IPC: C07C49/613
Filed: 1965-12-15
Abstract: The invention comprises 4,5-seco-19-nor-androsta-3,5,17-trione and a process for the preparation of 19-nor-androst-4-ene-3,17-dione in which 4,5-seco-19-nor-androsta-3,5,17-trione is reacted with a cyclization agent, e.g. sodium methylate, sodium or potassium amylate or hydrochloric acid in the presence of acetic acid or a secondary amine.  The 4,5-seco-19-nor-androsta-3,5,17-trione starting material may be obtained either by oxidizing 17b -hydroxy-4,5-seco - 19 - nor - androst - 9 - ene - 3,5 - dione to 4,5 - seco - 19 - nor - androst - 9 - ene - 3,5,17 - trione which is then catalytically hydrogenated to 4,5 - seco - 19 - nor - androsta - 3,5,17 - trione, or by catalytically hydrogenating 17b -hydroxy-4,5-seco-19-nor-androst-9-ene-3,5-dione to 17b -hydroxy - 4,5 - seco - 19 - nor - androsta - 3,5 - dione, which is then oxidized to 4,5-seco-19-nor-androsta-3,5,17-trione.

Abstract: 1402130 Bidet attachments for sanitary closets P L COUTELLIER 17 Nov 1972 [18 Nov 1971] 53244/72 Heading E1C [Also in Division A4] A spray attachment for a sanitary closet or bidet consists of a spray head 2 which is fitted to a seat-lid or cover 1 for directing a spray of water into the bowl 9, which as shown is a bidet but may alternatively be a closet bowl (12, Fig. 2, not shown). The spray head 2 is mounted via a ball head 3 on a slideway 7 on the lid, the lower end of the slideway 7 having a release portion so that the head 2 may be removed for hand-held use. Water is fed to the spray head via a flexible hose 5 from a mixer tap 6. In the alternative construction for a sanitary closet (Fig. 2, not shown), the slideway is omitted and a valve in the rear wall of the closet bowl supplies water to the spray head. A low-flush cistern of the closet has a lid (10) provided with an up-turned rim which serves as a hand hold permitting invalids and elderly persons to sit facing the cistern.

Abstract: 1517119 Cathode-ray tube circuits INTERNATIONAL BUSINESS MACHINES CORP 22 Dec 1976 53583/76 Heading H4T To correct the deflection of a C.R.T., particularly a colour tube for alphanumeric-graphical display with three guns in delta, the scan is divided into areas, and for each a correction signal is stored digitally; when the scan is in a given area the respective correction is read, converted to analogue and applied to the tube. Three convergence coils 8, 9, 10 on the gun side of the scanning coils can respectively move the red and green beams at the bottom of the delta and the blue at the top in line with the centre of the delta, and a fourth coil 11 can move the blue beam laterally (Fig. 1a not shown). The scan is divided into eight horizontal zones and eight vertical zones (Fig. 3 not shown), and for a 384 line scan each horizontal zone is again divided into four sections of 12 lines and each vertical zone into four sections of <SP>1</SP>/ 32  of the line scan. For each of the 32 horizontal sections a basic coarse correction current I n  is applied to all three central coils 8, 9, 10 via D/A converter 17 and amplifiers 23-25, and similarly I v  for each of the 32 vertical sections using D/A converter 18: the information for both is held permanently in store 12 as two sets of 32 8-bit bytes (Fig. 5 not shown). For each of 64 areas formed by intersection of the 8 horizontal and 8 vertical zones, separate corrections for the four coils are stored as 64 24-bit words each comprising four 6-bit bytes corresponding to the four coils (Fig. 6 not shown). The error correction store 13 can be loaded from a keyboard, each of the 64 areas requiring time correction being indicated in turn (Fig. 7 not shown). Correction is in two stages (Fig. 1b not shown): firstly a red and green grid is displayed and toggle switches modify counters storing the 6-bit bytes governing red and green correction currents until in the area considered a yellow grid is seen; secondly a blue grid is added and the same switches move the blue vertically and then laterally to give a white grid, the corrections being stored in a further two counters. The four corrections are recorded in 13 before moving to the next area. The horizontal zones need not contain a uniform 48 lines, and in view of the larger errors at the extremes of the frame scan the uppermost and lowermost zones may contain fewer, e.g. 20 lines. The digital stores 12, 13 may be on a RAM chip.

Pulverized insulating or dispersing agent selected from BaTiO 3 , Al 2 O 3  and SiO 2  having a higher specific resistivity than the semi-conductive material and a higher melting point than the vitreous material may be included. The elements are prepared by mixing pulverized glass whose average grain size is smaller than 1 micron with pulverized semi-conductive metal oxide whose average grain size is less than 5 microns but larger than that of the glass and stirring with a volatile liquid additive such as diacetone alcohol or octyl alcohol until the mixture acquires a sol-like state. The mixture is then applied in the form of a layer preferably by the silk-screen method to the surface of a heat resistive substrate such as iron-plate, glass, ceramics or vitreous material whose melting or softening point is higher than the softening point of the glass in the layer. The layer of mixture is heated at a temperature higher than the softening point of the glass but lower than the melting or softening point of the substrate, thus sealing the layer to the substrate. The heat expansion coefficient of the substrate is preferably approximately the same as that of the vitreous binder. In an embodiment, Fig. 1, a layer of SnO 2 , 103, contained in vitreous binder 102 is formed on the surface of an iron plate 104 which serves as an electrode.
