  • Patent number: 6973780
    Abstract: The invention relates to a controller for a hydraulic press, comprising a pressing cylinder (1), a reservoir (2), a valve group (3), a pressure medium reservoir (7) and a hydraulic pump (6), connected together by means of a cylinder line (4), a reservoir line (5) and a tank line (8). According to the invention, a pressure converter (9) is arranged on the valve group (3), which may operate as a pressure amplifier or pressure reducer. The particular mode of action of said controller is achieved whereby the valve group (3) comprises a pre-press valve (11), a low-pressure chamber outlet valve (12), a low-pressure chamber inlet valve (13), a main press valve (14), a closing valve (15), a pressure release valve (16) and a 3-way valve (17), which may be operated by a particular control sequence. Said invention is applicable in hydraulic presses and of particular advantage in presses for the forming of ceramic pieces such as tiles.

  • Patent number: 6895700
    Abstract: A soleplate for a clothes pressing iron, composed of: a metal sheet having a lower surface that will be directed toward fabrics to be ironed, a lower surface layer that extends form the lower surface and an interior region that is separated from the lower surface by the lower surface layer, the lower surface layer being mechanically hammer-hardened, or work hardened, to have a hardness greater than the hardness of the sheet prior to being mechanically hardened; and a coating that is hard and resistant to scratching covering the lower surface.

  • Patent number: 6807755
    Abstract: The invention relates to an iron. The inventive iron consists of a liquid container (6) comprising an inlet (7) which is fitted with means of receiving and guiding the liquid through said opening towards the container. Preferably, the aforementioned means comprise a part (9) in the form of a slide valve or chute. Moreover, said means, which pass through the opening, can move in translation between a first open position, whereby the liquid can be introduced, and a second closed position, whereby the means are retracted into the iron in order to close the opening (7).

  • Publication number: 20040093766
    Abstract: A shoe with a foot-massaging effect comprises a sole, optionally with a heel, and a top material. A cushion containing a massage element and/or active medical agents is provided in the interior of the shoe, above the sole, said cushion has a flexible base panel on the bottom, corresponding to the shape of the sole, and an elastic protective nonwoven fabric on the top, the latter being permanently connected to said base panel. A toe cap containing active medical agents can also be provided in the tip of the shoe. These measures result in a fairly significant foot-massaging effect and at the same time, enable the show to be used without creating an odor.

  • Patent number: 5987681
    Abstract: An electric toothbrush with a handle, a brush head and a shank which connects the handle to the brush head. A rotary motor is arranged in the handle and drives an unbalanced mass. The unbalanced mass driven by the motor is supported on one side or on both sides in the shank close to the brush head and is driven via an extended drive shaft, preferably an intermediate shaft, by the motor.

  • Patent number: 5651157
    Abstract: An electric toothbrush having a handle with a cavity therein, a motor mounted in the cavity of the handle and having a rotatable shaft, a brush head, and a shaft arranged to connect the brush head to the handle. An eccentric weight is mounted to the motor shaft so as to rotate eccentrically when the motor shaft rotates so that the brush handle vibrates. A further weight is mounted to the shaft so as to be axially movable by a manipulator for adjusting vibration of the brush head.
