Title: Improvements in or relating to the manufacture of rod-shaped silicon monocrystals
IPC: C30B15/20
Filed: 1967-06-12
Abstract: 1,140,656. Crystal-pulling. SIEMENS, A.G. 12 June, 1967 [13 June, 1966], No. 26960/67. Heading B1S. A rod of silicon uniformly doped with antimony is pulled from a melt having a predetermined antimony content in an argon atmosphere at subatmospheric pressure, the pressure being such that the evaporation of antimony from the melt prevents an increase in the antimony content of the melt as pulling proceeds. The pressure may initially be 10 mm and may be held at this value or reduced to 3 mm. The silicon is initially melted at 1400-1450‹C preferably at a pressure less than 10-4 mm. Hg. The temperature of the melt is then reduced until the melt is barely liquid and argon is introduced to raise the gas pressure to about 500-760 mm. Hg. The antimony is introduced before or after immersion of the seed crystal in the melt and the pressure is then set at 10 mm. Hg and maintained constant while a flow of antimony takes place, or reduced to 3 mm. Hg. The silicon/antimony melt may alternatively be produced by melting a silicon/ antimony alloy at a pressure of about 760 mm. Hg. In the figure a seed crystal 1 is accommodated in a reaction vessel 10 and is attached by means of a mounting 2 and intermediate element 3 to a drive arrangement which spins the seed crystal 1, together with the monocrystalline Si rod developing from it, about its longitudinal axis at a rotating speed of 10 to 100 r.p.m., the crystal being drawn from the melt 5 contained in a quartz crucible 6 located inside graphite crucible 7 which is heated by means of a high frequency coil 8, the heating effect of the coil being re-enforced by a concentrator 9 surrounding crucible 7. The temperature of the melt 5 is determined by a Pt/Pt-Rh thermocouple 11 connected to a circuit which controls the power supply of coil 8. A tubular crucible mounting 14 and rodtype concentrator (9) mounting 15 are passed through baseplate 13 through which an inlet connection 16, to allow influx of the protective gas from supply vessel 17, also passes. The cover 20 is provided with a cooling jacket 19. Pumps 25 and 26 serve to reduce the pressure in the reduction vessel.

Title: An electric guard circuit
Inventor: JOHNSON BENJAMIN BERTIE
IPC: H04Q3/00
Filed: 1956-09-04
Abstract: 824,957. Automatic exchange systems. TELEPHONE MANUFACTURING CO. Ltd. Aug. 26, 1957 [Sept. 4, 1956], No. 27077/56. Class 40 (4). Apparatus responsive to a calling condition on any one of a number of lines is guarded against prolonged accidental busying by guard circuits which energize automatically a predetermined time after the apparatus has been taken into use to render it available again for further calls. The line-finding system described uses bar-relays of the finger magnet type referred to as selective relay units SRU1-SRU4. The subscribers' lines are arranged in pairs, each pair sharing a line relay such as LS 1.6. The line relays are grouped in fives, each five sharing an initiating relay such as G1, Fig. 3. Only one of the initiating relays G1-G4 associated with a set of selective relay units SRU1-SRU4 can be energized at one time. If subscriber L1 or L2 calls line relay LS 1.6 operates to energize the first finger magnet in FMPR1, Fig. 3. The finger magnet interposes a finger between the main armature of SRU1 and the related column of contacts. The line relay also energizes the first initiating relay G1 which holds. If the trunk is free TA1, Fig. 4, pulls up. If the trunk is busy TA2 energizes. Assuming the trunk is free TA1 seizes a register by the operation of RA (not shown) which energizes the main magnet PR1 of the SRU1. The calling line is thus connected to the trunk and relay A (Fig. 2) energizes. A operates B to energize K1 or K6, depending on which of the two lines is calling, so restoring the line relay LS 1.6, which releases the initiating relay G1. Fault. If, due to some defect, G1 remains operated then none of the other initiating relays G2-G4 can energize. This fault is overcome by a guard circuit. A predetermined time after the operation of G1 a thermistor TH1 permits guard relay GB1 to energize over its upper winding. GB1 then locks up over its lower winding and opens the holding circuit of G1 at gb(1) 1. GB1 supplies tone to the calling line and remains operated until the calling subscriber hangs up.

Patent GB-272528-A (GB)
Abstract: 272,528. I. G. Farbenindustrie Akt.- Ges. June 9. 1926, [Convention date].. Samples furnished. Ferylene derivatives. - Perylene carboxylic acids, their imides and halogen substitution products, are decarboxylated by heating them under pressure in aqueous solution or suspension in the presence of an acid-binding agent, or by heating their salts under pressure in neutral or alkaline aqueous solution or suspension. By selection of the reaction conditions, the degree of decarboxylation can be regulated; for this purpose the use of an excess of alkali has the same effect as raising the temperature or increasing the concentration. Thus, from perylene-3 : 4 9 : 10-tetracarboxylic acid are obtained the 3 : 4: 9-tricarboxylic acid, the 3 : 9- or 3 : 10-dicarboxylic acid, the 3-monocarboxylic acid, and finally perylene itself, and examples are given of their preparation. Similarly, perylene-3 : 4 : 9 : 10-tetracarboxylic acid monoimide yields either the 3: 4-dicarboxylic acid imide or a dicarboxylic acid, the imide ring being ruptured in the latter case, whilst perylene-3 : 4- dicarboxylic acid imide gives the 3-monocarboxylic acid: wording conditions are given for these reactions. In the case of chlorinated perylene carboxylic acids, the decarboxylation is generally accompanied by replacement of the chlorine by hydroxyl groups. Perylene-3 : 4 : 9- tricarboxylic acid readily forms both an imide and an anhydride. The products are useful as intermediates for the manufacture of dyes. Specification 221,008 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to the decarboxylation of derivatives and substitution products in general of perylene carboxylic acids; this subject-matter does not appear in the Specification as accepted.
