Title: Method of and apparatus for predicting floating point
IPC: G06F7/76
Filed: 1989-02-24
Abstract: In data processing systems operable to perform floating point computations there is provided a method, and apparatus implementing that method, for predicting, in advance of the floating point computation, whether or not the computation will produce a floating point exception (e.g., overflow, underflow, etc.). The prediction method includes the steps of combining the exponent fields of the operands of the computation in a manner dictated by the type of operation (i.e., add, subtract, multiply, etc.), and comparing that combination, together with an indication of the computation to be performed (e.g., add, subtract, multiply, or divide), to obtain an indication of the possibility of the computation ending in a floating point exception. If an exception is predicted, the indication can be used to halt other data processing operations until completuion of the computation so that, in the event the computation actually results in a floating point exception, the handling of the exception can be accomplished with a minimum of effort.

IPC: C08K5/5425
Filed: 1989-04-13
Abstract: The method of this invention produces a high 
strength, one-part fluorosilicone sealant which is stable in 
the absence of moisture and contains an in situ treated 
reinforcing silica filler. The fluorosilicone sealant is 
produced by a process which in situ treats the reinforcing 
filler with a di(trifluoropropyl)tetramethyldisilazane in the 
presence of a portion of the fluorosilicone polymer. The 
remainder of the polymer is then added and the reinforced 
polymer is admixed with a moisture activated curing system to 
give a sealant which cures upon exposure to moisture to give 
an elastomer. The sealant is easily extrudable from a 
storage container. The cured elastomer has improved tensile 
strength, tear strength and elongation values. The cured 
elastomer, being a fluorosilicone, is resistant to non-polar 
organic hydrocarbon fluids such as aircraft jet engine fuels 
and gasoline.
Patent EP-0369703-A3 (EP)
IPC: H04B1/709
Filed: 1989-11-13
Abstract: A spread spectrum communications system includes an encoder 
for differentially encoding a spread spectrum spreading 
code sequence in accordance with an input data signal. 
Each chip of the spreading code sequence is inverted, or 
not inverted, relative to the polarity of a corresponding 
chip of the spreading code sequence a fixed time delay 
previously, depending on whether the input data is a logic 
one or zero, respectively. At the receiver, the data is 
recovered in a differential data decoder wherein the 
presently received chip of the spread spectrum signal and a 
previously received chip of spread spectrum signal, a fixed 
time delay previously, are compared one chip at a time. 
Since it is the spreading code sequence that is 
differentially encoded and differentially decoded, there is 
no need for a synchronized code sequence generator at the 
receiver, and data synchronization is achieved after one 
cycle time of the received spread spectrum spreading code 
sequence has elapsed.

Title: Electrical machine, rotor therefor, and method of assembly
IPC: H02K3/487
Filed: 1991-07-25
Abstract: Disclosed is a rotor body for an electric machine having slots for windings and slot keys with wedges for retaining the windings in the slots. The slot keys contain elongated spring strips underlying an amortisseur, in turn, underlying the wedges in the slot keys. The spring strips bias the amortisseur and wedges radially outwardly. Thus, the wedges lie in sufficient, low-resistance, efficient electrical contact with the rotor body at start-up and during low rotor speeds to prevent arcing and localized heating along the interfaces of the rotor parts otherwise resultant from induced surface currents at start-up and low rotor speeds. At the rotor ends, the spring strips bias the amortisseur ends radially outwardly into efficient electrical contact with retaining rings at opposite ends of the rotor body. A tool is also provided having a main arm, a pair of pivotally mounted dogs for engagement in the slot key and straddling the external surface of the slot key, respectively, whereby the tool may be fixed in axial position along the slot key by pressure on the main arm. A second pivotal arm carries a wedge-engaging head whereby the lever is fixed in the slot and the second arm drives the wedge longitudinally into axial <IMAGE>

Patent EP-0497441-A3 (EP)
Title: Improved microprocessor synchronous timing system
IPC: G06F13/42
Filed: 1992-01-02
Abstract: There is disclosed a timing system for use in a microprocessor for initiating microprocessor outputs onto an input sampling from an external bus in synchronism with a bus timing clock. The timing system is operative in a first mode for internally generating the bus timing clock and in a second mode for being driven from an externally generated bus timing clock. In the first mode, the timing system generates first and second inverse phase timing clocks responsive to an external clock source and independently generates the internally generated bus timing clock with the rising edges of the bus timing clock coinciding with the rising edges of the first microprocessor timing clock and the falling edges of the second microprocessor timing clock. In the second mode, the timing system generates the first and second microprocessor timing clocks in response to the externally generated bus timing clock. In both modes, the timing system initiates an output onto the bus upon the common assertion of the first microprocessor timing clock and the bus timing clock and initiates sampling of an input from the external bus upon the inverse assertion of the second microprocessor timing clock and the bus timing clock.

Title: Cemented carbide with binder phase enriched surface zone.
Inventor: GUSTAFSON PER
IPC: C22C1/05
Filed: 1993-12-08
Abstract: The present invention relates to a new process for binder phase enrichment. The process combines binder phase enrichment by dissolution of cubic phase with the requirements that cause formation of stratified layers, resulting in a unique structure. The new structure is characterised by, in comparison with the ones previously known, deeper stratified layers and less maximum binder phase enrichment. The possibility of combining dissolution of the cubic phase with formation of stratified layers offers new possibilities to optimize the properties of tungsten carbide based cemented carbides for cutting tools. The new process offers possibilities to combine the two types of gradients. The dissolution of cubic phase moves the zone with maximum amount of stratified binder phase from the surface to a zone close to and below the dissolution front. By controlling the depth of dissolution, the interstitial balance and the cooling rate a cemented carbide with a unique combination of toughness and plastic deformation resistance can be achieved. <IMAGE>

Abstract: A dynamic memory comprises a control circuit

decoder and the activation of the sense amplifiers in
accordance with a  RAS  signal externally supplied
thereto and a word line control circuit (11) for
controlling a selected word line to turn the electric
potentials read out from the memory cells connected to
the word line on the bit lines connected to the
respective memory cells back to an inactive level after
the electric potentials are sensed and amplified by the
sense amplifiers corresponding to the respective bit
lines during the time period from the time when the  RAS 
signal is turned to an active level and the time when
it is turned back to the inactive level. A dynamic
memory has gate oxide films are designed to be
subjected to a less electric field strength in order to
minimize the degradation of reliability and the memory
can effectively reduce the fall of the word line
driving stepped-up voltage to eliminate the necessity
of a leak current compensation circuit. Additionally,
the memory reduces the time required to restore the
electric potentials for a data reading operation and
also the cycle time required for a data writing operation.
