VSESOJUZNY NAUCHNOISSLEDOVATELSKY INSTITUT OBORUDOVANIA DLYA PECHATNYKH IZDANY, KARTONNOI I BUMAZHNOI TARY and SPETSIALNOE KONSTRUKTORSKOE BJURO POLIGRAFICHESKOGO MASHINOSTROENIA. April 30, 1969, No.21927/69. Heading G2M. Apparatus for use in hardening the resist layer overlying a printing plate blank prior to etching in the production of a printing block comprises two vessels containing molten salt and coolant respectively, means for transporting the plate between the vessels, and a device for dropping the plate into the coolant vessel, the dropping device being actuated by the transporting means. A housing 1, Fig.1, contains two vessels, vessel 2 being filled with a molten salt and vessel 3 with a liquid coolant. A holder 9 for a printing plate blank is rigidly connected to a two-arm lever 8 mounted in a hollow bracket 7 which is fixed to a cross-bar 6 reciprocable along a guideway to under the action of a bear screw 5; the opposite end of the two-arm lever 8 from holder 9 to pivotally connected to a rod 10 slidable within the bracket 7 and arranged to co-operate with a limiting stop 11. In use, a plate blank bearing a resist is mounted in holder 9 so that its bottom edge rests on a support member 13; drive 17 is set into motion to advance the lead screw 5 and cross-bar 6 downwards. When the end of rod 10 engages the stop to the arm 8 and holder 9 anti-clockwise, as seen in Fig. 1, so that the holder becomes nearly vertical. Further rotation of the lead screw 5 drives the holder and plate down into reverse 2. After a pre-determined time, the drive is re-commenced in the opposite sense, and the holder is raised until a head-piece 19 on rod 10 engages the stop 11 to discontinue the lifting; continued movement of screw 5 causes the holder 9, under the action of two-armed lever 8, to pivot clockwise, and take up a position over vessel 3. During this latter movement, a member (14), Fig. 4 (not shown) strikes a fixed abutment 16, and causes support member 13 to pivot and allow the printing plate blank to drop into the coolant.

Abstract: 1311385 Artificial teeth Y SIMONPAOLI 19 April 1971 [10 Feb 1970 28 Jan 1971] 22168/71 Heading A5R An artificial denture is manufactured by providing a moulded metal core 10 provided with keying depressions 14 at its upper surface, degreasing the surface of the metal core, and then subjecting the core to thermal degassing treatment, coating the upper surface of the core with a bonding agent 16, thermally treating the bonding agent, and then applying over the bonding agent one or more coats of a ceramic material which are fired. The metal core is a nickel-chromium alloy also containing carbon, manganese, iron and boron, and the keying depressions are formed by a slotted milling cutter mounted on a turbine. The surface of the metal is degreased by immersing the core in a bath of hydrofluoric acid, and the core is degassed by firing it in a kiln at 700‹C. The bonding agent consists of a suspension of an oxidising agent such as white tin oxide or potassium oxide in a liquid, and the thermal treatment of the bonding agent comprises heating it in a kiln from 700‹C to 1050‹C in vacuo. A ceramic coating 18 is applied to the surface of the bonding agent by sprinkling ceramic material on to the surface and firing, preferably in vacuo in a conventional manner. Further ceramic coats are then similarly applied, the total number of coats not exceeding five. The layers of bonding material and ceramic material are supported on a shoulder 12 on either the metal core or the dental preparation in which the core is inserted.

Abstract: 1460245 Yarn advancing nozzles BARMAG BARMER MASCHINENFABRIK AG 4 July 1974 [4 July 1973 (2) 9 May 1974] 22177/75 Divided out of 1442924 Heading D1F In a pneumatic device for delivering or advancing a fibre bundle e.g. yarn or continuous filament tow, at speeds which may exceed 3000 metres per minute, the bundle 1 emerging from the nip between fixed and rockable spring-loaded rollers 2 and 3 is propelled through a channel 13 of a nozzle 7 by compressed air streams supplied through a conduit 8, an annular channel 9 and a series of radial channels (or another or similar channel, not shown) terminating in openings 10 and inclined in the direction of delivery. Air suction induced through the gap between rollers 2 and 3 and between nozzle flanks 11 and 12 ensure that the bundle or individual filaments are not caught by a layer of air on the roller surfaces. Channel 13 opens into a frusto-conical portion 15 which slows the main air stream to prevent turbulence and confine the filaments of the bundle therewithin. A slot 16 extending the entire length of channel 13 enables the bundle to be inserted while it is in motion. The nozzle is mounted in guide rails 32, 34 whereby, in the event of a snag occurring e.g. on roller 2, during abnormal operating conditions, the holding action of a spring-loaded positioning device 33 is overcome and the nozzle escapes in the direction of delivery. As shown in the nozzle of Fig. 3, a series of additional jets from channels 17, 18, and inclined top channels 19, 20 open along the length and on both sides of the slot 16 to prevent escape of filaments from channel 13. In another nozzle, Fig. 5 (not shown) slots extending over flanks 11, 12 and communicating with channel 9 through additional channels (21, 22) direct air onto the surfaces of rollers 2, 3, against the direction of rotation thereof.

Title: Improvements in or relating to fertilisers
IPC: C05D9/00
Filed: 1954-07-29
Abstract: Water soluble fertilizing materials and/or trace elements are incorporated in a highly porous carrier material which is a mixture of diatomaceous earth with calcined diatomaceous earth, plastic clay or fuller's earth.  Trace elements specified are iodine, manganese, copper, iron, zinc, magnesium, cobalt, boron and bromine.  The fertilizer or trace elements compounds may be incorporated in the carrier either by providing a saturated solution of the compounds to be incorporated and introducing dry carrier material thereinto and subjecting the suspension to alternating pressure and rarification. Sodium or potassium silicate or glues such as casein may be added to decrease the solution rate of the fertilizer.  The suspension may then be sprayed under pressure into a quantity of the same carrier material in a dry pulverized state in a mixing machine. Alternatively the carrier material may be broken down mechanically in a mill and the fertilizing compounds added partly in solid form and partly in solution in the mill.  The plastic mixture may then be fed to an extrusion pressure to provide granules having a length of 1/4 in. to 1/2 in. and a diameter of about 3/4 in.  The granules so obtained are dried to about 10 per cent moisture content.  Examples refer to carrier material in the form of a mixture of diatomaceous clay, with calcined diatomaccous clay and fuller's earth with diatomite. In such carriers are incorporated ammonium sulphate, potassium nitrate and chloride, and urea together with soluble compounds of trace elements.
