Abstract
460,825. Inductances; bobbins or spools. BOSCH AKT.-GES., R. June 22, 1936, No. 17256. Convention date, June 22, 1935. [Class 38 (ii)] [Also in Group IX] Cores for tuning and like coils comprise several parts a, a<1>, a<11 >held together by an insulating body moulded externally thereon. The insulating body may be sprayed on to the core parts which may be provided with recesses into which projections b on the insulating body fit. Alternatively the core a may be entirely surrounded by the insulating body g which thus holds the core parts together. The insulating sheath g and the hollow core part a may be provided with an internal screw thread h so that a tuning screw may be screwed in and out the core. Holes i for the coil holding screws may be provided in extensions of the insulating body.
