Title: Improvements in or relating to apparatus for indicating the occurrence of icing conditions in a gas stream
Inventor: ROBERTSON ERNEST OWEN
IPC: B64D15/20
Filed: 1951-08-08
Abstract: 700,641. Meteorological apparatus. NAPIER & SON, Ltd., D. July 31, 1952 [Aug. 8, 1951], No. 18691/51. Class 97(3) [Also in Groups XXXIII and XXXVIII] Apparatus for indicating the occurrence of icing conditions in a stream of gas comprises a dynamically balanced rotor arranged to rotate with at least a part thereof in the gas stream and so formed, or provided with apart or parts which can be 'heated to prevent the accumulation of ice thereon, that ice which accumulates on the rotor during icing conditions disturbs the dynamic balance of the rotor, and means responsive to the vibration caused by rotation of the rotor in the unbalanced condition thus produced by such accumulation for indicating the existence of icing conditions. The apparatus shown comprises a body A having a rotor B journaled in a bearing B<SP>1</SP> and in a bearing B<SP>2</SP> which is resiliently supported, by a disc C as of rubber. Rotor B carries blades D<SP>1</SP>, D<SP>2</SP> arranged to be heated by resistance windings D3, D4 connected to the blades and to respective conductors D<SP>6</SP>, D<SP>7</SP> connected to slip rings F, F<SP>1</SP> on the rotor. These slip rings are not normally electrically connected and only one thereof F is in circuit with an electrical generator having its field E<SP>1</SP> fixed to the body and its armature E on the rotor. Thus, when blades D<SP>1</SP>, D<SP>2</SP> are rotated by the flow of air, current is supplied only to slip ring F whereby blade D<SP>1</SP> is heated. If ice forms on the unheated blade D<SP>4</SP>, the consequent dynamic unbalance of the rotor causes the latter to vibrate laterally. Such vibrations are applied by a rod G<SP>1</SP> on the rotor to an electrical pick-up device H of the magnetic or piezo-electric crystal type, the impulses from which are supplied to an amplifier including two relays, in circuit with a power source for indicating and/or de-icing apparatus. When such impulses reach a certain amplitude, one relay is operated and the indicating and/or de-icing apparatus actuated; and, when they reach a higher amplitude, the second relay is operated with the result that a switch J in the body A electrically connects the slip rings F, F<SP>1</SP> and blade D<SP>2</SP> is heated to melt the ice thereon and hence restore the rotor balance. In another form the rotor carries only one blade and a counter-weight is provided in the hub to maintain balance until ice is formed on the blade. The pick-up device may be replaced by a switch.
