A pipetting apparatus and method for pulsed dispensing of small metered-liquid doses of no more than 1 μl. The apparatus includes a pipetting conduit at least partly filled with working gas, a pressure-modifying apparatus for modifying the pressure of the working gas, and a control apparatus for applying control to the pressure-modifying apparatus. The control apparatus can control the pressure-modifying apparatus so as to generate in the pipetting conduit, with respect to a reference holding pressure in the pipetting conduit which is necessary for immovable holding of the metered-liquid quantity, an overpressure pulse having a pulse duration of no more than 40 ms.

The invention concerns a dosing pump for moving a fluid, comprising a dosing head in which there is a dosing chamber and a displacement element reciprocatable between a first and a second position, wherein the displacement element delimits the dosing chamber, and the volume of the dosing chamber in the first position of the displacement element is greater than the volume of the dosing chamber in the second position of the displacement element, wherein the displacement element is coupled to a linear motor by way of a stroke element in such a way that in operation of the linear motor the stroke element performs a forward stroke and a return stroke in a housing in a direction of a movement axis with a stroke length h and the displacement element is reciprocated between the first position and the second position. To provide a dosing pump and to improve dosing pumps which are driven with a linear motor it is therefore proposed according to the invention that the stroke element has a cross-sectional area Q perpendicularly to the movement axis, wherein the square of the stroke length h is at least forty times greater than the cross-sectional area Q.

A system includes a flow sensor contained within a flow sensor housing, a base, and a seal. The base houses a controller that generates at least one operation modification signal, and the flow sensor is separable from and mountable onto the base. A bottom surface of the flow sensor housing includes the seal. The seal forms a liquid-tight engagement between the flow sensor housing and the base when the flow sensor is mounted onto the base.

Presented and described herein is a stroke system (1) for dosing a fluid from a container (3), comprising a piston pump (5) with a piston (7), so that a fluid can be dosed from a container (3) by displacement of the piston (7), and a temperature control device (29) for controlling the temperature of the fluid to be dosed by means of the stroke system (1).

A medicine dispensing device, configured to contain a liquid medicine to be dispensed by the medicine dispensing device and having a plurality of dosing indicia spaced apart from each other around and in relation to a circumference of a surface of the medicine dispensing device, each dosing indicia being of a different height relative to a reference level and corresponding to different dose of the liquid medicine.

The invention relates to a proportional volumetric doser (10) comprising a motor (20) to which a pump (30) is connected, which pump (30) comprises a tubular sleeve (80) inside which a cylinder (85) is housed in which a small doser piston (62) slides, mechanically connected to an output shaft of the motor (20), wherein an inner surface of the cylinder (85) and the small piston (62) partially define a dosing chamber (48) of an auxiliary fluid to be mixed in the motor (20) in a prefixed amount with the main fluid, where said cylinder (85) has a threaded outer portion that meshes with a threaded portion of a ring nut (70) so that a rotation of the ring nut (70) causes an axial translation of the cylinder (85) and the variation of the volume of the dosing chamber (48), said proportional volumetric doser (30) being characterized in that the sleeve (80) comprises a locking system (100) configured to mechanically lock the cylinder (85) with respect to the tubular sleeve (80) by creating a shape constraint.

A Substance Dispenser and a Method of Providing a Substance Dispenser The invention provides a substance dispenser for dispensing a metered amount of a substance such as a cream or gel, other viscous or non-viscous substance, the dispenser comprising: a first housing member defining a handle for the dispenser; a cream containing chamber arranged to slide telescopically with respect to the handle member, the cream containing chamber having a nozzle opening at a first end, from which cream is, in use, dispensed; a bearing at the second axial end; and a shaft rotatably fixed with respect to the handle and arranged to pass through the bearing such that upon rotation of the handle with respect to the cream containing chamber, the cream containing chamber and the handle move telescopically with respect to each other such that, the substance containing chamber moves axially within the handle to force cream through the nozzle opening, wherein movement of the handle with respect to the cream containing chamber is indexed so as to dispense a predetermined volume of cream in dependence on a rotation thereof.

A fluid dispenser with a fluid pump for dispensing fluid on movement of an actuator, and an air pump for delivering a stream of air through at least one sound generator on movement of the actuator. The sound generator produces at least two sounds as the actuator is moved from a first position to a second position, with each sound produced in a different time period during a cycle of operation, or differing from the other sound in respect of one or more detectable sound characteristics, such as duration, frequency, temporal alignment, amplitude, and/or timbre. The time period of each sound is a function of the relative location of the actuator between the first and second positions.

A station for covering a bread roll half of a bread roll with a sauce in a preparation line of a fast food restaurant, comprising: a table by which a user standing at a front side can cover a bread roll half with sauce, a container comprising the sauce and arranged over the table at a working distance from the front side and from which an outlet nozzle oriented towards the table protrudes at a vertical distance from the table, so that the bread roll half which is to be covered with sauce can be placed on the table below the outlet nozzle, and a pressure actuator that can be actuated by the user and which is designed to dispense the sauce from the container onto the bread roll half when actuated by the user.

The present application relates to a device for dispensing a determined weight of a cosmetic product into a receptacle from a reservoir, the device comprising at least one electromechanical member capable of moving an amount of cosmetic product from said reservoir installed in the device to a dispensing zone of said device where said amount of product may be transferred through a nozzle into the interior of the receptacle received in said dispensing zone, the device comprising a controller configured to deliver a control signal to the electromechanical member according to an error with respect to a setpoint corresponding to the determined weight of cosmetic product to be delivered, said error being determined on the basis of a weighing datum obtained by at least one weighing cell for the reservoir installed in the receiving zone, the device being characterized in that the controller is a reinforcement-learning controller.
