Patent EP-0077044-A3 (EP)
Title: Method to passivate metals deposited on a cracking catalyst during reduced crude processing
IPC: C10G11/18
Filed: 1982-10-08
Abstract: Contaminating metals including nickel, vanadium, iron and copper are deposited on a fluid cracking catalyst during the processing of carbo-metallic oils such as reduced crude or topped crude. These contaminating metals lead to undesirous side reactions such as dehydrogenation, coking and methyl clipping which adversely affect conversion and gasoline selectivity. An improved method and process is described for passivating these metals by treatment with a reducing gas such as ammonia. The ammonia is added as gaseous ammonia or in the presence of diluents such as nitrogen, carbon dioxide, flue gas, fuel gas and steam. The reaction of ammonia with vanadium produces vanadium nitride which is water insoluble and facilitates the disposal of high vanadium containing spent catalyst by landfill techniques.

IPC: A61F13/15
Filed: 1982-02-19
Abstract: Disposable diapers provided with a two-element breathable backsheet. The two elements are a vapor pervious, relatively liquid impervious outer sheet and a liquid impervious inner panel. An absorbent core is the third necessary element of the disposable diaper. The inner panel is placed between the outer sheet and the absorbent core in the crotch region of the disposable diaper. There is no requirement that the inner panel be affixed to the outer sheet in any manner other than to insure the maintenance of their relative orientations during use. The disposable diaper can be provided with an optional topsheet disposed on the absorbent core on the side opposite the breathable backsheet.

Title: Method of producing alkali-soluble cellulose derivative
IPC: C08B15/06
Filed: 1982-01-27
Abstract: An alkali-soluble cellulose derivative is produced by treating cellulose with liquid ammonia having urea dissolved therein, removing the ammonia, resulting in cellulose having urea distributed therethrough, and heating the thus obtained cellulose-urea to cause reaction between the urea and cellulose and form alkali-soluble cellulose carbamate. This cellulose carbamate can be precipitated from alkaline solution in the form of cellulose carbamate film or fibre.

Title: Electrographic touch sensor
IPC: G06F3/033
Filed: 1985-12-20
Abstract: A resistor electrode type touch sensor having enhanced area of linear response by reducing the bow in perimeters of the sensor and the method of accomplishing the same. A resistive coating is applied to one surface of a substrate. Within this coating orthogonal electrical fields are produced to give coordinates of a selected position. Overlying, but spaced from, the resistive coating is a flexible pick-off sheet having a conductive layer facing the resistive layer which will contact the resistive coating when the pick-off sheet is touched at a selected position. A resistance element is positioned proximate, but insulated from, the perimeter of the resistive coating. Electrodes of a selected effective size and spacing are located along selected paths proximate the edges of the resistive coating. Each electrode is attached to the resistive coating and connected to selected positions along the resistance element to provide selected voltages to the resistive coating. The effective size and spacing of the electrodes, and the positions of connection to the resistance element, are selected to produce an effective voltage gradient at the electrodes that progressively decreases from corners of the sensor to the center line of each edge of the sensor to counteract any voltage drop along the resistance element when voltage are applied thereto so as to substantially eliminate the bow of electrical fields produced in the resistive coating.

Patent EP-0190753-A3 (EP)
IPC: C04B35/657
Filed: 1986-02-06
Abstract: A novel method of making a refractory material 
is disclosed comprising the steps of providing an electrical 
arc metal furnace, charging that furnace with a charge of 
refractory oxide, and selecting voltage, amperage and 
electrode spacings to create novel "hum and scum" melt 
conditions. This hum and scum condition is maintained until 
said charge is substantially melted. The described 
technique is particularly useful for melting magnesia chrome 
materials to produce fusion cast refractory products which 
are highly reduced and quite dense. The elaboration of 
this product requires higher energy input per pound concurrent 
with an increased consumption of reducing materials 
compared with standard preparation conditions. The 
resulting product exhibits higher oxidation weight gains, 
higher densities, lower porosities, high cold crush 
strengths, more thermal shock resistance, and better 
corrosion-erosion resistance than similar magnesia chrome 
refractory products fused using prior "arc and bark" 
processes.

IPC: H04L12/64
Filed: 1986-07-24
Abstract: This invention provides a port circuit (950) for coupling an 
end-user instrument with a port of a communications system. 
The communications system transmits and receives bursts 
via the port. A burst is a plurality of bytes which may repre­
sent, for example, a block of data or a spurt of voice energy. In 
a preferred embodiment, the port circuit comprises a port-­
interface (954), an end-user interface (958), and a micro­
processor (952) coupled between the port and end-user inter­
faces. The microprocessor has intelligence for transmitting 
and receiving bursts to and from the system. The micro­
processor also provides intelligence for originating and trans­
mitting control bursts to the system and receiving and im­
plementing control bursts from the system. A control burst is 
a message sent between control processors for administrat­
tive purposes. The port circuit as described is more flexible 
than the traditional line circuit because of the presence of the 
intelligent processing means. When the port circuit is adapted 
for coupling with an end-user voice instrument, the micro­
processor includes a voice/silence detection algorithm. A port 
circuit may be adapted to provide one or more BORSCHT fun­
ctions depending on the requirements of the particular type of 
end-user instrument. In various embodiments, a port circuit 
may include local generation of ring voltage (966), local tone 
detection (964), and/or a loop-back testing capability (968). A 
port circuit, as described herein, may be located remotely with 
respect to the communications system, perhaps on the user 
premises or even within the end-user instrument.

IPC: B63B23/40
Filed: 1986-11-19
Abstract: A system for retrieval and launching of lifeboats, buoys 
or the like includes a lifeboat provided at a point centrally 
above the hull, with a rigid, inverted V-shaped suspension 
member adapted to be engaged by a suspension hook the 
structure of which allows that it can be engaged with the lift­
ing member or eye without assistance from the lifeboat it­
self. The hook is also provided with means for preventing 
inadvertent release thereof, including a downwardly direct­
ed nose portion. The engagement of the hook with the sus­
pension member without assistance from the lifeboat is 
made possible by rolling bars which cause the hook to turn 
into engagement with the rigid lifting eye of the boat as the 
hook is lowered into contact therewith. When launching life­
boats or the like, a loosely suspended secondary hook, held 
by the main hook, holds the boat. The secondary hook is 
provided with a tag line which, when pulled, results in 
swinging the secondary hook relative to the main hook thus 
moving the hook away from the lifting eye of the lifeboat. In 
another embodiment of the hook, a scissors arrangement is 
provided which facilitates the release of the hook on launch­
ing the boat, while providing, in the second mode, a rigid 
crane hook structure. The system presents a simple struc­
ture of the components but it enables the operation of a life­
boat retrieval and launching system without the need of any 
assistance at the end of the floating boat.
