Title: Drag conveyor system for particulate material
Inventor: BAKER JON F
IPC: B65G19/22
Filed: 1998-03-16
Abstract: A drag conveyor consists of a uniquely-configured trough and correspondingly-shaped outer edges of chain-driven paddles which enable the trough construction to provides physical support for a return run of the chain. The cross-sectional shape of the trough further restricts the paddles from tending toward lifting above the trough bottom and climbing or twisting as they carry material toward the outlet end of the conveyor. The paddle shape results in a self-cleaning conveyor, even enabling handling of materials heretofore not feasible with conventional U-shaped trough conveyors. Elimination of obstructing idler sprockets and cross shafts of the prior art enables a productivity increase of as much as 15% for the same designated size of conveyor.

Title: Method of and apparatus for coding audio signals
Inventor: SEITZER DIETER
IPC: G10L19/02
Filed: 1996-08-16
Abstract: In coding of an audio signal, coded signals with low quality and bit rate on the one hand and coded signals with high quality and bit rate on the other hand are transmitted to a decoder. At first, the audio signal is coded with low bit rate and is transmitted to the decoder before an additional coded signal is transmitted to the decoder, which either alone or together with the first coded signal upon decoding thereof provides a decoded signal with high quality within the decoder. In this manner, a low-quality decoded signal is generated first in the decoder before decoding of the high-quality signal is possible.

Inventor: HAMILTON THOMAS I
IPC: A47L5/18
Filed: 1998-09-23
Abstract: A portable, self-contained vacuum device designed for hand-held use to create a moderate vacuum effect for various applications. A small diameter tube (10) is firmly attached (14) to the nozzle or spray tip of an aerosol canister and inserted at a point (16) through the wall of, and directed in one direction along the interior length of, a larger diameter tube (12). The tubes may be fixed to the exterior of the aerosol canister, may be detachable for storage, or may be manufactured into the interior of the aerosol canister. When propellant gas from the aerosol canister is released and injected out of the outflow end (20) of the smaller diameter tube toward one end of the larger diameter tube, the resulting aspiration of ambient gasses creates a vacuum effect at the opposite end, or intake end (18), of said larger diameter tube. A vented receptacle (22) is added to capture the aspirated debris and other matter, but allow the propellant and ambient gasses to pass into the atmosphere through filter screens (28) of desired permeability. The use of antiseptic additives with the aerosol propellant provides enhancement for use of the device for biological waste collection purposes. The use of preservative additives with the aerosol propellant provides enhancement for use of the device for specimen collection purposes.

Patent CA-2250869-A1 (CA)
Title: Combination therapy for treatment of erectile dysfunction
Inventor: MAURICE DONALD H
IPC: A61K45/06
Filed: 1997-04-23
Abstract: In the field of treatment of erectile dysfunction there is disclosed a novel therapy in which the actions of an agent or agents, produce a combination of effects to induce effective erection (and avoid priapism) while reducing or entirely avoiding pain. The method taught combines a first action of an agent which is to antagonize a drug-induced pain stimulus within nociceptive nerves of penile tissue with a second action of either the same agent or of a second agent, which enhances, synergistically, smooth muscle relaxation. The synergism allows for at least an equivalent effect of smooth muscle relaxation to be obtained at significantly lower doses of a smooth muscle relaxing agent such as PGE1 which in standard therapy is also in 40-45 % of cases paininducing at doses which achieve effective erection. Thus, in an anatomical site where nociceptive tissue is in close proximity to one or more effector systems, the method enhances the effector system while reducing nociception in the nociceptive tissue which nociception would be caused by an agent such as PGE1 which is used to trigger the effector system.

Patent CA-2252198-A1 (CA)
Inventor: GRAY WILLIAM STEPHEN
IPC: A24F47/00
Filed: 1998-11-09
Abstract: Smoke Without A Trace Technology (S.W.A.T.T.) is a smoke management system that will allow an individual to smoke cigarettes in environments where smoking may cause irritation to others, or in environments which are not conducive to smoking.      This broad range of environments can include office buildings, lounges, restaurants, homes, malls, and even outdoors in rainy or windy conditions. A cigarette is placed within the device, thus enclosing it in a circular tube such that it is completely contained within the device. The cigarette can then be lit using an incorporated electronic butane lighter. Smoke is then inhaled by the user through a one-way valve, and can then be exhaled back into the device by means of a second one-way valve. The smoke is then forced through two separate filters (carbon and particle filters) by the exhalation of the user and with the aid of a small fan inside the device. At any given time throughout the smoking process, the cigarette can be extinguished by activating a mechanism within the device itself which creates an airtight seal around the cigarette compartment thus depriving the cigarette of the oxygen it requires in order to burn causing the cigarette to go out. The ashes are then collected in a small compartment below the cigarette compartment and can be removed by opening a small sliding panel. This eliminates all foul odor and dangerous toxins from the exhaled smoke thus proving the S.W.A.T.T. to effectively allow the user to smoke virtually anywhere.
Patent CA-2252276-A1 (CA)
Title: Winged agricultural implement with headlands control system
Inventor: MAYERLE DEAN JAY
IPC: A01B63/102
Filed: 1998-10-30
Abstract: A headlands control system for a winged agricultural implement includes a headlands actuator operatively connected between implement wing actuators for establishing operation in either of two modes. In the first mode, when the headland actuator is in a first position (e.g.extended), the wing actuators are provided extra downward range to pivot and bias the wing sections downward below horizontal as may occur during operation over uneven ground. In the second mode, when the headland actuator is in a second position (e.g. retracted) and the implement is raised (e.g. at the headlands), the downward range of the implement wings is more limited (as compared with the first mode) at the point where the wing actuators are fully extended. This system thus provides means for preventing implement wings from drooping in the headland position so the operator is not required to reset the wing control from float mode, or from down pressure mode, depending on what is equipped.

Title: A method for levelling and filling of ditches, and a device for use in levelling and filling ditches
Inventor: WIKER OMAR
IPC: E02B9/06
Filed: 1996-05-21
Abstract: A method for levelling and filling a ditch is described, where a levelled layer of fine material is provided together with a contiguous layer of coarse material. A box-shaped device is described, having a height-adjustable rear end (11) which when raised and lowered will determine the levelling height of the fine material which is in the box-shaped frame and exits therefrom below the raiseable and lowerable end wall when the box-shaped frame is moved through a ditch. Lateral projections (26, 27) on the end wall (11) bring about a simultaneous dispensing/apportioning of coarse material along the side of the levelled layer of fine material (3). Whilst the box-shaped frame is moved forward and dispenses the layer of fine material, the side projections (26, 27) will deal with the dispensing/levelling of coarse material thrown thereon. The box-shaped frame has a roof (16, 17) having crossfall, which will guide the coarse material down to the side. The roof (16, 17) can be opened to allow the box-shaped frame to be filled with fine material.
