Abstract: An encryption chip is programmable to process a variety of secret key and public key encryption algorithms. The chip includes a pipeline of processing elements, each of which can process a round within a secret key algorithm. Data is transferred between the processing elements through dual port memories. A central processing unit allows for processing of very wide data words, from global memory in single cycle operations. An adder circuit is simplified by using plural relatively small adder circuits with sums and carries looped back in plural cycles. Multiplier circuitry can be shared between the processing elements and the central processor by adapting the smaller processing element multipliers for concatenation as a very wide central processor multiplier.

Title: Process for preparing 1,6 hexanediol and caprolactone
Inventor: RUST HARALD
IPC: C07C27/12
Filed: 1997-02-28
Granted: 2006-04-11
Abstract: The invention relates to a process for preparing 1,6 hexane diol and .epsilon.-caprolacton from a carboxylic acid mixture containing adipic acid, 6-hydroxy caproic acid and, in small quantities, 1,4 cyclohexane diols.  Said mixture is obtained as a by-product of the oxidation of cyclohexane into cyclohexanone/ cyclohexanol with oxygen or gases containing oxygen, by water extraction of the reaction mixture. Said process involves esterification and hydrogenation of a partial stream into hexane diol and cyclization of 6-hydroxy caproic acid esters into caprolacton. According to this process: (a) the monocarboxylic acids and the dicarboxylic acids contained in the aqueous reaction mixture are reacted with a low-molecular alcohol to form the corresponding carboxylic acid esters; (b) the excess alcohol, water and low-boiling agents of the resultant esterification mixture are released in a first distillation stage; (c) separating into a ester fraction substantially free of 1,4 cyclohexane diols, and a fraction containing at least the greater part of the 1,4 cyclohexane diols is carried out from the bottom product in a second distillation stage; (d) at least part of a stream substantially containing 6-hydroxy caproic acid ester is separated from the ester fraction in a third distillation stage; (e) the ester fraction from (d), from which 6-hydroxy caproic acid ester was at least partially removed, is hydrogenated catalytically and 1,6 hexane diol is extracted by distilling the hydrogenated product in a known manner, and (f) the stream substantially containing 6-hydroxy caproic acid ester is heated to temperatures above 200 °C at reduced pressure, thereby causing cyclization of 6-hydroxy caproic acid ester to form caprolacton, and pure e-caprolacton is recovered from the cyclization product by distillation.

Title: Method and apparatus for minimizing chroma subcarrier instability caused by a video line scrambling system
Inventor: QUAN RONALD
IPC: H04N7/169
Filed: 1997-06-17
Granted: 2002-01-15
Abstract: In certain video scrambling systems, composite video is imperfectly separated into luminance and chrominance and scrambled in such a way that an unstable residual chroma color subcarrier remains in the luminance channel. When this unstable residual subcarrier subsequently is summed with stabilized chroma, the resultant composite color signal has small but visible amounts of color subcarrier instability that causes a noisy color signal when descrambled or when displayed on a television display device. A coring circuit is disclosed which provides means for substantially removing the unstable residual chroma subcarrier from the luminance channel, thereby substantially reducing color subcarrier instabilities. An improved coring technique also is disclosed using adaptive chroma coring, which is achieved by adjusting the amount of coring applied in accordance with the amplitude of the chrominance signal. Thus, if the program video input has high levels of color saturation, the chroma coring is electronically turned up. Conversely, if the input video program is essentially in black and white (no color content), then the coring circuit essentially is electronically turned off. The coring techniques also are applicable to enhance the luminance-chrominance separation of video comb filters frequently used in video circuits such as, for example, television sets and video recorders.

Abstract: A telecommunications testing apparatus comprises a signal generator (7) which generates a speech-like synthetic signal, which is supplied to the input of a telecommunication apparatus (1) to be tested. The distorted output of the telecommunications apparatus (1) is supplied to an analysis used (8), which derives, for both the undistorted test signal and the distorted signal from the telecommunications apparatus (1), a measure of the excitation of the human auditory system generated by both signals, taking into account both spectral masking and temporal masking phenomena. The difference between the two excitations is then calculated, and a measure of the loudness of the difference, and the statistical distribution of this loudness over pitch and time, is derived which is found to indicate to a high degree of accuracy the human subjective response to the distortion introduced by the telecommunications system.

Abstract: A packing system for valves includes a preformed packing, an upper packing cup, a lower packing cup, and a threaded bushing or a gland yoke capable of capturing the upper packing cup when the system is installed in a stuffing box. The preformed packing includes an inner cylindrical shell surrounded by an outer cylindrical shell.
