Title: Flexible support bar
Inventor: SANT PONT JOSE M
IPC: G12B9/08
Filed: 1992-04-21
Abstract: ABSTRACT                 FLEXIBLE SUPPORT BAR   . It comprises a core -1- formed by rigid sections -2- which alternate with flexible sections -3-,  supplied with flexible strips -4-, -4a-, -7-, -7a-,  which tend to recover their position when bent transversally along either of their larger faces.  The bar also incorporates a covering formed by a layer of plastic material -9-, two tapes -10- and -11-, which are wrapped firmly around it, and which produce friction between the strips and the op-posing faces of the core -1-,  The bar bends transversally at the regions occupied by the flexible sections -3-. The presence of rigid sections -2- gives greater resistance to the bar,  whilst the two tapes -10-, -11- provide the fric-tion between the strips -4-, -4a-, -7-, -7a- necessary to keep stable the bends produced in the bar.

IPC: B32B7/14
Filed: 1992-05-21
Abstract: Disclosed  is  a  dual  laminae  tissue  laminate  having  the laminae adhesively joined.  The laminae are joined by a water dispersible, and preferably water soluble, hot melt adhesive.  The adhesive is applied to one of the laminae in a longitudinally oriented stripe.   The  stripe  is  deposited  either in  a spiral pattern or,  preferably,  in a melt blown pattern.   This  stripe provides the advantage that softness is not compromised and that the tissue laminate may be easily disposed, without concern that the  adhesive,  or  the  laminate,   will  not  break  down  in  the presence of water.

Title: Tribo-attractive contact data storage system
Inventor: BREZOCZKY BLASIUS
IPC: G11B5/255
Filed: 1992-07-29
Abstract: A contact magnetic storage system in which the slider, which supports the magnetic read/write head, is in physical contact with a rigid magnetic storage medium during system operation  at  a  selected  operating  speed.   The slider material has a load versus friction characteristic that is non-linear in the negative load region.  This characteristic allows the slider to be suspended from an access arm with zero  or  negative  external  loading.   In  a  conventional magnetic storage system,  at operating speed the slider is lifted away from the surface of the storage medium by at least the thickness of the air film adjacent the moving storage medium surface.   In the present invention, due to the non-linear load versus friction characteristics of the slider material,  a restoring force is generated at system operating speed which overcomes the lift of the air bearing and maintains the slider in contact with the storage medium surface without substantial wear or damage to either the slider  or  the  storage  medium.   Various  single  crystal, polycrystalline and some amorphous materials have been shown to work in such a contact magnetic storage system.

Patent CA-2077255-A1 (CA)
Inventor: JUSTUS EDGAR J
IPC: G01L5/00
Filed: 1991-02-22
Abstract: A pressure sensitive device, such as a piezoelectric strip (16) or plurality of piezoelectric crystals (32), is or are arrayed along the surface of a roll, preferably in a spiral pattern, extending for one revolution of the roll (12) which is nipped with an-other roll (14). The nip pressure between the rolls, with or without a paper web passing through the nip, produces a signal by the piezoeletric device (16) indicative of irregularities along the nip (N). These irregularities, which can be indicative of variations in the web caliper, roll surface, hardness and other parameters of roll or web quality, are then passed to a monitor (38) for continu-ous read-out of the irregularities or non-uniformities along the face of the roll. Other apparatus, such as signal conditioning means (30) and encoder means (22), can be provided for processing the signals determining the exact axial location along the roll surface of the pressure sensitive device passing through the nip (N) at any given time.

Title: Process for recovering sorted plastic fractions
Inventor: KIRCHGAESSER PETER
IPC: B29B17/02
Filed: 1992-09-03
Abstract: ABSTRACT          A process for the computer-controlled recovery of sorted plastic fractions from a mixture of packaging materials is described.  Various screening, magnetic and ballistic separation steps are carried out.  Then the fragments remaining are transported through the remaining process stages individually and in strict sequence one after the other.  The sizes of the individual fragments of the isolated medium fraction are each identified by the computer control system by opto-electronic measurement.  The type of material of each individual fragment is identified during transportation by means of spectral analysis.          The results of this spectral analysis are input into the computer control system.  Depending on the results of spectral analysis, a removal system is triggered by the computer control system; this removal system moves each part into an appropriate collection system with other fragments of the same sort.

IPC: H01B17/12
Filed: 1993-03-26
Abstract: An isolating assembly for an overhead power line has a main sub-assembly formed of two parallel spaced insulators joined at their ends by aluminum end pieces. The end pieces each have a slot aligned with the space between the two insulators and a rod projecting from the end piece in alignment with the slot but below the slot. This arrangement enables the sub-assembly to be hung on a hot power line with the line passing along the slots and the space between the insulators. The rods may be clamped to the line by any suitable device such as wedges and C-shaped clamps. With the sub-assembly thus mechanically and electrically connected securely to the line, the line can be severed at a location between the end pieces and the free ends forced apart.

Patent CA-2099809-A1 (CA)
Inventor: WINTER AMOS G IV
IPC: E04C2/288
Filed: 1993-07-05
Abstract: ABSTRACT OF THE DISCLOSURE     An improved multi-layered panel, sometimes referred to as a stress skin panel, has a highly insulative multi-layered core located adjacent to one skin or alternatively located between two skins bonded to or otherwise rigidly affixed to the two outside surfaces of the core. The core of the multi-layered panal has a plurality of core layers which may be of the same or of different foam plastic materials. The layers of the core located adjacent to the panel skins provide a thermal barrier for the middle or second core layer which middle layer may be of a thermoplastic such as styrofoam and also may provide the means for bonding or securely affixing the panel skins to the surface of the multi-layered core. Borate, which is typically in the form of a powder (a borate compound used has been TlM-BOR? a product manufactured by U. S. Borax Corporation), may be incorporated, or encapsulated into selected layers or all of the layers of the panel core. Borates in the form of borate compounds similar to TlM-BOR? in an amount typically between about 2 weight percent and about 10 weight percent results in a core material which deters the entry of and the infestation of ants and other insects thereby enhancing an improving the usefulness of such prefabricated building panels. The addition of the borate compound has also been found to act as a fungicide and further, the flame retardant properties of the building panel are improved. Borate may be added, if possible, into the core material of any known prefabricated construction/building panel. However, it is most advantageous and effective if the borate is added during the fabrication of the core of the panel.

Patent CA-2105266-A1 (CA)
Inventor: FARWELL CHARLES Y
IPC: H04L7/04
Filed: 1993-08-31
Abstract: Signaling a mobile unit to transmit a synchronization pattern with voice information upon detecting from the signal strength of the wireless mobile unit by a base station that the mobile unit is approaching a minimum threshold. Where the voice information is initially being transmitted in a set of frequency hopping channels using spread spectrum transmission, the synchronization pattern is transmitted in one or more of the set of frequency hopping channels. In addition, the base station alerts a system controller to this fact, and the system controller requests that neighboring base stations monitor the set of frequency hopping channels being transmitted by the mobile unit. In order to synchronize to the mobile unit, the base stations utilize the synchronization pattern to come into synchronization with the mobile unit. The system controller transfers (handoff) the wireless mobile unit to the base station which is receiving the strongest signal strength.
