Title: Glowplug power control with a differential equation that is nonlinear in the glowplug temperature
Inventor: CASSANI STEFANO
IPC: F02P19/02
Filed: 2009-08-19
Abstract: Control of power supplied to a compression-ignition engine glowplug 12 involves the prediction of glow plug temperature Tg from values for power supplied to the glowplug Pg and combustion chamber temperature Tcc, with the predicted temperature derived from a numerical solution of a differential equation that is nonlinear in the glowplug temperature Tg. The prediction involves an energy balance, and may be performed in a logic unit (20, fig 1); by an analogue circuit (fig 3); or using look up tables. The predicted value Tg may be compared (step 55, fig 5) to an estimate of the glowplug temperature derived from its resistance to correct drift. The combustion chamber temperature Tcc may be derived from engine load and coolant temperature.

Filed: 2009-11-24
Abstract: The position of one or more constituent elements 606 of a phantom is established in an image quality test for a medical imaging apparatus, such as a PET scanner. An image of the phantom is obtained, and a landmark pixel (302) or region of the image determined. Values of a given variable, such as intensity, at pixels or regions at a predetermined distance from the landmark pixel or region are determined. The landmark pixel or region and the values of the variable are then used to establish the position of one or more of the constituent elements of the phantom. The values may be taken along a line 602 at a predetermined radius from the landmark pixel or region 604 to obtain a sequence of values (706, 708, 804) that are compared to an expected template sequence of values (802) representing a layout of hot and cold spheres 606 of a NEMA image quality test phantom. The landmark pixel may be determined by a minimum or maximum intensity value.

Abstract: 813,337. Assembling torsional vibration dampers. HAUSHALTER, F. L. March 27, 1957, No. 10054/57. Class 108(3) A torsional vibration damper, Fig. 1, is assembled by positioning body member 10, Fig. 2, up against abutment 19 of shaft 18, clamping the radially inner portion of a rubber ring 24 to the rear face of body member 10 adjacent cylindrical surface 14 by clamping device 20, and pushing forward members 11, supported on flange 22, to engage the free portion of ring 24 and fold it over cylindrical surface 14 as member 11 moves up to abutment 19. During this operation the free portion of ring 24, which is thicker than the space between the two members, is stretched so that it is under considerable tension when enclosed in space 17 and thus holds members 10, 11 together. To facilitate this operation a lubricant which is subsequently absorbed by the rubber is used. To prevent buckling of the rubber ring, which is cut from a flat sheet, the outer edge is notched. Projecting pieces of ring are trimmed off after assembly. A second embodiment is described in which the rubber ring is clamped against the outer member and the inner member is pushed in. In this case no notches are required in the rubber ring. In both the above embodiments a rubber ring moulded with an L-shaped cross-section may be raised. In the method shown in Fig. 6, the inner and outer members 28, 31, are held concentrically with an annular space. 33 between them. A rubber ring 44, which is thicker than half the distance between the inner and outer members, is placed over space 33 and pushed into it by steel ring 43 mounted on cup-shaped members 37. When forced in, ring 44, which is notched round its outer edge, is doubled over on itself. A lubricant is used as before and steel ring 43 may be either removed or left in as desired. Specification 813,336 is referred to.

Title: Improvements in or relating to steam generating plant
Inventor: STARMER ROY
IPC: B01D19/00
Filed: 1959-03-24
Abstract: 901,001. Feedwater supply systems. RICHARDSONS, WESTGARTH & CO. Ltd. March 24, 1960 [March 24, 1959], No.10255/59. Class 123 (2). In a feedwater supply system for a boiler 54 the feedwater is thoroughly deaerated by an excess flow of steam, the surplus steam from the deaerator being used as the heating medium in a flash evaporator producing the boiler make-up water. Live steam from the boiler flows through a pipe 60 into the deaeration compartment 30, the excess steam and gases passing therefrom into the heat input section 26 of the evaporator through a pipe 28. A pipe 22 passing through the section 26 conveys saline water which is heated by and condenses the excess steam. The hot saline water passes into the first evaporator flash chamber 12 and cascades through the succeeding chambers. Vapour liberated in each flash chamber rises through a pipe 14 into an associated heating chamber 10, the chambers 10 being traversed by the pipe 22. The vapour condenses in contact with the pipe and the distillate forming the boiler make-up water is withdrawn by a pump 46. Condensate from a condenser 50 is added to the make-up water and flows through a pipe 20 to a feedwater tank 52 whence a pipe 56 conveys the feedwater to the deaerator. A pipe 58 conveys the degassed feedwater to the boiler. The unevaporated saline water is extracted from the last flash chamber by a pump 38, a minor part of the water being blown down at 40 whilst the remainder is recirculated through the pipe 22 with the addition of fresh saline water at 42. As shown by the dotted pipe 62 a deaerator by-pass for part of the steam from the boiler may be provided. In a further modification, a turbine is inserted in the steam pipe 60 from the boiler to the deaerator.

Abstract: 1,270,761. Integrators. FOXBORO CO. 5 March, 1970 [2 June, 1969], No. 10619/70. Heading G4G. Apparatus for integrating a signal having a slowly changing base line-e.g. the chromatograph peak 14, Fig. 3, superimposed upon the tail 12 of a previous peak-includes means for measuring the base line levels g(t 1 ) and g(t 2 ) at the beginning and end of the integration period, and for correcting the result-equal to area (A 2 -A 1 -A 3 )-by adding the triangle (A 1  + A 4  + A 3 ), obtained as half the integral of (g(t 1 )-g(t 2 )) over the time (t2 - t 1 ), to give the required area of the peak (A 2  + A 4 ). The signal g(t) is applied to the integrator formed by amplifier 74, resistor 70, and capacitor 76; at time t 1  switch KD, in a feedback loop 82, is opened to store g(t 1 ) on capacitor 88, and switch KC is closed and KB opened, to initiate integration of (g(t) - g(t 1 )). At time t 2 , switch KC is opened, to store the result of the integration on capacitor 76. Thereafter, switches KE and KF in feedback loop 90 are closed, to drive junction 96 to (g(t 1 -g(t 2 )), which value is stored on capacitor 94 by the subsequent opening of switch KE. The switches are then manipulated to discharge capacitor 88, and to apply a voltage equal or proportional to that on capacitor 94 to the integrator circuit 74, 76 for a period equal or proportional to (t 2 -t 1 ), to correct the signal stored on capacitor 76 for the changing base line. The period equal or proportional to (t 2 -t 1 ) is derived from a ramp generator (Fig. 5, not shown), for which an ascending ramp portion is produced by the application of an input signal for the period (t 2 -t 1 ), and the subsequent descending ramp portion of which controls the period of integration of the quantity (g(t 1 )-g(t 2 )).

Abstract: 375,006. Window blinds. MATRER & PLATT, Ltd. and INCLEDON, C. S. L., Park Works, Manchester. April 15, 1931, No. 11134. [Class 52 (v).] A roller shutter is operated by an electric motor to which it is coupled by a frictional transmission element which is adapted to slip when the shutter reaches the end of its travel in either direction. As shown, the shaft b of an electric motor a is coupled with a shaft j by friction discs e, i, mounted one on each shaft. The shaft j is connected through worm gearing k, or the like, to the shutter. To the shaft b is secured the part c of a dog clutch, the tapered teeth d of which mesh with similar teeth on an element f formed integral with the disc e. The latter is normally pressed into firm contact with the disc i by a spring g one end of which bears against a collar h secured to the shaft b. The increased resistance offered to the disc e by the disc i, when the shutter reaches the end of its travel, causes relative axial movement between the elements of the dog clutch. This movement separates the discs and thereby reduces the power absorbed by the motor. In a modification, the dog clutch and the elements associated therewith are arranged on the shaft j.
