Title: Infra-red image conversion apparatus
Inventor: GLANGEAUD YVES
IPC: H04N3/30
Filed: 1969-03-13
Abstract: 1,246,575. Television. SOC. EUROPEENNE DE MATARIELS SPECIAUX. 13 March, 1969 [14 March, 1968], No. 13235/69. Heading H4F. [Also in Division G2] In an infra-red television camera, operable at a high frame repetition rate, particularly for radiation in the 3-5 micron range, reflected or self-radiated rays from a point on an object are deflected and focused in turn by a mirror 10, a  lens system 11 and a mirror 12, to fall on a cooled point detector (4), 13, the mirror 10 being oscillated at constant angular velocity about an axis 23 intersecting normally with its optical axis, while the mirror 12 is disposed with its optical axis at a predetermined adjustable angle of several degrees to the main optical axis of the system and is rotated at constant speed about the main optical axis, so that a curtate cycloidal scan of the object is carried out, Fig. 3 (not shown). The system 11 may consist of a pair of plano-convex lenses as shown, or form, e.g. an Abbe system, and must have a central opening large enough to accept the detector (4) and cryostatic cooling holder 13. The mirror 10, which may be parabolic, or of the Fresnel or Mangin type, and is movable for focusing purposes, has a roller 21 engaging a motor-driven cardioid cam 20 for oscillation, while a pick-off device (41) on the same shaft as the cam 20,.e.g. a potentiometer, or a square wave pulse generator supplying pulses synchronous with the rotation to an integrator, gives signals indicative of the position of mirror 10. The mirror 12, of glass or metal and preferably toroidal, is rotated by a motor 27, and a device 28 generates two sinusoidal signals in quadrature indicative of the position of the mirror. At a receiver, the output of detector (4) is fed to the grid of a cathode-ray tube (C.R.T.), the appropriate one signal from generator 28 is combined with the signal from device (41) and fed with the other signal to respective deflection circuits for the C.R.T., Fig. 7 (not shown). The grid circuit may contain a differentiator and monostable multivibrator in series to give a silhouette of the scanned object while suppressing the actual image. To photograph the C.R.T. screen, a diohroic mirror is placed at an angle to the screen to reflect wavelengths from yellow to purple via a lens and a mirror to a camera while permitting direct viewing of the red, orange and yellow light from the screen, Fig. 8 (not shown). A shutter at the lens enables the exposure time to be arranged so that a series of exposures can be made. Combined with de-synchronization between the scanned image lines, sharp lines are softened and contrasts reduced. In modifications,more than, one detector (4) may be used, e.g. side-by-side, delivering signals to separate channels.

Title: Improvements in overload protection devices for d.c. electrical measuring instruments
Inventor: JABLONSKI JAN
IPC: G01R1/36
Filed: 1954-05-06
Abstract: 794,256. Automatic circuit-breakers. ELLIOTT BROS. (LONDON), Ltd. Aug. 8, 1955 [May 6, 1954], No. 13272/54. Class 38 (5). [Also in Group XXXVI] A protective device for a D.C. measuring instrument comprises a spring-loaded switch which is tripped to open the circuit of the instrument when the driving member of the instrument is displaced outside its given range of movement or when the driving member accelerates too quickly and moves relative to the indicator of the instrument. In the arrangement shown, should a signal of incorrect polarity or of correct polarity but of somewhat too great a magnitude be applied to the instrument, the moving coil 1 will strike the appropriate one of two abutments 19d on a lever 19 to turn the lever 19 about a pivot 3 and so move a pin 18 carried by the lever out of abutting engagement with the blade-like end 16a of a lever 16, 15. This lever is now turned by a spring 14 about a pivot 17 so as to move an end face 15a from abutting engagement with an edge 10b of a latch 10 pivoted at 11. The latch 10 is turned by the spring 14 until the edge 10b abuts a face 15b of the lever arm 15 and releases an arm 9 from a shoulder 10a enabling a spring (not shown) to turn the moving element 5 of the switch to open contacts 6, 7. Should a signal of correct polarity but of excessively high value be applied, then the coil 1 accelerates so rapidly that relative movement occurs between the coil and the pointer 22 against the bias of a light spring 32 which normally maintains the pointer in engagement with an abutment 29 on a plate 26 secured to the coil. This relative movement causes a lug 31 on the pointer to turn a wire element 30a about a lug 28 on the plate 26 so bringing the downturned end of the wire element into engagement with one of the teeth 19c formed on the lever 19. As the wire element is also being rotated about the axis 3, the lever 19 is turned to produce the tripping of the switch. Resetting is effected by turning the switch element 5 with a screwdriver slightly beyond its normal " on " position so that the lever 9 engages an arm 12 of the latch 10 and a finger 15c of the lever 15, 16 to reset the latch and the lever, the pin 18 being centralized by springs 20.
