Title: Electrostatic filtering apparatus
IPC: A01G25/09
Filed: 1964-12-01
Abstract: In an electrostatic precipitator, dust-laden gas is saturated with the vapour of a liquid and supersaturated with a fog of fine droplets of the liquid by means of spraying devices 3 and is submitted, on entering a Venturi tube 4-5 to a sudden expansion (i.e. in the neck portion 4) which lowers its temperature to such an extent that the vapour carried by the gas condenses on the dust particles in the form of a superficial liquid film, and the wet particles are thereafter ionized by a central ionizing electrode 8, Fig. 1, or 13, Fig. 2 (not shown), the gas being whirled at a high speed in the diverging portion 5 of the Venturi tube by means of helicoidal vanes 11 in order to urge the liquid droplets and the wet particles from the central zone which surrounds the ionizing electrode towards the wall of the Venturi tube. By this construction, the amount of moisture is reduced around the ionizing electrode and arcing between the electrode and the wall of the Venturi tube is minimized so that a relatively high voltage may be employed and electrostatic separation improved. In Fig. 1, the electrode 8 is pointed and extends into the Venturi tube. The cleaned gas leaves at 9 and the liquid and separated particles are extracted via an air lock or valve at 10. In Fig. 2 (not shown) a further Venturi tube 12 is provided below the tube 5 and the ionizing electrode 13 is in the form of a conical network and is mounted within the tube 12. The tube 12 opens into a collecting chamber 15 in which are mounted a liquid sprayer 16 and precipitating surfaces 17.

Title: Infrared sensing by quenching in junction semiconductor
IPC: H01L31/06
Filed: 1965-02-10
Abstract: A detector for long wavelength radiation comprises a PN junction in a semi-conductor body in which minority carries generated by radiation of a shorter wavelength can have their lifeline reduced by said long wavelength radiation associated with a source or the shorter wavelength radiation. Preferably the minority carries are generated in the P-type material which includes accepted levels which are filled in response to the longer wavelength radiation. In a preferred arrangement the body consists of copper doped P-type gallium phosphide with a PN junction forming contact of tin and ohmic contact of gold-zinc alloy alloyed to it side-by-side. The doping is chosen so that the Fermi level lies below the copper acceptor levels. The radiation source is identical except that the P-type body is doped with zinc instead of copper and is included in the same housing which has an aperture to admit infra-red radiation. As an alternative the radiation sensitive body consists of a layer of oxygen doped N-type gallium phosphide epitaxially deposited on a copper-doped P-type body and the radiation source comprises a junction formed by diffusig zinc into N'type gallium phosphide. It is also possible to form the sensitive junction and radiation source in a single body by diffusing copper and zinc respectively into opposite faces of an N-type oxygen doped gallium phosphide body.

Title: Method of producing rail sections
IPC: B21B31/14
Filed: 1965-04-10
Abstract: A method of producing a rail comprises applying rolling forces in a series of passes to the upper and lower surfaces of the rail head while leaving the side surfaces free (see Fig. 3, not shown), and applying further rolling forces in a series of passes interposed with those of the first series to the side surfaces and the lower surfaces of the rail head while leaving the upper surface free (see Fig. 4, not shown). The blank is maintained symmetrical during the steps as distinct from known methods in which the blank passes through the shapes a, b, c, Fig. 1 (not shown). Fig. 2 (not shown) illustrates the corresponding stages achieved in the present method. The rail is cold-rolled. The base of the rail is formed by a roll 221, Fig. 5 (not shown). Before the blank approaches the series of forming mills it is passed four times through a reversing blanking mill 28, Fig. 21 (not shown), and then through a blank finishing mill 31. The top rolling mills 32 are driven by variable-speed D.C. motors, but the mills 33 are not driven. The final mill 34 rolls the rail to its final shape, Fig. 13 (not shown), and has rolls 35, 36, Fig. 23 (not shown), co-operating with a roll 37. When the rolls are worn, the mill is turned through 180 degrees and other parts of the rolls 35, 36 are used. In a modification, only two mills are used to shape the rail, several passes being made through each of them. The rolls 22, Fig. 26 (not shown), forming the top and under surfaces of the rail, have to be displaced by different amounts during passes to ensure even working of the metal.

Title: Methods for Feeding Liquid Metal in Continuous Centrifugal Casting, and Apparatus for Carrying Out the Methods.
IPC: B22D11/10
Filed: 1967-05-30
Abstract: In a method for the uninterrupted supply of molten metal to continuous centrifugal casting apparatus, a rotating mould 1 is alternately supplied with molten metal from a first feeding device 4 whilst a second feeding device 41 is inoperative, and vice versa, whereby the mould is provided with a continuous uninterrupted supply of metal by the successive operation of the feeding devices. The feeding devices 4, 41, are formed of refractory material and are shaped to supply a jet 3 or 31 of molten metal respectively which impinges obliquely on the surfaces of the metal in the rotating mould. The alternate use of the devices permits one of them to be repaired whilst the other is in use. In an alternative embodiment, two moulds 1, 1 are supplied from furnaces 7, 71 by way of channels 8 and 81, each furnace supplying one feed device to each mould.

Title: Cargo loading device
IPC: B66C23/60
Filed: 1967-06-10
Abstract: In a ship's derrick having a boom 3, Fig. 1, which can be swung over between a pair of posts 2 by span tackles 9, an upper load block 16 is supported by a swivel 18 from a pendant 17 mounted at one side of the boom on a transverse head-pin 5. When the boom is swung over the upper block 16 is rotated on the swivel 18 by a lug 20, Fig. 3, on the boom which cooperates with a pair of oppositely directed lugs 19 on the block. So that the parts 21, 22 of the hoisting cable do not rub against each other the pulleys in the block 16 are arranged one above the other and the top pulley is larger than the bottom one. This also avoids loading the block eccentrically.
Patent ES-347560-A1 (ES)
Title: A Process for Producing Methanol.
IPC: C07C29/159
Filed: 1967-11-24
Abstract: Methanol is produced from synthesis gas which contains carbon monoxide, hydrogen and up to 10% by volume of CO 2 , with the aid of a methanol synthesis catalyst, under superatmospheric pressure and at an elevated temperature, and wherein dimethyl ether formed as a byproduct in the process is distilled from the liquid reaction product and is recirculated into the process. Water may be added to the dimethyl ether-containing gas which is recirculated to the process, especially when the synthesis gas has a carbon dioxide content less than 0À2% by volume. In this way a higher conversion of carbon monoxide and hydrogen to methanol and a reduction of synthesis gas losses due to the formation of dimethyl ether are obtained.

Patent ES-391053-A1 (ES)
Title: Striking mechanisms for clocks
IPC: G04C21/10
Filed: 1971-05-11
Abstract: A clock striking mechanism includes a counting wheel having peripheral notches spaced by amounts which differ and related to the number of strikes at each striking action, a gear wheel fast with the counting wheel and meshing with a worm. A cam driven by the minute spindle of the clock movement raises a lever when the hour or half-hour is to be struck and a projection on the lever is raised thus leaving the counting wheel free to rotate. The worm is mounted on a spindle which is arranged to open and close a pair of contacts in a supply circuit of a motor and release of the counting wheel frees the worm and its spindle to close the contacts under the bias of a spring. The motor is energized and rotates the spindle to actuate striking mechanism by means of a cam or cams mounted on the spindle. The worm simultaneously drives the gear wheel and hence the counting wheel and striking ceases when the next notch is reached and the lever projection engages therein.
