Title: Process for the production of dihalophenols
Inventor: PAYNE KENNETH RICHARD
IPC: C07C37/02
Filed: 1968-02-09
Abstract: 1,221,019. Process for the production of dihalophenols. COALITE & CHEMICAL PRODUCTS Ltd. 31 Jan., 1969 [9 Feb., 1968], No. 6574/68. Heading C2C. A process for the production of a dihalophenol comprises subjecting a trihalobenzene to alkaline hydrolysis at elevated temperature in a glycol containing from 2 to 4 carbon atoms in the molecule, and recovering glycol from the reaction mixture before liberating dihalophenol. In a preferred embodiment of the process a hydrocarbon additive e.g. petroleum ether, effective to entrain water evolved in the reaction and/or to hinder sublimation of the trihalobenzene, is used. The examples describe the preparation of dichlorophenols using trichlorophenols, ethylene glycol and caustic alkali as the starting materials.

Title: Method of compensating angular transmission characteristics electrically with particular functional ratio
IPC: G01S3/42
Filed: 1955-03-08
Abstract: 771,974. Compensating angular transmissions. YAO MUSEN KABUSHIKIKAISHA. March 8, 1955 [March 20, 1954], No. 6761/55. Class 40 (1). In selsyn devices used for automatic direction finding apparatus, particularly in aircraft, wherein the rotation of the loop antenna is transmitted to the navigator's seat by the selsyn device and wherein quadrantal, octantal and like errors are introduced due to the disturbance caused by closed circuits, vertical leading wires and the like, compensation for such errors is made by supplying electric current to the follower side of the selsyn machine for the purpose of producing on that side the magnetic field equivalent to the vectorial sum, which is sufficient to indicate the true angle, of the magnetic field of the driver side of the machine and correcting the magnetic field whereby the intensity of the horizontal or the vertical component or both of the magnetic field of the driver side could be compensated. As shown in Fig. 1, an auto-transformer 1 is introduced to step up the voltage output αEa of one phase a of the three phases of the selsyn transmitter. In the vector diagram shown in Fig. 2, it is assumed that due to quadrantal error, when the observational true angle is #, the angle measured by the selsyn will be γ for the position of a vector OP. The invention relies basically upon increasing the voltage output from the auto-transformer in the ratio a where α=RQ/RP. In Fig. 4, compensation for semicircular error as well as quadrantal error is introduced by an arrangement including an auto-transformer 5 across the A.C. exciter. In Fig. 7, gearing G1, G2 is used to compensate for the octantal error.

Filed: 1916-05-13
Abstract: 123,997. Williamson Kinematograph Co., and Williamson, C. M. May 13, 1916. Aeronautical photography.-Cameras for taking a series of photographs from aircraft are driven by a propeller opposed to the wind, and governing means are provided to maintain the driven mechanism at a constant speed without regard to the varying wind velocity. The hollow propeller shaft 1, Fig. 1, carries a longitudinally movable sleeve 2 which engages with the friction disk 3 freely mounted on the shaft 1. A centrifugal governor 5 is attached to the disk 3 and to the driven mechanism 6 by the springs 4 so that, when the speed becomes too high, the disk 3 is moved out of engagement with the disk 2. The speed may be varied by the operator by moving the disk 2 along the shaft by means of the rod 14, block 11, and the pin 12 carried by the disk. In a modification, the weights 5 are replaced by the. ring 15 attached to the disk 3 by the link 16. The position of the disk 2 may be varied by moving the collar 19 by means of the pins 20 working in the spiral slots 21 in the casing.

Title: Improved method of controlling the heat produced by a high frequency electric field in a bonded fibrous material
IPC: H05B6/46
Filed: 1943-04-30
Abstract: 567,380. Ply-wood &c. JABLONSKY, B. April 30, 1943, No. 6867. [Class 145 (ii)] [Also in Groups VIII and XI] In the manufacture of articles from fibrous material and an adhesive by electricallygenerated heat, the heat generated at various parts is controlled by using materials having different electric loss factors, i.e. dielectric loss, ohmic loss, eddy current loss, or hysteresis loss. Material with a higher loss factor may be used near the surface to compensate. for radiation losses or in thicker parts of the article. Added substances may be carbonaceous matter, graphite, carbon black, or acetylene black, an electrolyte or ionogen, e.g. an organic acid or a salt, or fine metal particles. The fibrous material may be in the form of loose fibres, wood laminµ, paper, textile fabric, or pulp. The adhesive may be a natural glue or resin, or a synthetic thermosetting or thermoplastic material, or a synthetic rubber. Fibrous laminµ may be interleaved with solid films of adhesive. An article may be built up of fibrous laminµ of different thickness, an adhesive of high electric loss being used for bonding the thick laminµ, and lower loss for the thinner laminµ. Long laminµ may be interleaved with shorter laminµ in places, an adhesive of high electric loss being used for the short laminµ and lower loss for the longer laminµ. When an article is built up of laminated boards, the boards may be bonded with a low-loss adhesive and united together with a higher loss adhesive. The frequency may be in the range of megacycles, or may be reduced to 50.

A portion of a body 24 is shaped by frictionally engaging the portion with a transporting member 16, applying a first pressure by means of a compressible member 114 on which the body can slide, and applying a second pressure to the member 16 so as to press the portion into a die 22, the pressures being sufficient to set up a hydrostatic pressure condition in the body portion. The workpiece 24 is preferably tubular and has a flange 26 upset on one end so as to form a waveguide. A pressure sleeve 114 of low friction resilient and deformable material, made in one or two parts, is placed around the workpiece 24 which contains a mandrel 16, and the sleeve is compressed on to the workpiece by a forcing member 120 which has a tapered surface with serrations or teeth 121. After preloading the member 120 by bolts 132, the mandrel 16 is moved downwardly and simultaneously pressure 139 is applied to the member 120. This produces a hydrostatic condition in the workpiece 24 causing its extrusion through the die 22 and into the chamber 156 to form the flange 26. Pressure is maintained on the material in chamber 156 by a back-up die 160 loaded by pressure liquid supplied by pump 60.
