Abstract: 1,155,844. Moulding tiles. TERCOL Ltd. 21 Oct., 1966 [17 Aug., 1965], No. 35134/65. Heading B5A. [Also in Divisions C3 and E1] In a sheet or tile casting process the resin, e.g. a polyester, polyurethane or an epoxy, contains particles having a density lower than that of the resin matrix so that they move to the surface during setting. The movement of the particles can be assisted by externally applied force, e.g. a magnetic or electrostatic force. The particles may be selected to impart a decorative effect to the surface or to impart a particular property, e.g. slip resistance. The particles may be composite, e.g. by being produced by mixing hollow spheres of phenolic resin and silicon carbide, silica or aluminium oxide or by being embedded in a foam. The particles may be of a polyester or epoxy resin. When used as flooring the glass may be removed by scrubbing or grinding.

IPC: G02B21/36
Filed: 1959-10-20
Abstract: 904,280. Lens mountings; microscopes. COOKE, TROUGHTON & SIMMS Ltd. Oct. 13, 1960 [Oct. 20, 1959], No. 35512/59. Class 97 (1). An optical lens assembly mounting includes a first cantilever arm carried by a shaft supported in the mounting, at least one lens element arranged at the free arm end with the optical axis thereof parallel to the shaft axis, means for pivoting the arm about the shaft axis to displace the element into and out of a required optical path, and further means for displacing the arm axially of the shaft so as to displace the element along its optical axis. The invention is described as applied to a projection microscope and as shown, the mounting incorporates a corrector lens assembly 1 and a projection eyepiece assembly 2, which can be selectively interposed in the light path. The mount 6 of the lens assembly 1 is carried by a cantilever arm 7 which is fast on an arm 8 parallel to the optical axis and journalled in a mounting 5. The lens assembly 2 includes a central lens 12 carried by an arm 11 attached to a cylindrical rack 9, which is freely rotatable around and slidable on the shaft 8, the lens 12 being disposed between lenses 15, 16 in a mount 14 which is carried by an arm 13 fast with the shaft 8. Relative angular movement of the arms 10, 13 is prevented by grub screws which pass through the arm 10 and maintain contact with the arm 13. Pivoted to the arm 7 is a yoke 19 to which is attached an auxiliary slidable push rod 20, movement of which brings either or none of the lens assemblies 1, 2 in the light path. Focusing movement of the central lens 12 of the projection lens assembly 2 is effected by rotation of a pinion 27 which engages the cylindrical rack 9. This pinion 27 is mounted on a shaft 28 attached to a drum 30 between which and a central drum 36 is a friction ring 39 acting as a slipping clutch. There is also provided a fixed drum 31 and a drum 33 which is rotatable into any one of three positions corresponding to the magnification set in a magnification chamber within the microscope. In operation, the magnification of the microscope objective, as read on the end portion 38 of the drum 36, is set against an index on the drum 30, the index on drum 33 is then set against the appropriate magnification changer value on the fixed drum 31, drums 30, 36 are rotated together to form lens 12, whereupon the final image magnification can be read from the end portion 37 of the drum 36 as it appears against another index on the drum 33.

The bearing member 12 supports an axially displaceable pivot pin 13, Fig. 3, which connects the frame to the respective leg 8. The lever 31 has a displaceable abutment member 35 having an arm 38 engageable with the pivot pin 13 to effect axial displacement thereof and having an arm 40, Fig. 4, which facilitates the rotation of the member 35 about a pin 36 and against the action of a spring 43, so as to move the arm 38 out of engagement with the pivot pin 13 and thus allow the lever 31 to rest inoperatively against the respective leg. The pin 13 is screw-threaded at 14, Fig. 3, and has a bush 18 screwed thereon. A spring 20 is positioned between a flange 19 of the bush 18 and a flange 17 of the head member 15. The lever 31 is pivotally connected to the member 15 by means of a pin 33 and a spring 34 is located between a portion 32 of the lever 31 and the member 15. In use, when the arm 38 of the member 35 is in line with the pin 13 as shown in Fig. 4 and the lever 31 is moved into alignment with the leg as shown in Fig. 2, the teeth of the rings 21, 22 disengage and allow the leg to be moved into a different angular position. The lever 31 is then released, the spring 20 moves the lever to the position shown in Fig. 3 and the teeth of the rings 21, 22 re-engage. The member 35 is rotated by means of the arm 40 thereof so as to disengage the arm 38 from the pin 13 and allow the lever 31 to be moved by means of the spring 34 into the position shown in Fig. 2. One leg 8 is connected to an angle member 2, Fig. 1, and two legs 8 are each connected to the member 2 via a tube 4. A weapon carrier 5 is supported by means of a fork 6 which is rotatably mounted on the member 2 and by means of an adjuster device 7 which is displaceably supported for vertical and lateral adjustment on an aiming guide 3 carried by the tubes 4.
