Title: A method for the production of polyhydricalcohols
IPC: C07D309/10
Filed: 1958-05-28
Abstract: In a method for the production of polyhydric alcohols by the reaction of formaldehyde with another aldehyde or ketone in an alkaline solution, the alkali metal or alkaline earth metal formate is removed from the polyhydric alcohol by evaporating at least half of the water contained in the mixture and then centrifuging the mixture at a temperature which is sufficiently elevated to lower the viscosity of the mixture sufficiently to separate a substantial proportion of the formate from the alcohol. The process is particularly applicable to the purification of trimethylolpropane, trimethylol ethane, 2,2,6,6-tetramethylolcyclohexanol, and 2,6,6,6-tetramethylol tetrahydro-g -pyranol.  Suitable temperatures for carrying out the centrifuging lie within the range 70 DEG C.-100 DEG C., preferably 85 DEG C.-90 DEG C.  The polyhydric alcohol which is separated in the centrifuge may be further purified by dissolving or dispersing in water and passing in succession through a cation exchange unit or an anion exchange unit.

Title: Improvements in and relating to tuning arrangements for wireless-receivers and the like
IPC: H03J5/06
Filed: 1943-10-18
Abstract: 569,451. Indicating - apparatus. PHILIPS LAMPS, Ltd., and RICHARDS, C. L. Oct. 18, 1943, No. 17124. [Class 106 (iv)]' [Also in Group XXXVI] A tuning arrangement for wireless receivers comprises a click mechanism in which at least one of the click elements is resiliently mounted and is adapted to be urged electromagnetically out of its rest position into a position giving a greater degree of engagement with the other click element. As shown in Fig. 2, a tuning shaft 5 carries a disc 8 on which are adjustably fixed a number of click arms 9 which co-operate with resiliently-mounted members 25 to locate the shaft 5 in a number of selected positions. The members 25 are in the form of polepieces of an electromagnet 26, pivoted at 32 to a fixed frame 33. The polepieces 25 are bridged by a non-magnetic yoke 27 which is biassed to a central position by springs 28 carried on a fixed frame 30. In this position, the degree of engagement of the arm 9 between the members 25 is small enough to allow the arm 9 to be engaged and disengaged readily by turning the tuning knob. When a desired position is reached, a switch, not shown, on the tuning knob is released to cause energization of the electromagnet 26. As arm 9 is of magnetic material, this causes the arm to engage deeper b,etween elements 25 where the opposing surfaces are parallel. This gives a more precise location of the arms 9 and they are no longer displaceable by moving the tuning knob. The arms 9 have a pivoted engagement with a triangular aperture 21 in disc 8 and are fixed in the desired angular position by a screw 23 working in a slot 22. The shaft 5 carries a drum, Fig. 1 (not shown), driven by cords from the tuning knob. Further cords drive an index for a tuning scale. According to the Provisional Specification, the magnet and polepieces may be resiliently mounted on the rotatable disc, the click pins being stationary.
