Abstract: 982,609. Devices for measuring the height of material on a conveyer. SIMONACCO Ltd. Jan. 29, 1964 [Dec. 1962], No. 48510/62. Heading G1M. In a device adapted to sense the mean height of solid material being moved along a conveyer 14, fingers 26, pivoted to a support, trail over the surface so that on reaching a variation in the surface they pivot causing an arm 88 to depress a tappet 80 to operate a ball valve 76 seated in a passage 72 of a spigot 70 situated in a valve block 66. Passage 72 is connected to a further passage 74 leading to a tube 54. A piston 52 is slidably mounted in the cylinder 48 and loaded upwardly by spring 62; passage 34 being connected to pressure chambers 22, 24 through throttles 36, 38. In operation, when fingers 26 are displaced levers 86 are pivoted opening ball valves 76 causing a pressure drop in members 34, 48, 52, which provides a signal in pipe 46 to actuate an indicating, controlling or recording device.

Title: Method of and apparatus for measuring the frequency of non-coherent wave beam
IPC: G01S7/28
Filed: 1976-11-22
Abstract: This method is used for determining a Doppler frequency. In this method, the number of zero crossings of the input signal (ES) is counted by means of a "bad-value counter", the counter (7) is reset to zero with each ("good") value deviating from the last mean value by less than the predetermined percentage whilst the "bad" measurement values cause the bad-value counter (7) to be incremented; at a particular count, the bad-value counter, bypassing the comparison logic (2), causes the memory (3) to be filled up directly so that the same last value is stored at each storage location and, using the normal arithmetic of the averaging circuit (4), the duration of the last period is calculated as "provisional mean value" which replaces the normally formed mean value during the next evaluating operation so that in the case of initialization with a "good" value, the normal evaluating procedure leads to a valid mean value whilst in the case of initialization with a "bad" value the self-monitoring with the bad-value counter leads to a new initialization process. <IMAGE>

Abstract: 1, 245, 317. Photo-electric apparatus. OSOBOE KONSTRUKTORSKOE BJURO MINISTERSTVA GEOLOGII SSSR. Oct. 7, 1969, No. 49273/ 69. Heading G1A. Photo-electric apparatus for microstructural analysis (e. g. in mineralogy, biology, metallurgy &c.) comprises a stage 6, carrying the specimen 9, which is moved by drive-shaft 8 across the field of view of a photo-electric microscope 4, 10, 5. Differences in the reflectance or transmittance of the different components or phases of the specimen produce a detector output made up of different respective voltage levels. The detector output is fed through a cathode or emitter follower (matching) circuit to a device 11 which operates on the voltage levels in such a way as to render a selected voltage level (which corresponds to a particular phase or component in the specimen) a maximum (or minimum) as compared with all other voltage levels whether or not these were originally higher or lower than the selected level. In this way, when the signal is fed to an amplitude discriminator, (either directly or via a modulator 13 which chops the signal into pulse form in accordance with the output of pulse generator 15 triggered or synchronized by device 7 running in synchronism with the drive of stage 6) only the selected voltage level is passed by the discriminator 12 to presentation unit 3 for utilization. The unit 3 comprises multi-channel arrangement for receiving inputs from a number of units such as 2, each selecting a different phase or component of the specimen, and it can display counts (in percentage form if required) of the pulses in the pulse trains produced from these units 2. The unit 3 may also have a direct link from device 14 so as to display directly the reflectance or transmittance of the particular part of the specimen being scanned at a particular instant in time. The sensitivity of the selection unit 2 formed by devices 11 and 12 may be varied by alteration of the discrimination voltage of 12, the gain of 11 or the attenuation by a device in the output of 11.

Filed: 1973-10-31
Abstract: 1419878 Aerials BALL BROS RESEARCH CORP 31 Oct 1973 [17 April 1973] 50687/73 Heading H4A  An aerial structure 10, Fig. 2, comprises a ground plane 16, a single layer arrangement 12 of conductors including at least one R.F. radiator and associated feedline, a layer 14 of ferriteloaded dielectric material between the ground plane and the conductor arrangement, and means for passing a direct current through at least part of the conductor arrangement. The ground plane 16 may be a conductive layer on one side of the substrate 14, or it may be constituted, for example, by the skin of an aircraft. The conductor arrangement 12 may be formed by a printed circuit process from a conductive layer on the other side of the substrate 14. As described, a vertical co-linear array of radiators N 1  to N 4 , Fig. 1, is provided and is fed from an R.F input 18 by means of a symmetrical branching network. A variable direct current source 26 is connected through a connector 36 to a part 28 of the R.F. feed line to the radiator N,,a connector 38, a part 30 of the common R.F. feed line to the radiators N@ and N 4 , a part 32 of the R.F. feed line to the radiator N 4 , and a through connector 40 to an earth 44. Isolation is provided by means of by-pass capacitors 34 in the R.F. feed lines and by suitably located opencircuited quarter wavelength stubs 42 in the D.C. connectors. The parts 28, 32 are equal in length, and the part 30 has twice that length. Thus, if a particular current from the source 26 produces a phase shift # in the feed line to the radiator N 2 , it produces phase shifts of 2# and 3# in the feed lines to the radiators N 3  and N 4 . By varying the current from the source 26 the beam from the array may be scanned in a vertical plane. Further control may be obtained by providing voltage dependent devices, e.g. Zener diodes functioning as varactors, at selected points in the feed network (Fig. 5, not shown). In another embodiment (Fig. 6, not shown) four arrays as shown in Fig. 1 are assembled side-by-side and are coupled to a common direct current source. Their respective R.F. inputs (18 in Fig. 1) are fed from a common R.F. source by means of another network with associated variable direct current source. In this way, horizontal scanning is provided in addition to vertical scanning. In another embodiment, a variable current is passed through a radiating element 50, Fig. 4, whereby its electrical length, and consequently its resonant frequency, may be adjusted.
