Abstract: Copolyethers useful as lubricants or plasticizers are prepared by catalytic polymerization at 80-35 mol. per cent. of ethylene oxide with 20-65 mol. per cent. of isobutene and/or 2-butene oxide. Suitable polymerization catalysts are alkaline, e.g. alkali-metal hydroxides or alcoholates or acid, e.g. boron trifluoride, aluminium chloride, sulphuric acid, thio halogen acids, stearic chloride, or p-toluene sulphonic acid.

A reaction initiator, e.g. water, a monohydric alcohol or phenol, ethylene glycol, propylene glycol, diethylene glycol, dipropylene glycol or butylene glycol may be added, and may take the place of the reaction diluent.  The products may be esterified or etherified.  Examples describe copolymers from (1), (4) ethylene oxide and isobutene oxide in presence of butanol; (3) ethylene oxide and isobutene oxide; (5) ethylene oxide and 2-butene oxide in presence of butanol.

[Also in Division B7] A hopper, preferably mounted on a trailer chassis, receives material directly from a discharge lorry and in turn is discharged, e.g. into a spreader, by tipping the hopper towards a discharge conveyer. A hopper 22 is pivoted at 21 on a chassis 10 of a trailer the wheels 15 of which are supported on legs 13 pivoted at 12 on the chassis and operable by rams 16 between an elevated trailing position and a lowered position, in which the trailer is supported by feet 46 on the ground. The front end of the hopper is open except for removable boards so that a lorry can back up ramps, if necessary into the hopper, to tip material directly into it while the front end has sloped plates to direct material to a discharge opening from which it is conveyed by a screw or other elevator 31, to be discharged over a deflector 45 into a spreader 53. For discharging the hopper is tipped towards its discharge end by a ram 42. The rams and screw elevator are controlled by valves 20, 43, 44 controlling the fluid supply from a pump to the rams and an hydraulic motor 33.

Abstract: 1,135,065. Photographic delay mechanisms. PENTACON DRESDEN KAMERA-UND KINOWERKE VEB. Jan. 19, 1966, No.2474/66. Heading G2A. A delayed action mechanism for a photographic camera is shown it its run down position. To cock the mechanism a winding shaft 2 is rotated with the aid of a handle so as to tension a drive spring in a housing 4, which spring drives an escape wheel 5. A control cam 3 is also rotated so that a point 3a thereof engages an aperture 10 in a release slider 7 and then urges the slider upwards, so as to tension a spring 9, until a nose 16 of a blocking slider 12 enters the aperture 11 of the slider 7 and holds it in its cocked position. An intermediate lever 18 which follows the cam 3 is pivoted anti-clockwise as seen. Release operation. By operation of the camera release arrangement a lever 22 is pivoted out of the plane of the Fig., and an oblique surface 26 thereof engages the intermediate lever and pivots it back towards its original position. The lever 18 pivots a bellcrank lever 21 out of contact with an escape lever 6 so that the pre-timer mechanism can run-off under action of the spring in housing 4. The cam 3 is rotated back towards the position shown, and eventually engages a surface 17 of the blocking slider 12 which is thus drawn out of the aperture 11. This frees the release slider 7 and, since the cam 3 has completely restored the lever 18 to the position shown, the release lever 22 is free to be pivoted by the slider 7, drawn downwards (as seen) by the tensioned spring 9. The lever 22 then initiates the exposure.

Title: Hydroxyphenyl Isocyanates and Urea Derivatives prepared therefrom
IPC: C07C265/12
Filed: 1968-01-17
Abstract: 1,153,261. Isocyanates; urea derivatives. UPJOHN CO. 17 Jan., 1968 [27 Jan., 1967], No. 2574/68. Heading C2C. The invention comprises (a) isocyanates of the formula in which the -NCO group is in m- or p-position to the hydroxy group and R 1  denotes 0-4 inert substituents; and (b) the conversion of the isocyanates into urea derivatives of the formula in which R 2  and R 3  are hydrogen atoms or hydrocarbon groups, which may be substituted. Many specific examples of R 1 , R 2  and R 3  are given. The isocyanates are obtainable by reacting an appropriate aminophenol with phosgene in the presence of an aprotic polar organic solvent having a dielectric constant of at least 2, a number of which are specified. The isocyanates may then be converted directly into the urea derivatives or they may be isolated and purified. A described purification process comprises heating the isocyanates to about 50- 100 C., whereby a solid insoluble polymer is formed from which monomeric impurities may be removed by trituration with solvents; the isocyanates are then regenerated from the polymers by heating the latter to 200 C. or above under reduced pressure. Reaction (b) may be effected at 0-100 C., optionally in the presence of a solvent which may (but need not) be an aprotic polar solvent. Examples are given of the manufacture of m- and p-isocyanatophenol, 2,6 - dichloro - 4 - isocyanatophenol, 1 - (4 - hydroxyphenyl) - 3 - isopropyl urea, 1 - (3 - hydroxyphenyl) - 3,3 - dimethyl urea and 1 - (3 - hydroxyphenyl) - 3,3 - diethyl urea. Many other products of the invention are specified. The urea derivatives are useful, e.g., in the manufacture of ureidophenyl carbamates for herbicidal use.

The product is purified by distillation in a stream of carbon dioxide.  In a modification drying or semi-drying oils may be added before or after the interpolymerization and esters may be prepared by reacting the interpolymers with polyhydric alcohol or a partial ester of polyhydric alcohol and a drying or semi-drying oil fatty acid.

Abutments 6 on the girders receive a locking wedge 7. The arrangement is such that the girder with the head 4 can fall freely out of the members 3, 5 on removal of the locking wedge 7 and associated prop. The extension 2 is formed with shoulders 9 which, in the event of sagging at the point of connection, bear downwardly on the flanges 5 and maintain the connection. The head 4 is formed with bevels 10 to permit ease of rotational movement. In a modification the hook-like flanges are formed on the extension 2 and engage lateral extensions on the cheeks at the ends of an adjacent girder.

Abstract: 1453132 Automatic voltage and current regulation MOTOROLA Inc 22 Jan 1974 [19 March 1973] 02865/74 Headings G3R and G3X [Also in Division H3]  An oscillator circuit includes cross-coupled transistors with a frequency-determining device connected between respective electrodes. A control signal is formed by sensing the amplitude of oscillation and is used to vary the current in a portion of the oscillator so as to regulate the amplitude. As shown, an integrated circuit oscillator 10 comprises transistors 16, 18 cross-coupled through transistors 12, 14. A Piezo-electric crystal 20 and variable capacitor 22 are connected between the emitters of transistors 16, 18. The oscillator output is fed to transistors 52, 54 which supply output terminals 70, 72 and are also connected to a detector and rectifier circuit 59. The voltage developed across a capacitor 64 controls the current flowing in transistors 32, 34 which are connected as by-pass circuits for transistors 16, 18. The transistors 32, 34 are connected with further transistors 28, 30 to form differential amplifiers  which are fed by constant current sources 24, 26 respectively, so that any increase in current in transistors 32, 34 is accompanied by a corresponding decrease in current through transistors 28, 30 and vice versa, so that the current flowing in the oscillator is adjusted in order to vary the gain and regulate the output. Appropriate constant current and voltage supplies for the oscillator, detector and amplifier circuits are provided by a bias network 39. The circuit parameters are chosen such that the transistors 32, 34 shunt sufficient current to ensure that the oscillator operates in a linear region and provides a sinusoidal output.
