Title: Improvements in or relating to measurement of thickness
Inventor: AVEYARD SYDNEY
IPC: G01B17/02
Filed: 1962-02-12
Abstract: 993,149. Measuring by ultrasonics. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 7, 1963 [Feb. 12, 1962], No. 5390/62. Heading H4D. In an arrangement for measuring the thickness of an article 7 (Fig. 1) pulses of acoustic energy produced by a transducer 10 driven by a variable frequency ultrasonic oscillator 1 via a pulsing means 3 and reflected by the article are displayed on an oscilloscope 6 against a time base triggered by oscillator 4 controlling the pulsing means 3 and the required thickness is then deduced from the frequency of oscillator 1 at which destructive interference occurs between the pulses reflected from the front and rear surfaces 8, 9 respectively by utilizing the relationship that such frequency corresponds to a thickness of one half-wavelength or a multiple thereof. Fig. 2 shows the oscilloscope trace when the frequency is removed from such relationship the left hand pulse being the transmitted pulse and the right hand pulse the reflected pulse. When the frequency has the value required by the above relationship the latter pulse shows a pronounced dip (as shown by the right hand pulse in Fig. 3) indicating destructive interference between the pulses reflected by surfaces 8 and 9. The transducer 10 which is contained in a cork disc 11 provided with a hole 12 to provide a collinated beam, is coupled to article 7 by mounting both in water. The invention is intended for measuring the wall thickness of nuclear reactor fuel cans and for continuous measurement the oscillator is continuously swept in frequency such sweeping being employed to control a recorder (e.g. having a helical trace) which is also controlled by movement of the transducer relative to the fuel can and by a gate circuit which detects the passing of the reflected pulses through the minimum value and so causes a mark to be made at the frequency at which destructive interference occurs. When the fuel cans are made from two or more dissimilar materials bonded together the total thickness is measured if the bonding is good. If the bonding is not good only the thickness of the outer layer or layers will be measured so that the apparatus of the invention may be also employed to detect the presence of defective bonding.

Title: Improvements in or relating to monitors for use in television equipment
Inventor: NICHOLLS GILBERT
IPC: H04N5/445
Filed: 1957-02-18
Abstract: 845,440. Television. RANK CINTEL Ltd. Feb. 18, 1958 [Feb. 18, 1957], No. 5474/57. Class 40(3). Television monitoring apparatus comprises a single cathode-ray picture tube on which two pictures corresponding to two television signals derived from separate sources are displayed, effectively, simultaneously on non-overlapping areas. This is achieved by effecting the scanning in one of the two co-ordinate directions at one half the normal frequency and supplying the two sets of signals sequentially to the tube of half the frame frequency Fig. 1, shows the display produced (the two sets of signals corresponding, e.g. to a circle and a square), when the line scan frequency is reduced to one half and Fig. 2, that produced by reducing the frame scan frequency to one half. The altered aspect ratio of these two displays may be partly corrected by viewing them through a large cylindrical lens. To produce the normal 3:4 aspect ratio of the Fig. 1, display the amplitude of the line timebase is increased and that of the frame timebase reduced resulting in the display of Fig. 3, whilst reducing the amplitude of the line timebase and increasing that of the frame timebase allows the display of Fig. 2 to be altered to that shown in Fig. 4. A block circuit arrangement which allows either a single picture of maximum size and normal aspect ratio or any of the two displays described above to be produced is described with reference to Fig. 5 (not shown).

Title: Improvements in or relating to stoker systems
IPC: F23K3/14
Filed: 1951-03-07
Abstract: 685,415. Screw conveyers. STEEL PRODUCTS ENGINEERING CO. March 7, 1951. [March 16, 1950] No. 5511/51. Class 78 (i). In a stoker system in which a motor actuates a blower and a fuelfeeding screw, and a shear pin couples the driving motor and driven members, the pin is connected to a device which is vieldablv retained in normal position and positivelv moved therefrom to stop the motor and actuate a signal when the pin breaks. The shaft 40 of the screw conveyer is connected by a shear pin 45 to a sleeve 31 to which is connected a ratchet gear 32 driven by the motor. The part 35 of the sleeve 31 carries a sleeve 50 provided with a flange 51 and notches 52 to receive the ends of the pin 45. A flat 53 at one side of each end of the pin takes beneath the flange 51 and prevents the broken pin from falling out as soon as it fractures. The sleeve 50 is normally retained in the position shown by a compression spring 55 which bears against a collar 56 secured to the squared end 41 of the shaft 40. In this position also, the ends of a pin 62 fixed in the shaft 40 lie at the bottoms of inclines 61 formed on the inner face of the end 60 of the sleeve 50. When the pin 45 breaks, its ends are carried round by the sleeve 35, and since these ends engage the sleeve 50, this latter sleeve continues to rotate and also moves longitudinally by the action of the pin 62, which is now stationary, on the inclines 61. The longitudinal movement of the sleeve causes the flange 51 to swing the pivoted member 71 of a switch 70 to cut off the supply of current to the motor and to operate a visual and/or audible signal. The screw can be turned in case of necessity by a handle applied to the squared end 41 of the shaft.

Title: Devices for producing polarized light
IPC: G11C13/06
Filed: 1965-02-11
Abstract: 1,038,329. Lasers. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 11, 1965 [Feb. 28, 1964], No. 5905/65. Heading H3B. In order to produce a beam of polarized light from a laser a magnetic plate is inserted in the optical cavity to reflect light between one of the cavity reflectors and the active medium so that when the surface of the plate is magnetized the light is elliptically polarized when reflected due to magneto-optic effects. In the arrangement shown a magnetic plate 3 is inserted in the optical cavity 2, 6 of a ruby laser 1 so that when the plate 3 is magnetized in a direction parallel to the plane of incidence of the light from rod 1 and in the surface 4 then after a number of reflections the light becomes fully elliptically polarized in a direction depending on the direction of magnetization, Fig. 3 (not shown). In order to compensate for the effect of metallic reflections on the polarization of the light produced mirror 8 is inserted in the light path between plate 3 and mirror 6 arranged in a plane normal to the surface 4 and at an angle of 45 degrees to the plane of incidence of light acting on surface 4. The surface 4 may have different areas magnetized in different directions, Fig. 8 (not shown), so that the output beam has portions corresponding to the areas polarized in one direction or the other.

Filed: 1944-04-03
Abstract: 608,489. Automatic control of voltage;  control systems for synchronous condensers. BRITISH THOMSON-HOUSTON CO., Ltd. April 3, 1944, No. 6189. Convention date, April 5, 1943. [Classes 35 and 38 (iv)] In an automatic voltage stabilizing system for a line A utilizing a salient pole synchronous machine 1 excited in dependence upon the line volts so as to form a variable wattless load thereon, in order that the inductive loading by the machine may be increased, means are provided whereby its excitation may be reversed, excessive reverse excitation, such as would cause the machine to become unstable and slip a pole, being prevented by an automatic limiter. As shown, the shunt field 5 of exciter 4 is in series with a reversible booster 6, preferably of the armature reaction type, having opposed windings 12, 13 excited by the line volts respectively through a saturable choke 18 and a linear resistor 19. Under normal voltage conditions winding 12 provides a small excitation for machine 6 which slightly bucks the exciter voltage. When the line volts are low, winding 13 overcomes the effect of winding 12, the voltage of machine 6 falls and may reverse, causing machine 4 to provide increased excitation for the synchronous machine which then takes a leading current from the line and restores voltage to normal. Under conditions of high line volts, winding 12 increases the bucking action of machine 6 so that less excitation is applied to the synchronous machine which then takes a lagging current from the line. Further increase of line voltage causes the voltage of exciter 4 first to fall to zero and then to reverse, under which conditions machine 1 takes the heavy lagging current. To prevent excessive reverse excitation, machine 6 has a winding 20 fed from machine 4 through a normal non-conducting rectifier 21 biassed by resistor 23 in accordance with the line volts. When the bias is overcome, rectifier 21 conducts and winding reduces the output voltage of machine 6. The limiting action is increased by a non- linear resistor 22. In a modified arrangement, rectifier 21 conducts upon the reverse excitation current reaching a limiting value.
