Title: Rotary-tiltable car wash system
Inventor: MATHEWS W HARRY
IPC: B60S3/04
Filed: 1989-12-27
Abstract: A vehicle wash apparatus includes a reciprocating gantry-type framework with rotating fluid dispenser  along an upper extent thereof and at opposite sides thereof which are adapted to be rotated to deliver washing fluid at the vehicle as the apparatus traverses the length of the vehicle. A tilt mechanism is provided so that the rotating manifolds can be tilted at opposite ends of the vehicle to direct the cleaning fluid at the ends of the vehicle when the apparatus is positioned adjacent the ends of the vehicle.  A unique bearing seal element supports the rotating manifolds on a rotatably driven coupling from a motor so that liquid can be delivered to the rotating manifolds in a leak-free environment and over an extended life. An ultra-high molecular weight polyethylene material is utilized in bearing seal members in the element which serve both as a liquid seal and a bearing surface.

Title: Fin for a heat exchanger and heat exchanging system using the fin
Inventor: FUHRMANN ERNST
IPC: F28F1/32
Filed: 1990-03-23
Abstract: ABSTRACT OF THE DISCLOSURE         A heat conducting fin for a heat exchanger is provided with an array of deep drawn collars defining passages with flattened, oval cross-sections for receiving heat exchanging pipes of a corresponding cross-section.  In order to prevent the formation of cracks in the collars particularly when a large ratio of the maximum diameter to the minimum diameter of the oval collar involves very small radii of curvatures, the height of the collar in the region of its small radius of curvature is less than in the region of its large radius of curvature.  The invention also relates to a heat exchanger including a stack of such fins and a series of heat exchanging pipes passing through the passages in the collars and being attached to the inner walls of the collars by expanding corresponding pipe portions.
Patent CA-2018320-A1 (CA)
IPC: H01L31/10
Filed: 1990-06-05
Abstract: Abstract of the Disclosure In this invention, there is disclosed a new photodiode which comprises a semimetal/semiconductor junction.  Distortion of the bands associated with this type of junction result in current flow when an electron hole pair is formed by, for example, a photon impinging upon the junction.  The photodiode operates in the photovoltaic mode.  However, rather than relying on impurity doping to fabricate a p-n junction, the semimetallic nature of HgTe and its large conduction band offsets with Hg1-xCdx Te are used to create a rectifying Schottky like structure.

IPC: G05F1/10
Filed: 1990-07-30
Abstract: In order to automatically restore the normal switching position of a relay armature after an accidental external impact has switched it to the off position, the output of the relay is monitored and is applied to a differentiating circuit.  A compar-tor is provided to reflect on and off operations of a main switch.   In the event that the output of  the relay drops suddently, the differentiating circuit outputs a pulse to a wave-shaping circuit (e.g., a Schmitt trigger).  A gate circuit is supplied with the outputs of the wave-shaping circuit and the comparator.  The out- put of the gate circuit momentarily allows a relay driver to actuate the relay in response to the undesired change in relay status, and hence the relay armature resumes the on position.

Abstract: An atomizing dispenser utilizes a vertical hollow elongated body with an upper section defining a first hollow vertical cylinder and a lower section defining a second outer hollow vertical cylinder having a diameter smaller than that of the first cylinder and a third inner hollow vertical cylinder concentric with and spaced inwardly from the second cylinder. The lower ends of the second and third cylinders are joined together. The upper end of the third cylinder has an aperture. A hollow piston is vertically movable with the lower end of the piston slidably engaging the inner surface of the upper section of the body. A vertically movable vertical member has an upper section extending through the lower end of the piston into its interior, an enlarged integral middle section and a further enlarged integral lower section. The lower section defines a fourth vertical hollow cylinder, disposed between the second and third cylinders, having an open lower end and an inwardly extending horizontal shoulder at its upper end. Spring means disposed within the body bears against the joined lower ends and against said shoulder. A pump chamber defined by a hollow vertical region bounded by adjacent portions of the body, member and piston has a first port for fluid entry and a second port for fluid discharge. An actuator device is disposed above and engages the piston in a normal fully raised position at which both chamber ports are sealed and the spring means is in fully extended position. The device, when subjected to downward pressure, establishing a force which moves the piston and member downwardly with the piston and middle member section being disengaged, opening the second port, the first port being closed When the downward pressure is released, the piston and member are moved upwardly, the first port is opened and the second port is closed.

IPC: H04M3/00
Filed: 1990-12-19
Abstract: LINE INTERFACE CIRCUIT            Abstract of the Disclosure Alternating current signals are differentially coupled between a two wire communications line and a telecommunications facility by a line interface circuit.  The line interface circuit differentially drives signals destined for the two wire communications line, with a predetermined source impedance, via tip and ring amplifiers and tip and ring feed resistors.  An amplifier circuit differentially receives signal voltages being developed by currents traversing the tip and ring feed resistors, and detects signals destined for the telecommunications facility by subtracting a representation of the signals destined for the two wire communications from a representation of the differentially received signals.  A notch filter connected in series with the tip and ring feed resistors impedes any longitudinal signals of about a predetermined frequency which would otherwise traverse the tip and ring feed resistors, whereby a routinely available industry standard common mode rejection performance characteristic of a differential input of the amplifier circuit consistently yields telephony standard performance in the presence of reactively coupled longitudinal power line signals of about said predetermined frequency.                             -i-

Abstract: Cette invention concerne la synthèse de fréquence à l'aide d'un oscillateur commandé (20) incorporé dans une boucle à verrouillage de phase, où la fréquence du signal de sortie de l'oscillateur est divisée (22) périodiquement par deux entiers différents, de telle sorte que la fréquence est, en moyenne, divisée par une valeur qui est égale à un entier N plus ou moins une fraction numérique dont la valeur absolue est inférieure à 1. La position de phase des impulsions formées de cette façon est comparée à la position de phase des impulsions provenant d'un signal de référence (10, 12), de manière à obtenir un signal d'erreur de phase. Afin d'éliminer les variations périodiques d'un signal de commande d'oscillateur résultant d'un bruit de phase, on ajoute ou on retranche, de manière connue, au signal d'erreur de phase, une valeur de correction (24, 26) qui dépend de la fraction numérique précitée. Afin de supprimer la nécéssité de multiplier la valeur de correction par un facteur proportionnel à la valeur inverse de l'entier N, on amplifie plutôt le signal d'erreur de phase avec un facteur N (28) avant d'ajouter ou de soustraire la valeur de correction. La largeur de bande de la boucle est également maintenue constante de cette manière.

The outer wall is connected to the intermediate wall by a plurality of radially oriented, angularly separated outer load bearing struts of the main casting.  The outer struts are offset from the inner struts so that the portions of the intermediate wall between adjacent pairs of inner and outer struts define cantilever springs which accommodate relative thermal growth in the turbine support occasioned by temperature gradients to which the turbine support is exposed.
