Patent GB-2044716-A (GB)
Title: Pulley Hoist
IPC: B66D3/04
Filed: 1979-03-20
Abstract: The invention comprises a simple, manually operated hoist mechanism embodying inherent automatic variation of mechanical advantage. In this invention, the rope is passed around two pulleys, these being so controlled by friction ratchets that only one is free to rotate at any one time. Beyond the pulleys, the rope at one side is in communication with the load and with a tension spring, the rope on the opposite side being in communication with the load only. Repeated bowing and release of that length of rope lying between the pulleys first raises the load and extends the spring, then, as the ratchets reverse their functions, locks the load and allows the spring to restore the rope to its original line. Lowering is by controlled release of the ratchets. <IMAGE>

Patent GB-2092163-A (GB)
Title: Selective Polymerization of Butadiene from C4 Fractions
IPC: C08F240/00
Filed: 1981-02-03
Abstract: The invention relates to a process for selective polymerization of 1,3- butadiene by using C4-fractions which occur in the pyrolysis of petroleum, by initiating the reaction with soluble lithium initiators of the type (a) dialkali metal diamines, (b) dilithium diamides, (c) dilithium addition compounds of conjugated dienes, (d) polylithium oligodienes, (e) dilithium butane and (f) dilithium diphenol ethers. The polymerization of the butadiene is performed in the mixture without prior separation of the other components in the C4-fraction (butene-1, cis- and trans-butene-2, n- and i-butane, i-butene) and without their incorporation into the polymerizate. It has been found that butadiene can be selectively converted into polybutadienes and, if suitable anionically polymerizable monomers are added, into copolymers. The molar masses can be adjusted to suit particular applications. By the addition of suitable electrophilic end forming agents, polymer products which are functional in their end state can be obtained.

Title: Control Means for a Continuously Variable Ratio Vehicle Transmission
IPC: F16H61/662
Filed: 1981-05-27
Abstract: The control means comprises a three dimensional control map 11 and a probe (not shown) which moves over and is spring pressed towards the surface of the map. Movement of the probe is controlled in two dimensions to fix road speed and accelerator pedal coordinates, the third dimension perpendicular to the plane of the figure, representing the required ratio of the continuously variable ratio transmission. The probe is carried by a bracket by which it is moved in the X direction in response to accelerator pedal movement and is mounted for sliding movement in the bracket in the Y direction so that, when it is away from the idling region 19 of the map, it tends to move in the Y direction downhill towards a valley 15 bounded by a contour 14 thereby establishing high ratio. Such movement in the Y direction is limited by a stop blade or blades positioned by road speed responsive means. <IMAGE>
