Cette pression agit de façon à agrandir la section de ce manchon (3) par déformation plastique de ladite feuille (31) et à appliquer le manchon (3) contre la face inférieure d'un premier manchon (2) réalisé en un matériau composite perméable sur toute son épaisseur et enduit avec une résine thermodurcissable. La section dudit premier manchon (2) s'agrandit sans que le matériau composite subisse une déformation élastique ou plastique. Les deux manchons (2,3) réunis continuent à agrandir leurs sections jusqu'à ce que la face extérieure du manchon (2) soit appliquée fermement contre la face intérieure d'une enveloppe (1) réalisée sous forme d'une feuille en un matériau synthétique étanche. La pression (p) continue à agir à une température contrôlable et applique l'ensemble : manchon (2,3) et enveloppe (1) contre la face intérieure de la conduite (C). Après durcissement de la résine, la pression (p) est enlevée. Le manchon (3) adhère par ses fibres (31) au manchon (2).

Title: High density storage of information on a compact disc
Inventor: NOBLE LOWELL A
IPC: G11B19/02
Filed: 1987-07-24
Granted: 1992-02-25
Abstract: Abstract of the Disclosure An optical storage system achieves high density, sufficiently high to permit both video and audio to be stored on a compact disc, or to store other data at very high density.  Pits are encoded on the disc storage medium with respect to timed electronic reference signals (not simultaneously optically encoded on the disc) which divide each revolution of the disc into a multiplicity of equal spaces or references.  The pits have leading edges on the leading side of a reference signal and trailing edges on a trailing side of the reference signal, so that each pit straddles a reference signal.  The length of the pit leading up to the reference signal represents one sample of information, while the length of the pit from the reference signal to the pit's trailing edge represents another sample of information.  In this manner high density is achieved at high accuracy and low noise, since one end of each bit of information is precisely located and readable without the lesser precision involved in determining the location d the leading and trailing edges of the pit in reading the information.  On the disc the reference signal frequency is generated during the vertical retrace interval(s), encoded by equally spaced pits, for correlation with the prevailing speed of revolution of the disc.  At each horizontal picture line (e.g., 525 per revolution) there is at least one reference pit.  When this is detected the amount of phase shift which may exist at that line is measured and corrected for.  Two samples of the video waveform are reproduced and measured for each pit.  Small compact video discs can be produced with inner diameters of 2" to 4", or video bandwidths of up to 10 MHz can be produced for high resolution pictures.

Filed: 1988-03-01
Granted: 1997-02-11
Abstract: A  radio control toy incorporating a module containing a compact  television camera, radio frequency transmitter and radio control  receiver is described.  The camera incorporates a lens system  designed to record point of view impressions from the toy and  a microphone to provide impressions of the audio environment for  transmission  by the radio frequency transmitter to a remote television  module.   The television module incorporates means to receive  the  video  and  audio transmissions from the camera and reproduce   them  via  a  television  system  and  audio  speaker associated  with  the television module. A control module allows an  operator, viewing the television screen and hearing the audio sounds  reproduced,  to operate a set of controls associated with a  control  module  and control signals derived from the position of  the  controls  are transmitted by a radio control transmitter in  the  television  module to the radio control receiver in the camera  module.    The  camera module may be used in a variety of mobile  toys  thus  providing  the  operator  with  a pleasurable simulation  of  the  point  of  view  associated with much larger environments or full scale vehicles.

Granted: 1993-07-13
Abstract: ABSTRACT OF THE DISCLOSURE      A process for the recovery of propane and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed.  The stream is divided into first and second streams.  The first stream is cooled to condense substantially all of it and is thereafter expanded to the pressure of the distillation column.  After expansion, the cooled first stream is directed in  heat exchange relation with a warmer distillation stream rising from fractionation stages of the distillation column.  The warmed first stream is then supplied to the column at a first mid-column feed position.  The second stream is expanded to the column pressure and is then supplied to the column at a second mid-column feed position. The distillation stream is cooled by the first stream sufficiently to partially condense it. The partially condensed distillation stream i  then separated to provide volatile residue gas and a reflux stream.  The reflux stream is supplied to the column at a top column feed position.  The temperatures of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of the C3 + components is recovered.  Alternatively, control means may be adapted so that the major portion of the C2 + components is recovered.
