Title: Improved process and apparatus for the dynamic compacting of earth
Inventor: COGNON JEAN-MARIE
IPC: E02D3/046
Filed: 1983-06-06
Abstract: According to the invention, compacting is improved by the fact that the energy of compacting is delivered in the form of successions of double shocks separated by a very short interval of time. Two masses (M1, M2) suspended one below the other and separated by a small distance d which is adjustable for regulating the interval of time separating the two shocks are advantageously used for this purpose. The invention is applicable to the treatment of any type of ground to be compacted. <IMAGE>

Title: Air swirl systems for fans
Inventor: PAK VITOLD VITOLDOVICH
IPC: F04D29/46
Filed: 1984-10-22

Title: Hand power disc sander dust extracter
Inventor: BRADSHAW COLIN JOHN KENELM
IPC: B24B55/10
Filed: 1985-04-09
Abstract: A hand power disc sander is fitted with a dust-proof hood in the form of flexible bellows (F) and evacuated by an extractor fan (e.g. a vacuum cleaner via a flexible hose). Grooves (H) in the hood rim (G) permit inflow of air over the work surface. The flexible bellows (F) permit engagement and tilting of the sander disc without disturbing the position of the rim of the hood. The rim is held against the work surface principally by the suction of the extractor fan. The bellows are so constructed as to resist lateral movement of the rim to prevent fouling the sanding disc. A variable air-bleed (R) is incorporated in the combined outlet pipe and supplementary handle (E) to compensate for the varying power of different vacuum cleaners. The invention may also be applied to a disc sander in which a single motor drives both the sanding disc and the extractor fan. <IMAGE>

Patent GB-2161626-A (GB)
Title: Engine control system including idle speed control
Inventor: DEUTSCH ROBERT W
IPC: F02D31/00
Filed: 1985-07-04
Abstract: The system includes closed loop control of idling speed when it is enabled by the simultaneous occurrence of the speed error being within a predetermined range about zero, the actual speed being less than a predetermined speed, and the throttle closed. While it is enabled the speed is adjusted by an air bypass in response to the speed error plus the integral of the error. Also while idling the manifold air pressure (related to fuel consumption or torque) is averaged for comparison with this value at other times to produce a "torque polarity signal", i.e. whether or not the engine is being overrun during deceleration. If it is the air and/or fuel supply are adjusted. At all times the fuel supply is controlled in response to the manifold air pressure. The desired idling speed for the closed loop is a function of coolant temperature. Also disclosed is a feature whereby the integral of the speed error when last idling is stored during non-idling for immediate use when idling is resumed.

Date Mar. 22, 1990.A displacement measurement apparatus includes a primary electrode, and first and second secondary electrodes which are closely spaced apart and together fully span the primary electrode, the primary and secondary electrodes being movable relative to one another without increasing their transverse separation. A charge pumping means is arranged to supply electric charge to the primary electrode through the first secondary electrode during selected first clock periods, and to withdraw charge from the primary electrode through the second secondary electrode during selected second clock periods. The changeover from one mode of operation to the other is made automatically when the sign of the charge on the primary electrode reverses, so that the charge on the primary electrode is successively increased, and then reduced to a low value. The numbers N1 and N2 of charge packets supplied to and withdrawn from the primary electrode during a measurement cycle are counted, and a displacement signal is produced in accordance with the relationship (N1-N2)/N1. The electrical system may also be used for determining in a similar manner the ratio of the capacitances of any two capacitors.
