Title: Conveyor
IPC: B41D5/00
Filed: 1962-12-19
Abstract: 987,333. Endless conveyers. J. H. W. SMITH, and D. T. R. BALDWIN. Dec. 12, 1963 [Dec. 19, 1962], No. 48013/62. Heading B8A. A conveyer system comprises a horizontal roller conveyer 10 having one or more gaps therein, at each of which an elevator 12, 13, 14, 15, 16, 17, supplies articles 1, 2, 3, 4, 5, 6, to the conveyer, each elevator being arranged and constructed to carry articles already on the conveyer 10, across the gap. Each elevator comprises a pair of parallel endless chains on belts 19 carrying therebetween cross-members 24 for pushing the articles up a slide surface 18, which may incorporate guide rails. The timing of the elevator chains are adjustable by movable idlers 22 and are driven around further idlers by a pair of drive sprockets 27. The article being pushed up the surface 18 passes over a freely rotating roller mounted on the drive-shaft between the sprockets 27 and on to the rollers 11 of the conveyer 10. Powered rollers 32, 33 on each side of the sprockets 27 assist in this transference. Further cross-members 34 are supported between the parallel chains 19, upstream of each pusher cross-member 24, and serve as a platform over the gap in the conveyer 10 after an article has been delivered. The platform is rendered horizontally in line with the rollers 11 due to the chains 19 passing over horizontally disposed sprockets 26, 27. The length of the elevator over which the crossmembers are provided is dependent upon the number of articles on the conveyer 10 following the delivered article, in any one cycle. In the example shown in Fig. 1, six elevators all feed articles to a common conveyer 10, the timing of the elevators being such that one article is delivered in front of the advancing line of articles on the conveyer 10. The platform cross-members 34 may either be in the form of rollers or non-rotational. In a further embodiment the slide surface 18 is replaced by an endless belt moving at the same speed as the chains 19.

Abstract: 1,031,980. Electric selective signalling. AMERICAN DISTRICT TELEGRAPH CO. Dec. 15, 1964 [Dec. 19, 1963], No. 51101/64. Heading G4H. In an electrical protection system of the kind comprising a protected place 11, Fig. 1 (not shown), and a central station 10 connected to it by a line 12 and having a battery 33 and current-sensitive relays B, G to detect changes of current in the line, protective devices at 11 being adapted when operated, to alter the current in the line, a second battery 40 is provided adapted to be connected to line 12 in place of battery 33 to produce reverse current, there being diodes 13, 25, 32 at 11 to prevent reverse currents unless the diode circuits have been bridged by a dummy resistive circuit or partial earths. Normally, switches S1 and S2 are in the position shown so that battery 33 applies current to the protective circuit shown diagrammatically as variable resistor 15, foil 16, switch 19, foil 20, door switch 23, resistor 24, Zener diode 25, foils 26, 27, Zener diode 13 to earth. If switch 19 is operated, e.g. for day-time use the righthand part of the circuit is shorted by Zener diode 32. The foils are lead strips on windows or doors which may be broken or earthed by an intruder. Door switch 23 causes resistor 24 to be shunted. Normally, the current is about 15 milli-amps. If a foil breaks it will drop to zero. If a foil is earthed, or if switch 23 is operated it will rise. Threshold relays B, G at the central station respond to currents below a certain level and above a certain level to give an alarm. Test.-If switches S1 and S2 are transferred, reverse polarity battery 40 is connected to line 12. If the protective circuits are intact the diodes 13 and 25 prevent the flow of current. If another path exists the flow of current operates relay Z and gives an alarm. If the protection is " off," switch 19 being transferred for day-time use of the premises, diode 32 replaces diode 25. Partial earths, resulting from deteriorating insulation, are also detected by this test. Dirty contacts &c. may be detected by applying an increased reverse voltage, e.g. from a second reverse battery, until the Zener diodes break down and conduct in the reverse direction. A dirty contact giving a high resistance then prevents a proper amount of current flowing and relay Z does not operate. In another form only the final diode 13 is provided.
