Title: Improvements in optical instruments
IPC: G02B27/10
Filed: 1949-12-12
Abstract: 692,617. Optical apparatus. HERRMANN, F. Dec. 12, 1950 [Dec. 12, 1949], No. 31889/49. Classes 97 (i) and 97 (ii). An optical instrument such as a theodolite, level, gun sight, rangefinder, microscope, spectrometer, goniometer or other instrument in which more than one field of view is observed comprises an optical system projecting a first field on to an eye-piece or graticule in front thereof to form a first exit pupil, and at least one further optical system, lying outside but close to the rays of the first system and pro. jecting a second field to form a second exit pupil which lies close to the first exit pupil whereby the fields can be seen separately by merely moving the eye. Fig. 1 shows a theodolite comprising objective 18, eyepiece 11 and graticule 12. The theodolite is rotatable about a vertical axis 10 and about a horizontal axis 15, scales 19, 17 being provided to indicate the respective rotations. Images of two diametrically-opposite portions of the scale 19 are formed at the graticule 12 by prisms 9, 8 and lenses 14 while similar images of the scale 17 are formed by prisms 16 and lenses 13, the exit pupils of the lenses 13 and 14 being separated from each other and, if desired, adjacent that of the theodolite system so that the observer, after sighting through the system 18, 11 must move his eye slightly to observe the scale readings. Fig. 2 shows an instrument for measuring the power of a lens and comprising collimator 25, objective 23, eye-piece 21, rotatable graticule 34 and lens power scale 31 including a linear portion. An image of a portion of the scale 31 is formed at the graticule 34 by prism 32 and lenses 33 having an exit pupil 36 spaced from that of the observing system 35. The image of the scale 31 is read against a circular line on the graticule 34, concentric with its axis of rotation, and the linear portion of the scale image serves as a fiducial mark against which a circular scale on the graticule is read to indicate its angular position. A scale reading system, applied to a spherometer or similar instrument incorporating a measuring microscope consists of a main scale 43, Fig. 3, divided and figured, for example, in mms. and tenths, adjacent an auxiliary scale 46 divided in mms. and tenths but figured in hundredths and thousandths of mms., images of these scales, at a magnification of 12.5, being formed in the graticule 41 of an eye-piece 50 by a lens 44. The graticule bears a zero line 42 against which the image of the scale 43 is read. The scale 46, moved parallel to the scale 43 by a screw 49, bears a fiducial mark 47 an image of which, at a magnification of #, is formed adjacent the image of the scale 43. By adjusting the screw 49 the scale 46 permits accurate measurement of the image of the scale 43.

Title: Devices for filling bottles
IPC: B67C3/26
Filed: 1976-08-03
Abstract: 1515804 Filling bottles PONT-A-MOUSSON SA 3 Aug 1976 [6 Aug 1975] 32208/76 Heading B8T Bottles are gravity-filled by a device in which an air vent tube is moved by a system of rods. A bottle B is raised to seal against gasket 9. Further raising of the bottle moves centring cone 8 and telescopic sleeve 10 relative to filling tube 6. Pin 23 contacts the upper surface of ring 25 and is moved upwards, this movement being transmitted by rod 22, balls 20, rod 18 (all in rigid sheath 19) and ring 16 into downward movement of vent tube 11 which is integral with nozzle 12. Orifice 14 is thus opened, as is the opening 15 of vent tube 11, so that the pressures in the bottle and above the liquid A in vat 1 are equalized and liquid may flow by gravity from vat 1 through orifice 3, body 2, and filling tube 6 into the bottle. When the bottle is filled to the level of opening 15, air can no longer escape through tube 11, pressure rises in the bottle and the flow stops. An external cam rotates ring 25 by finger 26 so than finger 23 may drop into a slot in ring 25. Rod 22 thus moves down and rod 18 moves up, together with vent tube 11 and nozzle 12 which thus seals again inside filling tube 6. The bottle is lowered, followed by cone 8 and sleeve 10, releasing finger 23 which disengages from ring 25 to enable the ring to return to its original position due to spring 28.

Title: Improvements in or relating to radio navigational aiding systems
IPC: G01S1/02
Filed: 1945-11-30
Abstract: 617,681. Radio navigation. MADDOX, H. F. Nov. 30, 1945, No. 32390. [Class 40 (vii)] In a radio beacon system for indicating at a mobile receiver its bearing with respect to a transmitting station of known location, the transmitted signals are in the form of regularly repeated pairs of short pulses, at least one pulse of each pair being radiated upon a directional beam which sweeps in azimuth over the zone in which bearings are required and the time spacing between the two pulses of each pair being varied in accordance with the instantaneous bearing angle of the beam. As shown in the Figure, the first 5 Ás duration pulses of the repeated pairs are radiated omnidirectionally from the aerial 19 by the micro-wave transmitter 17 under the control of the 1000 c/s. oscillator 14, pulse shaper 15 and modulator 16 and the 2 Ás duration second pulses of the repeated pairs are radiated from the highly directional rotating aerial 20, the timing of the second pulses being controlled by applying the output from the oscillator 14 to the modulator 16 via a 2 Ás pulse shaper and a delay network 23 which is mechanically coupled to the rotating aerial so that the delay. varies linearly from 10 Ás to 510 Ás for a complete rotation. At the mobile receiver, Fig. 4 (not shown), the received pulses are displayed by intensity modulation or as radial deflections on the circular trace of a long-after-glow cathode-ray tube, the trace being produced by applying phase quadrature voltages from a 2000 c/s. oscillator to quadrature deflection coils. The oscillator is synchronized by the first pulses of the repeated pairs which are selected by applying the positive video pulses directly to the control grid of a coincidence valve and through a delay network to the suppressor grid of the same valve, the delay time of the network being slightly less than 5 Ás so that the coincidence valve will be only opened due to the overlap of the two applied potentials when the received pulses are of 5 Ás duration or more. In a modification, the delay network is replaced by a relaxation oscillator generating a 5 Ás pulse which is then differentiated and the trailing edge used as a control potential for the coincidence value. The circular trace is shifted angularly by rotating the deflector coils around the neck of the cathode-ray tube until the spot due to the first pulse is aligned with an index mark associated with the bearing scale and the timing of the second pulse in terms of the bearing angle is then read off directly from the position of the spot due to the second pulse, Fig. 6 (not shown). The system described may be modified by radiating both pulses of each pulse pair from the directional aerial which may be oscillated over a limited angle instead of rotating continuously, and the first pulse may be distinguished by making it a double pulse. A plurality of beacons may be employed either operating at different R.Fs. or at a common R.F. with different pulse widths and/or pulse recurrence frequencies.
