Inventor: VETTER GREGORY J
IPC: E05F11/16
Filed: 1992-11-24
Abstract: An operator for a French casement window having an operating arm with a roller mounted at its end and pivotable to move in an arc between extended and retracted positions, and a channel member horizontally mountable on the inner side of one sash and confining the roller as the operating arm is moved between its extended and retracted positions to move one between open and closed positions, respectively. A bracket is on the inner side of the other sash adjacent its outer vertical side, and a drag link is pivotally connected on one end to the bracket and on the other end to the operating arm to move the other sash between open and closed positions synchronously with the first sash when the operating arm is moved between its extended and retracted positions, respectively. The drag link may be selectively in or out of alignment with the operating arm pivot axis when the sashes are in their closed position, whereby one sash is closed slightly ahead of the other when the sashes are moved to their closed position and the other sash is moved slightly ahead of the one sash when the sashes are moved from their closed position toward their open position. A sealing flange along the middle vertical side of the one sash sealingly engages the inner side of the other sash, and a second sealing flange along the middle vertical side of the other engages the outer side of the one sash, when the sashes are in their closed position.

Title: Musical entertainment system
Inventor: GIBSON BRIAN C
IPC: G11B31/00
Filed: 1993-03-03
Abstract: Disclosed is a karaoke-type entertainment system that allows a participant to sing along with a prerecorded song. The system includes a microphone for producing an input vocal signal that corresponds to the singer's voice, and a pitch corrector samples the input vocal signal and determines its pitch. The pitch corrector shifts the pitch of the input signal to correspond to the pitch of a reference note which in turn corresponds to the correct pitch at which the melody is to be sung. The pitch corrector thereby alters the pitch of the input vocal signal to correspond to the pitch of the reference note so that the participant is singing "on pitch" with the melody.

Title: Method for quick characterisation of alkyl polyglycosides
Inventor: BALZER DIETER
IPC: C09K23/56
Filed: 1993-09-15
Abstract: ABSTRACT         The invention relates to a new method for quick characterisation of alkyl polyglycosides of the formula R-O-Zn in which R represents a linear or branched, saturated or unsaturated alkyl radical having 8 to 20 carbon atoms and Zn represents an (oligo)glycosyl radical having on average n = 1 to 5 hexose and/or pentose units, or mixtures thereof.          According to the method, the alkyl polyglycoside is titrated in aqueous solution with an agent at a specified temperature until clarification or clouding occurs, or the turbidity point is determined after addition of an agent.  According to one preferred embodiment, surfactants or mixtures thereof are used as the agents.  The alkyl polyglycoside may be characterised, for example, by the titre of the agent at a specified temperature or the consumed volume of the titrating agent of a specified concentration.  These characteristics are very sensitive to changes in the structure of alkyl polyglycosides,  such as the degree of glycosidation or the alkyl chain length.

Abstract: Abstract A novel atomic frequency standard includes an absorption cell containing a first volume of atoms for varying an intensity of light energy passing therethrough; at least one dielectric resonator for generating an evanescent electromagnetic field that effects hyperfine energy level transitions of the first volume of atoms; a waveguide for housing the absorption cell and one or more dielectric resonator(s); a photo detector mounted near an end of the waveguide for receiving light energy; and an electromagnetic energy injector for electromagnetically exciting the dielectric resonator(s).  Preferably, a filter cell is positioned adjacent to a dielectric resonator between the absorption cell and the light source.  Tuning of the resonant frequency of the dielectric resonator(s) can be accomplished by adjusting the distance between the filter cell and the adjacent dielectric resonator, and can also be accomplished by positioning a dielectric tuning disk adjacent a dielectric resonator, and adjusting the distance between the dielectric resonator and the dielectric tuning disk.

Title: Methods for alloy migration sintering
Inventor: FELDSTEIN ROBERT S
IPC: B22F1/17
Filed: 1992-10-20
Abstract: Methods for fabricating a sintered element from unsinterable material, utilizing the property that it will form a eutectic composition or alloy with a suitable alloying agent at a temperature which is below the plastic deformation temperature of the material. Discrete particles of the material to be sintered are coated with a thin coating of the alloying agent and are packed into position to be sintered. Then, the coated grains or wire pieces are heated so that at least the coating and the regions of the grains just below the coating are slowly raised in temperature. Diffusion regions of alloying agent into the grains of the sinterable material will occur. Further heating continues so at least the diffusion regions increase in temperature to slightly above the eutectic melting point. Localized melting of the diffusion regions occurs where the eutectic concentration is reached, and adjacent grains begin to share the localized melting regions and become mutually wet. The alloying agent continues to diffuse, and drops in concentration, so that it freezes out of the localized melting regions. The melting point of the melting regions tends to rise, and the wetted melted regions freeze to form a sintered and solid element.

Abstract: A method and system for locating field breaks within input data is provided. In a preferred embodiment, a software facility locates field breaks within input data. The facility first receives input data made of a large number of rows of text. The facility then selects a group of the received rows of text to analyze. The facility identifies field breaks within the input data by analyzing the selected group of rows of text. The facility preferably analyzes the selected rows by counting the number of substantive characters in each column of the selected rows. The facility then uses the count to determine which columns have less than a field-break threshold of substantive characters. The facility locates one field break within each series of columns that have less than the field-break threshold of substantive characters.
