Title: Method and apparatus for making electrical condensers
IPC: H01G13/00
Filed: 1925-07-01
Abstract: 236,559. Dubilier Condenser Co. (1925), Ltd., (Assignees of Vawter, C. E.). July 1, 1924, [Convention date]. Electric fittings.-The steps in the manufacture of small value fixed electric condensers are as follows :-Round brass tubing 2, Fig. 1, cut into lengths is deformed between convex dies 22, while being supported by spring side supports 3, into an elongated casing 1, Fig. 3. Within this casing are placed the condenser elements. A support 9, on which the condenser is assembled, is placed on a die 18, Fig. 9, resiliently supported by an adjustable spring 19, and the casing 1 is subjected to a blow from a die 17 so as to substantially fiatten it to the shape shown in Fig. 10, whereupon the casing tightly grips the condenser elements. The spring 19 ensures that the magnitude of the blow is approximately constant, even though the thickness of the assembled condensers vary slightly from one condenser to another, and thus ensures that the casings are always deformed sufficiently without the risk of fracturing the insulation. Specification 198,355, [Class 38 (ii). Electric currents, Converting &c.], is referred to.

Abstract: 403,381. Vehicle luggage carriers. SAFFELL, L. G., Taymount Cottage, Queens Road, Forest Hill, London. June 16, 1932, No. 17087. [Class 103 (ii).] A luggage-carrier for motor-cars &c. comprises a base member and an additional adjustable member or members which, when not in use, are adapted to be folded flat with the base member and which for securing luggage on the carrier are first coarsely and rapidly adjusted by one means in accordance with the size of the luggage and are then firmly pressed by screw or like means independent of the first means to secure the luggage effectively. In one form, Fig. 1, the carrier comprises an internallyslotted and toothed bar 1 rigidly secured to a rear part 4 of the car, an upper grid 8 having end projections 10 for engaging the teeth 3 of the bar, and bars 13 adjustably secured to the grid 8 and having teeth 14 engaging projections 15 on a lower grid 6 pivoted at 19 to the bar 1. When luggage 17 has been placed on the grid 6 the projections 10 and 15 engage teeth 3 and 14 and the grid 8 is pressed on the luggage by wing-nuts 16 on bars 13. To fold the device, the bars 13, which are offset, are first rotated to engage a projection on the grid 8, the inner end of which is then lowered to the bottom of the slot 2 in the bar 1, and finally the grid 6 is raised, the whole device being secured for example by a bolt and nut 21 pivotally attached to the bar 1. The grid 8 may be curved and may consist of flexible steel, leather, fibre, &c. To permit the grid 8 to be completely removed from the car, each bar 1 may have the rear portion forming one side of the slot 3 cut away, while to permit the entire carrier to be removed the bars 1 may be pivotally mounted on the grid 6. The toothed bars 1, 13 may be replaced by springs removably or otherwise secured to the grid 8 and to the grid 6 and having tightening-means. In a modification,. Fig. 5, applied to a known type of carrier comprising pivotally-connected grids 30, 31, bars 37 carrying plates 38 are pivoted to members 33 secured to L-shaped guiding-members 34 which slide in fixed U-shaped members 32. When the members 33 have been fixed in position by wing-nuts 36 and screws 35, the plates 38 are pressed against the luggage by a nut and screw 39, 40. The parts collapse to the position shown dotted.

Filed: 1929-06-05
Abstract: 333,670. Etridge, J. J., and ImperiaL Chemical Industries, Ltd. June 5, 1929. Catalytic materials and processes.-Catalysts. for the oxidation of sulphur dioxide or other oxidation reactions comprising stannic hydroxide gels are obtained by delayed precipitation of a solution containing a stannic salt with ammonia, as by adding the ammonia gradually and with constant stirring. Catalytic oxides may be incorporated with the gel ether by co-precipitation, or by adsorption of salts of the oxides, for instance of cobalt nitrate. By pouring a solution of ammonium vanadate into the stannic hydroxide sol before gelation, a product containing vanadium oxide is obtained. The gels, after washing and shaping, are dried for five days at 250‹ C., for two days at 120‹ C., and then activated by heating to 600‹ C.

Title: Improvements in or relating to radars

Filed: 1965-04-23
Abstract: 1,037,000. Pulse radar. TELEFUNKEN PATENTVERWERTUNGSGESELLSCHAFT. April 23, 1965 [June 25, 1964], No. 17314/65. Heading H4D. In a pulse (MTI) radar, I.F. echo signals are fed into two paths, one containing a phase shifter 9, able to introduce a variable phase shift of between 0 and 45 degrees, and the other containing a similar phase shifter 10, and a delay, having a delay approximately equal to the pulse repetition period of the radar transmitter 3. The two paths feed the two inputs of a phase discriminator 11, which passes its output, representing the difference in phase between signals in the two paths, to the two phase shifters, via D.C. amplifier 12 and switch 13. The output varies the phase shifts of the two phase shifters in opposite directions by equal amounts, until the output becomes zero. The switch is opened only during the transmission of the radar pulses, such that, as received at the phase discriminator inputs, consecutive transmitted pulses are coherent, with the result that echoes from these pulses are also received at the phase discriminator inputs, coherently if they originate from stationary targets, but non-coherently if they originate from moving targets. The phase discriminator thus only gives a video output in response to echoes from moving targets. The variable phase shifters may comprise capacitive diodes, Fig. 2 (not shown), having their capacitance varied by the output of the phase discriminators appearing across a capacitor having a very quick charge-up period and low leakage. The capacitor is discharged prior to the ensuing transmission pulse.

Abstract: 1,069,324. Photo-mechanical printing plates. GEVAERT PHOTO-PRODUCTION N. V. April 27, 1964 [April 26, 1963], No. 17330/64. Heading G2M. Offset printing plates are produced by treating a hydrophilic metal layer bearing a silver image with a solution of an organic compound containing an oleophilic radical ionized in solution and capable of reacting with the metal layer to produce a hydrophobic water-insoluble compound and then removing the silver image. The silver image is generally produced by the silver salt diffusion transfer process but it may be produced by selectively etching a silver layer on a hydrophilic metal layer, the silver areas which are not to be etched being shielded during etching. Aluminium and zinc are specified as the hydrophilic metals. The organic compound may be an anionic or amphoteric wetting agent or a fatty acid or a salt thereof. In the examples, a silver image, produced by the diffusion transfer process, on an aluminium or zinc foil is treated with an aqueous solution of sodium myristate, stearate or 10-sulpho-oleate, ethyl lauryl orthophosphate, laurylbenzene sodium sulphonate or a mixture of N-stearyl-and N-arachidoyl-methylaminoacetic acid and the silver image is then removed with a solution of ferricyanide, permanganate, dichromate, peroxydisulphate, iodide with iodine or ferric salt of E.D.T.A. The first solution may contain a thickening agent or be non aqueous e.g. stearic acid in glycerine/ethanol.
