Title: Roll stabilised missile
IPC: G01C19/38
Filed: 1970-12-21
Abstract: 1332911 Missiles MESSERSCHMITTBOLKOW-BLOHM GmbH 21 Dec 1970 [23 Dec 1969] 60666/70 Heading F3A [Also in Division G1] A gyroscopic device 5 in a self-propelled remote controlled missile which is non-stabilized by spoilers, has a rotor 13 gimballed in two frames 11, 12 for movement about three axes 14, 17, 24, a stop 16 limiting the angular movement of frame 11 with respect to the frame 12, so that if the missile climbs at an excessive angle (e.g. above 45 degrees) the frame 12 is engaged by stop 16 and precesses 180 degrees about axis 14, aligned with the longitudinal axis of the missile, thus simulating for the missile an inverted rolling position by operating a changeover switch, comprising semicircular contact paths 22, 23 mounted on the missile housing 15 and a sliding contact 21 fixed to the frame 12, any control signal subsequently received by the missile being thus effectively inverted to ensure that guidance failure does not cause the missile to return to the launch point. Alternatively as in Fig. 3 (not shown) a device (25) may lock the frames 11, 12 to the housing after precession of the frame 12 thus causing the missile to perform a continuous roll to thereby nullify any erroneous guidance signal.

Patent GB-2048519-A (GB)
Title: Control apparatus for air drying equipment
IPC: F26B21/00
Filed: 1980-04-14
Abstract: Control apparatus for air-drying equipment including an electric fan, for example for the drying of agricultural produce, comprises a relative humidity detector 10 for air pumped by the fan when energised by closing of a relay 18. If the detected relative humidity rises above a pre-set maximum allowable level, set on unit 14, the fan is shut down by opening relay 18. The relay 18 is however closed again for 11 DIVIDED 2 minutes every hour, or every 2nd or every 3rd hour, selectable by switch 22, to operate the fan and allow detection of the relative humidity of air pumped thereby. Should the relative humidity then be below the allowable maximum, the relay 18 is latched on, whereas if above the allowable maximum, the fan is shut down again, until the next try after the selected interval. The apparatus also includes three relays 25, 26 and 27 for energising three heater banks, to warm air pumped by the fan. When the apparatus is set to an auto-heat mode on switch 24, heater banks are switched in or out as required to maintain the pumped air at a relative humidity below the set maximum level. In this case the detector apparently measures the humidity of the heated air. <IMAGE>
