Title: Modular construction system
Inventor: LOW GLENN
IPC: E04C2/00
Filed: 1987-10-27
Granted: 1991-10-15
Abstract: ABSTRACT OF THE DISCLOSURE               MODULAR CONSTRUCTION SYSTEM The modular construction system includes a plurality of lightweight, load-bearing composite panels to be used in the walls, ceilings and/or roofs of buildings, as well as for partitions within a given building.  Each panel includes sheet-like skins with a foamed plastic core therebetween.  At each end of the panel is a structural unit that is fabricated from sheet stock, the structural unit including a transverse sec-tion having a longitudinal groove formed therein.  When two panels are abutted in an end-to-end relationship, the grooves form a conduit for electrical wiring, com-munication lines and plumbing.  Each structural unit also has a thermal barrier so that the structural unit is resistant to the transmission of heat therethrough. The panels are connected in their end-to-end rela-tionship by means of interfitting lugs and slots on the structural units.  Additional structural units extend across the top and bottom of each panel.  The ends of the structural units are interconnected through the agency of additional lugs and slots to form a frame to which the skins are adhered and between which the formed plastic core material is introduced.

Filed: 1988-11-18
Granted: 1995-07-11
Abstract: Coded text is converted to phonetic data to drive a synthesis filter.  Accent data are also obtained to derive a pitch contour for a variable pitch excitation source. Recognition of the beginning of a paragraph causes a pitch contour of higher pitch than the pitch at a later part of the paragraph.   The  initial  pitch  falls  following each subgroup  into  which  phrases  are  divided.   In  another aspect  of  the  invention,  accents  within  a  phrase  are assigned pitch values which are high for the first accent, less  high  for  the  last;  and  the  remainder  alternate between higher and lower lesser values.

Granted: 1992-09-15
Abstract: ABSTRACT The prop comprises a central screw (3) and a nut composed of two parts (6a, 6b) disposed in a head (5) turning on the end of the support tube (1).  Said two nut parts (6a, 6b) are movable between a position of coopera-tion with the screw (3) and a position in which it is separated from the screw (3), under the control of arms (12a, 12b).  A return spring (16) urges said nut parts (6a, 6b) towards their position of engagement with the screw.       The flanks of the thread of the nut parts (6a, 6b) are symmetrical, while the external thread of the screw (3) has asymmetrical flanks, the bottom flank having a slighter slope, thus making it possible for the screw (3) to be pulled by hand into the top position without the nut parts (6a, 6b) preventing this.  Safety hooks (9a, 9b) limit the axial movement of the head (5) relative to the tube (1).       The prop offers the following advantages: The large displacements of the screw (3) in both directions can be achieved without the nut having to be turned.  Fine adjustment is made with minimum rotation of the head (5).  Two safety devices prevent the head (5) from moving out of the tube (1) in the case of one (8, 9) of these devices, and, in the case of the other (16), prevent the screw (3) from moving out of the head (5) and the tube (1), when the prop is inclined with its head downwards.
