Patent GB-2118643-A (GB)
Title: Hydrodynamic transmission device
Inventor: BIONAZ JEAN
IPC: F16H45/00
Filed: 1983-04-19
Abstract: A hydraulic coupling or torque converter (10) includes a double- acting clutch piston (3c) selectively engageable with a loose turbine (25), for transmitting drive from the turbine via damper (46) to output shaft (33), or with casing (31) for providing direct drive. With manual selector valve (75) in the neutral position shown, working fluid is directed to both sides of the piston to centralise it, and with valve (75) in its alternative setting fluid is directed to chamber (61) to engage the piston with the turbine. Direct drive is obtained under the control of a second valve (89). This arrangement facilitates gear changes in a semi-automatic transmission driven by the output shaft. <IMAGE>

Title: Improving the angular resolution of monopulse radars
Inventor: DORIATH GEORGES
IPC: G01S7/41
Filed: 1983-11-29
Abstract: An anti-glint system does not require resolution of the Doppler spectrum of a target. Starting from sum signals S, direction signals θb, and signals representing the imaginary part |εq| of the angular deflection measurement, the method consists of calculating 201, first of all, a signal representing the wingspan of the target. Two measuring signals θA, θBrepresenting the external limits of the target, as well as a signal Q representing the quality of these measurements are derived in step 202. Finally, an adaptive filtering operation 203 on the measurements gives filtered estimates.

Patent GB-2142342-A (GB)
Title: Improvements in and relating to combustion
Inventor: HARDY LEONARD RHYS
IPC: C10L10/00
Filed: 1984-06-22
Abstract: During operation of a fossil fuel boiler the combustion process results in the deposition in the boiler flues and heat transfer pipes of scale, smut and soot and other solid products which have a serious effect on boiler efficiency. Regular cleaning therefore has to be undertaken in order to maintain a reasonable standard of boiler efficiency and this is both expensive and time consuming. The present invention introduces controlled amounts of ferric oxide (Fe2 O3) the effect of which is to inhibit the deposition of further solid combustion products such as scale, soot and smut and also to alter the character of existing scale, reducing its adhesion and causing the scale to fall away. The effect is to improve boiler efficiency and reduce maintenance costs.
