Abstract: A device (10) is described for the selection and control of 
the gears in a gearbox of a vehicle, of the type in which a 
lever (1), actuable by the driver, acts, by means of a link (11), 
on the gear selector forks.  
     The link (11) is essentially constituted by a single fork 
actuating rod (3); such rod (3) is mounted rotatably and 
slidably in a longitudinal sense about its own axis of 
symmetry (a) and carries radially a coupling element (4). This 
latter cooperates with an arm (17) of the lever (1) and from it 
is able to receive forces in two perpendicular directions 
which cause, in the said rod (1), movements of translation or 
rotation about the said axis (a).

Abstract: Beschrieben ist ein Kunststoffverschluß zum Aufsetzen 
auf den in Achsrichtung umgebogenen Rand einer Öffnung 
in der Wandung eines Behälters und zum unlösbaren 
Verbinden mit diesem, wobei der Verschluß (1) einen 
Aufsetzflansch (4), einen wulstartig vorstehenden Fuß (6) 
und dazwischen eine diese trennende Ringnut (5) aufweist.  
     Um den Sitz des Kunststoffverschlusses zu verbessern, 
ohne daß die erforderlichen Kräfte beim Einsetzen des 
Verschlusses zu hoch werden, ist erfindungsgemäß vorgese­
hen, daß der Fuß (6) am Umfang im Abstand voneinander 
angeordnete, vorstehende Nocken (7, 7′) aufweist. Dies führt 
zu einer besseren Befestigung des Verschlusses im Oberbo­
den des Behälters. Hierdurch wird ferner verhindert, daß 
beim Hochziehen des balgförmigen Ausgießteiles des Ver­
schlusses der Verschluß aus seinem Befestigungssitz verse­
hentlich herausgerissen werden kann. Beim Fall gefüllter 
Behälter springt der neue Verschluß auch kaum noch aus der 
Öffnung heraus, wenn diese durch den Fall deformiert wird.

Abstract: A scheme for addressing memory cells in random ac­
cess memory arrays includes bitlines (BL1, BL2) divided 
into a plurality of segments. Each pair of bitlines (BL1, BL2) 
has a sense amp at each end coupled to both bitlines in the 
pair. Word lines (WL) address memory cells (53, 55) coupled 
to each bitline of the pair. When a pair of memory cells (53, 
55) is accessed, the bitlines (BL1, BL2) are electrically di­
vided so that one memory cell (53) is coupled to one sense 
amp (1) through one bitline (BL1) and the other memory cell 
(55) is coupled to the other sense amp (2) through the other 
bitline (BL2). The memory cells (53, 55) can be coupled to 
the bitlines through segment lines (52) with each segment 
line (52) connecting to a subset of the memory cells to a 
bitline (BL1, BL2) in order to reduce capacitances presented 
to the sense amps. An alternating linear array of sense 
amps and bitline pairs can be used to increase overall 
density of the memory array by allowing sense amps to 
access more than one bitline pair. The bitlines are address­
ed so that each sense amp receives data from only one 
bitline pari at a time.

Abstract: The present invention relates to novel electrostatic charge 
transfer media and a method for preparing said media.  
     In electrophotography or electrostatic printing, the prior 
art techniques for accomplishing charge transfer from one sur­
face to another involves either: (1) conduction of electric 
charges across an air gap, or (2) direct charge transfer if the air 
gap is eliminated. While the air breakdown charge transfer 
technique is simple, it does not provide high resolution [less 
than 80 line pairs per millimeter (1p/mm) can be achieved] or 
continuous tone gray scale reproduction. The presently known 
techniques for direct charge transfer require a very smooth sur­
face, a transfer liquid interfacing the donor and receptor films, 
very high pressures to eliminate the air gap, or a surface pro­
vided with a multitude of conductivity sites. However, most 
direct charge transfer techniques are too slow for many com­
mercial applications, e.g. duplication of customers' checks by 
banks.  
     This invention involves an article having improved elec­
trostatic charge transfer properties. The improvement in 
charge transfer properties results from subjecting a layer of 
photoconductive-insulative material or dielectric material on 
the charge donor or a layer of dielectric material on the charge 
receptor, or both layers, to plasma treatment process to pro­
vide an oxygen-enriched surface to the photoconductive-insu­
lative layer and/or the dielectric layer.  
     The articles of this invention provide transfer of charge 
with high efficiency, high resolution, and at much higher 
speeds than has previously been possible.

Title: High concentration encapsulation by interfacial polycondensation
IPC: A01N25/28
Filed: 1985-06-11
Abstract: This invention relates to a process for encapsulation, and particularly to the production of small or minute capsules constituted by a skin or thin wall of polymeric material e.g., polyurea, polyamide, polysulfonamide, polyester, polycarbonate, or polyurethane, which involves first providing an aqueous solution (continuous phase liquid) containing an emulsifier which is a water soluble, alkylated polyvinyl pyrrolidone polymer which will form a stable oil-in-water emulsion under the process conditions described herein. A discontinuous (immiscible or organic) phase liquid containing a water-immiscible material which is the material to be encapsulated, plus a first shell wall component; is dispersed in the aqueous liquid to form an oil-in-water emulsion. The second shell wall component is added to the oil-in-water emulsion whereupon the first shell wall component reacts with the second shell wall component to form a solid polycondensate shell wall about the material to be encapsulated. The capsules formed may be directly used as in the form of an aqueous suspension.

Title: A method and apparatus for the determination of electrochemically active components in a process stream
IPC: G01N27/34
Filed: 1987-07-21
Abstract: A method and apparatus for determining electrochemically active components in a process stream is disclosed. The method comprises the steps of providing a sample in which the components are contained, and depositing the components onto a working electrode, altering the environment of the working electrode so that it is immersed in a supporting electrolyte by effecting a matrix exchange and stripping the deposit electrochemically active components from the working electrode into the supporting electrode. A method and apparatus utilize a measurement cell which comprises a vessel (10) for containing the supporting electrolyte and a mercury electrode (150). A flow injector (16) is used to inject a flow with the sample electrolyte into the vessel so that the sample electrolyte surrounds the mercury drop electrode and then sinks away from the mercury drop electrode (150) to the bottom of the vessel where it is removed via an outlet (20) to thereby leave the mercury electrode (150) immersed in supporting electrolyte. The deposited impurities are stripped from the supporting electrolyte using variable time domain transient electrochemical stripping voltammetry. The sequence of steps including the deposition of the impurities from an injected flow of electrolyte sample are repeated under microprocessor control (50).

offshore wells. An inner casing string (24) which includes a 
running hanger body (20) is suspended by a split ring hanger (40) from 
an outer casing (44) which includes a receiving hanger (52). The 
receiving hanger (52) and split ring hanger (40) have complementary 
profiles (58,60) which lock together when the split ring (40) expands. 
The split ring (40) is carried down through the outer casing (44) 
contracted into an annular recess (28) in the running hanger 
body (20), and temporarily restrained to the lower end of the 
recess (28). When the running hanger body (20) reaches the receiving 
hanger (52), the split ring (40) expands so that the complementary 
profiles (58,60) engage and suspend the ring from the receiving 
hanger (52). The temporary restraint is released, and the 
running hanger body (20) descends a further short distance until 
the upper end (30) of the annular recess lands on the ring (40) to 
suspend the inner casing string (24) on the ring (40). Two annular 
arms (48,46) on the recess (28) apply positive locking to the split ring 
hanger (40) in this position. With dual positive locking, the 
split ring hanger regains hoop strength.
