Title: Reconstruction system and method for ultrasonic imaging
IPC: A61B8/15
Filed: 1975-04-25
Abstract: 1511023 Ultrasonic imaging of specimens VARIAN ASSOCIATES Inc 25 April 1975 [25 April 1974] 17254/75 Heading G1G An object is imaged by transmitting through it pulses of ultrasonic energy along a plurality of intersecting paths, determining for each path the propagation time or any modification of some characteristic of the energy by the structure of the object, and processing the time or modification data by computer to reconstruct the image. In the Fig. I embodiment for ultrasonic imaging of a cross-section through arm 14, each transducer 11 in a ring of n (only six shown) is pulsed in turn under the control of commutator 16. Following a pulse from one transducer, ultrasonic energy is received by the remaining n-1 transducers over paths 18 and received data is stored in memory bank 20. The data relate to a characteristic of the gated leading edges of the received pulses and are compared with the same characteristic of the transmitted pulse to deduce changes attributed to regions 40, 42 along the paths 18. The characteristic may be amplitude, delay time, or pulse rise time. By varying the ultrasonic frequency, the first derivative of the pulse attenuation of the velocity or of the rise time change with respect to frequency may be determined to discriminate regions 40, 42. Computer 22 is programmed to reconstruct from the data the spatial relationship between the regions and controls a CRT or hardcopy printer to give a cross-sectional display of arm 14. A series of cross-sectional planes may be examined, the planar images being assembled into a three-dimensional representation of arm 14.

Title: Projection viewing apparatus
IPC: G06K13/07
Filed: 1971-05-27
Abstract: 1356594 Optical projection apparatus EASTMAN KODAK CO 27 May 1971 [2 June 1970] 17630/71 Heading G2J A microfiche reader includes a picture gate 156 to which a microfiche card 36 can be supplied from either chamber 26 or 28 via chamber 40 and means for aligning a selected image thereon with the optical axis. As shown in Fig.3, microfiche cards are arranged in stacks in the chambers 26, 28 by means of pushers 46, 44 and central partition 48. At the entrance to the chambers 26, 28 rollers 60, 62 are driven constantly in one direction and reversible roller 58 drives idler rollers 64, 66. As shown in Fig.3, a card 36 has been withdrawn from chamber 26 whereby the rollers 58, 62 by virtue of their directions of rotation strip only one card at a time from the chamber. The card 36 may pass from the chamber 40 to the picture gate 156 if the rollers 150, 152 are rotated to so permit it or it may pass to the chamber 28 when the rollers 58, 60 nip it and card deflectors 52, 54 guide it. The card deflectors 52, 54 are pivoted into the take up chamber 28 from beneath the partition 48 and the rollers 64, 66 act as guides. Reversal of the roles of supply and take up chambers requires the movement of the deflectors 52, 54 and reversal of roller 58 so that it strips with roller 60 and nips with roller 62. As shown in Fig.10 the rollers 150, 152 are driven by motor 158 via pulley 164 which can be connected to the shaft L by clutch C3. Mounted on shaft T are cams 168, 172, 174, and shafts T, L are connected by clutch C4. The rollers 150, 152 may be rotated to permit a card to enter the picture gate 156. When its leading edge is sensed solenoid SOL-1 is de-energized and cam follower 182 withdrawn and clutch C4 activated to couple shafts T, L. The apparatus shown is for use with a microfiche card having two rows of four images so that when the cams 172, 174 open the switches M1, M5, motor 158 stops, clutch C3 is disengaged and SOL-1 energized so that follower 182 exactly aligns the microfiche by resting in the detent 1 of the cam 168. To project a selected image one of eight control buttons is pressed and the carriage 202 carrying the card is raised or lowered by means of eccentric 194 to align the correct row of four images. This movement is terminated by the closure of switches S11 or S12. The solenoid SOL-1 is again de-energized and the shafts T, L rotated until appropriate switch M1-8 is opened, the follower 182 again providing the final precise alignment.

Title: Process for producing cellular fused silica
IPC: C04B38/02
Filed: 1972-04-18
Abstract: 1392724 Cellular silica; boron oxynitride CARBORUNDUM CO 18 April 1972 [26 April 1971] 17944/72 Headings C1M and C1A A method of making a cellular fused silica body comprises forming a substantially homogeneous mixture of finely divided silica and 0À1-10% by weight, based on the total weight of the mixture, of finely divided boron oxynitride, heating said mixture to a temperature of at least the melting point of said silica whereby the silica melts and the boron oxynitride decomposes to produce gas which forms closed cells within the molten silica and produces a cellulated mass, and cooling the cellulated mass to form a rigid body. Preferably the finely divided silica has a maximum particle size of 200 microns or less and a mean particle size of 10 microns or less and the finely divided boron oxynitride has a maximum particle size of 300 microns or less and a mean particle size of 15 microns or less. The temperature to which the mixture is heated is within the range 10- 50‹ C. above the melting point of said silica, e.g. 1700‹ C. for silica that melts at 1680‹ C. The mixture may be foamed in a graphite mould the inner surfaces of which are covered with boron nitride. The mould is placed in a resistance heated carbon tube furnace and heated in a current of nitrogen. The atmosphere during the heating may also be air or an inert gas. The cellular fused silica body so prepared has a bimodal closed cell structure, i.e. the material contains cells of two distinctly different size ranges, substantially all of the cells being non-communicating. The silica may be quartz, tridymite, crystobalite, amorphous silica, fused silica powder or silicic acid. Boron oxynitride is prepared by heating boric acid in an ammonia atmosphere, increasing the temperature gradually or stepwise to a final temperature of 700-1300‹ C. and continuing the heating at the final temperature until the desired composition is obtained. Boric oxide may be substituted for the boric acid. Preferably the boric oxide or boric acid is mixed with a carrier such as tricalcium phosphate to avoid agglomeration of the boron compound, the bicalcium phosphate subsequently being leached out of the product, e.g. with dilute aqueous HCl. Example 1 describes the heat schedule required to form a boron oxynitride of formula BN 0À79 O 0À21 .
