Patent EP-0508812-A1 (EP)
Inventor: TURUNEN AIMO
IPC: H01P1/205
Filed: 1992-04-10
Abstract: A dielectric filter comprises several ceramic resonator blocks (30,40) in contiguous relationship. The individual resonator blocks are made of different ceramic materials having respectively different dielectric constants. Consequently, the resonator blocks may all have the same physical height, while having different resonant frequencies. Thus an optimum physical size may be selected for the resonator blocks, particularly with regard to packing density.

Abstract: A circular horn antenna having a wide beam and an extended bandwidth of 6-18 GHz, for use with signals having orthogonal polarization planes. The horn (5) is required to adapt to a standard square polarizer (1) having differential delay ridges (9) and is itself provided with corresponding metal ridges (13) which are continuous with the polarizer ridges (9). These horn ridges (13) are tapered at the mouth end of the horn to cooperate with the reverse taper of a dielectric cone (19) of cruciform cross section. This dielectric cone (19) has an axial hole (22) throughout the cone (19) and a larger axial cylindrical recess (24) in the base of the cone (19). A dielectric lens (27) is fitted to the mouth of the horn (5) for beam widening and matching purposes. The lens (27) has a large bore in the rear end to receive the circular horn mouth and a small bore (23) in the front end. The two bores are separated by a thin wall of dielectric material (29) contributing significantly to the matching. A circular horn antenna is thus provided having a very wide bandwidth (6-18 GHz), good matching and return loss over the band, while at the same time achieving good power handling capacity and weight reduction.

Abstract: Such a charging circuit comprises an alternator (12) driven by the engine, a rectifier bridge (20) and a regulator (28). The invention essentially consists in arranging the regulator (28) in the same casing as the ignition and injection control circuit (61) of an injection engine. This removes the regulator from extreme temperatures and intense vibrations which it underwent in the alternator framework. The reliability of the charging circuit is considerably improved and its connection is significantly simplified.   <IMAGE>

Abstract: In a step conveyor (not shown) for fresh boxless sand moulds (not shown) and comprising at least two sets of interdigitating parallel bars (3,4) adapted to support and move said sand moulds, the main novel feature consists in that the top of each bar (3,4) is covered or coated by a layer of a material with a considerably lower thermal conductivity than that of steel, in the example shown consisting of a top rail (9) secured to a base member (7) by means of screws (10), said top rail being made of a suitable synthetic resin, such as low-pressure polyethylene with ultra-high molecular weight. 
     With this arrangement, the tendency for moisture from the fresh sand moulds to condense on the conveyor bars (3,4) is considerably reduced or eliminated, thus reducing or eliminating the tendency for sand from the moulds to adhere to the conveyor bars.
