Title: Rotary machine for expanding metal sheets
IPC: B21D31/04
Filed: 1925-10-26
Abstract: 249,761. Halls, J. A. Oct. 26, 1925. Making expanded metal.-A machine for expanding pre-slotted metal sheets, particularly for forming metal laths of the herring bone typeshown in Fig. 9, comprises a die member at the edge of a table top, a ribbed expanding drum rotating near the die and a carrier operating over the table top for supporting a sheet and advancing it to the drum. The feed table B has a feed bar 14 of angle iron mounted on parallel links 15, and the slit metal sheet S to be expanded is supported on the table in an angular position by a groove 23 in a plate 19 carried by the feed bar 14, which is actuated to move the edge of the metal sheet into contact with the ribbed drum F by means of a handle extension 18 of one of the links. The pressure bar D above the die block C is pivoted in the frame brackets E so that it may be tilted out of the way whilst the sheet is placed in position. Stop plates 25 prevent the pressure bar D from being forced out against the drum. The frictional resistance to the! feed of the metal sheet between the pressure bar E and die C is less than the force exerted by the teeth 2 of the drum so that longitudinal movement of the sheet relative to the drum is permitted during the expansion of the slits. The drum is rotated from a mainshaft 7 through gearing 4, 5, 6 by a one-revolution clutch 9, which is automatically disengaged by a trip lever 10 and detent x and reengaged by a hand lever 12. Specification 235,048 is referred to.

Filed: 1937-10-04
Abstract: 503,334. Motor power plant. BAUER, G. Oct. 4, 1937, No. 26813. Convention date, July 13. [Class 110 (iii)] [Also in Group XXXIII] A marine turbine plant has for cruising speeds an uncouplable high-speed high pressure reciprocating engine with or without a succeeding exhaust turbine which as regards the steam supply is connected in parallel with the high pressure turbine of the main plant and directly or indirectly drives a pinion engaging a large gear wheel on the main turbine shaft. The plant,' Fig. 1, consists of a reciprocating engine K exhausting into the low pressure turbine 4 of the main plant, and a high pressure turbine 8. For cruising.speeds, the turbine 8 is uncoupled from the pinion 9 by the coupling 10 ; for full speed travel, the reciprocating engine is disconnected by empty-. ing the coupling 2. The exhaust of the engine K may be taken to an intermediate stage of the turbine 8. The plant, Fig. 4, is an arrangement comprising two reciprocating engines. In this plant the H.P. turbine 15 drives the pinion 18 through the gear stage 16, 17 built into the hydraulic coupling 2. The I.P., cylinder 20 of the main turbine plant drives the pinion 21 through a releasable coupling. The reciprocating engine exhaust in this erise may be led to the L.P. turbine 19 or the I.P. turbine 20. Intermediate reheaters may be connected between the H.P. and L.P. cylinders of the reciprocating engine or between the L.P. cylinder and the succeeding turbine. The reciprocating and exhaust steam turbine set may be coupled only to the middle shaft of a triple shaft ship or the two inner shafts in the case of a quadruple shaft ship. Mechanical or hydraulic coupling can be used for disconnecting the various portions of the plant.

Title: A method of,and apparatus for,chipping or flaking glass
IPC: C03B23/02
Filed: 1964-06-29
Abstract: <PICT:1065732/C1/1> A decorative effect is provided on glass objects by superficially heating at least a part of a surface with a concentrated source of heat to produce internal stresses in the object, and then allowing a coolant liquid to act upon the object to effect a cracking which results in flakes which can be removed. Preferably the glass object 12 is immersed in a bath 10 of a non-inflammable liquid such as water wherein it is heated by means of an oxy-acetylene flame 16 or an electric arc.  When heating is interrupted, the liquid immediately causes thermal shock on the object 12.  The coolant liquid is continually stirred with a circulatory motion and its depth above the object 12 may be varied for different effects.  To aid the flaking, the glass object may be pre-cut and may be smeared with an oil or grease to prevent too great a shock, or may be masked with insulating material.

Abstract: 260,605. I. G. Farbenindustrie Akt.- Ges., (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). Oct. 28, 1925, [Convention date]. Addition to 241,767. Alkamine esters of N-substituted o-aminobenzoic acid are prepared by esterifying an o-N- monoalkylaminobenzoic acid, in which the alkyl group contains more than two carbon atoms, or an o-N-manoalkyloxylalkyaminobenzoic acid, with an amino-alcohol, or by treating an alkamine ester of o-aminobenzoic acid with an alkylating agent capable of introducing an alkyl group containing more than two carbon atoms, or with an alkoxyalkylating agent. The products possess anaesthetic properties. According to the example, sodium anthranilate is heated with #- chlorethylmethyl ether, the resulting N-#- methoxyethylanthranilic acid then esterified with ethyl alcohol, and the ester heated with #- piperidino-ethanol in the presence of sodium ethylate; on adding ether to a, solution of the product in alcoholic hydrochloric acid, the monohydrochloride of N-#-methoxyethylanthranilic acid-#-piperidino-etlhyl ester separates out.
