Title: Noise suppressor and thrust reverser for jet propulsion engines
IPC: F02K1/56
Filed: 1958-05-29
Abstract: 861,819. Jet deflection on aircraft. BOEING AIRPLANE CO. May 29, 1958 [July 29, 1957], No. 17196/58. Class 4. [Also in Group XXVI] An aircraft jet propulsion engine comprises an elongated housing having an interior duct wall terminating in a rearwardly directed jet nozzle, a bulbous plug radially divided into axially extending segments and means for radially shifting certain of the segments which are circumferentially spaced between an inner position in which they form with the remaining segments a stream lined plug spaced from the duct wall by an annular duct and an outer position in which gas discharge passages are opened along the spaces previously occupied by the shiftable segments in addition to passages formed outside the non-shiftable elements. The housing also has a terminal portion which can be shifted rearwardly to close the annular duct between the plug and the duct wall and open up a gap in the side wall of the housing for thrust reversal purposes. In Fig. 1, a central island body 90 supports a segmented bulbous plug 1. Surrounding the body is a housing 9 having an axially movable terminal portion 8, the inner wall 80 of which forms with the plug an annular duct 91a terminating in a nozzle 92. To effect noise suppression alternate segments 1a, Fig. 6 of the plug are projected radially outwards into the jet stream by means of a jack 12 and linkage 11, until they contact the duct wall 80. The jet stream is then divided into numerous smaller jets 91b, 91c, Fig. 6 allowing the ambient air to mix more freely with the jet stream, thus lowering the noise level. For thrust reversal the plug 1 has its movable segments retracted and the terminal portion 8 is moved axially downstream by telescoping actuators 82, 83, until it contacts the periphery of the bulbous plug. As shown in Fig. 4 rearward movement of the terminal portion closes the duct 91a and at the same time opens a gap 98 allowing the blocked exhaust gases to exit in a forward direction. If larger surfaces for impingement and reversal of the direction of thrust are desired louvres 85, may be employed.

Title: Method of determining depth in underwater location
IPC: G01S7/52
Filed: 1959-05-20
Abstract: 1318181 Sonar systems GERMANY DEFENCE MINISTER OF 20 May 1959 [20 May 1958] 17229/59 Heading H4D Corrections needed in finding the depth of an object by echo-sounding are found by sinking, at a known distance from the sounder, a body which sinks at a constant rate, and tracking its descent. The depth measured by tracking will generally differ from the depth calculated from the known rate of descent because of refraction of the sound waves used in tracking, and this enables the refraction to be measured. The object may be a rocket, carrying a panoramic ultransonic transmitter of the same frequency as the echo sounder or a retractable reflector, fired from the ship carrying the sounder.

Title: Method for working up auriferous and cupriferous arsenical pyrites
IPC: C22B15/06
Filed: 1934-06-13
Abstract: In working up auriferous and cupriferous arsenical pyrites or such pyrites in admixture with sulphur pyrites, a part of the ore is roasted and smelted to matte which is blasted in a converter, whilst the remainder of the ore, after roasting, is charged direct into the converter to be blasted together with the matte.  By this procedure, loss of gold in the converter slag is minimized. Roasting of the ore to be passed direct to the converter is so controlled that all arsenic is roasted out whilst leaving the bulk of the sulphur, and so that any iron present remains in the divalent state; such ore should, when possible, have a higher gold and a lower copper content than that part of the ore which is smelted to matte.ALSO:In working up auriferous and cupriferous arsenical pyrites or such pyrites in admixture with sulphur pyrites, a part of the ore is roasted and smelted to matte which is blasted in a converter, whilst the remainder of the ore, after roasting, is charged direct into the converter to be blasted together with the matte.

Title: Improvements relating to amino-type resins as employed for acid adsorption
IPC: B01J41/09
Filed: 1945-07-13
Abstract: An anion exchange synthetic resin is produced by heating dicyandiamide with an aldehyde and an acid or alkaline catalyst until a gel is formed, which is dried, the gel while still wet and/or during and/or after drying being heated to a temperature between 105 DEG  and 125 DEG  C. to convert it to the infusible form without destroying its porous gel structure and to bring its solubility between 1.0 and 2.0.  Solubility is measured by shaking the resin with sulphuric acid, filtering, oxidizing the filtrate with standard potassium permanganate solution and titrating the unused potassium permanganate with sodium thiosulphate.  It is expressed in arbitrary units defined in the Specification.  In an example, 1 mol. of dicyandiamide was heated for 2 1/2 hours on a water bath with 2 1/2 mols. of formaldehyde as 40 per cent formalin in presence of .1 mol. of hydrochloric acid.  The gel dried at 100 DEG  C. for 6 hours yielded a hard glass-like resin which was heated to 110 DEG  C. for 8 hours and ground to pass a 40-mesh sieve.  After activation with sodium carbonate solution and washing, it had an exchange capacity expressed as 6.1 kilograms of CaCO3 per cubic foot of resin.  A similar example is described in which an alkaline catalyst (sodium carbonate) is employed as condensation catalyst.
