Abstract: An echogenic medical devices adapted to be inserted into a patient, comprises an elongated member (123, 901, 1003) including a material (127, 1002) having an acoustic impedance different from that of the surrounding medium. For enhancing an image produced in response to a sonic beam produced from imaging equipment, the medium includes biological tissue or fluids surrounding the member when inserted into a passageway of the patient. The elongated member (901) also provides an interface (903) including the outside surface of the member and a plurality of partially spherical indentations (905). Alternatively, generally spherical particles (1002) are attached to the surface of the member (1003) for producing the image in response to the sonic beam. Materials such as stainless steel, plastic, and glass are utilized in the manufacture of the medical device. The device may also include an echogenic body member including a composite material echogenically imageable in the patient. The composite material includes a matrix material with discrete sound reflective particles made from a material different from the matrix material and embedded therein. Several sound reflective particles are disclosed, one type of particle being a glass microsphere about 5 microns in diameter. The matrix material (125) may be a plastic, and may be formed or extruded into devices such as catheters or other medical devices. The composite material may include different quantities of sound reflective particles by percent volume. Furthermore, a radiopaque material may be included in the composite material so the medical device is both ultrasonically imageable and radiographically imageable.

Abstract: The present invention relates to a polyamide-based composition used for the manufacture of moulded components exhibiting high resistance to attack by light and/or weathering. The invention more particularly relates to compositions comprising a thermoplastic matrix based on semi-crystalline polyamide, a black pigment and optionally reinforcing fillers. This composition is characterized by the presence of thermally stabilizing additives, in combination with a black pigment comprising at least one black pigment of inorganic origin and with at least additives which decrease the effect of radiation on the degradation of the polymeric matrix. The compositions of the invention exhibit improved stability in their properties under the effect of light and/or weathering, for example similar to that of polyester.

Abstract: Controllable polarisation transformer comprising a passive mode converter (4), a controllable phase shifter (5) and a controllable Mach-Zehnder interferometer (7). The mode converter (4) converts the first signal component of one polarisation (TE or TM) of a light signal entering via an input (1) into a signal component of the other polarisation without affecting the second signal component of the other polarisation (TM or TE), the conversion taking place to another order of the guided mode. Phase control by means of the phase shifter (5) controls the intensity distribution of the light signal over the two branches (8, 9) of the interferometer (7). Optical wavelength control in the interferometer (7) controls the phase with which the signals through the branches come together in the output (2). Advantages: very good integration capability, preferably on semiconductor material, with a waveguide structure which can be achieved in a single etching step and without critical manufacturing parameters; can be used reciprocally, even as a polarisation modulator. <IMAGE>

IPC: C01B17/765
Filed: 1980-11-07
Abstract: SO2-containing, hot gases are catalytically converted in part in a first contacting stage. The water and the SO3 formed is removed from the reaction gas. The remaining gas is heated and then supplied to the second contacting stage. The water vapor content in the reaction gas delivered by a first contacting stage corresponds to an H2O/SO3 mole ratio below 1. The reaction gas delivered by the first contacting stage is precooled by an indirect heat exchange to such a temperature that the wall temperatures of the heat exchanger are above the dew point temperature of the reaction gas. The precooled reaction gas entering a condensing stage is contacted in a venturi with cocurrent sulfuric acid of 98.0 to 100% concentration and a temperature of at least 95 DEG  C. The exit temperature of the gas from the condensing stage is maintained at least at 120 DEG  C. The gas rises in a succeeding absorption stage through a packing layer, which is contacted with trickling sulfuric acid having a concentration of 98 to 100% and a temperature of 70 DEG  to 120 DEG C. The dry gas which leaves the absorption stage and has been freed from SO3 is maintained at a temperature which is as high as or slightly higher than the temperature of the acid as it initially contacts the packing in the absorption stage. The sulfuric acid concentration is controlled by a supply of water into the sulfuric acid in the condensing and/or absorption stage.

Abstract: PURPOSE:To prevent a data signal to be transmitted later from being sent out from a transmission side by transmitting the data signal after a no-signal state for fixed time when the data signal is transmitted from the transmission side to a reception side, and stopping the transmission of the reception signal on the reception side when this no-signal is detected. CONSTITUTION:During a call between a radiotelephony set 2 and a called party side connected from a host equipment 1 through a wire line 3, when data transmission is executed from the radiotelephony set 2 to the host equipment 1, the some no-signal state is made by timer function previously provided on a control circuit 27 of the radiotelephony set 2 and afterwards, a transmission sound switch 38 is turned OFF at first. Then, a holding tone requesting signal made by the control circuit 27 is FM modulated and sent out through a transmitter 22. The receiver 10 of the host equipment 1 demodulates the reception signal. At this time, a noise detecting circuit 41 detects a noise level in the no-signal state and when the noise is caused by a data system, a signal showing the state is applied to a control circuit 16 by a signal line not shown in a figure. The control circuit 16 turns OFF a reception sound switch 11 by this signal. Afterwards, the holding tone requesting signal as the data signal is sent from the radiotelephony set 2.
