Title: Recovery of hydrocarbons from hydrocarbon contaminated sludge
Inventor: SURY KOHUR N
IPC: B03B9/02
Filed: 1990-11-13
Abstract: A process is disclosed for the removal of hydrocarbons such as bitumen or heavy fuel oil from hydrocarbon contaminated sludge, or particulate solid material or the like non-homogenous material after appropriate conditioning, such as by ball milling, with the conditioned material being aerated and then fed substantially tangentially into a substantially vertical cyclonic separator vessel to cause the hydrocarbons to which air bubbles have become attached to tend to float as a froth to the top of the vessel, with the remaining solids sinking to the bottom of the vessel.  The hydrocarbon containing froth is then removed from the top of the vessel, and the remaining solids removed from the bottom of the vessel.  This pneumatic flotation process obviates the need to add chemicals such as wetting agents or promoters.
Patent CA-2033308-A1 (CA)
Inventor: SERAFINI TITO T
IPC: C08F290/00
Filed: 1990-12-27
Abstract: Polyimides having a high thermal and oxidative stability are prepared by reacting a mixture of monomers comprising (a) a dialkyl, trialkyl, or tetraalkylester of an aromatic tetracarboxylic acid, (b) an aromatic diamine, and (c) an end cap compound.  The ratio of (a), (b), and (c) is chosen so that upon heating the mixtures, low molecular weight prepolymers are formed, the prepolymers having only one end cap radical and being suitable for chain extension and crosslinking to form high molecular weight, thermally stable polyimides.  Upon heating, the prepolymers form polyimide resins, which can have Tg in excess of 600°F and superior physical properties.

Abstract: FMC Corporation                    Munich, 4.4.1990 F11635 Bd/wu ABSTRACT      An apparatus for rolling up web material, particularly bags consisting   of plastics films and connected together in strip form, wherein the web material can be wound on a plurality of winding mandrels in a winding station in such a manner that a winding mandrel in a waiting position (waiting winding mandrels is disposed adjacent to the web material being supplied, in front of a winding mandrel (take-up mandrel) in a winding position, and after the web material has been severed transversely in front of the winding position, the beginning of the length of web following on the point of separation is supplied to the waiting winding mandrel, while, as a result of lifting the beginning in relation to the spaced apart end of the length of web running on ahead and blowing compressed air under the raised beginning, the latter is brought up to the rotating waiting winding mandrel and is entrained by this until, after a minimum package thickness has been reach on the waiting winding mandrel this is transferred into the winding position and another empty winding mandrel is transferred into the waiting position, whereupon the full package on the winding mandrel is lifted from the winding mandrel by blowing compressed air out of radial nozzles provided in the winding mandrels, and is withdrawn from the winding mandrel.   An adjustable reduced pressure can be connected to the waiting winding mandrel in such a manner that at the time when the beginning of the length of web following on the point of separation is lifted, this beginning is pressed against the surface of the waiting winding mandrel by means of the radial nozzles for the purpose of entrainment, while as a result of the adjustment of the height of the reduced pressure, the friction between the surface of the waiting winding mandrel and the beginning of the length of web increases steadily until there is entrainment.

Patent CA-2043200-A1 (CA)
Inventor: BARON TIBOR
IPC: F16K31/06
Filed: 1991-05-24
Abstract: An electromechanical valve apparatus has an electrical winding and a magnetic flux circuit defining a flux path therefor which includes a plurality of adjacent magnetic segments. The segments include a generally cylindrical center segment with a fluid passage, an end segment, an outer segment and a magnetic armature member. At least one of the segments is physically translatable within the valve apparatus along the flux path to adjust a portion of one of the magnetic segments that is in the flux path and the extent of an air gap adjacent the translatable segment.      The apparatus includes a non-magnetic seat member which is located near or at the paint of highest flux density along the longitudinal axis through the electrical winding. The armature is preferably an elongated member with its closed end located within the electrical winding near the non-magnetic seat member.      The seat member and armature are enclosed within a chamber defining body such as the bobbin. In an alternative embodiment, a flat disc member is located at the base of the armature. The flat disc is retained within the base of the armature. When no current is flowing in the winding, the flat disc member rests against an armature seat formed in the chamber defining body and prevents leakage of air from the fluid chamber. A further alternative embodiment allows ready calibration of the valve apparatus via a calibration fixture adopted to translate one of the magnetic segments within the flux path.

Title: Twin hose coupling
Inventor: HOHMANN RALF
IPC: F16L39/00
Filed: 1991-11-12
Abstract: ABSTRACT           A device for simultaneously coupling two pipes with two hoses has a discrete tubular connector for each hose, and each connector has flexible arms with pallets which can engage external retainers on the pipes.  The connectors are more or less permanently secured to the respective hoses and are separably connected to each other by a flexible holder having C-shaped collars receivable in external grooves of the connectors and one or more flexible webs which connect the collars to each other. The flexible holder compensates for eventual departure of the distance between the pipes from an optimum distance and/or for absence of exact parallelism of the pipes with one another.  When a connector is separated from the holder, it can be used as a constituent of a simple hose coupling, namely to connect the end portion of a hose to a nipple, to a pipe or another tubular component.

IPC: F01M1/24
Filed: 1992-04-14
Abstract: Fluid pressures in an internal combustion engine are monitored by two diaphragm operated valves and open either valve when abnormal pressures are sensed to shut down the engine.  Each valve is a sleeve valve slidable on a stem and normally latched to the stem.  The stem carries a reset button and is spring biased to hold the valve in closed position.  A valve is released from the stem when abnormal pressures are detected and the valve is spring biased to the open position.

Title: Apparatus and method for maintaining cache/main memory consistency
Inventor: PATEL BHIKOO J
IPC: G06F12/08
Filed: 1990-03-28
Abstract: A write-through cache (14) wherein for write operations of less than a word in length the write data stored within a FIFO memory device (18) associated with a first bus agent reflects the result of a read/modify, write type of access wherein a byte or half word has been merged by a local processor (12) with a cache word. Memory control lines driven to a system bus (20) indicate to a memory controller (22) that a write operation is to be accomplished as a word write, thereby eliminating the additional time required to achieve a read/modify/write memory controller cycle. To prevent the occurrence of a problem wherein another bus agent, such as another CPU or an I/O device, writes to a system memory (24) during an interval of time that the word of data is temporarily buffered within the FIFO there is provided circuitry for detecting an external write made to the system memory. Circuitry is also provided for detecting that the FIFO has data stored within and for changing thememory command lines to indicate, instead of a word write, a byte write of a half word write operation.
