Patent GB-1463475-A (GB)
Title: Sheet processing machine
IPC: B65H7/12
Filed: 1975-03-19
Abstract: 1463475 Feeding sheets POLYGRAPH LEIPZIG KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSRUSTUNGEN VEB 19 March 1975 [2 April 1974] 11436/75 Heading B8R Control means responsive to the detection of incorrect feed of sheets to a printing machine comprises a means for detecting the presence of two or more superposed sheets being fed to conveying grippers, and first and second sensing means for detecting the relative positions of two superposed sheets. The first sensing means comprises a sensing mechanism 2À1, 2À2 on either side of the feed path, each comprising a longitudinally spaced series of laterally extending slits arranged in light paths to photoelectric receivers, and the second sensing means comprising similar such mechanisms 3À1, 3À2. Signals from the three said means operate, according to the feed condition, means to switch off the printing means while allowing two sheets to be passed through the printing machine, means to stop the sheet separation and feed, and means to divert double sheets to an auxiliary delivery means or to produce an indication that a double sheet is being delivered. In operation, if a single sheet is detected, the first and second sensing means are inoperative and no signal is issued. If more than two sheets are detected, the sheet separation and feed are stopped and the first and second sensing means are inoperative. If two sheets are detected, the printing means is shut off in any case, and the first and second sensing means are operative to determine whether or not the relative position of the two sheets is such as to make it impossible for conveying grippers to feed the sheets through the machine, and if so to stop the sheet separation and feed. If not, the feed continues, but the signal either diverts the double sheet to an auxiliary delivery means or produces an indication that a double sheet is being delivered.

Title: Improvements relating to the preparation of senna products
Inventor: CORRAN ROBERT FREDERICK
IPC: C07H15/244
Filed: 1958-04-11
Abstract: A senna preparation is prepared by adsorbing the glycosides from a liquid extract of senna by forming and precipitating aluminium hydroxide in situ in the extract.  An aqueous solution of a soluble aluminium salt e.g. sulphate, ammonia alum or potash alum is added to the liquid senna extract followed by an aqueous solution of an alkali especially sodium, potassium or ammonium hydroxide to produce a pH of 6,8 to 7,2 and the precipitated aluminium hydroxide with adsorbed glycosides is separated and dried at a temperature below 55 DEG C. The powder so produced may be incorporated in tablets, plain or coated, pills, chocolate, granules and other oral preparations. Alternatively, the glycosides may be eluted from the adsorbate by means of acid or alkali.  The extract may be made from whole pods, ground or unground or from deseeded pods.  Water is the preferred solvent but aqueous methanol, aqueous ethanol or aqueous acetone may also be used.

Title: Improvements relating to substances adapted to decrease blood pressure
IPC: A61K35/22
Filed: 1935-04-15
Abstract: A substance producing a decrease in blood pressure and which is resistant to boiling is obtained from urine by a process involving boiling the urine, or a fraction thereof containing the active substance, before, during or after the employment of the methods normally employed for separating from urine hormones which are insoluble in lipoid solvents.  These methods are precipitation, adsorption, or diffusion and may be used separately or in combination.  Ovarial hormone, if present, may be separated, for instance, by extraction with ether or by precipitation with alcohol. According to examples: (1) urine is boiled, treated successively with barium chloride and sodium sulphate to precipitate impurities and then with a large quantity of methyl alcohol to precipitate the active substance which is then centrifuged, washed with alcohol and ether, and dried; (2) urine is boiled, evaporated to dryness, the dry residue washed with alcohol and ether, taken up in water and treated with methyl alcohol to precipitate the active substance; (3) urine is treated with methyl alcohol and the precipitate washed with alcohol and ether, dissolved in water, and the solution subjected to dialysis or electro-dialysis and finally boiled; (4) urine is treated with charcoal to adsorb impurities, filtered, boiled, and treated with methyl alcohol to give a precipitate containing the active substance which is washed and dried.

Patent GB-648830-A (GB)
Title: Improvements in the manufacture of organic polymeric fibers
IPC: D01F2/06
Filed: 1947-05-01
Abstract: <PICT:0648830/IV (a)/1> <PICT:0648830/IV (a)/2> <PICT:0648830/IV (a)/3> Fibres obtained by extrusion of organic fibre-forming solutions are subjected, before they are finally set, to high-frequency sound wave radiations, of frequency in the range of about 1000 to several times 107 cycles per second.  The process is particularly applicable to fibres of regenerated cellulose from viscose, being applied either to the spinning bath or soon after withdrawal while still moist with acid from the bath.  The rate of diffusion of residual acid may be controlled by the sound waves. Preferably, in addition to the stretch imparted on leaving the jet, the fibres are given a predetermined stretch between rollers, the removal of xanthate being completed soon after the fibres leave the stretching zone.  The sound waves may be applied either directly or indirectly to the fibres, threads or yarns at all stages in their manufacture, while they are in the highly plastic state, from the time of formation in the bath to the usual after-treating processes. If desired, they may be applied before, during or after stretching, after collection in the form of a yarn package, or during storage, to permit complete regeneration, and they may be applied in any direction, parallel or transverse to the thread.  The waves may be generated by piezo-electric, magneto-strictive or electromagnetic generators or the like.  As shown in Fig. 1, the sound generator 7 is provided with a tube 9 up which the fibres travel from the spinning bath, emerging through a slot 10 before passing round rollers 5, 6 which apply a stretch.  Fig. 2 shows an arrangement in which the threads are treated after stretching, and in Fig. 4 the sound waves are applied directly to the coagulating bath and indirectly to the fibres as they are formed.  The process is applicable also to regenerated protein fibres in the initial plastic condition and to fibres of cellulose esters obtained by wet or dry spinning.
Patent GB-775362-A (GB)
Title: Method of and apparatus for roasting fine grained sulphidic ores
IPC: C22B1/10
Filed: 1954-04-22
Abstract: Fine grained sulphidic ores such as glances, blendes (e.g. zinc blende) and pyrites are roasted to form sulphur dioxide by being set in spiral upward motion in a grateless reaction furnace by an injected current of air, withdrawing a portion of the entrained particles and returning them to a lower part of the <PICT:0775362/III/1> furnace.  By this means a suspension of coarser particles is maintained in the furnace.  In a described embodiment (see Fig. 1) ore particles and if desired roasted fines from a later stage are charged into a furnace 1, divided into upper and lower sections 7 and 4 by constricted portion 6, through inlets 11 and 12 by means of air jets, or through a conduit or conduits 8 through which the air for roasting also enters.  It is stated that the upward spiral air current may be provided either by a plurality of conduits 8, tangentially disposed and upwardly inclined or by a single conduit 8 in which is inserted a fixed or rotating nozzle, details of which are given, which imparts a swirling helical motion to the injected current of air.  It is further stated that particles falling into the lower part of the furnace should be able to pass through said nozzle, although larger ones may be collected in trap 9.  Recirculation is provided for by a pipe or pipes 16 into which air may be injected at 18.  After roasting in chamber 1 the particles pass into sintering or after-roasting chamber 2, which is similarly constructed at the bottom, and from which the product is discharged through trap 10 and a cyclone (not shown) in pipe 14.  Fine ducts may alternatively be returned to chamber 2 where sintering together to form coarser particles takes place. When after-roasting in chamber 2, air or recycled gas is used. The invention may also be modified or improved by (a) incorporating into the upper part of furnace 1 a cyclone which returns material to the lower part of said furace in place of pipe 16; (b) the furnace comprising only one chamber, in which case it may be surmounted by a sintering chamber corresponding to chamber 2; (c) superimposing upon the helical air current intermittent vibrations by introduction of blasts of compressed air or by the presence of a vibrating valve before the nozzle in pipe 8 or (in the case of a stationary nozzle) by disconnecting one or more of the passages therein in sequence; (d) cooling the furnace by means of a water jacket or cooling tubes placed upon it, or by the introduction of cold air or air at 150 DEG C. through nozzles 15; (e) injecting additional ore through pipe 13 to produce the desired sintering temperature.

Patent GB-572915-A (GB)
Title: Improvements in production of glycols
IPC: C07C29/10
Filed: 1944-06-22
Abstract: <PICT:0572915/IV/1> Glycols may be prepared by the hydration of an olefine oxide dissolved in water containing an acid hydration catalyst, preferably sulphuric acid, and the resulting glycol solution separated from the free acid and that portion of the acid which is in combination with the glycol and is not precipitated by addition of barium chloride, by passing the glycol solution through an anion absorbing resin.  Any resin of the anion-absorbtion type may be used; they are, in general, the product of condensation of organic amines or similar basic materials with formaldehyde.  As examples of commercially available resins, there may be mentioned one known as "Anex" which is believed to be a melamine resin and another known as "Amberlite IR-4" which is the condensation product of aromatic amines such as aniline with formaldehyde.  The process may be carried out in the apparatus illustrated wherein a deep bed of the resin 6, which may be in the form of particles ranging in size from 16 to 50 mesh, is supported in a column 5.  The glycol solution is introduced through a pipe 7 at a relatively low rate so that when the solution leaves the apparatus, via pipe 9, it will contain no free or combined acid.  The operation is preferably carried out at room temperature. The spent resin may be regenerated by first flushing the bed with water to remove the glycol solution and then introducing an aqueous solution of sodium carbonate and finally rinsing the bed with water; suitable connections 10 and 11 are provided for this purpose.  The acid-free glycol solution may be passed to a multiple effect evaporator and after concentration, distilled to recover the glycol. A reference is made to the preparation of ethylene glycol by the catalytic hydration of ethylene oxide as set forth in Specification 498,119.
