Patent EP-0607137-A1 (EP)
Inventor: GEIGER GORDON H
IPC: C21B13/14
Filed: 1991-10-09
Abstract: A process for the continuous production of an iron-carbon alloy utilizing an enclosed reactor (10) capable of limiting the ingress and egress of atmospheric gases and gas reaction products respectively. A solid mineral material (20) containing iron carbide and at least trace amounts of iron oxide, and having a weight ratio of at least about 2:1 or greater, is fed into a molten bath (12) of metallic material in the reactor (10). The molten metallic material is simultaneously reacted with oxygen at a temperature sufficient to generate carbon monoxide as a reaction product. The oxygen is preferably injected into the molten metallic material to facilitate the reaction of the oxygen with carbon from the iron carbide to form the carbon monoxide. The carbon monoxide subsequently enters a vapor space (17) of the reactor (10) above the molten bath (12), and further reacts with oxygen to generate carbon dioxide and heat. Products of the described method are also disclosed including a continuous supply of molten iron-carbon alloy. The system or equipment utilized in the present process is also disclosed.

Abstract: The device contains cleaning heads (4, 5) which are arranged on a shaft (1) with the possibility of free rotation. The heads (4, 5) rotate in opposite directions when the device is retracted and extended on a tension member (10) in an upcurrent. The cutting elements - blades (6) - which have an involute profile and lie on spirals directed in opposite directions, cut off the deposits. During lowering, cutting collars (14) of the blades (6), which are attached in the bottom part of the bottom head (5), perform "rough" cutting, the blades (6) of the two heads (4, 5) comminute the cut-off pieces and chips, while the cutting collars (13) in the top part of the top head (4) perform a "finishing operation" on the inner surface of the rising pipes. Mathematical relationships are cited which identify the ratio of the parameters of the components of the device: the height of the heads (4, 5) and the setting angle of the blades (6), the lengths of the shaft (1) and the stabiliser (8), their masses, the step width of the blades (6) and of the diameter of the heads (4, 5).   <IMAGE>

IPC: H04N5/10
Filed: 1992-09-25
Abstract: A system eliminates the adverse effects of serration and equalization pulses (periodically generated during the vertical sync interval) in regulating the frequency of horizontal sync pulses. These sync pulses provide timing information to regulate a video display. The system includes circuitry for stripping and processing the horizontal and vertical sync signals and the serration pulses from the video signals. These pulses are introduced to a first AND gate and through a first delay line to an input of a second AND gate. Frequency divider output signals are introduced to the first AND gate and to a third AND gate through a second delay line having an equal delay with the first delay line. The output from the first AND gate passes to second inputs of the second and third AND gates. The second and third AND gates produce signals which represent the time difference between the sync and divider output signals and which have a maximum time difference equal to the delays of the delay lines. In doing so, the gates eliminate the effects of the serration and equalization pulses. A phase comparator compares the times of occurrence of the second and third AND gate signals and introduces to a low pass filter the signals representing the time difference. A voltage controlled oscillator produces a signal having a frequency dependent upon the magnitude of the output voltage from the filter. The frequency of the oscillator signals is passed to a frequency divider. The resultant divider signals are introduced to the first AND gate and the second delay line.

Abstract: The present invention is directed toward a multicavity mold which provides a more balanced fill profile by equalizing the viscosity of the material which enters each cavity. The result is a reduced number of rejects caused by the molding process, and a finished product which can withstand relatively high temperature, is rugged in nature, and is compatible with modern high-speed pick and place technologies. 
     The development of molding compounds which exhibit low thermal coefficients of expansion and high fracture toughness has enabled transfer molding to be used in high volume production to package silicon integrated circuits. In this invention substantially identical conditions are established in each individual mold cavity of a plurality of mold cavities which are filled simultaneously during the molding process by providing runners which equalize the viscosity of the material flowing into each cavity.
