摘要： The valve for controlling the flow of a fluid, particularly very small flows, comprising a block having at least one smooth face and at least two ducts extending through the block and terminating in the smooth face in an orifice. A slide is guided for movement substantially parallel to the smooth face and is moved, e.g. by means of a screw or pneumatically. A valve element movable with the slide is urged into sliding contact with the smooth face and a recess in the valve element is dimensioned to overlie and connect at least two of the orifices in at least one position of the slide.

摘要： A volumetric metering pump for accurately dosing small quantities of liquid, in which two interconnected identical parttoroidal pistons are arranged in separate cylinders. Small pulse jerks are simultaneously applied to each piston by a rockable member connected to a step-by-step electric motor, so that one piston draws liquid into its cylinder while the other piston expels liquid from its cylinder. This pistons are thus caused to move along arcuate strokes in the direction of their respective axes. A slide valve is provided firstly to direct liquid from an inlet duct to one cylinder and to an outlet duct from the other cylinder. At the end of each stroke this situation is reversed.
摘要翻译：一种用于精确计量少量液体的体积计量泵，其中两个相互连接的相同的部件环形活塞布置在独立的气缸中。通过连接到逐步电动机的可摆动构件将小脉冲脉冲同时施加到每个活塞，使得一个活塞将液体吸入其气缸中，而另一个活塞从其气缸排出液体。因此，该活塞沿着它们各自轴线的方向沿弓形冲程移动。首先提供滑阀以将液体从入口管道引导到一个气缸，并将另一个气缸的出口导管引导到出口管道。在每次冲程结束时，这种情况相反。

摘要： A gear pump is constructed entirely of ceramic material, and includes a body having two side plates and an intermediate member, the latter being formed with two communicating part cylindrical seats in which meshing gear wheels can rotate without bearings. A drive shaft engages in a recess in one of the gear wheels, the recess being of a non-circular cross-section and the shaft engaging therein with a clearance.

摘要： The specification describes a volumetric metering pump for accurately dosing very small quantities of liquid, in which two pistons are arranged to extend in opposite directions, and are interconnected by a crossmember. Small pulse jerks are simultaneously applied to each piston, so that one piston draws liquid into its cylinder and the other expels liquid from its cylinder. A slide valve is provided firstly to direct liquid from an inlet duct to one cylinder and to an outlet duct from the other cylinder. At the end of the stroke this situation is reversed.

摘要： 1283907 Semi-rotary pumps RHONEPOULENC S A 22 Oct 1970 [23 Oct 1969] 50285/70 Heading F1F An oscillatory-piston semi-rotary volumetric metering pump for accurately dosing very small quantities of liquid i. e. providing a regular delivery of pulsed liquid with very great precision for use in laboratory work such as chromatography, comprises two arcuate inter-connected pistons 3, 4 movable in a series of pulsed jerks in two separate correspondingly arcuate cylinders 5, 6 by a rockable arm 7 fast on the shaft 8 of a mechanical impulse generator such as a reversible "step-by-step" electric motor 1 rotating through a specific angle at each impulse supplied by an electronic device of known type (not shown), the arm 7 moving through a sector of a circle whose amplitude is limited by two abutments 19, 20 each provided with a limit micro-switch 10, 11 actuation of each of which, by striking engagement of the rocking arm 7, reverses the rotation of the step-by-step motor whereby the arm 7 is oscillated between the abutments to create the pumping action, a distributing slide valve 50 selectively and alternatively acting as a suction and delivery valve via ducts 12, 13 connected between the valve 50 and the two separate cylinders 5, 6, the slide valve 50 being controlled by a pair of opposed solenoids 29, 30 alternatively energised and de-energised by a control switch 69 which simultaneously reverses the electric motor drive in the interval of time between two consecutive pulses as the arm 7 alternatively strikes the abutment limit switches 10, 11 which operate the electrical control switching arrangement 69. The pump may alternatively be controlled by a motor driving a ratchet wheel device for generating and regulating mechanical impulses to the arm 7. A mechanical, electro-mechanical or electronic speed varying device may be provided for adjusting the time between successive pulses for readily adjusting a dose to a desired value and for covering a wide range of doses. The pump cylinders 5, 6 may, as shown, form parts of the same circle, or, the pump cylinder's partcircular axes may be parallel and coaxial to one another.

摘要： 833,058. Measuring specific gravity. SOC. DES USINES CHIMIQUES RHONEPOULENC. June 24, 1957 [June 29, 1956], No. 19861/57. Class 97(3) A pair of closed vessels 24, 25 are provided with gas inlet pipes 27, 28 through which gas may be bubbled through a reference liquid contained in the vessels 24, 25, the gas streams then being bubbled through the liquid under investigation in the vessel 20 from pipes 29, 30 extending to different depths. A differential pressure gauge not shown, indicates the pressure difference between the pipes 27, 28. This is a measure of the density of the liquid in the vessel 20. It is shown that if the depths of the liquid in the vessels 24, 25 and the depths to which the pipes 27, 28, 29, 30 extend are appropriately chosen the density is measured as reduced to a reference temperature and corrected for changes due to changes of temperature. The vessel 20 has liquid inlet and outlet 21, 22 and a gas outlet 23. The vessels 24, 25 are contained in the liquid in the vessel 20 to maintain uniform temperature.
