Abstract: 613,443. Flue dampers. AIR HEATING, Ltd., and BIGGART, R. J. C. Jan. 12, 1946, No. 1156 [Class 51(i)] In a thermostatically-controlled flue damper for stoves &c., the damper 11 is of slightly greater length than the diameter of the flue 10 and is pivoted on a transverse shaft 13 so as to bear against a beading 15 on the upper end of a bi-metallic bar 16, 17 which is carried by a bracket 20 bolted to a cross member 19, the latter having screw-threaded ends fitted with wing nuts 24 by which the position of the member 19 and thus of the bar 16, 17 may be adjusted.

The liquid crystal composition has a critical frequency fc such that at lower frequencies, the dielectric anisotropy of said composition is positive and at higher frequencies is negative, fc lying between the low frequency and high frequency components in the output of said circuit. The arrangement of the device is such that a selected picture cell in said display element can be turned off by applying the high frequency component of said output. Other embodiments include a device in which a dichroic dye is incorporated in the composition and an embodiment which contains means for detecting the temperature of the liquid crystal composition.

Patent GB-2040464-A (GB)
Title: Measuring Liquid Level
IPC: G01F23/26
Filed: 1979-01-05
Abstract: Apparatus for determining the liquid level in a non-metallic tank, includes a pair of parallel plates 12, 13 secured to the outside of the tank 11 to avoid contact with the liquid inside it. The plates have a generally vertical orientation so that as the liquid rises in the tank, an increasing area of the plates is adjacent to the liquid. The change in capacitance between the plates as a function of liquid level is utilized to generate an electrical signal indicative of liquid level. The problems caused by highly viscous liquids coating the inside surface of the tank and yielding false readings are solved by utilizing a high frequency driving signal, such that the capacitive component of the current between the electrodes is large compared with the resistive component. An oscillator 14 energises one of the plates with a square wave signal and the other plate is connected by a shielded cable 15, 17 to an amplifier 16, feeding a meter 20. <IMAGE>

Title: Integrated circuit including a resistive element
IPC: H01L27/08
Filed: 1979-01-23
Abstract: An integrated circuit includes a resistive element in which a high- sheet-resistivity zone (11) connects two spaced-apart zones (12, 13). A conductive field plate (15) overlies the high- sheet-resistivity zone (11) and is insulated from it by a composite insulating layer (16, 17). The field plate (15) is connected to a node of the circuit and stabilises the resistance of the element by inhibiting depletion or inversion of surface regions of the high-sheet- resistivity zone (11). A suitable node is one (13) of the spaced-apart zones, preferably the one which in use is the more negative, in the case of a P-type high- sheet-resistivity zone. The invention is particularly applicable to linear integrated circuits where stable resistances are required. <IMAGE>

Title: Wavelength Stepping in a Dual Beam Spectrophotometer
IPC: G01J3/06
Filed: 1979-03-05
Abstract: A dual beam spectrophotometer includes a radiation chopper 5 and a monochromator 3 which includes a diffraction grating driven by a stepper motor. The chopper 5 includes a gate pulse generator 24 which produces gate pulses GS and GR which correspond to periods during which radiation from the source 2 passes through a sample cell 19 and a reference cell 14 respectively. A stepping motor drive circuit 134 produces pulses to step the stepper motor which are synchronised with the chopping cycle by means of the GR and GS pulses. The stepper motor is arranged to step an equal number of times in each half of a chopping cycle, so that disturbances caused by stepping can be filtered out. A further condition which is preferably satisfied is that the first pulse of a sequence should start in the opposite half of the chopping cycle from that in which the first pulse started in a previous chopping cycle. At low stepping rates the motor will step twice in one chopping cycle and then pause for several cycles before again stepping twice. <IMAGE>

Patent GB-2024472-A (GB)
Title: Segmented error-correction system
IPC: H03M13/19
Filed: 1979-06-01
Abstract: In a data processing error control system for named data, a parity check matrix and apparatus for using same provides for single error correcting of the data word and for multiple error detecting in both the data word and data name. The parity check matrix and apparatus utilize two additional parity check bits (over that required by a system using a prior art SEC/DED Hamming code) to provide protection against single bit errors, eight contiguous bit errors (i.e., hardware stuck at logical one or logical zero for the whole eight contiguous bits), similar four contiguous bit errors, and faults covering the entire data name field (which could occur, for example, if a wrong data word was fetched from memory). The parity check matrix is segmented and mated to the error correctional requirements and prevalent error modes of each field being protected. In encoding, parity check bits are generated for the combined data word and associated data name field. In decoding, an overall parity check of the check bits, data word and data name is performed for distinguishing between odd and even errors. Further, the parity check matrix is invoked to generate a parity checking number for addressing a decoding table circuit (realizable as a ROM) which in turn provides the error bit location for single bit correctable errors. Given the error bit location a correction circuit corrects (i.e., complements) the detected single erroneous bit in the data word or in the generated parity check bits.
