Title: Process and apparatus for automating a vacuum degassing stage of aluminium alloys
Inventor: MERRIEN PIERRE L
IPC: C22B21/06
Filed: 1980-11-19
Granted: 1987-08-27
Abstract: Apparatus and process for automating a vacuum degasification cycle for metal alloys, particularly aluminum alloys. The process comprises adjusting the degasification speed to sequentially correspond to a plurality of sets of degasification speed parameters. Each set of degasification speed parameters corresponds to a predetermined desired degasification speed. The degasification speed may be adjusted by adjusting the vacuum surrounding the alloy. The degasification speed is triggered to change from corresponding to one set of parameters to another set of parameters by the sensing of a series of predetermined partial pressures of gas in the alloy. The apparatus includes an inlet-outlet assembly for transforming given indications into a numerical form for the parameters of the degasification cycle and a calculator assembly adapted to transform the speed of degasification into variations of theoretical partial pressure and to regulate the pressure in the enclosure of the furnace to obtain an identical variation to that required based upon the indications of the standard curve placed in the assembly memories. Several furnaces may be regulated. The temperature of the metal may be regulated at a level equivalent to that required before casting. The apparatus can include a microprocessor.

Title: Chair shells
Inventor: WATKIN BERNARD CURTIS
IPC: A47C3/12
Filed: 1981-01-20
Granted: 1984-06-20
Abstract: A chair shell of resilient material such as polypropylene comprises a back support 12 and a seat portion 14. The natural deformability of the back support 12 is modified by slits 22, 24 and holes 32, 34, 36 so that under pressure from the back of a sitter resting against the back support the support is resiliently deformed into a shape which, in vertical section, includes a convex curve positioned properly to support the sitter's spine in the lumbo-sacral region and which is horizontal in convex section. The deformability of seat 14 is modified by slits 42, 44 and holes 42,46,48,50,54 to provide softer rear and front zones 44 and 52 to reduce the pressure on the ischial tuberosities and lower thighs of the sitter. The chair shell provides comfortable and orthopaedically desirable support whilst avoiding the need for thick upholstery. The undeformed state of the chair shell may be designed to allow the chairs to be easily stacked.

Title: Circuit arrangement for the generation of control magnitudes from the loop current
Inventor: EBERHARDT KURT DIPL ING
IPC: H04M1/58
Filed: 1982-04-15
Granted: 1985-04-25
Abstract: To control the earphone and microphone amplifiers as well as the balancing network of a subscriber's telephone terminal which is fed, through a subscriber line in communication systems, to the effect that the attenuations in subscriber lines of unequal lengths do not affect the transmission characteristics between the exchange and the subscriber, a circuit arrangement is provided for producing the necessary control function, which is simple, integratable and has minimum tolerances. Above a predetermined threshold value, a voltage proportional to the line current variations controls the emitter-to-base junction of two grounded-base transistors at the collectors of which the control current is available. The control currents produce their effect on the negative feedback of the microphone and the earphone amplifiers. An increasing line current causes the cotrol current to decrease, thereby effecting a stronger feedback and a reduced amplification. Further, the voltage proportional to the line current variations and available at the emitter resistor of another transistor, controls the balancing impedance through a current mirror, to attenuate the sidetone independently of the length of the subscriber line.

Patent DE-3266336-D1 (DE)
Title: Method and circuit arrangement for measuring a magnetic field, especially the terrestrial magnetic field
Inventor: KRATZER WOLFGANG DIPL ING
IPC: G01R33/02
Filed: 1982-05-19
Granted: 1985-10-24
Abstract: In order to measure a magnetic field, an exciting current rising in small increments is applied to a measuring probe so that the coil of the probe traverses the entire range from the negative saturation up to the positive saturation. At the secondary side, respective voltage pulses which decay according to an e-function are measured at the coil. The time constant of the voltage pulses corresponds to the respective coil inductance. Since the coil inductance is shifted relative to the zero point of the exciting current due to an external magnitude field, more voltage pulses with a high time constant are produced on one side of the zero point than on the other side. By means of digital counting of all voltage pulses whose time constant exceeds a minimum value both given a negative exciting voltage as well as given a positive exciting voltage, one obtains two measured values whose difference directly produces a measured value for a strength of the external magnetic field.

Title: Row sensing apparatus for a crop harvester
Inventor: WILLIAMS TERRY ARDEN
IPC: A01D45/02
Filed: 1984-08-31
Granted: 1988-03-03
Abstract: A forage harvester (11), pulled via its tongue (16) by a tractor, has dividers (19, 21) between which a crop row (18) is received, and each divider (19, 21) has a row sensing unit (41, 43) bolted to it. The crop row (18) passes between a pair of arms (47, 48) of the unit. An arm (47, 48) is deflected, when the machine is misaligned with the row (18), the arm (47, 48) having an upright pivot shaft (79). The arm (47, 48) carries an actuator plate (95) which closes a switch (145) to trigger a guidance control circuit (45) to steer the harvester by way of a piston and cylinder (33) moving the tongue (16) to return the harvester (11) to alignment with the crop row (18). To enable the harvester (11) to be reversed without the crop row (18) fouling the crop-engaging arms (47, 48) each arm is formed with a trailing portion which curves rearwardly through an angle greater than a right angle toward the divider (19, 21) and then terminates below the divider (19, 21) so that crop can pass smoothly over the arm not only when the harvester is travelling forward, but also when it is reversed.

IPC: A01C7/00
Filed: 1985-09-09
Granted: 1991-03-28
Abstract: A linear array of light emitting diodes (CR1-CR7) direct a diffuse beam of radiation across the path of seeds dropping down a seed chute and onto two detectors (46,48) connected in parallel, so that every seed produces a substantially equal area pulse in the output signal from the photo detectors. The signal is amplified (50) and applied to an analog to digital converter (52) producing digital samples at a high rate for processing by a microprocessor (54). The sensor value is subtracted from an offset value corresponding to the sensor signal when no seed is present and the difference signal is repeatedly added to an area signal. The offset value is adjusted from time to time to prevent the difference signal staying persistently negative or persistently positive. Whenever the area signal reaches a threshold value the passage of a seed is indicated and the area signal is decremented by an estimated area value corresponding to one seed. This estimated area value is adjusted from time to time so as to avoid long term drift in the area value, thereby maintaining the estimated area value accurately representative.
