Abstract: 1436413 Planetarium C A CROSS 31 July 1974 [2 Aug 1973] 36859/73 Heading G2J A celestial body image projection system for a planetarium has a projection lens 6 and, as an image source, either an internally illuminated sphere 1 comprising a translucent hemisphere and an opaque hemisphere or a translucent sphere 30 of which one half only is internally illuminated at any given time. In its simplest form shown in Fig. 1, half the sphere 1 is blacked out with paint and the other half has markings 8 simulating detail on the celestial body. The sphere 1 is rotatable by a motor about an axis 4. In Fig. 3 a lamp 32 is carried by a partition 31 so that only half the sphere 30 is illuminated. The sphere is rotatable about an axis 34, the partition 31 is carried by a shelf 33 rotatable about an axis 35, and the partition 31 itself is rotatable about a horizontal axis by gears 37. This enables a demonstration to be given of what a planet looks like to an observer in a circular equatorial orbit over a whole year. The projection may be used in conjunction with star field and solar projectors having occulting discs to prevent image overlap. Similarly if the projector projects the body of Saturn, a second projector may project the rings. A zoom lens may be used.

Abstract: 1474348 Fibrous laminates KENDALL CO 8 Sept 1975 [17 Sept 1974] 36906/75 Heading B5N [Also in Division D1] A plaid effect laminate fabric, Fig. 5, is produced by cross-laying two layers of a staple fibre non-woven fabric comprising areas 12, Fig. 1, of relatively low fibre density having a finger-like configuration with a majority of the fibres therein orientated in a direction substantially normal to the fingers, and immediately adjoining areas 11, 44 of relatively high fibre density in which a majority of fibres are orientated in a direction substantially parallel to the fingers. The fabric is formed by air laying drafted staple fibres on to a moving air permeable conveyer screen 22 having impervious finger-like resist areas disposed on or over the screen, by suction applied at 29. In Fig. 2 fixed finger-like striping bars 23 are disposed across the width of the screen with the distance between the edges of the bars less than the fibre length, preferably less than half the average fibre length. If the bars are close together the fabric has a ribbed profile. Alternatively the bars are arranged perpendicular to the machine direction. The bars may not cover the whole width of the screen to produce a fabric having a zone of random fibre orientation. The resist area bars may be replaced by impervious areas formed on the screen by placing strips of tape on the screen or by blocking openings in the screen by paint or plastics, as in the formation of the fabric of Fig. 6. Above a certain weight of fibres deposited per unit area the fabric has a top layer of randomly orientated fibres. Bonding.-In the examples the fibres are a mixture of rayon fibres and vinyl acetate/vinyl chloride copolymer fibres. The fabric is autogeneously bonded by heater 25.

Heading B8C: Stacks of profiled rolled steel products, e.g. angles and channels are formed by inverting one layer of the products over a second layer so that the two layers .are interfitted and depositing the double layer on a stacking table. The products are fed longitudinally along a conveyer 1 to a conveyer 2 and then to a faster moving inclined conveyer 3. A counting device 4 above this conveyer counts the products and causes their feed from the conveyer 2 to be interrupted intermittently so that counted, spaced groups are fed on to a more slowly moving conveyer 5. The groups are then fed by a conveyer' 6 over two magnetic inverter devices 7, 9. A reciprocating stop 8 allows the first group 16 to pass to the inverter 9 and holds back the second group 15 on the inverter 7, which is then rotated to deposit its group 15 on to the group 16, the inverter 9 being subsequently rotated to deposit the double layer on to a stack 10 on a table 11. The table 11 is gradually lowered until it deposits its load on to a conveyer 12, which carries the stack 10 through a bundling machine 13 and weighing machine 14 (not detailed). In order that the lowest and every alternate layer 15 has an odd number of products, while the second and every, alternate layer 16 has an even number, the counting device 4 automatically increases and decreases the number in each group by one.
