Patent EP-0038384-A1 (EP)
Inventor: WASHBURN WILLIAM J
IPC: F41A9/30
Filed: 1980-04-11
Abstract: A twin-barrel machine gun has two stationary firing chambers (16,18), a conveyor (26), and a feed system (20) mounted within a housing. The feed system 20 transfers ammunition (22) from the conveyor 26 to the firing chambers 116,18). The feed system (22) includes a sprocket (48) pivotably mounted about its central longitudinal axis. The sprocket (48) has two receptacle slots (50,52) and two discharge slots (62,64) circumferentially spaced thereabout. The sprocket (48) is rotatable between a first and second position. The receptacle slots (50,52) each have a first position aligned with the conveyor to receive a round of ammunition and a second position aligned with a respective firing chamber. One receptacle slot is in its first position when the other is in its second position. The discharge slots also have a first position aligned with a firing chamber and a second position aligned with an outlet in the housing. One discharge slot is in its first position when the other is in its second position. An ejector cam (84) is also rotatably mounted about an axis aligned with the axis of rotation of the sprocket (48). The ejector cam is fitted within a central hollow of the sprocket. A drive gear (78,80,126,128,116,118) connected to the sprocket oscillates the sprocket between its first and second positions and a second drive gear (100,102,90,112,114,116,118) oscillates the ejector cam (84) so that it laterally passes through the first and second discharge slots when in their respective second positions. The ejector cam ejects any cartridges from the discharge slot as it passes therethrough.

Abstract: An arrangement for covering at least part of an elongate object, for example a pipe, comprises a heat recoverable closure sheet 21 which can be wrapped around the substrate, a patch 13 and a layer of adhesive for securing the edge portions of the sheet together so that the sheet can be recovered about the substrate by the application of heat. Certain properties of the patch for example its modulus and elongation, and of the adhesive, for example its lap shear strength, are chosen so that at least part of the patch 13 will be stretched by at least 5% in the recovery direction of the sheet so that the sheet will not slip away from the patch when it is recovered.

Abstract: Der Regner für die Bewässerung von großen Flächen weist neben einem ortsfesten Lagerteil (1) für das Sprührohr (12) eine gesonderte Bremseinrichtung (3) auf. Die Bremseinrichtung (3) weist mit dem Sprührohr (12) drehfest verbundene radiale Fortsätze (13) auf. Diese radialen Fortsätze (13) werden in der Bremseinrichtung (3) durch ein hochviskoses Medium an der freien Rotation gehindert, sodaß sich die gewünschte Bremsung ergibt. Die radialen Fortsätze (13), welche drehschlüssig mit dem Sprührohr (12) verbunden sind, können hiebei mit radialen Fortsätzen (10), welche drehfest mit dem ortsfesten Gehäuse (2) der Bremseinrichtung (3) verbunden sind, kämmen, sodaß sich zwischen benachbarten radialen Fortsätzen (10, 13), welche abwechselnd drehfest mit dem Sprührohr (12) und drehfest mit dem Gehäuse (2) verbunden sind, eine Scherbeanspruchung des viskosen Mediums ergibt. Mit den radialen Fortsätzen können zur Verbesserung der Bremswirkung auch noch axiale Fortsätze verbunden sein, welche miteinander kämmen.

Abstract: The invention relates to a process for cropping the head of self-luminous rolled material, especially metal strips when it passes a rolling train. A line scanning camera is used for detecting the shape of the head by repeatedly generating optical images of the rolled material immediately downstream of the last roughing stand. The distance separating the cutting line from the beginning of the head is determined in accordance with the shape of the head. Immediately upstream a pair of shears the velocity and the beginning of the head are detected. A control signal for the shears is generated in accordance with the signals for the beginning of the head and for its velocity and with the distance of the cutting line from the beginning of the head. In order to detect the edges of the rolled material from the beginning of measurement even under wide variations of the radiation intensity the exposure time of the line scanning camera is controlled by a radiation-intensity measuring device in the sense of obtaining an optimum exposure in respect of the edges of the rolled material.
