Filed: 1975-09-30
Abstract: 1485486 Conveying fluorescent light tubes GENERAL ELECTRIC CO Ltd 30 Sept 1975 [30 Sept 1974] 42372/74 Heading B8A Fluorescent light tubes 5 are transferred from grippers 8 on a rotating turret 1, to similar grippers 8a on an endless conveyer 2. Each gripper 8, 8a, comprises a seat 5 for the tube, and a pair of gripper arms 12 each carrying a roller 14, both rollers being urged into engagement with the tube 5 by a spring 13. As the path of the turret 1 moves adjacent the path of the conveyer 2, the tube 5 held in the grippers 8 engages the rollers 14a of the grippers 8a and thus snaps into engagement with the latter while still being held by the grippers 8 (the grippers 8 are laterally offset relative to the grippers 8a). On further movement of the turret and conveyer such that the gripper 8 starts moving away from the gripper 8a, the tube snaps out of engagement with the gripper 8. This is due to the angle taken up by the gripper 8, but may be brought about alternatively by, either providing a stripper member 21, or by making the spring 13 weaker than the spring 13a. The conveyer 2 may alternatively be a turret of greater radius than the turret 1.

Title: Improvements in static electric converters
Inventor: ANDERSSON JERKER
IPC: H02M7/757
Filed: 1969-08-28
Abstract: 1,270,310. Static converter control systems. ALLMANNA SVENSKA ELEKTRISKA A.B. 28 Aug., 1969 [29 Aug., 1968], No. 42789/69. Heading H2F. Relates to a rapid re-starting arrangement for a static converter 1 (Fig. 1) connected between an A.C. system and an HVDC transmission line, after it has been blocked by a blocking device 12 (e.g. part of a protection means for the D.C. line 4), the arrangement ensuring rapid increase in the D.C. voltage without overvoltage and including means whereby after blocking is removed an increased signal is applied temporarily to the input of a control amplifier 5 controlling a pulse delay angle control unit 6 and control pulse generator 7 thereby to reduce the control pulse delay angle. Blocking.-The maximum output voltage from amplifier 5 causes minimum delay angle α and maximum positive direct voltage output from the converter. Minimum output from the amplifier gives maximum control angle i.e. towards 180 degrees. The blocking device 12 thus operates on the input to amplifier 5 through a switching member 14 (e.g. transistor or relay) to apply a positive voltage to the input which predominates over other inputs whereupon the amplifier output decreases toward zero. Control device 6 then increases the delay angle toward 180 degrees so that the rectifier tends toward inverter operation and its D.C. output becomes zero. Alternatively the blocking means may operate to disconnect the pulse generator 7. Rapid starting.-When the temporary blocking is removed the control amplifier output increases. The increase is damped however due to the time required to re-charge capacitor 11. To reduce this time the input to the amplifier is temporarily increased by connecting it to a more -ve point on a desired current order potentiometer 21 by means of a switch 18. (An input representing the actual D.C. line current is derived by a transductor 10). Voltage limiting.-A voltage K 1 U applied at 31 limits the amplifier output to K 1 U and prevents overvoltage from the converter. Further limitation is provided by closing a switch device 17 to apply a voltage K 2 U in opposition to the conducting direction of diode 25. The voltage U is derived from the A.C. network by transformer 30 and rectifier 22. Arrangements are provided (Fig. 2, not shown) to increase the D.C. voltage if the A.C. network voltage decreases temporarily, by permitting the A.C. voltage sensor 30, 22 to influence the same switching members as the unit 12. The line protection unit 12 may be as described in Specification 853,912.
Patent GB-1501956-A (GB)
Title: Degassing apparatus for use with a dialyzer
IPC: B01D61/30
Filed: 1975-10-20
Abstract: In artificial kidneys, the dialysis solution pressure in the dialyser is stabilised to a value in the range between -500 and +200 mmHg and the flow rate of the dialysis solution is stabilised to a value in the range between 300 and 1000 ml/min. The pressure and the flow velocity of the dialysis solution in the dialyser (48) are controlled by the low pressure regulator (40) arranged upstream, the flow meter (66) arranged downstream and the pump (74) arranged further downstream. The arrangement of the flow meter (66) between the dialyser (48) and the pump (74) arranged downstream prevents the pump (74) from counteracting the low pressure regulator (40) by generating a low pressure in the dialyser (48). The control is preferably carried out only by the setting of the flow meter (66) arranged downstream. The flow meter (66) is arranged upstream with reference to a branch (70), at which branch (70) a degassing line (78) is connected to the line (68) containing the used dialysis solution. As a result, control is made possible of the flow velocity through the dialyser (48) independently of the degassing apparatus (26). <IMAGE>

Title: Camera adjustment
IPC: G03B27/34
Filed: 1961-12-06
Abstract: 950,994. Photographic apparatus, adjusting means. R. W. BORROWDALE. Dec. 6, 1961 [Dec. 7, 1960], No. 43767/61. Heading G2A. Photographic apparatus comprises a copyboard, photographic camera comprising a lens and film holder, a supporting frame for the copyboard and camera, and a rail connected to the frame on which carriage members supporting the copyboard, camera lens and film holder are slidably adjusted by means including a mounting bar parallel to the rail attached to the frame, detent means to hold a carriage member on the rail and to relocate it in a particular position, the detent means comprising a plunger carried by the carriage member and spring urged towards the mounting bar and adapted to engage a detent block adjustably positioned on the bar. In the embodiment shown in Fig. 1, a camera, comprising a movable lens holder 16, and a copy support 19 are mounted on a frame comprising uprights 10,11 and parallel bars 12,13, 50, 51. The lens holder 16 and copy support 19 are provided with pinions 18, 21 which run along rail 12 and adjusting means comprising plates 26, 70 on which are mounted plunger devices 28, 29, 71, 72 which co-operate with adjustable blocks 53, 73 on bars 50, 51 to set the lens and copy support correctly. Each plunger comprises a rod 41 with a tapered end which is spring urged towards one of bars 50, 51. By means of a pin 46 on the rod which engages an L-shaped slot in the support for the rod, the rod can be lifted against the spring and rotated into a locked position (cf plungers 29, 72) away from its rail by means of a knob 44. Therefore, by moving a block 53 or 73 along bar 50 or 51 and fixing it by means of a screw at a particular point the lens or copy support can be moved along rail 12 until, by unlocking a rod 41 the latter is spring urged downwards with its tapered end engaging a groove in the block. The position of the lens or support 19 can be read on scale 22 by means of indicators 23, 24. By keeping a particular block in a certain position a required setting can be easily relocated. Additional rods similar to rods 50, 51 together with additional plunge devices may be provided. In another embodiment shown in Fig. 5 a block 89 similar to a block 53, 73 is adjustable on a bar 81 removably attached to bar 80 which corresponds to bar 50 or 51. Having several detachable bars 81 removes the necessity of having a second bar similar to 80 with several blocks slidable on it. In another embodiment block 89 is replaced by a block 110 fixed to a micrometer 100 slidable along bar 81 by means of a block 95 which can be locked on to bar 81 at a required position to allow fine adjustment of block 110 and hence the camera lens 14 or copy support 19.

Title: A method of and an apparatus for detecting the position of the end of a coil of strip material
IPC: B21C47/34
Filed: 1969-09-04
Abstract: 1,247,296. Feeding webs. HITACHI Ltd. 4 Sept., 1969 [13 Sept., 1968; 11 Dec., 1968], No. 43936/69. Heading B8R. [Also in Division B3] A method of detecting the position of the outer end of a coil 1 of strip material comprises maintaining a support 30, Fig. 2, having a detector 34 in contact with the outer peripheral surface of the coil and rotating the coil in a direction opposite to the unwinding direction in order to detect the end with the detector. The position of the end of the coil 1 is detected by rotating the coil in the direction opposite to the unwinding direction so that the end 43 is moved past a keep roller 31 mounted on a pivoted support 30. A length of the coiled strip springs back due to its resilience and lifts a detector 34, pivoted on the support 30, against the biasing force of a spring 37. This displacement of the tip of the detector activates a limit switch 38 which controls the revolution of the coil so that the end 43 is placed half-way between the tip of the detector and a snubber roller 6. As the end 43 passes the detector 34, which is urged by the spring 37 to move downwardly until the rear portion of the detector engages a stopper 39, the limit switch 38 is restored to its original position. When the rotation of the coil 1 in the counterclockwise direction as seen in Fig. 2 is stopped the coil is rotated in the paying out direction for a predetermined time so as to start the unwinding. In a second embodiment, Fig. 3, the coil is again rotated in a direction opposite to the paying out direction and the end 59 is moved past the tip of a detector 54. This displaces the detector by a distance corresponding to a thickness of the strip and activates a limit switch 58 which controls the rotation of the coil as described above. As the end 59 moves past the tip of the pivoted support 50 the spring 57 causes the tip of the support 50 to move downwardly a distance corresponding to the thickness of the strip. This brings the support 50 and detector 54 into their original position thus rendering the limit switch 58 inoperative. In a third embodiment, Fig. 4, the coil 1 is rotated in a direction opposite to the paying out direction and the end 67 is moved past the detection end of a non-contact limit switch 66 mounted on a pivoted support 60. The limit switch is activated as the end 67 passes beneath it due to the outer periphery of the coil being increased by an amount corresponding to the thickness of the strip. Upon further rotation the end 67 moves past a roller 61 thus restoring the limit switch to its original position. In a fourth embodiment, Fig. 5, a limit switch 72 of the non-contact type, is placed on a support 70 having a roller 71 which is urged into contact with the coil by a spring 73. This embodiment operates in the same manner as the third embodiment.

As the electrode 2 melts the plasma zone between it and the molten pool in mould 1 moves upwards and the electrode 2 is moved downwards by vertical travel mechanism 7 which is connected thereto by rod 5 As shown, the a.c. source is initially connected between mould 1 and the electrode 2 which is mounted on the end of torch 3 by lamp 4 until the electrode 2 has been substantially consumed. At this point a switch 15 is actuated to interrupt the supply of current to electrode 2 and connect the plasma torch 3 in circuit. The plasma torch 3 supplies reduced heat to the ingot which eliminates the formation of damaging shrinkage cavities. In Fig. 2, not shown, the electrode 2-mould 1 has one supply and the torch 3 a separate supply. In this arrangement the torch 3 is energized throughout the process, initially to preheat the plasma forming gas supplied to consumable electrode 2, and finally, when the supply to the electrode 2 is cut off to eliminate shrinkage activities in the ingot.
