Inventor: GUSTAFSSON PER
IPC: E21B4/14
Filed: 1990-01-12
Abstract: In a water driven down-the-hole rock drill, the rearward end of an associated hammer is provided with a drive piston reciprocable in a cylinder located adjacent the rear of the drill. The front end of the hammer is guided for reciprocation in a bearing located adjacent an anvil of a drill bit. Between the cylinder and the bearing the hammer is elongated and enlarged diametrically relative to the piston. The enlarged hammer portion reciprocates freely in a chamber formed by an outer casing of the drill. Drive water is expelled from the cylinder and flushes the hole drilled by the bit. An open ended tubular valve reciprocates to control a duct connecting the interior of the valve to coaxial through-flushing channels in the hammer and the drill bit.

Abstract: PCT No. PCT/GB90/00323 Sec. 371 Date Oct. 5, 1990 Sec. 102(e) Date Oct. 5, 1990 PCT Filed Mar. 2, 1990 PCT Pub. No. WO90/09862 PCT Pub. Date Sep. 7, 1990.The machine is provided with a set of two pairs of die halves 60, 62 (FIG. 7) mounted in a framework on hydraulically actuated piston and cylinder assemblies. The die halves 60 and 62 of each pair are relatively radially reciprocable to grip or release a workpiece 102, 104 and the two pairs of die halves are relatively axially reciprocable to effect cold pressure welding together of end portions of the workpieces 102, 104. Adjoining end faces of the die halves are formed with nose portions 100 having inner anvil edges for effecting welding flash removal from the workpieces. In operation, the die halves are moved in sequence to grip the workpieces; to urge the ends of the workpieces together to form a cold pressure weld upset zone; to release the workpieces; to grip one of the workpieces; to urge the gripped workpiece axially relative to a pair of anvil edges to clear flash material from the upset to maintain the cross-sectional area at the weld upset zone substantially constant; and to re-position the upset weld zone centrally of the nose portions to repeat the sequence. Removal of the flash material intermediate consecutive weld upsets is effected in alternate directions. The anvil edges may be staggered, angled or of helical form to enhance the shearing effect to clear the flash material from the upset weld zone.

Title: Process for improving thermal stability of synthetic lubes
Inventor: HO SUZZY C H
IPC: C10N20/02
Filed: 1990-08-29
Granted: 1999-02-09
Abstract: A process is disclosed for improving the thermal stability of polyalpha-olefin lubricants by contacting the lubricant with an acidic catalyst for a time and at a temperature sufficient to achieve the skeletal isomerization of the molecular structure of the lubricant. The reaction is carried out preferably on unhydrogenated synthetic lubricants in contact with Lewis acid catalysts. Following the isomerization reaction, the unsaturated lubricant is hydrogenated to produce lubricant with better thermal stability. Surprisingly, when the isomerization reaction is carried out using unsaturated oligomer produced from the oligomerization of alpha-olefins in contact with reduced Group VIB metal oxide catalyst on porous support as starting material the viscometric properties of the lubricant, e.g., viscosity and VI, are not significantly altered, although the thermal stability of the lubricant is substantially increased. The reaction of the present invention may be carried out neat or in the presence of a solvent. Improvements in thermal stability are observed over a wide range of catalyst concentrations. Concentrations of about 10 weight percent are preferred with aluminum chloride catalyst.

Title: Switchless automatic call distribution system
Inventor: GECHTER JERRY
IPC: H04M3/00
Filed: 1990-09-07
Granted: 1994-10-18
Abstract: Disclosed is an automatic call distributing system for automatically distributing telephone calls placed over a network to agent stations connected to the network by network service interfaces.  The system includes a receiving means that is connected to the network by a network service interface and receives agent status messages and a call arrival message from the network indicating that an incoming call has been made on the network.  It also includes a routing means that is responsive to the receiving means to generate a routing signal that is provided to the network to connect the incoming call to an agent station through the network.  In this manner, the automatic call distributing system has great flexibility in locating agents, so long as they are connected to the network, and in deciding which agent an incoming  call should be routed to.  At the same time, the system employs the switching hardware of the network to actually perform the switching function, thereby avoiding costs and maintenance associated with the switching hardware.  In addition, the system permits the sytem operator to maintain control of routing and any data associated with routing by the system operator.  This leads to flexibility in monitoring and reporting agent activity for management purposes.
