Patent GB-2035360-A (GB)
Title: Fat-continuous emulsions
IPC: A23D7/02
Filed: 1979-11-14
Abstract: A process for preparing fat- continuous emulsions, containing 15 to 35% of fat, comprises spraying an aqueous phase, until 65 to 85% is reached, into a liquid fatty phase while maintaining conditions of sufficient shear to increase the viscosity without giving rise to phase inversion, e.g. by spraying the aqueous phase into a pool of liquid fatty phase, after which the emulsion is pumped through a static mixer until a viscous emulsion is obtained, which is subsequently worked and cooled, thereby to obtain a droplet size of 4 to 20  mu m of at least 80% of the droplets.
Patent GB-2059697-A (GB)
Title: Improvements in or relating to modulated signal sources
IPC: H04L27/12
Filed: 1979-12-12
Abstract: In a modulator the modulation information from a digital data store 1 is arranged to operate a switch 8, which in the case of amplitude modulation (Fig. 4) produces pulses of carrier frequency and in the case of frequency modulation introduces phase or frequency transitions into a carrier frequency at a phase adder or at a variable divider in a control loop. The use of the digital data and the switch enables the modulation characteristics of the signal source to be exactly predictable and reproducible and it is not degraded by non-linearities of the kind introduced by conventional mixers. In amplitude modulation, carrier pulses are normally passed or blocked at the switch 8 in dependence upon the digital data. However, the modulation depth may be controlled by selector 10 by enabling an appropriate number of carrier pulses to be passed during the blocking phase. The switch 8 shifts all frequency components contained in the data stream to be centred around the carrier frequency and filter 5 passes the required sidebands. <IMAGE>

Abstract: A high pressure discharge lamp comprising a metal halide discharge tube (1) provided with an ignition electrode or with a preheatable electrode has tungsten coil(s) (2) connected in series therewith which we located so that the heat from the tungsten coil(s) effects the setting of the optimal temperature for the cold spot of the discharge tube (usually adjacent its ends) and its operating point. A tungsten coil may be provided at only one or at both ends of the discharge tube 1, and the coil(s) are incandescent so that they add to the light output of the lamp. A further incandescent coil may also be provided to give light when the discharge tube is inoperative. Heat reflecting layers 13, 14 of zirconium oxide may also be provided at the ends of the tube; alternatively the quartz body of the tube 1 may have its entire surface provided with an infrared reflecting layer. In a further embodiment, Fig. 5 (not shown), instead of a tungsten coil an incandescent halogen lamp is used at one end of the discharge tube. <IMAGE>
