Title: Edm method and apparatus for finishing rolls
IPC: B21B27/00
Filed: 1969-12-05
Abstract: 1293576 Making rolls; grinding; rolling; electro-erosion INGERSOLL MILLING MACHINE CO 5 Dec 1969 [5 Dec 1968] 59546/69 Headings B3A B3D B3M and B3V A roll for rolling sheet is given a matte surface by an electro-erosion method. In one embodiment, Fig. 7, two rolls 52, which may be crowned, are mounted for rotation between headstocks 53 and tailstocks 54. One roll 52 may be rough ground by a rotary, grinding wheel mounted on a carriage 55 movable along a guide 56 whilst the other roll 52 is electro eroded by an electrode 58 positioned beneath the roll to remove the crests between the depressions produced by the grinding operation. After electro-eroding, the roll may be polished by a fine grinding operation. In another embodiment (Fig. 6, not shown), the machine is adapted to accommodate only one roll. In a further embodiment, the roll 60, Fig. 9, is electro-eroded by an electrode comprising segments 63 fixed to a beam 64 vertically movable by an hydraulic cylinder 67. Each segment 63 is connected to a separate pulser 80 and has beveled ends (Fig. 10, not shown) so as to overlie but be insulated from its adjacent segments. Two rows of segmented electrodes may be used (Fig. 11, not shown). A liquid dielectric is enclosed in a trough 74a. If the electrode is of graphite, it is initially conformed to the desired roll contour by forcing it into contact with the rotating roll 60 so that the maximum radius areas between the depressions of the roll determine the electrode contour. When a copper electrode is used it is initially worn in by electroerosion between the electrode and roll 60 with the polarity being reversed for the wearing-in process.

Title: Improvements in or relating to type-printing devices
IPC: B41J7/36
Filed: 1969-12-19
Abstract: 1,262,727. Electric selective signalling. SIEMENS A.G. 19 Dec., 1969 [20 Dec., 1968], No. 61913/69. Heading G4H. [Also in Division B6] A printer printing one character at a time from type spaced around the circumference of a wheel has, on a shaft geared to the shaft carrying the type wheel, impulse wheels which generate character timing pulses and a synchronizing pulse marking the beginning of the cycle of characters on the type wheel. Two impulse wheels generate the character timing pulses and are mechanically involved in operating the print hammer. In Fig. 1 a wheel 5 bearing type on its circumference rotates on a shaft to which is geared a second shaft carrying two impulse wheels 7, 8 and a further triangular impulse wheel 18 which are sensed by inductive sensors 15, 16 as shown, or alternatively by photoelectric sensors. The two impulse wheels 7, 8 have teeth which are staggered by half a twopitch between the two wheels and combine to produce a timing pulse as each character passes over the print hammer 13. The phase of these timing pulses can be adjusted by movement of the sensor 15 on pivoted arm 20, sensor 16 being adjusted simultaneously. The print hammer 13 is operated by either relay 9 or 10 injecting a rod 11 or 12 into the path of an impulse wheel tooth which deflects the rod downwards and operates the print hammer. Two impulse wheels and rods are provided because the time to operate one rod is greater than the time for wheel 5 to move one character position. The impulse wheels rotate at 2/3 the-rate of the type wheel 5 and to mark the beginning of the cycle of type characters in the timing pulse chain a triangular wheel 18 generates by sensor 16 synchronizing pulses, every other one of which is blanked off by means of sensor 17 and wheel 19.

Title: A method of brazing rapidly- oxidizing metals
IPC: B23K1/19
Filed: 1979-03-14
Abstract: A brazing method enabling a rapidly-oxidizing first metal (such as titanium, chromium or zirconium, or an alloy thereof) to be brazed using a second metal (such as aluminium, or an alloy thereof) at normal brazing temperatures and without the need of a flux, provides for the first metal to have its oxide layer removed, (for example by pickling followed by ion etching) and for a layer of oxide-preventing metal (e.g. copper, magnesium, zinc, germanium, silver or silicon, to be deposited thereon. In the brazing operation, the oxidation-preventing metal layer diffuses into the second metal to provide a strong ductive joint between the first and second metals. The brazing is preferably effected at about the eutectic temperature of the second and oxidation- preventing metals. The method can be applied to the brazing of two rapidly-oxidizing metals.
