Patent EP-0316528-A2 (EP)
Inventor: ROMEO ROBERT
IPC: A47L9/00
Filed: 1988-09-01
Abstract: An upright vacuum cleaner which is convertible for floor cleaning and above the floor cleaning, has a housing (10) mounted on a floor nozzle in which a vacuum is drawn. A hose (20) extending from the housing is insertable into a conduit which leads into the floor nozzle (18) for floor cleaning. The hose also receives tools (32, 34, 36, 38, 40) for above the floor cleaning. These tools are removably held in a tool holder (44) on the rear wall of the housing with recesses and lands (50) in the wall which is flexible. The recess (52) at one end of the wall (66) is defined by a member which overlaps the wall to define a lip (74). A nozzle (40) for above the floor cleaning snaps over the lip and is held in the compartment between the wall and the end of a land (50) between the recesses (52, 58) with the mouth (46) of the nozzle behind the lip (74) and the open end of the nozzle opposite its mouth on a rib (62) on the end of that land which catches the open end of the nozzle. 
     The flexible wall can readily be depressed so as to release the nozzle when it is to be used.

Abstract: There is disclosed an improved process for the preparation of 3-[(4-bromo-2-fluorophenyl)­methyl]-3,4-dihydro-4-oxo-1-phthalazineacetic acid. The process is significantly improved over the prior art process in preparing the product in a one-step process where the prior art required three steps. The instant process directly alkylates a phthalazine ring nitrogen in the presence of the acetic acid moiety without the necessity of protecting the carboxylic acid group as was necessary in the prior art preferred process. The product is useful for treating the progressive deterioration resulting from diabetes.

Abstract: A capacitive structure (40) comprises a group of capacitive layers of equal width, each including a dielectric substrate (42) and a metallic area (44), which covers a major portion of an upper surface of the dielectric substrate (42) and which extends to one edge of the dielectric substrate (42), a mass of conductive material (70, 74) covering each edge of the layer to provide electrical connections to and between the metallic areas (44) extending to the edges. The metallized areas (44) on alternate layers extend to opposite edges. A group of at least three dielectric layers (56) of equal width, is stacked on the top of one another, and covers the group of capacitive layers. Preferably a group of at least three dielectric layers (58) of equal width, is stacked on top of one another and is beneath the group of capacitive layers. Alternate ones of the layers of each group are offset laterally so that indentations (50, 52, 60, 62, 64, 66) are formed along each edge whereby the conductive masses (70, 74) which substantially fill the indentations (50, 52, 60, 64, 66), bond the capacitive (42) and dielectric (56, 58) layers tightly to each other. Additionally, a covering tape (78) may be adhesively applied to the top.

Abstract: The invention provides a method and apparatus for the mass spectrometric determination of the isotopic composition of an element comprised in a sample by gas chromatography-isotopic ratio mass spectrometry. As a sample elutes from the column 5, it enters a sample conversion means 17 which converts the element to an analysis gas (a gas comprising the element in elemental form or in the form of a simple compound, eg N₂ or CO₂) which is admitted into the mass spectrometer 35 only during a second time interval corresponding to the elution of the peak containing the sample from column 5. One or more calibration samples of a reference gas are admitted into the spectrometer 35 during first time intervals which do not overlap the second time interval, thereby minimizing the contribution of the analysis gas to the reference gas mass analysis, and v.v. Various devices (7,12,30,41,49) are provided to minimize disturbance to the flow of gas into the spectrometer 35 during operation of the method.

Abstract: A magnetic recording and reproducing apparatus for performing automatic tracking in a video tape recorder of a helical scan type. A magnetic head is wobbled by an electromagnetically driven actuator in a transverse direction of a recording track, a tracking error signal is obtained by extracting a signal component attributable to this wobbling from a signal reproduced by the magnetic head, and the extracted signal component is fed back to the electromagnetically driven actuator. By setting the magnetic head width to 1 - 1.5 times the recording track width, a dead zone is made small, and the tracking error signal is obtained positively. In addition, by setting the frequency for driving the electromagnetically driven actuator at a level between a primary resonance frequency and a secondary resonance frequency and by subjecting the driving frequency to phase conversion, the driving frequency is converted into a high frequency to permit highly accurate tracking. Furthermore, any deviation in the tracking by a fixed magnetic head caused by a DC current and the like is prevented by extracting a low frequency component containing a DC component from the tracking error signal and by feeding back that extracted signal to a capstan motor for driving a magnetic tape.
