Abstract: 1,133,437. Shaft encoders. VEEDER INDUSTRIES Inc. 13 Dec., 1966 [17 Jan., 1966], No. 55723/66. Heading G4H. A shaft encoder giving a four bit binary coded output comprises a coded disc (Fig. 5) sensed by three brushes 34, 36, 38 (Fig. 1), rotating with the shaft 24 and laterally displaced from each other. In the embodiment described a number wheel 26 on the outer surface of which are decimal numerals is stepped via gears 22, 23 each time a counting pulse is applied to solenoid 10 to rotate a ratchet wheel 20. As the wheel 26 rotates, brushes 34, 36, 38 are moved over conducting segments on the coded disc, a further brush 32 moving over a continuous conducting portion 54. The conducting segments are connected to lines 58, 66, 74, 82, 90 (Fig. 5), electric current being supplied on line 58 so that a binary coded indication is given on lines 66, 74, 82, 90 of the position of the shaft.

Abstract: 1,121,784. Measuring surface friction properties of webs, electrically. CROWN ZELLERBACH CORP. Dec.20, 1966 [Jan. 3, 1966], No.56970/66. Heading G1N. An apparatus for continuously measuring the surface friction characteristics of a moving web (eq. polyolefin film) comprises means for feeding a reference strip 13 from a supply roll 14 at a constant velocity, means including a solenoid 35 and lever system 32, 33 for urging the strip 13 into contact with the moving web 11 to be tested, and means including a differential transformer 31 for measuring the relative frictional force produced between the strip and the web. The strip 13 is driven by a motor (not shown) coupled to a roll 16 and its contact pressure against the web 11 may be adjusted by placing weights on beams 22, 25. In operation the web is driven at several hundred feet per minute and the strip 13 is driven at a constant speed of approximately one inch per minute in the same direction. The friction developed between the engaging surfaces of the web and strip tends to move beams 22, 25 to the left the beams being free to move by virtue of their pivotal support by links 23, 32, 33 and by the action of a cantilevered spring arrangement 26. In moving to the left a cone of the differential transformer is also moved producing an electrical signal proportional to the relative frictional force which signal is fed to an indicator or recorder. The apparatus may for example be used to measure the degree of surface treatment of polyethylene film by an electrical corona discharge. The reference strip may be of paper, film or foil.

Abstract: 1307948 Arc heating; electroslag remelting apparatus COMBUSTION ENG Inc 9 Dec 1971 [10 Dec 1970] 57336/71 Heading H5H [Also in Division B3] In an electroslag refining process the slag is melted in a mould 12 and is then passed through a passageway 30 to a mould 14 in which a consumable electrode 50 is to be melted. The moulds rest on split copper plates 16 and 18 having a layer of refractory material between them. The slag is melted by a water-cooled non-consumable electrode 32 having a tungsten tip 42. An arc is struck between the tungsten tips 42 and 44 to melt the slag, a voltage control mechanism being operative during the initial stages of the process and a current control mechanism becoming operative when a sufficient amount of slag has been melted to provide a path for current flow. After the slag has been melted the mould 12 is moved to the right to allow the slag to flow through the passageway 30 into the mould 14. Power is supplied to the electrode 50 before the slag is admitted to the mould 14 but no current flows until the slag bridges the gap between the electrode and the base-plate 18.

Abstract: 1281413 Valves; fluid pressure brakes BENDIX CORP 28 Nov 1969 [27 Dec 1968] 58379/69 Heading F2F and F2V [Also in Divisions G1 H1 and H2] A three-way valve device controlling the flow of fluid pressure to a motor is controlled by the output from a variable frequency pulse generator. In an electro-hydraulic braking control system for a tractor-trailer type vehicle, Fig. 1, solenoid 62 operated three-way valve 54 controlling the fluid pressure to conduit 58 feeding the wheel brake actuators is operated in accordance with the average value of saw-tooth pulses on line 66 from electro-magnetic vibrator control device 10, Fig. 2. The vibrator 10 comprising armature 96, contact 100, core 94 and coil 92 energized from battery 32 vibrates at a frequency determined by the return force of spring 102 loaded by a further spring 108 in engagement with pivotably mounted hand lever 12, whereby movement of the lever 12 alters the loading of spring 102 and thereby the frequency of the vibrator. Hand lever 12 is provided with a roller 120 abutted by transmitting lever 118 controlled by rod 116 and piston 114 responsive to fluid pressure in conduit 14. When brake pedal 19 is depressed the increase in fluid pressure from brake cylinder 18 in conduit 14 results in the pivoting of lever 12 to decrease the load on spring 102 and decrease the output frequency of the vibrator. Coil 64 of valve 54 is thus de-energized so that spring 72 biases rod 70 to the left to close the connection between chambers 82, 84 and to open the connection between chambers 80, 82 until the fluid pressure force on sleeve 88 balances the resilient force of spring 72 minus the magnetic force on core 70 as controlled by coil 64. When the brake pedal is released the loading on spring 102 increases to increase the output frequency of the vibrator and thus the energization of coil 64. Rod 70 thus moves to the right to connect chambers 82 and 84 and disconnect chambers 80, 82 to allow fluid to flow to reservoir 46. Coil 122 provided on the vibrator is energized by the vehicle stoplight system 40, 42, 44 to decrease the energization of coil 92 to decrease the frequency of the output signal upon initial displacement of the brake pedal 19. In an alternative form of vibrator, Fig. 3 (not shown), the rod 116 connected to piston 114 passes through the control lever 12 and is in line with spring 102.
