Title: Elastic plug assembly for medical device
Inventor: BRIMHALL GREG L
IPC: A61M39/06
Filed: 1995-10-04
Abstract: An elastic plug assembly is provided for selective penetration by a needle. The elastic plug assembly comprises an elastic plug that is retained in a radially compressed state by a rigid plug retainer. The combined elastic plug and rigid plug retainer may be secured in a housing formed from an elastomeric material. The elastic plug may be penetrated by a needle. Upon removal of the needle, the radially compressed elastic plug will be urged toward its compressed condition with the space that had been occupied by the needle being completely filled to effectively achieve the sealing function of the plug. Needles may repeatedly be penetrated through the plug and removed as necessary, and the plug will efficiently return to its substantially solid sealed state after each successive needle removal.

Title: Apparatus and method for feeding print media from a stack
Inventor: MARZULLO JOSEPH H
IPC: B65H1/02
Filed: 1995-11-24
Abstract: The sheet feeder includes a tray having a pusher mechanism mounted at a rear portion and a feeder mechanism mounted at a forward portion. The pusher mechanism is driven through a spring wrap clutch which includes a ratchet which engages a pawl mounted on the feeder mechanism. When the feeder mechanism is in a first position the pawl is disengaged from the ratchet and the clutch is free to rotate and engage the pusher mechanism which advances the stack of sheets against the feeder mechanism, driving the feeder mechanism back to a second position where the pawl engages the ratchet, disengaging the spring wrap clutch and halting the pusher mechanism. As sheets are fed from the stack a spring urges the feeder mechanism back towards the first position, disengaging the ratchet and engaging the clutch and repeating the cycle. A spring maintains a substantially constant normal force between the feeder mechanism and the stack as the feeder mechanism moves between the first and second positions.

Patent CA-2170695-A1 (CA)
Title: Reverse wiring indicator for gfci receptacles
Inventor: MISENCIK JOHN
IPC: H01R13/648
Filed: 1996-02-29
Abstract: A reverse wiring indicator for a GFCI receptacle alerts the installer in the event that the AC source has been improperly wired to the load or feedthrough terminals of the receptacle rather than to the source or input terminals. The reverse wiring indicator operates by open-circuiting one of the load or feedthrough terminals of the receptacle, and may take the form of a removable barrier which inhibits conduction through one of the power contact sets of the GFCI circuit breaker until the receptacle has been installed and successfully tested. The contact set through which conduction is inhibited is the one other than that to which the TEST switch is connected, and the other contact set is allowed to conduct in the normal manner.      The removable barrier prevents a current path from being established through the load or feedthrough terminals of the receptacle in the event that the receptacle has been miswired, thereby preventing the TEST switch from falsely tripping the circuit breaker in that situation, but does not prevent the TEST switch from operating normally to trip the circuit breaker if the receptacle has been properly wired. The removable barrier may be provided in the form of a thin strip of electrically insulating material (such as Mylar tape] which is held between one set of closed power contacts and protrudes through the front of the receptacle housing so that it is conspicuous and easily removable.

Title: Mixtures of polyamino acids and citrate
Inventor: WOOD LOUIS L
IPC: C11D3/20
Filed: 1994-09-07
Abstract: Polyamino acids or their salts mixed with citric acid or its salts, in a ratio of 75:25 to 0.1:99.9, polyamino acid or its salt to citric acid or its salts, and especially in a ratio of 1:1 to 1:99 polyamino acids or their salts to citric acid or its salts, provide a much higher rate of chelation of calcium ion than expected on the basis of the addition of the polyamino acid to citric acid.

Title: A process for adding reinforcement fibres to cast stuff, and a device for providing and adding such fibres
Inventor: NORDIN ARNE
IPC: B21F11/00
Filed: 1994-10-05
Abstract: A method and a device for producing reinforcement fi-bres and adding them to con-crete stuff. The fibres are pro-duced from a continuous wire (6) by means of wire pieces, which form the fibres, being detached consecutively from the wire and then, in turn, by virtue of their kinetic energy, being flung into a mixer in which the concrete stuff is undergoing mixing. A device which is suitable for implement-ing the method comprises a wire spool which is mounted on a bal-ance and from which the wire (6) runs to a wire-impelling unit (4), after which a fibre-detaching unit (8) is arranged which engages with the wire which has been fed forward by the impelling unit and consecutively detaches wire pieces from the wire. The fibres which have thus been detached pass through a nozzle tube (46) which is arranged downstream of the detaching unit (8) and which guides the fibres into a subse-quent mixer which contains con-crete stuff. The wire-impelling unit (4) and the fibre detaching unit (8) each comprise a driven wheel (10 and 28, respectively), which engages with the Wire, and a guide roller (12 and 30, respectively) which interacts with this wheel.

Abstract: A layout is provided for RF power transistors that reduces common lead inductance and its associated performance penalties. An RF transistor cell is rotated 90.degree. with respect to a conventional RF transistor cell so as to locate bond pads nearer the edge of a silicon die, reducing bond wire length and common lead inductance and thereby improving performance at high frequencies.

Title: Process for regeneration of rubber
Inventor: FISHER JAMES F
IPC: B29B13/10
Filed: 1996-06-07
Abstract: Reclaim rubber is obtained from vulcanized rubber by subjecting a mass of the rubber to mechanical working applying highly intensive impact forces to the mass. The process is relatively energy efficient and therefore produces reclaim rubber at relatively low cost. It also mitigates the objectionable smell associated with known reclaim rubber products. The process can be used with the addition of small amounts (usually of the order of 1% to 2% by weight) of various chemicals known to retard cure rates in rubber, but it has been shown to be efficient on a production basis to operate without the addition of, or dependence on, any added chemicals.

Filed: 1996-10-11
Abstract: Vehicles, notably heavy duty trucks, equipped with torque reactive suspensions, such as trailing arm air suspensions, are susceptible to driveline vibration and wheel hop due to engine produced torque. According to this invention such driveline vibration and wheel hop can be suppressed by preventing frame rise from occurring. Suppression can be accomplished by providing one of several forms of frame rise control means operative between the vehicle drive axle and the vehicle frame. One form of frame rise control means utilizes rebound control leaf springs on opposite sides of a vehicle. Another form utilizes shock absorbers each of which incorporates a spring mounted on the piston rod. Another form utilizes hydraulic cylinders, each having a source of pressurized hydraulic fluid connected to the chamber of the cylinder on the rebound side of the piston and the chamber on the opposite side of the piston vented to atmosphere. Another form utilizes hydraulic cylinders each having a source of hydraulic fluid connected to the chambers on opposite sides of the piston with a valve operative to block flow of hydraulic fluid from the chamber on the rebound side of the piston. Still another form utilizes an elongated endless elastic strap embracing the shock absorbers.
