Patent EP-0016267-A1 (EP)
Inventor: YOSHIDA KEIICHIRO
IPC: B21F9/00
Filed: 1979-03-15
Abstract: For subjecting a continuous strip of metallic-material or stock to an applied high tension for a drawing, straightening or stretching process, apparatus is disclosed which comprises a pair of elastic ring-equipped roll assemblies for holding the material there-between under a high tension applied by the roll assemblies. The elastic ring (5,6) of each roll assembly is capable of elastic deformation which elongates the area of the ring in contact with the material (13) along the circumference of the ring as applied tension increases, thus increasing the contact area over which the applied force is distributed evenly. This results in a reduction of the force per unit area. Each elastic ring is mounted on a shaft (1,2), at least one of the shafts being drivable, byway of atleastthree rollers (3,3a 3b; 4, 4a, 4b) which are interposed between the ring (5,6) and shaft (1,2) for axial rotation and two of which (3, 3a; 4, 4b) are arranged to bridge the ring overthe ring contacting area ofthe material.

Abstract: A compensation circuit for overshoot, undershoot and delay occurring in response to sudden D. C. level changes in signals received by reactive filters. A D. C. level change, represented by an input signal step applied to the reactive filter is detected by the compensation circuit. The compensation circuit responsively provides a compensation D. C. signal step of a predetermined magnitude and polarity with respect to the input signal step. The compensation step is applied by the circuit to the signal return line of the reactive filter, simultaneously with the input signal step received by the filter to maintain a substantially constant D. C. signal level with respect to the reactive filter elements. The reactive filter elements are thus prevented from charging and discharging in response to the input signal step and filter delay is eliminated.

Abstract: The method is more specifically directed to treating wet agglomerate cement material in a pyro-processing system in which the material to be treated by heated gas is carried by a grate through a drying zone, from which spent process gases are vented to atmosphere, a preheat zone, a kiln, and a cooling zone. The novelty resides in the steps of elevating the temperature of off-gas after it has passed from the preheat zone and passing the preheat off-gas at an elevated temperature directly back into the pre-heat zone. 
<??>The apparatus includes a grate (20), low and high temperature drying zones (14, 16), a preheat zone (17), a kiln (18), and a cooler (19), all well known in the prior art. Novelty is believed to reside in the preheat to preheat circuit comprising duct (22), separator (23), fan (24), and booster heater (26). Novelty is also believed to reside in additionally providing a quenching chamber (27) to receive kiln off-gas and in the use of preheater off-gas via duct (15) to quench the kiln off-gas in the quenching chamber. Off-gas from the high temperature drying chamber is also passed through duct (42) to quenching chamber (27).

Abstract: A valve, notably for use as a demand valve in breathing apparatus, has a pressure-responsive diaphragm (25) coupled to a separate control member (18) which lies in the path of a jet of gas which vents from a control chamber (14) through an orifice (17), gas being continuously supplied to the control chamber via another orifice (16). Deflection of the diaphragm in response to pressure changes in a chamber (42) caused by inhalation and exhalation pivots the control member towards or away from the orifice (17) to control the rate of venting from the control chamber and thereby vary the pressure within the control chamber. Flow of gas through the valve to the user of the apparatus is controlled by a flexible disc (10) which in turn responds to the pressure in the control chamber. By employing a separate diaphragm (25) and control member (18) the former can be optimised for pressure-response while the latter can be optimised for valve-regulation by interaction with-the gas jet from the control chamber.
