Title: Light tapping device for multimode optical fibres - involves connecting fibre to section with alternating curves thus inducing mode transpositions
Inventor: JEUNHOMME LUC
IPC: G02B6/42
Filed: 1975-12-05
Abstract: The by-pass or tapping device for multimode optical fibres, comprising a core surrounded by a material of lower refractive index. The fibres whose light (6) is to be tapped is connected to a section of optical fibre having alternating curves which induce a succession of mode transportation in the light propagating in the core of the fibres. There are sufficient mode changes to ensure that the final value of the propagation constant is below the lower limit for propagation in the core. Thus the light whose propagation contact has been reduced, propagates in the surrounding material.

Title: Vehicle platform mounted at quayside - has ram orientation limited by cable and push rod moved outwards by rotary knee-joint
Inventor: TOPOLAY MICHAEL A J
IPC: B65G69/28
Filed: 1975-12-19
Abstract: The platform (5) is pivoted to a frame set into the quayside. When the platform is to be raised the hydraulic ram (10) is operated. As theram extends its orientation is limited by the cable (26) and it moves the push rod (14) outwards by forcing the knee connecting pieces (20) to rotate anti-clockwise about the pivot (22a) until their sides are flush with the underside of the platform. As the push rod moves outwards the flap (7) is raised about its hinge (8) until it is level with the platform and this is placed over the rear of a lorry. The platform has an electrical switching mechanism (30) which lowers it automatically and an hydraulic fail-safe mechanism (11a) to ensure that it cannot collapse suddenly.

Title: Crane bridge for heavy loads, suitable for foundries - has high tilt resistance, and flexes to compensate for crane rail distortion
IPC: B66C17/00
Filed: 1976-04-06
Abstract: Crane bridge, esp. for heavy loads, such as foundry cranes, using two main bridge carriers connected by traverses; each carrier is located on one end (I) on a crane rail by a main balancer, whereas the other end (II) is located on the second crane rail by two auxiliary balancers to achieve three point mountings; and each carrier is fitted with a crab rail. The novelty is that the main balancer mountings are displaced by a dimension (a) outside the crab rails and in the direction of the crane buffers to prevent tilting, and ends (I) are joined by a wide traverse providing horizontal stiffness but some vertical flexure, whereas ends (II) are joined by a strap on pivot mountings. The crane bridge is extremely stable with high resistance to tilting, but some flexure is provided so the bridge will always sit securely on the rail track even if the rails are somewhat distorted.

Title: Crane tower assembly system - has single lever sliding upper section into line with lower one
IPC: B66C23/28
Filed: 1976-06-24
