Patent EP-0036931-A1 (EP)
Inventor: COOK PAUL ALBERT
IPC: H02P8/32
Filed: 1981-02-05
Abstract: The stepper motor damping control system and method is realized by switching the power supply connection(s) of energized motor phase windings alternatively ON and OFF at a predetermined relatively high fixed rate. Said switching is performed by the predrive control processing circuit (14) using a clock signal information (CLK) for switching one way and an information denoting equality between a voltage substantially proportional to the current flowing through said motor phase windings (SENSE SIGNALS) with a predetermined sawtooth sloped reference signal (Vref) synchronized with said clock signal for switching the other way.

Abstract: Strip-shaped terminal elements (1) for the connection without stripping of electrical conductors. Such a terminal element (1) should be designed such that it can be produced cost-effectively. For this purpose, within the strip (2) there is a cut-out (3), the centre region (4) of which is of circular design, zones (5, 6) extending in a wedge-shape being connected on both sides of this region (4) in the longitudinal direction of the strip (2). In this arrangement, the terminal element (1) is bent such that the circular-shaped region (4) is located at the apex of the bend. By these means, the conductor to be connected can be inserted easily and quickly and is made contact with securely in the zones (5, 6) extending in a wedge-shape in each case on opposite sides (Fig. 1). <IMAGE>

Abstract: This invention comprises a process for the microbial transformation, e.g., oxidation, esterification or hydrolysis, of a substantially water-immiscible organic substrate wherein a microorganism species capable of effecting the required transformation of said substrate is located on a porous, water-bearing, particulate inert support, suitably an inorganic oxide, the pore size being greater than the mean diameter of the micro-organism, thereby forming an immobilised system in which the micro-organism has an aqueous environment, and the immobilised system is contacted with the substrate and a source of the appropriate reactant, such as oxygen, acid and alcohol or water. 
     The invention includes also an immobilised cell system suitable for use in the foregoing process comprising a micro-organism capable of transforming a substantially water immiscible substrate supported on a porous, water-bearing particulate inert support having a pore size greater than the mean diameter of the micro- organism.

Abstract: Ethylene is oligomerized by reacting ethylene in methanol under oligomerization conditions in contact with a nickel ylide defined by the following Formula I:
     wherein R,, R2, R 3 , R 4 , R s , R6, R 7  and R a  are either alike or different members selected from the group consisting of hydrogen, alkyl radicals having from about one to about 24 carbon atoms, preferably from about one to about 10 carbon atoms; aryl radicals having from about six to about 20 carbon atoms, preferably from about six to about 10 carbon atoms; alkenyl radicals having from about two to about 30 carbons atoms, preferably from about two to about 20 carbon atoms; cycloalkyl radicals having from about three to about 40 carbon atoms, preferably from about three to about 30 carbon atoms; aralkyl and alkaryl radicals having from about six to about 40 carbon atoms, preferably from about six to about 30 carbon atoms; a halogen radical selected from the group consisting of fluorine, chlorine, bromine and iodine, preferably chlorine; a hydroxyl group; an alkoxy or aryloxy group; and a hydrocarbyl group, such as defined above, carrying halogen, hydroxyl or alkoxy or aryloxy; provided that at least one, preferably from about one to about four, of each of R, to R s  is a sulfonato group (-SO 3 - ) or an alkyl, aryl, alkenyl, cycloalkyl, aralkyl or alkaryl group carrying a sulfonato group; M is sulfur or oxygen, preferably oxygen; E is phosphorus, arsenic, antimony or nitrogen, preferably phosphorus; and F is phosphorus; arsernic or antimony, preferably phosphorus. There is thus obtained a reaction product containing (A) a methanol phase having dissolved therein the nickel ylide catalyst and (B) an alpha olefin phase. These two phases are then separated from each other to recover the alpha olefin phase. The use of methanol as the solvent medium causes the reaction product to resolve itself into two phases, an upper phase containing most of the oligomer product and a lower methanol phase carrying the catalyst dissolved therein. This permits easy separation of the product from the reaction mixture and also permits effective recycle of methanol with dissolved catalyst. The product obtained contains normal alpha olefins having from about four to about 100 carbon atoms, generally from about four to about 50 carbon atoms.

Abstract: In accordance with an illustrative embodiment of the present invention, a new and improved weight-on-bit and/or torque measuring apparatus for use in making measurements-while-drilling includes a tubular housing adapted to be attached in the drill string above the bit, the housing having diametrically opposed, radially directed holes that are enclosed to provide a sealed chamber isolated from ambient well fluids. The holes have peripheral wall surfaces to which are attached sensors that measure strain induced by axial and/or torsional loading of the housing. The strain sensors are attached to the walls at locations to be substantially insensitive to strains induced by temperature gradients, and an internal sleeve is utilized in combination with pressure equalization to eliminate spurious stresses in the region of the holes caused by pressure differences inside and outside the housing.

Filed: 1982-10-04
Abstract: A method and device are described for generating signal pulses for controlling a stepping motor. A pulse generator generates pulses at a predetermined frequency. The pulses are counted by a pulse counter. Each time a number of pulses, corresponding to a number forming part of a set of predetermined numbers, has been counted a signal is generated. These signals form the signal pulses. The number of pulses that have to be counted to form a signal pulse changes gradually in time whereby a controlled change of speed of the stepping motor is achieved.
