Title: Process for the manufacture of carrier webs impregnated and coated with curable synthetic resins for surface finishing purposes
IPC: D21H27/24
Filed: 1974-10-18
Abstract: In order to produce a carrier web which has been impregnated and coated with curable synthetic resins for surface coating of, for example, boards made from wood materials, a carrier web of paper is first impregnated with an aqueous solution of urea-formaldehyde precondensate, which may additionally contain melamine-formaldehyde precondensate, and is predried. In a second operation, the predried carrier web is coated with an aqueous dispersion of curable copolymer comprising a hard, brittle copolymer A and an elastomeric copolymer B, and is dried. The copolymer A comprises predominantly monomer units of styrene and/or alkyl methacrylate and contains glycidyl acrylate or methacrylate in copolymerised form. The copolymer B comprises predominantly monomer units of alkyl acrylate. Each of the copolymers A and B contains monomer units which contain a free or amidated carboxyl group or one which has been esterified to give hydroxyalkyl esters, or a carboxylic anhydride group. By means of the combination of amino resin precondensate and curable copolymer, tack-free webs with a long shelf life can be obtained which, on pressing under curing conditions, give haze-free, crack-resistant and stable surface coatings.

Abstract: 1,150,918. Seaming non-metallic sheet material. ARENCO A.B. 17 Oct., 1966 [1 Nov., 1965], No. 46308/66. Heading B5K. A collapsible tubular container 5 provided with a longitudinal welded seam 6 and having a laminated wall comprising an inner layer of plastics material having a low dielectric loss factor, a metal layer situated outside the plastics material and possibly a layer of paper and/or plastics material situated outside the metal layer, is transversely sealed by pressing two jaws 7, 8 against the container 5 in such a way that when the region to be sealed is pressed flat the seam 6 abuts the jaw 7 and then applying a high frequency current of short duration to a conductor 13 in the pressure surface of the jaw 8 so that currents are induced in the metal layers in the region of the jaws 7, 8 to heat the adjacent inner plastics material layers and form a welded seam. As shown, each tube 5 is mounted in a cylindrical insert 4 rotatably mounted in a holder 2 mounted on two chains 1. The jaws 7, 8 are slidably mounted on a rod 9 and actuated by links 10 connected to pivoted arms 11 mounted on a stationary shaft and driven by means not shown. The jaw 7 comprises an insulating material resiliently mounted against the action of springs 12. The jaw 8 is provided with a copper conductor 13 of square or rectangular cross-section and connected by blocks 15 to a high frequency current source. The chains 1 are driven stepwise so that two tubes at a time are advanced to the jaws 7, 8, Fig. 2 (not shown). A device 16 is arranged to optically sense the position of a mark 17 of the tube 5 and controls a motor 18 which, through a gear 19 and a drive wheel 20 engaging a friction surface 21 on the holder 2, rotates the holder 2, if necessary, until the device 16 detects the mark 17 to position the tube 5 with its seam 6 facing the jaw 7. This prevents excessive heating of the seam 6 during transverse sealing of the tube 5. The conductor 13 is cooled by connection to a water-conduit (22), Fig. 2 (not shown).

Title: Improvements in methods of and means for controlling braking of lifts
Inventor: RUFLI ANTON
IPC: B66B1/44
Filed: 1963-11-27
Abstract: 1,005,143. Control of A.C. Motors. INVENTIO A.G. Nov. 27, 1963, No. 46762/63. Heading H2J. A lift is driven at full speed when a low-pole motor 1 is energized, a tachometer generator 11 charging capacitors 13, 14. At a fixed distance from a floor, capacitor 14 is disconnected from the tachometer generator but retains its charge, the motor 1 being disconnected so that the lift is retarded or accelerated in accordance with the load. A transistor 19 receives a control signal representing the difference of the voltages across the two capacitors, the capacitor 13 being disconnected from the tachometer generator after a set period but still retaining its charge. The voltage developed across terminals 24.1, 24.3, of a comparator relay now represents the ioad torque of the lift. Braking operation is introduced by energizing high-pole motor 2 through induction regulator 4, a servo motor 3 rotating to increase the secondary voltage of the regulator and the braking torque. A direct voltage, which is proportional to the secondary voltage of the induction regulator, is developed between terminals 24.2, 24.3, of the relay 24. When the potential at terminal 24.2 becomes equal to that at terminal 24.1, the relay operates to disconnect the servomotor 3 so that the induction regulator is stopped in a set position. After the braking period, the lift is driven at a creep speed by the motor 2, the induction regulator being driven into a limit position in the same direction as before. The polechanging arrangement may be replaced by one involving variable frequency.

Abstract: 1395038 Valves ITT INDUSTRIES Inc 11 Oct 1972 [18 Oct 1971] 46783/72 Heading F2V A rotary ball valve has a plug 7 with an indentation 33 formed by a plurality of overlapping conical cavities 34, 35, 36 and 37 of different diameters, whereby the presentation of different portions of the indentation to the periphery of the inlet 2 varies the flow through the valve. With the valve in the "closed" position there is a clearance of approximately À032 inches between the seat 23 and the face of the plug.

Abstract: 1439391 Thermonuclear fusion apparatus BRIGHAM YOUNG UNIVERSITY 16 Oct 1973 [25 Oct 1972] 48090/73 Heading G6P A plasma for production of energy by controlled thermonuclear fusion is generated and confined in a toroidal chamber such that the poloidal cross-section of the plasma has a non- convex part adjacent the inner periphery of the torus. The plasma is stated to have static structural stability. The plasma 14 (Fig. 3A) is confined by two sets 124, 125 of magnetic field lines. The non- convex arc 4, 6, 5 of the plasma lies adjacent the magnetic surface defined by set 124; a poloidal current component along this arc is oppositely directed to the poloidal component along the convex, outer arc 4, 7, 5. Points 4 and 5 on the plasma surface thus are poloidal stagnation points lying on a closed loop toroidal current path 15, 16. Other plasma shapes having the same basic principles are described. In a preferred arrangement (Fig. 2A) for confining the plasma, an electrically conductive torus 10 defines a chamber enclosing a magnetically permeable, dielectric (e.g. quartz) envelope 12 divided by partition 120 into a pair of chambers 121, 122.

Externally of envelope 12 is another toroidal conductor 13 comprising a plurality of wires. In an alternative arrangement (Fig. 2B), the envelope 12a is of circular cross-section, without an internal partition, and the requisite conductors are all arranged externally, and circumferentially, of the envelope.

Abstract: 1,093,224. Cooling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 23, 1964 [Dec. 10, 1963], No. 48832/63. Heading G6C. In a liquid sodium-cooled nuclear reactor, the sodium is continuously monitored to detect the concentration of an impurity, soluble sodium oxide. The coolant flows through an orifice and by the automatic control of both the sodium temperature and the flow rate through the orifice the oxide precipitation at the orifice is adjusted. The automatic control is effected in correspondence with the orifice temperature and the flow rate. The impurity concentration, is indicated by the orifice temperature measured on a thermocouple. The sodium temperature at the orifice is varied in correspondence with the impurity concentration so as to regulate the amount of precipitation plugging at the orifice and hence to maintain a steady flow rate. The device is subjected to a constant degree of forced cooling which is offset by variable electrical heating. An electromagnetic flowmeter may be employed and the thermocouple may comprise two thermocouple materials shaped as an orifice.
