Patent CA-2095544-C (CA)
Inventor: TAYLOR DONALD MOREY
IPC: E06B3/663

Granted: 1999-05-18
Abstract: An insulative, gas impermeable spacer frame is provided for the precision separation of two or more transparent glass or plastic panes,  and is hermetically sealed in place to prevent the ingress or egress of moisture vapor, and to contain various noble gases, or air, between the adjacent panes, being used in insulated lights for windows and doors.      The  spacer is made of insulative organic material of suitable stiffness such as cardboard, or plastic over which is applied a  coating or lamination of gas  and moisture vapor barrier materials, thus forming a composite insulative web which may be fabricated into tubular structures to form separate frame units.  Such spacer structures may possess extremely low thermal conductivity,  so as not to constitute a thermal bridge between the panes being separated, thereby diminishing and even eliminating the problem of window edge frosting and/or peripheral dew point development, such as occurs when metal spacer devices are used.      The hollow, tube-like spacer form may be used to contain desiccant materials for absorbing moisture and an organic vapors that evolve or may be present within the hollow window cavity, created when the spacer is sealed in place.   The material or materials for the improved insulating spacer may be supplied in a  flexible,  planar,  ribbon-like  form,  of  continuous  length rather or as a preformed stiff section,  as at present,  thus enabling the economic advantages of making various sizes of spacer frames without the cut-off losses which otherwise occurs when  such spacer  assemblies  are  cut  from stock lengths of rigid, preformed hollow profile.  However, the provision of the unique  spacer, made  up  into  predetermined  lengths  also  is contemplated.   The rigid stock lengths are then readily square cut  or  mitered  and  jointed  with  insert  joints,  to  form insulating spacer frames.   The provision of a protective film, against ultra violet degradation may also be readily incorporated in the spacer or coating formulation.

Abstract: A door- or window sash which is pivotable relative to a door- or window frame between open and closed positions can be releasably affixed to the frame in the closed position in response to turning of a handle which can shift an elongated carrier relative to the frame between two spaced-apart end positions. The carrier supports a series of longitudinally spaced-apart projections each of which fully engages a complementary retainer on the sash during different stages of movement of the handle from one end position to the other end position.      The arrangement may be such that the projection nearest to the handle is first to engage the complementary retainer on the sash, that the projection which is adjacent the nearest projection is next to engage the corresponding retainer, and so on. A safety device can be provided to releasably lock the carrier in the other end position.

Filed: 1992-05-15
Granted: 2005-11-22
Abstract: A portable computer system includes a protected mode microprocessor (311) capable of operating in restricted and unrestricted modes, and an arrangement which in response to a predetermined condition saves information from the processor and then forcibly switches the processor to its unrestricted mode of operation. When running a multi-tasking operating system where an application program is being executed in a restricted mode, certain types of processing can be carried out after the unrestricted mode is entered due to the predetermined condition, then the interrupted application can be resumed with the restricted mode back in effect. An idle mode feature can automatically decrease and increase the speed of the processor clock (387) when user activity stops and later starts again, to conserve power.

Abstract: Highly-purified immunologically-effected recombinant protein encoded by a gene of a full-length wild-type Borrelia lipoprotein, particularly the OspA encoded by the ospA gene of B.burgdorferi, useful in vaccines and test kits for Lyme disease, is prepared by inducing protein production from a host organism transformed by a plasmid vector containing the cloned gene and subsequently recovering and purifying the protein. The grown organism is lysed and contacted with a surfactant, particularly Triton X-114, which selectively extracts the desired protein from the lysed cells. Upon heating the resulting mixture to mildly-elevated temperature, a detergent phase separates out and is recovered separate from the other phases. The detergent phase is further purified from residual protein by column chromatography.

Granted: 2004-06-22
Abstract: The present invention is directed to a method for retaining the antimicrobial activity of the byproducts of growth of microorganisms during storage. In the method, a pasteurized low fat or skim milk substrate is provided. The substrate is inoculated with an S.lactis culture. The substrate is then fermented to cause growth of the culture and the release of metabolic byproducts, including nisin, from the culture. The fermented substrate is loaded into a container. The headspace of the container is then flushed with a quantity of an inert gas in excess of the amount required to displace all of the ambient air in the headspace. In an important embodiment of the invention, a small amount of a CO2 producing chemical, such as calcium carbonate, sodium carbonate and sodium bicarbonate, is mixed into the fermented substrate. The CO2 producing chemical has the effect of both stabilizing the antimicrobial activity of the cultured substrate and aiding in the release of nisin from the cells produced during fermentation of the substrate.

The member (1.2) can be either a steel pipe or a rod. The windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) can either be in the form of steel wires or be strips of material. The numbers of windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) wound around the member (1.2) in a clockwise and anti-clockwise direction should be equal. Ideally, the windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) are attached to the member (2) on a continuous basis except for the ends which are left free. The strain is generated from actuators, preferably made from piezo electric materials, which can either be attached to the ends of the windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) or form part of the windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10). The actuators can be controlled by control signals which are calculated by a control unit based on signals produced by vibration sensors (1.13, 1.14), ideally, part of the member (1.2) is formed to produce an impedance mismatch with the rest of the member (1.2). This can be achieved by having a flexible section (1.2a) within the member (1.2). The windings (1.5, 1.6, 1.7, 1.8, 1.9, 1.10) are usually attached across this section (1.2a).

Title: Non-reusable syringe
Inventor: NATHAN ELIZABETH S
IPC: A61M5/50
Filed: 1996-01-22
Granted: 2002-12-17
Abstract: Non-reusable syringe having a syringe body, a hypodermic needle and a slidable piston for drawing and discharging fluid through the needle. In one embodiment, the non-reusable syringe includes a movable engagement member.  A first position of the movable engagement member permits initial withdrawal of the piston, allowing fluid to be drawn into the syringe. Initial withdrawal of the piston moves the movable engagement member into a second position.  After the fluid has been substantially discharged, the second position of the movable engagement member captures the piston and prevents the piston from being withdrawn again.  In another embodiment, the movable engagement member is mounted on, and movable with respect to, the piston.  The non-reusable syringe can also include a releasable connection between the piston and the piston driver.  Once the piston has been captured, a second attempt to use the syringe will separate the piston from the piston driver, further preventing reuse of the syringe. The non-reusable syringe can also include a stop mechanism to prevent complete withdrawal of the piston, thereby precluding the possibility of tampering with or removing the movable engagement member and/or the piston.

Granted: 2000-05-16
Abstract: Synchronizing wireless base stations by reception of a synchronization signal that is transmitted in an unused B channel of an ISDN link interconnecting a switching network and the base stations. The synchronization signals are generated by the tone circuit of the switching network which advantageously is a digital signalling processor (DSP). Each base station is interconnected to the switchingnetwork via two basic rate interface (BRI) links. Each base station can handle amaximum of three wireless handsets thus leaving one of the four B channels present in the two BRI links unused. It is this unused link that is utilized to transmit the synchronization signals from the switching network to the base stations. Furthermore, the switching network is configured in such a manner that all base stations receive the synchronization signals at the same time over the unused B channels.

Abstract: The invention relates to a lifting rod for the lower steering arm of a tractor.  At the ends of the lifting rod there are attached connecting elements in the form of a connecting yoke 6 and a ball joint 7.  The connecting yoke 6, by means of a threaded rod 9,  is threaded into a threaded bore 10 of a tubular rod element 11.  The rod element 11 is received in the housing bore 21 of the housing 8 so as to be movable along the longitudinal axis 17.  The rod element 11 and the housing 8 are able to assume two different positions relative to one another, with the lifting rod length being fixed in one of said two positions.  In the other position, both may assume a floating relationship relative to one another.  To allow the lifting rod length to be set even when the lifting rod is in the mounted condition and to ensure that both parts do not change their respective positions even when in use, it is proposed that in the rigid position, the plug-in pin 24 engages a recess 13 in the rod element, so that support is provided in the shortening direction and in the direction of rotation, whereas for the direction of extraction there are provided stops which prevent any lengthening.   After the plug-in pin 24 has been extracted, the rod element 11 can be turned by 90°, thus enabling the plug-in pin to pass through the slot 14 in the rod element 11; the lifting rod length is shortened, but rotation is prevented.
