Title: Label switching and control interface for asynchronous fast packet switching
Inventor: DEMICHELIS CARLO
IPC: H04L12/56
Filed: 1989-10-16
Abstract: ABSTRACT         A  label  switching  and  control  interface  for asynchronous fast packet switching consisting of a set of label switching and cell processing units controlled by a control unit; the units operate at each multiplex level in real  time through using microprogrammed  logic requiring control processor intervention only at connection set-up and release.    The  units  implement  low  level  flow  control algorithms to exploit the advantages of this configuration. A label becomes indicative of a virtual circuit which is allotted only locally to a cell, thus removing the necessity for  very  complex  labels,  while  the  parameters  which characterize the connection which uses a particular label are stored in the unit itself.   Each unit switches the label characterizing the connection at the node input multiplex with the label characterizing it at the output multiplex. At  the  same  time  it  associates,  with  each  cell,  the information necessary for multiplex switching which is then carried out in a self-routing network; the cells processed in this  way  by  each  unit  of  the  set  are  statistically multiplexed asynchronously and sent to a connection network termination.    This  termination  in  turn  serves  other asynchronous multiplexes,  which can operate at different frequencies. Label switching units do not have their own operating frequency, but automatically assume that of the asynchronous multiplexer to which they are connected.

Title: Laser ignition of explosives
Inventor: LOUGHRY BRUCE
IPC: F42B3/113
Filed: 1990-01-09
Abstract: Abstract of the Disclosure A system for laser-ignition of explosives or the like includes a laser system coupled to an optical fiber for conducting light energy to a window positioned at an end of the fiber remote from the laser system.  An explosive charge is contained within an initiator housing on a side of the window remote from the adjacent fiber end.  A dichroic film is positioned at the window  surface  adjacent  to  the  explosive  charge,  and  is constructed to reflect light energy within one wavelength range and transmit light energy within another wavelength range.  The laser system is controlled for selectively transmitting light energy at the one wavelength range to test continuity of the laser-fiber-initiator light path as a function of reflections from the dichroic film, and at the other wavelength range to ignite the explosive charge. In one embodiment of the invention, the dichroic film takes the form of a transparent disc having the film deposited thereon.  The disc is of flexible resilient construction, and is sandwiched within the housing between the window surface and the explosive charge.  In other embodiments of the invention, the film is formed as a coating on and integral with one of the window surfaces or on the fiber end.

Title: Method, anchoring element and device for tensioning a rod
Inventor: ISLER ERWIN
IPC: E21D21/00
Filed: 1990-01-31
Abstract: A B S T R A C T          A nut (15), for tensioning a rock-anchor-rod, has a tubular body (25) with a saw-tooth thread  (28). The body (25) of the nut  is divided, by a plurality of longitudinal slots,  into segments (31).  The said segments are connected together by cross-sectionally U-shaped resiliently flexible ribs   (26).     One  end-face  of  the nut   (15)   has  a convex-spherical   flange   (17)   which  bears   against an anchor-plate.  The slots (30) extend through the flange (17) as far as the inner wall of the ribs (26).  Between the ribs (26), the flange (17) carries radial incisions (37) extending as far as the body (25) of the nut.  As a result of this the segments  (31)  are  tangentially  resilient.    In  order  to tension the anchor-rod, the nut (15) is pushed axially onto the saw-tooth thread of the rod.   The jaws of a tensioning device engage in the thread at the free end of the rod and bear  against  the  nut  (15).   When  the  said  cheeks  apply tension to the anchor-rod, the nut  (15)  is pressed to the anchor-plate.  This ensures rapid and accurate preloading of the anchor-rod.  (Fig. 3).

Title: Construction kit for horizontally and vertically sliding window assemblies
Inventor: DALLAIRE RAYMOND
IPC: E06B3/44
Filed: 1990-03-01
Abstract: A construction kit for horizontally and vertically sliding window assemblies is provided wherein a single set of extruded profiles are used to construct either type of window. Each window has a main frame including a sill, a header and a pair of jambs which are constructed from a single hollow multi-chambered main frame extrusion. Each window also includes at least two sashes which are likewise framed by a single multi-chambered sash extrusion profile. Other features of the construction kit include snap in glazing profiles which permit the rapid and economical glazing of window panes, snap in members for supporting weather stripping and guiding window sashes to provide extra versatility in the placement of guide rails and weather stripping. A unique system for weather stripping at the meeting rails is also provided whereby a slot for holding weather stripping is provided on the rear surface of the meeting rails so that the weather stripping can be wrapped around the end of the meeting rail and secured by frictional engagement between the rear surface of the rail and the window sash. This not only provides a much faster system for weather stripping the meeting rails but also provides a much more effective barrier against the intrusion of air in the area between the ends of the meeting rails and the window sashes. An additional feature of the construction kit is the two tiered main frame extrusion which provides an extra surface along the outer edges of the window to permit installation of an additional weather stripping, thus yielding a window with superior wind resistance.
