Filed: 1933-05-09
Abstract: 421,333. Partly electromagnetic switches. SATCHWELL, L., Farnham Road, Slough, Buckinghamshire. May 9, 1933, No. 13514. [Class 38 (v)] [See also Groups XXIX and XI] A device for controlling an oil burner comprises an armature 3 pivoted at 3a and moved towards an electromagnet 2 by a cam 12 operated by a lever 11. The armature is held near the electromagnet by friction between the cam 12 and an adjustable inclined plate 13. This movement opens a fuel supply by opening a valve 5 or starting of a motor and may also close a switch 4 to start a blower. A thermal switch is arranged in the frame or flue and energizes the electromagnet 2 thereby attracting the armature and permitting the cam to fall to its original position. Failure of the flame causes the electromagnet to be de-energized releasing the armature closing down the burner. The thermal switch may be in series with a pressure or thermal switch in the boiler to close down the burner upon excessive temperature or pressure. A switch 15 is operated by a cam 16 on the armature and is in series with the thermal switch so that the electromagnet cannot be energized until the armature 3 is actuated by the cam 12.

Title: Improvements in or relating to communication systems employing compandors
Inventor: NORMAN PETER
IPC: H03G11/02
Filed: 1960-04-20
Abstract: 874,701. Automatic volume control. STANDARD TELEPHONES & CABLES Ltd. April 20, 1960, No. 13777/60. Class 40 (4). [Also in Group XL (c)] The effective transmission equivalent of a channel between an instantaneous amplitude compressor and expander having inverse networks is chosen to give the compressor and expander complementary characteristics, temperature control devices being provided at each end of the channel to compensate for changes in the effective transmission equivalent arising from the use of temperature dependent non- linear resistors in the compression and expansion networks. In a two-way carrier system the transmit channel comprises a compressor as shown in Fig. 2 with shunt impedances 24, 25 across the output of a transistor 22. Output from the compressor feeds a modulator bridge 57 having a local oscillator 9, as shown in Fig. 4. The receive channel comprises an amplifierdetector with the two transistor stages 67, 68, and a full-wave detector 69, 70, as shown in Fig. 4. Automatic gain control is effected by varying the base-emitter impedance of stage 67 by a rectified signal fed back from the detector. The output of the detector over terminals 89, 90 feeds an expander, as shown in Fig. 3, with an expansion network 43, 44, in the emitter circuit of transistor 41, the output of which is shown connected to part of a hybrid 46. Temperature compensation is effected from a potential chain 59, 60, 61, 62; 62 being a block thermistor with a negative impedance coefficient and a Zener diode 64 biased into breakdown stabilizing the voltage across the chain, see Fig. 4. Separate resistors 65, 66 supply bias to modulator 7 and the amplifier detector to govern the modulation index and the degree of automatic gain control. The compression network 24, 25, the expansion network 43, 44 and the thermistor 62 at a terminal station are mounted together and should the temperature at a station increase the compression network adds attenuation which is compensated by a decreased bias over lead 17 which restores the modulation index in bridge 57. The level of the transmitted carrier wave is thereby reduced, but operation of automatic gain control restores the transmission equivalent at the far end of the channel before the expander is reached. With temperature increase the expansion network adds amplification which is compensated by reduced bias over lead 18 which stabilizes gain at a lower level in the automatic gain control circuit. The compression and expansion networks are of the kind described in Specification 832,863. The invention may be applied to a voice frequency system.
