Patent WO-8504069-A1 (WO)
Inventor: DERBYSHIRE RODNEY L
IPC: C21D1/40
Filed: 1985-03-06
Abstract: Appareil et procédé pour un traitement thermique sélectif d'au moins une partie d'un article in situ par chauffage auto-regulé. Le chauffage auto-regulé est fourni par un radiateur (110) comportant au moins un premier matériau magnétique (202) disposé le long de la partie de l'article (100) devant subir le traitement thermique. Le premier matériau magnétique (202) présente une perméabilité magnétique qui se modifie brusquement à des températures situées à sa température d'auto-régulation (AR) ou proches de celle-ci. Les modifications de la perméabilité résulte en des modifications correspondantes de la profondeur de pénétration du premier matériau magnétique (202) et, par conséquent, du chauffage qui y est produit en réponse à un courant alternatif le traversant. En maintenant le courant alternatif constant en amplitude et en fréquence, le premier matériau magnétique (202) et la partie de l'article (100) sont régulés essentiellement à la même temperature (AR) du premier matériau magnétique. En choisissant le premier matériau magnétique (202) de telle sorte que sa température (AR) corresponde essentiellement à la température de recuit, de trempe, de durcissement, d'adoucissement, de stabilisation ou autres du métal, le traitement thermique est effectué à une température auto-régulée. Le radiateur auto-régulé peut-être incorporé à l'article ou appliqué à l'article (100) par la suite, permettant dans chaque cas un traitement thermique in situ. Un chauffage auto-regulé peut également être effectué grâce à n'importe laquelle des diverses structures multicouches afin d'obtenir les effets d'auto-régulation désirés.

Title: Interactive television and data transmission system
Inventor: MARTINEZ LOUIS
IPC: H04N7/173
Filed: 1987-05-13
Abstract: A spread spectrum system provides bidirectional digital communication on a vacant television (TV) channel for simultaneous use by more than 75,000 subscribers using time and frequency division multiplex signals locked to horizontal and vertical sync pulses of an adjacent channel Host TV station (10). The system, whose operation is analogous to a radar system, comprises: (1) the Host TV station (10) to send down-link sync and data pulses to subscribers during the horizontal blanking interval (HBI), (2) subscriber ''transponder'' (14, 15, 16, 25) which detect those signals and transmits up-link ''echo'' data pulses only during the HBI to eliminate interference to TV viewers, and (3) a central receiver (6) which also uses the host TV sync pulses to trigger range gates to detect the up-link data pulses. In a preferred embodiment the central receiver employs directional antennas (28) to determine direction to transponders (14) and to define angular sectors partioning the service area into pie-link ''cells'' which permit frequency re-use in non-contiguous sectors (like cellular radio).
Patent WO-8801414-A1 (WO)
Inventor: ZENO JOHN RICHARD
IPC: G06F17/11
Filed: 1987-07-16
Abstract: A bit map image is stored as a two-dimensional array without z axis, by setting z arbitrarily at unity. Since two display axes exist as inputs, and two new axes must be generated as outputs, four lumped polynomial are solved for all transform possibilities, accommodating yaw rotations. A plurality of identical polynomial computation engines each provide numerical outputs at high speed that are the contiguous solutions for polynomial expressions whose particular coefficients have initially been provided by a host processor. These coefficients are supplied as a string of "delta values" as derived from a table of differences along a diagonal beginning at the first desired solution. The contiguous solutions begin at some specified starting value and continue as the variable "V" is increased by a uniform, specified increment. This method of solution is well suited to conventional raster-scan television (such as NTSC, PAL and SECAM) wherein each axis is scanned in a uniform and incremental manner. By using these two incremental axes as inputs ("V" values) to at least two polynomial engines (operating in parallel), the system can produce in real time address pairs which can read the map memory in such a way that, when remapped or displayed at a uniform linear rate, virtually any image perspective may be achieved.

Patent WO-8911732-A1 (WO)
Inventor: TONG PAUL CHAK FOON
IPC: H01L29/78
Filed: 1988-05-24
Abstract: Des interconnexions de faible résistivité et une zone active N+/P+ siliciée sont formées par dépôt par vaporisation d'une couche de titane (33) sur la surface d'une tranche (13) qui possède la configuration d'interconnexion définie par une couche mince de polysilicium (29). Une mince couche d'oxyde (27) sous la configuration d'interconnexion du polysilicium (29) sert d'arrêt d'attaque dans l'étape de photo/attaque de l'interconnexion locale. Cette couche d'oxyde non protégée restant sur la zone active N+/P+ est éliminée par une attaque par voie humide avant l'étape de dépôt par vaporisation. Le titane est ensuite fritté ce qui convertit le titane en TiSi2 et TiN. Le titane et TiN n'ayant pas réagi sont éliminés et TiSi2 restant forme les jonctions N+/P+ siliciées et un niveau d'interconnexion de faible résistance. Les avantages de l'invention comprennent également un procédé de contact autoaligné, de faible résistance pour la formation de la ligne binaire, et l'élimination de la nécessité d'un espacement minimal entre les transistors d'accès imposée par le procédé classique de contact non autoaligné.

Title: Adjustable support for cutting apparatus
Inventor: TRENTADUE FREDERICK
IPC: B28D1/04
Filed: 1989-02-07
Abstract: A cutting tool (10) such as a tile saw is pivotally connected to a linear guide rod (28) with a four-bar linkage (98). The linkage allows the cutting tool (10) to be raised and lowered over a work table (18) to facilitate plunge cutting. One link (54) of the four-bar linkage (98) is mounted over the linear guide rod (28) in a fixed perpendicular relationship with the surface of the work table (18) to ensure that the blade (45) of the cutting tool (10) is maintained in a similar perpendicular orientation throughout plunge cutting. This is achieved by adjusting the links (54, 32, 64, 86) of the four-bar linkage (98) as a parallelogram linkage. A linear bearing (36) is fitted between the fixed perpendicular link (54) and the guide rod (28) to allow the cutting tool (10) and linkage (98) to freely slide along an accurate linear cutting path.

Title: Equalization of load in threaded connections
Inventor: GREEN WILLIAM P
IPC: F16B37/12
Filed: 1989-03-15
Abstract: A threaded connection in which the axial load between a screw (11) and nut (15) in a tightened condition of the connection is distributed more uniformly between different turns of the engaged threads than in a standard threaded connection by forming the thread (14) of the nut (15) to have a pitch which increases progressively (Pa, Pb, Pc) as the thread (14) advances helically in a predetermined axial condition, while the thread (13) of the screw (11) has a pitch (P) which is uniform along its length. The pitch of the nut thread (14) may increase at a rate predetermined to compensate for differences in the tensile force which is applied to the screw (11) and the compressive force applied to the nut (15) at different points along their length when the screw (11) and nut (15) are tightened together to a prestressed condition.

Title: Genetic marker for superior milk production in dairy cattle
Inventor: COWAN CHARLES M
IPC: C12Q1/6876
Filed: 1990-02-16
Abstract: An assay for a genetic marker associated with increased milk production is disclosed. Also disclosed are kits for use in connection with the assay and breeding methods that use the assay. The assay centers on finding a genetic marker (e.g. at 1.15 kb) in a bovine cell (e.g. in the DNA of the cell). The presence of the marker is confirmed by exposing a gene sequence from the cell to a restriction enzyme so as to yield gene fragments of varying lengths. One then separates at least some of the fragments from others (such as by using electrophoresis), and one then hybridizes a plurality of probes that contain a portion of bovine prolactin sequence to the separated fragments. The probe is radio-labelled. One then compares the results (e.g. AA, Aa, or aa) of the hybridization with the hybridization results for a gene sequence known to either have the marker (e.g. Aa) or not have the marker (e.g. aa). The assay appears to be of greatest utility in connection with the Carlin-M Ivanhoe Bell Holstein family.
