Title: Improvements relating to ranging and direction finding equipment
IPC: G01S1/02
Filed: 1947-05-23
Abstract: 642,665. Ranging and direction-finding equipment. SCOLES, G. J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 23, 1947, No. 13931. Drawings to Specification. [Class 40 (iii)] [Also in Group XL (c)] An echo-ranging and direction-finding system using continuous-wave radiant energy comprises a sharply directive-transmitting system which is continuously rotated at a high speed and a sharply directive-receiving system which is adapted to be also rotated continuously but at a relatively low speed, together with indicating equipment comprising means for measuring the time intervals between the instants when the directivities of the transmitter and receiver coincide and the instant of reception of echo signals. The system may employ radio, light, infra-red or sonic wave-transmission. In one arrangement a narrow beam of radiation is directed along the vertical axis of rotation on to a 45 degrees rotating mirror, whereby a rotating beam is radiated. The receiving system, employing a concave mirror, is rotated at a comparatively slow rate, and means, employing, for example, a set of contacts or a photo-electric cell, is arranged to trigger a time-base at the instant when the two directive patterns coincide. The time-base is made to rotate with the receiving system to provide a P.P.I. display. The receiver is not necessarily continuously rotated; it may be manually controlled to investigate a particular direction. Moreover, the waves may be radiated in a direction which is not perpendicular to the axis of rotation, so that a conical scan is performed. Also the axis may be other than vertical and may, in some cases, itself vary in direction.

Title: Separation of materials
IPC: B01D59/34
Filed: 1975-04-04
Abstract: 1501238 Separation by diffusion under the influence of electric and/or magnetic fields KRAFTWERK UNION AG 4 April 1975 14005/75 Heading B1L [Also in Division G6] In a method of separating components from a gaseous mixture of substances or isotopes, a beam of plane polarized electromagnetic radiation 6 is passed through the mixture and has its frequency selected so that the dipole behaviour of the individual components of the mixture is selectively and/or differentially influenced so that the components become spatially separated by the electric and/or magnetic field of the beam. As particularly described, an alternating electric field, produced by a laser or a maser, acts upon molecules (which may have a permanent dipole moment, or merely an induced dipole moment) to cause oscillation. By providing an electric field strength which, in relation to the beam cross-section, does not have the same value everywhere but has a gradient in, or opposite to, the direction of the field, an electric force acts on the molecular dipole. Thus, if two species, for example, isotopes, having different resonant frequencies, are in the exciting field then, by suitable choice of the exciting frequency, the two species can be separated by deflection in opposite directions. Two apparatuses for applying the method are described. In one form of apparatus (Figure 8) a container 1 is divided by a heat-insulating wall 3 into a storage chamber 2 for a mixture to be separated and an evacuated chamber 5. The two chambers 2, 5 are interconnected by an elongate Laval nozzle 4; additionally the evacuated chamber 5 is divided into two parts 51, 53 by an orificed plate 52. This acts as a collimator for the gas beam emerging through the Laval nozzle into the evacuated chamber 5. A bundle of laser beams 6 traverses the chamber 5 immediately downstream of the orifice plate 52. The vector of the electric field of the plane-polarized laser beams 6 is vertically oriented. Mirror systems 61, 62 reflect the beam back and forth several times. A rear wall of the container I is formed into collecting regions 54, 55 for receiving different portions of the mixture which are separated as described above. Preferably, the laser source 63 has an adjustable frequency. Reference is made to the separation of isotopes of the following elements: uranium, chlorine, boron, tungsten, neptunium, and plutonium. In a second form of apparatus (Figure 9) a tube is divided into a series of end-to-end chambers 101, 102, 103 separated by walls 116 permeable to radiation. Each chamber has a central inlet 110A-110C and end outlets for the different, separated components. A laser beam 115 enters the tube at one end and is caused to traverse the tube, parallel to its length, several times by mirror systems 117, 118. The individual chambers 101-103 may be operated in parallel or in cascade so as to increase the separative effect. Deflection is conducted, in this case, using the magnetic component of the laser beam.

Title: Improvements in or relating to coating compositions
IPC: C09D101/18
Filed: 1940-09-13
Abstract: 543,913. Cellulose derivative compositions ; resinous condensation products. DU PONT DE NEMOURS & CO., E. 1. Sept. 13, 1940, No. 14163. Convention date, Sept. 27, 1939. [Classes 2 (ii) and 2 (iii)] A coating composition comprises a polyvinyl butyraldehyde resin and a cellulose derivative compatible therewith, the proportions falling between 75 parts of resin to 25 parts of cellulose derivative and 25 parts of resin to 75 parts of cellulose derivative. Preferably, it comprises also a synthetic or natural resin which is compatible with the other two ingredients. The composition is particularly suitable for priming purposes. It may be applied by spraying, brushing, dipping, or other methods to wood or other surfaces. It gives .coatings which are themselves resistant to scratching and which impart a high degree of scratch-resistance to superposed top coatings. The polyvinyl resin may be obtained by treating a polyvinyl acetate with a hydrolysing agent (e.g. sulphuric acid) and condensing the product with butyraldehyde to give a solid but soluble resinous body. It may be condensed to the extent of 80 per cent. of butyral groups with not more than 2 per cent. of residual acetate groups and 18 per cent. of residual hydroxyl groups. The cellulose derivative may be cellulose nitrate or ethyl cellulose. The additional resin may be shellac, or a sulphonamide resin such as formaldehyde-p-toluene sulphonamide resin. In an example, polyvinyl butyral resin is mixed with cellulose nitrate of low viscosity type, shellac, ethyl alcohol, n-butyl alcohol, toluol, n-butyl acetate, amyl acetate, and ethyl acetate. The polyvinyl resin used gives a viscosity of 3,000 centipoises when in the form of a 20 per cent solution in a mixture of denatured ethyl alcohol 52 per cent., and toluol 28 per cent. When the primer coating is dry, it is roughened by sanding and then a top coat of cellulose lacquer is applied. This may consist of low viscosity cellulose nitrate, blown castor oil,. damar resin, ethyl alcohol, n-butyl alcohol, ethyl acetate, n-butyl acetate, toluol, and petroleum naphtha. The polyvinyl butyraldehyde composition may be used for coating steel surfaces. It may be used for enamelling finger nails, a top coat of a cellulose nitrate composition being subsequently applied. The primer coating may be provided with a top coat of varnish, paint, or other finish having a basis of cellulose derivative, oleo-resin, alkyd-resin, urea-formaldehyde, phenol-formaldehyde, polyvinyl resin such as a polyvinyl chloracetate, or a vinyl acetate.
