Patent CA-2145818-C (CA)
Inventor: ORIARAN T PHILIPS
IPC: D21H21/22
Filed: 1995-03-29
Granted: 2008-03-18
Abstract: A one-ply paper tissue product and a method of making a one-ply paper product combining high strength and softness along with low sidedness. The paper tissue product exhibits a sidedness parameter of less than 0.3 preferably, less than 0.225, a tensile modulus of no more than 32 grams/percent strain, a GM MMD of no more than about 0.225, and a cross directional strength of at least 200 grams per 3 inches. In stratification tissues, these properties are obtained by control of stratification, particularly, chemical stratification and stratification of furnish when appropriate. The tissue has a sidedness parameter value of less than 0.3, preferably, about 0.15 to about less than 0.225. In homogenous tissue, these properties are obtained by adding a strength enhancing agent to separate furnish sources prior to the funish sources being combined, and further, optionally adding the softener to the nascent web.

Title: Hybrid equalizer arrangement for use in data communications equipment
Inventor: WANG JIN-DER
IPC: H04B3/04
Filed: 1995-09-13
Granted: 1999-09-07
Abstract: A hybrid type of decision feedback equalizer (DFE) structure that approaches optimal DFE performance is described. The hybrid DFE includes both an intersymbol interference DFE (ISI-DFE) and a noise predictive DFE (NP-DFE). In particular, an adaptive feedforward filter section is followed by both an intersymbol interference (ISI) predictive filter and a noise predictive (NP) filter. The corresponding transmitter uses a precoder that utilizes optimal coefficient values, denoted as C(z), of the hybrid DFE structure. In particular, C(z) is equal to (I + I(z)) (I + N(z)) - 1, where, the notation I(z) and N(z), as known in the art, represent the resulting coefficient values after adaptation of the ISI-DFE and the NP-DFE, respectively.

Title: Minimizing service disruptions in handling call request messages where new message formats are needed in a telecommunication network
Inventor: BAIRD MICHAEL HAMILTON
IPC: H04M7/00
Filed: 1996-02-29
Granted: 1999-09-28
Abstract: MINIMIZING SERVICE DISRUPTIONS IN HANDLING       CALL REQUEST MESSAGES WHERE NEW MESSAGE FORMATS          ARE NEEDED IN A TELECOMMUNICATION NETWORK    A signaling control point (SCP) node operates under the control of computer program instructions which interpret message instructions generated by a service administrator. The message instructions provide a hierarchical command structure which permits the SCP node to generate network messages having formats not previously defined as well as changing user specified data.  Such network messages are transmitted by the SCP node to identified switches in a telecommunication network in order to determine how a call request, such as an incoming "800" call, will be handled and/or routed by the telecommunication network.

Title: Process and apparatus for manufacturing granular material
Inventor: KNAPICK EDWARD G
IPC: C05G3/80
Filed: 1994-08-26
Granted: 1999-12-14
Abstract: In a process for making a granular material from a reject stream from a coated grade waste paper pulp stock recycling process, the pulp stock is screened so that the reject stream passes through a screen and long fibers are retained for use in making paper. Solid material in the reject stream is separated by flotation (18). Water is removed from the reject stream to increase its consistency to that of modeling clay (40). The reject stream is supplied to an agglomerator (46) which forms uniform granules of irregular but approximately spherical shape. The granules are then dried (50) so that the granules have a solids content greater than 95 %. Apparatus for performing the process and characteristics of granular material ? by the process and apparatus are also described.

Title: Cascaded surface wave device filters
Inventor: DAI JI-DONG
IPC: H03H9/25
Filed: 1996-06-06
Granted: 2001-11-20
Abstract: A cascaded surface wave device filter comprises two 2-pole surface wave device filters connected in cascade. The 2-pole filters each provide a balun function between balanced and unbalanced signal connections, and have either their unbalanced or their balanced signal connections interconnected in the cascade to reduce electro-magnetic feedthrough and improve spurious mode suppression. The 2-pole filters are conveniently longitudinally coupled double mode surface wave resonators which are described, or transversely coupled double mode surface wave resonators. Higher order filters can be provided by connecting further 2-pole filters in the cascade. The cascaded filter is particularly useful for filtering at radio and intermediate frequencies in cellular radio equipment.

Abstract: A latch assembly (1) of the kind having a latch bolt (3) which is mounted on a casing (S) for relative movement between an extended latching position and a retracted release position. The bolt is movable into the release position by operation of either one of two actuators (9, 12) which are accessible at inner and outer sides respectively of the latch assembly. The inner actuator includes a turn-knob or handle (9), and locking means (13, 14) associated with that actuator is operable to prevent operation of the inner actuator and thereby prevent retraction of the latch bolt (3) from the inner side of the assembly. The assembly includes lock release means (17) which responds to operation of the outer actuator (12) so as to deactivate the locking means (13, 14) and thereby release the inner actuator for normal operation. The locking means includes a spring loaded cam (22) which influences the position of at least one detent (18) and which is held in a locking means active position by retaining means (31) which is responsive to operation of the outer actuator. That response involves the retaining means releasing its influence on the cam member so that it can be driven under the influence of the associated spring (30) into a locking means inactive position.
