Title: Derivatives of the di-hydroxy-benzenes and process for the manufacture of same
IPC: C07F9/12
Filed: 1933-05-01
Abstract: Monoethers of dihydroxy benzenes in which the ether group is aryl, aralkyl or alkyl of more than four carbon atoms are boiled with phosphorus oxyhalides, the halides of the acid phosphoric esters produced are saponified with water, and the free esters converted into salts by neutralisation.  Catalysts such as phosphorus pentachloride and quinoline may be employed for the initial reaction. With excess of phosphorus oxyhalide, the monoester halide is obtained practically exclusively, otherwise the diester halide is also obtained.  Saponification of the ester halides with alkali yields ester acids of the type of pyrophosphoric.  The preparation of the monoester-acids is represented by the following equations:-- <FORM:0404520/IV/1> The products are suitable as internal disinfectants.  According to examples, (1) hydroquinone-monophenyl ether is boiled with phosphorus oxychloride, with or without phosphorus pentachloride, and the product distilled, hydrolysed with water and neutralised with sodium ethylate.  The calcium salt, which is difficultly soluble and obtained by precipitation, and the hexamethylenetetramine salt are referred to; (2) 1 hydroxy-2-chloro-4-phenoxybenzene is treated with phosphorus oxychloride and quinoline, the product distilled, hydrolysed and converted to the sodium salt; (3) pyrocatecholmono-phenyl-ether is treated with phosphorus oxychloride in presence of phosphorus pentachloride and quinoline, the product distilled, hydrolysed and the ammonium salt obtained; (4) hydroquinone monobenzylether is treated with phosphorus oxychloride in presence of phosphorus pentachloride, the product hydrolysed and extracted, purified and converted to ammonium salt; (5) hydroquinone monoisoamyl ether is treated with phosphorus oxychloride in presence of quinoline and phosphorus pentachloride, the product purified by fractionation, hydrolysed and converted to ammonium salt; (6) resorcinol monophenylethyl ether is treated with phosphorus oxychloride in presence of diethylaniline or phosphorus pentachloride and chloroform, and the product hydrolysed and converted to the sodium salt.  Specification 203,820, [Class 2 (iii), Dyes &c.], is referred to.

Title: Improvements in or relating to radar systems
Inventor: HANSFORD REGINALD FREDERICK
IPC: G01S7/28
Filed: 1955-05-02
Abstract: 786,661. Radar. DECCA RECORD CO., Ltd. April 30, 1956 [May 2, 1955], No. 12724/55. Class 40 (7). In a pulse radar with a main receiving aerial system connected to a main receiver and having a directional pattern 10 (continuous line), the effective width of the major lobe 11 and the effect of the sidelobes 12 and 13 are reduced by providing an auxiliary receiving aerial connected to an auxiliary receiver and having a directional pattern (dashed line) with at least one lobe, e.g. 14 and/or 15, offset from the major lobe 11, the video outputs from the two receivers being subtracted to give a difference signal having an effective directivity pattern 16 (dot-dash line) which is applied to the display unit. The shape of the pattern 16, and hence the extent of sidelobe suppression, may be varied by adjusting the relative amplitudes of the two video signals. For azimuth discrimination on a P.P.I. display, the auxiliary directivity pattern preferably comprises two symmetrical lobes 14, 15, as shown, which may be produced (1) by an array of primary elements whose outputs are added at the R.F., I.F. or video stage, or (2) by two separate aerial systems coupled to respective receivers whose video outputs are added. For elevation discrimination the auxiliary directivity pattern may comprise a single lobe at a lower elevation than that of the main lobe. In a long-range radar the video outputs from the main and auxiliary receivers are also added to give a summation signal, the difference signal being applied to the display during an initial portion of the range scan and the summation signal being applied during the subsequent portion of the range scan by means of gate circuits, Fig. 2 (not shown). The main receiving aerial is preferably used also for transmission and the aerials may comprise primary elements, e.g. horns, polyrods or waveguide slots, associated with a common or separate focusing element, e.g. lens or parabolic reflector. When separate focusing elements are used for the main and auxiliary aerials they may be arranged one above the other.

Title: Screens for colour photography
IPC: G03C7/08
Filed: 1925-05-16
Abstract: 244,644. Keller, H. May 16, 1925. Colour photography, screens for.-Screens for use in producing transparencies or pictures on paper supports are produced by spraying or dusting upon a colloid layer, for example gelatin or albumen, materials which dye the colloid only when it is in an unhardened state, and which themselves harden the colloid. Pinatype dyes, and most anilin dyes may be so employed. A substance such as formalin or chrome alum may be mixed with the dyestuff solution or powder, so that, a short time after application, the colloid is hardened at the points which have received dyestuff, and these are thereby rendered incapable of receiving other dyestuffs subsequently applied. After spraying or dusting on the requisite number of water-soluble colours, the screen is washed in water to remove surplus dyestuff, leaving a screen of coloured elements which do not overlap. When the dusting-on process is used, the colloid surface is preferably moistened.

Title: Improvements in or relating to shooting training devices comprising a dummy gun
Filed: 1942-09-12
Abstract: 562,130. Teaching shooting with machine guns. BAKANOWSKI, Z. DE LUBICZ-, and SUK, R. Sept. 12,'1942, No. 12878. [Class 119] A dummy machine gun comprises means whereby, on pulling the trigger, an electrical target-marking device, associated with a targetcarrying metal plate mounted on the gun, is energized intermittently so long as the trigger is held, to represent the firing of a series of shots. At the same time an impact member or members in the gun is, or are, actuated to produce vibrations and noise similar to those produced by actual firing. In the form shown in Figs. 9a, 9b, aim is taken at a target 407 on a target frame 378, fixed relatively to the gun mounting, and an electric needle 324 is projected forwards at each simulated discharge to make contact with a duplicate target 407a mounted on a metal plate 277 below the target 407. The needle and plate are in a high-tension electric circuit so that each time the needle makes contact with the target 407a a spark passes through the target and marks thereon the result of the shot. The needle 324 is carried by a lever-arm 322 pivoted at 323 on a bracket 319 mounted rigidly on the muzzle end of the barrel 201 of the dummy gun. A link 321 connects the arm 322 with the pivoted armature 320 of an electromagnet 316 which is energized intermittently through an interrupter in the gun driven by an electric motor 210 through a flexible shaft 211. A cam 328 on the bracket 319 operates through a rod 327 and bell-crank 325 to compensate for the different displacements of the needle relatively to the line of aim as the gun is elevated or depressed. In addition to driving the interrupter switch devices, the shaft 211 is connected to a cam-shaft which displaces spring-pressed weights within the gun and then releases them so that they fly back and jar the connection 345, 348 between the gun body and the elevating.screw, and also impact with a diaphragm in the body to simulate the noise of discharge. The motor circuit is initially closed by a switch 300 operated by a safety-slide 501, and the flexible shaft 211 is connected to the interrupter and cam-shaft within the gun by a clutch operated by the trigger 260 through links 260a, 259, 258. In a modification, a solenoid within the gun body is energized when the trigger is pulled, and its core provides the movable element of the interrupter switch as well as the impact member. In this case, the marking needle is located behind the aiming target coincident with the line of aim, and marks a recording target which is a mirror image of the aiming target. The metal target-carrying plate may be swung upwards about a horizontal hinge to enable aiming at real objects to be practised.
