Title: Combined synthesis and demodulation device for a receiver of frequency-modulated waves, and receiver comprising it
Inventor: DUTASTA REMI
IPC: H04B1/16
Filed: 1981-04-16
Granted: 1984-05-10
Abstract: A combined phase-locked loop frequency demodulator and frequency synthesizer for frequency-modulated wave receivers using two phase-locked loops respectively for synthesis and for demodulation. In this device, the frequency-modulated signal is applied to one of the inputs of a first phase comparator whose other input is coupled to the output of a voltage-controlled oscillator, which output is also coupled, through a prescaler and a programmable frequency divider mounted in cascade, to one of the inputs of a second phase and frequency comparator whose other input is coupled to the output of a crystal-controlled reference oscillator. The output of the first comparator is coupled by means of a first low-pass or bandpass filter to a first input of an analog adder whose second input is coupled by means of a second low-pass filter, having a relatively low upper cut-off frequency, to the output of the second comparator. The output of the adder which combines the signals from the two filters is connected to the frequency-control input of the voltage-controlled oscillator. The output of the first filter supplies the demodulated signal and thus constitutes the output of the frequency demodulator, whose phase-locked loop is combined with the phase-locked loop of the frequency synthesizer, which selects the frequency of the modulated carrier wave, by means of the adder and the single voltage-controlled oscillator which are the common elements of both phase-locked loops.

Title: Lightbulb socket
Inventor: JUNTTI LARS
IPC: H01R33/22
Filed: 1982-10-08
Granted: 1986-07-03
Abstract: A lightbulb socket includes first and second contact members for electrically connecting two conductors and the central and side electrodes on the base of a bulb, and a threaded element for receiving the base of the bulb. The threaded element is held by spring action in a first position in relation to a shell of the socket when the bulb is unscrewed from the threaded element and is movable to a second position in relation to the shell against the spring action when the bulb is screwed into the threaded element. Coupling elements are arranged between the conductors and the contact members to break the contact therebetween when the threaded element is in its first position and to close the circuit to the bulb when the threaded element is brought to its second position. The coupling elements also serve as springs for moving the threaded element to its first position.

Title: Ink duct for printing machines
Inventor: CAPPEL BERT
IPC: B41F31/02

Granted: 1986-02-06
Abstract: An ink fountain for a printing press has a temperature-responsive element for compensating the adjustment of the spacing between the blade and the fountain roller to keep the thickness of the ink film fed by the blade substantially constant even under extreme temperature variations. The sub-frame of the ink fountain is pivotally mounted to the main frame of the printing press about a pivot axis generally parallel to the axis of the fountain roller, and the pivot angle is a function of the thermal expansion of the temperature-responsive element. In one preferred embodiment, the temperature-responsive element is elongated, received in a guide fixed to the sub-frame, and has a free end bearing against the bearing bushing of the fountain roller. In another embodiment, the temperature-responsive element is a side wall of the ink trough or is a plate parallel to the side wall of the ink trough, and rollers are journaled to the temperature-responsive element and bear against the surface of the fountain roller. In either embodiment, the temperature-responsive element is pre-stressed by a pull rod tending to pivot the sub-frame so that the temperature-responsive element bears against the sub-frame and the main frame.

Abstract: An improved process is disclosed for making an integrated circuit structure wherein a trench is etched into one or more layers to electrically separate one of the devices in the integrated circuit structure from other portions thereof by first patterning silicon dioxide and silicon nitride layer on a layer of silicon. The improvement comprises isotropically etching the silicon layer to provide an enlarged shallow etch area undercutting the patterned silicon dioxide and silicon nitride layers. Subsequent deeper anisotropic etching to form the trench will result in a trench having an enlarged upper width which, in turn, prevents the formation of voids adjacent the upper portion of the trench during subsequent oxidation and polysilicon deposition steps. Possible creation of openings to such voids in the polysilicon during subsequent planarization is thereby eliminated thus avoiding undesirable oxidation of such voids and undesirable stress formation therefrom.

Abstract: An intersection computer, for determining points of intersection of two linear functions dependent on the same independent variable, comprises a series of cells (a...n). Each cell includes a first store (A) for storing a difference in value of the two functions for a given value of the independent variable, a second store (B) for storing a difference in incremental value of the independent variable, within which a point of intersection is expected, comparison means (C) for comparing the polarity of the values in the two stores, a latch (D) for storing the result of the comparison and for supplying a signal to an accumulating means for determining the value of the independent variable at the intersection point and also to an arithmetic circuit (E) for adding or differencing the values in the two stores. The arithmetic circuit (E) and second store (B) supply values to first and second stores of a next cell, after the value from the second store has been halved relative to the result produced by the arithmetic circuit for example by means of a divider (G) interposed between the second stores (B) of the present and next cells. The value accumulated from the polarity comparisons in each of the series of cells (a...n) provides the value of the independent variable at the intersection point.

Abstract: In a butterfly valve for large cross-section lines, having a housing and a butterfly arranged such that it can pivot therein, in the region between the housing and the butterfly, there are arranged in the edge region of the butterfly in each case two seals running approximately parallel to one another, servo air being introduced into the space resulting between them. While, in the case of the prior art, the servo air inlet is produced by channels arranged in the housing in an annular manner around the butterfly flap, which is disadvantageous, according to the invention the servo air inlet is produced in the space between the seals and the housing by a small number of valves which are arranged such that they are freely accessible on the housing so that it is no longer necessary to arrange servo air channels in the housing. <IMAGE>

Abstract: High levels of immunity are achieved in chickens inoculated intramuscularly or orally with E.acervulina extract immunogens. These extracts contain at least 20 polypeptides which induce a pro­tective immune response not only against E.acervulina but also against E.tenella and E.maxima. The resulting immunity prevents intestinal lesions and reduces the number of viable oocysts in vaccinated and challenged birds. One or more of these poly­peptides can be used as an immunogen to protect against coccidiosis.

Abstract: A method and an apparatus for separating bodies from a liquid in which the liquid is passed through a filter and the bodies to be separated are accumulated on the filter. The filter forms an upper bounding limit of a space therebeneath which is alternately subjected to pressure and vacuum relative to the ambient region above the filter. This is achieved according to one embodiment by producing a reciprocal movement of the filter in the form of an oscillating or pendular movement. The pressurization in the space produces separation of the bodies accumulated on the upper surface of the filter to facilitate their discharge from the filter. The separated bodies can be assisted for discharge by mechanical elements and/or by producing wave motion in the liquid.
