Abstract: 1,174,702. Semi-conductor devices. MOTOROLA Inc. 9 May, 1968 [29 May, 1967], No. 22077/68. Heading H1K. [Also in Division C7] Si or Ge are deposited on sapphire by the decomposition of silane or germane while maintaining the sapphire at 850-970‹ C. for silane and at 550-670‹ C. for germane. After depositing at least 0À2 micron of Si or Ge the sapphire temperature may be raised to 1000- 1300‹ C. for Si deposition or 700-850‹ C. for Ge deposition and the further deposition may be effected with silicon and germanium tetrachlorides and trichlorosilane or trichlorogermane. Deposition is preferably made on the (1012) plane of the sapphire which may first be cleaned by gas etching with ClF 3  in H 2  at 1200‹ C. The epitaxial layer may be doped as it grows by adding phosphine, diborane or arsine to the carrier gas which is H 2 , He or N 2 . Fig. 1 shows a furnace 11, a quartz tube 13, RF induction coils 14 and sapphire wafers 16 on a graphite susceptor 17. A SiO 2  layer may first be deposited on the sapphire by the reaction of oxygen and silicon tetrachloride in the decomposition of ethyl orthosilicate. Selected areas of the SiO 2  are then removed and the Si or Ge are then deposited on the selected areas. The polycrystalline Si or Ge deposited on the remaining SiO 2  layer is then removed by polishing. The structure is used in the assembly of transistors, rectifiers and integrated cir cuits.

Title: Shock-absorber and air spring assemblies

Abstract: 1,207,800. Vehicle spring suspensions. GENERAL MOTORS CORP. 2 May, 1969 [13 May, 1968], No. 22485/69. Heading B7D. [Also in Division F2] A tube-within-a-tube type hydraulic pistoncylinder damper is combined with a pneumatic spring, preferably of the rolling diaphragm type, the gas in the spring being in communication with further gas in an expansion chamber 30. The expansion chamber is contained in the outer tube 8 of the damper 4, a tubular diaphragm 24 forming the dividing wall between the expansion chamber and an hydraulic reservoir 32. The communication between the pneumatic spring chamber (i.e. the chamber bounded by the rolling diaphragm 60 and a tubular cover 2 carried by the damper's pistonrod) and the expansion chamber 30 consists of one or more vent tubes 96. In use on a vehicle, two of the assemblies shown are preferably employed at the rear end of the vehicle; the hydraulic damper damps the vehicle springs, the gas spring " boosts " the main springs and the expansion chamber allows the hydraulic reservoir's volume to vary as necessitated by the piston's reciprocation. However, because of the interconnection between the gas spring and the expansion chamber, there is no pressure difference across the piston-rod seal 40. This is in contradistinction to known hydropneumatic suspension units as depicted in Fig. 5 (not shown).

Abstract: 1474645 Asymmetric square-wave oscillator; pulse modulator KHARKOV POLITEKHNI INST IM VI LENINA 23 May 1975 22645/75 Headings H3T and H4L A square-wave oscillator of the type comprising a cross-coupled pair of transistors 1, 2, Fig. 1, and a saturable reactor 9 linking the two collectors, is made to produce an asymmetric square-wave (i.e. one in which each pulse duration is not equal to each space duration) by tapping the reactor winding and coupling the tap, and the end of the winding, to the collector of transistor 2 via diodes 13, 14, as shown. With this arrangement the "on" time of transistor 1 is the time taken for the current in the left-hand half of the winding to rise sufficiently to saturate the core 11, while the "on" time of transistor 2 is the time taken for current through the whole winding to rise sufficiently to saturate the core- and this time will be shorter than the previous time since the current passes through more turns. In a modification, Fig. 3, the "on" time of transistor 2 is controllable by a signal applied to an additional transistor 19. The result of this is that the right-hand portion of the winding is controllably shunted by transistor 19 thereby, in effect, controlling the effective number of turns through which the current passes.

Abstract: Hydroxy-amines are made by heating equivalent quantities of styrene oxide with a primary or secondary amine of the benzene series, preferably in an indifferent solvent, e.g. xylene.  Acidic or basic catalysts may be present, those specified being sulphuric acid, glacial acetic acid, ammonia and aliphatic amines, which are more basic than the starting amines, e.g. ethylamine.

The dyestuffs dye fibres such as those of acetate silk, nylon, perlon, P.V.C., and polyethylene terephthalate from e.g. an aqueous soap bath.  In examples the reaction product of styrene oxide with (1) p-toluidine is coupled with diazotized p-nitraniline, aniline and  - and b -naphthylamine and tetrazotized benzidine, (2) methyl aniline is coupled with diazotized nitraniline, aniline and benzidine and (3) aniline is coupled with diazotized aniline, p-chloro, -nitro, and 2, 4-dinitro-aniline,   and b -naphthylamine and benzidine.
