Abstract: A method is provided for capping failure sequences in oligonucleotide synthesis by phosphitylation. A phosphite monoester is reacted with the 5′ or 3′ hydroxyl of the failure sequence between successive condensation steps in a synthesis procedure to form a 5′ or 3′ phosphite diester with the failure sequence. The phosphite diester substituent is inert with respect to subsequent reaction steps in the synthesis of the desired oligonucleotide product.

Abstract: A method of operating a display comprising a lattice of pixel elements (20), includes the step of time-multiplex addressing collections of pixel elements. This addressing step includes using a first shift register means (4, 26, 28) to designate operation of a second shift register means (6, 30, 32) to select a function to be performed. If the second shift register means (6, 30) is in bypass mode, then the first shift register means (4, 26) is effective as a mask to specify which of the stages in the second register means should be bypassed, and allows non-sequential group addressing of the pixel elements. Such an arrangement (2, 22) of first and second shift register means is suitable for use in controlling the addressing of collections or rows of pixel elements; the function to be selected by the second shift register means is the strobing of the collections or rows.

Abstract: A control processor in a robotic system treats optically sensed locations along the seam path ahead of the tool, which are classified in relation to elapsed distances and identified in 3-D coordinates and 3-axes tool orientation, to apply in real time and under feedforward a control signal representing the error between anticipated tool position and anticipated sensed location on the path. In the process, the anticipated sensed location is obtained by interpolation between actually sensed locations. A taught path is recovered from the robot. The control processor operation is also based on elapsed distances and related to actual tool position provided by the robot.

Abstract: A process for detecting a poorly coated portion of an inside surface of a pipe (5) coated with insulation coat (7) comprises the steps of providing a plurality of pigs (2) on a conductor (1) at predetermined intervals, preparing a running element (4) provided with many electrode needles (3) radially between these pigs (2), inserting the running element (4) into the pipe (5) while measuring the insulation resistance between the pipe (5) and the conductor (1), and moving the running element (4) inside the pipe (5) by adjusting the pressure inside the pipe (5). 
     From the above process, when the electrode needles (3) make contact with a poorly coated portion of the inside surface while the running element (4) is moving inside the pipe (5), the insulation resistance between the pipe (5) and the conductor (1) is decreased, thereby enabling the presence or a poorly coated portion and its position to be easily detected.

IPC: H01P1/19

Abstract: A fast switching ferrite phase shifter is disclosed featuring both reciprocal operation and fast switching speeds. Reciprocal operation in transmit and receive modes is achieved by employing two latching, toroidal non-reciprocal phase shifters (100,102); one for transmitting and one for receiving. The exemplary embodiment utilizes input and output circulating devices which include a Faraday rotator (108,110) and septum polarizer (104,106) for appropriately routing signals through one or the other of the phase shifters (100,102) depending upon the direction of input signal propogation. The phase shifter (100,102) achieves fast switching since the latching, toroidal, non-­reciprocal phase shifters (100,102) are transversely magnetized devices and are disposed entirely within a waveguide (101) so that the generated magnetic field is confined entirely within the waveguide. The phase shifters (100,102) do not intersect the waveguide walls and, thus, during a switching operation (eg, when the toroid magnetization state is changed due to release of the latching magnetizing current pulse), the magnetic field is not switched through conductive waveguide walls. Accordingly, eddy currents are not induced during a switching operation thereby allowing for fast phase changes to be accomplished (which are not limited due to eddy current delays). An embodiment is disclosed wherein forward and reverse propogating signals may be shifted in phase by individually controllable amounts which may be the same or different. Also, a device is disclosed wherein two waveguide ports are provided on one end (one to be connected to a transmitting means and the   other to a receiving means) so that in addition to the phase shifting function a duplexing function is performed.

Abstract: Motorised actuator for vehicle door locks e.g. as part of a central locking system has a powered drive input element (20), a drive output element (24) movement of which locks and unlocks the lock, and a clutch element (34) operating to transmit drive to the output element but having a disengaged condition permitting independent (e.g. manual) actuation of the lock. A camming formation (28) of the input element has a formation (34) of the clutch element coacting therewith and the clutch element has another camming formation (36) engaging another coacting formation (38) of the output element. The formation are provided with acting faces (32,44,46) angled so that drive force applied from the input element through the clutch element to move the output element against reaction loading of the latter acts to urge the clutch and output elements into positive drive transmitting engagement but reaction forces translated from the output element with no drive force from the input element releases the clutch engagement by camming the latter formations out of drive transmitting engagement automatically to put the mechanical into the disengaged condition. Preferably powered movement of the input element with the mechanism in the latter condition further shifts the clutch element into a superlocked condition in which the output element is positively retained in that condition.

Abstract: The invention relates to a process for administering additional respiration gas from a respiration gas source to a spontaneously ventilating patient, the respiration gas being administered to the patient during the inspiration phase of a respiratory cycle. In order, in this intermittent administration of respiration gas, to be able to administer the respiration gas to the patient in such a way that the latter does not in practice feel inconvenienced by the gas administration, the invention proposes that the course of the respiration gas volume administered to the patient per time unit should be adapted approximately to the course of the air volume inhaled by the patient per time unit, at least in a subdivision of the inspiration phase. The invention also relates to a device for administering respiration gas to a patient, comprising a respiration gas source, a respiration gas administration device, a respiration sensor (10) for inhalation or the like, a measurement arrangement and at least one valve in control communication with the respiration sensor (10) and the measurement arrangement. In particular for carrying out the process set out at the beginning, the valve (valves) is/are designed as metering valves (1, 19), which, together with the respiration sensor (10), is/are connected to a control arrangement (9, 17) regulating the administration of respiration gas during the inspiration phase of a respiratory cycle. <IMAGE>
