Patent CA-2098386-A1 (CA)
Title: Regulateur de temperature pour materiel de brasage et de debrasage
Inventor: FISCHER THOMAS
IPC: B23K3/03
Filed: 1991-11-06
Abstract: Dans un régulateur de la température d'appareils à souder et à dessouder ayant un dispositif de chauffage alimenté par une source réglable de courant électrique de chauffage dont la puissance de chauffage est transmise à un point à souder par un dispositif de transmission de la puissance de chauffage, un signal proportionnel à la température du dispositif de chauffage est généré et comparé dans un comparateur d'un circuit de commande avec une valeur de consigne. Le circuit de commande dérive du signal de la sortie du comparateur un signal de commande de la source de courant de chauffage. En outre, un capteur (5) de la température est agencé dans la zone adjacente au point à souder du dispositif (3) de transmission de la puissance de chauffage, dont le signal de sortie est comparé dans un autre comparateur (23) d'un autre circuit de commande (23, 27, 28) avec une autre valeur de consigne (7). Le deuxième circuit de commande génère un signal de commande supplémentaire de la source de courant de chauffage (11). Les signaux de commande du premier circuit de commande (13, 17, 18) sont transmis à une première entrée d'un élément logique ET (20) et les signaux de commande du deuxième circuit de commande (23, 27, 28) sont transmis à la deuxième entrée de l'élément logique ET(20), dont le signal de la sortie ne déclenche la source réglable (11) de courant de chauffage que lorsque les deux circuits de commande génèrent en même temps des signaux de sortie correspondant à des températures inférieures aux valeurs de consigne respectives.

Title: Intra-frame filter for video compression systems
Inventor: NAIMPALLY SAIPRASAD V
IPC: H04N7/30
Filed: 1993-07-07
Abstract: ABSTRACT           A video signal encoder uses an encoding system such as that developed by the Moving Picture Experts group (MPEG).  A key component of this encoding system reduces the number of bits required to encode the video signal.  Apparatus according to the present invention, filters out high diagonal frequencies in the spatial domain of a video signal.  Specifically, two dimensional (2-D) filtering is performed on frames of a video signal to filter out high diagonal spatial frequencies before the video signal is separated into blocks.  These blocks may be encoded in fewer bits due to elimination of noise components and other image components having high diagonal frequencies.
Patent CA-2103705-A1 (CA)
Inventor: OMMAYA AYUB K
IPC: A61M1/36
Filed: 1992-02-07
Abstract: The present invention concerns a spinal fluid driven artificial organ device and methods for its use. The device (10) has a tripartite chamber with three sections. A micropore filter (B) separates chamber section (I) from chamber section (2) and a micro-pore filter (c) separates chamber section (2) from chamber section (3). CSF enters chamber section (I) via an inlet tube (T1) and an one way valve (V1). Micropore filter (B) allows entry of CSF into chamber section (2) but does not allow exit of any cells from chamber section (2) into chamber section (1). Micropore filter (c) allows free passage of CSF from chamber section (2) into cham-ber section (3) and prevents any cells in chamber section (2) from entering chamber section (3). The CSF flow exits chamber sec-tion (3) via an one way valve (V2) an an outlet tube (T2). The outlet tube (T2) delivers the CSF to the desired location.

Title: Railway Cab Signal Transmitter
Inventor: EHRLICH ANTHONY G
IPC: B61L3/24
Filed: 1993-09-21
Abstract: A transmitter for transmitting cab signal and track signal currents to a pair of rails includes the circuitry for mitigating runby currents which are not fully shunted by the rail vehicle.  High runby currents at the leaving end of a block are reduced by sensing the presence of a railway vehicle in the leaving end of the block.  In response to sensing the rail vehicle the cab signal voltage is reduced to a lower level.  The lower level and the position at which the railway vehicle is sensed are adjusted so as to permit a lead vehicle to receive at least a minimum cab signal value throughout its journey while assuring that following trains receive less than the minimum cab value required to activate the vehicle based receiver.  The train is sensed by the voltage drop across the rails as the train approaches.  A relay is used to respond to the presence of the train by applying a lower cab signal to the rails.

Title: Cleaning tool having split manifold
Inventor: SELEWSKI STEVEN R
IPC: A47L9/04
Filed: 1994-10-13
Abstract: ABSTRACT OF THE DISCLOSURE For a vacuum cleaning unit, a cleaning tool employing a rotatably driven brush and having a split manifold therein which allows  a  vacuum  airflow  to  be  directed  to  the  outermost longitudinal ends of the brush without interference with a drive belt rotatably driving the brush at its approximate longitudinal midpoint.  The cleaning tool includes an upper housing having a centrally disposed cut-out portion and a semi-circular portion for partially housing the brush therein.  A cut-out is formed in a base portion of the upper housing.  A lower housing also has a cut-out shaped identically to that of the cut-out portion of the upper housing.   A front sole plate is included which is secured to the lower housing and which includes a pair of openings separated by a central portion, where the openings allow portions of the brush to protrude.  Each of the upper and lower housings further have runner portions which form airflow channels through which a vacuum airflow may be generated.  When the upper and lower housings are secured together, a drive belt is able to extend through the centrally disposed cut-out portion,  the cut-out portion in the base of the upper housing and the cut-out portion in the lower housing to engage at its approximate longitudinal mid-point.  The apparatus thus allows a brush to be rotatably driven from its approximate longitudinal mid point while providing an increased vacuum airflow to the outermost end portions  of the  brush.    In  an  alternative  embodiment,  a snappingly engageable front sole plate is provided which allows quick and easy access to the interior of the cleaning tool with the need to remove threaded fasteners or the like, or the need for any external tools.

Title: Total Knee Endoprosthesis with Fixed Flexion-Extension Axis of Rotation
Inventor: HOLLISTER ANNE
IPC: A61F2/38
Filed: 1991-11-12
Abstract: The invention is a total knee endoprosthesis with a fixed flexion-extension axis (FE) throughout all degrees of flexion and extension of the knee. The endoprosthesis has a femoral component (20) with spaced apart medial and lateral condyle portions (21, 22) which slidably seat on a tibial implant portion (24). The fixed flexion-extension axis (FE) is directed inferiorly and posteriorly from the medial condyle portion (21) to the lateral condyle portion (22) and is offset from both the transverse and coronal planes equally by 3.0 to 3.8 degrees. A longitudinal axis (LR) through the tibia (3) allows the tibia (3) to rotate nonorthogonally and anteriorly of the flexion-extension axis (FE). A patellar groove (23) is perpendicular to the flexion-extension axis (FE). In the patellar groove (23) slides an optional patellar component (30) or the natural patella (36).
Patent CA-2122578-A1 (CA)
Title: Cab assembly
Inventor: NELSON PETER M
IPC: B62D25/08
Filed: 1993-08-26
Abstract: Cab assemblies utilized on modern day construction vehicles normally include a myriad of sheet metal components that are welded or bolted together to provide the structural support and the mountings for the various components that comprise a cab. The number of components and the time required to fabricate and weld, or otherwise assemble them, is often quite extensive. The more piece-parts that are required in the configuration of a cab, the more time is required to complete the assembly process. This translates directly into the cost of a cab assembly. The present invention provides a cab assembly (10) that utilizes a non-metallic floor member (50) as an integral part of its structure. The floor member (50) not only incorporates the hardware required for mounting various components housed within the cab assembly (10), it also provides support for the cab's windshield assembly. The windshield assembly is mounted between the floor member (50) and a structural member (34) positioned in the vicinity of the cab's roof. Both structural members are adapted to provide surfaces (40, 42, 44, 62, 64, 66) to which the windshield assembly (76) may be bonded. The combined result of these features provides a cab assembly (10) that has a greatly reduced number of components and is therefore extremely economical and efficient in its design.
