Title: Laser synchronising device
IPC: H01S3/125
Filed: 1969-09-11
Abstract: 1,274,736. Lasers. COMPAGNIE GENERALE D'ELECTRICITE. 11 Sept., 1969 [13 Sept., 1968], No. 44980/69. Heading H1C. [Also in Divisions G1 and G2] Operation of a Q-switched laser is synchronized with that of further apparatus, such as a camera, by directing a light beam from an auxiliary laser on to a rotating resonator reflector effecting the Q-switching, or onto a further reflector fast with the rotating reflector, the reflected light beam being directed towards a light detector which supplies an electric pulse to the further apparatus when the rotating reflector is in a particular angular position. As shown, the Q-switched laser comprises a rod 2 of ruby, neodymium-doped glass or yttrium aluminium garnet, which is disposed in an enclosure 4, between fixed and rotating resonator mirrors 10, 12 and is pumped by a helical flash tube 6. The auxiliary laser consists of a He-Ne gas laser 14, one output light beam of which is directed at the rotating mirror 12 by an optical system comprising converging lenses 26, 28, a slotted diaphragm 30 and mirrors 32, 34. When the rotating mirror is in a particular angular position, light reflected by the mirror is received by a photomultiplier 42 through an optical system consisting of mirrors 36, 38, a converging lens 40, a slotted diaphragm 44 and a filter 46; and an electric control pulse is transmitted through a pulse shaper 48 to a camera 24. The laser 14 also produces a second output beam which is directed by diverging and converging lenses 20, 22 and mirrors 16, 18 on to an end of laser rod 2, the beam being reflected into the optical path of the Q-switched laser and providing a low intensity continuous output beam through partially-transmitting resonator mirror 10 which is used for visual alignment purposes. The plane ends of laser rod 2 are arranged parallel but off-normal to minimize parasitic reflections. Micrometer adjustment of the photomultiplier position may be provided.

Patent GB-1064572-A (GB)
Title: Improvements in method of forming a graphite sheet
IPC: C01B31/04
Filed: 1963-11-27
Abstract: Graphite sheets are formed by providing a body with a plurality of generally parallel pyrolytic graphite layers, placing said body in contact with an "intercalation" material which penetrates between said layers and <PICT:1064572/C1/1> decreases the bond strengthen between said layers, and then separating said layers into graphite sheets.  The body may be formed of first graphite layers which are separated by second graphite layers formed under different conditions from those operative when said first layers were formed; in which case the "intercalation" material penetrates said second layers and decreases the bond strength between said first and second layers. The "intercalation" material is an element or compound in liquid or gaseous form, the one employed in the examples being concentrated H2SO4 containing a small amount of HNO3.  The graphite body may be formed on plates 25 in the apparatus shown in Fig. 1, by admitting a carbonaceous gas, e.g. CH4, through line 21, and maintaining the temperature of the plates and chamber 18 at e.g. 1600 DEG  to 2500 DEG  C. Carbon vapour is deposited on both sides of the plates.  A second graphite layer of different properties may be formed by, e.g., charging the conditions of pressure or temperature or the amount of carbonaceous atmosphere present.  Deposition under the different conditions is repeated until a body of the required thickness, e.g. 250 to 2500 m , is formed.  The body is then cooled prior to removal from the plates, immersion in the intercalation material and subsequent water-washing or heating and separation into sheets.  The body formed on plates 25 may be annealed prior to treatment with the intercalation temperature, e.g. by heating at 2800 DEG  to 3800 DEG C. in an inert gas atmosphere in apparatus similar to that of Fig. 1. Examples given describe the production of graphite sheets 25 m  thick from a non-annealed graphite body with layers of two different types and from an annealed body with layers formed under constant conditions.  In the latter case some of the sheets are pressed together to yield a composite sheet.

Title: Echo sounder
IPC: G01S7/527
Filed: 1968-10-11
Abstract: 1,204,939. Echo-sounding; pulse discriminating circuits. FRIED. KRUPP G.m.b.H. 11 Oct., 1968 [12 Oct., 1967], No. 48342/68. Headings H3T and H4D. In an echo-sounder, echo signals are selected on an amplitude and duration basis by a device including an amplitude discriminator with a cut-in threshold considerably higher than its cut-out threshold. In the system shown, acoustic pulses of duration T are emitted by directional transducer 1. Echo pulses from transducer 3 are applied to selector circuit 5 via receiver amplifier 4 whose gain is controlled to compensate for increased attenuation with travel time of the acoustic pulses. The rectified amplifier output e contains portion ta (which is of no interest) and portion tb comprising fish trawl echo E1, fish shoal echo E2 and sea-bed echo E3 superimposed on background noise eb. For a digital indication of sea-bed depth, echo E3 must be selected by circuit 5 for closing gate 13, which normally passes clock-pulses z from source 12 to a counter 11. Circuit 5 comprises a Schmitt trigger stage 9 with a cut-in threshold n and a cut-out threshold m, which selects echo portion #a, E2 and E3 by amplitude discrimination. Since the sea-bed is an extended reflector its echo E3 can be distinguished from E2 by its greater duration. To this end the Schmitt output Ca, C2, C3 is applied to integrating network 10 to give output fa, f2, f3 from which f2 can be eliminated by a further Schmitt circuit 8 with a threshold level p. The leading edge of pulse g3 in Schmitt circuit 8 output is selected by logic circuits 17, 18 and triggers bi-stable 14 for closing gate 13. Diode AND gate 20 receives a first signal which is the inverse of Schmitt circuit 9 output, and a second signal which is present on line 15<SP>1</SP> during echo portion tb. Coincidence of the two signals makes transistor 21 conduct, thus shunting resistor 22 across a branch of the integrating network 10, whereby the discharge time-constant of the network is made shorter than the charge time-constant and the network output pulses are sharpened. Selector circuit 5 may be modified (no details given) to select some echo other than the sea-bed echo, for digital range indication on the counter 11 or on a second counter.

Abstract: 1277225 Electric motors; control of AC motors HITACHI Ltd 1 Oct 1969 [4 Oct 1968 23 June 1969] 48363/69 Headings H2A and H2J A commutatorless electric motor system comprises a rotary electrical machine M having a stationary polyphase winding and a rotating polyphase winding, and a switching arrangement SW for connecting the individual phase windings of one polyphase winding sequentially to. an external supply in dependence on the relative positions of the two polyphase windings as sensed from the voltages induced in. the switched winding by the other winding. As shown, the stator windings S1, S2, S3, are supplied from a thyristor inverter SW and the rotor windings R1, R2, R3 from a cycle-converter VF. A gate controller GC senses the voltages induced in the stator phase windings by the rotor winding and generates gate signals for the thyristors. Rotor speed may be varied by altering the inverter switching frequency on the rotor supply frequency. The rotor windings may be connected to the inverter instead of the stator windings. A motor system of the above type may be combined with a linear motor LM, as shown, to form a combined traction system. As shown, the linear motor primary windings L1, L2, L3 are connected to the same inverter SW as the rotary machine stator windings. Regenerative braking may be achieved by reversing the phase sequence of the rotor supply from the cycloconverter or by altering the frequency of the rotor supply such that the frequency of the supply for the linear motor windings falls below the synchronous frequency of the linear motor.
