Abstract: 976,128. Microwave Interferometry. COMMUNAUTE EUROPEENNE DE L'ENERGIE ATOMIQUE EURATOM. Nov. 2, 1962 [Nov. 3, 1961], No. 41623/62. Heading G1N. [Also in Division H3] The electric lengths of two channels are compared by passing microwave energy along each channel and applying the outputs to a mixer which produces two currents, the amplitude difference of which is a measure of the phase difference between the waves received by the mixer, the difference between the currents being used to control a balancing member in or connected to at least one of the channels to substantially cancel out the phase difference, an integrator being provided to integrate the control current to the member and to display continuously the variations of electrical length. The method is applied to the determination of the refractive index of a gas when it is ionised. In a first embodiment a chamber 8 containing a gas sample is placed in one channel 1 of a waveguide system. Channel 1 and a parallel channel 2 are fed from a common micro-wave generator 3 and are connected to mixer 7, preferably a magic- T in whose magnetic and electric arms 20, 21, which include square-wave detectors 15,16, the sum and difference waves are set up. The outputs are applied to a differential amplifier 12 and power amplifier 13 to control a phase shifter 11 in channel 2. Integrator 14 continuously displays variations in the phase of the wave from channel 1, relative to the original reference phase in channel 2. In a modification the second channel is much longer than the first and the output from amplifier 13 is used to adjust the frequency of source 3 to nullify the phase difference.
Patent GB-417562-A (GB)
Abstract: 417,562. Sheet delivery apparatus. HESSER MASCHINENFABRIK AKT.- GES., F., 99, Olgastrasse, Cannstatt, Stuttgart, Germany. April 7, 1934, No. 10537. Convention date, April 19, 1933. [Class 100 (i).] A device for delivering cardboard or like blanks in counted batches from a punching or other machine comprises a series of containers each advanced in steps equal to the thickness of one blank by one mechanism until filled, and then given an accelerated movement by a second mechanism to bring the succeeding container into delivery position. The containers 3, Fig. 2, each of which is divided into compartments 4-7 to receive four side-by-side blanks, are supported at their ends on endless chains 21-24. Shafts 25, 26 carrying the lower sprocket-wheels for the chains are coupled by worm-gearing 27, 29 to a cross-shaft 31 normally rotated by the engagement of a pawl 50 on an oscillating arm 51 with a ratchet-wheel 35 fixed to the shaft 31 so as to advance the container receiving the blanks by steps equal to the blank thickness. An arm 96 coaxial with the arm 51 and connected thereto by a bar 95 rotates, through ratchet-and-pawl mechanism 97, a wheel 43 freely mounted on a stub-shaft 44 coaxial with the shaft 31. In frictional engagement with the wheel 43 is a disc 42, to the hub 41 of which is fixed one end of a spiral spring 38, the other end of the spring being attached to a casing 37 normally prevented from rotation by the engagement of a pawl 65, Fig. 3, on an arm 68 pivoted to the framing with one tooth 60 of a series of three teeth 60, 61, 62 on the periphery of a disc 36 fixed to the casing 37. The frictional coupling between the parts 43, 42 causes the spring to be wound up. When one of the compartments 3 has been filled, a projection 90 on the ratchet-wheel 35 engages a projection 91 on the arm 68 and lifts the pawl 65, thus allowing the disc 36 and casing 37 to rotate under the action of the spring 38 until the pawl 65 engages the next tooth 61 on the disc 36. Three radial spring-controlled bolts 85, 86, 87 are mounted on the disc 36, and for each movement of the disc 36, one of these bolts engages a tooth 34 on a disc 33 fixed to the disc 35 and thus gives a rapid movement to the shaft 31 and therefore to the containers to move the filled container away from and the succeeding container into delivery position. Subsequently the disc 35 is rotated by the ratchet-and-pawl mechanism 50 to lower the container while the blanks are being delivered thereto and until the projection 90 engages the projection 91 on the arm 68 when the cycle of operations is completed by the rapid movement of the disc 35 and the containers. The pawl 65 is slidably mounted on the arm 68 under the control of a spring 72, so that it yields when engaged by one of the teeth 60, 61, 62, and thus prevents shock. Each container 3 has brackets 15, 16 at its ends which rest on ledges 17, 18 fixed to the chains 21-24, and is secured to the ledges by bolts 100, 101 pressed outwardly by a spring 106. Finger-pieces 102, 103 are provided on the bolts for releasing them.
