejects spurious signals falling outside an acceptable window. <IMAGE>

Patent GB-2301384-A (GB)
Title: Method and apparatus for activation of furnace slag base cement
Inventor: BROOKS FRED
IPC: C04B40/00
Filed: 1995-01-25
Abstract: The invention provides for metering the pumping rate of BFS/mud mixtures pumped to the cementing head on a rig for sealing off the formation from the casing. Since BFS/mud mixtures require an activation agent, preferably sodium hydroxide is pumped into the flowline to the cementing head. Feedback from the BFS/mud slurry flowrate is fed to the activator injector pump drive system to regulate the addition rate of the activating agent in response to varying conditions, such as mud flowrate. The injection rate target can also be adjusted to compensate for any changes in downhole temperature. The risk of fouling surface equipement and the casing internal diameter is minimized because the activation agent is added very close in time to when the BFS/mud mixture enters the cementing head. Even in situations where the anticipated downhole temperature is significantly lower than the surface temperature, a sufficient amount of activating agent is added for the downhole conditions without fear of fouling the casing internal or the surface pumping equipment.

Title: Printed circuit board for flow soldering
Inventor: FURUTATSU TETSUYA
IPC: H05K3/28
Filed: 1996-09-06
Abstract: The printed circuit board comprises an electrically conductive pattern having a plurality of connection pads 7 to which leads 3a of electronic components are to be connected; and a solder resist layer 6 formed over said electrically conductive pattern with a plurality of windows 2 which expose said connection pads. At least one of said windows has an extension 2a exposing an additional part of said pad, said extension being substantially narrower than said window. The extension allows the additionally exposed part of the pad to contact with the solder even when the associated pad is almost entirely covered by trapped gas, so that the solder is pulled to the pad and spread over the pad. Because the extension require a small area, it is effective even when the components are mounted at a high density.
