Patent number: 5981916Abstract: A cooking appliance includes a heating unit (10) for cooking food. The unit has a heating element (34) to which electrical current is supplied for generating heat used to cook food such as chocolate and sauces set upon the heating unit. A programmable controller (16) controls the application of current to the heating element to control the heating element temperature as a function of a time and temperature profile established for cooking the food in a particular manner. A temperature sensor (38) senses the heating element temperature and supplies a signal (St) to the controller. The characteristics of this signal are a function of the sensed cooking temperature. The controller is responsive to this signal, and other inputs (24,26) such as desired cooking time, and the amount and quantity of food, to vary the amount of current supplied to the heating element. The appliance is particularly useful in being able to heat chocolate, sauces, and the like without scorching them.Type: GrantFiled: June 12, 1998Date of Patent: November 9, 1999Assignee: Emerson Electric Co.Inventors: Simon P.

Patent number: 5954981Abstract: A bracket (12) for installing a replacement heating unit (R) in place on a cooktop (C). One leg (14) of each of a pair of L-shaped brackets (12a, 12b) is attached to the bottom (B) of a pan portion (P) of the heating unit. The pan portion is smaller in diameter than the diameter of the opening in the cooktop where the replacement unit fits. The other leg (16) of each bracket extends upwardly along the side of the pan and is spaced outwardly of the pan. This other end of the bracket fits behind a downturned lip (L) defining an opening (O) in the cooktop in which the replacement unit is fitted. This allows the heating unit, with the brackets attached, to be set in place in the cooktop opening with the upwardly extending legs of the brackets bearing against an inner portion of the opening sidewall so to fit the replacement heating unit in place.Type: GrantFiled: August 20, 1998Date of Patent: September 21, 1999Assignee: Emerson Electrict CompanyInventors: Subhash R.

Patent number: 5880440Abstract: An electrical resistance heater (12) has an elongate electrical heating coil (C) with a plurality of convolutions (C1, C2). An electrical insulator (10) supports the convolutions and includes an insulator body (18) mountable to a support frame (19). A generally circular projection (20) extends from one side of the body and is integrally formed therewith. A generally arcuate section (26, 28) of the projection, on opposite sides of the projection, is spaced from an adjacent surface (30, 32) of the body. A notch (34, 36) is formed by the respective surfaces of the body and the projection for respective coil convolutions (C1, C2) to be received in the respective notches. The upper end (42, 44) of the faces (38, 40) of the projection are tapered outwardly from the top of the projection to facilitate coil installation. A shoulder (30s, 32s) formed on the insulator body adjacent each notch helps retain the coil convolutions in the notches.Type: GrantFiled: November 7, 1997Date of Patent: March 9, 1999Assignee: Emerson Electric Co.Inventors: Charles T.

Patent number: 5755284Abstract: A rod guide is provided for centering a sucker rod within a tubular string that powers a pump within a wellbore. The rod guide comprises a rotor secured to the sucker rod and having upper and lower stop surfaces thereon, and a sleeve formed from metal to substantially increase the life of the rod guide. The rod guide stator has an elongate slot extending along its axial length. The stop surfaces limit axial travel of the stator on the sucker rod, and the sleeve prevents the stator from engaging the sucker rod. The sleeve may be retained on the rod by a clip, and plastic end members then molded over the clip and the ends of the metal sleeve. The stop surfaces may be formed by a ring member spaced axially between the upper and lower ends of the sleeve.Type: GrantFiled: March 20, 1997Date of Patent: May 26, 1998Assignee: Flow Control Equipment, Inc.Inventors: Charles M. Hart, H. Milton Hoff, Randall G. Ray, Stephen L. Witte, Sr.

Patent number: 5628485Abstract: An insulated drink holder attachable to a lawn chair or the like. The drink holder includes a receptacle for holding a beverage container, and a two part clamp attached to the receptacle. One side of the clamp is formed by an arm projecting laterally from the receptacle. In alternative embodiments, the other side of the clamp comprises a member adjusted in discrete steps by a peg and socket arrangement, or a spring urged jaw pivotally mounted to the arm. Resilient cushions are located on the upper and lower sides of the clamp to conform to the lawn chair frame being grasped, and to prevent the drink holder from gimballing. In both embodiments, flexible straps bearing hook and loop fastener are tightened around the clamp to further improve grip. The novel drink holder cooperates with lawn furniture having either tubular or square channel frame members.Type: GrantFiled: December 13, 1994Date of Patent: May 13, 1997Inventor: Cheryl G. Ray

Patent number: 5462618Abstract: A method of forming a pultruded shaped composite material comprising carbon fiber having a diameter not greater than 0.001 inch aligned linearly with a degree of waviness defined by an average amplitude to length (A/L) ratio of less than 0.9 percent in a matrix is formed around the fiber and solidified or cured into a rigid form that will not melt during subsequent processing steps to prevent an increase in waviness during subsequent processing steps. The compressive strength of the composite material approaches the tensile strength of the material. The matrix material consists essentially of a resin present in the range of about 10 to 50 percent by volume of the composite material. The A/L ratio is determined by measuring the distribution of angularity found in the aligned carbon fibers in a selective cross section cut at five degrees to the fiber plane, wherein the standard deviation for a 300 sample angularity measurement is not greater than 0.88 degrees.Type: GrantFiled: June 2, 1994Date of Patent: October 31, 1995Assignee: Bell Helicopter Textron Inc.Inventors: Charles W.
