Title: A structural element for constructions
Inventor: TRINGALI MARIO
IPC: E04B1/19
Filed: 1982-04-10
Granted: 1986-12-04
Abstract: This invention relates to a tridimensional structural element which can be composed with similar elements or with other components to obtain constructions and particularly coverings having low weight and high resistance. In order to obtain the highest possible static resistance, the best working conditions in whatever possible application and the possibility, without the need of any sliding part, of absorbing thermal expansions, the structural element according to the invention comprises a first body having an essentially polygonal plane surface and an even number of sides, six or more than six, as well as a series of bodies each having an essentially triangular plane surface, which derive towards the outside from alternate sides of the first polygonal body and are on planes forming angles to one another and with respect to the polygonal body plane, in such a way that all the theoretical vertices of the bodies simultaneously touch the surface of a curved surface. The structural element, which results to be "geoconverted", can follow any dimensional condition, either modifying the angles between the plane bodies to vary the radius of the surface as touched by the element vertices, or modifying at will, from zero up to a statically acceptable value, the length of the free sides of the polygonal body.

Title: Whirlpool jets
Inventor: MATHIS CLEO DONALD
IPC: B25B13/54
Filed: 1982-10-12
Granted: 1988-03-31
Abstract: A whirlpool jet housing having a unitary combination orifice and directional flow (ODF) that can be readily coupled and decoupled from the jet housing. The combination orifice and directional flow includes means (AA) for drawing air into the directional flow (DF) immediately prior to discharge of the water and thereby discharge a mixture of air and water. The combination orifice and directional flow is adapted to permit the coupling to a water inlet (W) for the jet housing to be continuously varied between a fully on and fully off position to vary the volume of water discharged. Control means are further provided to permit the user to turn the air fully on or fully off at the jet housing while controlling the flow of water at the housing. The whirlpool jet housing includes improved means (SS) for mounting the housing to a water vessel and an improved installation tool for use therewith.

Title: Microwave switch
Inventor: GREED ROBERT BRIAN
IPC: H01P1/15
Filed: 1983-05-20
Granted: 1988-09-22
Abstract: Microwave switches incorporating fin line structures enable microwave energy to be passed to a load or reflected back to the source by controlling the conductances state of diodes (14,15) mounted across the fin line structure.  In order to improve the electrical performance of such switches, the width of the waveguide channel (6) in the vicinity of the fin line structure (7,8) is greatly reduced hence suppressing the waveguide mode of propagation so that the fin line structure receives all of the energy applied to the switch. Tapered blocks (30) are provided for this purpose. Higher order modes which are generated at the fin line structure are attenuated by lossy material (33,34) positioned in choke cavities mounted on either side of the fin line structure.

Abstract: The method uses a scanner to produce switching signals dependent on marks on the periphery of the motor's rotor. Each switch-on of the motor causes any one coil (1-n) of the motor to receive current from an evaluator (6). When the motor rotates during starting the first and subsequent switching pulses from the scanner control the evaluator. These pulses control the evaluator in such a way that the evaluator generates the subsequent switching steps in the sequence of the wanted direction of rotation from the instantaneous position and rotation direction.
