IPC: B41M3/02
Filed: 1918-09-05
Abstract: 130,820. Cortez, O. de M., and Menezes, E. de. Sept. 5, 1918. Embossing; forming or shaping.-A modification of the process for producing relief maps described in Specification 15,245/08 consists in print. ing the map in black or colours before the embossing operation, and embossing the map in one operation instead of contour by contour. The " complementary " curves are attached together in groups to facilitate handling, and electrotypes of the relief die and of the groups of curves may be employed. From a photographic negative of the original map showing contour lines, two zinc plates are prepared, one, the " complete " zinc, containing everything in the original, and the other, the " incomplete " zinc, with the contour lines omitted. These zinc plates are secured to zinc mounts having wide margins, in the corners of which reference holes are bored. A number of zinc plates, one for each contour, and of a thickness equal to the required difference in height of the contours on the relief map, are covered on one side with paper and printed by means of the " complete " zinc. Reference holes are bored through the contour lines of these zinc plates, and they are then cut along the contour lines, a different line for each plate, and the paper is then removed. The inner cuttings are then superposed in register and secured to a base to form a relief die. The outer cuttings, or " complementary " curves are secured together in groups. Sheets of paper to form the maps are printed bv means of the " incomplete " zinc and, after being moistened, are placed on the relief die or an electrotype obtained therefrom, and the groups of " complementary " curves or electrotypes prepared from them are arranged in place about the relief die and subjected to pressure. The maps may be finally varnished.

Abstract: 1334485 Radio navigation SPERRY RAND CORP 28 March 1972 [5 April 1971] 14489/72 Heading H4D In order to produce the ground range R, Fig. 2, of an aircraft from a radionavigation transmitter by multiplying slant range D from the transmitter with sin #, where # is the zenith angle with respect to the transmitter, the sin # magnitude is obtained from the azimuthdependent signal from the transmitter. It is known that the signal strength received from a VOR transmitter varies directly as sin # but this cannot be utilized, as explained in the specification; however the field strength equation includes an amplitude modulation (A.M.) term including sin # and proportional to the fractional amplitude modulation of the 30 Hz signal on the main carrier signal, Fig. 3 (not shown). In an embodiment the airborne receiver 4 the detected carrier level at the usual A.M. detector 24 is held constant by automatic gain control on lead 17 and the output of 30 Hz filter 30 then, after accurate rectification (Fig. 6, not shown) in rectifier 35, yields sin #. If the VOR beacon is of the Doppler type, switch arm 40 is transferred to terminal 42.

Abstract: 112,635. Marshall, C. Oct. 13, 1916. Mines, marine.-Consists in controlling an electric firing circuit by a magnetic switch carried in gimbals and operated by the proximity of a magnetic body such as a ship. A disk 26 carrying permanent magnets (not shown) is mounted so that it can rotate about a vertical axis and sets itself in a definite position in the earth's magnetic field. To keep the disk horizontal it is carried by a weighted supporting member hung on gimbal mounting in a case 11. The disk carries a Y-shaped contact member 34. A magnetic needle 32 on a pivot 31 sets itself in the field of the magnets carried by the disk 26 so that one end of the needle, which is provided with resilient contact members, lies between, but out of contact with, the arms of the member 34. The members 32, 34 are in electric connexion with the leads 47, 48 of the circuit to be controlled so that when magnetic disturbance is caused by the proximity of a ship &c., the contacts carried by the needle 32 engage one or other of the arms of the member 34, closing the circuit and firing the mine. The device is described applied to a spherical mine divided into two compartments by an horizontal partition. The lower compartment contains explosive, a sparking-plug is fitted in the partition, and the upper compartment contains the battery, an induction coil, and the necessary leads. The casing 11 is mounted in the upper part of the spherical shell. When the mines are used for defensive purposes the firing circuit contains a clock-controlled switch opened at definite times, so that passage is safe during known periods.

Title: Improvements in sheet feeding arrangements for rotary printing machines
IPC: B65H5/06
Filed: 1944-07-31
Abstract: 580,577. Copying documents; feeding sheets. BLOCK & ANDERSON, Ltd., GERLACH, H., and WRIGHT, A. J. J. July 31, 1944, No. 14617. [Classes 100 (i) and 100 (ii)] In a sheet-feeding apparatus for rotary printing-machines such as manuscript hectographic machines, the sheets are fed by feed rollers 14, 15 which are driven intermittently by a clutch and act to feed positively the sheets during the first part of their motion, the subsequent feeding of the sheets being effected solely by the action of the printing-roller 10 and impression roller 11. The roller 14 may serve as the damping roller which acts upon the sheets prior to receiving an impression. The roller 14 is driven from the printing cylinder shaft by a gear wheel 42 and a bevel-gear train which drives a freely mounted gear 37 adapted to be clutched to the shaft of the roller 14 by a sliding clutch member operated by an oscillating lever 57 operated by a cam 55 on the wheel 42. The lever 57 is mounted on a pivot which can be adjusted by a screw 64' operated by a knurled adjusting nut 63, so as to vary the feed time in relation to the cylinder 10. The sheets are fed to front stops 26 when the roller 14 is separated from the roller 15 which projects through a slot in the feed table 13, the impression roller 11 at this time being held away from cylinder 10 by means of a stud 25 engaging a notch 24 in a friction plate 23 on one of the pivoted arms 21 in which the roller 11 is mounted. Extensions of the arms act upon the spring-pressed sliding bearings in which the roller 15 is mounted. When the sheet is registered and cylinder 10 rotated, the roller 11 rises and also the roller 15, and a screw 34 acts upon an arm 31 on the shaft of the registering devices so that these devices are depressed out of position. The train which drives the roller 14 can also be arranged to drive the damping supply rollers.

Title: Automatic control of crystal growth
IPC: C30B15/28
Filed: 1974-04-03
Abstract: 1494342 Automatic control of crystal growth NATIONAL RESEARCH DEVELOPMENT CORP 25 March 1975 [3 April 1974 16 Aug 1974] 14885/74 and 36288/74 Heading G3N A crystal is grown by pulling from an electrically heated melt. The crystal weight is measured by a load cell and compared with an expected value to derive a control signal which is used to adjust the power supplied to the melt heater. The control signal is compensated for known effects dependent on the rate of change of crystal radius. As shown in Fig. 1, a semi-conductor crystal 4 is pulled from a melt 1 in a crucible 2 by a pull rod 5 suspended from a load cell 6. The rod 5 is raised and rotated by motors 7, 8. In use, the load cell output is differentiated 9 and supplied to a comparator 12 which also receives a reference voltage 13 which is constant if a crystal of uniform radius is required. The comparator output signal is fed to a phase advance network 14 which compensates for thermal lag in heating coils 3 and the melt 1, and the resulting signal controls a supply circuit 16 for the coils 3. Owing to effects of change in density and surface tension, instability of the control loop may be caused by a term proportional to the rate of change of the crystal radius. This is corrected by feeding back the signal derived from the network 14 through a phase retarding thermal lag simulating circuit 18 to a differentiator 20, the output of which is combined with the signal from differentiator 9 in an adder circuit 21 to modify the input to the comparator 12. In a modification, the signal from the load cell 6 representing the crystal weight is compared directly with the output of a potentiometer whose slider moves axially with the pull rod 5. If the potentiometer is linear, this produces a crystal of constant cross-section, Fig. 4 (not shown). In other embodiments, the feedback loop 18-21 is omitted and the signal from network 14 is passed through parallel differentiating and proportional circuit branches to an adder circuit which supplies a control signal to circuits (15, 16), Figs. 3, 4 (not shown). A suitable differentiating circuit including operational amplifiers is also described, Fig. 5 (not shown).
