Title: A penetrant method of flaw detection and penetrant therefor
IPC: G01N21/91
Filed: 1961-08-31
Abstract: A self-developing penetrant liquid for flaw detection comprises a tracer, e.g. fluorescent or coloured, and a vehicle in which the tracer is solvated, the vehicle being a liquid capable of wetting and spreading on the surface of a test body and of entering any surface openings of any flaws present in the test body, the vehicle being also capable of exuding from the flaw openings and of being converted into a substantially immobile mass containing the tracer in solvated form on the application of energy, preferably heat energy, to the vehicle.  The tracer, if coloured, can be as described in Specification 684,021.  Fluorescent tracers can be a dye, dyestuff, dye intermediate or petroleum fraction soluble in the vehicle.  A specific fluorescent tracer described is Fluoral 7GA (a naphthalimide oil-soluble dyestuff) and 4-methyl, 7-diethyl-amino coumarine.  The liquid can contain a wetting agent which is non-ionic or anionic having associated lipophilic or lipphobic groups and can be a non-ionic alkaline organic phosphate ester, a condensation product of ethylene glycol with an alkyl phenol, or a soap of a long-chain unsaturated mono-carboxylic fatty acid.  The vehicle can comprise two components, one component being a liquid and the other forming a colloidal dispersion in the liquid component, each component having a low vapour pressure such that on application of heat neither volatilizes appreciably.  Alternatively the vehicle can comprise two components at least one of which is a liquid, the two components forming a solution and one component having a vapour pressure such that on the application of heat it evaporates substantially entirely, leaving a substantially immobile mass. The latter component can be an organic solvent such as an alcohol and/or water.  Two components forming a gel are also referred to. General specific examples of the vehicle are described.  The energy applied to the vehicle is preferably heat energy by convection, conduction and/or infra-red radiation, or by alternating induced electric current in the case of electrically conductive test bodies, or by ultra radio irradiation in the case of plastics and non-metallic test bodies.  Light energy in place of or in addition to heat or other energy can be used in the case of vehicles containing a substantial proportion of gelatine or similar materials which harden upon exposure to light. Electron discharge, X-ray and shorter wavelength radiant energy can be used where a principal component of the vehicle is a low molecular weight polyolefin liquid or solution which hardens in response to such energy. Specification 642,402 also is referred to.

Title: Improvements relating to analogue to digital converters
Inventor: EDWARDS JOHN RONALD
IPC: H03M1/00
Filed: 1963-08-09
Abstract: 1,098,172. Electric selective signalling; decade ring counters. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 6, 1964 [Aug. 9, 1963]. No. 31480/63. Headings G4A and G4H. In an analogue-to-digital converter of the balancing type, the comparator controls the size of the steps in which a bidirectional multiorder digital counter is incremented/decremented. The A.C. or D.C. input analogue voltage is compared at 1 with a reference analogue voltage from digital-to-analogue converter 2 the input of which is the reading of a counter 3. Means 4 determines which comparator input is the greater, and means 6 (utilizing a Schmitt circuit) determines whether the error exceeds a predetermined threshold. The outputs from means 4, 6 control diode gates in means 5 to route clock pulses to the count up or count down input of either the hundreds or the units decade of counter 3 until balance is obtained at comparator 1 or the counter 3 reaches one of its limits (see below). Digitalto-analogue converter 2 may be a tapped transformer in the A.C. case. As a modification counting pulses may alternatively be fed directly to any decade. Counter (Fig. 4, not shown). The counter has four decades with inter-decade carry, each decade being of conventional ring type utilizing silicon-controlled-rectifiers. As stated above, pulses to be counted may be routed to the count up or count down line of either the units or hundreds decade (or others possibly). Diode AND-gates controlled from the counter stages prevent the counter overrunning 9999 (counting up) or 0000 (counting down) by cutting off the counting pulses at 5, Fig. 1.

Title: Improvements in or relating to endless band conveyors
IPC: B65G17/06
Filed: 1952-12-12
Abstract: 735,340. Endless conveyers. STEINKOPF, W: Dec. 12, 1952 [Dec. 15, 1951; March 13, 1952; April 1, 1952; June 13, 1952], No. 31604/52. Class 78 (1). An endless conveyer comprises a series of plates 12, 13, Fig. 3, carried on supports 3, Fig. 1, extending between transverse shafts 1 carried by an endless chain 8, each end of each support being arranged between convex surfaces 5 on the respective shaft for lateral swinging of the support with respect to the shaft and being also adapted for longitudinal displacement relative to the shafts. Preferably, the longitudinal displacement is effected by slotting the end holes in the supports 3 for receiving the axles. Guide-members 9 on the axles co-operate with a guide-rib formed on the track (not shown) for supporting rollers 2 on the ends of the axles. The supports each comprise three parts hinged together for movement of their hinge points 7 only upwards relative to the aligned position, whereby a firm surface is provided for the conveyer plates which are placed one on each part of the supports 3. The plates may be interconnected by concertina members 14, Fig. 3, for negotiating curves. In an alternative form the pairs of supports between each pair of adjacent axles may be arranged convergingly. In a further form, Fig. 5, the supports 25 may be rigidly attached to one of the adjacent axles 23 and have a slotted connection with the other at 27, the axles 23 being of oval cross-section. Further flexibility is obtained by having a loose pin-and-slot connection between the parts of the supports so that these may swing also in the plane of the band. The supports 25 may also be telescopic. Lateral guiding is effected by rollers 28 on vertical axles secured to the conveyer plates and engaging a vertical portion of the supporting track for the rollers 2. Thus discharge can be effected by guiding the band from horizontal to vertical disposition and twisting it back after discharge.

Title: Improvements in or relating to means for regulating direct current machines
IPC: H02P7/26
Filed: 1923-12-17
Abstract: 234,146. Rushen, P. C., (Siemens- Schuckertwerke-Ges.). Dec. 17, 1923. Exciting.-The speed of a continuous-current machine is maintained constant by exciting the, field with an electron current controlled by two factors, one depending on the speed of the machine.. and the other depending on an additional adjustable. voltage. A continuous-current motor 1, Fig. 2, has a shunt field winding 2 and a separate winding 3 acting in the same direction and fed from the mains through a thermionic valve. In the circuit of the valve grid 6 there are connected a tachometer dynamo 7 driven by the motor and an adjustable opposing battery 12. The voltage of the battery 12, and the rheostats are adjusted so that at the desired speed a mean current flows through the winding 3. An increase of motor speed results in an increased potential of the grid 6 and the motor slows down again owing to the greater current in the winding 3. The speed of the machine may be varied by a simultaneous adjustment of the rheostat 8 in the main field circuit and the voltage of the battery, and the speed is kept automatically at this value. In the arrangement shown in Fig. 5, the motor 1 has constant excitation due to the winding 2, and the speed is varied by altering the voltage EB applied to the brushes. The adjustable voltaga opposing the tachometer-dynamo voltage may be obtained by tapping off a portion of the applied voltage E<B>. In the case of a motor adapted for speed regulation on the Ward- Leonard principle, the opposing voltage may be tapped from the terminals of the generator field winding. A magnetron may take the place of the electron tube shown.

Abstract: 505,910. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., ROBB, J. G., FURNIVAL, J. M., and WITT, B. J. Nov. 18, 1937, No. 31764. [Class 40 (v)] Relates to means for preventing the production of "false" guiding-lines due to the presence of subsidiary lobes, such as l1, l2, l3, Fig. 1, in the two main beams of an equisignal navigational system. According to the invention, the subsidiary lobes of each main beam are segregated by means of a reflecting array so that all these carrying say the " dot " signal fall to one side only of the main guiding line, whilst those carrying the " dash signal are thrown to the opposite side. In this way, the dots and dashes of the auxiliary lobes cannot merge to give a false equi-signal indication to the side or rear of the main beam. As shown in Fig. 3, each of the two main beams is produced by a series-phase aerial array A1, A2 of the kind described in Specification 403,949, and a central line of half-wave reflectors R is arranged to segregate the auxiliary lobes as described. The reflectors R also serve to " sharpen " the main guiding-line.
