Patent CA-1319318-C (CA)
Title: Conduit construction means
Inventor: SANDERS ROSS P
IPC: F42D1/18
Filed: 1988-10-21
Granted: 1993-06-22
Abstract: ABSTRACT         "Conduit Constriction Means"      A means for the constriction of fluid movement in a conduit comprises a tubular wall-gripping member which is freely movable within the conduit but which is capable of lateral expansion to grip the conduit wall.  The wall-gripping member has an exterior (wall-gripping) surface and an interior surface which is so shaped that, when the wall-gripping member is prevented from moving in the conduit, the action of the fluid, either directly or indirectly, on the interior surface causes expansion.  In a preferred embodiment, a tube is segmented into four segments which are secured by circumferential elastic bands.  The interior surface is frusto-conical and the action of fluid on a similarly-shaped frusto-conical vessel placed therein causes expansion.  The means is particularly useful in the explosives industry for providing "air-decking" in vertical blast holes.

Abstract: C.3219 ABSTRACT                        LIQUID DETERGENTS      Improved flexibility in incorporation of soluble salts in structured aqueous liquid detergents is provided by incorporating a surfactant with a salting-out resistance greater than or equal to 6.4 and which has an average alkyl chain length greater than 6 C-atoms provided that the liquid yields substantially no clear liquid active rich layer upon centrifuging at 750G for 20 hours at 25°C. The salting-out resistance is the minimum amount in grams equivalent of trisodium nitrilotriacetate added to 1 litre of a 5% aqueous solution of the surfactant at room temperature, to achieve phase separation as evidenced by cloudiness.

Title: Topographic pattern delineated power mosfet with profile tailored processed source
Inventor: MEYER THEODORE O
IPC: H01L21/033
Filed: 1989-04-21
Granted: 1992-07-14
Abstract: TOPOGRAPHIC PATTERN DELINEATED POWER MOSFET    WITH PROFILE TAILORED RECESSED SOURCE       ABSTRACT OF THE DISCLOSURE A dopant-opaque layer of polysilicon is deposited on gate oxide on the upper substrate surface to serve as a pattern definer during fabrication of the device.  It provides control over successive P and N doping steps used to create the necessary operative junctions within a silicon substrate and the conductive structures formed atop the substrate.  A trench is formed in the upper silicon surface and a source conductive layer is deposited to electrically contact the source region as a gate conductive layer is deposited atop the gate oxide layer.  The trench sidewall is profile tailored using a novel O2-SF6 plasma etch technique.  An oxide sidewall spacer is formed on the sides of the pattern definer and gate oxide structures, before depositing the conductive material.  A planarizing layer is applied and used as a mask for selectively removing any conductive material deposited atop the oxide spacer.  The polysilicon layer on the oxide is reduced in thickness during trenching so that any conductive material deposited atop the spacers protrude upward for easy removal of excess, conductive material.  The sidewall spacers can be sized, either alone or in combination with profile tailoring of the trench, to control source-region width (i.e., parasitic pinched base width) and proximity of the source conductor to the FET channel.  Electrical contact between the source conductive layer and the source regions is enhanced by forming a low-resistivity layer between them.

Title: Method and apparatus for nodes in network to avoid shrinkage of an interframe gap
Inventor: KAUFMAN CHARLES W
IPC: H04J3/06

Granted: 1992-06-02
Abstract: ABSTRACT OF THE DISCLOSURE     An output controller in a repeater node for controlling data transfers in a data communication system in which each node is operated by an independent local clock.  Nodes will occasionally delete idle bytes from a preamble to recenter an elasticity buffer.  The output controller performs a process that requires the elasticity buffer to be progressively more full before deleting another idle byte from the preamble.  Tranmission of the start of a subsequent frame is delayed and additional idle bytes are transmitted when the number of idle bytes being transmitted is at or below a certain threshold.  Multiple thresholds are uti-lized so that the amount of the delay can be adjusted.

Abstract: In a digital radio telephone transmitter an output pulse with e.g. cos<2>-shaped edges is produced by a voltage controlled power amplifier (1). When known control loop circuitry is used, the power (Pout) of the output pulse will rise almost step-wise at the beginning of the pulse, which leads to the spreading of the spectrum and to rise time delays of the output pulse with respect to the control pulse (TXC) at different power levels. According to the invention a good cos<2>-shape of the output pulse (Pout) and its tracking of the control pulse (TXC) almost without delay is achieved so that a squarewave pulse (Vp) is added to the control voltage (V2) of the power amplifier (1), the pulse (Vp) starting and ending substantially at the same time as the control pulse (TXC). In a preferred embodiment the squarewave pulse (Vp) is added to the control voltage (V2) only during that time when the control voltage (V2) is below that value, at which the the control loop begins to operate. <IMAGE>

Abstract: An improved method for the preparation of melamine by the conversion of urea and/or thermal decomposition products thereof. The urea and/or thermal decomposition products are converted to melamine in the presence of a gas mixture containing ammonia and carbon dioxide in a reaction zone containing a fluidized bed of catalytically active material. Melamine is desublimated from the melamine containing gas mixture in a desublimation zone by a dry-capture method leaving a desublimator off-gas mixture of ammonia, carbon dioxide and gaseous impurities. A major portion of this desublimator off-gas mixture is compressed and recirculated to the reaction zone as fluidizing gas for the bed of catalytically active material, without intervening treatment to remove gaseous impurities from the desublimator off-gas.

Abstract: In devices for mounting electrical devices, in particular switch, command or signal devices on a plate, like a bottom plate of a switch box or an assembly plate of a switch box or switch board of the type with at least one mounting bar for the devices disposed parallel to the plate as well as with two vertically-extending supports mounted on the plate for each mounting bar and with screw connections between the supports and the mounting bar, the difficulty exists that it is hard to reach the screw connections between the supports and the mounting bars, because of tight space conditions due to a tight arrangement of the devices relative to each other and due to the wiring which leads to the devices. In order to be able to obtain a simple servicing and safe support of the mounting bars on the supports, even at the tightest space conditions, it is proposed to provide screws which are disposed vertically with respect to the plate and which cooperate with clamping plates which are so designed that by tightening the screws, the supports are rigidly connected with the mounting bar due to the clamping effect.

Abstract: Packing container blanks for gable-top packages are cut out of a material web which, up to now, has caused an appreciable amount of waste material, since the edges of the blanks are irregular and cannot be "dovetailed" into one another. A packing container blank is provided with partly straight, parallel lateral edges (11,12), and partly transverse edges (11,12) which are indented according to a regular pattern which is repeated over the width of the blank. As a result of the indentations, the edges of the blanks too can be formed without wastage.
