Abstract: 1489663 Measuring decay rate DEERE & CO 19 Aug 1975 [19 Aug 1974] 34454/75 Heading G1U A test signal 24, Fig. 2, representing the free but damped oscillation of a system under test (which may be mechanical or electrical) is displayed on a cathode ray tube 26 simultaneously with a reference ramp signal produced by an integrator 80, whereby by repeating the test sequence the slope of the ramp can progressively be adjusted by a potentiometer 60 to be the same as the decay rate of the test signal. As described, with a switch 36 in the position shown, an excitation signal 14 is applied via an appropriate coupling device 16 to the system under test. A test step is initiated by changing the position of the switch 36. The excitation signal is then removed from the test signal, and instead a test signal, from a suitable coupling member 22, and representing the decaying free oscillation of the system, is applied via a log amplifier 98 to the c.r.t. simultaneously with a ramp signal from the integrator 80 - the integrator being maintained in its reset state whilst the excitation signal is applied to the system under test. A test engineer can then see how closely the reference ramps signal matches the test signal and adjust the potentiometer 60 accordingly before making a further test step.

Abstract: 1527147 Tuning TV receiver SONY CORP 20 Aug 1976 [28 Aug 1975] 34828/76 Heading H3Q In a channel selection apparatus for a TV receiver during the programming operation in which a counter 40 is incremented/decremented to a count, converted by d#a converter 90 to produce a voltage to control a varactor in the tuning circuit, the count pulses are produced at a varying frequency so the tuned frequency varies substantially at an even rate, the varactor's inherent non- linearity being thus compensated for. During the programming mode the counter is incremented/decremented by coarse up/down pulses from unit 30 with a rate determined by unit 130 C operating on m.s. counter outputs B 13 -B 14  and clock stages A 10 -A 12  to produce via gates (Figs. 4, 7, not shown) three stepping rates for the counter. A similar arrangement, unit 130 F using B 13 -B 14  and A 13 , A 14 , A 14 ¸2, provides stepping pulses at a lower frequency for fine tuning. The counter state corresponding to a desired channel is written into memory 50. During the channel select mode the contents of a memory address selected by switches S 1-16  are read into the counter and d#a converter 90 produces a p.w.m. signal from the start of a clock cycle until the clock counter 20 reaches equality with the counter 50. The p.w.m. signal is filtered 92 to provide an analogue voltage to control varactor 100, also controlled by bond signals from bond memory 84.

Title: Improvements in or relating to the production of drying oil compositions from non-drying oils
IPC: C09F5/06
Filed: 1936-12-19
Abstract: Drying-oils are obtained by heating castor oil or like non-drying oil containing a hydroxylated fatty acid to above 200 DEG  C. in presence of the anhydride of a polybasic organic acid which readily forms the anhydride under the conditions, more than 1 mole of anhydride to 2 moles of the fatty acid of the oil being used.  Or the oil fatty acid may be treated and the product esterified with a polyhydric alcohol after separation of the polybasic anhydride.  A modified alkyd resin may be obtained by adding a polyhydric alcohol to the oil or fatty acid product without separation of the polybasic acid anhydride, and esterifying together.  The process may be carried out under reduced pressure or in presence of inert gas, and there may be present drying or semi-drying oils or their fatty acids, e.g. linseed and soya bean oils, and/or naturally occurring resins.  In examples: (1) 300 lb. of castor oil and 100 lb. of succinic anhydride are maintained at 270 DEG  C. for 4 hrs. in presence of carbon dioxide; excess succinic anhydride being filtered off after cooling; (2) 450 lb. of castor oil fatty acids are stirred with 225 lb. of phthalic anhydride for 1 hr. at 270 DEG  C. while carbon dioxide is passed through the mixture. The product is either (1) cooled, filtered, and esterified with glycerol to form a drying-oil, or (2) is converted to a resin by stirring with 80 lb. of glycerol for 3 hrs. at 230 DEG  C. while carbon dioxide is passed through.ALSO:Oil-modified alkyd resins are obtained by esterifying a polyhydric alcohol with the product obtained by heating caster oil or like non-drying oil containing a hydroxylated fatty acid, or the fatty acids of the oil, to above 200 DEG  C. in presence of the anhydride of a polybasic organic acid which readily forms the anhydride under the conditions, more than 1 mol. of anhydride to 2 mols. of the fatty acid of the oil being used. The process may be carried out under reduced pressure or in presence of inert gas, and there may be present drying or semi-drying oils or their fatty acids, e.g. linseed and soya bean oils and/or naturally occurring resins.  For example, 450 lb. of castor oil fatty acids is stirred with 225 lb. of phthalic anhydride for 1 hr. at 270 DEG  C., and the whole product with 80 lb. of glycerol for 3 hrs. at 230 DEG C., carbon dioxide being passed through the mixture throughout.
