Apparatus and methods for mixing and dispensing components. The methods and apparatus of the invention are particularly advantageous to mix the components of radiopaque bone cement and inject the resulting radiopaque bone cement into skeletal structures. The apparatus of the invention comprises: (1) a sealed mixing chamber for mixing components; (2) a dispensing chamber isolated from the sealed mixing chamber; (3) a controllable portal to open a flow path between the sealed mixing chamber and the dispensing chamber so that the dispensing chamber can receive the mixed components after they are mixed; and (4) a drive mechanism associated with the dispensing chamber to force the mixed contents from the dispensing chamber.

A spiral-type kneading machine for the preparation of flour-based mixtures comprises a non-rotating circular bowl and a spiral-shaped kneading tool rotatable inside the bowl. The spiral-shaped kneading tool has its axis substantially coincident with the axis of the bowl and occupies substantially the entire space contained within the bowl. The tool cooperates with a fixed member projecting upwardly from the bottom of the bowl and spaced from the central axis thereof.

A process and apparatus for the measurement of parameters in reactors having moving stirrers which contain probes in the reactor interior, wherein at least two probes connected via a multiplexer to a sensor signal amplifier by connecting cables located in the moving stirrers are installed on the surface of the moving stirrers, and the measurement data obtained by the probes are passed via the connecting cables to a sensor signal amplifier and from thence are passed on to an electronic evaluation unit by non-contact, inductive signal transmission by means of a contactless sensor tap.

An organic waste composting system is provided for rapidly, economically and naturally composting organic waste. A container having a gas impermeable floor, sides and top is provided with a gas inlet port and a gas exhaust port. An air floor is provided within the container, the air floor being gas permeable and impermeable to solids contained within the container. The system farther includes a mixing blade dimensioned so that shear forces produced by the blade when rotated within the organic waste are substantially equal to the viscoelastic forces of the organic waste particles. The mixing blade is dimensioned to further shear the waste to a size which increases its surface area-to-volume ratio without compacting it, thus providing suitable moisture distribution, particle distribution and air channels between particles.

Stirring apparatus including a stirrer having an mounting the stirrer at the attachment end and driving the stirrer in motion in operative association with a utensil defining a utensil surface and a utensil contacting member mounted onto the termination end of the stirrer and being orientatable with respect thereto so as to correspond to the configuration of the utensil surface in engagement therewith.
摘要:
A kitchen machine is provided with a base (3) and a motor housing (5) which is arranged on the base (3) and in which an electric motor (27) is accommodated. On the base (3) next to the motor housing (5), an open bowl (9) can be placed, journalled relative to the base (3). A transverse arm (17) can be coupled on the motor housing (5), which arm extends to above the bowl (9). A tool (19) can be placed in the bowl (9) and can be coupled to a transmission (25) which is arranged in the transverse arm (17) and can be driven by the electric motor (27). The bowl (9) can be driven into rotation by a pinion (21) which is also coupled to the transmission (25). The pinion (21) is displaceable along its axis of rotation relative to the transverse arm (17) and is displaced from a first into a second position through engagement with a toothed rim (23) of the bowl (9) when the transverse arm (17) is placed on the motor housing (,5). In the first position of the pinion (21), a rotary switch (69) is blocked in its zero position by a blocking mechanism (71) coupled to the pinion (21), so that the electric motor (27) cannot be switched on, whereas the rotary switch (69) is released by the blocking mechanism (71) with the pinion (21) in the second position when the transverse arm (17) is locked to the motor housing (5) by a locking mechanism (117). The kitchen machine can thus only be switched on when both the bowl (9) and the transverse arm (17) have been correctly positioned, so that the possibility of injury of a user of the kitchen machine with the rotating parts of the kitchen machine is substantially elminated.
摘要:
A processor has a working receptacle with a part-spherical internal wall. There is a working element which can execute either simple rotary motion about a single axis or planetary motion about two axes which intersect at the geometric center of the part-spherical internal wall. There are control means for enabling simple rotary motion or planetary motion to be effected.Dough is worked by hydrating the mix and then completing development at a substantially greater energy input rate. The hydration stage can be considered as being carried out at such an energy input rate that substantial relaxation of the dough occurs, the development completion stage being considered to be carried out at an energy input rate at which no substantial relaxation of the dough occurs. Alternatively, in a more specific idea, the hydration stage is carried out using a working element with a planetary motion and the development completion stage is carried out using a working element with simple rotary motion.
摘要:
Abrasive-containing tobacco slurry is homogenized by passing radially outwards between the facing surfaces of two closely adjacent coaxial rings of tungsten carbide to impinge violently against a tungsten carbide surface surrounding the rings. The occurrence of local areas of wear in the facing surfaces is minimized by rotating one ring relative to the other.
