Abstract: 1,250,838. Manipulator control handle. COMMISSARIAT A L'ENERGIE ATOMIQUE. 14 April, 1969 [22 May, 1968], No. 18895/69. Heading B8H. To cause the manipulator grab to engage an article, a trigger 39, Fig. 1, is pulled towards the handle 7. If movement of an operating cable 17 is insufficient to close the grab jaws a switch 41 is closed and this energizes a motor 19 which winds the cable 17 on to a winch 25. When the grab jaws contact the article the tension in the cable moves the trigger away against the resistance of the operator's finger and opens the switch 41. To release the article the operator allows the trigger to move further away, thus closing a switch 43 which causes the motor 19 to rotate the winch 25 in the reverse direction to pay out the cable 17. A spring 45 returns the trigger to the central position in which the motor is stationary. Fig. 2 (not shown) illustrates an arrangement in which the jaws are held closed when the operator releases the handle by means of an auxiliary motor switch which is only closed when the handle is gripped. In another embodiment, Fig. 3 (not shown), the cut-out switch of Fig. 2 is operated by the trigger 39. Fig. 4 shows a torque-limiter 59 provided in the motor drive shaft and the provision of a finger 53 on the winch drum 27 which cooperates with limit switches 55, 57 to prevent overwinding of the cable 17. In Fig. 5 the cable 17 passes round a winch 27 and is attached by a tensioning spring 65 to the handle.

Abstract: 1,250,988. Integrated circuit resistors. RCA CORPORATION. 14 Aug., 1969, No. 40799/69. Heading H1K. A semi-conductor integrated circuit device of the monolithic type includes two resistors of different value, the resistors being used in conditions such that the ratio between their values is of circuit significance. The invention relates to a method of constructing such a device so that discrepancies introduced during manufacture affect the two resistance values similarly whereby the ratio is held within acceptable limits. As shown, a silicon body 12 has a first resistor 14 and a second resistor 15 of lower value, the resistance ratio being 3 : 1. The resistors 14, 15 are formed by conventional photo-etching processes and comprise diffused regions 16, 30, respectively, adjacent the body surface 18, this surface having an insulating coating 20 of silicon dioxide. Openings 22, 24 in the coating 20 receive, respectively, portions 27, 29 of conductors 26, 28 to make contact with the ends of the resistor 14. The region 30 comprises three regions 31, 32, 33 separated by non- diffused regions 34, 35 and connected at their ends by enlarged diffused regions 36, 37. Openings 38, 39 in the coating 20 above the regions 36, 37 receive, respectively, portions 40, 42 of conductors 26, 41 whereby the regions 31, 32, 33 are connected in parallel between the conductors. Each of the regions 31, 32, 33 has approximately the same thickness, width and length as the region 16 so that manufacturing discrepancies produce the same effect in each of the four regions and the ratio mentioned above is not disturbed. In another embodiment (Figs. 5, 6, not shown) having a 9 : 1 ratio, the single diffused region of the higher value resistor has a length equal to three times that of the three parallel-connected regions of the lower value resistor. To maintain this ratio, manufacturing discrepancies are allowed for by providing two openings in the coating 20 above the single diffused region at positions so as to divide this region into three equal parts between the conductors connected to the ends of the region, conducting members being positioned in each of the two openings.

Abstract: 1,252,572. Static converters. NATIONAL RESEARCH DEVELOPMENT CORP. 28 April, 1969 [6 May, 1968], No. 21339/68. Heading H2F. Current harmonics produced by a polyphase static converter and which can cause serious interference in A.C. mains connected thereto, are reduced by injecting current into the converter circuit at 3 times the A.C. line frequency or a multiple of three times. In the rectifier arrangement shown in Fig. 1 the injected current is provided by a harmonic generator 9 connected in parallel with an interphase transformer between the star points of two secondary windings coupled to a common primary winding. The generator may be a motor-generator set or a static frequency generator. The interphase transformer 19, 20 has a selectively high impedance to the injected current which will thus flow mainly through the secondary windings in a path depending upon which rectifiers (e.g. diodes or thyristors) are conducting. For instance, with rectifiers 21, 22 conducting the injected current will flow in a path indicated by dotted line 10. An equivalent balancing current will flow in the corresponding primary winding phases thus modifying the primary waveform. The peak value (y) of the injected current should be in the order of one half the converter load current (2h) and should be phase displaced from the interphase transformer magnetizing current, e.g. by an angle of 90 degrees for unretarded rectification. The angle is adjusted for any change in the firing angle of the rectifiers. A table 1 (not shown) gives the harmonics present as percentages of the fundamental with various values of the injection ratio (y/h). In a polyphase full wave bridge rectifier arrangement (Fig. 2, not shown) the interphase transformer is dispensed with. The arrangement described is also used when inverting.

The locking mechanism comprises a strip 18 mounted on the feeler arm by spring strip 19, a pivoted lever 23, a spring 20 urging lever 23 clockwise to frictionally grip strip 18 between anvils 21, 24, and an electromagnet 2 for releasing the locking mechanism. The position of the feeler arm is sensed by means of a pneumatic nozzle 7 supplied with compressed air through regulator 40, constriction 6 and conduit 5 and co-operating with a plate 16. A gauge 3, which indicates the pressure in nozzle 7 and issues a control signal to the grinding machine when the parts 38 have been ground to the required size, is connected to conduit 5 via an electromagnetic valve 9 and a pneumatic valve 10, the control chamber of the latter being connected to conduit 5. Electromagnet 2 and electromagnetic valve 9 are actuated for short periods t 1  and t 3  respectively (Figs. 3 and 4) at regular intervals by means of a program device 4 which includes a motor 30 driving a pair of cams 28, 29 with lobes which operate switches 31, 32 (Fig. 2, not shown). Release of the feeler arm 13 in periods t 1  allows the feeler arm to adjust to the height of parts 38 either by abutting a part 38 during period t 1  or by falling into a gap between parts during period t 1  and being cammed to the correct position by one of the parts 38 during period t 2 . During periods t 1  and t 2  valve 9 is closed, and valve 9 is only opened during period t 3  so that gauge 3 does not register any pressure fluctuations caused by feeler arm 13 registering a gap between parts 38. If the feeler arm should register with a gap between parts 38 sufficiently large that tip 14 is still in the gap at the end of period t 2 , the pressure in conduit 5 will be sufficiently low for pneumatic valve 10 to maintain the position in which it closes conduit 8, and gauge 3 will not be connected to conduit 5. The pneumatic measuring system may be replaced by an inductive or capacitative system.
