Abstract: A multiple dosage feeder for a cage is provided.  The multiple dosage feeder includes a frame having a cage-interior side, a food holding member rotatably mounted on the frame, and a food presentation member disposed on the cage-interior side of the frame.  The food holding member holds a plurality of measured dosages of food or other substances, and at least a portion of the food holding member extends to the cage-interior side of the frame.  The food presentation member permits access to a single dosage of the plurality of dosages by an animal within the cage.  At least a portion of the food holding member is rotatable within the food presentation member so as to expose the single dosage of the plurality of dosages, while the food presentation member prevents access to any remaining dosages on the cage-interior side of the frame.

Title: Sound activated transmitter
Inventor: PALEY GARY
IPC: G08B1/08
Filed: 1996-05-06
Abstract: A remote annunciator system as shown in the figure in which the emission of an acoustic signal by a first annunciator (1) is detected by an acoustic signal detector (5) which causes a radio frequency transmitter (11) to transmit a radio frequency signal. A radio frequency receiver (15, 16) which receives the signal operates a second annunciator (23, 24) which is remote from the first annunciator, to cause the second annunciator to emit an audible or visual signal. Preferably, the radio frequency signal is encoded and is decoded at the receiver, and if the first annunciator can emit two different acoustic signals, the transmitted signal is encoded dependent upon which acoustic signal is emitted and the receiver decoder causes the second annunciator to emit an audible signal or a visual signal which depends on the transmitted signal encoding.

Title: Catheter securement device
Inventor: BIERMAN STEVEN F
IPC: A61M25/02
Filed: 1996-08-07
Abstract: An anchoring system includes a simply-structured suture-like device which permits a fluid tube or similar medical article to be easily attached to the patient without the use of needles and without suturing anything to the patient. The anchoring device desirably includes two threads or filaments and two corresponding receptacles. The filaments include protuberances which cooperate with apertures of the receptacles to permit easy insertion of the distal ends of the filaments into the receptacles, but inhibit retraction of the filament distal ends from the receptacles. A health care provider simply wraps the filament around the fluid tube or threads the filament through a suture hole in the medical article, and then threads the distal end of the filament through the receptacle aperture until the filament holds the medical article tightly against an anchor pad of the anchoring system. The anchor pad in turn includes an adhesive bottom surface which can be attached to the patient's skin.

Inventor: GIBSON JEREMY H
IPC: A47J19/06
Filed: 1998-02-25
Abstract: A garlic press is described which utilizes a unique grater plate comprising a plurality of spaced apart drain holes and a plurality of conical projections. A corresponding press plate contains numerous recesses to receive the projections to facilitate the pressing of the garlic by penetrating the skin of the garlic clove. The garlic press may use a clean-out tool which includes a plurality of clean-out pins for engaging the drain holes in the grater plate. The tool can be stored by clipping it to one of the handles or the press when not in use. The pins of the clean out tool are a fixed length between three in four times of thickness of the grater plate. Alternatively, the clean out tool can be affixed to the press unit opposite the press plate with the top presser unit rotated about 270 degrees from a closed position to a fully open position, allowing the clean out pins to enter through the drain holes. In this alternative, the length of the pins are preferably graduated with the pins close to the pivot being shorter and pins furthest from the pivot being longer for more effective cleaning.

Title: Speed control device for dc motors
Inventor: REBOLD JEROME I
IPC: H02P5/00
Filed: 1998-03-31
Abstract: A speed control device is provided such that the speed of DC motors is controlled to remain constant with varying voltages supplied from a power source. A given application for such a speed control device is in the use of portable, hand-held Metal Inert Gas (MIG) welders. The power requirements of a portable MIG welder are twofold. Power is required for the generation of a welding current to enable the workpieces to be sufficiently heated and thus, welded together, and power is also required to drive a wire spooler which provides wire at a constant rate, leading to accurate and consistent welds. The speed control device provided ensures constant power delivery for both powerrequirements, regardless of variations in the voltage of a power supply and irrespective of a mechanical load asserted on the welder.
Patent CA-2238150-A1 (CA)
Inventor: ECARNOT ERIC
IPC: F16F9/34
Filed: 1998-05-21
Abstract: A gas spring comprising a cylindrical body in which a main piston is slidable and carries a piston rod extending in sealed manner outwardly of the cylinder.   The main piston includes a bore connecting with a labyrinthine passageway.  The interior of the cylinder contains a fluid comprising gas under pressure and (optionally) some oil.  The gas urges the piston rod outwardly of the cylinder.  During the corresponding travel of the piston, the fluid transfers from one side of the piston to the other in a controlled manner through the bore and the passageway to allow relatively rapid travel.   However, when the main piston comes into contact with a second piston, freely slidable on the piston rod and biassed towards the main piston by a compression spring, this contact closes off the end of the fluid passageway, and fluid can now only transfer through the main piston by passing through a narrow radial channel,  thus reducing the speed of outward travel of the piston rod.  During this further outward travel,  the main piston drives the second piston towards an abutment against the force of the spring.

Title: Sps synchronization method
Inventor: ANAYA LUENGO JUAN JOSE
IPC: H04W92/00
Filed: 1998-06-30
Abstract: This invention refers to a synchronization method of a remote unit from a SPS timing signal (SPS) produced in a local unit. The SPS timing signal (SPS) is in the form of successive pulses (1) which are produced from signals received from satellites. The SPS signal (SPS) is asynchronous with respect to the system clock, that is, the reference clock defined between the local unit and the remote unit has no initial relationship with the SPS signal (SPS). The invention is characterized in that it includes the following steps: - calculation in the local unit of an information ("10011010") representing the number of local clock cycles occurring from the appearance of a pulse (1) until the moment (SL) when this information is injected into the data stream (FR); and - generation in the remote unit of a synchronization signal related to the SPS signal, depending on this information ("10011010").

Filed: 1997-02-20
Abstract: Procédé de traitement des anomalies occulaires de réfraction, notamment de la myopie, de l'hypermétropie et de l'astigmatisme, par décalage de la répartition spectrale de la lumière incidente. Des filtres optiques ou des teintes sont prévus sur les verres correcteurs, les verres de contact ou les implants intra-occulaires, ou bien au niveau des sources de lumière ambiante pour décaler la répartition spectrale de la lumière pénétrant l'oeil à traiter. Des sources de lumière ambiante émettant sous une répartition spectrale ou une plage de longueurs d'onde spécifique peuvent également être utilisées. On parvient, de cette manière, à maîtriser la répartition spectrale moyenne de la lumière visible incidente pour l'oeil, afin de traiter les anomalies occulaires de réfraction. Les modifications de la forme du globe occulaire et de la focalisation qui résultent de la réaction de l'oeil à la répartition spectrale de la lumière sont prévenues, atténuées, obviées ou même annulées. Les valeurs du spectre visible sont décalées vers des longueurs d'ondes plus courtes ou plus longues sur la totalité du champ de vision détecté par la rétine afin de traiter respectivement la myopie et l'hypermétropie. Pour corriger l'astigmatisme, la répartition spectrale de la lumière est décalée dans certaines zones du champ de vision de la rétine qui correspondent à une puissance anormale.
