Title: Container for storing and dispensing a liquid
Inventor: TOMLIN MATTHEW
IPC: B41J2/175
Filed: 2014-08-14
Abstract: A container (2, Fig.3) for storing and dispensing a liquid comprises a chamber for holding a liquid, the chamber being defined by rigid chamber walls (4, Fig.3); a liquid outlet port (10, Fig.3) for dispensing the liquid from the chamber; and a gas port 20 configured to allow air into the chamber from the atmosphere outside the chamber only when the pressure outside the chamber exceeds the pressure inside the chamber by more than a predetermined threshold. When liquid is dispensed from the container via its outlet port, the pressure within the chamber will be reduced. When the pressure within the chamber falls below the external, ambient pressure by more than a predetermined amount, the gas port will open to allow air into the chamber from the atmosphere. This allows liquid to continue to be withdrawn readily from the container, by preventing a significant pressure differential from building up between the inside and outside of the chamber. The gas port 20 may comprise a non-return valve which may be a duckbill valve 22 made from EPDM rubber or a perfluoroelastomer material. The non-return valve may be integrally formed with a pressure relief valve such as an umbrella valve (70, Fig.7).

Title: Connector assembly
Inventor: GARETH JOHN EDWARDS
IPC: B65D41/04
Filed: 2014-11-03
Abstract: A connector assembly is described for providing a mechanical engagement between a cylindrical component A and a second component B, at least part of which extends around the outside of the cylindrical component. The connector comprises: a groove E in and extending around an outer surface of the cylindrical component; a ring D provided within the groove and projecting out beyond the outer surface of the cylindrical component; a first engagement surface G of the second component for contacting a first projecting part of the ring; and an annular component extending around the outside of the cylindrical component and carrying a second engagement surface J for contacting a second projecting part of the ring. The annular component is movably mounted to the second component so that as it is moved towards the second component the ring is trapped between the first engagement surface, the second engagement surface and the inside of the groove. Axial movement between the cylindrical component and the second component may thus be constrained by the engagement of the ring with each of the groove, the first engagement surface and the second engagement surface. The connector may be used for purposes such as connecting a base or lid to a cylindrical container or housing.

Title: Pressure exchanger system with a vessel elongation absorber
Inventor: HENRIKH ROJANSKIY
IPC: F16L51/00
Filed: 2014-11-25
Abstract: A pressure exchanger system comprises at least one pair of pressure vessels (Fig 2, 101a, 101b), each vessel having a feed side and a brine side, and each side having an inlet port and an outlet port for directing fluid into and out of the pressure vessel. The pressure exchanger system also includes a valve system adapted to direct brine or feed fluid into an out of the pressure vessels at predetermined pressures and an elongation absorber device (50) having a housing element (70) configured for connection to a pressure vessel support and an inner element (60) for connection to a high pressure feed check valve outlet. The inner element is slidable with respect to the housing element in response to length changes of the pressure vessel. Advantageously the sliding movements between the inner element and the housing element of the elongation absorber device allows axial length changes of a pressure vessel with high frequency cycles and avoids mechanical loads and stresses within its piping system and hence avoids associated fatigue failures.

Title: Progress and Attainment Assessment System and Method
Inventor: JAMES LEEDS
IPC: G06Q50/20
Filed: 2015-07-29
Abstract: A method for comparing a characteristic of a set of developing entities comprises; following an assessment of a characteristic at a particular development stage, recording a discrete grade of each entity; converting each grade to a normalised value by means of a conversion function; and calculating an average of the normalised values. This average value is then compared to a normalised value of an acceptable grade for that development stage, resulting in a difference value being evaluated and outputted. Alternatively, the average value is compared to the average of normalised values corresponding to grades of the same set of entities at a second later development stage, leading to another difference value being evaluated and outputted. In particular, the entities may be students, where the characteristic is ability in an academic subject and the grades are those achieved in a subject after a test or an exam. The normalised values might be in a universal scale composed of numerical identifiers. This method compares the attainment or progress of a group of students against an acceptable level or against an earlier level achieved by the same students, and the normalised values allow comparison even if different grading systems are used.

Abstract: A data buffer or memory cache device (including a method of use) comprising a data storage circuitry 20 ; input circuitry 30,52 to input data WDATA to be stored by the data storage circuitry20 at a first operating voltage VL; output circuitry 40, 52 to output stored data from the data storage circuitry at a second operating voltage VH different to the first operating voltage; and control circuitry 52,232, 242, 200, 210 to control an operating voltage of the data storage circuitry to be substantially the first operating voltage (VL) during a data input (write) operation by the input circuitry and to be substantially the second operating voltage (VH) during a data output operation by the output circuitry 40. The control circuitry may provide input or output enable signals when the input/output circuitry respectively are ready to handle data, in which case separate (first, second) voltage control signals may also be issued to action the two separate voltage sources. The control circuitry may comprise a delay circuit to individually delay the first 54 and second 56 voltage control signals. The second voltage control signal is preferably issued by the controller on completion of a successful data input operation. Likewise on receipt of a completed data output operation a first voltage control signal is preferably issued. The control circuitry may be configured to inhibit voltage changes if the first and second operating voltages differ by less than a threshold amount. Preferably the input and output circuits will operate at the first operating voltage during a data input and on the second operating voltage on a data output operation. Clamps may be used to separately set the voltage of the input and output circuits to alternative predetermined voltages when either is not ready. Embodiments disclosed comprise a second data storage circuitry, second input and output circuitry which now operate at the second and first voltages respectively (or vice versa). The control circuitry may comprise power gating switches (e.g PMOSFET devices) to enable the connection of the respective power supply inputs. The data storage circuit may be a flip-flop register or SRAM (static RAM) array.

Title: Subterranean solids separator
Inventor: CALVIN J STOWE
IPC: E21B27/00
Filed: 2014-09-22
Abstract: A debris removal device for subterranean use features a debris laden inlet tube within a housing to define a debris collection space at the lower end of the housing. An eductor draws the debris laden fluid to the top of the inlet tube where the flow stream is returned to a downhole direction with discrete passages formed between the housing and the inlet tube by spaced parallel plates. The plates feature extending tabs on diametrically opposed lower ends of the plates. As a result flow heading back downhole can release debris and turn back uphole in passages defined between the outside of the plates and the inside wall of the housing. The tabs allow the flow turning uphole to make a greater radius turn because of a crossing over effect created by the tabs. There is less turbulence and narrower width to the flowing stream going uphole.

Title: Method of creating a data chain in a data structure that can be cryptographically proven to contain valid data
Inventor: DAVID IRVINE
IPC: G06F21/64
Filed: 2016-05-23
Abstract: This application is for a method of creating a data chain on a network that is cryptographically validated in order to overcome problems with the prior art. It works by first creating a data chain that contains no elements 202, then validating the data chain by the nodes in the network before accepting it 204. It then verifies a size of a close, or secure, group to add to the data chain 206. It then adds a block of data to the data chain 208 and ensures that new elements, or links, are injected into the chain that represent the current close, or secure, group of data elements 210. It then validates a majority of pre-existing nodes in the network 216 and validates a signature of the data chain using the data chain of previously signed elements 218. It can also remove old copies of entries from the data chain only if a chained consensus would not be broken, otherwise it marks it as deleted.
