Patent SE-8003043-L (SE)
Inventor: WALKER L H
IPC: H02P3/18
Filed: 1980-04-23
Abstract: Apparatus and method for high slip operation of an AC electric motor at substantially zero rotation and substantially zero torque in an AC electric motor drive system is disclosed. The electric motor produces a rotation in response to an outgoing signal, such as a drive current, of variable magnitude and frequency supplied by the drive system. An idle control signal is furnished when the drive system is in a substantially zero rotation and substantially zero torque state, where the frequency of the current is approximately zero. The idle control signal causes substantially simultaneously an adjustment of the magnitude of the current to a predetermined magnitude level and a rapid raising of the frequency of the current to a higher frequency value to produce per-unit slip s=(n1-n)/nb greater than 0.1, where n1 is the synchronous rotation of the stator field of the motor, n is the rotation of the rotor of the motor, and nb is the synchronous speed of the stator field at motor rated rpm. The adjustment in the magnitude and the rapid increase in the frequency of the current causes the motor to produce substantially zero rotation and substantially zero torque because the motor is operating in the high slip region of its torque-rotation curve. The apparatus and method of the present invention allows the motor to accelerate rapidly on command from the substantially zero rotation and substantially zero torque high slip mode.

Abstract: The temperature of the working gas in the heating chamber of each of a number of cylinders is continuously measured. An electronic selection circuit selects the lowest measured temperature as a control parameter by which the speed of a blower in the common air supply is controlled for providing an air flow proportional to blower speed. A pressure-detecting device measures the air flow through a pressure converter provides an electrical signal that normally controls the valves of the respective fuel supplies for the combustion chambers of the cylinders, but a monitoring device for each cylinder compares the measured working gas temperature with a pre-set maximum value so that when the maximum value is exceeded, the fuel supply valve is changed over to control by the output of the monitoring device, to reduce the fuel supply until the maximum temperature is no longer exceeded in that cylinder. For still a higher temperature of the working gas in any cylinder, determined by another sensor, a general shutdown valve reduces the common fuel supply. An auxiliary air supply provides atomizing air for fuel injection.

Abstract: An instrument for developing at a central control station a signal responsive to the value of a process condition occurring at a field measurement station remote from the central control station wherein a resonant device is used as the instrument basic sensor element. The resonant device which is located at the field station may be excited by either a voltage pulse or a continuous wave. In a particular aspect, the output measurement signal of the instrument is solely dependent upon the value of a desired measured variable, which is representative of a process condition, and is independent of other variables. The resonant device is coupled to excitation and detection circuitry located at the central control station and produces in the detection circuitry when excited with a pulse of energy first and second signals, one of which is dependent upon the desired measured variable and a second variable and the other dependent upon at least the second variable. These two signals are then combined according to known mathematical and physical principles to produce an output dependent upon the value of the desired variable.

Abstract: The invention relates to a device comprising a mattress support intended to be placed underneath a mattress or the like, to facilitate the care of bedridden patients. The support consists of a number of sections (1), each comprising a rigid board (4) or the like, extending essentially fully across the width of the support, and underneath each such board at least two inflatable cells (13a, 13b), of which at least one is placed on each side of an imaginary center line (14) along the support (21). The sections are adjoining along their adjacent edges (2), said joint being articulate and/or permitting the disassembly and reassembly of the support, and the inflatable cells on each side of said center line are inflatable independently and optionally, thus providing for a slow rocking of a patient lying on the bed, via the rigid boards and the mattress (23) on top of the support, thereby causing a redistribution of the areas of pressure between the mattress and the patient which in turn counteracts the formation of bed sores and/or provides a certain massaging effect.

Abstract: The drinking valve for pigs is made up of two main parts, a front valve housing 1 and a rear valve housing 2, between which is secured a rubber sleeve 7, the other end portion of which surrounds a drinking nipple 3. When a pig actuates the nipple 3, a pin 4 is raised, allowing water to flow towards the valve housing 1, via two hollow plates (8, 9) provided with a rivetted joint which control the quantity of water, and enter the drinking nipple 3. Since the drinking nipple is sprung, only a small force is required to make water flow out. Accordingly, even pigs which are only a few hours old can use the drinking valve unaided. <IMAGE>
