Title: Improvements in or relating to the production of resinous condensation products
IPC: C08G8/28
Filed: 1952-05-12
Abstract: Hardenable epoxy-group-containing resinous condensation products are prepared by reacting a monophenol, with at least one free hydrogen ortho or para to the hydroxyl group, with one to three mols. of formaldehyde in alkaline solution and under mild conditions to produce phenol alcohols, the phenolic hydroxyl group of which is then etherified with at least one mol. per mol. of phenolic hydroxyl group of an epihalogen-hydrin or equivalent dihalogenhydrin in presence of at least one mol. of alkali metal hydroxide per halogen atom of the halogenhydrin.  Suitable phenols are o-cresol, p-cresol, certain xylenols and p-tert.-butylphenols.  Preferably both reactions are performed without isolation of the intermediate phenol alcohols.  The whole of the alkali necessary may be present at the outset.  The first condensation is preferably carried out below 65 DEG  C.  The products can be hardened by heat, e.g. at 200 DEG  C.  Acid hardening agents, e.g. phosphoric acid, p-toluene sulphonic acid, may be added. In the examples (1) phenol is condensed with formaldehyde in caustic soda solution at room temperature, and the condensate heated at 50-60 DEG  C. with epichlorhydrin.  The product is dissolved in butanol and washed with water, leaving a resin soluble in alcohols or ketones; (2) o-cresol is the starting material; (3) p-tert. butylphenol is used, reactions being at 50-60 DEG  C.  The product is soluble in aromatic hydrocarbons.  (4) a mixture of xylenols is employed; (5) is similar to example 1.  The product is soluble in ethylene glycol. (6) a -Dichlorhydrin is used in place of epichlorhydrin.

Title: Air distribution control
IPC: F24F11/04
Filed: 1972-03-15
Abstract: 1382644 Air distribution terminals TRANE CO 15 March 1972 [16 March 1971] 12121/72 Heading F4V The ventilation apparatus of Specification 1,363,684 is modified so that it can be used with heated or cooled air, the operation of the automatic damper being reversed in the two different cases. Specification 1,363,684 describes apparatus (Fig. 1, not shown) in which the amount of cooling air entering a ventilated zone is controlled by a thermostat through a damper in the air-duct. If the temperature sensor 52 indicates a low temperature it closes a contact connected to a motor 19 arranged to close the damper. If the temperature is too high the thermostat energizes a contact connected to the damper opening motor 20. There is also a pressure-sensitive switch 38 responding to an excessive rate of flow of air in the duct to disconnect the power from terminal 41 and the thermostat 52 and to apply it instead to terminal 42 connected to the damper closing motor 19. Excessive air-flow therefore removes the thermostat from the control and closes the damper. The modification of this invention provides a pair of change-over switches 60, 61 for the two motors controlled by a heat-sensitive bulb 68 in the air duct. By this means the apparatus may be used with heated air the connections to the motors automatically being reversed so that when the thermostat detects too low a temperature the motor 20 is operated to open the damper and increase the air-flow and vice-versa. To prevent uncontrolled hunting of the control system a modification (Fig. 3, not shown) provides a second switch on the excessive air-speed detector. The damper opening motor is operated by the thermostat through normally closed contacts on the first switch but the damper closing motor is operated either directly by the thermostat or, when excess air-speed is detected, directly through normally open contacts of the second switch.

Title: Methods of electron beam welding
IPC: B23K15/00
Filed: 1971-04-30
Abstract: 1339052 Welding by fusion COMMISSARIAT A L'ENERGIE ATOMIQUE 30 April 1971 [6 May 1970 15 July 1970] 12492/71 Heading B3R [Also in Division H1] In electron beam welding along a weld line between workpiece components, using one beam, or a plurality of beams disposed along said weld line, said beam(s) being directed perpendicularly to said weld line, the value of beam power per unit area (defined in the Specification as "specific power") of the beam or beams is varied along said weld line between the leading and trailing ends of the impact area(s) of the beam or beams. Said variation of specific power may be continuous or stepped. Decrease and increase of specific power along the impact area(s), may be accompanied by increase and decrease respectively of impact area (4a-6b, not shown) or by constant impact area (Figs. 7a, 7b, not shown). Said variation in specific power assists the flow of metal to the deepest penetration so as to reduce protruding beads, shrinkage and microcavities, and to overcome defects in workpiece metal-to-metal contact. In Figs. 8, 11, irregular ended (or different diameter) tubes are welded together by leading and trailing beams of small and large specific power which may be obtained from two guns or one bifocus gun. The beams may overlap (Fig. 9, not shown). In Figs. 12-14 (not shown), a filler metal strip is wound around the joint to cater for large gaps. The beam impact area may be transversely reciprocated during beam advance. The mean line of the impact area may be angularly displaced, e.g. to assist collapse of a joint high edge. Specific power may be varied by known electrostatic or electromagnetic means. In Figs. 16, 17, and 18, 19 variation is effected by focusing or Wehnelt components 12, 14 using respectively a single, 13, or two cathodes 15, 16.
