Title: Automatic control for a limiting device using duplicated control circuits
Inventor: MORRIS CLIVE ALEXANDER
IPC: G05B9/03
Filed: 1983-07-14
Abstract: A system for generating electrical signals which are intended to control a flow limiting device 13, in particular in a fuel control apparatus 10, 12, has duplicated signal generating circuits 18, 31,which are responsive to operation of the fuel control apparatus 10, 12 and which generate nominally identical output signals when an operating condition NL or NI of the fuel control apparatus 10, 12 exceeds predetermined limits. Output signals from the duplicated circuits 18, 31 are supplied to the limiting device 13 by way of respective control circuits 20, 33 each of which is enabled by the presence of a corresponding output signal from the other of the signal generating circuits 18, 31. Means are provided for detecting a malfunction of one of the signal generating circuits 18 or 31 and for permanently enabling the control circuit 33 or 20 through which output signals from the other of the signal generating circuits 31 or 18 is supplied. <IMAGE>

Title: Board for a jigsaw puzzle
Inventor: KAYE ROBERT NICHOLAS
IPC: A63F9/10
Filed: 1984-01-27
Abstract: A support board for a jigsaw puzzle comprises a base 1 of which the surface 2 is to receive a jigsaw. The base has integral ribs 3 which form feet. The surface of the base receiving the jigsaw may have a strip of baize material 4 secured thereto over the whole area, or may be polished the latter being preferred. Secured to an end 5 of the base is a flexible plastics sheet 6 and this may be retained by a strip 7 attached by rivets 8 or adhesive passing through the strip 7, sheet 6 and through the end of the board 1. The plastics sheet 6 has a flexible magnetic rubber material 9 provided along the three free edges. This material 9 cooperates with a steel strip either inlaid into a recess in or directly on the top surface of the base and when the sheet is placed over the base it is securely held in position and thus traps the jigsaw pieces. Alternatively, interengaging barb/loop fabric fastener or cohesion between the polished surfaces of the sheet and base may be utilised to hold the sheet in position over the base. <IMAGE>

Title: Method of filling a cavity with foamed material
Inventor: WORRICKER JOHN ARTHUR
IPC: F25D23/06
Filed: 1984-04-27
Abstract: In a method of filling a cavity, such as the space between the shell 1 and liner 2 of a refrigerator or freezer, with foamed material, the foam-forming constituents are introduced into the cavity 3 through a tube 5 extending for a distance into the cavity from the point of introduction 4, at least the major part of the tube 5 remaining embedded in the solidified foamed material at the completion of the process.

Title: Improvements in and relating to apparatus for detecting particles in suspension
Inventor: RANK EDMUND MILES
IPC: G01J1/42
Filed: 1985-10-30
Abstract: In a particle dispersion analyser which has a vertical groove to receive a transparent plastics tube 24 through which a liquid to be analysed is caused to flow, light from a light emitting diode 32 is passed through the tube 24 and the liquid flowing in it, and is detected by a cell 36. The d.c. component of the output of the cell 36 is digitised by an ADC 40, and the a.c. component is processed by a circuit 50 to provide a d.c. value equivalent to the a.c. RMS value, which is digitised by a second ADC 52. The ratio between the two digital values is taken as a measure of suspension particle size or degree of emulsification. As described, the tube 24 is clamped in the groove by a spring loaded member 74 which presses it against another member 68. The member 74 carries a sleeve 82 which is also pressed against the further member 68 and which has aligned slits 76, 78 to accommodate the tube 24. Different sleeves 82 having slots of different sizes may be used to adapt the clamping device to tubes 24 of different diameters. The members 68, 74 are opaque and carry respective optical fibres 62, 64, extending from the LED and the detector and terminating in the faces of the members which contact the tube 24. <IMAGE>
Patent GB-2187290-A (GB)
Title: Determining breakdown of liquid samples
Inventor: KEEN ANDREW LEONARD
IPC: G01N27/92
Filed: 1986-01-31
Abstract: In the measurement of the breakdown potential of each of a number of samples of emulsions (eg drilling fluids) a pair of electrodes (10, 11) are emersed in a sample, the potential difference between the electrodes is increased at a uniform rate until the current flow between the electrodes exceeds a threshold value. The peak voltage is then displayed. In the testing of successive samples, the potential difference between the electrodes is increased at the same rate. The applied voltage is generated at 13 in the form of uni-directional voltage pulses of increasing magnitude controlled by ramp generator 15, and is displayed on digital meter 17 which reads up to 2000V. Current flowing through the probe is monitored as voltage across resistor R27 and when this voltage reaches the threshold set for comparator IC4, latch 20 is set, the pulse generator 13 is disabled and, after a short delay the breakdown voltage is indicated on meter 17. <IMAGE>

Patent GB-2291132-A (GB)
Title: Fuel control system
Inventor: SEVERN MICHAEL JOHN
IPC: F02C9/38
Filed: 1986-06-09
Abstract: Fuel for the combustion equipment of the engine of a VTOL aircraft is supplied via pumps 50, 24 through a metering valve 22, which is under the control of a digital electronic control unit (DECU) 10. A pressure drop regulator 30 and spill valve 32 ensure there is a constant pressure drop across the metering valve 22. To provide a rapid reduction in fuel output when the aircraft pilot slams shut his control lever 16 when he touches down after a vertical landing, and therefore prevent the aircraft bouncing, the DECU 10 detects the sudden slamming closed of the lever 16, and opens a solenoid valve 60. Fuel now bleeds along line 58, and the input 54 of the regulator 30 sees an increased pressure drop determined by a potentiometer formed by two flow restricting orifices 56, 62. The regulator 30 therefore opens the spill valve 32 giving the desired rapid reduction in fuel flow through the metering valve 22. <IMAGE>

Title: Sputter ion plating
Inventor: COAD DR JOSEPH PAUL
IPC: C23C14/16
Filed: 1986-06-27
Abstract: A coating of the alloy MCrAlSi (wherein M is one or more of Ni, Co, Fe) is formed on a substrate by sputter ion plating wherein a DC glow discharge is generated under soft vacuum conditions in the presence of the substrate and of a cathode constituted by the coating material thereby to release material at the cathode by ion bombardment, which released material diffuses to the substrate to form the coating thereon, and wherein a potential is applied to the substrate during coating, the potential being in the form of an AC bias in order to control the properties of the coating, using the biasing means in order to densify the coating by resputtering of deposited material and ion polishing. It is thereby possible to coat uniformly substrates having sharp edges such as aerofoil components for a gas turbine engine. As illustrated in the figure the substrate 12 in the earthed coating chamber is connected to a bias potential power supply by a conductor 13 mounted in insulators in the walls of the pumping chamber, and the cathode is in the form of a series of target plates, 16, 17, to which a high negative voltage is supplied, thereby producing a glow discharge. <IMAGE>
