Title: Process for the oxidation of carbon monoxide and hydrocarbons
IPC: C01B32/50
Filed: 1972-11-14
Abstract: 1366217 Exhaust gas catalyst KNAPSACK AG 14 Nov 1972 [20 Nov 1971 29 Dec 1971] 52528/72 Heading B1E [Also in Division F1] A process for the oxidation of carbon monoxide and hydrocarbons, particularly those contained in the exhaust gas of i.c. engines, with oxygen-containing gases to carbon dioxide and water, which comprises effecting the oxidation at temperature between 100 and 700‹C in contact with a catalyst consisting of one or more oxides of copper, manganese, nickel or cobalt, the catalyst being on a support consisting of at least one alkaline earth aluminate. Preferably the oxidation is effected at temperatures between 150 and 600‹C. The support is an aluminate of barium, calcium or strontium and may additionally contain 2 to 30% by weight of one or more silicon containing compounds, e.g. silicon dioxide or magnesium silicate, preferably talc. The support may also contain between 2 and 30% by weight, preferably 5 to 20% by wt. of titanium dioxide. The support may also contain both silicon dioxide and titanium dioxide, the total amount of the two additives being 2 to 30% by weight. The carrier-supported catalyst is made by impregnating the alkaline earth metal aluminates with an aqueous solution of copper, manganese and nickel or cobalt salts of volatile acids, the quantity of solution being just sufficient to be completely absorbed by the aluminates, then heating the resulting mass to temperatures between 300 and 600‹C to decompose the salts and finally annealing the resulting catalyst at temperatures between 600 and 1200‹C. The metal salts may be nitrates of volatile acids, which are decomposed at temperatures between 350 and 450‹C and then annealed at temperatures between 600 and 1000‹C.

Title: Methods of and or apparatus for joining timber members
IPC: B27F7/15
Filed: 1973-11-13
Abstract: 1437513 Nailing presses AUTOMATED BUILDING COMPONENTS (NZ) Ltd 13 Nov 1973 [16 Nov 1972] 52650/73 Heading B4C Apparatus for joining timber members using spiked connector plates comprises a pair of platens 18, 2 which receive spiked plates from magazines 20, 21 and move them to a position where they can be embedded in the timber by hydraulic cylinders 19. As shown for joining two pieces of timber end to end, the apparatus is provided with an opening 4 into which the first timber is fed, positioned longitudinally against a spring-loaded detent 8 and clamped against a support 12 by a bar 5 under the pressure of a hydraulic or pneumatic cylinder 6 mounted at one end. When the second timber is fed up to the first timber and the cylinder 7 at the other end of the bar 5 operated, a spring loaded pivoted arm 13 on the bar 5 pivots to force the second timber towards the first as the bar clamps the second timber against the support 12. The cylinders 19 are then actuated to press the platens 18, 2 towards each other and embed the spiked plates which have been previously positioned as described below. Each platen is freely rotatable through 180 degrees to carry the spiked plates from the magazines 20, 21. The drive for rotating the upper platen 18 may be the same as that for the lower platen 2 and may consist of a friction wheel 33 driven by a motor 32 hinged for pivotal movement about pivots 36, a pair of notches 40, 41 being provided in the platen for cooperating with a spring catch 3. A switch 38 starts the motor 32 when contacted by the pivoting of the motor and a switch 39 stops the motor 32 when contacted by a projection 44. As the platen 18-approaches the magazine 20, a retaining cover 26, Fig. 5 is pivoted clear by the engagement of the platen with an adjustable actuating member 29 so that the uppermost spiked plate can move out of the magazine and attach itself to magnets 23 on the platen. The spiked plates in this magazine 20 are urged upwardly towards the cover by a spring or a counterweight while the spiked plates in the magazine 21 fall by gravity. After the embedding operation the platens are moved apart by the cylinders 19, such movement serving to close the magazines and pivot the driving motors into position for stepping round the platens ready for the next pressing operation. The cylinders 6, 7 are then actuated to release the work. If three timbers are to be joined ina T formation, the arc of movement of the platens may be different from the 180 degrees.

[Also in Division F2] A chain hoist includes a load regulator 20 operatively interposed between the input drive chain wheel 17 and the output wheel for a load chain 12, to limit the maximum load-raising capacity, the regulator comprising a detent coupling means operable to maintain input and output sections thereof connected unless a predetermined maximum hoist load is exceeded whereupon the coupling becomes disconnected. The coupling comprises rollers located in angularly spaced radial slots in retaining plates 34, 35, 36 and spring-biased into engagement with detents in a surrounding annular detent plate 42 secured to the chain wheel 17, the plates 34, 35, 36 being bolted to a hub 28 of a Western brake mechanism interposed between the regulator coupling and the output chain wheel. The contours of the detents in the plate 42, the rate of the springs biasing the rollers and the number of rollers are selected to determine the maximum load, the exceeding of which causes the rollers to be forced out of the detents thereby generating a clicking audible signal indicating an overload condition. A wave washer 45 gripped between a plate 38 movable with the plates 34, 35, 36, and the side of the detent plate 42, offers resistance to rotation of the chain wheel 17 once the coupling has been disconnected, to prevent sudden free rotation of the wheel 17. In the modification of Figs. 3 and 4 (not shown), the coupling rollers are mounted in radial slots in the brake mechanism and the detents are formed in the chain wheel.
