Patent SE-338594-B (SE)
Inventor: MCGRODDY J
IPC: H03B9/12
Filed: 1968-05-22
Abstract: 1,217,522. Semi-conductor oscillators. INTERNATIONAL BUSINESS MACHINES CORP. 4 April, 1968 [14 Aug., 1967], No. 16232/68. Heading H3T. [Also in Division H1] An oscillator uses a body of a semiconductor material which at least in certain crystallographic directions has the drift velocity applied field relationship shown. In the embodiment the body is of germanium doped with antimony or bismuth and is provided with two non- injecting contacts such that the field is applied in a (100) direction. The contacts are of soldered or alloy type and include diffused or alloyed terminal regions of the same conductivity type as the centre of the body. To obtain oscillations the voltage applied to the two contacts must exceed a threshold voltage v 1 ; above this threshold oscillations categorized as Type I occur until a voltage v 2  is reached when they cease. Type II oscillations occur in a higher voltage range v 3  upwards, the upper limit of this range being made less than the voltage which produces avalanche breakdown of the body. For many devices v 2  = V 3 . Within the lower part of the range v 1 -v 2  the frequency increases slightly with voltage; at a certain point it jumps by a factor of about 2 and then again, in the upper part of the range, increases slightly with voltage. With some of the devices the v 1 -v 2  range is split into three parts: high v; low v; high v. The Type IT oscillations, which occur at roughly a tenth of the frequency of the Type I oscillations, are believed to arise from a minority carrier mechanism involving periodic local avalanching (resulting from impact ionization) but not total breakdown. Type II operation is favoured by using lower temperatures. At very low temperatures and at voltage above v 1  a crystal length-dependent Type III oscillation may occur which involves a domain propagation mode which, like the other modes, is not, however, thought to involve an inter-valley transfer mechanism. The preferred geometry for Type I operation is described by Fig. 11A (not shown) and that for Type II operation by Fig. 11B (not shown). The shape of Fig. 11C (not shown) allows Type I oscillation to take place at a lower v 1  than for an otherwise similar uniform body but leads to a lower amplitude of oscillation and polarity dependant operation. The oscillators may have resistive or reactive loads; the latter may be tuned and though shown in Fig. 1A as comprising discrete components may instead be a cavity or waveguide completely or partially containing the semiconductor device to which it is electromagnetically coupled. Tests show that the oscillations are pressure-dependant, through this fact is not made use of in operation of the embodiments.
Patent SE-335138-B (SE)
Inventor: BARKER R
IPC: C07C209/18
Filed: 1963-08-12
Abstract: Aminated benzenes are produced by contacting a hydroxybenzene with an aminating agent in the presence of a catalyst selected from silicaalumina, zirconia - alumina, titania - alumina, phosphoric acid and tungsten oxide, at a temperature between 300 DEG  and 600 DEG  C. and under superatmospheric pressure.  Hydroxybenzenes are defined as phenol and substituted derivatives, where one or more of the ring hydrogens is replaced by an aliphatic or aromatic group or both.  The aminating agent is preferably ammonia but ammonium chloride, ammonium carbonate, and hydrocarbon substituted primary and secondary amines, such as methylamine, and N-methylaniline, may also be used. Thus aniline may be produced by contacting a mixture of phenol and ammonia containing 1/2 to 40 mols. of ammonia per mol. of phenol with a silica-alumina catalyst at a temperature of from 350 DEG  to 500 DEG C. and a pressure of at least 7 atmospheres. Regeneration of the catalyst with an oxygen-containing stream is facilitated by the incorporation of cerium and metals of Groups Vb, VIb and VIIb, such as vanadium and tungsten, or their salts and oxides into or upon the catalyst.

The calibrated and dimensionally stabilised multi-cell profile is again heated at the contact surfaces to the welding temperature of the thermoplastic material. The butt weld between the windings is welded under an axial pressure below the critical pressure for dimensional stability. - Extrusion dies for carrying out the method are also specified.
