Patent CA-2106589-A1 (CA)
Inventor: RUDICH GEORGE JR
IPC: G05B19/35
Filed: 1993-02-10
Abstract: A positioner (100) for use in pneumatic systems moves a pneumatic operator. The positioner is an electronic pilot position-er or eletronic to pneumatic interface which provides accurate positioning of linear actuators (250) in response to an electronic control signal (561). The actuator is moved as pneumatic fluid is exhausted or supplied through the exhaust valve and supply valve. The positioner utilizes two solenoids for controlling a supply valve (302) and an exhaust valve (312). The positioner in-cludes an electronic control circuit (500) which receives a signal from a central controller and a signal from a feedback circuit (200). The electronic control circuit compares the feedback signal and the controller signal and generates a signal for positioning the actuator.

Title: Valved discharge mechanism in a refrigerant compressor
Inventor: KIKUCHI YASUO
IPC: F25B31/00
Filed: 1993-09-21
Abstract: A refrigerant compressor includes a compressor housing defining a chamber in which successive strokes of intake, compression, and discharge of a refrigerant gas are repeatedly performed. The chamber is divided into a compression chamber and a discharge chamber by a valve plate. A discharge hole links the compression chamber to the discharge chamber. The valve plate includes an end surface which faces the discharge chamber. A discharge valve regulates a flow of the refrigerant gas from the compression chamber to the discharge chamber. A valve retainer limits the bending movement of the discharge valve in the direction in which the refrigerant gas exits the discharge hole. The valve retainer is secured to an axial end surface of the valve plate together with the discharge valve by a fixing bolt. The discharge valve bends as it opens and closes the discharge hole. The valve plate includes an annular groove formed at the end surface thereof. The annular groove surrounds the discharge hole and is entirely overlaid by the discharge valve. Also, an air gap may be formed between the discharge valve and the valve plate. Thereby, noise due to resonant vibration caused by the discharge valve can be effectively reduced or eliminated.

Title: Roof vent
Inventor: MACLEOD RICHARD J
IPC: E04D13/16
Filed: 1994-01-07
Abstract: ROOF VENT                   Abstract of the Disclosure A roof  vent comprising a one-piece plastic body including a base wall with air guiding vanes to ventilate the interior of a building.  A plurality of spaced intermediate transverse supports are provided along the central longitudinal axis of the plastic body. The intermediate supports are adapted to facilitate folding at the center of the vent to maintain a straight line bend and to provide support for the central portion of the vent to improve stiffness and appearance. Thus, the vent is prevented from sagging, bowing or collapsing due to the weight from snow buildup or due to impact of nailing the vent to the roof.  The supports overlap to accommodate different roof angles.  Additionally, the roof vent has a tongue and groove  arrangement  on  the  end walls  at  each end for  an interlocking connection to an adjacent roof vent. One embodiment of the roof vent is adapted for use on a hip roof.  In this embodiment, a separate wall is used to deflect entry of snow or rain.  The supports have notches to accommodate the separate wall.  Furthermore, drain openings are provided in the vanes and the end walls to allow moisture to escape and cross-walls are also provided to prevent moisture from flowing along the inside surface of the roof vent.

Inventor: LEPINE RENE
IPC: F24F7/06
Filed: 1994-06-28
Abstract: L'air chaud produit par les systèmes de chauffage conventionnels d'une maison, s'élève immédiatement au plafond parce qu'il est plus léger que l'air froid. Il en résulte une différence de température laissant l'air plus froid au niveau du plancher. Dans la présente invention, l'air chaud perdu au plafond est récupéré et retourné au niveau du plancher par un appareil comprenant un ventilateur électrique fixé à l'intérieur d'un boîtier suspendu près du plafond. Ce boîtier est entouré d'un conduit flexible descendant verticalement jusqu'au sol et comprenant une entrée et une sortie. Ce conduit se gonfle sous la légère pression du ventilateur et permet à l'air chaud de retourner au plancher et de se mélanger de façon continue à l'air froid pour obtenir une température égale et confortable dans la pièce, particulièrement au niveau des pieds. Le conduit flexible est changeable et remplaçable par un neuf lorsqu'il est usé et défraîchi. Le fil d'alimentation descend à l'intérieur ou à l'extérieur du conduit flexible et peut comprendre un sélecteur de vitesse intégré. Un élément épurateur d'air peut être installé dans la partie supérieure du boîtier cylindrique.

Filed: 1994-11-23
Abstract: A brush holder apparatus and method for biasing a brush outwardly of a brush box.   A brush box cover is slidingly disposed over an electrical cable along with a coil spring.          Next, a brush shunt is electrically secured to an end portion of the electrical cable by a crimp member.  The brush box cover is then slidably urged towards a brush secured at a terminal end of the brush shunt.  This causes the brush shunt to be folded so as to place it in general longitudinal alignment and parallel with the electrical cable.  The brush box cover is then further slid along the electrical cable, thus urging the spring over the brush shunt and into engagement with the brush electrically secured at the terminal (i.e., outer) end portion of the brush shunt.  The brush box cover is further slid along the electrical cable until the  crimp member and a portion  of the brush shunt become wedgingly engaged in a portion of the brush box cover, to thereby hold the spring in a compressed condition between the brush box cover and the brush.  Accordingly, there is no need to first compress the spring and hold the spring compressed while the brush shunt is attached to the electrical cable.  The apparatus and method significantly eases the manner in which a brush holder may be assembled.     .
