Patent GB-2221575-A (GB)
Title: Laminated magnetic cores
Inventor: YUKI NORIO
IPC: H01F41/02
Filed: 1989-08-03
Abstract: The core is made from sheets 1 which are laminated together with a sheet-to-sheet distance of 2 to 10 mu m, desirably 3 to 6  mu m and at least a part of the opposed, rough surfaces of the sheets are diffusion-bonded to each other. The laminated magnetic core may have voids present at the diffusion-bonded interface between the adjacent thin sheets. A block of a given shape is punched from the laminated and adhesively bonded core-forming sheets by a press. The block is then magnetically annealed while decomposing and vaporizing the organic adhesive to effect diffusion-bonds 4 at the interface between adjacent sheets of the block leaving voids at the interface between the sheets to maintain the insulation between the sheets.

Title: Electrical capacitors protected against over-pressure
Inventor: SNOWDON DAVID R
IPC: H01G2/14
Filed: 1989-11-10
Abstract: A capacitor is composed of a casing (4) containing a capacitor element (1) connected with conductors (6, 7) to terminals (21, 22) on a sealed cover (20). Weakened zones (36) of the conductors (6, 7) act as a cut-out device and are designed to fracture if the pressure rises in the casing (4) and causes an upper region of the casing (4) to deform. To optimise the response of the cut-out device the majority of the casing interior is filled with a particulate electrically insulating material (45).

Title: Device for taking samples from a liquid
Inventor: ZEH HORST
IPC: G01N1/20
Filed: 1990-03-09
Abstract: A sampling device for taking samples of solids-containing radio-active and/or toxic suspensions circulating in a loop of piping (16, 17) has a single needle head (33). The liquid is drawn off into a sample bottle (20), the liquid being propelled by a vacuum-assisted air lift. In order to minimise the risk of clogging in such a sampling device and to be able to obtain reliably representative samples, the one-needle head (33) comprises a mixing chamber (41) which widens out conically to the inside of the housing of the sampling device (13). A feed line (16) extends into the conical mixing chamber (41) to a position adjacent a needle opening in an end wall (45). The open end of the feed line (16) has a larger diameter than the inside diameter of a sampling needle (31) disposed in the needle head (33) to achieve higher flow velocity and a high degree of turbulence in the liquid in the sampling device. …<IMAGE>…

Title: Control of combustion-induced instabilities
Inventor: GULATI ANIL
IPC: F23M20/00
Filed: 1990-12-19
Abstract: An active control for controlling combustion induced instabilities in a combustion chamber (17) e.g. of a turbine with combustor fuel nozzles for providing fuel in the combustion chamber is provided. The active control includes a pressure transducer (43) for measuring pressure fluctuations in the combustion chamber and a servovalve (53) for modulating the amount of fuel supplied to the fuel nozzles. A phase shifter (47) coupled between the pressure transducer and the servovalve is adjusted so that the amount of fuel supplied for combustion is reduced during pressure peaks. This results in a sufficient phase shift between the fuel flow and unsteady pressure fluctuations. In a second embodiment a similar arrangement is also used to control instabilities in an afterburner (23) by modulating fuel flow to the spray bars (27) as described above. <IMAGE>
Patent GB-906653-A (GB)
IPC: F02K1/17
Abstract: 906,653. Automatic control of gas turbines. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Jan. 7, 1960 [Jan. 8, 1959], No. 739/59. Class 38 (4). [Also in Group XXIX] In a control system for a gas turbine jetpropulsion engine of the single-spool non-reheat type having an air intake designed to receive an air flow at supersonic velocity, the propulsive thrust is controlled by an open loop system varying the area of a jet nozzle, and a closed loop system controls the fuel supply to a combustion system to maintain the engine rotational speed constant. As shown, the speed N of a jet-engine 14 is controlled by varying the fuel delivery QF from a pump assembly 16 driven in response to the output #N of an error box 17 deriving the difference between a signal representative of the actual speed N and a reference signal NR from a selector switch 32. The signal selected by the arm 33 can be of fixed value NR1-NR4 so that the engine speed is maintained constant at a desired value or a value NR from a function generator 31 responsive to the compressor inlet temperature T1 such that up to a limiting value of the ratio N/#T the engine speed is maintained constant and beyond this limit the speed is varied to maintain the ratio constant. When a switch 36 is in the position shown, the limit switch 12 is supplied with a signal from a function generator 15 proportional to the inlet temperature T1 such that for any given value of the temperature T1 there is a limiting minimum valve of the jet nozzle area. The switch 34 is interlocked with the selector switch 32 so that under conditions of run-up or run-down a signal As* proportional to the acceptable minimum value of jet-nozzle area is selected. The pump assembly 16 is further responsive to the compressor inlet pressure P1 to vary fuel delivery with altitude. A signal proportional to flight Mach number M# is fed to a function generator 36 generating a signal which is fed to a mechanism controlling the configuration of an air intake 37 so that the intake area/throat area ratio or the spill ports opening is matched to Moo. In a modification, a change-over switch is automatically actuated by the N/#T signal to change-over the control of the pump assembly from maintaining constant speed to maintaining constant N/#T. The compressor inlet temperature T1 is sensed by a thermocouple. Specifications 759,261 and 788,359 are referred to.
