Patent GB-1331790-A (GB)
Title: Percussive testing devices
IPC: G01N29/04
Filed: 1970-10-08
Abstract: 1331790 Percussive testing device SOC NATIONALE INDUSTRIELLE AEROSPATIALE 8 Oct 1970 [9 Oct 1969] 47824/70 Heading G1S [Also in Divisions H1 H2 and H3] A percussive testing device comprises a reciprocable striker 12 drawn against a fixed stop by a solenoid 8 and pushed away from the stop by a spring 15, the solenoid being in series with a switch 21 controlled by a pulse generator the solenoid and switch being shunted by a capacitor 25 fed by a direct current source through a current limiting resistor 24 so that when the switch is closed, discharge of the capacitor provides an attractive pulse in the solenoid and thereafter a circuit provides a smaller current for maintaining the solenoid in a condition to retain the striker and when the switch is again open the striker is released by the solenoid and is pushed by the spring. In use an operator listens as the device hammers a glued structure, the note produced informing the operator of the soundness or otherwise of the structure. The pulse generator 2 circuit which triggers thyristor 21 comprises a unijunction transistor 31, whose control electrode potential is determined by charge potential of capacitor 32 charged via variable resistor 19 and resistors 42 and 33. When unijunction transistor 31 conducts, potential is supplied via capacitor 28 and diode 35 to thyristor 21 and via diode 36 and capacitor 29 to commutating thyristor 22. When switch 20 is closed, capacitor 25 charges up, no current flows through solenoid 8 and a potential sufficient to block diode 36 appears at point 37 so that thyristor 22 is maintained 'off'. Diodes 40, 41 are trained backwards and do not conduct. When capacitor 32 is sufficiently charged, transistor 31 conducts and a pulse appears at 30 which cannot reach commutating thyristor 22 but causes thyristor 21 to fire, bringing point 47 to earth potential. This enables capacitor 25 to discharge through a solenoid winding 8 to produce the attractive pulse for drawing the core 10 and striker 12 into the solenoid against the force of the spring, the striker being held by a steady current flowing through resistance 24. With point 47 at earth potential, signals are prevented from reaching the trigger of thyristor 21 and the block to signals reaching the trigger of commutating thyristor 22 is removed, commutating capacitor 23 charges up (via resitor 45). Capacitor 32 charges up again but only through resistors 33, 19 and the new pulse from uni-junction transistor 31 goes to trigger commutating transistor 22 which fires and earths point 46. Commutating capacitor 23 discharges switching off thyristor 21 (thus cutting the circuit through the solenoid which releases the striker 12). The potential of point 47 increases to its original value and the whole circuit returns to its initial condition.

Title: Improvements in and relating to electric control circuits
IPC: H03K17/73
Filed: 1962-12-20
Abstract: 949,160. Control of D.C. motors. K. JONES. Dec. 20, 1962, No. 48247/62. Heading H2J. [Also in Division H3] A D.C. motor control circuit incorporating a silicon controlled rectifier, comprises means for applying to the SCR a charge flowing in the reverse direction to turn it off, the charge being derived from and dependent in value on the forward current flowing through the SCR. In Fig. 2 a load 1 such as a traction motor, is in series with a transformer and SCR1. A cross SCR1 is a capacitor C, a diode D and a transformer secondary winding TS1 in series, the winding TS1 charging capacitor C via diode D, in opposite sense and to a value dependent on the forward current. To turn-off SCR1 the pulse generator 2 is actuated by control unit 3 and this turns on SCR2 allowing capacitor C to discharge reversely through SCR1. The inductance of the transformer primary limits the current surge through the SCR on switching-on and the core saturates if the forward current is excessive so that the reverse current from charge the capacitor C does not exceed the safe value. Another secondary winding TS2 may cause the triggering repetition frequency to decrease if the forward current rating is exceeded. Automatic core flux resetting is provided by switch S1 and resistors R1, R2, switch S1 being closed before switch S2, allowing capacitor C to charge via resistors R1, R2. When switch S2 is closed, SCR1 is turned on and capacitor discharges through SCR1 via winding TS1 and diode D, thus resetting the core, before the load current builds up, and then is recharged in the opposite sense by winding TS1.

Title: Device for measuring the phase shift of radiation
IPC: G02F2/00
Filed: 1973-10-17
Abstract: 1437119 Measuring optical phase shift COMMISSARIAT A L'ENERGIE ATOMIQUE 17 Oct 1973 [23 Oct 1972] 48396/73 Heading G1A The phase shift produced by a system on an EM wave is measured by dividing the wave into two beams shifting the frequency of one of the beams by means of a rotating cylindrical diffraction grating, interacting one of the beams with the phase shifting system, recombining the beams and applying them to a non-linear detector which produces a beat signal the phase of which is measured to determine the phase shift of the system. As shown, Fig. 6, a laser 2 produces a wave 4 which is divided into two partial beams 8, 10. Beam 8 passes through the phase shifting system 16 while beam 10 is reflected from a rotating cylindrical diffraction grating 36 which produces a frequency shift by the Doppler effect. The phase shifted and frequency shifted beams are combined and applied to a non-linear detector 42 which produces a signal at the beat (difference) frequency the phase of which is related to the phase shift produced by system 16. Further beam splitters 108, 110 produce beams which are combined and applied to a second detector to produce a reference beat signal. The phase difference between the measuring and the reference beat signals is determined by circuits (70, 72, 74) which measure the respective zero crossing times of the two signals and subtract one from the other. A frequency or period measuring circuit receives one of the detector signals and produces an output which is combined with the zero crossing time difference to produce a measure of the phase difference which is equal to the phase shift introduced by the system 16. In a modification the components shown dotted in Fig. 6 are omitted. This arrangement can be used with systems 16 producing transient phase shifts the circuit being arranged to measure and store the zero crossing times when system 16 produces no phase shift. The zero crossing times of the signal when the system 16 produces the transient phase shift are then measured and compared with the stored values. The timing and processing circuitry may be digital. Alternatively the two detector outputs may be simultaneously displayed on a CRO and the phase shift estimated visually. The source may be a hydrocyamic acid HCN laser or a CO 2  laser, the IR radiation being detected by a pyroelectric detector e.g. of glycine sulphate or of TGS. A further embodiment producing two passes of one of the beams through the phase shifting system is also described Fig. 2 (not shown). The apparatus may be used for measuring the phase shift due to a plasma, the refractive index of a substance (which is related to the phase shift), the shape of a moving body e.g. a solid of revolution by reflecting the radiation from the surface and measuring the variations in phase as it is rotated, and displacements.

Abstract: 1,091,923. Cleaning pipes. MANN & RANKIN Ltd. March 15, 1965 [Dec. 13, 1963], No. 49395/63. Heading F2N. A drain flushing gun comprising a barrel 11 forming a pressure chamber which is charged with compressed air by a hand pump 18, a water inlet 35 having a non-return valve 37, a water outlet 36 adapted to be inserted in or placed in working relationship with the drain to be cleared, an air passage 33 extending from the chamber and connected between said inlet and outlet, and a normally closed discharge valve 34 in said passage, is characterized in that a discharge valve control member is provided which can be set to a " safety " position in which it is inoperative and to a " gun-firing " position in which it is operable to open the discharge valve. Said control member comprises a button 47 on the end of a crank-ended push-rod 45 which is arranged to abut a rocker arm 41 to open the valve 34 on depression of the button when the button, and hence the push-rod, is rotated to align marks, indicated at 49 and 50 in Fig. 2 (not shown), on the button and gun handle 16, respectively. This position corresponds to the " gun-firing " setting. Misalignment of said marks would allow the cranked-end 51 of the push-rod on depression of the button to move axially past the rocker arm without opening the valve thereby giving a " safety " setting. In operation, the barrel is charged by means of the hand pump. The water inlet is connected to a tap, the outlet directed into the drain, and water admitted to fill the pipes 33, 36 and any air space in the drain. The button is depressed when the button has been rotated to the " gun-firing " setting and the compressed air discharged. This air discharge sets up a shock-wave in the water which impacts on the obstruction to clear the drain. The provision of a " safety " setting ensures that the gun cannot be accidentally discharged when positioning it in the drain.
