Patent GB-123792-A (GB)
Title: A Process for Converting Linseed Oil Fatty Acids or any other Fatty Acids of Drying or Semi-drying Oils into well Drying Oils.
Filed: 1918-02-01
Abstract: 123,792. Boehm, Ltd., F., and Reihl, C. A. Feb. 1, 1918. Varnishes and paint vehicles.-Fatty acids derived from drying and semi-drying oils are converted into a well-drying oil by prolonged heating, at a temperature slightly below their boiling point, until polymerisation sets in. The operation is effected in a reflux condenser and takes 18-24 hrs. The process is accelerated by blowing oxygen through the fatty acids, and by adding a small quantity of copper, nickel, cobalt, or other finely-powdered metal or oxide to the charge. Polymerization is aided by the addition of Chinese wood oil, together with a small quantity of a soap of an alkaline earth or a linoleate, e.g. linoleate of calcium, aluminium or magnesium. The fatty acids of linseed, cottonseed, niger, and castor oils may be used. The products are used as linoleum oil, or, diluted with turpentine or turpentine substitute, as a waterproofing oil, paint, or varnish. Reference has been directed by the Comptroller to Specification 122,696.

Filed: 1947-01-28
Abstract: 632,999. Automatic speed control systems. TREWEEK, K. H. Jan. 28, 1947, No. 2636. [Class 38 (iv)] In an electrical regulating system a movable member of a polarized relay is maintained in a state of oscillation to repeatedly reverse the input to the field or armature of an electric motor by the inductive effect of a current controlled by the motor. In Fig. 1 the field excitation of a reversible D.C. motor 2 is controlled by contact 1 of a relay 3 which is kept vibrating by a voltage fed back from a D.C. generator 4 driven by the motor. This voltage opposes, in a circuit including coil 5 of relay 3, a D.C. control voltage applied to terminals 7 and 8, the magnitude and polarity of which determines. the speed and direction of motor 2 and hence the magnitude and polarity of the output of generator 4. The following modifications are referred to: (a) control and feedback voltages applied to separate windings of the relay; (b) further control voltages applied to other relay windings; (c) feed-back voltage obtained from the armature of the motor, in which case the generator is dispensed with and the relay controls the motor armature instead of the field; (d) a mechanical control force applied to the relay armature in place of the control voltage.

Abstract: 1,254,413. Optical apparatus. SOUTH AFRICAN INVENTIONS DEVELOPMENT CORP. Jan.20, 1970 [Jan.21, 1969], No.2719/70. Heading G2J. The mean diameters of particles or fibres are measured by locating a sample of randomly disposed particles of uniform diameter in a light path to produce a diffraction pattern, viewing the diffraction pattern against a target from the scale of the sample opposite to the light source, moving the target and the sample relative to each other in an axial direction with respect to the light path to bring a reference mark on the target into predetermined relationship with a selected zone of the diffraction pattern, and translating the spacing between the target and sample when the reference mark on the target is in the predetermined relationship with the selected zone of the diffraction pattern, into mean particle diameter. Suitable apparatus comprises two telescopically mounted tubular members 1, 2. The smaller diameter member 1 has one end blanked off and adjacent the other end a target 3. The target is opaque but has a central aperture 4 and a translucent annulus 5 concentric with aperture 4. A light source 6 is mounted in tube 1 to shine through aperture 4 of the target 3. The samples to be measured are located in a transparent holder 10 axially located on the end of tube 2 distant from tube 1. An aperture 9 in that end of tube 2 enables the samples to be illuminated. When viewed a diffraction pattern is seen superimposed on target 3. The outer edge of the translucent annulus 5 acts as a reference zone. The two tubes are moved relative to each other to make this zone and a desired diffraction ring coincident. The tube 1 can be suitably calibrated so that the mean diameters can be read off directly.
