Abstract: 1,176,646. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 6 April, 1967 [6 April, 1966], No. 15436/66. Heading G6C. In a nuclear fast reactor, the vertical fuel elements are each supported on a mounting fixed to a diagrid plate. The mounting incorporates two pieces of dissimilar metal which have different coefficients of thermal expansion and which produce and lateral displacement of the fuel elements during temperature changes. A core temperature increase thus reduces reactivity.

Abstract: 256,192. Urbana, Coke Corporation, (Assignees of Parr, S. W., and Layng, T. E.). July 30, 1925, [Convention date]. Retort furnaces; charging.-Fuel such as coal is preheated uniformly nearly up to the temperature at which hydrocarbon vapours are evolved and the mass becomes pasty and the preheated product is then subjected to sufficient heat to complete the coking operation. The coal, preferably finely ground, is fed from a hopper 17 into a cylinder 15 through which it is passed by a worm conveyer 19 and is discharged into a container 5 communicating with vertical retorts 2. Conduits 11 - - 14 convey the hot flue gases from the vertical retort setting to the space around the cylinder 15 which is also heated by a burner 16.

Abstract: 567,277. Electromagnetic switches. BRAIN, H. E., and AUTOMATIC TELEGRAPH & RADIO TRANSCEIVER CO.,.Ltd. Sept. 23, 1943, No. 15626. [Class 38 (v)] In an electromagnetic switch adapted to open contacts 12 a short time after the deenergization of a magnet 1, a lever 3, operated by the armature 2, has pivoted to it a member consisting of a tooth 7 and a cam 8, the tooth being adapted to engage frictionally a driven disc 5 and the flat surfaces of the cam being adapted to co-operate with two fixed flat stops 11. When the magnet is de-energized, the armature and lever 3 move up a short distance without disengagement of the spring contacts 12, till the tooth 7 engages the disc 5. The tooth is then driven by the disc so that eventually the lever 3 can move still further upward till a flat portion of the cam engages the flat upper stop 11 and the contacts 12 separate. The electromagnet, the contacts 12 and the motor driving the disc 5 may all be in one circuit.
Patent GB-562584-A (GB)
Title: Water-soluble carboxyethyl cellulose ether
IPC: C08B11/12
Filed: 1942-11-05
Abstract: A water-soluble carboxy ethyl cellulose ether is obtained by reacting cellulose in the temperature range of 5-35 DEG  C. with an aqueous solution containing about 10-40 per cent of a strongly basic water-soluble hydroxide and at least one molecular proportion of acrylonitrile per glucose unit of the cellulose, the amount of hydroxide being at least molecularly equivalent to the acrylonitrile, and the reaction is continued until the reaction mixture is capable of forming a homogeneous solution with water, even when acidified. The initial material may be cotton, regenerated cellulose, cellulose obtained from wood pulp by removal of lignin and resins, or cellulose obtained from flax or other bast fibres.  The hydroxide may be caustic soda or potash, or a quaternary ammonium hydroxide, such as benzyl trimethyl or dibenzyl dimethyl ammonium hydroxide.  The cellulose in finely divided or fibrous form may be mixed with the hydroxide solution and the acrylonitrile is then added.  The alkali-cellulose may be aged before adding the acrylonitrile.  The carboxyethyl cellulose ether may be isolated by neutralising the reaction mixture with an acid such as acetic, hydrochloric, or sulphuric acid, and precipitating the ether by addition of water-miscible organic liquid, such as methyl or ethyl alcohol or acetone.  The ether need not be isolated, since the neutralised or acidified reaction solution may be used directly for many purposes, e.g. as a thickening agent for printing pastes, coating materials, sizes, and the like, and as a protective colloid for stabilizing emulsions.

Divided out of 430,029. Drawings to Specification. [Class 38 (iii)] Field control ; non-regenerative braking.- The field windings of a vehicle motor are subdivided and speed control is effected by changing the connections of the field sections by means of contactors, the windings of which are connected in circuit with respective field winding sections. A master controller brings each contactor into action by connecting its winding across one or more field sections, and when the contactor operates it throws its winding into series with a field section. The invention is described with reference to the system of control described in Specification 430,029 and in addition there are described arrangements for preventing the operation of the series-parallel transition contactor in the motor circuit when braking is effected with the field sections in series. In one arrangement, Fig. 8 (not shown), the transition contactor is provided with a second opposing winding. Alternatively, the controller may short-circuit or open the circuit of the transition contactor winding.

Abstract: 736,014. Softening and imparting special properties to water. MAIN WATER HEATERS, Ltd. June 24,1953 [June 24, 1952], No. 15905/52. Class 46, In water-softening or scale-reducing devices of the kind in which a container for a charge of suitable chemical is detachably connected to a limb of a T-piece, the other two limbs of which are arranged foi assemblage in a pipe line, a valve is arranged at the junction of the T-piece and means are associated with the container for opening the valve when the container is assembled with the T-piece and means for automatically closing the valve when the container is removed. AT-piece 17, 18, 19 is threaded for connection in a pipe-line and has screwed into it at 17 a container 10. A plate-valve 24 has a resilient washer 25 secured to it by a hub 22 resting loosely on a spindle 14 secured to the base of the container 10, so that when the container is unscrewed from the branch 17 of the T-piece the valve 24 comes to rest, for example with the assistance of a compression spring 26, against a seat 21 provided around an opening 20, and thus prevents escape of water from the pipe-line. By the time that that part of the container neck bearing holes 16 has emerged from the branch 17, during unscrewing of the container, the valve should be seated; if it has not done so, escape of water from the holes 16 indicates the fact. A gauze 9 retained on a shoulder 13 within the casing 10 prevents crystals of the chemical from being.swept bodily into the water stream.

[Classes 120 (iii) and 142 (iv).] High twist crape yarns for the production of crape fabrics have their high twist imparted in two or more stages, a relatively large proportion of the twisting being done preferably in the first or an early stage of the twisting. The sizing may be effected between the stages of twisting and either before or after the twisting. The process is applicable to yarns composed of cellulose acetate or other organic derivatives of cellulose such as the formate, propionate, butyrate or methyl, ethyl or benzyl cellulose, or of reconstituted cellulose such as viscose, nitrocellulose or cuprammonium - silk, or of natural silk, all either as continuous filaments or as spun yarn and also of natural fibres such as cotton, wool or of mixture yarns, or doubled yarns containing the same or different filaments or fibres. The highly twisted crape yarns so obtained may be incorporated in fabrics as warp or weft either alone or alternating with ordinary yarns. Yarns having left and right-hand twist may be alternated. In an example described, cellulose acetate yarn of 140-160 denier receives first 40-50 turns per inch and afterwards a further 10, 20 or 30 turns per inch and between the two stages is sized with starch size or gelatine solution to which a softening agent such as glycerine or castor oil may be added. Algin or the other sizes described in Specifications 348,589, 352,541, and 357,169 may be used. Specifications 351,999, 352,000, 356,233, and 357,084 are also referred to.
