Patent EP-0155489-A2 (EP)
Inventor: LOBSINGER JAMES ROSS
IPC: H03J7/04
Filed: 1985-02-08
Abstract: A digital automatic frequency control for a pulse-type radar receiver having a voltage controlled local oscillator. A first digital number is generated and converted to a first analog voltage for coarse control of the local oscillator frequency (44) (46). The first digital number is varied during the time output from the radar transmitter is present at the receiver mixer (43) causing sweep of the local oscillator frequency. When the difference frequency output from the mixer is at a value to cause output from the receiver intermediate frequency amplifier of a predetermined level (52), variation of the first digital number is halted (53), providing a coarsely tuned local oscillator frequency. A second digital number is then generated, converted to a second analog voltage which is combined with the first analog voltage (43) (61). The second digital number is vaned to cause the local oscillator frequency to be sidestepped above and below the coarsely tuned frequency (43). Samples of the receiver output are separately accumulated for sidesteps above and below the coarsely tuned frequency (54) The difference between the separately accumulated outputs is used to generate a third digital number which is converted to a third analog voltage (62) (63) (61). The third analog voltage is combined with the first analog voltage to fine tune the local oscillator frequency (50) (51).

Abstract: A method of manufacturing a refrigerator having an inner wall and an outer wall (2) which together define an interspace and cooling air ducts (17) which are at least partially embedded in the thermal insulation (30) generated in-situ in the interspace between the two walls. 
     To avoid penetration of insulating material in the ducts via gaps between the ends of the ducts and the wall during the foaming operation, the ducts are formed initially with closed ends (A) by blow-moulding from a plastics material and are fitted to the refrigerator inner wall with the closed ends protruding through apertures in the inner wall, said ends subsequently being removed after the forming of the thermal insulation.

Abstract: The method and machine are concerned with tying rotobales of fibrous matter such as hay, straw, fodder etc. The method involves cutting off the supply of fibrous matter when a bale (1) is finished while continuing to cause it to rotate. At the same time, the cord (3) is introduced into the interior of the bale-forming chamber (8) using a cord feeder (11) moving along a line parallel to the axis of the bale (1) so as to wind each cord (3) helically around the bale (1). Each feeder (11) is stopped at the end of a run, while letting the bale make at least one turn inside the bale-forming chamber (8) so as to have at least two superimposed turns of cord (3) wound around the bale (1). The superimposed turns are joined together before cutting each cord (3). In a preferred method of operation, the superimposed turns of cord (3) are joined together by stapling using a stapler (13). <IMAGE>

Abstract: The liquid crystal display unit 1, has a video signal receiver 2 and a store 3. Time-modulation grey-scale addressing of the ferroelectric liquid crystal pixels in a display panel 4 is provided to a store 10 which records the number of changes of state for each pixel during one picture-signal. Once the most-significent bit has been processed and is being displayed on the panel 4, the change-of-state store 10 has the net number of changes which the pixel has undergone in that picture. Controller 11 causes store 10 to output the value appropriate to that pixel and pass it to driver unit 9 to produce a compensating pulse (whether positive, negative or zero) necessary to ensure that there is no net electrical potential over the entire picture interval. The display produced by the compensating pulse is cleared immediately the first data of the next picture is input to the pixel. Assuming that the LSB of the data for a pixel already on display in panel 4, then in the next scan extractor 6 passes the next LSB to comparator 7 whose other input is connected to a pixel-state store 8. Accordingly, the new bit-value is compared with the existing state of the pixel, and comparator 7 passes on an instructing signal to pixel driver unit 9 only if the state of the pixel requires changing; in such an eventuality, the driver unit 9 issues an appropriate monopulse select voltage. Comparator 7 also passes such an instructing signal.

Abstract: A pressure infusion device for medical applications for applying pressure to a sealed bag of liquid (13), such as an I.V. bag, in which the pressure gauge (40) is fastened directly in the pressure applying bag (12) which presses against the I.V. bag. The gauge has a movable plunger (46) which moves outwardly from the bag by an amount depending upon the pressure within the bag. The pressure infusion arrangement is designed to be relatively inexpensive so that it can be discarded after being used. There are two forms, one in which the I.V. bag is held against the pressure applying bag by a mesh (11) which is secured to a fabric to form a pocket for the I.V. bag and the pressure applying bag. In the other form, the mesh (66) is secured directly to the edge of the pressure applying bag.

Abstract: A chemical reactor has two chambers (1,3) separated by a partition wall (5), a porous heat radiating body (2) being disposed in one of the chambers (1) and a porous heat-receiving body (4) being disposed in the other chamber (3). The heat-receiving body (4) is divided into three layers (4a,4b,4c) in the direction of flow of the raw gas mixture through it and the porosity of the layers increases in the direction of flow of the gas. The resultant differential ability to absorb the radiant heat means that there is a substantially linear temperature differential through the heat-receiving body whereby the catalyst material dispersed in it can operate effectively substantially throughout its entire volume.

Abstract: The disclosed means for coupling an optical fiber (52) and an opto-electronic device (e.g., LED, laser, or photodetector) (40) comprises a first body (10) having two substantially parallel major surfaces, with a recessed portion (a "well") (11) formed in one surface, and a through-aperture extending from the other surface to the well. Conductive means (21, 24) extend from the former surface onto the bottom of the well, and the opto-electronic device typically is mounted in the well such that the device does not protrude above the plane of the associated surface, such that the electrical contact is established between the device and the conductive means, and such that the active region of the device is centered upon the through-aperture. The first body is advantageously produced from a (100) Si wafer by means of standard Si processing techniques, including selective etching. The assembly can be mounted on a substrate, e.g., a Si wafer with appropriate metallization thereon, and the end of an optical fiber inserted into the through-aperture and secured to the first body. The assembly can be operated at relatively high speed, due to its relatively low parasitic capacitance and inductance, and can be mounted on the substrate in substantially the same was as IC chips are mounted, in close proximity to associated electrical components.

Abstract: The invention relates to a transition between stripline transmission lines that is efficient at microwave frequencies and readily fabricated, and which may be used to achieve cross-overs in stripline circuits. 
     The transition includes a coaxial section formed between pads (20-22) at the ends of the stripline conductors (C1,C2). The coaxial section is formed by a resilient center conductor (23,24) surrounded by an incomplete circle of pins (25) connected to the ground planes (G1-G4) and forming the outer conductor. In another form an incomplete conductive cylinder with parallel tabs extending from it at both ends is used instead of the circle of pins. The connections to the pads enter the ends of the coaxial section at the azimuth of the gap in the cylinder or circle of pins. Good high frequency performance despite the discontinuity between the pads and coaxial center conductor is achieved by increasing the characteristic impedance of the coaxial section and that of the stripline near the transition relative to the characteristic impedance of the stripline remote from the transition.
