Classes 1(1) and 32 Oligomers of 1,3-dienes such as butadiene and isoprene are obtained from the monomer in the presence of a clear catalyst solution obtained from (1) a titanium compound, (2) a reducing metal of Group IA, IIA, IIB, IIIA, III B , IV B  and/or VII B  and optionally (3) a halide of an element of Group IIa, IIIA, IVA and/or V A , aluminium and/or an aluminium halide being essential in an aromatic hydrocarbon or halohydrocarbon; there may also be added (4) a complexing agent for the halide. The titanium compound (1) may be an alkoxylate, a halide, a mixed alkoxylate-halide or an organotitanium halide. The metal (2) may be Li, Ne, K, Be, Mg, Ca, Sr, Ba, B, Al, Ga, In, Tl, Zn, Cd, Ti, Zr, Ce or Mn or alloys thereof in powder or granula form. Specified halides (3) are B Cl 3 , Al Cl 3 , Al Br 3 , Al I 3 , Ga Br 3 , In Cl 3 , Tl Cl 3 , C Cl 4 , Si Cl 4 , Sn Cl 4 , Zn Cl 2  Zn I a , Cd Cl 2 , P Cl 3  and Sb Cl 3 . The mol. ratios of (1):(2) may be 2:1 to 1:300 and of (2):(3), 1:5 to 3:1 and the amount of catalyst may be as small as 0À2% by weight of the diene. The aromatic hydrocarbon or halohydrocarbon solvent may boil in the range 80‹-300‹C., several being specified, and used in a weight ratio to catalyst of 0À5-30:1. The components are mixed at 50‹-200‹C. and filtered, decanted or centrifuged if necessary. The complexing agent (4) may be an alkali or alkaline earth metal halide, hydride, cyanide or C 1 -C 4  carboxylate, or an organic ether, thioether, sulphoxide, amine, amine oxide, phosphine or phosphine oxide containing hydrocarbon groups, which may contain halogen, carbonyl, carboxy, cyano or carbalkoxy group, and the functional group of which may be in a heterocyclic ring. The molar ratio of complexing agent (4) to the total of titanium compound (1) and halide (3) may be 1:10 to 5:1. An aliphatic hydrocarbon diluent may also be added such that the total amount of diluent and aromatic solvent used is 0À05 to 5 times that of the diene.

Title: Method of coating a copper film on a ceramic substrate
Inventor: YOSHIZAWA IZURU
IPC: C23C18/18
Filed: 1995-01-30
Abstract: A method of forming a copper film on a ceramic substrate comprises the steps of forming an undercoat containing copper on the ceramic substrate, heat-treating the undercoated substrate in an oxidation atmosphere to obtain a copper oxide layer in a surface of the undercoat, reducing the copper oxide layer to a metallic copper layer within a bath of a reducing solution, and forming an additional copper layer on the metallic copper layer to obtain the copper film. As the reducing solution, a solution of a boron hydride salt, dimethylamine borane, or the like, can be utilized. In particular, when the reducing solution is of dimethylamine borane, the reducing step can be performed at a temperature between 30  DEG C and 50  DEG C. A second undercoat of bismuth may be formed on the copper undercoat, and the method may be used in forming copper circuit patterns on the ceramic substrate.

Title: Personal computer system for two or more users
Inventor: PERAELAE PAAVO
IPC: G06F3/0354
Filed: 1996-05-29
Abstract: A system including a personal computer (1) and a display (2) is usable by at least two persons (owner 3 and customer 5) in connection with an application which does not support multiple mice or multiple cursor presentations. Each person has a respective mouse (4,6) and means are provided whereby the customer can participate in the operation of the application, at least to the extent of being able to point to objects on the screen by means of a cursor, rather than having to point with a finger etc or communicate verbally. This is achieved, without needing to modify the application, by loading appropriate mouse driver software into the personal computer in order to generate an auxiliary cursor for the customer, or using appropriate mice hardware/firmware/software(Figs 3-5), so that the customer's mouse can control the owner's cursor when required.

Title: Apparatus for capturing and detaining ram-raid vehicles.
Inventor: SIMPSON WILFRED ALAN
IPC: E01F13/12
Filed: 1996-09-28
Abstract: An anti-ram-raid structure comprises a base plate 12 secured to the ground by bolts or other suitable robust attachments. An elongate tubular member 14 is rigidly attached to the base plate and inclined rearwardly. A pivotable cover tube 28 is releasably secured in line with the first tube 14 and pivoted at its other end to a vertical pillar 22 and a strut 24 both secured at their lower ends to the base plate 12. In use the structure is located with the inclined ramp member 14 facing the direction of the ram-raid threat. The vertical height of the first tube 14 is selected with regard to the typical geometry of a vehicle such that a vehicle driven towards a structure will initially engage the inclined surface defined by the first tube 14, which starts to remove the load from the vehicle wheels. Once the leading part of the vehicle structure has passed the end of the tube 14, the pivotable cover tube 28 will pivot downwardly exposing a gap 26 having an overhanging portion, thereby tending to entrap part of the vehicle structure. The pivotable cover tube 28 may be alarmed, and the structure may be modified to include hinges so that the structure may be folded down sideways to allow access to authorised vehicles.

Title: A packer for a wellbore
Inventor: YOKLEY JOHN MARK
IPC: E21B33/14
Filed: 1997-02-28
Abstract: A liner packer assembly includes a liner packer (40) having a tubular body with an aperture (80) for the flow of wellbore fluids. A packing element (90) is movably disposed on the tubular body between an open position on one side of the aperture (80) for allowing wellbore fluids to flow through the aperture (80) to a closed position on the other side of the aperture for closing flow through the aperture and for packing off the annulus between the packer (40) and an outer casing (14). During the cementing operation, drilling fluids and cement are allowed to flow through the annular area formed by the packer (40) and outer casing (14) and also through the aperture (80) in the tubular body of the packer (40) and up the inner annular area formed by the packer (40) and inner tubular string (as shown by the arrow). The inner and outer annular areas around the packer (40) together approximate the flow area below the packer (40) between the inner tubular string and the outer casing (14) in order to prevent a restriction of fluid flow around the packer.
