Abstract: 920,984. Deflecting propulsive jets. ROLLSROYCE Ltd. Sept. 14, 1961, No. 33080/61. Class 4. A nozzle comprises a hollow casing member through which a fluid is discharged, a hollow support member connected by a first mounting to said casing member, and a hollow outlet member connected by a second mounting to said support member, fluid which is discharged from said casing member passing successively through said support member and said outlet member and being deflected depending on the positions of the support member and the outlet member relative to the casing member, one of said mountings permitting relative rotation between the parts interconnected thereby, and the other of said mountings permitting only relative pivoting movement between the parts interconnected thereby, whereby said outlet member is both rotatable and pivotable relative to said casing member, said nozzle having a drive device for effecting both rotating and pivoting movement of said outlet member relative to said easing member. The invention is particularly applicable to a direct lift engine mounted substantially vertically in an aircraft wherein the lower end of the engine casing 6 carries a bearing 10 to support a curved support member or duct 8, the axis of the lower portion of which is substantially parallel to but laterally displaced from the axis 12 of casing 6. An outlet or nozzle member 14 is pivotally mounted at 15 on member 8 for movement between an overlapping position indicated by lines 20, 21 and the lower position shown in chain dotted lines. An electric motor 27, mounted on easing 6, drives a worm wheel 26 which meshes with a gear ring 29 carried by member 8. A bracket 45 also carried by member 8 forms a trunnion support for a pinion 49 meshing with gear ring 29 and fast with a screw threaded shaft 48 upon which is mounted a nut 52 attached by bracket 54 to member 14. An annular ratchet-device, Fig. 3 (not shown), connects ring 29 to member 8 and stop members 42 on member 8 are arranged to abut a stop bracket 41 at selected positions. Operation of motor 27 initially causes free simultaneous rotation of members 8 and 14 about axis 12 without relative movement between gears 29 and 49 until one or another of stops 42 engages member 41 to arrest member 8. Because of the ratchet device the ring 29 now drives gear 49 to operate the screw jack mechanism 48, 52 to cause member 14 to rock about pivot 15 to a selected inclination.

Title: Improvements in the manufacture and production of halogenanthraquinone-ª‰íúª‡(n)-benzacridones
IPC: C09B5/34
Filed: 1929-10-31
Abstract: Halogenated anthraquinone-b .a  (N)-benzacridones are prepared by treating anthraquinone-b .a  (N)-benzacridone or derivatives thereof other than iodo derivatives, with chlorine or bromine or agents supplying chlorine or bromine in inorganic acid media and preferably in the presence of halogen transferrers.  Inorganic acid media comprise sulphuric acid, oleum, chlorsulphonic acid or metal chloride melts and where the starting material has been prepared by condensation with such an acid medium, halogenation may be effected without isolation of the product.  In some cases chlorsulphonic acid may act as halogenating agent itself. Suitable catalysts are iron, iron chloride, mercury, antimony, iodine, and sulphur.  The products dye various shades of red which differ both in shade and fastness from those halogenated derivatives prepared by halogenation in organic diluents (see Specifications 7923/10 and 22780/10, [both in Class 2 (iii), Dyes &c.]).  Examples describe the chlorination of anthraquinone-2.1-benzacridone and the following derivatives thereof: Bz3-methyl and Bz3.5-dimethyl- (prepared by condensing 1-chloranthraquinone-2-carboxylic acid with p-toluidine and m-xylidine respectively, followed by ring-closure); Bz3-alkoxy- (prepared by condensing 1-chloranthraquinone-2-carboxylic acid with p-alkoxyanilines and ring-closure); Bz3-chloro-, Bz5-chloro-, Bz2- and Bz4-chloro- (prepared by condensing 1-chloranthraquinone-2-carboxylic acid with p-chloraniline, o-chloraniline, and m-chloraniline respectively and ring-closure of the products, followed in the last case by separation of the two isomers formed, either by fractional crystallization or by way of their oxonium salts); Bz3.5-dichloro-(example 1 of Specification 346,676); Bz2.3-di-chloro-, Bz2.4-dichloro- (prepared by condensing 1-chloranthraquinone-2-carboxylic acid with 3.4-dichloraniline and 3.5-dichloraniline respectively, and ring-closure); 4-Bz3.5-trichloro- (prepared by chlorinating the acridone in trichlorobenzene); Bz2.3.4-trichloro- (prepared by condensing 1-chloranthraquinone-2-carboxylic acid with 3.4.5-trichloraniline and ring-closure); 4-nitro-Bz3.5-di-chloro- (prepared by nitrating Bz2.4-dichloranilidoanthraquinone-2-carboxylic acid in nitrobenzene followed by ring-closure); Bz3-nitro (prepared by condensing 1-chloranthraquinone-2-carboxylic acid with p-nitraniline and ring-closure); the bromination of some of these compounds is also described and also the chlorination and bromination of anthraquinone-2.1 : 6.5-dibenzacridone.  The products derived from Bz3.5-dihalogen-derivatives are stated to be particularly valuable. Specification 338,216, [Class 2 (iii), Dyes &c.], also is referred to.

IPC: G01S1/02
Filed: 1965-08-03
Abstract: 1303622 Direction finding GERMANY MINISTER OF DEFENCE 3 Aug 1965 [22 Aug 1964] 33255/65 Heading H4D In a radio (or acoustic) direction finding system, the receiver is provided with several aerials having different polar diagrams, the outputs of which supply a cross-correlation device for interference suppression. The system is adapted to deal with signals of equal transit time from the transmitter and has dimensions which are small in comparison with the signal wavelength. A straight line trace is produced on a CRT screen, the angle of inclination of which is the azimuthal position of the transmitter. The outputs from the cross-correlation device are applied by synchronously operated switches to groups of storage elements which supply the CRT deflecting voltages. The storage elements receive correlation signals sequentially as the reception time progressively increases. This gives series of instantaneous deflecting voltages which form a linear series of spots on the CRT screen. For receivers with circular and figure-of-eight directional patterns, pressure or pressure gradient microphones may be used for air-conducted sound, hydrophones for underwater sounds and antennµ or frame antennµ for electromagnetic signals.

Abstract: 1,023,457. Exposure control in still or motion picture cameras. EASTMAN KODAK CO. Sept. 3, 1962 [Sept. 2, 1961], No. 33657/62. Heading G2A. To make allowance for film speed in the control of camera exposure by use of an exposure meter built into the camera and coupled through a friction coupling to an exposure regulating member, a holding means is engageable to over-ride the friction coupling and allow independent adjustment of the exposure regulating member to take account of film speed, the holding means being resiliently disengageable on movement of the exposure regulating member during such adjustment to an extent outside the range of film speeds provided for. As shown, movement of the exposure regulating member (shutter speed or diaphragm aperture setting member) drives via cable 1, drum 2 and gears 3, 4 shaft 5 on which index disc 6 is keyed and which drives through a friction clutch formed by spring washer 9 a gear 8 to which a film speed scale disc 7 is pinned. The gear 8 engages a gear 10 pinned to a plate 15 which bears a cam groove 19 embracing a pin 20 on the follow-up pointer 21 for the needle 22 of a photo-electric exposure meter 11 and also has a peripheral cam 23 which via a follower 24 closes contacts 25, 26 at low illumination levels to light a signal lamp or prepare for flash exposures. On depressing a button 13, the projection turned down from the end 12a of a member 12 engages the teeth of gear 10 and arrests it, so causing the spring washer to slip. Operation of the exposure regulating member then adjusts the system to take account of film speed as indicated by the index and scale discs 6, 7. When either of the limit of the film speed setting range available is reached, co-operating stops cause the discs 6, 7 to rotate together, whereupon due to the resilience of the outer end of the member 12 the projection at the end cams out of engagement with the teeth of gear 10 to avoid damage or incorrect setting of the device.

IPC: H01P1/365
Filed: 1957-10-31
Abstract: 843,847. Waveguide resonance isolators. MULLARD Ltd. June 6, 1958 [Oct. 13, 1957], No. 34028/57. Class 40(8). The band-width of a transversefield resonance isolator is improved by using elongated ferrite elements having cross-sections designed to provide a non-uniform magnetic field within the element. The crosssections are in the form of a circular arc or circular annulus intersected by a chord, the chordal surface of the element preferably being positioned against the waveguide wall. As shown, two part-annular ferrite elements F are positioned against the wide walls of a rectangular waveguide W and subjected to a transverse magnetic field provided by a magnet having poles M. The interiors of the annuli may be filled with brass to promote cooling. The improvement in band-width is a consequence of the dependence of the resonance frequency upon the magnetic intensity. Several examples of suitable elements, together with dimensions, are given in the Specification.
