Title: Automatic strip threading device for a tandem mill assembly
Inventor: LYLE DAVID
IPC: B21B37/68
Filed: 1963-10-28
Abstract: 992,101. Rolling. BLAW-KNOX CO. Oct. 28, 1963, No. 42381/63. Heading B3M. A tandem strip mill assembly is provided with an interstand threading guide frame having guides on each side of the path of strip travel, and sensors on the guides, such that when the strip moves from the centre-line of the mill the sensors are moved and thus actuate the preceding stand to differentially charge the roll pressure on opposite sides of the stand to cause centering of the strip. The leading end of a coil 10 is unwound at 16 and is fed past pinch rolls 19, guides 23, rolls 27 of a first stand 24, and to a tensiometer 28 of a threading guide 29. The guide 29 has sideguards 30 and 31, shown in plan, Fig. 3, which contain vertical rollers 36, converge towards the left and are adjustable symmetically about the mill centre line by screws 34 and 35 driven through gearing from a motor 32, and are held in position by cylinders 37. Attached to the sideguards are sensors 38 of the variable transformer type, for example, whose outputs are fed to actuators for varying the roll pressure on opposite sides of the first stand 24 to cause centering of the strip. Load cells 43, Fig. 2, on the stands sense the pressure of the strip and cause opening of the sideguards when the strip reaches the second stand, and resetting of the sideguards when the tail end of the strip has passed the second stand. The threading guide can be raised and lowered by an hydraulic cylinder 45 and can be moved laterally clear of the stand. The guides 23 have separable halves operated by hydraulic cylinders 25 and scissor mechanisms 26. The coil 10 before rolling is carried on a conveyer 1 between centering guides 11, is supported on adjustable rollers 17a and 17b while the leading end is separated by a picker blade at 16, and is transferred without rotation to rollers 18a and 186 where it rests during rolling. The coil opener at 16, and also a coil box 18 holding the coil, can be moved transversely of the rolling line by hydraulic cylinders.

(Fig. 4(e)) to form an output sawtooth of lower frequency. The switching circuits 74-81 are arranged as changeover switches which alternatelyconnect the network to the voltage 70 and the zero voltage 71. The constant voltage source may be replaced by a constant current source (Fig. 5 not shown) with a different resistor network. The networks shown require a very high load impedance; therefore if the circuits are to be cascaded an impedance transforming circuit is connected to the output. Several circuits are described (Figs. 13-19 not shown and Fig. 20) having input impedance up to 100M# and outputs of less than 1k#. The resistor network 65, the switching devices 74-81, the dividers 61-64, the impedance transforming circuits (Figs. 13-20 not shown) and also gating circuits for indirect keying of the electronic organ all employ MOSFET's and may be integrated on a single chip (Fig. 14 not shown).

Title: Vending machine
IPC: G07F11/58
Filed: 1962-11-09
Abstract: 1,002,360. Coin freed apparatus. SEEBURG CORPORATION. Nov. 9, 1962 [Aug, 14, 1962], No. 42494/62. Heading G4V. A vending machine stores articles 47 in a number of parallel rows supported on each side of support bars 38 extending between endless chains 35, the articles being lowered two rows at a time on to slides 16, 16a from which they are dispensed by being pushed one at a time to a delivery point. As seen best in Figs. 11 and 13 the slides 16, 16a comprise rails with a U-section top portion in which endless chains 18, 18a lie. Each chain has a pusher 48, 48a, both chains being driven by the same motor (not shown) and the pusher of one slide dispensing articles on that slide one at a time while the other pusher returns beneath the other slide. When both slides have been cleared of articles the last re-   turning pusher 48 engages an arm 55, Fig. 13, to operate a switch 51 causing the chains 35, Fig. 11, to lower two fresh rows of articles on to the rails. As the support bar 38, on which the fresh rows are carried, deposits its load on to the rails it actuates an arm 57, Fig. 13, to restore the switch 51 and halt drive to the chains 35. Drive to the motor operating the pushers 48, 48a is connected at command of a coin mechanism (not shown) and a selector button if a number of dispensing units are employed to handle different articles. As the article dispensed is propelled into a delivery bin it breaks a light beam to a photo-electric cell to halt the motor. To prevent fraud by shining a light on to the cell and consequently collecting all the articles on the slides, a second cell is provided off the light beam to the first cell so that the drive may be disconnected at once if any other light source intrudes. As shown in Fig. 14, the chains 35 between which the support rails 38 extend are made to run in U-sectioned channels 63 on the downward side of the chains. One of these channels has an associated slotted channel in which rod 61 slides. Connected to rod 61 by a pin 68 is a pair of spring fingers 69, see also Fig. 15, which are placed beneath the first empty support rail 38. When the last load of articles is deposited on the slides 16, 16a, the rod 61, Fig. 15, operates a switch 60 to disconnect the delivery mechanism and light an empty indicator. The last rows of articles are not delivered until the machine is reloaded and the rod 61 slid upwards to the first empty support bar 38. This arrangement is employed because the articles are refrigerated within the machine and while the cold articles left over from the previous loading are being dispensed the new articles have time to cool. The support bars 38 are detachably secured to the chains 35 so that articles of different sizes may be catered for with an appropriate spacing between the bars. A relay control circuit is described with reference to Fig. 20, not shown.
