Title: 17-Acylated 9-fluoro-prednisolone derivs. - which are local antiinflammatories free of systemic effects and useful for treating e.g. eczema and asthma
Inventor: ANNEN KLAUS DR
IPC: C07J21/00
Filed: 1978-03-03
Abstract: Prednisolone derivs. are of formula (I). In (I) R1 is 1-8C alkanoyl or benzoyl. X is F, Cl or 3-8C alkanoyloxy. They are prepd. e.g. by reacting the corresp. 9.11-epoxide with HF. (I) have powerful local antiinflammatory properties (often superior to the best known corticoids) but only very weak systemic effects. They are useful for treating e.g. contact dermatitis, eczema, pruritis, psoriasis, etc. and can also be formulated for inhalation to treat allergic disorders such as bronchial asthma or rhinitis. (I) are prepd. from diosgenin relatively cheaply with overall yields of around 15%, c.f. 0.5-5% for known corticoids. In an example, 17alpha-acetoxy-9alpha-fluoro-11beta-hydroxy-21-propionyloxy-1,4-- pregnadiene-3,20-dione was made from 17alpha, 21-(1-ethoxyethylidenedioxy)-9alpha-F-11beta-hydroxy-1,4-pregnadi- ene-3,20-dione by reacting with acetic acid, then propionic anhydride.

Title: Magnetic trip for protective circuit breaker - has magnetic circuit shunt of high permeability, but with spot-like deformations reducing permeability
Inventor: KOTOLL SIGMAR
IPC: H01H71/32
Filed: 1978-07-11
Abstract: The breaker tripping system contains pole shoes, a permanent magnet, a tripping coil, a moving armature, and a magnetic shunt (4), which consists of a material with a high permeability after suitable annealing. The annealing process, however, provides mechanic deformation spots (8), at which the permeability is reduced. Preferably the mechanical deformation is formed by pinching in an extent related to the shunt strip width and thickness. In the pinched section the permeability is typically less than one tenth of the permeability in the remaining sections of the shunt material. The shunt and the pole shoes (5) may be formed in one piece, stamped of flat material and bent into a U.

Patent DE-2846316-A1 (DE)
Title: Automatic mask aligning system for semiconductor prodn. - uses opto-electronic scanner for grids on mask and silicon wafer, with results integrated and averaged as to intensity distributions
Inventor: DOEMENS GUENTER DR ING
IPC: G03F9/00
Filed: 1978-10-24
Abstract: Sets of orthogonal lines are formed on the mask and on the silicon wafer. Each of the two sets is then scanned opto-electronically to produce two intensity distributions. The intensity along each scan line is integrated. The results for adjacent scan lines are subtracted from one another and then processed digitally to produce pairs of peaks. The average of the peaks in each pair is taken. The location of this averge marks the centre of the gradual or blurred edge of a line in either of the two sets of lines. Thus the centre of the line, or the centre of the gap between lines can be located. Continuous averaging in this way reduces each set of lines to two crosses which, when aligned, ensure that the sets of lines are also aligned, and thus the mask and wafer as well. Alignment lines with unsharp edges on both mask and wafer can be scanned fully automatically, e.g. using a TV camera or a laser, with no loss of positioned precision due to the lack of contrast at the edge of the lines.

Title: Multiple socket has disabling circuit - which only supplies sockets with current when main socket draws load current
Inventor: NIKOLAI REINHARD
IPC: H01R13/66
Filed: 1979-03-12
Abstract: The multiple socket has a disabling circuit that prevents all its sockets being supplied with current unless its main socket is connected to a load -- i.e. is carrying a load current. Which means: when the equipment connected to the main socket is switched on, the supplies to all the other pieces of equipment connected to the other sockets are switched on at the same time. The disabling circuit consists essentially of a relay (Re)(or triac) connected in series between one incoming supply pole and one contact of the main socket (4). The relay's contacts (S) connect the supply through to all the parallel-coupled dependent sockets (5). (A cable with a plug attached is fitted to the multiple socket).

Title: Measurement method for thermal conductivity and capacity - calculates laplace integrals and transforms of temp. changes w.r.t. comparator
Inventor: IIDA YOSHIHIRO
IPC: G01N25/00
Filed: 1979-05-15
Abstract: A method of determining the thermal characteristics e.g. conductivity and capacity of a measurement specimen enables the use of fundamental and fully optional boundary and initial temp. conditions, thus expanding the permissible range of conditions for measurement compared with existing methods. It is realised using a simply constructed device of high accuracy and with practically no difficulties. The measurement specimen (1) is first brought into close contact with a comparison specimen (2). The temp. variation is measured at one comparison specimen point and one or two measurement specimen points. The laplace integrals of the temp. variations are calculated and the laplace transform of the thermal conductivity equation applied to the integrals to determine thermal characteristics such as conductivity, diffusivity, and capacity simultaneously.

Filed: 1979-05-28
Abstract: A moulding compsn. comprising 100 pts.wt. polyethylene prepd. with a Phillips type Cr contg. catalyst with a density >0.935 g/cm3, a melt index (DIN 53735, 190 degrees C, 2.16 kg) 16 g/10 min and a soln. viscosity (DIN 5378, page 4) of 0.8-5 cm3/g; 0.5-1 pt.wt. tris-(2,4-di-1-8C-alkyl-phenyl)-phosphile and 0.02-0.8 pt.wt. Zn stearate, also contains 0.05-1 pt.wt. 1, 3, 5-tri-methyl-2, 4, 6-tris-(3', 5'-di-tert-butyl-4'-hydroxy-benzyl)-benzene and opt. other additives. The compsn. has a well balanced ratio of melt index to melt elongation. This ratio is not adversely affected as in conventional compsns. by a reduction in melt index during processing (MI-drop) or by an undesiredly good melt elongation which leads to stress in injection moulded or blown goods due to the difference in average and thinnest wall thicknesses. The compsn. also has high UV resistance. The compsn. can be used to prepare 10-30 mu thick, biaxially stretched blown films with a blow ratio of 1:10 pref. 1:2-1:7 or injection moulded goods e.g. heating oil tanks.
