Title: Photoactivatable leuco base time-temperature indicator
Inventor: BHATTACHARJEE HIMANGSHU R
IPC: B63B21/54
Filed: 1986-12-02
Granted: 1991-07-30
Abstract: ABSTRACT OF THE DISCLOSURE PHOTOACTIVATABLE LEUCO BASE TIME-TEMPERATURE INDICATOR    A photoactivated time-temperature indicator is based on a leuco base system.  A thermally insensitive, white ("inactive") leuco base (or a mixture of such leuco bases) is mixed, preferably in a polymeric matrix, with a material that generates acid upon exposure to light.  Photoexcitation, preferably by UV or near UV light, causes the formation of a thermally sensitive, color-forming ("active") product.  Following this activation step, a progressive color development occurs at a rate that increases with temperature.  The indicator is useful for monitoring the freshness of perishable products, particularly those stored at sub-ambient temperature.

Patent CA-1326071-C (CA)
Inventor: BELMARES-SARABIA ARMAND
IPC: H04N9/74
Filed: 1987-03-02
Granted: 1994-01-11
Abstract: ABSTRACT OF THE DISCLOSURE An improved color correction system and method are disclosed.  A color corrector may include circuits for selecting a predetermined range of colors around an infi-nitely selectable principal color and circuits for selec-tively generating color corrections for the video picture signals which correspond to the predetermined range of colors.  The color corrections are then applied to the video picture signals to produce color corrected video picture signals.  The color corrections may be stored and recalled on a scene-by-scene basis.  Two or more such circuits may be employed so that two or more different principal colors can be selected.  Preferably, the predetermined range of colors is adjustable.  A color corrector may also include circuits for storing and recalling area discrimination signals on a scene-by-scene basis.  Moreover, a color corrector may include circuits for identifying the color corrections for a particular scene with a video picture from that particular scene.  The video picture for the particular scene is displayed, and the operator may recall the color corrections by using the video picture together with an associated control.  More particularly, a miniature reproduction of a frame from each of several prior scenes may be employed to "label" or "tag" the color corrections for the associated scene.  In later scenes, the miniature reproduction may be used to recall the color corrections for the associated scene.  The miniature reproductions may be displayed, for instance, on an auxiliary monitor.  With this  feature, the operator does not have to remember scenes by number, nor is the operator required to run the telecine or tape player backwards to visually select the prior scene whose cor-rections are to be recalled.

Granted: 1991-04-09
Abstract: ABSTRACT OF THE DISCLOSURE           A nonelectric  delay detonator has means  for allowing an ignition flame to be transmitted from an ignition transfer hose to a delay device.  The delay device causes a secondary charge to detonate after a predetermined delay time.  In order to obtain reproducibile delay times of the delay device, a check valve is arranged between one end of the ignition transfer hose and the delay device; this check valve being opened for a short time period due to the excess pressure in the hose and permitting the ignition flame to pass through.   During  deflagration of the delay device, the check valve is closed again so that the delay device burns within a closed system.   In this manner, undefined pressure and gas losses are avoided.

Title: State signal formation for indicating the transition into the bypass mode of operation in an apparatus for high-voltage d-c transmission
Inventor: WILD GEORG
IPC: H02H7/26
Filed: 1988-05-13
Granted: 1991-06-25
Abstract: ABSTRACT OF THE DISCLOSURE      A state signal is formed to indicate a transition to a bypass mode of operation.  In forming the signal of each winding system of a corresponding converter transformer on a side of the converter transformer are determined, weighted with weighting factors and summed up.  The summation current formed in this manner does not have any null zones in the normal operation of the converter.  All weighting factors are different if the phase currents between the converter and the converter transformer are used to produce the summation current. In the case of a converter transformer which is connected to the converter via a delta-connected winding system and in which the winding currents are used, certain differences formed by the weighting factors are not to be the same.  A DC Hall converter with an insertion hole is particularly well suited for weighting and combining the currents of each individual winding system.

Abstract: The present invention relates to a water-gas shift process which is carried out in a liquid medium, either in an ebullated or slurry mode. Heat liberated by the shift reaction is effectively removed by the liquid present thereby allowing for better performance and longer catalyst life.  The process, termed "liquid phase shift" (LPS) preferably uses commercially available vapor-phase low temperature shift (LTS) catalysts to accomplish the shift reaction.  Because of the isothermality of the LPS process and its ability therefore to take advantage of higher catalyst activity, the average operating temperature is typically 260°C (500°F).  This compares favorably to the lower average operating temperature for the conventional vapor-phase LTS process, which is typically 240°C (465°F).  In addition, the LPS process can handle high carbon monoxide content feeds, e.g. 75 vol% carbon monoxide on a dry basis, without experiencing excessive catalyst deactivation.  High carbon monoxide content feeds cannot be handled by convention LTS processing.
