Title: Circuit arrangement for producing trains of sinusoidal oscillations
IPC: H03K3/78
Filed: 1941-12-19
Abstract: 569,339. Generating high - frequency oscillations. BRITISH THOMSONHOUSTON CO., Ltd., and MYNALL, D. J. Dec. 19, 1941, No. 16433. [Class 40 (v)] A circuit for producing trains of oscillations comprises a valve with an inductance in the plate circuit coupled to a coil having an intermediate point at fixed potential and associated with a crystal which when energized from the inductance oscillates to feed an amplifier. The feed to the amplifier is such that the exciting oscillations in the inductance are not transferred to the amplifier through the self capacity of the crystal and the whole arrangement is such that each train of oscillations is produced from the energy stored in the inductance when an impulse renders the valve non-conductive. As shown, a negative feed-back is taken by winding 20 from the output of the amplifier 13 and applied to the suppressor grid of the valve 3 having the inductance 6 in its anode circuit. The feed-back is operative on the removal of the negative voltage impulse and is effective to damp out each train of oscillations excited in the crystal. The shunt capacity of the crystal 10 is balanced by condenser 11, but a partial unbalance may be used to build up the beginning of each train of oscillations with substantially zero time lag. The inductance 6 may be tuned by condenser 7 to the frequency generated and the build up time of the oscillations in the tuned output circuit of the valve 13 may also be reduced by injecting energy into the circuit by utilising the sudden change in current flowing in the cathode resistance 19 common to both valves at the commencement of a train initiated by the negative voltage impulse. Frequency selective circuits may be used in the feed-back circuit alone and aperiodic circuits may be used in the valve anode circuits. The feed-back voltage may be taken through a condenser instead of through a transformer and may be fed to the control grid of the valve 3.

Filed: 1926-06-30
Abstract: 278,085. Marks, E. C. R., (Cameron Machine Co.). June 30, 1926. Winding webs.-In a web-winding apparatus, particularly for winding paper as it is delivered from a paper-making machine, the winding-shaft is initially supported out of contact with the main winding-drum and driven by a change speed gear actuated by the accumulation of material on the shaft, the speed of the winding-shaft being initially higher than normal to take up slack in the web and being gradually educed to normal. As applied to a winding-apparatus such as described in Specification 278,083, in which the winding-shaft 19 is initially supported in pivoted arms 17 so as to be out of contact with the main winding-drum 10 and in contact with an auxiliary winding-device 14. the device 14 is in the form of a roller extending throughout the length of the shaft, 19 and driven by a belt 15 passing round conical pulleys 100, 101. A beltshifting rod 102 is engaged by the vertical arm 103 of a bell-crank lever, the horizontal arm of which is in the path of an arm 104 on one of the arms 17. As the material accumulates on the shaft 19, the arms 17 are turned on their shaft 18 and the arm 104 actuates the bell-crank lever to move the belt 15 so as gradually to decrease the speed of the roller 14. The arrangement is such that when the material on the shaft 19 contacts with the drum 10, the speed of the roller 14 is equal to that of the drum 10.

Abstract: 1494302 Measuring weight MAATSCHAPPIJ VAN BERKELS PATENT NV 23 April 1976 [2 May 1975] 16519/76 Heading G1G Weighing apparatus comprises a transducer 11 which produces signals related to the weight of an article, the weight values being related to the signal values according to a mathematical function characteristic of the transducer, data processing means 26 to receive the signals, to handle the signals in a manner simulating a polynomial expression of the function in the form a 0  + a 1  S + a 2 S<SP>2</SP> + a 3 S<SP>3</SP> +- -- - - + a n S<SP>n</SP> in which a 0 , a 1 , a2, a 3 , --- an are constants and S is a signal value, and to sum the terms of the expression, and read-out means connected to the processing means to indicate the sum of the terms as a weight value. As shown in Fig. 1, the transducer is of the type having vibratable strings, the signal values being in terms of frequency. The processing means consists of multipliers 31, 32, 33, adders 35, 36 and 37, and arithmetic units 43, 44, 45 and 46 for introducing the constants a3, a 2 , a 1  and a 0 . Before using the apparatus, the correct values for a 0 , a 1 , a 2  and a3 must be determined for the particular transducer. To do this, the values of a 0 -a 3  are arbitrarily chosen and four known weights are put on to the apparatus in turn. From the four equations thus obtained the values of a 0 -a 3  may be determined. If the processing means is a micro computer this is done automatically. Otherwise it is done manually and a control 52 is used to put the correct values in units 43-46. These values may be compensated by signals from a temperature probe 54, a gravitational probe 55, and a vibration probe 56. The transducer 11 may consist of a single string. In the case of the two strings shown, the processing means in the form of a microprocessor may count the number of vibrations with frequency f 1  of one string 14 over short periods of time during which the other string preforms a given number, e.g. 16, of vibrations. This process is repeated frequently e.g. 400 times and the single results obtained are added up and processed further in the manner already described.
