Title: Target and control system for positioning an automatically guided vehicle
Inventor: HAMMILL HARRY B III
IPC: G05D1/02
Filed: 1986-10-17
Granted: 1990-12-04
Abstract: Abstract of the Disclosure Target and Control System for Positioning an Automatically Guided Vehicle A target member mounted on a stationary object, such as a pallet, includes at least three reflector elements.  An identifying means, such as a high intensity light source, and an imaging sensor are carried by another, movable object, such as a forklift truck.  The reflector elements are so configured as to form images of the identifying means with said images defining a plane oriented other than normal to align from the identifying means to that plane, the images also defining a circle that does not include the identifying means.  The target member may be in the form of a vertically oriented planar support member on which are mounted a pair of convex mirrors and a concave mirror.  The images of the identifying means in the mirrors are detected by an imaging sensor, such as a television camera, and the directions of each of the images at the camera are used to determine all six degrees of positional information of the sensor with respect to the target member.  That information may be used to guide the forklift truck into position relative to a pallet.  The target support member includes retroreflector elements to aid in locating a pallet. Circuit means are provided to flash the light source and in response to the light returned by the retroreflectors to define an area on the image plane of the camera where reflections from the mirrors may be found.  Ambient light images are then temporarily recorded, the light source again flashed, and the ambient images are electronically removed so that only those images due to reflections in the mirrors are finally recorded.

Granted: 1991-05-21
Abstract: PROCESS FOR PREVENTING ELECTRICAL STORAGE            CELL CAPACITY LOSS     ABSTRACT OF THE DISCLOSURE          A process for preventing electrical capacity loss during storage of a pressurized nickel-hydrogen electrical storage cell.   An electrical precharge is applied to the positive electrode of the cell, so that discharge of the cell is negative electrode limited.   In one approach, the cell is charged, while sealed, to a state of charge corres-ponding to a first gas pressure, and then the hydrogen pressure  is  reduced to a lower value,  preferably  about atmospheric.    In  another approach, a current is  passed through the cell while the cell is unsealed and maintained at  atmospheric  gas  pressure, until the cell reaches the desired state of charge.

Title: Thermal stress screening system
Inventor: LESLEY ARTHUR M
IPC: G01N17/00
Filed: 1987-05-12
Granted: 1992-04-28
Abstract: THERMAL STRESS SCREENING SYSTEM             Abstract of the Disclosure An environmental chamber for providing thermal stress screening is comprised of a plurality of modular components which may be quickly assembled and disassembled for ease of maintenance and repair.  In particular, a heater/cooling unit is coupled by means of a plurality of quick release lockable fasteners to a plenum module.  The plenum module in turn is coupled by means of additional quick release lockable fasteners to a blower module.  The plenum module in turn is comprised of a heater plenum which communicates with a blower plenum.      Gas is drawn into the heater plenum and passed over heating coils which are disposed into the heating plenum from the heating/cooling module.  The gas is then communicated to a blower plenum.  Cryogenic nitrogen gas is constantly bled through a small (.015") hole of the liquid nitrogen valve body and is selectively provided to the blower plenum from the heating/cooling module.  The selectively heated or cooled gas is then expelled from the blower plenum by means of a blower which extends into the blower plenum from the blower module.  Selective heated and cooled gas is directed to a part under test as selectively activated through proportional, integral and derivative control in response to the temperature requirements of the part under test and not in response to the gas delivered to the part or from the blower plenum.

Title: Press having a programmable ram with sensing means
Inventor: SWANSTROM KENNETH A
IPC: B21J15/28
Filed: 1987-05-19
Granted: 1991-01-15
Abstract: ABSTRACT OF THE DISCLOSURE     A point of operation safety device for hydraulic or pneumatic presses.  The safety device is computer controlled and limits the movement of the punch by employing two sensing means.  These sensing means include both position and contact sensors which are used as dual input variables to satisfy computer monitored operational condition limits which, if not met, shut down the operation of the machine to prevent accident or injury to the operator.  Both sensing means are located within the housing of the press and the ram assembly so that no additional structures are required which might obstruct the working area and thereby hinder the efficient use of the press.  Because the components of this safety device are located within the body of the machinery and include complicated electronic control circuitry, it is impossible to defeat the safety mechanism by disconnecting any of the components.

Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus (10) for determining while drilling in the earth with a drill bit  (12)  the positions of seismic wave reflecting geologic formations (15, 17) has seismic wave sensors  (A,  B)  positioned in the earth near its surface (42).  The sensors (A, B) are disposed  at  known  positions  with  respect  to  the borehole.  The drill bit (12) generates the seismic waves.  The sensors (A, B) receive the seismic wave both directly and by reflection from the geologic formations (15, 17).  Adaptive filters (20, 26) are connected to each of the sensors (A, 3).  A summing circuit  (34)  receives  outputs  from  the  adaptive filters (20, 26).  The converged impulse responses of the adaptive filters provide information about the amplitude of the reflected waves and their arrival times at the surface, thus allowing detection of the reflecting horizons and their location and physical characteristics.

Title: Method of agglomerating high-potency sweetners
Inventor: ZIBELL STEVEN E
IPC: A23L27/30
Filed: 1987-12-16
Granted: 1999-03-23
Abstract: A process is disclosed wherein a high-potency sweetener is treated so as to improve its handling properties, namely flowability, resistance to caking, and bulk density.  According to the method, a quantity of a powdered high-potency sweetener is mixed with an agglomerating agent, such as a modified cellulose, and a limited quantity of a solvent for the agglomerating agent, such as water.  The quantity of solvent is limited so as to produce a mixture which is only moist or damp.  This damp mixture is characterized as being dust-free, non-flowing and crumbly.  The damp mixture is then dried and the dried mixture is treated, e.g. by grinding and/or screening, to produce the desired particle size range in the agglomerated high-potency sweetener particles.  These agglomerated particles comprise collections or clusters of high-intensity sweetener particles which have been bound together by the agglomerating agent.
