Title: Improvements in rotogravure printing machines
Inventor: BERRY DONALD SELLARS
IPC: B41F31/07
Filed: 1962-12-28
Abstract: 977,683. Printing-apparatus. SUN PRINTERS Ltd. Nov. 25, 1963 [Nov. 27, 1962], No. 44817/62. Heading B6C. A rotary intaglio printing-machine comprises an intaglio cylinder 1 provided with an enclosure in the form of two similar pivoted covers 7, 8 which can be swung back to an open position, a doctor blade 6, a dummy blade 113 on the edge of the cover 8 to prevent the escape of evaporated solvent, and an ink duct 5 in which the cylinder 1 is partially immersed and which is adapted to be readily withdrawn from the interior of the machine to facilitate cleaning, or to change the ink or the cylinder 1. The duct 5 is provided with a drain plug 24, a weir device 17, Fig. 3, wheeled legs 10 at one end, and wheels 11 adapted to run on rails 25, 26 at the other end. The duct may be raised on rotation of a shaft which turns four screws 31, 32 &c. simultaneously. Ink is supplied to the duct from a portable ink tank 13 which may be replaced by another containing ink of a different colour and ink flowing across the weir 17, which maintains a constant ink level in the duct, is returned to the tank via pipe 18. With the cover pivoted outwardly the cylinder 1 may be removed through a slot 9 in the machine frame 4. The positions of the blade 6 and the dummy blade 113 may be interchanged when it is desired to reverse the direction of rotation of the cylinder 1 and the ink may be fed to an alternative inlet in the duct 5, Fig. 2 (not shown), in this event. The portions 45 and 46 of the cover 7 together with the blade 6 may be swung back by rotating a shaft 47, Fig. 7, by means of an hydraulic cylinder connected to the shaft via a pinion and a segmental rack, Fig. 10 (not shown), and the cover may be locked in its operative position against a sealing member 49 on the frame 4 by a handle 53 which actuates boits connected to a double crank 52 by rods 51. The portions 45 and 46 are relatively movable by a rack and pinion device, Fig. 11 (not shown), which moves a slider 71 in a channel in the portion 45 with respect to two blocks 73 pivotally mounted on bolts 75 fixed to the portion 46. The adjustment for different cylinders can be read off a scale 79, Fig. 6. The resilient pressure of springs on the blade 6 may be adjusted by rotating a knob 115 and the blade assembly may be pivoted about a spindle 87 and locked in either end position by a push rod 84, a crank 89 and a system of keys and slots, Figs. 13 and 14 (not shown). The blade assembly is reciprocated along its length on the spindle 87 by an hydraulic cylinder 108 having a piston rod 109, Fig. 6. A sealing member 112 is provided between the cover and the blade and presses against the underside of the blade as it reciprocates. The bedplate of the machine is formed as a tray 122, Fig. 3, to receive ink spilt from the duct 5 or the tank 13. The cylinder 1 cooperates with a rubber-covered cylinder 2 which in turn co-operates with an impression roller 3.

Filed: 1968-09-20
Abstract: 1,243,801. Magnetoresistance elements. SONY CORP. 20 Sept., 1968 [23 Sept., 1967; 29 Dec., 1967], No. 44832/68. Heading H1K. A matched pair of magnetoresistance elements is made by providing a pellet of intrinsic semi-conductor material in which spaced p-type and n-type regions have been simultaneously formed, and dividing the pellet into said matched pair of elements by cutting the pellet so that each one of said pair includes a p-type and an n-type region and so that the cut sidewall of each one of said pair forms a recombination region. In an embodiment, an intrinsic Ge wafer 2 has depressions made in it to receive p-type impurity material 3a, 3a<SP>1</SP>, e.g. In-Ga, and ntype impurity material 3b, 3b<SP>1</SP>, e.g. In-As. The wafer is heated to alloy or diffuse the impurity material and leads 5 are attached. The wafer is treated in H 2 O 2  to stabilize the surfaces. The wafer is joined to a ferrite or ceramic base plate 7 by epoxy resin 6 which also covers the wafer. The wafer is cut in two by a diamond cutter, sandblasting or etching and the groove (4) so formed filled with resin (Figs. 5 and 7, not shown). In an alternative embodiment (Figs. 9 and 10, not shown) a plurality of impurity dots are formed on a semi-conductor slice and the slice cut to give individual wafers which are treated as above. In another embodiment (Figs. 11 to 19, not shown) a germanium slice is etched through a photoresist mask to give a plurality of holes to receive the alloy impurities and a framework of grooves for subsequent separation of the slice into wafers. Alloy dots are formed, the wafers separated and then treated as above. In an alternative embodiment (Fig. 20, not shown) two grooves are formed near either end of the wafer instead of forming pairs of dots, the grooves filled respectively with ptype and n-type impurity material and the cut is made across the filled grooves. Matched pairs of magnetoresistance elements having three electrodes (Figs. 21 and 22, not shown) may be similarly made by forming two holes near one end of the wafer on the top surface thereof, two holes at the same end on the under surface and two near the other end and subsequently filling with appropriate alloy.

Abstract: 1,182,675. Axial-flow compressors. DAIMLER BENZ A. G. Oct.3, 1967, No. 44900/ 67. Addition to 897, 378. Heading F1C. [Also in Division G3] At a predetermined speed, an annular valve controlling the bleed-off of air from a gas turbine compressor comes under the control of a governor 11 and is progressively closed with increasing speed to prevent pumping. As shown, when the speed increases, the end of rod 12 is seated against bellows 15 and the pressure in chamber 16 builds up, due to fluid entering at 17<SP>11</SP>, to unseat the rod again to allow leakage through the latter to restore equilibrium (at a higher pressure) in chamber 16. This higher pressure acts via 33 or bellows 31 to position spool 29 to supply servomotor 27, movement of the servopiston 26 serving to move ports 24 in valve member 23 out of line with ports 22 in the compressor casing. Movement of piston 26 causes follow-up movement of spool sleeve 30 via bell-crank 35 and lever 36.

Title: Improvements in and relating to voltage stabilizing circuits
IPC: G05F1/52
Filed: 1966-10-14
Abstract: 1,098,210. Automatic voltage control. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct.14, 1966 [Oct. 18, 1965], No.46007/66. Heading G3R. A voltage stabilizer of the type adapted to supply a regulated voltage VS having a value determined by the setting of a selector switch 1 associated with a plurality of reference voltage sources such as V1, V2 comprises a series regulating element, e.g. a valve L3, a negative feedback circuit including further valves L1, L2 and an integrating resistance-capacity network R1, R3, C1 connected to the control electrode of the series element, and means connected to modify the charge of the capacitor C1 during the selection of a desired value of output voltage whereby the time-constant of the integrating network is considerably reduced so that the output voltage of the stabilizer can quickly change from one value to another when the selector switch 1 is operated. As shown, the said means comprises transistors T1 and T2, resistors RB1 and RB2 and a voltage source B1 inter-connected with resistor R3 and the valve L2 as indicated. In normal operation transistors T1 and T2 are biased so that both are non-conducting. When, however, switch 1 is moved, say, from position V1 to position V2 the resistor R3 passes a current produced by the charging or discharging of capacitor C1; the resulting voltage drop across R3 renders either transistor T1 or transistor T2 conducting, dependent upon the direction of the said voltage drop, to cause resistor R3 to be shortcircuited, and the capacitor C1 is either charged by the source B1 or discharged to earth, whereby there results in an acceleration of the changeover from one voltage value to another. Diodes D1 to D4 protect the base/emitter junctions of transistor T1, T2 against excessive voltages which may arise if the difference between V1 and V2 is large. The series regulating element may be a transistor, and such an embodiment is described with reference to Fig. 4 (not shown).

Abstract: 1300930 Photo-electric distance measurement KERN & CO AG 23 March 1970 [22 April 1969] 46844/69 Heading H4D  In a system for measuring distances in terms of the number of complete wavelengths and the fractional part of a wavelength of a modulating wave, e.g. a decimetric wave, the ambiguity in the number of complete wavelengths is resolved by using several auxiliary wavelengths of successively longer beat wavelength, a mechanical hybrid computing system ensuring that each successive decimal place in the measurement, above the lowest, is determined exclusively by one of the auxiliary wavelengths. As shown the fractional parts of the wavelengths, in the form of phase angles are communicated by a shaft 2 to clutches K 0 -K 3 . For the two lowest places (measuring wave # 0 ) only clutch K 0  is engaged and this communicates the movement in analogue fashion through gear train 4 to counting wheels 6, 7. For the next place (first auxilary wave # 1 ), all the clutches are engaged and clutch K 1  drives a stepping mechanism 11 operating counting wheel 17 in digital fashion. For the next place (# 2 ) only clutches K 2 , K 3  are engaged and the stepping mechanism 21 operates counting wheel 27; and so on, as shown in the table. Differential mechanisms 12, 22, 32 allow a transfer of carry digits between the counting wheels without feeding back to the stepping inputs. To ensure that only the required decimal place is transmitted by, say, mechanism 21 the fractional part from the previous measurement, suitably reduced, has been subtracted by differential 24; and so on. The gearing is selected so that the phase angles indicated by shaft 2 are displayed in terms of the required units, e.g. metric, on wheels 6, 7, 17, 27, 37, 38. A resetting mechanism is provided and this need not be reset to zero, where it is desired to add a constant to the displayed reading.
