Title: Percarboxylic acid solutions with improved stability in contact with stainless steel
Inventor: THIELE GEORG
IPC: C07C409/00
Filed: 1996-05-09
Granted: 2009-10-27
Abstract: This invention relates to percarboxylic acid solutions, in particular aqueous equilibrium percarboxylic acid solutions, with improved stability in contact with stainless steel and to a process for the production thereof. Percarboxylic acid solutions according to the invention contain a percarboxylic acid having 1 to 12 C atoms and one or two peroxycarboxyl groups and are characterised by a content of polyphosphoric acid of the formula H n+2P n O3n+1, in which n is greater than or equal to 2.3, in a quantity of 0.2 to 10 wt.%. These solutions are distinguished in comparison with known solutions by reduced corrosive action and reduced decomposition in the presence of stainless steel. The solutions are obtainable by reacting a carboxylic acid with hydrogen peroxide in the presence of polyphosphoric acid of the above-stated type and quantity as the catalyst.

Abstract: The invention relates to a method to measure an electro-chemical activity of a non-metallic liquid layer lying on a molten bath by means of a measuring cell with an electro-chemical element which has an active part and with a counter electrode. The invention also relates to a measuring cell to measure an electro-chemical activity. In order to achieve exact measuring results of an electro-chemical activity with the least possible expenditure, the measuring cell is dipped through a non-metallic liquid layer into a molten bath, the active part of the electro-chemical element being surrounded by the non-metallic liquid layer of the material of this layer on insertion, this material being held at the electro-chemical element until after measuring the electro-chemical activity and the measurement being carried out after dipping the electro-chemical element into the molten metal within the molten bath. The electro-chemical element is especially developed to enable that the material to be measured adheres to it.

Title: Gas turbine stationary blade unit
Inventor: TADA HIROJI
IPC: F01D9/04
Filed: 1998-09-14
Granted: 2002-06-11
Abstract: Gas turbine stationary blade unit in which two stationary blades are built in a segment by shrouds is provided with object to lessen occurrence of cracks. Two stationary blades 1a, 1b are fixed respectively by outer shroud and inner shroud, each divided into two parts 2a, 2b and 3a, 3b. Flanges 4a, 4b are provided to divided end portions of the outer shrouds 2a, 2b to be jointed together by bolts via boltholes 7. Likewise, flanges 5a, 5b are provided to divided end portions of the inner shrouds 3a, 3b to be so jointed. If the two stationary blades 1a, 1b are fixed in a segment by the shrouds which are not divided, restraining force becomes larger, local stress occurs due to thermal stress and frequency of crack occurrence increases, but as the shrouds are divided respectively into two parts and jointed together by bolts, crack occurrence is lessened.  Also, pinholes are provided in face of divided portion of the shrouds and pins are inserted thereinto for connection of the divided shrouds, thereby relative movement between the divided shrouds is prevented and a strong jointed blade unit is provided.

Abstract: The bolt, in a one-way nut combination, includes a head, stem, and bolt threads on said stem. A longitudinal channel is defined on the bolt stem by a plurality of notches. The nut has threads complementary to the bolt threads and at least one compressible tine extending into a cut-out. The compressibl e tine portion has a body portion and a radially aligned distal end with a narrow mouth and wider throat. The nut is threaded on the shaft such that th e tine flexes in and out of the cut-out as if rides between the notches and threads. However, counter-rotational movement is prevented when the distal e nd of the tine is received in one of the notches. In another embodiment, the ti ne (320) is located on an insert which is mounted in the nut (310). In another embodiment, the tine is formed at one terminal end of a U-shaped or J-shaped  clip. The clip is slipped over a sheet panel to thereby form a locking nut bore.

Abstract: In a system to which a plurality of devices are connected, each device has heretofore required a connector for an AC adapter and a connector for a signal line.  Further, in order to arrange it so that the amount of power supplied to the overall system will not exceed a limit value, it has been required to adjust the amount of power during system use by turning the power source of each device on or off.  According to the present invention, a signal line for data transfer and a power line for supply of power in a system connecting a plurality of devices are consolidated in a single cable to make it possible to connect both lines to one connector of each device.  The power controller of a certain device acquires the properties of a plurality of devices connected to this device, decides the optimum power distribution and controls the power controllers of each of the other devices.
Patent CA-2261493-C (CA)

Abstract: A load clamp has two selectively openable and closable opposing clamping assemblies, one of which comprises at least a pair of clamp arms movable sepa-rately from each other toward and away from the other clamping assembly. Separate actuators for the respective clamp arms are controlled automatically by a regulator in such a way that the respective closure movements of the arms are simultaneous. A selective adjuster assembly enables the operator to select alternate different maxi-mum magnitudes of clamping force to be imposed by the clamp arms on different loads. An override assembly overrides the regulator to permit nonsimultaneous clamp arm movement, automatically in response to resistance to closure by one of the clamp arms, independently of selective variation of such adjuster assembly. Such independence is achieved by overriding the regulator automatically in delayed response to a magnitude of clamping force which is less than the different maximum magnitudes selectable by the adjuster assembly, the delay in response being sufficient to enable such different magnitudes to be attained in accordance with the operator's selection.
