Patent GB-2046543-A (GB)
Title: FM receivers
IPC: H03D7/00
Filed: 1980-03-06
Abstract: In a radio or television receiver, a frequency modulated signal (FM) is fed to a D-flip-flop (4) together with a clock signal at a frequency  f1 = fT + 2fg + 2dfmax where fT is the TV sound carrier frequency or the radio intermediate frequency, fg is the audio cut-off frequency and dfmax is the frequency deviation. The output is fed via an AND gate (5) coupled to a second clock (2) and operating as a digital mixer, to a period measuring circuit (30) where the time frequency deviation value of the signal in both magnitude and sign is determined by a period-frequency converter (6) (including a ROM). The output of the period-frequency converter (6) is fed via a down-counter (7), clocked via a third clock generator (3) to an RS flip-flop (8), to derive a pulse width modulated signal wherein the pulse widths are proportional to the instantaneous frequency deviation of the signal (FM). This signal is then fed via AND gates (12, 13) and inverter (14) to an audio power output stage including a pair of VMOS transistors (15, 16). <IMAGE>

Title: Improvements in or relating to fuel supply units
IPC: H02K15/12
Filed: 1980-05-01
Abstract: A method for the production of a fuel-resistant fuel supply unit, preferably an electrically driven fuel pump, and also a fuel supply unit are proposed, wherein resin break-aways may be avoided at the armature winding. For producing such a fuel- resistant and strengthened armature winding (4), a lacquered wire with a baked lacquer coating is used as the winding wire, which coating is so softened by temperature effect that, after the winding has cooled, a firm bond is provided at the mutual contact points of the wires. For the baked lacquer coating, synthetic resins on a polyamide basis (thermoplastics), or on a polyester or epoxy basis (duroplastics) are preferred. As a result, the impregnation of the armature winding (4) may remain stable even under the action of fuel and no longer tends to break away. <IMAGE>

Patent GB-2071417-A (GB)
Title: Process for Winding Capacitor Dielectric Materials
IPC: H01G13/02
Filed: 1981-03-02
Abstract: The present invention relates to a method for manufacture of capacitors of the wound roll type, using alternate layers of conducting and dielectric sheet material. In the prior art, during the winding of such capacitors with high dielectric strength material, static electricity build-up on the dielectric material has caused difficulty in obtaining uniform rolls, and particularly interfering with the winding of loose rolls to be employed in fluid-filled capacitors. The method of the present invention provides for coating with dielectric sheets with electrically-conductive liquid before winding, with removal of the liquid after winding. The conductive liquid eliminates static electric charges, permitting uniform winding. After removal of the conductive liquid, dielectric liquid can easily penetrate the roll. The preferred conductive liquid is a mixture of water and an alcohol.
