Title: Improvements in or relating to wood rosin
IPC: C11D15/00
Filed: 1941-07-01
Abstract: 552,642. Treating wood rosin. HERCULES POWDER CO. July 1, 1941, No. 8291. Convention date, Sept. 16, 1940. [Class 95] Wood rosin is made more suitable for use in the manufacture of rosin size, by heating it at 250‹C. to 350‹C. for a period of time sufficient to eliminate its property of forming a crystalline acid abietate salt on treatment with alkali, but insufficient to change the crystallizing character of the rosin itself. The first effect of the heating is to reduce the specific rotation of the rosin, after which a reversion or an increase of the specific rotation, in a positive direction, occurs, and heating should be stopped before the increasing specific rotation exceeds+20 degrees. An example is given in which refined wood rosin of K grade is heated, in a non-oxidizing atmosphere, at 300‹C. for 4-5 minutes.

Filed: 1938-03-19
Abstract: 512,910. Electromagnets. LIST, H. March 19, 1938, No. 8515. [Class 35] [Also in Group XXXVII] An electromagnet comprises a stator in the form of a pot 1 with a central core 3, and a disc armature 8 mounted to oscillate in the stator, the stator and armature which are of approximately equal cross-sectional area being provided with teeth 17, 9 which define the limit of the armature rotation, means being provided to return the armature when the winding is deenergized. The cross-section of the magnetic circuit is preferably large enough to ensure that no part will reach saturation, and the crosssection of the winding 4 is preferably circular or square. As shown in Fig. 1, the stator and armature have eight poles or teeth and the movements of the armature are transmitted by way of a pin 27 thereon projecting through a slot 26 in a cover 7. As shown applied to a relay, Fig. 4, the base 3a and core 3 of the magnet are in one piece and the yoke 1 is formed with poles 17. The armature 8 is carried by a shaft 11 journalled in a bore in the core 3, which bore has an adjustable thrust bearing 24, 14, and a ball or other bearing 16. The thrust ball 14 may be located within a bore of reduced section and co-operates with a stub on the end of the shaft. The stub prevents tilting of the armature. The armature has an integral boss 10 carrying an arm 30 provided with a roller which acts on a cam surface on a spring-returned pivoted lever 32. The lever 32 is connected to a relayactuating member 37. The relay comprises four upper and four lower stationary contacts 36 and a moveable bridge consisting of rollers 35. Flux passes radially between the armature and the stator, but the poles may be arranged in the form of one or more co-operating steps so that the direction of flux is partially axial. Fig. 6 shows a modification in which the body part of the magnet is formed by a stamping or drawing process. Discs 5, 6 of the shape shown are secured to the core 3 or may be integral therewith to preserve constancy of cross-sectional area of the magnetic circuit. Distance pieces 21 may be inserted between the thrust ball 14 and the armature shaft to provide for axial adjustment of the armature. The armature may be laminated. A construction is described in which two opposed pot magnets have a common pole-ring and a single armature. The coil conductors may have a square cross-section and may be of aluminium or alloys thereof insulated with a coat of lacquer or oxide.
