[Class 40 (v)] A wireless aerial unit, designed to give improved signal pick-up together with a reduction in size of aerial in many cases, consists of an aerial wholly embedded or enclosed in a material having a higher magnetic permeability and dielectric constant than air. As shown, a flat frame aerial such as is used in portable receivers, has the individual turns cemented together to form a pliable tape 1 with connecting leads 2. Two similar blocks 3 and 4 formed of synthetic resin impregnated with iron dust, have channels 5 and also outlet channels to receive the winding 1 and connecting leads 2. The blocks are bolted together with the winding inside by means of bolts passed through holes 6 to form the complete unit. Other aerials, for example, a spiral aerial with one free end and approximately a quarter-wavelength long, may be similarly enclosed. In another embodiment, the aerial winding can be embodied as an inset in a moulding of synthetic material impregnated with iron dust. It is possible to apply the invention to a dipole and parabolic reflector, the dimensions of the whole system being reduced by a factor depending on the constants of the material in which it is embedded.

Abstract: 499,741. Regulating. DAIMLER-BENZ AKT.-GES. Sept. 5, 1938, No. 25950. Convention date, Sept. 4, 1937. [Class 7 (vi)] In engines wherein an anti-knock liquid is supplied when the supercharger is brought into action, means are provided for preventing increase of the charging pressure when the anti-knock liquid is not available, due to failure of the supply. The Figure shows an engine with a supercharger 4 supplying the air intake 5 and controlled by a clutch 3, the anti-knock liquid being supplied from a tank 15 by a pump 12 controlled by a clutch 13. The pressure of the liquid supplied by the pump 12 is made to act on a piston 20 connected to a throttle 23 on the intake 5. When the clutches 4 and 13 are operated, the supercharger and pump 12 are started to supply the increased charging pressure and the anti-knock liquid. If the supply of the latter fails, a spring 19 acting on the piston 20 opens the throttle 23, so that the air supplied by the supercharger escapes. The anti-knock liquid is injected through pipes 16 to inlet pipes 5<1>, the main fuel being supplied by a pump 8 and pipes 9 to the injectors. An altitude capsule 21 may also be connected to the throttle 23 on aircraft. Instead of cutting out the auxiliary pump 12, the liquid supplied thereby may be controlled by a byepass.
