Title: Electric switches
Inventor: PICKERING IAN JACK
IPC: H01H23/02
Filed: 1983-07-18
Abstract: An electric switch comprises a face plate (6), a rocker assembly (8), and a contact assembly (10) with a contact (38) movable between open and closed conditions in relation to fixed contacts (12, 14) and which is adapted to be so moved by means of the rocker assembly (8). The movable contact (38) is adapted for snap-fitting engagement with a fixed contact (36), the fixed contact being provided with resilient formations which may temporarily be deformed to enable the movable contact to be snap-fitted into engagement with the fixed contact. The movable contact is moved by the rocker assembly through the intermediary of a spring-loaded plunger (22) which is constructed and arranged so as to be in contact with the movable contact member along a line which extends at right angles to the direction of relative movement between the plunger and the contact assembly. <IMAGE>

Title: Monitoring the speed of a member using Hall effect devices
Inventor: MERZ STEVEN GUSTAV
IPC: G01P3/49
Filed: 1984-04-06
Abstract: The speed of movement of a member which makes a to-and-fro movement is monitored. A magnet 14 and a Hall sensor 16 are mounted so that magnetic flux created by the magnet 14 passes in succession through a detection zone 18 and the Hall sensor 16. A vane 26 of electrically-conducting but non-ferromagnetic material is mounted on the operating member so that a constant amount of the vane projects into the detection zone throughout the movement. The output of the Hall sensor depends upon the speed of movement since the magnetic field through the Hall sensor is reduced by eddy currents in the vane. In Fig. 1 the movement is rotary, but linear speeds can be measured in a similar manner using a rectangular vane, Fig. 2 (not shown). <IMAGE>

Title: Ventilating cabinets for electronic components
Inventor: MARTIN SIDNEY HAROLD
IPC: H05K7/20
Filed: 1986-04-07
Abstract: Electronic components 18 housed in a cabinet are cooled by directing an airflow over the components. The distribution and the direction of the airflow is controlled by deflector vanes 21 extending at an angle to the incident air flow induced by a fan 14. Undesirable turbulence resulting in uneven and decreased cooling effect is reduced by providing apertures 24 in the vanes which are effective to reduce the pressure differential between opposite sides of the vanes. <IMAGE>
Patent GB-2439987-A (GB)
Title: Angle tracking radar system
Inventor: PAWSEY PETER GRAHAM
IPC: G01S7/295
Filed: 1986-05-12
Abstract: An angle tracking radar system for a guided missile employing a 'strapdown' antenna, i.e. one that is physically locked to the missile body. Accurate guidance of the missile is dependent upon an accurate determination of the sightline and/or sightline rate. This in turn is dependent upon an accurate knowledge of the relation between the target angle and the receiver output signals. The antenna characteristic is derived as a simple function of the direction cosines of the line of sight and constants of the antenna and estimates of these quantities are obtained in a Kalman filter providing sightline and sightline rate estimates.

Patent GB-2189031-A (GB)
Title: Vibration sensor unit for alarm system
Inventor: WILD GRAHAM
IPC: G08B13/16
Filed: 1987-04-01
Abstract: A vibration sensor unit for an alarm system has a vibration transducer, such as a piezo-electric crystal (4), connected to a circuit 5 which includes a sensitivity control (21) and to a switching circuit 8 having an indicator LED (9). The unit can be used in a set-up mode in which the indicator LED (9) is switched on when the transducer (4) is vibrated and is switched off after the vibrations terminate (rather than latching, as in the case in a normal operational mode of the unit). A delay is introduced before the lamp switches off so that it is readily noticeable. The delay is produced with a capacitor circuit (22). The vibration sensor may be replaced by an acoustic sensor and the arrangement may include an IR detector. An anti-tamper switch 16 is also included. <IMAGE>
Patent GB-2190807-A (GB)
Title: Method of ventilation or heat transfer
Inventor: THIEMANN HANS-JOACHIM
IPC: H02P7/288
Filed: 1987-04-08
Abstract: In a method of ventilation or heat transfer employing a fan, the speed of rotation of the fan motor (M) is controlled by a timing-pulse generator (T) with variable timing-pulse frequency and/or pulse width. In order to protect the fan motor and the timing-pulse generator in a simple and inexpensive manner from damage in the event of blockage of the fan, the counter e.m.f. produced by the fan motor is measured in the intervals between timing pulses and the timing-pulse generator is switched off if the counter e.m.f. drops below a preset limiting value. The limiting value may be dependent on the timing pulse mark-space ratio. The system may be used for temperature regulation in a vehicle, using a temperature sensor (F). <IMAGE>
