Patent GB-950634-A (GB)
Abstract: 950,634. Aircraft bombsights. FERRANTI Ltd. June 13, 1962 [March 15, 1961], No. 9571/61. Heading F3C. An aircraft bombsight comprises a sighting head including an aiming mark 25<SP>1</SP> which is kept in alignment with the target and a measuring apparatus 42 for continuously driving a smoothed measured quantity dependent upon a characteristic of the aircraft's motion in the pitch plane. A computing apparatus 41 continuously derives a quantity dependent upon the critical value of the characteristic which, when the quantity corresponds to the measured quantity a bomb release apparatus 58 is triggered. The characteristic is the pitch rate of the aircraft or the acceleration of the aircraft perpendicular to the plane of its wings. In the construction shown the sighting head includes a gyroscope assembly similar to that of Specification 578,958, a signal corresponding to a function of the constant angle # between the flight line PS and the sight line PQ being fed in constant push pull to a pair of two pairs of coils 18 to actuate the tilting of the gyroscope axis through inducing eddy currents in a spherical dome 12. The function b . d / v, where b and d are   constants fed manually into computor 31 and v is the velocity of the aircraft is a solution of the equation # = d/v, and d = ¢gT, where T is the predetermined bomb time of flight. If the angle # is large it is multiplied by the factor b so that the small angle approximations may be made. The measuring apparatus 42 includes a gyroscope assembly, the spherial dome 44 of which is actuated by eddy currents induced by a pair of coils 51 and an annular coil 52. The coils 51 are fed from the computer 41 with a signal equivalent to the function g/2v which is the critical value of the pitch rate w of the aircraft. The gyroscope wheel 43 carries a contact 58 which, when the critical value is reached, engages a contact 56 of the bomb release apparatus 58. In a further embodiment (Fig. 3, not shown) the critical value a = g/2, where a is the acceleration of the aircraft perpendicular to the plane of its wings is compared with the smoothed measured value of a. The comparing means may comprise an electromagnetic relay which, when actuated, closes bomb release contacts.

Title: Laser imaging system
Inventor: PASSMORE RAYMOND
IPC: G01S17/34
Filed: 1995-11-08
Abstract: A laser imaging system illuminates a target object (7) with a frequency modulated continuous wave (FMCW) beam of radiation, and generates an intermediate frequency signal by comparing the transmitted signal with a signal reflected from the target by means of combiner (10) and mixer (11). The intermediate frequency signal is filtered by pass band filter (12), the width of the pass band corresponds to the "depth of field" of the viewed scene, and the frequency on which the filter is centred determines the range at which an image is received. Variation of the centre frequency enables the build up of a 3-D image. The system reduces common volume scattering caused by particles in the beam between the imaging system and target object, and is particularly suited to underwater applications when used in conjunction with a pumped frequency doubling system.

Title: Control of fuel-injection timing in a four-stroke spark-ignition four-stroke direct injection i.c. engine with simultaneous ignition in two cylinders
Inventor: AKIMOTO AKIRA
IPC: F02D41/34
Filed: 1996-06-21
Abstract: A single ignition coil is provided per two cylinders whose phase difference is 360 degrees so that simultaneous ignition occurs in one cylinder (the firing cylinder) near the end of the compression stroke) and in the other (the off-firing cylinder) near the end of the exhaust stroke. To prevent preignition in the off-firing cylinder, the combustion control system judges whether or not the spark discharge period (SPT) overlaps with the fuel injection period (Ti). If it is judged not to overlap, the fuel injection starting timing determined based on the engine speed (Ne) and the fuel injection amount (GF) is allowed to be a final fuel injection starting timing. If it is judged to overlap, the spark discharge ending timing (SPE) is obtained from the ignition timing (ADVF) and the spark discharge period (SPT) and this spark discharge ending timing is allowed to be a final fuel injection starting timing. Alternatively, a "preignition period" is determined based on experimental results and the injection is delayed if it would occur during this period. The fuel injection starting timing is thus delayed to prevent the off-firing cylinder from being fired.

Title: Test circuit for a semiconductor memory device
Inventor: YOO JEI-HWAN
IPC: G11C29/00
Filed: 1996-09-16
Abstract: A semiconductor memory device is tested by sequentially coupling a plurality of global input/output lines to a comparator which compares data bits from the global input/output lines sequentially rather than in parallel so as to reduce the number of output sense amplifiers. This reduces both the chip area, and the excessive current consumption caused by large numbers of sense amplifiers operating in parallel. The memory device includes a plurality of global input/output lines coupled to a memory cell array to receive data from the memory cell array. A global line select circuit generates sequential global line select signals during a test operation. A plurality of switch circuits selectively couples data from the global input/output lines to a sense amplifier responsive to the global line select signals. A comparator coupled to the output port of the sense amplifier sequentially compares a sequence of test data output from the sense amplifier and generates a result signal during the test operation.

Title: Electrically operated pressure-modulating valve
Inventor: CASAS RIBES XAVIER
IPC: F16K31/40
Filed: 1997-09-25
Abstract: The present invention concerns an electrically operated pressure modulating valve characterized by being composed of a magnetic circuit and a pneumatic system separated from each other, the magnetic circuit having various gaps (5) in which there is no good magnetic conductor, thus causing flux saturations in the whole circuit along which the magnetic flux must pass, with the result that the force-intensity curve obtained is a substantially straight line, regulation (6) in this magnetic circuit being accomplished by reducing the gap between the fixed core (2) and the moving core (4), for example by means of a screw-thread on the fixed core (2), providing adjustment between the necessary regulation values, the moving core (4) being made of a material that is a poor magnetic conductor able to cause a further saturation in the circuit, so that when this moving core is attracted by the fixed core (2), it butts against a separator (7) made of an amagnetic material which has a variable closing diameter, providing different slopes of the force-intensity curve and allowing regulation to be carried out exactly; the pneumatic system comprising three chambers (8), (9) and (10), two of which chambers (8) and (9) being connected together through holes (12) in an element which secures the entire shut-off mechanism (17), whereas the third chamber (10) is linked through a small hole (13), which minimizes the pressure loss and the consumption of the electric valve.

Title: Hydroforming apparatus having in-die piercing capabilities and slug ejection using hydroforming fluid
Inventor: MARANDO RICHARD ANTHONY
IPC: B21D26/02
Filed: 1997-11-25
Abstract: A hydroforming apparatus (10) having in-die hole piercing capabilities and a slug ejection system is disclosed. The slug ejection system uses the pressurized hydroforming fluid as the motive force to eject the slug of material created by the in-die hole piercing system. The in-die hole piercing system includes a movable punch (50) disposed within a bore (48) formed in one of the die blocks (22). The bore (48) opens into the die cavity (26). The punch (50) includes a cutting edge on a first end (52) which is adjacent the cavity (26). The hole is formed when the punch (50) is inserted against a hollow workpiece positioned in the apparatus, thereby creating a slug of material. The slug ejection system includes two passageways (62, 64) formed internally to the same die block (22) having the in-die hole piercing system. Both passageways open into and extend in a generally transverse direction to the bore (48). A first passageway (62) is in fluid communication with the source of the hydroforming fluid. A second passageway (64) is located generally opposite the first passageway (62) and functions as a chute to catch the slug of material ejected by the hydroforming fluid supplied to the first passageway (62). The hydroforming fluid is supplied to the first passageway only after the workpiece has been hydroformed and remains pressurized and the punch (50) is retracted to a position where it is generally aligned with both passageways (62, 64).

Title: Recirculating ball bearing
Inventor: VELDE HENRYK
IPC: F16C29/08
Filed: 1998-02-06
Abstract: A cage 1 for a recirculating ball bearing for longitudinal movement along a shaft has a plurality of raceways 6, 8 with a similar cross-section which can retain radially outer race elements 16 inserted into the cage 1. The race elements 16 are inserted into radially outer openings of the forward tracks 6 and bear the load applied to the balls 7. Both the forward and return tracks 6, 8 may be at the same radius from the centre of the shaft and can have the same cross-section after initial manufacture. Thus, depending upon the arrangement of forward and return tracks required, any of the tracks can have its radially outer segment removed to form the opening for a race element 16 and become a forward track 6. External lines of fracture on the cage blank may indicate where the tracks 6, 8 are located. The same cage blank can thus accommodated for various race elements 16 of different dimensions. The race elements 16 may be steel.
