Title: Improvements in means for heating and ventilating buildings
IPC: F24F7/013
Filed: 1950-10-10
Abstract: 685,396. Unit apparatus. VANE, M. Oct. 8, 1951 [Oct. 10, 1950; Feb. 28, 1951], Nos. 24675/50 and 4883/51. Class 137 A heating and ventilating unit for buildings, e.g. greenhouses &c. comprises a twopart casing, or duct, mounted on a board 10 sealed in a wall or roof opening, one part 24 of the casing protruding on the outside of the building having a louvred fresh air inlet and the other part 23, on the inside of the building and having a fan 14 and heating element 13, being spaced from the outer part 24 by bolts 12 and distance pieces 25 to form a flanged annular inlet 20 for recirculated air. The louvred fresh air inlet communicates with a second annular opening 26 between the rim of a fixed circular plate 27 and the inside surface of the casing 24. A solenoid 28, fixed to a plate 33 carried by the fan motor 16, when energized, moves a valve plate 38 secured to an axially moving armature 45, to close the opening 20 and open the fresh air opening 26, the reverse sequence of operation occurring when the solenoid is de-energized and the plate 38 is urged by a spring 44 in the opposite direction. The motor 16 is suspended on a metal spider 17 suspended from the casing 23, and the fan directs air over well spaced heating elements 13. The switches of the solenoid 28, the motor 16, and the heating elements 13, are controlled by heat responsive means e.g. bi-metal strips, so that the temperature within the building can be maintained within the desired range. While the building temperature remains within this range the unit is inactive; when the range is exceeded the solenoid 28 and the motor 16 are energized and cool fresh air is delivered to the room; and when the temperature falls below the range it is raised by the switching on of the motor and the heater so that warm air is recirculated. The heat elements may be protected by thermal relays which switch off the heat elements should a fault develop in the fan motor. A delay switch may be incorporated to maintain the fan rotating for a time at the end of a heating cycle to extract residual heat from the elements 13. In a modification, Fig. 4, the casing comprises a single duct of square section, the fresh air, and recirculated air openings 49, 48 being opened and closed by.pivoted vanes 51, 50 respectively in anti-phase by a solenoid 55 and links 52, 53, 54, 56. Either of the two types of units may be used in conjunction with ventilator openings situated in other parts of the building, the ventilators being operated by a shaft linked to the main, or to an auxiliary solenoid.

Title: New resinous condensation products
IPC: C08L61/34
Filed: 1944-12-18
Abstract: Resinous condensation products are prepared by heating together in acidic, neutral or alkaline conditions an etherified melamine-formaldehyde condensation product and a phenol-formaldehyde condensation product obtained by condensation in the presence of an alkaline condensation agent of a phenol, in which two of the positions o-, o- and pto the phenolic group are unsubstituted, with formaldehyde.  Specified reactants are methylolmelamines, e.g. hexamethylolmelamine, etherified by monohydric alcohols, e.g. methanol, ethanol, propanol, n-butanol, amyl alcohol, benzyl alcohol, cyclohexanol and b -ethoxyethanol; and condensation products of o-cresol, p-cresol, p-ethylphenol, p-tert-butylphenol, p-cyclohexylphenol and p-phenylphenol, e.g. p-tert-butylphenol dialcohol. Condensation agents specified are oxalic, phthalic, phosphoric and sulphuric acids, hydrogen halides, caustic soda and ammonium carbonate.  The reaction may be carried out in an inert solvent, e.g. a hydrocarbon such as toluene or xylene, through which a stream of gas, e.g. carbon dioxide or nitrogen, may be passed. The quantity of etherified melamineformaldehyde condensation product is from 60 per cent to 70 per cent to 150 per cent by weight of the phenol-formaldehyde condensation product.  The products are soluble in drying oils, e.g. tung or linseed oil, to yield varnishes. Plasticisers, e.g. castor oil-modified alkyd resins, and solvents, e.g. xylene, may be added to give stoving lacquers.  Examples illustrate the reaction of hexamethoxy-, hexaethoxy-, hexabutoxy-methyl melamine and a methylated melamine-formaldehyde condensate with o- or p-cresol-, p-ethylphenol-, p - tert - butylphenol-, p - octyl - phenol-, p - phenylphenol - formaldehyde condensation products and with cyclohexyl-phenol dialcohol to give resins soluble on heating with tung and/or linseed oil.

[Also in Division F2] An hydraulic brake in a conveyer roller comprises two, flat, coplanar pistons 43, 46 which are reciprocated in their planes, at rightangles to each other in respective working chambers C, D containing hydraulic fluid. An eccentric pin 49 fast on a stationary shaft 27 engages the piston 46 and reciprocation of both the pistons is caused when a rotor, consisting of a cylindrical cup-like body 28 and a plug-like body 29 fitted in the body 28, is driven by a load passing along the conveyer. To permit the passage of fluid within the working chamber C when the piston 43 is reciprocated, slight clearance between one or both of the flat side surfaces of the piston and one or both respectively of the adjacent radial faces of the bodies 28, 29 is necessary. Similarly, clearance is provided to permit the passage of fluid within the chamber D. Instead of relying on such clearances, communication for the fluid may comprise ducts and spring-loaded valves at A, B. Due to the strokes of the pistons being 90 degrees out of phase, a substantially uniform torque resistance to rotation of the roller is produced.
