Filed: 1968-03-04
Abstract: 1,151,988. Nuclear magnetic resonance apparatus. G. LAUKIEN. March 4, 1968 [March 3, 1967], No.10427/68. Heading G1N. [Also in Division A2] In a method and apparatus for non-destructively testing and sorting seeds, e.g. into genetically dominant and recessive (Mendel) categories, the seeds are fed one by one, from a container C by a device 1, to a micro-balance 2, which determines the weight G of each seed, which then passes to a nuclear magnetic resonance device 3, which measures the weight F of a specific substance in the seed. Examples of specific substances are: atomic nuclei such as those of nitrogen, C<SP>13</SP>, F<SP>19</SP> and P<SP>31</SP>, protons and hydrocarbons. The data G and F are passed, e.g. as an analog or digital electric signal, to a calculating machine or computer 5, which computes the quotient S = F/G and then compares S, namely the specific content, with a critical desired value Sc. The result of this comparison is sent, e.g. electrically, to sorting mechanism 4, which is provided with a sorting flap F4, and is, preferably, electrically controlled. When S-Sc is zero or positive, the flap F4 deflects the seed concerned, e.g. a dominant seed, into a receptacle 6b. When S-Sc is negative the seed concerned, e.g. a recessive seed, is deflected into a receptacle 6a.

IPC: G01S1/02
Filed: 1951-05-11
Abstract: 718,099. Monitoring servo-systems. SPERRY GYROSCOPE CO, Ltd. May 9, 1952 [May 11, 1951], No. 11178/51. Class 40 (1). A device for testing centre-zero control apparatus that includes a transmission channel for transmitting a control signal to a transmission device comprises means for injecting into this channel an auxiliary test signal together with the control signal, and means for producing from the combination of control and test signals at the output of the transmission channel two effects, one due to the control signal and the other due to the test signal, the latter effect providing an indication of the operativeness of the signal transmission channel. Fig. 1 shows apparatus for controlling the elevator 26 of an aircraft in response to signals from a control potentiometer 4, which may be a pick-off mounted on a gyroscope so that it gives indications of pitch of the craft, feeding a mixing amplifier 8, the output of which controls an electro-mechanical transducer 9 arranged to rotate a shaft 10 which controls the elevator 26 through a coupling 11. A test signal from a generator 14 is applied to the input terminals of the amplifier 8 through a capacitor 15 and resistor 16. The signal generator 14 may be an oscillator or pulse gener-. ator the frequency of the oscillations or pulses generated being sufficiently high to have no effect on the transducer 9. The output of the amplifier 8 is also connected to terminals A, C across the fixed coils 20 of a frequency responsive relay 18 through a capacitor 25. The output of the test signal generator 14 is also connected, between the terminals B, C of the moving coil 19 of the relay. When the signals from the generator 14 and also from the amplifier 8 fail, the relay drops back and operates a warning device 24. In a modification, Fig. la, the terminals A, C are connected to the primary winding of a transformer 61 having a centretapped secondary winding. The outer ends of the secondary winding are connected through metal rectifiers 63, 64 to resistors 65, 66 and capacitors 67, 68. Between the centre tapping of the secondary winding and the centre point of the resistor-capacitor combinations 65, 67, and 66, 68 is connected the secondary winding of a transformer 62, the primary winding of which is connected between the terminals B, C. A relay 69 is connected across the capacitors 67. 68, its normally closed contacts being connected to the terminals D.C. When the test signal from the amplifier 8 is present between the terminals A, C, a voltage appears across the relay 69. If the amplifier 8 is functioning normally, the voltage across the relay is sufficient to open the contacts. In an alternative arrangement, Fig. 2 (not shown), the test signal is supplied together with the error signal to the indicator, and produces vibration of the pointer if the amplifier is functioning correctly. Specifications 657,914, [Group XXXVII], 690,982 and 718,171, [Group XXXV], are referred to.
