Patent GB-2201039-A (GB)
Title: A solenoid valve for a fuel injection pump of an internal combustion engine
Inventor: RODRIGUEZ-AMAYA NESTOR
IPC: H01F3/02
Filed: 1988-02-11
Abstract: In order to obtain extremely short valve switching times, at least a part of the magnetic circuit of the electromagnet 19 is laminated in that it comprises a plurality of thin sheet metal layers, which extend in the direction of magnetic flux therein, are contiguous one another and are electrically insulated with respect to one another. Lamination is preferably restricted to the magnet pot 23 which forms the magnet core and the yoke for completing the magnetic path. The laminations comprise wedge shaped segments or planar sheets and reduce the effect of eddy currents. <IMAGE>
Patent GB-2207822-A (GB)
Title: Indicator lamp system
Inventor: HANNA R SCOTT
IPC: B60Q3/04
Filed: 1988-04-29
Abstract: An indicator lamp L1 is dim or bright when a load is off or on respectively. The lamp may flash when the system is receiving a remote control signal (Fig. 9). A break in the load circuit may cause the lamp to be off or flashing, regardless of the load switch state. Alternatively, a load circuit break can cause the lamp to be off if the switch is "off", with full light in the "on" position (Fig. 8). The load may be a lighting system turned on and off by a triac Q1 controlled by contacts of a bistable latching relay. Momentary closure of a switch SW1 discharges a capacitor C3 through relay coil 10A to toggle the relay contacts between states. The contacts cause capacitor C3 to be charged with one polarity when triac Q1 is off and with opposite polarity when triac Q1 is on. A transistor Q2 connects resistors Ra, Rb in parallel to brighten LED L1. Control and load terminals C, SH may be connected to the indicator lamp via a diode bridge having a resistor in one arm to establish the dim indication (Figs. 5, 8). The indicator lamp may shine through a control slider of a dimmer for the main lighting system (Fig.2). <IMAGE>

Patent GB-2226464-A (GB)
Title: Power control apparatus
Inventor: NAKAYAMA KATSUTOYO
IPC: H01H89/06
Filed: 1989-11-15
Abstract: Current flowing in each phase of a main circuit (201) is detected by a current transformer (202) and a zero-phase current transformer (203). Values of these currents are provided to a CPU included in an intelligent controller (207). A maximum peak value and the like are evaluated by the CPU to be compared with predetermined set values. If those values are equal to or higher than the set values, an excitation signal is applied to a tripping device (205) to release a latch (206) and thus to trip the circuit breaker (204). The CPU alters the set value when supplied with a setting alteration instruction from a central monitor (40), and causes the circuit breaker to be tripped when supplied with a stop instruction therefrom. The controller (207) also includes a display which indicates at least the actual and set threshold values of the current. …<IMAGE>…

Title: Determining and extrapolating oil reservoir performance
Inventor: HINCHMAN STEVEN B
IPC: E21B49/00
Filed: 1989-11-27
Abstract: A method of determining a numerical index from a cored well that corresponds to the performance data of the well, and a method of extrapolating the performance of a small area of a reservoir to the entire reservoir through use of the numerical index. Selected variables which affect fluid flow in the reservoir are compared by a statistical analysis computer program to performance data of the computer simulated small reservoir area after both the data and variables have been normalized to dimensionless values. The resulting numerical index is computed for the cored wells both inside and outside the small reservoir area, and a contour or iso-index map is drawn. Well performance outside the simulated area can be compared to expected performance through the numerical index values. <IMAGE>

Title: Apparatus and method for determining powder characteristics
Inventor: MAHGEREFTEH HAROUN
IPC: G01N9/00
Filed: 1990-02-13
Abstract: The application describes a particle sizer comprising a cantilever at which free end is mounted a container partly filled with the powder under test. The mean particle size is determined by setting the system into oscillatory motion and measuring the mass of the powder sample from the resonant frequency and hence relating the resonant amplitude of vibrations to the mean particle size using a previously obtained calibration curve for the same mass of powder. Alternatively, the mean particle size may be determined by measuring the vibrational characteristics of the vibrating system during free vibrations from resonance following excitation shut-off.

Title: Pattern-adaptive digital comb filter for separating luminance and color video signals
Inventor: KIM JUNG HUN
IPC: H03H17/00
Filed: 1991-06-28
Abstract: A digital comb filter circuit which separates digital luminance and color signal components of a video signal adaptively selects 30 1H-comb filtered video signal I1 from subtractor 13 or I2 from subtractor 14 or 2H-comb filtered video signal 10 from adder 17 according to the correlation 20 between upper and lower horizontal scanning lines of the three successive horizontal lines used in the comb filtering. A comb filtering controller 40 compares the correlation data from generator 20 with reference data at input 102 and controls multiplexer 30. However if the video signal is irregular an irregular data signal applied at input 103 causes multiplexer 30 to select a one line delayed video signal 13 for output to circuit 100 i.e. the luminance and colour signals are separated without comb-filtering. <IMAGE>
