Title: Built-up support member
Inventor: NATTERER JULIUS
IPC: E04B5/23
Filed: 1990-12-04
Granted: 1999-04-06
Abstract: A built-up support member for carrying bending loads is used in building construction. The support member is formed of two separate elements one superimposed on the other. The separate elements absorb normal forces caused by bending loads. One of the elements, for example formed of concrete, acts in compression, while the other acts in tension. Shear forces must be transmitted between the separate elements. Shear transmission surfaces afford a positively locked connection of the separate elements. The shear transmission surfaces include cooperating and complementary shaped projections and recesses. In addition, clamping elements can be provided between the separate elements in an un-prestressed or prestressed manner.

Patent CA-2038349-C (CA)
Inventor: DAVIS JAMES O
IPC: H01B7/08
Filed: 1991-03-15
Granted: 1996-07-09
Abstract: A multiconductor and support has a plurality of elongate  conductive  elements  each  with  a  pair  of termini.    An   elongate   support   means,   carrying adjacent conductive elements, has openings located at the distal and the proximal ends for alignment with conductive elements  extending thereover leaving the distal termini thereof  unsupported.   Heat  activated adhesive on the  support means bonds the conductive elements.  Each of the conductive elements are spaced from the  other  conductive elements and have center lines which are parallel.  A machine for assembly of a multiconductor and support means has a plurality of spools supplying conductive elements and a plurality of guides each positioned to receive and align the supplied conductive  elements.   The  guides  position the conductive elements spaced from and parallel to each other.  A supply of support means moves support means  intermittently but  synchronously between the conductive elements  and a flat  surface.   A heated platten compresses and bonds the conductive elements and the support means into an pair.   A method for assembling  a  multiconductor  and  support  includes intermittently moving several conductive elements in parallel spaced relation and intermittently moving a support means in a plane parallel to the conductive elements.   Pressing the parallel conductive elements and the support means together forms the pair.

Title: Liquid crystal display and manufacturing method thereof
Inventor: KAIDA YOSHIMASA
IPC: G02F1/1343
Filed: 1991-04-12
Granted: 1994-05-03
Abstract: Material obtained by reducing indium-tin-oxide is used as a shading material, for example, between picture elements of a liquid crystal display.   As  ITO is reduced,  its light transmission diminishes to a low enough level for the product to be used as a shading material.   ITO is widely utilized as a transparent electrode material in a liquid crystal display.  Because the region adjacent to the  transparent  electrodes  each  of  which  composes  a picture element electrode is generally where the shading is needed, the necessary shading member may be formed by reducing the region of ITO which is not protected with a mask, while protecting the ITO region which is to be used as  the  transparent  electrode.   Because  this  shading member is to exist in a single layer film of ITO,  no difference in level occurs between the shading member and the transparent electrode.  In addition, there is no need to separately form a film for forming the shading member, enabling the number of manufacturing steps to be reduced.

Title: Rotating-access atm-stm packet switch
Inventor: BESHAI MAGED E
IPC: H04L12/56
Filed: 1992-02-26
Granted: 1994-08-02
Abstract: A new architecture of an ATM or ATM/STM switching node which is functionally equivalent to the classical buffer-space-buffer  (BSB) architecture is disclosed.   In the basic embodiment, it uses middle packet buffers with a rotator (commutator) at its input and output.  It has two main advantages over the BSB architecture.  First of all, in the ATM mode, the need for arbitration when more than one inlet competes for the same outlet during the same time slot is eliminated.   Each packet knows when to proceed without being aware of the competing packets. This greatly simplifies the switching-control mechanism. Secondly,  the  switch hardware  complexity is reduced through the use of  clock-driven rather  than state-controlled cross points.  The cross-point ratio is 4/?n, where n is the number of inlets (outlets).

Title: Shoe insole for foot rehabilitation
Inventor: BURKE ROBERT GARFIELD
IPC: A61F5/14
Filed: 1992-06-02
Granted: 1997-02-11
Abstract: A shoe insole/midsole device configured to fit the profile of the human foot with a distinctive toe end and a distinctive heel.  The midfoot section of the insole/midsole device is characterized by an asymmetric domed structure that is presented to the plantar aspect of the foot at a location found to be the anatomical apex of the foot's arch system.  The asymmetric domed structure displays physical properties such as to catalyze muscle group balancing by utilizing the body's properioceptive feedback mechanisms.  The asymmetric domed structure displays physical properties such that it does not provide functional bracing or support to the plantar aspect of the foot.  The net result will be a more structurally sound foot capable of more energy efficient and less injury inducing use.  In addition to the predominant dome characteristic, the insole/midsole is also typified by a posterior most skiving which reduces impact velocity, thus easing the introduction of the dome characteristic to the plantar aspect.

Title: Method and allocating switching-oriented resources in a communication system operating in the asynchronous transfer mode
Inventor: HUNLICH KLAUS
IPC: H04L12/54
Filed: 1993-09-27
Granted: 2004-11-30
Abstract: The allocation of the switching-oriented resources of a communication system (KS) operating in the asynchronous transfer mode is controlled for connections wherein cells (Z) communicated by a communication terminal equipment (KE) connected to the communication system (KS) are to be switched without cell losses.      Logon information and scope of resources information (ai, ri) communicated within the framework of the call signaling are thereby entered in call-associated fashion into an immanent routing table (LT) of the communication system. Given reception of a first cell (Z) to be communicated free of losses, this and the further cells (Z) are switched with the assistance of the logged on switching-oriented resources (VR) in so far as no resources availability information (rvi) dependent on the traffic load of the communication system (KS) is entered into the routing table (LT).      Given a successful switching, resources use information (rvi) is inserted into the routing table (LT), as a result whereof the switching-oriented resources (VR) are exclusively allocated to the call for the switching of the cells (Z) to be communicated free of cell losses.
