Abstract: ABSTRACT OF THE DISCLOSURE        A television signal transmission system comprises a headend including a pair of SAW filters having equal delays, one filter having amplitude and normalized phase versus frequency response characteristics continuously varying between about -6 db and 180 degrees at the picture carrier frequency and zero db and zero degrees at the sound carrier frequency of the television signal, the second filter having substantially flat amplitude and normalized phase responses between the picture and sound carrier frequencies.  An RF video signal is applied to both filters, the output of the first filter being selected for transmission during at least a portion of the horizontal blanking intervals of the television  signal with the output of the second filter otherwise being selected for transmission.  The transmitted signal is received by a decoder including a bi-phase stable phase modulation detector and third and fourth SAW filters having response characteristics complementary to the headend filters.          The received signal is applied to both the third and fourth SAW filters whose outputs are selectively switched to an output terminal in response to the phase modulation detector for restoring the received signal.

Filed: 1987-10-05
Granted: 1991-04-16
Abstract: Abstract A process for preparing 2-unsubstituted imid-azoles which comprises reacting an ?-hydroxycarbonyl compound with a formamide in such amounts as to make the molar ratio of said formamide to said hydroxycarbonyl compound not more than 2 at a reaction temperature of 100-170°C in an atmosphere of ammonia gas.  According to this process, 2-unsubstituted imidazoles may be obtained in very high yields.  In addition, because no great excess of formamide is used in carrying out the reaction, an effect of not requiring the recovery operation incident to decomposition of formamide is obtained as well.  And by removing formic acid formed as a by-product by the reac-tion, a reactor and separation equipment such as a dis-tillation column are not corroded, and imidazoles of a high purity can be obtained.

Title: Mechanism for loading and unloading containers onto and off a road vehicle
Inventor: LECLERC GILLES
IPC: B60P1/64
Filed: 1987-10-08
Granted: 1991-10-22
Abstract: ABSTRACT OF THE DISCLOSURE         A  road  vehicle  for loading  and  unloading containers has a tiltable frame on which a carriage runs, the carriage having a pair of clamps to engage the lower front corners of a container located at the rear of the vehicle.  To load a container, the vehicle is driven backwards to the  container  and the  frame tilted until its rear end rests on the ground in front of  the  container.    The  carriage  is  run  down the inclined frame by a winch-and-cable assembly and the clamps are secured to the container.  As the carriage is pulled back on the frame, it lifts the front end of the container; the vehicle,  with its transmission in neutral,  moves  rearwardly under  the  container being lifted without, however, being contacted by the frame.          At  one  stage  of  the  loading  operation,  a  pair  of longitudinal side elements on the frame are raised out of  their  gutters  to  contact  under  parts  of  the container to permit the container to be slid on the frame  while  maintaining  a  distance  between  the container and the frame. At the end of the pulling action, the frame is lowered to rest the container on two front support elements mounted to the chassis of the vehicle while the other two are mounted at the rear of the frame.  Then, the longitudinal side elements are lowered  in  their  respective  gutters  to  permit  the container to rest also on two rear support elements mounted at the rear of the tiltable frame.   Thus, at all times, a distance is maintained,  during loading, unloading  or  transport,  between  the  frame  and  the bottom of the container.
