Abstract: A system for measuring cyanides in a sample employs a photoillumination component for producing ultraviolet radiation to dissociate cyanides contained in an alkaline sample. The system includes filtering components interposed between the photoillumination components and an alkaline sample to be tested for passing lower frequency ultraviolet radiation to produce an irradiated sample in which cyanides have been dissociated, while blocking high frequency ultraviolet radiation to inhibit thiocyanate dissociation. Thin-film distillation components are included for separating cyanide from the irradiated sample to produce recovered cyanide for measurement purposes, and measuring components are provide for receiving the recovered cyanide generating a recordable signal indicative of recovered cyanide quantity.

Abstract: The object of the invention was to develop a highly selective process for the preparation of uretdiones of (cyclo)aliphatic diisocyanates which does not rely on the use of catalysts which are difficult to prepare and involve a cancer risk. 
<??>This is achieved by reacting (cyclo)aliphatic diisocyanates having 6 to 15 carbon atoms or mixtures thereof in the presence of 4-dialkylamino-substituted pyridines until a degree of dimerisation of 10 to 80 % is reached and subjecting the reaction mixture to a vacuum thin-film evaporation, in which the uretdione is formed as the distillation residue. 
<??>The process is suitable in particular for the preparation of the uretdione of isophorone diisocyanate, which in turn is used in polyurethane paints.

Abstract: Circuitry for producing an extremely linear frequency modulated audio carrier for use in the headend of a video signal distribution system, such as a cable television system. A reference oscillator (10) operating at a relatively high frequency, such as the video carrier frequency, generates a signal which is divided down (18) to a relatively low frequency. A voltage controlled oscillator (24) operating at the relatively low frequency is used to frequency modulate the audio signal. After modulation, the audio carrier is upconverted (28, 42) utilizing a signal frequency which is also derived from the original reference frequency, thus providing a stable and linear frequency modulated audio carrier particularly suitable for transmission of stereo program audio.

Title: Optical notch filter for discriminating against coherent radiation
IPC: G02F1/11
Filed: 1988-07-05
Granted: 1993-03-10
Abstract: A self-tuning optical notch filter is employed to separate coherent from noncoherent radiation in an overall beam. The presence of coherent radiation is detected, preferably with an interferometer, and the frequency of the detected coherent radiation is determined. An electrical control signal is generated with a frequency corresponding to that of the coherent radiation, and causes an optical filter to filter out the coherent radiation from the beam. In the preferred embodiment the optical filter is a Bragg cell, and the electrical control signal is applied to an electro-acoustic transducer which furnishes an acoustic control signal to the Bragg cell.

Abstract: A method for increasing the ratio of 2-methyl-2-butene (2MB2) to 2-methyl-1-butene (2MB1) in isoamylenes involves fractionating a feedstream containing tertiary amyl methyl ether (TAME) and isoamylenes including 2MB2 and 2MB1 in a ratio of about 2:1 to effect a separation between an overhead hydrocarbon fraction of isoamylenes including 2MB2 and 2MB1 in a ratio of about 1:1, a bottoms fraction including TAME, and a sidestream hydrocarbon fraction consisting essentially of isoamylenes including 2MB2 and 2MB1 in a ratio of about 6 to 12:1, recovering the sidestream hydrocarbon fraction, and recycling the overhead hydrocarbon fraction of isoamylenes to form a mixture which is subsequently reacted to form the feedstream. Prior to fractionation, the feedstream is formed by passing isoamylene, and optionally TAME, in a vapor phase over an ether cracking catalyst which isomerizes isoamylene and converts 2MB1 to 2MB2, i.e., the feedstream for fractionating, which contains 2MB2 and 2MB1 in a ratio of 2 to 5:1. A method for converting 2-methyl-1-butene to 2-methyl-2-butene which may be used to form the feedstream for fractionating involves providing a hydrocarbon stream comprising isoamylenes including 2MB1 and 2MB2 in a ratio of within the range of 1:1 to 5, adding about TAME to the isoamylenes to form a mixture which is passed in the liquid phase at a temperature and an LHSV which favors isomerization over an acidic ion exchange resin catalyst to produce a reaction product including 2MB1, 2MB2 in a ratio of 1:6 to 12, and TAME.

Title: Process for heating elongated stock

Granted: 1992-08-12
Abstract: A process for heating elongate metal material (2), for example elongate aluminium, in stepwise passage through a plurality of series-arranged, separately controllable heating zones (A, B, C), for each of which an intended temperature is preset and monitored at a check-measuring point, the elongate metal material (2) is, after it has reached the intended temperatures, conveyed forward by the distance A + X for shearing off a block of length X and, after this block has been sheared off, conveyed back by the length A, A being the distance between the front end of the metal material located before the forward-conveying in the last heating zone (d) and the shears (3), the temperatures on the surface of the metal material at the check-measuring point of at least the first heating zone (A) and at a measuring point offset rearwards therefrom by the length L are detected immediately before the metal material is conveyed forward, with L >/= X. From these two temperature measurements, the temperature gradient is determined. Starting from this, that heating power is determined and applied which, after the forward-conveying by the length A + X and the back-conveying by the length A, gives again essentially the intended temperature at least at the check-measuring point of the first heating zone. The required heating power can, on the basis of these measurements, also be calculated for the next and/or further heating zones, for which the determination of a temperature gradient between the check-measuring points of successive heating zones can be helpful. <IMAGE>

Title: Human-in-the-loop machine control loop
IPC: B25J13/02
Filed: 1989-05-22
Granted: 1993-07-28
Abstract: In a human-in-the-loop robotic control loop, the constrained forces and moments at the gripper (5) (also called hand or end effector) of the manipulator (1) are measured by a force-mement sensor (4). The resulting force and moment signals are scaled and fed as input voltages to motors (26,34,51) in a hand controller to provide torques which oppose deflection of the hand controller. Thus, the operator feels the opposing torques which are proportional to the magnitude of the constrained forces and moments. The force feedback loop may be opened to selectively provide a passive control loop. In either the active or passive mode, the hand controller position signals may be selectively mapped to either gripper position signals or gripper velocity signals in order to control movement of the gripper in the desired manner.
