[Classes 20 (iv) and 87 (i)] Walls are formed of connected wooden blocks of three different types, the blocks a of one type having a vertical groove 2 at each end, the blocks b of the second type having a vertical groove 4 at one end and a horizontal tongue 5 at the other end, and the blocks c of the third type having a vertical groove 7 at one end and a horizontal slot 8 at the other end. The blocks are assembled so that the tongues 5 of the blocks b engage the slots 8 of the blocks c to form a corner construction, and feathers d engage the co-operating vertical grooves 2 in the end faces of the blocks. The blocks of the second and third pairs are formed in two different lengths as shown at b, b<1>, c, c<1> in order to form a corner construction bonding with the blocks a. The blocks a may also be shorter than those shown in the drawing, where necessary. Rods g are inserted in aligned holes provided in the co-operating parts of the blocks b, c. Rods f are also inserted in holes 3 provided in the blocks. The length of each block is a multiple of its width, and each block has a convex top surface and a concave bottom surface. The blocks are built up on a concrete brick, or like foundation h having a layer i of tar, tarred pasteboard or the like thereon, and the concave bottom surface of the lowest course of blocks is filled with concrete or cement k.

Title: Dehydrogenation process
Inventor: BAJARS LAIMONIS
IPC: C07C5/56
Filed: 1961-06-23
Abstract: Diolefins are obtained by dehydrogenating a C4-C6 mono-olefin in the vapour phase at 400-850 DEG  C. with at least 1/4 mol of oxygen per mol of olefin and an amount of an iodine-liberating material sufficient to provide more than 0.001 mol of iodine per mol of olefin, the partial pressure of olefin being less than half the total pressure at pressures of above one atmosphere and less than one half an atmosphere at pressures up to one atmosphere, and in the presence of a metal other than silver, gold, proactinium or a transuranic element or an oxide, hydroxide or salt thereof.  Preferred olefins are butenes and methylbutenes which yield butadiene and isoprene. The molar ratio of oxygen to olefin may be 0.25-5:1 and of iodine 0.001-0.2:1, the iodine-liberating material being iodine, hydrogen iodine or an organic iodide.  Flow rates of olefin of 0.5-3 vol./vol/hr. and contact times of 0.1 second to several minutes may be used.  Many catalysts are specified, metal halides and phosphates are particularly preferred.  Where the catalyst is a metal, e.g. stainless steel, this may form the reaction chamber walls.

Title: New or improved method of and means for composing and igniting the charges in internal combustion engines
IPC: F02B23/04
Filed: 1924-09-29
Abstract: 222,519. Daimler-Motoren-Ges. Sept. 28, 1923, [Convention date]. Cycles. - In engines in which ignition is effected by the heat of compression, the charge of combustible mixture consists of two or more portions, the temperature of spontaneous ignition of one or more of these portions being below that of the temperature due to compression, and above such temperature for the remainder. Each charge portion is dealt with by its own admission and exhaust valves. A cylinder and piston of two diameters may be employed, there being sufficient clearance between the smaller portions of the cylinder and piston to permit of flame transmission to the larger part of the cylinder, mixing of the unignited charges being avoided by using compression spaces of such sizes that compression varies uniformly therein.

Title: Hydrogenation of alkali metal salts of dicyclopentadiene dicarboxylic acids
Filed: 1956-07-27
Abstract: A water-soluble alkali metal salt of a dicyclopentadiene dicarboxylic acid prepared by the process claimed in the parent Specification is hydrogenated by contacting an aqueous solution of the salt with hydrogen in the presence of a hydrogenation catalyst.  The dihydro or tetrahydro derivatives may be obtained. The hydrogenation is preferably carried out with a solution having a pH of 5.8 to 7.5 prior to and during the hydrogenation.  The pH of the aqueous salt solution is adjusted by the addition of acids such as formic, acetic, propionic, trifluoroacetic, oxalic, sulphuric or phosphoric acids. Salts of lower alkyl homologues of dicyclopentadiene dicarboxylic acid, such as methyl or dimethyl dicyclopentadiene dicarboxylic acids may also be hydrogenated. Specified hydrogenation catalysts are Adams platinum oxide, Raney nickel, nickel supported on alumina, silica, kieselguhr or carbon, cobalt, palladium, and iron.  In examples an aqueous solution of the sodium salt of dicyclopentadiene dicarboxylic acid is hydrogenated under various conditions of temperature and pH using a Raney nickel catalyst, and the product is acidified to give the free acid.

When the shaft 9 rotates, the friction between each frame and the shaft slightly rotates the frame until either the lubricating or the cleaning end, depending on the direction of rotation of the shaft, contacts with the rail. The lubricating device comprises a receptacle 1 containing stirring arms 18 fixed to a vertical shaft 17 driven through a crank shaft 21 and worm gearing from the wheel 22, the crank shaft 21 also operating a double-acting pump 24 to force lubricant through a hose 25 to the wick 27. The levers 12 may be controlled by the driver, or automatically, for operating the lubricating apparatus, by the coupling-bar of a trailer vehicle when taking curves. The brushes 29 rotate in the opposite direction to the road wheels and include two components, a narrow brush 30, Fig. 3, clamped between the discs 32, 321 which partly enter the rail groove to guide the brush 30, and a wider brush 31 for the tread. Each brush comprises a box 33, Fig. 5, having a central square hole 34 with cylindrical rollers 35 on its edges to facilitate axial movement of the brushes against the action of return springs 39, 39<1>, Fig. 3, and bundles of wires 37 fitted on pins 36 secured in the box and extending through circumferential holes. When wear takes place the longer wires may be substituted for the shorter ones. A combined cleaning and lubricating device may be mounted on each axle of the vehicle.

Keys 34 are located at the high pressure end of the rotor housing 14 in grooves formed in lugs 30 on the housing and in supporting members 26 on the stand 24 to permit lateral movement of the housing. Bearing housings 20, 22 separate from the rotor housing 14 are similarly fitted with keys 38, 40 respectively. A key 36 on the vertical centre line of the machine prevents lateral movement of the control part of the housing 14. Similar keys 42, 43 are fitted between the bearing housings 20, 22 and the stand 21. The bed or frame 44 may be cooled by pressure air or water and cooling medium may be circulated through the rotor and bearing housings through an inlet 46 and outlets 48.
