Abstract: Die Gleiskettenspanneinrichtung umfaßt einen Gleiskettenjustierer (34), der durch Einpressen von Fett ausgedehnt werden kann und dadurch eine zuvor eingebaute Spannfeder (32) auf eine vorbestimmte Vorspannung zusammendrückt. Der Gleiskettenjustierer (34) umfaßt ein Gleiskettenjustiergehäuse (44), in dem teleskopförmig verschiebbar ein Zylinder angeordnet ist. Während das Gleiskettenjustiergehäuse (44) unmittelbar gegen das eine Ende der Spannfeder (32) anliegt, weist der Zylinder ein Kopfteil auf, das während der Ausdehnung des Gleiskettenjustierers (34) zur Erzeugung der Federvorspannung an einem demontierbaren Anschlag (86) anliegt. Zur Arretierung der Spannfeder (32) in ihrer vorgespannten Stellung sind Vorspanndistanzstücke (96,100) vorgesehen, die das Gleiskettenjustiergehäuse (44) festlegen. Dadurch kann das zuvor eingepreßte Fett aus dem Gleiskettenjustierer (34) abgelassen werden, so daß letzterer wieder verkürzt wird, indem das Zylinderkopfteil vom Anschlag (86) weg gezogen wird und so einen Zwischenraum zwischen Gleiskettenjustierer und Anschlag schafft, damit der Gleiskettenjustierer sich später etwas ausdehnen kann, falls dies z.B. zur Kompensation einer Längung der Gleiskette aus Verschleißgründen erforderlich ist. Das Aufbringen der Vorspannung auf die Spannfeder (32) kann auch mit Hilfe einer geeigneten Druckvorrichtung durchgeführt werden, die nach dem Ausbau des genannten Anschlags (86) zwischen den den Anschlag sonst tragenden Querrahmen (85) und den Gleiskettenjustierer (34) eingesetzt wird.

Abstract: A multifilament lamp combination (12' or 121) is disclosed which may be used alone and in multilamp arrangements with other single and multifilaments lamps (12' or 121) to provide pattern size variation from a large diameter flood effect to a smaller diameter spot effect. A spot/flood capability exists to provide large pattern exposure simultaneously with secondary spotlighting. The filaments (15 and 16: or 123, 124, and 125) can be energized selectively from a remote switching station (D) so that the individuals who are scrubbed and gloved need not touch any part of the switching arrangement (D) to change the lamp pattern size. A cluster of lights (111 through 113) can contain one or more multifilament lamps (121) within the cluster, so that by switching on the rear most filament (123) of the multifilament lamps (121) and switching off the single filament lamp, a small high intensity pattern is obtained by switching to the other filaments, a large pattern of high intensity is formed. More than two filaments can be provided in each lamp (12' or 121

Abstract: A circuit for controlling the energization of an electrical load from an AC source. The circuit has a pair of DC lines, and means is provided for rectifying theAC output of the source to apply a DC voltage across the DC lines in the form of a full wave rectified sinusoidal signal. Signal switching means for connection between the DC lines and the load establishes a conductive path therebetween during a variable time interval when the voltage applied by the full wave rectified sinusoidal signal exceeds the voltage across the load, and means including the switching means is provided for chopping the full wave rectified sinusoidal signal to apply pulses to the load during the variable time interval at a frequency which is high with respect to the frequency of the signal. Means connected to the chopping means for modulating the width of the pulses is responsive to an externally derived signal representative of the desired operation of the load, and means is responsive to the load current for modifying the externally derived signal to maintain the amplitude of the load current below a predetermined level whereby a high power factor is presented to the AC source during a predetermined range of operation of the load.

Abstract: The disclosure relates to an air pressure sensor for use particularly in a batched counting apparatus for counting sheets or signatures in a "shingled" stream and comprising an air passage (21) terminating in a probe (17) having an orifice (19) to ride over the surface of the "shingled" stream of sheets. The jet (26, 27) delivers air from a supply line into the passage and branch passage (28) located adjacent the jet contains a floating element (31) which moves up and down the passage in accordance with static air pressure in the passage. The element is arranged to make or break a beam in a photo-electric cell arrangement (12) to operate a counting device. As the probe rides from one sheet or signature to the next, the air pressure in the passage (21) drops and the result in the fall in pressure in the branch passage causes the element (31) to fall thereby triggering the photo-electric cell to operate the counting device. The sensor is extremely sensitive, responding when passing from sheet to sheet of very thin paper and it is capable of operating at high speed.
