Abstract: 1,021,152. Electromagnetic relays. SQUARE D CO. May 6, 1963 [July 2, 1962], No. 17740/63. Heading H2B. A moving contact bridge assembly 98, 100, 101, Fig. 17 (not shown), is rotatable about a driving bar 92 of an insulating contact carrier 86 to change it from the normally open (Fig. 17, not shown) to the normally closed position (Fig. 19, not shown). The contact bridge 98 co-operates with fixed contacts 116. The arrangement is such that in the case of normally open contacts the bridge engages the fixed contacts when the carrier has completed the first half of its stroke and the spring 101 is compressed during the second half of its stroke. Likewise, with normally closed contacts, the carrier will complete half of its stroke before the contacts disengage and the spring 101 will be compressed during the final part of its stroke. Thus reversing of the contact bridge from the normally open to the normally closed position has no effect on the overall bias of the contact carrier. In the relay shown (Fig. 2, not shown), an armature carrier 50 is received in grooves 59, 60 in a housing 26, an encapsulated coil 16 is received in slots 69 in the housing, an E-shaped core 16 with shaded poles is secured in the housing by brackets 73, the contact carrier 86 is mounted on extensions 49 of the armature carrier 50, blocks 22 carrying the fixed contacts are mounted on either side of the contact carrier and are located by lugs 107a engaging in the slots 69 of the housing, and the housing is closed by a cover 24 held in position by two spring biased brackets 28. In Fig. 4 (not shown), the ends 73a of brackets 73 engage shoulders 85 in the housing and are maintained in position by compression springs 74. The core 76 is secured to its support 71 by a spring and is provided with sponge rubber buffers 79, 80 The armature 52 is mounted by a flat spring 54 in its carrier 50. The relay may be manually operated by a push button and may have four poles as shown or eight poles arranged in two superposed rows of four (Figs. 14 ... 16, not shown). The cover has a number of holes in it for the inspection of contacts.

Title: Preparation of bis-2:2-(p-hydroxyphenyl propane
IPC: C07C37/20
Filed: 1958-06-03
Abstract: Bis - 2,2 - (p - hydroxyphenyl) propane is produced by condensing acetone with phenol in the presence of concentrated sulphuric acid (i.e. acid of at least 85% strength) diluted with acetic acid, using as catalyst a mercapto-alkane sulphonic acid or a salt or ester thereof.  The catalyst preferably constitutes 0.1 to 5% by weight of the reaction mixture.  The acetic acid (glacial) is preferably equal in weight to the sulphuric acid employed.  The mol. ratio of phenol to acetone should lie within the range of 2 : 1 to 8 : 1.  The condensation temperature is preferably between 15 DEG  C. and 25 DEG C.  In Example 1, sodium b -mercaptoethanesulphonate is employed as catalyst.  The pasty condensation product is poured into water, and crystalline bis-(hydroxyphenyl) propane contaminated with phenol is obtained. The crystals are centrifuged, and washed with water.  They are then suspended in water the residual acidity is neutralized with sodium acetate, and the product is heated at 90 DEG  C. with agitation until the bis-(hydroxyphenyl) propane is liquefied.  The mixture is cooled to 30 DEG  C. with agitation; and the crystals are centrifuged and washed with water.  Residual phenol is removed from the product by steam-distillation.  The product is dried at 80 DEG C. and may, if desired, be recrystallized from chlorobenzene. In Example 2, sodium o -mercaptopropanesulphonate is used as catalyst.

Filed: 1970-04-15
Abstract: 1,237,057. Measuring friction, electrically. H. KRANTZ VERWALTUNGS G.m.b.H. April 15, 1970 [May 29, 1969], No.17917/70. Heading G1N. [Also in Divisions D1 and F2] In a method for the continuous determination of the lubricant requirement of a moving sliding surface by measuring the current consumption of a motor, the sliding surface is traversed, transversely to its direction of movement, by a sensor, the latter being urged towards the sliding surface at a constant pressure, and the power requirement for moving the sensor at a constant surface pressure is measured as the load current of a direct-current motor. In an embodiment a clip body 1 of a fabric treating machine, is connected to a link 2 of a chain which runs in a rail 3 comprising a horizontal web 4 and a vertical web 5. A sliding surface 7 of a yoke 8 of the clip body 1 abuts a sliding surface 9 which is formed in a groove 6 of the vertical web 5, the sliding surface 7 being urged towards the sliding surface 9 be means of springs 10, 11. A sensor 13 mounted on a rod 14 is guided by pulleys 19, 19 and 20, 20 mounted on a plate 18, the latter being pivoted at 17; and is urged towards the sliding surface 7 by means of a spring 24 which is connected to the plate 18 and to a member 25 carried by the web 5. The rod 14 is reciprocated by an electric motor (not shown), via an eccentric 23 and a crank 22. The current consumption of the motor is proportional to the lubricant requirement of the sliding surface 7 and the amount of lubricant supplied can thus be determined and, by means not described, can also be controlled. A roller 16, carried by the web 5, serves to support the sensor against horizontal friction forces caused by movement of the yoke 8.

Title: Improved process for extracting the unsaponifiable fraction from fatty bodies
IPC: C11B3/16
Filed: 1963-05-09
Abstract: The unsaponifiable fractions are extracted from fatty bodies, e.g. maize oil or corn oil, by subjecting a mixture of the fatty body and a solvent for the unsaponifiable fraction to ultrasonic waves and then separating from the mixture the solvent containing the dissolved unsaponifiable fraction from which the latter may be recovered.  The extraction takes place at up to 70 DEG  C. and ultrasonic frequencies of about 17 kilocycles are used.  Specified solvents are ethyl alcohol, ethyl ether or butyl ether.  In the example, corn oil and ethyl alcohol are mixed and after treating at 70 DEG  C. with ultrasonic frequencies, the unsaponifiable fraction in the solvent is separated by decantation, any saponifiable substance present is then removed by saponification and aqueous washing, a solvent is added to the residue and pure unsaponifiable material is obtained by evaporating the solvent.

Title: Separation of delta-tocopherol from vegetable oils
IPC: C07D311/72
Filed: 1947-07-11
Abstract: A concentrate of mixed tocopherols is obtained by the high-vacuum distillation of a vegetable oil in the conventional manner, e.g. at a pressure of 0.01 mm. to 0.001 mm. and a temperature about 150 DEG  to 250 DEG  C.  In example (5), soya bean oil is distilled at 150-170 DEG  C. at 0.003 mm. pressure to obtain mixed a -, g - and d -tocopherol.ALSO:d -Tocophenol, hithertofore unknown, is obtained by treating a vegetable oil, e.g. soya bean oil, to separate a mixed tocopherol concentrate and then separating d -tocopherol from the mixed concentrate by fractional crystallization and/or chromatography. The methods by which the tocopherol concentrate may be obtained from the vegetable oil are high-vacuum, unobstructed-path distillation, selective adsorption, solvent extraction, saponification and combinations thereof.  When using high vacuum distillation the phosphatide sludge is first removed and the mixed concentrate obtained as a 1 per cent "cut" of the distillant. In separating the mixed concentrate by fractional crystallization the tocopherols are esterified with an acid halide such as palmitoyl chloride, lauroyl bromide, myristoyl iodide, dinitrobenzoyl chloride and phenylazobenzoyl chloride.  The a -, b - and g -tocopherols are precipitated whilst the d -tocopherol remains in solution. Alternative d -tocopherol is obtained by the usual chromatographic methods.  Detailed examples are given.
