Title: Improvements in grabs
IPC: B66C3/06
Filed: 1920-09-27
Abstract: 172,761. Smith, W. Sept. 27, 1920. Grab-buckets. -Comprises means for manipulating gravity locking- catches in grabs of the kind in which a lower fall block moves hetween the head of the grab and the bucket hinge during the operations of opening and closing. In the illustrated form applied to a singlechain grab, the operating rope p is wound round an upper block a4 fixed on the framework of the g r a b and also round pulleys on shafts e' carried by the lower fall-block which slides on telescopic frame members f, and is guided by rollers e<3> during its sliding movement. When the open grab rests on the ground at the loading station, further paying out of the rope lowers the fall-block on the guides. The fallblock carries two swinging gravity catches g, linked by interengaging teeth to act in unison, and forced inwards towards each other by weighted levers m so that they pass freely into a casing associated with the bucket pivots, during the descent. At the lower limit of the movement the levers m are raised by stops n on the buckets to free the catches g and allow them to swing outwards by gravity into engagement with notches in the casing. Hauling on the rope then raises the fall-block and the bucket pivots to close the grab, and eventually hoists it after the fall-block has reached its upper limit. The levers mare released from the stops during this process, but the weight of the load prevents the catches from being disengaged. The raised grab is swung over and lowered on to the dump heap. Slackening of the rope then lowers the catches relatively to the notches in the casing and. allows the levers m to disengage them. Hauling on the rope then first raises the fall-block and finally raises the whole framing, leaving the unsupported bucket pivots free to fall and open the grab. The opened grab is then lowered on to the loading heap for a. fresh operation. The grab may be made into a doublechain grab by adding a supporting chain to take the weight of the load when desired. This enables the grab to be opened when suspended. In a modified form the catches g act inwardly instead of outwardly and engage a collar on a central bolt instead of a casing.

Title: Improvements in or relating to the catalytic hydrogenation of gas oils
Inventor: THIERRY GHISLAIN MARC DE MENTE
IPC: F02B3/06
Filed: 1958-08-27
Abstract: A process for the reduction of the pour point of a petroleum gas oil distillate by catalytic hydrogenation comprises hydrogenating the distillate (which has a pour point higher than 0 DEG  F. and a viscosity lower than 10 centistokes at 100 DEG  F.) in the presence of a catalyst comprising oxides of metals of Group VI and VIII supported on a mixed silica-alumina base (the silica content of the catalyst being less than 40% of the total weight of the catalyst) at a temperature from 400 DEG  to 450 DEG C. (but below the temperature at which substantial cracking of the distillate occurs) and at a pressure from 5 to 100 kg./cm2 (but above the equilibrium pressure at which the amount of hydrogen evolved in the reaction is equal to the amount of hydrogen consumed), with a hydrogen recycling rate of at most 15 mols. of hydrogen per average mol. of charge and a charge delivery rate of 0,5 to 10 v./v./hr.  The catalyst preferably comprises oxides of cobalt and molybdenum supported on silica-alumina.  The product of the process comprises mainly a fraction whose initial boiling point is identical with that of the starting material but which has, with respect to the latter, a lower pour point as well as a reduced sulphur content and a higher Diesel Index.  The total reaction product may be separated by distillation into various fractions, for example (1) a gas oil fraction the cut point of which is set so that the fraction conforms to gas oil specifications, particularly as regards the flash point and pour point, and (2) a petrol fraction which can either be used as such or preferably as a charge to a reforming process.  Specification 749,850 is referred to.

A fail-safe circuit for energizing a relay 8 when an input voltage 19 is within predetermined limits comprises a pair of emittercoupled transistors 1, 2 comparing the input voltage with a reference level set by resistors 11 and (12 and 13) and a further pair of similar transistors 3, 4 comparing half the input voltage with a reference level set by (11 and 12) and 13. If the input is below the lower limit transistors 1 and 3 are cut off and 2 and 4 conduct, so that the relay is not energized. When the input rises above the lower limit transistor 1 conducts, onergizing the relay and cutting off 2. Above the upper limit transistor 3 conducts cutting off 4 and hence 1 to de-energize the relay; resistor 10 is chosen to make transistor 3 bottom to reduce the current drain. The input impedance and sensitivity can be increased by including an NPN transistor as current-amplifier between transistor 1 and the relay (Fig. 2, not shown). This transistor may have a Zener diode in its emitter lead (Fig. 3, not shown) to provide against false operation due to leakage collector current in transistor 1. When using such a current-amplifier resistor 10 may be omitted.
