Title: Complementary metal oxide semiconductor integrated circuit including a voltage regulator for a section operated at low voltage
IPC: H01L27/092
Filed: 1980-04-03
Abstract: A CMOS integrated circuit includes a high voltage section operable in a range from 3 to 15 volts and a low voltage section which is operated at a voltage corresponding to the sum of the thresholds of a P-channel and an N-channel field effect transistor. This voltage is developed between one of the supply terminals for the circuit and a node which is connected directly or indirectly to the low voltage section and is also connected by way of a voltage regulator, constituted by a transistor which acts as a current sink, to the other supply terminal for the high voltage section. The low voltage section is thereby always operated at an optimum voltage, the aforementioned sum of the threshold voltages, irrespective of variations in manufacturing tolerances. Accordingly even though the integrated circuit includes a low voltage section it can be operated throughout the normal range of voltages for CMOS circuits as if it contained only "high voltage" devices. <IMAGE>

Title: Improvements in and relating to flow measurement
Inventor: NORTHEDGE RONALD
IPC: G01F1/90
Filed: 1981-07-22
Abstract: Gas dispensing apparatus includes transducers (12,18) for measuring the pressure, temperature and volume flow of gas through a pipe (5) during supply of gas to a customer's tank in a sales transaction. The values of the measured parameters are fed to computing means (22) which on termination of gas supply provides a virtually instantaneous output (24,26) of the standardised volume of gas sold in that transaction and its cost. During filling of the tank the parameters will vary. In particular once the tank is nearly full the volume flow rate will tail off. As the flow falls below a fixed value a valve (9) is closed in cut-off the gas supply automatically as, at this stage, the tank will be sufficiently full.

IPC: H03M1/46
Filed: 1981-09-10
Abstract: An analog output from a local DAC 14, in which a full scale output of an LDAC is always larger than a quantized level of an MDAC is compared (at (15)) with an input analog signal which is sampled and held by S/H circuit (20).

Title: Continuous speech recognizer
IPC: G10L15/10
Filed: 1982-03-24
Abstract: This speech recognizer concatenates a string of reference isolated-words for comparison with the unknown string of connected-words. The invention includes a level-building (LB) algorithm, "level" implying a location in a sequence of words. A constrained endpoint dynamic-time-warp algorithm, in which the slope of the warping function is restricted between 1/2 and 2, is used to find the best alignment between an unknown continuous-word test pattern, and a concatenated sequence of L reference patterns. Properties of the LB algorithm include: modification of the references; back-track decision logic; heuristic selection of multiple candidates, and syntax constraints. As a result, the processing required is less than two-level dynamic-program-matching and sampling algorithms.

Title: Method and apparatus for controlling a pneumatic feed system
Inventor: HEEP DIETER
IPC: B65G53/66
Filed: 1982-08-24
Abstract: A method and apparatus for dosing particulate bulk material to a continuous gas stream for feeding through a closed conveyor (3) to a burner (1) is described. The pressure values of the gas stream are measured at at least two spaced sensor points (3a, 3b) along the conveyor. The value (P2) obtained at the sensor (3b) downstream is modified to obtain a corrected value (P2') proportionally to the counter- pressure closest to the burner (1). This corrected value P(2') is then subtracted from the value (P1) obtained at the upstream sensor (3a). The resultant ( DELTA p') is indicative of the actual pressure differential across the sensed sector of the conveyor (3), corrected for spurious false readings. This resultant actual pressure differential is then compared with a predetermined desired pressure differential for the system, which is a relationship of the desired counter-pressure and the desired load. The result ( DELTA p) of the comparison is then employed as the control signal for regulation of the bulk material feed device. <IMAGE>

Filed: 1982-09-14
Abstract: In a method of sensing fluid flow, a bluff body of elastic material is distorted when vortices are shed, a beam of radiation is modulated by the distortions, and the frequency of modulation is determined. The bluff body may be a hollow body through which a beam of optical radiation is passed; either the beam is reflected by the body wall, distortions causing a change in optical path length which is sensed by the formation of interference fringes, or the beam is passed through a diffracting aperture whose position is altered by the distortions, and the change in position is sensed. Alternatively ultrasound may be used to sense the distortions of the bluff body. <IMAGE>
