Abstract: A PROCESS FOR PREPARING DERIVATIVES OF (HALO)AMINO-1,3,5-TRIAZINES BY CARBONYLATION                           ABSTRACT OF THE DISCLOSURE Provided is a process for preparing carbonylated derivatives of amino- and haloamino-1,3,5-triazines by contacting the 1,3,5-triazine, carbon monoxide and a metal catalyst system containing a metal promoter for promoting carbonylation, at a temperature carbon monoxide pressure and length of time sufficient to carbonylate at least a portion of the amino and/or haloamino groups of the 1,3,5-triazine. The product resulting from contacting these components is an isocyanate functional 1,3,5-triazine; however, the carbamate functional derivative can be readily produced by contacting these components in the further presence of a hydroxy compound, or by post-reacting the isocyanate functional product with such hydroxy compound.

Inventor: SCHULTE WOLFGANG
IPC: H04N13/307
Filed: 1992-12-10
Abstract: The projector has an essentially afocal projection system, in particular for the reproduction of three-dimensional images. This system has a system of convex lenses (1) on the side of the object and a Fresnel lens (2) on the side of the image. The lenses are larger than the transverse dimension of the object to be reproduced. By providing a double reflection (3, 4), this projection system is able to generate, in addition to the reproduction of two-dimensional images, a three-dimensional image of a real, three-dimensional object, "positioned in space" and whose sides are correctly aligned for the benefit of an observer. Preferably, a plane mirror (3) is used for this purpose as well as a beam splitter (4) that is inclined by about 45° with respect to the main axis (5) of the system of convex lenses (1).

Title: Water heater
Inventor: DOSANI NAZIR
IPC: F24D19/10
Filed: 1994-07-04
Abstract: A controller for a water heater provides a mixing valve mixing cold water from the cold water supply with hot water from the water heater, to control the temperature of water in the hot water distribution system.  This allows the temperature in the water heater to be much higher than normal, without any scalding hazard.  In a preferred embodiment the controller applies the formula hot water output temperature - consumption temperature consumption temperature - cold water supply temperature to set the mixing valve.  Also, in a preferred embodiment the controller senses the temperature and/or current draw of an activated heating element, and switches to an alternate or auxiliary element in case of heating element failure.
Patent CA-2127757-A1 (CA)
Inventor: MASON ARTHUR C
IPC: B23Q1/54
Filed: 1994-07-11
Abstract: A mechanical loading device capable of generating a substantially rectilinear output motion for the purpose of transporting workpieces between work stations.  The mechanical loading device is capable of producing the rectilinear output motion such that a workpiece is lifted, transferred horizontally, and then lowered into position with a significant degree of precision.  The rectilinear output motion is generated primarily by a carrier on which a yoke is supported with an eccentric shaft extending from a driven member mounted to the carrier.  The eccentric relationship between the driven member and the yoke, in conjunction with the controlled rotation of the carrier, generates the rectilinear output motion at an output member supported by the yoke.  The mechanical loading device is structurally strong and compact, is constructed so as to be readily maintainable, and enables the efficient conversion of a rotational input motion to the desired rectilinear output motion.

Title: Method for Preparing a Coffee Beverage and a Coffee Machine for Performing the Method
Inventor: ACKERMANN ANTON
IPC: G07F9/10
Filed: 1994-10-27
Abstract: In a method for preparing coffee drinks with the help of a plu-rality of coffee powder portions arranged along a transporting tape, a single coffee powder portion is removed from a storage container by pulling out the transporting tape to such an extent that the following coffee powder portions remain in the container.          Then, the tape is cut behind the first coffee powder portion, and the new initial portion of the transporting tape is fixed in the region of the outlet opening of the container. In this way, the unused coffee powder portions remain fresh and keep their full flavor, even during an extended storage period.   The coffee machine suitable for performing this method com-prises a two part brewing chamber. One portion of the brewing chamber is not only movable to and fro the other portion, but also rotatable and furthermore equipped with a catch member for grasp-ing the initial portion of the transporting tape.

Title: Double knife stubble cutter
Inventor: BLOSSER KEN
IPC: A01D34/03
Filed: 1995-03-23
Abstract: A double knife stubble cutting machine is provided for cutting stubble after a harvesting action into three separate pieces including a standing stubble piece and two cut pieces. The device comprises a frame having a center section and a pair of wing sections with the wing sections being pivotal about a horizontal axis upwardly to a transport position. The frame defines a tool bar across the full width of the frame which carries a pair of sickle knife support bars downwardly of the tool bar and arranged so that one sickle knife is forwardly of and upwardly of the second sickle knife. Both knives are open and free from support elements between the knives so that the cut material can be discarded back to the ground after cutting without any transverse movement or blockage. The harvesting action therefore allows the minimum amount of straw to be taken by the combine harvester so that the standing stubble element is cut into three pieces of equal length. The space in between the cutter knives is adjusted by twisting the support beam.

The pk data point is determined (42) such that k satisfies the relationship (I): i-I/M < k/N <  i/M, where M is the total number of quantile partitions and i is the ith quantile partition. The object is identified based upon the pk data point value, which is the ith quantile in M partitions developed from the above relationship.
