Patent CA-2167787-A1 (CA)
Title: Non-reusable syringe
Inventor: NATHAN ELIZABETH S
IPC: A61M5/50
Filed: 1996-01-22
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discharged, the second position of the movable engagement member captures the piston and prevents the piston from being withdrawn again.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.

Patent CA-2170445-A1 (CA)
Title: High velocity foam dispensing device and dispensing package including the same
Inventor: CLAPP CLARENCE P
IPC: B65D83/28
Filed: 1996-02-27
Abstract: A dispensing device (16) for dispensing a fluid compo-sition, e.g., a foaming soap composition (18) has a reduc-ed risk of flashback because it has a flow path including a valve having a valve outlet of reduced cross-sectional flow area as compared to conventional dispensers, and a discharge orifice (36) whose cross-sectional flow area does not exceed the cross-sectional flow area of the mass flow rate limiting aperture of the device by more than about 1000 percent.  This enables attainment of a high but controllable discharge velocity.  The device includes a capillary dip tube (28) connected in flow communication with a valve which controls the flow of the foaming soap composition through the device by movement of the valve between a closed and a fully-open position.  The valve is biased towards its closed position by a threshold bias spring (27a) which accelerates movement of the valve to-wards its fully-open position upon actuation, i.e., causes the valve to snap to its fully-open position upon the ap-plication of opening pressure to the valve.

Title: Combined hot water and space heater
Inventor: DIMARCO GIOVANNI
IPC: F24H6/00
Filed: 1996-03-22
Abstract: An apparatus and method are disclosed for supplying domestic potable hot water and also heating an air space using a single combination unit having a common water tank and heat source for heating water therein. The water tank has an outlet for the supply of heated potable  water and an inlet for the replenishment of same with cold water. A portion of the hot water is recirculated through a heat exchanger mounted in an air handler or housing. The air handler has a blower for passing the room air through the heat exchanger to heat the air space. The temperature drop of the water circulating through the heat exchanger is limited to 6° F by using a low pressure drop heat exchanger and a relatively high flow rate circulating pump, so the supply of potable hot water is always  sufficient.  Air heating is suspended if the heated air drops below 115° F.

Abstract: An installation    for lubricating, cleaning or disinfecting conveyor belts or chains for bottles, tins or the like with devices (2, 3, 12, 14, 15) for the metered dispensing of a concentrated lubricant from a container (13), to apply the lubricant to the conveyor belts and to produce a usable solution of concentrated lubricant and fresh water, and a process for lubricating, cleaning and/or disinfecting conveyor devices in which a     lubricant, cleaner or disinfectant is diluted with fresh water to form a usable solution and the latter is applied to the conveyor device, are to be improved so that the technical complexity needed to construct a central lubricating plant is reduced, operation is simplified and reliability improved. The installation achieves this aim in that the fresh water connection (3) and the mixing unit (5) are arranged separately from the central metering unit (2) in the region of the conveyor system, a flow meter (16) for the fresh water intake is fitted upstream of the mixer unit (15) and a control line (22) leads from the outlet of the flow meter to the metering pump. In the process, this aim is achieved in that the concentrate is pumped from a point spatially separated from the conveyor system via a pipe to said conveyor system, diluted there with fresh water and the flow rate of the concentrate is controlled via the inflow rate of the mixed fresh water.

Patent CA-2174901-A1 (CA)
Inventor: SCHETTER GEORGE F
IPC: F16H57/021
Filed: 1996-04-24
Abstract: An improved structure supports a bearing in a bore provided in a portion of a transmission case and prevents relative rotation therebetween. In a preferred embodiment, the clutch housing portion of a transmission case is made from aluminum and includes an interior wall having a bore formed therein. A circumferential groove is formed in the side wall of the bore, and a compressible or elastomeric O-ring is disposed in the groove. A bearing is made from steel and includes an inner race, an outer race, and a plurality of rollers disposed between the races. As the bearing is pressed into the bore, the O-ring is compressed completely within the groove. So long as both the aluminum clutch housing and the steel outer race of the bearing remain in a relatively cold condition, the outer race will frictionally engage the inner surface of the bore, thus preventing any relative rotational movement therebetween. However, after operation of the transmission, the temperatures of both the aluminum clutch housing and the steel outer race of the bearing will increase. Because aluminum expands at a greater rate per unit temperature than steel, the inner diameter defined by the bore will increase at a greater rate than the outer diameter defined by the outer race. As a result, a small gap may be created therebetween. When this gap is created, the O-ring expands out of the groove formed in the inner surface of the bore to maintain a frictional engagement with the outer race of the bearing. Consequently, relative rotation between the two is prevented. This avoids premature wear and failure which can result from such relative rotationalmovement.

IPC: B01D53/22
Filed: 1996-08-21
Abstract: The disclosed hybrid membrane and pressure swing adsorption process can recover helium from source streams of about 0.5 to 5 percent by volume helium and concentrate the helium to a concentration of greater than about 98 percent by volume. The process comprises a membrane separation followed by two stages of pressure swing adsorption which are used in series. The source of the helium gas will be a natural gas source. The source gas will primarily contain hydrocarbons but will contain some nitrogen. The membrane unit will contain a semipermeable membrane which is permeably selective for helium and will to the extent feasible reject methane and hydrocarbons. The permeate gas will be increased in helium content by 2 to 10 times. Part of the residue gas is used in the regeneration of the adsorbent beds in the first stage of pressure swing adsorption. Each stage of pressure swing adsorption will contain a plurality of adsorbent beds, and preferably about four. In each stage the adsorbent beds will be cycled through multiple phases. In the first stage the adsorbent beds will sequentially undergo the phases of adsorption, recycle, depressurization, evacuation, helium pressurization and recycle feed pressurization. The product gas from the first stage is flowed to the second stage and in the second stage sequentially will undergo the phases of adsorption, depressurization, evacuation, purge, and helium pressurization. The offgas from the evacuation and purge in the second stage is flowed to input to the first stage. The membrane/pressure swing process efficiently produces a product stream in a high volume with a helium content of more than 98 percent by volume.
