Title: F.M. demodulator
Inventor: BADGE ROGER
IPC: H03D3/06
Filed: 1983-05-03
Abstract: An F.M. demodulator of the phase quadrature type for fail-safe operation and in particular for use in a railway signalling system.

Patent GB-2162333-A (GB)
Title: Recording spatially modulated light patterns
Inventor: SCARR R W A
IPC: G02F1/133
Filed: 1984-07-20
Abstract: A smectic liquid crystal layer 15 in the vicinity of or just below its isotropic phase transition temperature is illuminated with a spatially modulated pulse of high intensity radiation whose absorption gives rise to the formation of an equivalent thermal image. The radiation intensity is such that at least parts of the layer are taken by the radiation into the isotropic phase. During the ensuing cooling of the layer an electric field is applied. Those areas which have already reverted to the smectic phase remain optically scattering while those still in the isotropic remain optically clear when reverting to the smectic phase and thus the thermal image becomes 'frozen'. The initial temperature of the smectic liquid crystal layer is set by application of a pulse of light to the layer, or by ohmic heating of electrodes 13, 14, or by a combination of both. <IMAGE>

Patent GB-2179128-A (GB)
Title: Apparatus for cooling liquids
Inventor: PAXMAN NEIL ERIC
IPC: B67D1/08
Filed: 1985-06-18
Abstract: Liquid coolant passes through flow and return pipes 9, 13 and is arranged to flow through a tank 6 which contains a refrigeration coil 5. A thermostatic controller 10 continuously detects the temperature of the coolant liquid, and when the temperature rises above a first predetermined level, a valve 11 is controlled, to direct the coolant through the refrigerant tank 6. However, when the controller 10 detects that the coolant temperature is below a second predetermined level, it causes the valve 11 to direct the coolant through a by-pass pipe 12, rather than through the tank 6, so that there is substantially no further cooling of the liquid coolant. Thus, whilst the apparatus is in use, a circulating pump 14 for the coolant may operate continuously, and therefore does not suffer from repeated ON/OFF switching. Rather, the valve 11 is switched, and as a result of this, the compressor 2 for the refrigerant coil 5 needs to be switched ON and OFF only at relatively long intervals. <IMAGE>
