Granted: 1993-02-03
Abstract: PCT No. PCT/GB90/01006 Sec. 371 Date Dec. 30, 1991 Sec. 102(e) Date Dec. 30, 1991 PCT Filed Jun. 29, 1990 PCT Pub. No. WO91/00411 PCT Pub. Date Jan. 10, 1991.A drill string component for preventing chafing of a drill casing as a result of contact between the drill casing and a rotating drill string comprises a central mandrel (2) having rotatably mounted thereon a sleeve (11). The sleeve (11) is retained between shoulders defined on the mandrel to prevent accidental loss of the sleeve in the event of excessive wear in the supporting bearings. Axial thrust loads are transferred from the outer sleeve (11) to the mandrel by way of thrust bearings supported on the mandrel shoulders. Seals (24A, 24B) located between the outer sleeve seal bodies (23) and an inner sleeve (9) prevent the ingress of contaminants to the zone of bushings (12, 13) which rotatably support the outer sleeve.

Title: Clad bonding wire for semiconductor device
Inventor: TOYOFUKU KATSUYUKI
IPC: H01L23/49
Filed: 1991-07-18
Granted: 1994-09-28
Abstract: A clad bonding wire for electrically connecting the bonding pad of a semiconductor device to an external lead comprises a core wire formed on one of high-purity Pd or a Pd alloy, high-purity Au or a Au alloy, high-purity Pt or a Pt alloy, and high-purity Ag or a Ag alloy, and a cladding cladding the core wire and formed of another one of the foregoing materials other than that forming the core wire. The wire-to-cladding diameter ratio D2/D1 is in the range of 15% to 60% or 85% to 99. When the tip of the clad bonding wire is heated to form a ball, part of the core wire and part of the cladding in a neck formed behind the ball diffuse into each other to form an alloy of the materials forming the core wire and the cladding between the core wire and the cladding to enhance the mechanical strength of the neck beyond that of other portion of the clad bonding wire.

Title: Method and apparatus for power generation
Inventor: KAKOVITCH THOMAS
IPC: F01K21/04
Filed: 1992-11-27
Granted: 1995-08-09
Abstract: A method and apparatus for converting heat energy to mechanical energy with greater efficiency. According to the method, heat energy is applied to a working fluid in a reservoir sufficient to convert the working fluid to a vapor and the working fluid is passed in vapor form to means such as a generator for converting the energy therein to mechanical work. The working fluid is then recycled to the reservoir. In order to increase the efficiency of this process, a gas having a molecular weight no greater than the approximate molecular weight of the working fluid is added to the working fluid in the reservoir, separated from the working fluid downstream from the reservoir, compressed and returned to the reservoir.

Granted: 1986-08-13
Abstract: A stabiliser for a long tubular element rotating a drill bit ina bore-hole consists of a hollow cylindrical body in hard material comprising a wall and a central opening which extends over the whole of its length, which corresps. to the outer transverse dimensions of the long tubular element, and which is capable of receiving a length of the latter, the wall having a thickness such that it can flex. The stabiliser has blades made of a rigid material placed over the outer part of the hollow cylindrical body and extending over its whole length to bear on the inner surface of a bore-hole to stabilise the long tubular element in the bore-hole while it is rotating the drill bit. An open slot extends over the whole length of the hollow cylindrical body. There are means of tightening the flexible hollow cylindrical body on the outer surface of the long tubular element, allowing the stabiliser to resist the couple and the linear forces exerted on it resulting from the engagement of the blades with the internal surface of the bore hole. The stabiliser is pref. made of non-magnetic material. The stabiliser can be positioned at any desired place on a rod It can be tightened on the outer surface of a rod without wear or deterioration during use. It ensures adequate stabilisation without increasing the number of screwed assemblages in the train of drilling rods. It can be positioned rapidly at the surface. It is made of non-magnatic material which does not prejudice magnetic inspection of the bottom of the bore-hole.
