Title: Method and arrangement for directional transmission and reception by means of electric waves
IPC: H01Q19/10
Filed: 1925-08-19
Abstract: 242,236. Hahnemann, W. Oct. 29, 1924, [Convention date]. Addition to 237,906. Directive signalling.-To the directional aerial arrangement described in the parent Specification is added a reflecting system comprising a series of individual conductors arranged in rows parallel to the primary aerials, and in layers extending to a depth of not less than half a wavelength. As shown in plan in Fig. 4 the primary aerials 1 - - 5 are backed by five rows of reflecting units 6 - - 10, in staggered relation, the whole being carried by four masts 11 - - 14. Each reflecting unit is spaced apart 'from its neighbours, and is separately earthed. As shown in Fig. 5 the units are separately tuned by means of coils 15. The system may act partly as a reflector to re-inforce the desired directional beam, and partly as an absorber to prevent the backward spread of energy in an undesired direction. Fig. 6 shows two rows of primary antennae A, B separated by a common reflecting system C. Or a single row of antennae may be screened by two reflecting systems arranged back and front, one or other of the reflectors being tuned or detuned, i.e. made transparent or opaque at will. For short-wave working the system may be mounted so as to be capable of bodily rotation.

Title: Control circuit for controlling a pulse width reducing circuit
IPC: G11B20/10
Filed: 1964-05-21
Abstract: 1,005,702. Electric analogue calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 21, 1964, No. 20946/64. Heading G4G. [Also in Division H3] In a pulse shaping circuit (see Division H3) a voltage is obtained which represents the quotient (peak amplitude)/ (area) of an input pulse. The peak amplitude signal 222 (Fig. 3) is obtained by differentiating the pulse and passing it to a zero crossing detector comprising in succession an overdriven amplifier, differentiator, bistable flip - flop, differentiator and single-shot multivibrator. A negative-going pulse thus occurs at the instant of the peak amplitude of the input pulse, and this negative pulse controls a " sample and hold " circuit fed with the input pulse to give a D.C. voltage representing the peak amplitude. The latter is divided by the integrated input pulse at 228, the output being applied to a further gated " sample and hold " circuit and squarer to give an output voltage of the required form at 238.

Title: Process for working up sylvinitic crude salts to a mixture of potassium nitrate and sodium nitrate or this mixture and soda
IPC: C01D9/04
Filed: 1930-07-11
Abstract: A cyclic process for the production of a mixture of potassium and sodium nitrates from sylvinite, in which ammonium chloride or ammonium chloride and soda are obtained as bye-products comprises the following steps: (1) The potassium content of sylvinite is adjusted by addition of potassium chloride so that its potassium-sodium ratio is the same as that in glaserite (3K2SO4.Na2SO4) and the mixture is reacted with ammonia and an ammonium chloride solution containing ammonium sulphate obtained in step (2) to form a precipitate of glaserite, which, after separation from the mother liquor, is treated with calcium carbonate and nitric acid, whereby a precipitate of gypsum containing double sulphates of potassium and calcium such as syngenite or potassium calcium pentosulphate is formed, together with a solution of potassium and sodium nitrates, which is evaporated to dryness; (2) The glaserite mother liquor is cooled to separate out part of its ammonium chloride and then treated with carbonic acid to form ammonium carbonate or bicarbonate which is reacted with the gypsum obtained in step (1) to produce a mixture of ammonium sulphate, ammonium chloride, and calcium carbonate which is used preferably without separation of the calcium carbonate to treat further quantities of sylvinite. Alternatively, sylvinite may be used in step (1) without addition of potassium chloride, in which case the glaserite mother liquor contains sodium chloride in addition to ammonium chloride and ammonia.  Step (2) is modified by subjecting the liquor, after separation of part of its ammonium chloride by cooling, to the Solway process to form soda and the mother liquor therefrom, containing ammonium chloride and carbonate, is then treated with gypsum as before.  Specification 347,935 is referred to.

Patent GB-695567-A (GB)
Title: Super-stretching polyester filaments, yarns, films, and similar structures
IPC: D01F6/62
Filed: 1950-09-01
Abstract: Filaments, yarns, films or like articles are formed of a substantially amorphous synthetic linear polyester and stretched in at least one dimension 10-75 times the original dimension at a temperature which is 20-60 DEG  C. above the apparent minimum crystallization temperature of the amorphous polyester.  Such a treatment results in stretched products which are free from molecular orientation.  If desired, these products may be submitted to a subsequent drawing operation to produce molecular orientation.  This subsequent drawing may be effected at a temperature which is lower than that of the previous stretching operation and which is between the second order transition temperature (Tg) for the polyester and a temperature 30 DEG  C. above the apparent minimum crystallization temperature (T1).  The temperature T1 is the lowest temperature at which a marked density change, known to occur simultaneously with crystallization, takes place within six hours.  The temperature Tg is the temperature at which a discontinuity occurs in the curve of a first derivative thermodynamic quantity with temperature, i.e. in the first portion of the curve showing the relation to temperature of a physical property which is a linear function of the temperature.  It can be observed by plotting density, specific volume, specific heat, sonic modulus, or index of refraction against temperature.  The subsequent drawing operation may be carried out in two stages if desired.  The drawing operation is accompanied by molecular crystallization.  If desired, crystallization may be effected by a heat treatment without the subsequent drawing operation, and the yarn or film may be allowed to shrink.  The initial stretching should be carried out under dry heating conditions, e.g. the yarn or film may be heated in air, glycol, silicone oils or mineral oils.  The polymer is preferably a polymethylene terephthalate, e.g. it may be a polymerized ester of ethylene glycol and terephthalic acid with, if desired, other copolymerizable substances such as diethylene glycol, tetra- or hexa-methylene glycol, hydroterephthalic acid, adipic acid, a naphthalic acid or bis-p-carboxyphenoxyethane.  A polyester having an intrinsic viscosity of at least 0.3 is preferred.  The amorphous state of the polymer is obtained by melt spinning and rapidly chilling the yarn or film as soon as it is formed.  In an example, an amorphous polyethylene terephthalate yarn (Tg=67 DEG C., T1= 99 DEG C.) is run through oil at 127 DEG  C. and on emerging is passed round a roll which stretches it 13 times.  From this roll the yarn is passed round a pin which is heated to 94 DEG  C., and then to another roll which draws the initially stretched yarn to 4 times its length, giving a total length of 52 times the original.  In another example, monofils are stretched and drawn while in the form of a warp sheet, and in another example yarn is heated and stretched while passing through a tube through which hot air travels in counter-current. Specification 578,079 is referred to.
