Title: Thermally insulated aluminum door frame
Inventor: TIZZONI SALVATORE
IPC: E06B3/263
Filed: 1989-12-01
Granted: 1994-12-13
Abstract: Abstract A frame  construction  for  a door  opening comprises an elongated aluminum extrusion which is adapted  to  be  secured  along  a  length  of  a  wall defining the door opening.    The aluminum extrusion includes  first  and  second  elongated  spaced  apart members each having an L-shaped profile and having first and second longitudinal free edges which form a channel  configuration  at  least  partly  open-ended towards  the  door  opening  between  the  first  free edges.   The first sidewalls of the first and second L-shaped members are parallel to the plane of the door  opening whereas  the  second  sidewalls  thereof extend towards each other at right angles from their respective  first  sidewalls  without  joining  one another.   An insulating vinyl strip extends between the first free edges in order to close the open end of the  channel configuration.      The  cavity  thus defined  is  filled  with  an  insulating  structural filler   material   generally   made   of   a   rigid polyurethane foam.    A thermal barrier is therefore provided in the frame construction as the first and second L-shaped members of the aluminum extrusion are separated  by  the  insulating  strip  and  by  the insulating filler material,   the latter ensuring a rigidity to the aluminum extrusion.   The method for producing this frame construction initially has the second  sidewalls of  both  L-shaped  parts  of  the channel integrally joining one another.    Once the cavity formed by the U-shaped channel closed by the insulating   strip has   been   injected  with   the structural filler material,   an elongated strip is removed  from  the  bottom  wall  of  the  aluminum U-shaped channel  with  the  integrity  of  the  frame construction  being  maintained  by  the  rigidified insulating structural filler material.

Abstract: ABSTRACT OF THE DISCLOSURE:         A particular signal sequence corresponding in a received signal to a symbol pattern consisting of a predetermined number of symbols at a symbol interval, is detected by sampling (45-48) into phase samples substantially at the symbol interval of a phase of a signal vector obtained by coherent detection (11) of the received signal, calculation (51-52) of phase differences, each between two consecutive phase differences. detection (56-5?) of consecutive instances of coincidence of each phase difference substantially with a predetermined phase difference, and determination (58-60) of presence of the signal sequence in the received signal when the instances of coincidence substantially reach in number to the predetermined number,  Preferably, the sampling is carried out by making (11) I and Q signals represent the phase and converting (46-48) the I and Q signals to the phase samples by using a clock generator (45).  When produced (46-47), I and Q digital signals represent their amplitudes, which are subjected to conversion (48) into the phase samples.  The conversion, calculation, detection, and determination can be processed by a digital signal processor.
