Title: Clothes dryer filter/humidifier
IPC: D06F58/22
Filed: 1990-09-07
Abstract: Abstract of the Disclosure An air filter and humidifier is attached to the back of a clothes dryer. Exhaust air is ducted from the clothes dryer exhaust port to the inlet port on the bottom of the filter/humidifier. From there, the exhaust air is directed upwardly through the filter/humidifier. A deflector redirects the exhaust air obliquely downward against the surface of water within a container. The water humidifies and filters the exhaust air. A variable amount of the conditioned air escapes through an adjustable vent lid into the home and the remainder is discharged through the filter/humidifier and ducted outdoors. A hinged or removable lid allows the user to remove the water container to add or replace water.

Title: Sensitizer for ferromagnetic markers used with electromagnetic article surveillance systems
Inventor: MONTEAN SAMUEL
IPC: G01V3/08
Filed: 1990-11-02
Abstract: Abstract of the Disclosure An apparatus for use with magnetically based electronic article surveillance systems employing certain types of markers includes a hollow core having a gap in its perimeter, a coil of wire wrapped around a portion of the core, and appropriate circuitry to drive the combination as an electromagnet.  The gap configuration produces an external field of large intensity but limited range, such that the magnetizable portion of a marker is magnetized without affecting magnetic states of the article to which the marker is affixed.  Depending on the nature of the circuit, the apparatus may be used as a desensitizer of such markers, or preferably as a resensitizer.          PF-FOR2.3

Patent CA-2038766-A1 (CA)
Title: Seal device
Inventor: FORSSBERG ALF
IPC: F16N39/00
Filed: 1991-03-21
Abstract: A Forssberg -3 A SEAL DEVICE          Abstract The invention concerns a method and a device for deminishing the over pressure that may occur in the oil housing if a seal leaks in a sumbersible machine such as a pump or a mixer.     A non-return valve (2) is arranged in the wall (1) of the oil housing and has its inlet (3) near the bottom of the oil housing and its outlet (4) outside the wall (1). Incoming water is heavier than the oil and thus assembles at the bottom. By arranging the inlet (3) and adjusting the opening pressure of the valve it is secured that only water will be diverted through the valve.

The control means is operated to drive the ram in such a way as to maintain substantially constant the speed of the suction cap 26 as it approaches a mushroom to be harvested, and to ensure the maximum energy of the moving parts of the picking head assembly is below 0.25 Joules, during that constant speed approach.t
Patent CA-2042396-A1 (CA)
Inventor: SCHNEIDER GEORG
IPC: G01L9/00
Filed: 1990-09-10
Abstract: The arrangement serves to process sensor signals which are furnished by a measuring sensor and by one or more further sensors. The measuring sensor generates a measuring effect which depends on a physical measured quantity to be determined and on physical disturbance quantities and each further sensor generates a measuring effect which depends substantially only on physical disturbance quantities. The arrangement includes a signal processing circuit which receives the measuring effects as input quantities. By analog processing of the sensor signals the signal processing circuit furnishes an output quantity, the ratio of which to a reference quantity in dependence upon the measuring effects forming the input quantities is governed by a transfer function defined in specific manner. The coefficients of the transfer function are adjustable for obtaining the desired transfer behaviour in dependence upon the properties of the measuring sensor, the influence of the disturbance quantities on the measuring effect of the measuring sensor thereby being compensated and errors in the relationship between the measured quantity and the measuring effect of the measuring sensor being corrected.

IPC: B21D7/025
Filed: 1991-08-15
Abstract: ABSTRACT OF THE DISCLOSURE      A frame member, as is used for office and other furniture, such as desks, chairs and other components, is formed from a length of rigid tubing, of polygonal cross-section, and bent on a diagonal.  The tube is bent by bending around an arcuate bending member having a peripheral groove which is a cross-section corresponding to about half the cross-section of the tube.  The tube is gripped against the periphery of the arcuate bending member, by a gripping member, the bending member and gripping member moving about an axis to bend the tube.  The tube is held in contact with the arcuate bending member by an elongate bending member which is slidingly supported on a fixed base and moves with the tube over the fixed base as bending progresses.  The tube is supported against collapse by a stationary internal non-deformable member.

Inventor: VAN OOIJ WIM J
IPC: C23C28/00
Filed: 1991-11-07
Abstract: Steel sheet coated with a nontoxic, relatively insoluble, inorganic, corrosion resistant coating. A silicate coating is formed on a steel sheet by rinsing the sheet for at least 30 seconds in an alkaline aqueous solution containing 0.005 M silicate, 0.005 M metal salt and having a temperature of at least 25ÀC. The sheet is dried to form an adherent silicate coating having a thickness of at least 2 nm prior to being treated with an aqueous solution containing 0.5-5 vol.-% silane. If the sheet is painted, the silane film forms an adherent bond between the paint and the silicate coating. A silane treated silicate coating minimizes red rusting on terne coated steel by sealing pin holes.  A silane treated silicate coating also provides good corrosion protection and paint adherence on cold-rolled or galvanized steel.

Title: Interferometer utilizing superfluorescent optical source
Inventor: FLING JOHN J
IPC: H01S3/07
Filed: 1990-08-30
Abstract: An improved broadband light source for a Sagnac interferometer includes a waveguide (110), such as a fluorescent optical fiber, that is pumped by a pump source (120) with a sufficient intensity to generate temporally incoherent light. The fluorescent optical fiber (110) has first and second ends, one end being an input end of the fiber (110). The broadband light is provided at an output of the fluorescent optical fiber (110) and is input to the interferometer. In order to prevent laser oscillations between the light source and the interferometer, one end of the fluorescent optical fiber (110) is formed so as to prevent reflections. The light output from the fluorescent fiber (110) to the interferometer comprises only that light that initially propagates toward the output of the optical fiber (110). In one embodiment of the light source the pump light from the pump source (120) is coupled into the fluorescent optical fiber (110) in a direction so that it travels away from the output of the fluorescent optical fiber (110) towards that first end. In an alternative embodiment, the fluorescent optical fiber (110) is a doubly clad optical fiber having a first accept-ance region and a second acceptance region at the first end. The pump light is introduced into an aperture window between the two acceptance regions so that the pump light can be introduced into the first end at an angle without requiring a reflective sur-face at the first end.
