Patent EP-0304794-A3 (EP)
IPC: G01N31/00
Filed: 1988-08-18
Abstract: A method for the quantitative determination of 
lithium in a liquid test sample employing turbidi­
metric or nephelometric techniques to measure the 
maximum rate of change in the optical density of a 
reaction mixture containing precipitated lithium. 
The lithium is precipitated by a lithium 
precipitating reagent to result in dispersed, 
suspended particles, and the maximum rate of change 
in optical density determined to provide. a linear 
dose response which can be quantitatively 
correlated to the amount of lithium present in the 
test sample.

Title: Foldable cart for shopping
IPC: B62B1/12
Filed: 1988-09-14
Abstract: Foldable cart for shopping. It is a foldable cart with a rigid base for reinforcement of the bag bottom, which base has articulated thereto both frameworks (1, 2) carrying the corresponding wheels on which the bag (6) leans in the unfolded position for its transport, which frameworks allow the wheels to be folded beneath the rigid base, whilst the seizing frameworks can be extended and folded by in-parallel sliding in order to allow the extension thereof for pulling the cart or folding it in the form of a bag of reduced size for its hand transport. One of the frameworks is attached to the upper zone of the bag, pulling the latter for its extension or folding, whilst the other one has, close to its articulation axle at the resistant base of the bag, a prismatic piece (7) provided with one or two lugs (8) which pass through both slots foreseen in the housing for the articulation of the frames and the wheel frame works to extend the wheels automatically. There are in the guiding sleeves of the frames and in the articulation housing, means for the retention of the unfolded position and, in the resistant base, other means for fitting said frames in the folded position.

Title: Armature of a building inlet for a gas or water supply pipe
IPC: F16L5/00
Filed: 1989-09-12
Abstract: The armature of a building inlet consists of a protective pipe (1) made of metal which is held in the building wall and of a metallic inner pipe (6), guided in the said protective pipe, having a terminal skirt-type piston (8). Connected to the free end of the inner pipe (6) is the underground medium pipe. The skirt-type piston (8) contains in the cylinder wall a transverse bore (9) which, in the starting position (open position) coincides with a wall bore (10) in the protective pipe (1), to which the building pipe can be connected. An outwardly projecting piston rod (13) with a marking (17) for position indication emerges from the head end of the skirt-type piston (8). In the event of a pulling or pushing action on the underground supply pipe, the inflow of medium is automatically cut off by displacement of the skirt-type piston (8). The particular operating condition of the armature can be detected from inside the building by visually checking the position of the piston rod (13). In the event of a response in which the medium has not yet been shut off, it is thus possible to introduce suitable countermeasures in good time. <IMAGE>

Abstract: A system and method for installing a nozzle dam 
unit (26) in a nuclear steam generator having a head 
(12) including a head internal surface, a manway (14) 
penetrating the head, and a nozzle (16) penetrating the 
head. The system comprises a manipulator (76) adapted 
to be passed through the manway and having one end (82) 
adapted to be attached remotely to the head internal 
surface and a free end including a clamp member (104). 
A plurality of nozzle dam segments (52, 54, 56) are 
each sized to pass through the manway and carry means 
thereon (114, 116) for engaging at least one other 
segment, the segments when fully engaged to each other 
forming a dam subassembly sized to pass into and seat 
against the nozzle. The manipulator is controlled so 
that the clamp member grasp and supports one of the 
dam segments within the head until the subassembly is 
formed within the head, and then is translated within 
the head until the dam subassembly seats within the 
nozzle.
Patent EP-0378776-A3 (EP)
Title: Method for controlling the establishing of connexions in a communication exchange
IPC: H04Q11/04
Filed: 1989-11-13
Abstract: In a communication exchange connecting through in accordance with the time-division multiplex principle, the setting up of connections is to be controlled in such a manner that the central processor is relieved of control processes used for pathfinding and time slot allocation. The through-connection time (time slot) and the through-connection path are exclusively determined by the decentralised group processors. The time-slot and bus allocation information items are exchanged directly between the group processors involved. Since the central processor is now only used for determining the destination and only receives setting commands for connecting through connections in space-division switching stages, the relief achieved is of such a magnitude that no bottlenecks occur even in relatively large communication exchanges. <IMAGE>

Filed: 1989-11-13
Abstract: An improved process for separating a hydrocarbon bearing feed gas containing methane and lighter, C2 (ethylene & ethane) and heavier components into a fraction containing predominantly methane and lighter components and a fraction containing predominantly C2 and heavier hydrocarbon components including the steps of cooling and partially condensing and delivering the feed stream to a separator (44) to provide a first residue vapor and a C2-containing liquid, directing a portion of the C2-containing liquid into a heavy ends fractionation column (56) wherein the liquid is separated into a second hydrocarbon bearing vapor residue and a C2 containing product, conducting a portion of the first residue vapors with at least part of the partially condensed second residue into a light ends fractionating column (52) to thereby obtain third residue vapors and liquids, supplying the liquids recovered from the light ends fractionating column to the heavy ends fractionation column as the liquid feed thereto and directing part of the C2 containing liquid from the first step into intimate contact with the second residue, which liquid provides additional liquefied methane which acts with the partially condensed second residue as a direct contact refrigerant to thereby condense C2 and heavier components while the methane itself is evaporated in the light ends fractionation column.
