Title: Method of instrumenting an already erected concrete structure and the so instrumented structure
Inventor: BALLIVY GERARD
IPC: G01B7/16
Filed: 1990-04-23
Granted: 1993-12-21
Abstract: ABSTRACT OF THE DISCLOSURE              The present invention relates to a method of instrumenting an already erected concrete or rock structure  in  order  to  determine  the  state  of deformation  of  that  structure.     A  cylindrical inclusion made of concrete having substantially the same mechanical properties as the concrete or the rock of the structure is inserted into a hole drilled into the concrete or rock.   Sensors capable of detecting deformations  are embedded  in the concrete of the inclusion.  The empty space between the inclusion and the hole is tightly filled with a grout whereby any deformation of the concrete or rock structure also deforms the inclusion and is therefore detected by the sensors embedded therein.  The invention also extends to the inclusion and the so instrumented concrete or rock structure.

Patent CA-2046203-C (CA)
Title: Closure with high energy button
Inventor: HEILMAN ROBERT J
IPC: B65D41/16
Filed: 1991-07-04
Granted: 2002-05-28
Abstract: This related to a conventional type of closure having a control button which is normally provided with an "up" convex state and which is movable by a vacuum within an associated container to a "down" concave state. The button, as formed, has a zero or tensile stress state with the stress state changing to a compressive stress state when the button is drawn downwardly by a vacuum within the associated container. In accordance with this invention, the button has been reformed so that it is slightly flattened and this reforming has changed the zero or tensile stress state to a compressive stress state thereby providing the button with more stored energy when it is drawn downwardly by a vacuum within an associated container. This additional stored energy provides for a greater flipping action of the button which can be utilized to operate an irreversible tamper indicating system which may be applied to than button.

The plating resist material is preferably an insulator deposited by electrophoresis.  The plating resist material is removed, after plating the center portion with the other conductive material, to expose the gold plated contact regions.

Title: Low phase noise frequency multiplier
Inventor: CARFI RALPH WALTER
IPC: H03B19/18
Filed: 1991-08-08
Granted: 2000-10-24
Abstract: A low phase noise frequency multiplier is disclosed for multiplying a sine wave obtained from a low phase noise crystal oscillator to higher frequencies than can be directly obtained from a crystal oscillator. The multiplication occurs without the ordinary increase in phase noise. The multiplier, when tripling the frequency contains a low phase noise frequency doubler. The double and triple frequency terms in the tripler are synthesized from two orthogonally related derivatives of the same wave, which are then multiplied in a double balanced mixer.      The process reinforces the desired harmonics while not reinforcing the short term random phase noise, and produces a substantial improvement in the single sideband phase noise ratio over conventional frequency multipliers.

Inventor: REYES GREGORY R
IPC: A61K39/00
Filed: 1991-04-05
Granted: 2009-06-30
Abstract: Viral proteins derived from an enterically transmitted non-A/non-B viral hepatitis agent (HEV) are disclosed. In one em-bodiment, the protein is immunologically reactive with antibodies present in individuals infected with the viral hepatitis agent.  This protein is useful in a diagnostic method for detecting infection by the enterically transmitted agent. Specific epitopes have been identified that are reactive with sera of individual infected with different strains of HEV. Also disclosed are DNA probes derived from a cloned sequence of the viral agent. These probes are useful for identifying and sequencing the entire viral agent and for assaying the presence of the viral agent in an infected sample, by using probe-specific amplification of virus-derived DNA fragments.
Patent CA-2061967-C (CA)
Inventor: OETIKER HANS
IPC: B25B27/14
Filed: 1992-02-27
Granted: 2006-08-08
Abstract: A clamp structure which is provided with at least one pair of plastically deformable ear-like folds located on opposite sides of a center longitudinal cut in the clamping band and spaced in the circumferential direction by such a distance that they can be plastically deformed simultaneously by the use of a pincer-like tool. The pincer-like tool includes two sets of jaw-like members spaced from one another so as to permit simultaneous engagement of the two ear-like folds of a respective pair. The pincer-like tool may thereby have a relatively fixed center member forming a relatively fixed jaw-like member and two pivotally supported jaw-like members operable to be actuated toward one another. In the alternative, the pincer-like tool may include two sets of jaw-like members pivotally connected with each other whose points of pivotal connection are coupled with each other as also corresponding jaw-like members to assure movement in unison. By simultaneously plastically deforming the two ear-like folds while maintaining their relative position in the circumferential direction, a clamp structure can be realized devoid of any gaps, discontinuities or steps that might otherwise be a source of leakage.

Title: Hot water storage system
Inventor: ELIA PAUL
IPC: F24D19/10
Filed: 1992-10-19
Granted: 1996-07-23
Abstract: A hot water system for connection to a water supply and a local hot water usage system, comprising a plurality of series-connected reserve tanks and demand tanks for receiving water from the water supply, heating the received water to a desired temperature within the reserve and demand tanks, and supplying the heated water to the local hot water usage system as it is demanded. A controlling device is provided for sequencing the operation of the reserve and demand tanks relative to peak power consumption hours and off-peak hours. Specifically, each of the tanks is provided with one or more thermostats which are selectively enabled or disabled by the controlling device at predetermined times. The one or more thermostats are, in turn, connected to one or more heating coils or maintenance coils. The reserve tanks and demand tanks may be operated under control of the controlling device in any of three modes, as follows: maintenance mode, enable mode, and disable mode. In maintenance mode, the water is maintained at a desired temperature either via enabling a thermostat which is connected to a low-power maintenance coil and disabling the heating coil thermostats, or via cycling power through the heating coil thermostats if no maintenance coil is provided. In enable mode, the heating coil thermostats are enabled so that the water temperature may be increased in a tank via activation of the heating coils under thermostat control, and if a maintenance coil is provided then the maintenance coil thermostat is disabled. In disable mode, the heating coil thermostats, and associated heating coils, are disabled to minimize power consumption. If the tank is provided with a maintenance coil, then the maintenance coil thermostat and associated maintenance coil are also disabled when the tank is operating in disable mode.

Title: Laser beam detector for grade elevation measurement
Inventor: TAYLOR MARK E
IPC: G01C15/00
Filed: 1992-10-29
Granted: 1998-01-20
Abstract: This laser beam detector system may comprise an array of photodetectors usable in conjunction with a laser employed to define an elevation or grade.   The detector array is utilized on an elongate device having a plurality of faces, with a plurality of detectors disposed in a consistently spaced arrangement on each of the faces.  The detectors of each face have a field of view different from the field of view of the detectors of the other faces, and each detector on each face of the array is disposed at the same height as a  corresponding detector  on  each  of  the  other  faces. Importantly, each group of detectors at the same height are electrically interconnected into a co-functioning group. Our novel arrangement is such that a laser beam incident on any detector of a co-functioning group is detected, with the position of the detector upon which the beam impinged being identified, and a readout indicative of that detector then provided.   Such readout is conveniently in the form of a plainly visible representative character.
