Title: Manufacture of unsaturated aldehydes
IPC: C07C45/51
Filed: 1927-03-17
Abstract: 267,954. Rupe, H. March 22, 1926, [Convention date]. Unsaturated aldehydes are obtained by treating with acid or an acid derivative an acetylene alcohol which contains a free hydrogen atom in the acetylene group and in which the hydroxyl group is attached to a carbon atom next but one to that to which the free hydrogen atom is attached. The acetylene alcohols may be cyclic, aliphatic or aromatic-aliphatic, whilst the acid may be, for example, formic acid, acetic acid, hydrochloric acid, sulphuric acid, or acetic anhydride. The products are useful for the manufacture of pharmaceutical preparations and perfumes. An example is given of the preparation of cyclohexylidene-acetaldehyde by heating 1-ethinylcyclohexanol-(1) with formic acid. In similar manner, #-methylcinnamic aldehyde can be obtained from ethylmethylphenylcarbinol, isopropylidene-acetaldehyde from ethinyldimethylcarbinol, sec-butylidene-acetaldehyde from ethinylmethylethylcarbinol, 3-methycyclohexylidene-acetaldehyde from 1-ethinyl-3-methylcyclohexanol-(1), and 2-methyl- 5-isopropyl-cyclohexylidene-acetaldehyde from 1- ethinyl-2-methyl-5-isopropyl-cyclohexanol-(1). The acetylene alcohols used as starting materials may be made by the action of acetylene on the sodium compound of a ketone. The semicarbazones of cyclohexylidene-acetaldehyde, 3-methylcyclohexylidene-acetaldehyde, 2-methyl-5-isopropylcyclohexylidene-acetaldehyde, isopropylidene-acetaldehyde, and sec-butylideneacetaldehyde are described. The oxime and bisulphite compound of cyclobexylidene-acetaldehyde are mentioned.

Title: Improvements relating to mechanisms operated by fluid pressure for lifting implements of agricultural tractors
IPC: A01B63/10
Filed: 1939-03-08
Abstract: 525,520. Valves. INTERNATIONAL HARVESTER CO. OF GREAT BRITAIN, Ltd. (International Harvester Co.). March 8, 1939, No. 7567. [Class 135] [Also in Group I] In an agricultural implement in which tools are operated in succession hydraulically or pneumatically, the fluid supply is connected to the inlet and outlet sides of the pump, and a controlling valve, when open, permits fluid to circulate at a pressure insufficient to operate the tools, but when the valve is closed fluid passes from the outlet side of the pump to operate the tools in succession. The flow of fluid is controlled by a spring-pressed valve 64, in a chamber 63 opening into the passage 56. When this valve is open fluid is drawn by the pump through the pipe 51 and delivered again into the casing 30 through the chamber 63 and no pressure is communicated to the tool cylinders. When the valve 64 is closed the tools are raised. The closing of the valve 64 is effected by a handle on the tractor connected to an arm fixed to a shaft 78 to which is also fixed a toggle mechanism 76, 75 connected to a pivoted arm 72 carrying a projection 73 provided with a flange 74. Operation of the handle presses the flange 74 against the spring 65 and closes the valve 64. When the tools have been lifted to their fullest extent, the pressure in the passage 56 lifts a piston 66 and causes a rod 70 to press against the link 76 and break the toggle and so release the valve 64.

Abstract: 480,632. Delivering materials from hoppers. DAVIDSON & CO., Ltd. (Canadian Sirocco Co., Ltd.) March 18, 1937, No. 7996. [Class 78 (i)] [Also in Groups II and XXIX] A discharge flap valve 4 for a dust-collector 1, particularly for use in connection with cyclone separators of the type described in Specification 196,537, [Class 23], is made of flexible or resilient material secured at its top edge to the casing by bolts 6, and stiffened by transverse members 5. The outlet 3 from the casing 1 is inclined to the vertical so that the weight of the valve tends to keep it closed. A spring 7 is also arranged to hold it closed, and this is aided by the low pressure in the collector. The separated dust drops through the passage 2 and collects in the lower part of the casing 1 until its pressure causes the valve 4 to open as shown in Fig. 2. If more dust accumulates the valve will open up further until a steady flow of dust is maintained. In a modification the casing may be enclosed in a housing provided with windows for inspection and a door permitting access to the valve. In addition to its use with centrifugal dust - collectors, the valve may be used to control the flow of wheat or ground substances from hoppers or similar containers.
