Granted: 2004-08-10
Abstract: The present invention provides an apparatus for cooling and/or gassifying a liquid (12) stored in a container (10) having an outlet (10b). The apparatus comprises an adsorbent (14) for receiving and adsorbing under pressure a quantity of gas and a three position cap (16). 1n a first position, said cap (16) simply acts to seal the contents within the container whilst in a second position it acts to cause release of adsorbed gas from adsorbent (14) which then passes through the beverage (12) thereby gassifying and/or cooling said beverage. A third position of the cap (16) allows for its removal from container (10) such that the beverage may be dispensed. The container may be provided with a thermochromatic coating to indicate when the liquid is at a predetermined temperature.

Title: System for improving the quality of a received radio signal
Inventor: BOTTOMLEY GREGORY E
IPC: H04B1/715
Filed: 1997-12-15
Granted: 2006-12-05
Abstract: A delay spread is created in a digital radio signal to reduce the coherence bandwidth and facilitate frequency hopping to reduce the effect of fading losses within an enclosed propagation environment. The delay spread is introduced into the signal in several ways. One technique disclosed employs a transmitter (21) with two separate antennas (26, 27) one of which transmits the digital signal and the other of which transmits the same signal after a phase delay (25) has been introduced into the signal. The carrier frequency of the signals is hopped between at least two frequencies and the receiver processes the resulting signals. In another embodiment, a single transmit antenna (42) is used but the signal is received by two different antennas (43, 44) with the output signal from one of those antennas being phase delayed (45) before combining (46) it with the other prior to processing by the receiver circuitry (47). Phase delay (115) is also introduced at baseband into the signals to be transmitted by rotating the I and Q  components of the waveforms before modulation.

Abstract: A power-operated vehicle door locking assembly including separate inner and outer door locking mechanisms connected with a housing assembly and an electric motorized system oper-able to selectively move (1) the inner door lock-ing mechanism between an inoperative and an inner door locking position in response to inner manual electric motor energizing actuations and (2) the outer door locking mechanism between an inoperative and an outer door locking posi-tions in response to outer manual electric motor energizing actuations. The arrangement is such that an outer manual electric motor energizing actuation without a corresponding inner manual electric motor energizing actuation causes a door latching assembly when in a door latching posi-tion to be incapable of being moved into a door unlatching position by an outer door latch releas-ing mechanism while at the same time the door latching assembly is capable of being moved into the door unlatching position thereof by an inner door latch releasing mechanism.

Abstract: A method for preparing collagenous biological tissues for use as implantable bioprosthetic material, and articles prepared thereby. The method generally comprises the steps of a) contacting the tissue with an aldehyde fixative to effect cross-linking of the connective tissue protein(s) and subsequently b) contacting the tissue with a polyglycidyl ether. The treatment of the cross-linked tissue with the polyglycidyl ether serves to mitigate the tissue's propensity to undergo calcification following implantation in the body.

Title: Equine dental speculum
Inventor: WILLIAMS TODD
IPC: A61D15/00
Filed: 2001-03-27
Granted: 2004-07-20
Abstract: A one-piece equine dental speculum having an open frame, extending from one side of a horse's mouth, across in front of the incisors to the opposite side of the mouth. Bite plates are affixed at the front of the speculum to engage the incisors when the speculum is fully inserted. Two V-shaped projections extending rearward from each end of the bite plates act as wedges to engage the incisors and force them towards the upper and lower bite plates, forcing the jaws apart. Simply, insertion requires placing the speculum frame around the horse's mouth, placing the V-shaped projections between the upper and lower incisors and pushing until the incisors are "walked" along the upper and lower surfaces of the V-shaped projections to open the jaws. Once fully inserted, the incisors are held in place at the bite plates preventing the jaws from closing. Nose and head straps hold the speculum in place in the horse's mouth. The projections are narrowly spaced to further prevent the user from inserting their hands into the opened horse's mouth, lowering the risk of injury to the user.
