An implosion protection barrier for a cathoderay tube comprises a metallic ribbon which is around under mechanically induced tension only at least once around the junction between the faceplate and cone and the tension is maintained in the ribbon until it has been welded to form a complete band such that after the welding and cutting from the remainder of the ribbon the band remains at the same tension as that originally applied. The mountings which support the tube within a cabinet may be bound to the tube by wrapping the ribbon over a part of them. The first end of the ribbon may be welded to one of the supports and after wrapping the ribbon round the tube, which may be done by rotating the tube and feeding the ribbon from a supply through a brake or by rotating the supply about the tube. One welding electrode may be placed on the support to which the ribbon is attached and the other electrode placed on the ribbon. A suitable glueing compound may be applied between the tube and the first layer. In another arrangement of a multilayer winding the first end of the ribbon is not fixed but the first layer is applied with reduced tension which is increased in subsequent layers. In an example 5-10 layers are wrapped one above the other and each layer is about 2À5-3 mm. thick.

Abstract: 1,243,637. Olefin copolymer elastomer compositions. IMPERIAL METAL INDUSTRIES (KYNOCH) Ltd., and D. A. SMITH. 10 Dec., 1968 [29 Dec., 1967], No. 59195/67. Heading C3P. [Also in Division F3] The lining of a case-bonded solid propellant rocket motor comprises an elastomeric-containing compound including 100 parts of elastomer, 40-100 parts of filler material, and 20-80 parts by weight of at least one metal halide having a B.P. above 500‹ C. and developing a significant vapour pressure between 500‹ and 1200‹ C., and which is compatible with the other contents of the elastomer-containing compound. In a typical embodiment, the 100 parts of elastomer consists of 75-100 parts of a terpolymer of ethylene and propylene and a diene containing unsaturated linkages of unequal reactivity (e.g. Shell ECP 900) and 25-0 parts of a chlorosulphonated polyethylene (e.g. Hypalon 40). The filler material is either SiO 2  powder or asbestos, and the chemical compound is PbCl 2 . The latter reduces the transmission of heat from the interior of the motor to the liner at least partly by the barrier effect of the heavy volatiles of PbCl 2  moving in a relatively slow stream along the surface of the liner after release from the liner. The above-described terpolymer results in a low-density liner but if density is relatively unimportant, other elastomers such as nitrile rubbers, neoprene rubbers, chlorosulphonated polyethylene rubbers, styrenebutadiene rubbers, butyl rubbers, polyurethane rubbers, polyisoprene rubbers, ethylene-propylene copolymer rubbers, and silicone rubbers may be used.

Filed: 1970-12-23
Abstract: 1329838 Teaching surface AAI CORP 23 Dec 1970 [29 Dec 1969] 61045/70 Heading F3C A detecting arrangement, for indication of hits, comprises a detector for a target signal, and an analog simulating digital filter signal transmission attenuating unit disposed in signal path intercepting relation to said detector, the attenuating unit having a digital filter signal transmission ratio which varies as a general function of transverse distance from a given selected zero position at the filter. The detector is a photoscope 11, Fig. 1, which detects the ability of an operator to aim at a target T, for example, a tank having a detectable signal generator such as a light beacon L. The photoscope 11 has an objective lens 21 which collects light from the light beacon L, a field mask 31, a filter mask 41, a field lens 51 and a photodiode 61, the light being masked by the field mask 31, filtered by the filter mask 41 and then passed from the photodiode 61 to an indicator 91, via a threshold trigger 71 and an amplifier 81. The field mask 31 has a triangular aperture 33 aligned with a digital-analog filter section 43, 45, Figs. 1 and 4, of the filter mask 41. In use the photoscope is aimed at targets which are a range of distances therefrom and, as the light beacon L is of constant intensity, the light received by the photoscope will vary inversely to the square of the distance of the target 7 from the photoscope. The primary variation of amplitude of the light signal reaching the photoscope 11 from the target 7 and its light beacon L is caused by the inverse square variation as a function of range of the target and this variation is conveyed to the indicator 91.
