Patent CA-2231447-A1 (CA)
Title: Short code dialling
Inventor: CLAPTON ALAN JAMES
IPC: H04M3/38
Filed: 1997-03-26
Abstract: A mobile telephone network stores a list of short dialing codes in association with each user's identity so as to define the short codes which each individual user is permitted to use for providing access to a data conversion device PAD/PH1, which gives access to a private network PDN1. When a short code is dialed on a mobile station MS1, calling data comprising the short code together with caller identification data derived from the mobile station MS1 are transmitted over the radio link I to the mobile switching centre MSC1. Prior to routing the call, the identity of the dialing station MS1 is authenticated. The short code in the calling data is then compared with the permitted list of short codes to determine whether the user is permitted to make the call. If the caller is permitted to make the call, the call is routed to a destination corresponding to the data conversion device PAD/PH1. Thus, only permitted users may access the data conversion device PAD/PH1. Furthermore, it is possible for a network operator to configure the data conversion device (PAD/PH1) such that an operator can offer a subscriber a fixed relationship between a code and a data conversion device. The device can then be configured with subscriber-specific information so as to make onward communications easier and more professional, for example through personalised welcome pages, simplified access to user-specific data, etc.
Patent CA-2231643-A1 (CA)
Title: Reciprocating piston pump with bleed passages
Inventor: YOSHIMOTO CARLOS Y
IPC: F04B49/035
Filed: 1996-09-12
Abstract: A pump which has a piston (30) which is reciprocatingly moved inside a tubular housing (32) to extract fluid from the bottom of a well (29). The piston (30) is driven by motor (12) and has a horizontally extending base plate (50) with opening (52) provided with a plug/check valve (64). As the fluid is pumped, the plug (64) is raised and the fluid flows into a high pressure reservoir (35). When the pressure inside reservoir (35) exceeds a specified level, the base plate (50) is moved downward against an upward biasing force. This opens an annular port (51) exposing bleed ducts (56) and allows some fluid in reservoir (35) to flow back into low pressure chamber (37). Grooves (43) are also provided on the peripheral surface of base plate (50) for allowing small amounts of fluid to continuously escape from the reservoir (35) as long as pressure in the reservoir (35) is higher than in low pressure chamber (37).  This allows the pump to idle at start-up and starts the pump smoothly, as well as preventing overpressure conditions.
Patent CA-2233709-A1 (CA)
Title: Block coding for digital video transmission
Inventor: SHIN YESHIK
IPC: H04N7/52
Filed: 1996-10-01
Abstract: The transmission of digital video data is accomplished using a block coding scheme, which embeds timing and control signals into the data stream. The code is DC balanced, achieved by selectively inverting some data blocks, as a function of the cumulative disparity; and the transitions within each block are controlled, providing either a minimum number of transitions per block, or a maximum, and this is achieved by selectively inverting certain bits within a block. The use of low-swing differential transmission minimizes electromagnetic interference (EMI).

Abstract: A collapsible container (2) made from card, board or like stiff material has its openings closable by means of pairs of overlapping flaps (10, 12) projecting from the free borders of its side walls (4). In order to permit the flaps to be separated from each other, to permit the container to be flattened after having been emptied, and for the container to be reerected without the use of any additional material, such as adhesive tape, the respective surfaces of the flaps have secured to them flat two-component non-adhesive couplings (14, 16). Suitable couplings are those made from hooked- and looped-pile fabrics, such as those sold under the trademark Velcro.

Patent CA-2263614-A1 (CA)
Inventor: LECKHTMAN DAVID
IPC: B63B35/71
Filed: 1999-03-01
Abstract: The invention relates to dual hull kayak, with a one piece elongate moulded body of a continuous outer membrane enclosing an internal cavity. The kayak body has two lateral side walls and a concave bottom wall joined laterally with a bottom edge of each side wall to define two laterally spaced apart parallel pontoons each with a downwardly pointed keel. The top wall of the kayak body is joined laterally with a top edge of each side wall, to complete the hollow body. The top wall together with the bottom wall define a bridge platform spanning a central longitudinal tunnel between the pontoons. The pontoons support a top portion of the tunnel above the waterline. The top wall has a recessed open cockpit with a self-draining floor, side gunnels, and front and back cockpit walls formed into transverse reinforcing ribs. The simple easily moulded structure is very stable against lateral tipping, whereas conventional kayaks and canoes are very unstable laterally. The dual pointed hull also provides directional stability for straight line padding even by novices. Conventional kayaks or canoes are very difficult to master by novices who often paddle in a zig zig pattern and require a significant degree of skill to paddle in a relatively straight line. The sharp dual hulls reduce drag due to reduced wetted surface. The dual hull kayak is so stable laterally that it can be used as a diving platform and can be remounted by a swimmer from the water without tipping or overturning. Conventional kayaks or canoes require expert level skill to accomplish the same re-entry task. If desired the kayak can be inverted and the tunnel shape of the bottom wall provides a rigid water slide for children, water rescue cradle or can be adapted for use as a suntanning lounge. The kayak body includes bow eyelets and is rigid enough to be safely towed with a tow rope behind a motor boat.

Patent CA-2268716-A1 (CA)
Title: Inductor
Inventor: DICKINSON JOHN
IPC: H01F17/04
Filed: 1997-10-24
Abstract: This invention provides an inductor including an elongate conductor bar (10) of rectangular cross section, at least part of the bar being surrounded by a sleeve (20) which provides substantially no electrical conduction path through the sleeve in a direction away from the conductor bar. Such a sleeve (20) concentrates the lines of magnetic flux in the sleeve. The advantage of such an inductor is that at higher frequencies (e.g. above 100 Hz) the effect of the "skin effect" is reduced whilst at lower frequencies but high currents the stress on the inductor is also reduced.

Filed: 1999-04-21
Abstract: A milling apparatus is provided for grinding particulate material in a continuous flow process. A container is mounted on resilient pads for free movement thereon. A plurality of oscillators are mounted on the container for oscillating the container. The particulate material flows into the container through an inlet and passes through a plurality of grinding elements within the container which grind the material when they are agitated by the oscillatory motion of the container. A  grate mounted at an outlet of the container restricts the grinding elements from passing while permitting the particulate material to flow through. A motor is mounted on a fixed supporting surface for driving the oscillators. A pair of telescoping drive shafts having universal joints adjacent respective ends, connects the motor to the oscillators for isolating the motor from the oscillatory motion of the oscillators. The pattern of oscillation of the container is controlled by adjusting the relative orientation between the oscillators.

Title: High concentration no pulse delivery device
Inventor: BATHE DUNCAN P L
IPC: A61M16/20
Filed: 1999-05-17
Abstract: A respiratory therapy apparatus that delivers a predetermined pulsed dose of a therapeutic gas to a patient upon inhalation of the patient. The system has separate conduits for the supply of the therapeutic gas at a high concentration and for the supply of a diluent gas. The therapeutic gas conduit has a control valve that is accurately controlled to open and close so as to deliver a precise dose of the high concentration therapeutic gas. The diluent gas conduit has means to ensure there is a sufficient flow of diluent gas to ensure the said high concentration therapy gas is diluted to a safe concentration. A third conduit receives the gasses from both the first and second conduits to that the gasses are mixed together and administered to the patient. By this system, the therapeutic gas supply can be of a high, otherwise harmful, concentration and the therapeutic gas is diluted prior to introduction to the patient. The therapeutic gas may be nitric oxide and the diluent gas may be nitrogen or an oxygen containing gas.
