Title: Method and Apparatus for Bonding Surfaces of Thermoplastic Resins.
Inventor: BAHLSEN WERNER
IPC: B29C65/74
Filed: 1966-07-12
Abstract: 1,161,901. Seaming non-metallic sheet materials; laminates. W. BAHLSEN. 12 July, 1966 [3 Sept., 1965], No. 31324/66. Headings B5K and B5N. Two webs 301, 302 at least one of which has a surface of thermoplastic resinous material, are bonded together by exposing the webs to the action of stationary means for generating an alternating magnetic field to heat by induction a metal layer of which the whole area is in contact with the thermoplastic surface and subsequently applying pressure to the webs. The webs 301, 302 may be of metal foil and paper, respectively, and at least one is coated with a thermoplastic synthetic resin on the surface which faces the other web. Instead of metal foil, e.g. aluminium or iron foil, a metal screen, wire mesh or gauze may be placed in contact with the surfaces to be bonded or previously applied to one of these surfaces. In one embodiment, Fig. 2, the webs 301, 302 pass between rollers 303, 304 and through the slot-shaped opening of a coil 305 connected to a medium or low-frequency generator. The alternating magnetic field produced by the coil 305 induces eddy currents in the metal foil web 301 so that the foil is heated to soften the thermoplastic coating. Pressure rollers 307, 308 bond the webs together. The distance between the coil 305 and the rollers 307, 308 is adjustable. In another embodiment, Fig. 4, magnets 310, 311, 312 having windings 313, 314, 315 are arranged above the webs 301, 302. Each magnet has associated therewith, below the webs, an iron element, such as 316, which may be provided with a winding 317. The magnets may be staggered, as shown, or the magnet 312 may be positioned at the location 318 or a single magnet extending across the whole width of the web may be provided. If the magnets are staggered, the pressure rollers 319, 320 may be staggered in the same manner. In a modification, Fig. 6 (not shown), the arms of adjacent magnets are arranged in a line while a body portion of each magnet is made narrow to provide recesses to accommodate the windings out of contact with each other. In a further embodiment, Fig. 7, a single magnet 327 having windings 328 has arms which converge at their lower ends 329, 330 to form a gap in which a very dense magnetic field is formed upon supply of energy to the windings 328, Fig. 8 (not shown). Pressure is applied by rollers 332, 333. The roller 332 is arranged below the arm 329 and may be secured to the mount of the magnet 327 so that the magnet and roller may be removed or swung aside as a unit when the webs are threaded through the apparatus. This removable unit may also include the roller 333.

In a modification, as applied to a machine for printing by the photogravure process, the shaft 17 is operated by a cam on the return of the bed so that the bed is out of the way of the scraper. The ink-transfer &c. roller 21 is normally operated by a pivoted cam 27 which is kept in its operative position by a roller 28. connected by a link to the bed trip mechanism, the actuation of which, as described above, moves the cam 27 out of its operative position.
Patent GB-315000-A (GB)
Abstract: 315,000. Gordon & Co., Ltd., J., (Assignees of Peebles. T. A.). July 7, 1928, [Convention date]. Air and fuel supply and draught, regulating.- In a furnace the draught is controlled by the steam condition, the air supply according to the furnace pressure and the fuel supply according to the condition of the air supply, e.g. its pressure at its entry into the furnace. As shown applied to a boiler 5 fired by pulverized fuel the steam pressure in a header 6 acts through a pressure line 13 on a regulator 12 operating a pressure relay mechanism 14 connected by a pipe 15 with a pressure-sensitive member 16 operating a damper 19 in the outlet flue 10 of the induced draught fan 9, which draws the products of combustion through a heat exchanger 11. Air is supplied to the furnace through the heat exchanger and a duct 7 by a fan 8 in the outlet of which is a damper 31 regulated by a pressure-sensitive member 26 connected by a pipe 25 with a regulator 20, 24 of the inverted bell type acted on through a pipe 21 by the pressure within the furnace which will vary according to the induced draught and the condition of the boiler. The pulverized fuel feeder 40 and pulverizer 41 are controlled by rheostats 39, 45 operated by pressure-sensitive members 38, 42, each connected by a pipe 37 with pressure-relay mechanism 36 of an inverted bell regulator 32 connected by a pipe 33 with the air inlet duct 7. A counterweight 46 on the bellcarrying lever 35 balances the air pressure on the bells. The coal feed regulator 38 acts on the rheostat 39 through a cam lever 47 so that the feed varies directly as the air flow. Fig. 2 shows the pressure-relay devices 14, 24, 36 each connected to its regulator 12, 20 or 32 by a link 50 connected with one end of an operating lever 52 pivoted on a plunger 53 extending into a chamber 54 and bearing on the top of metal bellows 55 pressed downwards by a spring 56 interposed between the bellows and a collar 57 fixed to the plunger casing. The interior of the bellows communicates with the pressure pipe 15 and the other end of the operating lever 52 is connected with a valve 59 controlling the flow of fluid pressure from a pipe 61 to the bellows and the pipe 15 and escape of air from the bellows and pipe 15 to the atmosphere through a pipe 63. On increase of pressure in the pipe 15 due to downward movement of the valve 59 the bellows 55 expands, raising the operating lever 52 and valve 59 so as to cut off the fluid pressure from the supply 61, thus returning the system to a balanced condition. The pressuresensitive members 16, 26, 39, 42 also include similar bellows mechanism 65, 66 operating a known regulating apparatus 67. Specification 214,705 is referred to.

Title: Neutral aliphatic phosphites
IPC: C07F9/142
Filed: 1953-11-13
Abstract: Tertiary aliphatic esters of phosphorous acid are obtained by mixing a phosphorus trihalide and an aliphatic alcohol at below about - 20 DEG  C., preferably at between - 25 DEG  and - 30 DEG  C., and after the reaction between them is complete, neutralizing the reaction mixture with ammonia or an organic nitrogenous base containing at least one hydrogen atom attached to the N atom at a temperature below - 20 DEG  C.  Specified aliphatic alcohols are methanol, ethanol, normal- and iso-propanol, butanols and pentanols and the phosphorus trihalide may be the trichloride, tribromide, or tri-iodide.  In an example phosphorus trichloride is added gradually while stirring at - 25 DEG  C. to anhydrous ethanol and when the reaction is complete the mixture is neutralized at the same temperature by introducing gaseous ammonia.  The ester is isolated by treating the neutralized mixture with water whilst ensuring that the pH of the aqueous phase does not fall below 5. The aqueous phase is then separated from the ester (triethyl phosphite) which can be purified by distillation under reduced pressure.

Abstract: 1305889 Lasers UNION CARBIDE CORP 6 July 1971 [10 Aug 1970] 31691/71 Heading H1C A gas laser is Q-switched by a reflector rotated about an axis which forms an acute angle with the resonator axis. The acute angle allows an adequate dwell time at high pulse rates, i.e. it allows the resonator reflectors to be in substantial alignment long enough for the active medium to saturate even though the pulse rate is high. Fig. 2 shows a CO 2  laser Q-switched by mirror 13, the mirror axis making an angle # with the resonator axis, this angle being, say, 6 degrees. A multi-faceted prism may be used as a reflector, Fig. 4, and can be placed in the active medium of the CO 2  laser to reduce drag and turbulence. The use of a 6 degrees angle allows a tenfold increase in switching rate over a 90 degrees angle for a given dwell time, the switching rate being inversely proportional to sine #.
