Title: Sieve mat
Inventor: BROUGH STEVEN PETER
IPC: B08B17/00
Filed: 2009-05-07
Abstract: Mat 1 comprises a sheet of material 2 at least a proportion of which is cleaning liquid permeable but having a hole size small enough to retain soil particles. An upstand, such as provided by sleeves and poles 3A,3B,3C,3D and 4A,4B,4C,4D,is provided around substantially all the perimeter of the sheet of material. Sheet of material 2 is large enough to accommodate a bicycle or motorcycle. In use such a bicycle or motorcycle can be positioned on the mat and washed down with cleaning liquid, with the sheet of material 2 allowing the cleaning liquid through it but retaining any soil particles and debris. The mat 1 is preferably a sheet of woven polypropylene and the upstand may be inflatable.

Title: Method and apparatus for generalized performance evaluation of equipment using achievable performance derived from statistics and real-time data
Inventor: FRANCINO PETER N
IPC: F23N5/26
Filed: 2008-03-12
Abstract: A statistical performance evaluation system for a thermodynamic device and process uses the achievable performance derived from statistics and real-time data for the device or process to evaluate the current performance of the device or process, and to adjust the operations of the device or process accordingly, or provide feedback to an operator or other monitoring system for taking corrective actions to obtain performance approaching the optimum achievable performance. The achievable performance of the device or process is derived from data collected during operational periods when the best achievable performance is anticipated, such as after maintenance is performed, and supersedes the ideal or design performance specified by the manufacturer, which typically does not represent the actual operating conditions in the field, as the basis for evaluating the real-time performance of the device. The statistical performance evaluation system may set desired upper and lower limits for performance parameters, and compare desired limits to the actual performance parameter values to determine the readjustment to be made to the operation of the device or process.
Patent GB-2469153-A (GB)
Title: A power splitter and rectifier for providing DC bias to an upconverting parametric amplifier in an mri system
Inventor: VESTER MARKUS
IPC: G01R33/36
Filed: 2009-09-08
Abstract: DC bias 22 for an upconverting parametric amplifier 35 is produced by a rectifier 43 fed from a power splitter 44 which passes fractions of the incident local oscillator (pump) power signal 7 to the rectifier 43 and the parametric amplifier 35. When a bias signal is not present the amplifier is detuned and its low output impedance in this detuned state would tend to reduce the level of the local oscillator signal at the rectifier 43, locking the circuit into a non-working state. This problem can be overcome without the use of a self-start circuit by using a power splitter 44 to ensure that sufficient local oscillator power is provided to the rectifier 43 even when the amplifier is detuned. The power splitter 44 may be Wilkinson divider or a directional coupler.

Title: Wheelchair access ramp with pivoted flaps forming a window to improve rear view visibility
Inventor: GREENWOOD STEPHEN
IPC: A61G3/06
Filed: 2009-12-18
Abstract: A two-part folding vehicle access ramp includes a pair of pivoted flaps 123,125 which are arranged to create a window 160 in the ramp when the ramp is in a stowed position. The ramp comprises first and second ramp parts 122,124 which are pivotally coupled 126,127 to one another, with each ramp part including a cut out having a flap 123,125 pivotally mounted therein. The two flaps are also pivotally coupled 150 to one another and arranged such that when the first and second ramp parts move from a ramp position to a vertical stowed position, as shown in Fig 7, they move automatically to a lowered position so that a driver can see rearwardly through the cut outs. Support legs 140 and abutment means 130 may be used to lock the flaps within the cut-outs when the ramped is lowered for use. Also disclosed is a method of automatically deploying or retracting the ramp, and a vehicle fitted with the access ramp. The flaps are used to create a window in the ramp to improve the driver's rear view.

The hot gas is not cooled, or only slightly, e.g. from 1250‹ to 1000‹ C., before the solids are removed.

Abstract: 1,210,105. Evaporation of liquid from sludges and solutions. H. KOHLMANN. 5 March, 1968, No. 10583/68. Heading B1B. Clarification sludge is thickened, or a solution is concentrated, by pumping the sludge or solution through conduit. 2 and pipe coil 4 where the fluid is heated so that its viscosity is considerably reduced, and passing the hot fluid through throttle valve 6 into a vessel 5 maintained at lower pressure, wherein part of the carrier liquid (water) vaporizes. Some of the sludge or solution, collected in the lower part of vessel 5, is recycled to coil 4, the remainder being transferred by pump 7 to an evaporator wherein the material is moved down over a series of heated trays by scrapers 14 rotating on shaft 15. Thickened sludge, or concentrated -solution; is discharged from the apparatus by rotating worm 18. The trays are heated by process vapour (steam) conveyed from flash vessel 5 by conduit 8. The vapour evolved in the tray-type evaporator may be passed by blower 21 to a feed preheater (not shown). The liquid level in flash chamber 5 is maintained between levels 23 and 24, e.g. by floats; and two rotation speeds are provided for the drive of feed pump 1. The heating surface of each tray may be formed by tubes 10 of square cross-section fitted into one another, the cavities of which are in communication for the passage of the heating vapour. Alternatively, tubes of triangular cross-section may be fitted side by side, with apices upwards.
