Abstract: Cette invention se rapporte à un mécanisme à loquet commandable, qui est installé dans le cadre de porte d'une chambre d'hôtel. Un loquet pivotant vient se placer en prise à la fois avec un verrou sollicité par ressort et avec un pêne dormant associés à la porte de la chambre. L'état du pêne dormant est détecté. Un clavier alphanumérique, situé à l'extérieur de la chambre, permet d'introduire les codes d'accès. Lorsqu'un code d'hôte autorisé est introduit, une unité de commande gérée par microprocesseur déverrouille le mécanisme à loquet, quelque soit l'état du pêne. Le code d'hôte peut être modifié par l'hôte lui-même, si celui-ci le désire. Lorsqu'un nettoyeur introduit un code d'accès universel, l'unité de commande déverrouille le mécanisme à loquet uniquement si le pêne est déverrouillé. Des codes prioritaires spéciaux sont prévus pour déverrouiller le mécanisme à loquet, même si le pêne est verrouillé, ce qui permet au personnel de sécurité d'intervenir en cas d'urgence. Un interrupteur d'alarme situé dans la chambre permet de produire un signal d'alarme et, simultanément, de libérer le mécanisme à loquet, pour permettre au personnel de sécurité et aux allants et venants d'intervenir. Des mécanismes à loquet et des unités de commande similaires sont associés à chaque chambre de l'hôtel et sont reliés à des stations centrales, pour que les signaux d'alarme et les informations diverses puissent être transmis aux stations centrales de l'hôtel.

Title: Process and device for making use of plastic-coated or sheathed wiring and waste wire for the separate recovery of metal and pure recyclable plastic
Inventor: DRZEVITZKY BERND
IPC: B03B5/34
Filed: 1995-02-08
Abstract: The invention relates to a method for the recycling of plastic-coated cable residues, which comprise a metal core and a plastic jacket, wherein the metal parts are separated from the jacket and are separately recovered. The cable residues are communited and the chopped material is softened in a swelling container (10) with a swelling agent for the plastic. Subsequent to softening, the mass flow is fed with the swelling agent to a roller cone mill (13). The roller cone mill (13) flexes the chopped material and destroys the macrostructure of the cable pieces mechanically. The metal particles are separated from the jackets by way of stirring in a stirrer (14), and the multi-phase mixture is transported to a metal sedimentor (16). The heavier metal particles sink down in the metal sedimentor (16) based on gravity and separate themselves from the lighter plastic particles. The transport speed of the transport flow in the metal sedimentor (16) is selected such that the metal particles corresponding to their size-dependent different sinking speeds sink up to the outlet out of the metal sedimentor (16). A countercurrent of swelling agent is entered into the transport flow, where the countercurrent discharges the lighter plastic particles from the transport flow. Thereupon, the countercurrent with the plastic particles is led out of the metal sedimentor (12) as a partial flow and is led into a plastic sedimentor (38) for the sedimented depositing of the plastic particles. The method is performed sealed against gas and the swelling agent is cyclically recovered.

Title: Method and apparatus for decreasing modem retraining due to blank and burst signalling in analog cellular systems
Inventor: WALKER MICHAEL RODNEY
IPC: H04W36/02
Filed: 1995-03-09
Abstract: Modem throughput across a cellular mobile telephone network is increased by controlling the response of the modem to blank and burst orders. In the case of a power control order, the modem may be made aware of the fact that the channel has not changed. Significant performance gain in terms of channel throughput can then be achieved by avoiding a lengthy retraining procedure. The modem operation may be suspended during the blank and burst order and enabled after the blank and burst order, avoiding an unnecessary retrain procedure during the blanking period. In the case of a handoff, the modem may be directed to immediately perform a retrain procedure rather than wait for the long blanking period to be detected by the modem or the link access procedure.

Patent CA-2203124-A1 (CA)
Title: Handling of exceptions in speculative instructions
Inventor: EBCIOGLU KEMAL
IPC: G06F9/38
Filed: 1996-01-09
Abstract: CPU overhead is minimized through tracking speculative exceptions (202) for later processing during exception resolution (204) including pointing to the addresses of these speculative instructions, and resolving (204) these exceptions by correcting (206) what caused the exception and re-executing (208) the instructions which are known to be in a taken path. Tracking speculative exceptions has two components which use an exception bit which is set in response to an exception condition (213). The invention tracks an original speculative exception which occurs when a speculative instruction whose operand(s) do not have any exception bits set encounters an exception condition. Speculative exception resolution is triggered when a non-speculative instruction - which is in the taken path of a conditional branch -uses an operand from a register having ist exception bit set. The presence of an exception condition and a non-speculative instruction yields an exception signal (220) to exception resolution (204). Speculative exception resolution (204) includes responding to output signals from the extra register and extra exception bit for correcting (204) the exception condition which caused the exception and re-executing (208) the instructions which depended on the results of the instructions causing the speculative exception.

Patent CA-2210954-A1 (CA)
Title: Vehicle steering correction system
Inventor: CLINKSCALES JAMES K
IPC: B62D6/04
Filed: 1997-07-31
Abstract: The correction system of this invention simulates a power steering leak which the driver can manually adjust or automatically tune to offset vehicle drift and/or pull generated by road crown, wind, vehicle alignment, and tires during straight ahead driving.  The drift and pull correction system taps into the bypass line of a vehicle's power steering system and can be added to the vehicle as an aftermarket device.  For example, the standard rack or power gear, the power steering pump and reservoir and the steering assembly of the power steering system can be used in combination with the addition of correction lines and correction valves of the steering correction system to correct the vehicle's steering system for "straight ahead driving" without operator assistance.    The magnitude of the drift and/or pull is a direct function of the magnitude of the leak and the back (parasitic) pressure in the system.  The correction system bypasses hydraulic fluid to one side of the power steering piston causing the steering system to input a steer angle change to the wheels until the added steering force generated on the vehicle is adequate to balance the forces and moments generated during straight ahead driving.

Abstract: Disclosed is laminate flooring and other articles with tongues and grooves for joining sections of the flooring or articles and a method of making the tongue and groove joints. The lower surfaces of the tongues and grooves are indexing surfaces for aligning the wear surfaces of the flooring sections. The tongues and grooves are made such that when the tongue is fully inserted into the groove, a continuous space is formed between the upper surface of the tongue and groove. The grooved edges arecut at an acute angle to the surface. This provides a space between the upper surfaces of the tongue and groove and between the edge surfaces above the tongues and grooves toward the wear surfaces of the flooring sections. Glue in the joint, upon curing, resists penetration of moisture and increases the strength of the joint.
