Patent EP-0244268-A2 (EP)
Inventor: DI CESARE JOHN MARIO
IPC: G05F1/66
Filed: 1987-05-01
Abstract: A power control device for controlling power to resistance heaters (2, 20) in a chamber (1) in which the temperature is to be controlled and a pressure tank (19) uses a microprocessor (7) adapted to provide a temperature setting means (8) which inputs a desired temperature. The power consumed by the heater in the chamber is measured by a circuit (10, 12, 11) and compared with a desired power level calculated by the microprocessor. Temperature measuring means (4) in the chamber (1) provides a signal compared with the desired temperature. The microprocessor synchronizes an A.C. current signal and allows a triac (17) to fire for a calculated portion of each phase of A.C. current to provide power to the heater in the chamber such that the temperature therein is accurately controlled and maintained. When subambient temperatures such as -150°C are required the microprocessor controls another triac (28) in a similar manner to control power to the heater in the pressure tank which contains coolant for feeding to the chamber. The pressure in the tank is monitored and compared with a desired pressure level calculated by the microprocessor.

Abstract: An air cycle cooling system (10) includes a compressor wheel (15) which delivers air for expansion by a first turbine wheel (13). Air expanded by the first turbine wheel is used to extract heat from a heat load by way of load heat exchanger (19). After leaving the heat exchanger (19) the air is further expanded and cooled by a second turbine wheel (14) and is then supplied to load heat exchanger (22) to extract heat from a heat load. 
     The system allows the use of high overall pressure ratios without sub-zero turbine outlet temperatures obtaining.

Title: Phase detector
Inventor: BRIDGMAN ROGER FRANCIS
IPC: H03D13/00
Filed: 1987-06-18
Abstract: A phase detector for indicating the magnitude of a phase difference between two electrical signals applied to it, is provided with means for introducing a deliberate phase shift into one of the signals so that the measured phase difference never closely approaches 0° or a multiple of 360°. The detector is capable of providing a smooth output signal over a very wide range of phase difference which can exceed many multiples of 360°. Furthermore, the phase comparator is never required to perform measurements in those regions of least accuracy close to zero phase difference.

Abstract: A method and apparatus is disclosed for correcting up to two byte errors in encoded uncorrected data in records of a predetermined length. As illustrated, the records are subblocks of a block in a multi-level error correction code format. The data is read from a storage device and corrected by decoding and processing four syndromes of error (S₁, S₂, S₃, S₀) that are generated by means disclosed in the prior art. These syndromes are decoded in response to uncorrected errors in any one record by computing vectors (P, Q, and R), which are functions of the four syndromes. Binary numbers (u and v) are then determined from these vectors by table look-up to enable calculation of one value (d) from the sum of the binary numbers for determining error locations. Another value (t), mathematically related to the one value, is then determined by table look-up and the error location values (y and z) are determined by calculating the offset of binary numbers (u,v) from the other value (t). Finally, error patterns (E y  and E z ) are determined by table look-up.

Abstract: The vertical drive pulse generator comprises a gate (59) passing a vertical synchronizing signal included in received video signals in response to a control signal, a counter (60; 360) counting a clock signal (CL) of 2f H  (f H : a frequency of a horizontal synchronizing signal) to generate a plurality of timing signals, a 50/60 decider (65; 365) deciding whether the vertical synchronizing signal from the gate is of the NTSC or the PAL system and a synchronization detector (66; 366) detecting whether the counter is reset in response to the vertical synchronizing signal passed through the gate or by a timing signal outputted by itself. One of the timing signals from the counter is selected in response to the outputs of the 50/60 decider (365; 65) and the synchronization detector (66; 366) and applied to the gate, thereby to make the gate pass a signal only when the control signal is received. When the 50/60 decider indicates that the arriving vertical synchronizing signal is of the NTSC system, the gate circuit (67; 367) opens during a period of 224 H to 296 H (H: a horizontal scanning period), while detecting the PAL system to open the gate during a period of 268 H to 356 H. when a step-out detection circuit (66; 366) detects a step-out state, the gate opens during 224 H to 356 H. The vertical drive pulse generator   further comprises a phase comparator (422) which selects and generates a signal for defining a gate period of either 260.5 H to 264 H for NTSC system or 310.5 H to 314 H for PAL system.
