Filed: 1988-07-16
Abstract: In a position measuring device (1) in accordance with Figure 1, an inner housing (2) and an outer housing (9) are provided. The coefficients of thermal conductivity of the materials of the two housings (2, 9) are very different. With decreasing ambient temperature, the outer housing (9) cools more quickly on the basis of its better thermal conductivity than the inner housing (2), which is not such a good conductor, with the result that the moisture is precipitated in a non-deleterious way on the inner surfaces of the outer housing (9). <IMAGE>
Patent DE-3828382-A1 (DE)
Inventor: GRIMM WOLFGANG DR
IPC: G02B5/20
Filed: 1988-08-20
Abstract: A filter, for protection against the sun, of improved contrast sensitivity has a spectral transmission (T lambda ) which for wavelengths ( lambda ) of the incident radiation in the range  lambda < 350 nm </=1% and in the range 350< lambda <400 nm is less than 20%, and which in the range 400< lambda <500 nm reaches a value of 5-30% and thereafter, proceeding from the value for T500, increases linearly with the wavelength to its maximum value. This progression is achieved by coating or colouring the filter material. In this case, it is advantageous to provide a component of the coating or colouring so that the spectral transmission (T lambda ) outside the visible spectral range, i.e. for values  lambda >780 nm, quickly reaches a value <1% again. <IMAGE>

Inventor: PURCHIO ANTHONY F
IPC: C12P21/00
Filed: 1988-10-05
Abstract: cDNA clones coding for TGF- beta 2 which are used to construct expression vectors capable of directing the high-level expression of mature, biologically active TGF- beta 2 in transfected Chinese Hamster Ovary cells (CHO cells) are described. The TGF- beta 2 produced and secreted by CHO transfectants has a specific activity estimated to be about half that of recombinant TGF- beta 1. The clones were isolated from a tamoxifen-treated human prostatic adenocarcinoma cell line (PC-3) using oligonucleotide probes based on the partial amino acid sequence of purified TGF- beta 2 from an African green monkey cell line, BSC-40. The cDNA sequences predict that TGF- beta 2 is synthesized as polypeptide precursor forms from which the mature 112 amino acid TGF- beta 2 subunit is derived by proteolytic cleavage. The proteins coded for by the human TGF- beta 1 and TGF- beta 2 cDNAs show an overall homology of 41%. The mature and amino- terminal precursor regions show 71% and 31% homology respectively. Northern blot analysis identified TGF- beta 2 transcripts of 4.1 kb, 5.1 kb, and 6.5 kb using mRNA from several different sources. Analysis of polyadenylated RNA from tamoxifen-treated PC-3 cells showed that these cells contain higher amounts of TGF- beta 1 transcripts than TGF- beta 2, although they produce more TGF- beta 2 protein than TDF- beta 1. This suggests that there is a post-transcriptional level of regulation for the production of these proteins.
