Title: Foam stabilized watercraft
Inventor: HANSEN WILLIAM M
IPC: B63B59/02
Filed: 1993-01-13
Abstract: A high performance boat stabilized through the use of foam stabilizing members (12) is provided. The boat has a rigid, planing hull (10) including a transom (14), and a pair of curved sides (16) extending forward from the transom to form a bow. A bottom (18) is joined to the sides forming a chine (20). The foam stabilizing members (12) are mounted on the sides of the hull above the chine (20) and extend from the transom along the length of the boat. The sides of the boat also include an upper (52) and lower (54) Mange extending outwardly from the sides of the boat adjacent to the upper and lower edges of the stabilizing members at the location where the stabilizing members attach to the sides of the hull. The lower Mange (54) helps to ensure that water is not forced in between the sides of the boat and the stabilizing members, thus preventing possible damage to the boat. Additionally, the stabilizing members are attached to the side of the hull without the use of holes extending from the exterior to the interior of the hull, thus preventing water from seeping into the hull.

Title: Switch-contact-cleaning circuit
Inventor: ROBERTS PATRICK S
IPC: H01H1/60
Filed: 1993-03-15
Abstract: ABSTRACT     A precharged capacitor connected in parallel with the contacts of an open switch discharges through the switch upon closure.  Oxides on the switch contacts are broken through upon closure of the switch to produce a good electrical connection.  The capacitor provides sufficient voltage and transient current to clean the switch contacts.  A microprocessor having signals of only 5 volts can interrogate a plurality of such switches by multiplexing same semiconductor switching circuits that energize the interrogated switches and by synchronously multiplexing some microprocessor input circuits. The microprocessor's input circuits therefore receive signals indicating the status of each switch in turn.

Title: Single plane trim balancing
Inventor: THOMAS THUMPASSERY J
IPC: F02B3/06
Filed: 1992-10-01
Abstract: A method for balancing a rotor of an alternator in a diesel-electric locomotive in which the rotor is drivingly coupled to a power output shaft of a diesel engine. A speed sensor and a vibration sensor are coupled to the rotor for providing output signals representative of instantaneous rotational velocity and instantaneous amplitude of vibrational motion of the rotor, respectively. In the inventive method, the rotor is accelerated to a first preselected rotational velocity and a first rotor unbalance is determined from the velocity and vibration signals. The rotor is then accelerated to a second preselected rotational velocity and a second rotor unbalance is determined. The first and the second rotor unbalance determinations are combined to identify a first correction weight and position thereof for minimizing the first and the second rotor unbalance. The identified weight is installed and the process repeated until the unbalance is corrected such that vibration is less than a preselected maximum value.

Title: Method and apparatus for optically screening microscopic cells
Inventor: HAJEK CONSTANCE M
IPC: G01N33/48
Filed: 1991-11-22
Abstract: ABSTRACT        An optical  screening method and apparatus  for identifying   both   the   morphology   and   selected characteristics or properties expressed by cells, such as cancer cells.  The cells are combined with one or more different  sets  of  microspheres,  each  set  having  a reactant bond thereto which will bind to a specific molecule which can exist on one or more types of cancer cells.  The cells and microspheres are formed as a smear on a slide, stained with a histological type stain and optically viewed to identify the type of cells to which the different sets of microspheres do or do not bind. The  different  sets  of  microspheres  are  optically differentiated by    having    different    optical characteristics,   such  as  size,   shape,   color  or combinations thereof.   A fast cancer cell  screening method or panel is provided by adding different sets of microspheres having different reactants bound thereto to different sample portions and optically screening the different sample smears.  The microspheres also can be removed  from a  sample portion with any cells  bound thereto  and  compared to  another  non-modified  sample portion to ascertain if the cancer cells of interest have been removed from the sample portion.

Abstract: A method and apparatus for determining the position and orientation of a remote object relative to a reference coordinate frame includes a source having a plurality of field-generating elements for generating electromagnetic fields, a driver for applying, to the generator element, signals that generate a plurality of electromagnetic fields that are distinguishable from one another, a remote sensor having a plurality of field-sensing elements for sensing the fields generated by the source, and a processor for processing the outputs of the sensing elements into remote object position and orientation relative to the source reference coordinate frame. The processor compensates the position and orientation values as a function of displacement of either the field-generating elements from a common center, or the field-sensing elements from a common center, or both. Techniques are disclosed for compensating for small-scale non-concentricity in order to overcome imperfections in the orthogonal coil sets wound on a common core, each set defining the source or the sensor.          Techniques are also disclosed for compensating for large-scale non-concentricity to allow physical separation of the coil set defining  the source or the sensor to dispersed locations that may be more desirable for a particular application.

Inventor: KUZE YOSHIKAZU
IPC: G05B9/02
Filed: 1993-11-10
Abstract: READ-ONLY SEQUENCE CONTROLLER      A read-only sequence controller has a main circuit and a sub-circuit operated by a command signal from the main circuit at a predetermined cycle time.  The cycle time of the main circuit is longer than the sub-circuit in order to control the sub-circuit.  A sensor is provided on an outlet of a machine for detecting a discharge of a work at every cycle end and producing a discharge signal which is fed to the sub-circuit.  In normal operation, the sub-circuit is re-started in response to the discharge signal and the command signal from the main circuit.  When abnormality occurs, the sensor does not produce the discharge signal.  In response to absence of the discharge signal and to the command signal, a stop control circuit produces stop signals to stop the main circuit and the sub-circuit.

Title: Brake Actuator Assembly Including Twin Cam Members
Inventor: GEE THOMAS A
IPC: F16D65/22
Filed: 1994-02-10
Abstract: A brake actuator assembly is disclosed for expanding internal shoe brakes in which a pair of brake shoes (17) are disposed with a brake drum (11). A pair of cam members (33, 35) are fixed to a pair of cam shafts (41,43) and are operable to engage the brake shoes by means of cam follows (37,39), in response to a brake input (56.55). The cam shafts (41,43) are timed relative to each other by a pair of gears (73,75). The disclosed actuator assembly ensures that the cam members rotate through the same angular magnitude, but the amount of torque transmitted to each cam is determined by the braking force required for the respective brake shoe. The disclosed actuator assembly provides for substantially greater lift, for longer shoe wear life, without taking up as much space in the radial direction as would an equivalent S-cam arrangement.
