Patent CA-2029856-A1 (CA)
IPC: F16K31/40
Filed: 1990-11-13
Abstract: The fitting has in each case a hydraulically operable shutoff valve (40, 42) for hot and cold water. The diaphragm-shaped closure part (56) interacts with the valve seat (52). Provided on the side opposite the valve seat (52) is a pilot control space (60) which is con-nected through the passage (62) to the annular channel (48) and the corresponding feedline (20). Via control lines (86'), each pilot control space (60) is connected to the outlet line (24) via an auxiliary valve (70'). The two auxiliary valves (70') are constructed on a ceramic disk valve (72) and can be operated jointly. When the auxiliary valves (70, 70') are closed, the pressure in the pilot control space (60) corresponds to the pressure in the annular channel (48), the shutoff valves (40, 42) are closed. By rotating the operating shaft (86) the two auxiliary valves (70') are opened, by which means the pressure in the pilot control spaces (60) drops. The closure part (56) is lifted from the relevant valve seat (52) and the shutoff valves (40, 42) are opened. When the auxiliary valves (70') are closed by rotating the operat-ing shaft (86), the pressure in the pilot control spaces (60) rises again, by which means the shutoff valves (40, 42) are closed. The joint operation of both shutoff valves (70, 70') requires extremely little energy.

Abstract: ABSTRACT            METHOD AND APPARATUS FOR ABRADING            An abrading apparatus for abrading tire tread compounds has a plurality of test stations (14) and a drive module (16) coupled to the test stations.  Each test station (14) has a grindstone (20) and a sample wheel (24), both of which are rotatably driven by the drive module (16). Each sample wheel (24) has an outer layer made of the tire tread compound to be abraded.  The sample wheels (24) are engageable with the grindstones (20) to abrade the tire tread compounds against the grindstones.  Each test station (14) also has a dust transfer wheel (40) engageable with the sample wheel (24), and a chalk member (44) engageable with the dust transfer wheel (40).  The chalk member (44) transfers chalk dust to the dust transfer wheel (40) which, in turn, transfers chalk dust to the sample wheel (24), to dust the interface between the sample wheel (24) and the grindstone (20). The drive module (16) has a gear assembly (78, 88, 90, 92, 94, 98) to change the velocity of the sample wheels (24) relative to the velocity of the grindstones (20), to adjust the slip value and, therefore, the degree of abrasion of the sample wheels (24).  The abrading apparatus can be employed to abrade tire tread compounds at different levels of abrasion severity, to predict the irregular wear resistance of the compounds.

IPC: A01D34/74
Filed: 1991-04-24
Abstract: Lawn mower height-adjust systems include three embodiments.  Two permit the user to adjust the position of the deck relative to each wheel individually.  The third permits the user to adjust the positions of all four wheels simultaneously, aided by a counterbalance system.  A modification of the third embodiment is available to automatically bypass the height-adjust mechanism in the event an abnormally high load is placed on the deck.  One of the two individual systems permits an operator to adjust the position of a respective wheel simply by removing a single nut and washer from an axle bolt.  The second individual height-adjust system permits the operator to adjust the height of an individual wheel by using one hand, and without having to disassemble the mechanism.  The system which adjusts all four wheels simultaneously links front and rear axle subassemblies with a connecting rod, and indexes all four wheels simultaneously through a release handle which is recessed in a cavity formed in the lawn mower deck.  When the operator lifts the release handle, he or she may simultaneously grasp a portion of the deck with the same hand and easily raise or lower it to a desired position. A single unitary plastic deck is the foundation for each of the three height-adjust systems, thereby significantly reducing the cost otherwise incurred by manufacturing three separate types of lawn mowers.

Abstract: SEPARATION OF BACTERIA FROM ORGANIC MATTER                 ABSTRACT OF THE DISCLOSURE A  filtration  system  and  method  for  rapidly recovering bacteria from feces and other organic matter has been developed.  Chicken feces is filtered through a sequence   of  essentially  non  absorbent   screens   of selected,  gradually  decreasing  pore  sizes.   The  three stage filtration system recovered 90% of the Salmonella spiked into 10 grams of chicken feces and greater than 70% of the Salmonella spp.  from 10 grams of naturally infected feces in less than 15 minutes.  Although fecal constituents  often  interfere  with  the  detection  of bacteria by most immunologically or nucleic acid based probes,  the  bacteria  recovered  by  filtration  can  be detected by these probes.  The filtered material is also compatible   with   polymerase   chain   reaction  (PCR) technology.   The use of the filtration system improved the recovery of Salmonella spp.  from feces by standard culture methods.

Inventor: LEBKOWSKI JANE S
IPC: C07K14/015
Filed: 1991-10-30
Abstract: A simplified method to produce recombinant adeno-associated virus (AAV) vectors is described. The procedure involves the use of chimeric plasmids which incorporate the Epstein Barr nuclear antigen (EBNA) gene, the latent origin of replication of Epstein Barr Virus (oriP), and a recombinant AAV genome. The chimeric plasmids themselves are also a part of the present invention. These EBV/AAV plasmids are maintained as multicopy extra-chromosomal elements in cells, such as human 293 cells. Permanent cell lines carrying these EBV/AAV plasmids are induced to produce large amounts of recombinant AAV virus upon addition of wild-type, adeno-associated virus helper functions. Recombinant AAV vectors produced in this manner are capable of transducing exogenous genes into other human cell lines and exhibit all of the attributes of viral elements produced by conventional methods.
