Patent BE-760813-A (BE)
Title: Double acting forming machine
IPC: B21J9/18
Filed: 1970-12-24
Abstract: Method is for forming small cylinders e.g. bearing runners, by a double acting punch. Bar of material e.g. steel is fed into opening of mobile knife, which also holds small forming punch be lind. Downward, movement of knife is synchronised with horizontal movement of main punch and slide, such that first short stroke performs material in die. After removal of knife second longer forward movement of main punch finalises shape. Method is particularly adaptable to semi-continuous feeding of bar stock, and fast production rates.

Abstract: VIDEO TRAVELING MATTE        SYSTEM                 Abstract of the Disclosure A video traveling matte systme is disclosed in which the video signal from a foreground television camera is examined for the presence of a particular color by an arrangement employ-ing multipliers to multiply the differences between the red and blue components of the video signal and a luminance signal derived from the video signal by the signals from a sine/cosine potentiometer.  The combined signal from the outputs of the multipliers is fed to a first comparator for comparison with a reference value, and the resulting pulses are filtered by a 4-pole active Bessel filter and compared with a reference value in a second comparator to increase the width of the pulses by a selected amount.  The pulses of increased width prevent the formation of a matte outline between foreground and background images as the true and complementary values thereof are applied to alternately gate the video signals from the foreground television camera and a background television camera to a common output.  The effects of shadows in the foreground image are maintained despite substitution of the background image by utilizing the combined signal from the multipliers to modulate pulses from the second comparator prior to use of such pulses to gate the video signal from the background television camera to the common output.  The effects of shadows are further enhanced by a logarithmic amplifier which introduces a pre-determined logarithmic transfer characteristic into the modulation signal to compensate for the black stretch circuits used in most television cameras.

Abstract: PNEUMATIC FUNCTION GENERATOR ASSEMBLY     ABSTRACT OF THE DISCLOSURE    A function generator is provided which establishes an output signal according to a functional relationship determined by the performed contour of an easily precut cam member.  The function generator includes a variable gain controller section coupled to a proximity sensing motion balance servomechanism which varies the gain of the controller according to the sensed proximity of the servomechanism to the edge of the cam member without physical contact therewith.  The cam member's position is in turn determined by an input signal which may be related to the controller input signals or may be an independent signal from a remote source.  The gain and consequently the output of the controller is varied according to the functional relation-ship determined by the precut contour of the cam member.

Abstract: ABSTRACT OF THE DISCLOSURE A phase imbalance logic module for a solid state motor protection system for a three-phase motor.  Three-phase line currents are converted to corresponding voltages and rectified.  The resultant output voltage is a poorly regulated DC voltage having a ripple of approximately 4% during normal operating conditions.  In the event of a phase failure, even if not total, the corresponding ripple percent-age increases.  The phase imbalance logic network senses ripple and provides an output signal to trip a protective circuit breaker if the component of ripple becomes signifi-cantly large.

Abstract: ABSTRACT     A lubricant valve for use in a control system for an automatic transmission including a shift valve adapted to change ratio in the transmission mechanism by exhausting a first friction device of pressure and engaging a second friction device with pressure.  The lubricant valve is connected to the shift valve and to lubricant distributing ports in the device for conducting lubricating oil to the friction plates.  The lubricant valve is connected to an exhaust conduit for the first friction device whereby when pressure is exhausted through the exhaust conduit, as initiated by the shift valve when the second friction device is to be engaged, the initial high value of pressure in the exhaust conduit acts on the lubricant valve to move same to a position to connect additional pressure momentarily to the lubricant distributing ports in the second friction device whereby temporarily a large flow of fluid is provided to said clutch plates to provide increased heat dissipation for same during engagement.

Abstract: ABSTRACT OF THE DISCLOSURE                  An improved process is disclosed for pyrometal-lurgical recovery of copper from slag material containing both dissolved and/or entrained copper values. The copper-bearing slag material is melted and treated with a hydrocarbonaceous or hydrogenous reductant in a rotary furnace, such as a top-blown rotary reactor, rotating at at least about 10 rpm, to form a high-grade copper matte phase and a slag phase of reduced copper content. The rotation of the reactor is discontinued and the high-grade copper matte phase is allowed to separate from the slag phase and is then removed from the reactor. The reactor containing the remaining slag of reduced copper content is again rotated at about 10 rpm, and iron sulfide, e.g. pyrite is added to the slag in the rotating reactor to provide a low-grade matte phase which literally "washes out" most of the remaining copper contained in the slag. The low-grade matte phase is recovered, and the remaining slag phase is discarded.
