Title: Warning system for tactical aircraft
Inventor: PATERSON NOEL S
IPC: G01P1/08
Filed: 1984-05-09
Abstract: A system for warning the pilot of a tactical aircraft in a tactical maneuver such as a dive of the point at which recovery must be immediately initiated to prevent the aircraft from descending below a minimum desired altitude monitors the altitude, descent rate and pitch angle of the aircraft, and issues a voice warning when recovery must be initiated. The system also provides warnings of dangerous flight conditions during non-tactical or common route segments of a flight such as the take-off, landing and cruise segments of a flight. Circuitry responsive to the arming of the weapons of the aircraft enables the tactical warning portion of the system and disables certain functions of the non-tactical portion of the system that may cause false warnings to be generated during tactical maneuvers. <IMAGE>

Title: Data compression
Inventor: HUMBLET PIERRE A
IPC: H03M7/42
Filed: 1985-01-30
Abstract: A stream of source characters, each having a time-varying frequency of appearance, is encoded into a stream of codewords. A rank store stores the rank corresponding to the current estimated relative frequency of appearance of each of the source characters in the stream. A rank updater exchanges the rank of each of the source characters which appear in the stream with the rank of the next lower ranking one of the source characters unless the source character in question has the lowest possible rank.
Patent GB-2159010-A (GB)
Title: Protecting alternators in electricity supply systems
Inventor: WARIN JOHN WILLIAM
IPC: H02H3/46
Filed: 1985-04-26
Abstract: In alternator systems connected to a grid, it is necessary to detect disconnection of the grid supply therefrom and, in that event, to isolate the alternator system from the grid. The frequency of the electricity in the grid changes slowly and, as the alternator system is in synchronism with the grid supply, changes in the alternator systems frequency are dictated by the grid supply. In the event of a disconnection, however, the changes of frequency in the alternator system occur relatively rapidly. Consequently, the alternator system is operated such that it is isolated from the grid if a current signal of a repeatedly updated signal indicative of rate of change of frequency of the electricity generated by the alternator is outside a predetermined acceptance band. During each positive half cycle of one phase of the alternator supply a counter 30, counted pulses from a 2 MHz oscillator 28, counts up to 2<14> then sets a bistable 34 ON which locks counter 30 into a reset state and releases a counter 32, which counts up to 2<14> during each negative half cycle then resets bistable 34 to OFF. Thus ON and OFF state of the bistable 34 corresponds to the alternator half cycles but are delayed by a certain amount, whereby transients are not counted by a counter 12. A counter 16 counts pulses from an 18kHz oscillator 14. For every 10 cycles counted by counter 12 a store 18 is indexed, whereupon counter 16 is stopped, the oldest count in store 18 is discarded, the remaining counts shifted, and the current figure in counter 16 is introduced into store 18; the counter 16 is then restarted. The counts in store 18 are processed in circuit 20 to give a signal indicative of the rate of change of frequency of the alternator. <IMAGE>

Title: Apparatus and process for deburring unfired ceramic blanks

IPC: B28B11/18
Filed: 1985-08-20
Abstract: The apparatus comprises electronic storage, computer and control means and accommodating means (30) to accommodate a ceramic blank to be deburred. The apparatus includes means for rigidly connecting an elongate non-rotary deburring tool (27) to a force sensor (24) and means either for displacing, or for tilting, the longitudinal axis of the tool (27) to a point on the blank (33) to be deburred. The displacing means enable the displacment along the straight lines not parallel to one another and which are not situated in the tangential plane but which are parallel to the tangential plane, or the tilting means are such that the said two straight lines constitute axes (20,22) for tilting movements. <IMAGE>

Title: Compensation for parasitic capacitances in a screened resistance device
Inventor: GATERMANN WILLI
IPC: G01R15/04
Filed: 1985-12-12
Abstract: In a method of compensating for parasitic capacitances between a resistor (R3) and an electrically conducting screening electrode (4), e.g. in a potential divider arrangement (R3/R4) for measuring a high voltage (UH) having alternating voltage, there is used an additional electrode (5) which extends around the resistor (R3) and has the form of a semi-cylinder produced from a right-angled triangular sheet of electrically conductive material. The part of the current which flows away from the resistor (R3) due to the alternating voltage between the resistor and the screening electrode, or to the parasitic capacitances, is thus prevented. The other part of this current is replaced through a countercurrent of equal magnitude counteracting the current flowing away. <IMAGE>

Title: Device for clamping tools to a tool holder of a machine-tool

Filed: 1986-05-06
Abstract: A cutting tool head 2 is clamped to a tool holder of a machine tool by means of an axial drawing element, such as a tension bolt 5, which extends through the tool holder 1 into engagement with the tool head 2. The tool head 2 is centered and positioned axially with respect to the tool holder 1 by interengagement between short frusto-conical surfaces 1b and 2b on the holder and tool head respectively, and simultaneous interengagement between axial stop surfaces 1a and 2a extending radially from the wider ends of the frusto-conical surfaces 1b,2b respectively. Relative rotation between the tool head 2 and the holder 1 is prevented by engagement of a tongue 4 fixed to the holder 1 and engaging in a radial groove in the tool head 2. <IMAGE>

Patent GB-2193366-A (GB)
Title: Display device
Inventor: YUEN GREGORY WENG MUN
IPC: G09G3/36
Filed: 1986-11-27
Abstract: A drive circuit for a liquid crystal display uses a sampling technique to derive drive signals from a pair of input waveforms VCC, VEE. The waveforms comprise positive going and negative going trapezoidal pulses. By sampling the waveforms VCC, VEE at appropriate points, single cycle AC signals and zero voltage signals can be provided. The technique subjects the drive circuit to a voltage stress that is lower than that provided by conventional techniques. As the waveforms VCC, VEE derived from a power supply are selectively sampled, the maximum voltage applied to a driver circuit is one half instead of the full peak to peak voltage. The driver stage may include two switches connected in cascade. Operation of the power supply and the row, column drivers is controlled in response to input data signals via a control circuit. The liquid crystal is of the scattering type and the display device may be incorporated in a facsimile machine. <IMAGE>
