Title: I.C. engine fuel injection systems using electro fluidic injectors
Inventor: LEIGHTON NIGEL JAMES
IPC: F02M51/08
Filed: 1987-02-04
Abstract: An electronic control unit 13 provides pulsed switching of the fluidic device 1 having the injector nozzle 18 by means of the solenoid valve 12 which opens and closes the port 14. A single two-stage device (1, 21, Fig. 2) may have a nozzle 18 located either upstream or downstream of a throttle valve (30, Fig. 3). For multi-point injection each inlet tract of the engine manifold has an injector nozzle (37, Fig. 4) located near to the associated inlet valve and is supplied by a two-stage device. In order to make the output stage insensitive to sub-atmospheric pressure variations in the manifold one output of the first stage (39, Fig. 5) provides a supply for an ejector (40, 41, 42) which creates a sub-atmospheric pressure in one output 5 of the second-stage 1 to prevent premature switching. <IMAGE>

Patent GB-2216921-A (GB)
Title: Building block
Inventor: ROBERTS PETER
IPC: E04B2/26
Filed: 1989-03-10
Abstract: Building blocks that may provide shuttering for concrete are preferably hollow and have openings (15) so that an assembly can be filled with interconnecting settable material. Blocks engage the blocks above and beneath them to restrain accidental separation. Thus lateral walls (12) may project upwardly and have intermittent outward abutments (58) (separated by gaps), while lower wall portions have complementary inward abutments (60). Thus the two blocks can be brought together (abutments in register with gaps), then longitudinally displaced so that abutments (58) overlie abutments (60). Alternatively ribbed projections 16 on the upper edge of one block may engage ribbed recesses 22 on the underside of an upper block. An assembly of blocks can then be filled, e.g. with concrete or insulating foam, or blocks can be formed about foam cores prior to assembly. <IMAGE>

Title: Sound attenuation duct for a cleaning vehicle
Inventor: BRADLEY RICHARD MAURICE
IPC: E01H1/08
Filed: 1990-06-08
Abstract: A self-propelled cleaning vehicle has suction cleaning gear which deposits matter in a fan-evacuated matter storage tank. The fan (504) is mounted on the top surface of the tank (32). The fan inlet opens into the tank. The pressure side of the fan discharges through a sound attenuation duct (512) of generally U-shaped configuration extending lengthwise of the tank, and disposed generally horizontally, and with an upward discharge opening (520) close to the fan. In this way, a relatively long discharge path is provided with changes of direction of 180 degrees and 90 degrees, whereby significant sound attenuation is achieved without attendant major reductions in fan efficiency. A major portion of the sound attenuation duct is mounted on an openable upper wall of the tank having a rubber seal which damps sound-generating vibration.
