Patent CA-2117526-A1 (CA)
Title: Magnetically actuated fluid motor
Inventor: GROUT EDWARD C
IPC: F04B9/105
Filed: 1993-04-07
Abstract: A magnetically actuated fluid motor has a shiftable member (94) having valve members for alternately closing one and opening the other of the large (44) and smaller face (46) of a stepped piston (42) reciprocating in a housing (12), the shiftable member carrying a magnet (100) and being shiftable to collocate the magnet with one of spaced apart magnet attractors (102, 104). When the magnet is collocated with a magnetic attractor, the magnetic holding force exceeds simultaneous resilient force supplied by spring members (105, 107) operating on the shiftable member. Stored energy in the compressed springs is released to shift the shiftable member only after the magnetic holding force is weakened by application of a separating force applied through stops which arrest the shiftable member while the piston continues to move without immediately opening the closed face of the piston.
Patent CA-2118081-A1 (CA)
Inventor: SWANEPOEL JACOBUS
IPC: C07C17/007
Filed: 1994-10-13
Abstract: The invention provides a method and installation for the production of a desired fluorocarbon compound, which includes the steps of providing a high temperature zone; and feeding at least one input material into the high temperature zone to generate a body of hot gas including fluorine-containing species and carbon-containing species. The molar C:F ratio in the body of hot gas is controlled at a selected value between about 0,4 and 2; and the specific enthalpy of the body of hot gas is controlled between about 1kWh/kg and about 10kWh/kg for a time interval, so that a reactive thermal gaseous mixture forms, containing reactive species including reactive fluorine-containing precursors and reactive carbon-containing precursors. Thereafter the reactive thermal mixture is cooled at a cooling rate and to a cooling temperature selected to produce an end product including the desired fluorocarbon compound. The input material is typically a C1-C10 perfluorinated carbon compound of the general formula C n F m in which 0 < n <= 10, and m = 2n, 2n + 2, or 2n -2 where n > 1, for example a gaseous fluorocarbon such as tetrafluoromethane (CF4).
Patent CA-2123126-A1 (CA)
Title: Health monitoring
Inventor: MAGILL ALAN R
IPC: A41D1/00
Filed: 1992-11-09
Abstract: Physiological monitoring of a baby is carried out from a fabric patch (2) that is attached by fibre hook-and-eye fastening to the ba-by's conventional, stretchable vest (1). The laminated patch (2), which bridges the baby's thoracic and abdominal regions, includes a con-cealed substrate (4) that carries piezo-electric film strips (10, 11) which sense, in those regions respectively, elastic deflections of the vest (1) caused by the baby's respiratory and heart functions. Signals from the strips (10, 11), together with a body-temperature signal from a thermistor (17, Figure 4), are processed and transmitted via an in-ductive-loop antenna (19) of the patch (2), to a remote unit (21, Figure 5) for further, more detailed processing to derive representation inter alia of thoracic-abdominal synchrony/asynchrony. The result is stored and monitored against stored clinical-data for display and alarm operation; the stored data is accessed by a data logger (31, Fi-gure 5) for detailed analysis. Patch-attachment can be under a flap (43, Figure 6) bridging an opening (44) in the vest (41), or may be in-ternally, rather than externally, of the vest.

Title: Skirt for an air cushion vehicle and filament member thereto
Inventor: QVIST LEIF
IPC: B60V1/16
Filed: 1992-12-08
Abstract: The air cushion chambers of an air cushion vehicle are horizontally delimited by a skirt. The skirt comprises brushes with elongated downwards extended filaments (9), which have downwards diminishing cross-sectional area thereby providing the brushes with sufficient stiffness to maintain the pressure in the air cushion chamber and such a large flexibility in the lower section of the skirt that ice can hardly deposit thereon. The filament members are mounted in a guide profile (2) in such a manner that above the members there is a chamber (12) for dispersion and conveying of deicing fluid which form the chamber (12) via a flow passage in every filament member may pass down into a clearspace (10) between the filaments (9). It is possible to design at least one of the filaments (109) with a forwards protruding web (115) on one of its sides and a backwards protruding web (116) on its other side. When mounted, the webs of the filaments may seize each other when the skirt is transversely deflected and thereby the webs lock the individual brush members to one another which provides the skirt with a larger stiffness in the transverse direction.

Title: Multi-frequency, multi-target, vehicular collision avoidance radar system using digital signal processing
Inventor: ASBURY JIMMIE R
IPC: G01S13/931
Filed: 1993-08-09
Abstract: A vehicular collision avoidance radar system using digital signal processing techniques including a transmit section that generates a two channel transmit frequency. An antenna both transmits the transmit signal and receives a reflected receive signal. A Schottky diode mixer generates a difference signal having a frequency equal to the transmit frequency minus the receive frequency. A signal switch in a front end electronics section time demultiplexes and samples the channel 1 and channel 2 signals. The samples are coupled to a two-channel analog to digital (A/D) converter. A digital electronics section receives the digital information and performs a Fast Fourier Transform (FFT) on each channel of digital data to determine relative speed and range of a target based upon the frequency and the difference in phase of the two channels. The digital electronics section also receives information regarding the status of vehicle operation and/or controls to determine the degree of danger presented by an identified target.

Title: Display structure
Inventor: DAIGLE DANIEL
IPC: G09F13/04
Filed: 1995-06-05
Abstract: A display structure for displaying a display sheet having information marked thereon. The display structure has a substantially concave frame formed by a back wall and a set of frontwardly extending peripheral walls. A peripheral border extends outwardly from the peripheral walls. The frame border is provided with a frame border channel formed therein. A photoluminescent component is adapted to be inserted into the frame border channel. The photoluminescent component is provided with a groove formed therein. The display sheet is adapted to be inserted into the groove formed in the photoluminescent component. A set of lighting tubes is positioned inside the chamber. A reflective sheet is positioned underneath the lighting means so as to reflect the light rays generated by the lighting tubes towards the rear surface of the display sheet. One of the main characteristics of the invention resides in that the configuration of the channel allows the light rays generated by the light source and reflected by the reflective sheet to flow simultaneously towards the back surface of the display sheet and the photoluminescent component. A single light source is thus used to illuminate both the back surface of the display sheet and to generate a photoluminescent reaction in the photoluminescent component which surrounds the display sheet and thus provides a visually attracting border.
