Title: Method and apparatus for driving a cutting blade in a self-propelled saw
Inventor: TROTTIER RICK
IPC: B28D1/12
Filed: 1994-11-10
Abstract: Conventional self propelled saw cutting machines utilize air cooled transversely mounted, internal combustion engines. The engine drives a rotatable circular saw blade through a series of pulleys or chain drives. Since the saw is driven at substantially ninety degrees to the engine output shaft this places a considerable side loading on the crankshaft and bearings. In addition the air intake of the engine is in line with and rearward of the saw blade and thus contaminants from the saw cut are drawn into the engine. The method and apparatus of the present inven-tion eliminates both problems by mounting the engine "in-line" with the vehicle frame rather than transversely. This significantly reduces the likelihood of saw cut contaminants entering the engine air intake. A differential assembly is coupled to the output shaft of the engine and, through a pulley system, drives a rotatable axle shaft to which is coupled the saw blade. Mounting the engine "in-line" with the frame opens the possibility of using diesel engines to power the vehicle without increasing the vehicle width and with no loss in maneuverability.

IPC: G06F13/00
Filed: 1994-12-14
Abstract: A filter module allows controlling network security by specifying security rules for traffic in the network and accepting or dropping communication packets according to these security rules. A set of security rules are defined in a high level form and are translated into a packet filter code. The packet filter code is loaded into packet filter modules located in strategic points in the network. Each packet transmitted or received at these locations is inspected by performing the instructions in the packet filter code. The result of the packet filter code operation decides whether to accept (pass) or reject (drop) the packet, disallowing the communication attempt.

Title: Improvements relating to a tamper evident ring for a container closure
Inventor: KING WITNEY MILNER
IPC: B65D41/34
Filed: 1993-11-15
Abstract: A closure is threadedly securable to a container neck (70). The closure carries a tamper evident ring (80) which includes a collar from which extend a plurality of inwardly inclined resilient tabs (82).  The tabs can flex outwardly relative to each other without stressing substantially the collar to enable the ring to fit easily over a projecting bead (72) on the neck.

When the closure is removed for the first time, the tabs (82) abut the ratchet stops (74) and the bead (72) to release the ring from the closure and to retain the ring securely on the neck. The ring can be of plastics and integrally joined to the closure by severable connections.

Title: Electrode cap with integral tank cover for acid mist collection
Inventor: MURRAY JAMES A
IPC: C25C7/00
Filed: 1993-11-19
Abstract: In a tank confined electrowinning process having circulated electroplating solution containing sulfuric acid, a multi-element cover system (R) is applied below the electrode conductor connections and above the surface of the electrolyte bath (B). This cover is evacuated in the interstices (P) below the cover and above the bath at a rate exceeding the stoichiometric ratio causing any leakage to occur into the volume overlying the bath thereby preventing acid aerosol from escape. The primary cover element constitutes dual hardness extruded, tapered plastic anode caps (30) fastened to opposite sides of the anodes (A) by corrosion resistant fasteners. This anode caps each include an eave member spanning to the cathodes (C). These respective eaves are tapered and extend from a rigid portion of the extrusion fastened at the anode with sufficient span to form a substantially air tight seal with the cathodes immediately after the cathodes are freshly harvested and cleaned. The eaves preferably are sloped to and toward the bath.  These eaves are sufficiently flexible to maintain a conformable seal at the inserted cathodes as well as to yield to allow the copper plated cathodes and their required edge strips to be both withdrawn and inserted.

Title: Fdic method for minimizing measuring failures in a measuring system comprising redundant sensors
Inventor: FISCHER HARALD
IPC: G01D3/08
Filed: 1995-12-18
Abstract: The method according to the invention for mini-mizing measured quantities which are determined  from sensors affected by measuring failures and are detected by a plurality of redundant sensors connected to form a measuring system, by detecting and isolating the sensors affected by failures, provides that the sensor values measured by all  the  sensors  are mapped by a  linear transformation into a vector in the parity space (parity vector), the dimension of the parity space being deter-mined by the redundance of the measuring system, which is to say by the number of sensors and the dimension of the quantity to be measured.  The principle of the method consists in that, by projection of the measured parity vector onto all possible subspaces,  it is determined which of the subspaces at each failure level contains the largest proportion of the measured parity vector.  By omitting  the  sensor  combinations  belonging  to  these subspaces, the best sensor combination at each failure level can be determined.     The invention fundamentally differs from known parity methods or maximum likelihood methods in that the geometrical  interpretation  of  the  properties  of  the parity  space  and their  consequent use  for  isolating simultaneously occurring multiple failures are used, the directions in the parity space being determined in an off-line  analysis,  and  the  isolation  results  being provided in a precalculated table. In particular,  the method allows an optimally possible adaptive matching of the detection thresholds to the general noise level of the sensors assumed to be failure-free.

Abstract: Two heat exchangers are hooked up together in order to generate a flow of cold gas.  A deep-frozen liquefied medium is evaporated in the first heat exchanger (1) by means of heat exchange with a heat transfer medium.  The evaporated medium is re-cooled in the second heat exchanger. The deep-frozen liquefied cryogenic medium used for this purpose is likewise evaporated in this process.  The two flows of gas thus generated are conveyed to a mixing site and then combined to form a flow of cold gas.
