Patent GB-868317-A (GB)
Title: Improvements in or relating to magnetic recording devices
Inventor: BALL ARNOLD GEORGE
IPC: G11B5/02
Filed: 1958-05-07
Abstract: 868,317. Magnetic recording apparatus. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. April 15, 1959 [May 7, 1958], No. 14636/58. Class 40 (2). [Also in Group XIX] A supervisory arrangement for a magnetic drum-type recorder of multi-track type gives an alarm if the output from any record track becomes unsatisfactory. A transformer TR feeds equal out-of-phase waveforms to the " AND " gates MR1, MR2 and MR3, MR4. In-phase pulses TS1 are fed to these gates and the outputs are fed to the " OR " gate MR5, MR6. Whatever the waveform of the input from the drum, the output from the " OR " gate will consist either of equal high-amplitude pulses corresponding to satisfactory reading of the record or of lower amplitude pulses corresponding to unsatisfactory readings. This arrangement is duplicated for each record track being read, the output of the " OR " gates being fed to an " AND " gate comprising rectifiers such as MR7 to the point X, where the low-amplitude pulses are eliminated by bias applied at DL and only those corresponding to a satisfactory reading are amplified at A and fed to the toggle MA. An interlaced set of pulses TS2 either reset the toggle MA after the receipt of the pulses from A or, in the absence of a suitable pulse from A, operate a second toggle MB to operate the alarm. A simplified arrangement (Fig. 2, not shown), eliminates the earlier " AND " gates and feeds the TS1 pulses in at the point X.

Title: A process for the production of ammonia or ammonium salts, soda, caustic soda and tar or oil from common salt and coal
IPC: C01C3/00
Filed: 1931-05-19
Abstract: Sodium carbonate or hydroxide are obtained by a combination of the following steps: (1) coal, especially lignite, is subject to low temperature carbonization, yielding carbon dioxide together with tar and oil products; (2) sodium chloride is reacted with carbon dioxide from step (1) by the ammonia soda process to produce sodium bicarbonate; (3) the sodium bicarbonate from step (2) in admixture with the carbonaceous residue from step (1) is reacted with nitrogen at a high temperature to produce sodium cyanide; (4) the sodium cyanide is hydrolysed to produce sodium carbonate or hydroxide and ammonia.  Ammonium bicarbonate may be obtained by reacting the ammonia with a portion of the carbon-dioxide from step (1), or ammonium chloride may be obtained by reacting the ammonia with the liquor from step (2).  The combustible gases and excess carbonaceous material produced in the carbonization step may be utilized to supply the heat requirements of the process.  The production of ammonia may be increased be returning the alkali product for repeated cyanidization and hydrolysis.  Specifications 347,426 and 348,482 are referred to.  The Specification as open to inspection under Sect. 91 (3) (a) describes also the production of carbon dioxide by the hydrogenation of coal.  It also refers to the production of sodium nitrate by the action of oxygen or air on sodium cyanide.  This subject-matter does not appear in the Specification as accepted.

Filed: 1934-01-23
Abstract: Disinfectants are prepared by dissolving xylenol, halogenated xylenol or a mixture of xylenols and/or halogenated xylenols in an alcohol and mixing this solution with an aqueous solution of saponinum.  In the case of raw xylenol, e.g. crude tar oil fractions corresponding to xylenol, the alcohol may be replaced by an acid such as diluted sulphuric acid.  According to one example 1 : 3 : 5 xylenol and 5-hydroxy-1 : 3-dimethyl-2-chlorobenzene are dissolved in methyl alcohol and the solution is added to an aqueous solution of saponinum with stirring.  The resulting solution may be diluted with water before use.  Essential oils may be added to the mixtures.  The Specification as open to inspection under Sect. 91 comprises also the production of disinfectants by mixing a mixture or solution of xylenol, halogenated xylenol or of a mixture of xylenols and/or halogenated xylenols with an aqueous solution of saponinum.

Air under pressure is fed through ducts C, open at the inner end, at either side of a travelling grate, baffles E directing the air towards the outer end of the space between the runs of the grate, which is closed by a plate E<SP>1</SP>. Plates b<SP>1</SP>, b<SP>2</SP> restrict the passage of air through the grate at each end, and the sloping inner walls d<SP>3</SP> of the air ducts C direct ashes falling through the upper run on to the lower run, and improve the distribution of air transversely of the grate. Since the outer end of the space between the grate runs is closed, the static air pressure increases from the inner end of the grate to the outer end.

Title: A process for the manufacture of alkene trithiocarbonates
IPC: C07D339/06
Filed: 1937-05-29
Abstract: To manufacture alkene trithiocarbonates, suitable for refractometry, for use in the rubber industry or as fungicides or insecticides, carbon disulphide is reacted with an alkene glycol, an alkene glycol ester, or an alkene oxide, and an alkaline substance or with an alkene glycolate.  The reaction may be performed in presence of water or another reaction medium.  In examples ethene trithiocarbonate is prepared from: (1) potassium hydroxide or slaked lime, carbon disulphide, ethene dichloride and water; (2) carbon disulphide and ethylene chlorhydrin in the presence of sodium sec. decyl alcoholate, toluene and benzene; (3) aqueous potassium hydroxide, ethylene chlorhydrin and carbon disulphide; (4) potassium hydroxide, ethene oxide, carbon disulphide and water; (5) sodium glycolate and carbon disulphide; (6) potassium thiocyanate, water, ethene oxide and carbon disulphide.  Ethene sulphide may be formed intermediately and it is stated that ethene sulphide refluxed with carbon disulphide in presence of alkali yields ethene trithiocarbonate; (7) aqueous potassium hydroxide, glycol monoacetate and carbon disulphide. Propene trithiocarbonate is prepared from carbon disulphide and propene dichloride in presence of aqueous potassium hydroxide.ALSO:Alkine trithiocarbonates are useful, in view of their high sulphur content and because they can still dissolve much elementary sulphur, in the rubber industry.

Title: Manufacture of phenol
IPC: C07C37/00
Filed: 1949-06-03
Abstract: In a process for the production of phenol by the decomposition of isopropylbenzene peroxides with acidic catalysts, the yield of phenol is increased by heat decomposition of the material in the peroxide decomposition mixture which boils above the boiling-point of phenol and acetophenone to give phenol and some a -methylstyrene.  The decomposition may be promoted, e.g. by acid.  The high-boiling starting-material, mainly cumylphenol, is obtained by first distilling off acetone, a -methylstyrene, phenol and acetophenone from the reaction mixture resulting from the peroxide decomposition. Four examples of the process are given.  Specifications 610,293, 626,095, 629,429 and 649,286 are referred to.

Hollow metal casings with one end open are made by deforming a billet 17 in a container 1 by a plunger 7 to form firstly a rough casing shape by backward extrusion and then by continued movement of the plunger to thin down the wall of the rough casing by simultaneous extrusion in both. the forward and backward directions. The plunger 7 is secured to a ram 8 and has a conical nose 12 which partially pierces the billet, whilst it is supported in the part conical bore 5 of the container against a backing plunger 13 carried by an upper ram 14, and also effects backward extrusion. The plunger 13 is then withdrawn and the plunger 7 moves upwardly to effect simultaneous forward and backward extrusion of the billet and so produce the conical part 20, Fig. 6 (not shown). The plunger 7 is then withdrawn and the plunger 13 is moved downwardly to eject the finished part. An electric heating system 18 surrounds the container.
