Title: Cabling machine
Inventor: NORTENIUS BENGT ARNE
IPC: G02B6/44
Filed: 1991-09-20
Granted: 2003-02-11
Abstract: The present invention relates to a cabling machine for laying optofibres, cables or the like in an oscillating, wavy path around a smooth pull-reliever or into grooves of oscillating, wavy shape extruded around a pull-reliever, so-called S/Z-cabling. The machine includes a pull-reliever reeling-off device, a braking capstan, a fibre reeling-off device or devices, an S/Z-bench for laying the fibre/fibres around the pull-reliever, a yarn spinner for fixating the fibre/fibres on the pull-reliever, and a wheel capstan and a taking-up device for forwardly pulling and taking-up the finished cable respectively, the S/Z-bench including a laying-on tube provided with a laying-on head, wherein the fibre/fibres pass over the laying-on tube and up to and through holes in the laying-on head, where they are laid on the pull-reliever and fixated with yarn taken from the yarn spinner located immediately downstream of the laying-on head. According to a first aspect of the invention, the S/Z-bench (6) includes an aligning mechanism (13) which grips around and guides the pull-reliever (2), and a motor (15) which imparts an oscillating, rotational movement to the aligning mechanism via a transmission (14). The laying-on tube (11) is fixed to or connected to the transmission (14) which imparts an oscillatory, rotational movement to the laying-on tube in a direction opposite to the aligning mechanism (13). A sensor (17) is connected to the transmission (14) and controls rotational movement of the motor (15) and therewith of the laying-on tube (11) and/or the aligning mechanism (13), wherein rotational movement of the laying-on tube is restricted so that the fibre/fi-bres (5) will only be wound onto the laying-on tube (11) to a small extent. According to another aspect of the invention, the pull-reliever reeling-off device (1) and the braking capstan (3) are rotatably mounted and the laying-on tube (11) is freely rotatable and guided by the action of laying the fibre/fibres (5) into the grooves in the pull-reliever (2). The laying-on tube (11) is connected to the transmission (14) and a sensor (17) is connected to the transmission and functions to detect rotation of the laying-on tube (11) caused by the oscillating waveshape of the grooves and causes the reeling-off device (1) and the braking capstan (3) to rotate to perform a correcting function and therewith counteract excessive rotation of the laying-on tube (11) so that the grooves in the pull-reliever (2) in the vicinity of the laying-on head will extend substantially rectilinearly and such that the fibre/fibres (5) extend substantially parallel with the laying-on tube.

Filed: 1992-07-31
Granted: 1997-02-25
Abstract: A process for creating segments out of an arbitrary string of handwritten alphanumeric script is described, in which the contours of the image are defined by the path a ball or pointer follows when allowed to roll from the top and bottom of an image, down or up either side. From the contours, the initial image cut points are determined. The pointer is provided with a capability to measure ink density in the nearby pixels. A grey scale threshold control is provided which operates in conjunction with the pointer as it rolls or moves, to define ink density above the threshold as a white pixel wherein no image content is present; and ink density below the threshold as a black pixel wherein image content is present.

Granted: 1999-12-21
Abstract: It is an object to provide a process for manufacturing galvannealed steel sheets having high anti-powdering property as required when they are press formed, and stabilized frictional properties in a coil. Steel sheets are plated in a bath having a low aluminum content, while they have, when entering the bath, a low temperature as defined in relation to the aluminum content of the bath, so that an alloying reaction may be prevented. Then, the sheets are heated for alloying in a high-frequency induction heating furnace so that the sheets leaving the furnace may have a temperature of from over 495°C to 520°C to yield galvannealed steel sheets consisting mainly of a ~1 phase. An iron or iron-alloy top coating having an appropriate iron content can be applied onto the plated steel surface to improve its paintability.

Title: Starch encapsulation of biologically active agents by a continuous process
Inventor: CARR MERLE E
IPC: A01N25/10
Filed: 1991-06-19
Granted: 1999-05-25
Abstract: Biologically active agents to be encapsulated are continuously blended with a starchy material and water, subjected to high-shear mechanical action at a temperature above the gelatinization temperature of starch, and continuously recovered as an insolubilized matrix of starch that entraps discontinuous domains of the agent. Alternatively, the core material to be encapsulated is added and blended with the aqueous dispersion of starch after the starch and water have been subjected to an elevated temperature sufficient to gelatinize the starch. Rate of release of agents to the environment can be controlled by preselecting a set of conditons related to various processing parameters. Encapsulation of biologically active compositions provides protection against degradative environmental conditions, improves safety in handling and slows the release of such compounds to the surrounding medium.
Patent CA-2090482-C (CA)
Title: Process for separating ilmenite
Inventor: WALPOLE ERNEST ALAN
IPC: B03C1/00
Filed: 1991-08-28
Granted: 1997-10-28
Abstract: A process for enhancing ilmenite from deposits of mineral sands or mineral concentrates comprises a single stage fluidised bed magnetising roast (16).  A temperature of 650°C - 900°C in an excess of a carbonaceous fuel (such as coal/char, CO or hydrocarbon) is used to provide an atmosphere in which the oxygen potential is controlled resulting in a consistently high magnetic susceptibility product.  Roasting has been used before but the current process requires a lower intensity magnetic separation stage (18) and provides improved recovery (even of tailings produced by prior art roasting process). Annealing (17) of the roasted product improves the resultant magnetic susceptibility.  Ilmenites having inclusions or selvedges of silicate minerals are further improved by employing a grinding step after magnetic separation prior to slagging or use as synthetic rutile feedstock. The roasting stage potentiates the ilmenite for leaching in the production of synthetic rutile.

Title: Remote charging cradle for cordless telephone handset
Inventor: YANKURA PETER JOHN
IPC: H04W88/02
Filed: 1993-06-10
Granted: 1996-11-12
Abstract: A remote charging cradle is configured for charging a cordless telephone handset unit and also permits the handset unit to receive and respond to a radiofrequency ringing signal while located in this cradle. While being charged, the handset unit looks for a ringing signal over a direct-current charging path provided through its battery charge contacts. The operation which permits charging of thehandset unit while also permitting the handset unit to receive a radio frequencyringing signal is achieved through a power cycling arrangement which controls the period over which the charging current from the cradle is applied to the handset unit. By applying this charging current periodically and then only for relatively short periods of time, the handset unit is able to sense the radio frequency ringing signal generated by an associated base unit during those periods when the charging current is not being applied and thereby respond to the ringing signal.

Abstract: Actuation of downhole tools is accomplished by inducing motion in the wireline. The downhole tool monitors such motion for predetermined patterns. Detection of a predetermined pattern actuates performance of a desired function. The pattern selected is sufficiently unique to avoid random or premature actuation. The tool may thus be actuated using ordinary nonconducting cable. In like fashion the tool can transmit stored information to the surface by a mechanical means such the resonant frequency of a mechanical signal in the cable.
