Title: Socket assembly
IPC: F16L37/23
Filed: 1990-05-01
Abstract: Abstract A retainer ring holds parts of a socket assembly against relative movement.  The retainer ring is disposed in an outwardly facing groove in a first socket part and an inwardly facing groove in a second socket part.  A resilient seal ring is compressed between surfaces on the socket parts to press side surfaces of the grooves against surface areas on opposite sides of the retainer ring.  When the socket parts are to be assembled, the retainer ring is telescopically positioned on the end of the first socket part.  The second socket part is pressed against the retainer ring to move the retainer ring toward the outwardly facing groove along a flaring surface which expands the retainer ring.  The retainer ring is pushed into an outwardly facing groove in the first socket part by the second socket part.  When the retainer ring is in the groove in the first socket part, the retainer ring cooperates with the grooves in the two socket parts to hold them in their telescopic relationship.  As the retainer ring is pushed toward the groove in the first socket part, the seal ring is compressed between the two socket parts to apply preload forces against the retainer ring when the socket parts are interconnected.

Abstract: ABSTRACT           A human mammary cell growth inhibitor, and novel compositions comprising enhanced and purified concentrations thereof, inhibits the growth of human mammery cell. Inhibitor of the present invention purified by monoclonal antibody affinity chromatography comprises a thermolabile protein and has peaks of inhibitory activity at molecular weights of about 47,000 and about 63,000-67,000 as determined by SDS-PAGE. The inhibitory activity of the inhibitor is mammary cell specific, and is both calcium and dose-dependent. Increased production of the inhibitor can be induced by growth of inhibitior-escreting human mammary cells in low concentrations of calcium.  The inhibitor can be used prophylactically to decrease the risk of breast cancer, to screen for the risk or presence of breast cancer, and as a terepeutic agent for the treatment of breast cancer,

Title: Radio telemetry monitoring system
Inventor: SEALS DAVID G
IPC: G08B25/10
Filed: 1990-06-29
Abstract: RADIO TELEMETRY MONITORING SYSTEM          ABSTRACT   A system to monitor an electric  fence  or  a  secured area  uses  radio  telemetry  to  report  faults.   The  radio telemetry  transmitter  gathers  data  from a  fence  charge sensor, battery voltage sensor and/or switch contacts and encodes this information along with a unique address code in a serial data stream that modulates, by frequency shift keying  (FSK),  a  radio  frequency  (RF)  signal.   A  radio telemetry  receiver  intercepts  the  transmitted RF  signal and compares the received address code to a preprogrammed unique address code.   If code match occurs  the received data is transferred to the appropriate displays.  Various faults  are  reported  visually  and  audibly.   Fail-safe timers and error detector circuitry in the radio telemetry and transmitter receiver ensure the integrity of the radio telemetry link.

Title: Aggregate virtual channel
Inventor: MUSGRAVE PETER
IPC: H04L12/20
Filed: 1990-09-20
Abstract: ABSTRACT OF THE DISCLOSURE      A method is disclosed for transmitting signals having a bit-rate higher than a predetermined base bit-rate in a digital data transmission system normally providing discrete data channels having a predetermined base bit-rate, the channels being subject to different propagation delay characteristics through the system.  The method comprises allocating a group of C0...Cn-1 the predetermined bit-rate data channels as a virtual channel for the transmission of said high bit-rate signals, one of the channels Cm having a free bit position not required for transmitting data, dividing the high bit-rate signals into n sub-signals having a bit-rate equal to or less than the predetermined bit-rate, transmitting the n sub-signals over the n data channels, transmitting delay calibration signals at intervals over the data channels, the delay calibration signals being transmitted by inserting respective individual bits thereof on a rotational basis into said data channels.  Each bit of the delay calibration signals is inserted in the free bit position of channel Cm or in data bit positions of the other n-1 channels, the data bit that would normally be sent in a bit position occupied by a data calibration bit being sent in said free bit position of said channel Cm while its bit position is occupied by a data calibration bit.  The delay calibration signals at the far end to reassemble are used to reassemble the n subsignals into the original high bit-rate data signal.

Title: Mobile antenna system
Inventor: NISHIKAWA KUNITOSHI
IPC: H01Q1/32
Filed: 1990-12-10
Abstract: ABSTRACT OF THE DISCLOSURE         In  mobile  communications,  it is  required  that  the beam   direction is maintained to track the desired direction as  the  mobile  is  moving.  For  such  a  purpose,  the  mobile includes an angular rate sensor mounted therein which detects the  state  of  turn  in  the  mobile  and  to  control  the  beam direction of the antenna in accordance with the state of turn as well as the strength of radiowave received by a receiver in  the    mobile.  Antenna  elements  are  in  the  form  of microstrip   antenna and are  arranged  in plane  on  the  same dielectric   substrate.  Feeding and drive circuit layers  for controlling  the  transmission  and  reception  at  the  antenna elements  are    stacked  into  a  single  layered  unit.  This enables  the antenna system to be  formed  into a  low-profile structure.  The dielectric substrate of the microstrip antenna element  is  formed  by  stacking  a  plurality  of  dielectric substrate different  in dielectric constant from one another.          It  is  thus  intended  that  the band width of the antenna is increased  and  that  the mutual  coupling  between  the  antenna elements is reduced to prevent  the gain of the antenna from being lowered. Furthermore, the position of feed points in the antenna  element  are  rotated against  each  adjacent  antenna element.  This  can  improve  the  axial  ratio  in  the  array antenna over a wide band width.

Title: Technique for reducing the molecular weight and broadening the molecular weight distribution of high cis-1,4-polybutadiene
Inventor: CASTNER KENNETH F
IPC: C08F4/26
Filed: 1991-03-05
Abstract: Abstract of the Disclosure TECHNIQUE FOR REDUCING THE MOLECULAR WEIGHT AND BROADENING THE MOLECULAR WEIGHT DISTRIBUTION OF HIGH CIS-1,4-POLYBUTADIENE     High cis-1,4-polybutadiene can be synthesized by polymerizing 1,3-butadiene monomer with a three component nickel catalyst system containing (a) an organonickel compound, (b) an organoaluminum compound, and (c) a fluorine containing compound.  However, the molecular weight of the high cis-1,4-polybutadiene prepared is typically too high to be utilized as a non-oil extended rubber.  This invention is based upon the discovery that halogenated phenols act to reduce the molecular weight and to increase the molecular weight distribution of high cis-1,4-polybutadiene prepared with such nickel based catalyst systems.  The use of halogenated phenols as modifiers in such polymerizations does not change the microstructure of the high cis-1,4-polybutadiene produced.  Accordingly, the present invention specifically discloses a process for producing high cis-1,4-polybutadiene having a reduced molecular weight and broad molecular weight distribution which comprises polymerizing 1,3-butadiene in the presence of (a) an organonickel compound, (b) an organoaluminum compound, (c) a fluorine containing compound, and (d) a halogenated phenol.
