Title: Spread spectrum communications system without a receiver synchroniser
Inventor: PANTHER GYLES
IPC: H04K1/00
Filed: 1992-04-03
Abstract: ABSTRACT             A direct sequence spread spectrum communications method whereby: at the transmitter, a highly accurate channel carrier is angle modulated with an audio or data signal and the modulated carrier in turn binary phase modulated by mixing in a double balanced mixer with a binary pseudo-random sequence to generate a suppressed carrier double sideband signal with a spectrum width determined by the clock rate of the pseudo-random sequence.  The pseudo-random sequence, may be generated by a pre-stored sequence of data read from memory or from a maximal length shift register circuit or from a computational means.  The spread spectrum signal is amplified in a power amplifier means and coupled to an antenna means for transmission.

Title: Trans-dominant suppressor genes for oligomeric proteins
Inventor: MERCOLA MARK K
IPC: A01K67/027
Filed: 1991-05-16
Abstract: A method of making trans-dominant, suppressor genes encoding mutant subunits of two different categories of oligomeric proteins is disclosed. In one category, the protein is composed of subunits at least one of which is initially synthesized containing extraneous peptide material. This extraneous material is subsequently removed during normal processing by cleavage at a proteolytic cleavage site to generate the mature form of the subunit.  According to the invention, single stranded DNA encoding the initial form of the indicated subunit is cloned, and the base sequence of the DNA in the region encoding the proteolytic cleavage site is modified by site directed mutagenesis so that processing of the translation product of the gene to the mature form of the subunit is prevented. In the other category, the oligomeric protein is one in which the monomers are bonded together by at least two disulfide bonds, at least one of which is essential for the catalytic activity of the protein. In the method of the invention, single stranded DNA encoding one of the subunits is cloned, and the base sequence of the DNA in the region encoding a cysteine residue essential for catalytic activity is modified by site directed mutagenesis.

Title: Balise identificatrice hivernale amovible
Inventor: DESCHENES EMMANUEL
IPC: E01F9/619
Filed: 1993-01-14
Abstract: Il est reconnu que l'utilisation de balises identificatrices hivernales est nécessaire pour marquer les installations ou les ouvrages susceptibles de se retrouver enfouis sous la neige durant la saison hivernale, ces balises devant servir de guide aux conducteurs de déneigeuses lors des manoeuvres de déneigement. La méthode de balisage la plus communément employée consiste en l'installation de tiges de métal plantées dans sol à chaque automne et enlevées à chaque printemps. Il s'agit d'une méthode mal adaptée aux besoins et qui est couteuse et peu pratique. Pour palier à ces inconvénients, la présente invention propose une balise avec tige-repère flexible et amovible dont la partie supérieure est munie d'une bande de matériel autoréfléchissant et dont son réceptacle de sol est installé de façon permanente. Une fois le réceptacle de sol installé en permanence, l'installation annuelle de la tige-repère consiste simplement à la visser de quelques tours dans l'embouchure du réceptacle. Lors de son enlèvement printanier un bouchon sert à fermer l'embouchure du réceptacle de sol empèchant la saleté de s'y accumuler. La tige-repère peut être fabriquée de différentes longueurs selon les besoins. La présente invention possède aussi un indicateur de bout de tige sur-dimension-né sur lesquel sont encollées des bandes de visibilité installées en séquences de couleurs différentes.

Title: Apparatus and composition for propelling an object
Inventor: HAMILTON BRIAN K
IPC: C06B29/16
Filed: 1993-02-18
Abstract: ABSTRACT    A charge assembly apparatus for propelling an object such as a fastening element.   One embodiment generally includes a propellant charge and a separate sensitizer which  are  substantially  totally  encased  within   a substantially non-rigid carrier strip.   A plurality of these charge  assemblies may be sequentially positioned within the carrier strip such that the present invention may be used with a fastening element driving apparatus in high  production  applications.     When  used  in  this application, the sensitizer is mechanically impacted by, for instance, a firing pin.  The sensitizer is then driven into  engagement  with  the  propellant  charge  such that sufficient friction is created to ignite the propellant charge.  The gases produced by combustion of the propellant charge therefore generate sufficient forces to propel the fastening  element  from  the  fastening  element  driving apparatus in the desired manner.   wp-lw(JMM)/2429-12.PAT/NETJLJ November 25, 1991

Filed: 1993-05-20
Abstract: Redundant facility payload signals (12, 14) received by redundant interface modules (16, 18) are redundantly provided (28, 30; 32, 34) to redundant downstream modules (24, 26) in an equipment (10). A non-symmetrical facility protection algorithm is resident in the B interface module (18). Symmetrical equipment protection algorithms are independently resident and operative in each module of pairs of identical A and B modules at each stage of the data stream. Module or data failures result in switchover only of the disabled data path or module so that the ability to transport payload is maintained and other modules or data paths are unaffected. Facility switchover is effected by detecting a working line failure and transmitting commands to switch the protection line to the A path modules. Equipment switchover is effected by checking for a working or protection module failure independently in each path and independently communicating independent switchover decisions to the other side and downstream. The methodology and mechanism are disclosed in a SONET element embodiment, although the invention is applicable in other contexts.
