Title: Improvements in and relating to echo-sounding apparatus for use on noisy aircraft
IPC: G01S7/58
Filed: 1932-03-02
Abstract: 389,646. Echo-sounding apparatus. FLORISSON, C. L., 11, Rue de Cronstadt, Courbevoie, Seine, and SOC. DE CONDENSATION ET D'APPLICATIONS MECANIQUES, 42, Rue de Clichy, Paris. March 2, 1932, No. 6362. Convention date, March 2, 1931. [Class 118 (ii).] In echo-sounding apparatus for use on aircraft, the transmitter and the receiver are each located within a recess in the outer surface of the craft, the mouth of each recess being closed by a sound-permeable partition lying in the surface of the craft so that it neither protrudes therefrom nor produces a depression therein. The transmitter 2 and the receiver 4 are located in paraboloidal reflectors fitted on a smooth surface 1 of the aircraft. The reflectors are provided with acoustic insulating material 6 and are closed by panels 3, 5, preferably of fabric, through which sound can pass. The sound is emitted by a whistle 17 controlled by a valve 20a actuated by an electromagnet 19 energized when contacts 14 are closed by a constantly-rotating cam 13. The echo is conveyed to the ears of the observer by an acoustic channel 7 which is blocked by a device 25 during the emission period. The channel 7 contains an acoustic filter 9. A " false echo is produced by a device 11 and supplied to the channel 7 through an intensity-regulating device 27. The device 11 is actuated by the closing of contacts 21 by the cam 13. These contacts are adjusted angularly round the camshaft until the " false echo " coincides with the actual echo. The extent of this angular adjustment, indicated on a scale 24, is thus a measure of the height of the aircraft. The " false echo " may be different in pitch from the true echo and the formation of beats in the ears of the observer may be utilized as an indication that the two sounds are in coincidence. The acoustic channel 7 may be replaced by an electrical one having a microphone at one end and telephones at the other, the acoustic filter 9 being replaced by a corresponding electrical device.

Title: Methods and equipment for preparing mortar or concrete
IPC: B28C5/46
Filed: 1966-02-14
Abstract: Concrete masses having increased flow properties are prepared by incorporation of numerous gas bubbles which are small relatively to the aggregate, the gas pressure being increased during or after mixing, the concrete masses being made turbulent in the mixing container subjected to an increased pressure. The masses are thus pumpable through pipes more easily and the water content can be kept low.  Optionals are sulphonated fatty alcohols to reduce surface tension; higher fatty alcohols, casein in oil and certain petroleum grades to increase surface tension.  The gas can be air, or an air/Cl2 mixture.

Title: Improvements in the production of polyamides
Inventor: WHEATLEY EDWARD WILLIAM
IPC: C08G69/36
Filed: 1951-03-16
Abstract: Fibre-forming interpolyamides melting at about 250 DEG C. are made by condensing together a polymethylene diamine, a polymethylene dicarboxylic acid and 5-25 molar per cent. based on the total mols. of the reagents of an aromatic amino-carboxylic acid of formula <FORM:0709924/IV (a)/1> where R is a direct bond or is <FORM:0709924/IV (a)/2> , the remaining positions in the benzene nucleus or nuclei being unsubstituted or substituted by methyl groups.  Specified amines are tetra-, penta-, hexa-, and deca-methylene diamine.  Specified acids are glutaric, adipic, pimelic, suberic and sebacic acids. Amide forming derivatives of the reagents may be used, e.g. formyl amino compounds, methyl or phenyl esters, carboxylic amides, or mixed anhydrides of the acids with volatile monocarboxylic acids. Isocyano compounds may be used instead of the amino compounds. All of the reagents may be heated together or the diamine and dicarboxylic acid first condensed, the aromatic amino-acid added and condensation continued.  Condensation may be performed in the melt or in presence of cresols, xylenols or hydroxy diphenyls.  In an example hexamethylene diammonium adipate and paraamino-benzoic acid are heated at 220 DEG C.-280 DEG C. for three hours, the final heating being performed at 2 mm. of mercury pressure to yield a polymer of intrinsic viscosity 0.54.

Abstract: 1415053 Steering vehicles and vessels SVENSKA KULLAGERFABRIKEN AB 9 Feb 1973 [10 Feb 1972 20 March 1972] 6561/73 Headings B7H and B7V In a steering assembly for a vehicle or a vessel of the type in which the rotary motion of the steering wheel 1 is transmitted to the steering gear by a flexible shaft 3, the steering wheel 1 is connected to the flexible shaft 3 via step-up gearing 2 and the shaft 3 is connected to the steering gear via step-down gearing 4. Thus the shaft 3 will have a higher rotational speed than the steering wheel 1 which reduces the torsion spring effect of shaft 3 so that there is no feeling of play when turning the steering wheel. In a first embodiment (Fig. 3) a vehicle is provided with a steering wheel 1 which is connected to the flexible shaft 3 via stepup planetary gearing 2 and a bevel gear (not shown). The shaft 3 is connected to the steering gear 12 via step-down gearing 4. The steering gear 12 includes a nut and screw transmission 8 which converts the rotary motion of the step-down gearing 4 into translatory motion of a rod 9. The rod 9 is pivoted to a steering arm 14 which steers wheels 19 via tie rods 15 and arms 16. In a second embodiment of vehicle steering (Fig. 5) the steering wheel 1 is connected to shaft 3 via step-up planetary gearing 2 and is adjustably mounted on bracket 23 by lever 24. The shaft 3 is connected to the input shaft 10 of step-down gearing 25, 26 and gear 26 is mounted on the nut 27 of a nut and screw steering gear 12. The ends of screw 28 are connected by ball joints 31 to tie rods 15 which steer the wheels as shown in Fig. 3. A servo-mechanism may also be connected to input shaft 10. In a modification two flexible shafts 3, 3<SP>1</SP> are provided and are connected to step-up gearing 2 so that they rotate in opposite directions and the shafts are given oppositely directed torsional prestresses. In a third embodiment (Fig. 6) a steering assembly for a vessel includes a steering wheel 1 which is connected to a pair of oppositely torsionally prestressed flexible shafts 3, 3<SP>1</SP> by means of step-up gearing 2 and the shafts 3, 3<SP>1</SP> are connected to step-down gearing 4. Rotary motion of output shaft 11 of the gearing 4 is converted to translatory motion of rod 9 by means of nut 27 and screw 28 transmission 8. The free end of rod 9 is pivoted to a tiller 35 fitted to the rudder head of the rudder 33. A servo mechanism may be incorporated in steering assembly at a location between stepdown gearing 4 and the screw and nut transmission 8. The vessel may be steered automatically by a control unit 36 having an electric motor (not shown) which drives the steering wheel 1 by chain or belt drive 1. The control unit 36 is powered by a battery 37 and may steer the vessels in response to signals from a compass 38 or from a wind vane 39. In a modification (not shown) the steering gear 8 may be connected to an outboard motor pivotally mounted at the stern of the vessel.

Abstract: 437,885. Reducing surface friction. TENNANT, W. J., 111, Hatton Garden, London.-(Tatra Works Ltd. Motor Car & Railway Carriage & Wagon Builders ; 200, Kartouzska, Smichov, Czecho Slovakia) March 1, 1934, No. 6605. [Class 4] For the purpose of reducing the air resistance of a motor-car, aircraft or other vehicle which, owing to necessity of providing features such as protuberances for mudguards, headlights or curtailed rear parts, cannot be given a true streamline form, the formation of eddy currents at the points where the smooth contour is interrupted is prevented by discharging into the zones of partial vacuum formed at such points air introduced at a zone of pressure, e.g. the front end, and conducted through passages in the body, the flow being assisted, if desired, by fans or engine exhaust. In the arrangements shown diagrammatically air is admitted at the forward end or zone of pressure F of a motor vehicle, e.g. through the radiator passages, and conducted by passages H to zones of partial vacuum formed either at the rear G, Fig. 1, of the mudguards or at the rear part J, Fig. 2, of the body, which is shortened as compared with the true streamline form K.

Title: Improvements in or relating to plugs for pipes and locking means therefor
Inventor: GARDINER TERENCE EDWARD GOUVEN
IPC: G21C13/067
Filed: 1959-02-25
Abstract: 921,770. Reactors. BRISTOL AEROJET Ltd. May 12, 1960 [Feb. 25, 1959], No. 6627/59. Class 39 (4). [Also in Group XXVIII] A plug, for sealing an open end of a pipe which contains gas under pressure and has an internal annular seat facing the open end, has two coaxial parts, of which one is further from the open end of the pipe than the other and has an annular external sealing surface to bear on the seat, and of which the other can be locked to the pipe, the two parts being sealed together but free for axial relative movement and having between them a chamber fed with gas from the pipe so that when the outer part is locked to the pipe the load on the inner part due to gas pressure in the chamber is greater than that due to gas pressure in the pipe. Fig. 1 shows such a plug in a standpipe of a nuclear reactor. The pipe has a conical seat 15 on which bears a spherical surface 26 of the lower part of the plug. The upper and lower parts of the plug are connected by annular bellows 44 and enclose a chamber 13 which communicates with the interior of the standpipe; excessive relative movement of the parts is prevented by shoulders 30, 31, 47 which engage like a bayonet lock, and loss of gas if a bellows breaks is prevented by a flanged sleeve 49. The upper part of the plug is locked by balls 20 which are held in a groove in the pipe by a sleeve 40 which is itself locked by balls 38 held in a groove in the sleeve by the body of the upper part. The ring 39 containing the balls 38 can be rotated to let the balls enter pockets 37 (Fig. 2) and thus release the sleeve; a lifting force applied at 61 will then release the balls 20 and lift the plug. The ring is rotated by pistons 67 which are normally loaded by the pressure in the chamber 13 against springs to hold the ring in the locking position. The lower part of the plug carries a shield plug. An arrangement is described in which a plug according to the invention is used to seal a charging shoot into a standpipe, the shoot being sealed by a second plug.
