Abstract: 1432715 Switching systems for electric motors EICKHOFF MASCHINENFABRIK U EISENGIESSEREI mbH Gebr 20 Sept 1974 [11 Oct 1973] 41006/74 Heading H2J A switching apparatus comprises a first relay 6 for operating a switch 3, 2 for connecting a motor 1 to a power source RST, first and second rotary switches, hereafter called cut-out and cut-in 8, and a switch 7 in series with the first relay 6, a second relay 13 for operating the switch 7, a circuit for bridging the cut-in 8 and the switch 7, and a locking device 12 for coupling the cut-in 8 and the second relay 13 and arranged so that when the cut-in is closed to position II and the second relay 13 has been energized, this relay is mechanically held in its energized position in which the switch 7 is open. The apparatus is preferably a part of a sharerloader coal-mining machine. In operation cut-in 8 is moved to position II and cut-out, which is coupled, also moves to its position II, and relays 6, 13 are both energized, relay 13 after a delay. Switches 2, 3 are closed and the motor is energized. After the delay, energization of relay 13 opens switch 7. Cut-in 8 and cut-out 9 move back to position I under a spring bias control, and relays 6, 13 remain energized via the bridging circuit since switch 3 is closed. If cut-out 9 is moved to position 9 or emergency switch 10 is pressed, the motor 1 is stopped. If the emergency switch 10 is pressed and the cutin 8 is jammed in position II, since in these circumstances the locking device 12 maintains, via relay 13, the switch 7 open, the motor 1 will not be restarted when the switch 10 remakes the circuit in line 5. In a modification, Fig. 2 (not shown), a transistor device is in series with the relay 6 is provided and is only turned on when current is present in the main circuit including the cut-in device.

Abstract: 1,160,694. Photographic materials. EASTMAN KODAK CO. Sept. 15, 1966 [Sept. 15, 1965], No. 41185/66. Heading G2C. A photographic material comprises a radiationsensitive silver halide emulsion layer and a vesicular layer of a thermoplastic material containing a compound which releases a gas; the vesicular layer being the support or the two layers being coated on a support. The vesicular layer may comprise a thermoplastic resin and a compound which decomposes to release a gas, e.g. N2 on exposure to ultraviolet light. The vesicular compound may be a diazonium or azido compound, and after reflex or direct imagewise exposure and, if necessary, development of the silver halide layer to produce a silver image, the vesicular layer may be uniformly exposed to u. v., and then heated e. g. to 50-100‹C. for 5-30 seconds to form a white opaque layer which provide a good background for the silver image. The sensitive layer may be a direct-positive or negative silver halide emulsion layer. The vesicular layer is generally coated on the support and is overcoated with a subbing layer and then with the silver halide emulsion.

Title: Recording apparatus for echo sounding systems
Inventor: BREDE RAYMOND

Filed: 1968-08-30
Abstract: 1,209,097. Recording-apparatus. SIMONSEN & MUSTAD A.S. Aug.30, 1968 [Sept.4, 1967; Aug. 19, 1968], No.41579/68. Heading G1J. A recording-apparatus for echo sounding systems comprises a plurality of marking devices 3 arranged across the width of a strip 1 and switches 4 receiving output signals from an echo signal receiver and selectively from either a pulse generator 8 or 15 (the latter generating pulses of higher repetition frequency) so that the marking devices 3 are sequentially connected to the echo signal receiver at a frequency depending on the generator selected. The switches 4 comprise a plurality of twoinput AND gates whose outputs are connected respectively to the marking devices 3. Each has an input connected to an echo signal receiver 12 and another connected to a ring counter 6, 7 so that with a switch 16 in normal position, the devices 3 receive pulses sequentially from the generator 8, pre-set to a rate conforming with the depth range to be sounded. A suitable interval after the emission of a pulse by a transmitter 13, the ring counter operates and, when the echo is received, receiver 12 supplies a signal to the gates 4 (to cause a mark to be made) and also to an amplitude-sensitive discriminator 17 which controls the switch 16. When the signal exceeds a predetermined value, a sensitive element 17a triggers a multi-vibrator 17b and a gate 16b opens while a gate 16a closes, disconnecting generator 8 and connecting generator 15. At the higher frequency the marks are faint and to ensure that one device 3 will make a normal record of a signal exceeding the set value, an additional potential on a lead K derived from generator 8 is required to effect switching. The transfer back to generator 8 from 15 can take place after a predetermined time or by other means suggested. As an echo from the sea bed is the usual cause of the change to the higher frequency and more rapid scanning of the strip 1, time is saved over the part of the echo period which does not serve a useful purpose. Further time can be saved by terminating the sounding period when the switch 16 switches back to normal.
