Abstract: 1,041,319. Mechanical calculators. T. KAGITANI. Nov. 19. 1964 [Dec. 27, 1963], No. 47187/64. Heading G4B. Pawls 6 (Fig. 2) which arrest the rotation of a plurality of toothed sectors 3 constantly meshing with adding racks 1 are controlled by solenoids 10 connected to the electronic circuit of a calculating unit, the solenoids acting directly for numerical values 1 to 3 and through a relay and delay device for values 4 to 8. In the form shown, rotation of one of the toothed sectors 3 (Fig. 3, not shown), effected by the rack 1 when one of the keys 49 (Fig. 8, not shown) is depressed, results in the rotation of a contact gear 11 carried on the same shaft so that a printed contact 17 contacts a printed circuit 19 and the numerical values are transmitted to a calculating unit. The results are sent out electrically when a call signal appears, the number 1 being transmitted when current is supplied to the solenoid 10b (Fig. 2), so that the pawl 6b engages the detent 5b to arrest the rack. The numbers 0, 2 and 3 are similarly transmitted. To transmit the number 4, the actuation of the solenoid 10a is delayed via cam operated switches and relays so that the pawl 6a passes the end of the tooth 5a and engages the detent 5b. The numbers 5, 6, 7 and 8 are similarly transmitted. The decimal memory unit has no numerical value corresponding to the number 9 and therefore, since no current will flow in any of the solenoids 10, the pinion 3 turns to its full limit to transmit this number. The results are printed by a type-bar 61 (Fig. 8), controlled by the movement of the rack 1.

Filed: 1972-10-16
Abstract: 1393569 Measuring force electrically USS ENGS & CONSULTANTS INC 16 Oct 1972 [14 Oct 1971] 47643/72 Heading G1N [Also in Division H4] A storage cathode-ray oscilloscope 18 (Fig.2) displays the roll separating force in a metal rolling mill 2 (Fig.1) during the forward trace between positions A and B and during the retrace the vertical height of the position C to D is set to indicate the maximum permissible force. This enables the operator to speed-up the operation by increasing the roll force to just below the permitted level. As shown, a strain gauge bridge 8 supplies, via output 48 of a drift compensator 16, a signal proportional to the roll separating force and with the switch contacts in the position shown, this signal is fed via contact 40C3 to the vertical deflection plate 26 of the oscilloscope to deflect the beam as it is swept horizontally by a sweep voltage derived from a generator amplifier 36 and connected via potentiometer 30 to the horizontal deflection plate 22. The speed of the forward trace of the latter may be adjusted by means of potentiometer 44 connected to a -10V line L1 and the retrace speed may be adjusted by means of a potentiometer 42 connected, when contact 40C2 is closed, to a +10V line L2. The output of the sweep circuit 36 is also fed to a comparator 38 which receives a second input via contact 40C from the -10V line L1 and the arrangement is such that when the beam is at position B the output of the sweep circuit is +10V and this together with the second input of - 10V is stated to cause relay 40 to operate and to change over the contacts from the position shown. In this condition the input to the vertical deflection plate 26 is replaced by an adjustable voltage from potentiometer 46 which sets the level of the retrace position C to D which indicates the maximum permissible force, the pre-set retrace speed control potentiometer is supplied from the +10V line L2, an erase circuit 52 is operated, a reset circuit 62 is operated by a signal on line 54 indicative of the presence of a work piece in the mill and the closing of contact 40C 1 allows the comparator 38 to again energize the relay 40 to restore the contacts to the position shown when the sweep output has reached zero, indicative of position D.

Title: Improvements in and relating to electrical connections in printed circuit boards
IPC: H01R12/52
Filed: 1964-11-30
Abstract: 1,015,827. Printed circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 30, 1964 [Dec. 23, 1963], No. 48526/64. Heading H1R. In a method of forming a conductive connection between conductive sheets 12, 14 clad on opposite faces of a dielectric sheet 10, an aperture is produced in sheet 12 by a photo-etching process, then a registering aperture is etched in sheet 10, after which a layer 22 of copper is electrolytically deposited on layer 12 and inside the apertures, wherein it contacts the inner surface 20 of layer 14. The area to be electroplated is first seeded with an electroless deposit of palladium chloride, and the copper may be coated with silver, nickel, lead-tin solder &c. Subsequently, desired circuit patterns are formed in layers 12-22 and 14. When dielectric layer 10 is of polyethylene-terephthalate, or phenolic or epoxy material, hot concentrated sulphuric acid is used to etch the aperture therein; the glass fibres in epoxy glass require hot concentrated sodium hydroxide o hydrofluoric acid as etchant. When multilayer circuit boards are used, undercutting of dielectric layers is minimized by etching each layer independently with intermediate rinsings. Instead of plating the apertures, solder balls may be inserted and applied by heating. To etch a hole in a dielectric sheet having one surface only conductor-clad, the unclad surface is masked, except at the site of the hole, with a metallic resist.

Abstract: 1,149,992. Breaking open cartridges. EASTMAN KODAK CO. Oct.26, 1967 [Nov.3, 1966], No.48759/67. Heading G2A. The invention provides a fixture for breaking open a plastic film cartridge of the expendable type, and extracting the spool of exposed film therefrom. In the form shown, the fixture comprises a vertically mounted support 35, having a vertical guideway 36 down which the cartridge 10 is slid. It is guided by a pair of members 38, passing between spacer plates 37 which are cut back at 39 to facilitate insertion. Two pivotable support members 42, turning on pins 41, are secured on the spacer plates. These support members have projections 44, 45 and when they are positioned as in Fig.1, the fixture is ready to receive a cartridge. The cartridge passes between the projections 44, which are drawn back clear of the cartridge and engages the projections 45. The members 42 are thus pivoted round so that the projections 44 engage in the hollow core 24 of the take-up spool 16, Fig.2 (not shown) and form a pivot on which the cartridge can turn. It is now in the upright position of Fig. 3 (not shown), and the operator then forces it in a clockwise direction, through the position shown in Fig. 5, until it is horizontal. During this movement, a projection 31 moulded at the take-up end of the cartridge engages against the sharp edge 55 of a fixed breaker member 56. This ruptures the chamber containing the take-up spool. If the cartridge has been made in two separate halves, sealed together along a central join 13, completion of the turning movement will rip the cartridge apart along the sealing line 13. The end of the film can now be grasped and unwound from the spool 16. The entire operation may conveniently be carried out in the dark.
