Abstract: 1,053,654. Automatic circuit-breakers. FEDERAL PACIFIC ELECTRIC CO. May 21, 1963 [May 21, 1962], No. 20252/63. Heading H2B. A multipole circuit breaker has a bimetal 24 in each pole to operate a common trip bar 70 in response to an overload and also has a magnetic tripping device, said device comprising a channel-shaped core 86 behind each bimetal 24 and a double-ended armature 98 mounted between the bimetal 24 and the trip bar 70 for rocking movement from its normal position where end 98a of the armature has a magnetic back-pull toward a pole face 94a at low current levels and where end 98b moves towards the core 86 at higher current levels such that end 101 of the armature operates the tip bar 70 to free a latch 61, which in turn rotates and releases cradle 46 with consequent collapsing of the toggle mechanism 38 and opening of the breaker contacts 16, 18. Adjusting screw 104 sets the gap between armature end 98a and polepiece 94a, and a spring 102 biases the armature about its pivot 99 against the core 86. The tip bar 70 has secured to it the latching part 77, which is bimetallic to provide ambient temperature compensation, and bar 70 carries an adjustment screw 84 which is engaged by bimetal 24 when it deflects to operate the trip bar. An insulating barrier 108 separates core 86 from the current-carrying flexible braid 22. The operating mechanism, the releasable cradle 46, the latch 61 and the trip bar 70 are carried by a common metal frame 44, as claimed in Specification 1,053,655.

Abstract: 1,251,482. Colour television. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 20 March, 1970 [25 March, 1969], No. 13481/70. Heading H4F. [Also in Division G2] A colour separating prism system comprises a plurality of dichroic layers 44, 46, each on a prism surface, each layer being reflective for a different part of the optical spectrum, and at least one partially reflective, partially transmissive layer, on a further prism surface, disposed in an air gap 45 adjoining a dichroic layer. The blue component of incident light 57 is reflected by the dichroic layer 44 on a prism 41, and after total internal reflection at face 48 of the prism impinges on a 'blue' camera tube 54. Red and green light passes through the layer 44, crosses an air gap 45 and strikes a partially reflective partially transmissive layer on face 49 of a second prism 42, and that part which is reflected also reaches the " blue " tube 54, so that if the incident light 57 is white the light received by the tube 54 is white-blue. Light passing through the layer on face 49 strikes the second dichroic layer 46 on the prism 42, where the red component is reflected and reaches a " red " tube 55 after further reflection at face 49. The green component crosses an air gap 47 where some is reflected at a second partially reflective partially transmissive layer on face 50 of a third prism 43 and reaches the " red " tube, while most passes directly through the prism 43 to a " green " tube 56. The layers on the faces 49 and 50 may comprise small reflecting domains, and their reflection coefficients may or may not be frequency-dependent. Each partially reflective layer gives rise to a second image at the corresponding camera tube, and the air gap must be so narrow that the system is incapable of resolving the two images.
