Title: Microprocessor controlled apparatus and method for forming metal building panels
Inventor: MORELLO FREDERICK
IPC: B21D11/20
Filed: 1994-04-29
Abstract: A microprocessor controlled apparatus and method for processing sheet material into building panels for assembly into buildings. The sheet material is formed into a panel having a flat bottom and sides while the length of the formed panel is monitored to control operation of the forming device. The panel is then fed into a curve-forming device which crimps at least a portion of the panel so that it is arched or curved. The curvature of the output panel is monitored to control the location of adjustable crimper rollers disposed in the curve-forming device to provide the portion of the panel with an accurate preselected curvature. The length of the curved portion of the panel is monitored when producing panels having both straight and curved portions, and the crimper rollers automatically reset to form portions with a different radius of curvature. Predetermined panel designs can be stored in a database and the microprocessor can control the apparatus to automatically produce such panel designs upon the input of appropriate data.

Abstract: A packaging case (C;C′) erected by folding from a one-piece vacuum-formed molded sheet, has rectangular walls (1-4;71-74) that fold, and are clipped closed, about an article (A;S) to be protected from shock. The ends of the case are almost-completely closed by conformal edge-to-edge abutment of end-flanges (8-11;78-81) of serpentine profile that are upstanding from the walls (1-4;71-74). The flange-edges are each molded with ridges (13, 15) and grooves (14, 16) that nest ridge-within-groove with those of the abutting edges, for absorbing shock. The walls (1-4;71-74) are hinged together edge-to-edge, and at their edges rise in steps (23,24,33.34,43,44) to a central plinth (22,32,42). The steps (23,24,33,34,43,44) of adjacent walls abut one another within the erected case for shock absorption, and each wall (1-4;71-74) is strengthened by circular recesses (25-28,35-38,45-49) of reducing diameter with depth, let into its plinth (22,32.42). The circular recesses produce frusto-conical shock-absorbing projections (57,58,60,62,63) on the outside of the case. The case (C′) may accommodate a stack (S) of component-carrying trays (T) protected by end-caps (83).

IPC: H04B7/005
Filed: 1985-05-01
Granted: 1989-06-28
Abstract: In communications apparatus, particularly cordless telephone sets, there is a need to maximise the number of communication links that can be made from a given area or volume. This is achieved by reducing the transmit power of a transceiver Y below its maximum in response to a signal level 50 of existing users V on that channel, as measured by the transceiver Y that is setting up a call. In particular, the reduction in transmit power p' is dependent on (e.g. equal to) the amount p by which the power of existing users exceeds a predetermined lower threshold TL. <IMAGE>

Title: Burner with air-supply regulator
Inventor: PAYSANT PAUL RENE PIERRE
IPC: F23D/
Filed: 1982-03-15
Granted: 1986-12-10
Abstract: The burner has an upstream air regulator which air must flow through before entering the air inlet of the burner. The regulator has a detector with an element subject to the pressure of the air supply to the burner as well as the air or gas flow downstream of the burner. A change in pressure in the combustion chamber causes a change in the equilibrium position of the element. A stepping motor is connected to the regulator whereby movement of the motor causes a change in the amount of air flowing through the regulator. The motor is actuated in response to a change in the equilibrium position of the element above a predetermined level so the pressure difference between the air supply to the burner and the air or gas flow downstream of the burner remain constant.
