Abstract:
The invention concerns a hand-held mixing beater comprising a drive motor (6), two rotary coupling elements (38, 16) associated with the motor (6) and designed to receive a beater (10) and a mixing arm (25) respectively, and an electric switch (52) actuated by a knob (48) mounted rotating on a rotation shaft (50) and occupying a neutral position and several switching positions for the motor to operate without interruption. The invention is characterised in that a coil spring (66) is mounted concentric to the rotation shaft (50) of the knob (48) and has a free end (68) and a fixed end (67) linked to the knob (48), and a safety part (70) is mounted mobile between a neutral position in the presence of the mixing arm (25) and wherein the free end (68) of the spring (66) is pressed (72) on the safety part (70) so as to permanently tension the spring (66), and a retracted position in the presence of the beater (10) and wherein the pressure (72) of the safety part (70) is cleared so as to permanently release the spring (66).
Abstract:
In a kitchen appliance (1) comprising a container (2) and a drive unit (9) adapted to be placed onto the container (2) and having a housing (10) which accommodates a motor (21) of the drive unit (9), the housing (10) carries in the area of its housing cover wall and actuator grip (26) for actuating a retaining device (40) arranged in the housing (10) and, by moving the actuator grip (26) from a rest position into an operating position, the retaining device can be set from a disengaged position into a retaining position in which the drive unit (9) and the container (2) are coupled to one another so as to form a firmly coupled assembly with the aid of the retaining device (40).
Abstract:
In a domestic appliance (1) for making ice-cream, comprising a motor (8), a stirring tool (12) drivable by the motor (8), and switching means (69) for starting a first mode of operation of the domestic appliance (1), in which mode the stirring tool (12) can be driven with a speed n (21 r.p.m.) within a speed range, the switching means (69) are adapted to start a further mode of operation of the domestic appliance, in which further mode in which the stirring tool (12) can be driven with at least one further speed (71 r.p.m.) within a further speed range, and there has been provided a time control device (66) by means of which the drive of the stirring tool (12) with the further speed n (71 r.p.m.) can be limited to a given time internal (T).
Abstract:
The invention pertains to a food processor (1) with a mixing vessel (10) and a drive mechanism (75) for an agitator (70) in the mixing vessel (10), where the mixing vessel (10) can be heated in its lower region (65) and held in a narrowly enclosing seat (13) that has a substantially cylindrical wall region. To improve the design of this type of food processor (1) so that heat is transmitted evenly and the mixing vessel can be removed easily after the food processor (1) has been used, the invention proposes that the cylindrical wall region can be adjusted to change its diameter and thus ensure a flexible nonpositive fixture of the mixing vessel (10).
Abstract:
A method of prilling or spray drying comprising calculating and controlling the viscosity of a shear-thinnable fluid stream at a particle-forming section of a dispersion device. The method comprises measuring the static head of fluid in the dispersion device, providing a pressurized blanket of inert gas over the fluid, mechanically agitating the fluid in the dispersion device, calculating the viscosity at the particle-forming section and controlling the viscosity by adjusting the speed of mechanical agitation.
Abstract:
Disclosed herein is a system and method for adequately seeming the currently available metal and plastic containers for paint and other fluids as well as other foreseeable containers in an automated fashion without crushing or damaging the containers, without using any special adapters for particular container types and without operator intervention. To avoid crushing a plastic container, the disclosed system and method takes advantage of the compressibility of these less rigid plastic containers. It has been found that a plastic paint container can be safely clamped in place without structural damage if the clamp plate travel after engagement with the top of the container is limited to a certain value, for example, about 5/16". When the compression amount is limited or controlled, the plastic container will not move or will move very little during a three minute violent shake cycle. Some conventional containers are not readily compressible, such a metal cans, drums or the larger (five gal) plastic buckets or pails. To address the issue of these containers being used with the same machine as the new plastic containers, an increase in current or voltage drawn by the clamping motor is monitored after initial contact with the top(s) of the container (s), and if the increase reaches a threshold value, the motion of the upper clamping plate is stopped and an appropriate holding force is maintained.
Abstract:
A fully automatic electronic milkshake mixer (10, Figure 1) in which an operator sets scoop dial control (34, Figure 1), based upon the number of scoops of ice-cream or related products placed in mixer cup. The mixer cup (28, Figure 2) rotates automatically by motorized lower drive wheels (48, Figure 1), and a top cup rim container guide/wheel assembly (54, Figure 1) engages mixer cup upper lip (56, Figure 2). Different sized mixer cups rotate perfectly, for faster, more complete mixing. The mixer automatically shifts from low to high speed (anti-splash feature), and turns off automatically when milkshake is done. A "ready" light (42, Figure 1) illuminates, and a chime (68, Figure 3) sounds volume control and on/off being adjustable. "Manual" momentary pushbutton (32, Figure 1) allows manual control of mixing speed and time, if desired, while cup rotates. For next milkshake, electronic mixer returns to fully automatic mode.
Abstract:
The invention relates to a program controlled stirrer for producing pharmaceutical or cosmetic recipes, comprising a stirring unit (1) which consists of a stirring tool which engages with a mixing receptacle. According to the invention, the stirring unit is coupled to a micro-processor (5) which determines the length of stirring time and stirring speed at the stirring unit (1) in a program-controlled manner. The micro-processor executes a data-processing program with the following steps: input of (11) variable data; input of (11) constant data; determination (12) of the length of stirring time and stirring speed in order to produce the desired amount of the recipe by combining the variable and constant data; conversion of the determined length of stirring time and stirring speed into corresponding first current or voltage values; control of the stirring unit with said first current or voltage values. Preferably, the size of the receptacle is inputted as variable data, whereby the data-processing program calculates the number of necessary rotations of the stirring tool using the constant data stored in the data memory, then controls the stirring unit correspondingly.
