Patent ES-333683-A1 (ES)
Title: System to automatically control gage and the like
IPC: B21B1/32
Filed: 1966-11-23
Abstract: A transverse dimension of a workpiece is reduced by passing it longitudinally through a machine in which the degree of reduction is automatically controlled in dependence on deviations of draft ratio and input thickness to maintain an output dimension of the workpiece substantially constant. In Fig. 1, material 7, uncoiled from a mandrel 5, passes through reversing rolls 4 and is re-coiled on a mandrel 6. Electrical pulses produced by generators 12, 13 driven by travel of the material before and after rolling are applied to a comparator 18 the output signal of which, on line 23, corresponds to deviation of the draft ratio from a datum value determined by a signal applied to line 19. A radiation or contact gauge 8 produces a signal, corresponding to deviation of ingoing thickness from a datum value, which is delayed by a unit 15 for a time equal to that required for the material to move from gauge 8 to rolls 4. This delay is produced in unit 15 by causing pulses from generator 12 to operate stepby-step switches which periodically charge condensers and later transfer those charges to the output circuit. The draft ratio and delayed ingoing thickness deviation signals are respectively amplified at 24, 21 and modified by potentiometers 25, 22 set in accordance with the datum values of ingoing thickness and draft ratio so that when combined in an integrating amplifier 30, a signal is produced representative of outgoing thickness, variations of which are then automatically corrected by control of an electrically or hydraulically operated roll separation adjusting device 3 of the wedge or screw type. Filtered signals from a further thickness gauge 9 may be applied to amplifier 30 to ensure greater accuracy in maintaining outgoing thickness at a desired value. A more accurate prediction of outgoing thickness may be obtained by also applying the product of the draft ratio and ingoing thickness deviation signals to input terminal C of amplifier 30. Correction may be effected by automatic control of mandrel drives 28, 29 instead of or in addition to roll separation. Application to tube drawing is referred to.

Title: Intermittent drive mechanism having self-compensating means for offsetting the effects of developed countertorque
IPC: C03B5/167
Filed: 1968-01-22
Abstract: In a variable ratchet drive, particularly for an unloading conveyer of a motor truck or trailer, wherein a driven member is periodically moved stepwise by way of a one-way clutch and prevented from back-running by a one-way brake, and wherein the non-driving return stroke of the driving member of the clutch is limited by a manually adjustable abutment to vary the driven member stroke, load-variable driven member stroke loss, due to transmission resilience particularly in the clutch and brake parts, is compensated for, and hence driven member stroke (e.g. conveyer feed) for a particular manual setting thereof is rendered substantially uniform irrespective of load, by mounting the reaction member of the one-way brake so as to react against spring means and using the load-variable periodic reaction movement of said reaction member to effect a periodic overriding movement of the adjustable abutment to render the non-driving return stroke of the driving member proportional to the driven member load. The one-way clutch and brake may be linear or, as shown, rotary. As shown, a cam 11 keyed on an input shaft 4 acts on a follower roller 13 rotatably mounted on a spring-returned bell-crank lever 14. The latter, in turn, is connected by parallel links 18 to the driving outer race 22 of a one-way clutch the driven inner race of which is keyed on an output shaft 26. The inner race 24 also forms the rotatable member of a one-way brake having a reaction outer race 27. The one-way clutch and brake have tilting or rolling gripping means 23, 28. The reaction outer race 27 is pivotally connected at 30, 31 to one arm of a three-armed lever 32 having a second arm 34 engaging a stack of Belleville spring washers 36 via a guide pin 35, and a third arm 37 pivoted to a plate 39 guided by a screw-pin and slot 40, 41. The manually adjustable abutment limiting the non-driving return stroke of the follower roller 13 and the driving outer race 22 is provided by an abutment cam 42 adjustably rotatable, via a tube 5 welded thereto, between limits defined by cam edges 43, 44 and the screw-pin 40. The plate 39 surrounds the tube 5 such that on load-variable periodic reaction movement of the reaction outer race 27, the lever 32 and the plate 39, the Belleville washers permitting greater movement with greater reaction load, the tube 5 and hence the abutment cam 42 are moved leftwardly back to increase the non-driving return stroke. The tube 5 may be rotated by a pulling means engaging a wheel of the tube, by a pair of such pulling means oppositely directed for operation from more than one station, or, shown, by a hand wheel (9) adjacent the driver's seat and acting through worm gearing 7, 6.
Patent ES-358699-A1 (ES)
Title: Article dispensing apparatus with selectively releasable hinged shelves
IPC: A47F3/026
Filed: 1968-10-02
Abstract: An article dispensing apparatus comprises a plurality of vertically aligned shelves 13, each mounted on a rod 16 for rotational movement from a horizontal article-supporting position to a vertical non-supporting position, each shelf being latched horizontally by a pin 22 extending laterally therefrom received in a partition aperture 25. A control bar 40 provided with an actuating arm 41 for each shelf initially has its lowermost arm 41C supported on pin 22 of the lowermost shelf 13C, its next arm 41B spaced a distance H above its pin 22 and the nth arm 41 spaced a distance (n - 1)H above its pin. During the first cycle, bar 40 oscillates and arm 41C pushes a flange 14 on the shelf 13C against a spring (20, Fig. 1), so that pin 22 is released and the shelf 13C falls to its vertical position (see Fig. 3). Bar 40 then drops down till arm 41B rests on its pin 22, and shelf 13B is released during the next cycle. After the top shelf 13A is released, bar 40 falls until a portion 44 thereof engages a stop 51. For dispensing tall articles, one or more of the intermediate shelves may initially be vertical (see Fig. 4), and after releasing the lowermost shelf, the bar drops down till one of its arms rests upon the pin of the next higher shelf that happens to be in the horizontal position. Bar 40 is oscillated by a solenoid switch 47 which moves a clamp 46 mounted on and offset portion 45 of the bar, horizontally, and a return spring 50 is provided. Between each pair of shelves is a deflector arrangement comprising integral rear and side deflectors 30, 31. The rear deflector 30 extends above the shelf below when the latter is vertical to prevent articles falling from a shelf above from hitting a lower shelf or shelves the side deflectors 31 prevent articles falling from a shelf above from hitting the actuating arms 41 associated with the lower shelves, and the arms 41 from engaging articles on the shelves during horizontal movement of the arms on oscillation of bar 40.

Title: Electrical connections for pairs of conductors
IPC: H01R4/18
Filed: 1968-10-03
Abstract: A connector 14, Fig. 9, connects two pairs of insulated telephone circuit wires, the operation being carried out in the crimping apparatus shown in Fig. 1. The connector similar to that of Specification 1,045,380, comprises two metal crimping ferrules 16, 18 formed with pressedout sections 30, 34 to give a preferred axis of bending A-A and tongues 26 pressed-out from the base 20 forming notches 28. The ferrules 16, 18 are insulated from each other by a film 40 of insulating material such as polyethylene terephthalate, bonded to the outside ferrule surfaces. The crimping apparatus comprises two block members 48, 481 slidably mounted on guide rods 52 and urged apart by springs 56, 561. Both ends of a guide bar 74 of a connector support and wire cutter member 75 are spring-loaded in bores provided in the blocks 48, 481. When the blocks are moved together the cutting blades 72, 721 recede into slots 70, 701 and the arms and slots 50, 501 interlace to bring a pair of die cavities 60, 601 into direct opposition. In operation, the support member 75 receives a connector, the arms 72, 721 locating in the slots 37 so that two ferrules 16, 18 face towards the die cavities 60, 601. The pairs of wires approach from opposite faces of the member 75 and the individual wires are laid in the die cavities 60, 601 with their ends turned into the slots 70, 701. When the two blocks 48, 481 are drawn together, by means of tool handles or a power driven tool head, the wires are sheared as cutter members 72, 721 enter the slots 70, 701 and the connector is engaged by die surfaces 60, 601 causing wall sections 22, 24 to curl over on to the wires. The wires impinge on the edge of notches 28 which pierce the wire insulation. In a further embodiment of the connector, the ends of the base portions of the insulating covering extend beyond the sidewall portion. These tongues may be gripped during the crimping operations to reduce the likelihood of bending along the axis of the connector.

Title: Coin roll dispensing and boxing apparatus
IPC: B65B35/40
Filed: 1968-10-05
Abstract: A coin roll handling machine for boxing coin rolls 22 comprises a coin roll shoot 10, a gate 32 to retain coin rolls in the shoot, a coin roll accumulator 14, and a pusher 12 to supply rolls to the accumulator. The rolls collect behind the gate until a roll is resting on a microswitch 26 to operate a four-way valve through a delay switch and supply air to a double-acting cylinder 56. The pusher 12 is thereby moved rightwards to release a microswitch 86 energizing a three-way valve to raise the coin gate 32, and deposit a predetermined number of rolls on a vertically movable platform 76. The rolls actuate a microswitch 72, causing the platform 76 to rise, and the rolls, projecting at both ends over the respective edges of the platform, force upwards two pivoted spring-loaded flaps 92. When the rolls have cleared the flaps the flaps swing out under the rolls to support them as the platform 76 is lowered. A cam 94 closes a microswitch 74 to reverse the four-way valve, causing the pusher 12 to return leftwards. The microswitch 86 is re-engaged to close the gate 32. The rolls which have been resting on top of the pusher move to refill section 20 of the shoot. The above operation will be repeated until a microswitch 70 is actuated by the top layer of rolls accumulated, causing a ram (78), Fig. 5 (not shown), to push the rolls into a box (80) on a conveyer (16).

Patent ES-395290-A1 (ES)
Title: Anti-skid braking systems
IPC: B60T8/58
Filed: 1971-09-06
Abstract: An anti-skid braking system has a generator driven by a wheel of the vehicle for producing an alternating output with a frequency proportional to wheel speed. This signal is converted to a voltage level and differentiated to produce a signal representing deceleration. A control circuit modifies the brake pressure in accordance with the output from the differentiating circuit to minimise risk of locking of the wheel, and a capacitor which is charged by the output from the differentiating circuit is connected to the control circuit. This capacitor has a permanent discharge path and the control circuit responds to the capacitor voltage or the output from the differentiating circuit, which ever is higher. The overall effect is that the braking pressure is increased more rapidly on a good road surface than a bad road surface.
