Further disclosed are rapidly disintegrating tablets for use in the preparation of compositions for treating keratinous fibers.

A sewage treatment chlorinator for use at a site not connected to a municipal sewer system and system and method for use of the same are disclosed. In one embodiment of the sewage treatment chlorinator, a housing includes an external conduit coupled in a t-connection to a flow tube. An inner canister is sized to be selectively inserted and removed from the external conduit and includes a perforated end cap having a flow deck sized to suspend a chlorine tablet within a contact chamber of the flow tube. The flow tube receives effluent form an aerobic tank and discharge treated effluent to a post-treatment tank. At least a portion of the discharge from the flow tube is gravity-based discharge into the post-treatment tank.

Method of robot control is disclosed that includes the steps of: providing a user interface for introducing data indicative of a drug to be subjected to a reconstitution process; accessing an internal data base for outputting, for a selected drug, a list of primitive movements P1, P2, . . . Pi, . . . Pn to be used in the reconstructing process; operating the robot for executing sequentially the primitives and moving a container according to the instructions of the primitives; measuring, during the movement of the container under robot action, physical positions in the space and dynamic parameters of the container creating a list of registered data; comparing the measured positions in the space and the dynamic parameter with the corresponding ones of the primitive movements for selecting a list of eligible primitives if a sufficient approximation level is reached; elaborating selected eligible primitives together to generate instructions for the robot allowing a complex movement encompassing the simple movements; and using the robot for shaking the container according to the complex movement.

Diffusion device intended to accept a flanged capsule containing a product that is to be diffused comprising a body, a bearing surface borne by the body directly or indirectly, an outlet passage for letting product out of the capsule, a knob mounted with the ability to rotate on the body, the knob comprising an upper part projecting axially beyond the bearing surface, the knob and the bearing surface being mounted with the capacity for helicoidal rotation relative to one another, a closure movement of the knob being able to bring the lower face of a rim of the device to face the bearing surface, the closure movement of the knob comprising a rotational movement of the knob with respect to the body causing a helicoidal movement between the knob and the bearing surface that is able to bring a lower face of the rim and the bearing surface closer together.

The invention discloses a method for predicting the solubility of at least one species at a specified pH value in an aqueous buffer comprising at least one weak acid species and/or at least one weak base species. The method comprises the steps of: a) selecting a start composition of the buffer, giving a start value for the total solute concentration; b) calculating the concentrations of all ionic species present in the buffer at the specified pH value from the total composition of the buffer and available dissociation constants; c) calculating the solubility limits of each combination of ionic species present in the buffer from available solubility products, taking the concentrations calculated in step a) into account; d) comparing the concentrations of all ionic species calculated in step a) with the solubility limits calculated in step b) and determining if any solubility limit is exceeded; e) if no solubility limit is exceeded, increasing the total solute concentration of the buffer or, if at least one solubility limit is exceeded, decreasing the total solute concentration of the buffer, and; f) repeating steps b)-e) until a predetermined convergence criteria is met.

A medicament preparation system, according to an embodiment, includes a water purification module and a medicament proportioning module. The system is configured to allow convenient and safe use in a home environment or a critical care environment as well as others affording safety, reliability, and a compact form factor.

An apparatus and method for manufacturing an electricity storage material are provided which allow easily measuring the dissolution rate to solubility of a solution of a powder thickener dissolved in a liquid solvent. An apparatus for manufacturing an electricity storage material includes: a dissolving device that dissolves in a liquid solvent a thickener as powder that is ionized when dissolved; and a dissolution-rate-to-solubility determining device that measures conductivity of the solution produced by the dissolving device and determines a dissolution rate to solubility of the solution based on the measured conductivity. The dissolution rate to solubility can thus be determined without the need to stop the dissolving device during dissolution of the thickener in the liquid solvent. This can significantly improve production efficiency. Since excessive operation of the dissolving device can be prevented, energy saving can be achieved.

A system and process are disclosed for dissolution of solids and “difficult-to-dissolve” solids. A solid sample may be ablated in an ablation device to generate nanoscale particles. Nanoparticles may then swept into a coupled plasma device operating at atmospheric pressure where the solid nanoparticles are atomized. The plasma exhaust may be delivered directly into an aqueous fluid to form a solution containing the atomized and dissolved solids. The composition of the resulting solution reflects the composition of the original solid sample.
