Title: Method of operating a gas turbine group
Inventor: FRUTSCHI HANS U
IPC: F02C7/18
Filed: 1993-04-01
Abstract: ABSTRACT OF THE DISCLOSURE In a method for operating a gas turbine group (32) having an integrated steam process (33) and having an air storage installation (34), a partial mass flow (17) is extracted from a high-pressure turbine (15) of the gas  turbine  group  (32)  and  passed  through  a  heat exchanger (20) for cooling one or a plurality of struc-tures  of  the  gas  turbine  group  (32).    This  heat exchanger (20) is operated by a cooler medium (4, 6). The partial mass flow (17) cooled in this way is subse-quently passed through the structures (18,  19) to be cooled of the gas turbine group (32).  By this means, the cooling is achieved of, in particular, the struc-tures installed downstream of the high-pressure turbine (15).  The heat generator (18) connected downstream and the  low-pressure  turbine  (19)  can  be  connected  in parallel or in series.   It is therefore possible to achieve cooling of the loaded structures of the gas turbine group (32) without, in the process, affecting the working gas balance of the installation.           (Fig.)
Patent CA-2095087-A1 (CA)
Inventor: FISCHER ADDISON M
IPC: G06F21/24
Filed: 1993-04-28
Abstract: Method and apparatus are disclosed including a system monitor which limits the ability of a program about to be executed to the use of predefined resources (e.g., data files, disk writing capabilities, etc.).  The system monitor processes a data structure including a set of authorities defining that which a program is permitted to do and/or that which the program is precluded from doing.  The set of authorities and/or restrictions assigned to a program to be executed are referred to as "program authorization information" (or "PAI"). Once defined, the program authorization information is thereafter associated with at least one program to be executed to thereby delineate the resources and functions that the program is allowed to utilize and/or is not allowed to utilize.  The PAI associated with a particular program may be assigned by a computer system owner/user or by someone who the computer system owner/user implicitly trusts.  The PAI permits an associated program to access what has been authorized and nothing else.  The program may be regarded as being placed in a program capability limiting "safety box".  This "safety box" is thereafter associated with the program such that when the system monitor runs the program, the PAI for that program is likewise loaded and monitored.  When the program is to perform a function or access a resource, the associated PAI is monitored to confirm that the operation is within the defined program limits.   The program is prevented from doing anything outside the authorized limits.

Abstract: ONE-PIECE THERMALLY RESISTANT GIMBAL GIMBAL DEVICE FOR A REPLACEABLE HEADLAMP BULB                              ABSTRACT      A replaceable headlamp bulb for automotive applications comprising a discharge light source, a gimbal device, and a plastic lamp bass in which the gimbal device is a one-piece construction that allows the light source to be precisely aligned and locked in a specific position with respect to the lamp base. The gimbal device is a cylindrically shaped member made of glass-mica material with a metallic ring fitted in a castellated circumferential groove at one end of the glass-mica member. The light source is mounted at the opposite end of the gimbal device to the ring fitted portion. The plastic base contains an internal cylindrical opening into which the ring-fitted end of the glass-mica gimbal is inserted and aligned with respect to the plastic base. The gimbal device is locked inside the plastic base by heating of the metallic ring using Radio-Frequency (RF). During the RF heating the mica material reacts in the vicinity of the metallic ring which is seated inside the castellated groove to lock the gimbal to the ring. Ring sizing tolerance can be relaxed because the gaps between the castellations on each side of the groove walls serve to accommodate an oversized ring so that the ring is contained within the groove.

IPC: G06T3/40
Filed: 1993-10-19
Abstract: Raster display memories are often arranged to output groups of pixels in progressive blocks, each having a plurality of pixels and each pixel having a plurality of fields. The fields in each, pixel may provide color, overlay and cursor information for an individual position on a video screen. The numbers of bits in each pixel and in each field may be variable in different applications. In this system, control information indicates the starting position of each block, the location of each pixel in each block and each field in each pixel and the width of each pixel and each field in number of bits. Using this control information, the system recovers the pixels in each block and the fields in each pixel and processes such information to provide a display of the pixel information on a video screen. The number of bits contained in each field may be expanded to a width (e.g. 8) when the field width is less than eight (8) bits. In this expansion, the expanded field value has an error, compared to the field value before expansion, less than half of the least significant bit in the expanded field. Frequently, the bits in each field before expansion are provided in the positions of greatest binary significance in the expanded field. The unused positions in the expanded field are then filled in the order of progressively decreasing significance by the bits of progressively decreasing significance in the field before expansion, starting from the bit of greatest significance.

Title: Vinyl Acetate Catalyst Preparation Method
Inventor: NICOLAU IOAN
IPC: B01J23/52
Filed: 1993-10-08
Abstract: A method of preparing a catalyst particularly useful in the reaction of ethylene, oxygen and acetic acid in the vapor phase to form vinyl acetate comprises impregnating a porous support with water soluble salts of palladium and gold, fixing the palladium and gold on the support as water insoluble compounds by immersing the impregnated support in a reactive solution and tumbling the impregnated support in the reactive solution for at least 1/2 hour to begin precipitation of the insoluble compounds and completing precipitation of the insoluble compounds on the support and reducing the insoluble compounds to free palladium and gold. The catalysts prepared in this manner have been shown to provide improvement with respect to reduced selectivity to CO2, during the vinyl acetate forming reaction.
