Title: Controlling flying shear machine
Inventor: RICHARDS JOHN OWEN
IPC: B23D25/04
Filed: 1969-11-11
Abstract: 1286135 Controlling flying shears PRODUCTION MACHINERY CORP 11 Nov 1969 [30 Dec 1968] 55186/69 Heading B3W A first crop end is cut from a coil of strip material using a flying shear by pre-setting the shear to stop at a predetermined point in its cycle between cutting strokes, feeding the strip material to the shear at a set feed rate, detecting the advancing end of the strip material at a set point ahead of the shear and thereupon starting and accelerating the shear to a set speed corresponding to the set feed rate and then making the crop end cut, the point in the cycle at which the shear is pre-set to stop being a function of the deceleration rate of the shear from said set speed, of the acceleration rate of the shear from said set speed, of the feed rate of the strip material and of the set distance. The set speed of the shear and the set feed speed may be thread speeds, which are less than normal running speed. Leveller rolls 14, feed rolls 16, 18 and the shear 12 are driven by a common motor 30, Fig. 3. The shear cycle includes a predetermined number of misscut strokes. A photo-cell 22 detects the advancing end of the strip. In use, an input switching circuit 42 is activated by a shear pre-set button 66 and a signal from the photo-cell 22 to start the shear and accelerate it to thread speed. A shear limit switch 52 records a cutting stroke and initiates a count by a digital computer 48 of pulses from a generator 50. After a selected number of pulses, a signal from the computer causes the switching current to stop the shear. A ramp function generator 40 causes the shear to decelerate at a controlled rate to pre-set the shear accurately at the predetermined point in its cycle. The number of pulses selected depends on the distance between the photo-cell 22 and the shear, the rate at which the shear decelerates from, and re-accelerates to, thread speed and the speed of punch rolls 20 driven by a separate motor 54 which feed the strip at thread speed. Passage of the leading end of the strip at thread speed past the photo-cell 22 signals the circuit 42 to re-start the shear and accelerate it to thread speed. The punch rolls 20 are maintained at a corresponding speed by potentiometers 62 and 46 and a minimum front crop end is cut from the strip. The circuit 42 is then triggered to respond to an input from a running speed potentiometer 44 and the motor 30 is accelerated to normal running speed to shear the strip into lengths.

Abstract: 1361357 Semi-conductor devices NORTH AMERICAN ROCKWELL CORP 11 Dec 1972 [5 April 1972] 57037/72 Heading H1K A semi-conductor substrate 1 of, e.g. N-type Si with planar orientation (111) is thermally oxidized to a surface dielectric layer 2 of SiO 2  which is masked and etched in, e.g. HF to expose surface areas for selective deposition of B. Excess of the latter is removed and the remainder is thermally in-diffused to form pregions 3, 4 during which the oxide layer 2 is regrown. A second dielectric layer 5 of SiO 2  is superimposed by depositing Si from silane, and a third layer 6 of SiO 2  with P impurity is vapour deposited, which is fast etching and passivates the surface by absorption of contaminants (Fig. 1d). The structure is thermally compacted, masked by photoresist and etched in, e.g. HF to expose electrode contact regions of the substrate, and differential etchability of the tripartite dielectric causes the etched surfaces to present a slope less than 90 degrees to the substrate surface to assist in adherence of subsequently deposited electrode material. After further etching of the substrate surface an oxide layer is regrown thermally on the exposed surfaces and a thin layer of P is deposited to remove contaminants. The device is then masked and etched to expose the substrate at 1 and leave a gate oxide layer at 9 (Fig. 1g) after which a layer of, e.g. Al is deposited over the surface, masked and etched to leave gate and source electrodes 13, 14 of a FET and covered with a protective SiO 2  layer 16 (Fig. li). This is masked and etched to expose the contacts for external connections and the device is sintered at high temperature.

The leftward movement of control piston 15 causes closure of a bore 20 leading to a bore 39 connected with the return reservoir 40 before passage 22 and groove 21a are aligned, pressure fluid passing to chamber 45 via an axial bore 15. Movement of control piston 15 is transmitted to master piston 13 via spring 18. If the second circuit pressure fails piston 15 compresses spring 18 and then an end wall 25 abuts the end wall of a chamber 42 of piston 13 to establish a direct mechanical connection between the pistons. If the first circuit 29 fails, an abutment 26 of piston 13 abuts the end wall of the master cylinder and by the provision of a long slot 50 brake circuit 30 is supplied with accumulator pressure as described above. An arrangement is described which provides for actuation of the second circuit 30 in the event of failure of the accumulator and first circuit 29 in which a further master piston 48, Fig. 2 (not shown), is located between the end of the master cylinder and master piston B for pressurizing the second circuit the accumulator serving only to provide a boost pressure. In this contruction valve tappet 11, actuating ball valve 14 is fluted to provide passage of fluid therethrough.
