Title: Compensation control for off-premises catv system
Inventor: WEST LAMAR E JR
IPC: H04N7/16
Filed: 1991-11-26
Abstract: A compensation control for an off-premises CATV system includes an automatic gain control and an automatic slope control. A first feedback control (302, 306, 310) is used to compare a first portion of a television signal to a first reference level and null the error. A second feedback control (304, 308, 312) is used to compare a second portion of the signal to a second reference level and null the error. In a second embodiment, the second feedback control differences first and second portions of the television signal. The reference level for automatic gain control is equal to the attenuation between the off-premises equipment and the subscriber premises plus the desired level at the subscriber premises.  The level of a jamming signal is set to fall within a range of power levels related to the reference level.

Title: High pressure discharge lamp provided with a thick film resistor in an outer envelope and a thick film resistor therefore
Inventor: RAVI JAGANNATHAN
IPC: H01J61/82
Filed: 1993-10-22
Abstract: ABSTRACT: High pressure discharge lamp provided with a thick film resistor in an outer envelope and a thick film resistor therefore.     A high pressure discharge lamp having a thick film resistor (34) comprising a plurality of resistive elements. A first resistive element (32) is included in a starting circuit ( 40, 30, 44) for the lamp and a second resistive element (33) is in series with the arc tube during lamp operation for flicker elimination. The integral thick film resistor facilitates mounting and connection of the resistor elements within the lamp envelope (2). Favorably, the resistor substrate has a surface emissivity of greater than about 0.5, and preferably greater than about 0.9, to provide sufficient radiation cooling within an evacuated outer lamp envelope to prevent resistor failure while keeping the size of the resistor small enough for use as a component in an HID lamp. Additionally, a suitable coating of low vapor pressure thickness covers the solder connecting the metallic resistor terminals to the substrate  to prevent evaporation of the solder and its deposition on the inner surface of the outer lamp envelope.

Title: Process for separating off higher alcohols
Inventor: SRIDHAR SRINIVASAN
IPC: C07H15/04
Filed: 1994-08-18
Abstract: ABSTRACT         A process for the extraction of higher alcohols from a mixture of these higher alcohols and alkyl polyglycosides is disclosed, which process uses ethane in the supercritical state as extractant.
