A device for storing and mixing bone cement components. The device includes a housing, a safety device, and a vacuum indicator. The housing defines a mixing chamber configured to store a first bone cement component therein. In a first safety position, the safety device prevents contact between the first bone cement component and a second bone cement component in the mixing chamber. In a second safety position, the safety device permits contact between the first and second bone cement components in the mixing chamber. The vacuum indicator restricts movement of the safety device from the first safety position to the second safety position when in a first vacuum indicator position. The vacuum indicator permits movement of the safety device from the first safety position to the second safety position when in a second vacuum indicator position.

A blending system is shown and described herein. The blending system may include a base including a motor, a blade selectively and operably engaged with the base, where the motor rotates the blade, a container having an open end and a lid configured to cover the open end. The blending system may also include an interlock system that may include a plurality of induction coils positioned on the base and the container and be in electrical communication with at least one lid sensor, wherein the power is translated through the induction coils to engage a switch device to complete a power circuit to allow a user to operate the motor of the blender.

A blender collar assembly including a plunger moveable between a lower position where a blade assembly is prevented from coupling with a motor, and an upper position where the blade assembly is able to couple with the motor. The plunger includes an arm extending upward and having a u-shaped feature, and a protrusion associated with the u-shaped feature. The assembly further includes a concentric interlock ring rotating responsive to rotation of a blender jar. The interlock ring including a first portion engaging the u-shaped feature preventing the plunger from moving upward, a second gap portion not engaging the u-shaped feature enabling the plunger to move upward and downward within the collar, and a key engaging a protrusion of the blender jar as the plunger moves upward preventing the interlock ring from rotating while the second portion is rotationally aligned with the u-shaped feature.

Syringe for dispensing foam having a syringe barrel, a nozzle and a bore to receive a syringe plunger having a front end and a back end. The syringe plunger includes at the front end thereof a waste container defined by a cylindrical side wall, a front end wall and a rear end wall, the walls being arranged such that an external cylindrical surface of the walls forms a seal with an internal surface of the syringe barrel. The waste container has an inlet aperture in the front end wall which is in communication with the syringe nozzle when the plunger is fully depressed into the syringe barrel. The waste container further has a hydrophobic vent in the rear end wall thereof which allows air to escape from the waste container while substantially preventing foam from escaping the waste container when the syringe is in use.

A mixing apparatus (1) for mixing slaughter offal with a preservative agent, the apparatus comprising an offal collection tank (3) with a bottom (4) provided with a discharge opening (5) connectable to a closable discharge, an agitator (8) extending into the offal collection tank, and a pump unit (9) operatively connectable to the discharge, wherein the apparatus further comprises a preservative reservoir (7) mounted on top of the collection tank (3). A collection and preservation system is provided, wherein the addition of preservation agent can be strictly controlled, can easily and quickly be installed and connected when it is to be used. After use, the system is easily removed and cleaned.

A domestic carbonation appliance has a replaceable CO.sub.2 cylinder and accepts a refillable bottle with a removeable cap. The cap can cooperate with a carbonation head of a domestic carbonation device but lacks bayonette or thread features for engaging the carbonation head. The device provides for one-touch carbonation.

A laboratory mixer for mixing a sample and a diluent in a bag. An enclosure defines a mixing chamber, and at least one movable mixing element is retained for mixing the sample and the diluent within the bag. At least one liquid detector is retained relative to the enclosure for detecting liquid leaked from the bag. The sensor can be a capacitive, inductive, or optical sensor. The sensor can be a conductivity sensor with two electrodes shaped like combs and a gap less than or equal to a diameter of a drip of diluent solution. A ledge with a low point can be retained by an access door. The sensor or sensors can be disposed adjacent to the access door, on a mixing element, in direct contact with the bag, or on a tank. An alarm and cessation of operation can be triggered upon a detection of leaked liquid.
