Abstract: In a method generating correlative data from various products of thermal degradation of biological specimens and comprising sequential steps for each specimen of degrading such specimen by heating such specimen so as to cause various products of thermal degradation of such specimen to be evolved, ionizing the products of thermal degradation of such specimen by a technique causing negligible fragmentation, detecting ion currents for such specimen, and recording such detected ion currents, an improvement is attained wherein each specimen is heated in an identical non-isothermal time-dependent heating sequence, wherein a three-dimensional array comprising a large and sufficient number of ion currents, which correspond to substantially all detectible ratios of mass-to-charge within a range at a large and sufficient number of successive instants during the respective heating sequences, are detected and recorded for each specimen, and representative data from the three-dimensional array thus recorded for each one o

Abstract: An iron-chromium-cobalt magnetic alloy characterized by good magnetic quality, improved hot and cold ductility and by a reduction in the minimum temperature for complete solutioning; and processing for producing said alloy. Hot ductility is improved through controlled additions of rare earth elements in conjunction with modified refining. Cold ductility is improved through a rapid cool subsequent to hot working and prior to cold working. Solutioning temperatures are lowered through controlled additions of vanadium and titanium.

Abstract: In treating certain types of steel strip, it passes through a plurality of processes including a salt bath having a driven sink roll therein. In order to by-pass the salt bath means are provided to raise and lower the sink roll and its drive while maintaining them horizontal. This permits changing from one type of strip which is subject to the salt bath to another type of strip which is not subject to the salt bath without rethreading the entire line. A guide roll at the exit end of the salt bath tank is below and out of contact with the strip which has been in the salt bath, but is raised into contact with strip which by-passes the salt bath. A baffle is provided to cover the guide roll in its lower position and uncover it in its upper position.

The system utilizes a constant-potential multiple operator unit, suitable for gas-metal arc spray transfer welding, to which control stations may be connected to provide satisfactory short-circuiting arc operation for selected operators. The control station comprises a plurality of resistors selectably connectable in specified parallel relationships through switching means and an iron core inductor to provide the required operating characteristics for short-circuit welding.

Abstract: A control circuit is provided for a microwave oven in which a crystal rectifier is responsive to variations in the level of the electromagnetic field within the oven cavity when items of different energy absorption or reflection characteristics are placed in the oven. The electric current developed by the crystal is employed to generate a ramp type electrical signal which is compared with a fixed reference voltage to control the termination of microwave power to the oven. Compensation for the nonlinear relationship between crystal current and the level of the electromagnetic field within the oven is provided. In addition, compensation for the initial temperature of the food item which is placed in the oven is provided.

Abstract: An electromagnetic oven is provided with a control system comprising a ferrite sensor located within the oven, a magnetic property detector coupled to the sensor, and control means responsive to signals from the detector. The sensor is positioned on a tray together with the items to be heated and this assembly is preferably cooled to a uniform low temperature before the tray is placed in the oven. The sensor is thus subjected to the same thermal environment as the items on the tray so that when the tray is placed in the oven the time required for the sensor to reach its Curie point and shut off the oven is dependent upon the thermal "history" of the items on the tray.

A mixture of carbon dioxide snow and vapor is introduced into a rectangular conduit which has an inlet end, an outlet end, a discharge orifice and continuously increasing cross-section from said inlet end to said discharge orifice. At least a portion of the conduit between the inlet end and the discharge orifice is curved to define a flow path for the mixture such that carbon dioxide snow tends to be concentrated for flow in a concentrated stream through said path. Means for deflecting a portion of the mixture after it passes through said discharge orifice is also provided.

Abstract: A container for drawing or ironing dies is particularly useful but is not limited to can making. It includes an outer ring having an inwardly extending flange at one end and a disc secured to its other end so as to provide a peripheral space for receiving at least three segments which are resiliently urged against a die ring. The radial length of the slot is greater than the radial length of the segments so that the die ring can be displaced from the normal axis of the die pack. Means co-axial with the normal axis of the die limit inward movement of the segments.
