A brush seal includes a retainer and a multiplicity of single bristles each bristle having a fixed end and a free sealing end, the fixed ends being individually attached in a continuous arrangement at the same angle to the retainer, the bristles having a uniform pack density throughout the extent of the bristles from the fixed to the sealing end.

A blood analyzer is provided with means to automatically pierce the sealed closure of a vacuum container or to aspirate through an aspirator tip blood samples to be analyzed. The samples are drawn serially through a repositionable valve structure, preferably of rotary form, and having three members in layers with aligned ports in one position to receive the blood that is drawn through the valve by a syringe type aspirator. Another position of the valve connects diluent supplies providing measured amounts of diluent to wash out the bores of the middle member of the valve containing amounts of blood measured by the size of the bores. In the case of the red blood cell measurement, where the bore is extremely small, a larger by-pass port is provided in parallel with the sample containing bore to allow more rapid flow simultaneously through both. Blood analysis is performed by separate conventional cell counter arrangements for each of the red and white counts. A novel configuration involves a bore through a block generally tangential to a bore which engages a cylindrical chamber in the sidewall of which is a jewel orifice. A foil electrode is used in the tangential passage and a larger tapered electrode with the smaller end near the orifice in the cylindrical output chamber. A discontinuity in the form of an air bubble in a passage feeding the counter apparatus enables the position of the bubble to be sensed at one place to turn on the counter and in another place in the passage to turn off the counter. The three-layer valve structure has various special indexing features and cleaning features, and the intake devices have features associated with cleaning as well.

A direct replacement unit for an elevator touch button of the type which uses a voltage dropping gas tube. The replacement unit includes a series circuit, containing a relay coil, a zener diode, an indicator lamp, and a parallel circuit. The parallel circuit includes a normally open contact switch controlled by the relay coil and a mechanical call button.

Apparatus for automatically actuating manually operable selector elements, such as the type which normally are found on a manually operable postage meter. A carriage is provided and is movable between an initial, start position and an end position. Plural actuator elements are coupled to and movable with the carriage. These actuator elements are positioned in operable relation with the selector elements and are selectively energized while the carriage moves between its start and end positions to correspondingly activate the selector elements. When used in the environment of a postage meter, the selective energization of the actuator elements thereby conditions the postage meter to provide a corresponding indication of postage. Reset apparatus resets the carriage following the selective energization of the actuator elements. With minor changes in the structure of the actuator elements, the automatic actuator can be used in conjunction with, for example, postage meters of the type having movable levers selectively positioned to establish corresponding monetary units of postage, or an array of columns of depressible keys, each key corresponding to any one of the possible monetary units of postage.
