Patent EP-0336711-A2 (EP)
Inventor: JOHNSON BRION
IPC: H04N5/268
Filed: 1989-04-04
Abstract: A transition interrupt for a video switcher which occurs at any point during or just prior to a transition between a program bus source and a preset bus source replaces the source on the preset bus with a new source. The program bus executes a cut or fade to black of the current source, and then the new source from the preset buss is switched to the program bus so that the new source is now on the program bus at black. The program bus is held at black, if necessary, until any necessary initial activation sequence is completed, such as preroll for a tape or cassette recorder, and then brought up from black to complete the new transition due to the transition interrupt.

Abstract: A device for detecting the degree of deterioration of bank notes has a driving rotary body (31) and a detection rotary body (33), which are a pair of oppositely disposed rollers each having alternately disposed enlarged diameter portions (31A; 33A) and annular grooves (31B; 33B). These enlarged portions and the grooves of the two rotary bodies are in staggered, opposed relationship so that when a bank note (P) is conveyed between the two rotary bodies, the note is deformed into a wave shape. The rotation of the driving rotary body (31) influences on the rotary movement of the detection rotary body (33) depending on the stiffness of the bank note in the wave shape. When the bank note is new and stiff, the influence is strong, while when the bank note is old and deteriorated with a small stiffness, the influence is small. Such influence is detected from variation in rotary movement of the detection rotary body (33) to which a predetermined rotational characteristic is given by a clutch device (39).

Abstract: A steerable beam antenna system (24) for use in satellite communication systems and including a main reflector (32) and an antenna array having a plurality of feed elements (50) is disclosed. Additional feed elements (314, 316) are positioned along with the array (116-119) and are used to cancel undesirable side lobes which appear as the beam is steered towards the end portions of a target area (324, 330). The antenna array is positionable at or near at least one focal point of the main reflector (48), and its feed elements can receive microwaves from or transmit microwaves toward the main reflector. A Butler matrix (110) having multiple input ports (310) and multiple outputs (312) is connected to the array of feed elements and substantially performs a spatial discrete Fourier transformation on a generated set of signals to be transmitted which have a predetermined phase relationship between the signals, which is necessary to create the steerable beam. The Butler matrix also can perform an inverse spatial transformation on a set of incoming signals focused on the array by the reflector and received by the feed elements.

Abstract: Information is communicated by microwave radio between transponders (9,10) carried by vehicles (7,8) travelling on a road (1) and a station (22) adjacent the road. The communications from the transponders are effected by the transponders suitably modulating their reflections of beams of microwave energy transmitted by the station from aerials (B) mounted on a gantry (11) above the road, these aerials irradiating respective communication areas (28,29,30). In order to prevent communications from different transponders overlapping and hence interfering with each other the transponders are enabled for their communications by microwave energy from further aerials (A), which energy has a higher frequency to enable it to be beamed at relatively small respective activation areas (23-27) the sizes of which are such that they can each only contain one vehicle and hence one transponder at any given time. The further aerials are activated, one at a time, successively and cyclically, so that the transponders are necessarily enabled in succession, the activation rate being, moreover, sufficient to ensure that all transponders passing through the relevant stretch of road are in fact enabled. During each interval between the activation of each further aerial and the next the station transmits a command from the aerial(s) (B) associated with the further aerial (A) which has just been activated ordering any transponder which has just been enabled to communicate its presence. If it receives such a communication the station transmits an address code from the relevant aerial(s) (B) which is stored in the relevant transponder and used subsequently to selectively address that transponder for further communication.

Abstract: Broadband terminals, such as video terminals and a video conferencing system, are directly connected to broadband digital access crossconnect systems and connections between the terminals are established via the crossconnects and DS1 or DS3 interconnecting links under control of telephone exchanges associated with the different crossconnects. A broadband terminal is connected to an associated exchange, as well as, a crossconnect and a connection from one terminal to another may be requested by transmitting a special request code to the exchange together with a directory number assigned to the desired broadband terminal. The central office, on the basis of the directory number, area code and exchange code, selects a broadband interconnecting link from the crossconnect to which the originating terminal is connected to the crossconnect to which the terminating terminal is connected. Furthermore, the originating exchange transmits the identity of the selected link and the directory number via a common channel signaling system to the exchange associated with the requested terminal. Both the originating and terminating exchanges transmit connect messages to their associated crossconnects to establish a broadband path between the two terminals.

Abstract: The burner has a radial blower with a pressure-generating chamber (31), the external walling (26) of which runs spirally. The pressure- generating chamber is essentially wider than the fan wheel (27) but, in the region of the air outlet (35), has a first blocking means in the form of a bulwark (37). The air inlet (33) to the pressure- generating chamber (31) is arranged on the periphery of this chamber and more specifically axially staggered in relation to the fan wheel (27). Between the air inlet (33) and the air outlet (35), there are second blocking means. These second blocking means (39) have a part (42) which is concentric with the fan wheel (27) and a part (43) which extends from the concentric part (42) as far as the proximity of the inner edges of the blades (41). The outlet chamber (55) has an outlet opening (57), through which combustion air can flow to the burner head. This radial blower is very compact but makes it possible to generate a relatively high pressure, as is required for burners, in which the combustion air is delivered through an air screen in order to obtain recirculation of combustion gases. By means of recirculation of the combustion gases, a relatively favourable flame temperature can be brought about, which extensively excludes the formation of nitrogen oxide. <IMAGE>
