Various embodiments are described herein for a device for storing first and second ingredient materials, mixing the ingredient materials to form an adhesive material and dispensing the adhesive material. Various embodiments are also described herein for a method of making the device and a method of using the device.

Systems for a plastic pump/actuator capable of containing and pumping organic solvents and lubricants and having a more desirable lubricity within the system. The system has at least two cylinders, with plungers therein, oppositely disposed from each other and configured to operably connect to a pump.

Mixing device (1) and fluid mixing method, by means of successive transfers between syringes. The mixing method comprises placing a pair of syringes (2, 3) in the mixing device (1), adjusting a variable fixing element adaptable to the pair of syringes (2, 3) and selecting and running a mixing programme, being the mixing force, the speed and the range and the number of transfers adjustable. The mixing device comprises a mobile carriage (7) longitudinally movable and fixing elements (8, 9) with an adjustable distance between them. The invention allows for the mixing or emulsifying of blood fluids with different viscosity, particularly a protein gel and a platelet-rich plasma, for the preparation of dermatological formulations, in a versatile, hygienic and effective manner.

The invention provides a system for the preshearing based control of the flow and deformation behavior, i.e., the setting kinetics, and the time dependent shear viscosity, elasticity of aqueous cementitious suspensions that can be used for bone repair and regeneration. The dynamic cement microstructure is tailored to the demands of the surgical tasks (faster/slower setting) or additive manufacturing tasks (lower/higher viscosity) by application of various preshearing conditions. Since the relationships between the preshearing and pressurization conditions and the setting kinetics and the time dependent changes in elasticity and viscosity are complex, a priori characterization of viscoelastic properties using the advanced rheological characterization technique of small-amplitude oscillatory rheometry is needed to enable such tailoring. The preshearing system is intended to give control on the injectability and setting time of any calcium phosphate cement formulation to the surgeon during an orthopedic surgery where a batch of bone cement is processed. Other possible utilizations of the system include controlling the setting kinetics, shear viscosity and facilitating the resultant flow stability of cementitious ceramic suspensions processed in direct ink writing assemblies for additive manufacturing of cement constructs, in injection systems for oil wells, restoration and fracking.

A flow-through cavitation device having an elongated housing with an inlet and an outlet. An inner annular body and an outer annular body are concentrically and nestingly disposed in the elongated housing. The outer annular body is fixed relative to the housing and the inner annular body is rotatable about a longitudinal axis of the housing. Each annular body has a plurality of channels that pass therethrough. Rotation of the inner body relative to the outer body provides for selective alignment or misalignment of the plurality of channels to control fluid flow from the inlet to the outlet. The device may have a plurality of pairs of inner and outer annular bodies as described.

A variety of applications exploiting the Shapeless language where the geometry of letters is immaterial; their size and proximity deliver their message. These applications span rescue effort, industrial practice, painting, food preparation, authentication of documents, etc. Shapeless language is computer readable and very robust.
