Title: Internal combustion engine spark ignition system components
Inventor: HALILOVIC ESREF
IPC: F02P9/00
Filed: 1983-07-11
Abstract: An internal combustion engine spark ignition system component, for self-exciting ionisation commutation of the high-voltage impulse energy, comprises a gas-filled housing (1) of electrically insulating material sealed by two electrodes (3,4) and having an apertured photo-emissive disc (2) in the gap between the electrodes, the disc being at most a third of the gap in thickness, being nearer one electrode (the anode in use) than the other, and having a central aperture equal in diameter to axially aligned projections (e.g. 3a) extending from each electrode (3, 4). An outer metal housing (5) may be provided as a screen. It amplifies the spark, lengthens the working life of the sparking-plug, provides for correct working of the engine under severe conditions and improves engine economy. The ignition circuit, Fig. 2 (not shown) is discussed in detail. An outer metal housing 5 may be provided as a screen. <IMAGE>

Title: Combination weighing machines and method
Inventor: STEEL HENRY JOHN
IPC: G01G19/393
Filed: 1983-12-15
Abstract: The machine comprises one or more weighers 6, 20 for producing electrical output signals dependent on the weights of samples weighed thereby, and two or more storage holders A1 and A2 associated with each weigher 6, 20 for holding samples discharged from the associated weigher holder 6, which may also be used as a storage holder. Circuitry 25 makes a selection from amongst the samples in all the storage holders A1, A2 in dependence on the weights of the samples stored in memories 22, 23 and the selected samples are discharged to form a target batch weight. Feedback control means may be provided which adjust the target weights of samples used subsequently to refill empty storage holders in the light of the weights of the remaining samples, so that convergence to the target batch weight and selection of the remaining samples are both promoted during successive cycles. <IMAGE>
Patent GB-2133939-A (GB)
Title: An h v d c cable protection system
Inventor: BODEN MICHAEL JAMES
IPC: H02J3/36
Filed: 1984-01-11
Abstract: An H.V.D.C. cable protection system in which a transmission cablehas a normal polarity with respect to earth determined by a normal power flow direction. In the event of a fault, a reflected voltage surge on the line can in some cases give a 100% reverse polarity voltage on the line, with the result that the cable can be damaged unless it is designed (at significant extra cost) to withstand such voltage reversal. According to the invention a diode rectifier is connected between the lines at each end of the cable in such direction as to be reverse biased in normal operation. A reverse voltage on the line is thus limited to the forward drop of the diode. Since this would produce a very large diode fault current a resistance is incorporated in series with the diode to limit the current even though at a sacrifice of a small reverse voltage.

Title: Method and apparatus for conveying particulate material
Inventor: SULLIVAN THOMAS J
IPC: B65G33/32
Filed: 1984-01-17
Abstract: To convey particulate materials such as grain to a top central cavity of a large container such as an on-farm silo (2) or bin, there are provided a first auger-containing flexibly roof mounted conveyor section (10) having on its receiving end (14A) contractible jaw members (208, 209) to releasably engage a second cooperating ground-adjacent auger-containing conveyor section (16). Keys and dogs on the augers cause the auger end (114) in the second section (16) to drive the auger shaft (106) in the first section (10). A carriage (22) supports the ground-adjacent conveyor section (16). By making the roof-mounted section (10) of suitable length to accommodate the geometry of the silo (2) or bin, any of a great variety of bin geometries may be accommodated with the use of a single standard length of ground-adjacent conveyor section (16). <IMAGE>

Title: Heterogeneous binding assay
Inventor: BAKER TERENCE SEWARD
IPC: G01N33/543
Filed: 1984-03-14
Abstract: A heterogeneous binding assay in which a liquid component and a granular particulate solid phase are incubated together for a predetermined period of time characterised in that the density of the liquid component is controlled such that it is substantially equal to the density of the granular particulate solid phase, thus preventing sedimentation. After incubation, the density of the liquid component may be reduced allowing unit gravity sedimentation and hence separation of the solid phase from the liquid component.

Filed: 1987-02-04
Abstract: Fluid-flow control apparatus and method by which magnetically-positionable elements (23) within a rigid body (9) can be externally manipulated using controlling source of magnetic flux (39).

Title: Open jaw ratchet spanner assembly
Inventor: MANWARING ALAN
IPC: B25B13/10
Filed: 1987-10-09
Abstract: An open jaw insert (42, 71) fits inside an open holder (40, 70). Two spring loaded paws (43, 44), on the element (42) Fig. 4 interengage teeth (46) around the inside of the holder (40) in the form of a one-way ratchet. The distance between the pawls (43, 44) is greater than the open holder gap so that the assembly still functions when one of the pawls is aligned with the holder opening. Alternatively, a single pawl (72) Fig. 7 has a sufficiently large engagement surface to span the opening, in this case, of the insert, since the paw is in the holder. The holder or insert may have an adjustable gap. <IMAGE>
