Abstract: 1500547 Detecting the hydrogen content of metal DEFENCE SECRETARY OF STATE FOR 12 May 1976 [19 May 1975] 21313/75 Heading G 1 A [ Also in Division H 1] In a method of detecting the hydrogen content of a piece of metal 1 pulse laser radiation 4 is directed on to the metal. This results in "pulses" of plasma containing hydrogen ions plus ions of any other substances present in the material. The plasma pulses expand and some of it passes through two apertures 7 and 8 to impinge upon a thin foil 9. The foil is within a doughnut shaped support member 10 which is maintained at a negative potential (-25KV). The foil 9 and the negative potential are such that only hydrogen ions striking the foil can penetrate it sufficiently to liberate secondary electrons from the back of the foil. The liberated secondary electrons are detected by the combination of a photo-multiplier tube 13 positioned behind a window 11 having a scintillator layer 12. The whole or a portion of each pulse from the photo-multiplier may be integrated to provide an output whose amplitude is a measure of the hydrogen content.

Filed: 1949-08-23
Abstract: 662,906. Gravity-separation apparatus. HAPMAN, H. W. Aug. 23, 1949, No. 21856/49. Class 46 [Also in Group XXX] A purifying apparatus for, e.g. sedimentbearing coolant liquid comprises first and second settling tanks or compartments arranged in proximity to one another and having a liquid passageway between them remote from the tank bottoms, an inlet conduit extending into the first tank, an outlet conduit extending out of the second tank, and a single sludge-removing conveyer having one course thereof extending across the bottom of the first tank and the other course extending across the bottom of the second tank. Coolant is discharged into a ccnduit 34, Fig. 4, extending the length of a tank wall 17, and passes through a series of holes 37 spaced along the bottom to reduce its velocity. Heavy sediment is deposited in a trough 68 formed by converging bottom walls 25 of a first compartment 23, and the liquid is drawn between baffles 31 and 28 to overflow at 29 into a second compartment 24 by a pump (not shown) connected to an outlet conduit 47. Remaining sediment settles in a trough 67 as the liquid passes under a further baffle 38 which rests on short ledges 41 welded to ends 19, 20, Fig. 2, of the tank and is held between angle members 42 at either end of the tank by a removable channel member 30. Filter screens of conventional type may be provided as an outlet passage 45 if additional sediment removal is needed. The troughs 67, 68, are covered by angle members 69, 70 and joined by a U-shaped conduit 58, these parts being traversed by a flight conveyer 65 (see Group XXX) which passes down a tube 54, Fig. 2, into trough 67, along conduit 58, along trough 68 and up a tube 55, the sediment collected being discharged from the bell-mouthed end (not shown) of tube 55 into a receptacle. Between the open ends of 'tubes 54 and 55 the conveyer passes over a motor-driven sprocket mounted with motor and reduction gear on a slide whose position may be adjusted to take up slack in the belt. The conveyer is caused to traverse the second compartment 24, where relatively little sediment is deposited, before traversing the first compartment 23, to avoid the contamination of relatively pure liquid in the second compartment by sediment from the first that would occur if it travelled in the reverse direction.

Abstract: 423,517. Protective cut-out arrangements. ELECTRICAL IMPROVEMENTS, Ltd., Carliol House, and POYNDER, H. B., 14, Haldane Terrace, both in Newcastle-on- Tyne. Aug. 4, 1933, Nos. 21933 and 28548. [Class 38 (v)] Automatic circuit -breakers.-Relates to overload protective arrangements of the kind in which the trip coil of a breaker is shunted by a resistance, and the shunt circuit is controlled by a thermal or other device so that substantially instantaneous operation on heavy overloads and inverse-time operation for light overloads occurs. To avoid the possibility of the trip coil failing to operate on heavy overloads, due to the increase in its reluctance as its plunger or armature is being raised and to the consequent increase in the amount of current diverted to the shunt circuit, the initial movement of the plunger or armature is arranged to operate an auxiliary switch which controls the energizing circuit of the trip coil to increase its tripping force. As applied to the arrangement disclosed in Specification 389,893, in which the thermal device may be a load-indicating instrument as disclosed in Specification 383,017, the auxiliary contacts are located in the shunt circuit, so as to open @ on heavy overloads and divert all the current through the trip coil, Fig. 1 (not shown). Fig. 6 shows such an arrangement applied to the two-trip-coil protection of three-phase circuits, the current transformers B<1>, B<2>, B<3> being connected in reverse-delta and the trip coils A being connected at one end to the ends of a heating element C and at the other end between two corners of the delta, the third corner being connected to a mid-point tapping of C. The coils A are shunted by the resistances D which are in series with the contacts C<1> operated by C and with contacts E which are opened by A on heavy overload. Fig. 2 shows an auxiliary switch in which the plunger A<2> of the trip coil A normally rests on a contact E<1> and holds it against E<2> which may be adjustable for calibrating A. In another form, Fig. 5 (not shown), the plunger engages one arm of a lever, another arm of which carries the contact, whereas a third arm is acted on by a control spring. In Figs. 7, 8, the coil A operates a change-over switch H so as to increase the tripping current by cutting out some of the turns of the current transformer B and, to avoid open-circuiting of B in doing so, the switch H is constituted by a mercury container pivoted at F<1> and operated by a pin-and-slot connection with A<2>. The latter arrangement is also described and illustrated, Fig. 9 (not shown), in its application to systems as disclosed in Specification 407,454.
