Title: Mirror telescope
IPC: G02B23/02
Filed: 1986-10-23
Abstract: A reflecting telescope according to the invention includes a tube having an inlet and a primary mirror end. A plurality of mirror segments cooperate to form a single mirror of a single paraboloid-shaped surface by grinding the mirror segments all together in a single grinding process. This mirror is then positioned at the primary mirror end of the tube. Each of the plurality of mirror segments has a circular disk shape and is arranged in one of circular tracks, each circular track being defined by an inner circle and an outer circle with each inner and outer circle being concentric to the tube central axis. The areas free of mirror segments lie between the mirror segments of circular disk shape and an innermost area free of mirror segments lies within an innermost circular track. Bearings are positioned about each of the mirror segments at the areas free of mirror segments for adjustment of the mirror segments. A system of mounting bars is positioned and connected to the primary mirror end at the areas free of mirror segments, such that light entering the inlet end causes shadows to be cast by the system of mounting bars on the areas free of mirror segments. A plurality of observation cages may be positioned in the innermost area free of segments posed to be positionable between the mirror end and the inlet to provide different modes of observation. A deviation mirror may be provided for reflecting light which has been directed towards the observation cages.

Title: Megakaryocyte stimulatory factor
IPC: C07K14/52
Filed: 1987-09-15
Abstract: A megakaryocyte stimulatory factor (MSF), purified to homogeneity, is an acidic protein (pI = 5.1) with an Mr 15,000 which stimulates PF4-like protein synthesis in rat promegakaryoblast cells by as much as 7-fold, and exhibits half-maximal activity at a concentration of 0.8 pM. MSF exhibits no biologic activity corresponding to other known hemopoietic growth factors, and appears to be specific for the megakaryocyte lineage. In the given examples, MSF was purified to homogeneity (as judged by SDS-PAGE and isoelectric focusing in the presence of 9.2 M urea) from serum-free conditioned medium obtained from cultured human embryonic kidney (HEK) cells, and to near homogeneity from thrombocytopenic plasma. The MSF is isolated by precipitating the MSF with ammonium sulfate at 80% saturation, removing insoluble, non-MSF material and applying the soluble protein to a WGA-Sepharose column, eluting the MSF protein with chitin oligosaccharides, applying the concentrated eluant containing MSF activity to a Biogel P200 column, and chromatographing the eluted MSF fractions on a TSK-G3000 HPLC size exclusion column.

fined uniquely by an address word having an X 
component and a Y component, which memory locations 
correspond respectively to grid points in a rectan­
gular array at a pitch dX in the X direction and a 
pitch dY in the Y direction, is loaded with data 
values Q. In a first operating cycle, a first 
address word defining a memory location corre­
sponding to a first grid point is generated. In a 
second cycle, a first value of Q as a function of X 
and Y is computed, and concurrently a second ad­
dress word defining a memory location corresponding 
to a second grid point is generated. In a third 
cycle, the first value of Q is compared with a 
previous value of Q for the first grid point, and 
concurrently a third address word defining a memory 
location corresponding to a third grid point is 
generated and a second value of Q is computed. In 
a fourth cycle, the first value of Q is loaded into 
the memory location corresponding to the first grid 
point if that first value of Q bears a predetermined 
relationship to the previous value of Q.
