Patent GB-422360-A (GB)
Title: Manufacture of products from polymeric carboxylic acids
IPC: A61K31/78
Filed: 1933-11-06
Abstract: Compounds of polymeric carboxylic acids with heterocyclic bases are manufactured by causing the acids or their salts to react in a suitable medium, e.g. water, with a heterocyclic base or a salt thereof.  In the case of bases of inferior basicity or of high molecular weight, a portion of the base may be combined with the polymeric carboxylic acids by peptization instead of by salt formation.  The product may be separated from the medium in which reaction has occurred by filtration and washing, if it is insoluble therein, or by addition of a precipitant and purification by extraction if it is soluble in the said medium. The products may be dissolved in water, if required, with the addition of a weak alkali (e.g. dilute caustic potash, alkali carbonate, ammonia or organic bases such as oxyethylamine) or of an organic solvent, or in some cases in an organic solvent alone, and the solutions may be cast on a support, spun or sprayed for the production of films, sheets, plates or layers.  The products may also be moulded by pressing, melting or shaping them by methods used for celluloid, if desired with the addition of softening or filling agents.  They may also be used medicinally for inward or outward application as colloidal solutions or films; for the extermination of plant pests; as anti-parasitic adhesive layers; in the dyeing industry, e.g. by applying the compounds of the polymeric carboxylic acids with heterocyclic basic dyestuffs or intermediates to the dyeing of fibres of all kinds; as lake-formers, e.g. with silver halides, if required in the presence of a binding agent or a diluent; as lacquer layers, light filter layers, protective coatings, or intermediate layers, e.g. for photographic purposes.  In examples: (1) quinine (liberated from its sulphate by means of caustic soda) is suspended in water and methyl alcohol and mixed with an aqueous solution of polyacrylic acid; the product is dissolved in methanol with the addition of aqueous ammonia and glycol monomethyl ether and the solution is cast on a glass plate to produce a film which absorbs ultraviolet light; it may also be used medicinally as a quinine preparation; the polyacrylic acid may be replaced by the product obtained by the action of water on the mixed polymerization product of styrol and maleic anhydride; (2) crude nicotine is dissolved in an aqueous solution of excess of polyacrylic acid, producing a solution suitable for application to plants, if desired, after adding any of the known assistants; (3) methylene blue is reacted with polyacrylic acid in aqueous solution; a solution of the product in a solution containing excess of polyacrylic acid may be used for the preparation of sheets or for directly dyeing cotton.  Specifications 420,533 and 420,589 are referred to.
Patent GB-1287058-A (GB)
Title: Maximum engine speed limiting ignition system
IPC: F02P11/02
Filed: 1970-06-25
Abstract: 1287058 Automatic control of speed FORD MOTOR CO Ltd 25 June 1970 [23 July 1969] 30835/70 Headings G3R [Also in Division F1] In a maximum speed limiting ignition system for an I.C. engine, when the engine is operating below a predetermined maximum speed the ignition coil 20, contact breaker 29, capacitor 38 and distributer 46 function in the conventional manner to energize spark plugs 52. Moreover, the pulses produced by the breaker 29 are applied to an input filter where they are limited in voltage value and shaped into substantially rectangular waveform. Thereafter they are applied to an inverter 79 which applies negative going pulses to an OR gate 84 delivering positive going pulses to a differentiator. The latter applies positive going pulses or spikes to an integrator or sawtooth wave generator 100 to periodically reset the sawtooth waveform to zero in timed relation with engine speed. The output of integrator 100 is applied to comparator 106 which also receives a reference voltage from supply 112. As long as the engine speed is below the predetermined maximum speed, the sawtooth wave voltage is equal to or above the reference voltage so that the comparator 106 supplies rectangular pulses to a capacitor 122 to charge the latter. However, when the engine speed exceeds the predetermined maximum value, the sawtooth wave does not have time between pulses to reach the value of the reference voltage. Consequently the comparator 106 does not produce an output pulse, and the capacitor 122 discharges through an inverter driver and causes a solid state switching device 60, preferably a silicon controlled rectifier, to direct a large portion of the current from the ignition coil to earth. Thus insufficient voltage is supplied to the spark plugs 52 so that the engine speed falls below the predetermined maximum speed, but sufficient current will remain to operate the inverter, OR gate and differentiator. A second comparator 90 receiving the integrator output and a smaller reference voltage than the one supplied to comparator 106, applies a negative going pulse to the OR gate during each period when the sawtooth wave pulses are building up to the value of the said smaller reference voltage, so that the output of the OR gate will always be positive during such periods. The time of the period is selected to be sufficient to ensure spurious signals, e.g. due to bouncing of the breaker points, are damped and therefore do not inadvertently supply extra positive going pulses to the input filter.

Title: Improvements in or relating to a process and means for synchronising transmitting andreceiving apparatus for use in picture and the like telegraph systems
IPC: H04N1/36
Filed: 1927-11-23
Abstract: 281,302. Telefunken Ges. fiir Drahtlose Telegraphie. Nov. 24, 1926, [Convention date]. Synchronous movements.-Transmitting and receiving apparatus in copying telegraph systems are synchronized by modulating a transmitted carrier wave by synchronizing frequencies proportional to the speed of the transmitting apparatus, Fig. 1, in addition to and lying outside the band of frequencies corresponding to the picture or the like, separating the picture and synchronizing frequencies at the receiver, Fig. 2, and employing the latter frequency to control or drive the receiving apparatus so that the latter follows any changes of speed which occur in the transmitter. The picture frequency is obtained from a light-sensitive cell 2 and the synchronizing frequencies, which are lower than the picture frequencies and modulate the carrier wave to a less extent, are generated by an inductor 19 positively coupled to a motor 5 which drives a drum 1 carrying the picture. Instead of impressing the synchronizing frequencies on the grid circuit of an amplifying valve 24 by a transformer 26, as shown, they may be used to heat the filaments of the amplifying or transmitting valves. The picture and synchronizing frequencies are separated at the receiver by filters 32, 33. The synchronizing frequencies may be supplied directly through an amplifier 34 to a synchronizing motor 36, or the motor may be driven from a local synchronous circuit controlled by the synchronizing frequencies.

A helicopter rotor swash plate comprises rings mounted concentrically with the rotor shaft and corresponding ir number with the rotor blades the rings being rotatable rela tive to one another, anc secured against axial move ment between two inclinable but non-rotatable swash plate parts, these two parts being rigidly connected. In the Figure, a boss 3 on the rotor head 2 engages splines 1a on the rotor shaft 1, relative axial movement between the head 2 and shaft 1 being prevented by nut 4. A non rotating sleeve 5 on the drive shaft has spigots 6, on which the non-rotary swash plate parts 14, 15 are tiltably mounted by arms 7. Rotatably mounted between parts 14 and 15, on ball races 16, are five rings 9, 10, 11, 12, and 13, there being five blades on the rotor. The uppermost ring 9 has a flange 9a to prevent ingress of foreign matter. Mounted on the inner surface of the rotor head are five equally spaced two armed levers 17 (one shown). One arm 17b of each lever is connected by a rod 20 to operate pitch change or lag-lead angle controlling mechanism of one blade, and the other arms 17a (one shown) are pivotally connected by stub shafts 18, one to each of the rings 9-13. Each shaft 18, except that on ring 9, passes through a slot 9b in flange 9a. When the swash plate is tilted on spigots 6 by means not shown, cyclic oscillation of the levers 17 is caused. This involves cyclic oscilation in azimuth of each shaft 18 relative to the rotor head, this movement being accommodated by displacements in azimuth of the rings 9-13 relative to one another and to the parts 14, 15.

Title: Method of and installation for the continuous extraction of magnesium with milk of lime from sea waters and the like
IPC: C01F5/22
Filed: 1955-11-08
Abstract: Magnesium oxide is obtained from sea-water or other aqueous liquids containing dissolved magnesium salt by precipitation of magnesium hydroxide with milk of lime, the reaction mixture being subjected to supersonic vibrations.  The suspension of reaction products is passed to an adjacent or surrounding decanting vessel and the precipitated solid is withdrawn from the bottom, washed and calcined to magnesium oxide.  If desired, the precipitation may be effected in the presence of iron or aluminium salts and the precipitated oxides are thereby mixed with the magnesia.  As shown in the <PICT:0821939/III/1> drawings, sea-water is fed to an inner vessel, formed by walls 38, provided with an agitator 3 and a generator 5 for supersonic vibrations.  Milk of lime is pumped from tank 14 through lines 17 and 18 and the resulting slurry of magnesia passes over the top of wall 38 into a surrounding annular chamber 8 where the suspension settles. Supernatant water is restored at 13 and the precipitated magnesium hydroxide is withdrawn through line 25 and passed through a chamber 28 where it is subjected to further supersonic vibrations and then to a washing, centrifuging and filtering device 30.  The resulting magnesium hydroxide passes through a calcining furnace 32 and a cooler 34 and pulverizer 35.
