Title: Prepn. of very hard polyethylene waxes oxidates - by oxidising low viscosity polyethylene hard waxes obtd. by reacting hydrogen-ethylene mixt. with a high pressure Ziegler catalyst
Inventor: ADLER PETER DR
IPC: C08F8/06
Filed: 1992-10-21
Abstract: Prepn. of very hard polyethylene wax oxidates comprises using oxygen at temps. greater than the m.pt. of the polymer and hard, highly-crystalline polyethylene waxes prepd. by the Ziegler process at temps. greater than or equal to 200 deg. C., having a melt viscosity of 50-500 mm2/5 at 140 deg. C., a needle penetration value of 0.1-0.5 x 10xpower-1, a non-uniformity value of 2-2.5 and degree of branching of less than or equal to 0.15 per 100 C atoms. The prepn. takes place in a stirred blow column reactor for oxidn. to occur. The polyethylene hard wax starting prods. are pref. prepd. by coordinative polymerisation of ethylene in the presence of hydrogen as chain regulator, using a Ziegler catalyst well-known for high pressure processes. The catalyst, comprising a MgCl2- and Al-contg. carrier and TiCl4 as transition metal cpd. is prepd. by (i) activating Mg powder in a liq. phase with iodine; (ii) reacting the activated Mg with n-butyl chloride at 100-130 deg. C. and a nBuCl-Mg mol. ratio of 1.3-1.5, with the first half of the nBuCl being added within 1 hr. and the second half within 2 hrs.; (iii) treating the obtd. prim. carrier with diethyl aluminium chloride at 25-45 deg. C. and an Al-Mg mol. ratio of 0.3-0.7; (iv) adding CCl4 to the obtd. alkyl aluminium soln. to vive a gross compsn. of AlR1.5Cl1.5 (R = alkyl), and then (v) fixing Ti onto the carrier at 25-45 deg. C. using TiCl3 prepd. in situ from TiCl4. The catalyst is used in a lower satd. aliphatic hydrocarbon solvent at 200-260 deg. C., 2-30 MPa in a homogeneous phase with a H2/C2H4 mol. ratio greater than or equal to 4:1. Oxidn. is pref. carried out at 140-170 (155-165) deg. C. using mol. oxygen, without inner or outer cooling. USE/ADVANTAGE - For forming high hardness films and coatings, as plastic processing aids (e.g. dye batches, lubricants), as textile finishing agents and as additives for coloured printing inks, matt paints, adhesives and hardening paraffins. The obtd. wax oxidates require no intermediate processing prior to spraying or converting into emulsions, very little polymer degradation takes place during the reaction and the oxidn does not lead to discolouring of the prods.

Title: FIFO with data expansion-compression in binary steps - uses shifted counter outputs to control address generators for read=write
Inventor: TANIGUCHI MASAHARU
IPC: G06F7/78
Filed: 1993-06-28
Abstract: The FIFO (30) contains a memory matrix (12), read and write clock counters (16,13), read and write address decoders (18,14), write register (15) clocked by a write clock (WK2), and a sense amplifier/buffer (19) clocked by a read clock (RK2). The FIFO implements data reduction in binary steps for example a reduction of 1/2 reads alternate data bits into the memory: '00011011' is input as '0011'. The scaling is implemented by connecting write counter outputs appropriately to the write address generator. For data expansion, data are repeated for 2,4,8 clock periods etc. The connection of the read counter (16) outputs (Q1,Q2,Q3) to the address decoder (18) (A0,A1,A2) implements an expansion factor of 2. ADVANTAGE - Data reduction/expansion by simple circuit addition to FIFO circuit.

Patent DE-4324035-A1 (DE)
Title: Gas turbine
Inventor: INKER MARK
IPC: F02C7/18
Filed: 1993-07-17
Abstract: A gas turbine has a turbine part and a combustion chamber. The hot gases pass from the combustion chamber via an annular turbine inlet (19), which is separated towards the outside from a plenum (18), which guides compressed air, by an outer shell (14), into the turbine part. The turbine part is surrounded like a jacket by a hollow cylindrical blade carrier (3) which is fitted with fixed blades (stationary blades) (1). A functional combination of the sealing and guidance of the outer shell of the turbine inlet is achieved at a point in this gas turbine owing to the fact that the outer shell (14) is joined to the blade carrier (3) at its end facing the turbine part via a movable seal (20) which guides and limits the thermally induced movement of the outer shell (14) in the axial and radial directions. <IMAGE>

Title: Microparticle reflow solder and mfg. process - where solid solder is melted in anaerobic fluid forming ribbon of microspheres, and after sepg. off, fluid spheres are encapsulated in organic polymer
Inventor: TEUSCHLER HANS-JOACHIM DR RER
IPC: B23K35/02
Filed: 1994-01-25
Abstract: A microparticle based reflow solder for use in prodn. of microelectronic circuits is produced as a paste and oxidn. of the metal is prevented by encapsulating the 3-10 micron dia. spheres with an organic polymer. In a mfg. process the solid metal is melted in an organic fluid at high temp. and in a flow dispersion process is converted into a ribbon of spheres 3-10 micron dia. After drawing off most of the fluid the metal particles remain covered by a small amt. A soln. contg. a melamine resin is added while stirring to coat the individual metal spheres to a thickness of 50-250 nm. Microencapsulated organic material is the sepd. from the encapsulated metal. Solder spheres are encapsulated in an acid hardening polymer, esp. melamine. The solder paste contains 73-93% wt. of protected solder spheres. After coating in polymer the solder spheres are washed in solvent, sepd. and converted into a paste. The paste can be used for both hot gas and laser soldering of contacts. USE/ADVANTAGE - The process produces a solder in paste form for soldering contacts on microelectronic circuits using a screen printing process. Prevents surface oxidn. of the metal particles.
