A method of controlling a portable appliance includes measuring an input current supplied to a motor of the portable appliance and measuring a rotational speed of a shaft of the motor. The method also includes determining a current limit based on the rotational speed of the shaft using a substantially continuous function which relates a domain of rotational speeds to a range of current limits. The method further includes reducing, when the input current exceeds the current limit, the rotational speed of the shaft incrementally along the substantially continuous function until the input current is approximately equal to the current limit.

A small, non-powered, handheld and finger-manipulated mixing device adapted for stirring or mixing liquids or liquid/solid combinations in relatively small volume containers. The mixing device has an elongated rod-like main body with an agitation member disposed on its distal end. The main body is provided with a bounded shaft segment that is bounded proximally and distally by transition shoulders of greater diameter than the bounded shaft segment, thus providing a region to receive the thumb and finger of the user to spin the main body, with the transition shoulders preventing excessive movement in the axial direction during rotation.

The invention relates to a process of manufacturing a dental milling block with a homogeneous color and/or translucency gradient. This process comprises the steps of providing a mold with a cavity having a z-direction and an x/y-direction, filling the cavity partially with a first powder up to a height H1, the first powder having a volume VP1 with a top and bottom surface, introducing a second powder on top of the first powder up to a height H2, the second powder having a volume VP2 with a top and bottom surface and, the top surface of the first powder being in contact with the bottom surface of the second powder and forming an intermediate region, providing a mixer unit with at least one rotatable mixing element, introducing the rotating mixing element in z-direction into the intermediate region, mixing the powder located in the intermediate region by rotating the mixing element, removing the rotating mixing element from the powder, compacting the powder, optionally applying heat to the compacted powder, the first powder differing from the second powder by its physical properties and/or chemical composition and/or color. The invention also relates to a process of producing a dental restoration using dental milling block obtainable according to this process.

The present invention relates to a kneading member (107) for a device for kneading a dough, comprising: —a mounting disc (109); —a kneading tool (111) for mixing the ingredients which constitute a dough, comprising: —an upper portion (121), extending from said mounting disc, —a mid-portion (123), in the extension of said upper portion, and —a lower portion (125), in the extension of said mid-portion. The kneading member (107) according to the invention is noteworthy in that the kneading tool (111) consists of a circular helix, the angle of winding of which is non-constant between said upper, mid- and lower portions of the tool (111) and in that the angle of winding of the lower portion (125) is less than that of the mid-portion (123). The invention also relates to a kneading device fitted with such a kneading member.

A small, non-powered, handheld and finger-manipulated mixing device adapted for stirring or mixing liquids or liquid/solid combinations in relatively small volume containers. The mixing device has an elongated rod-like main body with an agitation member disposed on its distal end. The main body is provided with a bounded shaft segment that is bounded proximally and distally by transition shoulders of greater diameter than the bounded shaft segment, thus providing a region to receive the thumb and finger of the user to spin the main body, with the transition shoulders preventing excessive movement in the axial direction during rotation.

A system for cooling and mixing a food or drink in a pod includes an apparatus for cooling and mixing a food or drink in a pod, the hermetically sealed pod, and a magnetic stir bar. The apparatus has a cooling system defines a recess sized to receive the pod. The apparatus includes a magnetic stirring assembly for rotating the magnetic stir bar and an actuator operable to create a vibration in the recess, The magnetic stirring assembly is operable to generate a magnetic field in the recess of the cooling system and has a rotating magnet. The magnetic stirring assembly rotates the immersed magnetic stir bar in the pod causing the food or drink to rotate to the wall of the pod to increase heat transfer from the food or drink to the cooling system.

The invention relates to a food processing system (100) for preparing an edible mass of a food product starting from a raw food material, the system comprising: one or a plurality of food containers (20), each one comprising a raw food material in form of dehydrated material and/or paste and/or chunks; one or a plurality of dispensing and reconstituting chambers (10), each chamber being associated to at least one food container (20), each of the chambers (10) comprising a variable and/or exchangeable reconstitution and deposition device configured for hydrating and/or structuring and/or reconstituting in batches the raw food material provided by the one or more food containers (20) in order to create a homogeneous edible mass of food product, the device being further configured to deposit in-line with a controlled flow the edible mass of food product once prepared. The invention further relates to a method for operating a food processing system (100) as the one described in order to prepare an edible mass of food product starting from raw food material: the information on the kind of raw food material and on its processing is retrieved from identification means on the one or more food containers (20) and/or from a connected database, in order to process the raw food material in the one or more of the dispensing and reconstituting chambers (10) according to a certain recipe, acting on the hydration ratio and/or mixing speed and/or mixing time and/or temperature and/or viscosity and/or texture

A mixer for synthetic quartz includes a mixing barrel (1), a power transmission system (2), a mixing system (3), and multiple material receiving receptacles (4). The power transmission system is provided above the mixing tank. The mixing system is provided inside the mixing tank. The power transmission system is used to drive the mixing system to move. An opening is arranged at each of two ends of the material receiving receptacle. The multiple material receiving receptacles (4) are arranged at a top portion of the mixing tank, and end portions of two adjacent material receiving receptacles are spaced apart from each other without contact there between. A resin experiences low flow resistance in the material receiving receptacle, and thus can fall smoothly without accumulating in the material receiving receptacle. Moreover, the material receiving receptacle can be cleaned easily.
