Title: Methods and apparatus for measurement of stresses and the main components influencing them such as temperature, pore-water pressure, strains as well as deflections in concrete or like constructional material
IPC: G01B13/00
Filed: 1957-02-20
Abstract: 857,222. Measuring stresses; strains, and pressures. GLOTZL, F. Feb. 20, 1957 [Feb. 20, 1956], No. 5775/57. Class 106 (2). [Also in Group XX] Apparatus for measuring mechanical stresses or mechanical values, such as temperature, pressure or strain, which can be converted thereto comprises a valve-type pick-up 2 built into part of a structure 1 in which the stresses or values are to be measured, a pipe 7 supplying a pressure medium, and a pipe 6 returning the medium to its supply source, the pick-up 2 being constructed as an hydraulic pressure-relief valve V so that the mechanical stress or value being measured controls the pressure at which the valve opens. As shown in Fig. 1 for measuring the stress in a concrete building, a resilient capsule 2 is built into the concrete during construction and provided with inlet and outlet pipes 7, 6. Pipe 7 enters the capsule at an arbitrary but not central point, and pipe 6 enters at the centre of the lower diaphragm 4 the central portion of which is accurately ground to bear against an accurately ground surface on the upper diaphragm 3 and from a valve V. In use, liquid is pumped through inlet 7 until the pressure inside the capsule 2 equals the external pressure due to the stress in the concrete. At this point the valve V opens and excess liquid returns by pipe 6. Thus, the maximum pressure recorded on a pressure recorder 10 gives a measure of the stress at that time. This operation may be repeated at any desired interval. Fig. 3 shows the apparatus used for temperature measurement. A bimetallic tube 21 is held in a fixed frame 20, the base 25 of the tube being freely movable and having a ring 23 secured to it. Thus, a valve V similar in action to that in Fig. 1 is formed by the ring 23 and the base 26 of the frame 20. The action is as before, fluid being pumped in until its pressure equals the pressure acting on the base of the tube 21 derived from the temperature in the concrete. When this happens, the valve V opens and excess liquid returns via the pipe 6, the temperature being represented by the maximum pressure indicated or recorded at 10. Other embodiments (not shown) describe the measurement of the strain in the building and of the pressure of the water in the pores of the concrete.

Abstract: 1,071,927. A-D converters. STANDARD TELEPHONES & CABLES Ltd. Feb. 12, 1965, No.6168/65. Heading G4H. [Also in Division H3] With a zero input signal, the transistors 62, 66, 70 of the bi-stable stages are conducting and draw current from binary weighted constant current sources comprising transistors 63, 67, 71. A unit quantum input signal sample applied to emitter follower 73 produces current flow through resistor 60 such that 62 is cut off and 61 is turned on so that the current drawn from transistor 63 flows through resistor 60. When the input increases to two quanta, 66 turns off and 65 turns on, and the voltage at the collector of 61 is such as to cause 61 to be cut off and 62 to be turned on. An input of three quanta causes 61 to turn on again, 65 also remaining on. An input of four quanta causes 69 to switch on and draw current from 71, this being sufficient to turn off 61 and 65. For higher levels, 69 remains on with one or both of 61 and 65. The junction between resistor 60 and the collector of transistor 61, and the corresponding points in the other stages, exhibit a voltage/current characteristic which is similar to that of a tunnel diode. A damped oscillatory signal may be superimposed on the input.

Abstract: 491,771. Converting ; supply systems for consumption apparatus. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 28, 1938, No. 6314. Convention date, Feb. 27, 1937. [Classes 38 (ii) and 38 (iv)] An arrangement for supplying a load such as a D.C. load 3, Fig. 1, from an A.C. circuit 1 comprises at least a pair of valves 10, 11 which conduct alternately wherein one of the valves 10 is controlled from an external source 17 and the control potential of the second valve is derived from the circuit of the first valve and consists of a negative potential dependent on the nonconducting portion of the positive halfcycle of anode voltage applied to the first valve, and delays the moment of ignition in the second valve to a point corresponding to that at which the first valve conducts. This negative bias is obtained from a condenser 27 which is charged through a rectifier 29 from a transformer 28 connected across the valve 10, charging current flowing only during the part of the positive halfcycle when the valve 10 is nonconducting. The valve 11 remains nonconducting until this negative bias is balanced by a positive bias injected in the grid circuit from a transformer 30 connected across the valve 11. By suitable adjustment it can be arranged that the valve 11 conducts at the same point in the half-cycle as the valve 10. The control of the valve 10 is through a phase shifting transformer 18 and peaking transformer 16. A threephase arrangement is described in which the third valve is dependent on the second. The Specification states that the arrangement is applicable to rectifiers, inverters, frequency changers and arrangements for interconnecting circuits of the same frequency. The Specification states that the phase shifting transformer 18 may be automatically adjusted in dependance on circuit conditions.
