Title: Single site ranging system
IPC: G01S3/38
Filed: 1966-02-01
Abstract: 1,139,193. Radio position finding; aerial systems. UNITED STATES OF AMERICA SECRETARY ARMY OF. 1 Feb., 1966 [1 Feb., 1965], No. 4369/66. Headings H4A and H4D. The invention relates to a method of determining the direction and range of a radio source 68, Fig. 4, radiating a field having a spherical wave front 69, by adjusting an aerial array A, B, C such that the received signals produced by each aerial are in phase. This is done by having three co-linear equally spaced aerials, initially placed with their joining line 10, 9, perpendicular to the direction of the source 68, and introducing a delay in the output of the middle aerial, electrically equivalent in wave length terms to the distance L by which the middle aerial is nearer to the source than the two outer aerials. The three aerials array A, B and C, Fig. 1, is thus initially aligned to be at right angles to the direction of the source 68. Signals received by aerials A and C are thus in phase and are equalized in amplitude by attenuators 35 and 36. The initially out of phase signal received by antenna B is passed via phase shifter 41 to a first hybrid junction 30 where it is divided equally into two halves and each half fed to sum and difference signal producing hybrid junctions 24 and 25. The other input arms of junctions 24 and 25 are fed with the signals from aerials A and C respectively. The sum signal from hybrid 24 and the sum signal from hybrid 25 are added in a hybrid junction 45, to produce a final sum signal which is detected at 11 and fed to a meter 64. The initial othoganol alignment of the array is indicated by a maximum reading at 64. The difference signal from hybrid 24 and the difference signal from hybrid 25 are added in hybrid 53, to produce a final difference signal which is detected at 12 and fed to a meter 65. The phase shifter 41 is varied until a null reading is obtained on meter 65, and, by means of a calibration curve 70 such as shown in Fig. 5 (not shown), the wave length delay introduced by the phase shifter 41 can be converted to the range R of the source. The alignment of the array and the adjustment of the phase shifter may be done automatically by a servo-process. As an alternative the array may be continuously rotated at say 10 r.p.m. and the phase shifter may be cyclically altered at say 20 Kc/s. Operation may be from 8,000-12,000 Mc/s and the minimum aerial spacing 34ft.

Title: Improvements in or relating to compositions containing diarylamines
IPC: C09K15/18
Filed: 1955-02-18
Abstract: Solid, frangible, dry compositions comprise essentially a predominant amount of a dialkylated diarylamine of the formula <FORM:0769733/IV(b)/1> where R1, R2, R3 and R4 are halogen, hydrogen or alkyl of 1-4 carbon atoms, and R5 and R6 are alkyl groups of 6-12 carbon atoms and a minor amount of a monoalkylated diarylamine of the formula <FORM:0769733/IV(b)/2> and are made by cooling while agitating a liquid mixture having the same composition until about 55-80 per cent of the latent heat of crystallization has been removed, and then rapidly cooling to remove the remainder of such heat.  The first cooling is continued until the temperature is within the range of the initial crystallization point temperature of said composition to the set point temperature of the dialkylated diarylamine, giving a semisolid composition.  An example describes the reaction of diisobutylene with diphenylamine in presence of aluminium chloride to give a mixture which, after washing with water and caustic soda solution and vacuum distillation to remove some monooctyl diphenylamine, gave a mixture comprising 5 per cent monoctyldiphenylamine and 95 per cent p,p1-dioctyldiphenylamine; this mixture is cooled with water at 65 DEG  C. while agitating and passing during 6 seconds through a tube, from which it is extruded as a semi-solid at 90 DEG  C. on to a conveyer belt at 10 DEG  C.  The use of the product as an antioxidant for rubber is described.  Other diarylamines and alkenes which may be condensed therewith to give the liquid mixtures are listed.ALSO:A solid dry antioxidant for rubber comprises a predominant amount of a dialkylated diarylamine of the formula: <FORM:0769733/V/1> where R1, R2, R3 and R4 are halogen, hydrogen, or alkyl of 1-4 carbon atoms, and R5 and R6 are alkyl groups of 6-12 carbon atoms, and a minor amount of a monoalkylated diarylamine of the formula: <FORM:0769733/V/2> made by agitating and cooling a liquid mixture of the same composition to within the temperature range from the initial crystallization point of the mixture to the set point of the dialkylated diarylamine, giving a semisolid composition, thus removing 55-80 per cent of the latent heat of crystallization, followed by cooling substantially below the initial crystallization point (see Group IV(b)).  The use of such a mixture comprising 5 per cent monooctyldiphenylamine and 95 per cent p p1-dioctyldiphenylamine in a rubber mix having the usual ingredients is described.

Title: Improvements in or relating to pneumatic tube conveyor systems
IPC: F04D29/46
Filed: 1933-02-17
Abstract: 415,102. Pneumatic despatch systems. MIX & GENEST AKT.-GES., 5, Geneststrasse, Sch÷neberg, Berlin. Feb. 17, 1933, No. 4932. Convention date, Feb. 24, 1932. [Class 116.] A pneumatic tube conveyer system has groups of incoming and of outgoing tubes connected by a single tube from which the carriers selectively control their passage to the outgoing tubes together with means for feeding the carriers singly and in sequence from the incoming tubes into the single tube. The carriers from the tubes 1 open flaps 2 and pass to tubes 5 in which they are released in succession to pass through selective switching contacts 8<b>, 9<b>, 10<b> operating corresponding relays 8<a>, 9<a>, 10<a> controlling switch members 8, 9, 10 for directing the carrier into one of the outgoing tubes 11. The sequential release of the carriers in the tubes 5 is effected by angularly displaced cams 22 on a common shaft. With a cam 22 in a non-operative position, Fig. 2, the projecting end of an arm 14 retains the carriers x, y, in the tube whilst a finger 19 holds an arm 16 in an inoperative position with respect to the carrier y. When, as shown in Fig. 3, the raised portion of the cam 22 engages a roller 21 the arm 17 is rocked and the arm 14 is moved so that the carrier x is released. Simultaneously the arm 16 which is no longer retained by the finger 19 moves under the action of a spring 20 to grip frictionally the carrier y. When the cam projection passes the roller 21, the arms 17, 14 are returned by a spring 23 to their positions shown in Fig. 2, whilst the arm 16 is moved away by the finger 19, allowing the carrier y to drop to the position in which it is held by the projecting end of the lever 14. In the tubes 11, the cam 29 operates sets of levers 24, 26, 27, simultaneously so that a definite interval is provided between the release of successive carriers in the tubes. The carriers pass from the tubes 11 to further selecting mechanism similar to that shown in connection with the single tube 6. The carriers in their passage through the tubes 11 open the locking circuits of the relays 8<a>, 9<a>, 10<a>, Fig. 4 (not shown).

Title: Process for stabilizing textile material
IPC: D06M13/123
Filed: 1944-03-21
Abstract: Textile material formed predominantly of regenerated cellulose is stabilized with respect to dimensional shrinkage and is rendered resistant to wrinkling, crushing and creasing without impairing its original softness, by treating it with an aqueous solution containing the equivalent of 15-120 c.c. of 30 per cent by weight glyoxal solution and 0.125 to 4 grams of an acidic catalyst and 12-50 grams in all of one or more amino-aldehyde water-dispersible thermosetting resinous condensation products per litre of treating solution, and baking the treated textile material at 212-350 DEG  F. for 40-2 minutes so as to effect a reaction between the glyoxal and the fibres of the material.  A soft hand or feel may be imparted to the material by including in the treating bath a cation-active softener.  The textile material may be in the form of fibres, yarns, fabrics or garments.  The acidic catalyst may be oxalic acid, ammonium chloride, ammonium sulphate, or ammonium nitrate.  In an example, viscose rayon fabric is impregnated with a solution in water of glyoxal with oxalic acid and urea-formaldehyde condensed to a stage such that it is completely dispersible in water but not sufficiently soluble to produce a clear solution.  The fabric is squeezed, dried on a tenter frame and then cured in a hot oven.  In other examples, fabric of viscose and cellulose acetate, and fabric of viscose and casein fibres, are subjected to the treatment. Urea-formaldehyde, a urea - butyl - urea - formaldehyde p  co-condensation product, or melamine-formaldehyde is used as the thermosetting resinous product. Mixtures of these compounds may be used.  In another example, the impregnating solution contains a quaternary ammonium compound, octadecyl oxymethyl pyridinium chloride.  The cation-active substance may be a quinolinium, or acridinium compound.  It may be the salt of a strong or weak acid, e.g. hydrochloric, acetic or formic acid.  The treatment may be applied to viscose, cuprammonium and completely saponified cellulose acetate materials.  It is also applicable to materials containing regenerated cellulose and other fibres, e.g. viscose and cellulose acetate, casein, soyabean protein, peanut protein, wool or cotton.  Specification 585,679 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the treatment of cotton and other textile materials.  This subject-matter does not appear in the Specification as accepted.
