Abstract: A new cultivar of Erysimum plant named ‘Cdcery1’ that is characterized by its foliage that is silverly dark green in color, its flowers that are vivid red in color with minimal fading, its flowers and leaves that are large in size, its strong and upright stems, its low maintenance, compact plant habit, and its drought resistance.

Abstract: A hydraulic circuit includes a pump in fluid communication with a reservoir containing a liquid to be pumped. The pump includes an inlet and an outlet. The hydraulic circuit also includes a venturi pump in fluid communication with the reservoir and with the outlet of the pump, and an injection valve including a cooling feature. The injection valve is in fluid communication with the outlet of the pump, and is configured to dispense liquid supplied to the injection valve by the pump. The cooling feature is in fluid communication with the venturi pump. The pump is configured to produce a first flow of liquid, and the hydraulic circuit is configured to supply a first portion of the first flow of liquid to the injection valve for dispensing by the injection valve and a second portion of the first flow of liquid to the venturi pump.

Abstract: The peristaltic pump is provided with a two-piece housing (2, 3), in which a conveying member (1) as well as a pump tubing section (6) squeezable by the conveying member is received. For fixing the pump tubing section (6) in the housing (2, 3), a tubing holder (4) is provided. Further provided is a connecting element (5) provided with duct shaped connecting sockets (14a, 14b) for connecting tubing sections (15a, 15b). For connecting the pump tubing section (6) to the tubing holder (4), the two ends of the particular pump tubing section (6) are fixed in receptacles (10a, 10b) of the tubing holder (4), which positively enclose the outside of the pump tubing section (6). The connecting element (5) is fixed to the tubing holder (4) by means of a snap-on connection. Thereby, the connecting sockets (14a, 14b) thereof are sealingly connected to the particular pump tubing section (6).

Abstract: Valveless piston pumps are disclosed that are magnetically driven, thereby eliminating a troublesome dynamic seal used on conventional valveless piston pumps. An exemplary embodiment includes a housing defining a bore having a bore axis. A piston is situated in the bore so as to be movable in the bore in a reciprocating manner along the bore axis and in a rotational manner about the bore axis. A magnet is situated in the bore and is coupled to the piston. The magnet is engageable magnetically with a magnet-driving device configured to cause the magnet, and thus the piston, to move in the reciprocating manner and in the rotational manner. An exemplary magnet-driving device is a stator assembly.

Abstract: An alignment apparatus for optical components includes chemically co-etched parts which may be assembled with high tolerances and in a repeatable manner. The resulting construction, together with a translatable stage and/or a micrometer, allows for rapid and extremely precise alignment of the mounted optics.

Abstract: A continuous process for the separation of small particles from larger particles in a biological preparation passes a liquid stream of the preparation through a first filter or screen, which retains larger particles, passing smaller particles in the liquid. The large particles have retained on their surfaces wetting water, in which are entrained some of the small particles. The large particles are directed to a liquid having a concentration of smaller particles lower than the concentration of smaller particles in the wetting water, and mixed therein. The smaller particles separate from the larger particles in the mixed suspension, which is then directed to a second filter or screen, for further separation. The smaller particle/liquid stream may be recycled to the biological preparation stage, the liquid suspension for the large particles, or to a separator means where the smaller particles are separated off from the liquid stream.
