Title: Improvements in apparatus for measuring a physical value depending on another value or on a plurality of other values
IPC: G01F1/50
Filed: 1924-01-29
Abstract: 237,305. Roucka, E. Jan. 29, 1924. Tell-tale apparatus.-Comprises apparatus for measuring a physical value which is a function of one or more other physical values, the values co-operating with a periodic auxiliary value to set up a condition of equilibrium in a lever system at which an electric impulse is transmitted from a sending to a receiving station, which, with the assistance at the receiving station of a member moving in synchronism with the auxiliary value effects an indication or registration the instant of which within each period represents the amount of the measured value. In the particular example described, the physical values concerned are flow of steam per unit of time, which is a function of the pressure difference in opposite sides of a constriction in a pipe, and of the temperature of the steam. A pressure resistance device comprising a U-tube 10 containing mercury and mounted on a knife edge 12 has its limbs connected by pipes 8 to a conduit 2 in which steam is flowing at points above and below an obstruction 4 in the conduit. A connection 38 leads from above the obstruction to a cylinder 32 and allows the pressure in the conduit 2 to act on a piston 34 against the influence of a spring 36. A temperature responsive device 76 below the obstruction 4 is connected by a pipe 74 to a cylinder 72 and causes a piston 70 to move against the influence of a spring. The pressure-gauge device 10 is connected by a link 16 to a lever 18 having a roller fulcrum 26 moved by the piston 32 and carrying a screw 84. The lever 18 is steadied against lateral movement by a spring strip 20. The other end of the lever 18 is connected by a link 24 to one end of a lever 40 having a roller fulcrum 42 moved by a cam 50 driven by a constant speed motor 54. The other end of the lever 40 is connected by a link 56 to one end of a lever 58 having a roller fulcrum 64 moved by the piston 70 and acted upon at the other end by an adjustable spring 78. A pen 110 is reciprocated across a travelling strip 114 by a cam driven from a constant speed motor 100 supplied from the same mains 116 as the motor 54. The pen 110 is pressed against the paper by means of an arm 96 moved by an electromagnet 92 in circuit with a source of power 90 and with a switch 86, 88 whenever the lever 18 tilts so that the screw 84 closes the switch.

Title: Improvements in methods and equipments for induction heating
IPC: H05B6/04
Filed: 1961-01-20
Abstract: A unidirectional polarization field is applied to a ferromagnetic workpiece throughout the first phase of an induction heating process which includes two phases for the preferential heating of two different portions of the workpiece, the second phase beginning with the portion to be preferentially heated during this phase being at a temperature below the Curie point. The different portions may be a tooth and a root of the teeth of a gear pinion undergoing surface hardening and the polarizing field may be saturating or non-saturating.  The two phases may be carried out at the same frequency or at different frequencies. In the latter case a radio frequency is employed in the second phase and a lower frequency in the first phase.  The effect of the polarizing field is to reduce the apparent permeability of the workpiece during the first phase.  An apparatus for carrying out the process is described (see Group XI). Specification 890,571 is referred to.

Title: Control circuit for causing a main circuit to fail to a safe condition
Inventor: MILLAR RICHARD ASHWORTH
IPC: H03K17/22
Filed: 1962-01-23
Abstract: 1,034,812. Transistor pulse circuits. BRUSH ELECTRICAL ENGINEERING CO. Ltd. Jan. 11, 1963 [Jan. 23, 1962], No. 2531/62. Heading H3T. A control circuit which fails to a safe condition when any component in the control circuit fails comprises an energy storage element which is periodically charged from a D.C. supply and periodically discharged so as to produce D.C. output current of opposite polarity to current from the supply. In Fig. 3, when transistor T is non-conducting the capacitor C charges through resistor R and rectifier MR1. Upon the transistor being rendered conducting the point X becomes positive with respect to the upper line of the supply source B and the rectifier becomes non-conductive so that the capacitor discharges through the load (e.g. a relay coil). The load current is controlled by the signal voltage at the input of the transistor by biasing the transistor so that it no longer conducts or so that it always conducts (in either case the D.C. current flow in the load is terminated), by varying the time during which the transistor is conductive relative to the non- conductive period or by changing the relative impedance of the transistor in its " on " and "off" condition. If any of the components fail by an open or a short circuit no D.C. current is applied to the load. The transistor may be replaced by a thermionic or ionic device or by a magnetically or mechanically operated contact or a combination of these. In Fig. 2 (not shown) when the switch 2 is conductive a current builds up in inductor L so that when the switch is opened a back E.M.F. is generated at Y of opposite polarity causing diode MR1 to conduct and allow current to flow from the inductor to the load. A " freewheeling " diode MR2 is provided so that if diode MR1 becomes permanently conducting the load is short circuited so that as in this instance the load is inductive failure of MR1 causes A.C. current flow in the load.
