Patent GB-2229008-A (GB)
Title: Superconducting fluxgate
Inventor: HILL PETER ERNOLD
IPC: G01R33/035
Filed: 1990-01-12
Abstract: In a superconducting fluxgate arrangement incorporating the Meissner effect, and utilising the principles of current modulation the fluxgate includes a thin layer (2) of a superconducting material such as Yttrium Barium Copper Oxide, the topology of which layer (2) is arranged so as to provide a uniform cross-sectional area parallel to the direction of current flow and a sense coil (4) adjacent layer (2). The drive current IDRIVE may be provided by way of contact strips (3) and in order to provide a uniform current distribution a resistive means providing a profiled connection area may be connected to each contact strip (3). Alternatively the drive current may be induced in layer (2) by a driving winding surrounding the layer and having its axis orthogonal to that of the sense coil (4). <IMAGE>

Title: Fastening mechanism
Inventor: SMITH ROGER MICHAEL
IPC: E05C1/08
Filed: 1990-02-08
Abstract: The fastening mechanism for a sliding panel e.g. a patio door, window has the head of at least one stud automatically trapped in a keyhole slot by actuation of an element 15 during final closing movement of the panel. As shown, the mechanism comprises a lock 1 with a pair of slides 13 formed with respective "keyhole" slots 16 for trapping the heads of fixed studs 10. The slides 13 are biased by springs 14 normally to align the narrower ends of their "keyhole" slots 16 with the studs 10. As the panel is closed, however, a probe 18 on an actuating plate 15 is pressed in to slide the plate rearwards and thereby cam the slides 13 apart, permitting entry of the stud heads through the slots 16. During the final closing movement of the door, the slides 13 are released to spring together once more and thereby trap the studs 10 in their slots 16 (Fig 4). To release the studs from the slots there is another, manually-operable plate 23 for camming the slides 13 apart A key-operable cylinder 29 is provided for blocking the plate 23 and thereby locking the mechanism against release (Figs 6 and 7). In an alternative arrangement (Fig 8) the studs are carried by the slides in the lock while the "keyhole" slots are formed in a fixed keeper plate. <IMAGE>

Patent GB-2232234-A (GB)
Title: Incinerator
Inventor: IIDA ZENICHI
IPC: F23G5/34
Filed: 1990-04-24
Abstract: In order to incinerate waste which contains a large percentage of water and/or sulphur- or chlorine- containing compounds, air and particulate alkali metal or alkaline earth metal minerals are blown into the combustion chamber 1, 2 of an underground incinerator combustion chamber top loaded at 4 the particulate minerals being injected typically at a level 8 above the substantive air inlets 9. The air promotes oxidation of the waste while the particulate matter suspended in the air reacts with and neutralizes the acidic sulphurous and/or hydrochloric matter produced by the oxidation (combustion) process. Exhaust gases at 5 may be filtered at 6 and emitted via stack 7. In the event the waste does not contain much water, the mineral powder can be mixed with water to form a slurry, also injected preferably at level 8. <IMAGE>

Patent GB-2237417-A (GB)
Title: Idle speed control apparatus for internal combustion engine
Inventor: TAKAHASHI MINORU
IPC: F02D41/16
Filed: 1990-08-30
Abstract: When a fluctuation of engine speed (NE) is detected during idling of an engine, an opening degree of a flow control valve provided in an idle bypass pipe is changed at a comparatively large rate of change ( DELTA  D2). When the rate of change of the engine speed ( DELTA  NE) thereafter comes near to zero (t4), it rapidly changes the opening degree to maintain a value ( alpha ) related to intake pipe pressure or an accumulated value of the intake pipe pressure and the engine speed at that point, or until the value is reached at a range which a gentle change is possible. Consequently, for example when the engine speed (NE) drops (t2), the intake air flow is increased at a comparatively large rate of change, and it is possible to prevent engine stalling. Further when the rate of change of the engine speed ( DELTA  NE) passes through zero and begins to rise (t4), the intake air flow (Qin) is rapidly reduced until the value reaches the range at which the torque at that point can be maintained, and so called quick response due to overcontrol is prevented. In this way, with a high control gain, it performs idle speed control having more favorable stability. <IMAGE>

Filed: 1990-09-11
Abstract: In an active back-plane coordinate addressed liquid crystal cell whose pixels are set into one state by the application of a unidirectional potential across the thickness of the liquid crystal layer, and into the opposite state if the direction of the applied potential is reversed, refreshing is carried out in two sequential stages in order to avoid cumulative charge imbalance effects. In one stage the pixels are set to their required states, whereas in the other stage they are set to the inverse of those states.

Patent GB-911110-A (GB)
Abstract: 911,110. Drafting-mechanism. SKF. KUGELLAGERFABRIKEN G.m.b.H. Dec. 4, 1959 [Dec. 6, 1958; Dec. 9, 1958], No. 41238/59. Class 120 (2). In drafting-mechanism comprising a carrier arm 2 for twin top rolls 8 pivoted on a bar 1, the arm supports magnets 4 by which the top rolls are weighted. In Fig. 1 the magnets are supported by rails 5 formed on the arm and engaging grooves in the magnets which are fixed where desired by screws 7. Each magnet carries fixed or rotatably the central part 8<SP>1</SP> of the upper rolls, and is shaped to embrace the corresponding part 11 of the lower rolls with the interposition of a piece of plastic material. In Fig. 4, each magnet 14 is in a non-magnetic sleeve 15 in a soft-iron member 16. The magnet carries the central part 8<SP>1</SP> of the upper roll pair. In the member 16 is a non-magnetic core 18 with two soft-iron members 19 which can be rotated to vary or relieve the magnetic flux and the weighting effect. The cores 18 for each or all the arms may be operated together by linkwork. In Fig. 7 each magnet 30 is round and is adjustably carried on a saddle 27 having an inclined or other guide recess 28 and a retaining spring 29 for the central part of upper roll: the saddle is carried by a guide arm 24 on a pivot 23 connected to the arm or to a U-shaped stirrup 22 fixed where desired by a scrow 25 and having an adjustable stop 26 to limit the downward travel of the arm 2. The bottom rolls are so mounted that they cannot be lifted upwardly when the carrier arm is raised, and a stop 33 is provided, which may be such that the arm cannot rest on the bottom rolls after all the top rolls have been removed. Also, a member may be associated with the stop which can be operated mechanically, pneumatically or hydraulically to lift the arm 2 until the bottom rolls are outside the range of influence of the magnets, after which it is possible to further move the arm by hand. The arm is loosely mounted on the bar being positioned between stops by springs. The arm may take the form of a flat bar with a central slot for adjustably positioning the magnets (Fig. 9, not shown).
