Abstract: PLUG-IN CONNECTION TO PERMIT FIELD     ABSTRACT OF THE DISCLOSURE           A gas-filled high voltage transmission line is disclosed which is made of sections of bus connected together at their ends.  Each section has a central elon-gated high-voltage conductor surrounded by a grounded outer housing which is filled with sulfur hexafluoride gas under pressure.  The central conductors are connected to one another by a sliding bridging contact covered by a sliding corona shield.  The outer housings are connected together by welded covers which span a gap between the ends of adjacent housings or may be bolted together.  Any bus section can be connected in place or removed without disturbing an adjacent section by cutting the weld and moving the sliding housing cover out of position or other-wise opening the housing and then axially sliding the corona shield and bridging contact into one central con-ductor and out of engagement with the other of the central conductors so that the entire section end can be moved relative to the adjacent bus section.

Abstract: ABSTRACT          Apparatus for the external setting or securing of the parts of a fractured bone, comprising an elongate central body member comprised of two parts mutually displaceable parallel to the longitudinal axis of said member, whereby each part of the central body member supports a clamping device for the pins to be inserted into a part of the bone.  The two mutually displaceable parts are engaged by a pressing and tensioning device causing the mutual longitudinal displacement of the part.  When the pins are inserted in the bone parts to be pressed together, the pressing and tensioning device is actuated until the two bone sections abut against each other at the required pressure.  Then the securing devices fix the two parts of the central body member into their position.          Subsequently, the pressing and tensioning device is removed from the central body member since it is no longer required.          For reliable guidance the two parts of the central body member are telescopically inserted one within the other and universal joints are provided between the central body member and the clamping devices for compensation.  These universal joints after being mounted on the bone to be put in splints are adapted to be fixed by fixing devices, so that a completely stable position of the whole apparatus is provided.  The pins to be inserted into the bone parts for reliable anchorage, in view of the tractive forces occurring at least in the section of the pin insertable in the bone, are provided with an external thread.

Abstract: ABSTRACT OF THE DISCLOSURE   An automatic washing machine of the fresh-water, vertical-axis type has a dynamic system which includes a single perforate wash basket arranged to be driven continuously such that its central axis moves in an orbital path about another axis.  The basket is restrained from rotating about its central axis when it is moving about the other axis and each point of the basket moves in a circulate path having an effective diameter which is small in relation to the diameter of the basket and having substantially the same excursion as the orbital path of the central axis of the basket.  Water and soil removing agent are introduced into  the basket during orbital motion and that motion is effective to induce a continuous motion of the fabric article load for washing the load.  The machine tub and other working components are placed in the moving system and provide a stable base for the basket.  Following washing, preferably the basket's central axis is positioned in substantial alignment with the axis about which it was orbiting and is rotated about this axis to centri-fugally remove water from the fabric load.  The basket is contoured to enhance toroidal and annular movement of the fabric load.  The machin transmission has an input shaft driven by a reversible electric motor, and an output shaft connected to the basket, the transmission having drive elements for interconnecting the output shaft and the input shaft.          The drive elements including eccentric drive members operative to shift the axis of the output shaft laterally from the axis of the input shaft when the input shaft is rotated in one direction, thereby driving the output shaft in an orbital path about the axis of the input shaft, and operative to return the axis of the output shaft from its laterally offset relationship when the input shaft is rotated in the other direction, thereby causing the output shaft to rotate about the axis of the input shaft.  A one-way clutch and a disc brake assembly, including an off-center coupling, cooperate with the drive elements to restrain the basket from rotating about its own axis when in the orbit mode and to rotationally drive the basket when in the orbit mode and to rotationally drive the basket when in the water extraction mode.

Abstract: 42-239(CANADA)/P2.32 FIBER OPTICS COMMUNICATION SYSTEM          ABSTRACT         A fiber optics transceiver transmits and receives either  synchronous or  asynchronous data through  a fiber optics data communication cable.   The  transceiver  is connected to one end of the cable and communicates with an identical transceiver at the other end of the cable.   The transceiver  includes  a  transmitter  for  converting electrcial digital data from a data source connected to the transmitter  to  optical  flux  for  the  cable.    For asynchronous  data,  the  flux  comprises  a  train  of positive-going pulses when the data is at a logical ONE, and a train of negative-going pulses when the data is at a logical ZERO.   The train of pulses is interspaced  at a fixed time interval and is restarted at each transition of the data between the logical ONE and logical ZERO state. For  synchronous data,  the  flux  comprises  a train  of positive-going pulses when the data is at a logical ONE, and a train of negative-going pulses when the data is at a logical ZERO.   Each of the pulses in the train correspond to one transition of a clock waveform to which the data is synchronized.  The transceiver also includes a receiver for converting optical flux  from the cable to electrical digital data for data equipment connected to the receiver. For  flux generated  from  asynchronous data,  the  receiver reconstructs the data.  For flux generated from synchronous data, the receiver reconstructs both the data and the clock to which the data was synchronized.  The transceiver also includes provisions for  indicating the operationality of the  data  communications  system  formed  by  the  two transceivers and the cable.

Abstract: PHB.32.686               11 ABSTRACT:        A method of growing III-V alloy layers by a mole-cular beam epitaxy process.  Difficulties have been experienced when growing doped III-V alloy layers by conventional molecular beam epitaxy processes due to the introduction of electron or hole traps which imapir the electrical and optical properties of the alloy.  Such III-V alloy layers are used in making microwave and opto-electronic semiconductor devices such as field effect transistors and layer diodes.  In the present invention, an epitaxial layer of a doped III-V alloy is grown on a semiconductor substrate by placing the substrate in a vacuum  chamber, reducing the pressure in the vacuum chamber to below atmospheric pressure, maintaining the substrate at a temperature in the range from 300 to 500°C, and directing a plurality of molecular beams containing the constituent elements of the doped III-V alloy and a molecular beam of lead onto the heated substrate.  The magnitude of the lead flux is sufficient to form and main-tain a presence of from 5 to 20% of a monolayer of lead on the growth surface.

Abstract: THRUST BEARING MISALIGNMENT MONITOR     Abstract of the Disclosure An apparatus for continuously monitoring the alignment condition of a thrust bearing based on a pair of temperature differences is adapted to utilize either analog or digital means.  The monitor is particularly applicable for use in large turbines, particularly those coupled to generators for the production of electric power.  Bearing misalignment and other variables are determined from temperature measurements of the oil feed temperature and from two temperature measurements made on diametrically opposite portions of the bearing surface.  The apparatus of the present invention is made possible by observed predetermined relations between certain computed tempera-ture differences which relate bearing thrust and mis-alignment moment and which also relate minimum oil film thickness and actual misalignment slope.
