Title: Improved support arrangement for optimizing a low pressure steam turbine inner cylinder structural performance
Inventor: GROENENDAAL JOHN C JR
IPC: F01D25/24
Filed: 1992-01-31
Abstract: 56,128 ABSTRACT Apparatus is provided for increasing the bending flexibility of the horizontal joint flange of a low pressure steam turbine.   The radial width of the horizontal joint flange in the support area where the turbine inner cylinder rests on the outer cylinder has been significantly reduced. In order to accommodate a reduction in the radial width of the flange in this area, the present invention provides a novel arrangement of the functional features of the cylinder support area.  In a preferred embodiment the horizontal joint flange is capable of being narrowed in the radial direction due to the strategic rearrangement of the functional components in the  support area.   The present  invention also provides retrofit steps for modifying existing turbines in order to provide the features and benefits of the improved apparatus. The present invention reduces ovality of the turbine inner cylinder rings, resulting in improved thermal performance and mechanical reliability as well as a reduction in flange induced, non-axisymmetric bolt loads in the horizontal joint flange bolts.

Abstract: Un dispositif pour la vérification d'un thermographe se compose d'une plaque support de modèle (32) comprenant des impressions (P0, P1, P2 et P3) en profondeur. Les impressions (P0 et P1) présentent la même fréquence dans l'espace, alors que les impressions (P2 et P3) présentent respectivement des fréquences dans l'espace relativement supérieures. Les impressions (P0 et P3) ont la même structure et la même orientation, et elles se trouvent respectivement sous-jacentes aux corps noirs (34, 26, 28 et 30). Les températures différentielles entre les corps noirs (34 et 26 à 30) sont maintenues à des valeurs constantes par des circuits de commande de la température. La température du corps noir (34) est réglable. La plaque support de modèle (32) et les corps noirs sous-jacents sont visualisés par un thermographe sous le dispositif de vérification. La température du corps noir (34) est réglée jusqu'à ce que l'impression (P0) soit juste identifiée comme étant froide par rapport à la plaque support de modèle (32). Si la performance du thermographe est acceptable, les impressions (P1 à P3) sont alors juste discernables comme étant chaudes par rapport à la plaque de support de modèle (32).

Abstract: A method for use in a system of the type capable of manipulating digital images represented by a plurality of original image pixels is provided. In the preferred embodiment, the system has a memory for storing images and an image output terminal. Additionally, the method includes a step of deriving an intensity value for a selected output pixel in a set of output pixels from a plurality of input pixels in a set of input pixels, each of the plurality of input pixels having a corresponding intensity value contributing to the intensity value of the selected output pixel. The step of deriving the intensity value of the selected output pixel preferably comprises the steps of mapping, in the memory, the set of output pixels to the set of input pixels so that each of the plurality of input pixels is adjacent the selected output pixel, as well as reading the plurality of input pixels from the memory. After determining a correlation value for each of the plurality of input pixels with a correlation function, the correlation values of the plurality of input pixels can be summed with the corresponding respective intensity values of the plurality of input pixels to obtain the intensity value of the selected output pixel.

Title: Plastic standpipe support for a load-bearing adjustable column
Inventor: COHEN YOAV
IPC: A47B9/10
Filed: 1992-05-01
Abstract: Plastic Standpipe Support for Load-Bearing Adjustustable-Length Column Abstract A plastic standpipe for an adjustable-height support column for a chair or the like to replace the conventional metal standpipe which supports the height-adjustable device, e.g., a pressurized fluid spring. The novel standpipe is a unitary, molded generally tubular member formed of high strength, and preferably low-friction, plastic material.  A plurality of circumferentially-spaced, radially-extending support ribs, with flexible arc-like members at their inner ends, are formed on the inner wall of the tubular member, such that the arc-like members contact the spring cylinder and form a floating circumferential support ring which allows for some lateral freedom of movement of the upper end of the spring cylinder.  The interior ribs perform the dual functions of guiding axial movement of the spring cylinder with flexibility during height adjustment and providing sufficient rigidity to the column to support the loads placed on it.  A representative composition of the plastic material is fiberglass-reinforced nylon and an impact modifier, such as a ter polymer, comprising ethylene, acrylic acid and maleic anhydride, or a rubber-like polymer.

Filed: 1991-10-30
Abstract: A fall-arrest apparatus comprises a drum (1) which holds a cable (3) for attachment to a load and has a brake (7-11, 13-15) which automatically stops the drum if it exceeds a certain unwinding speed. The apparatus incorporates a winch mechanism (16-20) by which the drum (1) can be manually turned either to raise or to lower a suspended load. The winch mechanism is associated with a braking means (21) comprising permanently contacting friction braking elements (22, 24, 25) and a one-way torque coupling (22, 28, 31-33). That coupling functions between those friction braking elements and the winch handle shaft (17). When the winch mechanism is set for use said one-way torque coupling prevents unwinding motion of the drum (1) otherwise than against the resistance of said permanently contacting friction braking elements.
