Abstract: 946,756. Extruding. SCHLOEMANN A.G. June 21, 1960 [July 1, 1959], No. 21678/60. Heading B3P. An extrusion press has its die 9 and die holder 10 mounted in an arm 11 carried by a rotatable shaft 7 and movable axially to permit severing of the extruded product 37 between the die and press bolster 1, and a slide member 15 is provided on the bolster to prevent axial movement of the arm when necessary. The arm 11 has fork ends which carry a pair of exchangeable dies 9 and backing pieces 8, and is rotated by a pinion 32 on shaft 7 which is movable axially by a piston 30 in cylinder 31. A second arm 5 carrying a pair of pressure pieces 4 is mounted on a hollow shaft 6 surrounding the shaft 7. Shaft 6 may be clutched at 33 to pinion 32 for simultaneous rotation with shaft 7. Extrusion of a billet from container 28 is performed by a piston in doubleacting hydraulic cylinder 41; the die and container are then in their extreme left position, Fig. 2 (not shown), with the arm 11 located axially by slide 15, which is actuated by piston 17 in cylinder 16, and the shaft 7 by slide bars 35. After extrusion the slide bars 35 and the slide 15 are withdrawn, the container is moved to the right by piston 44 in cylinder 45 and the arm 11 with the dies is moved to the right by piston 30. The extruded product is then severed by a saw 36, the container and die again moved to the left and the slide bars 15, 35 reinserted. Finally, the container only is moved to the right to separate itself from the die. Specification 946,757 is referred to.

Title: Improvements in moving figure toys
IPC: A63H13/10
Filed: 1953-08-12
Abstract: 735,403. Moving figure toys. WELLS & CO., Ltd., A., and WELLS, A. W. J. July 16, 1954 [Aug. 12, 1953], No. 22223/53. Class 132(3). A toy representing a marksman has remote control for causing the figure to withdraw a pistol from its holster, bring it to the firing position and thereafter to return the pistol to the holster, a cap-firing mechanism operable by remote control also being provided. An arm 17 of a figure 10 is normally maintained by gravity in a position such that a pistol 14 is in a holster 15, the lower end of an arm operating rod 25 resting on the low part of a cam 24 formed on a quadrant 21. A pin 28 (Fig. 5) on the underside of the quadrant is engageable with a pawl 37 which operates a cap feed pawl 33 and a firing hammer 35. Upon pressing the trigger of an actuating pistol connected by Bowden cable to the mechanism in the base 11 of the figure, the quadrant 21 is rotated, and a cap is fired simultaneously with the raising of the figure's arm by the rod 25 and cam 21. In a modification, Figs. 8 and 9 (not shown), remote controls are provided to enable two arms of the figure to be operated independently. Alternatively the two arms and the cap-firing mechanism may be operated by a single remote control. In a further modification, Fig. 10, the pistol and arm are separate and the pistol is "drawn" as the result of attraction between magnets 55, 56 when the arm 17 is moved by means of an actuating trigger 116 from its normally raised position downwardly and rearwardly past the holster 15. Attraction between the magnets then causes the pistol and lower part of the arm 17 to become aligned, and release of the trigger 116 allows spring means to urge the arm 17 to the raised position, the pistol being guided past the holster by a lip 57. After the cap-firing mechanism has been operated by an actuating trigger 16, the trigger 116 is again pressed and the arm 17 moves to the rear, the front of the pistol dropping into the holster via a slot formed in the front thereof. Release of trigger 116 then allows the arm to move to its normal raised position, the pistol being trapped in the holster. The pistol may be attachable to the arm by means of an eyelet engageable by the arm.

Title: Improvements in or relating to automatic flight control systems
IPC: G05D1/08
Filed: 1948-02-28
Abstract: 715,333. Automatic aircraft control systems. SPERRY CORPORATION. Feb. 28, 1948 [March 15, 1947], No. 22280/51. Divided out of 715,312. Class 38(4) An aircraft may be caused to execute banked turns by either the automatic adjustment of the bank angle in accordance with a predetermined rate of turn or the adjustment of the rate of turn to correspond to a given bank angle; a spiral turn can also be effected. As shown, the output from flux valve 37 is, during straight flight, applied through the differential selsyn 44 to the input of computor 18 and the craft is steered automatically along a predetermined course. The ailerons are operated by a signal generated at the pickoff 63 operated by gyro 62 which is precessed by torque motors 61, 61<SP>1</SP>. Motor 61 is energized by a signal proportional to the difference between the craft bank angle detected at the pick-off 24 of gyrovertical 23 and the required bank angle as derived by computor 18 from the predetermined rate of turn applied at knob 11. Motor 61<SP>1</SP> is energized by a signal proportional to the product of the angle of elevation, derived at sine selsyn 58 and the predetermined rate of turn derived from 12. Rudder operation is effected by pick-off 75 of gyro 74 precessed by torque motor 73 energized by the predetermined rate of turn signal generator at 10, through the cosine selsyn 68 on the pitch axis of gyro 23 and through cosine selsyn 64, on the roll axis. The elevators are similarly controlled from pick-off 85 by gyro 84 precessed by torque motor 83 energized through cosine selsyn 78 and sine selsyn. 65. A climbing turn is initiated by movement of 12 about axis 86 and a signal produced at 87 is applied to the rudder and elevators via selsyns 91, 94, 95. At the computor 18 signals proportional to the predetermined rate of turn and the airspeed are applied to a cosine selsyn on the pitch axis of 23 the output from which is applied to a device producing an angular displacement the tangent of which is proportional to the product of the applied signals. Short period control of the aircraft is effected by the gyros 62, 84, 74 and only if persistent errors are developed do the signals from the gyro-vertical 23 effect control. During steady flight the potentiometer 100 is shorted out and no signals are applied to 61 from 23. In the alternative arrangement (not shown) the control knob may be operated to give a predetermined angle of bank and elevation; upon a given bank angle signal being applied to the ailerons, a selsyn operated by the gyro vertical supplies a signal to a computing device, the output of which is proportional. to a rate of turn which corresponds to the predetermined bank angle and which is applied to the rudder control system. The torqued gyros in both embodiment may be replaced by accelerometers.

Title: Improvements in or relating to electrical control systems
Inventor: JENKINS WALTER NORMAN
IPC: B30B15/14
Filed: 1958-07-11
Abstract: 874,910. Control of motors; controllers. BRITISH IRON & STEEL RESEARCH ASSOCIATION. July 13, 1959 [July 11, 1958], No. 22307/58. Class 38 (3). Relates to a control system such as that described in Specification 874,908 in which the upper and lower limits of movement of a pressmember for forging are determined by the settings of potentiometers from which voltages are selectively derived for comparison with a voltage obtained from a potentiometer, the position of whose slider corresponds with that of the press-member. The error-voltage is applied to a polarized relay for controlling the upward and downward of the press-member, a tachometer generator providing a feed-back voltage proportional to the speed of the pressmember for preventing under-shooting or over shooting of the limiting positions. As shown, the lines 12 are connected across the tachometer generator whilst terminals 17, 18 are in circuit with the polarized relay, the effective portion of the feed-back voltage being derived from wipers L1, M1 of uniselector switches driven by motors L, M and associated with potentiometer 13. If over-shoot occurs, a pulse is applied to terminal O and the motor L and the wiper L1 is moved one step to increase the feedback signal. Whereas, if under-shoot occurs, a pulse is applied to terminal U and the motor M moves the wiper M1 one step to decrease the feed-back signal for a given velocity. When the wiper L1 reaches the last of the contacts 15 in the clockwise direction, both motors L, M are intermittently energized and the wipers L1, L2 and M1, M2 are stepped around until wiper M2 reaches contact 21. The wiper M1 is thus brought to the first of the contacts 16, the spacing of the contacts L1, M1 being equal to that existing before the stepping action. The polarized relay controls contacts 22 in accordance with the direction of the detected error and, if over-shoot occurs, when the forging member is moving downwardly, relay DR is de-energized and relay U is energized. Relay Q becomes energized to close contacts Q1 so that, when push-button PB is actuated to start a next control operation, a circuit is completed to terminal O for a short period, relay T being then energized to break the holding circuit of the relay Q. This has the effect of pulsing the uniselector motor L. If over-shoot does not occur, the relay Q is not energized and, on closure of the push-button, a pulse is applied to terminal U for energizing the uniselector motor M. When the condition for proper functioning of the control system has been reached, the effective number of resistors in the chain 13 is increased and decreased by one on alternate operations of the push-button PB.
