Title: Improvements in or relating to electric current converters
IPC: H02M1/28
Filed: 1946-03-01
Abstract: 608,901. Converting. WIDAKOWICH, M. March 1, 1946, No. 6502. [Class 38(ii)] A magnetically vibrated or oscillated rectifier, inverter or frequency changer is provided with one or more additional windings in the contact circuit normally having little effect but which will open the contacts in response to an abnormally large current through them. Fig. 1 shows an inverter wherein contacts 1a-2a and 1b-2b connect the D.C. source 5 alternately to the ends of the primary winding P of a transformer of which the secondary winding S supplies the A.C. load preferably through a series condenser 8 and with a shunt condenser 7. Windings 13a and 13b in series with the contacts have only a few turns, but such that on excessive current through the contacts-as, for example, when the contacts stick-they can exert sufficient force on the armature 3 to separate the contacts. These extra windings may be, as shown, on the operating magnets 10 which carry windings 14a and 14b fed with A.C. by the secondary winding S and vibrating armature 3 by assisting one and opposing the other alternately of the windings 12a and 12b supplied by source 5. In the modification shown in Fig. 2, the current in the secondary winding S is rectified by contacts 21a-22a and 21b-22b and used to charge condensers 11a, 11b and 25 from which is drawn a D.C. output. The operating coils 10a and 10b can be connected as shown or in either of the alternative positions indicated at X. The contacts 21a- 22a and 21b-22b can close later and open earlier than the other contacts, or vice versa.

Title: Improvements in haulage gear for slip-ways
IPC: B66D1/26
Filed: 1921-02-26
Abstract: 179,720. Glover, W. G. Feb. 26, 1921. Winches; driving-gear; brakes. - Haulage gear for slipways is constructed with the downhaul drum 7 on the same shaft as the main drum 1. The haulage rope passes from the main drum to the upper end of the cradle carrying the vessel, while the downhaul rope passes from the lower side of the cradle, round a pulley at the bottom of the slipway, to the downhaul drum. When the loaded cradle is being raised, the drum 7 is loose to pay out the downhaul rope freely, but when the vessel is to be launched, the drum 7 is clutched to the shaft by a friction or dog clutch 39. The driving motor 23 is reversed so that the drum 1 pays out, while the drum 7 supplies the initial force to start the cradle moving downwards. When the cradle is started, the drum 1 is disconnected from the motor so that it pays out under the load and drives drum 7 to take up the slack of the downhaul rope. To permit accurate winding and paying- out, the drum 7, using a thinner rope, is made slightly larger than the drum 1 so that the distance from the centre of each drum to the axis of the ropes is the same. The driving-gear includes sliding toothed wheels arranged for two lowspeeds, each speed being obtained by a train comprising four pairs of meshed wheels. A solenoid brake mechanism 30 is applied to the motor shaft, while brake blocks controlled by screw-operated linkages 35, 38 are applied to each drum. In a modified construction the drum 7 is cast in two halves and arranged between two drums 1 driven by separate motors so that It can be clutched to either drum shaft. The driving-gears can be cross-connected so that either or both motors can drive either drum 1, or either can drive the drum 7.

Abstract: 1419548 Bearings; seals HYDRO-JET CORP 9 Feb 1973 [10 Feb 1972] 6504/73 Headings F2A and F2B [Also in Division F1] A thrust bearing for a centrifugal pump shaft comprises a thrust disc 111, Fig. 2b, keyed at 113 to the shaft and located axially by a threaded cap 114 and an adjusting ring 117a which permit axial adjustment of the shaft and hence of the pump impeller. Six shoes 117 mounted on each side of the disc 111 carry buttons providing convex surfaces 119 which ride on pads 120 which are secured at 121 for limited movement within annular channels 122 of stationary discs 123. A mechanical seal 150, Fig. 2, at each end of the pump shaft comprises an annular insert 163 of tungsten carbide carried by the shaft and rubbing against a stationary carbon ring 166. The insert 163 is carried by an annular member 160 which is bolted at 159a to a sleeve 154 bolted at 157 to an end cap 157 which in turn is bolted at 156 to the shaft. O- rings 159, 161a and 164 are provided. Spring means 168 acts on the carbon ring 166 via a spacer ring 167a. Coolant, which may be tapped at 174 from the pump discharge, passes to the seal via an inlet 172. In a modification, Fig. 4 (not shown), the annular member (260) carrying the tungsten carbide insert (263) is integral with the sleeve (254). Friction at the axially slidable engagement between the tungsten carbide insert and the carbon ring and the respective support surfaces of their carriers is reduced by the interposition of rings (264, 271) of a low-friction synthetic polymer resin.

Title: Method for manufacturing molded articles
IPC: B28B3/00
Filed: 1966-02-16
Abstract: <PICT:1093205/C6-C7/1> Articles having at least one non-central bore therein are formed by isostatically pressing powdered material, e.g. ceramic or metal, in a resilient mould containing bore forming arbor(s), the arbor(s) being free to move with the powder during the compression.  In the example, arbors 16 are fixed relative to the mould during the filling by a cap 8 and end members 6 and 12, which cap and end members carry fins 14 and 10 which fit into the ends of the arbors. After the filling, the cap and end members together with the pins are removed and replaced by end-plates (25 and 26 Fig.3 not shown) against which the ends of the arbors slidingly abut.  The mould is then inserted in a pressure liquid and the powder is isostatically compacted, the arbors moving with the powder within the mould (see Fig.4 not shown).  The pressed article is subsequently released from the mould and fired to sinter if required, the arbors either being burnt out during the firing, or removed prior thereto. Instead of being slidable over end-plates the ends of the arbors may be sited in pads of material having similar compression characteristics to the working material.  Blind bores may be formed by using shorter arbors co-operating with one end of the mould only.

Filed: 1974-02-14
Abstract: 1429462 Use of polymer containing dye precursor groups BAYER AG 14 Feb 1974 [16 Feb 1973] 6768/74 Heading C3P [Also in Divisions D1 and G1] A method of identifying articles comprises marking with a polymer containing a group which can be released, e.g. by hydrolysis, giving a compound which can be converted into a dye, e.g. by diazotizing, if an amine, followed by coupling, or by coupling with a diazo compound if diazo-reactive and so forming a dye to identify the article. Examples relate to the use of copolymers containing as dye precursors (1) 3-methacryloylamino chlorobenzene, which on hydrolysis yields chloro-aniline identified by diazotizing and coupling with N-naphthyl-1- ethylenediamine hydrochloride to give a deep blue-red colour, (2) methacrylic acid-2,4-dichloroanilide which hydrolyses to 2,4-dichloroaniline and can be similarly identified giving a red-violet colour or (3) phenyl methacrylate from which phenol is obtained identified by coupling with diazotized sulphanilic acid giving a yellow colour. Qualitative identification may be made chromatographically, the chromatographic plate being sprayed with the appropriate coupling agent.

Title: Improvements in or relating to liquid coating compositions
IPC: C09D129/00
Filed: 1944-04-13
Abstract: Phenol-aldehyde resinous coating compositions comprise a suspension of finely divided particles of a normally solid fusible and soluble " A " stage resin in a mixture of a normally liquid resin and water or other liquid having a volatility not less than water, which particles have been produced at least in part by precipitation from solution in the mixture.  The compositions may be made by mixing a normally liquid resin and water or other liquid as defined above in proportions such that the normally solid resin is insoluble therein at room temperatures, incorporating the solid resin, or a thick liquid resin convertible to a solid resin on heating, heating the mixture to form a solution and finally cooling to form the suspension of finely-divided particles.  When a thick liquid resin is used in place of the solid resin, the mixture may be heated so as to advance at least a proportion of the thick liquid resin to the stage of a normally solid resin.  Alkali may be used to improve miscibility of the liquid resin with water.  In an example, a thin liquid phenol-aldehyde, e.g. phenol-formaldehyde resin is mixed with water and then with a finely pulverized " A " stage phenol aldehyde resin, and the stiff paste obtained is heated to dissolve at least part of the solid resin.  A further quantity of the mixture of liquid resin and water is then added, which causes partial cooling and precipitation of finely divided solid, and cooling is continued.  The mixture is then screened.  The compositions may be applied to a surface, e.g. paper, the water or other liquid removed, e.g. by allowing to evaporate, and the coated article heated.  They may be used as adhesives, e.g. in the manufacture of plywood, sandpaper, or laminated materials from sheets of paper or cloth or alternate sheets of cloth and paper or other felted materials.  The compositions may be applied at ordinary temperatures or at temperatures up to 140-150 DEG  C. Specification 462,697 is referred to.
