Abstract: APPARATUS AND METHOD FOR WORKING ON SUCCESSIVE SEGMENTS OF SHEET MATERIAL                  ABSTRACT OF THE DISCLOSURE         Apparatus for cutting patterns from successive con-tiguous segments of an elongated layup of sheet material has a zoned vacuum table which includes an endless bristle mat conveyor, for shifting a layup along the table to position a segment of the layup in the cutting zone of the table and for holding the layup segment in the cutting zone, and a carriage assembly, which moves a cutting mechanism relative to the table and in cutting engage-ment with the segment to cut patterns from the segment in re-sponse to signals from a programmable controller.  A rotary en-coder mounted on the carriage assembly has a pinion which engages a rack carried by the conveyor to detect movement of the carriage assembly relative to the conveyor when the carriage assembly re-turns to its starting position after completing its cutting cycle A responsive circuit connects the encoder to the conveyor drive motor and energizes the drive motor in response to the relative movement detected by the encoder to cause the conveyor to move the layup in the return direction and through a distance equal to the distance traversed by the carriage assembly in returning to its starting position whereby the next successive segment of the layup is accurately positioned in the cutting zone.  An error sensing circuit detects the magnitude and direction of an error in positioning the layup and alters the data in the controller to nullify the error.  A vacuum device cleans the bristle mat while the conveyor is in motion and also reduces the vacuum holddown force applied to the layup while it is being shifted by the con-veyor.

Abstract: THREE-POINT HITCH DRAFT CONTROL                   Abstract of the Disclosure The draft control consists of a three-point hitch mechanism which automatically raises or lowers the hitched implement so that a predetermined draft load can be maintained.  An increase or decrease draft load on the implement is sensed by an upper hitch arm.  A linkage mechanism transfers this force through a number of links of proper length, such that, the implement is raised with excessive draft load and lowered the implement as the draft load decreases from the excessive level.  The draft load that is to be maintained is determined by the location of the middle link in one of a plurality of holes in the attaching linkage.  Structure is provided to lock out the draft control.

Abstract: ABSTRACT OF THE DISCLOSURE           An electric power generator system includes a switched capacitor controlled induction generator adapted to provide power at a regulated voltage and frequency.  The induction generator system includes an n-phase induction machine having a rotatable input shaft and at least n output lines.  The input shaft is driven at a controlled frequency by a prime mover.  An N-stage,  switched capacitor array provides a controlled reactive current to the output lines of the induction machine.  Each stage of the array includes a capacitor network associated with each of the permutations of pairs of the n output lines.  The capacitor networks for each stage are characterized by substantially the same capacitance.          Each stage further includes an associated switch network associated with each capacitor network for selectively coupling the capacitor network across its associated pair of output lines.          A feedback network is coupled  between the output lines and the capacitor array to adaptively control the switching of the various N-stages in and out of operation.  In grid-connected operation, the feedback network includes a power factor detector for producing a signal representative of the power factor at the output lines of the induction machine.   The feedback network uses this power factor signal to control the switched capacitor array to adaptively vary that net capacitance across the output lines of the induction generator so that the generator presents a unity power factor to the grid.

Title: Fire and explosion detection and suppression
Inventor: FARQUHAR ROBERT L
IPC: G08B17/12
Filed: 1981-07-10
Granted: 1984-07-10
Abstract: ABSTRACT OF THE DISCLOSURE  The invention is for discriminating between the fire or explosion of an ammunition round and the fire or explosion which may then take place in the object struck by the round, and for initiating suppression of the latter fire or explosion only.   Short wavelength radiation detectors feed a ratio detector which produces a logical output dependent on whether or not the color temperature of an event being monitored is above or below a fixed value.  If the event is an exploding round then this will take the color temperature above this fixed value.   A threshold unit and a rate of rise unit produce logical outputs dependent on whether the magnitude and rate of rise of the output of one of these two detectors are above or below fixed values.  An infra-red detector detects radiation at a wavelength characteristic of a fire in the object;  its output rises relatively slowly.  If this detector detects a fire at this wavelength, it enables an AND gate but the gate does not initiate fire suppression if the ratio unit indicates that the color temperature is above the fixed value, because this signifies that the event is an exploding round.  Fire suppression cannot take place until after the color temperature has fallen (and after a fixed delay produced by a monostable).  The threshold unit and the rate of rise unit provide protection against incorrect initiation of fire suppression in conditions when the exploding round does not produce a color temperature clearly in excess of the fixed value.

Abstract: ABSTRACT OF THE DISCLOSURE        A method for operating a frequency converter of the type having an auxiliary commutating device for commutation at speeds which are lower than a machine-related minimum speed of operation.  In a first speed range which begins at speed zero, the thyristors of a three-phase bridge of the inverter are commutated cyclically, as customary, six times per revolution of the machine.  In a second speed range which is adjacent to the first speed range and below the machine-related minimum speed of operation, only every second commutation is executed.  In embodiments of the invention wherein there is provided a third speed range which is adjacent to the second speed range and extending up to the machine-related minimum speed, only every third commutation is executed.  In this manner, an auxiliary commutating device having a predetermined frequency limit can be utilized at speeds corresponding to two or three times the speed at which such an auxiliary commutating device could be used in prior art systems.  Only slight drops in mean torque are experienced with the inventive method.

Abstract: PREPARATION OF BILIQUID FOAM COMPOSITIONS            Abstract of the Disclosure A biliquid foam composition is prepared by agitating a hydrogen bonded liquid containing a soluble surfactant to produce a gas foam and intermittently adding to the gas foam a non-polar liquid which is immiscible with the hydrogen bonded liquid, the sur-factant-containing hydrogen bonded liquid and non-polar liquid being selected to provide a spreading coefficient equal to or greater than zero.  The resulting mixture is agitated after each addition so as to cause the non-polar liquid to initially spread on the foam surfaces and thereafter form non-coalescing globules of non-polar liquid dispersed in a continuous phase of the hydrogen bonded liquid and each encapsulated in a double surfaced surfactant-stabilized film of the hydrogen bond-ed liquid containing the soluble surfactant.  The quantity of non-polar liquid added at each addition is such that the hydrogen bonded liquid remains the envi-ronment of any encapsulated globules of non-polar liquid formed, the total phase volume ratio (PVR) of the non-polar liquid to the hydrogen bonded liquid being up to about 50.  The biliquid foams prepared in accordance with the invention have several noteworthy applications.          For example, biliquid foams made of hydrocarbons and water are exceptionally good cleaning agents since they comprise both a finely dispersed hydrocarbon which can remove greases and water combined with detergent which can remove water soluble soils.

Abstract: ABSTRACT OF THE DISCLOSURE      A helical mattress or furniture spring 1 has two opposite end windings 2a, 2b lying in parallel planes.  Each end winding contains only one bent-out area 5a, 5b having a wire segment 6a, 6b running in a straight line.  The side of each end winding lying opposite this straight wire segment has a circular zone 7a, 7b.  The two bent-out areas of each spring lie diametrically opposite each other.  A spring coil assembly made of such helical springs has the same operational qualities as "offset spring coils" in which there are two bent-out areas in each end winding, but it is much easier and less expensive to produce on automatic assembly equipment.
