Patent EP-0305831-A2 (EP)
Inventor: UHLIG UWE
IPC: B23Q17/12
Filed: 1988-08-20
Abstract: 2.1 In machine tools with rotational tools, in particular in grinding machines, vibrations can occur at the tool spindle which are due in particular to the fan of the tool-spindle motor and adversely affect the machining quality (grinding finish) of the workpiece. An increase in the machining quality of workpieces machined on such machines is therefore to be achieved with the invention. 2.2 It is therefore proposed to eliminate the vibration effects of the fan (12) in a controlled manner at least during the finish machining of the workpiece (4), in the course of which a control signal (SL), as a function of the measured temperature (T) of the workpiece spindle motor (11) and/or of the measured vibrations (S), is transmitted to the fan for switching it on or off or for changing its rotational speed. It is also possible to influence the fan by a programmed switching command (machine program). 2.3 The use of the proposed solution is possible in machine tools with rotational tools. But the solution is particularly intended for grinding machines. <IMAGE>

Abstract: A data acquisition circuit having arithmetic units (22) installed in a data bus and adapted to carry out correction such as dead-time correction and decay correction, and also having an address modification storage (12) installed in an address bus and adapted to carry out the process of changing raw data into a sinogram. As the size of memory matrices for positron ECT grows larger in recent years, software dependent on a CPU has tended to require more time for data processing and prevent image formation from taking place in real-time. The aim of the present invention is to allow data reduction and correction to be carried out in real-time.

Abstract: The present invention concerns a solid modelling system comprising means for generating a spatial representation of an object defined by a structure 30, Fig. 4, having a plurality of linked nodes representing the object in terms of solid geometric primitives combined by a logical expression, which is adapted to recognise redundant primitives automati­cally. In order to achieve this, bitmap generation logic (BGL) is provided for traversing at least certain of the nodes in the structure for generating a bitmap representing the part of the logical expression defined in the traversed nodes and redundant primitive logic (RPL) for testing the bitmap for logical redundancies indicative of redundant geometric primitives. 
     In a specific example of a solid modelling system described, each bit in the bitmap is representative of a respective one of the constit­uents of the primitives, a constituent being the volume formed by the intersection of primitives or their complements, and, in order to test for the redundancy of a primitive u, the logic RPL tests for equivalence of the corresponding utrue and ufalse constituents in the bitmap. The logic BGL additionally generates a table 68 of pointers to the primi­tives encountered during the traversal and the logic RPL deletes from the table 68 a pointer to a primitive which is found to be redundant. Node generation logic NGL is provided for replacing the nodes traversed by the first logic by a single truth table node which comprises the modified bitmap produced by the logic RPL and pointers to nodes defining the remaining primitives. Logic may also be provided for processing a relevance map indicative geometric information in combination with the bitmap.

Abstract: This invention relates to an improved process for the catalytic hydrogenation of methylene bridged polyphenylamines using rhodium as the catalyst to produce the methylene bridged polycyclohexylamine counterparts. The improvement for hydrogenating crude methylene bridged polyphenylamines, containing polyphenylamine oligomers and trace amounts of impurities, such as the formamide of the methylene bridged polyphenylamines, comprises contacting the crude polyphenylamine feed with a hydrogenation catalyst, other than rhodium, and one which is not a catalyst poison to rhodium, under conditions sufficient to at least partially hydrogenate the polyphenylamine mixture and then effecting hydrogenation of the methylene bridged polyphenylamine to the polycyclohexylamine counterpart in the presence of a rhodium catalyst. The pretreatment of the crude methylene bridged polyphenylamine feed apparently destroys the formamide derivatives and possibly other trace impurities in the mixture and thereby prevents rapid deactivation of the rhodium catalyst during hydrogenation of the aromatic ring.

Abstract: A method for producing a light-transmissive phase change ink printed substrate is described which comprises providing a substrate, and then printing on at least one surface of the substrate a predetermined pattern of a light-transmissive phase change ink which initially transmits light in a non-rectilinear path. The pattern of solidified phase change ink is then reoriented to form an ink layer of substantially uniform thickness. This ink layer will, in turn, produce an image which then will transmit light in a substantially rectilinear path. 
     In one aspect of the invention, the substrate is light transmissive, and the reoriented printed substrate exhibits a high degree of lightness and chroma, and transmits light in a substantially rectilinear path. In this way, the reoriented printed substrate can be used in a projection device to project an image containing clear, saturated colors.

Abstract: An enzyme, called diacetyl reductase, can be used to produce acetoin from diacetyl and can be isolated from Lactobacillus kefir, L. plantarum, L. brevis, L. buchneri; from Leuconostoc cremoris, Candida boidinii, Hansenula polymorpha, Kluyveromyces lactis or Torulopsis candida. Particularly expedient in this connection is a diacetyl reductase which is able to reduce diacetyl selectively to (+)-acetoin and can be obtained from one of the abovementioned Lactobacillus strains. Two reductases (E1 and E2) which are capable of enantiomer formation and demonstrably have molecular weights of 66,000 +/- 5,000 and 74,000 +/- 5,000 have been highly purified, and it has been found that the pH optimum for the reduction reaction is 5 +/- 1; the temperature optimum is 70 DEG C; and the residual activity after storage at 6 DEG C and a pH between 5 and 10 for one week is 60%. There is furthermore substrate specificity for diacetyl, pyruvate and pyruvate ethyl ester besides other diketones such as acetylacetone, phenylpyruvate, diacetylbenzene and hexanedione.
