Title: Improvements in or relating to ground-marking machines
IPC: E01C23/24
Filed: 1937-03-13
Abstract: 488,310. Line-markers for roads &c. TILKE, G. F., and BIGGLESTON, H. March 13, 1937, No. 7451. Addition to 445,953. [Class 132 (ii)] The ground - marking machine claimed in the parent Specification is modified by carrying the brush (or brushes) at the lower end of a spindle that is journalled in a substantially vertical bearing and is movable bodily up and down, and in providing manual operating means connected to the upper end of the spindle for rotating the brush (or brushes) in order to give a sharply defined edge to the end of the line. The machine is propelled by a laterally-situated handle 19 and is supported on two large wheels 10, and a smaller swivelling wheel 14 mounted directly behind one of the larger wheels or nearly so. The swivelling axle of the smaller wheel may be locked by a removable plate 110. The brush 54 is rockably carried on the spindle 50 journalled in the vertical bearing 30, and the vertical bearing is carried by parallel links 40, 42. A universal joint 60 connects the top of the spindle to an operating rod 62 which may be rotated to rotate the brush by means of a crank handle 70. The crank handle is feathered to the operating rod and in its lower position a tongue on the handle enters a slot in a fixed member to retain the brush in its line-marking position. When the crank handle is slid upwards against a stop on the operating rod, the rod may be drawn upwards to raise the brush from the ground. If the machine is then to be travelled idly over the ground a lever 90 is operated to slide a catch tray 88 under the lifted brush, the tray at the same time pushing a wind shield 98 (enclosing the paint &c. distributer) into a raised inoperative position. The distributer, which is of tubular perforated form, is controlled by a handle 82 and receives the paint from a tank 76. The machine may be connected as a trailer to the back of a bicycle by a drawbar secured by a readily detachable connection to a bracket 124. A washing tank 128 may be carried by the machine.

Title: Process and apparatus for the conversion of heavy hydrocarbon oils into lighter oils
IPC: C10G15/00
Filed: 1927-03-21
Abstract: 275,120. Northrup, V. W. March 21. 1927. Mineral oils. - In a process for converting heavier hydrocarbon oils into lighter hydrocarbon oils, a mixture of the vapours of the heavier hydrocarbons and gas having available hydrogen is passed through an electrified zone and thereafter through a catalyzing zone independent of the electrifying zone. Heavier hydrocarbon vapours from a vaporizer A are passed up a tube B to which hydrogen, methane, natural gas, &c. is admitted at C<1>. An insulated wire D is suspended within the tube B and a source of high tension alternating current is connected between the wire D and the tube, the potential difference being from 2000 to 8000 volts according to the type of heavy petroleum employed. From the tube B, the electrified mixture passes to a catalyzing chamber comprising converters consisting of lagged and heated tubes I in which are supported corrugated tubes J; the tubes I, J are composed of, or coated with catalytic material, for example, nickel, cobalt, palladium, aluminium, iron, or mixtures thereof, for example, nickel containing 5 per cent of iron and 5 per cent aluminium. The temperature of the catalyzing chamber depends upon the type of heavy petroleum used and may be from about 725‹ to about 1000‹ F., the temperature of the various converters within the catalyzing chamber being successively slightly higher. From the catalyzing chamber, the mixture passes to a dephlegmating tower M, and thence to a cooler O maintained at about 200‹ F. to 400‹ F., whereby heavier vapours are condensed, the light product passing in vapour form to a condenser Q<1>.

[Class 103 (i)] In a brake in which the support which takes the braking torque is disposed substantially in the medial plane of the shoes and has a radial guide arm for each brake shoe, springs which disengage the shoes from the drum are so arranged as also to urge the shoes against the guide arms. Shoe adjustment means are described. As shown, the support 12 is in the form of a plate with a central aperture and shoe guide arms 20 and is fixed to the axle housing of a vehicle by bolts 14. The shoe ends are engaged by the pistons 39, 40, of hydraulic cylinders 36 which each have flange 38 by which it is bolted to the support 12. Release springs 66 extend between adjacent ends of the lining-carrying flanges 26 of the shoes and are attached to them at points 68, Fig. 2, that are laterally offset from the webs 28 of the shoes which are of T-section so that the springs act also to urge the webs against the arms 20. The springs may instead each be attached at one end to a projection 80, Fig. 5, on the guide arm 12a, the other end 82 being extended through the shoe web 28 and engaging a hole in the flange 26. The spring is deflected by a boss 88 so that it has a force component which acts to hold the web against the arm 12a. One piston 39 of each pair engages the adjacent shoe end through a screwed rod 52, the shoe can be adjusted for wear by turning the piston by a toothed disc 60 secured to the piston, turning of the rod 52 being prevented by the shoe, the web of which engages a slot in the rod. The piston is held against rotation by engagement with the disc 60 of the downwardly-bent part 94 of a resilient plate 91 fixed to the head of the rod 52 and which serves also as a hardened bearing plate for the shoe end. The end of the piston 40 also is slotted and carries a bearing plate 44 for the shoe end. The shoes anchor at one end or the other according to the direction of rotation of the drum, the anchored end of each shoe bearing through the piston on a flange 76 within the cylinder.
