Title: Steering device
Inventor: BASE JAMES D
IPC: E21B7/06
Filed: 1991-10-24
Abstract: A directional drilling device includes an expandible stabilizer and a variable angle bent sub, both of which are operated by axial movement of a common mandrel such that, for straight hole drilling, the bent sub has zero angle whilst the stabilizer pads are expanded, and for directional drilling, the mandrel is moved axially to retract the stabilizer pads and create a bend in the bent sub, the mandrel then being releasably locked in its new position.
Patent GB-912934-A (GB)
Abstract: 912,934. Mixing liquids. PRATOLONGO, M. Jan. 28, 1959 [Nov. 13, 1958], No. 36578/58. Class 86. [Also in Group XXVIII] A petrol pump delivery nozzle has a mixing chamber into which can be delivered a metered quantity of oil through a detachable coupling incorporating a valve; the oil is washed out of the mixing chamber by, and mixed with, the petrol on operation of the petrol delivery trigger valve. The nozzle also has a closing valve. Oil is supplied to a transparent plastic mixing chamber 71 from an oil metering pump through a delivery pipe having a valved coupling (see Group XXVIII). The coupling has a sleeve which embraces the annulus 6 and is retained by steel balls 5, and a cylindrical extension 90, see Fig. 3 of the Complete Specification (not shown) which depresses the cylindrical inlet valve 34 admitting oil by holes 81. The pin 36 on valve 34 depresses in turn flange 85 opening air release valve 37. When the required amount of oil has been metered into chamber 71 the coupling is detached. Operation of the trigger 54 then opens the valve 47 admitting petrol through conduits 75, 80. Fluid pressure opens the anti-drip valve 61 and petrol passes into the tube 77 having holes 30 which ensure thorough penetration of the oil by petrol. The mixture is then delivered through the nozzle 70 which has a valve 68 operated manually but opened by the pressura of the discharging fluid. In an alternative arrangement, see Fig. 1 of the Provisional Specification (not shown) the anti-drip valve 61 discharges towards the blades of a turbine stirrer which replaces the tube 77. Specification 912,933 is referred to.

Title: Detection of Herpesvirus simiae
Inventor: TITBALL RICHARD WILLIAM
IPC: C12Q1/70
Filed: 1992-01-31
Abstract: The close relationship between Herpesvirus simiae (B virus), SA-8, HSV-1 and HSV-2 makes them difficult to differentiate by immunological methods; the lethal effects of the former virus in man making the development of a differential test desirable. There is provided a method for identifying B virus DNA by amplifying a characteristic double stranded oligonucleotide sequence from it using PCT techniques and oligonucleotides which can be used to prime polymerase chain reactions to amplify said polynucleotide sequence specific to said B virus. Oligonucleotides which can be labelled and used as probes capable of hybridizing specifically with the amplification products produced by positive PCRs are described enabling the differentiation of Herpesvirus simiae (B) virus from the most likely causes of false positives.

Title: Separation of solids from liquids
Inventor: BACHE JOHN CEDRIC
IPC: B03B5/54
Filed: 1992-11-12
Abstract: Grit is separated from sewage in two stages (Fig. 1), the first comprising a settling tank from whose sump a liquid mixture of settled grit and organic contaminants is pumped to the inlet end of a second stage, which comprises an elongate inclined trough in which the grit settles while the organics are carried along with the liquid flow. The trough 17 may be adjustably inclined, with flow uphill or downhill or horizontal. In Fig. 6 the liquid flows out of the trough to the left of baffle 28, but after some grit has accumulated the flow is stopped and the trough is tilted, pulling its outlet end to the right of baffle 28. The grit is then flushed or scraped out. In Figs. 7, 8 the trough is fixed and grit removed by blades on an endless conveyor or by a screw device lowered into the trough when required. in Fig. 9 grit is flushed from a tilted trough into a hopper with an inclined screw conveyor. The trough may be vibrated in use. <IMAGE>

Title: Magnetic material with magnetorestrictive properties
Inventor: GIBBS MICHAEL RICHARD JOHN
IPC: H01L41/20
Filed: 1992-12-09
Abstract: A magnetic material of at least two component parts arranged to have respective structures which mutually are not homogenous, the structure of one part cooperating with the structure of the other to assist the magnetostrictive behaviour of the material. The cooperation can be the structure of one part altering the atomic spacing of the other part [Fig. 1 Fig. 2] and the alteration can be an increase from the usual atomic spacing. A layer may have a lattice structure modified by an overlaid layer. The modification may be that the lattice of the second layer adopts at least approximately the lattice of the first layer. There can be contiguous component parts and the cooperation can be a pseudo free surface on at least one said part or a reduced restriction of the local moment otherwise achieved by the contiguous component parts [Fig. 5]. Reduction in the thickness of the layers has the effect of making the magnetorestriction more positive whilst annealing of the composite structure will also cause an increase of the magnetorestriction indicating that the metals of the layers, eg Fe and Co, have alloyed. A component can be at least partly an alloy and the alloy can have ratio other than the usual one for said alloy. One of the components can be non-magnetic eg Al, Mg, Ag, Au or SiO* subscript minus * or both can be magnetic eg Fe, Ni, Co, Gd, Tb.

Title: Framed panels
Inventor: NEWNHAM CHRISTOPHER
IPC: E04H17/20
Filed: 1993-06-14
Abstract: A framed panel has tubular preferably box-section, frame members (3,) surrounding an infill member (1,) which may be a metal mesh or grid, or a metal sheet. Along the inner face of each member there is a gap (4,) through which extends an edge portion of the infill member. Within the tubular members (3,) these edge portions are made captive. With a mesh or grid (1) a toothed strip (5) may interdigitate with the strands to prevent escape through the gap (4). Otherwise, the gap may be at the base of a valley in the associated inner face and the tubular -members (7) may have a resilience allowing thickened edge portions of the infill member (1,) to snap through and then become captive. Such framed panels can be interconnected and supported by intermediate plates or strips with lugs which engage apertures in the outer faces of the tubular frame members so as to make a fence. <IMAGE>

Abstract: In a method of determining motion vectors for a picture signal, in which each picture is divided into blocks and a motion vector is determined for each block in at least two steps, a number of motion vectors being assumed to be possible in each step and a deviation function for each pixel of the block being used for each of these assumed motion vectors, the most favorable vector being selected in dependence upon the value of its deviation function and being selected as one of the assumed vectors for the next step, if any, an optimal insensitivity to noise is obtained in that in the first step a first predetermined value is subtracted from the determined value of the deviation function of the vector having the smallest length, the thus reduced value being subsequently compared with the determined values of the deviation function of the other assumed motion vectors, and in that in a subsequent step a further predetermined value is subtracted from the value of the deviation function of that assumed motion vector which was determined as the most favorable motion vector in the previous step, and in that the thus reduced value of the deviation function of this vector is compared with the values of the deviation function of the other vectors of the same step for determining the most favorable vector. Each further predetermined valve is allow than the lasts. <IMAGE>
