Patent GB-2037544-A (GB)
Title: Well Logging System and Method
IPC: G01V11/00
Filed: 1979-10-05
Abstract: The invention provides for the display on a cathode ray tube of well logging data. The logging measurements are preferably derived in or converted to digital form, and are thereafter applied to video circuits for graphic display as the measurements are derived in the borehole. The image is continually scrolled in correlation with movement of the sonde through the borehole whereby a visible representation of a preselected portion of the measurement may be continuously observed as it is obtained. In particular, graphic information relating e.g. to a grid of horizontal (depth) and vertical (calibration) lines are stored in memories 24, 25 and logging information in memory 26. Data is read into and out of the memories by a video controller 34 which causes the lines and measurements to be displayed on VDU 16 by controlling beam deflection through counters 22, 23 and bright-up through switch 17. The data signals and the depth (horizontal) lines are scrolled in unison. Thus, on receipt of a new data signal, the controller 34 increments the value held in Y-register 32 through a line-scroll generator 33 (Fig. 4) and updates the address to the log memory 26 through address generator 28 (Fig. 3). <IMAGE>

Title: Variable area thrust nozzle
Inventor: TAYLOR MAURICE IAN
IPC: B64C29/00
Filed: 1979-11-28
Abstract: Elbow nozzles in VTOL aircraft engines are highly stressed when operating, in that they act, as high pressure vessels, and the invention provides a means for varying the outlet area of such a nozzle (24) without weakening its structure. A single flap (34) is inserted inside the nozzle (24) and connected to the nozzle extremity for pivoting about an axis (36) which lies across the outlet (32) between a position wherein its edge periphery (38) seals against the nozzle side and so restricts the nozzle outlet to an area (40) and, a position wherein it lies parallel with a wall of the nozzle (24) so that exhaust gas can pass both sides and out of the larger outlet area (42). Such single flap means can also be utilised in straight nozzles, as in the gas generator outlet nozzle (52, Figure 1, not shown).

Title: Pistons and reinforcements for piston ring grooves
IPC: F16J9/22
Filed: 1980-07-17
Abstract: A piston having a piston ring groove (1) which is bounded on at least one side by a reinforcing element (3). The reinforcing element (3) is provided with at least one recess into which material of the piston extends to establish a bond between the reinforcing element and the piston.

Patent GB-2073533-A (GB)
Title: Vehicle-mounted radar apparatus
IPC: G01S13/931
Filed: 1981-03-31
Abstract: Radar apparatus is mounted in a vehicle so as to transmit a radar signal in a rearward direction with respect to the direction of travel of the vehicle. The signal is reflected from objects behind the vehicle, and a detection is given when the relative speed between vehicle and object is a closing speed, in other words a detection is provided when a following vehicle is closing the distance between it and the radar-equipped vehicle. When the closing speed exceeds a threshold value, an alarm device, such as a rearwardly aimed flashing light, is activated thereby warning the driver of the following vehicle; as an alternative or an addition, a suitably equipped following vehicle might have its automatic braking system activated. Doppler radar apparatus provides a particularly simple implementation, since differences in the frequency characteristics of the received signal when compared with the transmitted signal can be readily used to detect whether any relative speed is a closing speed or not, thereby avoiding detection of receding background objects. <IMAGE>

The alkyl chloroformate is introduced either simultaneously or prior to the base such that the pH of the reaction mixture does not exceed 8. Finally the substituted urea is subjected to ring closure by adjusting the pH of the mixture between 9 and 10.5. The intermediates need not be isolated.
