Title: Cache address generation
Inventor: JEREMIAH THOMAS LEO
IPC: G06F12/10
Filed: 1998-06-11
Granted: 2002-01-29
Abstract: A cache system provides for accessing set associative caches with no increase in critical path delay, for reducing the latency penalty for cache accesses, for reducing snoop busy time, and for responding to MRU misses and cache misses. The cache array is accessed by multiplexing two most-recently-used (MRU) arrays which are addressed and accessed substantially in parallel with effective address generation, the outputs of which MRU arrays are generated, one by assuming a carryin of zero, and the other by assuming a carryin of one to the least significant bit of the portion of the effective addressed used to access the MRU arrays. The hit rate in the MRU array is improved by hashing within an adder the adder's input operands with predetermined additional operand bits.

IPC: C08B37/16
Filed: 1998-06-29
Granted: 2002-06-25
Abstract: Sulfoalkyl ether cyclodextrins are produced by a process of treating an unsubstituted cyclodextrin starting material with an alkyl sultone in the presence of a base. The base is added in a stepwise, pH controlled manner so that substantially the entire initial charge of cyclodextrin starting material is at least partially reacted. Additional base is then added to complete the reaction, and residual alkyl sultone is destroyed. The product advantageously contains low levels of both residual cyclodextrin and residual alkyl sultone.

Granted: 2008-08-05
Abstract: To accommodate for a release of uncleared spectrum in a wideband communication system (10) while improving isolation in a receiver (FIG. 4) between wideband carriers, a common intermediate frequency converter down-converts differing but relatively high frequency carriers, incident to the receiver, to corresponding differing but relatively low frequency carriers. Receiver chains (174-176) response to the plurality of relatively low frequency carriers each have a filter (140-144) arranged to isolate selected ones of the relatively low frequency carriers. In a radio frequency communication system having three or more frequency sequential carriers, the receiver chains (174-176) may include branches that have filters that further isolate carriers within the receiver by applying non-sequential carriers to the branches in each receiver chain.
Patent CA-2261608-C (CA)
Inventor: SCHULE JOSEF
IPC: E04G17/04
Filed: 1997-07-11
Granted: 2006-05-23
Abstract: The invention concerns a clamp (1) which is used for connecting control pane ls disposed adjacent one another in a plane and to that end engages on edge web pieces (2) or edge profiles of these control panels. These edge web pieces ( 2) lie immediately adjacent one another or can have an intermediate part therebetween. For adaptation to spacings which consequently vary or to different dimensions of the edge web pieces (2) or edge profiles, a first pivotable clamping jaw (4) is continuously displaceable in its direction of longitudinal extension relative to a fixed clamping jaw (5), on a carrier comprising the two clamping jaws (4 and 5). To that end, the first clamping jaw is pivotably mounted on a slide (10) which can in turn be fixed in any position by clamping on the carrier (6), in particular by tilting or pivot movements in opposite senses. In this way the spacings between the clamping jaws (4 and 5) can be continuously adjusted without measures having to be taken on the carrier (6) itself in order to hold the pivot pin (9) of the pivotable clamping jaw (4), which would weaken the carrier (6).

Title: Reducing nox emissions from an engine by temperature-controlled urea injection
Inventor: PETER-HOBLYN JEREMY D
IPC: B01D53/90
Filed: 1998-03-31
Granted: 2007-02-13
Abstract: A safe, reliable SCR system for reducing NO x emissions from a lean-burn internal combustion engine utilizes urea in aqueous solution. Overheating and hydrolysis of the solution are prevented by maintaining the temperature of the urea solution sufficiently low that it is not permitted sufficient time at elevated temperature to hydrolyz e the urea to such an extent that solids precipitate. In a preferred embodiment, an injector system similar to those used for fuel injection provides a constant feed to injectors (32) and a return line (33). The feed and injection can be controlled to provide sufficient urea for NO x reduction and sufficient cooling capacity for the feed and injection system to avoid hydrolysis and deposits of hydrolysis products.

Abstract: The output voltage of a D.C. motor used to raise and lower a railroad crossing gate is monitored to detect when the D.C. motor begins to generate power, indicating that the motor is being driven by a rising gate arm. If the motor generates power above a adjustable predetermined value, the gate arm mechanism is considered to be operating too fast whereupon an impedance is shunted across the motor's armature thereby applying a load to the generating motor. The electrical load causes the motor to act as a dynamic brake slowing the gate arm mechanism operation and reducing the likelihood that the mechanical components of the crossing gate arm mechanism will be damaged.
