Title: Device for controlling the operation of a regulatable member
IPC: A01G25/16
Filed: 1973-09-11
Abstract: 1450794 Automatic control of flow valves MCJ LESTRADET 11 Sept 1973 [12 Sept 1972] 42612/73 Heading G3N [Also in Division H2]  An electric motor driven valve controlling the operation of a fluid sprayer is operated by a control system which responds to changes in the speed of the vehicle carrying the sprayer. In the arrangement shown the output voltage of unit 1 represents the speed of the vehicle and a manually set proportion of this voltage is passed by unit 2 to the motor control 3 to adjust the valve. The motor M is connected in a combined transistor/thyristor bridge arrangement so that it can be run in either direction. The thyristors Th1 and Th2 are fired by the voltage developed across resistors RGa and RGb respectively and the supply is switched by darlington connected transistor pairs T4, T5 and T4<SP>1</SP>, T5<SP>1</SP>. The motor drives the slider of resetting potentiometer P2 in a measuring bridge arrangement whose input comes from transistor Tl energized in accordance with vehicle speed. The control signals for the motor bridge circuit come from resistors RC and RE for the two directions of rotation.

Abstract: 945,848. Shaping uppers. GEO. KNIGHT & CO. Inc. Dec. 1, 1961 [Jan. 3, 1961], No. 43037/61. Heading A3B. A method of crimping a vamp 82 of a shoe upper comprises clamping the vamp 82 and an underlying protective cover 84, 86 centrally along a line while the edges of the vamp remain unsupported then simultaneously and progressively stretching the vamp 82 along lines on both sides and substantially parallel to the line of clamping. In the construction shown two identical jaw assemblies are carried by horizontal arms 20. An assembly comprises a wooden block 28 mounted between two frame members 24, 26 and resiliently mounted on springs 38 and a horizontal shaft 30, a heater 32 and shaped crimping jaw 34. The distance between the jaws 34 may be adjusted by nuts 46, locking device 48, and rotating cam 40 which also serves to vary the tension of springs 38. A blade 52 is mounted for vertical movement e.g. by pneumatic means above the gap between jaws 34. The shaped clamping edge 54 of blade 52 cooperates with a resiliently mounted clamping shoe 56 pivotally mounted on a support 58 to grip vamp 82 and protective cover 84, 86. The protective cover comprises a layer of leather 86 and a convenient number of rubber layers 84. Downward movement of blade 52 stretches vamp 82 over jaws 34, heat being then applied to the stretched vamp 82. Blade 52 and jaws 34 may have complementary recesses 37, 35 respectively to accommodate thicker parts of a vamp e.g. a vamp with a counter or lining attached. The upper end 57 of recess 55, at the maximum depression of blade 52, lies substantially in the plane of the top edge 36 of jaws 34.

Abstract: 1503228 Tool for applying a compressive force AMP Inc 17 Sept 1976 [22 Oct 1975] 43246/75 Heading B4C A tool for applying a compressive force to a workpiece comprises a working member 3, a back-up member 9 and means for urging working member 3 towards back-up member 9, the means including a rod 2 mounted for reciprocal movement towards and away from working member 3 which is mounted for reciprocal movement coaxially with rod 2, the rod being connected to working member 3 by a toggle joint link 4 comprising a link 51 pivotally connected to rod 2 and to a second link 6 which is also pivotally connected to working member 3, toggle link 4 having a projecting pin 20 at the connection point of links 5, 6, and a release member 15 reciprocally movable parallel to the path of rod 2 and having a surface 18 engageable with projecting pin 20 on upward movement to when link 4 is straight so as to urge the link to its bent position. Preferably the link is biased to its straight position by a torsion spring 22 and held in its bent position by the pressure of a projection 16 of release member 15 on a second pin 21 of toggle 4. A workpiece is placed over back-up 9 whilst the toggle is bent. A pneumatic or hydraulic cylinder 13 is operated to lower release member 15. Allowing toggle 4 to straighten. A second cylinder 1 is then operated to press working member downwards the force being transmitted via the straight toggle. Cylinders 1 and 13 are then operated to first raise member 3 and then bend the toggle link. As the link will only transmit a large force when it is straight it prevents damage to an operator's finger or other thick object erroneously placed over back-up member 9 as over sized will prevent the toggle from being straightened. Members 3, 9 may be a crimping die and an anvil, respectively, in order to crimp electrical terminals to electrical conductors, or a punch and a support respectively, in order to insert force fit electrical terminal posts in holes in a printed circuit board.

Abstract: 1286976 Welding by fusion DEGGENDORFER WERFT UND EISENBAU GmbH 2 Sept 1969 [31 Aug 1968] 43359/69 Heading B3R In a method for the automatic performance of a welding or other process, requiring a predetermined relative movement between a tool and a workpiece, wherein movements of the tool are controlled by two first control elements in two co-ordinate directions so that a compound resultant movement of the tool is automatically produced which is periodically repeated at various positions on a workplace, each individual resultant movement being in accordance with a predetermined curvature, and by second control elements which are locked periodically with respect to the workpiece and serve to compensate for possible inaccuracies in the location of successive working positions on the workpiece. Fig. 4 shows how this method can be used to weld tubes 5 to a tube header 4. A cyclic movement can be superimposed upon the main movement so that welding heat can be better dispersed. Figs. 1 and 3 show a machine capable of performing the method where the movement of welding rod 29 and the machine is controlled by cams 12-15. The machine runs on rails 3 fixed to the tube header 4 and has pins 6, 6<SP>1</SP> which in conjunction with a magnetic brake 7, locate the machine relative to the tubes 5. Another embodiment, Figs. 8 and 9 (not shown), describes how tubes that are irregularly spaced may be welded. The machine shown in Figs. 1 and 3 may be used for cutting sheet-metal utilizing a template, Fig. 10 (not shown). The control of any movement need not be only mechanical (cam discs), but may also be remote from the machine with electrical or hydraulic impulses fed to control members.
