Abstract: A device for the targeted, controllable deliver or drawing of a liquid or viscous substance, comprises a reservoir and a plunger that subdivides the reservoir into a storage space for the viscous substance and a pressure space for gas. The storage space for the viscous substance leads to a discharge opening for the viscous substance, and an insert is placed in the pressure space inside the reservoir and contains at least one gas generator cell and a circuit for controlling the running time. The wall of the reservoir is, at least in sections, multilayered and translucent, whereby at least two layers are made of different chemical substances.

Abstract: A brushing device (1) for lubricating and cleaning guide and drive elements has a lubricant dispenser (2), a brush element (4) for applying the lubricant to the machine element, a delivery line device (3) connected to the lubricant dispenser for feeding lubricant to the brush element (4), where the delivery line device (3) is provided with a delivery line path (10) composed of an absorbent pad of a felt-like or fleece-like material.

Abstract: A device for controllably dispensing a liquid or viscous material comprises a chamber which is subdivided by a piston into a pressurized gas chamber and a mass chamber. The container includes electrochemical, tablet-shaped, completely enclosed diffusion electrodes, aqueous electrolytes, a gas development cell containing a counter-electrode, an adjusting rheostat and contacts held by a clamping device in the bottom of the container. A vibration-dampening funnel-shaped container cap encloses the top end of the container and is totally compliant and shock-proof. The piston includes a piston seal which has a sealing lip monolithically connected to the piston with a space for a film of grease. An alternative embodiment has exchangeable electric elements and a refilling device. Other alternative embodiments have a simplified compact design for small sizes or for infusion devices or are associated with piston sensors.
