Title: A new or improved method of coating metal surfaces
Inventor: SACHS KURT
IPC: C23C24/00
Filed: 1963-03-29
Abstract: <PICT:1087291/C6-C7/1> A metal surface such as a steel wire is coated with another metal such as Al, and/or Zn by forming an insulating coating on the particles of the coating metal, electro-statically charging the coated particles which are then applied to the metal surface, the insulating film then being ruptured or dissipated to ensure metal to metal contact and heating the coating metal during or after its application to improve the adherence of the metal particles.  The metal particles e.g. Al of minus 200 mesh may be coated with a wax film by ball milling or a film of aluminium nitride or oxide may be formed during the production of the powder.  The electro-static charge is applied to the powder either by an electro-static spray gun or by passing the steel wire to be coated through an electro-static fluidized bed of the powder. After coating, the insulating film may be dissipated by heating in the case of the wax or may be ruptured by compaction e.g. rolling or swaging in the case of the oxide and nitride.  The heating may be sufficient to fuse the coating or merely to sinter the coating and the rolling or swaging may be hot or cold.  As shown in Fig. 1 a steel wire 11 is drawn through two pairs of rolls 13 and 14 which are resistance heated via 15.  The wire enters a fluidized bed 16 through which air or an inert gas is passed, the fluidized bed containing wax coated particles of Al.  Current is supplied to the bed via grid electrodes 21 and leads 23 and the other side of the current circuit is connected to earth and thus to supply reel 12 and/or rolls 13.  The heating of rolls 13 and 14 and the position of the bed in relation to the rolls is adjusted so that the wire attains a temperature high enough e.g. 220 DEG -320 DEG  C. between the bed 16 and rolls 14 for the wax to be volatilized.  The coated wire is then rolled preferably at 350 DEG C. in rolls 14 and 24, the roll axis of each pair being at right angles to one another Fig. 3 (not shown). The compacted coating is then sintered at 500 DEG C. in the case of aluminium.  To prevent oxidation of the coating the wire may be enclosed in an inert or nitrogen atmosphere between the bed 16 and the rolls 14.  In a separate embodiment the wire may first be passed through a molten bath of the coating metal and then charged insulated metal particles are then applied to the fused layer.

Title: Improvements in or relating to the measurement of radioactive decay rates
Inventor: MACKENZIE ALASDAIR
IPC: G01T1/30
Filed: 1962-04-04
Abstract: 965,334. Monitoring radio-activity. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 20,1963 [April 4,1962; July 30, 1962], No. 29156/62. Heading G1A. [Also in Division G6] A radio-activity decay rate measuring apparatus comprises a sample chamber, means for isolating a sample admitted into the chamber, a radiation measuring device adapted to provide an electrical output representative by its magnitude of the radio-activity of a sample isolated in the chamber, an electrical storage means, a timing means responsive to isolation of the sample for . causing after a predetermined delay the storage in said storage means of an electrical value dependent on the instantaneous output of the measuring device, comparison means for comparing the stored value with the succeeding output of the measuring device, and means actuated by the comparison means for providing a signal indicative of the relationship between the stored value and such succeeding output. In the arrangement shown gas to be monitored normally passes through a pipe 12 past a scintillation counter 16 arranged to detect radiation in the energy range 2-5 Mev. and to provide an output to amplifier 31 and ratemeter 32. To make a measurement relay 40 is energized by a manual key 54; relay 38 is normally energized, but if the output of ratemeter 32 rises above a fixed value the double triode 35 changes state and de-energizes relay 38. As a result of relay 38 opening, valves 14 and 15 in pipe 12 are closed to isolate a sample of gas in the pipe, a clock motor 50 is started, and after a short delay a slow release relay 39 is opened and the instantaneous output of ratemeter 32 stored in storage unit 36 is isolated from the ratemeter. Half the value stored in unit 36 is applied to a grid of double triode 37 through a resistance chain 46, 47. The other grid of valve 37 is connected to ratemeter 32, so that when the output of the ratemeter falls to half its original value, triode 37 changes state and deenergizes relay 48. If this happens before the clock motor 50 opens contacts 52, i.e. if the halflife of the radio-activity is less than a predetermined value, lamp 5, which was lit as a consequence of the de-energization of relay 38, remains lit to indicate that no fission products are present in the gas sample. If contacts 52 open before relay 48 is opened, lamp 5 is extinquished and lamp 6 is lit to indicate that the gas contains fission products. In a modification, Fig. 2, (not shown), the ratemeter 32 is logarithmic and its output at the start of the monitoring period is stored on a condenser, and the charge on the condenser is then reduced by a fixed amount corresponding to division by two on the logarithmic scale. At the end of the clock period the charge on the condenser is compared with the current ratemeter output, and a relay opens or not according to which is the greater. Specification 960,226 is referred to.

Abstract: 881,986. Force-measuring devices. ALLMANNA SVENSKA ELEKTRISKA A.B. April 13, 1960 [April 16, 1959], No. 13144/60. Class 40 (1). [Also in Groups XIX and XXXIV] Force-measuring load cells are supported in circumferentially disposed apertures in an annular body so that the sensing direction of the elements is parallel to the axis of symmetry of the body. In Figs. 1 and 2 three measuring elements are mounted in apertures 2 which pass from the inner edge to the outer edge of a circular annular body 1. The body is supported by projections 7 and the elements will measure the force exerted on the base 10, e.g. by loading of the body. These elements are preferably of the magnetostriction type (e.g. as in Specification 767,791), and to ensure that they operate on the linear part of their characteristic they are mounted in a pre-stressed condition, e.g. by distortion of the sides of the apertures before the elements are fitted. Overload stops can be provided to limit stress of the elements in operation (Fig. 3, not shown). In a modification (Fig. 4, not shown) the apertures reach one face of the annulus and thus constitute channels in the face which are covered by a separate plate mounted underneath the annulus. Such plate, or at least the parts which close the apertures, is made thin and resilient to apply the load to the measuring elements. The apertures may open out to channels only at the outer edge of the annulus. To measure the axial thrust in bearings (Fig. 5) two annular bodies 18 and 19 are provided, the first of these being fastened to the bearing support and having a circumferential recess to engage the measuring elements 21. The latter are mounted on a flange 24 attached to the body 19, which is prevented from rotating but is displaced longitudinally by the thrust to be measured. This is effected by means of a flange 30 on the shaft 29 and blocks 31 equal in number to the measuring elements. The continuous recess in the body 18 may be replaced by a separate recess for each measuring element, in which case the flange 24 is broken up into a number of projections. The body 18 carries overload stop surfaces 33 which also permit the bearing to be used without the measuring elements being in position. Removal of these is facilitated by arranging for the flange 24 to be detachably secured to the body 19. The measuring elements may be seven in number (Fig. 6, not shown).
