Abstract: A method and a device for making pieces of ice where water in a container is frozen into ice. A helically threaded shaft extends through the container so that the ice surrounds the shaft and is engaged by the helical thread of the shaft. The threaded shaft is rotated with respect to the ice so that the ice is moved toward a cutting member carried by the threaded shaft. Subsequently, the ice is shaved by the cutting member.

Abstract: A shaver includes a shaving unit having e.g., three shaving elements. Each shaving element accommodates a cutter member for cutting off hairs. Each shaving element further accommodates a gear wheel which is part of a transmission for coupling a drive shaft for driving the cutter member to an output shaft of a motor of the shaver. A top side of a space where the gear wheel is located is covered by a partition, where only the drive shaft extends through this partition. Each shaving element can be individually opened by removing a top portion of the shaving element, including the cutter member, from a base portion of the shaving element where the gear wheel, the drive shaft and the partition are located. An opening system may be provided to open all the shaving elements in one action by reversal of the direction of rotation of the output shaft, for example.

Abstract: Actuator arrangement with an actuator (8), a reference mass (22), a spring (24) and a first sensor (26; 42, 43; 32, 36). The actuator (8) applies a force between a first object (2) relative to a second object (16; 54). The reference mass (22) is, in use, supported by a third object (16; 56) by means of the spring (24). The first sensor (26; 42, 43; 32, 36) generates a first distance signal that depends on a first distance (z2; z5,z6; z3,z4) between the reference mass (22) and the first object (2) and is provided to a controller (6) to actuate the actuator (8).

Abstract: The fluid-dispensing system is used in a personal care appliance, such as a power toothbrush. The dispensing system includes a strip of discrete, fluid-containing packets, a compressible sealing member and a hollow needle for puncturing the packets, the hollow needle being connected to a workpiece such as a brushhead via a connecting line. An actuation assembly includes a piston which moves successive packets against the sealing member, initially sealing the packet thereto. Further pressure results in compression of the sealing member and puncturing of the packet by the needle, with fluid being forced by piston pressure from the packet into the hollow needle and then to the connecting line for delivery to the workpiece.

Abstract: A shaver includes a shaving unit having e.g., three shaving elements. Each shaving element accommodates a cutter member for cutting off hairs. Each shaving element further accommodates a gear wheel which is part of a transmission for coupling a drive shaft for driving the cutter member to an output shaft of a motor of the shaver. A top side of a space where the gear wheel is located is covered by a partition, where only the drive shaft extends through this partition. Each shaving element can be individually opened by removing a top portion of the shaving element, including the cutter member, from a base portion of the shaving element where the gear wheel, the drive shaft and the partition are located. An opening system may be provided to open all the shaving elements in one action by reversal of the direction of rotation of the output shaft, for example.

Abstract: A method and a device for making pieces of ice, wherein water in a container (1) is frozen into ice. A helically threaded shaft (7) extends through the container (1), so that the ice (10) surrounds the shaft (7) and is engaged by the helical thread (18) of the shaft (7). The threaded shaft (7) is rotated with respect to the ice (10), so that the ice (10) is moved toward a cutting member (9) carried by the threaded shaft (7). Subsequently, the ice (10) is shaved by the cutting member (9).

Abstract: A device for shaving hairs growing from skin including a base portion having a grip, a shaving head which carries at least one cutting member having at least one cutting edge, and an actuator for effecting a periodical motion of the cutting member relative to the base portion to improve the cutting action of the cutting member. The shaving head is pivotable relative to the base portion about a pivot axis and the periodical motion of the cutting member is a periodical motion relative to the shaving head. The position and orientation of the geometrical path of the periodical motion of the cutting member relative to the skin is well-defined, so that the risk of skin irritations and skin injuries is considerably reduced.

Abstract: A shaver has a shaving unit which comprises three shaving elements (6), wherein each shaving element (6) accommodates a cutter member (9) for cutting off hairs. Each shaving element (6) further accommodates a gear wheel (16) which is part of transmission means for coupling a drive shaft (17) for driving the cutter member (9) to an output shaft of a motor of the shaver. A top side of a space (23) where the gear wheel (16) is located is covered by a partition (22), wherein only the drive shaft (17) is extending through this partition (22). Each shaving element (6) can easily be opened by removing a top portion (27) of the shaving element (6), which comprises the cutter member (9) from a base portion (26) of the shaving element (6) where the gear wheel (16), the drive shaft (17) and the partition (22) are located. An opening system (102, 104, 112, 200) may be provided to open all the shaving elements (6) in one action by reversal of the direction of rotation of the output shaft (15, 15a).

Abstract: An electro-magnetically controllable beam deflection device for use in an optical system for deflecting a radiation beam obtained from a radiation source, in particular for use in video players. The deflection means may for example comprise a pivoting mirror, or an assembly of a plano-concave and a plano-convex lens which with their concave and convex surfaces face each other, and can perform pivoting movements at a small distance from each other. The deflection means is connected to frame by means of an integrated plastic bearing component. The bearing component has a local portion of small cross-section which under the influence of the control forces exerted on the deflection means, is relatively readily deformable. This portion may for example take the form of an integral hinge or of a thin cylindrical portion.
