Abstract: A B S T R A C T - CANADA      A modular harness in which a series of conductors are terminated at opposite ends by identical connectors which are each adapted for connection alternatively to a printed circuit or tabs.  The connectors may comprise a housing base having a longitudinally extending slot in a contact face communicating with two rows of longitud-inally staggered terminal receiving compartments.  The terminals preferably have contact portions with opposed spring arms to grip a tab between them, one arm being bent away from the other arm intermediate its ends to provide a contact surface for a printed circuit at the bend.  The other arm may constitute a back-up spring during contact by the one arm with a printed circuit.

Abstract: ABSTRACT OF THE DISCLOSURE    A concrete slab or panel poured in its horizontal position is fitted with anchor inserts embedded in the concrete that receive releasable pickup units or devices for connecton of the panel to a hoist.  Each insert has a tubular member of a relatively short length to which a hollow plastic mold is attached that extends into the panel.  The mold for the most part remains in the panel and forms a cavity into which part of the pickup device extends.  The pickup device has a trunnion plate that is placed across the insert opening in the panel.          A housing extends through a hole in the trunnion plate into the insert and defines an internal cavity disposed inwardly of the insert.  A bore communicates an end of the housing outside the panel with the housing cavity.  An axially movable actuator rod or plunger is disposed in the bore and includes a head disposed in the cavity and formed of contiguous cylindrical and conical portions.   A plurality of lugs are movably mounted in housing cutouts that extend radially outward of the cavity and such lugs have sides facing the plunger head which are, respectively, parallel to the cylindrical and the conical portions of the plunger head for cooperation therewith so that the lugs are moved radially outward of the housing by the cooperating conical portion of the head and the angularly inclined lug sides.  The lugs are locked in their extended position by the interengagement of the cylindrical head portion and corresponding straight lug sides.  Pawls cooperate with the lugs and the plunger to retract the former in response to a pawl retracting motion of the plunger.

Title: Torsional protective device for power system stabilizer
Inventor: WRIGHT GEORGE F
IPC: H02P9/00
Filed: 1977-12-22
Granted: 1981-05-05
Abstract: ABSTRACT OF THE DISCLOSURE           Power system stabilizers are used in the excitation systems of large shaft driven synchronous dynamoelectric machines for the purpose of enhancing the dynamic stability of power generating systems.  Such stabilizers using speed, power or frequency as an input signal when applied with high initial response excitation systems are effective in damping low-frequency local or inter-tie mode oscillations which may occur in the system. The power system stabilizer may adversely affect torsional damping at higher frequencies.  The adverse effects of a power system stabilizer at shaft torsional frequencies are obviated by providing a torsional oscillation protection device comprising a composite band-reject filter of the present invention which attenuates the power system stabilizer output at the shaft natural torsional frequencies without introducing an excessive phase lag at the local or inter-tie mode frequencies.

Abstract: DISPLAY RANGE MARKER Abstract of the Disclosure A variable range marker device for use with a PPI radar with digitized video displayed in non-real time.  The position of the range marker is initially operator determined by rotation of a knob mechanically linked to an optically encoded disc. Optical sensors produce a digital output indicative of the disc rotation angle and range mark position as a distance from the center of the radar display screen.  A counter is preset with the digital output at the start of each sweep and decremented once each range cell until a count of zero is reached at which time an unblanking pulse is produced.  A numeric display of range is produced by dividing the number of range cells to the range mark by the range setting, scaling according to chosen units of measure, and displaying the result with a LED display, the computations being performed by a processor controlled by a permanently programmed memory.  The range mark stays on target as the range scale is changed.  The amount of movement of the range mark for a given amount of control rotation is independent of range scale.

Abstract: ABSTRACT OF THE DISCLOSURE:             A process for thermally decomposing salts which contain mainly iron sulfate, in a fluidized bed circulating in a vertical shaft, wherein a major part of the resulting metal oxide is dis-charged together with the gas from a top part of the shaft and is separated from the gas in a recycling cyclone and is recycled at least in part to the fluidized bed, the exhaust gas from the flui-dized bed is contacted with feed salt containing mainly iron sul-fate, the fluidized state is maintained by oxygen-containing flui-dizing gas, which optionally has been preheated, and by oxygen-containing secondary gas, which optionally has been preheated and which has been fed above the inlet for the fluidizing gas, and fuel is fed into a zone between the inlets for the fluidizing gas and secondary gas.  The process of the invention is characterized in that the salt which contains at least one mole of water of crystal-lization and mainly contains iron sulfate is contacted in a single suspension-type exchanger with exhaust gases formed by reaction of the oxygen-containing gases in the fluidized bed, the fluidizing gas and at least a partial stream of the secondary gas stream are heated by an indirect heat exchange in a fuel-heated heat exchanger, and the quantity of oxygen introduced  via the fluidizing gas and the secondary gas, is controlled in dependence on the quantity of fuel in order to receive an exhaust gas from the suspension-type exchanger with a free oxygen content of 1-6% by volume and a tem-perature of 300-450°C.  The process has proved to be satisfactory for the decomposition of salts which contain iron sulfate and es-pecially when such salts contain also adherent sulfurin acid.
