Title: Digit sending electric switch for telephone use
IPC: G05G9/047
Filed: 1979-11-20
Abstract: A single-button telephone "dialler" has a central rod-like member (6, 10, 4) with a button 1 on its upper-most end and a lower portion of springy wire 6, and is surrounded by a set of contact pairs (8), engageable by a portion of insulating material (10) for contact operation. Also surrounding the rod there is a locating member 3 with a set of slots 9 radially arranged and each associated with one contact pair. To send a digit the rod is moved sideways into the slot for the digit to be sent until it operates the contact pair (8) to cause digit sending. When the rod is released, the springiness of the wire (6) returns it to rest. In a simplified version the rod also acts as a contact and is mainly of metal to co-operate with single contacts each at the end of one of the slots. <IMAGE>

Title: Defrosting control apparatus
IPC: F25D21/00
Filed: 1980-03-31
Abstract: The accumulation of ice on a surface such as an evaporator fin (2) in a refrigerator unit is detected by a mechanical probe (4) which is moved by a bimetal bender element (8) upon periodic timer-controlled energisation of a bimetal heater (12) so as to pass over the surfaces of an evaporator fin (2).

Title: Electronic peak averaging circuit for a pyrometer
IPC: G11C27/02
Filed: 1981-11-03
Abstract: An electronic peak averaging circuit for a pyrometer viewing the surface of turbine blades in a jet engine includes a peak holding circuit 18 which identifies and holds the maximum value of the sensor waveform over a predetermined interval of time. A tracking filter 12 provides a timing signal to a pulse generator 16 that creates control pulses to dump the peak hold unit at the end of each predetermined interval. A sample and hold unit 24 connected to the output of the peak holding unit is enabled by generator 16 just prior to each dump pulse for the peak hold unit so that the output of the sample and hold retains the peak amplitude of the sensor waveform during the prior predetermined interval. A low pass filter 30 integrates the output from unit 24 to form a final output signal which is indicative of the average peak temperature. <IMAGE>
