Title: Method of measuring using a laser
Inventor: PALOMBI VERN
IPC: G01B11/14
Filed: 1990-06-18
Abstract: ABSTRACT OF THE DISCLOSURE A method of measuring using a laser consisting of the following described steps.   Firstly,  establishing a first reference point and a second reference point spaced a known distance apart,  thereby providing a scale for measurement. Secondly, establishing a target thereby denoting the distance to be measured.  Thirdly, projecting a laser light beam from the first reference point onto the target and measuring a first resultant angle relative to a horizontal plane, and a second  resultant  angle  relative  to  a  vertical  plane. Fourthly,  projecting  a  laser  light  beam  from  the  second reference  point  onto  the  target  and  measuring  a  first resultant angle relative to a horizontal plane, and a second resultant angle relative to a vertical plane.  Fifthly, using the  scale  provided  by  the  known  distance  between  the reference  points and  the  measured angles  as  a basis  for trigonometric  calculation  of  the  horizontal  and  vertical distance to the target.

Title: Universal assembly for top and bottom latches, in vertical-rod, exit devices,and top and bottom latches for such devices
Inventor: COHRS RICHARD B
IPC: E05C9/16
Filed: 1990-06-21
Abstract: The universal assembly comprises components and parts interchangeable between, for being common to, a top latch and a bottom latch in vertical-rod exit devices.  Simply by adding a few discrete parts to the assembly, the same becomes, selectively, a top latch or a bottom latch.  The top latch, and the bottom latch, comprise the universal assembly to which the respective, discrete parts have been added.  The assembly, and the latches have a rotatable input member which must be rotated to enable retraction of a latch bolt, and a limb operative to block retraction of a latch bolt if the input member is not rotated.

Title: Removal of molybdenum from uranium-bearing solutions
Inventor: LAM EDMOND K
IPC: C22B60/02
Filed: 1990-09-13
Abstract: A process for removing molybdenum from uranium bearing  solutions  reduces molybdenum contamination  of uranium product.  The process employs solvent extraction techniques to remove molybdenum by using a molybdenum-selective extraction reagent of the chelating hydroxy-oxime type.  The molybdenum-loaded extractant is stripped with dilute alkali for reuse.         Where the uranium bearing solution originates from a solvent extraction process, a pretreatment stage is applied using an agent to remove entrained uranium extractant.

Title: Pressure monitoring device for self-contained breathing apparatus
Inventor: GRAY ROBERT E
IPC: A62B9/00
Filed: 1990-11-13
Abstract: ABSTRACT OF THE DISCLOSURE      There  is  disclosed  a  pressure  monitoring  device  for self-contained breathing apparatus including visual indicators disposed in the field of view from the headpiece to monitor when predetermined  pressure  levels  are  reached  in the tank which supplies  gas  to that  headpiece.

Title: Pam signal modulation with mappings to improve utilization of available transmission capacity
Inventor: KNAUER SCOTT C
IPC: H04N7/00
Filed: 1991-03-07
Abstract: PAM SIGNAL MODULATION WITH MAPPINGS TO IMPROVE UTILIZATION OF AVAILABLE T`RANSMISSION CAPACITY Abstract A high definition television system that is characterized by low transmission bandwidth is achieved by removing redundancies in the signal, encoding the remaining signals, and transmitting the encoded signal in a manner that is most compatible with the applicable standards. The dynamic range of the encoded signal is reduced by combining groups of adjacent samples that are smaller than a "floor" threshold to form larger samples, and by splitting samples that are larger than a "ceiling" threshold to form a plurality of smaller samples. Encoding of the combined samples is carried out in a conforming manner to minimize deleterious effects of transmission noise.

Title: Magnetic recording and reproducing device
Inventor: KONDO YOSHIO
IPC: G11B15/30
Filed: 1991-03-27
Abstract: ABSTRACT OF THE DISCLOSURE     A video camera with a tape deck mechanism in which the rotary head drum and tape loading device is inserted completely into a dead space in the tape cassette, the lid of the cassette is then closed and the recording/playback operation performed.  The tape deck mechanism is reduced in size by having multiple chassis that slide into and fold over each other with the tape cassette contained therein.  The tape deck mechanism operates in conjunction with a special tape cassette to increase the available dead space by moving the cassette tape reels apart when the head drum chassis slides into another chassis holding the cassette.  The lid of the cassette is opened with a mechanism that does require pressure against the cassette to overcome the lid closing spring of the cassette.  The tape deck mechanism can be arranged with the known video camera electronics and optics in various configurations to provide a compact video camera.

Patent CA-2045851-A1 (CA)
Inventor: NEAL ARCHIE E
IPC: A01G23/02
Filed: 1991-06-27
Abstract: Disclosed is a seedling planter, particularly useful far tree seedlings, which has a main frame adapted to be hitched behind a pulling vehicle. The main frame is supported above the ground by the hitch and support wheels located near the rear of the planter. The support wheels are preferably mounted on a carriage which is pivotable relative to the frame thereby allowing the force exerted by a set of intermediate packing wheels to be varied. The seedling plantar uses a novel planting assembly which incorporates two primary structural members; a first planting assembly piece or link which is connected to the frame, and a planting arm which is pivotally connected to the first piece. The first piece is movable to vary the height of the pivot axis about which the planting arm rotates. The planting assembly also preferably includes a soil height level detection subsystem. The detected soil height level is used by a height control subsystem to automatically control the downward extension of the first planting assembly piece. The planting arm is thus positioned at a desired predetermined height above the soil as it is rotated into the ground to provide consistent planting depth. The planting arm mounts a seedling holder which clamps the seedlings along the rear edge of the planting arm. The seedling holder has jaws which are opened by interaction with a cam. Extension of the planting arm downwardly causes the seedling to be automatically grasped by the jaws. A  lever arm actuator automatically opens the seedling holder when the planting arm is extended to thereby release the seedling into a short furrow formed in the soil by the extended planting arm. Also described are novel methods.
