Title: Ultrasonic image-producing arrangement
IPC: A61B8/00
Filed: 1970-06-03
Abstract: 1315712 Ultrasonic inspection devices SIEMENS AG 3 June 1970 [4 June 1969] 26904/70 Heading H4D In an ultrasonic scanning and display system, e.g. for medical diagnostic use, a mechanical drive for an ultrasonic beam transmitting and receiving probe is operable selectively in either a first mode or a second mode for scanning respective mutually angled first and second planes containing the direction of propagation of the beam, and a display device is operable to give a synchronized image of echo signals on a display area. As shown, the probe includes an ultrasonic directional transmitter 22 mounted for rotation about and translation along the focal axis of a cylindrical parabolic reflector 3; the display device is an oscilloscope tube 18. Switches enable either fast or slow drives to be selected for the rotation and translation and provide different selectable deflection modes for tube 18. In the Fig. 3 mode for providing a depth, z, versus horizontal distance, x, display, a fast continuous rotational and slow translational (either continuous or stepped) probe drive are selected so that the ultrasonic beam scans a family of substantially parallel xz planes, the display horizontal and vertical deflections being synchronized respectively with the rotational drive and the transmission of ultrasonic pulses by transmitter 22. In the Fig. 4 mode a depth versus vertical distance, y, display is provided by selecting a fast continuous translational and slow (continuous or stepped) rotational probe drive so that the ultrasonic beam scans a family of yz planes, the display horizontal deflection in this case being synchronized with the translational drive. The echo signals intensity-modulate the display in both Fig. 3 and Fig. 4. In the Fig. 5 mode a cross-section at a selected depth z in an inspected object is scanned by selecting a fast rotational and slow translational drive, a C-scan display being provided by synchronizing both display deflections with the probe drive and by time-gating the echo signals.

Abstract: 318,631. British Celanese, Ltd., (Assignees of Whitehead, W., and Dreyfus, C.). Sept. 8, 1928, [Convention date]. Apparatus for making filaments.-The extrusian orifices used for the manufacture of artificial silk. horsehair, bristles, &c. instead of being circular cross-section, are of compact or squat-shape having indentations in the form of re-entrant angles, for example as shown in Figs. 1, 2, 5, and 6.

Abstract: 1,106,505. Simulation apparatus. URWICK, ORR & PARTNERS Ltd. 20 June, 1966, No. 27351/66. Heading G5G. Apparatus for simulating, e.g. a machine shop comprises a number of units each representing a machine and an operator and each including a secondary, member 42 one revolution of which represents a completed operation, a primary member 34 rotated by a motor 32 which, when in use, frictionally engages the periphery of the secondary member and a number of discs 72-77 mounted on a rotatable shaft 78 and having recesses therein representing interferences in the operation, e.g. machine breakdown, coffee breaks and non-availability of essential materials. A switch in a switch box (4) (Fig. 1, not shown), is actuated to feed current to a master clock (12) and the units, and each unit is " set up " by manually releasing the primary member from a pawl 36. The switch 92 is then closed, and a " setting-up " plug E having conductive areas represented by shading is inserted in socket 56. Upon pressing button 61, solenoid 49 is energized to withdraw plunger 47 from groove 46, and rectifying circuit 107 which has a variable voltage control 11 1a then supplies power to motor 32 thus commencing rotation of the secondary member. Relay 80 is also energized and thus drive shaft motor 79 is activated. The associated circuitry of the unit is then subjected to interferences by discs 73-76 having recesses into which plungers 67a-70a of associated microswitches 67-70 are urged thus breaking " normal " circuits of the unit, the condition of the unit being indicated by lamps 52-55. Remedial procedures can be carried out by selecting one of a number of plugs A-D of different lengths and by placing the selected plug in an appropriate socket 57-60. After one revolution of secondary member 42, the plunger 47 will drop under gravity into groove 46. The unit is then stopped. The apparatus may have any number of units, connected in parallel, and two units may be inter-connected in a master/slave relationship by use of plugs F inserted in sockets 65. In this case the master unit has a disc 77 indented at 130, and the slave unit has a disc 72 indented at 129. The plugs F are so interconnected that re-energization of motors 79 and 32 (slave), after de-energization of those motors by plunger 66b of microswitch engaging recess 129, is dependent upon engagement of plunger 71b of master unit with recess 130 and consequent short circuiting of conduits 119, 137.
