Patent EP-0044072-A1 (EP)
Inventor: WILKINSON RICHARD L
IPC: G11B7/08
Filed: 1981-07-13
Abstract: A control system for maintaining focus of a radiant recording or writing beam, with respect to a recording surface, by measurement of the duty cycle of an informationcarrying signal recorded from the surface immediately after recording. The system includes a photodetector for detecting a beam used to recover the information, a focusing lens to focus the beams, a dither oscillator to generate a signal employed to move the lens, a duty cycle detector to provide a signal indicative of the information-carrying signal and a multiplier for comparing the phases of the two signals, and thereby providing a correction signal indicative of the magnitude and polarity focus error. This control system provides fine focus control, and is utilized in conjunction with a coarse focus control for the movable lens. In addition, the signal form the duty cycle detector can be coupled to maintain the power of the writing beam at an optimum level and the duty cycle at a constant level, such as fifty percent.

Abstract: The device has one or a plurality of keys (2, 3, 16) for imputting the coded signal and electronic circuits for the storage of the code and utilization of the signal, and for the unlocking in the case of matching the decoded signal with the stored signal. The device comprises a voltage monitor (13, 30) which triggers or prepares the unlocking if the supply voltage goes below a predetermined value and give an indication of this fact. The different functions may be performed by separate components or by a micro-computer (15). The voltage is controlled after each operation of the locking mechanism and also at predetermined time intervals. Such a device is particularly appropriate to be fitted on suitcases and brief-cases.

Abstract: A method is provided for reducing ammonia volatilization from ammoniated fertilizers and urea-containing fertilizers present on or at the soil surface after 24-48 hours following surface application. The fertilizer is applied in the presence of a water soluble compound that (a) has a saturated solution pH of about 5.0 to about 8.0 and (b) in a hydrolyzing system with the soil and the fertilizer, will form carbonates having a solubility below about 10 -10  grams per liter. The amount of the water soluble compound is that which is sufficient to suppress the formation of hydroxyl ions that otherwise would be produced in the soil according to the reaction
     with Y = calcium or magnesium.

Abstract: A continuous coater of the type having a conveyor extending through a coating booth (11) where paint or other material is sprayed onto the products as they are conveyed through the booth. The booth (11) has an air flow control vestibule (12, 13) located adjacent the entrance and exit ports. Each vestibule (12,13) is connected to an airflow exhaust system (15, 16) and is so configured that it is operative to draw air (65) almost exclusively from outside the booth into the exhaust system so that there is a minimum of input air to the exhaust system from within the booth. The incoming air from outside the booth effectively forms a flow barrier to the egress of sprayed material and/or solvent to the atmosphere through the vestibul entrance and exit ports. Preferably, there is located in each vestibule means for creating an air curtain (108) which functions to minimize the egress of paint or solvent from the coater cabinet and to provide a more nearly saturated atmosphere inside the cabinet.

Abstract: The present invention relates to a solution polymerization process for the preparation of high molecular weight polymers of a-olefins selected from the group consisting of homopolymers of ethylene and copolymers of ethylene and C 3 -C 12  a-olefins. The process comprises feeding monomer, coordination catalyst and inert hydrocarbon solvent to a reactor, polymerizing the monomer at a temperature in the range of, in particular, 105-320 °C and a pressure of less than 24 MPa and deactivating the catalyst in the solution so obtained by admixing therewith a solution of a salt of an alkaline earth metal or zinc and an aliphatic monocarboxylic acid dissolved in hydrocarbon solvent. The hydrocarbon solvent is then separated from the resultant solution and a composition comprising high molecular weight polymer is recovered. Any catalyst residues remain with the polymer. In a preferred embodiment the catalyst contains vanadium. A particular salt is the salt of a C, aliphatic acid, especially calcium 2-ethyl hexanoate.

Abstract: Bei einem Verfahren zur Dickenkontrolle bzw. -messung von Schichten, bei dem man ein anhaltendes, frequenzmoduliertes Ultraschallsignal einschallt, das periodisch ein Frequenzband überstreicht und das resultierende Signal auswertet, wird das Frequenzband so breit gewählt, daß ein Mehrfaches des Interferenzabstandes umfaßt wird. Die im Frequenzspektrum des Empfangssignals periodisch auftretenden spektralen Maxima oder Minima werden ausgewertet. Bei festgelegter Modulationsrate des Sendesignals ergibt sich eine eindeutige Zuordnung zwischen der Wiederholfrequenz der Maxima oder Minima im Spektrum und der Dicke zu prüfenden Schicht. Dabei nimmt die Wiederholfrequenz mit wachsender Schichtdicke zu. Nach einem alternativen Vorschlag wird ein der Schichtdicke entsprechendes Oberwellenverhältnis ausgewertet. Die Oberwellen entstehen dadurch, daß das Frequenzband schmal gewählt wird, so daß nur ein Teilbereich des Interferenzabstandes umfaßt wird. Die Wiederholfrequenz der Modulation wird in Abhängigkeit von dem gewünschten Meßbereich festgelegt.

Abstract: A compressor adapted for capacity control includes a rotor (16) mounting thereon vanes (14) slidably, a cylinder (11) receiving therein in the rotor (16) and the vanes (14). side plates secured to the opposite sides of the cylinder, a vane chamber (12,13) defined by the vane (14). rotor (16) and the cylinder (11) and closed at its sides by the side plates, suction ports (17) and a discharge port (19). Suction loss produced when the pressure within the vane chamber becomes below the pressure of the refrigerant supply source during suction stroke is utilized for suppressing the refrigerating capacity of the compressor at high speed operation. With the arrangement of the compressor, the effective area of the flow passage leading to the vane chamber from the suction ports varies in at least two stages such that it becomes smaller in the latter half of suction stroke than in the former half thereof. Thus. in the compressor, driving torque can be reduced at low speed operation and adequate effects of capacity control can be obtained at high speed operation.

Abstract: A method and apparatus for switching the relative position between roving bobbins held by bobbin hangers of a front row and the roving bobbins held by the rear row in a spinning frame. The roving bobbin exchange operation is carried out as successive unit operations from one end-said of the spinning frame to the other end-side thereof. In each unit operation, first the axial distance (ab) between a bobbin hanger of the front row (15B) and a bobbin hanger of the rear row (15c), which are positioned adjacently in the lengthwise direction of the spinning frame, is reduced to a predetermined distance, (cd) then the relative position of those two bobbin hangers is reversely changed while maintaining the reduced axial distance. Thereafter, the axial distance between those two bobbin hangers is returned to the initial condition for carrying out the spinning operation. The roving bobbin exchange operation can be carried out during the normal spinning operation, when the roving bobbins held by either one of the bobbin hangers of the front row and the rear row become substantially exhausted.
