Abstract: A table (10) is provided to assist in the manufacture of building structures such as walls and the like, where the walls comprise a plurality of studs (60) extend-ing between top and bottom members (14, 16). The table (10) comprises a support surface (12) for supporting the top and bottom members (14, 16) of the wall. In particular, the table (10) is most useful in manufacturing walls of steel studs. The Ata-able includes grasping means to grasp the building structure to be able to move the structure along the support surface (12) of the table (10). A computer operated con-troller controls motors to locate the top and bottom framing members as desired along the table and to locate the top and bottom framing members at desired loca-tions adjacent assembly stations (50, 52).  The assembly stations (50, 52) are used to attach a stud (60) to each of the top and bottom members (14, 16). The assembly stations are mounted on tracks and the location of the assembly stations along the track is controlled by a servo motor under control from the controller. The assembly stations may move transverse to the top and bottom framing members.  The assembly stations are also movable in a vertical plane so as to be movable below the support plane of the table and to be movable to a plane to form connections. The assembly stations are also pivotable about a vertical axis. By X direction movement of the top and bottom members, Y direction movement of the assembly stations, height adjustable movement of the assembly stations and pivoting of the assembly stations about a vertical axis, the assembly stations can be moved to attach studs facing in either direction or cripple studs to top and bottom members or headers to studs and cripple studs to headers or any combination. Preferably the assembly stations create button type joints by working metal of the top or bottom members and metal of the studs to form buttons. The assembly stations include punches and anvils which may be moved within a stud to form multiple buttons on each flange of a stud simultaneously with internal support for the two anvils.

Patent CA-2215999-A1 (CA)
Inventor: BOE HANS PETER
IPC: B32B17/06
Filed: 1997-02-13
Abstract: The invention concerns a semi-finished surface-cladding component comprising a pane of glass and a bonding mortar layer on one side of the latter, the bonding mortar layer consisting of a fine-particle neutral aggregate and cement and being prepared with an aqueous dispersion of a polyacrylic acid derivative. The polyacrylic acid derivative has a logarithmic decrement, determined according to DIN 53445, which is at a maximum at Celsius temperatures of less than 0°C. The bonding mortar is set on the pane of glass with a lack of hydration water. The bond with the surface to be clad can be produced as the result of contact between the bonding mortar layer of the semi-finished component and either the surface directly when it is the surface of a recently set, but not fully hardened, concrete, or, otherwise, by applying a so-called tile adhesive or concrete adhesive to the surface which the bonding mortar layer then contacts.
Patent CA-2216506-A1 (CA)
Inventor: KAZAKIS MICHAEL V
IPC: B60T17/00
Filed: 1997-09-26
Abstract: An  aftercooler  apparatus  condenses  vapor  in untreated  gas discharged from a compressor of a gas drying system.   The apparatus includes a radiator, a bypass line and a bypass valve.          The radiator features a first inlet,  a second inlet and an outlet.  The first inlet connects to the compressor from which it receives the untreated gas.  The outlet connects to the next component in the gas drying system.  The radiator condenses the vapor suspended in the untreated gas and passes aftercooled gas resulting therefrom via its outlet to the next component.  The bypass line, through which the untreated gas may flow, connects at one end between the compressor and the first inlet and at another end to the second inlet.  The bypass valve senses the difference in pressure between the first inlet and the outlet.          The bypass valve also controls the flow of the untreated gas in response to the difference in pressure.  When the difference in pressure is below a preset value,  the bypass valve closes thereby allowing the untreated gas to flow into the first inlet and through the radiator wherefrom the aftercooled gas passes to the  next  component while  carrying  therewith the  condensed moisture for expulsion from the system.  When the difference in pressure reaches or exceeds the preset value, the bypass valve opens thereby diverting the flow of the untreated gas through the bypass line and into the second inlet so as to defrost in the radiator frozen moisture accumulated therein that caused the difference in pressure.

Abstract: A golf distance indicator system provides measurement and display of the distance between a golfer and the pin on the green he is approaching. The system comprises a portable unit carried by the golfer and an target unit located on the pin.  With the portable unit, the golfer selects the hole he is playing then activates the system.  The portable unit sends a wireless coded message to an intended target unit.  When a target unit receives a message, it analyzes the message to see if it should respond.  If the target unit determines that it should respond, it sends a coded responding message to the portable unit.  When the portable unit receives a responding message, it analyzes the responding message to see if the responding message originates from the intended target unit.  If it does, the portable unit calculates a distance based on the elapsed time for the communications and the speed of the communications.  The results are displayed on the portable unit.

Inventor: LOUGHEED JAMES HUGH
IPC: F41G3/06
Filed: 1998-08-24
Abstract: A weapon which employs superelevation of the barrel, such as a grenade machine gun, comprises a barrel unit and an aiming system mounted upon a support. The aiming system comprises an imaging unit, a display unit for displaying an image of a scene within a field of view of the imaging unit, a rangefinder for measuring the range of a target in the f eld of view of the imaging unit, elevation angle measuring means for providing an elevation signal representing displacement of the imaging unit in elevation relative to the support, and a control computer for superimposing upon the image an aiming reticle and a rangefinder reticle, the former representing an aiming point of the imaging unit and the latter representing an aiming point of the rangefinder. The control computer adjusts the position of the aiming reticle in dependence upon the elevation signal, and stores coordinates for selected positions. The aiming system further comprises a coupling unit having a first part connected to the weapon for rotation in elevation with the barrel unit and a second part connected to the imaging unit. The coupling unit has a first state in which the coupling unit fixes the sight unit relative to the support while allowing elevation of the barrel unit relative thereto and a second state in which the coupling unit entrains the sight to move with the barrel unit relative to the support. A switch controls operation of the coupling unit to select the two states alternatively. The control computer computes a required change in elevation of the barrel unit in dependence upon a range measured by the rangefinder a.nd applies a corresponding offset to the displacement signal so as to displace the aiming reticle relative to the field of view in a direction opposite to the change. Where the offset is sufficient to displace the liming reticle beyond limits in the displayed scene, the control computer may be operable apply a part of the onset to position the aiming reticle adjacent a corresponding edge of the field of view and monitor the remaining offset, restoring movement of the aiming reticle with the weapon barrel unit once the barrel unit has been displaced by an elevation angle greater than said remaining offset. The control unit may change the appearance of the aiming reticle while the aiming point is outside the field of view.
