Title: Apparatus for the electrolytic revivification of ferrocyanide of potassium formed in the purification of gases by oxidation of hydrogen sulphide with ferricyanide of potassium
IPC: C01C3/12
Filed: 1931-07-29
Abstract: 365,983. Electrolytic production of potassium ferricyanide. BRANDT, R., 4, Klaus Grothstrasse, Bergedorf, near Hamburg, Germany. July 29, 1931, No. 21629. Convention date, Dec. 8, 1930. Addition to 319,147, [Class 41, Electrolysis]. [Class 41.] In the process according to the parent Specification for electrolytic reoxidation of potassium ferrocyanide which has been formed by use of the ferricyanide as a purifying agent in gas manufacture, a cell of filter-press form is employed which is built up from bipolar electrodes of an alloy of iron with chromium and nickel such as V2A metal. The formation of detrimental coatings on the electrodes is thereby prevented even when revivifying washing liquors which have been employed for purifying gases such as water gas which contain very little hydrocyanic acid. The cell shown is built up of endplates S<1>, S<2>, electrodes 10 and rubber separators G. Electrolyte passes from distributing pockets T<1>, T<2> through passages O alternately at the top and bottom of the electrodes to a central chamber M and leaves by a pipe 15. Hydrogen passes through passages O<1> to a pipe 16. The central electrodes 6, 7 are connected together. The electrodes may be ribbed. The entering electrolyte must contain some ferricyanide and some bicarbonate for conversion of the alkali which is formed into carbonate.

Abstract: 295,022. Vereinigte Stahlwerke Akt.- Ges. Aug. 6, 1927, [Convention date]. Purifying and refining.-A process for the manufacture of iron and steel which by means of working and suitable heat treatment is transformed into a workable material which is non- sensitive to cold brittleness &c., is characterized by the fact that a charge as free as possible from oxygen is first fused as quickly as possible, easily oxidizable substances such as manganese or silicon being added to prevent oxidation of the bath and to remove sulphur &c. and that during the rest of the smelting process the bath is kept as free as possible from oxygen and oxygen compounds by stage by stage deoxidation by continuously stronger acting deoxidation mediums. The process is carried out in basic hearth furnaces, the charge consists of iron as poor as possible in oxygen, e.g. iron free of rust or chippings freed from rust, and the purifying materials are manganese, silicon, and titanium, used in this order, being added to the bath before the slag extraction. The purification may be carried out in the same furnace or in separate furnaces. The hearth furnaces may be of the type described in German Specifications 333,402 and 349,102.

Abstract: 697,936. Road-laying machines. BLAW-KNOX CO. Sept. 18, 1951 [Sept. 25, 1950]. No. 21859/51. Class 107 A road construction vehicle has runners 11 between which the plastic construction material is confined. The material is deposited from a hopper 15 under a streamlined throat-plate 38 which is continued rearwardly of the machine to gauge the depth of the slab laid. A chassis 76, carried on wheels or other traction surfaces 77, 78, is driven by an engine 105 and steered by the wheel 85a and tows the runner and hopper assembly by chains 102. A centring bar (not shown) connects the front steering bar housing with the hopper to keep the runner assembly centred within the wheels 77, 78. Two hydraulic jacks 129 in front of, and one (not shown) at the rear centre of, the hopper, act to lift. the runner and hopper assembly when the machine is in transit. Electrically driven vibrators are disposed at the exit to the hopper and are supplied by a motor generator set on the chassis. A belting device comprising an electrically driven reciprocating transversely extending stretched belt 57 is carried between the runners 11. The machine may lay level or cambered strips and one or more lanes at a time. Further strips may be laid adjacent to the the existing ones and the road material which oozes out beneath the runners 11 fills up depressions in the sub-grade and provides a level track to guide the runner when laying adjacent strips. The apparatus may be loaded with weights to control the lateral extension of the road material. The hopper is charged by conventional cement mixers. When more than one traffic lane is laid simultaneously a groove may be formed in the road to accommodate coloured marking materials. The spaces between slabs may be filled so as to act as expansion joints or traffic lines.

Locks, permutation.-In a permutation lock, shown applied to the steering-post of a motor car or cycle, the locking-bolt can be released by turning it and then moving it longitudinally. The turning movement can only be effected when the combination rings are set for opening the lock. When the bolt 6 is pushed in to lock the steering- post 2, a spring ward 28 snaps into a locking- notch in the side of a fixed guide-slot 18, release being effected by a projection 39 on the operating- boss 26. To prevent rotation of the bolt to release the ward 28, when the combination rings 14 are not set for release, an eccentric 40 is mounted on the bolt to operate a follower 41. This follower can reciprocate only when slots in the combination rings are in line with a projection 43 on the follower which otherwise prevents rotation of the bolt. Picking, preventing.-Toggle-links 49 pivoted to the follower are operated by movement of the bolt to lock the combination rings against movement while the bolt is being moved.

Abstract: 923,234. Prestressed concrete. A. BRANDESTINI. July 1, 1959 [July 5, 1958; May 26, 1959 (2)], No. 22620/59. Class 20 (4). A bundle of prestressing wires 1 passing through a duct in a concrete construction 6 has its ends located in a terminal recess 5 of the concrete construction where they are engaged with an anchor body 3 which is then drawn from the recess to tension the wires and supported against the end face of the concrete to enable the drawing means 8 to be removed, subsequently to which mortar is introduced into the recess 5 and allowed to harden whereby to anchor the wires 1 and to permit removal of the anchor body 3. In one embodiment the anchor body 3 is provided with a screw-threaded bore which serves for attachment thereto of the drawing means 8 and for introduction of the mortar into the recess 5, and has a plurality of perforations for receiving the wires 1 which are anchored thereto by small heads 4 formed at their ends and which are subsequently wholly or partly ground away to enable the anchor body 3 to be removed from the wires. The external surface of the body 3 is screwthreaded to receive a nut 9 by means of which it is supported against a washer 10 bearing on the end face of the concrete. To increase the adhesion of the wires in the mortar in the recess 5 the wires may be stranded, Fig. 11 (not shown), or may be given a changing crosssection as in Figs. 8 and 9. In other arrangements to increase the adhesion the wires emerging from the duct 2 are spread apart, Fig. 2, or are alternately spread apart and restricted by means of perforated plates 16 and lacings 17, Fig. 6. In another arrangement, small heads provided on the wires in the recess 5 are arranged to abut against auxiliary perforated anchor plates, Fig. 7 (not shown).
