Inventor: PELLEGRINO ERNEST N
IPC: G01N1/00
Filed: 1987-05-18
Abstract: A rotary shear valve comprising two stators and a rotor is filled with specimen in a first rotary position. Movement of the rotor to a second rotary position divides the specimen into aliquots, one or more of which are dispensed in the second rotary position. A cleaning cycle is provided in which cleaning solution is introduced, with the rotor in a third rotary position, into circumferentially-extending arced grooves formed in the rotor faces, which contacts in the third rotary position those portions of the rotor faces likely to contain smeared specimen. The requirement for disassembly for cleaning is thereby reduced.

Abstract: A contour compensating circuit is disclosed for compensating a video signal (a) in such a manner as to obtain contour portions which are not overly stressed. The compensating operation is performed by obtaining a full-wave rectified signal (c) of the primary differentiated signal of a video signaland the postitive- and negative- phase signals of a secondary differentiated signal thereof. A secondary pseudo-differentiated signal (i), formed with a narrow pre- and post- overshooting width range, is formed from the signals obtained by selecting a first higher level signal (f) between the full-wave rectified signal and one of the positive-phase signal and the half-wave signal thereof identical in polarity with the full-wave signal, selecting a second higher level signal(h) between the full-wave rectified signal and one of the negative-phase signal and the half-wave signal thereof identical in polarity with the full-wave signal and comparing (15) the first and second higher level signals. The resulting signal (i) is superposed (16) on the video signal (a).

Abstract: A foldable playyard (10) comprises upper and lower frame assemblies. The lower frame assembly comprises a unitary central hub member, corner leg connecting members (84, 86, 88, 90) preferably in the form of support feet, and hub legs diverging radially outwardly from the hub member. The upper frame assembly includes corner rail connecting members (92, 94, 96, 98) and pairs of in-line side rails which are pivotably coupled at their outer ends to adjacent corner rail connecting members and at their inner ends to a medial rail connecting member. Corner legs interconnect and are freely coupled to the upper and lower frame assemblies. In one embodiment, the medial rail connecting member houses a hand releasable latch mechanism. In other embodiments, a hand releasable latch mechanism is rotatable with the side rails between latched and released positions. When the playyard is erected, the hub legs and side rails maintain the corner legs upstanding in a spread configuration. When the hub legs and side rails are collapsed, they draw the corner legs towards the hub member and into a compact configuration. For safety purposes, the rail pairs cannot be collapsed unless the latch mechanism is released. A discrete foldable floor having rigid sections is foldable into a box-shape for carrying the collapsed playyard.

Abstract: Apparatus for projecting multiple images from a pair of reticles (117) onto a photo-sensitive coated substrate (1) to produce large scale electronic devices, comprises a pair of parallel and proximate optical systems (13,15), which are positioned to project in the z-direction upon a movable stage (11) subject to controlled motion in the x- and y-direct­ions, means for determining the coordinates of motion of the stage (11) relative to images projected from the reticles, means for using the determined positions to establish a stage transfer function for the appar­atus relative to various positions of stage, and means for applying the transfer function to adjust the relative positions of the reticles (117) and substrate (1) for accurate image projection, and for thereafter projecting an image (R1, L1) upon the substrate. The stage (11) is then stepped to a position to permit projection of an abutting image, and the transfer function is used to adjust the relative positions of the reticles (117) and substrate (1) for accurate image projection for projecting the abutting image upon the substrate 91). The steps are repeated until sufficient images have been projected upon the sub­strate to make up one integrated layer of a flat panel display or other large scale electronic device. After treating the photosensitive layer, subsequent layers are produced in a similar manner.

Abstract: The gun comprises a cathode (C), a control grid (G), a first anode (A1) a second anode (A2) and a third anode (A3). Preferably a beam width limiting aperture (BL) is provided in the first anode (A1). In one example the current modulating voltage applied to the grid is 0 to -50V, the voltage applied to the first anode is +5kV, the focus voltage applied to the second anode is +500V, and the EHT voltage applied to the third anode is +25kV. A main focussing lens is formed by the second and third anodes, but the spacing of the first and third anodes is small so that the focussing effect is also substantially dependent on the voltage of the first anode. The field strength between the grid and first anode is high, which combined with the high A1 voltage produces a small crossover.

Abstract: Described is an isoelectric focusing electrophoretic process for the separation and purification of an amphoteric or neutral chemical compound from one or more electrically charged chemical compound(s). Said process is illustrated below at the example of the purification of a protein from contaminating proteins and salts. It may be carried out in an apparatus especially designed therefor, e.g. an apparatus as depicted in Fig. 1. Said apparatus and various modifications thereof are also claimed. The mixture to be separated is present within a hydraulic flow in chamber  8.  Cylinders  5  and  12  contain immobilized pH-gradients or are replaced by amphoteric isoelectric pH-membranes. Each of said pH-gradients and pH-membranes has conductivity and both buffering and titrant capacity in its pH-interval. The extremities of said gradients or pH-membranes forming the ceiling and the floor of chamber  8  have isoelectric points equal to or just higher and just lower than the isoelectric point of the protein of interest which is kept at its isoelectric point in the hydraulic flow and does not enter said pH-gradients and pH-membranes. Contrary thereto the contaminating proteins and salts are driven by an electric field into said pH-gradients or via said pH-gradients or pH-membranes into the electrolyte reservoirs  3  and  14.  The described process has the advantage that the desired compound need not be detected and extracted from any matrix, e.g. from said pH-gradients, and that the recovery and purity of the desired compound is higher.
