Abstract: 1,220,370. Printed circuits. LITTON INDUSTRIES Inc. 29 July, 1969 [13 Aug., 1968], No. 57698/68. Addition to 1,145,771. Heading H1R. In a multilayer printed circuit board of the kind comprising metallized holes which interconnect terminal pads at different levels in the board, at least two such holes separated by at least one insulating layer extend in at least partial alignment within the board. As shown, Fig. 1d, apertures 13 are formed by a photoetching process in the Cu cladding 12 on one surface of an insulating substrate 10 having similar cladding 12<SP>1</SP> on its other surface. Holes 18 are then etched in the substrate, which may be of epoxy glass, in which case the etchant may be a mixture of HF and H 2 SO 4 . Cladding 12 is removed, and the walls of holes 18 are metallized by electroless plating followed by electroplating, e.g. with Cu, as shown at 20 in Fig. 1h. The exposed surface of substrate 10 is again Cu-coated, as by cladding under heat and pressure followed by electroplating, the Cu coating then being photo-etched to form a pattern of conductor 26 and round pads 28 above metallized holes 20; the pattern is given a coating 30 of Au. A layer of partially cured plastics material (32, Fig. 1i, not shown) is applied to the pattern-bearing surface of the substrate, and a second insulating substrate (34) clad with a single Cu lamina (36) is bonded thereon by heat and pressure. The steps for the formation of metallized holes and a conductive pattern are then repeated; and so on, for subsequent layers. When a multilayer circuit board has been produced, it is inverted so that cladding 12<SP>1</SP> is on top (Figs. 3, 3a not shown) and the cladding is etched to form terminal pads (12<SP>1</SP>a), to which are connected the leads (38) of electronic modules (37), and mounting pads (12<SP>1</SP>b) on which the modules lie, and which are in contact with heat conductive metallized holes (54), formed through the substrate, which in turn are in heat-exchange contact with earthing layers (46, 52) on the other surface of the substrate.

Abstract: 1,177,319. Cathode-ray tubes. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 19 Dec., 1968 [22 Dec., 1967], No. 60381/68. Heading H1D. In a cathode-ray tube with a deflection amplifying quadrupolar lens 5, Fig. 1, the astigmatic beam focusing effect of the quadrupolar field is compensated for by making the beam astigmatic before it enters the quadrupolar lens by means of a grin system 2 in which the first grid electrode has an opening which is non-rotationallysymmetrical, e.g. elliptical. The focusing lens 3 is rotationally-symmetrical. The gun 2 may be a triode gun or a tetrode gun, Fig. 4, in which the first grid 112 has an elliptical opening 128, the second grid 125 has a circular opening 129 and the accelerating electrode 113 is constituted by a spout-shaped portion of electrode 114 which forms with electrodes 115 and 116 the rotationally-symmetrical focusing lens 103. Due to the non-rotationally-symmetrical opening in the first grid the electrons appear to originate from two virtual, elongated crossovers and by matching the gun with the quadrupolar lens a circular beam spot is obtained on the target of the tube.

Title: Method of comparing a content in a storage register with the number of sheets of dispensed money in an automatic money dispensing machine
IPC: H03K21/08
Filed: 1971-12-29
Abstract: 1381120 Dispensing money GLORY KOGYO KK 29 Dec 1971 [29 Dec 1970 (2)] 60492/71 Heading G4X In an automatic banknote dispensing machine capable of dispensing a plurality of denominations the amount of money to be dispensed is registered in a shift register and as dispensation of the highest denomination notes proceeds the number of notes dispensed is compared with the contents on the most significant digit and the second most significant digit of the register, the contents of the shift register being shifted one digit higher when a coincidence signal is issued and the subsequent steps of dispensing lower denomination notes being controlled by comparison with the content on the second most significant digit of the register. The machines described may be selectively operated to dispense the registered amount in either the minimum possible number of banknotes or in banknotes of a selected denomination. In the embodiment shown the shift register MR, which for example has six digits, registers an amount, say 198,500 yen, to be dispensed with the minimum possible number of banknotes. On initiation of the dispensation operation 10,000 yen notes are dispensed, these being detected by detector R and counted by counter WR which has two decimal stages WR1, WR2. When the content in counter WR coincides with the content on the two most significant digits MR1, MR2 of the register (i.e. 19) the dispensation of 10,000 yen notes is ceased and a coincidence signal issued by comparator BC to automatic carry circuit CT thereby to shift the contents of register MR one digit higher. The number " 8 " is now registered on comparison reference digit MR2 and accordingly one 5000 yen note and three 1000 yen notes, followed by shifting of the contents of the register and then dispensation of one 500 yen note (the numeral " 5 " being registered on digit MR2 at this time). Two further shift instructions are issued to clear the register. The automatic carry circuit (Fig. 6, not shown) also functions to issue shift instructions to shift the first effective numeral in the register on to digit MR2 if the content on this digit is zero (e.g. when only 500 yen is registered two shift instructions will be issued) except when the content on the most significant digit MR1 is non-zero.

Abstract: 626,134. Electromagnetic ammeters and voltmeters. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. Aug. 22, 1946, No. 25084. Convention date, Nov. 3, 1942. [Class 37] In a measuring instrument a first moving coil is mechanically joined and series-connected with a second moving coil and one moves in a non-uniform magnetic field and the other in a uniform field or both coils move partly in a uniform and partly in a non-uniform field and in either case the electromagnetic torque is in the same direction throughout their range of movement. In Fig. 1 the coils co-operate with permanent magnet N, Z, and the smaller coil 2 moves in a field of uniform flux density and the larger coil 1 in a field which varies in strength throughout the range of movement of the coil. The difference in strength between the uniform field 5 and the field of steadily decreasing strength traversed by the coil 1 is so chosen that a prescribed non-linear relation is obtained between the current traversing the coils and the instrument deflection. In utilizing such a coil system for a lux meter to obtain a logarithmic scale of from 10 to 3000 lux, the magnet is of anisotropic Ni-A1 magnet steel to give a field strength of 1000 gauss in which the coil 2 moves and 2000 gauss for zero displacement and 200 for 90 degrees displacement of the coil 1. For torsional suspension of the movement the Specification gives the steps involved in calculating by means of graphs, Figs. 3 and 4 (not shown), the field strength required for various angular positions of the coil 1 to give the desired logarithmic characteristic. In a modified construction, Fig. 2, to avoid the coils crossing one another, two similar coils 9, 10 are arranged so that in rotation their inner sides remain in the field 5 of uniform flux density. In Fig. 1 the larger coil may at zero deflection occupy position 1<SP>1</SP> to obtain an angle of rotation of 120 degrees. It is stated that further coils may be added in Fig. 1.
