Abstract: L’invention concerne notamment un composant optique de sécurité (201) comprenant une première couche (213), au moins une première structure diffractive (S) gravée sur ladite première couche, une deuxième couche (214) réflective recouvrant au moins en partie ladite première structure diffractive. Ladite première structure diffractive comprend un premier motif (M1) constitué d’un ensemble de facettes agencées pour former une pluralité de sous-ensembles de facettes, chaque sous-ensemble de facettes comprenant une ou plusieurs facettes à symétrie de révolution agencées de façon concentrique. Dans chaque groupe d’une pluralité de groupes de sous-ensemble de facettes, lesdits sous-ensembles de facettes présentent en des régions ponctuelles définies par des coordonnes angulaires identiques, une altération locale de la surface, de telle sorte à produire un objet graphique reconnaissable pour un angle de tilt et un angle d’azimut donnés. Les coordonnées angulaires varient d’un groupe à l’autre, de telle sorte à produire un effet visuel dynamique observable en réflexion par changement de tilt et/ou d’azimut.  FIG. 2A

Abstract: 1395916 Fork-lift trucks LANSING BAGNALL Ltd 27 April 1973 [8 May 1972] 21444/72 Heading B8H [Also in Division F2] An industrial lift truck for use in narrow aisles between goods racks comprises a load lifting carriage 12 which moves vertically along a mast 11, a turret head 13 mounted on the carriage 12 for sideways movement relative thereto and a load supporting structure 14 consisting of forks which are mounted on the turret head 13 for rotation relative thereto about a vertical axis. As is shown in Fig. 2, the turret head 13 is movable from a first position shown in full lines, where it is flush with one edge of the carriage 12, to a second position shown in phantom lines where part of the turret head 13 projects beyond the other edge of the carriage 12 to permit the forks to enter a rack 15, but if the forks were pointing in the opposite direction the turret head 13 would be able to project beyond the other edge of the carriage 12. This effect is achieved by means of a pair of stop members 42, 43, Figs. 5, 6, which are mounted on the turret head 13 and are engageable with a fixed abutment 44 located at each end of the carriage 12 and one connected to a bell crank lever 41 which is rotatable about a vertical axis 41a on rotation of the load supporting structure 14, such that when the structure 14 is rotated to face towards one of the sides of the truck the stop member nearer that side is withdrawn to a position in which it cannot engage with an abutment 44 whereas the other stop member is moved into its operative position in which it can engage with both of the abutments 44. Fig. 5 represents the arrangement of the turret head 13 and carriage 12 shown in phantom lines in Fig. 2 while Fig. 6 represents the arrangement shown in full lines. Sideways movement of the turret head 13 relative to the carriage 12 is effected by means of an electric motor (37), Fig. 3 (not shown), which drives a pair of gears (31) and thus gears (30) mounted on shafts located on the turret head 13, Fig. 4 (not shown), the gears (30, 31) and further gears (34) which mesh with the gears (30) being in engagement with respective racks (32, 33, 36) located on the carriage 12. Rotation of the load supporting structure 14 is by means of an electric motor (50), Fig. 3 (not shown), which drives a vertical shaft (47) on which the structure 14 is mounted.

Abstract: 1480983 Photo-copying apparatus G RITZERFELD 25 Sept 1975 [11 Feb 1975] 39271/75 Heading G2A  A photo-copying apparatus has a first imagebearing original, and a second image-bearing original partially masking the first, and a further masking means for the first original, the two originals being relatively displaceable so as to vary the gap between the two masking portions through which the visible portion of the first original is copied. The arrangement is similar to that disclosed in Specification 1481148 but in the present case a second original acts as one of the masking means. The two originals are supported on a glass plate 1, heading original 25 below and partly masking the line original 26. These are each held by a clamping device, so that either can be moved to the left or right with respect to the other. Thus any lines on the line original can be brought alongside the heading original. A transparent strip 28 carrying a number of opaque masks such as at 31 can be wound across between reels 29 and 30, and this may be manually controlled so as to bring any of the masks into any position. The transparent strip 28 itself may carry material which is also projected and copied.
