Patent GB-913857-A (GB)
IPC: B41F31/06
Abstract: 913,857. Inking-apparatus. LANGSTON CO., SAMUEL M. March 29, 1961, No. 11462/61. Class 100 (2). An ink fountain for a printing machine comprises a fountain roller, a flexible blade convergging downwardly towards the side of the roller and forming therewith a trough for the ink from which the ink is withdrawn as a film or the roller surface as the roller rotates, means for closing the ends of the trough, and means for adjusting the lower edge of the blade with respect to the roller surface to regulate the thickness of the film and its axial extent, the adjusting means comprising wedging elements engaging the underside of and movable in a plane approximately parallel to the plane of the blade, and means for adjusting said elements to displace the lower edge portion of the blade with respect to the roller surface. The duct blade 42 and fountain roller 11, Fig. 4, together with end-plates, constitute an ink reservoir. The blade 42 is secured by bolts 41 to a bar 35 screwed to a bracket member 29. A second resilient blade 44 is secured beneath the bar 35 by the bolts 41 and rests on a rib 45 of the member 29. The edge portion of the blade 44 is divided by slits into a series of tongues along its length, and between each tongue and the blade 42 is a cylindrical wedge member 48 threaded on to a screw 49, rotation of which moves the member 48 inwardly or outwardly between the blade 42 and tongue 47, inward movement pressing the blade 42 with greater pressure against, or moving it nearer to, the roller 11. The ductor roller 12 is oscillated between contact with the roller 11 and a roller 13 by means of hydraulic cylinders 75, Figs. 4 and 13, controlled by a valve 144 actuated by a cam 143 rotated from the printing cylinder 18, and supplied from a pump 146. The fountain roller 11 is driven by a separate hydraulic motor 53. Rollers 13, 15 are reciprocated axially by a lever 98 oscillated on a shaft 99 by an hydraulic cylinder 103 controlled by a valve 159 itself controlled by a valve 137 actuated by pins 133, 134 engaged by arms 125, 126 moved in response to oscillation of the hub of the lever 98.

Title: Controlled heat sealing of wrappers
Inventor: OSTI ROBERTO
IPC: B65B51/16
Filed: 1992-05-08
Abstract: Single commodities (5) such as packets of cigarettes are enveloped in a thermoplastic wrapping and directed ultimately toward a heat seal station by way of a belt conveyor (2) looped around at least one pulley; each packet (5) is taken up from the belt, together with its wrapper (6), between two disks (7) disposed coaxial with and on either side of the pulley, each consisting in two concentric circular rings (8, 9) rotating as one with the pulley and thermally insulated one from the other. The two inner rings (8) are heated by resistances and positioned to engage and seal the end folds of the wrapper (6); as the seal is effected, the packet (5) encounters a diverting element (11) set between the disks and adjustable for position according to the operating speed of the wrapping machine, by which it is distanced from the centre of the pulley and thus caused to pass from the inner rings (8) to the unheated outer rings (9). The duration of heat sealing thus remains unaltered whatever that speed. <IMAGE>

Title: Monitoring system status
Inventor: PHAAL PETER
IPC: H04L12/26
Filed: 1993-10-21
Abstract: In order to monitor the status of a system in the form of a communications network, such as a computer local area network (LAN) (10) Fig. 1, (not shown) or an SS7 telecommunications signalling network, measurements are made of various operating parameters for each domain (S1...S14) or segment of the network. The measurements for each parameter are scaled in accordance with a respective piecewise-linear scaling function (300) Fig. 4, (not shown) for that parameter, so that all scaled measurements for all parameters have values in a range from 0 to 3, values of 1 and 2 corresponding to threshold values (T1 and T2) of interest. An extreme scaled value, such as the maximum or minimum value, is selected for each parameter, and plotted on a respective one of multiple radially-extending axes 301 - 306, each of which is associated with a respective parameter. The plotted values are connected to form a polygonal figure 309. Values exceeding thresholds suggest significant faults. <IMAGE>
