A liquid reservoir, particularly for use in an hydraulic system. The reservoir includes a container and a cover cap, and it is intended for containing an hydraulic pressure medium. A pressure equalization component is provided within the container for compensating for pressure differences between the interior of the container and the surrounding atmosphere, and a level compensation component is provided for compensating for changes in the volume of the pressure medium. The pressure equalization ...

Provided is a liquid cosmetic characterized by comprising 5 to 25% by weight of a pearl pigment containing at least mica, mica titan or a surface-treated substance thereof and 0.2 to 2.0% by weight of an anionic high molecular compound as a structural viscosity-providing agent, wherein the non-Newtonian viscosity index (n) falls in a range of 0.16.ltoreq.n.ltoreq.0.28, and the viscosity satisfies the following condition (A):

A non-contacting seal which includes a stationary tooth that radially overlaps a tooth on a rotatable shaft, with the sealing action resulting from controlled clearance both radially between stationary tooth and the shaft, and axially between the stationary tooth and the shaft. The seal may also be in the form of a stationary tooth that is approximately in the same radial plane as a tooth on a rotatable shaft, with the sealing action resulting from both a controlled clearance gap between the two...

A liquid container is provided, which comprises a bag-forming flexible container body, a pouring outlet provided to communicate with an inside of the container body, and a support member provided in the container body for inhibiting deformation of the container body occurring near the pouring outlet when the contained liquid is sucked, in which the support members is a member reinforcing the container body with a form like a funnel narrowed at the pouring outlet. If the funnel-like reinforcing p...

There is provided a liquid container capable of transferring liquids germ free in a simple manner within a short period of time and with inconsiderable solution remaining after transfer. The liquid container includes a vessel main body 1, a mouth portion 11 of which is closed by an easily breakable closing member 12, and a hollow needle member 2 crowned pivotably on the mouth portion 11 of the container main body 1. The closing member 12 is provided with a flat knob portion 121. A knob-containin...

A liquid container comprising: a shaft; a fixed cylinder including a discharge valve and provided on an upper end of the shaft; a liquid supply means provided on an upper end of said fixed cylinder; a liquid receiving means provided in the shaft and slidable with respect to the shaft; a movable cylinder including a suction valve, said movable cylinder being fitted in an upper end of the liquid receiving means and slidable with respect to said fixed cylinder; springs for rearwardly biasing the mo...

A sample solution is sent into a concentration column through a three-way joint and a three-way switching valve to trap and concentrate the sample components on the concentration column, followed by injecting the sample solution into an injector by operating a first dilution solvent pump. When a large volume of the sample solution is to be sent or when the sample solution has a high solvent strength, trapping and concentration on the concentration column may be facilitated by replacing the sampl...

Compounds of the formula ##STR1## wherein, inter alia, R.sup.1 is hydrogen or straight-chain alkyl; R.sup.2 is --CN, --R, --COR, --COOR; R is alkyl; A is a group with 1 to 4 six-membered rings, these rings being linked directly with one another and with ring B in each case via a single covalent bond or being linked at one or two positions also via ester or ether groups; the six-membered rings in A and ring B each are 1,4-phenylene or trans-1,4-cyclohexylene or one of these rings also is trans-2,...

A liquid detergent based on nonionic and anionic surfactants, and optionally particulate builder materials, contains a non-surfactant component which increases the wash efficiency, comprising the combination of low-polarity and mid- to high-polarity organic liquids. The low-polarity liquids are hydrocarbons, while the mid- to high-polarity liquids are esters, ethers, ketones or alcohols. The detergents have a satisfactory viscosity behavior, good miscibility with water and good wash efficiency.

A liquid is dosed by an apparatus that has a housing formed with an inlet connected to a supply of the liquid, an outlet, a filling chamber, and a bypass chamber having an outlet side from which the outlet opens and an inlet side connected to the inlet. A pumping piston subdivides the filling chamber into an inlet compartment into which the inlet opens and an outlet compartment. A valve element in the housing can move between a filling position blocking the outlet and connecting the inlet throug...
