Abstract: A grinding device, particularly for grinding pepper or salt grains, comprises a container for the grains, a grinder positioned on the bottom of said container, a battery-fed electric motor, a reduction unit with high gear ratio, and a drive shaft connecting the reduction unit to the grinder and crossing said container. Said device is formed of two disengageable bodies, one of which consists of a motor unit comprising the motor, the reduction unit, the feed battery and a control push-button, and the other of which consists of a container having a rotary grinder mounted on its bottom, one end of the drive shaft being fixedly connected to the grinder. In said device, the other end of the drive shaft and, respectively, the outlet gear of the reduction unit have reciprocal connection means apt to be disengaged.

Abstract: An electric heating and drying apparatus, of the type comprising, housed in a box-type body having at least partially open walls, a heating resistance and a fan arranged to blow air through said resistance towards an outlet opening, said box-type body being mounted on a support base on which it is adjustably positioned, said base comprising floor resting means and wall connection means. According to the invention stop means are provided, operating between the box-type body and the base, which stop means, when the base is resting on the floor, assume one position determining rigid fixing of the body to the base without the relative position of these latter being able to undergo adjustment, and which, when the base is connected to the wall, assume at least one position which allows the body to be freely adjusted relative to the base.
