Title: Improvements in or relating to arrangements for controlling switches or contacts forcurrents of high strength
IPC: H01H33/00
Filed: 1955-01-31
Abstract: 774,228. Switching systems. UHDE GES., F. Jan. 31, 1955 [Jan. 29, 1954], No. 2887/55. Class 38 (4). A switch 3, having main contacts 2 for shortcircuiting an electrolysis cell upon failure of the supply to an electric motor 45 driving a conveyer 46 for circulating mercury in the cell, is actuated by a compressed air servomotor 12 controlled through a main valve 14 and pilot valve 34 from a " no-volt " relay 49 energized from the motor terminals and provided with change-over contacts. These contacts control, respectively, the energization of a winding 36 for actuating pilot valve 34 and a winding 56 for releasing a locking device 4, 5 by which the switch is held closed, the relay contacts also being in series with auxiliary contacts 58, 62, respectively actuated by the switch 3. The switch also operates a further contact 95 controlling lamps 96, 97 for indicating the condition of the switch. Under normal conditions the relay contacts, the valves and servomotor piston and in the positions shown. Upon de-energization of relay 49, winding 36 is energized over contacts 60, 62 and operates the pilot valve 34 which admits compressed air from a reservoir 19 to a space 37 about the conical head 16 of inain valve 14 (vented to the atmosphere on its lower face through a valve 41 held open by a cam 43 on the piston rod 7 of the servomotor). The main valve is thus caused to descend in its cylinder to close an exhaust port 30 for the servomotor, to which air is now admitted through pipe 13. The piston of the servomotor operates the switch 3 which latches in by the device 4, 5, prepares a circuit for the release winding 56 at contact 58 and opens contact 62 to de-energize winding 36. Cam 43 allows valve 41 to close at the end of the stroke of the servomotor so that the air pressures on the two sides of the main valve 14 equalize and the valve closes under the action of a spring 17. When the service to motor 45 is restored, relay 49 reverts to its initial condition so that winding 56 is energized over contacts 53, 58 to release the locking device 4, 5. The switch 3 thus opens under the action of a spring 94, whilst a spring 11 returns the servomotor to its initial position.

The slides 13 guide a drop hammer 18 which may be raised by gripping rollers 19 rotated by a mechanism 20, each roller having a longitudinal recess which when opposite the hammer releases it to drop on an anvil 21 which may contact a tube 10 to be hammered into the soil through a guide 9. A measuring head 22 normally positioned on a support 26 may be connected by pins 29 to the slides 13 and interposed between the anvil 21 and the tube 10 when measuring the resistance to driving or extraction by steady hydraulic forces. In order to carry out measurements, the head must first be picked up from the support 26, Fig. 2, by operating the rams 15 to tilt the frame 1 and its arms 24 about pivots 23, Fig. 4, the hammer 18, anvil 21 and head 22 being all entrained whilst the frame is so tilted. The frame is then tilted back again to its vertical position and the rams 15 and so on lowered until  the head 22 rests on the tube 10 to be hydraulically driven or extracted, the hammer 18 not being used in this operation. The frame 1 is tilted to its angled position each time it is necessary to add a tube 10 or disengage the head 22.

The surface of the product may be carburized by passing the gases of the non-oxidizing atmosphere through a volatile hydrocarbon before their admission to the furnace.
Patent GB-390178-A (GB)
Title: A method and apparatus for the purpose of controlling electrical energy
IPC: H01F27/24
Filed: 1931-09-30
Abstract: - 390,178. Inductances ; sound emitting and receiving devices. WHEATLEY, C. H. P., 21, Linton Crescent, Hastings. Sept. 30, 1931, No. 2998. [Class 37.] Heat energy is applied to a magnetic metal element forming or situated in a magnetic circuit to vary its permeability for the purpose of causing changes in the inductance of a winding producing magnetism in said circuit. This change in inductance is utilized to control circuits in various ways. In the form shown in Fig. 4, the inductance of the coil 3 included in a tuned circuit 10 is varied by varying the permeability of the magnetic circuit 1 by varying the heat supplied to the element 4 from the source 16, and the change in inductance varies the frequency of the tuned circuit relatively to that of the supply 11 and so regulates the transfer of power to the circuit 13. An adjustment of the permeability of the circuit may be made by means of a second heating element 17 similar to the element 4 and fed from the supply 11. In the form shown in Fig. 5, the change in inductance varies the frequency of the circuit of the valve 18 and may be used to regulate by this means the transfer of energy from the valve circuit to the circuit 13, the amount transferred in both these arrangements depending on the fluctuations of heat applied to the element 4. In the form shown in Fig. 6, heat is applied electrically to the unit 19 fed in series or parallel with the coil 3, and upon a decrease in temperature the choking effect of the coil 3 is varied to vary the current passing through the element 19 which is thereby maintained at a substantially constant temperature. In the form shown in Fig. 7, the variation of temperature varies the choking effect of the coil 3 and causes the diaphragm 21, which may be polarized, to vibrate. The diaphragm may carry current or may be replaced by any element susceptible to magnetic variations. Instead of varying the quantity of heat supplied to the element 4, in the arrangement shown in Figs. 4, 5, and 7 it may be heated uniformly and cooled in a fluctuating manner, and this would enable the apparatus such as is shown in Fig. 4, but without the second element 17, to be used as a microphone, sound waves being caused to impinge on the element 4 to vary its temperature and produce corresponding fluctuations in the circuit 13. When the heated element is constructed of fine-gauge wire and carries a modulated high-frequency current, the element responds to temperature changes according to the frequency of the modulation, but not to the high frequency, and the apparatus thus acts as a detector of such energy, and audibly in the case of the arrangement shown in Fig. 7. The heated element, with or without the coil 3 &c., may be enclosed in a non- magnetic container filled with hydrogen or other inactive gas. The coil 3 may surround the central yoke of a magnetic core which has projecting spoke-like limbs around which the wire forming the element is wound, a heatresisting baffle being interposed between the wire 4 and the coil 3.
