Title: Improvements in or relating to magnetic records
Inventor: ANGOLD EDWARD BARNABAS
IPC: G11B5/84
Filed: 1954-10-20
Abstract: 786,891. Coating webs. THERMIONIC PRODUCTS, Ltd. Nov. 30, 1955 [Oct. 20, 1954], No. 30260/54. Addition to 759,486. Class 140. [Also in Group XXXV] A high glaze or gloss is imparted to the operative surface of a magnetic recording medium supported on a flexible backing by applying to the operative surface a non-metallic flexible strip, e.g. regenerated cellulose film, having an optically smooth surface in engagement with the operative surface, subjecting the engaging surfaces to heat and pressure, cooling, and stripping off the flexible medium. The apparatus described in the parent Specification is modified by providing additional stock and take-up reels for the flexible material. A single tape or more than two tapes may be treated by providing the requisite number of stock and take-up reels.

Title: Improved process for producing a permanent flexibility of wood, and a machine for use in carrying out the said process
IPC: B27K5/00
Filed: 1932-10-28
Abstract: 409,347. Making wood flexible. ANDERSEN, S. A., 30, Vestergade, Middelfart, Denmark. Oct, 28, 1932, No. 30280. Convention date, Sept. 12. [Classes 145 (i) and 145 (ii).] In a process for rendering wood permanently flexible by subjecting it to longitudinal compression while in temporarily flexible condition, the wood is subjected to bending during the compression. Pressures 2, Fig. 1, are applied to the ends of the wood 1 which has been steamed or otherwise rendered temporarily flexible, the wood assuming a curved shape ; a pressure 3 is then applied to its side to straighten it, resulting in a longitudinal compression. The end abutment members are then moved inwardly, and the process repeated a number of times. The wood may be bent past the rectilinear position to the concave position and again straightened. The wood may be bent into wave form, as shown in Fig. 3, by means of pressures 3, 7. A machine for carrying out the process, Fig. 4, comprises pistons 13 driven by a cam shaft 11 ; the wood is placed between two spring bands 18 which assist in distributing the pressure, and is subjected to pressure on its ends by adjustable pistons 16 ; the tightening of the latter may be effected automatically by the cam shaft 11. After compression the wood is dried by heating.

Title: Improvements in or relating to isomerization process
IPC: C07C5/27
Filed: 1954-10-21
Abstract: An isomerization process comprises contacting, under substantially anhydrous conditions and in the substantial absence of reactive hydrocarbons a secondary alkyltoluene selected from the class of (a) the ortho isomer; (b) the para isomer; (c) a mixture of para and ortho isomers; (d) a mixture of the ortho isomer and/or para isomer with the meta isomer of isopropyl toluene and secondary butyl toluene with at least 1 mol. of BF3 per mol. of secondary alkyltoluene charged and at least sufficient liquid HF to form a distinct acid phase, at a temperature of not more than - 20 DEG  C. for a time of not more than 30 minutes wherein the lower the temperature of contacting, the longer the permissible time of contacting, and removing HF and BF3 from said acid phase under conditions substantially to avoid rearrangement reactions and recovering from the reaction product a secondary alkyltoluene fraction comprising substantially the meta isomer.  Preferably the isomerization is carried out in the presence of at least 1 added mol. of toluene. Non-reactive hydrocarbons which may be used include isopentane, butane and pentane.  In a typical example, para cymene, commercial grade anhydrous liquid HF and commercial BF3 were agitated in a carbon steel reactor for 30 minutes at - 20 DEG  C.  The reaction product contained about 6 mol. per cent of 3,5-di-isopropyltoluene.

The adsorbent: adsorbate ratio may be between 1 : 0.1 and 1 : 10. The adsorbate may be formed in situ by reaction of the dissolved compound with a water soluble hydroxide, acid or salt. Water may be added as a precipitant and the liquid in which the carbon is suspended is preferably miscible with water. Specified adsorbates are Al(NO 3 ) 3 , MgSO 4 , CoCl 3 , SnCl 2 , BiOCl 3 , MnCl, AgCl, (C 6 H 5 ) 3 SnCl and (C 6 H 5 ) 3 SnOH.

Abstract: 1436644 Agglomeration of minerals on a circular grate CREUSOT-LOIRE ENTREPRISES 10 July 1974 [30 Aug 1973] 30633/74 Heading F4B An installation for agglomeration of minerals has a circular grate comprising a succession of grate-carrier ears 20 supported by wheels 21/22 on two circular power driven co-axial tracks 24/25. The tracks move the cars in the direction 1 through a zone 2 for loading from a conveyer 3, an ignition zone 4, a baking zone 5, a cooling zone 10 and finally to a discharge zone 16. At zone 16 an overhead control car 45, with arms operated by jacks 52 and 53, locks on to projections 58 of the front axle of each individual car 20 on arrival at the zone. A jack 48 moves the control car 45 on the track 47 at a speed higher than the linear speed of the track 24/25, and then separates a car 20 from the next succeeding car. Jacks 53 are then retracted and the agglomerate slides into the hopper 55. The car 20 is then lowered by jacks 53 and continues to move forward under the force of jack 48 along the track 24/25 until it contacts the car previously emptied. Jacks 52 then release the car 20 and the control car 45 returns in order to empty the next car. In a modified embodiment the cars 20 may be separated and emptied by the successive operation of three jack assemblies pivoted on a beam (66), Figs. 6 and 7 (not shown), either side of the grate.
Patent GB-498734-A (GB)
Title: Improvements in and relating to methods and means for the treatment of gases
IPC: C10K1/32
Filed: 1937-06-07
Abstract: Hydrogen sulphide and like substances are removed from gases, e.g. coal gas, by subjecting them to the action of active carbon with which is associated iron oxide and/or hydroxide.  The hydrogen sulphide and the like is adsorbed by the carbon and reacts with the iron oxide.  A suitable catalyst is obtained by saturating a porous active carbon with an iron compound, e.g. ferrous sulphate and then precipitating ferrous hydroxide in situ. If desired the material may be heated to dehydrate the hydroxide, at least in part.  The carbon may be regenerated by washing out soluble compounds, reactivating and reimpregnating, or by heating.  The material may adsorb up to 10 per cent of hydrogen sulphide by weight.

Title: Improvements in or relating to the manufacture of alkali metal carbonates
IPC: C01D7/12
Filed: 1954-10-29
Abstract: An alkali metal carbonate, of intermediate bulk density and particle size, is produced by calcining a mixture of hydrated alkali metal carbonate and alkali metal bicarbonate and of composition in terms of sodium carbonate equivalents within the range 1:1 to 1:1:6.  The mixture is calcined at a temperature above that at which the decomposition of the bicarbonate begins and at which the hydrated carbonate becomes anhydrous.  Anhydrous alkali metal carbonate or a portion of previously calcined product may be added to the mixture before calcination. Sufficient water may be added to the mixture before calcination of bicarbonate and carbonate to form the hydrate of the carbonate. The alkali metal may be sodium and may be associated with an ammonium salt, e.g. ammonium carbonate which may be from the ammonia-soda process in which case calcination is at 100 DEG -250 DEG C. If sodium carbonate is used the salt may be anhydrous and sufficient water to form the monohydrate is added.

A table showing the connections of the registers, which comprise transistorized flip-flop circuits, to the gates is given and examples indicate the possible responses produced by failure of one of the flip-flops e.g. if the least significant flip-flop T01 in OR register fails to set i.e. records a ' 1 ' in its inverse position then for a data input equivalent to decimals 1, 3, 5, 7 two gates will open for each code, gates G0, G1 or G2, G3 or G4, G5 or G6, G7 respectively. For numbers 9, 11, 13, 15 no gates will be opened. All other numbers (for a four bit register) correspond to no fault condition since T01 would in those cases be already re-set.
