Title: Improvements in or relating to a method and apparatus for ultrasonic inspection
IPC: G01N29/34
Filed: 1964-03-11
Abstract: 1,034,724. Ultrasonic inspection. AUTOMATION INDUSTRIES Inc. March 11, 1964 [Oct. 7, 1963], No. 10311/64. Heading H4B. In a method of ultrasonic pulse testing, which combines the high penetration of low-frequency signals with the high short range resolution of highfrequency signals, a pulse of mechanical energy having a wide bandwidth is introduced into a workpiece and resulting echo signals are split into a number of frequency components which are selectively and sequentially amplified to provide components for indicating the physical characteristics of the workpiece. In a first embodiment, Fig. 1, a rate generator 10 provides trigger pulses to cause a pulse generator 12 to generate pulses (a) having a steep leading edge and a variable exponential trailing edge. These pulses have a wide bandwidth and are fed to a transducer 18 to produce correspondingly shaped acoustic pulses which are induced into a workpiece 20 having faults 20a and 20b. Echo pulses are received back by transducer 18, or by a separate receiving transducer, and are fed, via a broadband receiver 22, having a flat response over the frequency range of the echo pulse, to two bandpass filter amplifiers 24 and 26, respectively passing echo signal components at 2À25 mc/s. and 10 mc/s. The 10 mc/s. component contains echoes from near the surface faults, such as 20a with good resolution, but is greatly attenuated for deeper parts of the workpiece. It is passed to a C.R.T. display means 32, having a sweep circuit 16 triggered by pulses from rate generator 10, via a detector and amplifier, to produce a response 32a corresponding to the fault 20a. The 2À5 m/s. component contains echoes from all depths of the workpiece, but those due to near the surface faults are shown with poor resolution. The amplification of filter amplifier 24 is therefore controlled by amplifier gains compensator 14 such that only echoes from faults deep down in the workpiece, such as 20b, appear at the output of the filter-amplifier. Such echoes are then passed to the C.R.T. display to produce responses such as 32b. In a second embodiment, Fig. 2 (not shown), the echo pulses may be fed to a plurality of bandpass receivers, each having a different frequency pass band such that they pass echo components having good resolution at depths of the workpiece decreasing with increase of frequency and each having its amplification varied by an amplifier gain compensator such that it only passes echo signals to the C.R.T. display having the maximum resolution obtainable with the specific component frequency. The control produced by the amplifier gain compensators may be in the form of an on-off gating pulse or complex curves to obtain optimum band-pass characteristics. An alarm may be provided to indicate the presence of flaws.

Title: Improvements in Radio-controlled Torpedoes, Motor-driven Boats or other Self-propelled Units.
Inventor: ERICSON ARTHUR ENOCH
IPC: F41G7/30
Filed: 1917-07-21
Abstract: 128,295. Ericson, A. E. July 21, 1917. Torpedoes, locomotive.-Wireless control of the steering-gear of torpedoes is effected by providing similar commutator switches at the sending and receiving stations, each having its contacts connected alternately to form two sets, over which arms carrying brushes rotate slowly, and synchronously. At the sending station, the sets of contacts are connected to the poles of a two-way control switch in a circuit controlling the supply circuit of one or more transmitting aerials. At the receiving-station, the sets of commutator contacts are connected respectively to relays controlling the apparatus to be operated, such as a steering-motor capable of forward and reverse rotation. Interference may be prevented by providing two transmitting aerials sending waves of different frequency, the receiving-aerial having two tuned branches controlling contacts in series in the local receiving-circuit. Fig. 1 shows the sending circuits, and Fig. 2 the receiving circuits. The supply circuit 29, 30 for the two transmitting- aerials 20, 23 is closed by energizing a relay 14 in a circuit comprising a battery 13, a rotary switch arm 6, and two parallel branches, one including the outer set 5 of the commutator contacts and the right-hand contact 11 of the two-way switch 9, the other including the inner set 4 of commutator contacts and the left-hand contact 10 of the two-way switch. At the receiving-station the aerial 35 is grounded through two independent inductances 36, 36' by which the aerial is tuned to the two frequencies of the transmitter. The coherer circuits 38, 38<1> include relays 41, 42 controlling contacts 41<1>, 42<1> in series in a circuit comprising also a battery 47, a rotating arm 6<1>, and two parallel branches, one including the outer set 5<1>, of commutator contacts and a relay 54, the other including the inner set 4<1> of commutator contacts and a relay 50. As the arms 6, 6' are rotated synchronously, the relay 50 or 54 will be energized according as the control switch 9 is moved to left or right. The relays 50, 54 control contacts in circuits which cause the motor 69 to rotate in one or the other direction, thus driving the screw shaft 65 and traversing thereon a non- rotating nut 64 having a sliding connexion to a rod 61. This rod is pivoted at 62 and has a toothed sector 60 operating the rudder gear. Movement of the rudder is limited by a tappet arm on the nut 64 striking switches 80, 82 in the circuits of the relays 50, 54, respectively. The aerial 35 on the torpedo consists of insulated wires connected to arms 92, the lower ends of which are in contact with short metal tubes 90. These tubes are supported and insulated within the hollow masts 89 through which pass wires 91 connected to the receiving apparatus. The arms 92 are loosely supported on the masts so that the aerial may swing clear if one of the masts is broken or shot away.

Abstract: 668,183. Cathode-ray tube circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. April 24, 1950 [April 22, 1949], No. 10691/49. Class 37. [Also in Group XL (b)] In a cathode-ray tube beam deflecting circuit in which the deflecting coils are supplied with deflecting current from the secondary winding of a transformer, the winding is divided into two similar windings and means are provided for applying raster shift direct-current to the latter windings in such a manner that the current divides equally into the windings in opposing relationship so as to produce zero resultant magnetizing field. In the arrangement shown the deflecting coils 2 are connected across the " outer " ends of the two-secondary windings 4, 5, and the " inner " ends are connected together through a resistance 6 equal to the resistance 7, 8, of the deflecting coils so that two parallel paths of equal resistance exist between the " outer " end of winding 4 and the " inner " end of winding 5. When " shift " current is fed to these points (from source 9 and ganged potentiometers 11, 12, which move in opposite directions) equal and opposite currents flow in windings 4, 5, and zero magnetizing field is set up in the transformer. A choke coil 14, having an inductance which is large compared with that of the deflecting coils and a condenser 13 connected as shown, prevent deflecting current from passing into the source 9. The deflecting current source 1 may be the line or frame scanning waveform generator of a television system.
