Inventor: NORDMANN KURT DR
IPC: G08B13/196
Filed: 1991-02-04
Abstract: In order to combine an optimal deterrent effect with monitoring possibilities a monitoring installation includes a plurality of rotatable monitoring units, which units have two parallel slot shaped openings. These openings extend along a bottom circular sector. A camera lens and a loudspeaker arranged in a louvre are located in every slot shaped opening. These are traversable at least over part of the extent of the circular sector. A potential thief is given the impression of an uninterrupted monitoring. He is deferred further by the loudspeakers. These can at the same time be used for transmitting alarms, announcements or customer information.

Abstract: In a four-wheel drive power train of a motor vehicle two hydraulically operated clutches (25, 43) are used. The first clutch (25) serves as separating clutch for a first vehicle axle (5), the second clutch (43) as locking clutch for the locking of a locking system (10) by means of which the second vehicle axle (1) can be connected as a function of the speed. By means of a first hydraulic piston (49) the separating clutch (25) can be closed against the force of a disc spring (51) whilst by means of a second hydraulic piston (48) concentric with the first piston the locking clutch (43) can be opened against the force of a disc spring (46).

Abstract: In the case of the known discontinuous drainage processes in which the operating pressure has to be reduced to the surrounding pressure between the removal of the drained sludge cake and the refilling of the drainage apparatus, the filtering action can quickly drop off since fresh raw sludge reaches the drainage chambers only by passing already used filtering surfaces and pushing along in front of it a portion of already predrained sludge cake. The novel process is intended to permit a continuous operation with uniform pressure level and a constant, high filtering capacity while at the same time reducing the possibility of faults arising to a minimum. This is achieved in that the fresh raw sludge (21) is fed at constant pressure in the opposite direction in each case to the direction of movement of the piston (8), in particular in the immediate vicinity of the piston, to the filtering surface shortly after the latter has been swept over by the piston and thereby cleaned. The process and the apparatus for carrying out the process thus make it possible for aqueous sludges to be drained continuously by means of pressure. <IMAGE>

Abstract: Biologically active reagents are prepared from particles of copolymers having highly reactive carboxy or equivalent groups. The reagents are prepared by covalently attaching biologically active substances, for example antibodies, to the particles, directly or indirectly through highly reactive carboxy groups on the particle surface. These reagents are used to advantage in analytical elements, methods for the detection of specific binding ligands (such as immunological species) and immunoassays, and in purification methods as affinity chromatography reagents.

Abstract: An echo canceller comprises a frequency-domain adaptive filter (8) and a time-domain programmable filter (9) for obtaining an estimate of an echo signal between a loudspeaker (4) and a microphone (5). By subtracting this estimate from the output signal of the analog-to-digital converter (6), an output signal r(k) is obtained which is essentially free from echoes. An accurate estimate of the echo signal can only be obtained if no near-end speech signal is present at the output of the analog-to-digital converter (6). If a near-end speech signal is present, the transfer of filter parameters from the frequency-domain adaptive filter (8) to the time-domain programmable filter (9) is blocked. A near-end speech signal is assumed to be present if the ratio of the signal power in signal z(k) to the signal power in signal y(k) exceeds a specific threshold.

Abstract: A passive refrigerant retrieval and storage apparatus (10) is shown for retrieving refrigerant from a cooling system (48) prior to servicing the cooling system (48). The passive apparatus (10) includes a coil collector tube (20) within an insulated housing (14) with an outlet (26) from the collector tube (20) passing through a metering valve (28) into the housing (14). The collector tube (20) is connected to the condenser outlet (62) of a cooling system and the system compressor (50) operated to pump pressurized liquid refrigerant into the collector tube (20). A small portion of the refrigerant is discharged through the metering valve (28) into the apparatus housing (14) where it is evaporated and causes extreme subcooling to the refrigerant in the collector tube (20). A return line (46) from the housing (14) to the inlet side (64) of the compressor returns the evaporated refrigerant to the cooling system (48). Gradually the cooling system (48) is starved for refrigerant such that the pressures in both the high pressure side and low pressure side of the cooling system (48) gradually decrease, decreasing the pressure of refrigerant within the collector tube (20) and housing (14) of the retrieval apparatus (10) such that the liquid will no longer evaporate, trapping the refrigerant in the retrieval apparatus (10).

Inventor: GITLIN RICHARD D
IPC: H04Q11/00
Filed: 1991-12-03
Abstract: Currently, with optical time division multiplexing, a switching node is operated at the peak transmission rate. For example, if the data transmission rate is 10 Gbps, the line cards in the switching circuit are also required to operate at this rate despite the fact that the switching node does not actually need to access the data at this rate. Thus, the electronics, which includes the line cards at the switching node is expensive and less reliable than a low-speed design. In this invention, the requirement of operating the switching node electronics is eliminated by encoding the packet header field (22) at a lower rate than the information in the data field (24). As a result, the line cards need only operate at the lower header rate. This is possible because the switching node does not need to process the data portion of the packet, but only the header information. The high-speed data portion (24) of the packet is not optically to electrically converted at the switching node, but it passes almost transparently through the switching node. The invention also discloses overlapping several logical networks on the same physical network.

Abstract: A cavity (11), in which is established a high-frequency electromagnetic field, is arranged, on the insertion path of the portable object into the reader, upstream from the pickoff device (3) provided on the reader for picking off the electrical signals on the electronic circuit (21) of the portable object. If a conducting connection (25), provided by a fraudster in order to deceive the reader with the aid of a portable computer, for example, crosses this cavity (11), it behaves like an antenna, which senses a signal at the frequency of the electromagnetic field. The signal sensed is found amoung the signals picked off and its detection controls inhibition of the reader. The invention applies especially to readers for portable objects known by the name of "chip cards". <IMAGE>
