Abstract:
In a variable displacement type hydraulic pump/motor assembly including at least one internally movable component, such as a yoke, a swashplate, and the means for moving the swashplate, the improvement includes imparting on this component absolute location indicia markings and the addition of an optical/electronic sensor unit capable of reading such indicia markings fixedly located on a housing of the pump/motor assembly and including an optical read head extending into the housing interior and located at a spaced distance from the indicia markings for reading same, relative to a reference location, and producing a signal indicative of the absolute position of the movable component. The signal can then, in turn, be used for controlling the displacement of the pump/motor assembly. A method for determining the absolute component position is also set forth.
Abstract:
Improvement, in hydraulic systems, such as for vehicle transmissions and the like, in the form of a hydraulic reservoir with integrated heat exchanger having fluid supply/return and fluid return ports, including a central section, having inner and outer shell portions with a first gap therebetween, the outer shell being provided with a plurality of radially-spaced, external cooling fins, longitudinally-directed for the length of the central section; the ends of the latter being closed off via respective bottom and top cap portions, thereby defining a central fluid cavity, the top cap portion having spaced outer and inner cap portions, with a second gap therebetween, with a fluid inlet port, in the outer cap portion, directing incoming fluid from the second gap into and through the entire length of the first gap before entering the central fluid cavity, thereby maximizing heat transfer from the fluid via the plurality of cooling fins.
Abstract:
A Bulk Mail Container (BMC) unloader uses a simple crossed four bar-linkage to move a predetermined point on a BMC unloader in a substantially straight line while the overall BMC unloader rotates about that predetermined point so as to upend the BMC container. This takes advantage of the crossed four-bar's substantially straight-line motion over a limited range of its motion, as well as the rotational motion of the particular unloader link disclosed herein. This is advantageous for unloading. In use, a BMC container is simply rolled into the BMC unloader, and the entire combination of the BMC container and BMC unloader is then actuated to produce substantially straight line motion along a suitably selected “center” point of the BMC unloader while the overall combination rotates about the center point so as to upend the BMC for unloading.
Abstract:
Methods and assays are provided for isolating factors including polypeptides, ribonucleic acids (RNAs) and polypeptide complexes that are associated with a target nucleic acid sequence. The target nucleic acid sequence may be comprised within chromatin. The methods are suitable for identification and characterisation of factors including non-coding RNAs (ncRNAs) that associate with specified genomic loci.
Abstract:
A location database is maintained with information regarding each of a number of different geographical items in different locations. A user database is also maintained with user records for various users, each user record comprising the user's identification data. In addition, in at least one of the location database and the user database, an identification is maintained of different geographical items which each user has visited. Geographical-item-to-geographical-item similarities are defined between different geographical items based on the user database. User-to-user similarities between the users are defined based on the user database. A weighted combination of the defined geographical-item-to-geographical-item and user-to-user similarities is computed and particularly relevant geographical items in a given location are identified to a user based on the weighted combination.
Abstract:
Methods for isolating non-coding nucleic acids that are associated with chromatin at a target genomic locus are provided. The methods comprise the steps of obtaining a sample that comprises a target genomic DNA sequence and one or more non-coding nucleic acids associated with that DNA sequence; contacting the sample with at least one oligonucleotide probe that comprises a sequence that is complimentary to and capable of hybridising with at least a portion of the target DNA sequence, wherein the oligonucleotide probe comprises at least one modified nucleotide analogue and wherein the oligonucleotide probe further comprises at least one affinity label; allowing the at least one oligonucleotide probe and the target DNA sequence to hybridise with each other so as to form a probe-target hybrid; isolating the probe-target hybrid from the sample by immobilizing the probe-target hybrid through a molecule that binds to the at least one affinity label; and eluting the one or more non-coding nucleic acids that are associated with the target genomic DNA sequence. Also provided are probes suitable for use in the methods of the invention. The methods and probes of the invention are suited to identification of non-coding RNAs including microRNAs and snoRNAs that are associated with chromatin remodelling.
