Abstract: A floor track system is provided to route utilities to workstations in open office plans, and the like.  The floor track system includes a plurality of individual floor track segments, each of which has a hollow interior in which the utilities are housed and isolated.          Each floor track segment also includes feet which indepen-dently support the track segment on the floor in a generally upright orientation, and an exterior shape which physically mates with the furniture units in the workstation, without supporting the same.  Opposite ends of the floor track segments are detachably interconnected in a predetermined configuration to form a continuous, self-contained and self-supported utility raceway that is physically separate from the furniture units, yet dimensionally cooperates and blends in with them.  Utility taps can be located throughout the floor track system to provide utilities to each of the workstations as required.

Title: Apparatus and method for spraying moving substrates
Inventor: STEWART WILLIAM H JR
IPC: D06B1/02
Filed: 1990-02-09
Abstract: Abstract Of The Disclosure A method and apparatus for dyeing a substrate using an array of spray generators.  In a preferred embodiment, each spray generator is comprised of a gas port from which an intermittent jet of pressurized gas is directed onto the substrate to be dyed.  Positioned along the path of the gas jet is a nozzle from which continuously flows a liquid dye.  When dyeing is desired, i.e., in response to pattern data, the gas jet is rapidly cycled on and off, thereby atomizing the dye emerging from the nozzle and establishing discrete bursts of spray which meter a controlled quantity of dye onto the substrate.  When the gas jet is interrupted, the nozzle projects an interrupted stream of liquid dye which does not contact the substrate.

Abstract: A zeolite catalyst composition is provided in which a first or upstream zone of the catalyst has a lower metal (e.g., iron or copper) promoter loading than the metal pro-moter loading of the second or downstream zone of the cat-alyst.  The first zone may contain from none up to about 1 percent by weight of the promoter and the second zone may contain from about 1 to 30 percent by weight promoter.  The zeolite may be any suitable zeolite, especially one having a silica-to-alumina ratio of about 10 or more, and a kinetic pore size of about 7 to about 8 Angstroms with such pores being interconnected in all three crystallographic dimen-sions.  The method of the invention provides for passing a gaseous stream containing oxygen, nitrogen oxides and ammo-nia sequentially through first and second catalysts as de-scribed above, the first catalyst favoring reduction of nitrogen oxides and the second catalyst favoring the oxi-dation or other decomposition of excess ammonia.
Patent CA-2012671-A1 (CA)
Title: Anti-noise circuits
Inventor: ROGERS ALAN C
IPC: H03K19/0175
Filed: 1990-03-21
Abstract: ANTI-NOISE CIRCUITS            Abstract Low noise circuits for single stage and multi-stage circuits reduce power rail noise, including both ground noise and supply noise caused by output power rail ground lead and supply lead inductance.  Anti-bounce circuits reduce ground bounce by suppressing turn on of the output stage pulldown transistor element during transient occurrence of ground bounce events.  Similarly anti-droop circuits reduce output supply Vcc droop by suppressing turn on of the output stage pulldown transistor element during transient occurrence of Vcc droop events.  Anti-undershoot circuits dissipate ground undershoot energy by establishing a transient sacrificial current flow through the parasitic output ground tank circuit following transition from high to low potential at the output and by prolonging the sacrificial current flow during transient occurrence of ground undershoot events.  Similarly anti-overshoot circuits dissipate overshoot energy in the parasitic output supply tank circuit by establishing a sacrificial current flow during transient occurrence of Vcc overshoot events.  Ground noise and power noise detectors are used for detecting occurrence of bounce, droop, undershoot and overshoot for actuating and enhancing operation of the low noise circuits.  The power rail noise detectors and anti-noise circuits are combined in various combinations and permutations.

Title: Apparatus and method for encoding telephone ringing signals
IPC: H04M19/02
Filed: 1990-08-22
Abstract: Abstract of the Disclosure A telephone signaling apparatus (108, 109) and method provides pleasant and quickly distinguishable call destination information and call origin information signals within the same audible ringing pattern (301). The ring pattern is partitioned into two segments with the first segment (302) used to provide the call destination information and the second segment (310) used to provide the call origin information. Within the first segment, call destination information is encoded by time division multiplexing different audio frequencies into fixed subsegments interrelated as part of a melodic contour pattern. Within the second segment, call origin information is encoded by varying the number of occurrences of a single frequency audio signal pulse which is syncopated to the melodic contour pattern provided by the different audio frequencies in the first segment.

Title: Process and apparatus for the continuous production of absorbent bodies
Inventor: KRAEMER WOLFGANG
IPC: D04H13/00
Filed: 1990-01-03
Abstract: The invention relates to a process and an apparatus for the contiunuous production of absorbent bodies (30) from a web of fibre material (40) which is folded longitudinally several times in a folding station (A) and which is surrounded in a guide tube (86) with a sheathing band (82), the longitudinal edges of which are connected to one another by means of a closing device. The web of fibre material (30) is thereafter fed to a press station (C) which consists of pairs of press and smoothing rollers arranged in close succession and offset at 90° relative to one another. By means of these press rollers, the web of fibre material (130) is rolled down in steps to or below the final cross-section of the absorbent body (30), to form a fleece rod (240). Subsequently, the absorbent bodies (30) are pinched by means of pinching rollers (334, 338) in a severing station (D) and are thereby preformed at the front end and thereafter fed to a forming device, by means of which the front ends of the absorbent bodies (30) are equipped with a round dome and the rear ends of the absorbent bodies (30) with a depression as an insertion aid, when the absorbent body (30) is to be used as a tampon for feminine hygiene. The process and the apparatus allow the high-speed mass production of absorbent bodies which, whilst using less material, make it possible to achieve a higher stability or buckling resistance of the absorbent bodies.

IPC: H02P29/02
Filed: 1990-10-29
Abstract: A method and an apparatus for the control of an elevator a.c. or d.c. hoisting motor driven by a frequency converter unit, or by a rectifier unit, supplied by a three phase power source is disclosed. The voltage of the mains power source is monitored using a voltage measuring unit. The frequency converter or rectifier is supervised by a control unit which selects a speed reference curve, best suited for a run. The controller unit allows the elevator speed to be varied continuously with the mains voltage so that the elevator always travels at the highest possible speed.  When an undervoltage condition is detected in the mains power source, the rotational speed  of the hoisting motor is reduced without modifying the acceleration so as to  avoid  an overcurrent  in the rectifier or  inverter switches. If, in addition, the acceleration is decreased before the maximum speed is obtained,  a higher maximum speed may be obtained for a given low level of supply voltage. The solution offered by this invention  enables the elevator system to work at undervoltages as low as 60%.
