Title: Process for the preparation of transformation products from oils obtained from fatty oxyacids or substances containing the same
IPC: C10M101/04
Filed: 1932-12-19
Abstract: Oils derived from fatty hydroxyacids, or substances containing them, are heated with a polymerization catalyst, and the product is heated under reduced pressure with an alcohol, preferably in the presence of an esterification catalyst.  The first treatment is effected at 150--300 DEG  C. at atmospheric or somewhat raised or reduced pressure in the absence of alkaline compounds and alcohols and with or without the use of a current of inert gas; the polymerization catalyst may be a compound of an element of the third, fourth or eighth periodic group, and may be supported on active charcoal.  As esterification catalysts in the second treatment, use may be made of esters of mineral acids, particularly sulphuric esters of alcohols and of organic hydroxyacids.  According to the conditions, the products are partly or totally soluble in hydrocarbons and mineral oils; they may be used as lubricants, alone or with other lubricants. In the example, castor oil is heated with aluminium hydrosilicate at about 270 DEG  C. and atmospheric pressure for a period not exceeding one hour, and the product is heated with a little glycerol to the same temperature at a pressure of about 20 mm. in the presence of hydroxyoleic acid sulphuric ester or other esterification catalyst. The Specification as open to inspection under Sect. 91 states that the two treatments may be effected in one operation, without isolation of the intermediate product, and that the treatments may be applied to free hydroxy fatty acids or mixtures containing them.  It states also that organic or inorganic acids or acid salts may be added during the first treatment, and that an alcohol need not be added in the second treatment.  It includes also a further example in which a mixture of colza oil and castor oil is heated to 190 DEG  C. at atmospheric pressure with aluminium hydrosilicate, and the product is heated to 230 DEG  C. in vacuo with glycerol in the presence of hydroxyoleic acid sulphuric ester. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to television arrangements
IPC: H04N5/213
Filed: 1956-12-04
Abstract: 807,291. Radio receiving systems. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 4, 1956 [Dec. 7, 1955], No. 37036/56. Class 40 (5). In a receiver for negative-modulation television signals, in order to reduce the effect of noise impulses on the synchronizing signals, the video signal is combined in opposite sense with the video signal amplified, the amplitude of the noise impulses in the amplified video signal being substantially limited to the level of the peaks of the synchronizing signals. The intermediatefrequency television signal is applied to a detector 2 whose output across a resistor 5 is amplified by a valve 3 so that a signal of opposite sense is produced across the resistor 7. This amplified signal is applied via a resistor 11 and diode 10, which limits the level of the synchronizing pulses and the noise impulses to earth potential, to one end of a potentiometer 12, the other end of the potentiometer being connected directly to the detector output resistor 5. Consequently, a combination of the two signals is produced in a certain amplitude ratio which is determined by the position of the potentiometer tapping 16, which is so adjusted that the resultant noise impulses lie below the black level. The circuit is only effective for noise impulses which initially exceed the level of the synchronizing pulses but it is stated that in practice this is satisfactory. The combined signal at the tapping 16 is applied to a first control grid of a valve 15 which is arranged to be conductive only during the occurrence of synchronization pulses. The signal appearing at the anode of the valve 3 may also be applied in known manner to a second control grid of the valve 15 but this is not essential.
