Title: Circuit for operating vehicle warning lamps
IPC: B60Q11/00
Filed: 1979-05-18
Abstract: An auxiliary road-vehicle lighting circuit, for providing enhanced lighting display in hazardous situations, has a flasher device (5), auxiliary hazard lamps (23, 24), and brake stop lamps (18, 19). When a first switch (1) is set to its first position (4) a train of energising pulses is fed to the foot brake lamps (18, 19). These therefore flash in unison, provided they are not coupled directly to the battery via the normal brake operated switch (17). When the brake is operated, the stop lamps give steady illumination. In the second position (6) of the first switch the flasher device (5) is de-energised and the auxiliary lamps (23, 24) are coupled to the battery via normally open contacts (7) of a relay (8). Hence the auxiliary lamps provide steady illumination when the brake lamps come on with operation of the brake operated switch (17). A second switch (21) provides in one position (22) steady illumination of the auxiliary lamps (23, 24) and in its second position (27) flashing operation thereof. Suitable warning lamps (14), (25) for display to the vehicle driver are connected into the circuit. <IMAGE>

Title: Method of air conditioning
IPC: B01D53/26
Filed: 1979-11-22
Abstract: An air conditioning method wherein supply air is introduced into an air conditioned space to maintain a condition of temperature and humidity of air within that space. The invention is characterised in that the air is passed over the cold coil of a dehumidifier both with a low face velocity and a low Reynolds number, resulting in the coil condition curve being compatible with the load ratio line and in turn achieving an energy saving. This invention relates to a method of air conditioning and has as its main object the conservation of energy as well as the improvement of air conditioning system performance. The low face velocity is between 0.4 and 2 metres per second. The meaning of "Reynolds number" is defined in the Specification and a numerical range for it is specified. In almost all instances, the need to reheat air which has passed over the dehumidifier is avoided.
