Title: Improved method for forming polymers
Inventor: LAU WILLIE
IPC: C08F2/10
Filed: 1995-10-27
Abstract: An aqueous polymerization method is disclosed for forming polymers containing, as polymerized units, at least one monomer having low water solubility, including the steps of: (1) complexing at least one monomer having low water solubility with a macromolecular organic compound having a hydrophobic cavity; and (2) polymerizing in an aqueous system from about 0.1% to about 100%, by weight of the monomer component, based on the total weight of the polymer, of the complexed monomer having low water solubility with from about 0% to about 99.9% by weight, based on the total weight of the polymer, of at least one monomer having high water solubility. The method is also useful for forming aqueous solution polymers having low water solubility. The method is useful for polymerizing, in an aqueous system, aqueous solution polymers or emulsion polymers, particularly random copolymers, of monomer having a low water solubility which heretofore could not be made satisfactorily without the addition of an organic solvent, comonomer or a high level of surfactant to aid in solubilizing the monomer having low water solubility. The method is also useful for improving the efficiency of chain transfer agents having low water solubility used in aqueous solution and emulsion polymerizations.

Title: Macromolecular contrast media for mr imaging
Inventor: BRASCH ROBERT C
IPC: A61K49/00
Filed: 1994-05-19
Abstract: A macromolecular contrast agent for magnetic resonance imaging of the vascular system is constructed of a polymeric backbone structure with a plurality of spacer arms bonded to the backbone structure, each spacer arm terminating in at least one paramagnetic complex. The polymeric backbone thus serves as an amplifier by supporting a multitude of paramagnetic complexes, and the spacer arms contribute to the molecular weight. The spacer arms further contribute useful properties to the agent, such as hydrophilicity and the ability to cleave at a relatively rapid rate in blood.

Patent CA-2166732-A1 (CA)
Inventor: CHANG PETER J Y
IPC: B05C17/01
Filed: 1995-12-19
Abstract: Simple and economical drive mechanisms for caulk dispensing devices that give a drip-stop release feature to improve control over the bead of caulk. A first embodiment includes a release lever encircling the plunger shaft and extending upwardly therefrom, and an elastic washer encircling the plunger shaft between the housing and release lever for frictional sliding therebetween. The release lever and washer ride forward on the plunger shaft while the trigger is retracted, and when the trigger is released the washer rides backward on the plunger shaft thereby driving the release lever until it engages the plunger shaft to prevent further retraction. In another embodiment, the floating washer and release lever are replaced by a first compression spring that is formed with a forward constricted end having increasingly tighter helical coils to frictionally grip the plunger shaft. Upon retraction of the trigger, the first grip drives the plunger shaft to overcome the friction of the constricted end of the first compression spring and the plunger shaft slides on through. Upon release the first gripping member and compression spring are able to retreat a bit until blocked by the frame. At that point the constricted end of the spring grips the plunger shaft and prevents further retraction, thereby cutting off the flow of caulk and providing a dripless release feature by relieving pressure in the cartridge upon initial release of the trigger.
Patent CA-2167034-A1 (CA)
Title: Mechanical automatic aisle lock
Inventor: JANSON STEVEN L
IPC: A47B53/02
Filed: 1996-01-11
Abstract: A mechanism that automatically locks a movable storage unit against closure of an aisle between the unit and a blocking object such as a facing movable or stationary storage unit or a wall, while permitting continued opening of the aisle, without any electrical controls or power. A binding device is shiftable between a binding state permitting movement of the movable storage unit only away from the facing storage unit or wall, and a non-binding state permitting movement of the unit in either direction. The mechanism includes a clutch wheel which rotates with the wheels of the movable storage unit, and a resilient binding wheel, insertable between the clutch wheel and a stationary binding block. When the binding wheel is inserted as described, it will bind and preclude the clutch wheel from continuing to rotate towards the binding block. A latch is capable of holding the binding wheel out of binding state. An aisle sensor and a manual lock button are provided to free the binding wheel from the latch, and again permit it to resume binding state. An unlock button is also provided for resetting the binding wheel to the non-binding state, again permitting movement of the mobile storage unit toward the facing storage unit or wall.

Patent CA-2170294-A1 (CA)
Title: Vermi (worm) organic digester
Inventor: EGGEN ALBERT BRIGGS
IPC: C05F17/02
Filed: 1996-02-26
Abstract: A vermi organic digester comprises a mass of red worms feeding on a layer of biodegradable organics suspended on a grating system in a ventilated enclosure. Biodegradable organics are fed into the upper chamber where they are spread over a layer of worms, their castings (digested biodegradable organics) and biodegradable organics. As the worms digest the biodegradable organics they migrate upwards through the layer in search of food leaving behind their castings. As the castings build up on the suspended grating a raking system loosens the lower most portion of the castings causing some to fall through the grating system into the lower compartment. The castings are removed, manually or mechanically from the lower compartment. A thermostatic controlled ventilation system maintains an optimal operating temperature in the vermi organic digester.

Inventor: LAI MING
IPC: H01S3/00
Filed: 1994-01-19
Abstract: A single-grating method and apparatus is described for a laser pulse stretcher and compressor (30). The method and apparatus exploit a two-layer vertical structure: one layer for the stretcher section (elements 32, 34, 36, and 38) and one layer for the compressor section (elements 32, 40a, and 40b). This allows additional components to be disposed between the respective stretcher and compressor sections. Applications are described for chirped-pulse and regenerative amplifiers, where tuning is desired. When a change in the input wavelength is applied, only one rotational adjustment is required to resume the alignment of the whole stretcher and compressor.

Abstract: A system and method of using two-way paging to establish communications with a mobile party having a Personal Telephone Number.  The mobile party is equipped with a two-way pager which the party may use to provide call control. The pager is periodically queried by a network and/or paging service to determine whether or not the pager is reachable.  If the pager becomes unreachable, and thereafter a call is placed to the party's Personal Telephone Number, the network routes the call to a default station.  If the pager is reachable, any one of a number of alternative call routing procedures may be invoked including: registration type routing, call-by-call routing, revertive calling, call examination routing, and subsequent routing. In one possible embodiment, a Customer Routing Point is used to store the pager status along with other call routing information, and a Network Control Point is used to carry out the appropriate routing procedure.  Other possible embodiments include: using an adjunct to perform the functions of the Customer Routing Point and Network Control Point; and combining an adjunct with a Customer Routing Point and Network Control Point.

Title: Household appliance with electronic program control
Inventor: SAMS WALTER
IPC: D06F34/08
Filed: 1996-12-06
Abstract: A household appliance, in particular a washing machine or a dishwasher, is operated by an electronic program control (6).  An electric load (5) in the appliance is switched on and/or off via a semiconductor component or a relay.  If this semiconductor component or the relay fails, e.g. by short circuit or by contact sticking, a safety device is activated after the recognition of the failure of the component.  The safety device disconnects the load (5) from its voltage supply.  In a preferred design, an intentional water overflow takes place after the failure of the component, which results in the actuation of the water safety device.  Thereupon the water safety device switches off the electronic program control (6) and thus also the load (5).
