Title: Pulp alkali addition process for high consistency oxygen delignification
Inventor: GRIGGS BRUCE F
IPC: D21C9/18
Filed: 1991-04-18
Granted: 1996-08-27
Abstract: Unbleached pulp is combined with an aqueous alkaline solution while in a state of low consistency to distribute a first amount of alkaline material sub-stantially uniformly throughout the pulp.  The consistency of the pulp is then increased to above about 18%, and the high consistency alkali containing pulp is then treated with oxygen to effect delignification.  The total amount of alkaline material applied to the pulp is between 0.8 and 7% by weight of oven dry pulp.  High strength, low lignin pulps are subsequently formed which may be further bleached to high brightness with reduced amounts of chemicals.
Patent CA-2072240-C (CA)
Inventor: SKALSKI CLEMENT A
IPC: B66B1/44
Filed: 1992-06-24
Granted: 1998-05-05
Abstract: A  semi-active   secondary  suspension comprises  a  relatively  large  actuator  for  handling low-frequency  forces  such  as  those caused  by  uneven passenger distribution, etc., by means, for example, of a position control  loop.  A pair of such suspensions on opposite sides of the car or rail can be made to act in concert, for example, by actuating only one at a time. An inner loop can be added to the position control for each secondary suspension to restore its actuator to a selected preload position when not being used as an actuator. The semi-active secondary suspension is made fully active by adding a relatively small actuator for handling higher frequency dynamic forces. A roller guide embodiment has rollers pivotally mounted on links which are spring-biased toward the rail blades. The relatively large actuators are connected to the  link springs  to  slowly  increase  or decrease the preload force on the spring acting on the links to counter low frequency disturbances. The relatively small actuators also act on the links to ensure that high frequency  disturbances are  quickly  countered  thereby ensuring a substantially vibration-free ride. Suspensions comprising slide guides, electromagnets, etc. are shown.

Title: Chuted, growable packet switching arrangement
Inventor: CLOONAN THOMAS JAY
IPC: H04L12/56
Filed: 1993-07-07
Granted: 1999-09-28
Abstract: A growable packet switching arrangement where the distribution network blocking probability is substantially reduced because the network has both switch links and chute links, and the network nodes include both a switching means interconnecting successive stage switch links and a plurality of non-switching, chute connection means interconnecting successive stage chute links. A network node can transfer a packet, being received on a switch link, to any selected one of the chute connection means of that node for transmission on a chute link. The network nodes are relatively simple and inexpensive because they store only the first few bits needed to route an ATM cell. The blocking probability is further reduced when the number of chutes per node is increased. The number of chutes may be based, for example, on the number of switch link inputs per node.

The sheets (1, 2) of silicate glass have undergone thermal tempering, but their tempering is comparatively more gentle than that of a tempered safety glass such and with the result that the tensile stresses at the centre of the glass sheets, for a thickness of these glass sheets of 1.5 mm, are from 25 to 57 N/mm<2> and, for a thickness of 3 mm, from 17.5 to 47 N/mm<2>. The degrees of tempering in the marginal region are preferably greater than in the central region of the glass sheets. <IMAGE>

Title: Asynchronous transfer mode (atm) switch fabric
Inventor: PASHAN MARK ALLEN
IPC: H04L12/56
Filed: 1993-12-14
Granted: 1999-06-15
Abstract: In an asynchronous transfer mode (ATM) switching arrangement buffer memory capacity is effectively and efficiently increased by employing a plurality of circuit cards including a master circuit card and a plurality of so-called slave circuit cards including additional buffer memory and an internal cell format in which all of the ATM cell routing information is supplied directly to the master circuit card. Then, the master circuit card utilizes the ATM cell routing information to control writing and reading of data to and from its buffer memory locations and the buffer memory locations of each of the plurality of slave circuit cards. This control of the plurality of slave circuit cards requires only unidirectional communications links to pass the control information from the master circuit card to the slave circuit cards.

Abstract: A shipping/display container that may be opened without having to use a knife or other sharp instrument, and a blank for forming such a container. The container blank includes a plurality of side panels foldably connected together in a longitudinal series, and a connecting flap foldably connected to a first end of the side panels.

To form the container, the connecting flap is connected to the second end of the side panels, forming the side panels into a continuous side wall for the container; and as this is done, the notch in the connecting flap is positioned over the end portion of the line of weakness.      To open the container, the container is severed along the line of weakness to separate the container into a top section and a bottom tray section, and the top section of the container is removed to expose the interior of the container.

Abstract: A run-flat tire the weight, space and convenience advantages of which can be substantial.  This is especially true for the urban-economy car or family type vehicles which have limited space available for a spare tire and inadequate space for the removed flat tire.  These vehicles also have higher comfort requirements that must be addressed.  The mini-space solution to the flat tire problem has very limited performance capabilities.   Other solutions include major modifications in the rim and/or the tire, which are not cost effective or compatible with a conversion to standard tires on the same rims.   The run-flat tire of this invention includes thickened sidewall portions, a belt package with a cap ply, lower sidewall rubber support portions, a specially designed bead seat area with a rim seat ply and three carcass layers.   The classical problems of inflated vs. deflated performance  tradeoffs  in  ride  comfort,  handling,  radial stiffness  and  endurance  of  the  tire  are  substantially improved.  This is accomplished with a run-flat tire having relatively small weight increases over a standard tire and a rim that can be used interchangeably with the standard tire. The run-flat tire system of this invention is capable of maximum lateral accelerations under nominal operations of approximately 0.90 gS and extended operating efficiency (i.e., handling  and  durability)  at  higher  speeds  for  longer distances.
