Patent EP-0051242-A1 (EP)
Inventor: DAVIS MICHAEL D
IPC: F16K11/07
Filed: 1981-10-26
Abstract: A rotary pump and flow control valve assembly (73) are disclosed. The pump includes a pumping element (17) defining fluid pockets (31), a discharge port (59) and a discharge fluid path (57). The flow control valve assembly is disposed in a valve bore (71) and includes a valve spool (83) having a spool land (105) disposed between the discharge path and a bypass bore (81). The spool-land includes a cylindrical wall portion (109) and an annular wall portion (111) extending from the spool to the cylindrical wall portion. The wall portions define an annular fluid chamber (115) in communication with the discharge path. The wall portions are relatively thin such that the cylindrical wall portion expands radially when the annular fluid chamber communicates with fluid at relatively higher fluid pressure. The result is a reduction in the normal clearance between the cylindrical wall portion and the valve bore, reducing leakage past the spool land.

Abstract: It is known to use various materials such as rags to clean the dip stick while measuring the oil level of an internal combustion engine. Often this is unsatisfactory as a rag or suitable substitute is not readily available when the checking of the oil level is desired. To alleviate this problem, the cleaning device (1) has means (20) to removably mount the device (1) at a suitable location near the engine. The device (1) has a housing (2) with a U-shaped cross-section and a layer of absorbent material (10) located on and covering an inner surface (8) of the housing (2). Part of a dip stick (22) can be laterally inserted into the housing (2) in such a manner that that part (24) is surrounded by absorbent material (10). The dip stick (22) can then be removed longitudinally to remove the excess oil.

Abstract: Disclosed is a method of preparing a clear partially hydrolyzed aluminum alkoxide solution by mixing an aluminum alkoxide with about 0.4 to about 1 moles of water per mole of aluminum alkoxide in the presence of sufficient alcohol to give a maximum weight percent of equivalent alumina of 10%. The mixture is then heated until clear, which typically requires a temperature of about 40 to about 60°C. Then sufficient additional water is added to bring the number of moles of water per mole of alkoxide up to at least about 2. The water is added in the presence of sufficient alcohol to give a maximum weight percent of equivalent alumina of about 3%. A polymerized alumina glass can be prepared from the composition by heating it to a temperature of at least 500°C.

Abstract: An electronic aid for assistance in pronunciation learning which prompts the operator to speak a chosen word (1802), compares the operator speech (1805) to the correct pronunciation of the chosen word, (1806) and generates a score (1807) representative of the comparison. Data (1802) representative of the correct pronunciation is stored and is later selectively withdrawn. An indicia representative of the selected data (e.g. the spelling of the word, numeral, or allophone) is communicated (1803) to the operator who attempts to correctly pronounce the sound. The attempt (1804) is used to generate imitation data (1805) which is compared (1806) with the correct pronunciation data so as to generate a score. This score, if it passes a threshold, is recognized (1808) as being a correct pronunciation: otherwise, the operator is preferably given instructions (1809) so as to correct his pronunciation and another attempt is made. 
     In another aspect, an entire sequence of words is communicated to the electronic learning aid by the operator and the learning aid communicates a total score representative of the pronunciation of the entire sequence to the operator. In a typical operation, the sequence of words constitutes a sentence. The operator pronounces the sentence, the apparatus recognizes the sentence by recognition of word components therein. Each word, when matched with a template generates a matching score. A functional relationship sum of the matching scores indicates the accuracy in which the operator has pronounced the entire sequence. This accuracy, together with feedback is communicated to the operator.
