Title: Improved vent for enclosures
Inventor: STEELE EDWARD A
IPC: F24F13/08
Filed: 1992-09-17
Granted: 2003-05-06
Abstract: A vent arrangement is provided for enclosures that prevents the entry of water into the enclosure and that also prevents the penetration of a pry bar or probe wire.  The vent arrange-ment includes a first predetermined pattern of openings of predetermined shape and dimensions provided at the exterior wall of the enclosure. The dimensions of the openings and the spacing between the openings are determined relative to the pry bar and the material in which openings are formed, such that the pry bar cannot fully enter the openings and such that the portion of the pry bar that can be applied to the openings does not cause any substantial deformation of the material surrounding the openings that could permit widening of the openings so as to allow full entry of the tip of the pry bar. In a preferred embodiment, to permit the maximum percentage area of openings within the pattern of openings while achieving the desired tamper-resistance characteristics, the first predetermined pattern of openings includes staggered rows of openings such that the openings of adjacent rows are not aligned. The vent arrangement also includes a baffle plate spaced behind the predetermined pattern of openings. The baffle plate includes facilities to freely pass air, but prevents the ingress of any water that may enter through the first predetermined pattern of openings. The baffle plate is arranged to direct all such water out through the bottom of the first predetermined pattern of openings. In a preferred arrangement, the vent arrangement also includes facilities to prevent the ingress of a probe wire beyond the baffle plate and into the enclosure even if the probe wire passes into the venting arrangement beyond the first predetermined pattern of openings. In a specific embodiment, this is achieved by the provision of a double layer of wire-mesh screen or the like disposed within the vent arrangement between the first predetermined pattern of openings and the baffle plate. The double layer of wire-mesh screen is arranged in a closed path in the shape of a cage or the like.

Abstract: By this method, the masses and the frictional forces of all movably interconnected installation parts are referred to the door leaf (2) in a sliding door system (1) and ascertained numerically with the aid of the closing weight (G). For this purpose, the door leaf (2) is subjected to an opening learning travel (öL) and a closing learning travel (SL) and in that case guided without drive over a respective test section TS1 and TS2 and a first energy balance (EB1) and a second energy balance (EB2) respectively are set up from then measured kinematic parameters (v1, v2, s1) and (v3, v4, s2). The energy balances (EB1, EB2) contain the potential energy (Ep) of the closing weight (G) with positive or negative sign and in combination result in special formulae for the numerical values of the dynamic mass (md) and the mean frictional force (Fr*) of the sliding door system (1). The microprocessor (3.1) and the incremental transmitter (3.2) of the door drive (3) serve for the measuring, storing and processing of the kinematic parameters as well as for the computation of the numerical values of the dynamic mass (md) and the mean frictional force (Fr*). The method is generally applicable to mass systems and their physical characteristic values and is suitable particularly for the ascertaining of the closing speed (vsmax), which is the maximum permissible for reasons of safety technique, of sliding and pivoting doors.

Abstract: Amines such as methyl amine are reacted with materials such as reducing sugars in hydroxy solvents such as methanol to prepare N-alkyl polyhydroxy amines. Accordingly,glucose is reacted with methyl amine and the resulting adduct is hydrogenated to yield N-methylglucamine. The N-alkyl polyhydroxyamines can be subsequently reacted with fatty esters to provide polyhydroxy fatty acid amides useful as detersive surfactants. Thus, detersive surfactants are available from non-petrochemical precursors such as sugars and sugar sources such as corn syrup, and fatty acid esters derivable from various fats and oils.

Title: Call handoff in a wireless telephone system
Inventor: FARWELL CHARLES YEOMANS
IPC: H04L7/04
Filed: 1993-08-31
Granted: 1999-09-28
Abstract: Signaling a mobile unit to transmit a synchronization pattern with voice information upon detecting from the signal strength of the wireless mobile unit by a base station that the mobile unit is approaching a minimum threshold. Where the voice information is initially being transmitted in a set of frequency hopping channels using spread spectrum transmission, the synchronization pattern is transmitted in one or more of the set of frequency hopping channels. In addition, the base station alerts a system controller to this fact, and the system controller requests that neighboring base stations monitor the set of frequency hopping channels being transmitted by the mobile unit. In order to synchronize to the mobile unit, the base stations utilize the synchronization pattern to come into synchronization with the mobile unit. The system controller transfers (handoff) the wireless mobile unit to the base station which is receiving the strongest signal strength.
