Title: Multiple circuit electrical switching devices employing perforated cards
IPC: G01R31/25
Filed: 1951-06-05
Abstract: 696,786. Stencil switches. PERDIJON, E. June 5, 1951 No. 13280/51. Class 38 (v) [Also in Groups XIX and XXXVI] A switch employing perforated cards each corresponding to a different combination of a plurality of circuits, for, e.g., the testing of radio valves, comprises a number of insulating plates 3<SP>1</SP>, 3<SP>11</SP>, 3, 4, 7, 8, 9 having axially-aligned holes in which contact rods 2 may slide, each rod corresponding to one circuit. Plates 3, 3<SP>1</SP> carry sockets contact 1, 1<SP>1</SP> in alignment with the holes whereby a circuit is completed whenever a rod 2 is moved to connect its respective pair of contacts 1, 1<SP>1</SP>. Plates 3<SP>1</SP>, 3<SP>11</SP>, 3, 4, are connected together in spaced relalationship by screws 5 and spacer 6 to form a unit which is fixed by the screws 5 within a casing 17. Similarly, plates 7, 8, 9, form another unit with the screws 10 and spaces 11, and are fixed within a casing 18. Marginal plate section 13 form a gap between the plates 8, 9, in which a perforated card 14 may be inserted, the holes in the card being in line with those in the plates. The rods 2 are of such length that when collars 12 thereon abut the plate 7 the corresponding end enters a respective hole in the plate 8 but does not protrude beyond the latter, the opposite end of the rods being adjacent the entries of the socket contacts 1. In use, a card 14 is inserted in a slot 19 in the casing 18, and the two casings 17, 18, are moved towards each other. The rods 2 thereby abut the contacts 1, and if their opposite ends are not adjacent a hole in the card 14, are pushed by the card through the sockets 1 into engagement with the sockets1<SP>1</SP>, the other rods being pushed by the contacts 1 through holes in the card, hence a circuit is completed by each rod which does not pass through the card. On separation of the casings 17, 18, the collars 12 of the engaged rods abut the plate 7 and are thereby withdrawn from the sockets 1, 1<SP>1</SP>, whilst gravity action produces return of the remaining rods. To prevent incorrect insertion of a card 14, asymmetrically disposed rods 15 are fixed to the plate 4 and co-operate with additional openings 16 in the card. The casing 17 may be rectilinearly guided within the casing 18 by pairs of linkages 21, 22, 23, Fig. 2, links 21, 22, being pivoted to the casing 18, and the midpoint 24 of the links 23 being pivoted to the casing 17. The casing 17 is moved by a handle 25 pivoted at 26 to the casing 18 and having an arm 20 connected to the casing 17 by a link 27. The linkages 21, 22, 23, may be provided on each face of the casings, and certain of the pairs of linkages may be connected by a link 35.

Patent GB-346587-A (GB)
Title: Improvements relating to welding rods for use in electric arc welding
IPC: B23K35/02
Filed: 1930-05-01
Abstract: 346,587. Uniting by fusion. QUASIARC CO., Ltd. and STROHMENGER, A. P., 15, Grosvenor Gardens, London. May 1, 1930, No. 13461. [Class 83 (iv).] Metallic-arc welding electrodes are made by drawing out a composite billet consisting of a core of an alloy steel containing a relatively high proportion of chromium, nickel, manganese, or the like and a sheath of mild steel so as to deposit the required alloy steel without overheating the electrode, such as would occur if equivalent rods of alloy steel of uniform composition throughout were used, due to the high resistance thereof. The billet may be made by casting the mild steel on a core of the alloy steel. The higher conductivity of the sheath renders the operation of the arc more effective and the higher fusing temperature thereof causes the formation of a cup at the end of the rod. A composite billet may be formed by casting mild steel in a mould 14 inches square round a core 6 inches in diameter of steel containing 12 per cent of manganese and reducing to obtain a wire of No. 10 S.W.G. which may be used in place of a wire of uniform composition of the same size containing 3 per cent of manganese. The rod may be coated with slag-forming material, preferably a spiral winding of blue asbestos yarn.

Patent GB-477139-A (GB)
Title: Improvements in and relating to the detection of faults in solid, liquid or gaseous bodies
IPC: G01N29/06
Filed: 1937-05-13
Abstract: 477,139. Measuring intensity of sounds. SOKOLOFF, S. May 13, 1937, No. 13509. [Class 118 (ii)] [Also in Group XIX] Comprises a process for detecting faulty places in solid, liquid, or gaseous bodies by ultra acoustic oscillations produced by piezo-electric means and directed through the body which oscillations on emerging from the body excite a piezo-electric crystal plate to produce a potential difference characterized in that the distribution of electric charges on the plate is analysed by known television means and transformed into a visible or graphic picture by television reception. The body 1 with faults 5 to be detected has bearing against it a quartz plate 2 excited by a high frequency generator 6. The ultra-acoustic rays 4 traverse the material except where cut off by the faults 5 and in turn excite a quartz plate 3 producing a non-uniform distribution of electric charges on the plate. Bearing against the plate which on this side is wetted with oil is a Braun tube 7. The side of the plate 3 next the body is coated with finely powdered metal. The inner or outer surface of the Braun tube is covered with a network of fine electrodes 8 insulated from one another similar to the light-sensitive mosaic in the television system of Zworykin. The charges of the individual electrodes at the end of the tube can be taken off by a thin electron pencil 9. If the pencil 9 be deflected in the usual way in two directions at right-angles, the distribution of the charges can be transmitted to the receiving device proper in the form of a cathode tube with a phosphorescent screen. In a further construction, at the inner end surface of the Braun tube a light sensitive mosaic is distributed, a network of fine electrodes being applied to the piezo-electric mosaic lying at the same time against the outer surface. The fine electrodes receive the charges which control the electrons emanating from the photo-mosaic. Again, the quartz plate or the body may be moved in two directions at right-angles and the intensity of the piezo-electric charge fixed in each point. In this case the quartz receiver is as small as possible.

Title: A process for recovering hydrazine from aqueous solutions
IPC: C01B21/16
Filed: 1957-04-29
Abstract: A process for the recovery of hydrazine from an aqueous solution, especially one containing substantially 1 per cent by weight of hydrazine, comprises mixing the solution with cyclohexanone, and splitting the precipitated dicyclohexylidene hydrazine by an acid into cyclohexanone and the corresponding hydrazine salt from which hydrazine may be liberated preferably by alkali metal hydroxide.  By working in neutral solution and using 5-70 per cent excess cyclohexanone the precipitation may be made quantitative; salting out is advisable using 3-20 per cent by weight of separating agent based on the weight of liquid.  The dicyclohexylidene hydrazine may be separated in liquid (above about 35 DEG  C.) or solid form.  The separation may be effected continuously.  The acid splitting may be effected by steam distillation with one mol. of H2SO4 for each 2 mols. of hydrazine produced, preferably in the absence of air, e.g. in a protective gas or steam atmosphere.  An example is given.ALSO:Dicyclohexylidene hydrazine is formed by adding cyclohexanone to an aqueous solution of hydrazine, e.g. one containing substantially 1 per cent by weight of hydrazine.  By working in neutral solution complete precipitation occurs, and separation may be made quantitative by using a small excess, e.g. 5-20 per cent of cyclohexanone.  It is advisable to complete the precipitation by salting out using a separating agent in an amount of from 3-20 per cent by weight based on the weight of liquid.  The dicyclohexylidene hydrazine may be separated as a liquid (above about 35 DEG  C.) or as a solid.  The process may be continuous.  The preparation forms a step in a process for purifying hydrazine (see Group III).  An example describes the preparation of dicyclohexylidene hydrazine by adding cyclohexanone to a 1 per cent aqueous solution of hydrazine hydrate.

Title: Improvements in or relating to thermonuclear plasma apparatus
Inventor: PREVOT FRANCOIS
IPC: H05H1/22
Filed: 1960-04-19
Abstract: 913,469. Ion sources. COMMISSARIAT A L'ENERGIE ATOMIQUE. April 19, 1960 [April 20, 1959], No. 13651/60. Class 39 (1). A thermonuclear plasma device consists of an annular ion source 18 and an annular accelerating electrode 19 for injecting the ion beam in sheet form into the plasma chamber 4, the plasma confining coils 5, 6 being so arranged that the ions pass successively through two regions of opposite magnetic polarity and so that the magnetic flux is substantially zero at the ion source. The plasma confining magnetic coils 5, 6 provide a field of axial symmetry in the region of injection and are surrounded by a ferromagnetic frame 26 which is provided with an annular gap 27 for the passage of the ion beam. An auxiliary accelerating electrode 33 is supported by the ferromagnetic frame 26. The plasma is generated within the chamber 4 by an arc discharge between electrodes 11 and 12. Cooling channels are provided for the plasma chamber and for the magnetic coils. The ion source 18 and accelerating electrode 19 are supported by a plurality of insulators 20. The ion source emits molecular ions which are dissociated into atomic ions in the plasma. The ion source accelerating voltage may be given a saw-tooth waveform in order to turn back ions which pass through the plasma without being dissociated. Alternatively, the ions may be injected as a conical beam at an angle to the axis of symmetry of the system. The ions are injected into a weak part of the magnetic field and move into a region where the field is relatively strong. The zones of weak and strong magnetic field may be obtained by the use of magnetic shunts or by providing extra magnetic coils which produce a reverse magnetic field over a part of the confining magnetic field region. The conical ion beam may be obtained by displacement of the insulators supporting the ion source and the accelerating electrode or the supporting electrical connections within the insulators or the ion source elements may be suitably located to form the conical sheet beam. In another embodiment, Fig. 10, the annular ion source 49 is associated with a distributed system of accelerating electrodes 50. The ion source may be, e.g. a high-frequency source or an arc source.
