Abstract: 367,465. Cooking ranges. WRIGHT & EAGLE RANGE, Ltd., J., Essex Works, Thimble Mill Lane, Aston, and ACHURCH, G. P., 49, Broad Street, both in Birmingham. Aug. 13, 1931, No. 33348/30.

Patent GB-820316-A (GB)
Title: Apparatus for controlling the temperature of air within a compartment
IPC: B64D13/00
Filed: 1955-11-22
Abstract: 820,316. Automatic temperature-control systems. UNITED AIRCRAFT CORPORATION. Nov. 22, 1955 [Nov. 26, 1954], No. 33386/55. Class 38 (4). In a system for automatically controlling the temperature of air within an enclosure in which the relative proportions of a mixture of heated and cooled air supplied to the enclosure is adjusted in proportion to the temperature of air in the enclosure, over-riding control of the mixture in proportion to the rate of change of temperature of the air mixture is provided for limiting purposes. In Fig. 1 air is supplied from a jet engine compressor 10 through a conduit 18 to an aircraft cabin 20. Some of the air passes through a conduit 16 and is cooled in a heat-exchanger 22, while the remainder passes through a conduit 14 and is uncooled. Further cooling of the air passing through conduit 16 is effected by causing it to operate a turbine 26 driving a fan 32 which assists the passage of ram air through heat exchanger 22. A temperature-variable resistor 40, responsive to cabin temperature, is associated with an electronic controller 46 which controls a pneumatic servomotor 234 operating a valve in conduit 14 so as to alter the proportions of cooled and uncooled air to maintain cabin temperature constant. In the electronic controller 46, see also Fig. 2, temperature-variable resistor 40 controls the energization of a solenoid 35 through thermionic valves 102 and 94. A resistancecapacity network 112 provides a response dependent on rate of change of cabin temperature. Solenoid 35 is associated with a permanent magnet 84, Fig. 4, and controls the position of a pivoted spring-balanced armature 69. The position of armature 69 determines the size of an orifice 66 and hence the leakage of air from conduit 14 through a restriction 56, so that a pressure dependent on cabin temperature is set up in a conduit 60 to operate pneumatic servomotor 234 which adjusts the position of the valve, 48, in conduit 14. Follow-up is provided by a cam 86, operated by servomotor 234, acting on armature 69. Increase of the temperature of the air in conduit 18 above a predetermined value is prevented by the effect on a temperature-variable resistor 42, Figs. 1 and 2, in conduit 18, which renders biased rectifiers 132, 134 conductive so that control by resistor 40 is over-ridden and valve 48 in conduit 14 is moved towards a closed position. Similarly decrease of the temperature of the air in conduit 18 below a predetermined value is prevented by a temperature-variable resistor 43 cooperating with a biased rectifier 139 to open valve 48. Rate of rise of temperature in conduit 18 is prevented from exceeding a predetermined value by the combined effect of a temperature-variable resistor 44 and a condenser 122 to close valve 48. A pressureresponsive relief valve 38 maintains cabin pressure constant. Specification 656.208 is referred to.

Abstract: In the alkylation of isobutane, wherein a fresh feed comprising p  a C3-C5 olefine, isobutane in a greater and n-butane in a smaller molar concentration than the olefine is mixed with a recycle fraction to give a reactor feed having at least five mols. of isobutane per mol. of olefine, the reactor feed is reacted in the liquid phase in the presence of sulphuric acid as catalyst and the reactor feed is separated into a hydrocarbon stream and acid, the hydrocarbon stream is introduced as a liquid into the top of a stripping zone from which there are recovered an overhead vapour product containing isobutane and a minor proportion of n-butane and a bottoms liquid product containing alkylated hydrocarbon and n-butane in an amount of at least that introduced in the fresh feed and the isobutane and n-butane in the overhead vapour product are condensed and cooled and form the recycle fraction above.  The total hydrocarbon feed to the reactor preferably contains 5 to 10 mols. of isobutane per mol. of olefine and 3 to 8 mols. per mol. of n-butane.  The sulphuric acid in the reactor should have a titratable acidity of at least 88% and the volumetric ratio of acid to hydrocarbon is preferably 1.2 to 2.3 : 1. A temperature of up to 20 DEG  C., e.g. 5-15 DEG  C. at a pressure of 3.5-17 atmospheres can be used with a hydrocarbon space velocity of 5-15 vol./vol./min.  The liquid reactants are agitated by mixing nozzles, internal stirrers or internal circulation through a mixing pump.  The stripper is preferably operated at a lower pressure than the reactor in the range of 8.5-11 atmospheres. All or part, preferably 5-25 liquid volume per cent, of the stripper overhead may be passed to a depropanizer operated at a pressure of 17-22 atmospheres and in such a manner that not more than 1 per cent of the butanes is lost.  If the fresh feed contains appreciable amounts of C3 hydrocarbons it may be introduced into the system in the depropanizer.

[Class 20 (iv)] A joint between adjacent concrete road slabs consists of two substantially parallel plates, 1, 2, which are spaced apart so as to constitute shuttering to form the joint and have elements on the outside for anchoring them in the concrete slabs. the upper portions of the plates being inwardly and upwardly inclined at a constant gradient throughout their slope and being rigidly united along the upper edges so as to form a roof-shaped portion which is resistant to deformation by vertical forces, but susceptible of deformation by horizontal forces acting at right-angles to the plates. The plates 1, 2 are of the same length as the joint to be formed, and the upper edges' 5 of the plates may be welded together. The upper edges' of the plates areenclosed by upstanding plates 6, 7, which are welded on to the plates 1, 2, and are supported by struts 4 in the form of metal angle-plates serving also to support the anchor rods 3 welded on to the plates 1, 2.

The cooling water is then pumped through a duct to regions remote from the power station, heat being extracted from the water at these regions by means of a heat pump and applied to a heat carrying medium which is then employable as a heating agent. The duct for the cooling water may be disposed under a roadway to keep it free from snow and ice. When there is high demand for electrical energy, the duct may be used as balancing storage to enable the electrical output to be regulated by variation of the condenser pressure. After extraction of heat, the cooling water may be used as utility or drinking water or for dilution and cooling of waste water.
