Title: Foamed sealing strips
Inventor: ALDERFER STERLING WILLIAM
IPC: B29C44/32
Filed: 1957-09-23
Abstract: 833,552. Moulding foamed sealing strips. STERLING ALDERFER CO. Sept. 23, 1957, No. 29866/57. Class 87(2). [Also in Group X] Sealing strips are formed by depositing a chargeof unexpanded material which will react to form a foam on a moving web of flexible material, joining the edges of the web to form a jacket and allowing the reaction to run in the jacket. As shown in Fig. 1 apparatus for the manufacture of the sealing strip includes an air tight mixing chamber 19, including a mixing screw 20 rotated at a speed depending on the mixture, to which polyester, polyether or like compounds, water and the catalyst are pumped from tank 1 and a suitable isocyanate or polyisocyanate is pumped from tank 2. The mixture is then fed through a flexible tube 25 on to the lowermost portion of a web of polyethylene film which forms the sealing strip jacket. The web is drawn. from a drum 33 by the action of the sealer 60 (see below) and is folded by passing over a triangular plate having two upstanding side flanges so that the sides of the web are drawn together. The upper parts of the web are sealed together to form a flap by a pair of endless stainless steel resistance heated belts or tapes 68, Fig. 3. The web then passes between two pillars 81 one of which is adjustable' so that the reactant mixture is compressed to exclude air. The sealed web is then fed onto a chain 92 which carries groups of pins 94 which pierce the flap and suspend the strip until the reaction is complete. The sealing pattern is such that rectangles 140 and 142, Fig. 20, of the lapping edges are sealed together thus leaving passages 141 extending transversely of the core along which the foam expands. Alternatively, Fig. 23, the lapping edges are sealed together at small rectangles 144, 145 between which the foam expands. In a second embodiment the web is a vinyl film and is coated before folding with an adhesive, or an adhesive coated vinyl tape is sealed to the lapping portions during the sealing operation which in this case would be by induction heating. The lapping edges may also be stitched together.

Title: Improvements in milling cutters
IPC: B23P15/34
Filed: 1919-12-03
Abstract: 164,047. Marks, E. C. R., (Pratt & R Whitney Co.). Dec. 3, 1919. Milling - cutters; backing-off lathes.-A backedoff milling-cutter for cutting contours, parts of which are considerably inclined to the axis of the cutter, has longitudinally-inclined teeth, the cutting edge being so formed that its projection about the axis upon an axial plane gives a curve identical with the contour to be cut. The teeth overlap and may be radially faced or undercut. The front face of each tooth is preferably a helicoid and the backing-off curve at any cross-section a spiral, so, that an effectively unaltered cutting face may be obtained by grinding each tooth to a new face parallel to the original face. Figs. 1 and 2 show a cutter B with radially-faced teeth, and Fig. 18 shows diagrammatically a machine for making such a cutter, by means of a fine-pointed tool S which travels a distance less than its width for each complete revolution of the blank D, being guided by a former W. To produce the backing- off curve the tool S is reciprocated through a distance r, Fig. 9, for each tooth on the blank, by a cam 45 driven by worm gearing 51 and bevel gearing 52 from a shaft 48 and operating a slide 40 carried on the main cross-slide 39. As the tool S travels to the left, the alteration in phase of the reciprocation, necessitated owing to the inclination of the teeth to the axis of the blank is produced by means of a cam-slot connection 60 between the driving sleeve 56 and the mandrel 55, under the control of an arm 58 attached to the carriage 38. In the case of undercut teeth, a retarding of the backing-off action is provided for by arranging the bevel-wheel 52 to slide on its shaft in unison with the main slide 39 and to be driven by the shaft 50 through longitudinal cam slots (not shown).

Abstract: 634,258. Casting composite articles; casting- machines. SOC. ANON. DES MANUFACTURES DES GLACES ET PRODUITS CHIMIQUES DE ST.-GOBAIN, CHAUNY, & CIREY. Nov. 13, 1947, No. 30247. Convention date, Nov. 14, 1945. [Class 83 (i)] A glass to metal joint is made by casting the metal in a mould formed on the glass so that the part of the glass on which the joint is to be made forms one wall of the mould, the temperature of the glass and the mould wall at the time of casting being sufficiently high to prevent any impurities being occluded in the metal at the joint, while being below the temperature at which the glass softens. The casting is carried out in a closed chamber 1 containing an inert gas. The glass sheet 2 rests on a heating plate 3 which is supported on a movable carriage 4. The glass may first be tempered by heating it to near its softening point and then suddenly cooling by an air blast, the air blast being stopped when the glass is at a suitable temperature to receive the molten metal. Moulds 4 are placed on the glass sheet and lagging 9 packed between the moulds. A crucible 10 having a narrow outlet 11 which can be closed by a valve 12 is charged with metal and heated electrically to a temperature controlled by a thermostat 16. The moulds 8 are placed under the outlet 11 one at a time, and each filled with molten metal. When the casting is completed the apparatus is allowed to cool slowly, and when cool the glass sheet is removed from the chamber and the moulds 8 and lagging 9 removed therefrom. In a modification the mould may be made of copper or plated with a suitable metal so that it may be used as a permanent sheath for the cast metal. The process may also be used for joining together glass objects, for example to make glass vats, by casting a suitable metal between the edges of the glass, for attaching metal fittings to windows, or for providing a metallic coating on the glass to form a mirror. In the lastnamed method lagging is supported a small distance above a heated glass sheet and the space between filled with the molten metal. Suitable metals for casting on to glass are lead or a zinc and tin alloy.
