Patent GB-569470-A (GB)
Title: Method of producing acetic acid esters of cyanohydrins
Filed: 1942-07-08
Abstract: Ketene is used to acetylate aliphatic cyanhydrins, e.g cyanhydrins of acetone, crotonaldehyde and trimethylacetaldehyde. In examples: (1) ketene is passed through three vessels in series charged with acetaldehydecyanhydrin; when the contents of the first vessel ceases to evolve heat, it is distilled to give the acetic acid derivative; (2) ketene obtained by the pyrolysis of acetone is passed into a benzene solution of acetonecyanhydrin; the product, a -acetoxyisobutyric acid nitrile is obtained by fractional distillation; (3) ethylene and propylenecyanhydrins are similarly treated with crude ketene.  The acetylated products on heating to remove acetic acid give the corresponding unsaturated derivative.

Title: Improvements in or relating to machines for extruding pipes
IPC: B21C25/02
Filed: 1937-04-08
Abstract: 490,079. Extruding earthenware &c. pipes HILL, S. D. April 8, 1937 No. 9953. [Class 87 (ii)] In a machine for extruding socketed pipes from plastic earthenware or other ma terial, of the type in which the plastic material is ex truded around a core anc through a bell-mouthed die with which co-operates a plunger die, a frame-work surrounds the axis of the bell - mouthed die and is mounted to be capable of axial movement in relation to this die, the frame-work having liquid-spraying devices directed towards the axis of the die. As shown, the extrusion press comprises a core 5 around which plastic material is extruded by a worm 12, through a bell-mouthed die 7 around a plunger die 8 carried upon a movable table 9. A framework 13 comprising liquid-spraying devices 14 is slidably mounted on bolts 15, the heads of which limit downward movement. The frame-work comprises three sets of tubes 38, 40, 42. The upper set 40 is connected through pipe 44 with air under pressure, and the lower set 42 is also connected to the supply of air, but through a valve 46. The set 38 is connected with a supply of lubricating liquid. Each spraying device comprises a nozzle 20, Fig. 4, having an air duct 21 connected by a pipe 41 with the set of tubes 40. Within the nozzle 20 is a jet 23 communicating through unions 26 with the sets of tubes 38. A plunger 30 connected to a piston 28 in a cylinder 27 is spring-pressed to project through an orifice 22 in the duct 21 and to close an orifice 24 in the jet 23. The inner end of the cylinder is in communication, through unions 29, with the sets of tubes 42. The arrangement is such that when the valve 46 is opened compressed air acts on the piston 28 to withdraw the plunger 30 and allow a blast of air to eject a spray of liquid from the orifice 24. The operation of the valve 46 is controlled by the table 9 which is provided with a hinged detent 49 adapted to engage a valve lever 48 as the table moves upwardly, whereby the valve is opened for a short time. On the return movement of the table the detent rides over the lever 48 without operating the valve. When the valve is opened the frame 13 is in its lowest position with the spraying devices tilted slightly upwards so that the jets of liquid spray are deposited over the outer surface of the core 5, the inner surface of the bell-mouthed die 7 and the outer surface of the plunger die 8. The pistons 28 of the spraying devices fit loosely in the cylinders or are provided with bleed orifices to facilitate return to normal positions.

Abstract: PURPOSE:To always ensure an even width of the ear cutting part regardless of the thickness of the attached developer and to prevent an uneven development, by giving a notched part to a magnet set at the developing position and then attaching a magnetic plate to the notched part. CONSTITUTION:A magnet 3 having a notched part 2 is set at the developing position of a magnetic brush developing device, and an ear cutting part 6 is provided between developers 4 and 5 to increase the width of a developing region. In such method of development, the width (w) of the part 6 becomes uneven to cause an uneven development in case the thickness of attachment of the developers 4 and 5 is small. In this connection, a magnetic plate 9 of SPCC having 2mm. thickness is provided at the part 2. As a result, the variation is secured for the distance between peaks for the magnetic field distribution, and accordingly the width (w) is made even at the part 6 to obtain a high-quality image free from any uneven development.

Filed: 1984-01-11
Abstract: PURPOSE:To prevent breakdown of liquid metal sodium valve having metallic expansion joint by constructing the drive shaft with slide drive shaft and valve body drive shaft and jointing through a slip mechanism with the valve body. CONSTITUTION:When metal sodium is solidified in a valve box 2, a handle 5 is turned to push down a slid drive shaft 4b thus to lower a slip shaft opening indicator 12b. But since a metal expansion/shrinkage joint 13 can not displace, reaction will occur in the valve drive shaft 4a. Since the fastening force of slip joint 15 is set lower than said reaction, the slip drive shaft 4b can not be stopped but slip through the slip joint 15 to prevent transmission of displacement of valve body drive shaft 4a.
