Title: Electrical heating circuits and protective circuits for use therewith
Inventor: WALKER ROBERT HOLLIS
IPC: H05B3/34
Filed: 1983-08-16
Abstract: A heating circuit, such as for an electric blanket, comprises a heater conductor 14 supplied with AC power through a thermal switch 16 which is in thermal relationship with resistors 20 and 24. Resistors 20 and 24 are connected in series with a sensing conductor 22 through capacitor 18 and rectifier 26. Sensing conductor 22 is wound around and along the heater conductor 14 but separated therefrom by temperature-sensitive insulating material 28. Under normal conditions, rectifier 26 blocks current flow through sensing conductor 22 during alternate half cycles and the charge on capacitor 18 blocks such current flow during the other half cycles. If blanket overheat occurs, however, the impedance of layer 28 falls, either locally or generally depending on the type of overheat, and current can now flow through either or both of resistors 20 and 24, depending on the position of the overheat. Resistors 20 and 24 are positioned in thermal relationship with the thermal switch 16 so that when one or both of them carries sufficient current and becomes sufficiently heated, the thermal switch open- circuits. <IMAGE>

Inventor: SANDER WENDELL
IPC: G11B20/10
Filed: 1987-08-25
Abstract: A disc drive controller has read post compensation which corrects for peak shift effects on discs with insufficient precompensation. The data is recorded in Manchester (MFM) format and read into circuitry including SCT counter (451) which loads parameters representing a cell with a short-cell (2 unit) following it and LCT counter (453) which loads parameters representing a cell with a long cell (3 or 4 unit) following it. Bound detector 455 counts the number of pulses between transitions and shift registers (457, 459) store the number of pulses generated by the respective counters to enable the bound detector to generate peak shift compensated pulses. The controller has a programmable parameter scheme which makes it possible to read and write 3 1/2 inch variable and fixed speed drives, as well as standard 5 1/4 inch drives. Additionally, there is a plus/minus rate multiplier to correct for symmetry and frequency errors. The use of half clock circuits to provide half clock resolution in the signal being written to and read from the disk is provided with the capability of operating at continuously variable clock speeds and data rates dynamically programmable by the computer. <IMAGE>
