Abstract: Dosage form comprising, firstly, an outer envelope comprising gelatine and, secondly, an inner non-aqueous liquid or semi-liquid phase containing an active ingredient in a solution. The invention is characterized in that the active ingredient consists of a spermicide and the inner phase includes, in addition to the active ingredient: a major proportion of a lipophilic agent compatible with the rubber latex forming a condom; a minor proportion of at least one hydrodispersible agent; at least one bioadhesion agent; and at least one gelling agent for the lipophilic agent. Said vaginal dosage form combines the advantages associated with a soft capsule with spermicidal, antiseptic and lubricating properties. It can be used safely in conjunction with condoms without altering their rubber latex composition.

Title: Agricultural implement with down-force control
Inventor: HUNDEBY DAVID ROBERT
IPC: A01B63/14
Filed: 1997-07-11
Granted: 2005-06-07
Abstract: Down-force control is provided by a top-link, which presses down the rear end of a tool-bar carrying multiple rows of seeder tools. The height of the tool bar is set front and rear during operation. The top-link includes a hydraulic ram. The ram is supplied with pressure from a pressure-reducing-relieving valve, whereby the downward-force on the rear of the tool-bar remains constant during operation. The tool bar has side wings which are pressed down by a pressure that is regulated by the same valve. The system allows the seeder to maintain constant implantation depth, even over uneven ground.

Title: Translateral spinal implant
Inventor: MICHELSON GARY KARLIN
IPC: A61B17/70
Filed: 1996-06-06
Granted: 2007-09-04
Abstract: This invention is an oversized spinal implant (100) for trans-lateral insertion into the disc space between two vertebrae, a length that is greater than one half of the transverse width of the vertebrae, and is greater than the depth of the vertebrae. The trans-lateral implant of the present invention has a height that is greater than the height of the disc space between two adjacent vertebrae so as to engage both of the vertebrae.  The width of the implant need be only slightly less than the depth of the vertebrae themselves. The trans-lateral spinal fusion implant of the present invention has more surface area of contact, and thus permits greater stability so as to withstand torque, and in the case of a threaded implant, increases the depth in which any threads are able to penetrate the vertebrae.

Abstract: A mechanical lifting jack with a locking mechanism that arrests upward motion of the handle if the handle is suddenly released by the operator while raising or lowering a load. A latch on the pivot attachment of the handle to the lifting assembly is actuated by a lever disposed at the distal end of the handle, and engages into a toothed safety link when the lever is released. In the event that the operator suddenly releases the handle accidentally, the latch engages the safety link to arrest the upward motion of the handle. The invention can also be used to lock the handle into an upright position alongside the vertical support for compact storage.

Granted: 2007-02-13
Abstract: Containers are described for retention of human or animal remains for extend ed periods. The bags are constructed of laminated materials and sealed, which prevents the escape of noxious or odorous decomposition gases or harmful decomposition fluids into the ambient surroundings. The invention also provides for infusion or extraction of gases to retard the decomposition of the contained remains. The container is constructed of flexible multilayer laminated walls forming an interior chamber for accommodation of remains, and after the remains are emplaced the container's opening is sealed. The multilayer laminate includes at least two layers of polymeric sheet material with a metal foil layer between them, although use of more complex polymer/metal laminates is also described. The polymeric layer materials include polyolefin, nylon or polyvinyl sheet materials and the met al foils are normally aluminum foil. The containers may be furnished flat to the end user and joined in series coiled into large rolls from which the user merely cuts off desired lengths as needed. The roll structure and sealing method may also be used with other types of containment bags.

Patent CA-2275893-C (CA)
Title: Low false alarm rate video security system using object classification
Inventor: WALDMAN GARY S
IPC: G06T7/20
Filed: 1997-12-23
Granted: 2005-11-29
Abstract: A video detection system (10) and method detects an intruder from video images of a scene. The method employs a recognition process to differentiate between humans and animals. The method is used only after possible false alarms resulting from identified effects of noise, aliasing, non-intruder motion occuring within the scene, and effects of global or local lighting changes. The object recognition process includes determining the regions containing a potential intruder, outlining and growing those regions to encompass all of potential intruders, determining a set of shape features from the region and eliminating possible shadow effects, normalizing the set, and comparing the normalized set with sets of features of humans and animals. This comparison produces a confidence level indicating a human intruder. An alarm is given for a sufficiently high confidence level. The possibility of a false alarm due to an animal or a non-identifiable object is also substantially eliminated.

Granted: 2005-11-01
Abstract: Disclosed is a method for providing an improved cementitious product (56) which includes improved surface characteristics such as skid resistance, as well as improved structural characteristics such as flexural toughness. The product (56) is provided by the inclusion of skid-resistant particles within an uncured cement product, such that the product eventually cures with the skid-resistant particles fixed at, and adjacent to, the surface, providing improved skid resistance to the cement product and its supporting surface, which could be a pedestrian sidewalk, steps (54), a vehicle roadway, handicapped ramps, or other surfaces where skid resistance is required. The product (56) is desirably softer in structure than traditional concrete structures to allow for desirable wearing by traffic thereon to continuously expose new rubber particles, while still having integral properties which discourage pullout of the particles.

Abstract: A contact assembly (50) for an accumulation conveyor (10) includes a support member (60) having a cavity (72) dimensioned to receive a force producing device (74). A contact member (50) is positioned between the force producing device (74) and the conveying rollers (25) and reciprocates with respect to the conveying rollers (25). The contact member (50) includes a platform (80) which supports a pair of cantilevered contact rollers (84, 84', 86, 86') journaled at opposing ends of the platform (80). When the platform (80) is vertically reciprocated by the force-producing device (74), the contact rollers (84, 84', 86, 86') in driving engagement with a drive belt (30) are forced upward, placing the drive belt (30) into driving contact with the conveying rollers (25). The contact member (50) is rotatably connected to the support member (60) while the contact roller (84, 84', 86, 86') positioned first in the direction of travel of the drive belt is formed with a pair of flanges (85). Contact between the drive belt (30) and the flanges (85) rotates the contact member (50) to thereby maintain alignment of the contact rollers (84, 84', 86, 86') and the drive belt (30).

Title: Method of multichannel data compression
Inventor: PILIAVIN MICHAEL A
IPC: H04N19/103
Filed: 1999-08-19
Granted: 2007-05-22
Abstract: A method for compressing multiple channels using an MPEG-compatible technique (Fig. 10: block 96). The method encodes differences between frames within and among each channel (Fig. 10: blocks C1, C2, and CN). Some frames are predicted and some are skipped. Differences between the current and predicted frames for each channel are compared to a threshold E0 for each successive group of frames, after each group of each channel is encoded. If, for any of the groups of frames, the difference between the current and predicted frames of any of the channels reaches the threshold, the method inserts an I-frame into the sequence of encoded frames, to restart encoding.  Computing the differences and encoding I-frames is implemented for both intra-and inter-channel differences. The encoded frames are transmitted to a decoder for display.  The method uses artificial intelligence or fuzzy logic.
