Filed: 1955-12-29
Abstract: The multi-stage continuous process of the parent Specification for preparing hydrocarbon drying oils by polymerizing 50 to 100 parts of butadiene or its homologues with 0 to 50 parts of styrene or its ring alkylated homologues in the presence of inert hydrocarbon diluents, ether modifiers, alkali metal catalysts and activators, is modified in that the equilibrium concentration of monomers in the 1st stage is between 40 and 60 per cent on a diluent-free basis.  Specified diluents are naphtha, Varsol, butane, pentane, benzene, toluene, xylene, cyclohexane, butenes and pentenes.  Specified modifiers are dioxane-1,4, diethyl ether and vinyl isobutyl ether.  Specified catalysts are sodium, potassium, lithium, caesium and rubidium. Specified activators are ethanol, isopropanol, isobutanol, isopentanol, secondary butanol and tertiary butanol.  The high concentration of monomers in the 1st stage may be obtained by using low catalyst concentrations, short residence times and small quantities of diluent.  Additional diluent, styrene, modifier and catalyst may be added to succeeding stages.  Catalyst may be removed from the product by adding excess glacial acetic acid, neutralizing with ammonia and filtering.  Excess diluent, modifier and activator may be stripped off and recycled.

Title: Improvements in refrigerating system including auxiliary hot gas defrosting circuit
IPC: F25B47/02
Filed: 1958-11-21
Abstract: 895,227. Refrigerating. GENERAL ELECTRIC CO. Nov. 21, 1958 [Nov. 25, 1957], No. 37552/58. Class 29. To defrost the evaporator 6 of a compression system, a hot gas conduit 23 from the high pressure side is led in heat exchange relation with the evaporator and condensing pressure is maintained in the conduit 23 by a restrictor 25. The compressor 11 and its motor 10 are disposed in a sealed casing 12 under suction pressure and acting as a lubricant reservoir. Compressed refrigerant flows through pipe 16, condenser 2 and capillary restrictor 3 to the evaporator 6 which terminates in an accumulator 7 from which suction pipe 5 leads to the casing 12, pipe 5 being in heat exchange relation at 8 with the capillary restrictor 3. To defrost a valve 20 is opened and hot gas flows through pipe 18 to a conduit 22 in heat exchange with accumulator 7 and then to conduit 23. Liquid refrigerant formed in conduits 22, 23 flows through restrictor 25 to suction pipe 5 and thence into case 12 where it is evaporated by the heat of the compressor and motor. As shown, valve 20 is controlled by a unit 34 which initiates defrosting, e.g. by a timer and terminates it when the evaporator temperature, detected by thermal bulb 35, rises sufficiently. Condenser fan 37 is energised in phase with the closing of valve 20 and the control is such that defrosting will only be initiated when the compressor motor is energized. As shown the evaporator is a rollbonded structure with the conduits 22, 23 formed therein but the conduits may be brazed to-the evaporator; alternatively the evaporator and the conduits may be constituted by a double-tube extrusion. To reduce the speed of defrosting, the conduits 22, 23 and the evaporator may be so disposed that the hot gas heats first the inlet end of the evaporator and last the accumulator and the hot gas may flow from the outlet of the condenser instead of from the compressor outlet.

Abstract: 831,172. Mangles. BJORCK, C. T. B. Dec. 3, 1957 [Dec. 4, 1956], No. 37606/57. Class 138 (2). A mangle with at least two rollers one of which (3) is driven by an electric motor has a manually operated protective member (gate 29) in front of the rollers connected to a cut-out and reversing switch in the motor circuit, so that the member controls the starting, stopping and reversing of the motor and the rollers. As shown, rollers 4, 5 rotatably mounted in slidable bearings 7 are each held against roller 3 by two springs 6 connected to the bearings 7 and to the stationary bearings 9 of roller 3. A mangle board 18 is hinged to stays 19, has holes to engage over two pins 28 on the top of a fixed girder 17, and is fitted with carriers 22 for a hinged shield 23 the U-shaped lower edge of which is engageable with the bent edge of a hinged plate 24. The shield 23, plate 24 and a fixed inclined shield 26 form a chamber for collecting mangled garments. There is a fixed gate 33 above the gate 29, the latter operating the switch (31, not shown) through one of its bearings 30. Preferably the switch is so arranged that the motor is driven in the direction of mangling when the gate 29 is vertically downward, is stopped when the gate is moved from the vertical, and is reversed when the gate is vertically upward. An overload of garments depresses the lower bearings 7, one of which then engages an adjustable feeler 38 on a second switch 36 which opens the circuit. The mangle may be illuminated by a tubular lamp 34 behind a shade 35.

Abstract: 1,162,930. Discharging particulate material from containers. METALLGESELLSCHAFT A.G. 7 Aug., 1968 [29 Aug., 1967], No. 37737/68. Heading B8A. A discharge pipe 2 fitted to the discharge opening of a container 1, which is under subatmospheric pressure, is provided with a pipe segment 4 having a forwardly inclined parabolic edge and is sealed by a rubber flap 3. The material to be discharged accumulates in the pipe 2 above the flap 3 until the accumulated material lifts the flap from the edge of the discharge pipe 2 at B. A subatmospheric pressure is thereby created in the gap between the pipe 2 and the pipe segment 4 and causes the flap to seal against the pipe segment 4 at the point A. Material then trickles into the gap until the force of the accumulated material lifts the flap from the point A allowing the material to discharge on to a belt conveyer 5. When the flap is lifted from the point A, it is forced back against the discharge pipe at the point B so that the cycle can be repeated. Bleed holes 6 may be provided in the pipe segment 4 to allow air to enter the space between the pipe segment and the flap 3 and thereby to allow the flap to lift more often adjacent the point A than adjacent the point B.
