Abstract: The chewing tablets proposed contain a small amount of effervescent agent (which gives a pleasant fizzy feeling in the mouth), active substances and fillers in amounts chosen so that the tablets will nevertheless dissolve, with the exception of any insoluble or poorly soluble active substances, in 100 ml of water at 15 to 20°C in less that 120, preferably 90, seconds. This is achieved by virtue of the fact that the acid and/or carbonate particles in the effervescent agent are coated with a preferably readily, i.e. rapidly, soluble hydrocolloid and/or the active substance is free of encapsulation agents and the tablet mixture is free of lubricants. Tablet weight is 600 to 1500 mg, preferably only 700 to 1200 mg.
Patent CA-2219333-C (CA)

Granted: 2008-07-29
Abstract: A local area data network (26) interconnects devices (12, 14, 20, 30) which make up a video surveillance system (10). The devices attached to the local area network are divided into distinct classes (12, 14, 30) which are polled with different degrees of frequency. Devices are dynamically reassigned from class to class depending on each device's current requirements for network access. Group polling is also employed, with resolution of contention by means of a probing algorithm. Negative responses to polling messages are formed as a series of line transitions that require less time than transmission of a single data byte. Polling messages have a distinct length in terms of bytes that is shorter than any other message transmitted on a network. Polled devices (12, 14) are permitted to transfer data directly to peer devices in response to polling messages.

Title: Improved delivery of diagnostic and therapeutic agents to a target site
Inventor: GRIFFITHS GARY L
IPC: A61K39/395
Filed: 1996-06-07
Granted: 2010-05-11
Abstract: An in vivo method for delivering a diagnostic or therapeutic agent to a target site in a mammal, wherein a targeting species including a targeting moiety and a diagnostic or therapeutic agent or a binding site for a subsequently administered diagnostic or therapeutic agent conjugate, the targeting moiety having a primary binding site whereby it specifically binds to the target, is administered and allowed to accrete at the target site, is improved by injecting into the circulatory system of the mammal a clearing agent that binds to the primary binding site of the targeting species, whereby non-localized primary targeting species is cleared from circulation. The method is especially useful in pretargeting methods because the clearing agent does not remove the primary targeting species or block secondary binding sites of the primary targeting species.

Title: Novelty lamp
Inventor: KAVIANI ALI
IPC: F21S10/00
Filed: 1998-04-09
Granted: 2002-06-25
Abstract: A novelty lamp which comprises a transparent container with a top surface, a bottom surface, an outer portion, and an inner portion. The inner portion extends upwardly from the bottom surface of the container and defines a hollow area. The bottom surface of the container is mounted in a base member. Two substances are received in the container. One of the substances has a higher relative density at room temperature and is immiscible with the other substance. Upon application of heat, which is supplied by a light bulb mounted within the base member, globules of the substance with the initially higher relative density become less dense, rise in the other substance and flow around the outer and inner portions of the container. As the globules rise toward the top surface of the container they cool, become more dense and drop back down toward the bottom surface of the container.

Granted: 2008-05-06
Abstract: A railcar unit has a pair of deep sidewalls and a cradle mounted between the sidewalls for carrying coils. The sidewalls span the distance between the two railcar trucks, and act as a pair of deep beams for carrying vertical loads. The deep sidewalls are arranged to extend above and below the centre sill of the cradle and to give vertical stiffness to the car. The centre sill is a straight through sill for carrying buff and draft loads between the couplers. The cradle is made from a set of cross bearers welded to the centre sill to form a series of segmented beams, covered by plating. The cross bearers are welded to the sidewalls at lap joints. The cross bearers are all of the same design and can be made from a rolled beam. The sidewalls have their deepest section at mid-span, and are tapered to a thinn er section toward the end structure of the cars. The tapering includes provision of an access way between the railcar truck wheels and the sidewall to permit brake maintenance.
