Title: Method and apparatus for maintaining and retrieving live data in a posted write cache in case of power failure
Inventor: SCHULTZ STEPHEN M
IPC: G06F11/14
Filed: 1993-06-04
Abstract: ABSTRACT              METHOD AND APPARATUS FOR MAINTAINING AND RETRIEVING LIVE DATA IN A POSTED WRITE       CACHE IN CASE OF POWER FAILURE      A host computer including a posted write cache for a disk drive system where the posted write cache includes battery backup to protect against potential loss of data in case of a power failure, and also including means for performing a method for determining if live data is present in the posted write cache upon power-up.  The posted write cache is further mirrored and parity-checked to assure data validity. Performance increase is achieved since during normal operation data is written to the much faster cache and a completion indication is returned, and the data is flushed to the slower disk drive system at a more opportune time.  Batteries provide power to the posted write cache in the event of a power failure.  Upon subsequent power-up, a cache signature previously written in the posted write cache indicates that live data still resides in the posted write cache.  If the cache signature is not present and the batteries are not fully discharged, a normal power up condition exists.  If the cache signature is not present and the batteries are fully discharged, then the user is warned of possible data loss.  A configuration identification code assures a proper correspondence between the posted write cache board and the disk drive system.  A mirror test executed to verify data validity.  Temporary and permanent error conditions are monitored so that posted write operations are only enabled when error-free operation is assured.

Title: Rocker-Type Support Assembly
Inventor: STANLEY RONALD F
IPC: H01H23/14
Filed: 1993-08-05
Abstract: A support assembly for supporting two poppel-type actuation switches at a housing, such as a radiotelephone handset housing. The actuation switches are positioned beneath a support body of the support assembly and maintained in a desired orientation relative to such support body by pawl arms which extend beneath the support body. Post members extend beneath the support body to abut against membranes of the respective actuation switches. The support body is affixed to the housing by way of retaining arms positioned to extend beneath the support body midway along the length thereof while permitting limited pivotal movement about rocker arms positioned at sides of the support body responsive to twisting moments applied to the support body. The twisting momenta applied to the support body are transmitted to the poppel-type switches by way of the post members form the actuation forces to actuate the poppel-type switches supported thereat.

Title: Piezoelectric sensors
Inventor: CHATIGNY JOHN V
IPC: G08G1/02
Filed: 1993-10-25
Abstract: ABSTRACT A  traffic sensor includes piezoelectric sensors having different polarities in different lanes of the roadway so that traffic data for different lanes of a roadway can be detected from the polarity of the received signal(s).  The piezoelectric sensors may be formed by splicing oppositely polarized piezoelectric cables or films, by changing the applied electric field during manufacture so that adjacent portions of a piezoelectric cable or film have different polarities, or by applying an electric field of a reversed polarity to respective longitudinal sections of a piezoelectric film.  Traffic data from up to eight different lanes of traffic can be detected using only two piezoelectric sensors by providing unique combinations of output polarities for deflections of the piezoelectric sensors in the different lanes.  In order to simplify installation, such piezoelectric sensors may be disposed in parallel within the same housing or concentrically within the same cable.

Patent CA-2110752-A1 (CA)
Title: Process and apparatus for coloring glass
Inventor: ARGENT RONALD D
IPC: C03B5/26
Filed: 1993-12-06
Abstract: The present invention relates generally to the manufacture of glass and, more particularly, to the high volume production of glass containers wherein both colored glass and clear glass containers may be produced simultaneously.           Heretofore, it has been common to either dedicate an entire glass melting furnace to the production of colored glass or to treat clear glass produced by a melting furnace by adding a color concentrate upstream of the glass forming machine in a forehearth region. Such known forehearth coloring technology has several shortcomings, the more notable being the limitation on glass throughput; the high raw material cost of color concentrates; as well as the high maintenance costs and associated downtime of the mechanical color stirrers. In addition, certain color additions requiring longer dwell times or higher melting temperatures, such as that required for producing amber colored glass, for example, cannot be produced by the forehearth coloring technique.              In prior attempts to increase throughput and production flexibility of colored glass, it has been proposed to utilize a so-called "color cell". The prior color cell employed a vertical flow-through refractory structure which diverted clear glass flow from a melting furnace. Color concentrates were added along with colored cullet and melted in an electrically heated zone within the color cell.

Title: Engine torque management during coast downshifting of an automatic shifttransmission
Inventor: MOTAMEDI NADER
IPC: B60W30/18
Filed: 1994-03-18
Abstract: An improved powertrain control which recognizes the occurrence of positive engine torque caused by accelerator walk-in by the operator during coast-sync-coast downshift, and effectively prevents or arrests speed flare via engine torque management controls.  The engine spark timing is normally not responsive to coast-sync-coast downshift conditions, however, when the occurrence of accelerator walk-in results in excessive positive engine torque likely to cause, or actually causing, engine speed flare is detected, spark retard is controlled to a predetermined value, thereby controlling the transmission input torque and allowing smooth application of the on-coming element for completion of the shift.

Title: Method for Obtained High-Quality Protein Products from Whey
Inventor: JENSEN JOHN
IPC: A23J1/20
Filed: 1993-04-29
Abstract: High quality protein products are obtained from whey by subjecting whey to cross flow filtration in microfilter. The whey and retentate are brought to circulate in a circulation path on one side of the membrane area of the microfilter, while whey which has passed the membrane area (permeate) is circulating in a second path on the other side of the membrane area in such a way that the pressure drop over the whole membrane area is kept constant and below 0.8 bar. At that there is obtained a fractionation of milk serum protein such that denatured milk serum protein and fat are retained in the retentate and undenatured milk serum protein passes the membrane into the permeate. After an end treatment there is obtained a whey protein product which is rich in .alpha.-lactalbumin and .beta.-lactoglobulin and has a low fat content.

Inventor: MIYASHITA KOTARO
IPC: F02P5/15
Filed: 1994-12-28
Abstract: An ignition timing control system for an internal combustion engine that estimates the octane number of the fuel being used based on the state of engine combustion knocking and controls the ignition timing to a value not exceeding the knocking limit.  The basic ignition timing is set along the knocking limit of fuel having least octane number and the maximum advance amount is set between the knocking limit and the second knocking limit of fuel having maximum octane number.  Octane number is estimated from the occurrence of knocking. On the other hand, upper limit of the estimated octane number is set based on the MBT of the engine such that the estimated octane number is limited with the upper limit.  Advance rate is determined based on the estimated octane number and is multiplied to the  maximum advance amount to determine an ignition timing correction amount.  The ignition timing is finally determined from the basic ignition timing and the ignition timing correction amount.  A learning control is conducted for the octane number estimated and the estimated octane number is limited within the learned value.
