Title: Method of and apparatus for use in chemical analysis
Inventor: TIPLER GORDON ARTHUR
IPC: G01N33/20
Filed: 1963-01-09
Abstract: 1,005,320. Determining carbon and sulphur in metals. RICHARD THOMAS & BALDWINS Ltd. Jan. 9, 1964 [Jan. 9, 1963], No. 1061/63. Heading B1X. The carbon or sulphur content of individual samples of known weight of a metal is determined by burning each sample with oxygen, collecting all the gaseous products of combustion in a gas-holder with a non-interfering gas so that the gas-holder contains a constant number of moles of gas, and passing part at least of the mixture thus obtained through an infra-red gas analyser specific to the dioxide of the element that is being determined. The apparatus (see Fig. 2) comprises a gas-holder 7 containing a piston 9 capable of being lifted by gas-pressure, an infra-red analyser F specific to the dioxide of the element being determined and arranged to receive gas from the gas-holder, and a pressure-sensitive switch 6 actuated by the pressure of the gas in the holder for closing a valve controlling the supply of gas to the holder. In operation, oxygen from 1 sweeps combustion gases from radio-heating furnace 3 to gas-holder 7. Valves 5 and 10 are actuated by a circuit including electrical contacts 18, 19, Fig. 3, in switch 6, and completed by expansion of the mercury 13. Any change in atmospheric temperature leads to a change in the pressure exerted by the gas in cavity 17, which compensates for the change in pressure in the gasholder ; hence a constant number of moles of gas is collected each time in 7. The rate of combustion of the sample may be reduced by diluting the oxygen supply to the combustion chamber. The sequence once started may be controlled by use of a timing switch.

IPC: C30B25/18
Filed: 1973-01-09
Abstract: 1417484 Epitaxial deposition R C A CORPORATION 9 Jan 1973 [10 Jan 1972] 1107/ 73 Heading B1S [Also in Division H1] The number of lattice defects in an epitaxial semiconductor layer of one material deposited on a monocrystalline substrate due to lattice mismatch is reduced by depositing a series of thin layers, separated by growth interfaces, of a second semiconductor material the lattice of which matches that of the layer, before depositing the layer. The number of sub-layers required depends on the degree of lattice mismatch, the crystalline perfection of the substrate and that required in the epitaxial layer. Simple substrate materials are sapphire, spinel, silicon, germanium, AIIIBV compounds and their alloys and AIIBVI compounds and matching pairs of materials for the epitaxial and intermediate layers are indium arsenide-gallium antimonide, zinc selenide-gallium arsenide, indium aluminium arsenide-indium gallium arsenide, aluminium antimonide-gallium antimonide, aluminium gallium arsenide-gallium arsenide and boron nitride-alumlnium arsenide. The thin layers and epitaxial layer may be deposited by interruptions in known vapour or liquid phase epitaxy growth methods or by combinations of the two methods.

Class 27 Separating, sorting and counting coins and tokens. Coins or similar discs driven (clockwise in Fig. 2) past a counting device 14, 15 by teeth 6a on an inclined wheel 6 operate the counting device only if they are small enough for their inner edges to fall through apertures 11 in contiguous fixed plates 10 beneath the wheel 6: the outer edges of the coins are located radially by resting on a flange 9 (see also Fig. 3) on a fixed plate 7 and the tilted coins are driven by lugs 6b on the teeth 6a. The coins are fed to the wheel 6 through an aperture 8, Fig. 2, in the fixed plate 7 from pockets 5 in a rotating disc 1 lying above the wheel 6 and forming the inclined base of a hopper. After pushing aside a roller 14 to close contacts 16, 17 in a counting device the coins fall through apertures 21 in the base plate 4 into a corresponding shoot. Where coins of several sizes are to be sorted and separately counted the aperture 11 and the counting mechanisms for the smaller coins are passed by the larger coins. A lip 12 on each fixed plate 10 prevents a coin from being forced out of the aperture 11 by the pressure of the roller 14.

Title: Calibration of master oscillators
IPC: G01R23/00
Filed: 1942-01-27
Abstract: 555,008. Adjusting wireless apparatus; indicating-apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and WASSELL, H. J. H. Jan. 27, 1942, No. 1153. [Class 37] [Also in Groups XL and XIX] The calibration of a master oscillator in a wireless transmitter is effected by associating the master oscillator A with a piezo-electric crystal and using it to adjust accurately a further oscillator B to a predetermined reference frequency say 10 kc.) by harmonic comparison. The whole arrangement is such that the master oscillator A freed from crystal control and with its fine tuning adjustment F at zero is set accurately at the lower end of the required range (say 3400 kc.) by the coarse adustment device D and is then adjusted by the fine tuning adjustment F to oscillate accurately at the upper end of the required range (say 2500 kc.) by harmonic comparison with the oscillator B. In this way the cursor H may be adjusted to an appropriate length of scale for co-operation with the scale pointer G the scale being graduated in steps of say 10 kc. The scale may consist of a flat or part cylindrical sheet having a graduated base line and a longer line parallel thereto with the corresponding graduations joined so that an appropriate length say 100 kc. may be selected. A switch E may be provided to associate the crystal with the master oscillator A or the latter with the further oscillator B or with the transmitter to be controlled. The oscillators may be compared by the beat method as by aural means.

Filed: 1938-01-18
Abstract: 504,411. Telegraph exchange systems. TOWLER, E. E. (Siemens & Halske Akt.-Ges.) Jan. 18, 1938, No. 1674. [Class 40 (iii)] To prevent wrong connections by telegraphic impulses following a current interruption or other momentary fault, the connection is released if impulses of different duration from those for setting the selectors act on the selector setting relay. The impulse relay which energizes the selector also energizes a relay Z through a condenser C, which is so dimensioned that the relay Z remains attracted for 35 m. secs. For a dialling impulse of 60 m. secs., z1 interrupts the circuit of a cut-off relay A before the selector relay closes j2, and A does not respond. On the other hand, if the selector relay was energized by a telegraphic impulse of 20 m. secs., j2 is closed while the relay Z is still energized, and a cut-out signal is sent back to the subscriber by a contact a2. According to a modification, the period of actuation of the switching arrangement is determined by the period of response of a slow-acting relay, Fig. 2 (not shown).
