Patent number: 8201514Abstract: A hydrofoil craft, particularly a method of economically modifying a conventional hull with cambered foils to obtain and calculate increased lift from dense spray and to achieve enhanced craft performance is disclosed. The present invention improves speed, fuel efficiency and rough water stability, reduced pitch and vertical accelerations. A catamaran or V-bottom hull is modified with chine mounted airfoils, flexible dihedral cambered foils positioned beneath the water line and on either side of the bow so as to create turbulence in the forward end of a tunnel(s). Tunnels are created on the V-bottom hull by the chine mounted airfoils. Fixed forward tunnel cambered foil(s) and/or fixed or adjustable center tunnel cambered foils at the stern end of the tunnel to generate lift from pressure caused by dense spray in the tunnel(s) may also be provided. Adjustable cambered stern foils are mounted on the transom end of the tunnels.Type: GrantFiled: February 12, 2007Date of Patent: June 19, 2012Inventor: Charles F. Coles

Patent number: 5311274Abstract: A fiber optic refractometer is disclosed for use in on-line measurement of the refractive index of a process fluid. The refractometer does not require light to pass through the process fluid and is hence unaffected by the presence of light diffusing particulate matter in the process fluid. A particular application for which the refractometer is well-suited is the on-line measurement of the hydrogenation state of edible oils (which correlates with refractive index) during the partial hydrogenation process.Type: GrantFiled: May 11, 1992Date of Patent: May 10, 1994Inventor: Charles F. Cole, Jr.

Patent number: 4951591Abstract: Hydrofoil craft, particularly a method of economically modifying a conventional hull by means of foils to obtain enhanced lift and rough water stability. The method is characterized by defining an axial tunnel(s) intermediate the bow and transom of a catamaran hull or V-bottom hull modified with chine mounted aerofoils; positioning a flexible dihedral foil beneath the water line and on either side of the bow so as to obstruct and create a turbulence in the forward end of the tunnel, while cushioning shock and lifting the bow; and simultaneously enclosing the transom end of the tunnel with a foil, so as to compress the turbulence and lift the transom.Type: GrantFiled: December 13, 1989Date of Patent: August 28, 1990Inventor: Charles F. Coles

Patent number: 4538672Abstract: Apparatus for controlling temperature in accordance with a source temperature that includes a clock pulse generating circuit that triggers each of first and second mono-stable multivibrators which provide opposite phase pulse outputs having durations controlled by the R-C time of thermistor sensing components. A retriggerable monostable multivibrator is then controlled in response to pulse duration difference to provide toggle energization of heating and cooling sources.Type: GrantFiled: July 2, 1982Date of Patent: September 3, 1985Assignee: Conoco Inc.Inventors: Raymond C. Overton, Charles F. Cole

Patent number: 4530372Abstract: A level control apparatus is disclosed for controlling a liquid level between a maximum and a minimum. An elastic circuit generates a reference pulse which receives the pulse and triggers the generation of first and second reference pulses. The first reference pulse has a width which corresponds to the function of the maximum level of liquid and the second reference pulse has a width which corresponds to the function of the minimum of liquid. A capacitance probe supplies an output to a level sensing means which generates an output control pulse which varies in time with respect to the liquid level.Type: GrantFiled: September 9, 1982Date of Patent: July 23, 1985Assignee: Conoco Inc.Inventors: Raymond C. Overton, Charles F. Cole

Patent number: 4281547Abstract: The integrity of mine roofs and rock bolts is tested by determining the natural frequencies of the roof and bolt. The roof is struck at a plurality of locations and the resulting vibrations sensed with accelerometers. The output of each accelerometer is separated into a plurality of signals of different frequencies by a comb filter having selected band passes. The amplitude of the outputs of each of the band passes of the filter are used to determine the condition of the roof and bolt adjacent each accelerometer. The high amplitude signal resulting from the initial impact of the striking implement is electrically gated from the accelerometer output.Type: GrantFiled: May 10, 1979Date of Patent: August 4, 1981Assignee: Conoco, Inc. (formerly Continental Oil Company)Inventors: Stanley E. Hinshaw, Charles F. Cole, Jr.

Patent number: 4279078Abstract: A fluid level indicator circuit is used in cooperation with a probe attached to a long wire where the probe has first and second electrodes for contacting the surface of the fluid and leads communicating to the indicator circuit. The water level indicator has a low current high gain transistor and a power source which has sufficient potential to not only properly reverse bias the transistor when the probes are out of contact with the fluid but also properly forward bias when the probes are in contact with conductive fluid. A meter and current adjusting device are provided in series with a collector and emitter to provide an indicator when the probes are in or out of the water. The circuit also has a light to give a visual indication.Type: GrantFiled: February 12, 1980Date of Patent: July 21, 1981Assignee: Conoco, Inc.Inventors: Stanley E. Hinshaw, Charles F. Cole, Jr.

Patent number: 4164871Abstract: An electronic guidance system for a push drill that is remotely guided by the operator. The system functions to maintain continual indication as to the attitude of the drilling apparatus, i.e., pitch, roll and distance to rock formations overlying or underlying the drilled stratum, with such indication being made available to the remote operator so that he can control the progression of the drilling apparatus. The drilling apparatus utilizes an instrument package adjacent the drilling mechanism which samples pitch and roll data through accelerometer output, and which monitors the distance of the drill head from adjacent rock formations by means of gamma ray count.Type: GrantFiled: March 30, 1978Date of Patent: August 21, 1979Assignee: Continental Oil CompanyInventors: Charles F. Cole, Jimmie H. Elenburg
