Abstract: 1,013,818. Radiation vacuum gauges. UNITED STATES ATOMIC ENERGY COMMISSION. April 16, 1963 [June 6,1962], No. 14815/63. Heading G1A [Also in Division H1]  A radiation vacuum gauge comprises means for exciting residual gas atoms by electron interaction therewith to produce light quanta, and means for observing said light quanta as a function of the gas pressure. The vacuum system being gauged, 11 includes an electron gun 13 which projects a beam of electrons across a test region 24. Excited atoms radiate light quanta, which are detected by a photomultiplier 31 the output of which is recorded. To reduce noise effects, the electron gun is fed from a pulse generator 23 and a filter 34 is tuned to the pulse repetition frequency. Optical filters 32 may be used to select particular emission wavelengths for the investigation of partial pressures.

Title: A new or improved accelerometer
IPC: B64D45/00
Filed: 1961-04-25
Abstract: 980,492. Measuring acceleration electrically. SVENSKA A.B. GASACCUMULATOR. April 25, 1961 [April 25, 1960], No. 14893/61. Heading G1N. Linear acceleration is measured by an eccentric mass spring mounted on a rotating disc so that the mass performs an oscillatory movement as centrifugal acceleration adds to or subtracts from the linear acceleration of the body. A side view of the device is shown in Fig. 1. Mass 14 is eccentrically mounted on a wire 13 carried between springs 11, 12 attached to the edges of rotating disc 10. Also carried on the same wire is one element 15 of an E-type transformer the base of which is mounted on the disc. The disc is driven at constant speed by motor 20. Linear acceleration alternately adds to and subtracts from centifugal acceleration so that the output of the E-type transformer is an A.C. envelope which in the absence of linear acceleration is as shown at 22 in Fig. 2 but in its presence is as shown at 24. The modulation depth is a measure of accleration and its direction can be determined by means of a reference generator 26. Fig. 3 shows an assembly with two arrangements at right angles to give, say, NS and EW accelerations. These may be determined by the output from the E-type transformers through inductive pick-offs one half of each of which is mounted on the rotating disc and the other part on a gyro-compass so that the EW-NS accelerations are given directly. Figs. 5 and 6 show the outputs of the pick-offs respectively for non-linear and for linear accleration. Comparison (in Fig. 6) of the amplitudes during consecutive half-cycles gives acceleration directly. Alternatively, the number of pulses in the two half-cycles may be counted by a circuit which subtracts the totals giving accleration directly (Fig. 8 not shown). In modifications (Figs. 10-12, not shown) two parallel coupled arms are provided each carrying a displaceable mass or two masses may be connected to the junction of a four spring system and a pneumatic or hydraulic restraint may replace the resilient spring arrangement. Mercury may be used for the masses.

Filed: 1968-03-28
Abstract: 1,186,793. X-ray measurement of moisture content. VALMET OY. March 28, 1968 [April 1, 1967], No. 14949/68. Heading G1A. The moisture content of a travelling web such as a paper web is determined by X-ray absorption, an X-ray detector being placed on one side of the web together with a radio-active source whose radiation passes through the web to excite X-rays from a plate on the opposite side, the X-rays then return through the web to the detector. Depending upon the intensity of the radio-active source which is decided by the web thickness, the primary radiation absorption by the moisture may form part of the measurement. The plate which may be of calcium carbonate may be a normal part of a paper making machine. The X-ray detector which may be proportional or scintillation counter is shielded from primary radiation direct from the source but back scattered primary radiation is discriminated by pulse height analysis or the use of Ross filters.

IPC: G05D23/275
Filed: 1962-04-18
Abstract: 982,096. Automatic temperature control. SATCHWELL CONTROLS Ltd. July 18, 1963 [April 18, 1962], No. 14966/62. Heading G3R. Apparatus for controlling the temperature of an electric cooking oven 1 comprises an electric heater 2 connected to a power supply by way of a thermostatically operated switch 3 and a second switch 5 which is located outside the oven 1, the switch 5 being operated by a motor 9 which is controlled by a time operated switch 11. The duration of a cooking period is set by a timer means which retains the switch 11 open during the cooking period and the switch 5 then remains closed so that the energization of the heater 2 is controlled by the thermostatic switch 3 to maintain the oven temperature constant at the value set on the thermostat. At the end of the cooking period the timer means causes the switch 11 to close and adjusts the thermostat switch 3 to a lower temperature setting. Closure of the switch 11 causes the motor 9 to run which causes the switch 5 to be opened and closed in a cyclic manner. Thus after the end of the cooking period the heater 2 remains energized but at a reduced value.

Title: Method of and apparatus for extracting aromatic amines from the reaction mixtures from bechamp reductions
Filed: 1954-05-26
Abstract: <PICT:0754024/IV(a)/1> An aromatic amine is extracted from the reaction mixture from a Bechamp reduction, by a method wherein the reaction mixture is extracted with a solvent suitable for the amine in question and wholly or partly immiscible with the reaction mixture, characterized in that the reaction mixture is kept at rest or substantially at rest while the solvent is introduced into the reaction mixture in a finely divided state and allowed to rise through the reaction mixture at such a speed that no movement in the mixture as to occasion emulsion phenomena is produced.  The apparatus used may comprise a tower, a spreader plate at the bottom of the tower and a coil fixed to the lower side of the plate, both coil and plate being perforated, and the arrangement being such that solvent led into the tower is forced to circulate through the coil and to issue from the perforations as jets.  The extraction may be carried out in the apparatus shown in Fig. 1. On completion of reduction the mixture (i.e. amine, iron oxides and water containing dissolved salts) is transferred via inlet 2 to the jacketed tower 1.  Solvent from the tank 9 is introduced at the bottom of the tower, where it is finely divided by the device shown in Fig. 2-This comprises a bottom plate 21 with a welded on semi-tubular coil 22, the plate being perforated.  A textile cloth 23 impermeable to the solid particles in the mixture, a wire gauze 24 and a grating 25 are applied thereto and the whole is fitted to the bottom flange of the tower.  Solvent is pumped in simultaneously at the centre and at the exterior end of the coil, and rises through the mixture.  As it rises up the tower the solvent forms a more or less homogeneous phase, and leaves the tower via 3.  Water is separated out in tank 10 and the solvent containing dissolved amine is recirculated via tank 9.  The solvent is circulated until it is saturated with the amine, then it is withdrawn from the system and replaced by fresh solvent, the process being repeated until extraction is complete.  In examples (1) a reaction mixture containing p-aminobenzoic acid ethyl ester is extracted with toluene as described above; (2) a reaction mixture containing p-aminodimethylaniline is extracted with trichloroethylene.

By contact with the rollers, the cakes are inverted in position during the succeeding part of their travel.  Alternatively, instead of rollers, a rotating member provided with wing-like boards 10, Fig. 6, suitably disposed as to engage the cakes, may be employed.  The machine may be provided with one or more pairs of rollers 12, 14 between which the cakes pass during the initial part of the travel, and so disposed as to convert the originally circular cakes into bodies of the requisite flattened form.  The rods 2 on which the cakes are suspended, may be supported in sockets 4, Fig. 3, projecting from the sides of the chains; or they may be passed through the hollow chain pins 5, Fig. 4.  At the points where the cakes are placed in and removed from the machine, glass walls 16, 17, Fig. 1, are provided for the purpose of protecting the operatives from the treatment liquids.  The treatment liquids may be supplied through spray pipes 18, 19, Fig. 1, arranged as shown or situated vertically above the cakes so that the liquid falls from one row of cakes on to the row lying underneath.  Alternatively, the cakes may be allowed to dip into vats while at the lower points of the travel. When the cakes have to be treated with a number of different liquids, then a single chain track may carry the cakes through all the treatment baths, or one chain track may be used for one or a few treatments and the rods transferred to a succeeding chain track for the continuation of the treatment.

Abstract: 213,213. Erste Br³nner Maschinen-Fabriks-Ges. March 22, 1923, [Convention date]. Rotors ; arrangement of bearings.- In a steam or gas turbine, the gland diameter d at the high-pressure end is smaller than the gland diameter d<1> at the low pressure end, and both these diameters d, d<1> are less than the bearing diameters d<2>, d<3>. The shaft diameters between the rotor wheels r progressively increase from d to d<1> from the high pressure to the low pressure end of the turbine. To prevent undue deflection due to decrease in shaft diameters, extra bearings are provided, as, for example, by a suitable modification of the thrust bearing k. For ease in dismantling, special bushes may be mounted on the shaft to give the requisite bearing diameter.
