Abstract: 1,157,528. Insulin derivatives. ROUSSELUCLAF. 5 Oct., 1966 [5 Oct., 1965], No. 44563/66. Heading C2C. Insulin derivatives are prepared by reacting insulin with a dicarbonyl compound in an aqueous medium at pH 7À5-8À5 and adjusting the pH to 5-6. The dicarbonyl compound may be a diketone, a dialdehyde, a ketonic ester, a diester or a keto-aldehyde. The dicarbonyl compound blocks the guanidyl groups of the arginine residue and the blocked groups are not cleavable under conditions serving to hydrolyse an imine or enamine. The dicarbonyl compound also blocks the free amino groups of the lysine residue and/or the N-imino group of the histidine ring to form residues which are cleaved by mild hydrolysis, e.g. with 2NHC1. The arginine residue blocked with acetonyl acetone probably has the structure and the modified lysine unit the structure The compounds show anabolic activity with no appreciable glycaemic effect.

Title: Control circuits
IPC: H02P6/24
Filed: 1970-09-22
Abstract: 1316456 Control of A.C. motors SPERRY RAND CORP 22 Sept 1970 [1 Oct 1969] 45001/70 Heading H2J A brushless motor is started in the clockwise direction when a signal is applied to terminal 19 whereby transistor 21 becomes conductive and capacitor 41 is charged through transistor 31. The voltage applied to output terminal 43 increases gradually until it becomes sufficient to actuate sensors in the motor to be controlled so that it then forms an effective command signal. Transistor 61 conducts when transistor 31 is turned on to prevent any signal applied to a counterclockwise input terminal 79 from actuating a transistor 49. When transistor 31 is turned on, a voltage is applied to circuit 69 to remove a brake. When the signal is removed from the input terminal 19, transistors 21, 31, are turned off, the transistor 61 being turned off after a brief delay, and the output to the braking circuit 69 is removed. The time constant of the circuit 69 ensures that voltage is removed from the command output terminals before braking is applied. If a signal is then applied to the terminal 79 after a considerable delay, the switching circuit in channel 11 is disabled and the brake is released. The voltage at the counterclockwise output terminal 75 gradually increases to the level for effective operation of the motor. If the counterclockwise signal is applied too soon after termination of the clockwise signal, the counterclockwise switching circuit does not respond until after the motor has stopped.

Title: Production of quartz powder
IPC: C03C1/02
Filed: 1961-12-15
Abstract: <PICT:0939185/III/1> A method of making white quartz powders from quartz-containing sand comprises thermally treating the sand with metallic salts that form white SiO2-compounds and grinding the reaction product, wherein the metallic salts are added directly to a hot combustion and reaction chamber.  In the example sand is supplied to a revolving tube (1) through a feeder (10) which is preheated in stages by auxiliary burners (9).  The sand advances to casing head (13) which has a constriction (12) which accumulates the sand at the hottest part of the tube where the reaction takes place.  Meanwhile the fuel (which may be gaseous, liquid or solid), in this case fuel oil, is mixed with a solution of sodium chloride in water to form an emulsion or aerosol and passed to the main burner (3) through pipe (6).  Cold air enters through opening (4), passes over cooling tube (17) and absorbs heat and passes through pipe (5) to burners (3) and/or (9).  The reacted quartz is led through chamber (16) to cooling tube (17), evacuated through chute (18) and finely ground. Waste gases pass out through the crude sand feeder 20.  The temperature in the hottest part of the chamber is between 1800 DEG and 2000 DEG C.  The resulting ground quartz powder has a whiteness of 94%.

Abstract: Acid curable aminiplasts are modified by reaction with a diacyl halide of an aliphatic or aromatic carboxylic acid, a disulphonyl halide or a dianhydride of an aromatic acid having at least four carboxyl groups to give a water soluble resin which is self-curing at elevated temperatures.  100 Parts by weight of the resin are modified by 0.3 to 10 parts of the polybasic acid derivative which may be, for example, adipyl, furmaryl, o-, iso- and tere-phthalloyl, octenylsuccinyl, 1,4-benzenedisulphonyl, and 1,3 - naphthalenedisulphonyl chlorides, p,p-dichlorsulphonylbiphenyl and the corresponding fluoro-, bromo- and iodo-derivatives.  The aminoplast and the modifying agent are reacted in the presence of an acid acceptor such as an alkali metal hydroxide or carbonate, tertiary alkyl- or alkanol-amines and anionic exchange resins, and in aqueous solution although the modifying agent may be added dissolved in an organic solvent or in inert microcapsules of gelatine or gum tragacanth.  The modified resins thermoset in the absence of a curing agent but acidic accelerators such as ammonium sulphate, thiocyanate or chloride may be used.  The products are useful as adhesives for wood and in the manufacture of wood particle boards.  In examples flakeboards are prepared from aspen flakes impregnated with the modified aminoplasts of the invention by pressing at 300 DEG  F. at 200 lbs. pressure for 10 minutes.

Title: Method of and apparatus for tuning an aft-controlled electronic tuner to a desired frequency
IPC: H04N5/44
Filed: 1976-11-02
Abstract: 1535860 Tuning section arrangements SONY CORP 2 Nov 1976 [20 Nov 1975] 45567/76 Heading H3Q  In an AFT controlled electronic tuner 100, Fig. 1, when a selected control voltage corresponding to a selected frequency is applied to the tuner, such as when the power supply for the tuner is first energized, AFT control from 120 during the interval that the applied voltage is increasing to its selected value may be such as to vary the voltage from its selected level and in order to properly tune the tuner to the desired frequency the selected control voltage is reapplied automatically at a subsequent predetermined time by a connecting circuit 150. On turning on the tuner a signal derived by means of differentiating circuit 154A, Fig. 7, and a transistor 159 causes a load pulse P B  which transmits the channel identifying code C1-C14 previously stored in a first memory unit of a memory 50 to a counter 40. The output B1-B14 from the counter 40 together with timing signals A1-A14 from a timing counter 20 are applied to a pulse-width modulator 91 which provides a D/A converter 90 supplying the selected tuning voltage to the tuner 100. To override the AFT signal from 120 which includes transistor differential amplifiers (122, 123, Fig. 5, not shown) determining the limits of the AFT action a further load pulse P B  is obtained due to a delayed pulse from the correcting circuit 150 derived from a monostable 156 which ensures that counter 40 and modulator 91 supplies the required tuning voltage to the tuner. The memory has read and write addressing by 70 and 80 for channel selection and reprogramming with coarse and fine initial setting of counter 40 by means of 31 CU/D and 31FU/D switches as in a similar Specification 1,518,712. The AFT output EU and ED control via gates 39 fine up-down adjustment to the counter 40.

GASKELL & CHAMBERS (NON-DRIP-MEASURE) Ltd. 7 Feb., 1967 [7 March, 1966], No. 9882/66. Heading F2V. In a pinch cock, a horizontally extending cylindrical housing 1 has at one end a vertically extending socket 6, through which a flexible tube 7 passes, and houses a piston 8 which is spring- biased towards the tube but movable away from it by a hand lever 16. At the end nearest the tube, the piston has a reduced portion 13 followed by an enlarged portion 12, both these portions serving to anchor a horizontal pressure bar 10 in a way which ensures axial movement of the bar with the plunger whilst allowing the plunger to rotate independently of the bar. The rate of flow through the tube is dependent upon the degree of engagement between the bar and the tube, which in turn is determined by the angular disposition of the handle 16 relative to the piston 8, e.g., with the handle lying perpendicularly to the piston, the latter, and hence the pressure bar, is fully extended towards the tube and so flow through the tube is closed off, whereas when the handle is turned through 90 degrees from this position, the piston and bar are fully retracted and maximum flow through the tube resumed, all intermediate positions of the handle also being possible.
