Title: Improvements in or relating to ultra-sonic methods and equipment
IPC: G01N29/04
Filed: 1954-04-12
Abstract: 812,332. Ultrasonic inspection devices. LEWIS, E. M., and FOX, J. W. July 12, 1955 [April 12, 1954], No. 20146/55. Divided out of 812,331. Class 118 (2). Apparatus for the examination of material by ultrasonic oscillations in which two relatively movable directional probes are employed is provided with means to indicate the focus or out-of-focus condition of said probes. In a first embodiment observable auxiliary radiation is also directed by the probes and correct adjust. ment for this ensures adjustment for the ultrasonic energy. Two probes 10, 12 carry light projectors 11, 13 respectively (Fig. 1) and the intersection of the light beams indicates the point of focus of the probes. Alternatively a photo-cell 16, or battery of photo-cells, is held in place on the test specimen and its output used to indicate focus of the probes. Special polarizing screens or light filters 14, 15, 17 may be used. The output of the cell may light a lamp, sound an audible alarm or provide a marker pulse on the trace of a cathode-ray tube (C.R.T.). A second embodiment (Fig. 2) utilizes the reflection from acceptable minor discontinuities, e.g. in a weld, to establish correct focus. A trigger unit 20 controls an ultrasonic pulse generator 21 feeding a transmitting probe 22 applied to test specimen 23. A receiving probe 24 is connected to two amplifiers 25 and 26 in parallel. The amplifier 26 is the primary amplifier used for detecting flaws and it may have automatic gain control and/or swept gain. Amplifier 25 is set at a high gain for detection of the minor discontinuities. The outputs of both amplifiers are fed to a C.R.T. 27 having a timebase 28 synchronized from trigger unit 20. A gating circuit 29 ensures that amplifiers 25 and 26 operate on alternate pulses from generator 21, and also controls a step voltage generator 30 to deflect vertically alternate traces on the C.R.T. Thus separate indications are given of the signals from flaws and from the acceptable discontinuities to be used for focusing adjustment of the probes. Instead of the beam switching by generator 30 a double-beam C.R.T. may be used. The amplifier 25 may be gated to show only the minor reflections from the desired range. In a modification only one amplifier is used and the gating circuit 29 controls its gain appropriately for alternate pulses. A further embodiment (Fig. 3, not shown) utilizes different frequencies for detection of the minor irregularities and for detection or examination of flaws. The arrangement is as shown in Fig. 2 but with two ultrasonic pulse generators operating at the different frequencies but at the same pulse recurrence frequency. These are controlled by the gate circuit to emit pulses alternately. Display arrangements are as in the former embodiment.

Title: Improvements in dynamos for train lighting and similar installations
IPC: H02K23/18
Filed: 1922-07-26
Abstract: 205,891. Stone & Co., Ltd., J., and Darker, A. H. July 26, 1922. Dynamos, regulating; exciting.-In a subsidiary-brush dynamo for electric lighting &c., on railway and other vehicles, in which the main brushes rock through the full angle of reversal, the subsidiary brush is fixedly mounted in a different plane from that of the main brushes so that it does not obstruct the motion of the main brushes on reversal, the main brushes being connected by conductor arms with centrally-situated contacts. The subsidiary brush-holder c, Fig. 3, is fixed to the dynamo frame while the main brush-holders b, b<1> are secured to a ring 3 revolubly mounted on ball bearings 4. Electrical connection between the main brushes and the dynamo terminals is effected by conductor arms 13, 15 braced together by an insulating block 16 and engaging with centrally-situated spring- pressed contacts 9, 10. A flexible conductor connects the brush b<1> with the arm 15. Stops are provided for limiting the rotation of the brushes in either direction. In order to make full use of the commutator for the working current, there may be provided on the commutator additional main brush-holders secured to the frame of the machine. On each of these brush-holders there is provided a projecting spring contact with which engages a corresponding projection on the movable brush-holder. The projections are so disposed relatively to the brushes that when they are in contact the stationary and movable brushes are in alignment. The projections may be made of phosphor bronze and may act as the stops for limiting the rotation of the brushes. If desired, electromagnetic means may be employed for retaining the fixed and movable brushes in alignment and contact. In the lighting and battery-charging system shown in Fig. 1, in which the dynamo is fitted with the brush-rocking arrangement according to the invention, the main field winding d is connected in parallel with a variable resistance f in the lamp circuit l, and a demagnetizing winding e is connected between the subsidiary brush c and the negative main brush b<1>. An auxiliary field winding t is also provided which normally assists the field winding d, the winding t being normally connected between the auxiliary brush c and the negative brush b<1>. When the battery s is fully charged, the switch o operates to disconnect the winding t from the negative brush b<1> and connect it to the positive brush b so that the winding t opposes the main winding d. A short-circuit across a resistance n connected in series with the lamps l is broken when the main switch j closes.

Title: A method for the purification and concentration of carboxylic acids
IPC: B01J41/04
Filed: 1957-06-28
Abstract: A method for the purification and concentration of crude carboxylic acids, particularly hydroxy-acids, comprises bringing a dilute aqueous solution of the carboxylic acid into contact with a basic anion exchange in the OH-form, eluting the carboxylic acid anions from the anion exchange by means of an aqueous elutant which comprises an acid which, at a temperature in the range between room temperature and the boiling point of the eluted aqueous solution of the carboxylic acid, can itself be volatalised from said eluted aqueous solution, or forms a gaseous anhydride which escapes from said eluted aqueous solution in this temperature range, and mainly regenerating the exchanger to the OH-form by treatment with hot water or steam.  Suitable eluting acids include carbonic, sulphurous and formic acids.  The eluting acid may be produced during the elution, e.g. by eluting with water and at the same time introduring the gaseous anhydride of the eluting acid, possibly under pressure.  The anion exchanger is generally an anion exchange resin, usually containing primary, secondary or tertiary amino groups, but not usually the strongly basic quaternary amino groups.  The hot water or steam-regenerated exchanger may be completely converted to the OH-form with alkali. In examples, citric acid and tartaric acid are purified.
