Title: Process for the production of polymers or copolymers of acroleins
IPC: C08G2/00
Filed: 1960-06-01
Abstract: Acrolein and methacrolein are polymerized, alone or together with at least one vinylidene compound, in the presence of a catalyst promoting the polymerization of the aldehyde and/or vinylidene compound and a solvent or dispersing medium, the reaction being conducted in the presence of 0,05 to substantially 1 mol. of hydrogen peroxide per mol. of unsaturated aldehyde, whereby polymers containing carboxyl groups are obtained.  Polymerization catalyst specified are basically reacting substances, e.g. sodium and potassium hydroxides, ammonia, piperidine and triethylamine, redox systems, e.g. a catalytic amount of hydrogen peroxide or a persulphate together with ferrous sulphate, nitrous acid, potassium ferrocyanide, stannous chloride, manganous sulphate, lead acetate, sodium sulphite, sodium dithionite, rongalite, mercury chloride, silver nitrate and sulphur dioxide, benzoyl peroxide and azoisobutyric nitrile.  The preferred polymerization medium is water, but an organic solvent may be employed, e.g. benzine, benzene, toluene, xylene, chlorinated hydrocarbons, methyl, ethyl and butyl acetate, dioxane and ethers.  Vinylidene monomers specified are styrene, methyl methacrylate, ethyl acrylate and acrylonitrile.  The resulting polymers contain carboxylic acid groups, except when polymerization is conducted in the presence of an alcohol, e.g. butanol and/or pentaerythritol, which causes complete or partial esterification of the carboxyl groups.  Depending upon their content of carboxyl groups, the polymers may be soluble in water and/or soluble in alkalies.  The carboxyl groups of the polymers may also be reacted with acrolein.  In Examples (17) and (19) ethyl acrylate and methyl methacrylate are polymerized in the presence of aqueous solutions of polymers derived from acrolein, to produce a modified polymer in the form of an emulsion.

Abstract: 881,434. Steam irons. GENERAL ELECTRIC CO. June 18, 1958 [June 19, 1957], No. 19491/58. Class 138 (2). In a steam iron having a normally closed water reservoir 31 and a valve 9, 34 controlling the water flow to a steam generating chamber 7, the steam is conducted through a passage having a pressure regulating valve and leading into the reservoir 31 connected to a spray nozzle 50 with water and steam supply conduits 54 and 58 and manually operable external means for covering or uncovering the discharge opening of the spray nozzle, which may be an end cap 61 slidable thereon (Figs. 1 and 6). The water tube 54, with an inlet screen 55 extends from the reservoir's lower portion to the nozzle 50. The reservoir 31 with a fill opening 42 has a water fill valve comprising a stem 34 with a disc 47 bearing on a seat 46 biased to the closed position by steam pressure in the reservoir and by a spring 41, and to the open position by a weaker spring 48, the stem 34 on pressing the button 38 relieving the pressure of the spring 41. The stem 34 has a projection 49 which extends over the stem 24 of the pressure regulat. ing valve 23, 24, 26 capable of opening it. The steam from the water control valve is adapted consecutively to close the fill valve, to open the pressure regulating valve and to relieve the pressure of the spring 41 against the fill valve. A baffle 33 is arranged in the reservoir 31 surrounding at least the steam tube 52 which leads to the tube 58. Steam passage is deflected by a member 17 to prevent steam flowing directly to the nozzle 50. The pressure regulating valve also acts as a steam discharge valve (Fig. 3), through ports 22, a valve bushing 25, slidably mounted on the valve stem 24, carrying a sealing disc 26 which is biased by a spring 25a against the valve seat 23, a second sealing disc 24a carried by the stem 24 being biased by a spring 25 into sealing engagement with the bushing 25. The nozzle 50 comprises a steam tube 58 with an orifice 64 aligned with a passage 65 through a water tube 54, the cap 61 being outwardly movable for spray discharge through an opening 51 by means of a yoke member 67, lever 69, shank 71 and push-button 72.

Filed: 1972-04-27
Abstract: 1388205 Feeding sheets CAP CORP 27 April 1972 [27 April 1971] 19615/72 Heading B8R [Also in Division G2] In a diazo copier for making multiple copies by recirculation of an original, the original is passed over a stationary drum, having vertical end flanges which act as an edge guide for the original, by a plurality of belts which are inclined at an angle to the end flanges, so that the original is urged towards one end flange and so aligned prior to copying. As shown, the drum 14 has a series of slots 28 by means of which the original 32 is held in contact with the drum surface 16 the interior of the drum being maintained below atmospheric pressure. The separate belts 22 run over the drum surface, then under an inclined rear roller G, over a drive roller E, under two sets of conical rollers 38 and 26, over another roller A and so back to the drum. The conical rollers are shown more clearly in Figs. 2a and 2c. The drum has at one end a flange 18, and since the belts are inclined at an angle to this flange the original 32 is carried against the flange which thus acts to align the original correctly as it passes downwards off the drum into a guide 34 and along a way 36 to the printer section 42. In traversing way 36 it trips a switch SW2 which senses the number of copies required, and also a switch SW1 which initiates the movement of a copy sheet by drive 44. The original returns continually to the drum 14 until the required number of copies is completed when an ejector flap 46 is raised, and the original is then guided through exit rollers 40. The sets of conical rollers 26 and 38 are so inclined as to introduce a twist in the belts so as to realign them as they pass from rollers 38 to rollers 26.

Patent GB-199892-A (GB)
Abstract: 199,892. Kelly, J. F. May 10, 1922. Valves for cutting out elements; priming, indicating.-An emergency control valve cuts off the supply of steam to the engine when the pressure in the supply pipe falls consequent upon, say, a fracture of the pipe, and prevents the return of steam from the supply pipe when the boiler pressure falls. The valve also cuts off the steam supply when water, carried over by the steam, collects in the valve chamber. A signal is automatically operated when the valve is closed. A valve 12 normally maintained open by the flow of steam passing from the boiler connection 5 to the supply pipe 8 is closed, when the pressure in the supply pipe falls, by the pressure of steam admitted through a pipe 37 to the top of a piston 15 on the valve spindle. The admission of steam to the pipe 37 is controlled by a valve 35 which is normally kept closed by the pressure of supply steam admitted above the top of the valve through a pipe 41. When the pressure of supply steam falls, the valve 35 is opened by the upward pressure of boiler steam. The valve 35 may also be opened by a spindle 39 connected to a float in a chamber 3 in which water carried over from the boiler collects. The water is discharged through a valve 45 connected to the float. A small hole in the piston 15 allows steam to pass from above the piston to a whistle 47, and allows air to escape from above the piston when the valve 12 opens.
