Filed: 1990-06-08
Abstract: In a process for a passivating postrinsing of phosphate layers on metals before the application of a paint or adhesive, aqueous solutions are employed which have been adjusted to a pH value of 3 to 5 and which contain an aluminum fluorozirconate in which the Al:Zr:F mole ratio is (0.15 to 0.65):1:(5 to 7), and in which solutions the total concentration of Al + Zr + F is 0.1 to 2.0 g/l, preferably 0.2 to 0.8 g/l.  the postrinsing solutions may additionally contain at least one of the anions benzoate,  caprylate, ethyl hexoate, salicylate in a total concentration of 0.05 to 0.5 g/l and may preferably be adjusted to the required pH value with cations of volatile bases,  such as ammonium, ethanolammonium and di- and triethanolammonium.  The paint is subsequently applied suitably by cathodic electrocoating or powder coating or from a low-solvent high-solids paint.

Title: Photodegradation and heat-seal agents for matrix resins or plastics
Inventor: MARKOVICH RONALD P
IPC: C08L73/00
Filed: 1990-06-20
Abstract: ABSTRACT         A synergistic mixture of the anatase form of TiO2 and a CO-containing olefin (esp. ethylene) copolymer beneficially provides a means for enhancing and regulating the photodegradation rate of various matrix plastics and resins.  The mixture itself may be used directly for making some polymeric articles such as films, bags, packages,and the like or can be used as an additive (e.g. a masterbatch additive) for providing photodegradation to matrix polymers, plastics or resins. It can also include other additives which beneficially contribute to the regulation of the photodegradation rate, such as rutile TiO2 and/or other UV-sensitive or UV-absorbent or UV-stabilizing materials.         Furthermore, the presence of TiO2 and a CO-containing olefin (esp. ethylene) copolymer in another olefin polymer or copolymer beneficially provides a wider heat seal temperature range for the other polymer. For this heat seal temperature range effect, any of the TiO2 varieties may be used if they have acid surfaces.     36,159A-F

Title: Powers transmission
Inventor: LONNEMO KURT R
IPC: F15B13/02
Filed: 1990-07-25
Abstract: POWER TRANSMISSION                 Abstract of the Disclosure A hydraulic control system comprising a hydraulic actuator having opposed openings adapted to alternately function as inlets and outlets for moving an element of the actuator in opposite directions, a pump for supplying fluid to the actuator.    A meter-in valve individual to each opening is provided to which fluid from the pump is supplied and a pair of lines extending from the respective meter-in valves to the respective openings of the actuator.  A controller alternately supplies pressure to the respective meter-in valves for controlling the direction of movement of the load.  A second pair of lines extends from the first pair of lines to tank and a variable pressure relief valve is positioned in each line of the second pair of lines.          When the controller is moved to actuate one of the meter-in valves for supplying fluid to one of the openings of the actuator, the controller also actuates the variable relief valve associated with the line of the first pair of lines extending from the other of the openings of actuator to control the flow out of the other opening.  The controller thus simultaneously controls the fluid flow to the actuator and the fluid flow from the actuator, thereby simultaneously controlling the driving and braking functions of the system.

Title: Damped cradle for saw device
Inventor: GRELLMANN HEINZ E
IPC: H03H9/05
Filed: 1990-10-11
Abstract: Abstract of the Disclosure A damped cradle for a pressure sensitive device is constructed in a unitary form.  The cradle has a base that is attached to a substrate.  Extending upward from the base are side arms with pairs of spring, or compliant, tips that contact the sides of the pressure sensitive device.  Also extending upward from the base over the top of the pressure sensitive device are spring arms with compliant tips that contact the top surface of the pressure sensitive device in non-active areas.  Vibrational forces in lateral (X-Y plane) directions are damped by friction between the bottom of the pressure sensitive device and the surface of the substrate, and vibration motion in the vertical, or Z, direction is stopped by enough spring force to overcome the maximum acceleration force the crystal mass encompasses for a given application.  The spring forces of the spring tips and spring arms are balanced to produce a near zero pressure on the pressure sensitive device in both static and dynamic modes.

Title: Wood pole decay detector
Inventor: HANRAHAN ROBERT C
IPC: G01N23/18
Filed: 1991-03-08
Abstract: A manually operable device for detecting wood pole decay and a method of using the same are disclosed.  A gamma ray emitter is provided with guide means enabling it to be piloted longitudinally along the wooden pole so that gamma rays from the emitter pass diametrically through the wooden pole along a longitudinal axis of the pole.  The attenuation of the gamma rays are continuously recorded along the longitudinal axis, and a permanent record of the variation in gamma ray attenuation is made, from which it can be determined whether the pole is healthy or decayed, and if decayed, the location of the decay along the pole.  In order to facilitate locating decay in the pole, the guide means  includes  an odometer programmed to provide  an electrical pulse every 15cm which is recorded with the data of gamma ray attenuation.  Once data on gamma ray attenuation has been recorded along one longitudinal axis of the pole, the device may be used on a longitudinal axis at 90 to the first axis, in order to pinpoint the latitude and extent of decay points in the wooden pole.
Patent CA-2038549-A1 (CA)
Title: Electrically timer operated dish dryer
Inventor: EDWARDS TONY G
IPC: F26B19/00
Filed: 1991-03-18
Abstract: ABSTRACT     The Dish Dryer appliance comprises a dish receiving enclosed area with an open and closable spring-loaded hinged lid at the top for the purpose of drying the dishes. The Dish Dryer contains an electric timer button positioned on a back panel on the top which controls an electric heating unit consisting of an electric heating element positioned behind an electric fan. Hot air created by the electric heating unit is forced at an inclined angle through an intake vent at the back of the enclosed area holding the dishes. This hot air flow creates a circular current of hot air inside the enclosed area, builds up hot air pressure in the enclosed area, heats up the dishes in the enclosed area, evaporates some of the water on the dishes, forces most of the water off the dishes, and escapes with water through holes in the base of the enclosed area where it is directed containing more moisture and forcing by pressure and gravity most of the removed water back into the sink by means of an inclined drainer duct tray, at the base of the enclosed area. When the dishes have been heated to a safe temperature which takes several minutes, the timer shuts off the heating unit. Now, moist hot air escapes back through the intake vents as well as down through the escape holes in the base of the enclosed area, while less moist cooler air enters by the same means. Remaining heat contained in the dishes escapes out into the new air evaporating remaining moisture left on the dishes. This takes several more minutes and the timer then turns off an indicator light positioned on the panel at the top. The whole cycle takes approximately six minutes or less and because the last part of the cycle uses heat in the dishes as a source to dry them, the dishes are cooled down when cycle is complete and energy is saved.

Patent CA-2044563-A1 (CA)
Inventor: BLUNDY ROBERT F
IPC: B22D5/02
Filed: 1991-06-13
Abstract: An apparatus is provided for transferring articles from a pickup position to a pickoff position and thence to a dropoff position. The apparatus includes apair of pickup arms which are spaced apart to engage lugs oppositely extending from an article to be transferred. As the transfer arms are caused to be moved rotatably, the article is transferred to the pickoff position whereat the lugs are adjacent to stepped end portions of a pair of pickoff arms. Further movement of the transfer arms causes the article to engage surfaces of the stepped free ends of the pickoff arms and to be supported by engagement of the lugs with surfaces of the stepped end portions of the pickoff arms. Afterwards, the pickoff arms are turned to allow the article to descend until, at a predetermined position, the lugs of the article become engaged with a conveyor and become disengaged from the pickoff arms. Successive ones of the articles are supported by engagement of thelugs with the conveyor such that main body portions of the articles are submerged in a treating bath beneath the conveyor.
