Abstract: 1313824 Making two-part couplings AMP Inc 15 Oct 1971 [6 Nov 1970] 47978/71 Heading B3A [Also in Division H2] A plug has a terminal in the form of a round hollow pin 2, rolled out of flat sheet, attached to U-shaped ferrules 8, 9 which receive the conductor and insulation of a wire. Between pin 2 and ferrule 8 is a transition portion 10, whose edges 12 merge into the edges 13 of the ferrule. Transition portion 10 is divided, for about half the circumference, from pin 2 by a slot 14. Pin 2 is open at the end nearer the ferrules and closed at the other end. In the manufacture of the plug, the terminal is first electroplated, e.g. with nickel, the electrolyte entering the interior of pin 2, and afterwards being removed, through the open end, these processes being assisted by a ventilation hole 6. Secondly the ferrules are crimped around the wire, and simultaneously transition portion 10 is crimped so as substantially to close off the end of pin 2. Finally the terminal is moulded into a plastics body, portion 10 in its crimped state serving to prevent the plastics material from entering the interior of the pin. The slot 14 allows spreading of portion 10 during crimping. Alternative embodiments have slots of different shapes.

Title: Electric circuit breaker with magnetically assisted closing means
IPC: H01H33/65
Filed: 1970-10-09
Abstract: 1319269 Automatic circuit breakers; vacuum switches GENERAL ELECTRIC CO 9 Oct 1970 [9 Oct 1969] 48087/70 Heading H1N A circuit breaker comprises electromagnetic means arranged to exert a closing force on the movable contact during closing but rendered ineffective during opening. The invention is described as applied to a vacuum switch having a fixed contact 11 and moving contact 12. The latter is closed by rotating a cam 50 bearing against a roller 52 to straighten the toggle 32, 34, thereby raising the rod 21 and closing the contacts through a lost-motion, prestressed spring assembly 22. Current is led to the moving contact through a flexible braid conductor 68 attached to pivoted links 74, 75 and set in a U-shaped configuration so as to exert a straightening thrust on the links and thus tend to close the contacts 11, 12 immediately they make contact. The switch is tripped by disengaging a pivoted latch 42 from a knee pivot 38 so that the linkage 32, 34, 39 collapses and the contacts are opened by opening spring 19. During the initial part of this opening movement the contacts 11, 12 are held closed by spring 26, while the rod 21 is moved downwards by the spring 19, and during this time a roller 90 rocks a latch 83 counter-clockwise so that the arm 80 is no longer supported and the sideways thrust of the conductor 68 on the links 74, 75 can no longer exert an upward thrust on the contact 12. Subsequently the latch 42 is returned to its latched position by spring 42a and latch 83 is restored during the initial part of the next closing movement of the rod 21.

Abstract: 1286256 Combine harvester MASSEY FERGUSON GmbH 2 Oct 1969 [11 Oct 1968] 48206/68 Heading A1F [Also in Division F2D] A combine harvester having a sensor detecting changes in crop intake rate and control means responsive to said sensor to vary ground speed and threshing rate, comprises a table elevator assembly 16 pivotable about 31 through a small angle and having electrical contacts 32, 33 which close when elevator 16 is fully up, as when a crop overload takes place. Closing said contacts activates solenoids 40, 41 in series with battery 42. Activation of the former solenoid causes a change in the transmission ratio to ground wheel 12 from engine 21 via variable V-belt drive 26 since swinging arm 29 is acted upon by hydraulic ram 35 controlled by control valve 38, itself being controlled by the solenoid 40, giving a reduction in ground speed. Activation of the latter solenoid adjusts governor 34 resulting in a higher engine speed, which causes an increase in operational speed of threshing drum 18, straw walkers 19, and shaker pan 20. Both solenoids are adjustable as to their extent of action to give a degree of control of the high/ low speed settings. Modifications include hydraulic or pneumatic circuits in conjunction with the sensor, use of two variable speed engines, and variable speed drive for the crop treating parts.
