Abstract: 1,087,146. Welding by fusion. SIEMENSSCHUCKERTWERKE A.G. June 1, 1965 [June 11, 1964], No. 23408/65. Addition to 1,016,896. Heading B3R. In arc weld surfacing in accordance with the invention of the parent specification 1,016,896, in which the electrode is oscillated transversely, the filler wire feed is stopped and restarted at different points in the path of oscillation. In depositing a weld bead 3 adjacent a previously deposited head 4, the filler wire 2 feed is stopped as the electrode approaches the joint between the beads and is restarted on the return movement before the electrode reaches the joint, i.e., while the overlapping portions of the beads are being welded. The idler roll 11 of a pair of feed rollers 10, 11 engaging the filler wire 2 is retracted by a solenoid 8 controlled by a switch 7 controlled by a heart cam 5 oscillating the electrode 1 or by a further cam which may be adjustable. The switch 7 may be mounted so as to be adjustable angularly about the cam and linearly away from the axis of the cam to vary both the duration and the points of operation of the switch 7. The oscillating speed of the electrode 1 may be reduced while the filler wire feed is stopped. A resilient lost motion link may be interposed between the switch 7 and its controlling cam 5.

The esterification is arranged to give polyesters having acid numbers ranging from 30 downwards and melting-points above 80 DEG  C. and preferably above 90 DEG  C.  A polymerization inhibitor, e.g. hydroquinone, is preferably present during the condensation.  The products can be polymerized alone or with styrene or other vinyl compounds.  In examples: (1) equimolar quantities of ethylene glycol and 2,2-di-(4-hydroxypropoxyphenyl) propane were esterified with fumaric acid to give a hard friable resin with acid number 21 melting at 104 DEG  C.; (2) 4.2 mols. of 2,2-di-(4-hydroxyethoxyphenyl) propane, 1.5 mols. ethylene glycol and 5.5 mols. fumaric acid were esterified to give a hard friable resin of acid number 20, melting at 100 DEG  C.; (3) 2.34 mols. of 2,2-di-(4-hydroxypropoxyphenyl) propane, 1.2 mols. propylene glycol and 3.5 mols. fumaric acid were esterified to give a hard friable resin melting at 107 DEG  C.; (4) the product of example (1) was compounded with diallyl phthalate, ground silica filler, titanium oxide pigment, zinc stearate and tertiary butyl perbenzoate and compression moulded into discs.  The products of examples (1), (2) and (3) are all convertible to infusible materials by heat and polymerization catalysts.  Specifications 720,566, 722,264 and 722,292 are referred to.

Filed: 1929-08-01
Abstract: 330,820. Weil, J. Feb. 11, 1929, [Convention date]. C o n t e n s, facilitating access to; lids; opening arrangements.-A case for a watch or other article has the article hinged inside the case and covered by a hinged lid, and the lid and article can be raised one after another by acting on pushes. In an example, the watch j and lid c are hinged as shown, Fig. 9, and are raised by pressing- in pushes g one at each end of the case. Springs between the two pushes ensure the return of the case to its closed condition, but by allowing the winding knob of the watch to rest in a notch q, or by any other arrangement, the watch will remain in an inclined position. The watch and lid are raised by means of pins f, Fig. 4, on lateral arms of both pushes g, which engage in slotted lugs e attached to the watch and lid on each side at the back of the hinge d. The watch is retained in the case until the lid has been raised by a hook n which is pivoted to a wall in the body of the case and which is urged by a flat spring p also fixed to the wall into engagement with notch o' in the watch j. The push controlling the watch can be operated when a boss g<2> on the push controlling the lid meets the hook n and rotates it away from the notch o<1>. The raising movement could be effected by tongues pushing on central lugs attached to the watch and lid.

Abstract: 518,490. Rubber compositions. GOODRICH CO., B. F. Aug. 16, 1938, No. 24182. Convention. date, Aug. 19, 1937. [Class 70] [Also in Groups XXXIII and VIII] A composite resilient material, applicable to inflation shoes for ice removal on aircraft, and to sidewalls of tyres, comprises a layer of rubber and a protective coating of extensible non- rubber material with particles of electrically conductive substance. As shown, overshoes 10, 13 and inflatable tubes 15, are provided on the wings and tail stabilizing surfaces of an aircraft. The units have metal fairing strips 16, 17 18 which provide electrical conductivity with the protective covering. The protective covering preferably comprises a layer of polymerized 2-chlorobutadiene and finely divided graphite which may be 2 or 3 microns in size. To facilitate coating this covering may be in the form of a solvent cement or an aqueous dispersion alternatively the covering may be deposited upon e.g. holland cloth by e.g. calendering and be subsequently stripped therefrom. The covering may be applied directly to a rubber sheet which has been vulcanized. One example of the composition is given as polymerized 2-chlorobutadiene 100 parts by volume, graphite 35 parts by volume, softener 5 per cent. by weight of the polymerized 2-chlorobutadiene with the addition of vulcanizing and age resisting ingredients and a solvent or aqueous dispersion vehicle. An example of a composite material is manufactured by coating a backing sheet of e.g. tinned metal with a lubricant, e.g. soap, sulphated alcohols, soluble cellulose esters, talc, soapstone or waterglass. One or more layers of the covering material are then applied by e.g. spraying, this is followed by a layer of polymerized 2-chlorobutadiene, polymerized 2-chlorobutadiene and rubber in e.g. equal parts by weight and finally rubber in sheet form. The overshoes and tubes are then vulcanized as a unit. The polymerized 2- chlorobutadiene may be replaced by plasticized polymerised vinyl chloride, alphatic. polysulphide or plasticized chlorinated rubber. Metallic powders may replace the graphite.

[Also in Division C1] The surface of a glass substrate is etched by applying to at least a portion of the surface a frit of a thermally devitrifiable sealing glass, subjecting the frit coated substrate to heat treatment at a temperature sufficiently high for the frit to be fuzed and to wet the substrate and for the frit to be thermally devitrified, but which is below a value at which the substrate would be warped or distorted, cooling the substrate so that the sealing glass forms a glaze on its surface and then removing the glaze and reaction products formed between the substrate and the vitreous or glassy matrix of the glaze. The removal may be effectively dissolving the glaze in dilute acid, e.g. nitric acid. The sealing glass may be applied to the substrate by spraying, dipping or silk screening.
