Filed: 1929-09-05
Abstract: 339,317. Uhde, F. Oct. 3, 1928. [Convention date]. Grant of Patent opposed. Hydrogenation, destructive. - Carbonaceous materials, e.g. oils', bitumens, carbon, wood, &c. are transformed into valuable hydrocarbons of low boiling point by heating them with finely divided or spongy iron and water in an autoclave to above 400‹ C., the proportion of water present being such that a pressure of 200 atmospheres is developed during the reaction, the water reacting with the iron to form hydrogen. 3 parts lignite tar, two parts of spongy iron, and one part of water are mixed and fed into an autoclave where they are heated to 400-500‹ C. with continuous agitation, a pressure of 200 atmospheres resulting. The products are separated from the water and distilled and a product containing 60- 80 per cent of hydrocarbons boiling below 200‹ C. is obtained. The residue can be used as a fuel oil or re-introduced into the process. The gases obtained can be used to regenerate the iron oxide. Four parts of wood flour, 2 parts of spongy iron and 3 parts water and ¢part soda similarly treated give about 20 per cent oils and a watery layer containing methanol, acetone, aldehyde, and acids. Hydrogenating catalysts, e.g. nickel, copper, zinc oxides, zinc chromate or splitting catalysts, e.g. aluminium chloride, may be added, and also water vapour reducing agents, e.g. soda, potash, &c.

Abstract: 152,531. Bauers, A. K. J. Nov. 5, 1919. Locks, permutation. - A locking- mechanism for stationary locks, cycle locks, or padlocks comprises a bolt member controlled by a series of tumblers which are mounted in a casing through which they extend and constitute a keyboard for selection. As shown, two sets of tumblers 12 are mounted on pins 2 of a casing 8 and are slotted to embrace and control the movement of pins 11 on a member or bolt 10, which is normally retracted by a a spring 17 and has a pin 13 extending through a slot in the casing and carrying an operating knob. The tumbler slots 20, some of which are straight and others inclined, terminate in enlargements providing flat or corrugated obstructing edges to the pins 11 except when the tumblers are rocked on their pivot by manipulation of heads on their outer ends to aline the slots with the pins. When so alined, the member 10 is moved by the spring 17 to unlocking position and owing to the shape of the slots the tumblers are alined. When the member 10 is moved by the operating knob into locking position, against the action of the spring 17, the pins 11 are carried against inclines at the bottom of the enlargemert of the slots and thereby aline the tumblers, the obstructing edges 21 of which are thus carried opposite the pins 11. In the application shown, the movement of the member 10 acts through toggle links 15 to operate pivoted locking claws 16.

Title: Apparatus for transporting and emplacing stone and other structural material in the building of breakwaters and moles
IPC: E02B3/06
Filed: 1935-10-07
Abstract: 465,944. Transporters for building breakwaters &c. JOYCE, A. A. Oct. 7, 1935, No. 27646. Convention date, Oct. 15, 1934. [Class 78 (iv)] Comprises a combination of parts forming a travelling crane or transporter especially adapted for building breakwaters and the like and for use under other conditions which involve the use of an uneven and unsound road bed, the chief constructional features comprising a three point support for the crane, a light slueable boom with travelling load trolley guyed to a light mast which in turn is guyed rearwardly and balanced by weights attached to lateral outriggers, and the construction of the three-point support to provide room for a clear run-through for rail vehicles bringing materials to be handled by the load trolley and in some cases also with a suspended overhead track along which the trolley may run off the boom to pick up loads from the rear of the apparatus. In the illustrated form the three-point support is formed by four bogie trucks 91 running on two parallel rail tracks. Each of the forward bogies carries a pivoted leg 73 connected at the top by a crossgirder 27 while the rear pair each carry a standard, cross-connected by the girder 71. The main supporting girder 70 is connected flexibly to the centre of the girders 27, 70. The front and rear bogies are tied by members 93. The boom 42, carrying the travelling load trolley 44 and driver's cab 85, is guyed to the top of a light mast 45 by ropes 46, the mast being guyed rearwardly by the tackle 48 and laterally by ropes 49 passing to out-riggers 50 kept in position by weights 87 or by a suitable anchorage. The underside of the girder 70 may carry the rails for a suspended track in alignment with the track on the boom when the latter is in its central position, thus allowing the trolley 44 to pass from the boom to the rear of the appliance. In addition the lateral spacing of the supports on the bogies provides space for a central track along which vehicles may pass through the crane. This latter track may be picked up by the crane and transported with it as the appliance is moved forward to take up a new position as the work proceeds. The Specification as open to inspection under Sect. 91 also included a construction in which the light mast was replaced by a heavier braced tower structure, while the girder 70 was also braced and substantially heavier in construction. This subject-matter does not appear in the Specification as accepted.
