Title: Automatically assembling articles in a conveyor system
IPC: A23G7/00
Filed: 1979-12-19
Abstract: A mechanism for assembling rows of articles of different lengths ready for loading onto shelves comprises a feed conveyor (1) arranged to deliver articles to a juxtaposition assembly conveyor (2). A first photoelectric cell (PEC 1) detects the lengths of articles on the feed conveyor (1) and provides inputs to timers (T1, T2) one of which sums the lengths of the articles and resets when the sum reaches a predetermined length corresponding to the maximum capacity of a shelf, and the other of which monitors the length of each article and then resets when the article passes. A second photoelectric cell (PEC 2) is located between the conveyors, and the distance between the two cells is made just greater than the length of the longest article. The first conveyor (1) runs continuously until the sum of the articles lengths reaches said predetermined length and then it stops, provided no article is at the location of the second cell (PEC 2). The second conveyor (2) is driven when there is an article at the location of the second cell (FEC 2) until the sum of the article lengths reaches said predetermined length when it drives continuously until the lead article trips a full row stop switch. The articles thus assembled on the second conveyor (2) are then loaded onto a shelf and the full row switch is reset. The operation of the mechanism recommences, but with the roles of the timers (T1, T2) reversed so that any part length of an article already recorded is included in the next summation, such an article is held on the first conveyor (1) and then forms the lead article of the articles next assembled on the second conveyor (2). <IMAGE>

Title: Null control of multiple beam antenna
IPC: H01Q25/00
Filed: 1980-02-21
Abstract: A multibeam antenna produces a null at one or more specified points in its composite pattern with greater frequency band width for a given null depth than does the prior art. For example, a ring such as R1 of elemental beams about the null A are set to have a phase difference between adjacent beams of 360 DEG  divided by the number of beams in the ring. The amplitude of each of the beams is chosen so that each such ring set is self-nulled at the intended null and any common change in the side lobes of all beams of a ring set at the null due to frequency change is substantially equal. Thus, even with change in frequency, the null depth and position is substantially unchanged. Other phase distributions giving a similar effect are possible. <IMAGE>
