Abstract: 1,023,619. Recording apparatus. HONEYWELL Inc. Nov. 2, 1964 [Nov. 4, 1963], No. 4467/64. Heading G1J. Recording-apparatus comprises (a) an endless belt 9 moving at uniform speed inside a housing 1 excluding ambient light except at a viewing aperture surrounded by a hood 6 with an inclined pane 7 of glass or transparent plastic and (b) a mirror 8 disposed so that a reflected image of a record being produced on the belt can be viewed. Records of a number of signals fed to an array of galvanometers 14 are produced by rays emitted by a mercury vapour lamp 12 and directed through lenses and by mirrors 13 to the mirrors of the galvanometers 14, which move in accordance with the signals to move the points of incidence of the beams on the belt 9 transversely to the direction of movement of the belt. The belt 9 is treated with a phosphor which responds to radiation from the lamp 12 to produce a luminescent record which fades completely in one revolution of the belt but lasts long enough to be viewed. A control panel 30, Fig. 3 (not shown), is at hand for an operator viewing the record so that he can obtain a permanent record at will either by (a) switching on (56) the drive to a continuous motion, streak-type, micro film camera 21 whereby part of the beam travelling towards the belt 9 is diverted to the camera lens 20 to produce simultaneously an identical record or by (b) pressing a button 39 to cause a timer 42 to stop the belt 9 for a predetermined time whilst opening the shutter of a Polaroid-Land type of camera 24 suitably mounted to photograph a direct or indirect view of the trace on the belt 9. Control handles 55, 60 are provided for presetting the speed and lens aperture of camera 21 and handles 41, 43 for the exposure time and aperture of camera 24. Time graduation marks can be recorded on the belt 9 and by the camera 21 by operating a handle 44 to make tubes 46, 47 flash under the control of a timing system 45 at preset intervals. Continuous longitudinal grid lines can also be recorded on the belt 9 and by the camera 21 by the emission of ultra-violet light from a tubular fluorescent lamp 23 passing through slits in an intensity control tube 67 which can be turned by a handle 64 more or less to obdurate slits in strips 68, 69 between the lamp 23 and the belt 9 and camera 21 respectively.

Abstract: 919,690. Power measurement. TAVOZLESI KUTOTO INTEZET. Dec. 19, 1961, No. 45478/61. Class 37. Microwave power from a waveguide is coupled to a rectangular hollow conductor 1 with matching stubs 2, 3 extending into a closed duct loop of rectangular cross-section immersed in a water-bath and closed from the atmosphere by an insulating foil 4 allowing passage of microwave energy, which is constrained by parallel fins 5 shown in section CD to pass through insulating plate 6 coated with a metal film, in which the microwave energy is transformed to heat and transferred to the contained air. The latter rises through parallel fins 7 (section AB) excluding microwave energy and the current deflects paddles 8, 9 suspended from torsion head 12. Suspended mirror 11 co-operates with telescope 13 and scale 14 to produce an indication of air flow, and the air current returns to its starting point, through the duct loop, during which it is cooled so that the rate of circulation represents heat generation and thus microwave power dissipated is shown by the mirror and scale. D.C. may be introduced to the element 6 for calibration.
