Title: Improvements in foundry moulding machines for producing cored moulds
IPC: B22C11/02
Filed: 1922-08-16
Abstract: 184,802. Ericsson, E. Aug. 19, 1921, [Convention date]. Moulding-machines; core-making; clamping moulds.-Cored castings such as tube sections are produced in a machine which comprises separate mould and core forming mechanisms and is arranged to assemble the finished parts to form the complete mould ready for pouring, which may be done with the parts in position in the machine. The machine is also adapted for forming cores and assembling them in permanent chill moulds. The mould sections are carried by arms trunnioned on sleeves 3, Figs. 4 and 5, on the rear pair of four columns 2 arranged in plan at the corners of a square, and the core-box sections 6<h>, 6v are similarly mounted on the front columns. The mounting is such that the parting plane contains the axes of the trunnions 4. After the core-box parts have been rammed they are brought together by swinging the arms 8 to the position shown in Fig. 1, but with the parting plane diagonally situated. The parts are cottared up, rotated to the exact position shown in Fig. 1, the cottars are removed, and the top core part raised by the lever-lifting mechanism 10 mounted to swivel round the columns 2 with the arms 8. The box part 6v carrying the core is now swung into position between the front and rear column and a chill or mould part is applied similarly to the assembling of the core parts. After inversion, the core box part is removed leaving the core in the mould part which is then swung between the rear columns and the other mould part is applied, after which the parting plane is turned to a vertical position if the pouring is to be done in the machine. The arms 8 may be counterbalanced, the sleeves 55, Fig. 13, being T-shaped for this purpose. The mould parts are secured together by bolts with T-heads passing through slots in lugs. When the mould parts are neither chills nor hand-rammed sand moulds, they may be produced by the moulding-machines shown in Fig. 4. The moulding boxes 21 are mounted above patterns 20 passing through stripping- plates 19 and carried by platens 34 guided at 35, 36 and connected to a worm-gear operated crankshaft 37. When the tops of the stripping-plates are level with the tops of the casings 33, spring plungers 42, controlled by levers 44, 46, snap in under the stripping-plates and lock them during the first part of the descent of the patterns. The guide-rods 35 then engage the ends 48 of the levers 46 to withdraw the plungers and allow the plates to fall back over the patterns. Ramming- apparatus may also be provided for producing the cores.

Title: Improvements in or relating to door and like operating systems
IPC: E05F15/56
Filed: 1937-08-13
Abstract: 500,635. Door-operating appliances. BAKER, W. S. GRAFF-, and LONDON PASSENGER TRANSPORT BOARD. Aug. 13, 1937, No. 22269. [Class 65 (i)] A remote-controlled dooroperating system for the doors of trains &c. comprises one or more control sub-stations for controlling the operation of individual doors or groups thereof, and one or more main stations for controlling the complete operation of the doors independently of the substations, and capable of rendering the sub-stations operative or inoperative. Each door may be operated by a .differential fluid-pressure engine 12 controlled by electromagnetically operated valves 13, and the differential piston 16,17 operates the door through a rack 19 engaging a pinion 20 on a shaft 21 carrying a spring arm engaging a vertical groove in the door. The shaft also carries a stop member 24, 25, 26 to limit the stroke of the piston. The small end of the differential piston is constantly under pressure, and the door is opened by admitting pressure fluid to the large end, and is closed by connecting the large end to exhaust. The supply of fluid to the large end is controlled by a double valve 42, 43 controlling communication between chambers 38, 39 and 39, 40. The valve is actuated by either of two solenoids, one energized at a sub-station, the other at a main station, and when it is lifted, fluid passes from 37 to 38 and then through a chamber 45 to pipes 52, 54, 55 to the large ends of the pistons. The valve is held in the open position by a piston 60 raised by fluid admitted below it from the chamber 46, which is open to 45. To close the doors, another solenoid is energized, causing valve 49, 50 to lift and close connection between 45 and 46, and open 46 to 47. This allows fluid below 60 to escape to exhaust 51 through chambers 46, 47, 40, and valve 42, 43 drops, closing 38 to 39 and opening 39 to 40. Fluid thus escapes to exhaust from the motor cylinders 14 through 45, 39, 40 and 51, and the pressure on the small ends of the pistons closes the doors. To prevent opening of doors at either end of the train if they are beyond the platform, a third double valve may be arranged between the valve 49, 50 and the cylinders 14, for the purpose of cutting off the supply to the cylinders when the valve solenoid is energized by the driver or guard of the train. At certain doors, manually-operated emergency valves 74 may be supplied, operated by a key &c. for controlling the fluid supply to the cylinders 14 independently of the magnet valves.

Title: Improvements in or relating to a process of preparing insoluble polymeric quaternaryammonium hydroxides or alkoxides
IPC: C08F8/44
Filed: 1952-09-10
Abstract: Insoluble polymeric quaternary ammonium hydroxides or alkoxides are prepared by reacting a weakly basic anion-exchange resin containing polar tertiary amino groups with an alkylene oxide containing two or three carbon atoms, e.g. ethylene and propylene oxides, at a temperature 0 DEG  to 100 DEG  C., preferably 20 DEG  to 60 DEG  C., in an aqueous medium whereby quaternary ammonium hydroxides are formed, or under substantially anhydrous conditions in the presence of an alcohol containing 1 to 8 carbon atoms, whereby quaternary ammonium alkoxides are formed.  The weakly basic anion-exchange resin may be a phenol-aldehyde-secondary amine resin as described in Specifications 556,622 and 557,414, or a cross-linked copolymer of an aromatic monovinyl hydrocarbon such as styrene which is halo-methylated and then reacted with a secondary amine as described in Specification 654,706.  A copolymer of 92-99.5 per cent styrene and 0.5 to 8 per cent divinyl benzene is prepared but cross-linking may also be effected with methylene bridges introduced during chloro-methylation of a linear polymer.  In examples, a bead copolymer of styrene and divinyl benzene, chloromethylated and aminated with dimethylamine, is (1) treated with water and liquid ethylene oxide while stirring at 40-45 DEG  C.  The quaternary ammonium hydroxide may be converted to the hydrochloride by treatment with hydrochloric acid and regenerated by treatment with dilute sodium hydroxide.  The alkoxide is similarly prepared using methyl alcohol in place of water; (2) swelled in boiling water, converted to hydrochloride and treated with ethylene oxide; or (3) propylene oxide-1,2 in water at 50-60 DEG  C. and 40 DEG  C. respectively for several hours.  The chloromethylated product may also be aminated with diethylenetriamine and the product exhaustively methylated with formic acid and formaldehyde before reacting with ethylene oxide. The strongly basic products may be used as high capacity anion exchangers or catalysts (see Group IV (b)).ALSO:Triethyl 1,1,3-propanetricarboxylate is obtained by reacting diethyl malonate and ethyl acrylate at room temperature overnight, with a quaternary ammonium alkoxide or hydroxide polymeric resin catalyst. Specifications 551,414 and 556,622 are referred to.

Title: Method and apparatus for conditioning glass which is to be continuously drawn into sheets
IPC: C03B7/06
Filed: 1955-08-09
Abstract: 771,283. Glass manufacture. COMPAGNIES REUNIES DES GLACES ET VERRES SPECIAUX DU. NORD DE LA FRANCE. Aug. 9,1955 [Aug. 27, 1954], No. 22896/55 Class 56  Glass is conditioned in a channel, between the fining zone and the bath from which it is drawn into sheets, by first cooling the glass by radiation and then cooling it by convection. The abrupt cooling of the first stage reduces the temperature of the glass below that at which bubbles of gas are produced by contact with the refractory walls of the channel. The channel walls may, moreover, be lined, e.g., with platinum to avoid bubble formation. As shown, the glass flows from the fining zone 2, under the control of a valve 8, into an inclined channel leading to the bath 4. The first cooling is by a water circulator 12 extending over the width of the glass stream, provided at 16 and counterweighted so that the radiation losses may be controlled by adjusting the inclination of the cooler. The second cooling is by passing air over the surface of the stream from a perforated pipe 27 to a suction tube 29 which is of silica and is attached to the bottom of. a counterweighted sliding gate 23 so that the tube 29 presses lightly on the surface of the stream and forms a seal. The stream is enclosed at this stage in a vault 22. The floor 6 at the first cooling stage is relatively thin to encourage a relatively high heat loss and consequent cooling of the bottom of the stream. Irregularities in the surface of the stream are prevented by a weak stream of air flowing over the stream from the tube 19 to the tube 20. The floor 6 at the second, cooling stage is thick to-minimize heat losses at the bottom of the stream. The glass entering the bath 4 is cooled at the surface by air flowing from tube 27 to tube 35, a skin thus being formed on the glass in the bath. Conventional cooling-means, not shown, are located near the foot of the sheet 11, and the outer parts of the glass in the bath aremaintained at proper temperature by heating rings 30. The sill of the fining tank is protected by a platinum sheet 36 which overlies the junction between the wall 1 and the channel and thus prevents bubble formation at this point. Specification 724,676 is referred to.
