Patent CA-2090719-A1 (CA)
Inventor: AEBISCHER PATRICK
IPC: C12N11/00
Filed: 1992-06-25
Abstract: Methods and devices are disclosed for the delivery of an active factor from an implanted co-culture of an active factor-sec-reting cell obtained from a first source and an augmentary substance-secreting cell obtained from a second source different from the first source to a target region in a subject. The co-culture is maintained within a biocompatible, semipermeable membrane in which the augmentary substance secreted by the augmentary substance-producing cells stimulates the active factor-producing cells to secrete active factor. The semipermeable membrane permits the diffusion of the active factor therethrough while excluding detrimental agents present in the external environment from gaining access to the co-culture.

Title: Sanding device for road vehicles
Inventor: CONNOLLY MICHAEL
IPC: B60B39/04
Filed: 1993-04-15
Abstract: ABSTRACT an improved sanding device for road vehicles It is known that some large road vehicles are equipped with air compressors and a supply of sand which the driver can cause to be blown out towards the wheels in the event of a skid occurring on slippery road surfaces.          This procedure is inefficient because time is lost in operating the control and because it is an added distraction to the driver.            In this invention, if the driver applies the brakes of the moving vehicle and a skid develops, the device automatically deposits anti-skid material at the wheels.  The power to accomplish this is supplied by the battery of the vehicle.

Title: Method of and apparatus for subdividing webs
Inventor: ROEHRDANZ ALBRECHT
IPC: B65H35/07
Filed: 1993-04-19
Abstract: ABSTRACT      A  web  of  coherent  labels  or  coherent  blanks  of wrapping material  is  advanced along an elongated path toward a severing station where the web is cut at selected intervals  by  an  orbiting  knife  in  cooperation with  a stationary  or  moving  knife  to  yield a  succession  of sections of desired length.  If the web is to be arrested for a shorter or longer period, it is first accelerated above its standard speed and is thereupon decelerated to zero speed during the last interval of advancement so that the length of the leader of the web extending beyond the severing station matches the desired length.  Analogously, when the web is restarted,  it is accelerated above the standard  speed  and  is  thereupon  decelerated  to  such standard speed during the first interval of advancement so that the knives sever a section whose length again matches the desired length.  If a first web is to be followed by a second web, the leader of the second web is maintained at a standstill at the severing station, and the second web is accelerated first above the standard speed and is thereupon decelerated to standard speed during an interval following stoppage or expiration of the first web so that the  length of the first separated section of the second web again matches the desired length.

Inventor: KOSMYNA MICHAEL J
IPC: B01D46/40
Filed: 1993-06-15
Abstract: Disposable air filter includes a filter element formed from a stacked plurality of annular disks.  The disks are formed from a sorptive material and expand upon absorption of oil or water droplets.  The disks are slightly compressed by a movable baffle.  The baffle floats upon a stream of air entering the filter and directs the air radially through the filter element.  The air flows between and through the disks with a resulting low pressure drop across the filter.  As the disks expand, the baffle shifts axially within a filter housing to maintain the pressure drop across the filter element.

IPC: C08F236/04
Filed: 1993-08-20
Abstract: Abstract of the Disclosure PROCESS FOR THE SYNTHESIS OF ISOPRENE-BUTADIENE RUBBER       The subject invention relates to a technique for synthesizing rubbery non-tapered, random, copolymers of 1,3-butadiene and isoprene.  These rubbery copolymers exhibit an excellent combination of properties for utilization in tire sidewall rubber compounds for truck tires.  By utilizing these isoprene-butadiene rubbers in tire sidewalls, tires having improved cut growth resistance can be built without sacrificing rolling resistance.   Such rubbers can also be employed in tire tread compounds to improve tread wear characteristics and decrease rolling resistance without sacrificing traction characteristics.  This invention more specifically discloses a process for the synthesis of isoprene-butadiene rubbers which comprises copolymerizing isoprene monomer and 1,3-butadiene monomer in an organic solvent in the presence of a catalyst system which is made by the sequential steps of (1) mixing (a) an organoaluminum hydride,  (b) a member selected from the group consisting of aliphatic alcohols, cycloaliphatic alcohols, aliphatic thiols, cycloaliphatic thiols, trialkyl silanols, and triaryl silanols, and (c) optionally, 1,3-butadiene in an organic solvent to produce a modified organoaluminum catalyst component; (2) adding an organometallic compound which contains a metal from Group III-B of the Periodic System to the modified organoaluminum catalyst component to produce a Group III-B metal containing catalyst component; and (3) adding a compound which contains at least one labile halogen atom to the Group III-B metal containing catalyst component.

Title: Valve lock
Inventor: HOVING GEORGE III
IPC: F01L3/10
Filed: 1993-10-15
Abstract: ABSTRACT An improved valve lock comprises a plurality of tapered arcuate sections that fit together to provide a sleeve that fits on the tip of a valve stem, with the inner surfaces of the arcuate sections having raised ridges thereon that mate with corresponding valve lock grooves in a valve stem.  The axial position of the ridges in the valve locks of the present invention are modified from the position of the ridges for an original equipment engine by an amount sufficient to compensate for a change in compression strength of a used valve spring or a variation in position of the valve stem due to grinding of the valve seats or valve stems.  Desirably, the ridges are positioned thirty thousandths (.030) of an inch outwardly from the position of the ridged in an original equipment valve lock for an engine where the valves have been ground and new valve springs are used, and the ridge position is adjusted sixty thousandths (.060) of an inch outwardly from the original equipment position when the valves have been ground and the original springs are reused.  The valve locks are color coded to readily identify the appropriate valve locks for each particular application.
