Abstract: 1385369 Blow-moulding MONSANTO CO 5 May 1972 [6 May 1971] 20984/72 Heading B5A A blow-moulding machine has at least one of the mould sections formed with a bore opening into the cavity and a needle assembly comprising a hollow needle so mounted in the bore as to be movable into and out of the cavity and extractable from the bore when the mould is open. As shown in Fig. 2, mould 10 comprises sections 11, 12 defining cavity 13. A bore 26 leading into cavity 13 contains a piston 36 carrying needle 14 and movable against stop member 30. Piston 36 and rod 41 are screwed together, holding flared portion 45 of needle 14 therebetween. Blowing air is supplied through duct (46, Fig. 1, not shown) leading into bore 26 and then through ducts 62, 43 into cavity 13, moving piston 36 forward thereby. Air is prevented from entering duct 62 until the parison is punctured by means of recess 58 which houses end 60 of rod 41 until piston 36 is sufficiently advanced. Piston 36 is retracted by air supplied through ducts 50, 48 and channels 40, 38 in stop member 30 and surface 72 of piston 36. In an alternative embodiment (Fig. 3, not shown), needle 14 opens (at 57) into bore 26, blowing air being cut off until portion (57) clears stopper (48) as piston 36 is advanced.

IPC: C05D1/00
Filed: 1965-05-18
Abstract: Finely-divided granular potash containing salt ore, e.g. less than - 48 mesh, is agglomerated, e.g. for fertilizer application, by wetting the fines with an aqueous solution containing hydrofluoric acid or a metal fluoride, forming the wetted particles into aggregates, e.g. in a pelletizing drum or on a pelletizing disc or balling drum, and hardening the aggregates by drying at an elevated temperature below the fusion temperature, e.g. 200 DEG  to 650 DEG  C.  The hydrofluoric acid or metal fluoride solution may be applied prior to, during or subsequent to pelletizing and the preferred solution contains about 10% by weight of the fluoride compound which is used in a ratio by weight to the granular material of about 2:100.  The pellets are preferably agitated during the drying process.

Abstract: 740,543. Transformers and inductors. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 4, 1953 [Aug. 25, 1952], No. 21285/52. Class 38 (2). A method of winding a toroidal coil comprises forming a toroidal path of a conductive material such as colloidal graphite and electrolytically depositing on this path a conducting material such as copper so as to form a conductor of the required cross-section. The conductor may have a uniform cross-section, the axial, radial, and cir. cumferential dimensions at varying positions in the coil being arranged to produce such a cross-section (see Fig. 4). The former on which the coil is formed may be of a liquefiable substance in order to be removable after formation of the coil. In a transformer formed by such a process the windings may be superimposed on, or interleaved with, one another.

Title: Improvements in and relating to a process for the purification of xylenes by distillaion
IPC: C07C7/06
Filed: 1948-08-13
Abstract: Non-aromatic hydrocarbons are separated from admixture with xylenes, ethyl benzene and styrene by distilling the mixture in the presence of 2-dimethylaminoethanol, whereby the non-aromatic hydrocarbons are preferentially volatilized in the form of their azeotropes with 2-dimethylaminoethanol.  The latter may be recovered for re-use in a subsequent distillation by adding water to the distillate, which is homogeneous, preferably with cooling whereby an aqueous solution of 2-dimethylaminoethanol separates out as a lower layer which is withdrawn and dehydrated.  In an example, a cracked petrol fraction boiling within the range 130-145 DEG  C. and containing 54 per cent xylenes was mixed with about half its volume of 2-dimethylaminoethanol; and the mixture was distilled using a distillation column packed with Raschig rings (equivalent to 15 theoretical plates) operated at a reflux ratio of 9 : 1.  The distillation was stopped when the temperature in the boiler reached 132.5 DEG  C.  The residue in the boiler contained 1.5 per cent 2 - dimethylaminoethanol, and 10 per cent non-aromatic hydrocarbon, the remainder being xylenes.

Title: Improvements in or relating to improved selection circuits embodying saturable magnetic cores
IPC: H03K17/81
Filed: 1954-07-22
Abstract: 754,607. Non-contact-making relays. MONROE CALCULATING MACHINE CO. July 22, 1954 [Sept. 24, 1953], No. 21407/54. Class 40(4). [Also in Group XIX] Binary signals represented by positive and negative impulses are selectively recorded on various tracks of a magnetic drum 25, Figs. 1 and 2, under the control of a magnetic switch which comprises saturable cores 35 having commoned input windings 38 and separate output windings 36 connected to recording and reproducing heads 26. Each core is formed of supermalloy or permalloy tape and carries in addition two or more control windings 40 which are selectively energized over triodes 41 in accordance with a binary decimal code so that all the cores except one are saturated, a transformer coupling between input and output windings being then restricted to the unsaturated core. The controlling code is applied from a selection control unit 42 to one or more pairs of leads 431, 431<SP>1> to 434, 434<SP>1> and energizes the triodes in pairs in such a way that when a valve controlled by one lead of a pair is conducting, the other is cut-off. A relay 33 connects the commoned input windings 38 to recording or reproducing circuits 30, 31, the magnetic switch and unit 42 determining the track to be scanned in both cases. To prevent the induction of switching transients during selective recording and reproduction, each saturable core may be duplicated, Fig. 3, with respective control windings 40, 40A arranged to induce opposing transient voltages in the seriesconnected input and output windings 38, 38A and 36, 36A. Alternatively, the effect of transients may be minimized by connecting a series resistor and a shunt condenser between each lead 43 and the associated triode grid. In some cases a pyramid or cascade arrangement of saturable cores may be used, Fig. 4 (not shown).

Title: Improvements in or relating to the production of alcohols by catalytic hydration of olefins
Inventor: RINDTORFF ERMBRECHT
IPC: C07C29/04
Filed: 1962-06-06
Abstract: Alcohols are produced by the catalytic hydration of olefins in the gaseous phase, the gas mixture resulting from the hydration being washed with a solvent which dissolves the by-products and the gas saturated with solvent which is thus obtained being freed from solvent by washing it with water and then recycled to the hydration step.  Preferably the crude alcohol formed in the process is used in the first washing step.  However, other alcohols, ketones and hydrocarbons may be used in this washing step.  An example is given of the conversion of ethylene to ethyl alcohol.  Specifications 900,627 and 950,619 are referred to.

Title: Noise abatement method and apparatus

Filed: 1964-05-27
Abstract: 1,071,095. Propelling ships. UNITED AIRCRAFT CORPORATION. May 27, 1964 [June 4, 1963], No. 21949/64. Heading B7V. [Also in Division F1] The specification describes methods of reducing the operating noise of a multi-stage axial flow compressor having regularly circumferentially spaced rotor and stator blades. Such methods are stated to be applicable to a multistage axial flow ducted marine propeller (11), Fig. 19 (not shown), mounted on the hull of a ship (17). Five basic methods are described, the first being to construct the machine such that each stage of rotor blades is spaced axially downstream from its stator blades by about 5 chord lengths of the aerofoil section of a stator blade, thus diffusing the stator wake before it is cut by the rotor. Secondly, the numbers of rotor and stator blades in a stage are selected in accordance with equations related to operating speed such that the modes associated with one or more harmonics of noise spin at less than a critical Mach No. and thus decay exponentially. Thirdly, the numbers of rotor and stator blades are selected such that two or more sources of noise at the same frequency and having the same number of lobes would be produced. The rotors and stators are then axially and/or circumferentially indexed with respect to each other so that the modes are 180 degrees out of phase and cancel. In the fourth and fifth methods, respectively, the numbers of rotor and stator blades are selected so that the noise pattern will have 8 or more lobes, or the propagating modes have a frequency above the limit of sensitivity of the human ear at 7000 cycles/second.
