Title: Improvements in or relating to voltage measuring instruments
IPC: H03M1/00
Filed: 1967-11-16
Abstract: 1,200,905. Digital measuring instruments; electric calculating apparatus. FAIRCHILD CAMERA & INSTRUMENT CORP. 16 Nov., 1967 [20 March, 1967], No. 52198/67. Headings G4A-G4H. An electric measuring instrument comprises input terminals 14, 15 to which are applied a reference voltage and the unknown input signal, one of the terminals at a time being switched to a voltage-to-frequency converter 18 the output of which may be switched to a first counter 40 giving an output at a predetermined count and means for storing the time taken for the counter to reach the predetermined value when the converter 18 is energized by the reference voltage, and for causing the counter to count for the same period of time when the converter is energized by the input signal. The counting period is stored by time base 44, comprising a counter 46 which counts forwards while the reference signal is connected to converter 18, and backwards while the unknown signal is connected until it reaches zero. For this purpose there are provided ganged switches S-2 and S-3 with four positions A, B, C, D. Switch S-1 has two positions A, B. Firstly switch S-1 moves to position A and switches S-2 and S-3 to position B. Counter 40 counts pulses from converter 18, receiving the reference signal, and counter 46 counts pulses from clock 50. As soon as counter 40 reaches its capacity it sends a signal to the program logic 70 which steps the switches S-2, S-3 to position C, interrupting the counting. Switch S-1 then moves to position B and switches S-2, S-3 to position D so that counter 40 receives pulses from converter 18 controlled by the unknown signal, and counter 46 counts backwards. When it reaches zero a pulse on line 79 causes the logic 70 to step the switches S-2, S-3 to position A. The value in counter 40 then represents the unknown voltage in terms of the reference voltage. Adding.-Values expressed as voltages can be added by a slightly modified apparatus by setting a counting period as before using the reference voltage and then applying the values in turn to the converter 18, the counter 40 being connected to count the pulses without being reset between counting operation so that the counts accumulate. Instead of a single reversible counter 46, two or more counters may be used with coincidence gates between them to give signals when the initial reference value has been reached.

In a radio receiver a wide-band pre-amplifier feeds a number of receiving channels, having different band-pass characteristics, in parallel, their outputs being taken after detection to an output circuit which gives an output corresponding only to the strongest signal thereof. The band-pass characteristics of all the channels are in overlapping relationship and are such that in each channel there is passed a band of frequencies which is passed by all other channels. As described, input to a terminal 1, Fig. 1, is taken to a wide-band amplifier AO which feeds two channels in parallel containing in series, filters F12, F22, amplifiers A12, A22, further filters F11, F21, detectors D1, D2, and output amplifiers A11, A21. The outputs from the channels are taken to an output circuit O of known kind which feeds to terminal 2 from whichever channel is giving the stronger signal. With a signal band of 500 kc/s. centred on 30 Mc/s., F12, A12 may be centred on 27 Mc/s. and F22, A22 may be centred on 33 Mc/s., each with an overall pass-band of 6 Mc/s., F11, F21 being narrow band filters centred on 30 Mc/s. (Fig. 2a, not shown). It is stated that as applied to radar the invention gives particular protection against spot jamming while providing protection against wide bandwidth noise or jamming equivalent to that of a C.F.A.R. (constant false alarm receiver). In an alternative arrangement, Figs. 3a, 3b (not shown), the receiving channels are provided with band-stop filters so arranged that in each channel the wanted signal band is passed but that with all channels in parallel the stop bands are contiguous and extend on each side of the signal band.

Abstract: 1293761 Centrifugal separators THOMAS BROADBENT & SONS Ltd 7 Nov 1969 [16 Nov 1968] 54475/68 Heading BID In order to prevent solid particles, e.g. sugar crystals, discharged from the lip 1 of the rotating basket 2 of a centrifugal separator, from being fractured at the wall of an annular pneumatic zone 30 surrounding the lip, jets of air (or other gas) from toroidal manifold 5 are directed into the zone 30 by vanes 6 in passage 4 so as to reduce the radial component of velocity of the particles. Pressurized air is introduced into manifold 5 from duct 32. If desired, the air may be heated to assist in the drying of the particles separated by basket 2. The casing of the annular pneumatic zone is of volute configuration, the deepest end of the volute leading to a conveyor duct 34 for removing the separated particles from the machine. The apparatus shown is particularly suitable for 'high velocity particles', for the discharged particles are made to move in a direction opposite to the direction of rotation of basket 2. An apparatus which is suitable for 'low velocity particles' is described: this has a shallower annular casing, and the vanes form an obtuse angle with the tangential direction of flight of the particles so as to enhance their velocity in the direction of rotation of the basket. The separation of polystyrene balls is referred to. Curved vanes may be used. An apparatus is described wherein, the air jets are arranged to have a velocity substantially equal and opposite to. that of the particles discharged from the lip of the basket. The velocity of the particles is then reduced so that they fall freely under gravity.
