Title: Improvements in wood cutting and sand-papering machines
IPC: B27C9/00
Filed: 1929-03-13
Abstract: 307,841. Loepfe, M. T., (Assignee of Giezendanner, R.). March 14, 1928, [Convention date]. Void [Published under Sect. 91 of the Acts]. Sawing.-A combined sand-papering and sawing machine has the saws arranged behind and above the operative stretch of sand-paper so as to avoid interference with the sand-papering operation. The continuous band of sandpaper k passes round the two pulleys i, i<1> and is kept taut by a weight acting on the sleeve mounted on the shaft l. It can be pressed down by the shoe h on to work carried on the table g which can be on guides b through the screw c<1>. When the band of sandpaper is removed the two saws t rotated by the shaft r can be used to cut work supported on the packing pieces B. The saws are adjusted in lateral position by the wheels y acting through a rack and pinion. A ventilator z fitted on the shaft of the motor g keeps the machine free from wood-dust.

Methanol.-In the treatment of organic compounds in the presence of oxide catalysts which have both a hydrating and dehydrogenating effect, a repressive agent is added to the catalyst to counteract its normal dehydrogenating effect. Examples of the use of the method are the hydrolysis of methyl chloride to methanol, in which repressive agents in the form of acidic oxides are added to the catalyst to prevent the formation of dimethyl ether, and the hydrolysis of dimethyl ether, in which aluminium sulphate is added to an alumina catalyst to prevent the formation of formaldehyde. Oxide catalysts suitable for hydration are those of aluminium, thorium, zinc and uranium and repressive agents which mav be added to prevent hydrogenation are acidic oxides in the form of acids, acid salts, anhydrides, and ammonium salts.
