Title: Thrust apparatus
Inventor: WHITFIELD GEORGE WILLIAM
IPC: F03G3/00
Filed: 1990-05-04
Abstract: The apparatus comprises: at last two mass structures 14, 15; 14', 15' driven in rotation about spaced generally parallel axes 4, 5 each of the mass structures being adapted for transition between a balanced state and an unbalanced state during rotation to produce a net thrust R' in a direction transverse to the said axes. Each mass structure comprises a plurality of mass elements 14, 15; 14', 15', and means are provided for varying the angular relationship between the said mass elements so as to achieve the transition between balanced and unbalanced states. In one embodiment the mass elements of each mass structure are driven by a pair of shafts and the angular relationship between each pair of mass elements is varied by adjustment of the relative speeds of the two shafts. In another embodiment (not shown) at least one of the mass elements of each mass structure is magnetically attractive and the means for varying the angular relationship between the mass elements comprises an electromagnet arranged to act on the said mass element to vary its rotational path. <IMAGE>

Title: Low reluctance reed relay
Inventor: WARNER RICHARD JAMES
IPC: H01H51/28
Filed: 1990-05-23
Abstract: In a reed relay having one or more reed contact units 1 surrounded by one or more coils 7, the reluctance of the magnetic circuit is reduced by means of ferrous cheek plates 2 having strips 4 positioned adjacent and parallel to each other over the outside of the coil or coils 7. The magnetic flux flows through the strips 4, thus reducing the electric power required by the coil or coils. The coil 7 may be terminated at 3 on the cheek plate strips 4. <IMAGE>

Title: Apparatus for packaging articles in inert gas
Inventor: SUGA TADORU
IPC: B65B9/067
Filed: 1990-09-26
Abstract: A film web is formed into a tube by a former 11 and, as articles (A) to be packaged are supplied into the formed tube by a conveyor 17, both the tube and articles (A) are advanced while being held between a pair of tension conveyors 13, 14. Double pipes 23, 23 each consisting of an outer evacuation pipe 25 and an inner inert gas jet pipe, 24 extend into the tube, the end of the inner pipe extending beyond the end of the outer pipe by at least a distance corresponding to the length of an article (A). Cushion blocks (26) of soft foam rubber provided in multiplicities on belts 13, 14 exert pressure against the tube from opposite sides thereby to eliminate any superfluous space within the tube and, at same time, to isolate adjacent articles from each other. Thus, the oxygen present in each bag is efficiently displaced by inert gas fed into the bag, and the required inert gas consumption can be minimized. The double pipes are mounted for reciprocable movement in the direction of their lengthwise extent. <IMAGE>

Patent GB-2243015-A (GB)
Title: Magnetic head slider unit
Inventor: TOKUYAMA MIKIO
IPC: G11B5/60
Filed: 1991-01-29
Abstract: A magnetic head slider unit has a slider which is mounted so as to be movable relative to a magnetic medium such as a magnetic disk (100). Contact between the slider (1) and the disk (100) is to be avoided to prevent damage to the disk (100) and therefore the slider (1) is shaped so as to generate an air pressure higher than ambient pressure between itself and the disk (100). A magnetic head (6) for reading and/or writing data to the disk (100) should maintain contact with the disk (100), and is therefore mounted on a movable member (5) movable in a bore (4) in the slider (1). In this way, the head (6) may follow changes in the surface of the disk (100), by movement of the movable member (5) in the bore (4), without inertial forces due to the slider (1) being transmitted to the disk (100). The movable member (5) may be biased towards the disk e.g. a spring (91), or by creating a region of reduced pressure adjacent the movable member (5). Alternatively, the magnetic head may be mounted on a flexible arm (92, 93). <IMAGE>

Title: Metal detector with nulling coil.
Inventor: REGINI ANDREZ ZBIGNIEW
IPC: G01V3/10
Filed: 1991-12-16
Abstract: A metal detector has an AC driven transmission coil 1, a receiving coil 3 which detects the field generated by the transmission coil and a nulling coil 2, adjacent the transmission coil and generating a signal which is equal in magnitude and opposite in direction to the signal produced by the receiving coil in the absence of a metal object. The coils are preferably coaxial and coplanar with the nulling coil 28 receiving coil 3 connected in series opposition. The detector circuit 21 for the difference signal which indicates presence of metal may comprise a variable gain amplifier and a switched feedback path which varies the gain of the amplifier.

Title: Frequency discriminator
Inventor: WARD CHRISTOPHER JOHN
IPC: H03D3/06
Filed: 1992-01-20
Abstract: The frequency discriminator comprises a mixer (10) and a phase shifting circuit (15). An input signal is supplied to first and second input ports (11, 12) of the mixer (10). The phase shifting circuit (15) shifts the phase of the input signal supplied to the second input port (12) by an amount related to the frequency of the input signal. The phase-shifting circuit comprises a resistively driven, parallel resonant circuit (15', 15") connected across the second input port (12) of the mixer (10). The arrangement avoids spurious responses outside the pass band of the tuned circuit (15) by arranging a current to flow into the second part (12) via the tuned circuit so that the discriminator does not fall to zero even at frequencies well beyond the pass band. The mixer (10) may be a Gilbert cell mixer using differential pairs of transistors. <IMAGE>

Title: Recovering refinery petroleum gases
Inventor: CHANG WEI-MIN
IPC: C10G70/04
Filed: 1993-01-25
Abstract: A refinery petroleum gas recovery apparatus driven by waste heat comprises a water cooling system and a heat exchanging petroleum gas recovery system. Waste heat from the refining process in the form of steam is fed to ejectors 3, 4, 5, which are associated with an evaporator 1 so as to create a negative pressure therein by high speed discharge into a condenser 2. As a result of the reduced pressure within the evaporator 1 water passing therethrough is cooled to 12 - 13 DEG C. This cooled water is fed to a heat exchanger 20 for condensing a liquid petroleum gas for reuse. Thus petroleum gases, such as ethane and propane, previously flared off can now be recovered for reuse. <IMAGE>
