Abstract: 1,196,880. Cantilever concrete structures. P. FRANCO. 13 Nov., 1968 [14 Nov., 1967], No. 53896/68. Heading E1W. A building structure having a cantilever portion is constructed using a reinforced concrete slab comprising a main portion 1 adapted to be supported at opposite ends, and spaced from one end at least thereof, a cantilever slab portion 4 connected thereto by trussed metal reinforcing elements which are additionally stiffened in the space between the slab portions. The trussed metal reinforcing elements described comprise a pair of triangular sectioned lattice members each having a single longitudinal upper member connected by struts 7 to a pair of longitudinal lower members embedded in the slab portions 1 and 4, the additional stiffening being provided by struts 8 connecting the lower members in the space between the slab portions I and 4.

Title: Rotary mechanical translating device
IPC: F16H37/06
Filed: 1971-11-22
Abstract: 1338035 Rotary mechanical relays TAWK WATSON 22 Nov 1971 [3 Dec 1970] 54036/71 Heading F2X A rotary mechanical translating device comprises a first and second differential each having a first, second and third connection, a selflocking rotary coupler having an output connection connected to the first connection of the first differential, the self-locking rotary coupler having an input connection connected to the first connection of the second differential, and a prime mover means for driving the second connections of both differentials. In one embodiment, Fig. 1, the spider gear 2 of a first differential 1 and the spider gear 11 of a second differential 10 are meshed and driven through a gear 16 and shaft 17 by an external prime mover. One of the end gears of differential 1 is connected to the output shaft 3 and into other end gear to a shaft 4 connected via a first worm gear 5 and worm 6 to a bevel gear 7. This meshes with a bevel gear 8 connected via a shaft 9 to one of the end gears of differential 10, the other end gear of which is connected via a shaft 12 to a second worm gear 13 and worm 14, connected in turn to the input shaft 15. The ratio and direction of the two drives to the differential 1 is such that a balance occurs, resulting in zero rotation of output shaft 3, when the input shaft 15 is held stationary, rotation of this shaft resulting in an unbalance with consequent rotation of the output shaft 3. This device produces amplified unidirectional rotation at the output and may be operated in the reverse direction by reversing the direction of the prime mover. In order to produce amplified bidirectional rotation at the output, a third differential's first end gear is attached to the second worm and worm gear (Fig. 5, not shown), and its spider gear is also driven by the prime mover. The drive ratios are selected such that the second differential is overdriven by the prime mover, and the third differential drives the second differential so as to cancel its overdrive. A third worm gear is attached to the second end gear of the third differential and co-operates with a third worm which acts as the input and may be driven in either direction, producing rotation in the output in corresponding directions. The system gain, however, is greater in the direction in which the third differential drives the third worm gear. When the third worm drives against the third worm gear, more effort is required. Amplification, however, occurs in both directions. In a balanced device (Fig. 6, not shown) in which the input drives the output with equal effort in both directions and which is constructed from four differentials and four worms and worm gears, the output differential derives its power from two other differentials driven from a prime mover. A fourth differential controls the system balance and is attached to the input connection.

The main mixture is relatively lean whilst the auxiliary mixture is relatively rich. A pressure receiving chamber 19 for the auxiliary mixture is formed with a multiplicity of small passages 22 Fig.2 (not shown) and has a volume greater than the combustion chamber 2. The compression pressure acts in chamber 19 to force the auxiliary mixture into the auxiliary combustion chamber 2' as poppet valve 9' opens. On the closure of the valve 9', the auxiliary mixture is ignited by a spark-plug 16 and the resultant flame ignites the main fuel mixture in the main combustion chamber. A checkvalve 18 is provided to prevent the auxiliary fuel mixture from being pushed out of the auxiliary combustion chamber whenever the valve 9' is open and a back pressure from exhaust gases is generated in the exhaust passage 10.

The solvent used can be (a) an anthracene oil which can have been obtained from a tar distillation fraction having a 5-95% boiling range between 280‹ and 350‹ C. by adding 10-20% of a lighter fraction of the tar and removing an anthracene-rich paste by centrifuging or filtering; or (b) a polycyclic aromatic solvent obtained by catalytic or thermal cracking of petroleum and which suitably, apart from a non-distilled portion of at least 5%, distills at a temperature between 500‹ and 50‹ C. below the maximum temperature in the extraction stage at a pressure of at least 0À75 atmos. The extraction can be carried out at 400‹ C. and the concentrated extract can be coked to a final temperature of 500‹ C. and the coke produced calcined at 1300‹ C. The pretreatment of the solvent reduces the amount of solvent-derived coke which contaminates the product coke.
