Title: Label/leaflet assemblies
Inventor: DENNY BARRY D
IPC: G09F3/03
Filed: 1992-12-21
Abstract: A label/leaflet assembly includes a support web with a release coating on which is placed an adhesive label with a leaflet secured on its front face. The leaflet has a front cover one end of which extends beyond the underlying panels of the leaflets.      This end of the leaflet has a first part which is permanently joined to the main body of the front cover and which is releasably and re-sealably adherent to the label, and a second part which is permanently secured by an adhesive to the label and is connected to the first part and/or the main body of the front cover along one or more tear lines. Until opened the leaflet is held firmly sealed by the second part. When opened the leaflet is re-sealable, but the torn tear lines show that the leaflet has been opened. The assembly is thus tamper-evident.

Filed: 1993-09-03
Abstract: ABSTRACT          In a normal mailbox, it is known for it to be placed by the door somewhere or in the front yard.  It is the same for when someone places the address on the house.  There is no specific place where the address or the mailbox are placed. In this invention the address and the mailbox are placed together.  The advantages of this invention is that the address will be seen from a distance.  Also there will be a more lesser risk of your mail being stolen.  This mailbox will be placed in a certain place where others will be able to notice right away.  This invention can also be used by stores or houses on busy streets.  It could be installed right beside the doors.  The address will be on the outer side and the main body can be installed into the building. For houses, it can be installed into the house or installed outside by the side walk.

Patent CA-2091508-A1 (CA)
Inventor: GOSSEL CHRISTIAN
IPC: C10G1/04
Filed: 1993-03-11
Abstract: A process that can break down mixtures of water, solids, non-volatile hydrocarbons and other accompanying substances into their primary constituents employs solvent extraction such that the water, which is to be recycled, does not contain any solids at all.  The process makes it possible to process and break down oil-bearing sludge that accumulates during the hot water process of tar sands extraction, and which is stored in settling ponds and constitutes a permanent danger to the environment.  The process lowers the proportion of solids in the recycled water to nearly zero, which permits sedimentation within a reasonably short period of time.  The process is environmentally friendly and achieves high yields in bitumen separation with low energy and operating costs.

Inventor: FATEHI MOHAMMAD T
IPC: H04B10/08
Filed: 1993-06-16
Abstract: A performance monitoring technique which allows faults within an optical communication system to be detected and located. More specifically, a technique employing a signal generator to controllably insert maintenance signals at the input and output of each module within an optical communication system, and a single monitor to receive the inserted maintenance signals at a fixed point within the system, and, in response, determine the location of faulty modules. The monitor analyzes the received inserted maintenance signals, and locates faults by pinpointing modules from which a maintenance signal inserted at the module output is received uncorrupted by the monitor, but which return a corrupted maintenance signal whenthe insertion is made at the module input. A particular embodiment of the invention enables the maintenance signals to be inserted via pre-existing control drivers within system modules. This allows optical losses with the system to be minimized by eliminating the need for introducing of additional optical couplers or attenuators into the system.

Patent CA-2101262-A1 (CA)
Inventor: LAMPROPOULOS FRED P
IPC: G01D9/00
Filed: 1992-03-04
Abstract: An electronically controlled syringe system for connection to a balloon catheter or other balloon-type member and for automatically monitoring, displaying and recording inflation data when the syringe system is used to inflate the balloon of the catheter or other balloon-type member. A syringe having a barrel and a syringe plunger is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger further into the barrel. Positive pressure applied to the balloon catheter or member is released by withdrawing the syringe plunger toward the rear of the barrel. A piezoresistive semiconductor transducer housed on the barrel of the syringe senses fluid pressure applied by the syringe. The electric signal output by the transducer is input to a controller where the signal is digitally processed so as to derive and record therefrom electronic data representing the magnitude of applied fluid pressure, and so as also to derive the length of time that fluid pressure is applied. The electronic data representing this information is automatically displayed and recorded. In one embodiment, the controller is also mounted onto the syringe barrel to provide a digitally controlled inflation syringe system that is completely self-contained, and disposable.

Title: Method for setting a hair twist
Inventor: MOORE MELANIE
IPC: A45D7/00
Filed: 1993-10-25
Abstract: ABSTRACT           A method of setting hair including the steps of pulling a full handful of the hair back at the nape of the neck, making a twist going up against the back of the head, making a plurality of twists against the head and moving them upward toward the top of the head and into a roll having an edge.  The top of the plurality of twists is then pinched so the roll will not loosen up and pusching the remaining hair under the roll.  A particular hair comb is then placed, at a 90 degree angle to the head into the edge of the roll.  Finally the top of the comb is turned down toward the head while the comb teeth are pushed into the roll.  This new method of setting hair allows a person or a hair stylist to set hair in a neat,  consistent and appealing fashion.   This simple to learn method is cost effective and only requires a hair comb.

Inventor: BAUGH JOHN L
IPC: E21B33/00
Filed: 1994-10-12
Abstract: A seal useful for high temperature and high-differential pressures, particularly in sour gas wells, is disclosed. The preferred embodiment of the seal is an elongated member having features akin to a chevron-type seal at at least one end, coupled with at least one interference seal. A pocket is created in between these two elements which can trap atmospheric pressure, thereby enhancing the ability of downhole well fluids to compress the seal against a mandrel for facilitating its installation in a liner bore. The additional structural rigidity provided by the variety of alternative designs presented overcomes the tendency of the chevron portion of the seal to fail to seat due to downhole fluid pressures, displacing the chevron portion out of shape prior to its insertion into a liner bore.
