Title: Culture and isolation of fetal cells from maternal peripheral blood
Inventor: PAVELKA KAREN
IPC: C12Q1/6806
Filed: 1995-03-29
Abstract: Methods for culturing and isolating fetal cells, e.g., fetal erythroid cells, from a sample of peripheral blood obtained from a pregnant woman are disclosed. Cells from the sample of peripheral blood are cultured in a medium containing a cell growth factor, e.g., an erythroid growth factor, e.g., erythropoietin, to culture fetal cells. Prior to culture, non-nucleated cells can be removed from the sample of peripheral blood and/or fetal cells can be enriched. Metaphase spreads can be prepared from cultured fetal cells. A fetal cell marker or a nucleic acid sequence of interest can be detected in cultured fetal cells. The cultured fetal cells can be used to determine fetal sex and to detect disease-causing mutations and chromosomal abnormalities in a fetus.

Abstract: A quick release clamp(10) for mounting equipment such as a lighting instrument (60) on a structural member such as a pipe (36). The clamp includes aC-shaped body(12) having a jaw portion(16), a back portion(14) and a base portion (18), the jaw and base portions extending from the back portion in spaced opposing disposition. The base portion defines an adjustment aperture (22) that is formed with an internal interrupted tread (24). An elongate tubular coarse adjustment sleeve (26) defines an internal threaded central passage (28) and an external interrupted thread (30) corresponding to the internal interrupted thread of the body. The sleeve is receivable within the adjustment aperture of the body and rotatable about a longitudinal axis of the sleeve into a first position, in which the sleeve is freely movable longitudinally within the adjustment aperture, and a second position, in which the external interrupted thread of the sleeve engages and locks within the internal interrupted thread of the body to prevent longitudinal movement of the sleeve. An elongate fine adjustment bolt (34) is coaxially and threadablyreceived within the sleeve, and is rotatable within the sleeve to project a selected amount through the sleeve towards the jaw and back portions of the body. The base portion of the body also defines a mounting passage (38) which receives the neck (42) of a mounting spigot (40) secured therein. The mounting spigot defines an elongate T-slot (52). A T-stem (58) has a T-shaped head (62) that is slidably insertable into the T-slot of the spigot through an open first end (54) of the T-slot. The head of the T-stem is selectively secured within the T-slot of the spigot by a spring-loaded latch (66) and nut (68) carried on the stem of the T-stem. The lighting instrument is secured to the stem (64) of the T-stem, and may be rapidly connected and detached from the clamps.

IPC: H01L41/12
Filed: 1995-06-02
Abstract: A torque sensor (2) comprises a magnetoelastically active element (4), and a magnetic sensor (6) responsive to the field of the magnetoelastically active portion. The magnetoelastically active portion comprises a ring of material (4) endowed with an effective uniaxial magnetic anisotropy such that the circumferential direction is the easy axis, and magnetically polarized in a substantially circumferential direction. The ring (4) is attached to the torqued member (8), such as a rotating shaft, so that application of a torque to the shaft is transmitted to the ring. A magnetic field vector sensor (6) is mounted in a fixed position relative to the ring (4) and oriented so that it responds maximally only to the field due to the axial magnetization components of the ring (4). The output of the sensor (6) is thus proportional to the change in orientation of the magnetization resulting from torque applied to the shaft (8) and transmitted to the ring (4). The magnetoelastically active portion (4) may include two or more axially distinct, magnetically contiguous, oppositely polarized circumferential regions (104, 105).

Title: Trichromatic sensor
Inventor: BOHM MARKUS
IPC: H01L25/04
Filed: 1995-08-31
Abstract: The invention relates to a photo sensitive electronic component based on amorphous silicon and its alloys, comprising two, in respect to each other antiserially arranged, p-i-n or n-i-p or Schottky-contact structures, in which in each case the active layers are arranged in the normal way in the direction of light incidence, whereby in the area of the first structure in the direction of light incidence, the charge carriers generated by blue light are collected for a first (V1) voltage; and in the area of the second structure in the direction of light incidence, the charge carriers generated by red or green light are collected for a second (V2) or a third (V3) voltage, and whereby at least one of the two intrinsically conducting layers is constructed from two partial layers. The object of creating better spectral selectivity is achieved in that in the partial layer (I) which is in front in the direction of light incidence, a higher product from charge carrier mobility and life-time (µ-tau product); and in the partial layer (II) which is at the rear in the direction of light incidence, a lower product from charge carrier mobility and life-time (µ-tau product) is present, in such a way that the two partial layers (I, II) in the presence of an electrical field, have different collection lengths for the charge carriers so that in the partial layer (I) which is in front in the direction of light incidence, increasingly green light, and in the partial layer (II) which is at the rear in the direction of light incidence, increasingly red light is absorbed.

Title: Method and apparatus for uniformly dispersing articles in a treatment solution
Inventor: JANSSEN ROBERT ALLEN
IPC: B05C3/04
Filed: 1995-11-22
Abstract: An apparatus and method for uniformly contacting an article with a treatment solution. Preferred embodiments are methods of uniformly tinting of contact lenses or uniformly surface modifying contact lenses. The method involves suspending the lens in the treatment solution by application of fluid flow, preferably sinusoidal or pulsed, in a direction opposite the stagnant force (i.e., sum of buoyancy and gravity forces) on the article. The fluid flow prevents the lens from contacting the container structure for periods sufficient to cause non-uniform treatment conditions, while continuously mixing the treatment solution to maintain uniform concentrations throughout.
