Title: A method of making press structures
IPC: B23P15/00
Filed: 1941-03-26
Abstract: 546,834. Making machinery beds and frames. MULLER, J. A. March 26, 1941, No. 4086. Convention date, Jan. 2. [Classes 38 (iii) and 83 (iii)] Boring.-A press, having a head 3, Fig. 13. and base 2 as described in Specification 546,835, is made by casting these as a single hollow unit with side windows 7, Fig. 2, and an opening 6 in the base, introducing a boring bar 9, to carry tool holders 11 ... 15 and 19, for machining the interior in a single set-up, and introducing the necessary parts of the press through said windows 7 or opening 6 or both. After machining the interior, the casting is turned through 90 degrees on the bed 16, the bar 9 is passed through the windows 7, and guiding surfaces 22 are milled at the windows. Then the casting is placed in inverted position, the ram 26 is lowered through the opening 6 into the cylinder 17, Fig. 5, and is supported by a strut 25. Packing and retaining ring segments 31 are inserted and a platen 35 is inserted through a window 7 as shown in Fig. 8 and then rotated through 90 degrees, being centred by a block 33. The ram &c. are temporarily secured by a device 23, 40, 37 and the casting uprighted as shown in Fig. 7. A base plug 48, with flats 45 like the platen, is then inserted, rotated through 90 degrees, made into a complete cylinder by bolting on segments 50, Fig. 11, and lowered into place by jacks 42. Push back cylinders 53, Fig. 13, with plungers 54, are then inserted, in collapsed condition through the windows 7 into bores 52, connected to a fluid supply, and expanded to take the weight of the platen 35 &c. so that the device 23 &c. can be removed. Supply and exhaust pipes 61, 62 and a surge valve 58 and tank 60 are then fitted to the cylinder 17. Guiding lugs are also secured to the flat faces 45 of the platen to engage the sides of the windows. In a modification the opening 6 is larger in diameter than the platen and base plug 83, Fig. 18, to permit axial insertion thereof and avoid the necessity of the flats 45. Blocks 78 are then inserted, the plug is lifted and supported by jacks resting on the platen 35 while the cylinders 53 are inserted. After uprighting and removing the strut 25 and the jacks, guideways 92, Fig. 22, are mounted to engage the pattern by screw sockets 94 and bolts 93. If the cylinder 17 has a shoulder 99 the strut 25 is not required, and in this case the device 23, 40, 37 may be replaced by a bolt passed through the hole 5 into the ram.

In another construction the teeth on the members engage recesses in two rings separated by a third member which has teeth engaging recesses in the two rings. The third member has a rubber ring located between its periphery and the inner surface of the drum.

[Also in Divisions G3 and H2] A portable electricity generating set for supplying arc welding or like intermittently operable apparatus, comprises an I.C. engine M and an A.C. generator A and the throttle valve of the carburetter 20 is controlled by speed governor, biased by a spring 44 providing an adjustable loading, to maintain the engine at a predetermined speed when generating set is subject to a load. A solenoid 50 having a core 51 is arranged to relieve the bias of the spring 44 on the governor when the generating set is not subject to a load so that the governor acts to maintain the engine at idling speed, e.g. 3000 r.p.m. The governor may be a vane 42, Fig.4, arranged in the outlet duct 23, 24 from a pair of coaxial fans 14 and 15 mounted on the engine and generator shaft 17 and drawing cooling air through a passage 26 defined in an outer casing 27 and passages 28, 29 and 30 around the shaft bearing and in generator rotor and stator. A centrifugal governor 100...104, Fig.7, may be driven by the engine crank. The generator A has a power factor correction condenser 34 and conductors 62, Fig.8, connected to either side of the condenser, lead to a switching and time delay circuit D for the solenoid 50. Power for the solenoid is provided by a flywheel magneto G, Fig.8, mounted in the space 16, Fig. 4, between the fans 14 and 15. A magneto coil 63 provides power for the spark-plug 67 and a coil 64 is connected is the solenoid circuit 73 through the circuit D and to an excitation circuit 69, 70, 71 for the generator A.

According to the example suitable substances may be prepared by (1) heating palmityl chloride in epsilon-amino-n-caproic acid at 130 DEG  C., and stirring the resulting product with n-octadecyl-amine at 150-160 DEG  C.; (2) heating palmityl chloride with p-aminophenyl acetic acid at 250 DEG C., and stirring the resulting product with n-hexadecylamine at 200 DEG  C.; (3) heating sebacic acid with tetradecylamine; (4) stirring a mixture of dilauryldiethylene-triamine with succinyl chloride at 150-160 DEG  C.; (5) adding dropwise with stirring succinyl chloride to monostearyl hydrazine heated to 150-160 DEG  C.; (6) stirring a mixture of n-octadecyl chloroacetamide with diethylenetriamine at 150-160 DEG  C.; (7) adding piperazine hexahydrate to n-octadecyl chloracetamide with stirring at 150-160 DEG  C.; (8) heating a stirred mixture of n-octadecylchloracetamide with m-phenylene-diamine at 150-160 DEG  C.; (9) adding dropwise with stirring and simultaneously ethylene dichloride and diethylenetriamine to n-octadecyl-chloracetamide heated to 150-160 DEG  C.  The above mentioned substances may be dispersed or admixed with sodium carbonate or other materials used for treating water; or they may be dissolved in organic water-mixable solvents such as alcohols, ethers and ketones or emulsified in water with the aid of non-foaming emulsifying agents, with or without the addition of sodium carbonate and in these forms added to the water.  They may be used with other known anti-foaming agents such as castor oil, or along with other materials used in water treatment such as chestnut tannin or gallic acid.  They should preferably be added to water which has been treated to remove hardness and after the removal of the precipitated hardness-forming constituents.
