Abstract: A latch is provided for use in window constructions, particularly vertically and horizontally sliding window constructions.  The latch is generally mounted internally in a sash frame so that its latch bolt protrudes from the sash to engage a guide slot in the main frame jamb or header.  The latch includes a thin rectangular base plate having upstanding bosses on its opposing ends which are pierced by vertical bores that pass through the base plate.  The latch bolt is of substantially the same width as the base plate and slides over it.  The bolt includes two ovate openings spaced to receive the upstanding bosses on the base plate, each opening having a first lower region sized to slidably accomodate a boss and a second wider upper region sized to slidably accomodate the head of a screw fastener.  Two screw fasteners driven respectively through the vertical bores in the bosses on the ends of the base plate affix the latch to a window sash and secure the bolt to the base plate.  A coil spring biases the bolt to its extended position.  The base plate further includes two opposing short vertical walls with inturned wedge-shaped protrusions along their top edges which slidably grip longitudinal rail regions on opposite side of the middle of the latch bolt to maintain the latch in an assembled condition before it is attached to the sash of a window.  A finger pull is also provided to facilitate manipulation of the latch.

Inventor: BUTTKE ROBERT D
IPC: C10G49/26
Filed: 1990-10-29
Abstract: The inventive procedure more accurately maintains an inventory of a catalyst in an ebullated bed of a reactor in an oil refinery, especially a  resid hydrotreating unit.  The ebullated catalyst bed has therein three phases (catalyst, oil, gas).  A first density measurement is made of the two-phase mixture in a freeboard zone i.e. of gas and oil in a catalyst free area above the ebullated catalyst.  A second density measurement is made in the catalyst bed where all three phases are present.  Density measurements are used, along with predetermined values for vapor, liquid, and soaked particle densities and corrections for gamma-ray absorption coefficients, in order to calculate the catalyst particle holdup in the vessel.  From this, the amount of catalyst actually in the reactor can be calculated.  Once this amount is known, fresh catalyst may be added to or spent catalyst may be removed from the reactor in order to maintain a fixed catalyst inventory within the catalyst bed.

Title: High definition zero mark for optical encoder
Inventor: HOECH ROBERT W
IPC: G01D5/36
Filed: 1991-03-20
Abstract: Abstract of the Disclosure An incremental position encoder makes use of a first and second track of non-identical non-complementary aperiodic patterns to generate a zero mark.  A mask with the identical pattern to the first track and a mask with the complementary pattern to the second track correlate with the patterns on the first and second track when the encoder is in zero position.  Light transmitted by the masks produce electrical signals that are compared to create the zero mark.  An iterative approach improves the discrimination of an initially selected track pattern for its particular application based on developed criteria for good noise immunity and resolution.  The size of the reference track with respect to the increment track and the placement of each mask on the stator and rotor are optimized.  A system for improving noise immunity by biasing the signal from each photodetector is also shown.
